Overview	'
	1. Overview
	Basis of presentation
	Cooper-Standard Holdings Inc. (together with its consolidated subsidiaries, the “Company,” “Cooper-Standard,” “we,” “our,” or “us”) is a leading manufacturer of sealing and trim, fuel and brake delivery, fluid transfer, thermal and emissions and anti-vibration systems (“AVS”) components, systems, subsystems, and modules. The Company’s products are primarily for use in passenger vehicles and light trucks that are manufactured by global automotive original equipment manufacturers (“OEMs”) and replacement markets. The Company conducts substantially all of its activities through its subsidiaries.
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (the "2013 Annual Report"), as filed with the SEC. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. These financial statements include all adjustments (consisting of normal, recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations of the Company. Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. The operating results for the interim period ended March 31, 2014 are not necessarily indicative of results for the full year. In preparing these financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.
	Recent accounting pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 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. This ASU changes the criteria for reporting discontinued operations and requires expanded disclosures about discontinued operations. The guidance is effective for fiscal years beginning on or after December 15, 2014 and should be applied prospectively. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the condensed consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU requires that a liability related to an unrecognized tax benefit be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if certain criteria are met. The Company adopted this guidance effective January 1, 2014. The adoption of this ASU did not have a material impact on the condensed consolidated financial statements.

	Senior ABL Facility
	On April 8, 2013 the Company and certain of its subsidiaries entered into the Amended and Restated Senior Loan and Security Agreement (“the Senior ABL Facility”), with certain lenders, which amended and restated the then existing of its senior secured asset-based revolving credit facility. The Senior ABL Facility provided for an aggregate revolving loan availability of up to $150,000, subject to borrowing base availability and certain provisions of the Senior ABL Facility, including a $50,000 letter of credit sub-facility and a $25,000 swing line sub-facility. The Senior ABL Facility also provided for an uncommitted $75,000 incremental loan facility, for a potential total Senior ABL Facility of $225,000 (if requested by the Company and the lenders agree to fund such increase). No consent of any lender (other than those participating in the increase) was required to effect any such increase. As of March 31, 2014, subject to borrowing base availability under the facility, the Company had $150,000 in availability less outstanding letters of credit of $37,023.
	On April 4, 2014, the Company and certain of its subsidiaries entered into the Second Amended and Restated Loan Agreement (the "Amended Senior ABL Facility"), which amended and restated the existing Senior ABL facility in order to permit the Term Loan Facility (described below) and other related transactions and to implement other necessary conforming and administrative changes in connection with such transactions. The Amended Senior ABL Facility provides for an aggregate revolving loan availability of up to $150,000, subject to borrowing base availability and certain provisions of the Amended Senior ABL Facility, including a $60,000 letter of credit sub-facility and a $25,000 swing line sub-facility. The Amended Senior ABL Facility also provides for an uncommitted $105,000 incremental loan facility, for a potential total Amended Senior ABL Facility of $255,000 (if requested by the Company and the lenders agree to fund such increase). No consent of any lender (other than those participating in the increase) is required to effect any such increase.
	Senior PIK Toggle Notes
	On April 3, 2013, the Company issued $175,000 aggregate principal amount of its Senior PIK Toggle Notes (the “Senior PIK Toggle Notes”). The Senior PIK Toggle Notes bear an interest rate of 7.375% and mature on April 1, 2018. The Senior PIK Toggle Notes were issued pursuant to an indenture dated April 3, 2013. The Senior PIK Toggle Notes were issued at a discount of $3,938. On May 20, 2013, the Company issued an additional $25,000 Senior PIK Toggle Notes pursuant to the indenture dated April 3, 2013. The Senior PIK Toggle Notes were issued at a discount of $188.
	Prepayment of the Notes
	On March 21, 2014, the Company and Cooper-Standard Automotive Inc. commenced cash tender offers for any and all of the outstanding Senior PIK Toggle Notes and Senior Notes, respectively. Pursuant to these cash tender offers, on the early tender deadline of April 3, 2014, (i) $198,000 principal amount of the Senior PIK Toggle Notes had been tendered and not validly withdrawn, representing approximately 99.00% of the aggregate outstanding principal amount of the Senior PIK Toggle Notes and (ii) $220,328 principal amount of the Senior Notes had been tendered and not validly withdrawn, representing approximately 48.96% of the aggregate outstanding principal amount of the Senior Notes. On April 4, 2014, the Company purchased the Senior Notes and Senior PIK Toggle Notes tendered up to the early tender deadline and deposited sufficient funds with the trustee to redeem the remaining outstanding Senior Notes and Senior PIK Toggle Notes and pay accrued and unpaid interest thereon to, but not including, the redemption dates of April 21, 2014 and May 5, 2014, respectively. On April 18, 2014, the cash tender offers expired. On April 21, 2014, the Company purchased the additional Senior Notes (and Senior PIK Toggle Notes) tendered up to the expiration time and redeemed the remaining outstanding Senior Notes. The Company used borrowings under the Term Loan Facility, together with cash on hand, to finance the repurchase and redemption of the Senior PIK Toggle Notes and the Senior Notes. The approximate redemption prices for the Senior PIK Toggle Notes and the Senior Notes were 102.4% and 104.6%, respectively.
	Term Loan Facility
	On April 4, 2014, certain subsidiaries of the Company entered into a term loan facility (the “Term Loan Facility”) in order to (i) refinance the Senior PIK Toggle Notes due 2018 of the Company and the 8 1/2% Senior Notes due 2018 of Cooper-Standard Automotive Inc. (the "Senior Notes"), including applicable call premiums and accrued and unpaid interest, (ii) pay related fees and expenses and (iii) provide for working capital and other general corporate purposes. The Term Loan Facility provides for loans in an aggregate principal amount of $750,000 and may be expanded (or a new term loan facility added) by an amount that will not cause the consolidated first lien debt ratio to exceed 2.25 to 1.00 plus $300,000. All obligations of the borrower are guaranteed jointly and severally on a senior secured basis by the direct parent company of the borrower and each existing and subsequently acquired or organized direct or indirect wholly-owned U.S. restricted subsidiary of the borrower. The Term Loan Facility matures on April 4, 2021, unless earlier terminated. On April 4, 2014, the aggregate principal amount was fully drawn to refinance the Senior PIK Toggle Notes and the Senior Notes and to pay related fees and expenses.

