Interim Financial Statements	'
	Note 1. Interim Financial Statements
	The accompanying condensed consolidated financial statements of NN, Inc. have not been audited, except that the condensed consolidated balance sheet at December 31, 2013 was derived from our audited consolidated financial statements. In our opinion, these financial statements reflect all adjustments necessary to fairly state the results of operations for the three and nine month periods ended September 30, 2014 and 2013, our financial position at September 30, 2014 and December 31, 2013, and the cash flows for the nine month periods ended September 30, 2014 and 2013 on a basis consistent with our audited financial statements. These adjustments are of a normal recurring nature and are, in the opinion of management, necessary for fair statement of the financial position and operating results for the interim periods. As used in this Quarterly Report on Form 10-Q, the terms “NN”, “the Company”, “we”, “our”, or “us” mean NN, Inc. and its subsidiaries.
	Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted from the interim financial statements presented in this Quarterly Report on Form 10-Q. These unaudited, condensed and consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our most recent Annual Report on Form 10-K for the year ended December 31, 2013 which we filed with the Securities and Exchange Commission on March 14, 2014. The results for the three and nine month periods ended September 30, 2014 are not necessarily indicative of results for the year ending December 31, 2014 or any other future periods.

Business Combinations [Abstract]	'
Acquisitions	'
	Note 2. Acquisitions
	Autocam
	On August 29, 2014, we completed our merger with Autocam Corporation (“Autocam”), for $256,837 in cash and $31,717 in NN stock. Additionally, we assumed $29,160 in Autocam debt and capital lease obligations. Autocam is a global leader in the engineering, manufacture and assembly of highly complex, system critical components for fuel systems, engines and transmission, power steering and electric motors. With the completion of the transaction, NN becomes one of the top global manufacturers in the precision metal components space. Additionally, this acquisition will leverage NN’s and Autocam’s complementary core strengths and values and will position our Precision Metal Components business segment to outgrow its end markets by taking advantage of global market trends in fuel efficient technologies such as gasoline direct injection systems, high-pressure diesel injection systems and variable valve timing.
	The funding of the cash portion of the purchase price and acquisition costs was provided primarily from borrowings, including a $350,000 term loan entered into concurrent with the acquisition. (See Note 7 of the Notes to Condensed Consolidated Financial Statements).
	The following table summarizes the preliminary purchase price allocation for the Autocam merger:
	Preliminary fair value of assets acquired
	and liabilities assumed on August 29, 2014
	Current assets	$	88,529
	Property, plant, and equipment		146,120
	Intangible assets subject to amortization		51,098
	Investment in joint venture		35,595
	Other non-current assets		2,170
	Goodwill		77,548
	Total assets acquired	$	401,060
	Current liabilities		34,320
	Current maturities of long-term debt		6,547
	Non-current deferred tax liabilities		46,998
	Obligations under capital lease		18,350
	Long-term debt, net of current portion		4,263
	Other non-current assets		2,028
	Total liabilities assumed	$	112,506
	Net asset acquired	$	288,554
	The combination of income, market, and cost approaches were used for the preliminary valuation where appropriate, depending on the asset or liability being valued. Valuation inputs in these models and analyses gave consideration to market participant assumptions. Acquired intangible assets are primarily customer relationships and trade names. The Autocam acquisition occurred late in the third quarter, and NN is still in the process of valuing the assets acquired and liabilities assumed. The allocation of the purchase price is preliminary and subject to change. Accordingly, adjustments may be made to the values of the acquired assets and liabilities assumed as additional information is obtained about the facts and circumstances that existed at the valuation date. The final determination of the purchase price allocation is anticipated to be completed as soon as practicable and most likely by the filing of our 2014 annual report on Form 10-K in March 2015.
	In connection with the purchase, we recorded goodwill, which represents the excess of the purchase price over the estimated preliminary fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to Autocam as a going concern and the fair value of expected cost synergies and revenues growth from combining the NN and Autocam businesses. The going concern element represents the ability to earn a higher return on the combined assembled collection of assets and businesses of Autocam than if those assets and businesses were to be acquired and managed separately. Other relevant elements of goodwill are the benefits of access to certain markets and the assembled work force. None of the goodwill is expected to be deducted for tax purposes.
