TABLE OF CONTENTS

ABOUT THIS PROSPECTUS SUPPLEMENT AND THE PRICING SUPPLEMENTS

          This document is a prospectus supplement and supplements a prospectus which is part of the registration statement that we and PFG have filed with the SEC. This prospectus supplement provides you with a general description of the notes being offered, through newly established separate and distinct trusts and the underlying funding agreements and guarantees, and supplements the description of the notes, the underlying funding agreements and guarantees contained in the accompanying prospectus. These notes may be offered from time to time, through trusts, in one or more series of notes with a total initial public offering price or purchase price of up to $5,000,000,000 or the equivalent amount in one or more foreign or composite currencies, less any principal amount of notes previously issued under this program pursuant to this prospectus supplement, our Principal^® Life CoreNotes^® program issued primarily to retail investors pursuant to a separate prospectus supplement dated the date hereof, our secured medium-term notes retail program issued primarily to retail investors pursuant to a separate prospectus supplement dated the date hereof or otherwise under the accompanying prospectus.

          The specific terms and conditions of notes being offered and the related funding agreement and guarantee will be contained in a pricing supplement. A copy of that pricing supplement will be provided to

you along with a copy of this prospectus supplement and the accompanying prospectus. That pricing supplement also may add, update, supplement or clarify information in this prospectus supplement and the accompanying prospectus. You should carefully review such additional, updated, supplemental or clarifying information contained in the pricing supplement. You should read this prospectus supplement and the accompanying prospectus and the pricing supplement together with the additional information that is incorporated by reference in this prospectus supplement and the accompanying prospectus. That additional information is described under the heading “Incorporation of Certain Documents by Reference” beginning on page 12 of the accompanying prospectus.

          You should rely only on the information incorporated by reference or provided in this prospectus supplement, the accompanying prospectus and the applicable pricing supplement. None of us, PFG, any trust or any Agent has authorized any other person to provide you with different or additional information. If anyone provides you with different or additional information, you should not rely on it. None of us, PFG, any trust or any Agent is making an offer to sell the notes in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and the applicable pricing supplement, as well as information PFG previously filed with the SEC and incorporated by reference, is accurate only as of its respective date. The business, financial condition, results of operations and prospects of us and PFG may have changed since that date.

          In this prospectus supplement, references to “Principal Life,” “we,” “us” and “our” are to Principal Life Insurance Company, an Iowa life insurance company, references to “PFG” are to Principal Financial Group, Inc., a Delaware corporation and our indirect parent company, and references to “trust” are to the applicable newly established separate and distinct special purpose common law trust, formed in a jurisdiction located in the United States of America specified in the applicable pricing supplement, which actually issues the applicable series of notes. In this prospectus supplement, we refer to each series of Secured Medium-Term Notes as a “series of notes” and to Secured Medium-Term Notes in general as “notes.”

          In this prospectus supplement, references to “United States dollars,” “U.S. dollars” or “$” are to lawful currency of the United States of America, and references to “euros” are to the currency introduced at the start of the third stage of the European economic and monetary union pursuant to the treaty establishing the European Community, as amended.

The Trusts		Each series of notes will be issued by a newly established and separately created common law trust. Each trust will be established by GSS Holdings II, Inc., as trust beneficial owner, and U.S. Bank Trust National Association, as trustee, pursuant to a trust agreement (each, a “trust agreement”). The assets and liabilities of each trust are separate and distinct from the assets and liabilities of every other trust, us and PFG.
The Sponsor and the Depositor		We are the sponsor of the program and a registrant as the depositor and issuer of the funding agreements under the program.
The Guarantor		PFG is a registrant as the issuer of the guarantees that will fully and unconditionally guarantee our payment obligations under the funding agreements.
Purpose of Trusts		The sole purpose of each trust is to facilitate a program for the issuance of notes to the public. Each trust may only issue one series of notes and such notes will be issued only on the original issue date for such notes. Each series of notes will be secured by only one funding agreement purchased from us by the applicable trust, the principal amount of which may not be increased. Our payment obligations under each funding agreement will be fully and unconditionally guaranteed by PFG. The trust will use the net proceeds received from issuing a series of notes to acquire a funding agreement for, and to be held in, the trust. The trust will hold the collateral described below pertaining to the applicable series of notes to fund its obligations under that series of notes. Notes issued by the trust will be the direct obligations of the trust and will not be the obligations of any other trust, us or PFG. Holders of notes of a particular series may only look to the funding agreement issued by us, the related guarantee issued by PFG and any proceeds of such funding agreement and guarantee held in the related trust for payment on their notes and not to the assets held in any other trust or by us or PFG.
		We and PFG are not affiliated with any trust. Neither we, PFG nor any of our officers, directors, subsidiaries or affiliates owns any beneficial interest in any trust nor has any of these persons or entities entered into any agreement with any trust other than in furtherance of the issuance of notes from time

	to time as contemplated by this prospectus supplement and the accompanying prospectus.

		Neither we, PFG nor any of our officers, directors, subsidiaries or affiliates is affiliated with the trustee, the trust beneficial owner or the indenture trustee relating to the notes.
		Below is a diagram showing the parties involved in the issuance of notes by each trust.

We Can Issue Medium-Term Notes and Funding Agreements Directly to Investors		We are able to issue our own medium-term notes directly to investors and do issue funding agreements directly to investors. However, by securing each trust’s notes with a funding agreement, such trust’s notes are secured by an asset that would have a higher priority in insolvency than our unsecured medium-term notes, if any, and may be entitled to receive a higher investment rating from one or more nationally recognized rating agencies than our unsecured medium-term notes. In addition, funding agreements are very difficult to transfer and have no active secondary market. By securing each trust’s notes with a funding agreement, investors may be able to avail themselves of many of the benefits of our funding agreements while benefiting from the liquidity afforded by each trust’s medium-term notes.

Secured Medium-Term Notes Program		This prospectus supplement relates to notes that one or more trusts may issue and sell to United States and foreign institutional and other investors under our secured medium-term notes program.
Principal® Life CoreNotes® Program		Included in the registration statement, of which this prospectus supplement is a part, is another prospectus supplement relating to notes that may be issued and sold to retail investors by newly established trusts under the related Principal® Life CoreNotes® program. The terms of the Principal® Life CoreNotes® are identical in all material respects to the terms of the notes to be sold under this program, as described in this prospectus supplement, except that the Principal® Life CoreNotes®:
		• may not be issued as amortizing notes;
		• will be denominated in U.S. dollars only;
		• will not provide for the payment of additional amounts relating to any required withholding under any circumstances; and
		• may contain a survivor’s option, permitting optional repayment of notes of a series of notes, subject to certain limitations, prior to maturity, if requested, following the death of the beneficial owner of notes of that series of notes.
Secured Medium-Term Notes Retail Program		Included in the registration statement, of which this prospectus supplement is a part, is another prospectus supplement relating to notes that may be issued and sold to retail investors by newly established trusts under the related secured medium-term notes retail program. The terms of the secured medium-term notes retail program are identical in all material respects to the terms of the notes to be sold under this program, as described in this prospectus supplement, except that the secured medium-term retail notes:
		• may not be issued as amortizing notes;
		• will be denominated in U.S. dollars only;
		• will not provide for the payment of additional amounts relating to any required withholding under any circumstances; and
		• may contain a survivor’s option, permitting optional repayment of notes of a series of notes, subject to certain limitations, prior to maturity, if requested, following the death of the beneficial owner of notes of that series of notes.
Amount		The trusts may collectively issue up to a maximum aggregate principal amount of $5,000,000,000 of notes, or the equivalent in one or more foreign or composite currencies, in connection with this prospectus supplement, less any principal amount of

		notes previously issued under this program pursuant to this prospectus supplement, our Principal® Life CoreNotes® program pursuant to a separate prospectus supplement dated the date hereof, our secured medium-term notes retail program pursuant to a separate prospectus supplement dated the date hereof or otherwise under the accompanying prospectus.
Flow of Funds		Other than during the occurrence and continuance of an event of default under the notes of a trust, amounts received by or on behalf of the trust will be paid:
		• first, to amounts due under the notes; and
		• second, with respect to any remaining funds, in accordance with the applicable trust agreement.
		During the occurrence and continuance of an event of default under the notes of a trust, amounts received by or on behalf of the trust will be paid:
		• first, to the payment of the reasonable and customary expenses and counsel fees incurred by the indenture trustee and any other amounts due and unpaid to the indenture trustee, in an aggregate amount of no more than $250,000 for all notes issued under the program, to the extent not paid pursuant to the applicable expense and indemnity agreement;
		• second, to amounts due under the notes; and
		• third, with respect to any remaining funds, in accordance with the applicable trust agreement.
		See “Description of the Notes — Application of Money Collected Under the Indenture” in the accompanying prospectus.
		Since we and PFG are registrants, purchasers of notes may proceed directly against us and PFG to enforce their rights under the United States federal and state securities laws. The right of such purchasers to proceed against us, with respect to the applicable funding agreement, under the United States federal and state securities laws, is no different than if we had issued the funding agreement directly to such purchasers. The right of such purchasers to proceed against PFG, with respect to the applicable guarantee, under the United States federal and state securities laws is no different than if PFG had issued the guarantee directly to such purchasers.
Terms of the Notes: Status		• Each series of notes will be the unconditional, direct, non-recourse, secured and unsubordinated obligations of the applicable trust. Each series of notes will be secured by the collateral relating to that series of notes.

		• Each series of notes may be accelerated in the payment of principal and outstanding interest if an event of default under the notes occurs. Upon the occurrence of an event of default, the indenture trustee (described below), on behalf of the holders of such notes, may only proceed against the collateral held in the related trust.
		• The notes of each series are not, and will not be, obligations of, or guaranteed by, us or any other insurance company or any affiliate of ours, including PFG. The notes will not benefit from any insurance guarantee fund coverage or any similar protection.
Payment of Principal and Interest		• Principal and interest payments, if any, on any series of notes will be made solely from the proceeds of a funding agreement purchased with respect to such series of notes for, and to be held in, the related trust and the full and unconditional guarantee issued by PFG of our payment obligations under the relevant funding agreement.
		• Each series of notes may be interest bearing or non-interest bearing as specified in the applicable pricing supplement. Each series of notes may bear interest at either a fixed rate or a floating rate, or a combination of fixed rates and floating rates, as specified in the applicable pricing supplement.
		• The principal amount of each note (other than amortizing notes) will be payable on its stated maturity date, repayment date or redemption date, as specified in the applicable pricing supplement, at the corporate trust office of the paying agent, acting in its capacity as servicer, or any other place the relevant trust designates.
		• Unless otherwise specified in the applicable pricing supplement, interest, if any, on each series of notes will be payable on a monthly, quarterly, semi-annual or annual basis.
		• A trust may issue amortizing notes that pay an amount in respect of both interest and principal amortized over the life of the note as specified in the applicable pricing supplement.
Interest Rate		Each fixed rate note will bear interest from its date of issue at the rate(s) stated in the applicable pricing supplement until the principal is paid. Each floating rate note will bear interest from the date of original issuance until the principal is paid at a rate determined by reference to an interest rate or interest rate

	formula, which may be adjusted by a spread and/or spread multiplier (each as more fully described under “Description of the Notes”). The applicable pricing supplement will designate one or more of the following interest rate bases along with the index maturity for that interest rate basis:

		• the CD Rate;
		• the CMT Rate;
		• the Commercial Paper Rate;
		• the Constant Maturity Swap Rate;
		• the Eleventh District Cost of Funds Rate;
		• the Federal Funds Open Rate;
		• the Federal Funds Rate;
		• LIBOR;
		• EURIBOR;
		• the Prime Rate; or
		• the Treasury Rate.
		Interest, if any, will be payable monthly, quarterly, semi-annually or annually on each interest payment date and on the maturity date or, if applicable, earlier redemption or repayment, and, with respect to fixed rate notes, will be computed on the basis of a 360-day year of twelve 30-day months, unless otherwise specified in the applicable pricing supplement.
Maturities		Unless otherwise specified in the applicable pricing supplement, each series of notes will mature between nine months and 30 years from its date of original issuance on the last scheduled interest payment date, as specified in the applicable pricing supplement.
Redemption and Repayment		A trust will redeem its series of notes if we redeem the funding agreement securing such series of notes. Except as otherwise specified in the accompanying prospectus, this prospectus supplement or the applicable pricing supplement, the funding agreement securing a series of notes will not be redeemable by us and no series of notes will be repayable at the option of the holder prior to their stated maturity date. Unless otherwise specified in the applicable pricing supplement, the notes will not be subject to any sinking fund.
		Each trust may issue a series of notes which may be redeemed by the issuing trust when 20% or more of the original principal balance is outstanding. Notes that may be redeemed at a time when 20% or more of the original principal amount of such notes are outstanding will be designated in their title as “callable” in the applicable pricing supplement.

Withholding Tax		All amounts due in respect of the notes of any series, the related guarantee and the related funding agreement will be made without any applicable withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of any governmental authority, unless such withholding or deduction is required by law. Unless otherwise specified in the applicable pricing supplement, none of the notes, the related guarantee or the related funding agreement will provide for the payment of additional amounts relating to any required withholding or deduction imposed or levied on payments in respect of a series of notes, the related guarantee or the related funding agreement. As a result, unless otherwise specified in the applicable pricing supplement, the risk of any such withholding or deduction, whether or not as a result of a change in law or otherwise, will be borne by the holders of such series of notes.
Material United States Federal Income Tax Considerations		We intend to take the position, for United States federal income tax purposes, that each trust will be disregarded and that the notes will be treated as representing our indebtedness (the “Intended Tax Characterization”). Each holder of a note (or any beneficial interest therein), by acceptance of the note (or beneficial interest therein), agrees to the Intended Tax Characterization. Accordingly, holders of the notes generally will have the same United States federal income tax consequences from the purchase of the notes as they would have had if they purchased a debt obligation issued directly by us. Prospective purchasers of the notes must carefully consider the tax consequences of the ownership and disposition of the notes set forth under “Material United States Federal Income Tax Considerations.”
Fees and Expenses		We will pay the costs and expenses incurred by a trust under the expense and indemnity agreements with each of the indenture trustee, the custodian, the trust beneficial owner and the trustee (on behalf of itself and each trust formed in connection with the issuance of a series of notes) and any additional service provider appointed from time to time.
		Under each expense and indemnity agreement, we will pay certain costs and expenses relating to the offering, sale, issuance and administration of any series of notes and certain costs, expenses and taxes incurred by a trust and will indemnify the indenture trustee, the custodian, the trust beneficial owner, the trustee, each trust and additional service providers appointed from time to time with respect to certain matters. See “Fees and Expenses” in the accompanying prospectus.
		We anticipate that the indenture trustee fees for the program will be approximately $215 per year for each series of notes.

Denominations; Currency		Unless otherwise specified in the applicable pricing supplement, the notes will be denominated in U.S. dollars and sold in denominations of $1,000 and integral multiples of $1,000 in excess thereof.
Listing		Unless otherwise specified in the applicable pricing supplement, your series of notes will not be listed on any securities exchange.
Form of Notes		Unless otherwise specified in the applicable pricing supplement, each series of notes will be issued in fully registered form and will be initially represented by one or more book-entry notes registered in the name of Cede & Co., the nominee of The Depository Trust Company, as depositary. Each book-entry note will be held by the indenture trustee as custodian for the depositary or its nominee.
Clearing Systems		The Depository Trust Company and/or, in relation to any series of notes, any other clearing system as may be specified in the applicable pricing supplement.
Collateral		The notes of any series will be secured by the right, title and interest of the applicable trust in and to (1) the relevant funding agreement held in that trust, (2) the related guarantee issued by PFG to the trust fully and unconditionally guaranteeing our payment obligations under the funding agreement, (3) all proceeds of the funding agreement and the guarantee and all amounts and instruments on deposit from time to time in the related collection account, (4) all books and records pertaining to the relevant funding agreement and the related guarantee and (5) all rights of the trust pertaining to the foregoing.
		Each series of notes will be secured by the collateral held in the applicable trust. The trust will collaterally assign and grant a security interest in the related funding agreement and the related guarantee in favor of the indenture trustee for the benefit of the holders of notes of the applicable series.
		Under the custodial agreement (the “custodial agreement”) entered into among the indenture trustee, Bankers Trust Company, N.A. (the “custodian”) and the trustee (on behalf of each trust to be formed in connection with the issuance of a series of notes), upon the collateral assignment of and grant of security interest in the funding agreement and the guarantee related to a series of notes of a trust, the custodian will hold the funding agreement and the guarantee, on behalf of the indenture trustee in the State of Iowa.
Funding Agreements		A funding agreement is a type of insurance company product in which the purchaser, usually an institutional investor, pays the insurance company a deposit and, in turn, receives scheduled payments of principal and interest. The deposit we receive on the issuance of a funding agreement will be part of our general account and not allocated to any of our separate accounts. Our general account is the account which contains

		all of our assets and liabilities other than those held in our separate accounts. (Separate accounts are segregated accounts which are established for certain products that we sell. A separate account holds assets and liabilities specifically related to one or more products and segregates these assets and liabilities from the assets and liabilities of all other separate accounts and the assets and liabilities of our general account.) Since the deposit made under any funding agreement will be part of our general account, our obligations under each funding agreement will be the obligations of our general account, rather than the obligations of any separate account. As such, we will invest the proceeds from the sale of funding agreements in a portfolio of assets which along with our other general account assets will be used to meet our contractual obligations under the funding agreements and our other general account obligations. We will earn the spread differential between the cost of our obligations under the funding agreements and the yield on our invested assets. We may periodically, consistent with our past practice and subject to all applicable regulatory restrictions on our insurance operations, dividend a portion of the spread income to PFG.
		Each trust will use the net proceeds received from the sale of its series of notes to purchase a funding agreement issued by us, the terms of which will be set forth in the applicable pricing supplement. The funding agreement will have a deposit amount equal to the sum of the principal amount (or issue price in the case of discount notes) of the related series of notes and the amount of the beneficial interest in the related trust. The rate at which the funding agreement bears interest will be equal to the rate of interest, if any, on the related series of notes. The funding agreement will otherwise have substantially similar payment and other terms to the related series of notes.
		Each funding agreement is our unsecured obligation. See “— Ratings” below.
		In the event of our impairment or insolvency, the Iowa Insurance Commissioner will be authorized and directed to commence delinquency proceedings for the purpose of liquidating, rehabilitating, reorganizing or conserving us pursuant to Iowa Code Sections 507C.4, 507C.12, 507C.13, 507C.14 and 507C.16. In conducting delinquency proceedings, claims are prioritized and an order of distribution is specified pursuant to Iowa Code Section 507C.42. There are nine classes within the priority scheme, with each successive class being fully junior to the preceding class. Class 1 priority is given to the costs and expenses of administration of the insurer during the delinquency proceedings and Class 2 priority is given to the claims of the insurer’s policyholders and guaranty associations. We believe that, in a properly prepared and presented case, a court applying Iowa law would conclude that loss claims of principal and interest in respect

		of each funding agreement would be accorded Class 2 priority under Iowa Code Section 507C.42 and paid equally in priority with our other policyholders. See “Description of the Funding Agreements” in the accompanying prospectus.
		Iowa law would apply to our insolvency or receivership proceedings. Investors should note, however, that the statutory liquidation priority accorded to funding agreements under Iowa law does not clearly apply to any additional amounts required to be paid (if specified in the applicable pricing supplement and related funding agreement) as may be necessary in order that the net amounts receivable by a holder after any withholding or deduction shall equal the respective amounts which would have been receivable by such holder in the absence of such withholding or deduction. Accordingly, in the event of our insolvency or receivership, claims under a funding agreement for such payments, if any, may not rank equally with either life insurance policy and annuity claims or funding agreement claims, and may rank equally with our unsecured debt obligations, which are given Class 5 priority under Iowa Code Section 507C.42. See “Description of the Funding Agreements” in the accompanying prospectus.
Guarantees		Our payment obligations under the funding agreement issued to each trust will be fully and unconditionally guaranteed by PFG under a guarantee issued by PFG to the trust as described in the accompanying prospectus. Each guarantee will be an unsecured, unsubordinated, contingent obligation of PFG. See “Description of the Guarantees” in the accompanying prospectus.
Ratings		Unless otherwise indicated in the applicable pricing supplement, the notes will have an issue credit rating of AA from Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc. (“Standard & Poor’s”). Standard & Poor’s has rated the program AA. If Standard & Poor’s changes the program rating, the new program rating will be specified in the applicable pricing supplement. We expect the program to be rated Aa2 by Moody’s Investors Service, Inc. (“Moody’s”). If Moody’s changes the program rating, the new program rating will be specified in the applicable pricing supplement. Notes of a series will be issued under the program only in the event that, at the time of issuance of such series of notes, at least one nationally recognized rating agency would assign an investment grade rating to such series of notes and the funding agreement securing such series of notes.
Indenture, Indenture Trustee and Servicer		Each trust will issue its series of notes to the public pursuant to an indenture between that trust and Citibank, N.A., in its capacity as indenture trustee. See “Description of the Notes — General — Indenture.” The indenture trustee will act as servicer with respect to the program. The indenture is subject to the Trust Indenture Act of 1939, as amended. The

		indenture trustee is not affiliated with any trust, with us or PFG.
Administration of the Trusts		U.S. Bank Trust National Association, a national banking association, will be each trust’s sole trustee (the “trustee”). The trustee will not be obligated in any way to make payments under or in respect of the notes. The trustee is not affiliated with us or PFG.
Trust Beneficial Owner		GSS Holdings II, Inc., a Delaware corporation, will be the sole beneficial owner of each trust (the “trust beneficial owner”). The beneficial interest of each trust:
		• will be purchased by the trust beneficial owner for $15 (or in the case of a trust that issues discount notes, such other amount as corresponds to the discount on such notes), unless otherwise specified in the applicable pricing supplement;
		• will be issued in book-entry form only;
		• will entitle the trust beneficial owner to receive payments in respect thereof on the same terms as the payments to be made to the holders of notes of the related series; and
		• will be subordinated to the related series of notes.
		The trust beneficial owner will receive periodic distributions on its beneficial interest at the same rate and on the same day that holders of notes of the related series receive interest payments. On the maturity date of the trust beneficial owner’s beneficial interest and the related series of notes, the trust will redeem the principal amount of the related series of notes to the holders of such notes and the principal amount of the beneficial interest to the trust beneficial owner.
		The trust beneficial owner is not affiliated with us or PFG.
Governing Law		The notes and each indenture will be governed by, and construed in accordance with, the laws of the State of New York. Each guarantee issued by PFG will be governed by, and construed in accordance with, the laws of the State of New York. The trust agreement for the applicable trust will be governed by, and construed in accordance with, the laws of the jurisdiction in which it is formed. Each funding agreement will be governed by the laws of the State of Iowa.

