	1	Significant Accounting Policies
	Basis of Presentation
	The unaudited condensed consolidated financial statements of FMSA Holdings Inc. and its consolidated subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments (which are of a normal, recurring nature) and disclosures necessary for a fair presentation of the financial position, results of operations, comprehensive income and cash flows of the reported interim periods. The condensed consolidated balance sheet as of December 31, 2013 was derived from audited financial statements, but does not include all disclosures required by GAAP. Interim results are not necessarily indicative of the results to be expected for the full year or any other interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements as filed in the S-1 and S-1A and notes thereto included elsewhere in this quarterly report on Form 10-Q.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Recent Accounting Pronouncements
	In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity(ASU 2014-08), which amended existing requirements for reporting discontinued operations. Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. The guidance is effective for disposal transactions occurring in reporting periods beginning after December 15, 2014. Presentation and disclosures of future disposal transactions after adoption of the guidance may be different than under current standards.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). Under ASU 2014-09, companies recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled, in exchange for those goods or services. The new requirements significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The Company is not required to adopt this reporting standard until reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. The Company is in the process of evaluating the effect of the new guidance on our financial statements and disclosures.

	In February 2014 the Company executed a joinder agreement to borrow $41,000 as an additional Term Loan B-2. The proceeds of this borrowing were used to repay then outstanding amounts under the revolving credit facility. The additional borrowings mature on the same date as the then existing Term Loan B-2 (September 5, 2019) and the required quarterly principal repayments for the Term Loan B-2 were increased by one-quarter of 1% of the amount borrowed with the balance due at maturity. There were no other changes in the terms, interest rates or covenants of the 2013 Amended Credit Agreement.
	In March 2014 the Company amended the existing 2013 Amended Credit Agreement whereby the applicable margin for the Term Loan B-1 and the Term Loan B-2 base rate loans was reduced to 2.50% and the applicable margin for the Term Loan B-1 and the Term Loan B-2 Eurodollar rate loans was reduced to 3.50%.
	In August and September 2014, the Company executed additional joinder agreements for incremental revolving commitments to the Revolving Credit Facility for $46,629 and $3,371 respectively, which brings the Company’s total Revolving Credit Facility commitment to $125,000. As of September 30, 2014, there was $113,500 available borrowing remaining on this facility. There were no other changes in the terms, interest rates or covenants of the Revolving Credit Facility.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	6	Derivative Instruments
	The Company enters into interest rate swap agreements as a means to hedge its variable interest rate risk on debt instruments. The notional value of these swap agreements is $542,300 at September 30, 2014 and effectively fixes the variable rate in a range of 0.83% to 3.115%. The notional amount of these instruments is scheduled to increase over time to provide a hedge against variable interest rate debt. The interest rate swap agreements mature at various dates between March 31, 2015 and September 5, 2019.
	The derivative instruments are recorded on the balance sheet at their fair values. Changes in the fair value of derivatives are recorded each period in current earnings or in other comprehensive income, depending on whether a derivative is designated as part of a hedging relationship and, if it is, depending on the type of hedging relationship. For cash flow hedges in which the Company is hedging the variability of cash flows related to a variable-rate liability, the effective portion of the gain or loss on the derivative instrument is reported in other comprehensive income in the periods during which earnings are impacted by the variability of the cash flows of the hedged item. The ineffective portion of all hedges is recognized in current period earnings. As interest expense is accrued on the debt obligation, amounts in accumulated other comprehensive income (loss) related to the interest rate swaps are reclassified into income to obtain a net cost on the debt obligation equal to the effective yield of the fixed rate of each swap. In the event that an interest rate swap is terminated prior to maturity, gains or losses in accumulated other comprehensive income (loss) remain deferred and are reclassified into earnings in the periods in which the hedged forecasted transaction affects earnings.
	The Company formally designates and documents instruments at inception that qualify for hedge accounting of underlying exposures in accordance with GAAP. Both at inception and for each reporting period, the Company assesses whether the financial instruments used in hedging transactions are effective in offsetting changes in cash flows of the related underlying exposure.
	The following table summarizes the fair values and the respective classification in the Condensed Consolidated Balance Sheets as of September 30, 2014 and December 31, 2013:
				Assets (Liabilities)
				September 30,			December 31,
	Interest Rate Swap Agreements		Balance Sheet Classification	2014			2013
	Designated as hedges		Other long-term liabilities	$	(7,060	)	$	(2,297	)
	Not designated as hedges		Other long-term liabilities		(1,947	)		(3,340	)
	Designated as hedges		Other assets		639			2,706
				$	(8,368	)	$	(2,931	)
	The Company recognized $14 and $0 in interest expense, representing the ineffective portion of interest rate swap agreements designated as hedges, in the nine months ended September 30, 2014 and 2013, respectively. The Company expects $2,351 to be reclassified from accumulated other comprehensive income into interest expense in the twelve-month period ending September 30, 2015.

