New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), and has modified the standard thereafter. The core principal of the standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The new revenue standard will be effective for the Company on February 1, 2018. The standard permits the use of either a full retrospective method, where the standard is applied to each prior reporting period presented or a cumulative effect transition method, or modified retrospective method, where the cumulative effect of initially applying the standard is recognized at the date of initial application. We anticipate using the modified retrospective method and we are currently evaluating the effect the new revenue standard will have on our consolidated financial statements. In July 2015, the FASB issued authoritative guidance to simplify the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizable value test. This guidance is effective for fiscal years beginning after December 15, 2016, which will be the Company’s first quarter of fiscal 2018, and requires prospective adoption, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements or related disclosures. In February 2016, the FASB issued a comprehensive new lease standard which will supersede previous lease guidance. The standard requires a lessee to recognize assets and liabilities related to long-term leases that were classified as operating leases under previous guidance in its balance sheet. An asset would be recognized related to the right to use the underlying asset and a liability would be recognized related to the obligation to make lease payments over the term of the lease. The standard also requires expanded disclosures surrounding leases. The standard is effective for fiscal periods beginning after December 15, 2018, which will be the Company’s first quarter of fiscal 2020, and requires modified retrospective adoption, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures, but expects there will be a significant increase in its long-term assets and liabilities resulting from the adoption. In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting (''ASU 2016-09''). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. The Company will adopt this ASU in the first quarter of fiscal 2018. The Company has excess tax benefits for which a benefit could not be previously recognized of approximately $172,000. Upon adoption the balance of the unrecognized excess tax benefits will be reversed with the impact recorded to retained earnings. In March 2016, the FASB issued authoritative guidance to simplify the accounting for certain aspects of share-based compensation. This guidance addresses the accounting for income tax effects at award settlement, the use of an expected forfeiture rate to estimate award cancellations prior to the vesting date and the presentation of excess tax benefits and shares surrendered for tax withholdings on the statement of cash flows. This guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled which is a change from the current guidance that requires such activity to be recorded in paid-in capital within stockholder’s equity. This guidance will be applied prospectively and may create volatility in the Company’s effective tax rate when adopted depending largely on future events and other factors which may include the Company’s stock price, timing of stock option exercises, the value realized upon vesting or exercise of shares compared to the grant date fair value of those shares and any employee terminations. This guidance eliminates the requirement to defer recognition of an excess tax benefit until the benefit is realized through a reduction to taxes payable. This guidance will be applied on a modified-retrospective basis with a cumulative-effect adjustment to retained earnings. This guidance also eliminates the requirement to estimate forfeitures, but rather provides for an election that would allow entities to account for forfeitures as they occur. The Company plans to adopt this election beginning in the first quarter of fiscal 2018 using the modified retrospective method and expects that the impact from recording forfeitures as they occur as well as the cumulative adjustment to retained earnings resulting from adoption will not be material. This guidance also changes the presentation of excess tax benefits from a financing activity to an operating activity in the statement of cash flows. The Company plans to adopt this retrospectively and does not expect a material impact on its consolidated statements of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, which will be the Company’s first quarter of fiscal 2018, with early adoption permitted. In June 2016, the FASB issued authoritative guidance related to the measurement of credit losses on financial instruments. This guidance is effective for fiscal years beginning after December 15, 2019, which will be the Company’s first quarter of fiscal 2021. Early adoption is permitted for fiscal periods beginning after December 15, 2018, which will be the Company’s first quarter of fiscal 2020. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments in the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, which will be the Company’s first quarter of fiscal 2019, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures. In November 2016, the FASB issued authoritative guidance related to the presentation of restricted cash in the statement of cash flows. This guidance 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 beginning after December 15, 2017, which will be the Company’s first quarter of fiscal 2019, and requires retrospective adoption, with early adoption permitted. Other than this change in presentation within the Company’s consolidated statements of cash flows, the adoption of this guidance is not expected to have an impact on the Company’s consolidated financial statements or related disclosures. In March 2017, the FASB issued authoritative guidance related to the presentation of net periodic pension cost in the income statement. This guidance 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 period. 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 also allows for the service cost component to be eligible for capitalization when applicable. This guidance is effective for fiscal years beginning after December 15, 2017, which will be the Company’s first quarter of fiscal 2019, and requires retrospective adoption for the presentation of the service cost component and other components of net periodic pension cost in the income statement and prospective adoption for capitalization of the service cost component. Early adoption is permitted at the beginning of a fiscal year. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements and related disclosures.
