2008 through 2010 for which a previous tax benefit should not have been recorded, and the reversal of a $0.5 million deferred tax asset related to certain sharebased compensation expense. Net Income Net income was $40.8 million in fiscal 2012, which represented a decrease of 21.0%, or $10.8 million, from fiscal 2011. The decrease was primarily due to decreased sales volume coupled with a lower gross profit percentage, increased bad debt expense related to a customer bankruptcy filing, the expenses associated with our leveraged recapitalization with a special cash dividend, increased interest expense and a higher effective tax rate. decrease in gross profit as a percentage of revenue was primarily due to higher fixed manufacturing costs, the negative effects of foreign exchange rate changes, pricing impacts and the absence of a raw material supplier credit we recognized in the first quarter of fiscal 2010 related to our achieving a certain volume threshold in calendar 2009, partially offset by a higher-valued product mix. Research, Development and Technical Total research, development and technical expenses were $58.0 million in fiscal 2011, which represented an increase of 12.0%, or $6.2 million, from fiscal 2010. The increase was primarily due to $3.6 million in higher staffing-related costs, related to higher staffing levels and separation costs related to the transition of one of our executive officers, and $2.2 million in higher expenses for research and development materials. Year Ended September 30, 2011, Versus Year Ended September 30, 2010 Revenue Revenue was $445.4 million in fiscal 2011, which represented an increase of 9.1%, or $37.2 million, from fiscal 2010. The increase in revenue was driven by a $35.6 million increase in sales volume, a $5.5 million increase due to the effect of foreign exchange rate changes, and a $4.7 million increase due to a higher-priced product mix. These increases were partially offset by an $8.9 million decrease in revenue due to pricing impacts. The economic and industry growth that we saw during fiscal 2010 continued into fiscal 2011. However, we saw some softening of demand in the semiconductor industry in the second half of fiscal 2011 based on certain factors, including general uncertainty in the global economy and a modest correction of integrated circuit (IC) device inventory. Selling and Marketing Selling and marketing expenses were $29.8 million in fiscal 2011, which represented an increase of 10.7%, or $2.9 million, from fiscal 2010. The increase was primarily due to $1.3 million in higher staffing related costs, $0.6 million in higher travel-related costs and $0.4 million in higher miscellaneous selling expenses. General and Administrative General and administrative expenses were $45.9 million in fiscal 2011, which represented a decrease of 9.6%, or $4.9 million, from fiscal 2010. The decrease was primarily due to $6.8 million in lower professional fees, including costs to enforce our intellectual property, partially offset by $1.1 million in higher staffing-related costs and $0.6 million in higher depreciation expense. See Part I, Item 3 entitled “Legal Proceedings” and Note 16 of the Notes to the Consolidated Financial Statements for more information on the enforcement of our intellectual property. Cost of Goods Sold Total cost of goods sold was $231.3 million in fiscal 2011, which represented an increase of 13.0%, or $26.6 million, from fiscal 2010. The increase in cost of goods sold was primarily due to $17.8 million from increased sales volume due to increased demand for our products, a $9.5 million increase due to the effect of foreign exchange rate changes, a $6.9 million increase due to higher fixed manufacturing costs, a $1.8 million increase due to higher freight and packaging costs, a $1.3 million increase due to certain production variances and a $0.7 million increase due to higher sample costs. These increases were partially offset by an $11.5 million decrease in cost of goods sold due to a lower-cost product mix. Interest Expense Interest expense was $0.2 million in both fiscal 2011 and 2010, which primarily represented interest expense on our capital lease obligations. Other Income (Expense), Net Other expense was $1.3 million in fiscal 2011, compared to $0.5 million during fiscal 2010. The increase in other expense was primarily due to $1.1 million in foreign exchange effects, primarily related to changes in the exchange rate of the Japanese yen and the New Taiwan dollar to the U.S. dollar, net of the gains and losses incurred on forward foreign exchange contracts discussed in Note 10 of the Notes to the Consolidated Financial Statements. Gross Profit Our gross profit as a percentage of revenue was 48.1% in fiscal 2011 as compared to 49.9% for fiscal 2010. The 28
