Description of new accounting pronouncements |  |  | In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined.

The new guidance also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. The new guidance should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption.

Company And Summary Of Significant Accounting Policies [Line Items] |  |  |  |  |
Description of new accounting pronouncements |  |  | In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 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 a customer. This guidance will replace most existing revenue recognition guidance and will be effective for the Company beginning in fiscal year 2019, including interim periods within that reporting period, based on the FASB decision in July 2015 (ASU 2015-14, Revenue from Contracts with Customers – Deferral of the Effective Date) to delay the effective date of the new revenue recognition standard by one year, but providing entities a choice to adopt the standard as of the original effective date. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing, which clarifies the implementation guidance on identifying performance obligations and the licensing implementation guidance.

These standards permit the use of either the retrospective or cumulative effect transition method. The Company has not selected a transition method and is currently evaluating the impact these standards will have on its consolidated financial statements and disclosures. |  |

Description of new accounting pronouncements |  |  | In April 2015, the FASB issued ASU 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. This guidance became effective for the Company beginning in the first quarter of fiscal year 2017. The Company elected to adopt this guidance on a prospective basis and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements and disclosures. |  |

Description of new accounting pronouncements |  |  | In April 2015, the FASB issued ASU 2015-03, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. |  |

Company And Summary Of Significant Accounting Policies [Line Items] |  |  |  |  |
Description of new accounting pronouncements |  |  | In August 2015, the FASB issued ASU 2015-15 which provides additional guidance to ASU 2015-03, which did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 noted that staff of the Securities and Exchange Commission (the SEC) would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This guidance became effective for the Company beginning in the first quarter of fiscal year 2017 and was applied on a retrospective basis, wherein the condensed consolidated balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the new guidance. As a result, the Company reclassed unamortized debt issuance costs related to the Company’s 2020 Notes and the Ex-Im Credit Facility from prepaid expenses and other current assets and from other assets (long-term) to senior notes, net, and other long-term debt, net, respectively, within its consolidated balance sheets as of March 31, 2016. In accordance with ASU 2015-15, the Company has elected to continue to present debt issuance costs related to the Revolving Credit Facility as an asset and subsequently amortize the deferred debt issuance costs over the term of the Revolving Credit Facility arrangement. |  |

Description of new accounting pronouncements |  |  | In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance will become effective for the Company beginning in fiscal year 2021, with early adoption permitted. The new guidance is required to be applied on a modified-retrospective basis. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures. |  |

Description of new accounting pronouncements |  |  | In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740). ASU 2016-16 requires that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs as opposed to when the asset has been sold to an outside party. The new standard will become effective for the Company beginning in fiscal year 2019, with early adoption permitted. The new standard will require a modified retrospective basis through cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption.

Description of new accounting pronouncements |  |  | In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 provides guidance regarding management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The new standard requires management to perform interim and annual evaluations and sets forth principles for considering the mitigating effect of management’s plans. The standard mandates certain disclosures when conditions give rise to substantial doubt about a company’s ability to continue as a going concern within one year from the financial statement issuance date. This guidance is effective for the Company in fiscal year 2017, with early application permitted. The Company early adopted the guidance, which did not have a material impact on the Company’s consolidated financial statements and disclosures. |  |
