Summary of Significant Accounting Policies and Practices	'
	1)	Summary of Significant Accounting Policies and Practices
		a)	Description of Business
	NN, Inc. (“NN”, “the Company”, “we”, “our” or “us”) is a manufacturer of precision balls, cylindrical and tapered rollers, bearing retainers, plastic injection molded products, precision bearing seals and precision metal components. Our balls, rollers, retainers, and bearing seals are used primarily in the domestic and international anti-friction bearing industry. Our plastic injection molded products are used in the bearing components, automotive components, electronic instrument cases and other molded components used in a variety of applications. The precision metal components products are used in the HVAC, automotive, fluid power and diesel engine industries.
		b)	Cash
	The Company considers all highly liquid investments with an original maturity of three months or less as cash equivalents.
		c)	Inventories
	Inventories are stated at the lower of cost or market. Cost is determined using the average costs method. Our policy is to expense abnormal amounts of idle facility expense, freight, handling cost, and waste. In addition, we allocate fixed production overheads based on the normal production capacity of our facilities. Inventory valuations were developed using normalized production capacities for each of our manufacturing locations and the costs from excess capacity or under-utilization of fixed production overheads were expensed in the period incurred and are not included as a component of inventory valuation.
	Inventories also include tools, molds and dies in progress that we are producing and will ultimately sell to our customers. This activity is principally related to our Plastic and Rubber Components and Precision Metal Components Segments. These inventories are carried at the lower of cost or market.
		d)	Property, Plant and Equipment
	Property, plant and equipment are stated at cost less accumulated depreciation. Assets to be disposed of are stated at lower of depreciated cost or fair market value less estimated selling costs. Expenditures for maintenance and repairs are charged to expense as incurred. Major renewals and betterments are capitalized. When a property item is retired, its cost and related accumulated depreciation are removed from the property accounts and any gain or loss is recorded in the consolidated statements of income and comprehensive income. We review the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Property, plant and equipment includes tools, molds and dies principally used in our Plastic and Rubber Components and Precision Metal Components Segments that are our property.
	Depreciation is provided on the straight-line method over the estimated useful lives of the depreciable assets for financial reporting purposes. For leasehold improvements and buildings under capital lease, we depreciate these over the shorter of useful lives or the lease term. In the event we abandon and cease to use certain property, plant, and equipment, depreciation estimates are revised and, in most cases, depreciation expense will be accelerated to reflect the shortened useful life of the asset.
		e)	Revenue Recognition
	We recognize revenues based on the stated shipping terms with customers when these terms are satisfied and the risks of ownership are transferred to the customers. We have an inventory management program for certain Metal Bearing Components Segment customers whereby revenue is recognized when products are used by customers from consigned stock, rather than at the time of shipment. Under both circumstances, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sellers’ price is fixed and determinable and collectability is reasonably assured.
		f)	Accounts Receivable
	Accounts receivable are recorded upon recognition of a sale of goods and ownership and risk of loss is assumed by the customer. Substantially all of our accounts receivable are due primarily from the core served markets. In establishing allowances for doubtful accounts, we perform credit evaluations of our customers, considering numerous inputs when available including the customers’ financial position, past payment history, relevant industry trends, cash flows, management capability, historical loss experience and economic conditions and prospects. Accounts receivable are written off or allowances established when considered to be uncollectible or at risk of being uncollectible, respectively.
		g)	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has not been made for income taxes on unremitted earnings of foreign subsidiaries as these earnings are deemed to be permanently reinvested. We recognize income tax positions that meet the more likely than not threshold and accrue interest and potential penalties related to unrecognized income tax positions which are recorded as a component of the provision (benefit) for income taxes.
		h)	Net Income Per Common Share
	Basic income per share reflects reported earnings divided by the weighted average number of common shares outstanding. Diluted income per share include the effect of dilutive stock options, unvested restricted stock (if any) and the respective tax benefits, unless inclusion would not be dilutive.
		i)	Share Based Compensation
	The cost of stock options and stock awards are expensed as compensation expense over the vesting periods based on the fair value at the grant date. (See Note 8 of the Notes to the Consolidated Financial Statements) We use the Black Scholes financial pricing model to determine the fair value of our stock options as our options are not traded in open markets.
	We account for stock awards by recognizing compensation expense ratably over the vesting period as specified in the award. Compensation expense to be recognized is based on the stock price at date of grant.
		j)	Principles of Consolidation
	Our consolidated financial statements include the accounts of NN, Inc. and its subsidiaries. All of our subsidiaries are 100% owned and all are included in the consolidated financial statements for the years end December 31, 2013, 2012, and 2011. All significant inter-company profits, transactions, and balances have been eliminated in consolidation.
		k)	Foreign Currency Translation
	Assets and liabilities of our foreign subsidiaries are translated at current exchange rates, while revenue, costs and expenses are translated at average rates prevailing during each reporting period. Translation adjustments arising from the translation of foreign subsidiary financial statements are reported as a component of other comprehensive income and accumulated other comprehensive income within stockholders’ equity. In addition, transactions denominated in foreign currencies, including intercompany transactions, are initially recorded at the current exchange rate at the date of the transaction. The balances are adjusted to the current exchange rate as of each balance sheet date and as of the date when the transaction is consummated. Transaction gains or losses, excluding intercompany loan transactions, are expensed in either cost of products sold or selling, general and administrative lines in the Consolidated Statements of Comprehensive Income as incurred and were immaterial to the years ended December 31, 2013, 2012 and 2011. Transaction gains or losses on intercompany loan transactions are recognized in the other income, net line in the Consolidated Statements of Comprehensive Income as incurred.
