Accounting Policies [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 primarily for the electrical, automotive, general industrial, aerospace and defense, and medical markets. As used in this Annual Report on Form 10-K (this “Annual Report”), the terms “NN,” the “Company,” “we,” “our,” or “us” refer to NN, Inc., and its subsidiaries. We have 32 facilities in North America, Europe, South America, and China.
Basis of Presentation | Basis of PresentationThe accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Certain prior period amounts have been reclassified to conform to the current year’s presentation. Historical periods presented reflect reclassifications for discontinued operations (see Note 2). Except for per share data or as otherwise indicated, all U.S. dollar amounts presented in the tables in these Notes to Consolidated Financial Statements are in thousands.
Principles of Consolidation | Principles of Consolidation Our consolidated financial statements include the accounts of NN, Inc., and its wholly owned subsidiaries. We own a 49% interest in a joint venture which we account for using the equity method (see Note 10). All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates in the Preparation of Consolidated Financial Statements | Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to use estimates and assumptions that affect the reported amounts of certain assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results may differ from those estimates.
Accounting Standards Recently Adopted | 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 Accounting Standards Codification (“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 impact on our consolidated financial statements. 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 consolidated financial statements. 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 consolidated 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 | Accounting Standards Not Yet Adopted 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 consolidated financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. We are currently evaluating the impact on our consolidated financial statements and related disclosures. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, (“ASU 2020-06”) which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. In addition, ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception. Further, for the diluted earnings-per-share calculation, the new guidance requires entities to use the if-converted method for all convertible instruments and generally requires entities to include the effect of share settlement for instruments that may be settled in cash or shares, among other things. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Either the full or modified retrospective adoption method is allowed. We are currently evaluating the impact on our consolidated financial statements and related disclosures.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash and highly liquid investments with original maturities of three months or less. We maintain cash balances in transaction accounts with various financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). Although we maintain balances that exceed the federally insured limit, we have not experienced any losses related to these balances, and we believe credit risk to be minimal. We had approximately $17.0 million and $12.7 million in cash and cash equivalents as of December 31, 2020 and 2019, respectively, held at foreign financial institutions.
Fair Value Measurements | 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.
Accounts Receivable and Allowance for Credit Losses | Accounts Receivable and Allowance for Credit Losses Trade accounts receivable are recorded at their net realizable value. We maintain allowances for estimated losses resulting from the inability of our customers to make required payments. The allowances are based on the amount that we ultimately expect to collect from our customers. We evaluate the collectability of accounts receivable based on a combination of factors including number of days receivables are past due, historical collection experience, current market conditions, and forecasted direction of economic and business environment. Accounts receivable are written off at the time a customer receivable is deemed uncollectible.
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using standard costs, which approximates the average cost method. Our policy is to expense abnormal amounts of idle facility expense, freight, handling cost, and waste included in cost of products sold. 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. 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. Inventories also include tools, molds, and dies in progress that we are producing and will ultimately sell to our customers. These inventories are also carried at the lower of cost or net realizable value.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Assets to be disposed of are stated at the 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 improvements 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 Operations and Comprehensive Income (Loss). 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 also includes tools, molds, and dies used in manufacturing. Depreciation is calculated based on historical cost using the straight-line method over the estimated useful lives of the depreciable assets. Estimated useful lives for buildings and land improvements generally range from 10 to 40 years. Estimated useful lives for machinery and equipment generally range from 3 to 12 years. Estimated useful lives for leasehold improvements are based on the life of the lease.
Goodwill and Other Indefinite Lived Intangible Assets | Goodwill and Other Indefinite Lived Intangible AssetsGoodwill is tested for impairment on an annual basis in the fourth quarter and between annual tests if a triggering event occurs. The impairment analysis is performed at the reporting unit level. An impairment charge is calculated based on a reporting unit’s carrying amount in excess of its fair value (i.e., step 1 of the two-step impairment test). 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.
Impairment of Long-Lived Assets | Impairment of Long-Lived AssetsLong-lived tangible and intangible assets subject to depreciation or 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 or 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, then the asset is considered impaired and adjusted to fair value which is then depreciated or amortized over its remaining useful life. Assets to be disposed of are recorded at the lesser of carrying value or fair value less costs of disposal.
Equity Method Investments | Equity Method Investments Our equity method investment is subject to a review for impairment if, and when, circumstances indicate that a decline in value below its carrying amount may have occurred. Examples of such circumstances include, but are not limited to, a significant deterioration in the earnings performance or business prospects of the investee; a significant adverse change in the regulatory, economic or technological environment of the investee; a significant adverse change in the general market condition of either the geographic area or the industry in which the investee operates; and recurring negative cash flows from operations. If management considers the decline to be other than temporary, we would write down the investment to its estimated fair market value.
