Accounts Receivable Securitization Programs	Note 8 Accounts Receivable Securitization Programs U.S. Accounts Receivable Securitization Program We and a group of our U.S. operating subsidiaries maintain an accounts receivable securitization program under which they sell eligible U.S. accounts receivable to an indirectly wholly-owned subsidiary that was formed for the sole purpose of entering into this program. The wholly-owned subsidiary in turn may sell an undivided fractional ownership interest in these receivables with two banks and issuers of commercial paper administered by these banks. The wholly-owned subsidiary retains the receivables it purchases from the operating subsidiaries. Any transfers of fractional ownership interests of receivables under the U.S. receivables securitization program to the two banks and issuers of commercial paper administered by these banks are considered secured borrowings with pledge of collateral and will be classified as short-term borrowings on our condensed consolidated balance sheet. The net trade receivables that served as collateral for these borrowings are reclassified from trade receivables, net to prepaid expenses and other current assets on the condensed consolidated balance sheet. As of March 31, 2015, the maximum purchase limit for receivable interests was $100 million, subject to the availability limits described below. The amounts available from time to time under this program may be less than $100 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 three months ended March 31, 2015, the level of eligible assets available under the program was lower than $100 million primarily due to certain required reserves against our receivables. As a result, the amount available to us under the program was $75 million at March 31, 2015. Although we do not believe restrictions under this program 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. This program expires annually in September and is renewable. The program was renewed in September 2014 for an additional year and the program size was reduced from $125 million to $100 million. European Accounts Receivables Securitization Program We and a group of our European subsidiaries maintain an accounts receivable securitization program with a special purpose vehicle, or SPV, two banks and issuers of commercial paper administered by these banks. The European program is structured to be a securitization of certain trade receivables that are originated by certain of our European subsidiaries. We do not have an equity interest in the SPV. However, since we are considered the primary beneficiary of the SPV, it meets the criteria to be classified as a variable interest entity and is included in our condensed consolidated financial statements. Any activity between the participating subsidiaries and the SPV is eliminated in consolidation. The SPV borrows funds from the banks to fund its acquisition of the receivables and provides the banks with a first priority perfected security interest in the accounts receivable. Loans from the banks to the SPV will be classified as short-term borrowings on our condensed consolidated balance sheet. The net trade receivables that served as collateral for these borrowings are reclassified from trade receivables, net to prepaid expenses and other current assets on the condensed consolidated balance sheet. As of March 31, 2015, the maximum purchase limit for receivable interests was €110 million, ($120 million equivalent at March 31, 2015) subject to availability limits. The terms and provisions of this program are similar to our U.S.-program discussed above. As of March 31, 2015, the amount available under this program was €99 million ($108 million equivalent as of March 31, 2015). This program expires annually in February and is renewable. The program was renewed in February 2015 and the maximum purchase limit was raised to €110 million. Utilization of Our Accounts Receivable Securitization Programs At March 31, 2015, there were no borrowings outstanding under our U.S. program or European program. We continue to service the trade receivables supporting the programs, and the banks are permitted to re-pledge this collateral. Total interest expense related to the use of these programs was less than $1 million for the three months ended March 31, 2015. Under limited circumstances, the banks and the issuers of commercial paper can end purchases of receivables interests before the above expiration 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 programs. We were in compliance with these ratios at March 31, 2015. As of December 31, 2014, the total amount of borrowings under our U.S. program was $36 million and there were no amounts outstanding under the European program.

Note 8 Accounts Receivable Securitization Programs

U.S. Accounts Receivable Securitization Program

We and a group of our U.S. operating subsidiaries maintain an accounts receivable securitization program under which they sell eligible U.S. accounts receivable to an indirectly wholly-owned subsidiary that was formed for the sole purpose of entering into this program. The wholly-owned subsidiary in turn may sell an undivided fractional ownership interest in these receivables with two banks and issuers of commercial paper administered by these banks. The wholly-owned subsidiary retains the receivables it purchases from the operating subsidiaries. Any transfers of fractional ownership interests of receivables under the U.S. receivables securitization program to the two banks and issuers of commercial paper administered by these banks are considered secured borrowings with pledge of collateral and will be classified as short-term borrowings on our condensed consolidated balance sheet. The net trade receivables that served as collateral for these borrowings are reclassified from trade receivables, net to prepaid expenses and other current assets on the condensed consolidated balance sheet.

As of March 31, 2015, the maximum purchase limit for receivable interests was $100 million, subject to the availability limits described below.

The amounts available from time to time under this program may be less than $100 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.

Although we do not believe restrictions under this program 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.

This program expires annually in September and is renewable. The program was renewed in September 2014 for an additional year and the program size was reduced from $125 million to $100 million.

European Accounts Receivables Securitization Program

We and a group of our European subsidiaries maintain an accounts receivable securitization program with a special purpose vehicle, or SPV, two banks and issuers of commercial paper administered by these banks. The European program is structured to be a securitization of certain trade receivables that are originated by certain of our European subsidiaries. We do not have an equity interest in the SPV. However, since we are considered the primary beneficiary of the SPV, it meets the criteria to be classified as a variable interest entity and is included in our condensed consolidated financial statements. Any activity between the participating subsidiaries and the SPV is eliminated in consolidation. The SPV borrows funds from the banks to fund its acquisition of the receivables and provides the banks with a first priority perfected security interest in the accounts receivable. Loans from the banks to the SPV will be classified as short-term borrowings on our condensed consolidated balance sheet. The net trade receivables that served as collateral for these borrowings are reclassified from trade receivables, net to prepaid expenses and other current assets on the condensed consolidated balance sheet.

As of March 31, 2015, the maximum purchase limit for receivable interests was €110 million, ($120 million equivalent at March 31, 2015) subject to availability limits.