		l)	Goodwill and Other Indefinite Lived Intangible Assets
	We recognize the excess of the purchase price of an acquired entity over the fair value of the net identifiable assets as goodwill. Goodwill is tested for impairment on an annual basis as of October 1 and between annual tests if a triggering event occurs. The impairment procedures are performed at the reporting unit level for the one reporting unit that still has goodwill. In September 2011, the FASB issued a revised accounting standard, intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. For the years ended, December 31, 2013 and 2012, we determined it was more appropriate to perform a full step 1 goodwill test. The decision to perform a qualitative assessment or a complete step 1 analysis is an annual decision made by management. Based on the result of the step 1 analysis fair value of the reporting unit exceeded the carrying value of the reporting unit at December 31, 2013 and 2012.
	If the qualitative assessment indicates it is more likely than not that the fair value is less than the carrying value, U.S. GAAP prescribes a two-step process for testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. The fair value of the reporting unit is determined through use of discounted cash flow methods and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the unit tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs) the calculation of fair value for goodwill would be most consistent with Level 3 inputs.
	If the carrying value of the reporting unit including goodwill is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value.
	We base our fair value estimates, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material.
	Our indefinite lived intangible asset is accounted for similarly to goodwill. This asset is tested for impairment at least annually by comparing the fair value to the carrying value, using the relief from royalty rate method, and if the fair value is less than the carrying value, an impairment charge is recognized for the difference. We elected to use Step 1 testing even though a qualitative approach was available to us.
		m)	Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of
	Long-lived tangible and intangible assets subject to amortization are tested for recoverability when changes in circumstances indicate the carrying value of these assets may not be recoverable. A test for recoverability is also performed when management has committed to a plan to dispose of a reporting unit or asset group. Assets to be held and used are tested for recoverability when indications of impairment are evident. Recoverability of a long-lived tangible and intangible asset is evaluated by comparing its carrying value to the future estimated undiscounted cash flows expected to be generated by the asset or asset group. If the asset is not recoverable the asset is considered impaired and adjusted to fair value which is then depreciated/amortized over its remaining useful life. Assets to be disposed of are carried at the lesser of carrying value or fair value less costs of disposal. (See Note 2 of the Notes to Consolidated Financial Statements).
		n)	Use of Estimates in the Preparation of Financial Statements
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
		o)	Fair Value Measurements
	Fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
		p)	Reclassifications
	Certain 2012 and 2011 amounts have been reclassified to conform with 2013 presentation.
		q)	Recently Issued Accounting Standards
	In February 2013, the Financial Accounting Standards Board issued accounting guidance to enhance the disclosure of amounts reclassified out of accumulated other comprehensive income. The new disclosure guidelines require the presentation of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income in the event the amount reclassified is required to be reclassified in its entirety in the same reporting period. The presentation can be on the face of the statement where net income is presented or in the notes and reported by component. For amounts not required to be reclassified in its entirety in the same reporting period to net income, an entity is required to cross-reference other required disclosures. This guidance is effective for reporting periods beginning after December 15, 2012. We have concluded that the new guidance did not have an impact on our financial position or results of operations.
	In March 2013, the Financial Accounting Standards Board issued amended accounting guidance that addresses the release of cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business (other than an in-substance real estate sale or oil/gas mineral rights) within a foreign entity. The cumulative translation adjustments should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Additionally, in the event of a step acquisition when the acquirer obtains control of an acquiree in which it held an equity interest immediately prior to the acquisition, the cumulative translation adjustments would be released into net income. This guidance is effective prospectively for reporting periods beginning after December 15, 2013. We have concluded that the new guidance will not have an impact on our financial position or results of operations.

	Impairments of Goodwill and Other Long-Lived Tangible and Intangible Assets
	For the year ended December 31, 2012, we recorded $967 of non-cash charges related to the further impairment of our former production facility in Kilkenny, Ireland. Based on updated market based information related to commercial property valuation in Ireland, management determined the market value of the building was less than book value and the book value was adjusted accordingly. This impairment charge was reported in the Restructuring and Impairment Charges line as a component of income from operations in 2012.