Income Taxes | 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 consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. 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 been made for income taxes on unremitted earnings of certain foreign subsidiaries as these earnings are not 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. We treat global intangible low-taxed income (“GILTI”) as a periodic charge in the year in which it arises and therefore do not record deferred taxes for basis differences associated with GILTI. We eliminate disproportionate tax effects from accumulated other comprehensive income (loss) when the circumstances upon which they are premised cease to exist.
Revenue Recognition | Revenue RecognitionWe recognize revenues 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.
Share Based Compensation | Share Based CompensationThe cost of stock options, restricted stock, and performance share units is recognized as compensation expense over the vesting periods based on the grant date fair value, net of expected forfeitures. We determine grant date fair value using the Black Scholes financial pricing model for stock options and a Monte Carlo simulation for performance share units that include a market condition for vesting because these awards are not traded in open markets. We determine grant date fair value using the closing price of our common stock on the date of grant for restricted stock and performance share units that include performance conditions for vesting.
Foreign Currency Translation | Foreign Currency Translation Assets and liabilities of our foreign subsidiaries are translated at current exchange rates. 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 (loss) and accumulated other comprehensive income (loss) within stockholders’ equity. 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 as incurred in either cost of sales or selling, general and administrative expense in the Consolidated Statements of Operations and Comprehensive Income (Loss) and were immaterial to the years ended December 31, 2020, 2019, and 2018. Transaction gains or losses on intercompany loan transactions are recognized as incurred in the “Other expense (income), net” line in the Consolidated Statements of Operations and Comprehensive Income (Loss). For the years ended December 31, 2020, 2019, and 2018, transaction gains or losses on intercompany loan transactions were $0.8 million, $0.4 million, and $3.6 million, respectively.
Net Income (Loss) Per Common Share | Net Income (Loss) Per Common Share We are required to allocate earnings or losses for a reporting period to common stockholders and participating securities using the two-class method to compute earnings per share. The two-class method is an earnings allocation formula that treats participating securities as having rights to earnings that otherwise would have been available to common stockholders. Participating securities may participate in undistributed earnings with common stock whether or not that participation is conditioned upon the occurrence of a specified event. Under the two-class method, our net income (loss) is reduced (or increased) by the amount that has been or will be distributed to our participating security holders. Preferred shares are participating securities that participate in earnings but do not participate in losses. Basic net income (loss) per common share is computed by dividing net income (loss) allocable to common shares by the weighted average number of common shares outstanding. Diluted net income (loss) per common share includes the effect of warrants, convertible preferred stock, stock options and the respective tax benefits unless inclusion would not be dilutive.
Business Combinations | Business Combinations We allocate the total purchase price of tangible and intangible assets acquired and liabilities assumed based on their estimated fair values as of the business combination date, with the excess purchase price recorded as goodwill. The purchase price allocation process requires us to use significant estimates and assumptions, including fair value estimates, as of the business combination date. Although we believe the assumptions and estimates we have made are reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired company. Our assumptions and estimates are also partially based on valuation models that incorporate projections of expected future cash flows and operating plans and are inherently uncertain. Valuations are performed by management or third-party valuation specialists under management’s supervision. In determining the fair value of assets acquired and liabilities assumed in business combinations, as appropriate, we may use one of the following recognized valuation methods: the income approach (including discounted cash flows, relief from royalty and excess earnings model), the market approach, or the replacement cost approach. Examples of significant estimates used to value certain intangible assets acquired include but are not limited to: •sales volume, pricing, and future cash flows of the business overall; •future expected cash flows from customer relationships, and other identifiable intangible assets, including future price levels, rates of increase in revenue, and appropriate attrition rate; •the acquired company’s brand and competitive position, royalty rate quantum, as well as assumptions about the period of time the acquired brand will continue to benefit the combined company’s product portfolio; and •cost of capital, risk-adjusted discount rates, and income tax rates. Different assumptions regarding projected performance and other factors associated with the acquired assets may affect the amount recorded under each type of asset and liability. The valuations of property, plant and equipment, intangible assets, goodwill and deferred income tax liabilities depend heavily on assumptions. Subsequent assessment could result in future impairment charges. We refine these estimates over a measurement period not to exceed one year to reflect new information obtained surrounding facts and circumstances existing at the acquisition date.
