Q2 Fiscal 2024

→ Non-GAAP Financial Measures and Other Key Metrics To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use certain non-GAAP financial measures, as described below, to understand and evaluate our core operating performance. These non-GAAP financial measures, which may be different than similarly-titled measures used by other companies, are presented to enhance investors' overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We believe that these non-GAAP financial measures provide useful information about our financial performance, enhance the overall understanding of our past performance and future prospects, and allow for greater transparency with respect to important metrics used by our management for financial and operational decision-making. We present these non-GAAP measures to assist investors in seeing our financial performance using a management view, and because we believe that these measures provide an additional tool for investors to use in comparing our core financial performance over multiple periods with other companies in our industry. However, these non-GAAP measures are not intended to be considered in isolation from, a substitute for, or superior to our GAAP results. Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income and non-GAAP net income per share: We define these non-GAAP financial measures as the respective GAAP measures, excluding expenses related to stock-based compensation, employer payroll tax on employee stock transactions, amortization of acquisition-related intangibles, amortization of debt discount and issuance costs, fair value adjustments to strategic investments, executive transition costs, lease-related impairment and lease-related charges, restructuring and other related charges, as these costs are not reflective of ongoing operations and, as applicable, other special items. The amount of employer payroll tax-related items on employee stock transactions is dependent on our stock price and other factors that are beyond our control and do not correlate to the operation of the business. When evaluating the performance of our business and making operating plans, we do not consider these items (for example, when considering the impact of equity award grants, we place a greater emphasis on overall stockholder dilution rather than the accounting charges associated with such grants). We believe it is useful to exclude these expenses in order to better understand the long-term performance of our core business and to facilitate comparison of our results to those of peer companies and over multiple periods. In addition to these exclusions, we subtract an assumed provision for income taxes to calculate non-GAAP net income. We utilize a fixed long-term projected tax rate in our computation of the non-GAAP income tax provision to provide better consistency across the reporting periods. For fiscal 2023 and fiscal 2024, we have determined the projected non-GAAP tax rate to be 20%. Free cash flow: We define free cash flow as net cash provided by operating activities less purchases of property and equipment. We believe free cash flow is an important liquidity measure of the cash that is available (if any), after purchases of property and equipment, for operational expenses, investment in our business, and to make acquisitions. Free cash flow is useful to investors as a liquidity measure because it measures our ability to generate or use cash in excess of our capital investments in property and equipment. Once our business needs and obligations are met, cash can be used to maintain a strong balance sheet and invest in future growth. Billings: We define billings as total revenues plus the change in our contract liabilities and refund liability less contract assets and unbilled accounts receivable in a given period. Billings reflects sales to new customers plus subscription renewals and additional sales to existing customers. Only amounts invoiced to a customer in a given period are included in billings. We believe billings is a key metric to measure our periodic performance. Given that most of our customers pay in annual installments one year in advance, but we typically recognize a majority of the related revenue ratably over time, we use billings to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measure, please see "Reconciliation of GAAP to Non-GAAP Financial Measures" below.
