Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Stoneridge, Inc. and its wholly-owned and majority-owned subsidiaries (collectively, the “Company”).  Intercompany transactions and balances have been eliminated in consolidation.  The Company analyzes its ownership interests in accordance with Accounting Standards Codification “ASC” Topic 810 to determine whether they are VIE’s and, if so, whether the Company is the primary beneficiary.  The Company’s investment in Minda Stoneridge Instruments Ltd. (“Minda”) at December 31, 2013, 2012 and 2011 was determined under the provisions of ASC Topic 810 to be an unconsolidated entity and was accounted for under the equity method of accounting based on our 49% noncontrolling interest.
	On December 31, 2011, the Company completed the acquisition of an additional 24% controlling interest in PST Eletrônica Ltda. (“PST”).     As a result, the Company owns 74% of the outstanding equity of PST.
	PST’s results for the years ended December 31,  2013 and 2012 were consolidated such that 100% of PST’s operations were included in each line from net sales through net income in the Company’s consolidated statements of operations with the 26% noncontrolling interest reduced (increased) in the net income (loss) attributable to noncontrolling interest line.
	PST’s results for the year ended December 31, 2011 were accounted for as an unconsolidated joint venture under the equity method of accounting such that our 50% portion of PST’s after-tax earnings were included within equity in earnings of investees in the consolidated statements of operations as a controlling interest in PST was not acquired until the close of business on December 31, 2011.
	Accounting Estimates
	The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including certain self-insured risks and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Because actual results could differ from those estimates, the Company revises its estimates and assumptions as new information becomes available.
	Cash and Cash Equivalents
	The Company’s cash and cash equivalents are actively traded money market funds with short-term investments in marketable securities, primarily U.S. government securities. Cash and cash equivalents are stated at cost, which approximates fair value, due to the highly liquid nature and short-term duration of the underlying securities.
	Accounts Receivable and Concentration of Credit Risk
	Revenues are principally generated from the commercial, automotive, agricultural, motorcycle and off-highway vehicle markets.  The Company’s largest customers were Deere & Company (“Deere”) and Navistar International Corporation (“Navistar”), primarily related to the Wiring reportable segment, and accounted for the following percentages of consolidated net sales for the years ended December 31, 2013, 2012 and 2011:
			2013			2012			2011
	Deere		14	%		13	%		15	%
	Navistar		13	%		18	%		24	%
	Accounts receivable are recorded at the invoice price net of an estimate of allowance for doubtful accounts and other reserves.
	Allowance for Doubtful Accounts
	The Company evaluates the collectability of accounts receivable based on a combination of factors.  In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations, a specific allowance for doubtful accounts is recorded against amounts due to reduce the net recognized receivable to the amount the Company reasonably believes will be collected.  Additionally, the Company reviews historical trends for collectability in determining an estimate for its allowance for doubtful accounts.  If economic circumstances change substantially, estimates of the recoverability of amounts due to the Company could be reduced by a material amount.  The Company does not have collateral requirements with its customers.
	Inventories
	Inventories are valued at the lower of cost (using either the first-in, first-out (“FIFO”) or average cost methods) or market.  The Company evaluates and adjusts as necessary its excess and obsolescence reserve on a quarterly basis.  Excess inventories are quantities of items that exceed anticipated sales or usage for a reasonable period.  The Company has guidelines for calculating provisions for excess inventories based on the number of months of inventories on hand compared to anticipated sales or usage.  Management uses its judgment to forecast sales or usage and to determine what constitutes a reasonable period.  Inventory cost includes material, labor and overhead. Inventories consist of the following:
	As of December 31			2013		2012
	Raw materials		$	71,631	$	64,340
	Work-in-progress			16,168		13,621
	Finished goods			26,259		18,071
	Total inventories, net		$	114,058	$	96,032
	Inventory valued using the FIFO method was $67,750 and $57,004 at December 31, 2013 and 2012, respectively.  Inventory valued using the average cost method was $46,308 and $39,028 at December 31, 2013 and 2012, respectively.
	Pre-production Costs Related to Long-term Supply Arrangements
	Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer.  Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company either has title to the assets or has the noncancelable right to use the assets during the term of the supply arrangement are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years.  Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee to a lump sum reimbursement from the customer are capitalized as a component of prepaid expenses and other current assets within the consolidated balance sheets.  The amounts recorded related to these pre-production costs as of December 31, 2013 and 2012 were $12,944 and $8,631, respectively.
	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost and consist of the following:
	As of December 31			2013		2012
	Land and land improvements		$	4,861	$	5,117
	Buildings and improvements			43,630		45,940
	Machinery and equipment			208,243		196,003
	Office furniture and fixtures			8,351		8,856
	Tooling			70,050		71,045
	Information technology			33,759		33,009
	Vehicles			426		1,456
	Leasehold improvements			3,447		3,560
	Construction in progress			14,336		17,656
	Total property, plant, and equipment			387,103		382,642
	Less: accumulated depreciation			-276,231		-263,495
	Property, plant and equipment, net		$	110,872	$	119,147
	Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Depreciation expense for the years ended December 31, 2013, 2012 and 2011 was $28,989,  $28,519 and $18,847, respectively. Depreciable lives within each property classification are as follows:
	Buildings and improvements			10-40 years
	Machinery and equipment			3-10 years
	Office furniture and fixtures			3-10 years
	Tooling			2-5 years
	Information technology			3-5 years
	Vehicles			3-5 years
	Leasehold improvements	shorter of lease term or 3-10 years
	Maintenance and repair expenditures that are not considered improvements and do not extend the useful life of the property, plant and equipment are charged to expense as incurred.  Expenditures for improvements and major renewals are capitalized.  When assets are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts, and any gain or loss on the disposition is recorded in the consolidated statements of operations as a component of selling, general and administrative expenses.
	Impairment of Long-Lived or Finite-Lived Assets
	The Company reviews the carrying value of its long-lived assets and finite-lived intangible assets for impairment when events or circumstances indicate that their carrying value may not be recoverable.  Factors the Company considers important that could trigger testing of the related asset groups for an impairment include current period operating or cash flow losses combined with a history of operating or cash flow losses, a projection or forecast that demonstrates continuing losses, significant adverse changes in the business climate within a particular business or current expectations that a long-lived asset will be sold or otherwise disposed of significantly before the end of its estimated useful life.  To test for impairment, the estimated undiscounted cash flows expected to be generated from the use and disposal of the asset or asset group is compared to its carrying value.  An asset group is established by identifying the lowest level of cash flows generated by the group of assets that are largely independent of cash flows of other assets.  If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the group of assets for which we can identify projected cash flows.  If these undiscounted cash flows are less than their respective carrying values, an impairment charge would be recognized to the extent that the carrying values exceed estimated fair values.  Although third-party estimates of fair value are utilized when available, the estimation of undiscounted cash flows and fair value requires us to make assumptions regarding future operating results.  The results of the impairment testing are dependent on these estimates which require judgment.  The occurrence of certain events, including changes in economic and competitive conditions, could impact cash flows eventually realized and management’s ability to accurately assess whether an asset is impaired.
	During the year ended December 31, 2011, the Company recorded an impairment charge of $807 in its Wiring reportable segment related to certain capitalized software costs that were determined to no longer represent a future realizable benefit.  This charge is recorded in the consolidated statements of operations as a component of selling, general and administrative expenses.  No material impairment charges were recorded in 2013 or 2012 for long-lived or finite-lived intangible assets.
	Acquisitions
	PST Eletrônica Ltda.
	On December 31, 2011, the Company acquired a controlling interest in PST, by increasing its interest from 50% to 74%.  Prior to the acquisition of the additional interest, the PST joint venture was accounted for under the equity method of accounting.  On the date of acquisition of controlling interest, PST became a consolidated subsidiary and a new reportable segment of the Company.   PST’s results of operations were consolidated and included in the Company’s consolidated statements of operations, comprehensive income and cash flows for the year ended December 31, 2013 and 2012.  For the year ended December 31, 2011, PST’s results of operations and cash flows were included in the Company’s consolidated statements of operations and cash flows as equity in earnings of investees.  PST’s financial position is included in the consolidated balance sheets at December 31, 2013 and 2012.
	As a result of obtaining a controlling interest in PST, the Company’s previously held 50% equity interest in PST of $38,746 was remeasured to an acquisition date fair value of $104,118.  The Company recognized a one-time non-cash pre-tax gain on previously held equity interest of $65,372 as a result of this remeasurment in the fourth quarter of 2011.
	The acquisition date fair value of the total consideration transferred consisted of the following:
	Cash	$	29,669
	Common Shares (1,940,413 shares)		15,310
	Fair value of consideration transferred		44,979
Fair value of the Company's previously held equity interest		104,118
Fair value of noncontrolling interest		48,727
Total fair value of PST	$	197,824
Of the $44,979 consideration transferred for the additional 24% interest, $29,976 ($19,779 of cash and $10,197 of the fair value of 1,293,609 Company Common Shares) was transferred on January 5, 2012, in accordance with the terms of the purchase agreement.
The fair value of the Common Shares transferred was based on the closing market price of the Company’s Common Shares on the acquisition date, less a discount for a lack of short-term marketability as the Common Shares transferred were issued through a private placement.
Goodwill of $67,118 was calculated as the excess of the fair value of consideration transferred over the fair market value of the identifiable assets and liabilities and represents the future economic benefits arising from other assets acquired that could not be separately recognized.  Goodwill is reported in the Company’s PST segment and is not deductible for income tax purposes.
The Company identified $97,398 of intangible assets that include; $47,126 assigned to customer lists with a 15 year useful life; $31,400 assigned to trademarks with a 20 year useful life; and $18,872 assigned to technology with a 17 year weighted-average useful life.  The fair value of the identifiable intangible assets was determined using an income approach.
The following unaudited pro forma information reflects the Company’s consolidated results of operations as if the acquisition had occurred on January 1, 2011. The unaudited pro forma information is not necessarily indicative of the results of operations that the Company would have reported had the transaction actually occurred at the beginning this period, nor is it necessarily indicative of future results.
Years ended December 31		2011
Net sales		$          999,553
Net income attributable to Stoneridge, Inc.		$            10,608
The unaudited pro forma financial information presented in the table above has been adjusted to give effect to adjustments that are directly related to the business combination and factually supportable. These tax affected adjustments include, but are not limited to depreciation and amortization related to fair value adjustments to property, plant, and equipment, intangible assets and inventory.
Bolton Conductive Systems, LLC
On October 13, 2009, the Company acquired a 51% controlling interest in Bolton Conductive Systems, LLC (“BCS”) for a purchase price of $5,967, net of cash acquired.  BCS designs and manufactures a wide variety of electrical solutions for the military, automotive, marine and specialty vehicle markets. The Company purchased the remaining 49% noncontrolling interest in BCS in February 2013 for a nominal amount, which was treated as an equity transaction.
During the period from February 2013 through December 2013, 100% of BCS results of operations were included in the Company’s consolidated statements of operations.  During the years ended December 31, 2012 and 2011, 49% of BCS’s results were included within loss attributable to noncontrolling interest within the consolidated statements of operations.
Goodwill and Other Intangible Assets
The total purchase price associated with acquisitions is allocated to the acquisition date fair values of identifiable assets acquired and liabilities assumed, with the excess purchase price assigned to goodwill.
In 2011, the Company recorded goodwill of $67,118 related to the acquisition of PST (see Acquisitions above).  In 2009, the Company recorded goodwill of $9,118 within the Wiring segment related to the BCS acquisition. The goodwill related to these acquisitions is not deductible for income tax purposes.  The remainder of the December 31, 2013 and 2012 goodwill balance relates to the 2008 acquisition of Magnum Trade AB, which is included within the Electronics segment.
Goodwill as of December 31, 2013 and 2012, and changes in the carrying amount of goodwill by segment were as follows:
						Control
		Electronics		Wiring		Devices		PST		Total
Balance at January 1, 2012	$	564	$	4,173	$	-	$	67,118	$	71,855
Currency translation		34		-		-		-5,508		-5,474
Balance at December 31, 2012		598		4,173		-		61,610		66,381
Currency translation		6		-		-		-7,866		-7,860
Balance at December 31, 2013	$	604	$	4,173	$	-	$	53,744	$	58,521
Goodwill is subject to an annual assessment for impairment (or more frequently if impairment indicators arise) by applying a fair value-based test.
The Company performed its annual impairment test of goodwill as of the beginning of the fourth quarter.  The Company utilized an income approach (discounted cash flow method) valuation technique in determining the fair value of the Company’s applicable reporting units in the annual impairment test of goodwill. The discounted cash flow method utilizes a market-derived rate of return to discount anticipated performance.
The income approach methodology is applied to the reporting units’ projected future financial performance.  The impairment review is highly judgmental and involves the use of significant estimates and assumptions.   These estimates and assumptions have a significant impact on the amount of impairment charge recorded, if any.   The discounted cash flow method is dependent upon assumption of future sales trends, market conditions and cash flows of each reporting unit over several years.  Actual cash flows in the future may differ significantly from those previously forecasted.  Other significant assumptions include growth rates and the discount rate applicable to future cash flows.
During the year ended December 31, 2011, the Company recorded a goodwill impairment charge of $4,945 within the Wiring reportable segment.  The goodwill impairment charge reduced the carrying value of BCS goodwill to $4,173 and was the result of a decline in business activity due to a reduction in military and defense related spending by customers since the Company’s acquisition of BCS.  No impairment was identified in the Wiring segment for the years ended December 31, 2013 or 2012.
The Company’s accumulated goodwill impairment loss for the years ended December 31, 2013 and 2012 was $253,570.
Intangible assets, net at December 31, 2013 and 2012 consisted of the following:
		Acquisition		Accumulated
As of December 31, 2013		cost		amortization		Net
Customer lists	$	38,451	$	-5,402	$	33,049

