	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, 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 June 30, 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.
	Disposition
	In June 2014, the Company entered into an agreement to sell its thermal and emissions product line, which will allow the Company to focus on its four core product groups. The sale closed in the third quarter of 2014. As of June 30, 2014, the Company had reclassified approximately $25,000, primarily consisting of property, plant and equipment, net to other current assets as assets held for sale. The assets held for sale consist of approximately $15,000 and $10,000 relating to the North America and Europe segments, respectively. This disposition does not meet the discontinued operations criteria.
	Recent accounting pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of this guidance is that a company should recognize revenue to depict the transfer of promised goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The guidance is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. The guidance allows for companies to use either a full retrospective or a modified retrospective approach when adopting. The Company is currently evaluating the impact of adopting this guidance on its condensed consolidated financial statements.
	In April 2014, FASB issued 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 “Amended Senior ABL Facility”), with certain lenders, which amended and restated the then existing senior secured asset-based revolving credit facility of the Company, dated May 27, 2010. The Amended Senior ABL Facility provided for an aggregate revolving loan availability of up to $150,000, subject to borrowing base availability, including a $50,000 letter of credit sub-facility and a $25,000 swing line sub-facility. The Amended Senior ABL Facility also provided for an uncommitted $75,000 incremental loan facility, for a potential total Amended Senior ABL Facility of $225,000 (if requested by the Company and one or more new or existing lenders agreed to fund such increase).
	On April 4, 2014, the Company and certain of its subsidiaries entered into the Second Amended and Restated Loan Agreement (the "Senior ABL Facility"), which amended and restated the Amended Senior ABL Facility, in order to permit the Term Loan Facility (described below) and other related transactions. The Senior ABL Facility continues to provide for an aggregate revolving loan availability of up to $150,000, subject to borrowing base availability, including a $60,000 letter of credit sub-facility and the same $25,000 swing line sub-facility. The Senior ABL Facility also provided for an uncommitted $105,000 incremental loan facility, for a potential total Senior ABL Facility of $255,000 (if requested by the Company and one or more new or existing lenders agreed to fund such increase). The obligations under the Senior ABL Facility are secured by amongst other items (a) a first priority security interest in accounts receivable of the U.S. borrower and the U.S. guarantors arising from the sale of goods and services, and inventory, excluding certain property and subject to certain limitations (with obligations of the Canadian borrower secured also by comparable assets of the Canadian borrower and Canadian guarantors) and (b) a second priority security interest (subject to permitted liens and other customary exceptions) on (i) all the capital stock in restricted subsidiaries directly held by the U.S. borrower and each of the U.S. guarantors, (ii) substantially all material owned real property located in the U.S. and equipment of the U.S. borrower and the U.S. guarantors and (iii) all other material personal property of the U.S. borrower and the U.S. guarantors.
	On June 11, 2014, the Company and certain of its subsidiaries entered into Amendment No. 1 to the Senior ABL Facility, which increased the aggregate revolving loan availability to $180,000, subject to borrowing base availability, principally by expanding a tooling receivable category of eligible borrowing base availability for the U.S. borrower and Canadian borrower. The Senior ABL Facility, as amended, also now provides for an uncommitted $75,000 incremental loan facility, for a potential total Senior ABL Facility of $255,000 (if requested by the Company and one or more new or existing 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. As of June 30, 2014, subject to borrowing base availability, the Company had $180,000 in availability under the Senior ABL Facility supporting outstanding letters of credit of $35,576,465.
	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 obligations are secured by amongst other items (a) a first priority security interest (subject to permitted liens and other customary exceptions) on (i) all the capital stock in restricted subsidiaries directly held by the borrower and each of the guarantors, (ii) substantially all plant, material owned real property located in the U.S. and equipment of the borrower and the guarantors and (iii) all other personal property of the borrower and the guarantors, and (b) a second priority security interest (subject to permitted liens and other customary exceptions) in accounts receivable of the borrowers and the guarantors arising from the sale of goods and services, inventory, excluding certain collateral and subject to certain limitations. Loans under the Term Loan Facility bear interest at a rate equal to, at the Borrower’s option, LIBOR, subject to a 1.00% LIBOR Floor or the base rate option (the highest of the Federal Funds rate, prime rate, or one-month Eurodollar rate plus the appropriate spread), in each case, plus an applicable margin of 3.00%. The Term Loan Facility matures on April 4, 2021. On April 4, 2014, the aggregate principal amount of $750,000 was fully drawn to extinguish the Senior PIK Toggle Notes and the Senior Notes and to pay related fees and expenses. As of June 30, 2014, the entire principle amount of $750,000 was outstanding. Debt issuance costs of approximately $7,900 were incurred on this transaction, along with the original issue discount of $3,750. Both the debt issuance costs and the original issue discount will be amortized into interest expense over the term of the Term Loan Facility. As of June 30, 2014, the Company had $3,616 of unamortized original issue discount.
	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. Approximately 99% of the Senior PIK Toggle Notes and 49% of the Senior Notes were tendered and purchased on April 4, 2014, and the funds to redeem the remainder were deposited with the Trustee. The remaining redemptions were completed on April 21, 2014 for the Senior Notes and May 5, 2014 for the Senior PIK Toggle Notes.
	As a result of the purchases and redemptions, the Company recognized a loss on extinguishment of $30,488 in the six months ended June 30, 2014, which was primarily due to call and make-whole premiums and the write off of approximately $4,500 in original issue discount and debt issuance costs.
	The Company used borrowings under the Term Loan Facility (described above), together with cash on hand, to finance the repurchase and redemption of the Senior PIK Toggle Notes and the Senior Notes.

