U.S. SILICA HOLDINGS, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited; dollars in thousands, except per share amounts)
NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Consolidation
The accompanying Condensed Consolidated Financial Statements (the “Financial Statements”) of U.S. Silica Holdings, Inc. (“Holdings,” and together with its subsidiaries “we,” “us” or the “Company”) included in this Quarterly Report on Form 10-Q , have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission (“SEC”). They do not contain certain information included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014; therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K. In the opinion of management, all adjustments necessary for a fair presentation of the Financial Statements have been included. Such adjustments are of a normal, recurring nature. We have reclassified certain immaterial amounts in the prior years’ assets section of the consolidated balance sheets and operating activities section of the consolidated statement of cash flows to conform to the current year presentation. These reclassifications had no effect on previously reported total assets and net cash flows from operations.
In order to make this report easier to read, we refer throughout to (i) our Condensed Consolidated Balance Sheets as our “Balance Sheets,” (ii) our Condensed Consolidated Statements of Operations as our “Income Statements,” and (iii) our Condensed Consolidated Statements of Cash Flows as our “Cash Flows.”
Unaudited Interim Financial Statements
The accompanying Balance Sheet as of March 31, 2015; the Income Statements for the three months ended March 31, 2015 and 2014; the Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2015 and 2014; the Condensed Consolidated Statements of Stockholders' Equity for the three months ended March 31, 2015; the Cash Flows for the three months ended March 31, 2015 and 2014; and other information disclosed in the related notes are unaudited. The Balance Sheet as of December 31, 2014 was derived from our audited consolidated financial statements as included in our 2014 Annual Report.
Use of Estimates and Assumptions
The preparation of the Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations; environmental, reclamation and closure obligations; estimates of recoverable minerals; estimates of allowance for doubtful accounts; estimates of fair value for certain reporting units and asset impairments (including impairments of goodwill and other long-lived assets); write-downs of inventory to net realizable value; equity-based compensation expense; post-employment, post-retirement and other employee benefit liabilities; valuation allowances for deferred tax assets; reserves for contingencies and litigation; and the fair value and accounting treatment of financial instruments including derivative instruments. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates under different assumptions or conditions.
Recently Issued Accounting Pronouncements
In April 2015, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update, Interest-Imputation of Interest, which simplifies presentation of debt issuance costs. The new standard requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The new standard will be effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within fiscal years beginning after December 15, 2016. Early adoption of the amendments in this Update is permitted for financial statements that have not been previously issued. We have elected to adopt the standard early and have presented debt issuance costs as a direct deduction from the carrying amount of debt on our Balance Sheets as of March 31, 2015 and December 31, 2014.

NOTE B—EARNINGS PER SHARE
Basic earnings per common share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed similarly to basic income per common share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. In accordance with the applicable accounting guidance for calculating earnings per share, we did not include in our calculation of diluted earnings per share for the applicable periods stock options where the exercise prices were greater than the average market prices.

NOTE C—CAPITAL STRUCTURE AND ACCUMULATED COMPREHENSIVE INCOME
Common Stock
Our Amended and Restated Certificate of Incorporation, authorizes up to 500,000,000 shares of common stock, par value of $0.01. Subject to the rights of holders of any series of preferred stock, all of the voting power of the stockholders of Holdings shall be vested in the holders of the common stock. There were 53,374,963 shares of common stock issued and outstanding at March 31, 2015. As of March 31, 2014, there were 53,733,092 shares issued and outstanding.
In 2015, our Board of Directors declared quarterly cash dividends as follows:

February 12, 2015
 
March 16, 2015
 
April 3, 2015
All dividends were paid as scheduled.
Any determination to pay dividends and other distributions in cash, stock, or property by Holdings in the future will be at the discretion of our Board of Directors and will be dependent on then-existing conditions, including our business conditions, our financial condition, results of operations, liquidity, capital requirements, contractual restrictions including restrictive covenants contained in our debt agreements, and other factors. Additionally, because we are a holding company, our ability to pay dividends on our common stock may be limited by restrictions on the ability of our subsidiaries to pay dividends or make distributions to us, including restrictions under the terms of the agreements governing our indebtedness.
Preferred Stock
Our Amended and Restated Certificate of Incorporation authorizes our Board of Directors to issue up to 10,000,000 shares, in the aggregate, of preferred stock, par value of $0.01 in one or more series, to fix the powers, preferences and other rights of such series, and any qualifications, limitations or restrictions thereof, including the dividend rate, conversion rights, voting rights, redemption rights and liquidation preference, and to fix the number of shares to be included in any such series, without any further vote or action by our stockholders.
There are no shares of preferred stock issued or outstanding at March 31, 2015 and 2014. At present, we have no plans to issue any preferred stock.

8



Share Repurchase Program
We are authorized by our Board of Directors to repurchase shares of our outstanding common stock from time to time on the open market or in privately negotiated transactions. As of March 31, 2015, we are authorized to repurchase up to $50 million of our common stock through December 11, 2015. Stock repurchases, if any, will be funded using our available liquidity. The timing and amount of stock repurchases will depend on a variety of factors, including the market conditions as well as corporate and regulatory considerations. Under our share repurchase program, as of March 31, 2015, we have repurchased 706,093 shares of our common stock at an average price of $23.83 and are authorized to repurchase up to an additional $33.2 million of our common stock.
Accumulated Other Comprehensive Income
Accumulated other comprehensive income (loss) consists of fair value adjustments associated with cash flow hedges and accumulated adjustments for net experience losses and prior service cost related to employee benefit plans. The following table presents the changes in accumulated other comprehensive income by component during the three months ended March 31, 2015:

NOTE D—BUSINESS COMBINATIONS
On July 31, 2014, we completed our acquisition of Cadre Services, Inc. ("Cadre"), a regional sand mining company based in Voca, Texas, for approximately $98.3 million in cash.
The acquisition of Cadre resulted in goodwill of approximately $0.2 million, none of which is deductible for tax purposes. This amount represents the residual amount of the total purchase price after allocation to the assets acquired and liabilities assumed.