	Long-term debt at December 31, 2013 and 2012 consisted of the following:
			2013			2012
	Borrowings under our $100,000 revolving credit facility bearing interest at a floating rate equal to LIBOR (0.1875% at December 31, 2013) plus an applicable margin of 1.25%, expiring October 26, 2017.		$	10,763		$	38,087
	Borrowings under our $40,000 aggregate principal amount notes bearing interest at a fixed rate of 4.89% maturing on April 26, 2014. Annual principal payments of $5,714 began on April 26, 2008 and extend through the date of maturity.			5,714			11,429
	Borrowings under our $20,000 aggregate principal amount notes bearing interest at a fixed rate of 4.64% maturing on December 20, 2018. Annual principal payments of $4,000 will begin on December 22, 2014 and extend through the date of maturity.			20,000			20,000
	Total long-term debt			36,477			69,516
	Less current maturities of long-term debt			10,477			5,801
	Long-term debt, excluding current maturities		$	26,000		$	63,715
	On October 26, 2012, we amended our $100,000 revolving credit facility agented by KeyBank and our fixed rate notes with Prudential Capital in order to take advantage of lower interest rates, to extend the maturity of the revolving credit facility to October 26, 2017, and to remove certain restrictions on acquisitions, payments of dividends and stock repurchases. The amended interest rates on our revolving credit facility are LIBOR plus an applicable margin ranging from 1.25% to 2.25% (depending on the level of debt to earnings before taxes, interest and depreciation (“EBITDA”)). Prior to the October 26, 2012 amendment, the $100 million revolving credit facility interest rates were LIBOR plus a margin ranging from 2.50% to 3.50% (depending on the level of debt to EBITDA). The interest rate on our $40,000 aggregate fixed rate notes, of which $5,714 was outstanding as of December 31, 2013, was reduced from 5.39% to 4.89%. The amended agreements allow us to undertake acquisitions, pay dividends, and repurchase stock provided we are in compliance with specified covenants. Additionally, the minimum fixed charge coverage ratio will remain at “not to be less than 1.00 to 1.00 as of the last day of any fiscal quarter” for the full terms of the amended agreements.
	The $100,000 revolving credit facility may be expanded upon our request with approval of the lenders by up to $35,000 under the same terms and conditions. The loan agreement contains customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and merger, acquisition and other fundamental changes in our business including a “material adverse change” clause, which if triggered would accelerate the maturity of the debt. The facility has a $10,000 swing line feature to meet short term cash flow needs. Any borrowings under this swing line are considered short term. Costs associated with entering into the revolving credit facility and the subsequent amendments were capitalized and will be amortized into interest expense over the life of the facility. As of December 31, 2013 and 2012, $1,617 and $2,012, respectively, of net capitalized loan origination costs related to the revolving credit facility were recorded on the consolidated balance sheet within other non-current assets.
	The $40,000 and $20,000 fixed rate agreements contain customary restrictions on, among other things, additional indebtedness, liens on our assets, sales or transfers of assets, investments, issuance of equity securities, and mergers, acquisitions and other fundamental changes in our business including a “material adverse change” clause, which if triggered would accelerate the maturity of the debt. We incurred costs as a result of issuing these notes and the subsequent amendments which have been recorded as a component of other non-current assets and are being amortized over the term of the notes. The unamortized balance at December 31, 2013 and 2012 was $34 and $157, respectively.
	The aggregate maturities of long-term debt including current portion for each of the five years subsequent to December 31, 2013 are as follows:

Employee Benefit Plans	'
	7)	Employee Benefit Plans
	We have defined contribution 401(k) profit sharing plans covering substantially all U.S. employees. All employees are eligible for the plans on the first day of the month following their employment date. A participant may elect to contribute between 1% and 60% of their compensation to the plans, subject to Internal Revenue Service (“IRS”) dollar limitations. Participants age 50 and older may defer an additional amount up to the applicable IRS Catch Up Provision Limit. We provide a matching contribution which is determined on an individual, participating company basis. All participant contributions are immediately vested at 100%. Contributions for all U.S. employees were $349, $335 and $334 in 2013, 2012, and 2011, respectively.
	Post-Employment Benefit Liabilities
	We provide certain post-employment benefits to employees at our Pinerolo and Veenendaal plants that are either required by law or are local labor practice. There is a plan at our Pinerolo Plant and at our Veenendaal Plant which are described below.
	In accordance with Italian law, the Company has an unfunded severance plan under which all Italian employees are entitled to receive severance indemnities (Trattamento di Fine Rapporto or “TFR”) upon termination of their employment.
	Effective January 1, 2007, the amount payable based on salary paid is remitted to a pension fund managed by a third party. The severance indemnities paid to the pension fund accrue approximately at the rate of 1/13.5 of the gross salaries paid during the year. The amounts accrued become payable upon termination of the individual employee, for any reason, e.g., retirement, dismissal or reduction in work force. Employees are fully vested in TFR benefits after their first year of service.
	We have a plan that covers our Veenendaal Plant employees that provides an award for employees who achieve 25 or 40 years of service and an award for employees upon retirement. The plan is unfunded and the benefits are based on years of service and rate of compensation at the time the award is paid.
	The amounts shown in the table below represent the actual liabilities at December 31, 2013 and 2012 reported under accrued post-employment benefits in the Consolidated Balance Sheets for both plans combined.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]	'
Stock Based Compensation	'
	8)	Stock Based Compensation
	We recognize compensation expense of all employee and non-employee director share-based compensation awards in the financial statements based upon the fair value of the awards over the requisite service or vesting period, less anticipated forfeitures. We account for stock awards by recognizing the fair value of the awarded stock at the grant date as compensation expense over the vesting period, less anticipated forfeitures.
