Accounting Policies [Abstract] |
Significant Accounting Policies | Note 1. Significant Accounting Policies 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 Annual Report on Form 10-K, the terms “NN,” the “Company,” “we,” “our,” or “us” refer to NN, Inc., and its subsidiaries. We have historically reported results of operations in three reportable segments: the Precision Bearing Components Group (“PBC”), the Precision Engineered Products Group (“PEP”), and the Autocam Precision Components Group (“APC”). On August 17, 2017, we completed the sale of our global precision bearing components business (the “PBC Business”). Note 2 in these Notes to Consolidated Financial Statements provides further information on the sale of the PBC Business. We have 44 facilities in North America, Europe, South America and China. On January 2, 2018, we announced plans to implement a new enterprise and management structure designed to accelerate growth and align businesses. See Note 22 for discussion of the announcement. Basis of Presentation The accompanying consolidated financial statements are prepared in conformity 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 discontinued operations (see Note 2). Historical periods also reflect revisions related to prior period misstatements (see Prior Periods’ Financial Statement Revision) identified in the current year (see Note 21). In management’s opinion, the accompanying consolidated financial statements reflect all adjustments necessary to fairly present our results of operations, financial position, and cash flows for the periods presented. Except for per share data or as otherwise indicated, all dollar amounts presented in the tables in these Notes to Consolidated Financial Statements are in thousands of U.S. dollars. 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 Financial Statements The preparation of financial statements in conformity with U.S. GAAP requires management to make 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 could differ from those estimates. Prior Periods’ Financial Statement Revision In connection with the preparation of our consolidated financial statements for the year ended December 31, 2017, and the preparation of our interim financial statements, we identified various misstatements in our previously issued 2016 and 2015 annual financial statements and interim periods in 2016 and 2017. These prior period errors relate primarily to the (i) accounting for income and franchise taxes, (ii) accounting for the gain on the disposition of PBC Business, (iii) accounting for indemnification assets related to a prior acquisition, (iv) accounting for foreign currency transactions, (v) accounting for the translation of foreign subsidiary assets and joint venture, and (vi) other immaterial errors, including errors that had previously been adjusted for as out of period corrections in the period identified. We have assessed the materiality of the misstatements on the 2016 and 2015 financial statements in accordance with SEC Staff Accounting Bulletin (“SAB”) Topic 1.M, Materiality, codified in ASC Topic 250, Accounting Changes and Error Corrections, (“ASC 250”) and concluded that the misstatements were not material to any prior annual or interim periods. In accordance with ASC 250 (SAB Topic 1.N, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements), we have corrected for these misstatements, including the previously recorded out of period adjustments, for all periods presented by revising the accompanying consolidated financial statements. The accompanying notes to the consolidated financial statements reflect the impact of this revision. We have also reflected the impact of the revision in the applicable unaudited quarterly financial results. Refer to Note 20 and 21 for reconciliations between as originally reported and as revised annual and quarterly amounts, respectively. Accounting Standards Recently Adopted Stock Compensation. In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new standard changes how companies account for certain aspects of share-based payments to employees. Entities must recognize the income tax effects of awards in the statement of operations when the awards vest or are settled (i.e., additional paid-in capital pools were eliminated). The guidance changed regarding employers’ accounting for an employee’s use of shares to satisfy the employer’s statutory income tax withholding obligation and for forfeitures. The guidance was effective for public business entities for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. As of January 1, 2017, we adopted ASU 2016-09. Upon adoption, we reclassified $0.7 million in historical tax benefits from deferred taxes to retained earnings. We recognize excess tax benefits in income tax expense prospectively beginning in 2017. Excess tax benefits are presented in cash flows from operating activities in the statement of cash flows prospectively beginning in 2017. Tax payments in respect of shares withheld for taxes are classified in cash flows from financing activities in the statement of cash flows retrospectively for all periods presented. Beginning in 2017, the calculation of diluted net income (loss) per share now excludes tax benefits that would have generated more dilutive shares. The effects of the adoption were not material to the financial statements. Inventory. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, that simplifies the subsequent measurement of inventory by using only the lower of cost or net realizable value. We adopted ASU 2015-11 on January 1, 2017. The adoption of ASU 2015-11 did not have a material impact on our consolidated financial statements. Tax Reform Estimates. On December 22, 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (“U.S. Tax Cuts and Jobs Act of 2017”). In accordance with SAB 118, we have recorded $6.8 million of income tax expense in connection with the one-time transition tax related to the inclusion of deferred foreign earnings in U.S. taxable income. We have made a reasonable estimate of the effects of this foreign inclusion in our U.S. taxable income for the year ended December 31, 2017, and remeasurement of our deferred tax balances as of December 31, 2017, based on our interpretation of the computations and intent of Congress as defined in the U.S. Tax Cuts and Jobs Act of 2017. We do not expect any additional material adjustments; however, since the U.S. Tax Cuts and Jobs Act of 2017 was passed late in the fourth quarter of fiscal 2017 and ongoing guidance and accounting interpretation is expected over the next several months, it is reasonably possible that additional adjustments will be required during the one-year measurement period. Accounting Standards Not Yet Adopted Revenue Recognition. In May 2014, the FASB issued a new standard that provides a single, comprehensive revenue recognition model for all contracts with customers and supersedes most of the existing revenue recognition requirements. Under the new guidance, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The standard also requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Factors affecting implementation include, but are not limited to, identifying all the contracts that exist and whether incidental obligations