Interim Financial Statements

Quarterly Financial Information Disclosure [Abstract]
Interim Financial Statements	Interim Financial Statements Nature of Business NN, Inc. is a global diversified industrial company that combines advanced engineering and production capabilities with in-depth materials science expertise to design and manufacture high-precision components and assemblies for the medical, aerospace and defense, electrical, automotive, and general industrial markets. As used in this Quarterly Report on Form 10-Q (this “Quarterly Report), the terms “NN,” the “Company,” “we,” “our,” or “us” refer to NN, Inc., and its subsidiaries. Basis of Presentation In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40) , the Company has evaluated whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date of the issuance of these unaudited interim financial statements. The Company’s existing revolving line of credit, which has a maximum capacity of $110.0 million , matures on October 19, 2020 (the “Senior Secured Revolver”). The Company leverages such line of credit, along with cash generated from operations, to fund operations and working capital and had $71.5 million of outstanding borrowings as of November 6, 2019 . Based on our current and projected use of the facility, as well as cash flows to be generated from operations and investing activities, we do not anticipate that we will be able to repay the outstanding borrowings when they become due in October 2020 without refinancing the line of credit or obtaining new financing. The Company has and continues to make efforts to obtain new financing; however, there is no assurance that we will obtain sufficient financing on commercially reasonable terms, if at all, before the outstanding amounts would be required to be repaid. This condition raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date of issuance of these financial statements. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. The accompanying condensed consolidated financial statements have not been audited, except that the Condensed Consolidated Balance Sheet as of December 31, 2018 , was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 (the “ 2018 Annual Report”), which we filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 18, 2019 . In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to fairly state our results of operations for the three and nine months ended September 30, 2019 and 2018 ; financial position as of September 30, 2019 , and December 31, 2018 ; and cash flows for the nine months ended September 30, 2019 and 2018 , on a basis consistent with our audited consolidated financial statements other than the adoption of new accounting standards, such as the new lease standard (see Note 10 ). These adjustments are of a normal recurring nature and are, in the opinion of management, necessary to state fairly the Company’s financial position and operating results for the interim periods. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted from the interim financial statements presented in this Quarterly Report. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the 2018 Annual Report. The results for the three and nine months ended September 30, 2019 , are not necessarily indicative of results for the year ending December 31, 2019 , or any other future periods. Except for per share data or as otherwise indicated, all U.S. dollar amounts presented in the tables in these Notes to Condensed Consolidated Financial Statements are in thousands. Prior Periods’ Financial Statement Revisions In connection with the preparation of our interim financial statements for the nine months ended September 30, 2019 , we identified tax accounting misstatements in our previously issued 2018 Annual Report. Such misstatements relate to the tax accounting associated with the 2018 impairment of our joint venture as well as other immaterial tax misstatements. We assessed the materiality of the misstatements on prior periods’ financial statements in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 1.M, Materiality , codified in Accounting Standards Codification (“ASC”) Topic 250, Accounting Changes and Error Corrections , (“ASC 250”) and concluded that the misstatements were not material to the prior annual or interim periods. However, the Company has determined that it will revise its previously issued 2018 and 2017 annual financial statements, and relevant interim periods, to correct for these misstatements. In connection with such revision, the Company will correct for an immaterial tax misstatement that originated in 2017 and had been previously corrected for as an out of period adjustment in 2018. In connection with the filing of this Quarterly Report, we have revised the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss) and our Consolidated Statements of Cash Flows for the nine months ended September 30, 2018 , and have reflected the impact of the revision on our Consolidated Balance Sheet as of December 31, 2018 . Refer to Note 17 for the effect of the correction of the misstatements on each of the financial statements noted above. Accounting Standards Recently Adopted Leases. On January 1, 2019 , we adopted Accounting Standards Codification (“ASC”) 842, Leases , which superseded ASC 840, Leases . We adopted ASC 842 utilizing the modified retrospective transition approach; therefore, historical financial information and disclosures do not reflect the new standard and will continue to be presented under the previous lease accounting guidance. Under the modified retrospective transition method, the cumulative effect of the initial adoption adjustment of less than $0.1 million was recognized to the opening balance of retained deficit as of January 1, 2019 . As part of the adoption, we elected the package of practical expedients, the short-term lease