DESCRIPTION OF THE NOTES

          The following description of the material provisions of the notes supplements the general description of the notes provided in the accompanying prospectus. You should therefore review the accompanying prospectus carefully. You should carefully review the information in this prospectus supplement. The pricing supplement for each offering of notes will contain the specific information and terms and conditions for that offering. As such, you should carefully review the information contained in the pricing supplement, including any description of the method of calculating interest on any note. The applicable pricing supplement may also add, update, supplement or clarify information contained in this prospectus supplement or the accompanying prospectus. It is important for you to consider the information contained in the accompanying prospectus, this prospectus supplement, the applicable pricing supplement, the indenture and the notes in making your investment decision.

          This section describes some technical concepts and uses some capitalized terms that are not defined in this prospectus supplement. You should refer to the form of indenture and the form of note certificates filed as exhibits to the registration statement (of which this prospectus supplement and the accompanying prospectus are a part) for the full description of those concepts and complete definitions of these terms.

General

          Each trust will issue one series of notes, subject to and entitled to the benefits of a separate indenture between the trust and the indenture trustee, which will adopt and incorporate the standard indenture terms. Such notes will be issued only on the original issue date for such notes. With respect to a particular trust, we refer to the applicable indenture and the standard indenture terms as the “indenture.” Each series of notes will be the subject of a pricing supplement. The indenture is subject to, and governed by, the Trust Indenture Act of 1939, as amended. For a description of the terms of the indenture, see “Description of the Notes” beginning on page 22 of the accompanying prospectus.

          At the date of this prospectus supplement, the notes offered pursuant to this prospectus supplement are limited to an aggregate initial public offering price or purchase price of up to $5,000,000,000, or its equivalent in one or more foreign or composite currencies. This amount is subject to reduction as a result of the issuance of notes previously under this program, our Principal^® Life CoreNotes^® program, our secured medium-term notes retail program or otherwise under the accompanying prospectus.

          The notes of a series will be the trust’s unconditional, direct, non-recourse, secured and unsubordinated obligations. Under the indenture, the funding agreement issued to and deposited into a trust by us, in exchange for the proceeds received by the trust from the offering of its series of notes and trust beneficial interest, will be collaterally assigned by the trust, and the trust will grant a security interest in the funding agreement, to the indenture trustee for the benefit of the holders of the related series of notes. A trust may purchase only one funding agreement from us and the principal amount of the funding agreement may not be increased. The trust will also collaterally assign and grant a security interest in the guarantee issued by PFG to the trust in favor of the indenture trustee for the benefit of the holders of the related series of notes. Each series of notes will be secured by a security interest in the “collateral,” consisting of:

          Under the custodial agreement, upon the collateral assignment and grant of security interest in the funding agreement and the guarantee related to a series of notes of a trust, the custodian will hold the funding agreement and the guarantee, on behalf of the indenture trustee in the State of Iowa.

          The notes of a series of a trust will rank equally among themselves.

          Notes that bear interest will either be fixed rate notes or floating rate notes, or a combination of fixed rate and floating rate, as specified in the applicable pricing supplement. A trust may also issue discount notes and amortizing notes as specified in the applicable pricing supplement.

          The pricing supplement relating to the offering of a series of notes will describe the following terms:

          Unless otherwise specified in the applicable pricing supplement, each series of notes will mature on a day between nine months and 30 years from its date of original issuance on the last scheduled interest payment date (the “stated maturity date”), as specified in the applicable pricing supplement, unless the principal of such series becomes due and payable prior to the stated maturity date, whether, as applicable, by the declaration of acceleration of maturity, notice of redemption by the trust, notice of the registered holder’s option to elect repayment or otherwise (we refer to the stated maturity date or any date prior to the stated maturity date on which the particular series of notes becomes due and payable, as the case may be, as the “maturity date” with respect to the principal of such series of notes repayable on that date).

          Unless otherwise specified in the applicable pricing supplement, the notes of a series will be denominated in, and payments of principal, premium, if any, and/or interest, if any, in respect thereof will be made in, United States dollars. In the alternative, each series of notes may be denominated in, and payments of principal, premium, if any, and/or interest, if any, in respect thereof may be made in, a single foreign currency. The currency in which a particular series of notes is denominated (or, if that currency is no longer legal tender for the payment of public and private debts in the country issuing that currency or, in the case of the euro, in the member states of the European Union that have adopted the single currency in accordance with the treaty establishing the European Community, as amended by the treaty on European Union, the currency which is then legal tender in the related country or in the adopting member states of the European Union, as the case may be) is referred to as the “specified currency” with respect to such series of notes.

          You will be required to pay for your notes in the specified currency. At the present time, there are limited facilities in the United States for the conversion of United States dollars into foreign currencies and vice versa, and commercial banks do not generally offer non-United States dollar checking or savings account facilities in the United States. The Agent from or through which a foreign currency note is purchased may be prepared to arrange for the conversion of United States dollars into the specified currency in order to enable you to pay for your foreign currency note, provided that you make a request to that Agent on or prior to the fifth business day (as defined below) preceding the date of delivery of the particular foreign currency note, or by any other day determined by that Agent. Each conversion will be made by an Agent on the terms and subject to the conditions, limitations and charges as that Agent may from time to time establish in accordance with its regular foreign exchange practices. You will be required to bear all costs of exchange in respect of your foreign currency note.

          A trust may (if so specified in the applicable pricing supplement), without the consent of the holders of any note, redenominate all, but not less than all, of the notes of any series on or after the date on which the member state of the European Union in whose national currency such notes are denominated has become a participant member in the third stage of the European economic and monetary union as more fully set out in the applicable pricing supplement.

          Each trust will issue each note as a book-entry note represented by one or more fully registered global securities, unless otherwise specified in the applicable pricing supplement. Unless otherwise specified in the applicable pricing supplement, the minimum denominations of each note will be $1,000 and integral multiples of $1,000 in excess thereof.

          Unless otherwise specified in the applicable pricing supplement, your series of notes will not be listed on any securities exchange.

          A trust will make payments of principal of, and premium, if any, and interest and other amounts due and owing, if any, on book-entry

notes through the indenture trustee, acting in its capacity as servicer, to the account of the depositary or its nominee. See “— Book Entry Notes.” In the case of definitive notes, the trust will make payments of principal of, and premium, if any, and interest and other amounts due and owing, if any, on the maturity date in immediately available funds upon presentation and surrender thereof (and, in the case of any repayment on an optional repayment date, upon submission of a duly completed election form if and as required by the provisions described below) at the office or agency maintained by the trust for this purpose in the Borough of Manhattan, The City of New York, which is currently the paying agency office of the indenture trustee located at 111 Wall Street, 15th Floor, Zone 3, New York, New York 10005. A trust will make payments of interest and other amounts due and owing, if any, on the maturity date of a definitive note to the person to whom payment of the principal thereof and premium, if any, thereon shall be made. A trust will make payments of interest and other amounts due and owing, if any, on a definitive note on any Interest Payment Date (as defined below) other than the maturity date by check mailed to the address of the registered holder entitled thereto appearing in the note register. Notwithstanding the foregoing, the trust will make payments of interest and other amounts due and owing, if any, on a definitive note on any Interest Payment Date other than the maturity date to each registered holder of $10,000,000 (or, if the specified currency is other than United States dollars, the equivalent thereof in the particular specified currency) or more in aggregate principal amount of definitive notes (whether having identical or different terms and provisions) by wire transfer of immediately available funds if the applicable registered holder has delivered appropriate wire transfer instructions in writing to the indenture trustee not less than 15 calendar days prior to the particular Interest Payment Date. Any wire transfer instructions received by the indenture trustee shall remain in effect until revoked by the applicable registered holder.

          “Business day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York; provided, however, that, with respect to foreign currency notes, the day must also not be a day on which commercial banks are authorized or required by law, regulation or executive order to close in the Principal Financial Center (as defined below) of the country issuing the specified currency (or, if the specified currency is the euro, the day must also be a day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer (TARGET) System is open); provided, further, that, with respect to notes as to which LIBOR (as defined below) is an applicable Interest Rate Basis, the day must also be a London Banking Day, which means a day on which commercial banks are open for business (including dealings in the LIBOR Currency (as defined below)) in London.

          “Principal Financial Center” means, as applicable:

provided, however, that with respect to United States dollars, Australian dollars, Canadian dollars, the euro, South African rand and Swiss francs, the “Principal Financial Center” shall be The City of New York, Sydney, Toronto, London (solely in the case of the LIBOR Currency), Johannesburg and Zurich, respectively.

          Book-entry notes may be transferred or exchanged only through the clearing systems (described below). Registration of transfer or exchange of definitive notes will be made at the office or agency maintained by the trust for this purpose in the Borough of Manhattan, The City of New York, which is currently the corporate trust office of the indenture trustee located at 111 Wall Street, 15th Floor, Zone 3, New York, New York 10005. No service charge will be imposed for any such registration of transfer or exchange of notes, but the trust may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection there-

with (other than certain exchanges not involving any transfer).

Withholding Tax and Payment of Additional Amounts

          All amounts due in respect of the notes will be made without any applicable withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of any governmental authority, unless such withholding or deduction is required by law. Unless otherwise specified in the applicable pricing supplement, the trust will not pay any additional amounts to holders of any series of notes in respect of any such withholding or deduction, any such withholding or deduction will not give rise to an event of default or any independent right or obligation to redeem the notes of such series and each holder of a note of the applicable series will be deemed for all purposes to have received cash in an amount equal to the portion of such withholding or deduction that is attributable to such holder’s interest in the notes as equitably determined by the trust.

          If it is specified in the applicable pricing supplement and funding agreement that we have agreed to pay additional amounts to the trust to reflect any required withholding or deduction under the funding agreement and we are required, or based on an opinion of independent legal counsel selected by us a material probability exists that we will be required, to pay additional amounts in respect of such withholding or deduction, pursuant to (a) any amendment to, or change (including any announced prospective change) in, the tax laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein or (b) any amendment to, or change in, an interpretation or application of any such laws or regulations by any governmental authority in the United States, which amendment or change is enacted, promulgated, issued or announced on or after the effective date of the applicable funding agreement, we will have the right to redeem the affected funding agreement by giving not less than 30 and no more than 60 days prior written notice to the trust and by paying the trust the outstanding principal of, and accrued but unpaid interest on, the related funding agreement or such other amount as is specified in the applicable pricing supplement. If we redeem the related funding agreement issued to the trust, the related trust will redeem all of the notes of the applicable series as provided in the indenture. See “Description of the Funding Agreements — Early Redemption for Tax Event” in the accompanying prospectus.

Final European Union Withholding Tax System

          On July 1, 2005, a directive adopted by the European Council of Economics and Finance Ministers regarding the taxation of savings income took effect. The directive provides for the tax authorities of the European Union member states to provide each other with details of payments of interest and similar income made to individuals but permits Austria, Belgium and Luxembourg instead to impose a withholding tax on the payments concerned for a “transitional period” (although it provides that no such withholding tax should be levied where the beneficial owner of the payment authorizes an exchange of information and/or where the beneficial owner presents a certificate from the tax authority of the European Union member state in which the beneficial owner is resident). The directive does not preclude European Union member states from levying other types of withholding tax.

          For the avoidance of doubt, unless otherwise specified in the applicable pricing supplement, no trust will pay any additional amounts with respect to its series of notes should any deduction or withholding on account of tax be required to be made, or be made, pursuant to the directive.

Tax Redemption

          If a “tax event” as to the relevant funding agreement occurs, we will have the right to redeem the funding agreement and, upon such redemption, the applicable trust will redeem its series of notes in the same manner described under “— Optional Redemption; Optional Repayment; No Sinking Fund” below. For further discussion of “tax event” redemption, see “Description of the Funding Agreements — Early Redemption for Tax Event” in the accompanying prospectus.

Security; Non-Recourse Obligations

          Each series of notes will be solely the obligations of the related trust and will not be guaranteed by any person, including but not limited to us, PFG, any Agent, any of our or their affiliates or any other trust. A trust’s obligations under its series of notes will be secured by all of its rights and title in a funding agreement issued by us, the payment obligations of which are guaranteed by the related guarantee issued by PFG to the trust and other rights and assets included in the applicable collateral held in the trust.

          Since we will be the sole obligor under the funding agreement and PFG will be the sole obligor under the related guarantee, the trust’s ability to meet its obligations, and your ability to receive payments from the trust, with respect to the applicable series of notes, will be principally dependent upon our ability to perform our obligations under the applicable funding agreement held in the relevant trust and PFG’s ability to perform its obligations under the guarantee of our payment obligations under the related funding agreement. However, you will have no direct contractual rights against us or PFG under the funding agreement or the guarantee, respectively. Under the terms of the funding agreement and related guarantee, recourse rights to us or PFG, respectively, will belong to the trust, its successors and its permitted assignees, but only with respect to the relevant trust. In connection with the offering and sale of a series of notes, the trust will collaterally assign and grant a security interest in the relevant funding agreement for such series of notes to, and the trust will collaterally assign and grant a security interest in the related guarantee in favor of, the indenture trustee for the benefit of the holders of such series of notes. Accordingly, recourse to us under such funding agreement and to PFG under the related guarantee will be enforceable only by the indenture trustee as a secured party on behalf of the holders of such series of notes, or by the holders of such series of notes by directing the indenture trustee under the limited circumstances described in the accompanying prospectus under “Description of the Notes — Certain Rights of Holders.” See also “Description of the Notes — Nonrecourse Enforcement” in the accompanying prospectus.

          Since we and PFG are registrants, purchasers of notes may proceed directly against us and PFG to enforce their rights under the United States federal and state securities laws. The right by such purchasers to proceed against us, with respect to the applicable funding agreement, under the United States federal and state securities laws is no different than if we had issued the funding agreement directly to such purchasers. The right by such purchasers to proceed against PFG, with respect to the applicable guarantee, under the United States federal and state securities laws is no different than if PFG had issued the guarantee directly to such purchasers.

Optional Redemption; Optional Repayment; No Sinking Fund

          In the case of notes that are not discount notes, if an optional redemption date is specified in the pricing supplement relating to a series of notes, and we have redeemed the related funding agreement in full or part, as applicable, the related trust will redeem the series of notes secured by such funding agreement, in full or in part as applicable, prior to the stated maturity date of such series of notes. Such redemptions shall be made in whole or from time to time in part in increments of $1,000 or any other integral multiple of an authorized denomination specified in the applicable pricing supplement (provided that any remaining principal amount thereof shall be at least $1,000 or other minimum authorized denomination applicable thereto), at the applicable redemption price (as defined below), together with unpaid interest, if any, accrued thereon to, but excluding, the date of redemption. The trust must give written notice to the holders of the particular series of notes to be redeemed not more than 60 nor less than 30 calendar days prior to the date of redemption. “Redemption price,” with respect to a series of notes, means an amount equal to the initial redemption percentage specified in the applicable pricing supplement (as adjusted by the annual redemption percentage reduction, as described in the pricing supplement, if applicable) multiplied by the unpaid principal amount thereof to be redeemed. The initial redemption percentage, if any, applicable to a series of notes shall decline at each anniversary of the initial redemption date by an amount equal to the applicable annual redemption percentage reduction, if any,

until the redemption price is equal to 100% of the unpaid amount thereof to be redeemed.

          Each trust may issue a series of notes which may be redeemed by the issuing trust when 20% or more of the original principal balance is outstanding, which are referred to as “callable” notes and will be designated in their title as “callable” in the relevant pricing supplement. Unless otherwise specified in the relevant pricing supplement, such series of notes will otherwise be subject to the redemption provisions described herein. For a discussion of the redemption of discount notes, see “— Discount Notes.”

          If fewer than all of the notes are to be redeemed, DTC will select the notes to be redeemed not more than 60 calendar days prior to the redemption date by lot or, if the notes are not in book-entry form, the indenture trustee will do so, in its reasonable discretion, by lot or on a pro rata basis in accordance with its customary procedures. If any note is redeemed in part only, a new note in principal amount equal to the unredeemed principal portion will be issued.

          If an optional repayment right is specified in the pricing supplement relating to a series of notes, such notes may be subject to repayment at the option of the holders of such series of notes on any repayment date specified in the applicable pricing supplement. Exercise of the repayment option under the notes by the holders will also require the applicable trust to exercise a corresponding repayment under the applicable funding agreement. On any such repayment date, unless otherwise specified in the applicable pricing supplement, the notes shall be repayable in whole or in part in increments of $1,000 at the option of the holders thereof at a repayment price equal to 100% of the principal amount thereof to be repaid, together with interest thereon payable to the date of repayment. A holder of a series of notes exercising its repayment right must submit to the indenture trustee at its corporate trust office, or at such other place or places of which the relevant trust has notified such holder, the notes to be repaid together with the “option to elect repayment” form attached to the notes not more than 60 nor less than 30 calendar days prior to the date of repayment. Exercise of such repayment right by a holder shall be irrevocable. If a holder requests repayment in part only, a new note in principal amount equal to the principal portion of the notes not repaid will be issued.

          None of the trusts will issue notes that may be repaid at the option of the holders prior to the stated maturity if such issuance would cause the relevant trust to fail to satisfy the applicable requirements for exemption under Rule 3a-7 under the Investment Company Act of 1940, as amended, and all applicable rules, regulations and interpretations thereunder.

          Only DTC may exercise a repayment option in respect of notes issued in book-entry form. Accordingly, beneficial owners of notes that desire to exercise their repayment option, if any, with respect to all or any portion of such notes, must instruct the participant through which they own their interest to direct DTC to exercise the repayment option on their behalf by delivering the duly completed election form to the indenture trustee as aforesaid. In order to ensure that the election form is received by the indenture trustee on a particular day, the applicable beneficial owner must so instruct the participant through which it owns its interest before such participant’s deadline for accepting instructions for that day. Participants may have different deadlines for accepting instructions from their customers. Accordingly, a beneficial owner should consult the participant through which it owns its interest in the notes for the participant’s deadline for receiving payment instructions. In addition, at the time such instructions are given, each such beneficial owner will cause such participant to transfer such beneficial owner’s interest in the notes issued in book-entry form, on DTC’s records, to the indenture trustee.

          No series of notes will be subject to, or entitled to the benefit of, any sinking fund unless otherwise specified in the applicable pricing supplement. A trust may issue amortizing notes that pay a level amount in respect of both interest and principal over the life of the notes, if specified in the applicable pricing supplement. See “— Amortizing Notes.”

Purchase of Notes by Us

          We may at any time purchase notes at any price or prices in the open market or otherwise. Notes so purchased by us will be surrendered to the indenture trustee for cancellation. Concurrently with the surrender to the

indenture trustee of any note, the funding agreement related to such note will be similarly cancelled.

          If applicable, such trust will comply with the requirements of Section 14(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules promulgated thereunder, and any other securities laws or regulations in connection with any repurchase of the notes by us.

Interest

          Each interest-bearing series of notes will bear interest from its date of issue at the rate per annum, in the case of notes that bear interest at fixed rates, or pursuant to the interest rate formula, in the case of notes that bear interest at floating rates, in each case as specified in the applicable pricing supplement, until the principal thereof is paid or made available for payment. The trust will make interest payments in respect of each series of notes in an amount equal to the interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or from and including the date of issue, if no interest has been paid, to but excluding the applicable interest payment date or the maturity date, as the case may be (each, an “interest period”).

          Interest on each series of notes will be payable in arrears on each interest payment date, to the registered holder at the close of business on the regular interest record date (as defined below) (except that interest, if any, due at maturity will be paid to the person to whom the principal of the note is paid), and on the maturity date. The first payment of interest on any series of notes originally issued between a regular interest record date and the related interest payment date will be made on the interest payment date immediately following the next succeeding regular interest record date to the registered holder on the next succeeding regular interest record date. The “regular interest record date” shall be the day that is fifteen (15) calendar days preceding the applicable interest payment date, whether or not a business day.

Fixed Rate Notes

          In the case of each series of notes that bear interest at fixed rates, the applicable pricing supplement will specify the fixed interest rate per annum applicable to each note and the frequency with which interest is payable. Interest on each series of notes that bears interest at fixed rates will be computed on the basis of a 360-day year of twelve 30-day months.

          Unless otherwise specified in the applicable pricing supplement, the interest payment dates for fixed rate notes will be as follows:

          If any interest payment date or the maturity date of a series of notes that bear interest at fixed rates falls on a day that is not a business day, the applicable trust will make the required payment of principal, premium, if any, and/or interest or other amounts on the next succeeding business day, and no additional interest will accrue in respect of the payment made on that next succeeding business day.

          Interest rates that each trust offers on its fixed rate notes may differ from the rates offered by other trusts depending upon, among other factors, the aggregate principal amount of notes purchased in any single transaction. Notes with different variable terms other than interest rates may also be offered by other trusts concurrently to different investors. Other trusts may change interest rates or formulas and other terms of notes from time to time, but no change of terms will affect any note any other trust has previously issued or as to which any other trust has accepted an offer to purchase.

Floating Rate Notes

          Interest on each series of notes that bears interest at floating rates will be determined by reference to the applicable Interest Rate Basis or Interest Rate Bases, which may, as described below, include:

          The applicable pricing supplement will specify certain terms of the particular series of notes that bears interest at floating rates, including:

          The rate derived from the applicable Interest Rate Basis will be determined in accordance with the related provisions below. The interest rate in effect on each day will be based on:

          The “Spread” is the number of basis points (one one-hundredth of a percentage point) specified in the applicable pricing supplement to be added to or subtracted from the related Interest Rate Basis or Interest Rate Bases applicable to a series of notes that bears interest at floating rates. The “Spread Multiplier” is the percentage specified in the applicable pricing supplement of the related Interest Rate Basis or Interest Rate Bases applicable to a series of notes that bears interest at floating rates by which the Interest Rate Basis or Interest Rate Bases will be multiplied to determine the applicable interest rate. The “Index Maturity” is the period to maturity of the instrument or obligation with respect to which the related Interest Rate Basis or Interest Rate Bases will be calculated.

