With that said, I'm going to turn the call over to John to discuss our financial results, and then Jim will address our end markets and overall business strategy. Here is John Hohener. John W. Hohener Thank you, Terri. Net sales for the quarter ended July 1, 2012, were a record $259.2 million, up 4% sequentially from the $249.3 million and up 20% from the year-ago quarter of $216.7 million. Our non-GAAP gross margin was 56.2%, a sequential increase of 120 basis points and at the top of our guidance. This was driven by increased revenue, focused on new high-margin products and realization of operational synergies. We expect our non-GAAP gross margin to increase between 30 and 70 basis points next quarter, driven by continued improvement in manufacturing efficiencies and product absorption.
Our GAAP gross margin, which incorporates only noncash purchase accounting adjustments from our recent acquisitions, was 55.8%, a sequential increase of 290 basis points. In Q4, we don't expect any further noncash purchase accounting adjustments. This quarter, non-GAAP selling, general and administrative expenses were $41 million or 15.8% of sales compared to $40 million or 16% of sales in the prior quarter and compared to $37.3 million or 17.2% of sales reported a year ago. For the next quarter, we expect total SG&A to decrease slightly as a percentage of revenue.Research and development costs were $44 million or 17% of sales compared to $42.2 million or 16.9% of sales in the prior quarter and compared to $29.6 million or 13.6% of sales reported a year ago. The increase compared to prior year was due primarily in our investment of new product development. For the next quarter, we expect total R&D to decrease slightly as a percentage of revenue. Our non-GAAP operating income was $60.7 million or 23.4% of sales compared to $54.9 million or 22% of sales in the second quarter and $56.8 million or 26.2% recorded last year. We recorded $8.8 million in non-GAAP interest and other expense compared to $10.1 million last quarter, reflecting a full quarter's impact from the refinancing we completed last quarter. In addition, subsequent to our quarter end, we paid down $30 million of our term debt. This pay-down will allow us to see a decrease in interest and other expense of approximately $200,000 next quarter. Non-GAAP net income was $48.3 million or $0.55 per diluted share compared to $40.3 million or $0.46 per diluted share last quarter, an increase of 20%, and $42 million or $0.49 per diluted share reported a year ago. Our non-GAAP effective tax rate for the quarter was 7%, reflecting ongoing improvements in our tax structure. We expect this tax rate will continue next quarter.
