Reconciliation of Non-GAAP Financial Measures
June 30,
2007 2006 Change
Accounts receivable (in millions):
Accounts receivable, net $ 246.2 $ 233.8 $ 12.4
Retained interest in receivables sold, net 130.3 136.5 (6.2)
Accounts receivable sold 250.0 225.0 25.0
Total accounts receivable $ 626.5 $ 595.3 $ 31.2
Note: Retained interest in receivables sold represents the company's residual interest in receivables that
effectively form part of the collateral for the securitization. This retained interest is the amount in excess
of the balance of accounts receivables sold under the securitization program. The company believes it is
helpful to provide readers of its financial statements with total gross accounts receivable, which the
company regards as a more meaningful measure of accounts receivable that are used in the company's
operations.
