13.Income Taxes

Income tax expense as a percentage of income from continuing operations before income tax expense was 16% and 31% for the three month periods ended September 30, 2012 and 2011, respectively and 17% and 32% for the six-month periods then ended, respectively.  Typically these percentages vary from the U.S. statutory rate primarily due to varying effective tax rates at the Company's foreign subsidiaries, and the jurisdictional mix of taxable income for these subsidiaries.  We estimate that the effective tax rate related to continuing operations will be approximately 15% to 20% for fiscal 2013 based on the forecasted jurisdictional mix of taxable income.

During the fiscal year ended March 31, 2011, the Company recorded a non-cash charge of $42,983,000 included within its provision for income taxes.  This charge relates to the Company's determination that a full valuation allowance against its deferred tax assets generated in the U.S and three of the Company's international subsidiaries was necessary.  Accounting rules require a reduction of the carrying amounts of deferred tax assets by a valuation allowance if, based on the available and objectively verifiable evidence, it is more likely than not that such assets will not be realized.  The existence of cumulative losses for a certain threshold period is a significant form of negative evidence used in the assessment.  If a cumulative loss threshold is met, the accounting rules indicate that forecasts of future profitability are generally not sufficient positive evidence to overcome the presumption that a valuation allowance is necessary.
