Income Taxes	5. Income Taxes The effective tax rate for the periods presented is primarily the result of income earned in the U.S., taxed at U.S. federal and state statutory income tax rates, income earned in foreign tax jurisdictions taxed at the applicable rates, as well as the impact of permanent differences between book and tax income. Our effective tax rate for the three months ended September 30, 2013 was 38.6% compared to 53.6% for the corresponding period of the prior fiscal year. During the three months ended September 30, 2013 and 2012, our income tax expense was driven primarily by pre-tax profitability in our foreign and domestic operations and the impact of permanent items, including non-deductible stock-based compensation expense, partially offset by a U.S. domestic production activity deduction. Our effective tax rate for the three months ended September 30, 2013 and 2012 differs from the U.S. federal statutory income tax rate primarily as a result of the impact of the permanent items. Deferred income taxes are recognized based on temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using the statutory tax rates and laws expected to apply to taxable income in the years in which the temporary differences are expected to reverse. Valuation allowances are provided against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the timing of the temporary differences becoming deductible. Management considers, among other available information, scheduled reversals of deferred tax liabilities, projected future taxable income, limitations of availability of net operating loss carryforwards, and other matters in making this assessment. We do not provide deferred taxes on unremitted earnings of foreign subsidiaries since we intend to indefinitely reinvest those earnings either currently or sometime in the foreseeable future. Unrecognized provisions for taxes on undistributed earnings of foreign subsidiaries, which are considered indefinitely reinvested, are not material to our consolidated financial position or results of operations.