exemption, and the practical expedient to not separate lease and non-lease components. We recorded lease-related assets and liabilities to our balance sheet for leases with terms greater than twelve months that were classified as operating leases and not previously recorded on our balance sheet. See Note 10 for the required disclosures related to ASC 842. Derivatives and Hedging . In August 2017 , the Financial Accounting Standards Board (“FASB”) issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , (“ASU 2017-12”). ASU 2017-12 provides new rules that expand the hedging strategies that qualify for hedge accounting. The new rules also allow additional time to complete hedge effectiveness testing and allow qualitative assessments subsequent to initial quantitative tests if there is a supportable expectation that the hedge will remain highly effective. We adopted the guidance on January 1, 2019 . We have applied the new rules to 2019 hedging activities as disclosed in Note 16 to these condensed consolidated financial statements. The new guidance has no effect on our historical financial statements. Effects of Tax Reform in Other Comprehensive Income. In February 2018 , the FASB issued guidance related to the impacts of the U.S. Tax Cuts and Jobs Act of 2017 (“Tax Act”). Under existing U.S. GAAP, the effects of changes in tax rates and laws on deferred tax balances are recorded as a component of income tax expense in the period in which the law was enacted. When deferred tax balances related to items originally recorded in accumulated other comprehensive income (“AOCI”) are adjusted, certain tax effects become stranded in AOCI. The FASB issued ASU 2018-2, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, that permits reclassification of certain income tax effects of the Tax Act from AOCI to retained earnings. The guidance also requires certain disclosures about stranded tax effects. The new guidance was effective for us on January 1, 2019 . We adopted the new guidance at the beginning of the period of adoption. The new guidance had no effect on our financial statements. Accounting Standards Not Yet Adopted Fair Value Disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) , that modifies fair value disclosure requirements. The new guidance could impact us by streamlining disclosures of Level 3 fair value measurements. The modified disclosures are effective for us beginning in the first quarter of 2020 , with early adoption allowed. ASU 2018-13 changes disclosures only and does not impact our financial condition, results of operations, or cash flows. We are in the process of evaluating the effects of this guidance on our fair value disclosures. Internal-Use Software. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) (“ASU 2018-15”) , that provides guidance on a customer’s accounting for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor. Under the new guidance, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. ASU 2018-15 is effective for us on January 1, 2020 , using either a prospective or retrospective approach and with early adoption permitted. We are in the process of evaluating the effects of this guidance on our financial statements, but do not expect the adoption to have a material impact. Financial Instruments - Credit Losses . In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which modifies the measurement of expected credit losses on certain financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for us on January 1, 2020 , using a modified retrospective approach, with early adoption permitted. We are in the process of evaluating the effects of this guidance on our financial statements, but do not expect the adoption to have a material impact.

Business Combinations [Abstract]
Acquisitions	Acquisitions Paragon Medical, Inc. On May 7, 2018 , we acquired 100% of the stock of PMG Intermediate Holding Corporation, the parent company of Paragon Medical, Inc.

Goodwill	Goodwill The following table shows changes in the carrying amount of goodwill by reportable segment. Life Sciences Power Solutions Total Balance as of December 31, 2018 $ 344,947 $ 94,505 $ 439,452 Currency impacts/Other (1,970 ) (202 ) (2,172 ) Balance as of September 30, 2019 $ 342,977 $ 94,303 $ 437,280 In 2018 , Mobile Solutions recorded an impairment loss on goodwill. As of September 30, 2019 , no goodwill was recorded at Mobile Solutions. Based on the closing price of a share of our common stock as of September 30, 2019 , our market capitalization was at a level that is less than the net book value of our stockholders’ equity. A prolonged or significant decline in market capitalization could be an indicator of additional goodwill impairment. We concluded that our market capitalization as of September 30, 2019, was not at a level that would require us to perform a goodwill impairment assessment during the period. We will continue to monitor our market capitalization to determine if an indicator of impairment exists in subsequent periods. During 2018 , as a result of our annual goodwill impairment analysis performed during the fourth quarter of 2018 , we recorded an impairment of $109.1 million in our Power Solutions group. Subsequent to the impairment, at December 31, 2018 , Power Solutions reported a goodwill balance of $94.5 million . Given the carrying value of the Power Solutions group was equal to its fair value at December 31, 2018 , as a result of the 2018 goodwill impairment, if actual performance of the Power Solutions group falls short of expected results, additional material impairment charges may be required. During the third quarter of 2019 , we assessed for triggering events that would signify the need to perform an impairment test and concluded there were no triggering events during the period. Our annual impairment analysis will be completed as of October 1, 2019.

