Unless otherwise noted, equity investments are common units/common shares.

Securities are categorized as “Midstream” if they (i) derive at least 50% of their revenues or operating income from operating Midstream Assets or (ii) have Midstream Assets that represent the majority of their assets.

On March 12, 2019, Antero Midstream GP LP (“AMGP”) and Antero Midstream Partners LP (“AM”) completed their previously announced merger whereby AMGP acquired all of the outstanding AM common units. In connection with the transaction, AMGP converted into a corporation and the combined entity was renamed Antero Midstream Corporation with its shares trading under the ticker symbol “AM”.

This company is structured like an MLP, but is not treated as a publicly-traded partnership for regulated investment company (“RIC”) qualification purposes.

The Fund’s ability to sell this security is subject to certain legal or contractual restrictions. As of February 28, 2019, the aggregate value of restricted securities held by the Fund was $68,906 (7.4% of total assets), which included $28,090 of Level 2 securities and $40,816 of Level 3 securities.

Fair valued security.

Class B Units are convertible on a one-for-one basis into common units of Capital Product Partners L.P. (“CPLP”) and are senior to the common units in terms of liquidation preference and priority of distributions (liquidation preference of $9.00 per unit). On March 27, 2019, CPLP and DSS Holdings L.P. (“DSS”) completed their previously announced combination whereby CPLP spun off its crude and product tanker business into a separate publicly listed company, which merged with DSS. In connection with this transaction, all of the Fund’s CPLP Class B Units were redeemed for cash at $9.00 per unit.

The Fund believes that it is an affiliate of Buckeye Partners, L.P. (“BPL”), Plains AAP, L.P. (“PAGP-AAP”) and Plains GP Holdings, L.P. (“PAGP”). The Fund does not believe that it is an affiliate of California Resources Corporation.

The Fund’s ownership of PAGP-AAP is exchangeable on a one-for-one basis into either PAGP shares or Plains All American Pipeline, L.P. (“PAA”) units at the Fund’s option. The Fund values its PAGP-AAP investment on an “as exchanged” basis based on the higher public market value of either PAGP or PAA. As of February 28, 2019, the Fund’s PAGP-AAP investment is valued at PAA’s closing price.

Unless otherwise noted, securities are treated as a publicly-traded partnership for RIC qualification purposes. To qualify as a RIC for tax purposes, the Fund may directly invest up to 25% of its total assets in equity and debt securities of entities treated as publicly-traded partnerships. The Fund had 24.1% of its total assets invested in publicly-traded partnerships at February 28, 2019. It is the Fund’s intention to be treated as a RIC for tax purposes.

On February 28, 2019, Western Gas Partners, LP (“WES”) and Western Gas Equity Partners, LP (“WGP”) completed their previously announced merger whereby WGP acquired all of the publicly - held common units of WES in a unit-for-unit exchange. Immediately following the merger, WGP changed its name to Western Midstream Partners, LP with its units trading under the ticker symbol “WES”.

On December 19, 2018, Jupiter Resources Inc. and its affiliates (“Jupiter”) completed a recapitalization transaction. As a result of the reorganization, the Fund received 1,261 common shares of Jupiter Resources Inc. and cash equal to the semi-annual interest payment that was scheduled to be paid on October 1, 2018. The common shares are not publicly traded and are subject to certain restrictions. As of October 2, 2018, the Fund stopped accruing interest relating to the debt security.

On February 28, 2019, Eclipse Resources Corporation (“Eclipse Resources”) and Blue Ridge Mountain Resources, Inc. (“Blue Ridge”) completed their previously announced merger. In conjunction with the merger, Eclipse Resources changed its name to Montage Resources Corporation.

The notional amount of call option contracts written is the product of (a) the number of contracts written, (b) 100 (each contract entitles the option holder to 100 units/shares) and (c) the market price of the underlying security as of February 28, 2019.

Security is non-income producing.
