* Due to rounding, amounts may not add. The Company currently operates in 19 states and is subject to various state tax jurisdictions. The Company estimates its state tax liability based upon the individual taxing authorities’ regulations, estimates of income by taxing jurisdiction and the Company’s ability to utilize certain tax-saving strategies. Based on the Company’s estimate of the allocation of income or loss among the various taxing jurisdictions and changes in tax regulations and their impact on the Company’s tax strategies, the Company estimated its rate for state income taxes at 6.4% and 6.5% for fiscal 2013 and 2012, respectively. At October 31, 2012, the Company evaluated evidence related to the need for its deferred tax asset valuation allowances and determined that the valuation allowance on its federal deferred tax assets and certain state valuation allowances were no longer needed. Accordingly, in the fourth quarter of fiscal 2012, the Company reversed a valuation allowance in the amount of $394.7 million. For state tax purposes, due to past and projected losses in certain jurisdictions where the Company does not have carryback potential and/or cannot sufficiently forecast future taxable income, the Company has recognized net cumulative valuation allowances against its state deferred tax assets of $53.9 million and $57.0 million as of July 31, 2013 and October 31, 2012, respectively.