Income Taxes	'
	7. Income Taxes
	Under ASC Topic 270, “Interim Reporting,” the Company is required to determine its effective tax rate each quarter based upon its estimated annual effective tax rate. The Company is also required to record the tax impact of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year where no tax benefit can be recognized are excluded from the estimated annual effective tax rate.
	The effective tax rate for the three months ended March 31, 2014 was 36% as compared to 28% for the three months ended March 31, 2013. The higher effective tax rate for the three months ended March 31, 2014 as compared to the three months ended March 31, 2013 is primarily due to the tax benefits related to the retroactive reinstatement of the U.S. research and development tax credit under The American Taxpayer Relief Act of 2012 which was enacted in the three months ended March 31, 2013. The income tax rate for the three months ended March 31, 2014 varies from statutory rates due to income taxes on foreign earnings taxed at rates different from the U.S. statutory rate, the inability to record a tax benefit for pre-tax losses in certain foreign jurisdictions to the extent not offset by other categories of income, tax credits, income tax incentives, withholding taxes, and other permanent items. Further, the Company’s current and future provision for income taxes may be impacted by the recognition of valuation allowances in certain countries. The Company intends to maintain these allowances until it is more likely than not that the deferred tax assets will be realized.

	Basic net income per share attributable to Cooper-Standard Holdings Inc. was computed by dividing net income attributable to Cooper-Standard Holdings Inc. by the weighted average number of shares of common stock outstanding during the period excluding unvested restricted shares. Diluted net income per share attributable to Cooper-Standard Holdings Inc. was computed using the treasury stock method by dividing diluted net income available to Cooper-Standard Holdings Inc. by the weighted average number of shares of common stock outstanding, including the dilutive effect of common stock equivalents, using the average share price during the period.

	ASC 280, “Segment Reporting,” establishes the standards for reporting information about operating segments in financial statements. The Company organized, managed and reported its global business operations through two geographic segments in the first quarter of 2013. In April 2013, the Company implemented organizational and management changes of its global business operations resulting in four reportable segments associated with geographic regions. In applying the criteria set forth in ASC 280, the Company revised its segment disclosures beginning with the second quarter of 2013 from the two reportable segments, North America and International, to four reportable segments, North America, Europe, South America and Asia Pacific. The Company’s principal product lines within each of these segments are sealing and trim systems, fuel and brake delivery systems, fluid transfer systems, thermal and emissions systems, and anti-vibration systems. The Company evaluates segment performance based on segment profit before tax. The results of each segment include certain allocations for general, administrative, interest, and other shared costs. Prior periods have been revised to conform to the current period presentation.