Total	$	90,614	$	-6,217	$	84,397
The Company recognized $5,275,  $5,940 and $238 of amortization expense in 2013, 2012 and 2011, respectively.  Amortization expense is included as a component of selling, general and administrative on the consolidated statements of operations.  Amortization expense for intangible assets is estimated to be approximately $5,000 for the years 2014 through 2019 and the weighted-average remaining amortization period is approximately 15 years.
Accrued Expenses and Other Current Liabilities
Accrued expenses and other current liabilities consist of the following:
As of December 31		2013		2012
Compensation related liabilities	$	24,631	$	22,620
Product warranty and recall obligations		5,462		5,613
Other (A)		26,558		28,848
Total accrued expenses and other current liabilities	$	56,651	$	57,081
(A)“Other” is comprised of miscellaneous accruals, none of which contributed a significant portion of the total.
Income Taxes
The Company accounts for income taxes using the liability method. Deferred income taxes reflect the tax consequences on future years of differences between the tax basis of assets and liabilities and their financial reporting amounts. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not to occur.
The Company's policy is to provide for uncertain tax positions and the related interest and penalties based upon management's assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities.  At December 31, 2013, the Company believes it has appropriately accounted for any unrecognized tax benefits (see Note 5).  To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company's effective tax rate in a given financial statement period may be affected.
Currency Translation
The financial statements of foreign subsidiaries, where the local currency is the functional currency, are translated into U.S. dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for the results of operations.  Adjustments resulting from translation of financial statements are reflected as a component of accumulated other comprehensive loss.  Foreign currency transactions are remeasured into the functional currency using translation rates in effect at the time of the transaction, with the resulting adjustments included on the consolidated statements of operations within other expense, net.  These foreign currency transaction losses, including the impact of hedging activities, were $1,752,  $4,275 and $106 for the years ended December 31, 2013, 2012 and 2011, respectively.
Revenue Recognition and Sales Commitments
The Company recognizes revenues from the sale of products, net of actual and estimated returns, at the point of passage of title, which is either at the time of shipment or upon customer receipt based upon the terms of the sale.  The Company collects certain taxes and fees on behalf of government agencies and remits such collections on a periodic basis.  The taxes are collected from customers but are not included in net sales. Estimated returns are based on historical authorized returns.  The Company often enters into agreements with its customers at the beginning of a given vehicle’s expected production life.  Once such agreements are entered into, it is the Company’s obligation to fulfill the customers’ purchasing requirements for the entire production life of the vehicle.  These agreements are subject to renegotiation, which may affect product pricing.
Shipping and Handling Costs
Shipping and handling costs are included in cost of goods sold on the consolidated statements of operations.
Product Warranty and Recall Reserves
Amounts accrued for product warranty and recall claims are established based on the Company’s best estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet dates.  These accruals are based on several factors including past experience, production changes, industry developments and various other considerations.  The Company can provide no assurances that it will not experience material claims in the future or that it will not incur significant costs to defend or settle such claims beyond the amounts accrued or beyond what the Company may recover from its suppliers.  The current portion of the product warranty and recall reserve is included as a component of accrued expenses and other current liabilities on the consolidated balance sheets.  Product warranty and recall includes $1,019 and $494 of a long-term liability at December 31, 2013 and 2012, respectively, which is included as a component of other long-term liabilities on the consolidated balance sheets.
The following provides a reconciliation of changes in the product warranty and recall reserve:
Years ended December 31		2013		2012
Product warranty and recall at beginning of period	$	6,107	$	5,301
Accruals for products shipped during period		4,793		3,288
Aggregate changes in pre-existing liabilities due to claim developments		1,715		1,062
Settlements made during the period (in cash or in kind)		-6,134		-3,544
Product warranty and recall at end of period	$	6,481	$	6,107
Product Development Expenses
Expenses associated with the development of new products and changes to existing products are charged to expense as incurred and are included in the Company’s consolidated statements of operations as a component of selling, general and administrative.  These product development costs amounted to $45,261,  $44,798 and $35,263 in years ended December 31, 2013, 2012 and 2011, respectively, or 4.8%,  4.8% and 4.6% of net sales for these respective periods.
Share-Based Compensation
At December 31, 2013, the Company had three types of share-based compensation plans: (1) Long-Term Incentive Plan, as amended, (2) Directors’ Share Option Plan and (3) the Amended Directors’ Restricted Shares Plan.  One plan is for employees and two plans are for non-employee directors.  The Long-Term Incentive Plan is made up of the Long-Term Incentive Plan that was approved by the Company's shareholders on September 30, 1997, which expired on June 30, 2007, and the Amended and Restated Long-Term Incentive Plan, as amended, that was approved by shareholders on May 17, 2010, and expires on April 24, 2016.
Total compensation expense recognized as a component of selling, general and administrative on the consolidated statements of operations for share-based compensation arrangements was $4,974,  $4,890 and $4,423 for the years ended December 31, 2013, 2012 and 2011, respectively.  Of these amounts, $155,  $47 and $375 for the years ended December 31, 2013, 2012 and 2011, respectively, were related to the Long-Term Cash Incentive Plan “Phantom Shares” discussed in Note 8.  There was no share-based compensation expense capitalized in inventory during 2013, 2012 or 2011.
Financial Instruments and Derivative Financial Instruments
Financial instruments, including derivative financial instruments, held by the Company include cash and cash equivalents, accounts receivable, accounts payable, long-term debt, an interest rate swap, fixed price commodity contracts and foreign currency forward contracts. The carrying value of cash and cash equivalents, accounts receivable and accounts payable is considered to be representative of fair value because of the short maturity of these instruments.  See Note 9 for fair value disclosures of the Company’s financial instruments.
Common Shares Held in Treasury
The Company accounts for Common Shares held in treasury under the cost method and includes such shares as a reduction of total shareholders’ equity.
Net Income Per Share
Basic net income per share was computed by dividing net income by the weighted-average number of Common Shares outstanding for each respective period.  Diluted net income per share was calculated by dividing net income by the weighted-average of all potentially dilutive Common Shares that were outstanding during the periods presented.
Actual weighted-average Common Shares outstanding used in calculating basic and diluted net income per share were as follows:
Years ended December 31		2013		2012		2011
Basic weighted-average shares outstanding		26,670,501		26,377,352		24,180,671
Effect of dilutive securities		522,984		654,518		464,258
Diluted weighted-average shares outstanding		27,193,485		27,031,870		24,644,929
Options not included in the computation of diluted net income per share to purchase 20,000,  59,000 and 50,000 Common Shares at an average price of $15.73,  $12.20 and $15.73 per share were outstanding at December 31, 2013, 2012 and 2011, respectively.  These outstanding options were not included in the computation of diluted net income per share because their respective exercise prices were greater than the average closing market price of Company Common Shares.
There were 663,750,  635,850 and 419,100 performance-based restricted Common Shares outstanding at December 31, 2013, 2012 and 2011, respectively. These shares were not included in the computation of diluted net income per share because all vesting conditions have not been and are not expected to be achieved as of December 31, 2013, 2012 and 2011.  These shares may become dilutive based on the Company’s ability to meet or exceed future performance targets.
Deferred Finance Costs
Deferred finance costs are being amortized over the life of the related financial instrument using the straight-line method, which approximates the effective interest method.  The 2.5% discount to the initial purchasers of the Company’s senior secured notes is being accreted using the effective interest rate of 10.0% over the life of the senior secured notes. Deferred finance cost amortization and debt discount accretion for the years ended December 31, 2013, 2012 and 2011 was $961,  $862 and $875, respectively, and is included as a component of interest expense, net on the consolidated statements of operations.  As of December 31, 2013 and 2012, deferred financing costs, net were $1,168 and $1,564, respectively and were included on the consolidated balance sheets as a component of investments and other long-term assets, net.
Changes in Accumulated Other Comprehensive Loss by Component
Changes in accumulated other comprehensive loss for the years ended December 31, 2013 and 2012 were as follows:
		Foreign				Benefit