or marketing incentives included in some of those contracts are performance obligations. Additionally, we evaluated the transfer of control of certain consignment and tooling contracts which may impact the timing of revenue recognition under the new standard. The standard is effective for us beginning January 1, 2018, with full retrospective or modified retrospective adoption permitted. We will adopt the standard utilizing the modified retrospective transition method. Under this transition method, we will recognize the cumulative effect of initially applying the new standard as an adjustment to the opening balance of retained earnings as of January 1, 2018, and will apply the new standard beginning with the most current period presented to contracts that are not completed at the date of initial application. We expect the adoption adjustment to be less than $0.1 million, which represents the net profit on certain contracts that were accounted for on a consignment basis prior to the new guidance but do not meet the consignment criteria under the new standard. We expect to utilize certain practical expedients allowed by the new standard. We intend to utilize the portfolio approach practical expedient to evaluate sales-related discounts on a portfolio basis to contracts with similar characteristics. We expect that the effect on our financial statements of applying the portfolio approach would not differ materially from applying the new standard to individual contracts. Leases. In February 2016, the FASB issued ASU 2016-02, Leases. ASU 2016-02 creates Topic 842, Leases, in the ASC and supersedes ASC 840, Leases. Entities that hold numerous equipment and real estate leases, in particular those with numerous operating leases, will be most affected by the new guidance. The lease accounting standard is effective for NN beginning January 1, 2019, with modified retrospective adoption required and early adoption permitted. The amendments in ASU 2016-02 are expected to impact balance sheets at many companies by adding lease-related assets and liabilities. This may affect compliance with contractual agreements and loan covenants. We have performed inquiries within segment locations and compiled information on operating and capital leases. We are currently evaluating the impacts of the lease accounting standard on our financial position, results of operations, and related disclosures. Upon adoption, we expect to recognize a right-of-use asset and a lease liability for nearly all of our leases that are currently classified as operating leases and are therefore not recorded on the balance sheet. We are in the process of gathering information that will enable us to estimate the amounts of those assets and liabilities. Note 14 presents future minimum lease payments under leases that are currently accounted for as off-balance sheet operating leases. Statement of Cash Flows. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). This guidance provides clarification on how certain cash receipts and cash payments are presented and classified on the statement of cash flows, with focus on eight specific areas in which cash flows have, in practice, been presented inconsistently. The guidance is effective for NN beginning January 1, 2018, and is required to be adopted using a retrospective approach if practicable, with early adoption permitted. The new cash flow guidance states that cash payments for debt prepayment costs should be classified as cash outflows for financing activities. We paid $31.6 million for debt prepayment costs in 2017 as discussed in Note 12. These debt prepayment costs are classified as cash outflows from operating activities in 2017. Under the new guidance, these costs will be reclassified to cash outflows from financing activities. The new guidance also requires entities to make an accounting policy election regarding classification of distributions received from equity method investees. Existing guidance does not currently address how an entity should determine which distributions represent returns on versus returns of investment. The lack of specific guidance has resulted in diversity in practice. The two allowable approaches are the “cumulative earnings” approach and the “nature of the distribution” approach, as defined by ASU 2016-15. Upon adoption of the new guidance on January 1, 2018, we will utilize the cumulative earnings approach for classifying distributions received from our joint venture investment (see Note 10). This policy election will have an immaterial impact to our consolidated statements of cash flows. Goodwill. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, that eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the current goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on the current Step 1 test). The standard is effective for us beginning with impairment tests performed on or after January 1, 2020, with early adoption permitted. We are currently evaluating the impact this new guidance is expected to have on our financial position or results of operations and related disclosures. 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. 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 2018-02, 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 Act from AOCI to retained earnings. The guidance also requires certain disclosures about stranded tax effects. ASU 2018-02 is effective for us on January 1, 2019, with early adoption in any period permitted. Entities may adopt the guidance using either at the beginning of the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the U.S. Tax Cuts and Jobs Act of 2017 is recognized. We are in the process of evaluating adoption method and the effects of this new guidance on our financial statements. Definition of a Business. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business. The new guidance requires an entity to first evaluate whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If that threshold is met, the set of assets and activities is not a business. If the threshold is not met, the entity evaluates whether the set meets the definition of a business. The new definition requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in the new revenue recognition guidance. The new guidance is effective for us beginning on January 1, 2018. We will apply the new definition of a business prospectively to any transactions occurring in 2018 or later. The new guidance will have no effect on our historical financial statements. Cash and Cash Equivalents Cash and cash equivalents include cash and highly liquid investments with original maturities of three months or less. 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 Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount upon recognition of a sale of goods when ownership and risk of loss is assumed by the customer. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The allowances are based on the number of days an individual receivable is past the invoice due date and on regular credit evaluations of our customers. In evaluating the credit worthiness of our customers, we consider numerous inputs including but not limited to the customers’ financial position, past payment history, relevant industry trends, cash flows, management capability, historical loss experience and economic conditions and prospects. Allowances are established when customer accounts are at risk of being uncollectible. Accounts receivable are written off at the time a customer receivable is deemed uncollectible. 