Our senior secured credit facility is secured by substantially all of our assets and a pledge of the equity interests in certain of our subsidiaries. The facility contains covenants that, among other things, govern our ability to create, incur or assume indebtedness and liens, to make acquisitions or investments, to pay dividends and to sell assets. The facility also requires us to maintain a consolidated total net leverage ratio of no more than 3.75:1.00 as of the last day of any fiscal quarter whenever usage of the Revolver (other than certain undrawn letters of credit) exceeds 25% of the Revolver commitment. As of March 31, 2015, we are in compliance with all covenants in accordance with our senior secured credit facility.
NOTE I—ASSET RETIREMENT OBLIGATIONS
Mine reclamation costs, or future remediation costs for inactive mines, are accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such cost estimates include, where applicable, ongoing care, maintenance and monitoring costs. Changes in estimates at inactive mines are reflected in earnings in the period an estimate is revised.
As of March 31, 2015 and December 31, 2014, we had recorded a liability of $11.5 million and $11.3 million in other long-term obligations related to our asset retirement obligation. Changes in the asset retirement obligation during the three months ended March 31, 2015 and the year ended December 31, 2014, respectively, are as follows:

NOTE J—FAIR VALUE ACCOUNTING
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quote prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3—Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.
Cash equivalents
Due to the short-term maturity, we believe our cash equivalent instruments at March 31, 2015 and December 31, 2014 approximate their reported carrying values.
Short-Term Investments
In general, the fair value of our short-term investments is based on quoted prices for similar assets in active markets, or for identical assets or similar assets in markets in which there were fewer transactions (Level 2). Money market mutual funds are based on calculated net asset value and are reported in Level 1. Variable rate demand obligations underwritten and remarketed by a financial institution are priced at par value.
Long-Term Debt, including current maturities
We believe that the fair values of our long-term debt, including current maturities, approximates their carrying values based on their effective interest rates compared to current market rates.
Derivative Instruments
The estimated fair value of our derivative assets (interest rate caps) are recorded at each reporting period and are based upon widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We also incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk as well as that of the respective counterparty in the fair value measurements.
Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default of ourselves and our counterparties. However, as of March 31, 2015, we have assessed that the impact of the credit valuation adjustments on the overall valuation of our derivative positions is not significant. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
In accordance with the fair value hierarchy, the following table presents the fair value as of March 31, 2015 of those assets that we measure at fair value on a recurring basis:

As of March 31, 2015, we considered the declines in market value of our short-term investment portfolio to be temporary in nature and did not consider any of our investments other-than-temporarily impaired. We typically invest in highly-rated securities, and our investment policy generally limits the amount of credit exposure to any one issuer. The policy requires investments generally to be investment grade, with the primary objective of minimizing the potential risk of principal loss. Fair values were determined for each individual security in the investment portfolio. When evaluating an investment for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates, and our intent to sell, or whether it is more likely than not it will be required to sell, the investment before recovery of the investment’s cost basis. As of March 31, 2015, we did not recognize any impairment charges.

Operating Leases
We are obligated under certain operating leases for railroad cars, office space, mining property, mining/processing equipment and transportation and other equipment. Certain operating lease agreements include options to purchase the equipment for fair market value at the end of the original lease term. In general, the above leases include renewal options and provide that we pay for all utilities, insurance, taxes and maintenance. Expense related to operating leases and rental agreements totaled approximately $10.0 million and $7.1 million for the three months ended March 31, 2015 and 2014, respectively. As of March 31, 2015, we have no obligations under a capital lease.
Minimum Purchase Commitments
We enter into service agreements with our transload service providers and transportation service providers. Some of these agreements require us to purchase a minimum amount of services over a specific period of time. Any inability to meet these

14



minimum contract requirements requires us to pay a shortfall fee, which is based on the difference between the minimum amount contracted for and the actual amount purchased.
Other Commitments and Contingencies
Our operating subsidiary, U.S. Silica Company (“U.S. Silica”), has been named as a defendant in various product liability claims alleging silica exposure causing silicosis. During the three months ended March 31, 2015, no new claims were brought against U.S. Silica. As of March 31, 2015, there were 75 active silica-related products liability claims pending in which U.S. Silica is a defendant. Although the outcomes of these claims cannot be predicted with certainty, in the opinion of management, it is not reasonably possible that the ultimate resolution of these matters will have a material adverse effect on our financial position or results of operations that exceeds the accrual amounts.
For periods prior to 1986, U.S. Silica had numerous insurance policies and an indemnity from a former owner that covered silicosis claims. In the fourth quarter of 2012, U.S. Silica settled all rights under the indemnity and its underlying insurance. The settlement was received during the first quarter of 2013. As a result of the settlement, the indemnity and related policies are no longer available to U.S. Silica and U.S. Silica will not seek reimbursement for any defense costs or claim payments. Other insurance policies, however, continue to remain available to U.S. Silica.
We have recorded estimated liabilities for these claims in other long-term obligations as well as estimated recoveries under the indemnity agreement and an estimate of future recoveries under insurance in other assets on our consolidated balance sheets. As of both March 31, 2015, and December 31, 2014 other non-current assets included $311 for insurance for third-party products liability claims and other long-term obligations included $1.6 million in third-party products claims liability.
Additionally, we recently received an unfavorable ruling in an arbitration proceeding as a result of exiting a toll manufacturing contract. The amount of the ruling was approximately $7.6 million, which was fully accrued as selling, general and administrative expense in our Income Statement for the three months ended March 31, 2015. We have filed an appeal with the arbitration panel in this matter and intend to vigorously pursue all other legal actions available to us.
NOTE M—INCOME TAXES
For interim period reporting, we record income taxes using an estimated annual effective tax rate based upon projected annual income, forecasted permanent tax differences, discrete items and statutory rates in states in which we operate. At the end of each interim period, we update the estimated annual effective tax rate, and if the estimated tax rate changes based on new information, we make a cumulative adjustment in the period. We record the tax effect of an unusual or infrequently occurring item in the interim period in which it occurs as a discrete item of tax.
In the three months ended March 31, 2015, we recorded a discrete tax benefit of $2.9 million, which relates to the accrual of approximately $7.6 million as described in Note L - Commitments and Contingencies.
The effective tax rates were 19% and 25% for the three months ended March 31, 2015 and March 31, 2014, respectively. The tax rate for the three months ending March 31, 2015 would have been 25% without the discrete tax benefit.
Historically, our actual effective tax rates have been lower than the statutory effective rate primarily due to the benefit received from statutory percentage depletion allowances. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income before income taxes.
NOTE N—PENSION AND POST-RETIREMENT BENEFITS
We maintain a single-employer noncontributory defined benefit pension plan covering certain employees. Net pension benefit cost recognized for the three months ended March 31, 2015 and 2014 are as follows:

