Accounts Receivable Securitization Program	9 Months Ended
Sep. 30, 2012
Accounts Receivable Securitization Program	(9) Accounts Receivable Securitization Program We and a group of our U.S. subsidiaries maintain an accounts receivable securitization program with two banks and issuers of commercial paper administered by these banks. As of September 30, 2012, the maximum purchase limit for receivable interests was $125 million, subject to the availability limits described below. The program, originally scheduled to mature in December 2012, was renewed in September 2012, and now matures in September 2013. 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. The amount available to us under the program was $118 million at September 30, 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 September 30, 2012 and December 31, 2011, we had no amounts outstanding under this program, and we did not utilize this program during 2012. Under limited circumstances, the banks and the issuers of commercial paper can end purchases of receivables interests before the above dates. A failure to comply with 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, 2012 and December 31, 2011.