Fair Value Measurements	'
	7	Fair Value Measurements
	Financial instruments held by the Company include cash equivalents, accounts receivable, accounts payable, long-term debt and interest rate swaps. The Company is also liable for contingent consideration from an acquisition that is subject to fair value measurement. Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. In determining fair value, the Company utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique.
	Based on the examination of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
	Level 1		Quoted market prices in active markets for identical assets or liabilities
	Level 2		Observable market based inputs or unobservable inputs that are corroborated by market data
	Level 3		Unobservable inputs that are not corroborated by market data
	A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The book value of cash equivalents, accounts receivable and accounts payable are considered to be representative of their fair values because of their short maturities. The carrying value of the Company’s debt is also considered to be representative of its fair value since the interest rate is variable and fluctuates with the market.
	The following table presents the amounts carried at fair value as of September 30, 2014 and December 31, 2013 for the Company’s other financial instruments. The Contingent consideration liability was satisfied in July 2014.

	The Company computes and applies to ordinary income an estimated annual effective tax rate on a quarterly basis based on current and forecasted business levels and activities, including the mix of domestic and foreign results and enacted tax laws. The estimated annual effective tax rate is updated quarterly based on actual results and updated operating forecasts. Ordinary income refers to income (loss) before income tax expense excluding significant, unusual, or infrequently occurring items. The tax effect of an unusual or infrequently occurring item is recorded in the interim period in which it occurs as a discrete item of tax.
	For the three months ended September 30, 2014, the Company recorded tax expense of $21,436 on income before income taxes of $75,598. For the nine months ended September 30, 2014, the Company recorded tax expense of $53,848 on income before income taxes of $186,825. For the three months ended September 30, 2013 the Company recorded tax expense of $11,032 on income before income taxes of $36,048. For the nine months ended September 30, 2013 the Company recorded tax expense of $40,726 on income before income taxes of $134,558. The effective tax rate for the three and nine months ended September 30, 2014 was 28.4% and 28.8%, respectively, as compared with 30.6% and 30.3% for the three and nine months ended September 30, 2013, respectively. The decrease in the effective tax rates from the preceding fiscal periods was primarily due to adjustments for prior years’ tax liabilities that were recorded in the 2013 tax expense.

	Certain subsidiaries are defendants in lawsuits in which the alleged injuries are claimed to be silicosis-related and to have resulted, in whole or in part, from exposure to silica-containing products, allegedly including those sold by certain subsidiaries. In the majority of cases, there are numerous other defendants. In accordance with its insurance obligations, the defense of these actions has been tendered to and the cases are being defended by the subsidiaries’ insurance carriers. Management believes that the Company’s substantial level of existing and available insurance coverage combined with various open indemnities is more than sufficient to cover any exposure to silicosis-related expenses. An estimate of the possible loss, if any, cannot be made at this time.
	The Company has entered into numerous mineral rights agreements, in which payments under the agreements are expensed as incurred. Certain agreements require annual payments while other agreements require payments based upon annual tons mined and others a combination thereof.
	The Company leases certain machinery, equipment (including railcars), buildings and office space under operating lease arrangements. Total rent expense associated with these leases was $39,130 and $20,973 for the nine months ended September 30, 2014 and 2013, respectively.
	The Company is subject to a contingent consideration arrangement related to the purchase of Self-Suspending Proppant LLC (“SSP”), which was accounted for as an acquisition of a group of assets. The contingent consideration is based on a fixed percentage of the cumulative product margin, less certain adjustments, generated by sales of Propel SSP and other products incorporating SSP technology for the five years commencing on October 1, 2015. Because the earnout is dependent on future sales and the related cost of sales, the amounts of which are highly uncertain, it is not currently possible to estimate the amounts that will be paid. The contingent consideration will be accrued and capitalized as part of the cost of the SSP assets at the time a payment is probable and reasonably estimable.

	The Company organizes its business into two reportable segments, Proppant Solutions and Industrial & Recreational Products. The reportable segments are consistent with how management views the markets served by the Company and the financial information reviewed by the chief operating decision maker in deciding how to allocate resources and assess performance.
	The chief operating decision maker primarily evaluates an operating segment’s performance 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.

	Basis of Presentation
	The unaudited condensed consolidated financial statements of FMSA Holdings Inc. and its consolidated subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments (which are of a normal, recurring nature) and disclosures necessary for a fair presentation of the financial position, results of operations, comprehensive income and cash flows of the reported interim periods. The condensed consolidated balance sheet as of December 31, 2013 was derived from audited financial statements, but does not include all disclosures required by GAAP. Interim results are not necessarily indicative of the results to be expected for the full year or any other interim period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements as filed in the S-1 and S-1A and notes thereto included elsewhere in this quarterly report on Form 10-Q.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity(ASU 2014-08), which amended existing requirements for reporting discontinued operations. Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. The guidance is effective for disposal transactions occurring in reporting periods beginning after December 15, 2014. Presentation and disclosures of future disposal transactions after adoption of the guidance may be different than under current standards.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). Under ASU 2014-09, companies recognize revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled, in exchange for those goods or services. The new requirements significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The Company is not required to adopt this reporting standard until reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. The Company is in the process of evaluating the effect of the new guidance on our financial statements and disclosures.