For the three months ended March 31, 2015, we made no contributions to the qualified pension plan and made $0.8 million in contributions during the three months ended March 31, 2014. Total expected employer funding contributions during the fiscal year ending December 31, 2015 are $1.7 million for the pension plan and $1.7 million for the post-retirement medical and life plan.
NOTE O—OBLIGATIONS UNDER GUARANTEES
We have indemnified Travelers Casualty and Surety Company of America (“Travelers”) against any loss Travelers may incur in the event that holders of surety bonds, issued on behalf of us by Travelers, execute the bonds. As of March 31, 2015, Travelers had $8.5 million in bonds outstanding for us. The majority of these bonds, $8.2 million, relate to reclamation requirements issued by various governmental authorities. Reclamation bonds remain outstanding until the mining area is reclaimed and the authority issues a formal release. The remaining bonds relate to such indefinite purposes as licenses, permits, and tax collection.
U.S. Silica is the contingent guarantor of Kanawha Rail Corporation’s (“KRC”) obligations as lessee of 199 covered hopper railroad cars, which are used by U.S. Silica to ship sand to its customers. KRC’s obligation as lessee includes paying monthly rent of $66 thousand until June 30, 2015, maintaining the cars, paying for any cars damaged or destroyed, and indemnifying all other parties to the lease transaction against liabilities including any loss of certain tax benefits. By separate agreement between U.S. Silica and KRC, KRC may, upon the occurrence of certain events, assign the lease obligations to U.S. Silica, but none of these events have occurred.
NOTE P—SEGMENT REPORTING
Our business is organized into two reportable segments, Oil & Gas Proppants and Industrial & Specialty Products, based on end markets. The reportable segments are consistent with how management views the markets that we serve and the financial information reviewed by the chief operating decision maker. We manage our Oil & Gas Proppants and Industrial & Specialty Products businesses as components of an enterprise for which separate information is available and is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance.
An operating segment’s performance is primarily evaluated based on segment contribution margin, which excludes certain corporate costs not associated with the operations of the segment. These corporate costs are separately stated below and include costs that are related to functional areas such as operations management, corporate purchasing, accounting, treasury, information technology, legal and human resources. We believe that segment contribution margin, as defined above, is an appropriate measure for evaluating the operating performance of our segments. However, this measure should be considered in addition to, not a substitute for, or superior to, income from operations or other measures of financial performance prepared in accordance with generally accepted accounting principles. The other accounting policies of each of the two reporting segments are the same as those in Note A - Summary of Significant Accounting Policies of our Financial Statements.
In the Oil & Gas Proppants segment, we serve the oil and gas recovery market by providing fracturing sand, or “frac sand,” which is pumped down oil and natural gas wells to prop open rock fissures and increase the flow rate of oil and natural gas from the wells.
The Industrial & Specialty Products segment consists of over 250 products and materials used in a variety of industries including, container glass, fiberglass, specialty glass, flat glass, building products, fillers and extenders, foundry products, chemicals, recreation products and filtration products.
The following table presents sales and segment contribution margin for the reporting segments and other operating results not allocated to the reported segments for the three months ended March 31, 2015 and 2014:

ITEM 2.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read together with the Condensed Consolidated Financial Statements and the accompanying notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q as well as the Consolidated Financial Statements, the accompanying notes and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 (the "2014 Annual Report").
Overview
We are one of the largest domestic producers of commercial silica, a specialized mineral that is a critical input into a variety of attractive end markets. During our 115 year history, we have developed core competencies in mining, processing, logistics and materials science that enable us to produce and cost-effectively deliver over 260 products to customers across these markets. As of March 31, 2015, we operate 17 production facilities across the United States and control 360 million tons of reserves of commercial silica. We own one of the largest frac sand processing plants in the United States and control approximately 177 million tons of reserves that can be processed to meet American Petroleum Institute (API) frac sand size specifications. Our operations are organized into two segments based on end markets served: (1) Oil & Gas Proppants and (2) Industrial & Specialty Products. Our segments are complementary because our ability to sell to a wide range of customers across end markets allows us to maximize recovery rates in our mining operations, optimize our asset utilization and reduce the cyclicality of our earnings.
Recent Trends and Outlook
Oil and gas proppants end market trends
Increased demand for frac sand over the last several years has been driven by the growth in the use of hydraulic fracturing as a means to extract hydrocarbons from shale formations. According to the 2014 Proppant Market Report, PropTester Inc., published February 2015, global frac sand consumption grew at a 51.2% compound annual growth rate from 2009 to 2014. This included 53.7% growth in frac sand demand from 2013 to 2014. We significantly expanded our sales efforts to the frac sand market in 2008 and have since experienced rapid growth in our sales associated with our oil and gas activities.
Recent declines in oil prices have reduced oil and gas drilling activity in North America. According to internal U.S. Silica management estimates, we expect to see continued decline in 2015 proppant demand compared to 2014 due to decreased rig count, partially offset by higher proppant per well. During the three months ended March 31, 2015 we have experienced the impacts of declined demand from our customers. The table below summarizes some revenue metrics of our Oil & Gas Proppants segment for the three months ended March 31, 2015 compared to December 31, 2014:

A continued reduction in oil and gas drilling activities may reduce frac sand demand further, which could result in us selling fewer tons, selling tons at lower prices, or both. If we sell less frac sand, or sell frac sand at lower prices, our revenue, net income, cash generated from operating activities, and liquidity would be adversely affected. We could evaluate actions to reduce cost and improve liquidity. For instance, we may further reduce our capital spending for 2015 and beyond and may delay or cancel capital projects.
We believe the industry may experience temporary fluctuations in demand and price as the market adjusts to changing supply and demand due to energy pricing fluctuations. However, we continue to expect long-term growth in oil and gas drilling in North American shale basins.
Oil and natural gas exploration and production companies' and oilfield service providers’ preferences and expectations have been evolving in recent years. A proppant vendor’s logistics capabilities have become an important differentiating factor when competing for business on both a spot and contract basis. Many of our customers

