Accounts Receivable Securitization Program [Abstract]
Accounts Receivable Securitization Program	(8) Accounts Receivable Securitization Program We and a group of our U.S. subsidiaries maintain an accounts receivable securitization program with a bank and an issuer of commercial paper administered by the bank. As of March 31, 2012, the maximum purchase limit for receivable interests was $125 million, subject to the availability limits described below. The amounts available from time to time under the program may be less than $125 million due to a number of factors, including but not limited to our credit ratings, trade receivable balances, the creditworthiness of our customers and our receivables collection experience. During 2012, the level of eligible assets available under the program was lower than $125 million primarily due to our current credit ratings. As a result, the amount available to us under the program was $93 million at March 31, 2012. Although we do not believe that these restrictive provisions presently materially restrict our operations, if an additional event occurs that triggers one of these restrictive provisions, we could experience a further decline in the amounts available to us under the program or termination of the program. As of March 31, 2012 and December 31, 2011, we had no amounts outstanding under this program, and we did not utilize this program during 2012. The program is scheduled to expire in December 2012. We intend to extend the receivables program prior to the expiration date. Under limited circumstances, the bank and the issuer of commercial paper can end purchases of receivables interests before the above dates. A failure to comply with interest coverage, debt leverage or various other ratios related to our receivables collection experience could result in termination of the receivables program. We were in compliance with these ratios at March 31, 2012 and December 31, 2011. Any transfers of ownership interests in receivables under this program are considered secured borrowings and will be recorded as liabilities on our condensed consolidated balance sheets. Program fees on any outstanding borrowings under this program are included in interest expense, and the costs related to commitment fees on the unused portion of this program are included in other expense, net, on our condensed consolidated statements of operations.