          Interest rates that each trust offers on its floating rate notes may differ from the rates offered by other trusts depending upon, among other factors, the aggregate principal amount of notes purchased in any single transaction. Notes with different variable terms other than interest rates may also be offered by other trusts concurrently to different investors. Other trusts may change interest rates or formulas and other terms of notes from time to time, but no change of

terms will affect any note any other trust has previously issued or as to which any other trust has accepted an offer to purchase.

          Unless a series of notes that bears interest at floating rates is designated as a series of Floating Rate/ Fixed Rate Notes or a series of Inverse Floating Rate Notes, or as having an addendum attached or having other/additional provisions apply, in each case relating to a different interest rate formula, such series of notes that bears interest at floating rates will be a series of Regular Floating Rate Notes and will bear interest at the rate determined by reference to the applicable Interest Rate Basis or Interest Rate Bases:

          Commencing on the first Interest Reset Date, as specified in the relevant pricing supplement, the rate at which interest on a series of Regular Floating Rate Notes is payable will be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period, if any, from the date of issue to the first Interest Reset Date will be the Initial Interest Rate.

          If a series of notes that bears interest at floating rates is designated as a series of Floating Rate/ Fixed Rate Notes, such series of notes that bears interest at floating rates will bear interest at the rate determined by reference to the applicable Interest Rate Basis or Interest Rate Bases:

          Commencing on the first Interest Reset Date, the rate at which interest on a series of Floating Rate/ Fixed Rate Notes is payable will be reset as of each Interest Reset Date; provided, however, that:

          If a series of notes that bears interest at floating rates is designated as a series of Inverse Floating Rate Notes, such series of notes that bears interest at floating rates will bear interest at the Fixed Interest Rate minus the rate determined by reference to the applicable Interest Rate Basis or Interest Rate Bases:

provided, however, that interest on a series of Inverse Floating Rate Notes will not be less than zero. Commencing on the first Interest Reset Date, the rate at which interest on a series of Inverse Floating Rate Notes is payable will be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period, if any, from the date of issue to the first Interest Reset Date will be the Initial Interest Rate.

          The applicable pricing supplement will specify the dates on which the rate of interest on a series of notes that bears interest at floating rates will be reset (each, an “Interest Reset Date”), and the period between Interest Reset Dates will be the “Interest Reset Period.” Unless otherwise specified in the applicable pricing sup-

plement, the Interest Reset Dates will be, in the case of a series of notes that bears interest at floating rates which reset:

          If any Interest Reset Date for any series of notes that bears interest at floating rates would otherwise be a day that is not a business day, the particular Interest Reset Date will be postponed to the next succeeding business day, except that in the case of a series of notes that bears interest at floating rates as to which LIBOR is an applicable Interest Rate Basis and that business day falls in the next succeeding calendar month, the particular Interest Reset Date will be the immediately preceding business day.

          The interest rate applicable to a series of notes that bears interest at floating rates for an Interest Reset Period commencing on the related Interest Reset Date will be determined by reference to the applicable Interest Rate Basis as of the particular “Interest Determination Date,” which will be:

          The Interest Determination Date pertaining to a series of notes that bears interest at floating rates the interest rate of which is determined with reference to two or more Interest Rate Bases will be the latest business day which is at least two business days before the related Interest Reset Date for the applicable note that bears interest at floating rates on which each Interest Reset Basis is determinable.

          The indenture trustee will be the “Calculation Agent,” unless otherwise specified in the applicable pricing supplement. The interest rate applicable to each Interest Reset Period will be determined by the Calculation Agent on or prior to the Calculation Date (as defined below), except with respect to LIBOR, EURIBOR and the Eleventh District Cost of Funds Rate, which will be determined on the particular Interest Determination Date. Upon request of the registered holder of a series of notes that bears interest at floating rates, the Calculation Agent will disclose the interest rate then in effect and, if determined, the interest rate that will become effective as a result of a determination made for the next succeeding Interest Reset Date with respect to the particular series of notes that bears interest at floating rates. The “Calculation Date,” if applicable, pertaining to any Interest Determination Date will be the earlier of:

          A series of notes that bears interest at floating rates may also have either or both of the following if specified in the applicable pricing supplement:

          In addition to any Maximum Interest Rate that may apply to a series of notes that bears interest at floating rates, the interest rate on a series of notes that bears interest at floating rates will in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

          Unless otherwise specified in the applicable pricing supplement, interest on each series of notes that bears interest at floating rates will be payable on the date(s) set forth below (each, an “Interest Payment Date” with respect to such series of notes that bears interest at floating rates). Unless otherwise specified in the applicable pricing supplement, the Interest Payment Dates will be, in the case of a series of notes that bears interest at floating rates which reset:

          In addition, the maturity date will also be an Interest Payment Date.

          If any Interest Payment Date other than the maturity date for any series of notes that bears interest at floating rates would otherwise be a day that is not a business day, such Interest Payment Date will be postponed to the next succeeding business day, except that in the case of a series of notes that bears interest at floating rates as to which LIBOR is an applicable Interest Rate Basis and that business day falls in the next succeeding calendar month, the particular Interest Payment Date will be the immediately preceding business day. If the maturity date of a series of notes that bears interest at floating rates falls on a day that is not a business day, the trust will make the required payment of principal, premium, if any, and interest or other amounts on the next succeeding business day, and no additional interest will accrue in respect of the payment made on that next succeeding business day.

          All percentages resulting from any calculation on notes that bear interest at floating rates will be rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards. For example, 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655). All dollar amounts used in or resulting from any calculation on notes that bear interest at floating rates will be rounded, in the case of United States dollars, to the nearest cent or, in the case of a foreign currency, to the nearest unit (with one-half cent or unit being rounded upwards).

          With respect to each series of notes that bears interest at floating rates, accrued interest is calculated by multiplying the principal amount of such note that bears interest at floating rates by an accrued interest factor. The accrued interest factor is computed by adding the interest factor calculated for each day in the particular Interest Reset Period. The interest factor for each day will be computed by dividing the interest rate applicable to such day by 360, in the case of a series of notes that bears interest at floating rates as to which the CD Rate, the Commercial Paper Rate, the Eleventh District Cost of Funds Rate, the Federal Funds Open Rate, the Federal Funds Rate, LIBOR, EURIBOR or the Prime Rate is an applicable Interest Rate Basis, or by the actual number of days in the year, in the case of a series of notes that bears interest at floating rates as to which the CMT Rate or the Treasury Rate is an applicable Interest Rate Basis. In the case of a series of notes that bears interest at floating rates as to which the Constant Maturity Swap Rate is the Interest Rate Basis, the interest factor for each day will be computed by dividing the number of days in the interest period by 360 (the number of days to be calculated on the basis of a year of 360 days with twelve 30-day months (unless (i) the last day of the interest period is the 31st day of a month but the first day of the interest period is a day other than the 30th or 31st day of a month, in which case the month that includes that last day shall not be considered to be shortened to a 30-day month, or (ii) the last day of the interest period is the last day of the month of February, in which case the month of February shall not be considered to be lengthened to a 30-day month)). The interest factor for a series of notes that bears interest at floating rates as to which the interest rate is calculated with reference to two or more Interest Rate Bases will be calculated in each period in the same manner as if only the applicable Interest Rate Basis specified in the applicable pricing supplement applied.

          The Calculation Agent shall determine the rate derived from each Interest Rate Basis in accordance with the following provisions.

          “CD Rate” means:

          “H.15(519)” means the weekly statistical release designated as H.15(519), or any successor publication, published by the Board of Governors of the Federal Reserve System.

          “H.15 Daily Update” means the daily update of H.15(519), available through the world-wide-web site of the Board of Governors of the Federal Reserve System at http://www.federalreserve.gov/releases/ H15/update, or any successor site or publication.

          “CMT Rate” means:

          If two United States Treasury securities with an original maturity greater than the Index Maturity specified in the applicable pricing supplement have remaining terms to maturity equally close to the particular Index Maturity, the quotes for the United States Treasury security with the shorter original remaining term to maturity will be used.

          “Commercial Paper Rate” means:

Other/ Additional Provisions; Addendum

          Any provision with respect to a series of notes, including the specification and determination of one or more Interest Rate Bases, the calculation of the interest rate applicable to a note that bears interest at floating rates, the interest payment dates, the stated maturity date, any redemption or repayment provisions or any other term relating to the applicable notes, may be modified and/or supplemented as specified under “Other/ Additional Provisions” on the face thereof or in an addendum relating thereof, if so specified on the face thereof and in each case described in the applicable pricing supplement.

Discount Notes

          A trust may issue a series of notes (“Discount Notes”) that has an Issue Price (as specified in the applicable pricing supplement) that is less than the principal amount thereof by an amount that is equal to or greater than the de minimis amount. The de minimis amount is equal to 0.25% multiplied by the product of the principal amount of the notes and the number of full years to the stated maturity date. A series of Discount Notes may not bear any interest currently or may bear interest at a rate that is below market rates at the time of issuance. The difference between the Issue Price of a series of Discount Notes and par is referred to as the “Discount.” In the event of redemption, repayment or acceleration of maturity of a series of Discount Notes, the amount payable to the holders of such series of Discount Notes will be equal to the sum of:

          Unless otherwise specified in the applicable pricing supplement, for purposes of determining the amount of Discount that has accrued as of any date on which a redemption, repayment or acceleration of maturity occurs for a series of Discount Notes, a Discount will be accrued using a constant yield method. The constant yield will be calculated using a 30-day month, 360-day year convention, a compounding period that, except for the Initial Period (as defined below), corresponds to the shortest period between Interest Payment Dates for the applicable series of Discount Notes (with ratable accruals within a compounding period), a coupon rate equal to the initial coupon rate applicable to the applicable series of Discount Notes and an assumption that the maturity of such series of Discount Notes will not be accelerated. If the period from the date of issue to the first Interest Payment Date for a series of Discount Notes (the “Initial Period”) is shorter than the compounding period for such series of Discount Notes, a proportionate amount of the yield for an entire compounding period will be accrued. If the Initial Period is longer than the compounding period, then the period will be divided into a regular compounding period and a short period with the short period being treated as provided in the preceding sentence. The accrual of the applicable Discount may differ from the accrual of original issue discount for purposes of the Internal Revenue Code of 1986, as amended, certain series of Discount Notes may not be treated as having original issue discount within the meaning of such Code, and certain series of notes other than Discount Notes may be treated as issued with original issue discount for United States federal income tax purposes. See “Material United States Federal Income Tax Considerations.”

          Each trust may issue a series of notes which may be redeemed by the issuing trust when 20% or more of the original principal balance of such notes is outstanding, which are referred to as “callable” notes. In the case of discount notes that may be redeemed at a time when 20% or more of such notes are outstanding, such notes will be designated in their title as “callable” in the applicable pricing supplement. Unless otherwise specified in the applicable pricing supplement, such series of notes will otherwise be subject to the redemption provisions as specified under

“— Optional Redemption; Optional Repayment; No Sinking Fund.”

Amortizing Notes

          A trust may issue a series of notes (“Amortizing Notes”) with the amount of principal thereof and interest thereon payable in installments over their terms. Unless otherwise specified in the applicable pricing supplement, interest on each series of Amortizing Notes will be computed on the basis of a 360-day year of twelve 30-day months. Payments with respect to a series of Amortizing Notes will be applied first to interest due and payable thereon and then to the reduction of the unpaid principal amount thereof. Further information concerning additional terms and provisions of a particular series of Amortizing Notes will be specified in the applicable pricing supplement, including a table setting forth repayment information for such series of Amortizing Notes.

Book-Entry Notes

          We have established a depositary arrangement, on behalf of the trusts, with DTC with respect to the book-entry notes, the terms of which are summarized below.

          All book-entry notes having the same terms will be represented by one or more global securities. Each global security will be deposited with, or on behalf of, DTC and will be registered in the name of DTC or its nominee. No global security may be transferred or exchanged except as a whole by DTC or a nominee of DTC to DTC or to another nominee of DTC, or by DTC or another nominee of DTC to a successor of DTC or a nominee of a successor to DTC. So long as DTC or its nominee is the registered holder of a global security, DTC or its nominee will be the sole owner of the related book-entry notes represented thereby for all purposes under the indenture. Except as otherwise provided below, the beneficial owners of the global security or securities represented by book-entry notes will not be entitled to receive physical delivery of definitive notes and will not be considered the registered holders of the book-entry notes for any purpose under the indenture and no global security representing book-entry notes will be exchangeable or transferable. As a result, to exercise any rights of a registered holder under the indenture, a beneficial owner must rely on the procedures of DTC and, if the beneficial owner is not a participant, on the procedures of the participant or participants through which the beneficial owner owns its interest. The laws of some jurisdictions require that some purchasers of securities take physical delivery of securities in definitive form. These laws may limit the ability to transfer beneficial interests in a global security represented by book-entry notes.

          Each global security representing book-entry notes will be exchangeable for definitive notes having the same terms in a like aggregate principal amount only if:

          If any of these events occurs, the appropriate trust will print and deliver definitive notes. Definitive notes issued under these circumstances will be registered in the names of the beneficial owners of the related global securities as provided to the indenture trustee by the participants identified by DTC.

About the Depositary

          The following is based on information furnished by DTC:

          DTC will act as securities depository for the book-entry notes. The book-entry notes will be issued as fully registered securities in the name of Cede & Co. (DTC’s nominee) or another name requested by DTC. One fully registered global security will be issued for each issue of a series of

book-entry notes in the aggregate principal amount of that issue and will be deposited with, or on behalf of, DTC. If the aggregate principal amount of any issue exceeds DTC’s limit for a single global security, then the global securities will be issued in the form of one or more global securities having a principal amount equal to DTC’s limit and one or more additional global securities representing any remaining principal amount.

          DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. DTC holds securities that its direct participants deposit with it. DTC also facilitates the settlement among direct participants of transactions in deposited securities, such as transfers and pledges, through electronic computerized book-entry changes in direct participants’ accounts. This eliminates the need for physical movement of securities certificates. DTC’s direct participants include securities brokers and dealers (including the purchasing agent), banks, trust companies, clearing corporations and other organizations. DTC is owned by a number of its direct participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc. Access to DTC’s system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

          Under DTC’s system, purchases of book-entry notes must be made by or through direct participants, which will receive a credit for the book-entry notes on DTC’s records. The ownership interest of the actual purchaser is in turn recorded on the records of the direct and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through which they entered into the transaction. Transfers of ownership interests in book-entry notes are accomplished by entries made on the books of the direct and indirect participants acting on behalf of the beneficial owners. Beneficial owners will not receive definitive notes unless use of the book-entry system is discontinued as described above.

          To facilitate subsequent transfers, all global securities representing the book-entry notes deposited with, or on behalf of, DTC will be registered in the name of DTC’s nominee, Cede & Co., or any other name that DTC requests. The deposit of global securities with, or on behalf of, DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the book-entry notes; DTC’s records reflect only the identity of the direct participants to whose accounts the book-entry notes are credited, which may or may not be the beneficial owners. DTC’s participants are responsible for keeping account of their holdings on behalf of their customers.

          Conveyance of notices and other communications from DTC to direct participants, from direct participants to indirect participants and from direct participants and indirect participants to beneficial owners are governed by arrangements among them and are subject to statutory and regulatory requirements.

          Neither DTC nor Cede & Co. will consent or vote with respect to global securities. Under its usual procedures, DTC mails an omnibus proxy to a company as soon as possible after a record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the book-entry notes are credited on the record date (identified in a listing attached to the omnibus proxy).

          The trust will make payments on the global securities in immediately available funds to Cede & Co. or any other nominee named by DTC. DTC’s practice is to credit direct participants’ accounts on the applicable payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payment on that date. Payments by participants to beneficial owners are governed by standing instructions and customary practices and are subject to statutory

and regulatory requirements. The trust and the trustee are responsible only for making payments to DTC; DTC is responsible for disbursing those payments to its direct participants and the direct participants (and any indirect participants) are solely responsible for disbursing those payments to the beneficial owners.

          Any redemption notices will be sent to Cede & Co. If less than all of the book-entry notes having the same terms are being redeemed, DTC’s current practice is to determine by lot the amount of the interest of each direct participant in those notes to be redeemed.

          A beneficial owner must give notice of any election to have its book-entry notes repaid through its participant to the indenture trustee. Delivery of the book-entry notes will be effected by causing the relevant direct participant to transfer the relevant part of its interest in the global securities to the indenture trustee on DTC’s records.

          DTC may discontinue providing its services as securities depository at any time by giving reasonable notice to us or the indenture trustee. If we do not obtain a successor securities depository, the applicable trust will print and deliver definitive notes.

          We may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). If we do so, the applicable trust will print and deliver definitive notes.

SPECIAL PROVISIONS RELATING TO FOREIGN CURRENCY NOTES

General

          Unless otherwise specified in the applicable pricing supplement, foreign currency notes will not be sold in, or to residents of, the country issuing the specified currency. The information set forth in this prospectus supplement is directed to prospective purchasers who are United States residents and, with respect to foreign currency notes, is by necessity incomplete. We, PFG, the trusts and the Agents disclaim any responsibility to advise prospective purchasers who are residents of countries other than the United States with respect to any matters that may affect the purchase, holding or receipt of payments of principal of, and premium, if any, and interest, if any, on, their foreign currency notes. These purchasers should consult their own financial and legal advisors with regard to these risks. See “Risk Factors — Risk Factors Relating to the Notes — If the trust issues notes denominated in a foreign currency, those notes are subject to exchange rate and exchange control risks” in the accompanying prospectus.

Payment of Principal, Premium, if Any, and Interest, if Any

          Unless otherwise specified in the applicable pricing supplement, a trust is obligated to make payments of principal of, and premium, if any, and interest, if any, on, a foreign currency note in the specified currency. Any amounts so payable by the trust in the specified currency will be converted by the exchange rate agent named in the applicable pricing supplement (the “exchange rate agent”) into United States dollars for payment to the registered holders thereof unless otherwise specified in the applicable pricing supplement or a registered holder elects, in the manner described below, to receive these amounts in the specified currency.

          Any United States dollar amount to be received by a registered holder of a foreign currency note will be based on the highest bid quotation in The City of New York received by the exchange rate agent at approximately 11:00 A.M., New York City time, on the second business day preceding the applicable payment date from three recognized foreign exchange dealers (one of whom may be the exchange rate agent) selected by the exchange rate agent and approved by the trust for the purchase by the quoting dealer of the specified currency for United States dollars for settlement on that payment date in the aggregate amount of the specified currency payable to all registered holders of foreign currency notes scheduled to receive United States dollar payments and at which the applicable dealer commits to execute a contract. All currency exchange costs will be borne by the registered holders of foreign currency notes by deductions from any payments. If three bid quotations are not

available, payments will be made in the specified currency.

          Registered holders of foreign currency notes may elect to receive all or a specified portion of any payment of principal, premium, if any, and/or interest, if any, in the specified currency by submitting a written request to the indenture trustee at its corporate trust office in The City of New York on or prior to the applicable regular record date or at least 15 calendar days prior to the maturity date, as the case may be. This written request may be mailed or hand delivered or sent by cable, telex or other form of facsimile transmission. This election will remain in effect until revoked by written notice delivered to the indenture trustee on or prior to a regular record date or at least 15 calendar days prior to the maturity date, as the case may be. Registered holders of foreign currency notes to be held in the name of a broker or nominee should contact their broker or nominee to determine whether and how an election to receive payments in the specified currency may be made.

          Unless otherwise specified in the applicable pricing supplement, if the specified currency is other than United States dollars, a beneficial owner of a global security which elects to receive payments of principal, premium, if any, and/or interest, if any, in the specified currency must notify the participant through which it owns its interest on or prior to the applicable record date or at least 15 calendar days prior to the maturity date, as the case may be, of its election. The applicable participant must notify the depositary of its election on or prior to the third business day after the applicable record date or at least 12 calendar days prior to the maturity date, as the case may be, and the depositary will notify the indenture trustee of that election on or prior to the fifth business day after the applicable record date or at least ten calendar days prior the maturity date, as the case may be. If complete instructions are received by the participant from the applicable beneficial owner and forwarded by the participant to the depositary, and by the depositary to the trustee, on or prior to such dates, then the applicable beneficial owner will receive payments in the specified currency.

          A trust will make payments of the principal of, and premium, if any, and/or interest, if any, on foreign currency notes which are to be made in United States dollars in the manner specified herein with respect to notes denominated in United States dollars. See “Description of the Notes — General.” A trust will make payments of interest, if any, on foreign currency notes which are to be made in the specified currency on an Interest Payment Date other than the maturity date by check mailed to the address of the registered holders of their foreign currency notes as they appear in the register, subject to the right to receive these payments by wire transfer of immediately available funds under the circumstances described under “Description of the Notes — General.” A trust will make payments of principal of, and premium, if any, and/or interest, if any, on, foreign currency notes which are to be made in the specified currency on the maturity date by wire transfer of immediately available funds to an account with a bank designed at least 15 calendar days prior to the maturity date by the applicable registered holder, provided the particular bank has appropriate facilities to make these payments and the particular foreign currency note is presented and surrendered at the office or agency maintained by the trust for this purpose in the Borough of Manhattan, The City of New York, in time for the indenture trustee, acting in its capacity as servicer, to make these payments in accordance with its normal procedures.

Availability of Specified Currency

          If the specified currency for foreign currency notes is not available for any required payment of principal, premium, if any, and/or interest, if any, due to the imposition of exchange controls or other circumstances beyond its control, a trust will be entitled to satisfy its obligations to the registered holders of these foreign currency notes by making payments in United States dollars on the basis of the market exchange rate, computed by the exchange rate agent, on the second business day prior to the particular payment or, if the market exchange rate is not then available, on the basis of the most recently available market exchange rate.

          The “market exchange rate” for a specified currency other than United States dollars means the noon dollar buying rate in The City of New York for cable transfers for the specified currency as certified for customs purposes (or, if not so certified, as otherwise determined) by the Federal Reserve Bank of New York.

          All determinations made by the exchange rate agent shall be at its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and binding on the registered holders of the foreign currency notes.

Judgments

          Under current New York law, a state court in the State of New York would be required to render a judgment in respect of a foreign currency note in the specified currency, and a judgment in the specified currency would be converted into United States dollars at the exchange rate prevailing on the date of entry of the judgment. Accordingly, registered holders of foreign currency notes would be subject to exchange rate fluctuations between the date of entry of a foreign currency judgment and the time when the amount of the foreign currency judgment is paid in United States dollars and converted by the applicable registered holder into the specified currency. It is not certain, however, whether a non-New York state court would follow the same rules and procedures with respect to conversions of foreign currency judgments.