	In the years ended December 31, 2013, 2012, and 2011, approximately $2,239, $1,788, and $828, respectively of compensation expense was recognized in selling, general and administrative expense for all share-based awards. The compensation expense recognized in the years ended December 31, 2013, 2012 and 2011 related to stock options was $1,437, $1,093, and $480, respectively. The compensation expense related to stock awards in the years ended December 31, 2013, 2012 and 2011 was $802, $695, and $348, respectively.
	During the year ended December 31, 2011, our shareholders approved a new stock based compensation plan totaling 2,500 shares that can be issued in the form of stock options, stock appreciation rights and/or other stock based awards. Any options issued count as the equivalent of one share under the plan. Any stock appreciation rights and/or other stock based awards count as the equivalent one and a half shares under the new plan. As of December 31, 2013, we have approximately 1,361 maximum shares that can be issued as options, stock appreciation rights, and/or other stock based awards. Under our previously approved plan, we still have 52 options available for issuance.
	Stock Option Awards
	Option awards are typically granted to non-employee directors and key employees on an annual basis. A single option grant is typically awarded to eligible employees and non-employee directors each year if and when granted by the Compensation Committee of the Board of Directors and occasionally individual grants are awarded to eligible employees. All employee and non-employee directors are awarded options at an exercise price equal to the closing price of our stock on the date of grant. The term life of options is ten years with vesting periods of generally three years for key employees and one year for non-employee directors. The fair value of our options cannot be determined by market value as they are not traded in an open market. Accordingly, the Black Scholes financial pricing model is utilized to determine fair value based on certain assumptions discussed below.
	During 2013, 2012 and 2011, we granted 354, 285, and 216 options, respectively, to certain key employees and non-employee directors. The weighted average grant date fair value of the options granted during the years ended December 31, 2013, 2012 and 2011 was $5.17, $4.27, and $5.98, respectively. Upon exercise of stock options, new shares of our stock are issued. The weighted average assumptions relevant to determining the fair value at the dates of grant are below:
			2013			2012			2011
	Term			6 years			6 years			6 years
	Risk free interest rate			0.87	%		1.16	%		1.72	%
	Dividend yield			0	%		0	%		0	%
	Expected volatility			57	%		50.51	%		42.1	%
	Expected forfeiture rate			3	%		3	%		5	%
	The expected volatility rate is derived from our actual common stock historical volatility over the same time period as the expected term. The volatility rate is derived by mathematical formula utilizing daily closing price data.
	The expected dividend yield is derived by a mathematical formula which uses the expected annual dividends over the expected term divided by the fair market value of our common stock at the grant date.
	The average risk-free interest rate is derived from United States Department of Treasury published interest rates of daily yield curves for the same time period as the expected term.
	The forfeiture rate is determined from examining the historical pre-vesting forfeiture patterns of past option issuances to key employees. The forfeiture rate is estimated to be 0% for non-employee directors. While the forfeiture rate is not an input of the Black Scholes model for determining the fair value of the options, it is an important determinant of stock option compensation expense to be recorded.
	The term is derived from using the “Simplified Method” of determining stock option terms as described under the Securities and Exchange Commission’s Staff Accounting Bulletin 107.
	The following table provides a reconciliation of option activity for the year ended December 31, 2013:
	Options		Shares			Weighted-			Weighted-			Aggregate
			(000’s)			Average			Average			Intrinsic
						Exercise			Remaining			Value
						Price			Contractual			$0
									Term
	Outstanding at January 1, 2013			1,384		$	9.94
	Granted			354		$	9.81
	Exercised			(496	)	$	8.1
	Forfeited or expired			(9	)	$	9.36
	Outstanding at December 31, 2013			1,233		$	10.65			6.5		$	11,762	(1)
	Exercisable at December 31, 2013			687		$	11.22			4.6		$	6,168	(1)
	(1)	The intrinsic value is the amount by which the market price of our stock was greater than the exercise price of any individual option grant at December 31, 2013.
	As of December 31, 2013, there was approximately $1,151 and $633 of unrecognized compensation costs for stock options and restricted stock, respectively, to be recognized over approximately two years.
	Cash proceeds from the exercise of options in the years ended December 31, 2013, 2012, and 2011 totaled approximately $4,013, $22, and $2,382, respectively. For the years ended December 31, 2013, 2012 and 2011, proceeds from stock options were presented exclusive of tax benefits in the Financing Activities section of the Consolidated Statements of Cash Flows. The total intrinsic value of options exercised during the years ended December 31, 2013, 2012 and 2011 was $1,416, $107, and $1,283, respectively.
	Stock Awards
	During the year ended December 31, 2013, 2012 and 2011, we issued 90, 78 and 75 shares, respectively, of our common stock as awards to key employees and non-executive directors. The fair value of the shares issued was determined by using the grant date price of our common stock with a weighted average grant date value of $9.82. The recognized compensation expense for stock awards in the years ended December 31, 2013, 2012, and 2011 was approximately $802, $695, and $348, respectively. The shares issued in 2013, 2012 and 2011 vest over three years.

