(10) Income Taxes

The Company did not recognize any consolidated income tax benefit (expense) for the three and six month periods ended October 31, 2015 and 2014. The Company has recorded a valuation allowance to reduce its net deferred tax asset to an amount that is more likely than not to be realized in future years. Accordingly, the benefit of the net operating loss that would have been recognized was offset by changes in the valuation allowance.

During the three and six months ended October 31, 2015, the Company had no material changes in uncertain tax positions.