          Each trust will indemnify the registered holder of any of its notes against any loss incurred as a result of any judgment or order being given or made for any amount due under the particular note and that judgment or order requiring payment in a currency (the “judgment currency”) other than the specified currency, and as a result of any variation between:

DESCRIPTION OF THE FUNDING AGREEMENTS

          Each trust will use the net proceeds from the issuance of a series of notes to the public and the issuance of the trust beneficial interest to the trust beneficial owner to purchase a funding agreement. The funding agreement will have substantially similar payment and other terms to the related series of notes. The funding agreement may be interest bearing or non-interest bearing. A funding agreement may bear interest at either a fixed or a floating rate, or a combination of fixed and floating rates, as specified in the applicable pricing supplement. The calculation of the interest rate, the dates of interest and maturity payments and such other payment terms on the funding agreement will be determined in the same manner as described above under “Description of the Notes.” An amount equal to the funding agreement deposit plus accrued but unpaid interest, if any, and accrued discount, if any (in the case of a discount funding agreement) (other than an amortizing funding agreement) will be payable on its stated maturity date, as specified in the applicable pricing supplement. We may issue an amortizing funding agreement that pays an amount in respect of both interest and deposit amount over the life of the funding agreement, if specified in the applicable pricing supplement.

          The pricing supplement relating to a series of notes will describe the following pricing terms of the related funding agreement:

          For a more detailed discussion of the funding agreements, see “Description of the Funding Agreements” in the accompanying prospectus.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

          The following is a general discussion of the material United States federal income tax considerations relating to the purchase, ownership and disposition of the notes by initial purchasers of the notes who purchase the notes at their issue price (determined as set forth below) and hold the notes as capital assets within the meaning of section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). The statements set forth in the following discussion, to the extent they constitute matters of United States federal income tax law or legal conclusions with respect thereto, represent the opinion of Sidley Austin LLP, special United States income tax counsel to us. This discussion does not address all of the tax considerations that may be relevant to prospective purchasers in light of their particular circumstances or to persons subject to special rules under United States federal tax laws, such as certain financial institutions, insurance companies, real estate investment trusts, dealers in securities, tax-exempt entities, certain former citizens or residents of the United States, persons who hold the notes as part of a “straddle,” “hedging,” “conversion” or other integrated transaction, persons who mark their securities to market for United States federal income tax purposes or persons whose functional currency (as defined in section 985 of the Code) is not the U.S. dollar. In addition, this discussion does not address the effect of any state, local or foreign tax laws or the effect of the U.S. federal alternative minimum tax. Accordingly, prospective purchasers are advised to consult their own tax advisers with respect to their individual circumstances.

          This discussion is based on the Code, the Treasury Regulations promulgated thereunder and administrative and judicial pronouncements, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect.

          For purposes of the following discussion, the term “U.S. Holder” means a beneficial owner of a note who or which is, for United States federal income tax purposes, (i) an individual citizen or resident of the United States, (ii) a corporation created or organized in or under the laws of the United States or of any political subdivision thereof or (iii) an estate or trust treated as a United States person under section 7701(a)(30) of the Code. The term “Non-U.S. Holder” means a beneficial owner of a note other than a U.S. Holder. For the purposes of this discussion, U.S. Holders and Non-U.S. Holders shall be referred to collectively as “holders.”

          Special rules, not discussed in this prospectus supplement or the accompanying prospectus, may apply to persons purchasing notes through entities treated for U.S. federal income tax purposes as partnerships, and such persons should consult their own tax advisors in that regard.

Classification of the Notes and the Trust

          We intend to take the position, for United States federal income tax purposes, that each trust will be disregarded and that the notes will be treated as representing our indebtedness (the “Intended Tax Characterization”). Each holder of a note (or any beneficial interest therein), by acceptance of the note (or beneficial interest), agrees to treat the trust with respect to which the note was issued and the note consistently with the Intended Tax Characterization.

          Notwithstanding the Intended Tax Characterization, it is possible that a trust could be viewed as a separate entity for United States federal income tax purposes. Sidley Austin LLP is of the opinion that, under current law and assuming full compliance with the terms of the trust agreement and the indenture (and certain other documents), and based on certain facts and assumptions contained in such opinion, each trust will not be classified as an association (or publicly traded partnership) taxable as a corporation for United States federal income tax purposes. Accordingly, whether the Intended Tax Characterization is respected or not, each trust will not be treated as a taxable entity for United States federal income tax purposes. If a trust is viewed as a separate entity rather than disregarded, each holder of a note (or any beneficial interest therein) agrees to treat the trust as a grantor trust and the notes as undivided ownership interests in such trust. If this were the case, a U.S. Holder would be required to include in income, consistent with its method of accounting, its pro rata share of any amounts paid to the relevant trust to satisfy expenses and would be entitled to deduct, consistent with its method of accounting, its pro rata share of any such expenses as provided in sections 162 and 212 of the Code. If the U.S. Holder is an individual, trust or estate, or to the extent the U.S. Holder’s income is reportable on the income tax return of an individual, trust or estate, the deduction for such person’s share of such expenses will be allowed only to the extent that all of such person’s miscellaneous itemized deductions, including such person’s share of the relevant trust’s expenses, exceed two percent of such person’s adjusted gross income. In addition, an individual’s itemized deductions may be subject to other limitations. Accordingly, U.S. Holders who are individuals, or whose income is reported in whole or in part on the income tax return of a United States citizen or resident, should consult their tax advisers with respect to such deductions.

          The remainder of this summary assumes that the Intended Tax Characterization is correct.

U.S. Holders

          Each U.S. Holder of a note will include in income payments of “qualified stated interest” (as described below) in respect of such note, in accordance with such U.S. Holder’s method of accounting for United States federal income tax purposes, as ordinary interest income. In general, if the issue price of a note, determined by the first price at which a substantial amount of the notes of the related series are sold (ignoring sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), is less than the “stated redemption price at maturity” (as described below) of such note by an amount equal to or more than a de minimis amount, a

U.S. Holder will be considered to have purchased such note with original issue discount (“OID”). In general, the de minimis amount is equal to ¹/4 of one percent of the stated redemption price at maturity multiplied by the weighted average number of complete years to maturity from the issue date of such note. If a U.S. Holder acquires a note with OID, then regardless of such U.S. Holder’s method of accounting, such U.S. Holder will be required to accrue its pro rata share of OID on such note on a constant-yield basis and include such accruals in gross income, whether or not such U.S. Holder has received any cash payment on the notes. Any amount not treated as OID because it is less than the de minimis amount generally must be included in income (generally as gain from the sale of notes) as principal payments are received in the proportion that each such payment bears to the original principal amount of the note. Special rules apply to notes with a fixed maturity of one year or less. See “— Short Term Notes.”

          “Stated redemption price at maturity” means the sum of all payments to be made on a note other than payments of “qualified stated interest.” “Qualified stated interest” generally means stated interest that is unconditionally payable at least annually at a single fixed rate or, in the case of a variable rate debt instrument (as defined below), at a single qualified floating rate or single objective rate (as such terms are defined below). If a note is a variable rate debt instrument but interest is payable at other than a single qualified floating rate or a single objective rate, special rules apply that are not discussed in this prospectus supplement or the accompanying prospectus.

          In the case of a variable rate debt instrument, the amount of qualified stated interest and the amount of OID, if any, that accrues during an accrual period is generally determined assuming that the variable rate is a fixed rate equal to (i) in the case of a qualified floating rate or qualified inverse floating rate (each as defined below), the value, as of the issue date, of the qualified floating rate or qualified inverse floating rate or (ii) in the case of an objective rate (as defined below, and other than a qualified inverse floating rate), a fixed rate that reflects the yield that is reasonably expected for the debt instrument, and the qualified stated interest (or, if there is no qualified stated interest, OID) allocable to an accrual period is increased (or decreased) if the interest actually paid during an accrual period exceeds (or is less than) the interest assumed to be paid during the accrual period pursuant to clause (i) or (ii), as applicable. Special rules apply to a variable rate debt instrument that provides for stated interest at a fixed rate under certain circumstances.

          A “variable rate debt instrument” is a debt instrument that (i) has an issue price that does not exceed the total noncontingent principal payments by more than an amount equal to the lesser of (a) 0.015 multiplied by the product of such total noncontingent principal payments and the number of complete years to maturity of the instrument (or, in the case of a note providing for the payment of any amount other than qualified stated interest prior to maturity, multiplied by the weighted average maturity of the note) or (b) 15 percent of the total noncontingent principal payments, (ii) provides for stated interest (compounded or paid at least annually) at the current value of (A) one or more qualified floating rates, (B) a single fixed rate and one or more qualified floating rates, (C) a single objective rate or (D) a single fixed rate and a single objective rate that is a qualified inverse floating rate, and (iii) does not provide for any principal payments that are contingent. The current value is the value of the rate on any day that is no earlier than three months prior to the first day on which that value is in effect and no later than one year following that first day.

          A “qualified floating rate” is generally a floating rate under which variations in the rate can reasonably be expected to measure contemporaneous variations in the cost of newly borrowed funds in the currency in which a debt instrument is denominated. A multiple of a qualified floating rate is not a qualified floating rate unless the relevant multiplier is (i) fixed at a number that is greater than 0.65 but not more than 1.35 or (ii) fixed at a number that is greater than 0.65 but not more than 1.35, increased or decreased by a fixed rate. A variable rate is not considered a qualified floating rate if the variable rate is subject to a cap, floor, governor (i.e., a restriction on the amount of increase or decrease in the stated interest rate) or similar restriction that is reasonably expected as of the issue date to cause the yield on the note to be significantly more or less than the expected yield determined without the restriction (other than a cap, floor, governor or

similar restriction that is fixed throughout the term of the note).

          An “objective rate” is a rate (other than a qualified floating rate) that is determined using a single fixed formula and that is based on objective financial or economic information, provided, however, that an objective rate will not include a rate based on information that is within the control of the issuer (or certain related parties of the issuer) or that is unique to the circumstances of the issuer (or certain related parties of the issuer), such as dividends, profits or the value of the issuer’s stock. A “qualified inverse floating rate” is an objective rate (x) that is equal to a fixed rate minus a qualified floating rate and (y) the variations in which can reasonably be expected to inversely reflect contemporaneous variations in the qualified floating rate (disregarding any caps, floors, governors or similar restrictions that would not, as described above, cause a rate to fail to be a qualified floating rate). Notwithstanding the first sentence of this paragraph, a rate is not an objective rate if it is reasonably expected that the average value of the rate during the first half of the note’s term will be either significantly less than or significantly greater than the average value of the rate during the final half of the note’s term. The Internal Revenue Service (“IRS”) may designate rates other than those specified above that will be treated as objective rates. As of the date of this prospectus supplement, no other rates have been designated.

          If interest on a note is stated at a fixed rate for an initial period of one year or less followed by a variable rate that is either a qualified floating rate or an objective rate for a subsequent period, and the value of the variable rate on the issue date is intended to approximate the fixed rate, the fixed rate and the variable rate together constitute a single qualified floating rate or objective rate. A fixed rate and a variable rate will be conclusively presumed to meet the requirements of the preceding sentence if the value of the variable rate on the issue date does not differ from the value of the fixed rate by more than 0.25 percentage points (25 basis points).

          If a floating rate note does not qualify as a variable rate debt instrument or otherwise provides for contingent payments, or if a fixed rate note provides for contingent payments, such note may constitute a “contingent payment debt instrument.” A note that is a contingent payment debt instrument is generally taxable as follows:

          First, we are required to determine, as of the issue date, the comparable yield for the note. The comparable yield is generally the yield at which we would issue a fixed rate debt instrument with terms and conditions similar to those of the note (including the level of subordination, term, timing of payments and general market conditions, but not taking into consideration the riskiness of the contingencies or the liquidity of the note), but not less than the applicable federal rate announced monthly by the IRS (the “AFR”). In certain cases where a floating rate note is marketed or sold in substantial part to tax-exempt investors or other investors for whom the prescribed inclusion of interest is not expected to have a substantial effect on their U.S. federal tax liability, the comparable yield for the note, without proper evidence to the contrary, is presumed to be the AFR.

          Second, we are required to construct a projected schedule of payments (the “Schedule”). The Schedule is determined as of the issue date and generally remains in place throughout the term of the note. The Schedule includes each noncontingent payment and a projected payment for each contingent payment. The Schedule must produce the comparable yield determined as set forth above.

          Third, under the usual rules applicable to OID and based on the comparable yield, each U.S. Holder will be required to accrue its pro rata share of OID on a constant yield basis and include such accrual in gross income.

          Fourth, appropriate adjustments are made to the OID determined under the foregoing rules to account for any differences between actual contingent payments and the projected payments on the Schedule.

          Differences between the actual contingent payments made to a U.S. Holder in such U.S. Holder’s taxable year and the projected payments for such taxable year are generally aggregated and taken into account, in the case of a positive difference, as additional interest income, or, in the case of a negative difference, first as a reduction in OID for such year and thereafter, subject to certain limitations, as ordinary loss. We

are required to provide to each holder of notes a copy of the Schedule. Our determination of the Schedule must be used by a U.S. Holder unless the Schedule is unreasonable and such U.S. Holder discloses to the IRS that it is using a different schedule. In general, any gain realized by a U.S. Holder on the sale, exchange, retirement or other disposition of a note that is a contingent payment debt instrument prior to the time no contingent payments remain is treated as interest income. In general, any loss on such a note is treated as ordinary loss to the extent it does not exceed such U.S. Holder’s prior interest inclusions on the note (net of negative adjustments). The above described treatment of contingent payment debt instruments assumes that the instrument is properly treated as debt for U.S. federal tax purposes.

          If the amount paid by a U.S. Holder for a note exceeds the stated redemption price at maturity of the note, the U.S. Holder generally will be considered to have purchased the note at a premium equal in amount to such excess. In this event, the U.S. Holder may elect to amortize such premium, generally on a constant-yield basis, as an offset to interest income. In the case of a note that may be redeemed prior to maturity, the premium is calculated assuming the trust and the U.S. Holder will exercise or not exercise redemption rights in a manner that maximizes the U.S. Holder’s yield. It is unclear how premium is calculated when the redemption date or the amount of any redemption premium is uncertain. The election to amortize bond premium, once made, will apply to all debt obligations held or subsequently acquired by the electing U.S. Holder on or after the first day of the first taxable year to which the election applies, and may not be revoked without the consent of the IRS.

          Notes that have a fixed maturity of one year or less (“Short-Term Notes”) will be treated as issued with OID. In general, an individual or other U.S. Holder that uses the cash method of accounting is not required to accrue such OID unless the U.S. Holder elects to do so. If such an election is not made, any gain recognized by such U.S. Holder on the sale, exchange, retirement or other disposition of Short-Term Notes will be ordinary income to the extent of the OID accrued on a straight-line basis, or upon election under the constant yield method (based on daily compounding), through the date of sale, exchange, retirement or other disposition, and a portion of the deduction otherwise allowable to such U.S. Holder for interest on borrowings allocable to Short-Term Notes will be deferred until a corresponding amount of income is realized. U.S. Holders who report income for United States federal income tax purposes under the accrual method of accounting and certain other holders are required to accrue OID related to a Short-Term Note as ordinary income on a straight-line basis unless an election is made to accrue the OID under a constant yield method (based on daily compounding).

          In general, a U.S. Holder of a note will have a tax basis in the note equal to the cost of the note to the U.S. Holder, increased by any amount includible in income by the U.S. Holder as OID and reduced by any amortized premium and any payments other than payments of qualified stated interest. Upon a sale, exchange, retirement or other disposition of a note, a U.S. Holder will generally recognize gain or loss equal to the difference between the amount realized on the sale, exchange, retirement or other disposition (less any amount realized that is attributable to accrued but unpaid qualified stated interest, which will constitute ordinary income if not previously included in income) and the U.S. Holder’s tax basis in such note. Subject to the rules described below under “Foreign Currency Notes,” such gain or loss will be long-term capital gain or loss if the U.S. Holder held the note for more than one year at the time of disposition. A U.S. Holder that is an individual is entitled to preferential treatment for net long-term capital gains. The ability of a U.S. Holder to offset capital losses against ordinary income is limited.

          The following discussion generally describes special rules that apply, in addition to the rules described above, to notes that are denominated in, or provide for payments determined by reference to, a currency or currency unit other than the U.S. dollar (“Foreign Currency Notes”).

The amount of qualified stated interest paid with respect to a Foreign Currency Note that is includible in income by a U.S. Holder that uses the cash method of accounting for United States federal income tax purposes is the U.S. dollar value of the amount paid, as determined on the date of actual or constructive receipt by such U.S. Holder, using the spot rate of exchange on such date. In the case of qualified stated interest paid to a U.S. Holder that uses the accrual method of accounting, and in the case of OID (other than OID from a Short-Term Note that is not required to be accrued) for every U.S. Holder, such U.S. Holder is required to include the U.S. dollar value of the amount of such interest income or OID that accrued during the accrual period. The U.S. dollar value of such accrued interest income or OID is generally determined by translating such income at the average rate of exchange for the accrual period or, at the U.S. Holder’s election, at the spot rate of exchange on the last day of the accrual period. The U.S. Holder will recognize, as ordinary income or loss, foreign currency exchange gain or loss with respect to such accrued interest income or OID on the date the interest or OID is actually or constructively received, reflecting fluctuations in currency exchange rates between the exchange rate used to determine the accrued interest income or OID for the relevant accrual period and the exchange rate on the date such interest or OID is actually or constructively received.

          The amount realized with respect to a sale, exchange, retirement or other disposition of a Foreign Currency Note generally will be the U.S. dollar value of the payment received, determined on the date of disposition of such note (using the spot rate on such date). Gain or loss that is recognized will be ordinary income or loss to the extent it is attributable to fluctuations in currency rates between the date of purchase and the date of sale, exchange, retirement or other disposition. Such foreign currency gain or loss will be recognized only to the extent of the total gain or loss realized by the U.S. Holder on the sale, exchange, retirement or other disposition of the Foreign Currency Note. Any gain or loss realized by a U.S. Holder in excess of such foreign currency gain or loss generally will be capital gain or loss.

Non-U.S. Holders

          Subject to the discussion below concerning backup withholding, the following is a discussion of United States federal income tax considerations generally applicable to Non-U.S. Holders:

          Sections 871(h) and 881(c) of the Code require that, in order to obtain the exemption from withholding of United States federal income tax described in paragraph (a) above, either the Non-U.S. Holder or a securities clearing organiza-

tion, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business (a “Financial Institution”) and that is holding the note on behalf of such Non-U.S. Holder must file a statement with the withholding agent to the effect that the Non-U.S. Holder is not a United States person. Such requirement will be fulfilled if the Non-U.S. Holder certifies on IRS Form W-8BEN (or successor form), under penalties of perjury, that it is not a United States person and provides its name and address, or any Financial Institution holding the note on behalf of the Non-U.S. Holder files a statement with the withholding agent to the effect that it has received such a statement from the Non-U.S. Holder (and furnishes the withholding agent with a copy thereof). In addition, in the case of notes held by a foreign intermediary (other than a “qualified intermediary”) or a foreign partnership (other than a “withholding foreign partnership”), the foreign intermediary or partnership, as the case may be, generally must provide a properly executed IRS Form W-8IMY (or successor form) and attach thereto an appropriate certification by each foreign beneficial owner or United States payee.

          If a Non-U.S. Holder is engaged in a trade or business in the United States, and if amounts treated as interest for United States federal income tax purposes on a note or gain realized on the sale, exchange, retirement or other disposition of a note is effectively connected with the conduct of such trade or business, the Non-U.S. Holder, although exempt from the withholding of federal income tax described in paragraph (a) above, will, unless otherwise provided by an applicable tax treaty, generally be subject to regular United States federal income tax on such effectively connected income in the same manner as if it were a U.S. Holder. In lieu of the certificate described in the preceding paragraph, such Non-U.S. Holder will be required to provide a properly executed IRS Form W-8ECI (or successor form) to the withholding agent in order to claim an exemption from withholding tax. In addition, if such Non-U.S. Holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

          If a Non-U.S. Holder is not eligible for relief under one of the exceptions described above, it may nonetheless qualify for an exemption from, or reduced rate of, United States withholding tax under an income tax treaty. In general, this exemption or reduced rate of tax applies only if the Non-U.S. Holder provides a properly completed IRS Form W-8BEN claiming benefits under an applicable treaty.

Backup Withholding and Information Reporting

          Backup withholding and information reporting requirements generally apply to interest (including OID) and principal payments made to, and to the proceeds of sales by, certain non-corporate U.S. Holders. A U.S. Holder not otherwise exempt from backup withholding generally can avoid backup withholding by providing a properly-executed IRS Form W-9 (or successor form). In the case of a Non-U.S. Holder, backup withholding and information reporting will not apply to payments on, or from the sale, exchange, retirement or other disposition of, a note if a statement referred to in clause (a)(v) of the first paragraph in “Non-U.S. Holders” above has been received and the payor does not have actual knowledge that the beneficial owner is a United States person. Withholding agents must nevertheless report to the IRS and to each Non-U.S. Holder the amount of interest (including OID) paid with respect to the notes held by each Non-U.S. Holder and the rate of withholding (if any) applicable to each Non-U.S. Holder. Non-U.S. Holders should consult their own tax advisers regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedure for obtaining such an exemption, if available. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against the beneficial owner’s United States federal income tax liability provided the required information is furnished to the IRS.

European Union Directive on the Taxation of Savings Income

          On July 1, 2005, a directive adopted by the European Council of Economics and Finance

Ministers regarding the taxation of savings income took effect. Should any deduction or withholding on account of tax be required to be made, or be made, in accordance with the terms of this section, no additional amounts shall be paid or payable by any trust or by us unless specified in the applicable pricing supplement or funding agreement that additional amounts will be paid. See “Description of the Notes — Final European Union Withholding Tax System.”

Opinion Regarding Tax Matters

          Prior to the issuance of any notes, we will file with a Current Report on Form 8-K an unqualified opinion of legal counsel regarding the tax treatment of such notes.