	Prior to December 31, 2012, we had full valuation allowances against all the deferred tax assets of our U.S. units as we had determined that it was more likely than not the U.S. locations would be unable to generate sufficient profits to allow realization of existing deferred tax assets at those period ends. The determination to place a valuation allowance on the tax benefits incurred by our U.S. based operations was made during 2009 due to the 2009 results of these entities being much more unfavorable than originally forecasted during the global economic recession of 2009. While our U.S. entities generated pre-tax income of $1,633 during the year ended December 31, 2011, the substantial cumulative losses in 2009 and 2010 outweighed the positive evidence of the 2011 taxable income.
	For the year ended 2012, the pretax profit of our U.S. based companies increased to approximately $7,400 due in large part to the operational improvements in our Precision Metal Components Segment. This brought the combined 2012 and 2011 pre-tax incomes to approximately $9,000. Additionally, during the fourth quarter of 2012, we utilized approximately $9,000 of net operating losses to offset tax expense related to certain previously earned income of our foreign holding company, as discussed below. This positive evidence coupled with estimates within our U.S. based businesses of fully utilizing our net operating losses within the next two years provided enough positive evidence, in the opinion of management, to overcome the negative evidence of the cumulative pre-tax losses in 2009 and 2010. Accordingly in 2012, after considering all relevant factors and objectively verifiable evidence having an impact on the likelihood of future realization of our U.S. companies’ deferred tax assets, as of December 31, 2012, management concluded that it is more likely than not that the majority of our deferred tax assets will be realized in future years. Accordingly, we reversed $8,512 of the amount of the valuation allowance on our tax effected deferred tax assets, with a credit to the provision for income taxes of $8,512 in our Consolidated Statements of Income and Comprehensive Income.
	A valuation allowance of $1,434 will remain offsetting certain deferred tax assets as of December 31, 2013. These assets represent the portion of our previously recognized foreign tax credits which management estimates will not be realized in the future due to their relatively short remaining carry-forward periods. During the year ended December 31, 2013, we reduced the valuation allowance against these credits by $818 related to credits which expired as of December 31, 2013.
	The following tables reflect the effects of full valuation allowances on the net deferred tax assets of all U.S. based entities for the year ended December 31, 2011, the removal of $9,814 of these valuation allowances for the year ended December 31, 2012, and recognizing full tax expenses at all jurisdictions for the year ended December 31, 2013.
	Income before provision (benefit) for income taxes for the years ended December 31, 2013, 2012 and 2011 was as follows:
			Year ended December 31,

			$	8,000		$	(3,927	)	$	5,168
	During the year ended December 31, 2011, the decrease in the foreign valuation allowance was due to utilizing the net operating losses at certain foreign jurisdictions and to eliminating the valuation allowance on deferred tax assets at our Kysucke (Slovakia) Plant.
	The tax effects of the temporary differences as of December 31, 2013, 2012 and 2011 are as follows:
			December 31,

Net deferred income tax assets (liabilities)		$	988		$	4,319		$	(2,748	)
As realization of certain deferred tax assets is not assured, management has placed valuation allowances against deferred tax assets it believes are not recoverable, as discussed above. For the remainder, management believes it is more likely than not that those net deferred tax assets will be realized. However, the amount of the deferred tax assets considered realizable could be reduced based on changing conditions. Below is a summary of the activity in the total valuation allowances during the years ended December 31, 2013, 2012 and 2011:
		Total Valuation Allowance Activity
		Balance at			Additions			Recoveries			Deconsolidation			Balance at End
		Beginning of									of Eltmann			of Year
		Year									subsidiary
2013		$	2,252		$	—		$	(818	)	$	—		$	1,434
2012		$	12,066		$	—		$	(9,814	)	$	—		$	2,252
2011		$	16,604		$	—		$	(2,425	)	$	(2,113	)	$	12,066
The net operating loss carry forwards as of December 31, 2013, are composed of net operating losses at our U.S. operations during 2010, 2009 and 2008. The losses of the U.S. based entities can be carried forward 20 years.
The foreign tax credits relate to profits of certain foreign subsidiaries that were taxed as deemed dividends. These credits represent the foreign taxes paid by these subsidiaries at higher effective rates that will be used to offset future foreign source income. A full valuation allowance was placed against these credits as of December 31, 2008, based on estimates, at that time, of future levels of U.S. income tax and foreign source income to be generated that these credits could be used to offset. The valuation allowance will be periodically reviewed as our estimates of future foreign source income are revised based on actual foreign source income recognized in our tax returns and future changes in foreign source income. As of December 31, 2013 and 2012, management believed it was more likely than not we would only utilize $1,592 and $1,592, respectively, of these credits in the near future and placed a valuation allowance on the remaining $1,434 and $2,252, respectively.
As of December 31, 2006, all of the Company’s foreign earnings had been previously taxed in the U.S. due to the application of IRC Sec. 956. Accordingly, no deferred taxes have been provided for undistributed earnings up to that time.
