Note 2.

Summary of Significant Accounting Policies

The preparation of consolidated annual and quarterly financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. We have made a number of estimates and assumptions in the preparation of these consolidated financial statements. We can give no assurance that actual results will not differ from those estimates. Some of the more significant estimates include allowances for doubtful accounts, realizability of inventory, goodwill and other intangible assets, depreciation and amortization of long-lived assets, product liability, other postretirement benefits, asbestos, environmental and litigation matters, the valuation of deferred tax assets and sales return allowances.

There have been no material changes to our critical accounting policies and estimates from the information provided in Note 1 of the notes to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016.

Recently Issued Accounting Pronouncements

Standard not yet adopted as of September 30, 2017

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Under the new guidance, “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The new standard provides entities the option of using either a full retrospective or a modified approach to adopt the guidance.

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date (“ASU 2015-14”), which defers by one year the mandatory effective date of its revenue recognition standard, and provides entities the option to adopt the standard as of the original effective date. The new standard is now effective for annual reporting periods beginning after December 15, 2017, which for us is January 1, 2018, and interim periods within those annual periods. Early adoption is now permitted, but not before the original effective date, which for us is January 1, 2017.

To date, we have performed an assessment of the potential impacts of the pronouncement including a review of contracts with our significant customers. Based upon our initial assessment and contract review, we have not found a significant difference between the recognition of revenue under current accounting standards and ASU 2014-09 and, as such, do not anticipate that the adoption of this standard will have a material effect on our consolidated financial statements. However, we continue to evaluate the impact of this pronouncement on the recognition of revenue related to the return of cores from customers used in our manufacturing processes for air conditioning compressors, diesel injectors, diesel pumps, and turbo chargers. Adoption of the new standard may impact the timing of the recording of returned cores into inventory. Based upon our preliminary assessment of the impact on the recording of cores, we do not anticipate a material change in our net income.

In addition, we continue to evaluate the disaggregation of revenues disclosures required under the new standard with consideration given to a revenue disaggregation by major product group, geographic area and major sales channels. We anticipate using the modified retrospective method of adoption. We will be continuously assessing the new standard, the impact on our systems and processes, and the method of adoption through January 1, 2018, the date of implementation.

The following table provides a brief description of the additional recent accounting pronouncements that could have an impact on our financial statements:

Standard	Description	Date of adoption	Effects on the financial statements or other significant matters

Standards that are not yet adopted as of September 30, 2017

ASU 2016-02, Leases	This standard outlines the need to recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). For income statement purposes, the FASB retained the dual model, requiring leases to be classified as either operating or financing. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern.	January 1, 2019, with early adoption permitted	The new standard must be adopted utilizing a modified retrospective transition, and provides for certain expedients. The new standard will require that we recognize all of our leases, including our current operating leases, on the balance sheet. To date, we have taken an inventory of all of our operating leases, which consist primarily of real estate and auto leases, and are currently evaluating the appropriate discount rates to use in calculating the right to use asset. We will be continuously assessing the impact of the new standard and the impact on our systems and processes through January 1, 2019, our planned date of adoption.

ASU 2016-15, Statement of Cash Flows	This standard is intended to reduce diversity in practice and to provide guidance as to how certain cash receipts and cash payments are presented and classified in the statement of cash flows.	January 1, 2018, with early adoption permitted	The new standard requires application using a retrospective transition method. We do not anticipate that the adoption of this standard will have a material effect on our consolidated financial statements.

ASU 2017-04, Simplifying the Test for Goodwill Impairment	This standard is intended to simplify the accounting for goodwill impairment. ASU 2017-04 removes Step 2 of the test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.	January 1, 2020, with early adoption permitted	The new standard should be applied prospectively. We will consider the new standard when performing our annual impairment test and evaluate when we will adopt the new standard.

ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	This standard requires employers that present operating income in their consolidated statement of operations to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses (together with other employee compensation costs). The other components of net benefit cost, including amortization of prior service cost/credit, and settlement and curtailment effects, are to be included in other non-operating income (expense). The new standard requires retrospective reclassification of the effects of the new standard on the statement of operations.	January 1, 2018, with early adopted permitted	The new standard will require that we retrospectively reclassify all components of net periodic pension cost and net periodic postretirement benefit cost, other than the service cost component, in our statement of operations from selling, general and administrated expenses, as presently reported, to other non-operating income (expense).

Standard	Description	Date of adoption	Effects on the financial statements or other significant matters

Standards that were adopted

ASU 2015-17, Balance Sheet Classification of Deferred Taxes	This standard requires entities with a classified balance sheet to present all deferred tax assets and liabilities as noncurrent. The new guidance requires entities to offset all deferred tax assets and liabilities (and valuation allowances) for each tax-paying jurisdiction within each tax-paying component. The net deferred tax must be presented as a single noncurrent amount.	January 1, 2017	The adoption of the new standard resulted in the reclassification of deferred tax assets previously reported as current deferred tax assets to noncurrent deferred tax assets in our consolidated balance sheets. We adopted the new standard retrospectively, and as such, all prior period current deferred tax assets in our consolidated balance sheets have also been reclassified to noncurrent deferred tax assets for comparative purposes.

ASU 2015-11, Simplifying the Measurement of Inventory	This standard changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value for entities that measure inventory using first-in, first-out or average cost. In addition, this standard eliminates the requirement for these entities to consider replacement cost or net realizable value less an approximate normal profit margin when measuring inventory.	January 1, 2017	The prospective adoption of the new standard did not have a material effect on our consolidated financial statements.

ASU 2016-09, Improvements to Employee Share-Based Payment Accounting	This standard requires (1) that the tax effects related to share-based payments at settlement (or expiration) be recorded through the tax provision (benefit) in the income statement rather than in equity as permitted under prior guidance under certain circumstances; (2) that all tax-related cash flows resulting from share-based payments be reported as operating activities on the statement of cash flows, a change from the requirement to present windfall tax benefits as an inflow from financing activities and an outflow from operating activities; and (3) that when computing diluted earnings per share, the effect of “windfall” tax benefits be excluded from the hypothetical proceeds used to calculate the repurchase of shares under the treasury stock method.	January 1, 2017	We adopted the new standard prospectively. The adoption of the new standard did not have a material effect on our consolidated financial statements for the three months and nine months ended September 30, 2017, and based upon the current price of our common stock, we do not expect that the adoption of the new standard will have a material effect on our consolidated financial statements for the year ended December 31, 2017.