PLAN OF DISTRIBUTION

          This prospectus supplement relates to the offering of notes by separate trusts from time to time for sale to or through Merrill Lynch, Pierce, Fenner & Smith Incorporated, ABN AMRO Incorporated, Banc of America Securities LLC, Barclays Capital Inc., Bear, Stearns & Co. Inc., BNP Paribas Securities Corp., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman, Sachs & Co., J.P. Morgan Securities Inc., Lehman Brothers Inc., Morgan Stanley & Co. Incorporated, UBS Securities LLC and Wachovia Capital Markets, LLC (the “Agents”) pursuant to a distribution agreement (the “Distribution Agreement”) among the applicable trust, us, PFG and the Agents. From time to time, we may also appoint one or more other broker-dealers to act as an Agent under the secured medium-term notes program pursuant to the terms of the Distribution Agreement and such Agent will be specified in the applicable pricing supplement. The Agents, individually or in a syndicate, may purchase notes, as principal, from separate trusts from time to time for resale to investors and other purchasers at varying prices relating to prevailing market prices at the time of resale as determined by the applicable Agent or, if so specified in the applicable pricing supplement, for resale at a fixed offering price. However, the applicable trust may agree with an Agent for that Agent to utilize its reasonable efforts on an agency basis on its behalf to solicit offers to purchase notes at 100% of the principal amount thereof, unless otherwise specified in the applicable pricing supplement. In all such cases, a single trust may only issue notes of a single series on the initial date of sale of such notes. No additional notes may thereafter be issued by that trust. Unless otherwise specified in the applicable pricing supplement, the applicable trust will pay a commission to an Agent, ranging from .150% to .875% of the principal amount of each note, depending upon its stated maturity, sold through that Agent as its agent. The notes may be sold to United States and foreign institutional and other investors.

          Subject to the terms of the Distribution Agreement, concurrently with any offering of notes as described in this prospectus supplement by the applicable trust, a separate trust may issue other notes under our Principal^® Life CoreNotes^® program or our secured medium-term notes retail program primarily to retail investors or the accompanying prospectus or this prospectus supplement.

          Unless otherwise specified in the applicable pricing supplement, any note sold to an Agent as principal will be purchased by that Agent at a price equal to 100% of the principal amount thereof less a percentage of the principal amount equal to the commission applicable to an agency sale of a note of identical maturity. An Agent may sell notes it has purchased from the applicable trust as principal to certain dealers less a concession equal to all or any portion of the discount received in connection with that purchase. An Agent may allow, and dealers may reallow, a discount to certain other dealers. After the initial offering of notes (in the case of notes to be sold on a fixed offering price basis), the concession and the reallowance may be changed.

          The applicable trust reserves the right to withdraw, cancel or modify the offer made hereby without notice and may reject offers in whole or in part. Each Agent will have the right, in its discretion reasonably exercised, to reject in whole or in part any offer to purchase notes received by it on an agency basis.

          Unless otherwise specified in the applicable pricing supplement, you will be required to

pay the purchase price of your notes in immediately available funds in the specified currency in The City of New York on the date of settlement.

          Upon issuance, the notes will not have an established trading market. The notes may not be listed on any securities exchange. The Agents may from time to time purchase and sell notes in the secondary market, but the Agents are not obligated to do so. There can be no assurance that a secondary market for the notes will develop or that there will be liquidity in the secondary market if one develops. From time to time, the Agents may make a market in the notes, but the Agents are not obligated to do so and may discontinue any market-making activity at any time.

          In connection with an offering of notes purchased by one or more Agents as principal on a fixed offering price basis, the applicable Agents will be permitted to engage in certain transactions that stabilize the price of notes. These transactions may consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of notes. If those Agents create a short position in notes (i.e., if they sell notes in an amount exceeding the amount referred to in the applicable pricing supplement), they may reduce that short position by purchasing notes in the open market. In general, purchases of notes for the purpose of stabilization or to reduce a short position could cause the price of notes to be higher than it might be in the absence of these type of purchases.

          None of us, PFG, the applicable trust or any Agent makes any representation or prediction as to the direction or magnitude of any effect that the transactions described in the immediately preceding paragraph may have on the price of notes. In addition, none of us, PFG, the applicable trust or any Agent makes any representation that the Agents will engage in any such transactions or that such transactions, once commenced, will not be discontinued without notice.

          The Agents are “underwriters” within the meaning of the Securities Act of 1933, as amended, with respect to the notes being distributed, the funding agreement purchased by the trust and the guarantee issued to the trust. We and PFG have agreed, jointly and severally, to indemnify the Agents against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the Agents may be required to make in respect thereof.

          With respect to any series of notes as to which affiliates of the indenture trustee will serve as an Agent, the relevant trust will appoint an eligible and unaffiliated entity to serve as indenture trustee with respect to such series of notes, instead of the indenture trustee.

          We are a statutory issuer of the notes under the Securities Act of 1933, as amended. In addition, under the Securities Act of 1933, as amended, each trust is a statutory underwriter of the related funding agreement and guarantee.

          In the ordinary course of business, the Agents and their affiliates have engaged, and may in the future engage, in investment and commercial banking transactions with us and certain of our affiliates, including PFG.

ABOUT THIS PROSPECTUS

          This prospectus is part of a registration statement that we and PFG filed with the Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process. Under this process, notes may be offered, from time to time, through newly established separate and distinct trusts, up to a total amount of $5,000,000,000 in aggregate principal amount or the equivalent principal amount in one or more foreign or composite currencies. This prospectus provides you with a general description of the notes offered through trusts and the underlying funding agreements and guarantees. An accompanying prospectus supplement to this prospectus will provide the specific terms of the notes and the underlying funding agreements and guarantees. Each time notes are offered through a trust, we may also provide a pricing supplement to this prospectus and the applicable prospectus supplement that will contain specific information about the terms of the offering. The pricing supplement may also add to, update, supplement or clarify the information contained in this prospectus and applicable prospectus supplement and, accordingly, before you agree to purchase any notes, you should read this prospectus, the applicable prospectus supplement and any pricing supplement together with the information described under the heading “Where You Can Find More Information” on page 11.

          In this prospectus, references to “Principal Life,” “we,” “us” and “our” are to Principal Life Insurance Company, an Iowa insurance company, references to “PFG” are to Principal Financial Group, Inc., a Delaware corporation and our indirect parent company, and references to a “trust” are to the applicable separate and distinct special purpose common law trusts, formed in a jurisdiction located in the United States of America, which actually issues the applicable series of notes. In this prospectus, we refer to each series of Secured Medium-Term Notes as a “series of notes” and to Secured Medium-Term Notes in general as “notes.”

          In this prospectus, references to “United States dollars,” “U.S. dollars,” or “$” are to lawful currency of the United States of America, and references to “euro” are to the currency introduced at the start of the third stage of the European economic and monetary union pursuant to the treaty establishing the European Community, as amended.

          You should rely only on the information incorporated by reference or provided in this prospectus, the applicable prospectus supplement and the applicable pricing supplement. None of us, PFG, any trust or any of our or their respective agents or dealers has authorized any other person to provide you with different or additional information. If anyone provides you with different information, you should not rely on it. None of us, PFG, any trust or any of our or their respective agents or dealers is making an offer to sell the notes in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, the applicable prospectus supplement or the applicable pricing supplement, as well as information PFG previously filed with the SEC and incorporated by reference, is accurate only as of the date on the front cover of those documents or the date those documents were filed with the SEC, as applicable. Our and PFG’s business, financial condition, results of operations and prospects may have changed since that date. For more detail on the terms of the notes, you should read the exhibits filed with or incorporated by reference in our registration statement.

RISK FACTORS

          Your investment in the notes will involve certain risks. This prospectus and the accompanying prospectus supplement contain all of the risks that we believe are material to an investment in the notes.

          In consultation with your own financial, accounting and legal advisors, you should carefully consider the information included in or incorporated by reference in this prospectus, the accompanying prospectus supplement and the applicable pricing supplement, and pay special attention to the following discussion of risks before deciding whether an investment in the notes is suitable for you. The notes will not be an appropriate investment for you if you are not knowledgeable about significant features of the notes or financial matters in general. You should not purchase notes unless you understand, and know that you can bear, these investment risks.

          Because the applicable trust will rely on the payments that the trust receives on the funding agreement (or the related guarantee) to fund all payments on the related notes, you are making an investment decision regarding the funding agreement and the related guarantee as well as the related notes. You should carefully review the information in this prospectus, the accompanying prospectus supplement and the related pricing supplement about the notes, the funding agreement and the related guarantee.

Risk Factors Relating to Each Trust

          The principal assets of each trust will be a funding agreement (a “funding agreement”) issued by us and a related full and unconditional guarantee (a “guarantee”) issued by PFG of our payment obligations under the funding agreement. Although the trust will purchase the funding agreement relating to a particular series of notes, the trust will grant a security interest in and collaterally assign the funding agreement to the indenture trustee and the trust will collaterally assign and grant a security interest in the related guarantee to the indenture trustee, in each case for the benefit of the holders of the related series of notes to secure the trust’s obligations under that series of notes. Accordingly, each series of notes will be secured by a funding agreement and the related guarantee, together with all of the proceeds in respect of, all amounts and instruments on deposit from time to time in the relevant collection account and all of the books and records pertaining to, such funding agreement and related guarantee and all of the trust’s rights thereto, which we collectively refer to in this prospectus as the “collateral”. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular trust will be enforceable against only the assets held in such trust and not against the assets of any other trust, us or PFG. No series of notes will have any right to receive payments from the collateral related to any other series of notes issued by another trust or from our assets or PFG’s assets.

          The ability to receive payments on a series of notes will principally depend on payments under each related funding agreement and the related guarantee. Accordingly, the applicable trust will only be able to make timely payments with respect to a series of notes if we have made all required payments under the funding agreement securing the related series of notes or, if we fail to make such payments, PFG has made all required payments under the related guarantee. See “— Risk Factors Relating to the Collateral” below in this prospectus.

          The notes will not be obligations of, and will not be guaranteed by, us, PFG or any of our or its respective subsidiaries or affiliates. Except for our payment obligations under the funding agreement and the expense and indemnity agreements and the full and unconditional guarantee of our payment obligations under the funding agreement by PFG, none of us, PFG, U.S. Bank Trust National Association, as trustee (the “trustee”) or GSS Holdings II, Inc., as trust beneficial owner (the “trust beneficial owner”) is under

any obligation to provide funds or capital to the trust. In addition, the notes will not benefit from any insurance guarantee fund coverage or any similar protection. Each trust has no net worth as of the date of this prospectus, and the net worth of each trust will be approximately $15 at inception, unless otherwise specified in the applicable pricing supplement. The net worth of each trust is not expected to increase materially.

          Each trust exists solely to:

          Each trust has no prior operating history.

Risk Factors Relating to the Notes

          The notes of a series are payable only from the collateral held as security for notes of a series by the relevant trust. If any event of default occurs under any series of notes, the rights of the holders of the series of notes and the indenture trustee, acting on behalf of such holders will be limited to a proceeding against the applicable collateral. None of the holders of the affected notes or the indenture trustee, acting on behalf of such holders, will have the right to proceed against the collateral related to any other series of notes issued by another trust. Furthermore, no holder or the indenture trustee, acting on behalf of such holder, will have the ability to proceed against any of us, PFG, our or its officers, directors, affiliates, employees or agents or any of the applicable trust’s trustees, beneficial owner or agents, or any of their respective officers, directors, affiliates, employees or agents except with respect to enforcing obligations under the funding agreement against us and the guarantee of our payment obligations under that funding agreement against PFG. All claims of the holders of a series of notes in excess of amounts received from the related collateral will be extinguished.

          The funding agreement issued by us to the applicable trust will be a contractual obligation between us and that trust. Once the trust collaterally assigns and grants a security interest in all of its rights and privileges in the funding agreement to the indenture trustee for the benefit of the holders of the related series of notes to secure the trust’s obligations under such series of notes, the indenture trustee will be the only party with recourse rights against us under the funding agreement. Subject to certain conditions in the indenture, however, holders of the applicable series of notes representing a majority in aggregate principal amount of the outstanding notes of such series have the right to direct the time, method and place of conducting any proceedings for exercising any remedy available to the indenture trustee in respect of such series of notes, including with respect to the related funding agreement. See “Description of the Notes — Nonrecourse Enforcement.”

          The guarantee issued by PFG to the trust will be a contractual obligation between PFG and that trust. Once that trust collaterally assigns and grants a security interest in all of its rights and privileges in the guarantee to the indenture trustee for the benefit of the holders of the related series of notes to secure

its obligations under such notes, the indenture trustee will be the only party with recourse rights against PFG under the guarantee. Subject to certain conditions in the indenture, however, holders of the applicable series of notes representing a majority in aggregate principal amount of the outstanding notes of such series have the right to direct the time, method and place of conducting any proceedings for exercising any remedy available to the indenture trustee in respect of such series of notes, including with respect to the related guarantee. See “Description of the Notes — Nonrecourse Enforcement.”

          Since we and PFG are registrants, purchasers of notes may proceed directly against us and PFG to enforce their rights under the United States federal and state securities laws. The right by such purchasers to proceed against us, with respect to the applicable funding agreement, under the United States federal and state securities laws is no different than if we had issued the funding agreement directly to such purchasers. The right by such purchasers to proceed against PFG, with respect to the applicable guarantee, under the United States federal and state securities laws is no different than if PFG had issued the guarantee directly to such purchasers.

          In certain circumstances an event of default under a series of notes may not constitute an event of default under the applicable funding agreement and the applicable guarantee.

          To the extent that:

it is possible that the trust’s obligations under any series of notes may be accelerated while our obligations under the funding agreement and PFG’s obligations under the related guarantee may not be similarly accelerated. If this occurs, scheduled payments under the funding agreement would not be accelerated and the indenture trustee may have no or limited ability to proceed against the funding agreement and the related guarantee and holders of the trust’s notes may not be paid in full, or in a timely manner upon such acceleration. See “Description of the Notes — Events of Default” and “Description of the Funding Agreements” in this prospectus and “Risk Factors — Risk Factors Relating to the Notes — Ratings of our programs and any rated series of notes may not reflect all risks of an investment in the notes and may change in accordance with our financial strength rating.”

          Payments of the principal of and interest on a series of notes will be made solely from the payments the trust receives under the funding agreement or, if we fail to make such payments, the payments the trust receives under the related guarantee. Unless otherwise specified in the applicable prospectus supplement or pricing supplement, we or PFG will not pay any additional amounts in respect of a funding agreement to compensate for any withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or governmental charges of whatever nature imposed or levied on payments in respect of a funding agreement, by or on behalf of any governmental authority, and each holder of a note of the related series of notes will be deemed for all purposes to have received cash in an amount equal to the portion of such withholding or deduction that is attributable to such holder’s interest in the notes, as equitably determined by the trust. Under this circumstance, the trust will not actually pay, or cause to be paid, to such holder all of the amounts which would have been receivable by such holder in

the absence of such taxes, duties, levies, assessments or other governmental charges. Any such withholding or deduction will not give rise to an event of default or any independent right or obligation to redeem the affected funding agreement or the related series of notes.

          The laws and regulations of the 50 states of the United States and the District of Columbia (the “covered jurisdictions”) contain broad definitions of the activities that may constitute the business of insurance or the distribution of insurance products. Because the primary asset of the relevant trust will be a funding agreement issued by us, it is possible that insurance regulators in one or more jurisdictions could take the position that (i) the issuance of notes by the trust, or the performance of the trust’s obligations under the notes, including the payment or prepayment of amounts due under the notes, constitutes the indirect issuance of a funding agreement or other insurance product, and (ii) the distribution, transfer, sale, resale or assignment of the notes of a series constitutes the production or sale of a funding agreement or other insurance product. If such a position were to be taken in any covered jurisdiction, the underlying activity and the person conducting such activity (including the relevant trust, us, any underwriter, dealer or agent, an investor or any other person) could become subject to regulation under the insurance laws of one or more of the covered jurisdictions, which could, among other effects, require such persons to be subject to regulatory licensure or other qualification and levels of compliance that cannot practically be achieved. Failure to comply with such requirements could subject such persons to regulatory penalties. In addition, any such failure to comply or the threat of any such regulation could reduce liquidity with respect to the notes, prevent an investor from transferring notes and reduce the marketability and market value of the notes. Any financial penalty assessed against the relevant trust could affect its ability to pay amounts due under the notes. Therefore, any such regulation or threat of such regulation by any one or more covered jurisdictions could result in an investor being unable to liquidate its investment in the notes, or, upon any such liquidation, receiving a value significantly less than the initial investment in the notes.

          We believe that the notes will not be considered to be funding agreements, insurance or annuity policies or contracts or any other products regulated under the insurance laws of the covered jurisdictions and the trust will not be deemed to be engaging in the business of insurance in such jurisdictions solely as a result of such offer or sale of the notes.

          There are wide variations in the insurance laws of the covered jurisdictions, subtle nuances in their application and a general absence of any consistent pattern of interpretation or enforcement with respect to the subject regulatory issues. Insurance regulatory authorities have broad discretionary powers in administering and interpreting the insurance laws of their respective jurisdictions. Any such regulatory interpretation is not necessarily binding on any state or federal court. Any such insurance regulatory authorities or courts could take positions contrary to our beliefs described above. Accordingly, there can be no assurance that the purchase, resale, transfer or assignment of the notes will not subject the parties to such transaction to regulation or enforcement proceedings under the insurance laws of one or more covered jurisdictions, which could result in fines, penalties and other civil and criminal enforcement actions, as well as prohibiting the transfer or effectiveness of the notes without compliance with appropriate insurance licensing and other laws.

          Under our programs targeted to retail investors, we have the discretionary right to limit the aggregate principal amount of:

          In any such event, a trust shall similarly be required to limit the aggregate principal amount of notes as to which exercises of the survivor’s option shall be accepted by the trust. Accordingly, no assurance can be given that the exercise of the survivor’s option for a desired amount will be accepted as to any series of notes or in any single calendar year.

          If the funding agreement related to your notes is redeemable at our option, including our right to redeem such funding agreement if we are, or a material probability exists that we will be, if specified in the circumstances set forth in the relevant pricing supplement, required to pay additional amounts in connection with any withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or governmental charges of whatever nature imposed or levied on payments in respect of such funding agreement or the notes such funding agreement secures, by or on behalf of any governmental authority, or upon the occurrence of a “tax event” (as defined under “Description of the Funding Agreements — Early Redemption for Tax Event”), the trust will redeem your notes if we choose to redeem the related funding agreement. Each trust may issue a series of notes which may be redeemed by the issuing trust when 20% or more of the original principal balance of such notes is outstanding, which are referred to as “callable” notes. Notes that may be redeemed at the option of the trust at a time when 20% or more of the original principal amount of such notes are outstanding will be designated in their title as “callable” in the applicable pricing supplement. Prevailing interest rates at the time the trust redeems your notes may be lower than the rate borne by the notes as of their original issue date. In such a case, you generally will not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as your notes being redeemed. Our redemption right also may adversely impact your ability to sell your notes.

          Upon issuance, a series of notes will not have an established trading market. We cannot assure you a trading market for your notes will ever develop or be maintained if developed. In addition to the trust’s, PFG’s and our creditworthiness, many factors affect the trading market for, and trading value of, your notes. These factors include:

          There may be a limited number of buyers if you decide to sell your notes. This may affect the price you receive for your notes or your ability to sell your notes at all. In addition, notes that are designed for specific investment objectives or strategies often experience a more limited trading market and more price volatility than those not so designed. You should not purchase notes unless you understand and know you can bear all of the investment risks associated with your notes.

          If you invest in notes that are denominated and/or payable in a currency other than U.S. dollars, which we refer to in this prospectus and the accompanying prospectus supplement as “foreign currency notes,” you will be subject to significant risks not associated with an investment in a debt security denominated and payable in U.S. dollars. The risks include but are not limited to:

          The existence, magnitude and longevity of these risks generally depend on factors over which none of the trust, we or PFG has any control and which cannot be readily foreseen, such as:

          Moreover, if payments on your foreign currency notes are determined by reference to a formula containing a multiplier or leverage factor, the effect of any change in the exchange rates between the applicable currencies will be magnified. In recent years, exchange rates between certain currencies have been highly volatile and volatility between these currencies or with other currencies may be expected in the future. Fluctuations between currencies in the past are not necessarily indicative, however, of fluctuations that may occur in the future. Depreciation of your payment currency would result in a decrease (1) in the U.S. dollar equivalent yield of your foreign currency notes, (2) in the U.S. dollar equivalent value of the principal and any premium payable at maturity or any earlier redemption of your foreign currency notes and (3) generally in the U.S. dollar equivalent market value of your foreign currency notes.

          Governments have imposed from time to time, and may in the future impose, exchange controls that could affect exchange rates as well as the availability of a specified currency other than U.S. dollars at the time of payment of principal, any premium or interest on a foreign currency note. Governments may use a variety of techniques, such as intervention by a country’s central bank, the imposition of regulatory controls or taxes or changes in interest rates to influence the exchange rates of their currencies. Governments may also alter the exchange rate or relative exchange characteristics by a devaluation or revaluation of a currency. There can be no assurance that exchange controls will not restrict or prohibit payments of principal, any premium or interest denominated in any such specified currency.

          Even if there are no actual exchange controls, it is possible that the specified currency would not be available to us when payments on a funding agreement are due because of circumstances beyond our

control. In this event, we will make required payments in U.S. dollars on the basis described in the accompanying prospectus supplement or the applicable pricing supplement. You should consult your own financial and legal advisors as to the risks of an investment in notes denominated in a currency other than U.S. dollars.

          The information set forth in this prospectus and the accompanying prospectus supplement is directed to prospective purchasers of notes who are United States residents. The trust, we and PFG disclaim any responsibility to advise prospective purchasers who are residents of countries other than the United States regarding any matters that may affect the purchase or holding of, or receipt of payments of principal of, or premium or interest on, notes. Such persons should consult their advisors with regard to these matters.

          In the event that the programs generally or a specific series of notes is rated by a rating agency, the ratings of the programs or such notes will primarily reflect our financial strength and will change in accordance with our financial strength rating and with any change in the priority status of funding agreement obligations under Iowa law. Any rating is not a recommendation to purchase, sell or hold any particular security, including the notes. Such ratings do not comment as to the market price or suitability of the notes for a particular investor. In addition, there can be no assurance that a rating will be maintained for any given period of time or that a rating will not be lowered or withdrawn in its entirety. The ratings of our secured medium-term notes program and our program targeted to retail investors and any rated series of notes issued under these programs may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or trading value of, your notes.

          If market interest rates increase above the interest rate of fixed rate notes, then fixed rate notes generally decline in value because debt instruments of the same face value priced at market interest rates will yield higher income. Consequently, if you purchase fixed rate notes and market interest rates increase above the fixed interest rate on the notes you have purchased, the market value of your notes may decline. Neither we nor PFG can give any assurance regarding the future level of market interest rates.