Recently Adopted Accounting Standards
In February 2013, the Financial Accounting Standards Board ("FASB") issued an accounting standards update requiring new disclosures about reclassifications from accumulated other comprehensive loss to net income. These disclosures may be presented on the face of the statements or in the notes to the consolidated financial statements. The standards update is effective for fiscal years beginning after December 15, 2012. We adopted this standards update on January 1, 2013 and revised our disclosures, see above.
In December 2011, the FASB issued an accounting standards update requiring new disclosures about financial instruments and derivative instruments that are either offset by or subject to an enforceable master netting arrangement or similar agreement. The standards update is effective for fiscal years beginning after December 15, 2012. We adopted this standards update on January 1, 2013 which had no impact on our disclosures.
Reclassifications
Certain prior period amounts have been reclassified to conform to their 2013 presentation in the consolidated financial statements.

	Revolving Credit Facilities
	On November 2, 2007, the Company entered into an asset-based credit facility (the “Credit Facility”), which permits borrowing up to a maximum level of $100,000.  The Company entered into an Amended and Restated Credit and Security Agreement and a Second Amended and Restated Credit and Security Agreement (the “Second Amended and Restated Agreement”) on September 20, 2010 and December 1, 2011, respectively.  The Second Amended and Restated Agreement extended the termination date of the Credit Facility to December 1, 2016, increased the borrowing base by increasing the sublimit on eligible inventory located at Mexican facilities and made changes to certain covenants relating to, among other things, guarantees, investments, capital expenditures and permitted indebtedness.  The Credit Facility requires a commitment fee of 0.375% on the unused balance.  Interest is payable quarterly at either (i) the higher of the prime rate or the Federal Funds rate plus 0.50%, plus a margin of 0.00% to 0.25% or (ii) LIBOR plus a margin of 1.00% to 1.75%, depending upon the Company’s undrawn availability, as defined.
	The available borrowing capacity on the Credit Facility is based on eligible current assets, as defined.  At December 31, 2013 and 2012, the Company had undrawn borrowing capacity of approximately $71,072 and $74,060, respectively, based on eligible current assets.  The Credit Facility contains financial performance covenants which would only constrain the Company’s borrowing capacity if our undrawn availability falls below $20,000.  However, restrictions include limits on capital expenditures, operating leases, dividends and investment activities in a negative covenant which limits investment activities to $15,000 minus certain guarantees and obligations.
	The Company was in compliance with all Credit Facility covenants at December 31, 2013 and 2012.
	On October 13, 2009, BCS entered into a master revolving note (the "BCS Revolver"), subject to an annual renewal, which permitted borrowing up to a maximum level of $3,000. At December 31, 2012, the Company had outstanding borrowings under this facility of $1,160 and did not have any remaining borrowing capacity based on an advance formula, as defined.  The BCS Revolver was paid off and the agreement was terminated in February 2013.

	Total provision for income taxes	$	4,226	$	812	$	26,105
	A reconciliation of the Company’s effective income tax rate to the statutory federal tax rate is as follows:
	Years ended December 31		2013		2012		2011
	Statutory U.S. deferal income tax rate		35.0	%	35.0	%	35.0	%

	Other		-0.8		1.3		1.7
	Effective income tax rate		20.4	%	17.8	%	36.4	%
	The Company recognized a provision for income taxes of $4,226 or 20.4%,  $812 or 17.8% and $26,105 or 36.4% of income before income tax for federal, state and foreign income taxes for the years ended December 31, 2013, 2012 and 2011, respectively. The increase in tax expense for the year ended December 31, 2013 compared to the same period for 2012 was related to the improved financial performance of our Swedish and Brazilian operations. The results of our U.S. operations do not impact tax expense due to the valuation allowance. However, the income or loss of the U.S. operations does impact the effective tax rate. The effective tax rate for 2013 increased primarily due to a decline in the financial performance of the U.S. operations.
	A deferred tax liability of $456 has been recorded related to earnings that are not considered indefinitely reinvested related to Brazil.  The Company has not recorded deferred income taxes on the remaining undistributed earnings of its foreign subsidiaries because of management’s intent and ability to indefinitely reinvest such earnings. At December 31, 2013 the aggregate undistributed earnings of our foreign subsidiaries amounted to $27,509  The Company may be subject to U.S. income taxes and foreign withholding taxes if these earnings were distributed. It is not practical to estimate the amount of taxes, if any, that may be payable on these earnings as that estimate depends upon circumstances that would exist at the time a remittance occurs.
	Significant components of the Company’s deferred tax assets and liabilities were as follows:
	As of December 31		2013		2012
	Deferred tax assets:
	Inventories	$	2,943	$	3,200
	Employee salary and benefits		3,653		3,860
	Insurance		489		562
	Depreciation and amortization		2,359		10,029
	Net operating loss carryforwards		45,859		39,834
	General business credit carryforwards		12,900		11,897
	Reserves not currently deductible		8,883		9,643
	Gross deferred tax assets		77,086		79,025
	Less: Valuation allowance		(71,827)		(71,790)
	Deferred tax assets less valuation allowance		5,259		7,235
	Deferred tax liabilities:
	Depreciation and amortization		(23,718)		(29,615)
	Basis difference - equity investee		(31,016)		(31,016)
	Other		(1,764)		(4,315)
	Gross deferred tax liabilities		(56,498)		(64,946)
	Net deferred tax liability	$	(51,239)	$	(57,711)
	The Company has concluded based on objective evidence that at December 31, 2013 and 2012 it is more likely than not that sufficient taxable income will not be generated to utilize the remaining U.S. federal, and certain state and foreign, deferred tax assets before they expire and as such a valuation allowance has been recorded.  The valuation allowance represents the amount of tax benefit related to U.S. federal, state and foreign net operating losses, credits and other deferred tax assets.
	The Company has net operating loss carry forwards of $106,637,  $96,260 and $22,381 for U.S. federal, state and foreign tax jurisdictions, respectively.  The U.S. federal net operating losses, if unused, begin to expire in December 31, 2025, the state net operating losses expire at various times and the foreign net operating losses expire at various times or have indefinite expiration dates.  The Company has general business and foreign tax credit carry forwards of $12,271,  $2,005 and $1,908 for U.S. federal, state and foreign jurisdictions respectively.  The U.S. federal general business credits, if unused, begin to expire in December 31, 2021, and the state and foreign tax credits expire at various times. The Company is required to provide a deferred tax liability corresponding to the difference between the financial reporting basis (which was remeasured to fair value upon the acquisition of an additional 24% of PST in 2011) and the tax basis in the previously held 50% ownership interest in PST (the “outside” basis difference). This outside basis difference will generally remain fixed until (1) dividends from the subsidiary exceed the parent’s share of earnings subsequent to the date it became a subsidiary or (2) there is a transaction that affects the Company’s ownership of PST.
	During the fourth quarter of 2010 we undertook a secondary offering.  As a result of the secondary offering a substantial change in our ownership occurred and we experienced an ownership change pursuant to Section 382 of the Code. There was no impact to current or deferred income taxes resulting from the ownership change.
	The following is a reconciliation of the Company’s total gross unrecognized tax benefits:
			2013		2012		2011
	Balance as of January 1	$	3,416	$	3,452	$	3,101
	Tax positions related to the current year:
	Additions		217		93		381
	Tax positions related to the prior years:
	Additions		216		-		28
	Reductions		-71		-58		-
Expirations of statutes of limitation		-		-71		-58
Balance as of December 31	$	3,778	$	3,416	$	3,452
At December 31, 2013 the Company has classified $639 as a noncurrent liability and $3,329 as a reduction to non-current deferred income tax assets. The amount of unrecognized tax benefits is not expected to change significantly during the next 12 months.  Management is currently unaware of issues under review that could result in a significant change or a material deviation in this estimate.
If the Company’s tax positions at December 31, 2013 are sustained by the taxing authorities in favor of the Company, approximately $3,547 would affect the Company’s effective tax rate.
Consistent with historical financial reporting, the Company has elected to classify interest expense and, if applicable, penalties which could be assessed related to unrecognized tax benefits as a component of income tax expense.  For the years ended December 31, 2013, 2012 and 2011, the Company recognized approximately $(82),  $64 and $67 of gross interest and penalties, respectively.  The Company has accrued approximately $624 and $706 for the payment of interest and penalties at December 31, 2013 and 2012, respectively.
The Company conducts business globally and, as a result, files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.  In the normal course of business the Company is subject to examination by taxing authorities throughout the world. The following table summarizes the open tax years for each important jurisdiction:
Jurisdiction	Open Tax Years

