New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued amendments to its guidance to address the classifications and presentation of changes in restricted cash in the statement of cash flows. The Company adopted this guidance retrospectively during the first quarter of fiscal 2017 and, as a result, the Company included restricted cash within the Consolidated Statements of Cash Flows; such amounts were not material. The retrospective adoption did not impact the prior period Consolidated Statements of Cash Flows since there was no restricted cash during any of the prior periods presented. Amounts included in restricted cash represent cash received from customers to settle invoices sold under the trade accounts receivable sale programs and is therefore contractually required to be set aside. The restrictions will lapse when the cash is remitted to the purchaser. In October 2016, the FASB issued a new accounting standard intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard eliminates the exception for an intra-entity transfer of an asset other than inventory and requires an entity to recognize the income tax consequences when the transfer occurs. This guidance is effective for the Company beginning in the first quarter of fiscal year 2019 and early adoption is permitted. This guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently assessing the impact this new standard may have on its Consolidated Financial Statements. In August 2016, the FASB issued new guidance related to the classification of certain cash receipts and cash payments, which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new standard addresses certain issues where diversity in practice was identified. It also amends existing guidance, which is principles based and often requires judgment to determine the appropriate classification of cash flows as operating, investing or financing activities and clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. This guidance is effective for the Company beginning in the first quarter of fiscal year 2019, and will generally require retrospective adoption. Early adoption is permitted. The Company is currently assessing the impact this new standard may have on its Consolidated Statements of Cash Flows. In March 2016, the FASB issued guidance that changes the accounting for certain aspects of share-based payments to employees. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid-in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The Company adopted this guidance prospectively during the first fiscal quarter of 2017. As such, beginning in the first fiscal quarter of 2017, the Company recognizes all excess tax benefits and tax deficiencies as income tax benefit or expense as a discrete item. An income tax benefit of approximately $4.9 million was recognized upon adoption, and for the three and nine months ended July 1, 2017, benefits of $0.2 million and $2.0 million, respectively, were also recognized. Due to the Company having a valuation allowance in the jurisdictions in which the income tax benefit was recorded, the income tax benefit was directly offset by an increase to the Company's valuation allowance resulting in no financial statement impact. The adoption did not have any other material impacts and will not materially impact the Company's future financial statements as long as the Company remains in a valuation allowance in the jurisdictions in which share-based compensation awards and options vest and are exercised, respectively. In February 2016, the FASB issued guidance that primarily requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company is currently in the process of assessing the impact of the adoption of the new standard on its Consolidated Financial Statements and the timing of adoption. In May 2014, the FASB issued new guidance which requires an entity to recognize revenue relating to contracts with customers that depicts the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for such goods or services. The guidance also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and is effective for the Company beginning in the first quarter of fiscal year 2019. The Company has determined that the new standard will result in a change to the timing of revenue recognition for a significant portion of the Company's revenue stream, whereby revenue will be recognized "over time" as opposed to at a "point in time" upon physical delivery. The new standard could have a material impact on the Company's consolidated financial statements upon initial adoption, primarily as the Company recognizes an increase in contract assets for unbilled receivables with a corresponding reduction in finished goods and work-in-process inventory. The Company has commenced implementation in accordance with the planned effective date. The new guidance allows for two transition methods in application - (i) retrospective to each prior reporting period presented, or (ii) prospective with the cumulative effect of adoption recognized on September 30, 2018, the first day of the Company's fiscal year 2019. The Company has not yet selected its transition method.