          If you purchase discount notes, the amount payable to you upon early redemption, repayment or acceleration of these notes may be less than the principal amount thereof plus accrued and unpaid interest. The amount payable will be determined by the formula set forth in the applicable prospectus supplement or pricing supplement.

Risk Factor Relating to the Collateral

          The funding agreements are our unsecured obligations and, in the event of our impairment or insolvency, the Iowa Insurance Commissioner will be authorized and directed to commence delinquency proceedings for the purpose of liquidating, rehabilitating, reorganizing or conserving us pursuant to Iowa Code Sections 507C.4, 507C.12, 507C.13, 507C.14 and 507C.16. In conducting delinquency proceedings, claims are prioritized and an order of distribution is specified pursuant to Iowa Code Section 507C.42.

There are nine classes within the priority scheme, with each successive class being fully junior to the preceding class. Sidley Austin LLP, counsel to us and PFG, has opined that, subject to the limitations, qualifications and assumptions set forth in its opinion letter, in a properly prepared and presented case, a court applying Iowa law would conclude that loss claims of principal and interest in respect of each funding agreement would be accorded Class 2 priority under Iowa Code Section 507C.42 and paid equally in priority with our other policyholders.

          Sidley Austin LLP has advised that its opinion is based on its interpretation of the relevant provisions of the Iowa Code as construed by relevant administrative and judicial authority. However, the Iowa Code and regulations, interpretations and decisions are subject to change, either prospectively or retroactively, and many of the issues addressed in counsel’s opinion depend upon a facts and circumstances analysis that has received little or no administrative or judicial consideration. Therefore, the Iowa Insurance Commissioner, in his/her capacity as liquidator, rehabilitator or otherwise, or the courts could disagree in whole or in part with our analysis.

          In the event that a funding agreement were not accorded Class 2 priority in our insolvency, the funding agreement would be accorded the lower priority associated with our general unsecured obligations, which would adversely affect the ability of the applicable trust to recover any claims of principal and interest in respect of such funding agreement. See “Description of the Funding Agreements — Priority.”

          Iowa law would apply to our insolvency or receivership proceedings. Investors should note, however, that the statutory liquidation priority accorded to funding agreements under Iowa law does not clearly apply to any additional amounts required to be paid (if specified in the applicable pricing supplement) as may be necessary in order that the net amounts receivable by a holder after any withholding or deduction under United States tax law shall equal the respective amounts which would have been receivable by such holder in the absence of such withholding or deduction. Accordingly, claims for such payments, if any, may not rank equally with either life insurance policy and annuity claims or funding agreement claims, and may rank with our unsecured debt obligations, which would adversely affect the ability of the applicable trust to recover any claims of additional amounts in respect of such funding agreement. See “Description of the Funding Agreements.”

          Each guarantee will be issued by PFG, our indirect parent company. We represent a substantial portion of the assets of PFG. In the event of our insolvency or receivership, PFG may incur limitations in receiving any distributions from us. In such an event, PFG may have limited resources to satisfy its obligations under the guarantees.

Risk Factors Relating to PFG

          PFG attempts to reduce the impact of changes in interest rates on the profitability and surplus of its asset accumulation and life and health insurance operations. PFG accomplishes this reduction primarily by managing the duration of its assets relative to the duration of its liabilities. During a period of rising interest rates, policy surrenders, withdrawals and requests for policy loans may increase as customers seek to achieve higher returns. Despite PFG’s efforts to reduce the impact of rising interest rates, it may be required to sell assets to raise the cash necessary to respond to such surrenders, withdrawals and loans, thereby realizing capital losses on the assets sold. An increase in policy surrenders and withdrawals may also require PFG to accelerate amortization of policy acquisition costs relating to these contracts, which would further reduce its net income.

          During periods of declining interest rates, borrowers may prepay or redeem mortgages and bonds that PFG owns, which would force PFG to reinvest the proceeds at lower interest rates. For some of PFG’s products, such as guaranteed investment contracts and funding agreements, PFG is unable to lower the rate it credits to customers in response to the lower return it will earn on its investments. In addition, it may be more difficult for PFG to maintain its desired spread between the investment income it earns

and the interest it credits to its customers during periods of declining interest rates thereby reducing PFG’s profitability.

          Ratings are important factors in establishing the competitive position of insurance companies. A downgrade, or the potential for such a downgrade, of any of our ratings could, among other things:

          Any of these consequences could adversely affect PFG’s profitability and financial condition.

          PFG’s investment portfolio is subject to several risks, including, among other things:

          Any of these consequences may diminish the value of PFG’s invested assets and adversely affect its sales, profitability or the investment returns credited to its customers.

          PFG’s insurance business is subject to comprehensive state regulation and supervision throughout the United States. The primary purpose of state regulation of the insurance business is to protect policyholders, and not necessarily to protect other constituencies such as creditors or investors. State insurance regulators and the National Association of Insurance Commissioners continually reexamine existing laws and regulations and may impose changes in the future. Changes in federal legislation and administrative policies in areas such as employee benefit plan regulation, financial services regulation and federal taxation could result in increased exposure on outstanding products or reduced sales of new products and therefore, could reduce PFG’s profitability.

          Actual results may differ materially from those included in the forward-looking statements as a result of risks and uncertainties including, but not limited to, the following: (1) a decline or increased volatility in the securities markets could result in investors withdrawing from the markets or decreasing their rates of investment, either of which could reduce PFG’s net income, revenues and assets under management; (2) PFG’s investment portfolio is subject to several risks which may diminish the value of invested assets and affect its sales, profitability and the investment returns credited to its customers; (3) competition from companies that may have greater financial resources, broader arrays of products, higher ratings and stronger financial performance may impair PFG’s ability to retain existing customers, attract new customers and maintain its profitability; (4) a downgrade in our financial strength ratings may increase policy surrenders and withdrawals, reduce new sales and terminate relationships with distributors and cause some of PFG’s existing liabilities to be subject to acceleration, additional collateral support, changes in terms or creation of additional financial obligations; (5) PFG’s efforts to reduce the impact of interest rate changes on its profitability and surplus may not be effective; (6) if PFG is unable to attract and retain sales representatives and develop new distribution sources, sales of its products and services may be reduced; (7) PFG’s international businesses face political, legal, operational and other risks that could reduce its profitability in those businesses; (8) PFG reserves established for future policy benefits and claims may prove inadequate, requiring it to increase liabilities; (9) PFG’s ability to pay stockholder dividends and meet its obligations may be constrained by the limitations on dividends Iowa insurance laws impose on us; (10) PFG may need to fund deficiencies in our closed block (“Closed Block”) assets which benefit only the holders of Closed Block policies; (11) changes in laws, regulations, accounting standards or interpretations thereof may reduce the profitability of PFG; (12) litigation and regulatory investigations may harm PFG’s financial strength and reduce its profitability; (13) fluctuations in foreign currency exchange rates could reduce PFG’s profitability; (14) applicable laws and PFG’s stockholder rights plan, certificate of incorporation and by-laws may discourage takeovers and business combinations that PFG’s stockholders might consider in their best interests; and (15) a downgrade in PFG’s debt ratings may adversely affect PFG’s ability to secure funds and cause some of its existing liabilities to be subject to acceleration, additional collateral support, changes in terms or creation of additional financial obligations.

          You should not place undue reliance on these forward-looking statements, which speak only as of their dates. Except as required by the federal securities laws, we, PFG, each trust, and our or their respective agents and dealers shall not undertake any obligation to update or review forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to projections over time.

USE OF PROCEEDS

          Each trust will use the net proceeds from the issuance of its series of notes to the public and the trust beneficial interest to the trust beneficial owner to purchase a funding agreement issued to, and deposited into, that trust by us. We intend to use the net proceeds from the sale to the trust of the funding agreement to purchase investment assets. We expect such assets, and our other general account assets, will generate investment income in excess of amounts payable under the funding agreement.

RATIO OF EARNINGS TO FIXED CHARGES

          The following table sets forth, for the years and periods indicated, PFG’s ratios of:

          PFG calculates the ratio of “earnings to fixed charges before interest credited on investment products” by dividing the sum of income from continuing operations before income taxes (BT), interest expense (I), interest factor of rental expense (IF) less undistributed income from equity investees (E) by the sum of interest expense (I), interest factor of rental expense (IF) and dividends on majority-owned subsidiary redeemable preferred securities (non-intercompany) (D). The formula for this ratio is: (BT+I+IF-E)/(I+IF+D).

          PFG calculates the ratio of “earnings to fixed charges” by dividing the sum of income from continuing operations before income taxes (BT), interest expense (I), interest factor of rental expense (IF) less undistributed income from equity investees (E) and the addition of interest credited on investment products (IC) by interest expense (I), interest factor of rental expense (IF), dividends on majority-owned subsidiary redeemable preferred securities (non-intercompany) (D) and interest credited on investment products (IC). The formula for this calculation is: (BT+I+IF-E+IC)/(I+IF+D+IC). “Interest credited on investment products” includes interest paid on guaranteed investment contracts, funding agreements, medium-term notes and other investment-only pension products. Similar to debt, these products have a total fixed return and a fixed maturity date.

On July 1, 1998, Principal Mutual Life Insurance Company converted to a mutual holding company structure, changed its name to Principal Life Insurance Company and created Principal Mutual Holding Company, a mutual insurance holding company, and Principal Financial Services, Inc. (“PFS”), an intermediate holding company.

          Consistent with Iowa law in a process sometimes referred to as a “demutualization”, Principal Mutual Holding Company, under the terms of its plan of conversion, converted from a mutual insurance holding company to a stock company subsidiary of PFG, a Delaware business corporation, effective October 26, 2001. All membership interests in Principal Mutual Holding Company were extinguished on that date and eligible policyholders received compensation in the form of common stock, cash or policy credits.

          After giving effect to the reorganization resulting from the demutualization, we are now a direct wholly-owned subsidiary of PFS, which, in turn, is a direct wholly-owned subsidiary of PFG.

          In connection with the issuance of a series of notes by an issuing trust, we will issue a funding agreement to such issuing trust with pricing terms substantially similar to that trust’s series of notes, will procure the related guarantee from PFG, will make payments under the funding agreement, as required, and will file the reports for the issuing trust, as required by the Securities Exchange Act of 1934, as amended. We have been engaged in the securitization of funding agreements as sponsor or depositor in connection with an existing $4.0 billion secured notes program which is substantially identical to this program and was declared effective by the SEC in March 2004. We have also been engaged in the securitization of funding agreements in connection with private placement facilities similar in structure to this program since 1998.

          We are authorized to issue up to $4.0 billion of funding agreements under a program established in 1998 to support the prospective issuance of medium-term notes by an unaffiliated entity in non-U.S. markets.

          In addition, we are authorized to issue up to $7.0 billion of funding agreements under a program established in 2001 to support the prospective private issuance of medium-term notes by an unaffiliated entity in both domestic and international markets. We do not anticipate any new issuance activity under that program, in light of our other $4.0 billion secured notes program declared effective by the SEC in March 2004 and this program once declared effective by the SEC.

DESCRIPTION OF THE TRUSTS

          The following is a general description of the trusts and the material provisions of the standard trust terms which will be incorporated into each trust agreement and other related documents governing the trusts. The trust agreement is included in the form of omnibus instrument. This summary is not intended to be a full restatement of all of the terms of the standard trust terms or the trust agreement and is subject to the detailed provisions of such documents. Copies of the standard trust terms and the form of omnibus instrument (including the form of trust agreement) have been filed as exhibits to the registration statement (which includes this prospectus) and are incorporated into this prospectus by reference. Executed copies of the applicable trust agreement may be inspected during normal business hours at our principal executive offices set forth on the cover page of this prospectus.

General

          A separate trust will be created for each series of notes. Each trust will be a separate and distinct special purpose common law trust formed in a jurisdiction located in the United States of America specified in the applicable pricing supplement. Each trust will be organized pursuant to, and governed by, a trust agreement, dated as of the date of the applicable pricing supplement, between the trustee and the trust beneficial owner. The trust agreement will adopt and incorporate the standard trust terms in its entirety. With respect to a particular trust, we refer to the applicable trust agreement and the standard trust terms as the “trust agreement.” The assets and liabilities of each trust will be separate and distinct from the assets and liabilities of every other trust, us and PFG.

          In connection with the issuance of a series of notes by a trust:

          Each trust’s principal executive offices will be located at c/o U.S. Bank Trust National Association, 100 Wall Street, 16th Floor, New York, New York 10005 and its telephone number is (212) 361-6184.

Nature of Each Trust

          The trust agreement provides that each trust will be a separate and distinct special purpose common law trust formed in a jurisdiction located in the United States of America specified in the applicable pricing supplement.

          The applicable series of notes and the liabilities, obligations and expenses related to such series of notes will constitute debt, liabilities, obligations and expenses incurred, contracted for or otherwise of the applicable trust.

          As separate and distinct special purpose trusts, the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular trust will be enforceable only against the assets of such trust and not against the assets of any other trust, us or PFG. In addition, none of the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to us, PFG or any trust will be enforceable against the assets of any other trust. See “Description of the Notes — Nonrecourse Enforcement.”

Application of Money Received by the Trustee on Behalf of a Trust

          Except for payments made in connection with the liquidation of a trust, all monies and other property received by the trustee on behalf of a trust shall be distributed as follows:

          first, to the indenture trustee for the payment of all amounts then due and unpaid upon the applicable notes, if any, in accordance with the applicable indenture; and

          second, to the trust beneficial owner for the payment of all amounts that would be payable to the trust beneficial owner if the trust beneficial owner held a note with an original principal amount of $15 (multiplied by the issue price of the related notes in the case of discount notes); any remaining monies and other property shall be distributed ratably in proportion to their original principal amounts to the holders of notes last noted in the register as the holders of the notes and trust beneficial owner (as if the trust beneficial owner held a note with an original principal amount of $15 (multiplied by the issue price of the related notes in the case of discount notes)).

          Upon the liquidation of a trust, the remaining collateral and any other assets held in the trust shall be liquidated, and the trust shall be wound-up by the trustee in accordance with the trust agreement. In such event, (i) the trust shall first pay all amounts due and unpaid on the notes, if any, in accordance with the applicable indenture, (ii) the trust shall then pay any other claims, including expenses relating to such liquidation to the extent not paid, or reasonably provided for, pursuant to the applicable expense and indemnity agreement, and (iii) the trust shall then pay to the trust beneficial owner all amounts that would be payable under the indenture to the trust beneficial owner if the trust beneficial owner held a note with an original principal amount of $15 (multiplied by the issue price of the related notes in the case of discount notes). Any remaining monies and other property shall be paid ratably in proportion to their original principal amounts to the holders last noted in the register as the holders of the notes and the trust beneficial owner (as if the trust beneficial owner held a note with an original principal amount of $15 (multiplied by the issue price of the related notes in the case of discount notes) and as if each such holder continued to hold its notes after all amounts due on such notes under the indenture have been paid).

Bankruptcy Concerns

          In the trust agreement, the trustee and the trust beneficial owner agree that neither party will institute against the trust any bankruptcy proceeding. Also, in the indenture, the indenture trustee agrees that it will not institute against the trust any bankruptcy proceeding for payments due the indenture trustee. However, during the occurrence and continuance of an event of default, the indenture trustee (on behalf of the holders of notes) or the holders of notes may accelerate payments of principal and interest under the notes as well as institute bankruptcy proceedings against the trust. If a bankruptcy proceeding is commenced against the trust, we do not anticipate that the assets of the trust will be consolidated with the assets of any other party. As the primary asset of each trust is a funding agreement issued by us, upon a proceeding for our liquidation, rehabilitation, conservation or supervision or similar event, an event of default under the notes issued by each trust will occur and the indenture trustee on behalf of the noteholders will have a claim against us in such proceeding. We have been advised by counsel that such claim will be a policyholder claim against our assets. See “Description of The Funding Agreements — Priority”. No other creditors or policyholders of ours should have a claim against the funding agreement held by each trust or any claims thereunder. Although PFG issues a guarantee to each trust, a proceeding for PFG’s liquidation, rehabilitation, conservation or supervision or similar event may not result in an event of default under the notes if we continue to make payments received under the related funding agreement. In such event, if we do not make the required payments under any funding agreement, an event of default under the related notes will occur and the indenture trustee on behalf of the noteholders will be able to make a claim against us, and against PFG in a bankruptcy proceeding of PFG.

The Trustee

          Pursuant to each trust agreement, the trustee is acting as the sole trustee of the applicable trust. The trustee will conduct the activities of each trust. The trustee will only perform those duties set forth in each trust agreement. Among other items, the trustee, on behalf of the trust, will:

          The trustee will not be liable under the trust agreement under any circumstances or for any action or failure to act, except for (i) its own willful misconduct, bad faith or negligence or (ii) the inaccuracy of any representation or warranty contained in the trust agreement made by the trustee.

          The trustee may resign by giving at least 60 days written notice to the trust beneficial owner and the indenture trustee. If at any time the trustee ceases to be eligible to serve as the trustee under a trust agreement, or the trustee is unable to serve as trustee, or is bankrupt or insolvent, then the trust beneficial owner and the indenture trustee may remove the trustee. No resignation or removal of the trustee and no appointment of a successor trustee shall become effective until the acceptance of appointment by the successor trustee.

          U.S. Bank Trust National Association (“U.S. Bank Trust”) will act as trustee under the applicable trust agreements. U.S. Bank Trust is a national banking association and a wholly-owned subsidiary of U.S. Bancorp, which is currently ranked as the sixth largest bank holding company in the United States with total assets exceeding $204 billion. U.S. Bancorp serves approximately 13.1 million customers, operates 2,383 branch offices in 24 states and has over 51,000 employees. A network of specialized U.S. Bancorp offices across the nation, inside and outside its 24-state footprint, provides a comprehensive line of banking, brokerage, insurance, investment, mortgage, trust and payment services products to consumers, businesses, governments and institutions.

          U.S. Bank Trust provides trustee services from at least 5 U.S. cities. The indenture will be administered from U.S. Bank Trust’s office located at 100 Wall Street, New York, New York 10005.

          U.S. Bank Trust or its predecessors have provided fiduciary services since 1924. As of December 30, 2004, U.S. Bank Trust was acting as trustee with respect to over 60,000 issuances of securities. U.S. Bank Trust has acted as trustee of insurance policy-backed securities since 2003. As of September 30, 2005, U.S. Bank Trust was acting as trustee on 2 issuances of insurance policy-backed securitizations, involving more than 200 series of such securities with an outstanding aggregate principal balance of approximately $3,500,000,000.

The Trust Beneficial Owner

          GSS Holdings II, Inc. as the trust beneficial owner will be the sole beneficial owner of each trust. The beneficial interest in each trust:

          The trust beneficial owner will receive periodic distributions on its beneficial interest at the same rate and on the same day that holders of notes of the related series of notes receive interest payments. On the maturity date of the trust beneficial owner’s beneficial interest and the related series of notes, the trust will redeem the principal amount of the related series of notes and the principal amount of the trust beneficial interest.

No Affiliation

          None of us, PFG or any of our or its officers, directors, subsidiaries or affiliates owns any beneficial interest in any trust nor has any of these persons or entities entered into any agreement with any trust other than in furtherance of the issuance of notes from time to time as contemplated by this prospectus.

          None of us, PFG or any of our or its officers, directors, subsidiaries or affiliates is affiliated with the trustee, the trust beneficial owner or the indenture trustee relating to the notes.

Recordkeeping

          Each trust will:

          On behalf of the trusts, as depositor, we will be subject to certain reporting requirements under the Securities Exchange Act of 1934, as amended.

Expenses

          We have entered into a separate expense and indemnity agreement with each of the indenture trustee, the custodian (see “Description of the Notes — Collateral”), the trust beneficial owner and the trustee (on behalf of itself and each trust to be formed in connection with the issuance of a series of notes). We will enter into an expense and indemnity agreement with additional service providers appointed from time to time. Under each expense and indemnity agreement, we will pay certain costs and expenses relating to the offering, sale, issuance and administration of any series of notes and certain costs, expenses and taxes incurred by a trust and will indemnify the indenture trustee, the custodian, the trust beneficial owner, the trustee, each trust and additional service providers with respect to certain matters. Forms of each expense and indemnity agreement have been filed as exhibits to the registration statement (which includes this prospectus) and are incorporated into this prospectus by reference. Executed copies of each expense and indemnity agreement may be inspected during normal business hours at our principal executive offices set forth on the cover page of this prospectus. See “Fees and Expenses” below.

Amendment

          The trust agreement may be amended by the trustee and the trust beneficial owner:

          Subject to the second and third bullet points above, the trustee and the trust beneficial owner may amend the trust agreement, without the consent of any noteholder, at any time to the extent necessary to ensure that the applicable trust will be disregarded or treated as a grantor trust (assuming that any such trust were not disregarded) for United States federal income tax purposes or to ensure that the applicable trust will not be required to register as an investment company under the Investment Company Act of 1940, as amended. We shall advise each rating agency that is then rating the program or any series of notes of any such amendment.

DESCRIPTION OF THE NOTES

          The following is a general description of the terms of the notes. We will provide specific terms of a series of notes in the applicable prospectus supplement and a pricing supplement to this prospectus. For purposes of this prospectus, “business day” shall have the meaning set forth in the applicable prospectus supplement or the applicable pricing supplement.

          Each series of notes will be issued pursuant to an indenture, between the applicable trust and Citibank, N.A., as indenture trustee (the “indenture trustee”), which will adopt and incorporate the standard indenture terms in its entirety. The indenture is included in the form of omnibus instrument. Copies of the form of standard indenture terms and the form of omnibus instrument (including the form of indenture) are filed as exhibits to the registration statement (of which this prospectus is a part) and is incorporated into this prospectus by reference. With respect to a particular trust, we refer to the applicable indenture and the standard indenture terms as the “indenture.” The following summary highlights some of the provisions of the indenture, but it may not contain all of the information that is important to you. We do not restate the indenture in its entirety and we urge you to read the indenture, which is filed as an exhibit to the registration statement of which this prospectus forms a part.

General

          Except as described in the applicable prospectus supplement or the applicable pricing supplement, the indenture does not limit the amount of notes that a trust may issue, and a trust may only issue notes in one series. A series of notes will be the trust’s unconditional, direct, non-recourse, secured and unsubordinated obligations. Each series of notes will be secured by a funding agreement relating to that series of notes and the related guarantee issued by PFG.