18



increasingly seek convenient in-basin proppant delivery capability from their proppant supplier. We believe that, over time, proppant customers will prefer to consolidate their purchases across a smaller group of suppliers with robust logistics capabilities and a broad offering of high performance proppants.
Industrial and specialty products end market trends
Demand in the Industrial & Specialty Products end markets is relatively stable and is primarily influenced by key macroeconomic drivers such as housing starts, light vehicle sales, repair and remodel activity and industrial production. The economic downturn beginning in 2008 decreased demand in the foundry, building products and glassmaking end markets; however, the recent economic recovery has significantly increased demand in these end markets. The primary end markets served by our production used in Industrial & Specialty Products are foundry, building products, sports and recreation, glassmaking and filtration.
Our Strategy
The key drivers of our growth strategy include:
Expand our Oil & Gas Proppants production capacity and product portfolio. We continue to execute on several initiatives to increase our frac sand production capacity and augment our proppant product portfolio.
In 2014, we made an initial investment in a new Greenfield site near Fairchild, Wisconsin, which, depending on market conditions, could become operational as early as the first half of 2016 and eventually add 3,000,000 tons of annual demonstrated frac sand capacity.
In 2014, we made an initial investment in an 800,000 ton-per-year expansion at our Pacific, Missouri facility. This project includes adding a dryer as well as a new transload facility to support the additional volume and depending on market conditions, could come online as early as the first half of 2016.
On July 31, 2014, we completed our acquisition of Cadre, a leading regional sand mining company based in Voca, Texas. Cadre operates a single frac sand mine and plant, with an annual demonstrated capacity of about 800,000 tons of Premium Hickory® sand and has more than 65 years of high quality reserves. See accompanying Note D - Business Combinations of our Financial Statements for more information regarding this acquisition.
Increase our presence in industrial and specialty products end markets. We intend to increase our presence and market share in certain industrial and specialty products end markets that we believe are poised for growth. We will continue to work toward transforming our industrial and specialty product segment from a commodity business to a more value-driven approach by developing capabilities and products that assist in enabling us to increase our presence in larger, more profitable markets.
Optimize product mix and further develop value-added capabilities to maximize margins. We continue to actively manage our product mix at each of our plants to ensure we maximize our profit margins. This requires us to use our proprietary expertise in balancing key variables, such as mine geology, processing capacities, transportation availability, customer requirements and pricing. We expect to continue investing in ways to increase the value we provide to our customers by expanding our product offerings, increasing our transportation assets, improving our supply chain management, upgrading our information technology, and creating a world class customer service model.
Expand our supply chain network and leverage our logistics capabilities to meet our customers’ needs in each strategic oil and gas basin. We continue to expand our transload network to ensure product is available to meet the in-basin needs of our customers. This approach allows us to provide strong customer service and puts us in a position to take advantage of opportunistic spot market sales. Our plant sites are strategically located to provide access to key Class I railroads, which enables us to cost effectively send product to each of the strategic basins in North America. We can ship product by truck, barge and rail with an ability to connect to short-line railroads as necessary to meet our customers’ evolving in-basin product needs. We believe that our supply chain network and logistics capabilities are a competitive advantage that enables us to provide superior service for our customers. For example, in 2013, we opened our San Antonio, Texas unit-train receiving transload facility, which was built in partnership with BNSF Railway to support the Eagle Ford market. Additionally, in 2015, we opened our Odessa, Texas, two-unit-train storage capacity transload facility which was built in partnership with Union Pacific Railroad to support the Permian market. We will continue to make strategic investments and develop partnerships with transload operators and transportation providers that will enhance our portfolio of supply chain services that we can provide to customers. As of March 31, 2015, we have in-basin storage capacity at 35 transloads located near all of the major shale basins in the United States.

Evaluate both Greenfield and Brownfield expansion opportunities and other acquisitions. We will continue to leverage our reputation, processing capabilities and infrastructure to increase production, as well as explore other opportunities to expand our reserve base. We may accomplish this by developing Greenfield projects, where we can capitalize on our technical knowledge of geology, mining and processing and our strong reputation within local communities. For instance, we are evaluating the potential development of a Greenfield project in Wisconsin, which could add 3,000,000 tons of annual demonstrated frac sand capacity. Depending on market conditions, this facility could become operational as early as the end of 2016. Additionally, we are continuing to actively pursue acquisitions to grow, by taking advantage of our asset footprint, our management’s experience with high-growth businesses, and our strong customer relationships. Our primary objective is to acquire assets with differing levels of frac sand quality that are complementary to our Oil & Gas Proppants segment, with a focus on mining, processing and logistics to further enhance our market presence. We prioritize acquisitions that provide opportunities to realize synergies (and, in some cases, the acquisition may be accretive assuming synergies), including entering new geographic and frac sand product markets, acquiring attractive customer contracts and improving operations. For instance, we completed the Cadre acquisition on July 31, 2014, which generated synergies and positively impacted our results of operations. See accompanying Note D - Business Combinations of our Financial Statements for pro forma results of operations related to the Cadre acquisition. We are in active discussions to acquire assets fitting this strategy, which, if completed, would be “significant” under Regulation S-X and could require additional sources of financing. There can be no assurance that we will reach a definitive agreement and complete any of these potential transactions. See the risk factors disclosed in Item 1A of Part I of our 2014 Annual Report, including the risk factor entitled, “If we cannot successfully complete acquisitions or integrate acquired businesses, our growth may be limited and our financial condition may be adversely affected.”
Maintain financial strength and flexibility. We intend to maintain financial strength and flexibility to enable us to pursue acquisitions and new growth opportunities as they arise. In July 2013, we refinanced our existing senior secured debt by replacing our revolving line-of-credit and amending our senior secured term loan facility (the “Term Loan”), increasing the Term Loan amount by approximately $115.0 million. In December 2014, we upsized our Term Loan by an additional $135.0 million to a total of approximately $500.0 million. As of March 31, 2015, we had $252.6 million of cash on hand, $75.3 million in short-term investments and $46.9 million of availability under our revolver.
How We Generate Our Sales
We derive our sales by mining and processing minerals that our customers purchase for various uses. Our sales are primarily a function of the price per ton and the number of tons sold. The price invoiced reflects product, transportation and additional services as applicable, such as storage and transloading the product from railcars to trucks for delivery to the customer site. We invoice the majority of our customers on a per shipment basis, although for some larger customers, we consolidate invoices weekly or monthly. Our five largest customers accounted for approximately 47% of total sales during the three months ended March 31, 2015. Sales to our two largest customers, Schlumberger N.V. and Halliburton Company accounted for 16% and 14% of our total revenues, respectively, during the three months ended March 31, 2015. No other customer accounted for 10% or more of our total revenues.
We primarily sell our products under short-term price agreements or at prevailing market rates. For a number of customers, we sell under long-term, competitively-bid contracts. As of April 29, 2015, we have 9 take-or-pay supply agreements in the Oil & Gas Proppants segment with initial terms expiring between 2015 and 2019. These agreements define, among other commitments, the volume of product that our customers must purchase, the volume of product that we must provide and the price that we will charge and that our customers will pay for each product. Prices under these agreements are generally fixed and subject to upward adjustment in response to certain cost increases. Additionally, at the time the take-or-pay supply agreements were signed, some customers provided advance payments for future shipments. A percentage of these advance payments was recognized as revenue with each ton of applicable product shipped to the customer. Collectively, sales to customers with take-or-pay supply agreements accounted for 36% and 33% of our total company revenue during the three months ended March 31, 2015 and 2014, respectively. Although sales under take-or-pay supply agreements, as opposed to short-term price agreements or at prevailing spot market rates, result in us realizing lower margins than we otherwise might during periods of high market prices, we believe such lower margins are offset by the benefits derived from the product mix and sales volume stability afforded by such supply agreements, which helps us lower market risk arising from adverse changes in spot prices and market conditions. Additionally, selling more tons under supply contracts also enables us to be more efficient from a production, supply chain and logistics standpoint. As discussed in Part I, Item 1A, of our 2014 Annual Report, “Risk Factors—A large portion of our sales is generated by our top customers, and the loss of, or significant reduction in, purchases by our largest customers could adversely affect our operations,” these customers may not continue to purchase the same levels of product in the future due to a variety of reasons, contract requirements notwithstanding.

