New Accounting Standards	L. New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). This update outlined a new comprehensive revenue recognition model that supersedes most current revenue recognition guidance and required companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflected the consideration to which the entity expected to be entitled in exchange for those goods or services. The Company adopted this standard effective May 1, 2018. See Note B in a discussion of the impact of the adoption of this standard. In August 2016, the FASB issued ASU 2016-15, “Cash Flow Classification of Certain Cash Receipts and Cash Payments,” which clarifies guidance on classification of certain transactions in the statement of cash flows, including classification of debt prepayments, debt extinguishment costs and contingent consideration payments after a business combination. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted this standard effective May 1, 2018. The adoption of this standard did not have a significant impact on the Company’s condensed consolidated financial position or results of operations. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows—Restricted Cash,” which requires that the statement of cash flows reconcile the change during the period in total cash, cash equivalents and restricted cash. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted this standard effective May 1, 2018. The adoption of this standard did not have a significant impact on the Company’s condensed consolidated financial position or results of operations. In March 2017, the FASB issued ASU 2017-07, “Compensation—Retirement Benefits—Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires that the service cost component of net periodic pension cost is presented in the same line as other compensation costs arising from services rendered by the respective employees during the year. The other components of net periodic pension cost are required to be presented in the income statement separately from the service cost component and outside of earnings from operations. This guidance allows for the service cost component to be eligible for capitalization when applicable. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company adopted this standard effective May 1, 2018. The adoption of this standard did not have a significant impact on the Company’s condensed consolidated financial position or results of operations. In May 2017, the FASB issued ASU 2017-09, “Compensation—Stock Compensation—Scope of Modification Accounting.” This guidance was issued in an effort to reduce diversity in practice as it relates to applying modification accounting for changes to the terms and conditions of share-based payment awards. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted this standard effective May 1, 2018. The adoption of this standard did not have a significant impact on the Company’s condensed consolidated financial position or results of operations.