	7. Share-Based Compensation Plans
	In May 2002, the Company adopted the Director Share Option Plan (“Director Option Plan”).  The Company reserved 500,000 Common Shares for issuance under the Director Option Plan.  Under the Director Option Plan, the Company granted cumulative options to purchase 86,000 Common Shares to directors of the Company with exercise prices equal to the fair market value of the Company’s Common Shares on the date of grant.  The options granted cliff-vested one year after the date of grant and have a contractual life of 10 years.  The Director Option Plan expired in May 2012.
	In April 2006, the Company’s shareholders approved the Amended and Restated Long-Term Incentive Plan (the "2006 Plan") and reserved 3,000,000  Common Shares of which the maximum number of Common Shares which may be issued subject to incentive stock options is 500,000.  In May 2013, shareholders approved an amendment to the 2006 Plan to increase the number of shares from 3,000,000 to 4,500,000.  Under the 2006 Plan, as of December 31, 2013, the Company has issued 3,319,200 restricted Common Shares, of which 2,145,300 are time-based with cliff vesting using the straight-line method and 1,173,900 are performance-based.    Restricted Common Shares awarded under the Incentive Plan entitle the shareholder to all the rights of Common Share ownership except that the shares may not be sold, transferred, pledged, exchanged, or otherwise disposed of during the vesting period.
	In 2008, pursuant to the 2006 Plan, the Company granted time-based restricted Common Share and performance-based restricted Common Share awards.  The time-based restricted Common Share awards cliff vest three years after the grant date.  The performance-based restricted Common Share awards vest and are no longer subject to forfeiture upon the recipient remaining an employee of the Company for three years from date of grant and upon achieving certain net income per share targets established by the Company.
	In 2009, pursuant to the 2006 Plan, the Company granted time-based restricted Common Share awards.  These restricted Common Share awards cliff vest three years after the grant date.
	In 2010 and 2013, pursuant to the 2006 Plan, the Company granted time-based restricted Common Share and market-based restricted Common Share awards.  The time-based restricted Common Share awards cliff vest three years after the date of grant.  The performance-based restricted Common Share awards vest and are no longer subject to forfeiture upon the recipient remaining an employee of the Company for three years from the date of grant and upon the Company attaining certain targets of performance measured against a peer group’s performance in terms of total return to shareholders.
	In 2011 and 2012, pursuant to the 2006 Plan, the Company granted time-based, market-based and performance-based restricted Common Share awards.  The time-based restricted Common Share awards cliff vest three years after the date of grant.  The performance-based restricted Common Share awards vest and are no longer subject to forfeiture upon the recipient remaining an employee of the Company for three years from the date of grant and, for one half of the annual awards, upon the Company attaining certain targets of performance measured against a peer group’s performance in terms of total shareholder return and, for the remaining half of the annual awards, upon achieving certain annual net income per share targets established by the Company during the performance period of the award.
	In April 2005, the Company adopted the Directors’ Restricted Shares Plan (“Director Share Plan”) and reserved 500,000 Common Shares for issuance under the Director Share Plan.  In May 2013, shareholders approved an amendment to the Director Share Plan to increase the number of shares for issuance from 500,000 to 700,000.  Under the Director Share Plan, the Company has cumulatively issued 435,534 restricted Common Shares.  Shares issued under the Director Share Plan during 2010, 2011, 2012 and 2013 cliff vest one year after the date of grant.
	Options
	A summary of option activity under the plans noted above as of December 31, 2013, and changes during the year ended are presented below:
					Weighted-
				Weighted-	average
				average	remaining
		Share		exercise	contractual
		options		price	term
	Outstanding as of December 31, 2012	59,000	$	12.20
	Expired	-39,000	$	10.39
	Exercised	-	$	-
	Outstanding and exercisable as of December 31, 2013	20,000	$	15.73	0.36
	There were no options granted during the years ended December 31, 2013, 2012 and 2011, and all outstanding options have vested.
	The intrinsic value of options outstanding and exercisable is the difference between the fair market value of the Company’s Common Shares on the applicable date (“Measurement Value”) and the exercise price of those options that had an exercise price that was less than the Measurement Value. The intrinsic value of options exercised is the difference between the fair market value of the Company’s Common Shares on the date of exercise and the exercise price.  There were no options exercised during the years ended December 31, 2013 and 2012.  The total intrinsic value of options exercised during the year ended December 31, 2011 was $117.
	As of December 31, 2013, 2012, and 2011, the aggregate intrinsic value of both outstanding and exercisable options was $0,  $0, and $5, respectively.
	Restricted Shares
	The fair value of the non-vested time-based restricted Common Share awards was calculated using the market value of the shares on the date of issuance.  The weighted-average grant-date fair value of time-based restricted Common Shares granted during the years ended December 31, 2013, 2012 and 2011 was $6.13,  $9.95 and $15.79, respectively.
	The fair value of the non-vested performance-based restricted Common Share awards with a performance condition requiring the Company to obtain certain earnings per share targets was estimated using the market value of the shares on the date of grant.  The fair value of non-vested performance-based restricted Common Share awards with a market condition requiring the Company to obtain a total shareholder return target relative to a group of peer companies was estimated using a Monte Carlo valuation model taking into consideration the probability of achievement using multiple simulations.
	A summary of the status of the Company’s non-vested restricted Common Shares as of December 31, 2013 and the changes during the year then ended, are presented below:
		Time-based awards			Performance-based awards
				Weighted-			Weighted-
		Common		average grant-	Common		average grant-

	Non-vested as of December 31, 2013	1,126,870	$	8.83	663,750	$	11.45
	As of December 31, 2013, total unrecognized compensation cost related to non-vested time-based restricted Common Share awards granted was $3,330.  That cost is expected to be recognized over a weighted-average period of 1.93 years.  For the years ended December 31, 2013, 2012 and 2011, the total fair value of time-based restricted Common Share awards vested was $2,177,  $4,413 and $3,743, respectively.
	As of December 31, 2013, total unrecognized compensation cost related to non-vested performance-based restricted Common Share awards granted was $1,873.  That cost is expected to be recognized over a weighted-average period of 1.25 years dependent upon the achievement of performance conditions.  As noted above, the Company has issued and outstanding performance-based restricted Common Share awards that use different performance targets.  The awards that use earnings per share as the performance target will not be expensed until it is probable that the Company will meet the underlying performance condition.
	Cash received from option exercises under all share-based payment arrangements for the years ended December 31, 2013, 2012 and 2011 was $0,  $0 and $168, respectively.  There was no actual tax benefit realized for the tax deductions from the vesting of restricted Common Shares and option exercises of the share-based payment arrangements for the years ended December 31, 2013, 2012 and 2011.

Employee Benefit Plans	'
	8. Employee Benefit Plans
	The Company has certain defined contribution profit sharing and 401(k) plans covering substantially all of its employees in the United States and United Kingdom. Company contributions are generally discretionary.  The Company’s policy is to fund all benefit costs accrued. For the years ended December 31, 2013, 2012 and 2011, expenses related to these plans amounted to $1,469,  $1,527 and $1,801, respectively.
	The Company provides matching contributions to the Company’s 401(k) plan covering substantially all of its employees in the United States.
	Long-Term Cash Incentive Plans
	In March 2009, the Company adopted the Stoneridge, Inc. Long-Term Cash Incentive Plan (“LTCIP”) and granted awards to certain officers and key employees.  Awards under the LTCIP provided recipients with the right to receive cash three years from the date of grant depending on the Company’s actual earnings per share performance for the defined performance period. If the participant voluntarily terminated employment or was discharged for cause, as defined in the LTCIP, the award would be forfeited.  In May 2009, the LTCIP was approved by the Company’s shareholders.  At December 31, 2011, the Company had a liability recorded of $2,173, which was paid in March 2012 based on achievement of the performance goal.  As such, no liability remains for this award at December 31, 2012 or 2013.
	For 2010, the awards under the LTCIP provided recipients with the right to receive an amount of cash equal to the fair market value of a specified number of Common Shares, without par value, of the Company (“Phantom Shares”) three years from the date of grant depending on the Company’s actual earnings per share performance for each fiscal year of 2011, 2012 and 2013 within the performance period.  The Company recorded an accrual based on the fair market value of the Phantom Shares for an award to be paid in the period earned based on anticipated achievement of the performance goals.  If the participant voluntarily terminates employment or is discharged for cause, as defined in the LTCIP, the award will be forfeited.    At December 31, 2012, the Company recorded a liability of $606 for the awards granted under the LTCIP which was included on the consolidated balance sheet as component of accrued expenses and other current liabilities. In February 2013, the 2010 awards were paid based on achievement of the performance goal.  As such, no liability remains for this award at December 31, 2013.
	For 2013, the Company granted Phantom Share awards that vest three years from the date of grant depending on the Company’s actual earnings per share performance for each fiscal year of 2013, 2014 and 2015 within the performance period.  As of December 31, 2013, the Company has not recorded a liability as the 2013 performance goal was not achieved.  There were no awards granted under the LTCIP during the year ended December 31, 2012 or 2011.