The Costs of Conducting Our Business
The principal expenses involved in conducting our business are labor costs, electricity and drying fuel costs, maintenance and repair costs for our mining and processing equipment and facilities and transportation costs. Transportation and related costs include freight charges, fuel surcharges, transloading fees, switching fees, railcar lease costs, demurrage costs and storage fees. We believe the majority of our operating costs are relatively stable in price, but can vary significantly based on the volume of product produced. We benefit from owning the majority of the mineral deposits that we mine and having long-term mineral rights leases or supply agreements for our other primary sources of raw material, which limit royalty payments.
Additionally, we incur expenses related to our corporate operations, including costs for sales and marketing; research and development; and finance, legal, environmental, health and safety functions of our organization. These costs are principally driven by personnel expenses.
How We Evaluate Our Business
Our management team evaluates our business using a variety of financial and operational metrics. Our business is organized into two segments, Oil & Gas Proppants and Industrial & Specialty Products. We evaluate the performance of these segments based on their tons sold, average selling price and contribution margin earned. Additionally, we consider a number of factors in evaluating the performance of the business as a whole, including total tons sold, average selling price, segment contribution margin, and Adjusted EBITDA. We view these metrics as important factors in evaluating our profitability and review these measurements frequently to analyze trends and make decisions.
Segment Contribution Margin
Segment contribution margin, a non-GAAP measure, is a key metric that management uses to evaluate our operating performance and to determine resource allocation between segments. Segment contribution margin excludes certain corporate costs not associated with the operations of the segment. These unallocated costs include costs that are related to corporate functional areas such as operations management, corporate purchasing, accounting, treasury, information technology, legal and human resources.
Segment contribution margin is not a measure of our financial performance under GAAP and should not be considered an alternative to measures derived in accordance with GAAP. For more details on the reconciliation of segment contribution margin to its most directly comparable GAAP financial measure, income (loss) before income taxes, see Note P - Segment Reporting to our Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Adjusted EBITDA
Adjusted EBITDA, a non-GAAP measure, is included in this report because it is a key metric used by management to assess our operating performance and by our lenders to evaluate our covenant compliance. Our target performance goals under our incentive compensation plan are tied, in part, to our Adjusted EBITDA. In addition, our Revolver contains a consolidated total net leverage ratio that we must meet as of the last day of any fiscal quarter whenever usage of the Revolver (other than certain undrawn letters of credit) exceeds 25% of the Revolver commitment, which is calculated based on our Adjusted EBITDA. Noncompliance with the financial ratio covenant contained in the Revolver could result in the acceleration of our obligations to repay all amounts outstanding under the Revolver and the Term Loan. Moreover, the Revolver and the Term Loan contain covenants that restricted, subject to certain exceptions, our ability to make permitted acquisitions, incur additional indebtedness, make restricted payments (including dividends) and retain excess cash flow based, in some cases, on our ability to meet leverage ratios calculated based on our Adjusted EBITDA.
Adjusted EBITDA is not a measure of our financial performance or liquidity under GAAP and should not be considered as an alternative to net income as a measure of operating performance, cash flows from operating activities as a measure of liquidity or any other performance measure derived in accordance with GAAP. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized, and excludes certain non-recurring charges. Management compensates for these limitations by relying primarily on our GAAP results and by using Adjusted EBITDA only supplementally. Our measure of Adjusted EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the methods of calculation.

Total sales increased 13% for the three months ended March 31, 2015 compared to the three months ended March 31, 2014, driven by a 16% increase in total tons sold partially offset by a 2% decrease in overall average selling price. Tons sold in-basin represented 40% of total company tons sold for both the three months ended March 31, 2015 and 2014.
The majority of the increase in total sales was driven by Oil & Gas Proppants sales, which increased 14%. Oil & Gas Proppants tons sold for the three months ended March 31, 2015 increased 26% mainly driven by the addition of Cadre sales and year over year growth in the demand for our frac sand. The incremental revenue from this increase in tons sold was partially offset by a 10% decrease in average selling price resulting from decreased tons sold through transloads as a percentage of total tons sold.

