The $1.8 million increase in the Company’s allowance for doubtful accounts is principally due to potential collection difficulties resulting from bankruptcy filings by certain customers during the six months ended April 30, 2012. The associated charges are included in selling, general and administrative expenses in the Company’s Condensed Consolidated Statements of Operations for the six months ended April 30, 2012 and were partially offset by the reversal of certain forfeited amounts otherwise payable to such customers.

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 $9.4 million and $9.6 million as of April 30, 2012 and October 31, 2011, respectively. The total customer rebates and credits deducted within net sales for the six months ended April 30, 2012 and 2011 was $1.1 million and $4.4 million, respectively. The total customer rebates and credits deducted within net sales for the three months ended April 30, 2012 and 2011 was $ .7 million and $1.8 million, respectively. The decrease in customer rebates and credits principally reflects a reduction in the net sales volume of certain customers eligible for rebates as well as a reduction in associated rebate percentages.