Equity Method Investments and Joint Ventures [Abstract]
Investment in Joint Venture	Investment in Joint Venture We own a 49% investment in Wuxi Weifu Autocam Precision Machinery Company, Ltd. (the “JV”), a joint venture located in Wuxi, China. The JV is jointly controlled and managed, and we account for it under the equity method. The following table shows changes in our investment in the JV. Balance as of December 31, 2018 $ 20,364 Share of earnings 345 Foreign currency translation loss (832 ) Balance as of September 30, 2019 $ 19,877 During the fourth quarter of 2018 , as a result of changing market conditions, the fair value of the JV was assessed and we recorded an impairment of $16.6 million against our investment in the JV. The fair value assessment was significantly affected by changes in our assessment of future growth rates. It is reasonably possible that material deviation of future performance from the estimates used in the 2018 valuation could result in additional impairment to our investment in the JV in subsequent periods. During the third quarter of 2019 , we assessed for triggering events that would signify the need to perform an impairment test and concluded there were no triggering events during the period. We recognized sales to the JV of less than $0.1 million and $0.1 million during the three and nine months ended September 30, 2019 , respectively, and less than $0.1 million and $0.2 million for the three and nine months ended September 30, 2018 , respectively.

Income Taxes	Income Taxes Our effective tax rate was 17.9% and (5.2)% for the three months and nine months ended September 30, 2019 , respectively. Our effective tax rate was 28.4% and 20.8% for the three months and nine months ended September 30, 2018 , respectively. Our effective tax rate for the nine months ended September 30, 2019 , differs from the U.S. federal statutory tax rate of 21% principally due to a discrete tax charge of $6.0 million related to final tax regulations published by the Department of the Treasury and Internal Revenue Service on February 4, 2019 , as well as the minimum tax on global intangible low-tax income (“GILTI”). The effective tax rate for the three months ended September 30, 2019 , is impacted by the minimum tax on GILTI. Our 2018 effective tax rate differed from the U.S. federal statutory tax rate of 21% due to permanent differences including GILTI and earnings outside the United States, which were taxed at different rates than the U.S. federal statutory rate of 21% .

The credit facility is collateralized by all of our assets. The following table presents debt balances as of September 30, 2019 , and December 31, 2018 . September 30, 2019 December 31, 2018 Senior Secured Term Loan $ 527,750 $ 532,063 Incremental Term Loan 270,000 279,000 Senior Secured Revolver 71,323 38,720 International lines of credit and other loans 9,897 9,810 Total principal 878,970 859,593 Less — current maturities of long-term debt 25,601 31,280 Principal, net of current portion 853,369 828,313 Less — unamortized debt issuance costs 11,621 16,842 Long-term debt, net of current portion $ 841,748 $ 811,471 We capitalized interest costs of $0.4 million and $0.3 million in the three months ended September 30, 2019 and 2018 , respectively, and $1.5 million and $0.8 million in the nine months ended September 30, 2019 and 2018 , respectively, related to construction in progress. Senior Secured Term Loan Outstanding borrowings under the Senior Secured Term Loan bear interest at the greater of 0.75% or one-month London Interbank Offered Rate (“LIBOR”) plus an applicable margin of 3.75% . At September 30, 2019 , the Senior Secured Term Loan bore interest at 5.80% . Incremental Term Loan Outstanding borrowings under the Incremental Term Loan bear interest at one-month LIBOR plus an applicable margin of 3.25% . At September 30, 2019 , the Incremental Term Loan bore interest of 5.30% .

At September 30, 2019 , the weighted average interest rate on outstanding borrowings under the Senior Secured Revolver was 5.73% . We pay a commitment fee of 0.50% for unused capacity under the Senior Secured Revolver. In March 2019 , we amended our existing credit facility (the “March 2019 amendment”) to amend the defined terms within the credit facility. In June 2019, we amended our existing credit facility (the “June 2019 amendment”) to reduce the maximum capacity under the Senior Secured Revolver to $110.0 million , reduce the total available capacity to $100.0 million , and modify the consolidated net leverage ratio, as defined in the credit facility agreement, which is utilized for certain financial covenants. We paid $0.8 million and $0.2 million of debt issuance costs related to the March 2019 amendment and June 2019 amendment , respectively, which were recorded as a direct reduction to the carrying amount of the associated long-term debt. Additionally, $2.7 million of unamortized debt issuance costs associated with the March 2019 amendment to the existing credit facility were written off. We had $71.3 million outstanding under the Senior Secured Revolver at September 30, 2019 . Total available capacity under the Senior Secured Revolver was $100.0 million as of September 30, 2019 , with $16.7 million available for future borrowings after reductions for outstanding letters of credit and outstanding borrowings as of September 30, 2019 . Our credit facility is subject to certain financial covenants based on a consolidated net leverage ratio. The financial covenants are effective when we have outstanding borrowings under our Senior Secured Revolver on the last day of any fiscal quarter, become more restrictive over time, and are dependent upon our operational and financial performance. If our operational or financial performance does not improve in line with our expectations, we may be required to take actions to reduce expenditures and decrease our net indebtedness to maintain compliance in future periods. We were in compliance with all covenants under our credit facility at September 30, 2019 . As discussed in Note 1 , the outstanding amounts under our Senior Secured Revolver are recognized as a current liability as of October 20, 2019 . Derivative Instruments and Hedging Activities In February 2019 , we entered into a $700.0 million amortizing notional amount fixed-rate interest rate swap agreement to manage the interest rate risk associated with our long-term variable-rate debt until 2022. The fixed-rate interest rate swap agreement calls for us to receive interest monthly at a variable rate equal to one-month LIBOR and to pay interest monthly at a fixed rate of 2.4575% . Refer to Note 16 for further discussion of the interest rate swap agreement.