Financial Instruments and Fair Value Measurements	'
	9. Financial Instruments and Fair Value Measurements
	Financial Instruments
	A financial instrument is cash or a contract that imposes an obligation to deliver, or conveys a right to receive cash or another financial instrument.  The carrying values of cash and cash equivalents, accounts receivable and accounts payable are considered to be representative of fair value because of the short maturity of these instruments.  The estimated fair value of the Company’s senior secured notes with a face value of $175,000 (fixed rate debt) at December 31, 2013 and 2012 was $190,103 and $188,895, respectively, and was determined using market quotes classified as Level 2 input within the fair value hierarchy.
	Derivative Instruments and Hedging Activities
	On December 31, 2013, the Company had open foreign currency forward contracts, fixed price commodity contracts and an interest rate swap.   These contracts are used solely for hedging and not for speculative purposes.  Management believes that its use of these instruments to reduce risk is in the Company’s best interest.  The counterparties to these financial instruments are financial institutions with investment grade credit ratings.
	Foreign Currency Exchange Rate Risk
	The Company conducts business internationally and therefore is exposed to foreign currency exchange rate risk.  The Company uses derivative financial instruments as cash flow and fair value hedges to mitigate its exposure to fluctuations in foreign currency exchange rates by reducing the effect of such fluctuations on foreign currency denominated intercompany transactions and other foreign currency exposures. The currencies hedged by the Company during 2013 include the euro and Mexican peso.
	In certain instances, the foreign currency forward contracts do not qualify for hedge accounting and are marked to market, with gains and losses recognized in the Company’s consolidated statements of operations as a component of  other expense, net.
	The Company’s foreign currency forward contracts offset some of the gains and losses on the underlying foreign currency denominated transactions as follows:
	Euro-denominated and Swedish krona-denominated Foreign Currency Forward Contracts
	At December 31, 2013 and 2012, the Company held a foreign currency forward contract with an underlying notional amount of $13,335 and $12,643, respectively, to reduce the exposure related to the Company’s euro-denominated intercompany loans. This contract expires in March 2014.  During 2012, the Company also held a foreign currency forward contract to reduce the exposure related to the Company’s Swedish krona-denominated intercompany loans.  This contract expired on November 30, 2012.  The euro-denominated and Swedish krona-denominated foreign currency forward contracts have not been designated as hedging instruments.   For the years ended December 31, 2013 and 2012, the Company recognized a loss of $638 and $492, respectively, in the consolidated statements of operations as a component of other expense, net related to the euro- and Swedish krona-denominated contracts.  For the year ended December 31, 2011, the Company recognized a $225 gain related to foreign currency forward contracts.
	Mexican peso-denominated Foreign Currency Forward Contracts – Cash Flow Hedge
	The Company holds Mexican peso-denominated foreign currency contracts with notional amounts at December 31, 2013 totaling $45,000 which expire ratably on a monthly basis from January 2014 through December 2014.  The Company held Mexican peso-denominated foreign currency contracts with notional amounts at December 31, 2012 of 36,500 which expired ratably on a monthly basis from January 2013 through December 2013.
	These contracts were executed to hedge forecasted transactions and are accounted for as cash flow hedges.   As such, the effective portion of the unrealized gain or loss is deferred and reported in the Company’s consolidated balance sheets as a component of accumulated other comprehensive loss.  The cash flow hedges are highly effective and the Company expects them to remain highly effective in future periods.  The effectiveness of the transactions has been and will be measured on an ongoing basis using regression analysis and forecasted future Mexican peso purchases.
	Commodity Price Risk - Cash Flow Hedge
	To mitigate the risk of future price volatility and, consequently, fluctuations in gross margins, the Company entered into fixed price commodity contracts with a financial institution to fix the cost of a portion of the Company’s copper purchases as copper is a significant raw material.
	The Company has fixed price commodity contracts at December 31, 2013 with an aggregate notional amount of 1,582 pounds, which expire on a monthly basis over the period from January through December 2014, compared to an aggregate notional amount of 2,436 pounds at December 31, 2012.
	All of these contracts represent a portion of the Company’s forecasted copper purchases.  These contracts were executed to hedge a portion of forecasted transactions and the contracts are accounted for as cash flow hedges.  The unrealized gain or loss for the effective portion of the hedges is deferred and reported in the Company’s consolidated balance sheets as a component of  accumulated other comprehensive loss while the ineffective portion, if any, is reported in the consolidated statements of operations. The effectiveness of the transactions is measured on an ongoing basis using regression analysis and forecasted future copper purchases.  Based upon the results of the regression analysis, the Company has concluded that these cash flow hedges are highly effective.
	Interest Rate Risk - Fair Value Hedge
	The Company has a fixed-to-floating interest rate swap agreement (the “Swap”) with a notional amount of $45,000 to hedge its exposure to fair value fluctuations on a portion of its senior secured notes.  The Swap was designated as a fair value hedge of the fixed interest rate obligation under the Company’s $175,000 9.5% senior secured notes due October 15, 2017.  The critical terms of the Swap are aligned with the terms of the senior secured notes, including maturity of October 15, 2017, resulting in no hedge ineffectiveness.  The unrealized gain or loss for the effective portion of the hedge is deferred and reported in the Company’s consolidated balance sheets as an asset or liability, as applicable, with the offset to the carrying value of the senior secured notes.
	Under the Swap, the Company pays a variable interest rate equal to the six-month London Interbank Offered Rate (“LIBOR”) plus 7.2% and it receives a fixed interest rate of 9.5%.  The Swap requires semi-annual settlements on April 15 and October 15.  The difference between amounts to be received and paid under the Swap is recognized as a component of interest expense, net on the consolidated statements of operations.
	The Swap reduced interest expense by $810,  $736 and $473 for the years ended December 31, 2013, 2012 and 2011, respectively.
	The notional amounts and fair values of derivative instruments in the consolidated balance sheets were as follows:
			Notional amounts			(A)	Prepaid expenses and other current assets / other long-term assets					Accrued expenses and other current liabilities

	The net deferred losses of $111 on the cash flow hedge derivatives will be reclassified from other comprehensive income (loss) to the consolidated statements of operations in 2014.  The Company has measured the ineffectiveness of the forward currency and commodity contracts and any amounts recognized in the consolidated financial statements were immaterial for the years ended December 31, 2013, 2012 and 2011.
	Fair Value Measurements
	The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.  The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value.
											December 31,		December 31,
											2013		2012
							Fair value estimated using
					Fair value		Level 1 inputs (A)		Level 2 inputs (B)		Level 3 inputs (C)		Fair value
	Financial assets carried at fair value:
	Interest rate swap contract				$                793		$                    -		$                793		$                    -		$           2,212
	Forward currency contracts				-		-		-		-		1,800

	Total financial liabilities carried at fair value				$                281		$                    -		$                281		$                    -		$              191
(A)	Fair values estimated using Level 1 inputs, which consist of quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.  The Company did not have any fair value estimates using Level 1 inputs at  December 31, 2013 or 2012.
(B)	Fair values estimated using Level 2 inputs, other than quoted prices, that are observable for the asset or liability, either directly or indirectly and include among other things, quoted prices for similar assets or liabilities in markets that are active or inactive as well as inputs other than quoted prices that are observable.  For forward currency, fixed price commodity and interest rate swap contracts, inputs include foreign currency exchange rates, commodity indexes and the six-month forward LIBOR.
(C)	Fair values estimated using Level 3 inputs consist of significant unobservable inputs.  The Company did not have any fair value estimates using Level 3 inputs at December 31, 2013 or 2012.
For the year ended December 31, 2011, the Company recorded a fair value adjustment of $4,945 related to the BCS goodwill.  The Company utilized Level 3 inputs to estimate the fair value adjustment for nonfinancial assets.  For additional information, see the discussion of Goodwill and Other Intangible Assets in Note 2.  No adjustments to fair value were required for nonfinancial assets for the years ended December 31, 2013 or 2012.

