Accounts Receivable Securitization Program	9 Months Ended
Sep. 30, 2011
Accounts Receivable Securitization Program [Abstract]
Accounts Receivable Securitization Program	(5) 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 September 30, 2011, 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 the nine months ended September 30, 2011, 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 $89 million at September 30, 2011. 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 September 30, 2011 and December 31, 2010, we had no amounts outstanding under this program, and we did not utilize this program during the first nine months of 2011. The overall program is scheduled to expire in December 2012; however, the program includes a bank financing commitment that must be renewed annually. The bank financing commitment is scheduled to expire on December 2, 2011. We plan to seek an additional 364 day renewal of the bank commitment before its expiration. While the bank is not obligated to renew the bank financing commitment, we have negotiated annual renewals since the commencement of the program in 2001. 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 September 30, 2011 and December 31, 2010. During September 2011, we amended the program to remove a credit rating-based event of termination. 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. Also, the fees on outstanding borrowings under this program, if any, will be included in interest expense, and the costs of commitment fees on the unused portion of this program are included in other income (expense), net, on our condensed consolidated statements of operations.