22



Industrial & Specialty Products sales increased 12% for the three months ended March 31, 2015 compared to the three months ended March 31, 2014, driven by a 1% increase in tons sold and an 11% increase in average selling price. The increase in average selling price was primarily a result of new higher-margin product sales and price increases implemented during 2014.
Cost of Goods Sold
Cost of goods sold increased by $11.9 million, or 9%, to $138.7 million for the three months ended March 31, 2015 compared to $126.8 million for the three months ended March 31, 2014. The increase is mainly a result of more tons sold. As a percentage of sales, costs of goods sold decreased to 68% for the three months ended March 31, 2015 compared to 70% for the same period in 2014. These changes result from the main components of cost of goods sold as discussed below.
We incurred $73.0 million and $74.0 million of transportation and related costs for the three months ended March 31, 2015 compared to the same period in 2014, respectively. This decrease was due to fewer tons sold through transloads caused by lower demand for our frac sand at our transload sites. As a percentage of sales, transportation and related costs decreased to 36% for the three months ended March 31, 2015 compared to 41% for the same period in 2014 due to decreased tons sold through transloads as a percentage of total tons sold.
We incurred $21.3 million and $16.1 million of operating labor costs for the three months ended March 31, 2015 and 2014, respectively. The increases in labor costs incurred were due to producing and selling more tons. As a percentage of sales, operating labor costs represented 10% for the three months ended March 31, 2015 compared to 9% for the same period in 2014.
We incurred $8.2 million and $8.5 million of electricity and drying fuel (principally natural gas) costs for the three months ended March 31, 2015 and 2014, respectively. The decrease in electricity and drying fuel costs incurred was due to lower natural gas rates, partially offset by higher tons sold. As a percentage of sales, electricity and drying fuel costs slightly decreased to 4% for the three months ended March 31, 2015 compared to 5% for the same period in 2014.
We incurred $10.2 million and $6.2 million of maintenance and repair costs for the three months ended March 31, 2015 and 2014, respectively. The increase in maintenance and repair costs incurred were due to scheduled maintenance and the addition of production facilities, including our Voca, Texas and Utica, Illinois facilities. As a percentage of sales, maintenance and repair costs increased to 5% for the three months ended March 31, 2015 compared to 3% for the same period in 2014.
Segment Contribution Margin
Oil & Gas Proppants contribution margin increased by $10.6 million, or 25%, to $52.2 million for the three months ended March 31, 2015 compared to $41.6 million for the three months ended March 31, 2014, mainly driven by a 26% increase in tons sold discussed above.
Industrial & Specialty Products contribution margin increased by $2.3 million, or 17%, to $15.5 million for the three months ended March 31, 2015 compared to $13.2 million for the three months ended March 31, 2014, driven by increases in tons sold and average selling price discussed above, partially offset by an increase in cost of goods sold.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased by $11.5 million, or 75%, to $27.0 million for the three months ended March 31, 2015 compared to $15.4 million for the three months ended March 31, 2014. The increase is due to the following factors:
Business development-related expense increased by $6.4 million to $8.3 million for the three months ended March 31, 2015 compared to $1.9 million for the three months ended March 31, 2014. This increase is due to a $7.6 million accrual as a result of an unfavorable arbitration ruling. See Note L - Commitments and Contingencies of our Financial Statements for more information about this arbitration ruling.
Compensation-related expense increased by $3.8 million to $13.2 million for the three months ended March 31, 2015 compared to $9.4 million for the three months ended March 31, 2014.
We also incurred restructuring cost of $1.4 million during the three months ended March 31, 2015 for actions that will provide future cost savings.
In total, our selling, general and administrative costs represented approximately 13% and 9% of our sales for the three months ended March 31, 2015 and 2014, respectively.

23



Depreciation, Depletion and Amortization
Depreciation, depletion and amortization expense increased by $3.7 million, or 38%, to $13.2 million for the three months ended March 31, 2015 compared to $9.6 million for the three months ended March 31, 2014. Year over year increases were driven by continued capital spending associated with our growth and capacity expansion initiatives. We expect depreciation, depletion and amortization expense to continue to grow due to anticipated capital spending in 2015. Depreciation, depletion and amortization costs represented approximately 6% and 5% of our sales for the three months ended March 31, 2015 and 2014, respectively.
Operating Income
Operating income decreased by $3.2 million, or 11%, to $25.1 million for the three months ended March 31, 2015 compared to $28.3 million for the three months ended March 31, 2014. The decrease was due to a 9% increase in cost of goods sold and a 61% increase in operating expenses, partially offset by a 13% increase in sales.
Interest Expense
Interest expense increased by $3.0 million, or 80%, to $6.8 million for the three months ended March 31, 2015 compared to $3.8 million for the three months ended March 31, 2014, mainly due to an increase in debt principal and additional interest expense related to the deferred revenue.
Provision for Income Taxes
The provision for income taxes decreased by $2.7 million, or 44%, to $3.5 million for the three months ended March 31, 2015 compared to $6.2 million for the three months ended March 31, 2014. The decreases were driven by a lower effective tax rate and decreased pretax book income. The effective tax rate was 19% and 25% for the three months ended March 31, 2015 and 2014, respectively. See accompanying Note M - Income Taxes of our Financial Statements for more information.
Historically, our actual effective tax rates have been lower than the statutory effective rate primarily due to the benefit received from statutory percentage depletion allowances. The deduction for statutory percentage depletion does not necessarily change proportionately to changes in income before income taxes.
Net Income/Loss
Net income was $14.8 million and $18.4 million for the three months ended March 31, 2015 and 2014, respectively. The year over year decrease was due to the factors noted above.

24



Liquidity and Capital Resources
Overview
Our principal liquidity requirements have historically been to service our debt, to meet our working capital, capital expenditure and mine development expenditure needs, to return cash to our stockholders, and to finance acquisitions. We have historically met our liquidity and capital investment needs with funds generated through operations. We have historically funded our acquisitions through cash on hand or borrowings under our credit facilities and equity investments. Our working capital is the amount by which current assets exceed current liabilities and is a measure of our ability to pay our liabilities as they become due. As of March 31, 2015, our working capital was $404.5 million and we had $46.9 million of availability under the Revolver.
We believe that cash generated through operations and our financing arrangements will be sufficient to meet working capital requirements, anticipated capital expenditures, scheduled debt payments for at least the next 12 months and any dividends declared.
Management and our Board remain committed to evaluating additional ways of creating shareholder value. Any determination to pay dividends and other distributions in cash, stock, or property in the future will be at the discretion of our Board and will be dependent on then-existing conditions, including our business conditions, our financial condition, results of operations, liquidity, capital requirements, contractual restrictions including restrictive covenants contained in debt agreements, and other factors. Additionally, because we are a holding company, our ability to pay dividends on our common stock may be limited by restrictions on the ability of our subsidiaries to pay dividends or make distributions to us, including restrictions under the terms of the agreements governing our indebtedness.

Net Cash Provided by Operating Activities
Operating activities consist primarily of net income adjusted for certain non-cash and working capital items. Adjustments to net income for non-cash items include depreciation, depletion and amortization, deferred revenue, deferred income taxes, equity-based compensation and allowance for doubtful accounts. In addition, operating cash flows include the effect of changes in operating assets and liabilities, principally accounts receivable, inventories, prepaid expenses and other current assets, income taxes payable and receivable, accounts payable and accrued expenses.
Net cash provided by operating activities was $19.8 million for the three months ended March 31, 2015 compared to $30.3 million for the three months ended March 31, 2014. This $10.5 million decrease in cash provided by operations was mainly the result of a $3.5 million decrease in net income and a $6.9 million decrease resulting from working capital activities.
Net Cash Used in Investing Activities
Investing activities consist primarily of capital expenditures for growth and maintenance.
Net cash used in investing activities was $13.3 million and $10.6 million for the three months ended March 31, 2015 and 2014, respectively. Capital expenditures for the three months ended March 31, 2015, which totaled $13.4 million, were primarily for the engineering, procurement and construction of our Greenfield raw sand plant near Fairchild, Wisconsin, our new transload facility in Odessa, Texas, an expansion project at our Pacific, Missouri facility and other maintenance capital projects. Capital expenditures for the three months ended March 31, 2014, which totaled $10.6 million, were primarily for the continuing engineering, procurement and construction of our Greenfield raw sand plant in Utica, Illinois, our new transload facility in Odessa, Texas, and other maintenance capital projects.