Leases [Abstract]
Leases	Leases We adopted ASC 842 on January 1, 2019 , and elected the modified retrospective approach in which the new standard is applied to all leases existing at the date of adoption through a cumulative-effect adjustment of less than $0.1 million to retained deficit. Consequently, financial information is not updated, and the disclosures required under the new standard are not provided for periods prior to January 1, 2019 . As part of the adoption, we elected the package of practical expedients, the short-term lease exemption, and the practical expedient to not separate lease and non-lease components. Accordingly, we accounted for our existing operating leases as operating leases under the new standard, without reassessing (a) whether the contracts contain a lease under ASC 842, (b) whether classification of the operating leases would be different in accordance with ASC 842, or (c) whether any unamortized initial direct costs would have met the definition of initial direct costs in ASC 842 at lease commencement. We determine whether an arrangement is a lease at inception. Right-of-use (“ROU”) lease assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. When the implicit rate is not readily determinable, we use the estimated incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Amortization of ROU lease assets is recognized in expense on a straight-line basis over the lease term. Short-term leases are leases having a term of twelve months or less. We recognize short-term leases on a straight-line basis and do not record a related lease asset or liability for such leases. Finance lease ROU assets consist of equipment used in the manufacturing process with terms greater than twelve months to seven years . Operating lease ROU assets consist of the following: • Equipment used in the manufacturing process as well as office equipment with terms greater than twelve months to seven years ; and • Manufacturing plants and office facilities with terms greater than twelve months to 25 years .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Brazil ICMS Tax Matter Prior to the acquisition of Autocam Corporation in 2014 (“Autocam”), Autocam’s Brazilian subsidiary (“Autocam Brazil”) received notification from the Brazilian tax authority regarding ICMS (state value added tax or “VAT”) tax credits claimed on intermediary materials (e.g., tooling and perishable items) used in the manufacturing process. The Brazilian tax authority notification disallowed state ICMS tax credits claimed on intermediary materials based on the argument that these items are not intrinsically related to the manufacturing processes. Autocam Brazil filed an administrative defense with the Brazilian tax authority arguing, among other matters, that it should qualify for an ICMS tax credit, contending that the intermediary materials are directly related to the manufacturing process. We believe that we have substantial legal and factual defenses, and we plan to defend our interests in this matter vigorously. The matter encompasses several lawsuits filed with the Brazilian courts requesting declaratory actions that no tax is due or seeking a stay of execution on the collection of the tax. In 2018, we obtained a favorable decision in one of the declaratory actions for which the period for appeal has expired. We have filed actions in each court requesting dismissal of the matter based on the earlier court action. Although we anticipate a favorable resolution to all matters, we can provide no assurances that we will be successful in achieving dismissal of all pending cases. While we believe a loss is not probable, we estimate the range of possible losses related to this assessment is from $0 to $6.0 million . No amount was accrued at September 30, 2019 , for this matter. We are entitled to indemnification from the former shareholders of Autocam, subject to the limitations and procedures set forth in the agreement and plan of merger relating to the Autocam acquisition. Management believes the indemnification would include amounts owed for the tax, interest, and penalties related to this matter. Securities Offering Matter On November 1, 2019, Erie County Employees’ Retirement System, on behalf of a purported class of plaintiffs, filed a complaint in the Supreme Court of the State of New York, County of New York, against the Company, certain of the Company’s current and former officers and directors, and each of the underwriters involved in the Company’s public offering and sale of 14,375,000 shares of its common stock pursuant to a preliminary prospectus supplement, dated September 10, 2018, a final prospectus supplement, dated September 13, 2018, and a base prospectus, dated April 19, 2017, relating to the Company’s effective shelf registration statement on Form S-3 (File No. 333-216737) (the “Offering”). The complaint alleges violations of Sections 11, 12(a)(2), and 15 of the Securities Act of 1933 in connection with the Offering. The plaintiffs seek to represent a class of stockholders who purchased shares of the Company’s common stock in the Offering. The complaint seeks unspecified monetary damages and other relief. The Company believes the complaint and allegations to be without merit and intends to vigorously defend itself against these actions. The Company is unable at this time to determine whether the outcome of the litigation would have a material impact on the Company’s financial position, results of operations, or cash flows. All Other Legal Matters All other 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.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenue is recognized when control of the good or service is transferred to the customer either at a point in time or, in limited circumstances, as our services are rendered over time. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or services. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. The following tables present sales to external customers by reportable segment.

