Notes to our Non-GAAP Financial Measures

Revenue excluding Mortgage-related and eMarketing revenue is a Non-GAAP financial measure and is intended to supplement investors' understanding of our core business activities, unaffected by the fluctuations of the mortgage industry and the performance of our eMarketing business. Revenue excluding Mortgage-related and eMarketing revenue is useful to management and investors for comparative purposes.

We calculate free cash flow by subtracting capital-related expenditures from cash provided by operations. Free cash flow is useful to management and the Company's investors in measuring the cash generated by the Company that is available to be used for business and strategic initiatives. Free cash flow is not a measurement of liquidity under GAAP and should not be considered as an alternative to cash flows from operating activities as a measure of liquidity. In addition, our calculation of free cash flow may be different from the calculation used by other companies and therefore, comparability may be limited.