          The notes may be offered to institutional or retail investors. Notes offered to institutional investors will be offered under the prospectus supplement to this prospectus relating to our secured medium-term notes program. These notes:

          Each fixed rate note offered to institutional investors will bear interest at the rate specified in the applicable pricing supplement. Each floating rate note offered to institutional investors will bear interest at a rate determined by reference to one or more of the following interest rate bases, which will be specified in the applicable pricing supplement:

          These interest rate bases are further described in the prospectus supplement to this prospectus relating to our secured medium-term notes program.

          Notes offered to retail investors will be offered under the prospectus supplement to this prospectus relating to the Principal^® Life CoreNotes^® program or the prospectus supplement to this prospectus relating to the secured medium-term notes retail program. These notes:

          Each fixed rate note offered to retail investors will bear interest at the rate specified in the applicable pricing supplement. Each floating rate note offered to retail investors will bear interest at a rate determined by reference to one or more of the following interest rate bases, which will be specified in the applicable pricing supplement:

          These interest rate bases are further described in the prospectus supplement to this prospectus relating to the Principal^® Life CoreNotes^® program or the prospectus supplement to this prospectus relating to the secured medium-term notes retail program.

          At the time of sale of a series of notes, at least one nationally recognized statistical rating organization will have rated the notes in one of its generic rating categories which signifies investment grade.

          Material United States federal income tax considerations relating to the notes will be described in the applicable prospectus supplement.

          Each indenture and the notes will be governed by the internal laws of the State of New York.

Collateral

          Under the indenture, the funding agreement issued to and deposited into a trust by us in exchange for the proceeds received by the trust from the offering of its series of notes will be collaterally assigned by the trust, and the trust will grant a security interest in the funding agreement, to the indenture trustee for the benefit of the holders of the related series of notes. The trust will also collaterally assign and grant a security interest in the guarantee issued by PFG to the trust in favor of the indenture trustee for the benefit of the holders of the related series of notes. Accordingly, each series of notes will be secured by a perfected security interest in the “collateral,” consisting of:

          Under the custodial agreement entered into among the indenture trustee, Bankers Trust Company, N.A. (the “custodian”) and the trustee (on behalf of each trust to be formed in connection with the issuance of a series of notes), upon the collateral assignment of and grant of security interest in the funding agreement and the guarantee related to a series of notes of a trust, the custodian will hold the funding agreement and the guarantee, on behalf of the indenture trustee in the State of Iowa.

Covenants

          Under the indenture, the trust will make certain covenants to the indenture trustee for the benefit of noteholders. In addition, the indenture requires the trust to hold funds in trust for payments under the notes, pay to the indenture trustee, acting in its capacity as servicer, principal, interest and premium (if any) due on the notes and take all necessary action to protect the collateral. Further, the trust is obligated to deliver to the indenture trustee an annual statement certifying its compliance with the conditions, performance of obligations and adherence to covenants under the indenture. In addition to its other covenants, the trust has agreed that it will not, so long as any notes of its series are outstanding, take any of the following actions, except as otherwise permitted by the indenture:

Events of Default

          Upon the occurrence of an Event of Default (as defined below), the notes may become due and payable at an amount equal to the outstanding principal amount plus accrued but unpaid interest and any other amounts payable or, if such notes are non-interest bearing, the amortized face amount of such notes or such other redemption amount as may be specified in the applicable pricing supplement.

          The following will be Events of Default under the notes of any series:

          When an Event of Default specified in the fourth, fifth or eighth bullet point above shall have occurred and be continuing, the indenture trustee or the holder(s) of at least 25% in aggregate principal amount of the outstanding notes of the affected series may, by written notice to the trust and the indenture

trustee (if applicable), declare the principal of and all accrued and unpaid interest and any other amounts payable on the notes of such series to be due and payable. Such amounts shall become due and payable on the date the written declaration is received by the trust. This provision, however, is subject to the condition that, at any time after the principal of the notes of such series shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered, the holder(s) of at least 66²/3% in aggregate principal amount of the notes of such series then outstanding by written notice to the trust and the indenture trustee may rescind and annul such declaration and its consequences with respect solely to such series, subject to certain conditions, but no such rescission and annulment shall affect any subsequent default or shall impair any right consequent thereon. If an Event of Default specified in the first, second, third, sixth or seventh bullet point above occurs, the principal of and accrued and unpaid interest and any other amounts payable on the notes of such series will be immediately due and payable without any declaration or other action by the trust, the indenture trustee or the holder of any note.

          The Events of Default described above (other than the Event of Default specified in the third bullet point above) are different from the funding agreement defaults described later in this prospectus under the heading “Description of the Funding Agreements.” In certain circumstances, an Event of Default may occur and give rise to an acceleration of principal and interest on the notes of a series without there being a corresponding funding agreement default and acceleration of payment obligations under the related funding agreement. In such a case, there would be no or limited funds available to pay the accelerated principal and interest under the notes. In such a case, the indenture trustee, acting for the benefit of the holders of the applicable series of notes, will be limited to a proceeding against the funding agreement and the related collateral. However, because under such circumstances we would not be under any obligation to accelerate our payment obligations under the funding agreement, the indenture trustee could only:

          Any such disposition of collateral could be made on unfavorable terms and result in material losses to the holders of the applicable series of notes.

          An event of default under the PFG guarantee relating to a series of notes will not be an Event of Default with respect to such series of notes or under the indenture.

          We shall advise each rating agency that is then rating the program or any series of notes of any such Event of Default.

Application of Money Collected Under the Indenture

          On or prior to the issue date of a series of notes, we will establish a collection account with the indenture trustee in the name of the trust. This account shall collect payments received under the applicable funding agreement for the benefit of the related noteholders and shall be segregated from any other account maintained by the indenture trustee.

          Following an Event of Default and during the continuance thereof, with respect to a series of notes, any moneys that may then be held or thereafter received by the indenture trustee as security with respect to the notes of such series shall be held in the relevant collection account and shall be applied in the following order, at the dates and manner fixed by the indenture trustee:

          first, to the payment of the reasonable and customary expenses and counsel fees incurred by the indenture trustee and any other amounts due and unpaid to the indenture trustee by the trust, in an

aggregate amount of no more than $250,000 for all series of notes issued by all trusts outstanding, to the extent not paid pursuant to the expense and indemnity agreements;

          second, to the payment of the amounts then due and unpaid upon the notes of the relevant series for principal and interest and all other amounts in respect of which or for the benefit of which such amount has been collected, ratably, without preference or priority of any kind, according to the aggregate principal amounts due and payable on such notes; and

          third, any remaining balance shall be paid to the trust and such remaining balance shall be distributed by the trustee in accordance with the trust agreement as described under “Description of the Trusts — Application of Money Received by the Trustee on Behalf of a Trust.”

          If no Event of Default exists, the following priority of payments shall apply:

          first, to the payment of the amounts then due and unpaid upon the notes of the relevant series for principal and interest and all other amounts in respect of which or for the benefit of which such amount has been collected, ratably, without preference or priority of any kind, according to the aggregate principal amounts due and payable on such notes; and

          second, any remaining balance shall be paid to the trust and such remaining balance shall be distributed by the trustee in accordance with the trust agreement as described under “Description of the Trusts — Application of Money Received by the Trustee on Behalf of a Trust.”

          We will pay the costs and expenses incurred by a trust under the expense and indemnity agreements with each of the indenture trustee, the custodian, the trust beneficial owner and the trustee (on behalf of itself and the trust) and any additional service provider appointed from time to time. See “Fees and Expenses.”

          Except as expressly set forth in the indenture, none of the indenture trustee, any paying agent, registrar or any of their successors, employees, officers, directors, affiliates or agents shall have any claim or rights of any nature in or to the relevant collateral, whether as a result of set-off, banker’s lien or otherwise.

Certain Rights of Holders

          The holder(s) of a majority in aggregate principal amount of the notes of any series at the time outstanding, who provide the indenture trustee with indemnification satisfactory to the indenture trustee, shall have the right to direct the time, method, and place of conducting any proceeding for exercising any remedy available to the indenture trustee or exercising any trust or power conferred on the indenture trustee by the indenture, in each case solely in respect of such series of notes, including with respect to the collateral, provided, however, that such direction shall not be in conflict with any rule of law or the indenture and the indenture trustee may take any other action deemed proper by the indenture trustee that is not inconsistent with such direction.

          No holder of the notes of a series shall have any right to institute any proceedings, judicial or otherwise, with respect to the indenture or any agreement or instrument included in the collateral for such series of notes or for the appointment of a receiver or trustee, unless:

          With respect to the above, no holder(s) of notes shall have any right in any manner whatever by virtue of, or by availing of, any provision of the indenture to affect, disturb or prejudice the rights of any other holder of any note of the relevant series or to obtain or to seek to obtain priority or preference over any other holder of any note of the relevant series to enforce any right under the indenture, except in the manner therein provided and for the equal and ratable benefit of all the holders of the notes of the relevant series.

          Notwithstanding the foregoing, nothing in the notes of the relevant series or the indenture will prevent any relevant holder from enforcing its right to receive payment of the principal of and interest on such notes, or any other amount payable under such notes or the indenture, when and to the extent such payments become due and such rights will not be impaired without the consent of such holder.

          Since we and PFG are registrants, purchasers of notes may proceed directly against us and PFG to enforce their rights under the United States federal and state securities laws. The right by such purchasers to proceed against us, with respect to the applicable funding agreement, under the United States federal and state securities laws is no different than if we had issued the funding agreement directly to such purchasers. The right by such purchasers to proceed against PFG, with respect to the applicable guarantee, under the United States federal and state securities laws is no different than if PFG had issued the guarantee directly to such purchasers.

Reports to Holders

          Pursuant to the terms of each indenture, within ten days following any distribution made or scheduled to be made on the notes, the indenture trustee shall deliver to us a report that contains the relevant payment information, the current principal amount of the notes and applicable funding agreement and the compensation received by the indenture trustee during the period relating to such payment. As depositor, we will file this report as an exhibit to the distribution report on Form 10-D within fifteen days of the distribution date. As depositor, we will also file an annual report with respect to each trust on Form 10-K. For information on receiving copies of these reports, see “Where You Can Find More Information” above.

          In accordance with the terms of the Trust Indenture Act of 1939, as amended, the indenture trustee will be required to transmit to holders of notes reports with respect to certain matters, including any changes to the eligibility and qualifications of the indenture trustee, conflicting interests of the indenture trustee, any unpaid advances made by the indenture trustee, and any actions by the indenture trustee that materially affect the applicable notes or collateral. A copy of each such report shall, at the time of such transmission to holders of notes, be filed with each stock exchange upon which the applicable note may be listed, and also with the SEC.

Modifications and Amendments

          The trust may enter into a supplemental indenture with the indenture trustee at any time, without the consent of any holder of notes, for the purpose of:

          We shall advise each rating agency that is then rating the program or any series of notes of any such supplemental indenture.

          The trust and the indenture trustee may enter into one or more supplemental indentures for the purpose of making any amendment or modification to the notes of the applicable series or the indenture or modifying in any manner the rights of any holder of notes with consent of the holder(s) representing a majority in aggregate principal amount of the notes of the applicable series at the time outstanding. However, no such supplemental indenture may, without the affirmative consent or affirmative vote of the holder of each note of the applicable series affected thereby:

          We shall advise each rating agency that is then rating the program or any series of notes of any such supplemental indenture.

          The trust will not enter into any supplemental indenture with the indenture trustee (either with or without the consent of the holders of notes) that would cause any trust not to be disregarded or treated as a grantor trust (assuming any such trust were not disregarded) for United States federal income tax purposes.

Indenture Trustee and Servicer

          Under the indenture, if an Event of Default with respect to the applicable series of notes has occurred and is continuing, the indenture trustee is obligated to exercise such of the rights and powers vested in it by the indenture, and to use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

          Except during the continuance of an Event of Default, the indenture provides that the indenture trustee shall perform only those duties that are specifically set forth therein, and no implied covenants or obligations of the indenture trustee will be read into the indenture.

          No provision of the indenture will be construed to relieve the indenture trustee from liability for its own negligent action, its own negligent failure to act or its own bad faith or willful misconduct, except that:

          The indenture trustee may resign at any time by giving not less than 60 days’ prior written notice thereof to the trust and the holders of the applicable series of notes. If no successor indenture trustee shall have accepted appointment within 30 days after the giving of such notice of resignation, the resigning indenture trustee may petition any court of competent jurisdiction for the appointment of a successor indenture trustee.

          If at any time:

then, the trust (except upon the occurrence and during the continuation of an Event of Default) may petition any court of competent jurisdiction to remove the indenture trustee with respect to such series of notes and appoint a successor indenture trustee.

          In addition to the right of petition given to the resigning indenture trustee and the right of removal given to the trust pursuant to the preceding paragraphs, any holder who has been a bona fide holder of notes of the applicable series for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor indenture trustee or the removal of the indenture trustee and the appointment of a successor indenture trustee, as the case may be.

          Holders of a majority in aggregate principal amount of the notes of the applicable series at the time outstanding may at any time remove the indenture trustee with respect to the notes of the applicable series and appoint a successor indenture trustee with respect to the notes of the applicable series by delivering to the indenture trustee so removed, to the successor indenture trustee so appointed and to the trust the evidence required for such action by the indenture.

          If the indenture trustee resigns, is removed or becomes incapable of acting, or if a vacancy occurs in the office of the indenture trustee for any reason, the trust shall promptly appoint a successor indenture trustee. If, within one year after such resignation, removal or incapability or the occurrence of such vacancy, a successor indenture trustee shall be appointed by holders of notes representing a majority in aggregate principal amount of the outstanding notes of the applicable series delivered to the trust and the retiring indenture trustee, the successor indenture trustee so appointed shall, upon its acceptance of such appointment, become the successor indenture trustee and supersede the successor indenture trustee appointed by the trust.

          The indenture trustee and each successor indenture trustee must be a United States person within the meaning of section 7701(a)(30) of the Code.

          With respect to any series of notes as to which affiliates of the indenture trustee will serve as Agent, the relevant trust will appoint an eligible and unauthorized entity to serve as indenture trustee with respect to such series of notes, instead of the indenture trustee.

          Citibank, N.A., in its capacities as indenture trustee, paying agent, registrar, transfer agent and calculation agent under each indenture, will act as servicer under the program.

Meetings of Holders

          A meeting of holders of notes of the applicable series may be called at any time and from time to time pursuant to the indenture to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by the indenture to be made, given or taken by such holders of such series of notes.

          Unless otherwise provided in the notes of the applicable series, the indenture trustee may at any time call a meeting of holders of notes of the applicable series for any purpose specified in the preceding paragraph, to be held at such time and at such place in The City of New York or at such other place as the indenture trustee shall determine. Notice of every meeting of such holders of notes of the applicable series, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, must be given not less than 21 nor more than 180 days prior to the date fixed for the meeting.

          Subject to the provisions under “— Modification and Amendments” above and Section 316 of the Trust Indenture Act of 1939, as amended, any resolution passed or decision taken at any meeting of holders of notes of the applicable series duly held in accordance with the indenture will be binding on all of the holders of notes of the applicable series, whether or not such holders were present or represented at the meeting.

Nonrecourse Enforcement

          Notwithstanding anything to the contrary contained in the indenture or the notes, other than as described below, none of us, PFG, our or its officers, directors, affiliates, employees or agents, the trust and none of its trustees, beneficial owners (including the trust beneficial owner) or agents, or any of their respective officers, directors, affiliates, employees or agents, all of whom we refer to collectively in this prospectus and the accompanying prospectus supplement as the “nonrecourse parties,” will be personally liable for the payment of any principal, interest or any other sums at any time owing under the terms of any notes. If any Event of Default shall occur with respect to a series of notes, the right of the holder(s) of the notes of such series and the indenture trustee on behalf of such holder(s) in connection with a claim on such series of notes will be limited solely to a proceeding against the collateral for such series of notes.

          Neither such holder(s) nor the indenture trustee on behalf of such holder(s) will have the right to proceed against the nonrecourse parties or the assets of any other trust to enforce the relevant series of notes (except that to the extent they exercise their rights, if any, to seize the funding agreement and the

related guarantee securing the notes held by such holder(s), they may enforce the funding agreement against us or the related guarantee against PFG) or for any deficiency judgment remaining after foreclosure of any property included in the collateral. However, this will not in any manner or way constitute or be deemed a release of the debt or other obligations evidenced by the notes or otherwise affect or impair the enforceability against the assets of the relevant trust of the collateral or any other instrument or agreement evidencing, securing or relating to the indebtedness or the obligations evidenced by the notes. The holders of notes are not precluded from foreclosing upon any property included in the collateral.

Enforcement of Rights Under Securities Law

          Since we and PFG are registrants, purchasers of notes may proceed directly against us and PFG to enforce their rights under the United States federal and state securities laws. The right by such purchasers to proceed against us, with respect to the applicable funding agreement, under the United States federal and state securities laws is no different than if we had issued the funding agreement directly to such purchasers. The right by such purchasers to proceed against PFG, with respect to the applicable guarantee, under the United States federal and state securities laws is no different than if PFG had issued the guarantee directly to such purchasers.

Miscellaneous

          All notices regarding notes may be sent by overnight courier or first class mail (or equivalent) or (if posted to an overseas address) by airmail, postage prepaid, to the registered owners of the notes as their names appear in the note register maintained by the registrar or, for book-entry notes, notice may be given to The Depository Trust Company for communication by it to its accountholders or by delivery.

          The indenture and the notes of each series shall be governed by, and construed in accordance with, the laws of the State of New York, except to the extent that the validity or perfection of the ownership of and security interest in the relevant funding agreement and the related guarantee of the relevant trust or remedies under the indenture in respect thereof may be governed by the laws of a jurisdiction other than the State of New York. All judicial proceedings brought against the trust or the indenture trustee arising out of or relating to the indenture, any note or any portion of the collateral may be brought in a United States federal court of competent jurisdiction located in New York City, the Borough of Manhattan, provided that the pricing supplement for any series of notes may specify other jurisdictions as to which the trust may consent to the nonexclusive jurisdiction of its courts with respect to such series of notes.

DESCRIPTION OF THE FUNDING AGREEMENTS

          This section provides a summary of the material terms and conditions of the funding agreements. Specific terms of a funding agreement issued with respect to a series of notes and the extent to which these general provisions apply to that funding agreement will be provided in the applicable prospectus supplement and pricing supplement to this prospectus. This summary is not complete and you should read the detailed provisions of the funding agreement. A form of the funding agreement is filed as an exhibit to the registration statement (of which this prospectus is a part) and is incorporated into this prospectus by reference.

General

          Each funding agreement will be issued by us to the applicable trust and will be held separately as collateral by the indenture trustee for the benefit of the holders of the related series of notes. Each funding

agreement will represent our unsecured obligation. Under each funding agreement, the applicable trust shall pay us a deposit in an amount equal to the issue price (expressed as a percentage) of the notes multiplied by the aggregate principal amount of the series of notes plus the aggregate amount of the trust beneficial interest issued in connection with such funding agreement plus accrued interest, if any, less any commission or compensation payments due to any person. Such deposit shall be made in the currency in which such notes are denominated. Upon receipt of such deposit we shall then be obligated to establish a bookkeeping account which will evidence our obligation under the funding agreement. Unless otherwise specified in the applicable pricing supplement, the initial deposit of such obligation will be deemed to be equal to the aggregate face amount of the notes of such series of notes plus the aggregate amount of the trust beneficial interest and interest, if any, will accrue on such balance at such rate and upon such terms as is accruing on the applicable series of notes. Unless otherwise specified in the applicable pricing supplement, for a funding agreement securing a series of notes other than discount notes, the aggregate of the deposits received pursuant to the funding agreement (as specified in the applicable annex to such funding agreement), less any withdrawals to make payments under such funding agreement (other than additional amounts, if applicable), plus any interest accrued pursuant to such funding agreement, all as set forth in the applicable annex to such funding agreement, is referred to as the “fund.” Unless otherwise specified in the applicable pricing supplement, for a funding agreement securing a series of notes that are discount notes, the aggregate of the deposits received pursuant to the funding agreement (as specified in the applicable annex to such funding agreement), less any withdrawals to make payments under such funding agreement (other than additional amounts, if applicable), plus any accrual of discount (determined in accordance with the applicable series of notes), plus, if applicable, any interest accrued pursuant to such funding agreement, all as set forth in the applicable annex to such funding agreement, is referred to as the “fund.” The bookkeeping account established to evidence the fund is a general account obligation and shall not be an obligation of any of our separate accounts.

          Under each funding agreement, we will be obligated to make or cause to be made certain payments as are necessary to permit the trust to meet in full its scheduled payment obligations under the relevant series of notes. Therefore, the currency of denomination, maturity, redemption, repayment and interest rate provisions of the funding agreement issued by us to the trust shall be structured so that the payments made by or at the direction of us will enable the trust to meet its requisite obligations under the relevant series of notes. The repayment of principal on such funding agreement will occur at the stated date of maturity of the funding agreement, or, under certain circumstances specified by the terms of the funding agreement, at a date or dates prior to maturity. Amounts received by a trust in respect of interest or principal on a funding agreement will be applied to all payments due the holders of notes of the related series of notes and beneficial interest for that trust. Each funding agreement provides that all such payments are intended to be made without any United States tax withholding obligations. Any amendment or modification to the terms of a series of notes made after the effective date of the relevant funding agreement will not affect our payment obligations pursuant to the relevant funding agreement, unless such amendment or modification has been consented to in writing by us. Additional terms of each funding agreement will be described in the applicable prospectus supplement and pricing supplement.

          A funding agreement is a type of insurance company product in which the purchaser, usually an institutional investor, pays the insurance company a deposit and, in turn, receives scheduled payments of principal and interest. The deposit we receive on the issuance of a funding agreement will be part of our general account and not allocated to any of our separate accounts. Our general account is the account which contains all of our assets and liabilities other than those held in our separate accounts. (Separate accounts are segregated accounts which are established for certain products that we sell. A separate account holds assets and liabilities specifically related to one or more products and segregates these assets and liabilities from the assets and liabilities of all other separate accounts and the assets and liabilities of our general account.) Since the deposit made under any funding agreement will be part of our general account, our obligations under each funding agreement will be the obligations of our general account, rather than the obligations of any separate account. As such, we will invest the proceeds from the sale of funding agreements in a portfolio of assets which along with our other general account assets will be used to meet our contractual obligations under the funding agreements and our other general account

obligations. We will earn the spread differential between the cost of our obligations under the funding agreements and the yield on our invested assets. We may periodically, consistent with our past practice and subject to all applicable regulatory restrictions on our insurance operations, dividend a portion of the spread income to PFG.

