During the quarter ended February 28, 2015, the Company recorded aggregate out of period corrections of $0.4 million, net of tax, which negatively impacted net income (loss) in the period. These corrections were primarily associated with research and development expense that should have been recorded in the first half of fiscal 2015. The Company has determined that these adjustments were not material to any prior annual or interim periods.