Fair Value Disclosures [Abstract]	'
Financial Instruments	'
	15. Financial Instruments
	Fair values of the Senior Notes approximated $477,000 and $471,375 at December 31, 2013 and March 31, 2014, respectively, based on quoted market prices, compared to the recorded value of $450,000. This fair value measurement is classified within Level 1 of the fair value hierarchy.
	Fair values of the Senior PIK Toggle Notes approximated $197,466 and $200,620 at December 31, 2013 and March 31, 2014, respectively, based on quoted market prices, compared to the recorded values of $196,484 and $196,686 at December 31, 2013 and March 31, 2014, respectively. This fair value measurement is classified within Level 1 of the fair value hierarchy.
	The Company completed an agreement with Fonds de Modernisation des Equipementiers Automobiles (“FMEA”) on May 2, 2011, to establish a joint venture that combined the Company’s French body sealing operations and the operations of Société des Polymères Barre-Thomas (“SPBT”). SPBT was a French supplier of anti-vibration systems and low pressure hoses, as well as body sealing products, which FMEA acquired as a preliminary step to the joint venture transaction. SPBT changed its name to Cooper Standard France SAS (“CS France”) subsequent to the transaction. The Company has 51% ownership and FMEA has 49% ownership in CS France. In connection with the investment in CS France, the noncontrolling shareholders have the option, which is embedded in the noncontrolling interest, to require the Company to purchase the remaining 49% noncontrolling share at a formula price designed to approximate fair value based on operating results of the entity.
	The noncontrolling interest is redeemable at other than fair value as the put value is determined based on the formula described above. The Company records the noncontrolling interest in CS France at the greater of 1) the initial carrying amount, increased or decreased for the noncontrolling shareholders’ share of net income or loss and its share of other comprehensive income or loss and dividends (“carrying amount”) or 2) the cumulative amount required to accrete the initial carrying amount to the redemption value. According to authoritative accounting guidance, the redeemable noncontrolling interest was classified outside of permanent equity, in mezzanine equity, on the Company’s condensed consolidated balance sheets.
	At December 31, 2013 and March 31, 2014, the estimated redemption value of the put option relating to the noncontrolling interest in CS France was $0. The redemption amount, if any, related to the put option is guaranteed by the Company and secured with the CS France shares held by a subsidiary of the Company. The Company has determined that the non-recurring fair value measurement related to this calculation relies primarily on Company-specific inputs and the Company’s assumptions, as observable inputs are not available. As such, the Company has determined that this fair value measurement resides within Level 3 of the fair value hierarchy. To determine the fair value of the put option, the Company utilizes the projected cash flows expected to be generated by the joint venture, then discounts the future cash flows by using a risk-adjusted rate for the Company.
	According to authoritative accounting guidance for redeemable noncontrolling shareholders’ interests, to the extent the noncontrolling shareholders have a contractual right to receive an amount upon exercise of a put option that is other than fair value, and such amount is greater than carrying value, then the noncontrolling shareholder has, in substance, received a dividend distribution that is different than other common stockholders. Therefore the redemption amount in excess of fair value should be reflected in the computation of earnings per share available to the Company’s common stockholders. At March 31, 2014 there was no difference between redemption value and fair value.
	Derivative Instruments and Hedging Activities
	The Company uses derivative financial instruments, including forward and swap contracts, to manage its exposures to fluctuations in foreign exchange and interest rates. For a fair value hedge, both the effective and ineffective, if significant, portions are recorded in earnings and reflected in the condensed consolidated statement of comprehensive income. For a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded in accumulated other comprehensive loss in the condensed consolidated balance sheet. The ineffective portion, if significant, is recorded in other income or expense. When the underlying hedged transaction is realized or the hedged transaction is no longer probable, the gain or loss included in accumulated other comprehensive loss is recorded in earnings and reflected in the condensed consolidated statement of comprehensive income on the same line as the gain or loss on the hedged item attributable to the hedged risk.
	The Company formally documents its hedge relationships, including the identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the cash flow hedges. The Company also formally assesses whether a cash flow hedge is highly effective in offsetting changes in the cash flows of the hedged item. Derivatives are recorded at fair value in other current assets and accrued liabilities.
	Cash Flow Hedges
	Forward foreign exchange contracts—The Company enters into forward contracts to hedge currency risk of the U.S. Dollar against the Mexican Peso and the Euro against the U.S. Dollar. The forward contracts are used to mitigate the potential volatility to earnings and cash flow arising from changes in currency exchange rates that impact the Company’s foreign currency transactions. As of March 31, 2014, the notional amount of these contracts was $17,326. The fair values of these contracts at March 31, 2014 were $217 in the asset position recorded in other current assets and $79 in the liability position recorded in accrued liabilities in the condensed consolidated balance sheet. The gains or losses on the forward contracts are reported as a component of accumulated other comprehensive loss and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The amount reclassified from accumulated other comprehensive loss into cost of products sold was $7 for the three months ended March 31, 2014. These foreign currency derivative contracts consist of hedges of transactions up to December 2014.
	Undesignated Derivatives
	As part of the FMEA joint venture, SPBT had undesignated derivative forward contracts to hedge currency risk of the Euro against the Polish Zloty which are included in the Company’s condensed consolidated financial statements. The forward contracts are used to mitigate the potential volatility of cash flows arising from changes in currency exchange rates that impact the Company’s foreign currency transactions. These foreign currency derivative contracts relate to hedge transactions through April 2014. As of March 31, 2014, the notional amount of these contracts was $930. At March 31, 2014, the fair value of the Company’s undesignated derivative forward contracts was a liability of $4 and is recorded in accrued liabilities in the Company’s condensed consolidated balance sheet. The unrealized gain or loss on the forward contracts is reported as a component of other income (expense), net. The unrealized loss amounted to $188 and $38 for the three months ended March 31, 2013 and 2014, respectively.
	Fair Value Measurements
	ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
	Level 1:		Observable inputs such as quoted prices in active markets;
	Level 2:		Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
	Level 3:		Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	Estimates of the fair value of foreign currency and interest rate derivative instruments are determined using exchange traded prices and rates. The Company also considers the risk of non-performance in the estimation of fair value, and includes an adjustment for non-performance risk in the measure of fair value of derivative instruments. In certain instances where market data is not available, the Company uses management judgment to develop assumptions that are used to determine fair value. Fair value measurements and the fair value hierarchy level for the Company’s liabilities measured or disclosed at fair value on a recurring basis as of December 31, 2013 and March 31, 2014, are shown below:
		December 31, 2013			March 31, 2014			Input
	Forward foreign exchange contracts - other current assets	$	36		$	217		Level 2
	Forward foreign exchange contracts - accrued liabilities	(1		)	(83		)	Level 2
	Items measured at fair value on a non-recurring basis
	In addition to items that are measured at fair value on a recurring basis, the Company measures certain assets and liabilities at fair value on a non-recurring basis, which are not included in the table above. As these non-recurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. For further information on assets and liabilities measured at fair value on a non-recurring basis, see Note 3. “Restructuring.”