25



Subject to our continuing evaluation of market conditions, we anticipate that our capital expenditures in 2015 will be in a range of $60 million to $80 million , which is primarily associated with growth and maintenance capital including the construction of the mine and processing facility in Fairchild, Wisconsin. We expect to fund our capital expenditures through cash on our balance sheet, cash generated from our operations and cash generated from financing activities.
Net Cash Used in Financing Activities
Financing activities consist primarily of equity issuances, capital contributions, dividend payments, borrowings and repayments related to the Revolver and Term Loan, as well as fees and expenses paid in connection with our credit facilities, advance payments from our customers, and outstanding checks to our vendors.
Net cash used in financing activities was $21.2 million for the three months ended March 31, 2015, driven by $15.3 million of common stock repurchases, $6.8 million of dividends paid and $1.3 million of long-term debt payments partially offset by a $4.7 million change in our book overdraft.
Net cash used in financing activities was $12.3 million in the three months ended March 31, 2014, driven by $13.4 million in dividend payments and a $2.0 million decrease in book overdraft, partially offset by $3.0 million of proceeds from employee exercises of stock options.
Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements that have or are likely to have a current or future material effect on our financial condition, changes in financial condition, sales, expenses, results of operations, liquidity, capital expenditures or capital resources.
Contractual Obligations
There have been no significant changes outside the ordinary course of business to our “Contractual Obligations” table in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of our 2014 Annual Report, except that we entered into additional new leases for railroad cars. For more details on future minimum annual commitments under such operating leases, please see accompanying Note L - Commitments and Contingencies to our Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Environmental Matters
We are subject to various federal, state and local laws and regulations governing, among other things, hazardous materials, air and water emissions, environmental contamination and reclamation and the protection of the environment and natural resources. We have made, and expect to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures. As of March 31, 2015, we had $11.5 million accrued for future reclamation costs, as compared to $11.3 million as of December 31, 2014.
We discuss certain environmental matters relating to our various production and other facilities, certain regulatory requirements relating to human exposure to crystalline silica and our mining activity and how such matters may affect our business in the future under Item 1, “Business,” Item 1A, “Risk Factors” Item 3, “Legal Proceedings”, and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Environmental Matters” in our 2014 Annual Report.

Critical Accounting Estimates
Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of our financial statements and the reported amounts of revenues and expenses during the reporting period. While we do not believe that the reported amounts would be materially different, application of these policies involves the exercise of judgment and the use of assumptions as to future uncertainties and, as a result, actual results could differ from these estimates. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on experience and on various other assumptions that are believed to be reasonable under the circumstances. All of our significant accounting policies, including certain critical accounting policies, are disclosed in our 2014 Annual Report.
Recent Accounting Pronouncements
New accounting guidance that we have recently adopted, as well as accounting guidance that has been recently issued but not yet adopted by us, are included in Note A - Summary of Significant Accounting Policies to our Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risk
We are exposed to certain market risks, which exist as a part of our ongoing business operations. Such risks arise from adverse changes in market rates, prices and conditions. We address such market risks as discussed in "How We Generate Our Sales" in Item 2 of this Form 10-Q, Management's Discussion and Analysis of Financial Condition and Results of Operations.
Interest Rate Risk
We are exposed to interest rate risk arising from adverse changes in interest rates. As of March 31, 2015, we have $503.1 million of debt outstanding under our senior credit facility. Assuming no change in the amount outstanding, and LIBOR is greater than the 1.0% minimum base rate on the Term Loan, a hypothetical increase or decrease in interest rates by 1.0% would have changed our interest expense by $1.4 million per year.
We use interest rate derivatives in the normal course of our business to manage both our interest cost and the risks associated with changing interest rates. We do not use derivatives for trading or speculative purposes. The following table summarizes the fair value of our derivative instruments at March 31, 2015 and December 31, 2014.

Agreements limit the LIBOR floating interest rate base to 4%.
Credit Risk
We are subject to risks of loss resulting from nonpayment or nonperformance by our customers. We examine the creditworthiness of third-party customers to whom we extend credit and manage our exposure to credit risk through credit analysis, credit approval, credit limits and monitoring procedures, and for certain transactions, we may request letters of credit, prepayments or guarantees, although collateral is generally not required. Despite enhancing our examination of our customers' credit worthiness, we may still experience delays or failures in customer payments.

ITEM 4.
CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2015. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of March 31, 2015, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended March 31, 2015 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION
 
ITEM 1.
LEGAL PROCEEDINGS
In addition to the matter described below, we are subject to various legal proceedings, claims, and governmental inspections, audits or investigations arising out of our business which cover matters such as general commercial, governmental regulations, antitrust and trade regulations, product liability, environmental, intellectual property, employment and other actions. Although the outcomes of these routine claims cannot be predicted with certainty, in the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on our financial position or results of operations.
Prolonged inhalation of excessive levels of respirable crystalline silica dust can result in silicosis, a disease of the lungs. Breathing large amounts of respirable silica dust over time may injure a person’s lungs by causing scar tissue to form. Crystalline silica in the form of quartz is a basic component of soil, sand, granite and most other types of rock. Cutting, breaking, crushing, drilling, grinding and abrasive blasting of or with crystalline silica containing materials can produce fine silica dust, the inhalation of which may cause silicosis, lung cancer and possibly other diseases including immune system disorders such as scleroderma. Sources of exposure to respirable crystalline silica dust include sandblasting, foundry manufacturing, crushing and drilling of rock, masonry and concrete work, mining and tunneling, and cement and asphalt pavement manufacturing.
Since at least 1975, we and/or our predecessors have been named as a defendant, usually among many defendants, in numerous lawsuits brought by or on behalf of current or former employees of our customers alleging damages caused by silica exposure. Prior to 2001, the number of silicosis lawsuits filed annually against the commercial silica industry remained relatively stable and was generally below 100, but between 2001 and 2004 the number of silicosis lawsuits filed against the commercial silica industry substantially increased. This increase led to greater scrutiny of the nature of the claims filed, and in June 2005 the U.S. District Court for the Southern District of Texas issued an opinion in the former federal silica multi-district litigation remanding almost all of the 10,000 cases then pending in the multi-district litigation back to the state courts from which they originated for further review and medical qualification, leading to a number of silicosis case dismissals across the United States. In conjunction with this and other favorable court rulings establishing “sophisticated user” and “no duty to warn” defenses for silica producers, several states, including Texas, Ohio and Florida, have passed medical criteria legislation that requires proof of actual impairment before a lawsuit can be filed.
As a result of the above developments, the filing rate of new claims against us over the past three years has decreased to below pre-2001 levels, and we were named as a defendant in three, two and three new silicosis cases filed in 2011, 2012 and 2013, respectively. During the three months ended March 31, 2015, no additional claims were brought against us. As of April 29, 2015, there are a total of approximately 0 active silica-related products liability claims pending in which we were a defendant and approximately 0 inactive claims. Almost all of the claims pending against us arise out of the alleged use of our silica products in foundries or as an abrasive blast media, and involve various other defendants. Prior to the fourth quarter of 2012, we had insurance policies for both our predecessors that covered certain claims for alleged silica exposure for periods prior to certain dates in 1985 and 1986 (with respect to certain insurance). As a result of a settlement with a former owner of ours and its insurers in the fourth quarter of 2012, some of these policies are no longer available to us, and we will not seek reimbursement for any defense costs or claim payments from these policies. Other insurance policies, however, continue to remain available to us and will continue to make such payments on our behalf.
The silica-related litigation brought against us to date has not resulted in material liability to us. However, we continue to have silica-related products liability claims filed against us, including claims that allege silica exposure for periods for which we do not have insurance coverage. Any such pending or future claims or inadequacies of our insurance coverage could have a material adverse effect on our business, reputation or results of operations. For more information regarding silica-related litigation, see Part I, Item 1A of our 2014 Annual Report “Risk Factors—Risks Related to Our Business—Silica-related health issues and litigation could have a material adverse effect on our business, reputation or results of operations.”