          We have established internal procedures to ensure that we perform all of our payment obligations under the funding agreements. A specific group of employees in our company will monitor performance of our payment obligations under the funding agreements and will promptly notify the indenture trustee in the event we have not timely made payments under any funding agreement. Under the applicable indenture, the calculation agent will notify us of the amount of interest due on any notes prior to any interest payment date. Additionally, in the event that we fail timely to make any payment under the applicable funding agreement and PFG fails timely to make any payment under the related guarantee, the indenture trustee will notify us and PFG of such failure and will have the right to enforce the rights of noteholders contained in the indenture.

          Unless otherwise set forth in the applicable pricing supplement, the funding agreements will be rated AA by Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc. We expect the funding agreements to be rated Aa2 by Moody’s Investors Service, Inc. (“Moody’s”). The rating of the applicable funding agreement by Moody’s will be specified in the applicable pricing supplement. Notes of a series will be issued only in the event that, at the time of issuance of such series of notes, at least one nationally recognized rating agency would assign an investment grade rating to such series of notes and the funding agreement securing such series of notes.

          The trust will grant a security interest in and collaterally assign the funding agreement relating to the applicable series of notes to the indenture trustee as collateral to secure the trust’s obligations under that series of notes.

Priority

          Each funding agreement is our unsecured obligation and, in the event of our impairment or insolvency, the Iowa Insurance Commissioner will be authorized and directed to commence delinquency proceedings for the purpose of liquidating, rehabilitating, reorganizing or conserving us pursuant to Iowa Code Sections 507C.4, 507C.12, 507C.13, 507C.14 and 507C.16. In conducting delinquency proceedings, claims are prioritized and an order of distribution is specified pursuant to Iowa Code Section 507C.42. There are nine classes within the priority scheme, with each successive class being fully junior to the preceding class. Class 1 priority is given to the costs and expenses of administration of the insurer during the delinquency proceedings and Class 2 priority is given to the claims of the insurer’s policyholders and guaranty associations. Sidley Austin LLP, counsel to us and PFG, has opined that, subject to the limitations, qualifications and assumptions set forth in its opinion letter, in a properly prepared and presented case, a court applying Iowa law would conclude that loss claims of principal and interest in respect of each funding agreement would be accorded Class 2 priority under Iowa Code Section 507C.42 and paid equally in priority with our other policyholders.

          Sidley Austin LLP has advised that its opinion is based on its interpretation of the relevant provisions of the Iowa Code as construed by relevant administrative and judicial authority. However, the Iowa Code and regulations, interpretations and decisions are subject to change, either prospectively or retroactively, and many of the issues addressed in counsel’s opinion depend upon a facts and circumstances analysis that has received little or no administrative or judicial consideration. Therefore, the Iowa Insurance Commissioner, in his/her capacity as liquidator, rehabilitator or otherwise, or the courts could disagree in whole or in part with our analysis.

          Iowa law would apply to our insolvency or receivership proceedings. Sidley Austin LLP has advised that the statutory liquidation priority accorded to funding agreements under Iowa law does not clearly apply to any additional amounts required to be paid (if specified in the applicable pricing supplement) as may be necessary in order that the net amounts receivable by a holder after any withholding or deduction under United States tax law shall equal the respective amounts which would

have been receivable by such holder in the absence of such withholding or deduction. Accordingly, Sidley Austin LLP has advised that claims for such payments, if any, may not rank equally with either life insurance policy and annuity claims or funding agreement claims, but would rank at least equally with the claims of our general creditors, which are given Class 5 priority under Iowa Code Section 507C.42. Sidley Austin LLP expressly disclaimed any opinion that claims for such payments would be entitled to any greater priority.

          The scope of the Sidley Austin LLP opinion regarding a delinquency proceeding with respect to Principal Life is limited to an Iowa delinquency proceeding under Iowa law and to only those claims that are made in domiciliary proceedings in an Iowa court. The opinion of Sidley Austin LLP recites basic facts with respect to the transaction in which the funding agreement is to be issued, and those facts are implicitly assumed in connection with the rendering of the opinion. The limitations and qualifications in the opinion are that it is limited to the application of the law of the State of Iowa and federal law of the United States and that the opinion is rendered solely as of the date thereof.

          In the event that the funding agreements were not accorded Class 2 priority in our insolvency, the funding agreements would be accorded the lower priority associated with our general unsecured obligations. Our payment obligations under the funding agreements are fully and unconditionally guaranteed by PFG. See “Description of the Guarantees.”

Funding Agreement Events of Default

          Each of the following events will constitute an event of default (a “funding agreement default”) under each funding agreement:

          Upon the occurrence and continuance of a funding agreement default specified in the first or second bullet point above, the indenture trustee (as collateral holder) has the right, in addition to any other rights and remedies they may have at law or in equity, to immediately demand payment of all principal and accrued and unpaid interest and any other amount due to such date under the affected funding agreement. Upon the occurrence of a funding agreement default specified in the third bullet point above, the principal of and accrued and unpaid interest and any other amounts payable under the affected funding agreement will be immediately due and payable without any declaration or other action by the trust or the indenture trustee (as collateral holder).

Optional Redemption; Optional Repayment

          If a redemption right is specified in the pricing supplement related to a series of notes, we may redeem the related funding agreement prior to the stated maturity date of such funding agreement in whole or from time to time in part in increments of $1,000 or any other integral multiple of an authorized denomination specified in the applicable pricing supplement (provided that any remaining principal amount thereof shall be at least $1,000 or other minimum authorized denomination applicable thereto), at the applicable redemption price (as defined below), together with unpaid interest, if any, accrued thereon to, but excluding, the date of redemption. We must give written notice to the trust not more than 60 nor less than 35 calendar days prior to the date of redemption. “Redemption price”, with respect to a funding agreement, means an amount equal to the initial redemption percentage specified in the applicable pricing supplement (as adjusted by the annual redemption percentage reduction, as described in the pricing supplement, if applicable) multiplied by the unpaid principal amount to be redeemed. The initial redemption percentage, if any, applicable to a funding agreement shall decline at each anniversary of the initial redemption date by an amount equal to the applicable annual redemption percentage reduction, if any, until the redemption price is equal to 100% of the unpaid amount thereof to be redeemed.

          If a repayment right is specified in the pricing supplement relating to a series of notes, the related funding agreement may be subject to repayment at the request of the relevant trust, upon the valid exercise of the repayment right in the related notes by the holder of such notes, on any repayment date specified in the applicable pricing supplement. On any such repayment date, unless otherwise specified in the applicable pricing supplement, the funding agreement shall be repayable in whole or in part in increments of $1,000 at the request of the relevant trust at a repayment price equal to 100% of the principal amount thereof to be repaid, together with interest thereon payable to the date of repayment. Exercise of such repayment right by a trust shall be irrevocable.

Survivor’s Option

          Unless a funding agreement has been declared due and payable prior to its stated maturity date by reason of any event of default thereunder, or has been previously redeemed or otherwise repaid, a trust may request repayment of such funding agreement upon the valid exercise of the survivor’s option in the related notes by the authorized representative of the deceased beneficial owner of such notes. If a survivor’s option is specified in the notes and the applicable pricing supplement it will be more fully described in the prospectus supplement relating to such notes.

Withholding Tax and Payment of Additional Amounts

          All amounts due in respect of each funding agreement will be made without withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of any governmental authority, unless such withholding or deduction is required by law. Unless otherwise specified in the applicable

pricing supplement, we will not pay any additional amounts to the trust in respect of such withholding or deduction, any such withholding or deduction will not give rise to any funding agreement default or any independent right or obligation to redeem such funding agreement and the trust will be deemed for all purposes to have received cash in an amount equal to the portion of such withholding or deduction that is attributable to such trust’s interest in the funding agreement as equitably determined by us.

          If it is specified in the applicable pricing supplement and funding agreement that we have agreed to pay additional amounts to the trust to reflect any required withholding or deduction under the funding agreement and we are required, or based on an opinion of independent legal counsel selected by us a material probability exists that we will be required, to pay additional amounts in respect of such withholding or deduction, pursuant to (a) any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein or (b) any amendment to, or change in, an interpretation or application of any such laws or regulations by any governmental authority in the United States, which amendment or change is enacted, promulgated, issued or announced on or after the effective date of the applicable funding agreement, we will have the right to redeem the affected funding agreement by giving not less than 30 and no more than 60 days prior written notice to the trust and by paying to the trust the outstanding principal of, and premium, if any, and accrued but unpaid interest, on, the relevant funding agreement or such other amount as is specified in the applicable pricing supplement. If we redeem the related funding agreement issued to the trust, the related trust will redeem all of the notes of the applicable series as provided in the indenture.

Early Redemption for Tax Event

          Each funding agreement will provide that, upon the occurrence of a tax event (as described below), we may redeem such funding agreement by giving not less than 35 and no more than 60 calendar days prior written notice to the applicable trust and by paying to such trust the outstanding principal of, and premium, if any, and accrued but unpaid interest, on, the relevant funding agreement or such other amount as is specified in the applicable pricing supplement. If we redeem a funding agreement, the applicable trust will redeem all of the notes of the series secured by such funding agreement as provided in the indenture. The term “tax event” means that we shall have received an opinion of independent legal counsel stating in effect that as a result of (a) any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein or (b) any amendment to, or change in, an interpretation or application of any such laws or regulations by any governmental authority in the United States, which amendment or change is enacted, promulgated, issued or announced on or after the effective date of the funding agreement there is more than an insubstantial risk that (i) the trust is, or will be within 90 days of the date thereof, subject to United States federal income tax with respect to interest accrued or received on the relevant funding agreement or (ii) the trust is, or will be within 90 days of the date thereof, subject to more than a de minimis amount of taxes, duties or other governmental charges.

Restrictions on Transfer

          Each funding agreement will contain provisions prohibiting the owner of the funding agreement from transferring or assigning the funding agreement or any right to receive payments under the funding agreement to any other person without our express written consent. In connection with the issuance of a series of notes by the trust, we will consent to the assignment of the related funding agreement that will secure the obligations of the issuer trust under such notes to the indenture trustee.

Agreed Tax Treatment

          We and the trust will agree that each funding agreement shall be disregarded for United States federal income tax purposes. The funding agreement will provide that we and the applicable trust each agree to treat the funding agreement, if not disregarded for United States federal income tax purposes, as a debt obligation of ours for United States federal, state and local income and franchise tax purposes.

Governing Law

          Each funding agreement will be subject to the laws of the State of Iowa.

DESCRIPTION OF THE GUARANTEES

          Set forth below is a summary of the guarantee that will be issued by PFG to each trust in connection with each issuance of a series of notes. This summary is not complete and you should read the detailed provisions of the guarantee. A form of the guarantee is filed as an exhibit to the registration statement (of which this prospectus forms a part) and is incorporated into this prospectus by reference.

General

          Under each guarantee, PFG will fully, irrevocably, absolutely and unconditionally guarantee to pay to the trust any payments required to be made by us to the trust under the applicable funding agreement which shall become due and payable regardless of whether such payment is due at maturity, on an interest payment date or as a result of redemption or otherwise (the “scheduled payments”) but shall be unpaid by us (the “guaranteed amounts”). However, in no event shall the guaranteed amounts under a guarantee exceed the deposit of the related funding agreement, plus accrued but unpaid interest and any other amounts due and owing under the funding agreement, less any amounts paid by us to the applicable trust.

          In the event we do not make a scheduled payment when due (the “payment notice date”) then the indenture trustee or the trust may present a payment notice in writing to PFG on or after the payment notice date, and PFG will be required to immediately pay the guaranteed amounts.

          The trust will collaterally assign and grant a security interest in the guarantee to the indenture trustee as collateral to secure the trust’s obligations under the applicable series of notes.

          Each guarantee will be an unsecured, unsubordinated and contingent obligation of PFG ranking equally with all other unsecured and unsubordinated obligations of PFG. PFG is a non-operating holding company, conducting a substantial portion of its business through us. In the event of our insolvency or receivership, PFG may incur limitations in receiving any distributions from us. In such an event, PFG may have limited resources to satisfy its obligations under the guarantees. PFG’s obligations under each guarantee will be effectively subordinated to all existing and future debt and liabilities of PFG’s subsidiaries.

Events of Default

          An event of default under each guarantee will occur upon the failure of PFG to perform any of its payment obligations thereunder. The trust and the indenture trustee, on behalf of the holders of the applicable series of notes, have the right to enforce the obligations of PFG under the applicable guarantee and may institute any legal proceeding directly against PFG without first instituting a legal proceeding against us. Bankruptcy or similar events relating to PFG, the failure of any guarantee to be in full force and effect and any revocation of any guarantee by PFG will not constitute events of default under such guarantee.

Termination of the Guarantee

          Each guarantee will terminate and be of no further force and effect with respect to the applicable funding agreement upon the full payment of the scheduled payments or upon the earlier extinguishment of our obligations under the relevant funding agreement.

Governing Law

          Each guarantee will be governed by, and construed in accordance with, the laws of the State of New York without regard to conflict of law principles.

FEES AND EXPENSES

          All expenses of the program will be paid pursuant to the separate expense and indemnity agreements entered into between us and the indenture trustee, the custodian, the trust beneficial owner and the trustee (on behalf of itself and each trust to be formed in connection with the issuance of a series of notes) and each expense and indemnity agreement to be entered into with each service provider that may become a provider of services under the programs from time to time. A form of each expense and indemnity agreement have been filed as exhibits to the registration statement (which includes this prospectus) and are incorporated into this prospectus by reference.

          Pursuant to each expense and indemnity agreement, we will pay the costs and expenses relating to the offering, sale and issuance of any series of notes and costs, expenses and taxes incurred by each trust other than certain excluded amounts described below and we will pay the costs and expenses of the indenture trustee, the custodian, the trust beneficial owner, the trustee, each trust and each service provider appointed from time to time and will indemnify each of them with respect to certain matters.

          Under each expense and indemnity agreement, we will not be obligated to pay any costs, expenses, taxes or other amounts that are considered excluded amounts. Excluded amounts include:

          Each expense and indemnity agreement will be governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of laws principles.

          Additionally, under certain circumstances to the extent not paid pursuant to the applicable expense and indemnity agreement, the indenture trustee, the custodian, the trust beneficial owner, the

trustee and any service provider appointed from time to time may be paid out of the trust’s assets as described in the table below:

ERISA CONSIDERATIONS

          The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), imposes certain requirements on “employee benefit plans” (as defined in Section 3(3) of ERISA) subject to ERISA, including entities such as collective investment funds whose underlying assets include the assets of such plans (collectively, “ERISA plans”), and on those persons who are fiduciaries with respect to ERISA plans. Investments by ERISA plans are subject to ERISA’s general fiduciary requirements, including the requirement of investment prudence and diversification and the requirement that an ERISA plan’s investments be made in accordance with the documents governing the ERISA plan. Each fiduciary of an ERISA plan should consider the fiduciary standards of ERISA in the context of the ERISA plan’s particular circumstances before authorizing an investment in the notes. Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing the ERISA plan.

          Subject to the considerations described herein, the notes are eligible for purchase by plans, any entity whose underlying assets include “plan assets” by reason of any plan’s investment in the entity (“plan asset entity”) and any person investing “plan assets” of any plan.

          Under United States Department of Labor regulations at 29 C.F.R. § 2510.3-101, as in effect from time to time (the “plan asset regulations”), the assets of a trust may be deemed to be “plan assets” of an ERISA plan or a “plan” such as an individual retirement account or a Keogh plan (as defined in Section 4975(e)(1) of the Code, other than a governmental or church plan described in Section 4975(g)(2) or (3) of the Code) (together with ERISA plans, “plans”) for purposes of ERISA and Section 4975 of the Code if a plan or a person investing “plan assets” of a plan acquires an equity interest in a trust and none of the exceptions contained in the plan asset regulations are applicable. An equity

interest is defined under the plan asset regulations as any interest in an entity other than an instrument that is treated as indebtedness under applicable local law and has no substantial equity features. There is very little pertinent authority on the issue of what constitutes an equity interest for purposes of the plan asset regulations. Accordingly, whether the notes would be treated as debt or equity for purposes of the plan asset regulations is unclear. Since, however, the holders of notes of a series will have recourse only to the relevant collateral that secures such series of notes, if the notes were treated as equity interests, only the related funding agreement would be treated as assets of any plan holding a note.

          Even if the notes are treated as equity interests for purposes of the plan asset regulations, because (a) the relevant trust expects that the funding agreement will be treated as debt, rather than equity, for United States federal tax purposes and (b) the funding agreement should not be deemed to have any “substantial equity features,” none of the assets underlying the funding agreement should be treated as “plan assets” for purposes of the plan asset regulations. Those conclusions are based, in part, upon the traditional debt features of the funding agreement, including the reasonable expectation of purchasers of the notes that the payments due under the funding agreement will be paid when due, as well as the absence of conversion rights, warrants and other typical equity features.

          Section 406 of ERISA and Section 4975 of the Code prohibit plans from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to such plans (together, “parties in interest”), unless a statutory or administrative exemption is available. For example, if we, a trust or any Agent are a party in interest with respect to a plan (either directly or by reason of our ownership of subsidiaries), the purchase of the notes by or on behalf of the plan would likely be a prohibited transaction under Section 406(a)(1) of ERISA and Section 4975(c)(1) of the Code, unless exemptive relief were available under an applicable administrative exemption (see below). A party in interest that engages in a prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code, unless a statutory or administrative exemption is available.

          The United States Department of Labor (“DOL”) has issued prohibited transaction class exemptions (“PTCEs”) that may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase and holding of the notes by or on behalf of a plan. These class exemptions include PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers). There can be no assurances that any of these class exemptions or any other exemptions will be available with respect to any particular transaction involving the notes. In addition, a purchaser of the notes should be aware that, even if the conditions specified in one or more of the above-referenced exemptions are met, the scope of the exemptive relief provided by the exemption might not cover all acts which might be construed as prohibited transactions.

          Accordingly, the notes may not be purchased or held by any plan, any plan asset entity or any person investing “plan assets” of any plan, unless the purchase and holding of the notes is not a prohibited transaction or is exempt under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or any other prohibited transaction exemption issued by the DOL. Any purchaser of the notes or any interest therein, including in the secondary market, will be deemed to have represented that, among other things, either it is not a plan or other plan asset entity and it is not purchasing the notes on behalf of or with “plan assets” of any plan or other plan asset entity, or its purchase and holding of the notes is exempt under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another applicable exemption. Such representations shall be deemed to be made each day from the date on which the purchaser purchases the notes through and including the date on which the purchaser disposes of the notes.

          Moreover, the notes may not be purchased or held by any plan, any plan asset entity or any person investing “plan assets” of any plan if we, the trust, the indenture trustee, the guarantor or any of their respective affiliates: (a) has investment discretion with respect to the assets of the plan used to effect

such purchase; (b) has authority or responsibility to give, or regularly give, investment advice with respect to such assets for a fee and pursuant to an agreement or understanding that such advice (1) will serve as a primary basis for investment decisions with respect to such assets and (2) will be based on the particular investment needs of such plan; or (c) unless PTCE 95-60, 91-38 or 90-1 applies, is an employer maintaining or contributing to such plan.

          Any insurance company proposing to invest assets of its general account in the notes should consider the implications of the United States Supreme Court’s decision in John Hancock Mutual Life Insurance Co. v. Harris Trust and Savings Bank, 510 U.S. 86, 114 S. Ct. 517 (1993), in which the United States Supreme Court held that in certain circumstances assets in a life insurance company’s general account are treated as assets of a plan that owns a policy or other contract with such insurance company, as well as the effect of Section 401(c) of ERISA as interpreted by regulations issued by the DOL in January 2000.

          Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing notes on behalf of or with “plan assets” of any plan or plan asset entity consult with their counsel regarding the potential consequences under ERISA and the Code and the availability of exemptive relief under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14.

          Governmental plans (as defined in Section 3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA), while not subject to the fiduciary responsibility provisions of ERISA or the provisions of Section 4975 of the Code, may nevertheless be subject to state, local or other federal laws that are substantially similar to the foregoing provisions of ERISA and the Code such as Section 503 of the Code. No view is expressed as to whether an investment in the notes (and any continued holding of the notes), or the operation and administration of the trust, is appropriate or permissible for any governmental plan or church plan under Section 503 of the Code, or under any state, local or other law respecting such plan. Any purchaser of the notes or any interest therein, including in the secondary market, will be deemed to have represented that, among other things, either (a) it is not a governmental plan or a church plan or any entity the assets of which are treated as including assets of such plans and it is not purchasing the notes on behalf of or with assets of any such plan or entity or (b) its purchase, holding and disposition of the notes is not in violation of the laws applicable to any such governmental plan or church plan. Such representations shall be deemed to be made each day from the date on which the purchaser purchases the notes through and including the date on which the purchaser disposes of the notes. Fiduciaries of any such plans should consult with their counsel before purchasing any notes.

          The sale of any notes to a plan is in no respect a representation by any party or entity that such an investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan.

          Notwithstanding the above, with regard to a particular trust, the sale of notes to plans, or a person utilizing the plan assets of plans, might not be allowed, or might only be allowed subject to certain additional conditions, in which case the applicable pricing supplement will disclose the prohibition or such additional conditions.

          THE ERISA CONSIDERATIONS SET FORTH ABOVE ARE ONLY INTENDED AS A SUMMARY AND MAY NOT BE APPLICABLE DEPENDING UPON A PLAN’S SPECIFIC FACTS AND CIRCUMSTANCES. PLAN FIDUCIARIES SHOULD CONSULT THEIR OWN ADVISORS WITH RESPECT TO THE ADVISABILITY OF AN INVESTMENT IN THE NOTES, AND POTENTIALLY ADVERSE CONSEQUENCES OF SUCH INVESTMENT, INCLUDING WITHOUT LIMITATION THE POSSIBLE EFFECTS OF CHANGES IN APPLICABLE LAWS.

The Agents may sell the notes to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the purchasers for whom they may act as agents. The Agents and dealers that participate in the distribution of the notes are “underwriters” within the meaning of the Securities Act of 1933, as amended, with respect to the notes being distributed, the funding agreement purchased by the trust and the guarantee issued to the trust.