	10. Commitments and Contingencies
	In the ordinary course of business, the Company is subject to various claims and legal proceedings, workers’ compensation and product liability disputes.  The Company is of the opinion that the ultimate resolution of these matters will not have a material adverse affect on the results of operations, cash flows or the financial position of the Company.
	As a result of environmental studies performed at the Company’s former facility located in Sarasota, Florida, the Company became aware of soil and groundwater contamination at the Company site.  The Company engaged an environmental engineering consultant to assess the level of contamination and to develop a remediation and monitoring plan for the site.  Soil remediation at the site was completed during the year ended December 31, 2010.  Ground water remediation will begin  in the first quarter of 2014,  in accordance with a remedial action plan approved by the Florida Department of Environmental Protection.  During the years ended December 31, 2013 and 2012, environmental remediation costs incurred were immaterial.  At December 31, 2013 and 2012, the Company had accrued an undiscounted liability of $944 and $1,340, respectively, related to future remediation. The decrease in the accrual is related to changes in assumptions used in the remedial action plan.  At December 31, 2013 and 2012, $683 and $733, respectively, were recorded as a component of accrued expenses and other current liabilities on the consolidated balance sheets while the remaining amounts were recorded as a component of other long-term liabilities.  A majority of the costs associated with the recorded liability will be incurred at the start of the groundwater remediation, with the balance relating to monitoring costs to be incurred over multiple years.  The recorded liability is based on assumptions in the remedial action plan.   In December 2011, the Company sold the Sarasota facility and related property.  However, the liability to remediate the site contamination remains the responsibility of the Company.  Due to the ongoing site remediation, the closing terms of the sale agreement included a requirement for the Company to maintain a $2,000 letter of credit for the benefit of the buyer.
	On May 24, 2013, the State Revenue Services of São Paulo issued a tax deficiency notice against PST, our 74% owned consolidated subsidiary, claiming that the vehicle tracking and monitoring services it provides should be classified as communication services, and therefore subject to the State Value Added Tax – ICMS. The State Revenue Services assessment imposed the 25.0% ICMS tax on all revenues of PST related to the vehicle tracking and monitoring services during the period from January 2009 through December 2010. The Brazilian real (“R$”) and (U.S. dollar equivalent “$”) of the aggregate tax assessment is approximately R$92,500 ($39,500) which is comprised of Value Added Tax – ICMS of R$13,200 ($5,600), interest of R$11,400 ($4,900) and penalties of R$67,900 ($29,000).
	The Company’s vehicle tracking and monitoring services are non-communication services, as defined under Brazilian tax law, subject to the municipal ISS tax, not communication services subject to state ICMS tax as claimed by the State Revenue Services of São Paulo. PST has, and will continue to collect the municipal ISS tax on the vehicle tracking and monitoring services in compliance with Brazilian tax law and will defend its tax position. PST has received a legal opinion that the merits of the case are favorable to PST, determining among other things that the imposition on the subsidiary of the State ICMS by the State Revenue Services of São Paulo is not in accordance with the Brazilian tax code.   Management believes, based on the legal opinion of PST’s Brazilian legal counsel and the results of the Brazil Administrative Court's ruling in favor of another vehicle tracking and monitoring company related to the tax deficiency notice it received, the likelihood of loss is not probable although it may take years to resolve.   As a result of the above, as of December 31, 2013, no provision has been made with respect to this tax assessment.   An unfavorable judgment on this issue for the years assessed and for subsequent years could result in significant costs to PST and adversely affect its results of operations.
	In addition, PST has civil, labor and tributary contingencies for which the likelihood of loss is deemed to be reasonably possible, but not probable, by its legal advisors.  As a result, no provision has been made with respect to these contingencies, which amount to $11,469 and $11,925 at December, 2013 and 2012, respectively.  An unfavorable outcome on this issue could result in significant cost to PST and adversely affect its results of operations.

	On October 29, 2007, the Company announced restructuring initiatives to improve manufacturing efficiency and cost position by ceasing manufacturing operations at its Sarasota, Florida (Control Devices reportable segment) and Mitcheldean, United Kingdom (Electronics reportable segment) locations.  During 2008 and 2009, in response to the depressed conditions in the North American and European commercial and automotive vehicle markets, the Company continued and expanded the restructuring initiatives in the Control Devices and Electronics reportable segments. While the initiatives were completed in 2009 in regards to the Control Devices reportable segment, in 2010 the Company continued restructuring initiatives within the Electronics reportable segment and recorded amounts related to its cancelled property lease in Mitcheldean, United Kingdom. During the third quarter of 2012, the Company finalized a settlement agreement to modify the terms of and the obligation associated with the property consistent with previous estimates.
	As a result of the restructuring plan approved on October 29, 2007, the manufacturing facility located in Sarasota, Florida was closed in 2008.  During the year ended December 31, 2011, the Company sold the facility and recognized a gain of $95 as a component of selling, general and administrative expense.
	In connection with the Electronics segment restructuring initiative, the Company recorded lease related restructuring charges during the year ended December 31, 2013 and 2012 of $469 and $256, respectively, as part of selling, general and administrative expense.  At December 31, 2013 and 2012, the only remaining restructuring related accrual relates to the cancelled property lease in Mitcheldean, United Kingdom, for which the Company has accrued $780 and $765, respectively, on the consolidated balance sheets of which $427 and $419, respectively, is a component of other long-term liabilities.
	The expenses related to the restructuring activities that belong to the Electronics reportable segment include the following:
			Contract
			termination costs
	Accrued balance at January 1, 2011	$	1,117
	2011 charge to expense		951

	Foreign currency translation effect		24
	Cash payments		-478
	Accrued balance at December 31, 2013	$	780
	There were no significant restructuring expenses related to the Wiring or Control Devices reportable segments during the years ended December 31, 2013, 2012 or 2011.
	In response to a change in customer demand, the PST segment incurred and paid business realignment charges of $1,646 for the year ended December 31, 2012, of which $729 was recorded in cost of goods sold with the remainder recorded in selling, general and administrative expenses.  The charges consist primarily of severance costs related to workforce reductions.  There were no restructuring expenses related to the PST segment during the year ended December 31, 2013.
	Contract termination costs represent costs associated with long-term lease obligations that were cancelled as part of the restructuring initiatives.

	12. Segment Reporting
	Operating segments are defined as components of an enterprise that are evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance.  The Company’s chief operating decision maker is the chief executive officer.
	The Company has four reportable segments: Control Devices, Electronics, Wiring and PST which also represents its operating segments.  The Control Devices reportable segment produces sensors, switches, valves and actuators. The Electronics reportable segment produces electronic instrument clusters, electronic control units and driver information systems.  The Wiring reportable segment produces electrical power and signal distribution systems, primarily wiring harnesses and connectors and instrument panel assemblies.  The PST reportable segment specializes in the design, manufacture and sale of electronic vehicle security alarms, convenience accessories, vehicle tracking devices and monitoring services and in-vehicle audio and video devices.
	The accounting policies of the Company’s reportable segments are the same as those described in Note 2.  The Company’s management evaluates the performance of its reportable segments based primarily on revenues from external customers, capital expenditures and income before income taxes.  Inter-segment sales are accounted for on terms similar to those to third parties and are eliminated upon consolidation.
	A summary of financial information by reportable segment is as follows:

