Non-GAAP Financial Measures
We have provided in this release financial information that has not been prepared in accordance with Generally Accepted Accounting Principles (GAAP). We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating our ongoing operational performance. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with other companies in our industry, many of which present similar non-GAAP financial measures to investors.
Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures below. As previously mentioned, a reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.
Billings. We define billings as revenue recognized plus the change in deferred revenue from the beginning to the end of the period. We consider billings to be a useful metric for management and investors because billings drive deferred revenue, which is an important indicator of the health and visibility of our business, and has historically represented a majority of the quarterly revenue that we recognize. There are a number of limitations related to the use of billings versus revenue calculated in accordance with GAAP. First, billings include amounts that have not yet been recognized as revenue. Second, we may calculate billings in a manner that is different from peer companies that report similar financial measures. Management compensates for these limitations by providing specific information regarding GAAP revenue and evaluating billings together with revenues calculated in accordance with GAAP.
Free cash flow. We define free cash flow as net cash provided by operating activities minus capital expenditures. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the acquisition of property and equipment, can be used for strategic opportunities, including investing in our business, making strategic acquisitions, and strengthening the balance sheet. Analysis of free cash flow facilitates management's comparisons of our operating results to competitors' operating results. A limitation of using free cash flow versus the GAAP measure of net cash provided by operating activities as a means for evaluating the Company is that free cash flow does not represent the total increase or decrease in the cash balance from operations for the period because it excludes cash used for capital expenditures. Management compensates for this limitation by providing information about our capital expenditures on the face of the cash flow statement and under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" in our most recent Quarterly Report on Form 10-Q and Annual Report on Form 10-K.
Non-GAAP operating income and operating margin. We define non-GAAP operating income as operating income plus stock-based compensation reduced by the income from payments we received from a patent settlement. Non-GAAP operating margin is defined as non-GAAP operating income divided by revenue. We consider these non-GAAP financial measures to be useful metrics for management and investors because they exclude the effect of stock-based compensation expense and patent settlement related income so that our management and investors can compare our recurring core business operating results over multiple periods. There are a number of limitations related to the use of non-GAAP operating income versus operating income calculated in accordance with GAAP. First, non-GAAP operating income excludes stock-based compensation expense. Stock-based compensation has been and will continue to be for the foreseeable future a significant recurring expense in our business. Second, stock-based compensation is an important part of our employees' compensation and impacts their performance. Third, the components of the costs that we exclude in our calculation of non-GAAP operating income may differ from the components that our peer companies exclude when they report their non-GAAP results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP operating income and evaluating non-GAAP operating income together with operating income calculated in accordance with GAAP.
Non-GAAP net income and diluted net income per share. We define non-GAAP net income as net income plus stock-based compensation expense reduced by the income from payments we received from a patent settlement, less the related tax effects. We define non-GAAP diluted net income per share as non-GAAP net income divided by the weighted-average diluted shares outstanding. We consider these non-GAAP financial measures to be useful metrics for management and investors for the same reasons that we use non-GAAP operating income and non-GAAP operating margin. However, in order to provide a complete picture of our recurring core business operating results, we exclude from non-GAAP net income and non-GAAP diluted net income per share, the tax effects associated with stock-based compensation and the patent settlement. We believe the effective tax rates we used are reasonable estimates of long-term normalized tax rates under our global operating structure. The same limitations described above regarding our use of non-GAAP operating income and non-GAAP operating margin apply to our use of non-GAAP net income and non-GAAP diluted net income per share. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income and non-GAAP diluted net income per share and evaluating non-GAAP net income and non-GAAP diluted net income per share together with net income and diluted net income per share calculated in accordance with GAAP.
