Trade Receivables Factoring Facility

In April 2010, the Company entered into a trade receivables factoring facility with a financial institution to sell certain of its trade receivables from customers with limited, non-credit related, recourse provisions. The sale of receivables eliminates the credit exposure of the Company in relation to these receivables. The Company pays facility administration fees to the financial institution on a quarterly basis. Under the terms of the factoring agreement, the maximum available amount of the factoring facility outstanding at any one time is $50.0 million, which is subject to change based on the financial institution's approval. During the three and nine months ended July 30, 2011, $20.6 million and $50.5 million, respectively, of trade receivables were sold under the terms of the factoring facility. During the three and nine months ended July 31, 2010, $17.9 million and $37.3 million, respectively, of trade receivables were sold under the terms of the factoring facility. Sales of trade receivables are recorded as a reduction of trade accounts receivable. The discounts on the sale of receivables for the three and nine months ended July 30, 2011 and the three and nine months ended July 31, 2010 were immaterial and are included in "Interest and other income (loss), net" on the Condensed Consolidated Statements of Income. Facility administration fees for the three and nine months ended July 30, 2011 and the three and nine months ended July 31, 2010 were immaterial and are included in "General and administrative expenses" on the Condensed Consolidated Statements of Income.