Income Tax Disclosure [Abstract]	'
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 and six months ended June 30, 2014 was 24% and 32%, respectively. The effective tax rate for the three and six months ended June 30, 2013 was 32% and 30%, respectively. The effective tax rate for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013 is lower primarily due to the tax benefits related to the loss on extinguishment of debt recorded as a discrete item in the three months ended June 30, 2014. The higher effective tax rate for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 is primarily a result of the U.S. research and development tax credit not reenacted for 2014; therefore it is not reflected as a benefit in the 2014 effective tax rate. The higher effective tax rate was partly offset by the impacts of the tax benefits related to the loss on extinguishment of debt recorded as a discrete item in the three months ended June 30, 2014. The income tax rate for the three and six months ended June 30, 2014 varies from statutory rates due to the impact of discrete items in the quarter, income taxes on foreign earnings taxed at rates lower than 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. In applying the criteria set forth in ASC 280, the Company has determined that it operates in 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.

Financial Instruments	'
	14. Financial Instruments
	Fair value of the Senior Notes approximated $477,000 at December 31, 2013, based on quoted market prices, compared to the recorded value of $450,000. During the second quarter 2014, the Company extinguished its Senior Notes (see Note 5. "Debt" for additional details). This fair value measurement was classified within Level 1 of the fair value hierarchy.
	Fair value of the Senior PIK Toggle Notes approximated $197,466 at December 31, 2013, based on quoted market prices, compared to the recorded value of $196,484. During the second quarter 2014, the Company extinguished its Senior PIK Toggle Notes (see Note 5. "Debt" for additional details). This fair value measurement was 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 June 30, 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 June 30, 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, the Danish Krone against the Euro, the Polish Zloty against the Euro, and the Euro against the Romanian Lue and 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 June 30, 2014, the notional amount of these contracts was $32,547. The fair values of these contracts at June 30, 2014 were $258 in the asset position recorded in other current assets and $78 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 $81 and $74 for the three and six months ended June 30, 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 were used to mitigate the potential volatility of cash flows arising from changes in currency exchange rates that impacted the Company’s foreign currency transactions. These foreign currency derivative contracts related to hedge transactions through April 2014. The unrealized gain or loss on the forward contracts is reported as a component of other income (expense), net. The unrealized gain (loss) amounted to ($305) and $4 for the three months ended June 30, 2013 and 2014, respectively, and ($493) and $(34), for the six months ended June 30, 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 June 30, 2014, are shown below:
		December 31, 2013			June 30, 2014			Input
	Forward foreign exchange contracts - other current assets	$	36		$	258		Level 2
	Forward foreign exchange contracts - accrued liabilities	(1		)	(78		)	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.”

	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, 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 June 30, 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	'
	Recent accounting pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of this guidance is that a company should recognize revenue to depict the transfer of promised goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The guidance is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. The guidance allows for companies to use either a full retrospective or a modified retrospective approach when adopting. The Company is currently evaluating the impact of adopting this guidance on its condensed consolidated financial statements.
	In April 2014, FASB issued 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.