	Property, plant and equipment acquired primarily included machinery and equipment for use in manufacturing operations. Additionally, a number of manufacturing sites and related facilities, land and leased manufacturing sites that include leasehold improvements were acquired. Property, plant and equipment has been preliminarily valued using the cost approach supported where available by observable market data which includes consideration of obsolescence. Intangible assets have been preliminarily valued using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data.
	Related to the acquisition of Autocam, in the third quarter and first nine months of 2014, we recognized $5,316 and $5,857, respectively, in transaction costs. During the third quarter and the first nine months of 2014, we expensed $2,974 of deferred financing costs and make whole interest payments related to the acquisition. Transaction costs were expensed as incurred and are included in the “Acquisition related costs excluded from selling, general and administrative expenses” line item and deferred financing costs are included in the interest expense line items in the Unaudited Condensed Consolidated Statements of Comprehensive Income. As required by purchase accounting, the acquired inventories were recorded at their preliminary estimated fair value. These inventories were sold in the third quarter 2014 resulting in a one-time $1,992 increase in cost of sales. Beginning September 1, 2014, the consolidated results of operations of NN include the results of the acquired Autocam businesses. Since the date of the acquisition, sales revenue of $21,639 and net income of $1,382 (excluding the non-recurring $1,274 for the one-time increase in cost of goods sold, net of tax) has been included in NN’s financial statements.
	The unaudited pro forma financial results for three months ended September 30, 2014 and September 30, 2013 and nine months ended September 30, 2014 and September 30, 2013 combine the consolidated results of NN and Autocam giving effect to the acquisition of Autocam as if it had been completed on January 1, 2013, the beginning of the comparable prior annual reporting period presented. The unaudited pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2013.
	The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the preliminary fair value step-up and estimated useful lives of Autocam depreciable fixed assets and definite-life amortizable assets acquired in the transaction. The unaudited pro forma results also include adjustments to net interest expense and early debt extinguishment costs related to the transaction. The provision for income taxes has also been adjusted for all periods, based upon the foregoing adjustments to historical results.
		Three Months ended				Nine Months ended
		September 30,				September 30,
		2014		2013		2014			2013
	Pro forma sales	$	166,979	$	152,708	$	505,891		$	457,466
	Pro forma net income	$	4,867	$	5,436	$	19,815		$	(224	)
	The pro forma net income for the nine months ended September 30, 2013 includes certain items, such as financing, integration, and transaction costs historically recorded by NN and Autocam directly attributable to the acquisition, which will not have an ongoing impact. These items include transaction, integration, and financing related costs incurred by NN and Autocam of $8,509 and $8,933, net of tax, and $3,010 and $3,125, net of tax, respectively during third quarter and first nine months of 2014, respectively, and reported in the nine months ended September 30, 2013 pro forma net income above.
	Other Acquisitions
	We made three other acquisitions during the first nine months of 2014 that aggregated to $20,995 in net assets acquired. Related to the acquisitions, we incurred transactions costs of $1,179 from third parties during the nine months ended September 30, 2014, which were expensed as incurred in acquisition related costs excluded from selling, general and administrative within the Condensed Consolidated Statements of Comprehensive Income.
	The accounting for these business combinations is based on currently available information and is considered preliminary. We are in the process of finalizing fair market valuations of all the net assets acquired. The final determination of the purchase price allocation is anticipated to be completed as soon as practicable and most likely by the filing of our 2014 annual report on Form 10-K in March 2015. Any adjustments to such allocations are not expected to have a material impact on our financial position or results of operations.
	The following table summarizes the preliminary fair values of assets acquired and liabilities assumed at the date of acquisition with any adjustments to fair value since June 30, 2014.
	Assets acquired and liabilities assumed	June 30,		Net Assets		2014			September
		2014		acquired		adjustments			30, 2014
				in third		to fair value

