Interim Financial Statements	9 Months Ended

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 primarily for the aerospace and defense, electrical, automotive, medical, 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 and Going Concern The accompanying condensed consolidated financial statements have not been audited, except that the Condensed Consolidated Balance Sheet as of December 31, 2019, was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Annual Report”), which we filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 16, 2020. Historical periods presented reflect reclassifications for discontinued operations (see Note 2). Historical periods also reflect revisions that we disclosed in our 2019 Annual Report (see Note 3). 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, 2020 and 2019; financial position as of September 30, 2020, and December 31, 2019; and cash flows for the nine months ended September 30, 2020 and 2019, on a basis consistent with our audited consolidated financial statements other than the adoption of new accounting standards (see Accounting Standards Recently Adopted section below). 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 2019 Annual Report. The results for the three and nine months ended September 30, 2020, are not necessarily indicative of results for the year ending December 31, 2020, 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. In November 2019, we initiated a strategic review to evaluate a broad range of operational, financial, and strategic options to reduce leverage and enhance shareholder value, and we retained external advisors to assist in this effort. The strategic options we have evaluated included further cost savings and cash generation initiatives, more efficient capital deployment, changes to our debt and equity structure to improve financial flexibility and liquidity, and the sale of part or all of NN, among others. As discussed in our 2019 Annual Report, on December 11, 2019, we issued Series B Convertible Preferred Stock (“Preferred Stock”) for net proceeds of $95.7 million and used a portion of the proceeds to repay amounts due at that time on our Senior Secured Revolver. In December 2019, we amended our Credit Agreement which, in turn, extended the due date of our Senior Secured Revolver to July 20, 2022, reduced the total capacity under the Senior Secured Revolver to $75.0 million, and extended the due date of our Incremental Term Loan to October 19, 2022, matching the date of our longer-dated Senior Secured Term Loan. Additionally, as part of this amendment, our debt covenants were amended to establish more restrictive leverage ratios that also become more restrictive over time. Our Consolidated Net Leverage Ratio (the “financial leverage ratio”) covenant is required to be complied with on a quarterly basis at the end of each of our quarterly reporting periods. Our financial leverage ratio covenant is based upon our consolidated net indebtedness at each quarter end and our trailing twelve-month Adjusted EBITDA as defined in our Credit Agreement. In July 2020, we amended our Credit Agreement to waive compliance with the financial leverage ratio covenant for the second and third quarters of 2020. During this period, we are required to maintain minimum liquidity levels, provide certain financial and other information, and take certain other action as specified in the amendment. Failure to maintain the required minimum liquidity levels or satisfy other requirements set forth in the amendment would allow the revolving credit lenders, the Senior Secured Term loan lenders, and the Incremental Term Loan lenders to cause amounts outstanding under our credit facility to become immediately due and payable and would have a material, adverse impact on our financial position. In August 2020, we entered into an agreement to sell our Life Sciences business (see Note 2). The sale closed on October 6, 2020, at which time we received cash proceeds of $757.2 million. We immediately prepaid $700.0 million in the aggregate on the Senior Secured Term Loan and the Incremental Term Loan. We also paid in full the outstanding balance on the Senior Secured Revolver. In August 2020, we amended our Credit Agreement to obtain the lenders’ consent to the sale of the Life Sciences business, subject to certain terms and conditions. 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), we have evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the Condensed Consolidated Financial Statements are issued. We rely on cash flow generated from operations and available borrowings under our Senior Secured Revolver to fund our working capital and other operating and investing needs. Our ability to borrow under the Senior Secured Revolver is based on our continued compliance with the minimum liquidity requirements and, for periods beginning in the fourth quarter of 2020, the financial leverage ratio covenant, as defined, which became more restrictive upon the occurrence of a qualified sale transaction, which occurred on October 6, 2020. The full extent of the effect of the coronavirus (“COVID-19”) pandemic on our customers, our supply chain and our business cannot be reasonably assessed at this time although we expect our full year 2020 results of operations to be adversely affected. We have developed a plan to mitigate the impact of COVID-19, which includes the implementation of a series of specific and identified cost reductions in both our corporate and business groups, in addition to actions already taken, including further reducing our direct and indirect labor costs and benefits. The impact of COVID-19 on our operating results will depend on future developments, which are highly uncertain and cannot be predicted, including governmental and business reactions to the pandemic. We have made appropriate accounting estimates based on the facts and circumstances available as of the reporting date. If there are differences between these estimates and actual results, our consolidated financial statements may be materially affected. Based on available borrowing capacity of the Senior Secured Revolver, the reduction in debt service costs as a result of the debt prepayment with net proceeds from the sale of the Life Sciences business in October 2020, and cash flows expected to be generated from operations and investing activities, we anticipate that our cash and cash equivalents are sufficient to support our operations and meet our obligations, and that we will be able to maintain compliance with the existing financial leverage ratio covenant for the next twelve months from issuance of these financial statements. Accordingly, we believe that the conditions that raised substantial doubt about our ability to continue as a going concern as disclosed in our Quarterly Report for the period ended June 30, 2020, have been resolved. Accounting Standards Recently Adopted Financial Instruments - Credit Losses. In June 2016, the Financial Accounting Standards Board (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. In November 2019, the SEC issued Staff Accounting Bulletin (“SAB”) No. 119, codified in ASC Topic 326, Financial Instruments-Credit Losses, which provides guidance on accounting of credit losses. We adopted ASU 2016-13 on January 1, 2020, using the modified retrospective transition method which resulted in no material adjustment to our financial statements as of January 1, 2020. 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 streamlines disclosures of Level 3 fair value measurements. The modified disclosures were effective for us beginning in the first quarter of 2020. ASU 2018-13 changes disclosures only and does not impact our financial condition, results of operations, or cash flows. 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 apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. We adopted ASU 2018-15 as of January 1, 2020, prospectively. We have had no such costs after the adoption date, and we do not expect the new guidance to have a material impact on our financial statements. Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. Among other things, for all types of hedging relationships, the guidance allows an entity to change the reference rate and other critical terms related to reference rate reform without having to remeasure the value or reassess a previous accounting determination. The amendments in this guidance should be applied on a prospective basis and, for companies with a fiscal year ending December 31, are effective from January 1, 2020, through December 31, 2022. We adopted this guidance effective January 1, 2020. When the transition occurs, we expect to apply this expedient to new transactions that reference LIBOR or another reference rate that is discontinued, through December 31, 2022. The adoption of this ASU is not expected to have a material impact on our consolidated financial statements. Accounting Standards Not Yet Adopted Income Taxes. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, (“ASU 2019-12”) as part of its initiative to reduce complexity in accounting standards. ASU 2019-12 removes certain exceptions and provides simplification to specific tax items to improve consistent application. This standard is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. We are currently evaluating the impact on our financial statements and related disclosures.