Shared-Based Compensation	Share-Based Compensation The following table lists the components of share-based compensation expense by type of award. Three Months Ended Nine Months Ended 2019 2018 2019 2018 Stock options $ 371 $ 173 $ 732 $ 531 Restricted stock 446 388 1,407 1,244 Performance share units 334 530 991 1,650 Change in estimate of share-based award vesting (1,275 ) (802 ) (1,275 ) (802 ) Share-based compensation expense $ (124 ) $ 289 $ 1,855 $ 2,623 Stock Options During the nine months ended September 30, 2019 , we granted options to purchase 210,400 shares to certain key employees. The weighted average grant date fair value of the options granted during the nine months ended September 30, 2019 , was $2.77 per share. The fair value of our options cannot be determined by market value because they are not traded in an open market. Accordingly, we utilized the Black Scholes financial pricing model to estimate the fair value. The following table shows the weighted average assumptions relevant to determining the fair value of stock options granted in 2019 . 2019 Expected term 6 years Risk free interest rate 2.47 % Dividend yield 3.53 % Expected volatility 49.53 % Expected forfeiture rate 4.00 % The expected term is derived from using the simplified method of determining stock option terms as described under the Staff Accounting Bulletin Topic 14, Share-based payment . The simplified method was used because sufficient historical stock option exercise experience was not available, primarily due to the transformation of the management structure over the past several years. 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 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 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 a mathematical formula utilizing daily closing price data. The forfeiture rate is determined from examining the historical pre-vesting forfeiture patterns of past option issuances to key employees. 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 following table presents stock option activity for the nine months ended September 30, 2019 . Number of Options (in thousands) Weighted- Average Exercise Price (per share) Weighted- Average Remaining Contractual Term (years) Aggregate Intrinsic Value Outstanding at January 1, 2019 771 $ 15.17 Granted 210 7.93 Exercised (5 ) 4.42 $ 7 Forfeited or expired (139 ) 15.61 Outstanding at September 30, 2019 837 $ 13.34 6.0 $ — (1) Exercisable at September 30, 2019 570 $ 14.24 4.6 $ — (1) _______________________________ (1) The aggregate intrinsic value is the sum of intrinsic values for each exercisable individual option grant. The intrinsic value is the amount by which the closing market price of our stock at September 30, 2019 , was greater than the exercise price of any individual option grant. Restricted Stock During the nine months ended September 30, 2019 , we granted 309,234 restricted stock awards to non-executive directors, officers and certain other key employees. The shares of restricted stock granted during the nine months ended September 30, 2019 , vest pro-rata over three years for officers and certain other key employees and over one year for non-executive directors. We determined the fair value of the shares awarded by using the closing price of our common stock as of the date of grant. The weighted average grant date value of restricted stock granted in the nine months ended September 30, 2019 , was $7.85 per share. Total grant-date fair value of restricted stock that vested in the nine months ended September 30, 2019 , was $2.6 million . The following table presents the status of unvested restricted stock awards as of September 30, 2019 , and changes during the nine months then ended. Nonvested Restricted Shares (in thousands) Weighted Average Grant-Date Fair Value (per share) Nonvested at January 1, 2019 146 $ 22.07 Granted 309 7.85 Vested (144 ) 18.14 Forfeited (79 ) 10.09 Nonvested at September 30, 2019 232 $ 9.62 Performance Share Units Performance Share Units (“PSUs”) are a form of long-term incentive compensation awarded to executive officers and certain other key employees designed to directly align the interests of employees to the interests of our stockholders, and to create long-term stockholder value. PSUs granted in 2019 were made pursuant to the NN, Inc. 2016 Omnibus Incentive Plan and a Performance Share Unit Agreement (the “2016 Omnibus Agreement”). Some PSUs are based on total shareholder return (“TSR Awards”), and other PSUs are based on return on invested capital (“ROIC Awards”). The TSR Awards vest, if at all, upon our achieving a specified relative total shareholder return, which will be measured against the total shareholder return of the S&P SmallCap 600 Index during specified performance periods as defined in the 2016 Omnibus Agreement. The ROIC Awards vest, if at all, upon our achieving a specified average return on invested capital during the performance periods. Each performance period generally begins on January 1 of the year of grant and ends 36 months later on December 31. We recognize compensation expense over the performance period in which the performance and market conditions are measured. If the PSUs do not vest at the end of the performance