	Cooper-Standard Holdings Inc. (together with its consolidated subsidiaries, the “Company,” “Cooper-Standard,” “we,” “our,” or “us”) is a leading manufacturer of sealing and trim, fuel and brake delivery, fluid transfer, thermal and emissions and anti-vibration systems (“AVS”) components, systems, subsystems, and modules. The Company’s products are primarily for use in passenger vehicles and light trucks that are manufactured by global automotive original equipment manufacturers (“OEMs”) and replacement markets. The Company conducts substantially all of its activities through its subsidiaries.
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (the "2013 Annual Report"), as filed with the SEC. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. These financial statements include all adjustments (consisting of normal, recurring adjustments) considered necessary for a fair presentation of the financial position and results of operations of the Company. Certain prior period amounts have been reclassified to conform to the current period financial statement presentation. The operating results for the interim period ended March 31, 2014 are not necessarily indicative of results for the full year. In preparing these financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.

	Recent accounting pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 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. This ASU changes the criteria for reporting discontinued operations and requires expanded disclosures about discontinued operations. The guidance is effective for fiscal years beginning on or after December 15, 2014 and should be applied prospectively. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the condensed consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU requires that a liability related to an unrecognized tax benefit be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if certain criteria are met. The Company adopted this guidance effective January 1, 2014. The adoption of this ASU did not have a material impact on the condensed consolidated financial statements.
