To provide investors and others with additional information regarding Dropbox's results, we have disclosed the following non-GAAP financial measures: non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP operating expenses (including research and development, sales and marketing and general and administrative), non-GAAP income from operations, non-GAAP net income, free cash flow ("FCF") and non-GAAP diluted net income per share. Dropbox has provided a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure. Non-GAAP cost of revenue, gross profit, operating expenses, income from operations, and net income differs from GAAP in that it excludes stock-based compensation expense and employer payroll tax expense relating to the release of two-tier RSUs with respect to the three months ended March 31, 2018. Non-GAAP general and administrative expense also excludes expense related to a donation of common stock to the Dropbox Foundation with respect to the three months ended June 30, 2017. Non-GAAP net income also includes the income tax effect of these adjustments. FCF differs from GAAP net cash provided by operating activities in that it treats capital expenditures as a reduction to net cash provided by operating activities. Free cash flow margin is calculated as FCF divided by revenue. Non-GAAP diluted net income per share differs from GAAP diluted net loss per share in that the numerator utilizes the non-GAAP net income as described above, and the weighted-average shares used in the computation include certain shares that are excluded from the GAAP diluted net loss per share calculation because their effect would have been anti-dilutive.
Dropbox's management uses these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short and long-term operating plans, and to evaluate Dropbox's financial performance and the ability to generate cash from operations. Management believes these non-GAAP financial measures reflect Dropbox's ongoing business in a manner that allows for meaningful period-to-period comparisons and analysis of trends in Dropbox's business, as they exclude expenses that are not reflective of ongoing operating results. Management also believes that these non-GAAP financial measures provide useful supplemental information to investors and others in understanding and evaluating Dropbox's operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies.
We believe that the non-GAAP financial measures, non-GAAP cost of revenue, gross profit, operating expenses, income from operations, net income, and diluted net income per share are meaningful to investors because they help identify underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude.
We believe that FCF is an indicator of our liquidity over the long term, and provides useful information regarding cash provided by operating activities and cash used for investments in property and equipment required to maintain and grow our business. FCF is presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP. FCF has limitations as an analytical tool, and it should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by operating activities. Some of the limitations of FCF are that FCF does not reflect our future contractual commitments, excludes investments made to acquire assets under capital leases, includes capital expenditures related to our new corporate headquarters, and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure.
The use of non-GAAP cost of revenue, gross profit, operating expenses, income from operations, net income, free cash flow, and diluted net income per share measures has certain limitations as they do not reflect all items of income, expense, and cash expenditures, as applicable, that affect Dropbox's operations. Dropbox compensates for these limitations by reconciling the non-GAAP financial measures to the most comparable GAAP financial measures. Additionally, we have provided supplemental disclosures in our reconciliation of net cash provided by operating activities to free cash flow to include capital expenditures related to our new corporate headquarters, net of tenant improvement allowances. These non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, measures prepared in accordance with GAAP. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore comparability may be limited. Management encourages investors and others to review Dropbox's financial information in its entirety and not rely on a single financial measure.
