(1) Net revenues, gross margin, net loss from continuing operations and net loss for the period from April 20, 2011 through July 1, 2011 have been adjusted from the amounts reported in the unaudited consolidated statements of operations on Form 10-Q for the quarterly period ended July 1, 2011. The increase in net revenue of $27,000 is related to a purchase price adjustment for customer rebate reserves. The decrease in gross margin is the net effect of the customer rebate reserve adjustment, a $73,000 decrease related to a purchase price adjustment for accrued royalties and $43,000 increase related to a purchase price adjustment for replacement award liability. The decrease in net loss from continuing operations is due to the net effects of the customer rebate reserve and accrued royalty adjustments, a $69,000 decrease related to a purchase price adjustment for electronic design tool amortization, a $0.3 million increase related to a purchase price adjustment for replacement award liability and a $2.5 million decrease due to changes in deferred tax liability determined as a result of purchase accounting revisions. The decrease in net loss is the sum of all the above adjustments.
