New Accounting Guidance	New Accounting Guidance: Pension costs In March 2017, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the income statement presentation of pension and postretirement costs. This guidance requires companies to continue to present the service cost component of net periodic benefit cost within the same financial statement line item as other employee compensation costs; however, other components of net benefit cost are required to be presented outside of results from operations. The Company adopted this guidance, on a retrospective basis, for its first quarter of fiscal 2018. As a result, during the first quarter of fiscal 2018, the Company recorded $0.8 million of its net periodic benefit cost within other income and expense. In addition, the Company reclassified net periodic benefit cost related to its pension and postretirement plans totaling $0.7 million ($0.3 million from cost of sales and $0.4 million from selling, general and administrative (“SG&A”) expenses) to other income and expense for the first quarter of fiscal 2017. Share-based compensation In March 2016, the FASB issued new guidance to simplify several aspects of accounting for share-based payment transactions. The Company adopted this guidance for its first quarter of fiscal 2018. The Company elected to account for forfeitures in the period in which they occur and recorded a cumulative-effect adjustment to equity. In addition, the Company prospectively adopted the guidance requiring all excess tax benefits or deficiencies to be recognized as income tax expense or benefit when awards are settled. The provisions of this guidance did not have a material impact on the Company's consolidated financial statements. As a result of its adoption, the Company recorded a $0.4 million increase to both deferred tax assets and equity as of April 1, 2017. Leases In February 2016, the FASB issued new comprehensive lease accounting guidance that supersedes existing lease accounting guidance. Upon adoption of this new guidance, the Company will be required to recognize most leases on its balance sheet. This guidance is effective for the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements. Revenue recognition In May 2014, the FASB issued new guidance that outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The core principle of the new guidance is that companies are to recognize revenue to depict the transfer of 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 guidance also includes a cohesive set of disclosure requirements intended to provide users of financial statements with comprehensive information about revenue arising from contracts with customers. This new guidance is effective for the Company’s first quarter of fiscal 2019 and allows for either a full-retrospective or a modified-retrospective transition method. The Company is currently in the process of assessing customer contracts and evaluating contractual provisions that may result in a change in the timing of revenue recognized in comparison with current guidance. Under current guidance, the Company generally recognizes revenue when products are shipped and risk of loss has transferred to the customer. The Company is evaluating whether contractual provisions may provide an enforceable right to payment for its customized products, which may require revenue recognition prior to the product being shipped to the customer. In addition, the Company is evaluating pricing provisions contained in certain of its customer contracts to determine the appropriate timing of revenue recognition based upon the new guidance. The Company continues to evaluate the impact this new guidance will have on its consolidated financial statements.
