* Due to rounding, amounts may not add.
We currently operate in 20 states and are subject to various state tax jurisdictions. We estimate our state tax liability based upon the individual taxing authorities’ regulations, estimates of income by taxing jurisdiction, and our ability to utilize certain tax-saving strategies. Based on our estimate of the allocation of income or loss among the various taxing jurisdictions and changes in tax regulations and their impact on our tax strategies, we estimate our rate for the full fiscal year for state income taxes at 7.2% and 6.5% for fiscal 2014 and 2013, respectively.
For state tax purposes, due to past and projected losses in certain jurisdictions where we do not have carryback potential and/or cannot sufficiently forecast future taxable income, we have recognized net cumulative valuation allowances against our state deferred tax assets of $53.1 million and $55.7 million as of July 31, 2014 and October 31, 2013, respectively.