On December 27, 2012, our foreign holding company declared a distribution of approximately $48,000 to its U.S. parent company NN, Inc. The vast majority of this distribution was a proportional return of investment basis in our Western European subsidiaries. Approximately $9,000 of the distribution pertained to earnings and profits earned by this holding company in previous years. The approximately $9,000 of earning and profits was included in our computation of year ended 2012 taxes and the tax rate resulting in an impact of $3,079. There were two main factors influencing our decision to consider this return of basis. First, there was a desire to reduce the amount of basis in our European subsidiaries recorded on the U.S. parent company’s financial statements considering the downsizing of our European production capacity over the last few years. The second factor was proposed federal tax legislation which, if enacted, could significantly increase the tax cost of returning this basis after 2012. Because there had been no change in our long term international expansion plans as of December 31, 2013, our intent to indefinitely reinvest foreign earnings accumulated through the year ended December 31, 2013 was not changed by these factors. As of the year ended December 31, 2013, we intend to keep indefinitely reinvesting our foreign earnings. We base this assertion on two factors. First, our intention to invest in foreign countries that are strategically important to our Metal Bearing Components Segment business and its customers. Second, we have sufficient access to funds in the U.S. through projected free cash flows and the availability of our credit facilities to fund currently anticipated domestic operational and investment needs.
As such, we do not expect unrepatriated foreign earnings to become subject to U.S. taxation in the foreseeable future. If such earnings were distributed beyond the amount for which taxes have been provided, foreign tax credits would substantially offset the incremental U.S. tax liability. A deferred tax liability will be recognized should we expect we will recover these undistributed earnings in a taxable manner, such as through the receipt of dividends or sale of the investments. As we presently plan to permanently reinvest foreign undistributed earnings, we have not provided for U.S. income tax liabilities that would be payable if such earnings were not reinvested indefinitely. It is not practicable to determine the amount of unrecognized deferred tax liability related to the unremitted earnings.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding interest and penalties for the years ended December 31, 2013, 2012 and 2011 is as follows:
		2013			2012			2011
Beginning balance		$	873		$	988		$	953
Additions for tax positions of prior years			—			428			35
Reductions for tax positions of prior years			—			(543	)		—
Ending balance		$	873		$	873		$	988
As of December 31, 2013, the $873 of unrecognized tax benefits would, if recognized, impact our effective tax rate.
Interest and penalties related to federal, state, and foreign income tax matters are recorded as a component of the provision for income taxes in our statements of income. During 2013, we accrued $32 in foreign interest and penalties. During 2012, we had an increase in foreign interest and penalties of $443 and a decrease in federal and state interest and penalties of $245 as older uncertain items were eliminated due to the tax years being closed or risk being mitigated. During 2011, we had a net reduction in foreign interest and penalties of $43 as older uncertain items were eliminated and newer uncertain items added. As of December 31, 2013, the total amount accrued for interest and penalties was $1,020.
We or our subsidiaries file income tax returns in the U.S. federal jurisdiction, and in various states and foreign jurisdictions. With few exceptions, we are no longer subject to federal, state and local income tax examinations by tax authorities for years before 2010. We are no longer subject to non-U.S. income tax examinations within various European Union countries for years before 2008. We do not foresee any significant changes to our unrecognized tax benefits within the next twelve months.

	All legal proceedings are of an ordinary and routine nature and are incidental to our operations. Management believes that such proceedings should not, individually or in the aggregate, have a material adverse effect on our business, financial condition, results of operations, or cash flows. In making that determination, we analyze the facts and circumstances of each case at least quarterly in consultation with our attorneys and determine a range of reasonably possible outcomes. The procedures performed include reviewing attorney and plaintiff correspondence, reviewing any filings made and discussing the facts of the case with local management and legal counsel We have recognized loss contingencies of approximately $200 and $500 at December 31, 2013 and December 31, 2012, respectively, which we believe are adequate to cover all probable liabilities to be incurred by all of the cases in the aggregate.
	Due to the impacts of the global economic recession and the resulting reduction in revenue and operating losses, our wholly owned German subsidiary Kugelfertigung Eltmann GbmH (“Eltmann” or “Eltmann Plant”) sustained a significant weakening of its financial condition and as a result, became technically insolvent at which point it was required to file for bankruptcy under German bankruptcy law. The filing was made in the bankruptcy court in Germany on January 20, 2011. As of this date, NN lost the ability to control or manage Eltmann as a result of the bankruptcy court trustee taking over effective control and day to day management of this subsidiary. As a result of loss of control of this subsidiary, NN deconsolidated the assets and liabilities of Eltmann from our Consolidated Financial Statements effective January 20, 2011. Although the bankruptcy trustee released us from all claims related to the Eltmann bankruptcy, effective October 15, 2013, until such court proceedings are finalized, we will not be able to determine definitively if any related liabilities and contingent obligations will remain our responsibility. The ultimate impact on NN of Eltmann filing for bankruptcy will depend on the findings of the bankruptcy court. However, until such court proceedings are finalized, we will not be able to determine what liabilities and contingent obligations, if any, might remain as the responsibility of NN. Under advice from legal counsel, NN does not expect any further significant impacts on our consolidated financial statements as a result of the liquidation of this subsidiary.