	Current assets	$	5,347	$	397	$	(56	)	$	5,688
	Property, plant, and equipment		14,750		274		343			15,367
	Intangible assets subject to amortization		1,815		1,140		(250	)		2,705
	Goodwill		732		1,428		(122	)		2,038
	Total assets acquired	$	22,644	$	3,239	$	(85	)	$	25,798
	Current liabilities	$	4,749	$	139	$	(85	)	$	4,803
	Total liabilities assumed	$	4,749	$	139	$	(85	)	$	4,803
	Net asset acquired	$	17,895	$	3,100	$	—		$	20,995
	The intangible assets subject to amortization are for customer contracts and trade names totaling $2,705 and have weighted average useful lives of approximately 10 years. Goodwill of $2,038 arising from the acquisitions is attributable primarily to the assembled workforce of RFK and strategic market opportunities that are expected to arise from the acquisition of RFK and Chelsea.
	In the following paragraphs we will provide a brief description of the businesses acquired, reasons for the acquisition and relevant financial information about each business.
	Chelsea Grinding (Chelsea)
	On July 15, 2014, we purchased the assets of Chelsea Grinding for $3,100 in cash. Chelsea is a hydraulic component manufacturer. We acquired Chelsea to achieve access to the adjacent hydraulic component market. Chelsea, which has been completely integrated into our Erwin Plant of the Metal Bearing Components Segment, has contributed revenues of approximately $500 from the date of acquisition to September 30, 2014.
	RFK Valjcici d. d. Konjic (“RFK”)
	On June 20, 2014, we acquired 79.2% of the outstanding shares of RFK Valjcici d. d. Konjic (“RFK”) for $9,756 in cash. RFK is a manufacturer of tapered rollers with operations in Konjic, Bosnia & Herzegovina. Its products, while complementary to NN’s existing roller bearing components, will broaden our product offering and allow penetration into adjacent markets. NN acquired up to 99.7% of the shares of RFK during the third quarter of 2014 for an additional $2,528 in cash. RFK has contributed revenues and net income of $2,564 and $88, respectively, from the date of acquisition to September 30, 2014. RFK was a listed company on the Sarajevo Stock Exchange founded in 1984 and is expected to have sales of approximately $12.0 million in 2014. RFK currently exports all of its products, predominately to customers serving the European truck, industrial vehicle and railway markets. NN will continue operations at the existing facilities in Bosnia & Herzegovina and will roll up the operations under our Metal Bearing Components Segment. In addition, we have reported non-controlling interest of $38 for RFK representing the fair value of the 0.30% of the shares outstanding we do not own as of September 30, 2014.
	VS Assets Purchase
	On January 30, 2014, we purchased the majority of the operating assets of V-S Industries, V-S Precision, LLC and V-S Precision SA de DV (collectively referred to as “VS”) from the secured creditors of V-S Industries for $5,580 in cash and assumed certain liabilities totaling $2,968. VS has contributed revenues and net loss of approximately $10,518 and $(957), including the integration costs, respectively, from the date of acquisition to September 30, 2014.
	VS is a precision metal components manufacturer that supplies customers in a variety of industries including electric motors, HVAC, power tools, automotive and medical. The acquisition of VS will provide us with a complementary, but broader product offering and will allow penetration into adjacent markets. VS has two locations in Wheeling, Illinois and Juarez, Mexico and will roll up under the Precision Metal Components Segment.

Net Income Per Share	'
	Note 4. Net Income Per Share
	The difference between the basic weighted average shares outstanding and the diluted weighted average shares outstanding for all periods reported are the effect of dilutive stock options calculated using the treasury stock method. The dilutive shares for the nine month period ended September 30, 2014 were 371. For the three month period ended September 30, 2014, 432 shares of common stock were excluded from the calculation of diluted loss per share because their effect would be antidilutive. The dilutive shares for the three and nine month periods ended September 30, 2013 were 148 and 55, respectively. There were no anti-dilutive options excluded from the dilutive shares outstanding for the three and nine month periods ended September 30, 2014. Excluded from the dilutive shares outstanding for the three and nine month periods ended September 30, 2013 were 1,390 of anti-dilutive options which had exercise prices ranging from $8.54 to $14.13.

