INCOME TAXES
INCOME TAXES	8. INCOME TAXES We are required to assess the available positive and negative evidence to estimate if sufficient future income will be generated to utilize deferred tax assets. A significant piece of negative evidence that we consider is cumulative losses (generally defined as losses before income taxes) incurred over the most recent three-year period. Such evidence limits our ability to consider other subjective evidence such as our projections for future growth. As of October 31, 2013 and 2012, cumulative losses were incurred over the applicable three-year period. Our valuation allowances totaled $93.2 million and $111.0 million as of October 31, 2013 and 2012, respectively. The valuation allowances were established due to the uncertainty of our ability to utilize certain federal, state and foreign net operating loss carryforwards in the future. The amount of the deferred tax asset considered realizable could be adjusted if negative evidence, such as three-year cumulative losses, no longer exists and additional consideration is given to our growth projections.