Summary of Significant Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Stoneridge, Inc. and its wholly-owned and majority-owned subsidiaries (collectively, the “Company”).  Intercompany transactions and balances have been eliminated in consolidation.  The Company analyzes its ownership interests in accordance with Accounting Standards Codification “ASC” Topic 810 to determine whether they are VIE’s and, if so, whether the Company is the primary beneficiary.  The Company’s investment in Minda Stoneridge Instruments Ltd. (“Minda”) at December 31, 2013, 2012 and 2011 was determined under the provisions of ASC Topic 810 to be an unconsolidated entity and was accounted for under the equity method of accounting based on our 49% noncontrolling interest.
	On December 31, 2011, the Company completed the acquisition of an additional 24% controlling interest in PST Eletrônica Ltda. (“PST”).     As a result, the Company owns 74% of the outstanding equity of PST.
	PST’s results for the years ended December 31,  2013 and 2012 were consolidated such that 100% of PST’s operations were included in each line from net sales through net income in the Company’s consolidated statements of operations with the 26% noncontrolling interest reduced (increased) in the net income (loss) attributable to noncontrolling interest line.
	PST’s results for the year ended December 31, 2011 were accounted for as an unconsolidated joint venture under the equity method of accounting such that our 50% portion of PST’s after-tax earnings were included within equity in earnings of investees in the consolidated statements of operations as a controlling interest in PST was not acquired until the close of business on December 31, 2011.
Accounting Estimates	'
	Accounting Estimates
	The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including certain self-insured risks and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Because actual results could differ from those estimates, the Company revises its estimates and assumptions as new information becomes available.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company’s cash and cash equivalents are actively traded money market funds with short-term investments in marketable securities, primarily U.S. government securities. Cash and cash equivalents are stated at cost, which approximates fair value, due to the highly liquid nature and short-term duration of the underlying securities.
Accounts Receivable and Concentration Of Credit Risk	'
	Accounts Receivable and Concentration of Credit Risk
	Revenues are principally generated from the commercial, automotive, agricultural, motorcycle and off-highway vehicle markets.  The Company’s largest customers were Deere & Company (“Deere”) and Navistar International Corporation (“Navistar”), primarily related to the Wiring reportable segment, and accounted for the following percentages of consolidated net sales for the years ended December 31, 2013, 2012 and 2011:
			2013			2012			2011
	Deere		14	%		13	%		15	%
	Navistar		13	%		18	%		24	%
	Accounts receivable are recorded at the invoice price net of an estimate of allowance for doubtful accounts and other reserves.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	The Company evaluates the collectability of accounts receivable based on a combination of factors.  In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations, a specific allowance for doubtful accounts is recorded against amounts due to reduce the net recognized receivable to the amount the Company reasonably believes will be collected.  Additionally, the Company reviews historical trends for collectability in determining an estimate for its allowance for doubtful accounts.  If economic circumstances change substantially, estimates of the recoverability of amounts due to the Company could be reduced by a material amount.  The Company does not have collateral requirements with its customers.
Inventories	'
	Inventories
	Inventories are valued at the lower of cost (using either the first-in, first-out (“FIFO”) or average cost methods) or market.  The Company evaluates and adjusts as necessary its excess and obsolescence reserve on a quarterly basis.  Excess inventories are quantities of items that exceed anticipated sales or usage for a reasonable period.  The Company has guidelines for calculating provisions for excess inventories based on the number of months of inventories on hand compared to anticipated sales or usage.  Management uses its judgment to forecast sales or usage and to determine what constitutes a reasonable period.  Inventory cost includes material, labor and overhead. Inventories consist of the following:
	As of December 31			2013		2012
	Raw materials		$	71,631	$	64,340
	Work-in-progress			16,168		13,621
	Finished goods			26,259		18,071
	Total inventories, net		$	114,058	$	96,032
	Inventory valued using the FIFO method was $67,750 and $57,004 at December 31, 2013 and 2012, respectively.  Inventory valued using the average cost method was $46,308 and $39,028 at December 31, 2013 and 2012, respectively.
Pre-Production Costs Related to Long-Term Supply Arrangements	'
	Pre-production Costs Related to Long-term Supply Arrangements
	Engineering, research and development and other design and development costs for products sold on long-term supply arrangements are expensed as incurred unless the Company has a contractual guarantee for reimbursement from the customer.  Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company either has title to the assets or has the noncancelable right to use the assets during the term of the supply arrangement are capitalized in property, plant and equipment and amortized to cost of sales over the shorter of the term of the arrangement or over the estimated useful lives of the assets, typically three to five years.  Costs for molds, dies and other tools used to make products sold on long-term supply arrangements for which the Company has a contractual guarantee to a lump sum reimbursement from the customer are capitalized as a component of prepaid expenses and other current assets within the consolidated balance sheets.  The amounts recorded related to these pre-production costs as of December 31, 2013 and 2012 were $12,944 and $8,631, respectively.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment are recorded at cost and consist of the following:
	As of December 31			2013		2012
	Land and land improvements		$	4,861	$	5,117
	Buildings and improvements			43,630		45,940
	Machinery and equipment			208,243		196,003
	Office furniture and fixtures			8,351		8,856
	Tooling			70,050		71,045
	Information technology			33,759		33,009
	Vehicles			426		1,456
	Leasehold improvements			3,447		3,560
	Construction in progress			14,336		17,656
	Total property, plant, and equipment			387,103		382,642
	Less: accumulated depreciation			-276,231		-263,495
	Property, plant and equipment, net		$	110,872	$	119,147
	Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Depreciation expense for the years ended December 31, 2013, 2012 and 2011 was $28,989,  $28,519 and $18,847, respectively. Depreciable lives within each property classification are as follows:
	Buildings and improvements			10-40 years
	Machinery and equipment			3-10 years
	Office furniture and fixtures			3-10 years
	Tooling			2-5 years
	Information technology			3-5 years
	Vehicles			3-5 years
	Leasehold improvements	shorter of lease term or 3-10 years
	Maintenance and repair expenditures that are not considered improvements and do not extend the useful life of the property, plant and equipment are charged to expense as incurred.  Expenditures for improvements and major renewals are capitalized.  When assets are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts, and any gain or loss on the disposition is recorded in the consolidated statements of operations as a component of selling, general and administrative expenses.
Impairment of Long-Lived or Finite-Lived Assets	'
	Impairment of Long-Lived or Finite-Lived Assets
	The Company reviews the carrying value of its long-lived assets and finite-lived intangible assets for impairment when events or circumstances indicate that their carrying value may not be recoverable.  Factors the Company considers important that could trigger testing of the related asset groups for an impairment include current period operating or cash flow losses combined with a history of operating or cash flow losses, a projection or forecast that demonstrates continuing losses, significant adverse changes in the business climate within a particular business or current expectations that a long-lived asset will be sold or otherwise disposed of significantly before the end of its estimated useful life.  To test for impairment, the estimated undiscounted cash flows expected to be generated from the use and disposal of the asset or asset group is compared to its carrying value.  An asset group is established by identifying the lowest level of cash flows generated by the group of assets that are largely independent of cash flows of other assets.  If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the group of assets for which we can identify projected cash flows.  If these undiscounted cash flows are less than their respective carrying values, an impairment charge would be recognized to the extent that the carrying values exceed estimated fair values.  Although third-party estimates of fair value are utilized when available, the estimation of undiscounted cash flows and fair value requires us to make assumptions regarding future operating results.  The results of the impairment testing are dependent on these estimates which require judgment.  The occurrence of certain events, including changes in economic and competitive conditions, could impact cash flows eventually realized and management’s ability to accurately assess whether an asset is impaired.
	During the year ended December 31, 2011, the Company recorded an impairment charge of $807 in its Wiring reportable segment related to certain capitalized software costs that were determined to no longer represent a future realizable benefit.  This charge is recorded in the consolidated statements of operations as a component of selling, general and administrative expenses.  No material impairment charges were recorded in 2013 or 2012 for long-lived or finite-lived intangible assets.
Acquisitions	'
	Acquisitions
	PST Eletrônica Ltda.
	On December 31, 2011, the Company acquired a controlling interest in PST, by increasing its interest from 50% to 74%.  Prior to the acquisition of the additional interest, the PST joint venture was accounted for under the equity method of accounting.  On the date of acquisition of controlling interest, PST became a consolidated subsidiary and a new reportable segment of the Company.   PST’s results of operations were consolidated and included in the Company’s consolidated statements of operations, comprehensive income and cash flows for the year ended December 31, 2013 and 2012.  For the year ended December 31, 2011, PST’s results of operations and cash flows were included in the Company’s consolidated statements of operations and cash flows as equity in earnings of investees.  PST’s financial position is included in the consolidated balance sheets at December 31, 2013 and 2012.
	As a result of obtaining a controlling interest in PST, the Company’s previously held 50% equity interest in PST of $38,746 was remeasured to an acquisition date fair value of $104,118.  The Company recognized a one-time non-cash pre-tax gain on previously held equity interest of $65,372 as a result of this remeasurment in the fourth quarter of 2011.
	The acquisition date fair value of the total consideration transferred consisted of the following:
	Cash	$	29,669
	Common Shares (1,940,413 shares)		15,310
	Fair value of consideration transferred		44,979
	Fair value of the Company's previously held equity interest		104,118
	Fair value of noncontrolling interest		48,727
	Total fair value of PST	$	197,824
	Of the $44,979 consideration transferred for the additional 24% interest, $29,976 ($19,779 of cash and $10,197 of the fair value of 1,293,609 Company Common Shares) was transferred on January 5, 2012, in accordance with the terms of the purchase agreement.
	The fair value of the Common Shares transferred was based on the closing market price of the Company’s Common Shares on the acquisition date, less a discount for a lack of short-term marketability as the Common Shares transferred were issued through a private placement.
	Goodwill of $67,118 was calculated as the excess of the fair value of consideration transferred over the fair market value of the identifiable assets and liabilities and represents the future economic benefits arising from other assets acquired that could not be separately recognized.  Goodwill is reported in the Company’s PST segment and is not deductible for income tax purposes.
	The Company identified $97,398 of intangible assets that include; $47,126 assigned to customer lists with a 15 year useful life; $31,400 assigned to trademarks with a 20 year useful life; and $18,872 assigned to technology with a 17 year weighted-average useful life.  The fair value of the identifiable intangible assets was determined using an income approach.
	The following unaudited pro forma information reflects the Company’s consolidated results of operations as if the acquisition had occurred on January 1, 2011. The unaudited pro forma information is not necessarily indicative of the results of operations that the Company would have reported had the transaction actually occurred at the beginning this period, nor is it necessarily indicative of future results.
	Years ended December 31		2011
	Net sales		$          999,553
	Net income attributable to Stoneridge, Inc.		$            10,608
	The unaudited pro forma financial information presented in the table above has been adjusted to give effect to adjustments that are directly related to the business combination and factually supportable. These tax affected adjustments include, but are not limited to depreciation and amortization related to fair value adjustments to property, plant, and equipment, intangible assets and inventory.
	Bolton Conductive Systems, LLC
	On October 13, 2009, the Company acquired a 51% controlling interest in Bolton Conductive Systems, LLC (“BCS”) for a purchase price of $5,967, net of cash acquired.  BCS designs and manufactures a wide variety of electrical solutions for the military, automotive, marine and specialty vehicle markets. The Company purchased the remaining 49% noncontrolling interest in BCS in February 2013 for a nominal amount, which was treated as an equity transaction.