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 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 betterments are capitalized. When a property item is retired, its cost and related accumulated depreciation are removed from the property accounts and any gain or loss is recorded in the consolidated Statements of 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 generally range from 15 to 40 years. Estimated useful lives for machinery and equipment generally range from 3 to 12 years. We depreciate leasehold improvements and buildings under capital lease over the shorter of the leased asset’s useful life or the lease term. Goodwill and Other Indefinite Lived Intangible Assets Goodwill 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. We have the option to make a qualitative assessment of whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount before applying the two-step goodwill impairment test. If we conclude that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, then we do not need to perform the two-step impairment test. For the years ended, December 31, 2017 and 2016, we chose not to perform the qualitative assessment but performed only the first step in the annual impairment test. The decision to perform a qualitative assessment or proceed to the two-step impairment test is an annual decision made by management. Based on the results of performing the first step of the impairment test, the fair value of the reporting units exceeded the carrying value of the reporting units at December 31, 2017 and 2016. If the qualitative assessment indicates it is more likely than not that the fair value is less than the carrying value, GAAP prescribes a two-step process for testing for goodwill impairments. The first step is to determine if the carrying value of the reporting unit with goodwill is less than the related fair value of the reporting unit. We consider three main approaches to value (cost, market and income) the fair value of the reporting unit and market based multiples of earning and sales methods obtained from a grouping of comparable publicly trading companies. We believe this methodology of valuation is consistent with how market participants would value reporting units. The discount rate and market based multiples used are specifically developed for the unit tested regarding the level of risk and end markets served. Even though we do use other observable inputs (Level 2 inputs) the calculation of fair value for goodwill would be most consistent with Level 3 inputs. If the carrying value of the reporting unit including goodwill is less than fair value of the reporting unit, the goodwill is not considered impaired. If the carrying value is greater than fair value then the potential for impairment of goodwill exists. The potential impairment is determined by allocating the fair value of the reporting unit among the assets and liabilities based on a purchase price allocation methodology as if the reporting unit was acquired in a business combination. The fair value of the goodwill is implied from this allocation and compared to the carrying value with an impairment loss recognized if the carrying value is greater than the implied fair value. We base our fair value estimates, in large part, on management business plans and projected financial information which are subject to a high degree of management judgment and complexity. Actual results may differ from projections, and the differences may be material. Impairment of Long-Lived Assets Long-lived tangible and intangible assets subject to amortization are tested for recoverability when changes in circumstances indicate the carrying value of these assets may not be recoverable. A test for recoverability is also performed when management has committed to a plan to dispose of a reporting unit or asset group. Assets to be held and used are tested for recoverability when indications of impairment are evident. Recoverability of a long-lived tangible 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 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. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit 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 not been made for income taxes on unremitted earnings of foreign subsidiaries as these earnings are deemed to be permanently reinvested. We recognize income tax positions that meet the more likely than not threshold and accrue interest and potential penalties related to unrecognized income tax positions which are recorded as a component of the provision (benefit) for income taxes. Revenue Recognition We recognize revenues based on the stated shipping terms with customers when these terms are satisfied and the risks of ownership are transferred to the customers. We have an inventory management program for certain customers whereby revenue is recognized when products are used by customers from consigned stock rather than at the time of shipment. Under both circumstances, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the sellers’ price is fixed and determinable, and collectability is reasonably assured. Share Based Compensation The cost of stock options, restricted stock and performance share units are 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 our stock options and a Monte Carlo simulation for the performance share units because these awards are not traded in open markets. We account for restricted stock by recognizing compensation expense ratably over the vesting period as specified in the award agreement. Compensation expense to be recognized is based on the closing stock price on the date of grant. Upon the adoption of ASU 2016-09 as of January 1, 2017, we recognize excess tax benefits in income tax expense prospectively beginning in 2017. Excess tax benefits are presented in cash flows from operating activities in the statement of cash flows prospectively beginning in 2017. Tax payments in respect of shares withheld for taxes are classified in cash flows from financing activities in the statement of cash flows retrospectively for all periods presented. 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 and accumulated other comprehensive income (“AOCI”) 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 products sold 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, 2017, 2016 and 2015. Transaction gains or losses on intercompany loan transactions are recognized as incurred in the “Other (income) expense, net” line in the Consolidated Statements of Operations and Comprehensive Income (Loss). Net Income Per Common Share Basic income per share reflects reported earnings divided by the weighted average number of common shares outstanding. Diluted income per share includes the effect of dilutive stock options and the respective tax benefits, unless inclusion would not be dilutive. 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 from 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 to 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.