periods, then the PSUs will expire automatically. Upon vesting, the PSUs will be settled by the issuance of shares of our common stock, subject to the award recipient’s continued employment. The actual number of shares of common stock to be issued to each award recipient at the end of the performance periods will be interpolated between a threshold and maximum payout amount based on actual performance results. No dividends will be paid on outstanding PSUs during the performance period; however, dividend equivalents will be paid based on the number of shares of common stock that are ultimately earned at the end of the performance periods. With respect to the TSR Awards, a participant will earn 50% of the target number of PSUs for “Threshold Performance,” 100% of the target number of PSUs for “Target Performance,” and 150% of the target number of PSUs for “Maximum Performance.” With respect to the ROIC Awards, a participant will earn 35% of the target number of PSUs for “Threshold Performance,” 100% of the target number of PSUs for “Target Performance,” and 150% of the target number of PSUs for “Maximum Performance. For performance levels falling between the values shown below, the percentages will be determined by interpolation. The following table presents the goals with respect to TSR Awards and ROIC Awards granted in 2019 . TSR Awards: Threshold Performance Target Performance Maximum Performance 2019 grants 35th Percentile 50th Percentile 75th Percentile ROIC Awards: Threshold Performance Target Performance Maximum Performance 2019 grants (1) 4.7 % 5.8 % 7.0 % (1) For the ROIC Awards granted in 2019, the denominator of the calculation is different than in prior years, and therefore the target percentages are not comparable to historical target percentages. We estimate the grant date fair value of TSR Awards using the Monte Carlo simulation model, as the total shareholder return metric is considered a market condition under ASC Topic 718, Compensation – stock compensation . The grant date fair value of ROIC Awards is based on the closing price of a share of our common stock on the date of grant. The following table presents the number of PSUs granted and the grant date fair value in the period presented. TSR Awards ROIC Awards Award Year Shares (in thousands) Grant Date Fair Value (per share) Shares (in thousands) Grant Date Fair Value (per share) 2019 136 $ 9.28 174 $ 7.93 We recognize expense for ROIC Awards based on the probable outcome of the associated performance condition. We generally recognize an expense for ROIC Awards based on the Target Performance threshold of 100% because, at the date of grant, the Target Performance is the probable level of performance achievement.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is an exit price representing the expected amount that an entity would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date. We followed consistent methods and assumptions to estimate fair values as more fully described in the 2018 Annual Report. 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. Our financial instruments that are subject to fair value disclosure consist of cash and cash equivalents, accounts receivable, accounts payable, derivatives, and long-term debt. As of September 30, 2019 , the carrying values of these financial instruments approximated fair value. The fair value of floating-rate debt approximates the carrying amount as interest rates are based on short-term maturities. Derivative Financial Instruments We manage our exposure to fluctuations in interest rates using a mix of fixed and variable rate debt. On February 8, 2019 , we entered into a $700.0 million fixed-rate interest rate swap agreement that changed the LIBOR-based portion of the interest rate on a portion of our variable rate debt to a fixed rate of 2.4575% (the “interest rate swap”). The term of the interest rate swap is from the effective date of February 12, 2019 , through the termination date of October 19, 2022 (the “interest rate swap term”). The interest rate swap effectively mitigates our exposures to the risks and variability of changes in LIBOR. The notional amount of the interest rate swap will decrease over the interest rate swap term as follows: Notional Amount February 12, 2019 - December 30, 2020 $ 700,000 December 31, 2020 - December 30, 2021 466,667 December 31, 2021 - October 19, 2022 233,333 The objective of the interest rate swap is to eliminate the variability of cash flows in interest payments on the first $700.0 million of variable rate debt attributable to changes in benchmark one-month LIBOR interest rates. The hedged risk is the interest rate risk exposure to changes in interest payments, attributable to changes in benchmark one-month LIBOR interest rates over the interest rate swap term. If one-month LIBOR is greater than the minimum percentage under the Senior Secured Term Loan, the changes in cash flows of the interest rate swap are expected to exactly offset changes in cash flows of the variable rate debt. The interest rate swap is designated as a cash flow hedge. As of September 30, 2019 , we reported a $12.0 million loss , net of tax, in accumulated other comprehensive income related to the interest rate swap. The following shows the liabilities measured at fair value on a recurring basis for the interest rate swap as of September 30, 2019 . Fair Value Measurements as of September 30, 2019 Description Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Derivative liability - other current liabilities $ — $ 5,719 $ — Derivative liability - other non-current liabilities — 9,514 — Total $ — $ 15,233 $ — The inputs for determining fair value of the interest rate swap are classified as Level 2 inputs. