Accounting Policies [Abstract]
Income Taxes	Income Taxes The Company calculates its interim income tax provision in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 270, “Interim Reporting” (“ASC 270”) and ASC Topic 740, “Accounting for Income Taxes” (“ASC 740”). At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items is recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws, rates or tax status is recognized in the interim period in which the change occurs. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including the expected operating income for the year, permanent and temporary differences as a result of differences between amounts measured and recognized in accordance with tax laws and financial accounting standards, and the likelihood of recovering deferred tax assets generated in the current fiscal year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or the tax environment changes.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed using the weighted-average number of common shares outstanding. Diluted earnings per share is computed using the weighted-average number of common shares outstanding adjusted for the incremental shares attributed to outstanding options to purchase common stock and nonvested restricted stock using the treasury stock method, if dilutive. In periods where a net loss is reported, incremental shares are excluded as their effect would be anti-dilutive. In such circumstances, the weighted-average number of shares outstanding in the basic and diluted earnings per common share calculations will be the same. Anti-dilutive options and nonvested shares are excluded from the computation of diluted earnings per share because either the option exercise price or the grant date fair value of the nonvested share is greater than the market price of the Company’s common stock. Options to purchase 7.6 million shares of common stock in the second quarter of fiscal 2013, and 5.2 million and 6.2 million shares of common stock in the first half of fiscal 2014 and 2013, respectively, were excluded from the computation of diluted earnings per share as their effect would have been anti-dilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-08, "Presentation of Financial Statements and Property, Plant, and Equipment " and "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity". The ASU amendment changes the requirements for reporting discontinued operations in Subtopic 205-20. The amendment is effective on a prospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2014. Early adoption is permitted for disposals that have not been reported in financial statements previously issued. Based on the Company's evaluation of the ASU, its adoption of this update is not expected to have a material impact on the Company's financial position or results of operation. In May 2014, the FASB issued ASU No. 2014-09, "Revenue From Contracts with Customers". The ASU amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The new standard is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled to when products are transferred to customers. The Company is required to adopt this new standard for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted. The new revenue accounting standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. Based on the Company's evaluation of the ASU, its adoption of this update is not expected to have a material impact on the Company's financial position or results of operation.
Stock Compensation	The Company accounts for stock-based compensation expense in accordance with ASC Topic 718, “Stock Compensation” (“ASC 718”). The Company uses the Black-Scholes option-pricing model to estimate the grant date fair value of its stock options. Forfeitures are estimated at the date of grant based on historical rates and reduce the compensation expense to be recognized during the vesting period. The expected term of options granted is derived primarily from historical data on employee exercises adjusted for expected changes to option terms, if any. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant. Expected volatility is based primarily on the historical volatility of the Company’s common stock. The Company records stock-based compensation expense using the straight-line method over the vesting period, which is generally three to four years. The Company’s stock-based awards generally begin vesting one year after the grant date and, for stock options, expire in seven to ten years or three months after termination of employment with the Company. The Company’s stock-based compensation expense resulted from awards of stock options, restricted stock, and stock appreciation rights, as well as from shares issued under the ESPP.