	On August 29, 2014, concurrent with the Autocam acquisition, we entered into two new credit facilities consisting of a $350 million term loan facility and a $100 million asset backed revolver (“ABL”). These new facilities were utilized to fund the Autocam acquisition and to provide for short-term cash flow needs. Additionally, these new facilities replaced the $100 million revolving credit facility and the $20 million fixed rate agreement both of which were paid off with proceeds from the term loan. $1,368 in net capitalized loan origination costs related to the $100 million facility was written off as of August 29, 2014. $30 in net capitalized loan origination costs related to the $20 million fixed rate agreements was also written off as of August 29, 2014.
	The $350,000 term loan revolving credit facility may be expanded upon our request with approval of the lenders by up to $50,000 under the same terms and conditions. The term loan has a seven year maturity with a 5% per annum repayment. The term loan agreement is a covenant lite agreement with no financial covenants. The loan agreement does contain 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 give the lenders the right to accelerate the maturity of the debt. Costs associated with entering into the revolving credit facility were capitalized and will be amortized into interest expense over the life of the facility. As of September 30, 2014, $8,243 of net capitalized loan origination costs related to the term loan credit facility were recorded on the condensed consolidated balance sheet within other non-current assets.
	The $100,000 ABL may be expanded upon our request with approval of the lenders by up to $50,000 under the same terms and conditions. The ABL has a five year maturity and has one springing financial covenant in the event our availability on the ABL is less than $8,000. The ABL contains 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 give the lenders the right to accelerate the maturity of the debt. The facility has a swing line feature to meet short term cash flow needs. Any borrowings under this swing line are considered short term. We incurred costs as a result of issuing the ABL which have been recorded on the condensed consolidated balance sheet within other non-current assets and are being amortized over the term of the notes. The unamortized balance at September 30, 2014 was $1,020.
	We believe the book values of the above credit facilities approximate their fair values given the interest rates are variable and we entered into these facilities very close to the quarter ended September 30, 2014, at the then market rates for a company with our credit profile.
	As part of the merger with Autocam, NN assumed certain foreign credit facilities. These facilities relate to local borrowings in France, Brazil and China. These facilities are with financial institutions in the countries in which foreign plants operate and are meant to fund working capital and equipment purchases in those countries. Below is a description of the credit facilities.
	In 2008, Autocam filed “Procedure de Sauvegarde” (“Safeguard”) on behalf of each of their French subsidiaries, Autocam France, SARL and Bouverat Industries, SAS (“Bouverat”). They reached agreement with their creditors with claims subject to Safeguard protection in 2009. Provisions of the agreements allowed, at each creditor’s option, for the payment of a portion of the obligation in January 2010, or the entire obligation over a 10-year period. The liabilities carry a zero percent interest rate and are being paid annually until 2019. Amounts due as of September 30, 2014, to those creditors opting to be paid over a 10-year period totaled $2,935 and are included in Current Maturities of Long-Term debt ($259) and long-term debt excluding current maturities of long-term debt ($2,676).
	The Brazilian lines of credit include facilities with certain Brazilian banks to funding working capital and equipment purchases for the Brazilian plants of Autocam. The lines of credit have interest rates of 2.5% to 13.3%. The Chinese line of credit is a working capital line of credit with a Chinese bank with an interest rate of 4.95%.

During the nine month period ended September 30, 2014, there were 98 share awards and 98 options awards to non-executive directors, officers and certain other key employees. During the nine month period ended September 30, 2013, there were 95 share awards and 354 options awards to non-executive directors, officers and certain other key employees.
	The restricted shares granted during the nine month periods ended September 30, 2014 and 2013, vest pro-rata over three years. During the nine month periods ended September 30, 2014 and 2013, we incurred $951 and $606, respectively, in expense related to restricted stock. The fair value of the shares issued was determined by using the grant date closing price of our common stock.
	We incurred $997 and $1,060 of stock option expense in the nine month periods ended September 30, 2014 and 2013, respectively. The fair value of our options cannot be determined by market value, as our options are not traded in an open market. Accordingly, the Black Scholes financial pricing model is utilized to estimate the fair value.
	The following table provides a reconciliation of option activity for the nine month period ended September 30, 2014:
	Options		Shares (000)			Weighted-		Weighted-		Aggregate
						Average		Average		Intrinsic Value

	Note 12. Provision for Income Taxes
	For the nine month periods ended September 30, 2014 and 2013, our effective tax rates were 40% and 34%, respectively. The difference between the U.S. federal statutory tax rate of 34% and our effective tax rate was due to the impact of non-deductible merger and acquisition expenses increasing the tax rate 12% during 2014. The non-deductible merger costs were partially offset by non-U.S. based earnings being taxed at lower rates reducing the effective rate 6%.
	As of September 30, 2014, we do not foresee any significant changes to our unrecognized tax benefits within the next twelve months.

	All legal proceedings, with the exception of the bankruptcy of our German subsidiary discussed below, 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 $0 and $200 at September 30, 2014 and December 31, 2013, respectively, which we believe are adequate to cover all probable liabilities to be incurred by all of the cases in the aggregate.
	As discussed more fully in our Annual Report on Form 10-K filed March 14, 2014, the ultimate impact on NN of our wholly owned German subsidiary Kugelfertigung Eltmann GbmH (“Eltmann” or “Eltmann Plant”) filing for bankruptcy will depend on the findings of the bankruptcy court. We do not expect any further significant impacts on our condensed consolidated financial statements as a result of the liquidation of this subsidiary.