	We believe the fair value of financial instruments with maturities of less than a year approximate their carrying value due to the short maturity of these instruments or in the case of our variable rate debt, due to the variable interest rates. We elected not to measure any of our financial instruments at fair value and as such will continue to show the fair value of our financial instruments for disclosure purposes only. The fair value of our fixed rate long-term borrowings is calculated using significant other observable inputs (Level 2 inputs). The fair value is calculated using a discounted cash flow analysis factoring in current market borrowing rates for similar types of borrowing arrangements under our credit profile. The carrying amounts and fair values of our long-term debt are in the table below (for disclosure purposes only):

During the year ended December 31, 2011, we had other comprehensive loss of ($2,578) due to foreign currency translations. Income taxes on the foreign currency translation adjustments in other comprehensive income were not recognized because the earnings are intended to be indefinitely reinvested in those operations.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Description of Business	'
		a)	Description of Business
	NN, Inc. (“NN”, “the Company”, “we”, “our” or “us”) is a manufacturer of precision balls, cylindrical and tapered rollers, bearing retainers, plastic injection molded products, precision bearing seals and precision metal components. Our balls, rollers, retainers, and bearing seals are used primarily in the domestic and international anti-friction bearing industry. Our plastic injection molded products are used in the bearing components, automotive components, electronic instrument cases and other molded components used in a variety of applications. The precision metal components products are used in the HVAC, automotive, fluid power and diesel engine industries.
Cash	'
		b)	Cash
	The Company considers all highly liquid investments with an original maturity of three months or less as cash equivalents.
Inventories	'
		c)	Inventories
	Inventories are stated at the lower of cost or market. Cost is determined using the average costs method. Our policy is to expense abnormal amounts of idle facility expense, freight, handling cost, and waste. In addition, we allocate fixed production overheads based on the normal production capacity of our facilities. Inventory valuations were developed using normalized production capacities for each of our manufacturing locations and the costs from excess capacity or under-utilization of fixed production overheads were expensed in the period incurred and are not included as a component of inventory valuation.
	Inventories also include tools, molds and dies in progress that we are producing and will ultimately sell to our customers. This activity is principally related to our Plastic and Rubber Components and Precision Metal Components Segments. These inventories are carried at the lower of cost or market.
Property, Plant and Equipment	'
		d)	Property, Plant and Equipment
	Property, plant and equipment are stated at cost less accumulated depreciation. Assets to be disposed of are stated at lower of depreciated cost or fair market value less estimated selling costs. Expenditures for maintenance and repairs are charged to expense as incurred. Major renewals and betterments are capitalized. When a property item is retired, its cost and related accumulated depreciation are removed from the property accounts and any gain or loss is recorded in the consolidated statements of income and comprehensive income. We review the carrying values of long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Property, plant and equipment includes tools, molds and dies principally used in our Plastic and Rubber Components and Precision Metal Components Segments that are our property.
	Depreciation is provided on the straight-line method over the estimated useful lives of the depreciable assets for financial reporting purposes. For leasehold improvements and buildings under capital lease, we depreciate these over the shorter of useful lives or the lease term. In the event we abandon and cease to use certain property, plant, and equipment, depreciation estimates are revised and, in most cases, depreciation expense will be accelerated to reflect the shortened useful life of the asset.
Revenue Recognition	'
		e)	Revenue Recognition
	We recognize revenues based on the stated shipping terms with customers when these terms are satisfied and the risks of ownership are transferred to the customers. We have an inventory management program for certain Metal Bearing Components Segment customers whereby revenue is recognized when products are used by customers from consigned stock, rather than at the time of shipment. Under both circumstances, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sellers’ price is fixed and determinable and collectability is reasonably assured.
Accounts Receivable	'
		f)	Accounts Receivable
	Accounts receivable are recorded upon recognition of a sale of goods and ownership and risk of loss is assumed by the customer. Substantially all of our accounts receivable are due primarily from the core served markets. In establishing allowances for doubtful accounts, we perform credit evaluations of our customers, considering numerous inputs when available including the customers’ financial position, past payment history, relevant industry trends, cash flows, management capability, historical loss experience and economic conditions and prospects. Accounts receivable are written off or allowances established when considered to be uncollectible or at risk of being uncollectible, respectively.
Income Taxes	'
		g)	Income Taxes
	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has not been made for income taxes on unremitted earnings of foreign subsidiaries as these earnings are deemed to be permanently reinvested. We recognize income tax positions that meet the more likely than not threshold and accrue interest and potential penalties related to unrecognized income tax positions which are recorded as a component of the provision (benefit) for income taxes.
Net Income Per Common Share	'
		h)	Net Income Per Common Share
	Basic income per share reflects reported earnings divided by the weighted average number of common shares outstanding. Diluted income per share include the effect of dilutive stock options, unvested restricted stock (if any) and the respective tax benefits, unless inclusion would not be dilutive.
Share Based Compensation	'
		i)	Share Based Compensation
	The cost of stock options and stock awards are expensed as compensation expense over the vesting periods based on the fair value at the grant date. (See Note 8 of the Notes to the Consolidated Financial Statements) We use the Black Scholes financial pricing model to determine the fair value of our stock options as our options are not traded in open markets.
	We account for stock awards by recognizing compensation expense ratably over the vesting period as specified in the award. Compensation expense to be recognized is based on the stock price at date of grant.
