In managing Qorvo's business on a consolidated basis, management develops an annual operating plan, which is approved by our Board of Directors, using non-GAAP financial measures. In developing and monitoring performance against this plan, management considers the actual or potential impacts on these non-GAAP financial measures from actions taken to reduce costs with the goal of increasing gross margin and operating margin. In addition, management relies upon these non-GAAP financial measures to assess whether research and development efforts are at an appropriate level, and when making decisions about product spending, administrative budgets, and other operating expenses. Also, we believe that non-GAAP financial measures provide useful supplemental information to investors and enable investors to analyze the results of operations in the same way as management. We have chosen to provide this supplemental information to enable investors to perform additional comparisons of our operating results, to assess our liquidity and capital position and to analyze financial performance excluding the effect of expenses unrelated to operations, certain non-cash expenses and stock-based compensation expense, which may obscure trends in Qorvo's underlying performance.
We believe that these non-GAAP financial measures offer an additional view of Qorvo's operations that, when coupled with the GAAP results and the reconciliations to corresponding GAAP financial measures, provide a more complete understanding of Qorvo's results of operations and the factors and trends affecting Qorvo's business. However, these non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.
Our rationale for using these non-GAAP financial measures, as well as their impact on the presentation of Qorvo's operations, are outlined below:
Non-GAAP gross profit and gross margin. Non-GAAP gross profit and gross margin exclude amortization of intangible assets, stock-based compensation expense, restructuring related charges and certain non-cash expenses. We believe that exclusion of these costs in presenting non-GAAP gross profit and gross margin facilitates a useful evaluation of our historical performance and projected costs and the potential for realizing cost efficiencies.
We view amortization of acquisition-related intangible assets, such as the amortization of the cost associated with an acquired company’s research and development efforts, trade names, and customer relationships, as items arising from pre-acquisition activities, determined at the time of an acquisition, rather than ongoing costs of operating Qorvo’s business. While these intangible assets are continually evaluated for impairment, amortization of the cost of purchased intangible assets is a static expense, which is not typically affected by operations during any particular period. Although we exclude the amortization of purchased intangible assets from these non-GAAP financial measures, management believes that it is important for investors to understand that such intangible assets were recorded as part of purchase price accounting and contribute to revenue generation.
We believe that presentation of non-GAAP gross profit and gross margin and other non-GAAP financial measures that exclude the impact of stock-based compensation expense assists management and investors in evaluating the period-over-period performance of Qorvo's ongoing operations because (i) the expenses are non-cash in nature, and (ii) although the size of the grants is within our control, the amount of expense varies depending on factors such as short-term fluctuations in stock price volatility and prevailing interest rates, which can be unrelated to the operational performance of Qorvo during the period in which the expense is incurred and generally are outside the control of management. Moreover, we believe that the exclusion of stock-based compensation expense in presenting non-GAAP gross profit and gross margin and other non-GAAP financial measures is useful to investors to understand the impact of the expensing of stock-based compensation to Qorvo's gross profit and gross margins and other financial measures in comparison to prior periods. We also believe that the adjustments to profit and margin related to restructuring related charges and certain non-cash expenses do not constitute part of Qorvo's ongoing operations and therefore the exclusion of these items provides management and investors with better visibility into the actual revenue and actual costs required to generate revenues over time and facilitates a useful evaluation of our historical and projected performance. We believe disclosure of non-GAAP gross profit and gross margin has economic substance because the excluded expenses do not represent continuing cash expenditures and, as described above, we have little control over the timing and amount of the expenses in question.
For the three months ended July 2, 2022 and April 1, 2023, non-GAAP gross profit and gross margin also excluded charges associated with a long-term capacity reservation agreement. Unprecedented disruption resulting from measures taken in China to control the COVID-19 pandemic and the war in Ukraine negatively impacted demand for 5G handsets in China and EMEA within a short period of time. Due to these extraordinary circumstances, our demand was not expected to support the minimum purchase commitments under a long-term capacity reservation agreement with a foundry supplier which resulted in charges recorded in our cost of goods sold for the three months ended July 2, 2022. Subsequently, for the three months ended April 1, 2023, we elected to apply the remaining pre-paid refundable deposit against portions of monthly purchase commitments for the term of the amended agreement in lieu of ordering certain additional silicon wafers. This election was made to better align component inventory with the timing of the forecasted finished goods demand. This resulted in an impairment to the prepaid refundable deposit recorded in our cost of goods sold for the three months ended April 1, 2023. We believe these charges are not reflective of the performance of our ongoing business.
Non-GAAP operating expenses, operating income and operating margin. Non-GAAP operating expenses, operating income and operating margin exclude stock-based compensation expense, amortization of intangible assets, acquisition and integration related costs, gain or loss on assets, asset impairments, restructuring related charges, charges associated with a long-term capacity reservation agreement and certain non-cash expenses. We believe that presentation of a measure of operating expenses, operating income and operating margin that excludes amortization of intangible assets and stock-based compensation expense is useful to both management and investors for the same reasons as described above with respect to our use of non-GAAP gross profit and gross margin. We believe that acquisition and integration related costs, gain or loss on assets, asset impairments, restructuring related charges, charges associated with a long-term capacity reservation agreement and certain non-cash expenses do not constitute part of Qorvo's ongoing operations and therefore, the exclusion of these costs provides management and investors with better visibility into the actual costs required to generate revenues over time and facilitates a useful evaluation of our historical and projected performance. We believe disclosure of non-GAAP operating expenses, operating income and operating margin has economic substance because the excluded expenses are either unrelated to ongoing operations or do not represent current cash expenditures.
Non-GAAP net income and non-GAAP net income per diluted share. Non-GAAP net income and non-GAAP net income per diluted share exclude the effects of stock-based compensation expense, amortization of intangible assets, acquisition and integration related costs, gain or loss on assets, asset impairments, restructuring related charges, charges associated with a long-term capacity reservation agreement and certain non-cash expenses, gain or loss on investments, other expense (income) and also reflect an adjustment of income taxes. The income tax adjustment primarily represents the use of research and development tax credit carryforwards, deferred tax expense (benefit) items not affecting taxes payable, adjustments related to the deemed and actual repatriation of historical foreign earnings, non-cash expense (benefit) related to uncertain tax positions and other items unrelated to the current fiscal year or that are not indicative of our ongoing business operations. We believe that presentation of measures of net income and net income per diluted share that exclude these items is useful to both management and investors for the reasons described above with respect to non-GAAP gross profit and gross margin and non-GAAP operating expenses, operating income and operating margin. We believe disclosure of non-GAAP net income and non-GAAP net income per diluted share has economic substance because the excluded expenses are either unrelated to ongoing operations or do not represent current cash expenditures.
Free cash flow. Qorvo defines free cash flow as net cash provided by operating activities during the period minus property and equipment expenditures made during the period, and free cash flow margin is calculated as free cash flow as a percentage of revenue. We use free cash flow as a supplemental financial measure in our evaluation of liquidity and financial strength. Management believes that this measure is useful as an indicator of our ability to service our debt, meet other payment obligations and make strategic investments. Free cash flow should be considered in addition to, rather than as a substitute for, net income as a measure of our performance and net cash provided by operating activities as a measure of our liquidity. Additionally, our definition of free cash flow is limited, in that it does not represent residual cash flows available for discretionary expenditures due to the fact that the measure does not deduct the payments required for debt service and other contractual obligations. Therefore, we believe it is important to view free cash flow as a measure that provides supplemental information to our entire statement of cash flows.
