Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax provision (benefit) of $1.6 million and $(1.6) million for the three and six months ended March 31, 2015, respectively. The tax provision is driven by global income during the current quarter and interest related to unrecognized tax benefits. The tax benefit is driven by U.S. pre-tax losses in the first quarter of fiscal 2015, $0.6 million of reductions in unrecognized tax benefits resulting from the expiration of the statute of limitations in various foreign jurisdictions and $0.9 million of tax benefits resulting from the reinstatement of the U.S. federal research and development tax credit, retroactive to January 1, 2014. These benefits are partially offset by foreign income taxes and interest related to unrecognized tax benefits. The Company recorded an income tax provision of $1.1 million and $1.9 million for the three and six months ended March 31, 2014, respectively. These tax provisions substantially consist of U.S. and foreign income taxes, as well as interest related to unrecognized tax benefits. The Company evaluates the realizability of its deferred tax assets by jurisdiction and assesses the need for a valuation allowance on a quarterly basis. As of March 31, 2015, the Company has continued to maintain a valuation allowance in the U.S. against certain tax credits and state net operating losses due to the uncertainty of their realization based on long-term Company forecasts and the expiration dates on these attributes. The Company has also continued to maintain a valuation allowance in certain jurisdictions that have not generated historical cumulative profitability. The Company is subject to U.S. federal income tax and various state, local and foreign income taxes in various jurisdictions. The amount of income taxes paid is subject to the Company's interpretation of applicable tax laws in the jurisdictions in which it files. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world. The Company has income tax audits in progress in various jurisdictions in which it operates. In the Company's U.S. and foreign jurisdictions, the years that may be examined vary, with the earliest tax year being 2008. Based on the outcome of these examinations, or the expiration of statutes of limitations for specific jurisdictions, the related unrecognized tax benefits could change from those recorded in the Company's Consolidated Balance Sheets. It is reasonably possible that the unrecognized tax benefit will be reduced by approximately $1.3 million during the next twelve months as the result of the expiration of statutes of limitations.