Principles of Consolidation	'
		j)	Principles of Consolidation
	Our consolidated financial statements include the accounts of NN, Inc. and its subsidiaries. All of our subsidiaries are 100% owned and all are included in the consolidated financial statements for the years end December 31, 2013, 2012, and 2011. All significant inter-company profits, transactions, and balances have been eliminated in consolidation.
Foreign Currency Translation	'
		k)	Foreign Currency Translation
	Assets and liabilities of our foreign subsidiaries are translated at current exchange rates, while revenue, costs and expenses are translated at average rates prevailing during each reporting period. Translation adjustments arising from the translation of foreign subsidiary financial statements are reported as a component of other comprehensive income and accumulated other comprehensive income within stockholders’ equity. In addition, transactions denominated in foreign currencies, including intercompany transactions, are initially recorded at the current exchange rate at the date of the transaction. The balances are adjusted to the current exchange rate as of each balance sheet date and as of the date when the transaction is consummated. Transaction gains or losses, excluding intercompany loan transactions, are expensed in either cost of products sold or selling, general and administrative lines in the Consolidated Statements of Comprehensive Income as incurred and were immaterial to the years ended December 31, 2013, 2012 and 2011. Transaction gains or losses on intercompany loan transactions are recognized in the other income, net line in the Consolidated Statements of Comprehensive Income as incurred.
Goodwill and Other Indefinite Lived Intangible Assets	'
		l)	Goodwill and Other Indefinite Lived Intangible Assets
	We recognize the excess of the purchase price of an acquired entity over the fair value of the net identifiable assets as goodwill. Goodwill is tested for impairment on an annual basis as of October 1 and between annual tests if a triggering event occurs. The impairment procedures are performed at the reporting unit level for the one reporting unit that still has goodwill. In September 2011, the FASB issued a revised accounting standard, intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. Specifically, an entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. For the years ended, December 31, 2013 and 2012, we determined it was more appropriate to perform a full step 1 goodwill test. The decision to perform a qualitative assessment or a complete step 1 analysis is an annual decision made by management. Based on the result of the step 1 analysis fair value of the reporting unit exceeded the carrying value of the reporting unit at December 31, 2013 and 2012.
	If the qualitative assessment indicates it is more likely than not that the fair value is less than the carrying value, U.S. GAAP prescribes a two-step process for testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. The fair value of the reporting unit is determined through use of discounted cash flow methods and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the unit tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs) the calculation of fair value for goodwill would be most consistent with Level 3 inputs.
	If the carrying value of the reporting unit including goodwill is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value.
	We base our fair value estimates, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material.
	Our indefinite lived intangible asset is accounted for similarly to goodwill. This asset is tested for impairment at least annually by comparing the fair value to the carrying value, using the relief from royalty rate method, and if the fair value is less than the carrying value, an impairment charge is recognized for the difference. We elected to use Step 1 testing even though a qualitative approach was available to us.
Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of	'
		m)	Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of
	Long-lived tangible and intangible assets subject to amortization are tested for recoverability when changes in circumstances indicate the carrying value of these assets may not be recoverable. A test for recoverability is also performed when management has committed to a plan to dispose of a reporting unit or asset group. Assets to be held and used are tested for recoverability when indications of impairment are evident. Recoverability of a long-lived tangible and intangible asset is evaluated by comparing its carrying value to the future estimated undiscounted cash flows expected to be generated by the asset or asset group. If the asset is not recoverable the asset is considered impaired and adjusted to fair value which is then depreciated/amortized over its remaining useful life. Assets to be disposed of are carried at the lesser of carrying value or fair value less costs of disposal. (See Note 2 of the Notes to Consolidated Financial Statements).
Use of Estimates in the Preparation of Financial Statements	'
		n)	Use of Estimates in the Preparation of Financial Statements
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements	'
		o)	Fair Value Measurements
	Fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
Reclassifications	'
		p)	Reclassifications
	Certain 2012 and 2011 amounts have been reclassified to conform with 2013 presentation.
Recently Issued Accounting Standards	'
	q)	Recently Issued Accounting Standards
	In February 2013, the Financial Accounting Standards Board issued accounting guidance to enhance the disclosure of amounts reclassified out of accumulated other comprehensive income. The new disclosure guidelines require the presentation of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income in the event the amount reclassified is required to be reclassified in its entirety in the same reporting period. The presentation can be on the face of the statement where net income is presented or in the notes and reported by component. For amounts not required to be reclassified in its entirety in the same reporting period to net income, an entity is required to cross-reference other required disclosures. This guidance is effective for reporting periods beginning after December 15, 2012. We have concluded that the new guidance did not have an impact on our financial position or results of operations.
	In March 2013, the Financial Accounting Standards Board issued amended accounting guidance that addresses the release of cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business (other than an in-substance real estate sale or oil/gas mineral rights) within a foreign entity. The cumulative translation adjustments should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Additionally, in the event of a step acquisition when the acquirer obtains control of an acquiree in which it held an equity interest immediately prior to the acquisition, the cumulative translation adjustments would be released into net income. This guidance is effective prospectively for reporting periods beginning after December 15, 2013. We have concluded that the new guidance will not have an impact on our financial position or results of operations.
