Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles ("GAAP") in the United States of America ("U.S.") for interim financial information. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying Notes thereto included in our Annual Report on Form 10-K for the fiscal year ended April 1, 2016. The results of operations for the three and six months ended September 30, 2016, are not necessarily indicative of the results expected for the entire fiscal year.
Fiscal accounting year	We have a 52/53-week fiscal accounting year. Unless otherwise stated, references to three and six month ended periods in this report relate to fiscal periods ended September 30, 2016 and October 2, 2015. The six months ended September 30, 2016 and October 2, 2015, each consisted of 26 weeks. Our 2017 fiscal year consists of 52 weeks and ends on March 31, 2017.
Stock-based compensation	Stock-based compensation Stock-based compensation expense is measured at the grant date based on the fair value of the award and is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. No compensation cost is ultimately recognized for awards for which employees do not render the requisite service and are forfeited. We estimate forfeitures based on historical experience. Our granted stock-based awards principally consist of restricted stock units (“RSUs”). The fair value of each RSU is equal to the market value of our common stock on the date of grant. The fair values of RSUs are not discounted by the dividend yield because the Company’s RSUs include dividend-equivalent rights. We use the Black-Scholes model to determine the fair value of stock options. The Black-Scholes model incorporates various subjective variables, including our expected stock price volatility over the expected life of the options, actual and projected employee stock option exercise and forfeiture behaviors, risk-free interest rates, and expected dividends.
Recent accounting guidance not yet adopted	Recent accounting guidance not yet adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued authoritative guidance on revenue from contracts with customers. The new standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires significantly expanded disclosures about revenue recognition. As currently issued and amended, the standard is effective for us for our first quarter of fiscal 2019 and may be applied retrospectively or using the cumulative effect transition method. Early adoption as of the original effective date is permitted, but we do not intend to adopt the provisions of the new standard early. We expect to determine an adoption method by the end of fiscal 2017 and to have a preliminary qualitative assessment of the effect that the standard will have on our Consolidated Financial Statements. In January 2016, the FASB issued new authoritative guidance on financial instruments. The new guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. The update to the standard is effective for us for our first quarter of fiscal 2019, with early adoption permitted under limited circumstances. We are currently evaluating the effect the standard will have on our Consolidated Financial Statements. In February 2016, the FASB issued new authoritative guidance on lease accounting. Among its provisions, the standard requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet for operating leases and also requires additional qualitative and quantitative disclosures about lease arrangements. The standard is effective for us for our first quarter of fiscal 2020 with early adoption permitted. It is not expected that the adoption of the standard will have a material impact to our operating results. In March 2016, the FASB issued authoritative guidance simplifying several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, accounting for forfeitures, and classification of excess tax benefits on the statement of cash flows. The standard is effective for us for our first quarter of fiscal 2018, however, early adoption is permitted. We believe the most significant impact of the new guidance will be volatility to our effective tax rate from the change in accounting for income taxes and on its classification of excess tax benefit on the Consolidated Statements of Cash Flows. The impact of this standard on our effective tax rate for future periods will be dependent on our stock price at the time the awards vest and the number of awards that vest. In June 2016, the FASB issued new authoritative guidance on credit losses which changes the impairment model for most financial assets and certain other instruments. For trade receivables and other instruments, we will be required to use a new forward-looking “expected loss” model. Additionally, for available-for-sale debt securities with unrealized losses, we will measure credit losses in a manner similar to today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The standard will be effective for us for our first quarter of fiscal 2021. We are currently evaluating the effect the standard will have on our Consolidated Financial Statements.
