Extreme considers free cash flow to be useful information for management and investors regarding the amount of cash generated by the business after the purchases of property, equipment and capitalized software development costs, which can then be used to, among other things, invest in Extreme's business, make strategic acquisitions, and strengthen the balance sheet. A limitation of the utility of this non-GAAP free cash flow metric as a measure of financial performance is that it does not represent the total increase or decrease in the Company's cash balance for the period. The following table shows non-GAAP free cash flow calculation (in millions): SaaS ARR: Extreme uses SaaS annual recurring revenue ("SaaS ARR") to identify the annual recurring revenue of ExtremeCloud IQ and other subscription revenue, based on the annualized value of quarterly subscription revenue and term-based licenses.
