Accrued Customer Rebates and Credits The aggregate amount of accrued customer rebates and credits included within accrued expenses and other current liabilities in the accompanying Condensed Consolidated Balance Sheets was $14.5 million and $10.8 million as of July 31, 2013 and October 31, 2012, respectively. The total customer rebates and credits deducted within net sales for the nine months ended July 31, 2013 and 2012 was $6.0 million and $2.1 million, respectively. The total customer rebates and credits deducted within net sales for the three months ended July 31, 2013 and 2012 was $2.5 million and $1.0 million, respectively. The increase in customer rebates and credits is principally due to the fact that the first nine months and third quarter of fiscal 2012 reflected a reduction in the net sales volume of certain customers eligible for rebates as well as a reduction in the associated rebate percentages.