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs which are derived from or corroborated by observable market data such as interest rate yield curves, index forward curves, discount curves, and volatility surfaces. Counterparty to this derivative contract is a highly rated financial institution which we believe carries only a minimal risk of nonperformance. As of December 31, 2018 , we had no interest rate swap agreements or other derivative financial instruments outstanding. Fixed Rate Debt The fair value of our outstanding fixed-rate debt included in the “International lines of credit and other loans” line item within Note 9 to these Notes to Condensed Consolidated Financial Statements was $11.3 million and $10.4 million as of September 30, 2019 and December 31, 2018 , respectively. These fair values represent Level 2 under the three-tier hierarchy described above. The book value of our outstanding fixed-rate debt included in the “International lines of credit and other loans” line item within Note 9 to these Notes to Condensed Consolidated Financial Statements was $9.9 million and $9.8 million as of September 30, 2019 and December 31, 2018 , respectively.

Quarterly Financial Information Disclosure [Abstract]
Nature of Business	Nature of Business NN, Inc. is a global diversified industrial company that combines advanced engineering and production capabilities with in-depth materials science expertise to design and manufacture high-precision components and assemblies for the medical, aerospace and defense, electrical, automotive, and general industrial markets. As used in this Quarterly Report on Form 10-Q (this “Quarterly Report), the terms “NN,” the “Company,” “we,” “our,” or “us” refer to NN, Inc., and its subsidiaries.
Basis of Presentation	Basis of Presentation In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40) , the Company has evaluated whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date of the issuance of these unaudited interim financial statements. The Company’s existing revolving line of credit, which has a maximum capacity of $110.0 million , matures on October 19, 2020 (the “Senior Secured Revolver”). The Company leverages such line of credit, along with cash generated from operations, to fund operations and working capital and had $71.5 million of outstanding borrowings as of November 6, 2019 . Based on our current and projected use of the facility, as well as cash flows to be generated from operations and investing activities, we do not anticipate that we will be able to repay the outstanding borrowings when they become due in October 2020 without refinancing the line of credit or obtaining new financing. The Company has and continues to make efforts to obtain new financing; however, there is no assurance that we will obtain sufficient financing on commercially reasonable terms, if at all, before the outstanding amounts would be required to be repaid. This condition raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date of issuance of these financial statements. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments that might result from the outcome of this uncertainty. The accompanying condensed consolidated financial statements have not been audited, except that the Condensed Consolidated Balance Sheet as of December 31, 2018 , was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 (the “ 2018 Annual Report”), which we filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 18, 2019 . In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to fairly state our results of operations for the three and nine months ended September 30, 2019 and 2018 ; financial position as of September 30, 2019 , and December 31, 2018 ; and cash flows for the nine months ended September 30, 2019 and 2018 , on a basis consistent with our audited consolidated financial statements other than the adoption of new accounting standards, such as the new lease standard (see Note 10 ). These adjustments are of a normal recurring nature and are, in the opinion of management, necessary to state fairly the Company’s financial position and operating results for the interim periods. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted from the interim financial statements presented in this Quarterly Report. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes included in the 2018 Annual Report. The results for the three and nine months ended September 30, 2019 , are not necessarily indicative of results for the year ending December 31, 2019 , or any other future periods. Except for per share data or as otherwise indicated, all U.S. dollar amounts presented in the tables in these Notes to Condensed Consolidated Financial Statements are in thousands.