ITEM 4.
MINE SAFETY DISCLOSURES
Safety is one of our core values, and we strive for excellence in the achievement of a workplace free of injuries and occupational illnesses. Our health and safety leadership team has developed comprehensive safety policies and standards, which include detailed standards and procedures for safe production, addressing topics such as employee training, risk management, workplace inspection, emergency response, accident investigation and program auditing. We place special emphasis on the importance of continuous improvement in occupational health, personal injury avoidance and prevention, emergency preparedness, and property damage elimination. In addition to strong leadership and involvement from all levels of the organization, these programs and procedures form the cornerstone of our safety initiatives, ensuring that employees are provided a safe and healthy environment and are intended as a means to reduce workplace accidents, incidents and losses, comply with all mining-related regulations and provide support for both regulators and the industry to improve mine safety. While we want to have productive operations in full regulatory compliance, we know it is equally essential that we motivate and train our people to think, practice and feel a personal responsibility for health and safety on and off the job.
All of our production facilities, with the exception of our resin-coated sand facility, are classified as mines and are subject to regulation by the Federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). MSHA inspects our mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Following passage of The Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the numbers of citations and orders charged against mining operations. The dollar penalties assessed for citations issued has also increased in recent years. Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95.1 to this Quarterly Report filed on Form 10-Q.

ITEM 5.
OTHER INFORMATION
Forward Looking Statements
This Quarterly Report on Form 10-Q contains forward-looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact included in this Quarterly Report on Form 10-Q are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “plan,” “intend,” “believe,” “may,” “will,” “should,” “can have,” “likely” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. For example, all statements we make relating to our estimated and projected costs, expenditures, cash flows, growth rates and financial results, our plans and objectives for future operations, growth or initiatives, strategies or the expected outcome or impact of pending or threatened litigation are forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expected, including:
fluctuations in demand for commercial silica;
the cyclical nature of our customers’ businesses;
operating risks that are beyond our control, such as changes in the price and availability of transportation, natural gas or electricity; unusual or unexpected geological formations or pressures; cave-ins, pit wall failures or rock falls; or unanticipated ground, grade or water conditions;
our dependence on three of our plants for a significant portion of our sales;
the level of activity in the natural gas and oil industries;
decreased demand for frac sand or the development of either effective alternative proppants or new processes to replace hydraulic fracturing;
federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing and the potential for related regulatory action or litigation affecting our customers’ operations;
our rights and ability to mine our properties and our renewal or receipt of the required permits and approvals from governmental authorities and other third parties;

our ability to succeed in competitive markets;
loss of, or reduction in, business from our largest customers;
increasing costs or a lack of dependability or availability of transportation services and transload network access infrastructure;
increases in the prices of, or interruptions in the supply of, natural gas and electricity, or any other energy sources;
increases in the price of diesel fuel;
diminished access to water;
our ability to successfully complete acquisitions or integrate acquired businesses;
our ability to make capital expenditures to maintain, develop and increase our asset base and our ability to obtain needed capital or financing on satisfactory terms;
our substantial indebtedness and pension obligations;
restrictions imposed by our indebtedness on our current and future operations;
contractual obligations that require us to deliver minimum amounts of frac sand or purchase minimum amounts of services
the accuracy of our estimates of mineral reserves and resource deposits;
a shortage of skilled labor and rising costs in the mining industry;

32



our ability to attract and retain key personnel;
our ability to maintain satisfactory labor relations;
our reliance on trade secrets and contractual restrictions, rather than patents, to protect our proprietary rights;
our significant unfunded pension obligations and post-retirement health care liabilities;
our ability to maintain effective quality control systems at our mining, processing and production facilities;
seasonal and severe weather conditions;
fluctuations in our sales and results of operations due to seasonality and other factors;
interruptions or failures in our information technology systems;
the impact of a terrorist attack or armed conflict;
extensive and evolving environmental, mining, health and safety, licensing, reclamation and other regulation (and changes in their enforcement or interpretation);
silica-related health issues and corresponding litigation;
our ability to acquire, maintain or renew financial assurances related to the reclamation and restoration of mining property; and
other factors included and disclosed in Part I, Item 1A, “Risk Factors” of our 2014 Annual Report.
We derive many of our forward-looking statements from our operating budgets and forecasts, which are based on many detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. Important factors that could cause actual results to differ materially from our expectations, or cautionary statements, are disclosed under Item 1A, “Risk Factors” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2014 Annual Report. All written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by these cautionary statements as well as other cautionary statements that are made from time to time in our other filings with the SEC, including this Quarterly Report on Form 10-Q, and public communications. You should evaluate all forward-looking statements made in this Quarterly Report on Form 10-Q in the context of these risks and uncertainties.
We caution you that the important factors referenced above may not contain all of the factors that are important to you. In addition, we cannot assure you that we will realize the results or developments we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our operations in the way we expect. The forward-looking statements included in this Quarterly Report on Form 10-Q are made only as of the date hereof. We undertake no obligation to update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