	During the period from February 2013 through December 2013, 100% of BCS results of operations were included in the Company’s consolidated statements of operations.  During the years ended December 31, 2012 and 2011, 49% of BCS’s results were included within loss attributable to noncontrolling interest within the consolidated statements of operations.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	The total purchase price associated with acquisitions is allocated to the acquisition date fair values of identifiable assets acquired and liabilities assumed, with the excess purchase price assigned to goodwill.
	In 2011, the Company recorded goodwill of $67,118 related to the acquisition of PST (see Acquisitions above).  In 2009, the Company recorded goodwill of $9,118 within the Wiring segment related to the BCS acquisition. The goodwill related to these acquisitions is not deductible for income tax purposes.  The remainder of the December 31, 2013 and 2012 goodwill balance relates to the 2008 acquisition of Magnum Trade AB, which is included within the Electronics segment.
	Goodwill as of December 31, 2013 and 2012, and changes in the carrying amount of goodwill by segment were as follows:
							Control
			Electronics		Wiring		Devices		PST		Total
	Balance at January 1, 2012	$	564	$	4,173	$	-	$	67,118	$	71,855
	Currency translation		34		-		-		-5,508		-5,474
	Balance at December 31, 2012		598		4,173		-		61,610		66,381
	Currency translation		6		-		-		-7,866		-7,860
	Balance at December 31, 2013	$	604	$	4,173	$	-	$	53,744	$	58,521
	Goodwill is subject to an annual assessment for impairment (or more frequently if impairment indicators arise) by applying a fair value-based test.
	The Company performed its annual impairment test of goodwill as of the beginning of the fourth quarter.  The Company utilized an income approach (discounted cash flow method) valuation technique in determining the fair value of the Company’s applicable reporting units in the annual impairment test of goodwill. The discounted cash flow method utilizes a market-derived rate of return to discount anticipated performance.
	The income approach methodology is applied to the reporting units’ projected future financial performance.  The impairment review is highly judgmental and involves the use of significant estimates and assumptions.   These estimates and assumptions have a significant impact on the amount of impairment charge recorded, if any.   The discounted cash flow method is dependent upon assumption of future sales trends, market conditions and cash flows of each reporting unit over several years.  Actual cash flows in the future may differ significantly from those previously forecasted.  Other significant assumptions include growth rates and the discount rate applicable to future cash flows.
	During the year ended December 31, 2011, the Company recorded a goodwill impairment charge of $4,945 within the Wiring reportable segment.  The goodwill impairment charge reduced the carrying value of BCS goodwill to $4,173 and was the result of a decline in business activity due to a reduction in military and defense related spending by customers since the Company’s acquisition of BCS.  No impairment was identified in the Wiring segment for the years ended December 31, 2013 or 2012.
	The Company’s accumulated goodwill impairment loss for the years ended December 31, 2013 and 2012 was $253,570.
	Intangible assets, net at December 31, 2013 and 2012 consisted of the following:
			Acquisition		Accumulated
	As of December 31, 2013		cost		amortization		Net
	Customer lists	$	38,451	$	-5,402	$	33,049
	Trademarks		25,572		-2,943		22,629
	Technology		15,111		-1,947		13,164
	Other		57		-57		-
	Total	$	79,191	$	-10,349	$	68,842
			Acquisition		Accumulated
	As of December 31, 2012		cost		amortization		Net
	Customer lists	$	43,973	$	-3,166	$	40,807
	Trademarks		29,252		-1,870		27,382
	Technology		17,323		-1,115		16,208
	Other		66		-66		-
	Total	$	90,614	$	-6,217	$	84,397
	The Company recognized $5,275,  $5,940 and $238 of amortization expense in 2013, 2012 and 2011, respectively.  Amortization expense is included as a component of selling, general and administrative on the consolidated statements of operations.  Amortization expense for intangible assets is estimated to be approximately $5,000 for the years 2014 through 2019 and the weighted-average remaining amortization period is approximately 15 years.
Accrued Expenses and Other Current Liabilities	'
	Accrued Expenses and Other Current Liabilities
	Accrued expenses and other current liabilities consist of the following:
	As of December 31		2013		2012
	Compensation related liabilities	$	24,631	$	22,620
	Product warranty and recall obligations		5,462		5,613
	Other (A)		26,558		28,848
	Total accrued expenses and other current liabilities	$	56,651	$	57,081
	(A)“Other” is comprised of miscellaneous accruals, none of which contributed a significant portion of the total.
Income Taxes	'
	Income Taxes
	The Company accounts for income taxes using the liability method. Deferred income taxes reflect the tax consequences on future years of differences between the tax basis of assets and liabilities and their financial reporting amounts. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not to occur.
	The Company's policy is to provide for uncertain tax positions and the related interest and penalties based upon management's assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities.  At December 31, 2013, the Company believes it has appropriately accounted for any unrecognized tax benefits (see Note 5).  To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company's effective tax rate in a given financial statement period may be affected.
Currency Translation	'
	Currency Translation
	The financial statements of foreign subsidiaries, where the local currency is the functional currency, are translated into U.S. dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for the results of operations.  Adjustments resulting from translation of financial statements are reflected as a component of accumulated other comprehensive loss.  Foreign currency transactions are remeasured into the functional currency using translation rates in effect at the time of the transaction, with the resulting adjustments included on the consolidated statements of operations within other expense, net.  These foreign currency transaction losses, including the impact of hedging activities, were $1,752,  $4,275 and $106 for the years ended December 31, 2013, 2012 and 2011, respectively.
Revenue Recognition and Sales Commitments	'
	Revenue Recognition and Sales Commitments
	The Company recognizes revenues from the sale of products, net of actual and estimated returns, at the point of passage of title, which is either at the time of shipment or upon customer receipt based upon the terms of the sale.  The Company collects certain taxes and fees on behalf of government agencies and remits such collections on a periodic basis.  The taxes are collected from customers but are not included in net sales. Estimated returns are based on historical authorized returns.  The Company often enters into agreements with its customers at the beginning of a given vehicle’s expected production life.  Once such agreements are entered into, it is the Company’s obligation to fulfill the customers’ purchasing requirements for the entire production life of the vehicle.  These agreements are subject to renegotiation, which may affect product pricing.
Shipping and Handling Costs	'
	Shipping and Handling Costs
	Shipping and handling costs are included in cost of goods sold on the consolidated statements of operations.
Product Warranty and Recall Reserves	'
	Product Warranty and Recall Reserves
	Amounts accrued for product warranty and recall claims are established based on the Company’s best estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet dates.  These accruals are based on several factors including past experience, production changes, industry developments and various other considerations.  The Company can provide no assurances that it will not experience material claims in the future or that it will not incur significant costs to defend or settle such claims beyond the amounts accrued or beyond what the Company may recover from its suppliers.  The current portion of the product warranty and recall reserve is included as a component of accrued expenses and other current liabilities on the consolidated balance sheets.  Product warranty and recall includes $1,019 and $494 of a long-term liability at December 31, 2013 and 2012, respectively, which is included as a component of other long-term liabilities on the consolidated balance sheets.
	The following provides a reconciliation of changes in the product warranty and recall reserve:
	Years ended December 31		2013		2012
	Product warranty and recall at beginning of period	$	6,107	$	5,301
	Accruals for products shipped during period		4,793		3,288
	Aggregate changes in pre-existing liabilities due to claim developments		1,715		1,062
	Settlements made during the period (in cash or in kind)		-6,134		-3,544
	Product warranty and recall at end of period	$	6,481	$	6,107
Product Development Expenses	'
	Product Development Expenses
	Expenses associated with the development of new products and changes to existing products are charged to expense as incurred and are included in the Company’s consolidated statements of operations as a component of selling, general and administrative.  These product development costs amounted to $45,261,  $44,798 and $35,263 in years ended December 31, 2013, 2012 and 2011, respectively, or 4.8%,  4.8% and 4.6% of net sales for these respective periods.
Share-Based Compensation	'
	Share-Based Compensation
	At December 31, 2013, the Company had three types of share-based compensation plans: (1) Long-Term Incentive Plan, as amended, (2) Directors’ Share Option Plan and (3) the Amended Directors’ Restricted Shares Plan.  One plan is for employees and two plans are for non-employee directors.  The Long-Term Incentive Plan is made up of the Long-Term Incentive Plan that was approved by the Company's shareholders on September 30, 1997, which expired on June 30, 2007, and the Amended and Restated Long-Term Incentive Plan, as amended, that was approved by shareholders on May 17, 2010, and expires on April 24, 2016.
	Total compensation expense recognized as a component of selling, general and administrative on the consolidated statements of operations for share-based compensation arrangements was $4,974,  $4,890 and $4,423 for the years ended December 31, 2013, 2012 and 2011, respectively.  Of these amounts, $155,  $47 and $375 for the years ended December 31, 2013, 2012 and 2011, respectively, were related to the Long-Term Cash Incentive Plan “Phantom Shares” discussed in Note 8.  There was no share-based compensation expense capitalized in inventory during 2013, 2012 or 2011.
Financial Instruments and Derivative Financial Instruments	'
	Financial Instruments and Derivative Financial Instruments
	Financial instruments, including derivative financial instruments, held by the Company include cash and cash equivalents, accounts receivable, accounts payable, long-term debt, an interest rate swap, fixed price commodity contracts and foreign currency forward contracts. The carrying value of cash and cash equivalents, accounts receivable and accounts payable is considered to be representative of fair value because of the short maturity of these instruments.  See Note 9 for fair value disclosures of the Company’s financial instruments.
Common Shares Held in Treasury	'
	Common Shares Held in Treasury
	The Company accounts for Common Shares held in treasury under the cost method and includes such shares as a reduction of total shareholders’ equity.
Net Income Per Share	'
	Net Income Per Share
	Basic net income per share was computed by dividing net income by the weighted-average number of Common Shares outstanding for each respective period.  Diluted net income per share was calculated by dividing net income by the weighted-average of all potentially dilutive Common Shares that were outstanding during the periods presented.
	Actual weighted-average Common Shares outstanding used in calculating basic and diluted net income per share were as follows:
	Years ended December 31		2013		2012		2011
	Basic weighted-average shares outstanding		26,670,501		26,377,352		24,180,671
	Effect of dilutive securities		522,984		654,518		464,258
	Diluted weighted-average shares outstanding		27,193,485		27,031,870		24,644,929
	Options not included in the computation of diluted net income per share to purchase 20,000,  59,000 and 50,000 Common Shares at an average price of $15.73,  $12.20 and $15.73 per share were outstanding at December 31, 2013, 2012 and 2011, respectively.  These outstanding options were not included in the computation of diluted net income per share because their respective exercise prices were greater than the average closing market price of Company Common Shares.
	There were 663,750,  635,850 and 419,100 performance-based restricted Common Shares outstanding at December 31, 2013, 2012 and 2011, respectively. These shares were not included in the computation of diluted net income per share because all vesting conditions have not been and are not expected to be achieved as of December 31, 2013, 2012 and 2011.  These shares may become dilutive based on the Company’s ability to meet or exceed future performance targets.
Deferred Finance Costs	'
	Deferred Finance Costs
	Deferred finance costs are being amortized over the life of the related financial instrument using the straight-line method, which approximates the effective interest method.  The 2.5% discount to the initial purchasers of the Company’s senior secured notes is being accreted using the effective interest rate of 10.0% over the life of the senior secured notes. Deferred finance cost amortization and debt discount accretion for the years ended December 31, 2013, 2012 and 2011 was $961,  $862 and $875, respectively, and is included as a component of interest expense, net on the consolidated statements of operations.  As of December 31, 2013 and 2012, deferred financing costs, net were $1,168 and $1,564, respectively and were included on the consolidated balance sheets as a component of investments and other long-term assets, net.

	In February 2013, the Financial Accounting Standards Board ("FASB") issued an accounting standards update requiring new disclosures about reclassifications from accumulated other comprehensive loss to net income. These disclosures may be presented on the face of the statements or in the notes to the consolidated financial statements. The standards update is effective for fiscal years beginning after December 15, 2012. We adopted this standards update on January 1, 2013 and revised our disclosures, see above.
