Gross margin was 49.9% in the reported quarter compared to 49.7% in the year ago quarter. The rise in gross margin was due to improved store shrink and lower supply costs, partially offset by augmented promotional activity. SG&A expenses for the quarter went up 2.3% to $559.7 million or 38.3% of sales from $546.9 million or 36.9% in the year ago quarter. The increase in SG&A expenses was attributable to a shift in expenses to the reported quarter along with lower sales volume. Operating income went down 10.4% to $169.2 million or 11.6% of sales in the quarter from $188.9 million or 12.8% of sales in the year-ago quarter. The decline was driven by a shift in SG&A expenses to the reported quarter, partially offset by lower incentive compensation expenses. Store Opening During the second quarter, Advance Auto Parts opened 10 new stores, including 3 Autopart International stores. During the first half of 2012, the company opened 35 stores, including 6 Autopart International stores.
