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, 2017, except for changes made as a result of the adoption of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, described under the heading, “Recently Issued Accounting Pronouncements” below and in Note 3, “Net Sales.”

Recently Issued Accounting Pronouncements

Standards that were adopted

Revenue from Contracts with Customers

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, (“ASU 2014-09”) which replaces numerous requirements in U.S. generally accepted accounting principles, including industry-specific requirements, and provide companies with a single comprehensive revenue recognition model for recognizing revenue from contracts with customers. 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 two permitted transition methods under the new standard are (1) the full retrospective method, in which case the standard would be applied to each prior reporting period presented, with the cumulative effect of applying the standard recognized at the earliest period presented, or (2) the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application.

Effective January 1, 2018, we adopted the requirements of ASU 2014-09, Revenue from Contracts with Customers, using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We expect the impact of the adoption of the new standard to be immaterial to our net income on an ongoing basis.

The adoption of the new standard did not result in a material difference between the recognition of revenue under ASU 2014-09 and prior accounting standards. For the majority of our net sales, revenue continues to be recognized when products are shipped from our distribution facilities, or when received by our customers, depending upon the terms of the contract. Under the new revenue standard, (1) the return of cores from customers used in our manufacturing processes for air conditioning compressors, diesel injectors, and diesel pumps is estimated and recorded as unreturned customer inventories at the time of sale, and (2) overstock returns are recorded gross of expected recoveries. Adoption of the new standard resulted in the recording of unreturned customer inventories, and an increase in accrued core liabilities and accrued customer returns, with partially offsetting changes in net sales and cost of sales, and no material change to our net income on an ongoing basis.

The cumulative effect of the changes made to our consolidated balance sheet as of January 1, 2018 for the adoption of ASU 2014-09 is as follows (in thousands):

	Balance at December 31, 2017		Adjustments Due to Adoption of ASU 2014-09			Balance at January 1, 2018
Balance Sheet
Unreturned customer inventories	$	—	$	19,950		$	19,950
Accrued customer returns		35,916		6,670			42,586
Accrued core liability		11,899		14,469			26,368
Retained earnings		357,153		(1,189	)		355,964

The adoption of ASU 2014-09 resulted in the following changes to our consolidated balance sheet as of March 31, 2018 and our consolidated statement of operations for the three months ended March 31, 2018 (in thousands):

	As Reported		Balances Without Adoption of ASU 2014-09		Effect of Change

Unreturned customer inventories	$	18,674	$	—	$	18,674
Prepaid expenses and other current assets		12,672		12,810		(138	)
Accrued customer returns		43,031		35,817		7,214

The following table provides a brief description of the impact of additional recently adopted accounting pronouncements on our financial statements:

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

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	The retrospective adoption of the new standard did not result in any changes in our reporting of cash receipts and cash payments in our consolidate statement of cash flows.

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	The adoption of the new standard resulted in the reclassification of 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, to other non-operating income (expense). We adopted the new standard retrospectively, and as such, all prior period amounts have been reclassified for comparative purposes.

Standards that are not yet adopted as of March 31, 2018

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

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 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.
