We use Adjusted gross billings of product and services as a supplemental measure of our performance to gain insight into the volume of business generated by our business, and to analyze the changes to our accounts receivable and accounts payable. Our use of Adjusted gross billings of product and services as analytical tools has limitations, and you should not consider them in isolation or as substitutes for analysis of our financial results as reported under U.S. GAAP.
