R&D investment increased to $34.2 million and SG&A expense was $32.2 million. Resulting GAAP operating income was 12.1 percent. Diluted GAAP earnings per share increased by 42 percent sequentially to 47 cents, due in part to a tax reserve release. The following non-GAAP results exclude the impact of stock compensation and other one-time items. Significant strength in the company’s Broad-based products improved the gross margin mix, resulting in gross margin of 61.3 percent for the quarter. R&D increased to $31.3 million due to a record quarter of new product activity, and SG&A increased slightly to $24.4 million. Operating income, therefore, was better than expected at 20.2 percent of revenue.

Reconciling charges are set forth in the financial measures table included below. The company ended the quarter with $323 million in cash, cash equivalents and investments due to continued healthy cash flow from operations.