Prior Periods' Financial Statement Revisions	Prior Periods’ Financial Statement Revisions In connection with the preparation of our interim financial statements for the nine months ended September 30, 2019 , we identified tax accounting misstatements in our previously issued 2018 Annual Report. Such misstatements relate to the tax accounting associated with the 2018 impairment of our joint venture as well as other immaterial tax misstatements. We assessed the materiality of the misstatements on prior periods’ financial statements in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 1.M, Materiality , codified in Accounting Standards Codification (“ASC”) Topic 250, Accounting Changes and Error Corrections , (“ASC 250”) and concluded that the misstatements were not material to the prior annual or interim periods. However, the Company has determined that it will revise its previously issued 2018 and 2017 annual financial statements, and relevant interim periods, to correct for these misstatements. In connection with such revision, the Company will correct for an immaterial tax misstatement that originated in 2017 and had been previously corrected for as an out of period adjustment in 2018. In connection with the filing of this Quarterly Report, we have revised the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss) and our Consolidated Statements of Cash Flows for the nine months ended September 30, 2018 , and have reflected the impact of the revision on our Consolidated Balance Sheet as of December 31, 2018 . Refer to Note 17 for the effect of the correction of the misstatements on each of the financial statements noted above.
Accounting Standards	Accounting Standards Recently Adopted Leases. On January 1, 2019 , we adopted Accounting Standards Codification (“ASC”) 842, Leases , which superseded ASC 840, Leases . We adopted ASC 842 utilizing the modified retrospective transition approach; therefore, historical financial information and disclosures do not reflect the new standard and will continue to be presented under the previous lease accounting guidance. Under the modified retrospective transition method, the cumulative effect of the initial adoption adjustment of less than $0.1 million was recognized to the opening balance of retained deficit as of January 1, 2019 . As part of the adoption, we elected the package of practical expedients, the short-term lease exemption, and the practical expedient to not separate lease and non-lease components. We recorded lease-related assets and liabilities to our balance sheet for leases with terms greater than twelve months that were classified as operating leases and not previously recorded on our balance sheet. See Note 10 for the required disclosures related to ASC 842. Derivatives and Hedging . In August 2017 , the Financial Accounting Standards Board (“FASB”) issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , (“ASU 2017-12”). ASU 2017-12 provides new rules that expand the hedging strategies that qualify for hedge accounting. The new rules also allow additional time to complete hedge effectiveness testing and allow qualitative assessments subsequent to initial quantitative tests if there is a supportable expectation that the hedge will remain highly effective. We adopted the guidance on January 1, 2019 . We have applied the new rules to 2019 hedging activities as disclosed in Note 16 to these condensed consolidated financial statements. The new guidance has no effect on our historical financial statements. Effects of Tax Reform in Other Comprehensive Income. In February 2018 , the FASB issued guidance related to the impacts of the U.S. Tax Cuts and Jobs Act of 2017 (“Tax Act”). Under existing U.S. GAAP, the effects of changes in tax rates and laws on deferred tax balances are recorded as a component of income tax expense in the period in which the law was enacted. When deferred tax balances related to items originally recorded in accumulated other comprehensive income (“AOCI”) are adjusted, certain tax effects become stranded in AOCI. The FASB issued ASU 2018-2, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, that permits reclassification of certain income tax effects of the Tax Act from AOCI to retained earnings. The guidance also requires certain disclosures about stranded tax effects. The new guidance was effective for us on January 1, 2019 . We adopted the new guidance at the beginning of the period of adoption. The new guidance had no effect on our financial statements. Accounting Standards Not Yet Adopted Fair Value Disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) , that modifies fair value disclosure requirements. The new guidance could impact us by streamlining disclosures of Level 3 fair value measurements. The modified disclosures are effective for us beginning in the first quarter of 2020 , with early adoption allowed. ASU 2018-13 changes disclosures only and does not impact our financial condition, results of operations, or cash flows. We are in the process of evaluating the effects of this guidance on our fair value disclosures. Internal-Use Software. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) (“ASU 2018-15”) , that provides guidance on a customer’s accounting for implementation, set-up, and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor. Under the new guidance, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. ASU 2018-15 is effective for us on January 1, 2020 , using either a prospective or retrospective approach and with early adoption permitted. We are in the process of evaluating the effects of this guidance on our financial statements, but do not expect the adoption to have a material impact. Financial Instruments - Credit Losses . In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which modifies the measurement of expected credit losses on certain financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for us on January 1, 2020 , using a modified retrospective approach, with early adoption permitted. We are in the process of evaluating the effects of this guidance on our financial statements, but do not expect the adoption to have a material impact.
