Appendix A

Explanation of Non-GAAP Measures

Objective of non-GAAP measures: We believe our presentation of non-GAAP financial measures, when taken together with corresponding GAAP financial measures, provides meaningful supplemental information regarding the Company’s operating performance for the reasons discussed below. Our management team uses these non-GAAP financial measures in assessing Symantec’s performance, as well as in planning and forecasting future periods. Due to the importance of these measures in managing the business, we use non-GAAP measures in the evaluation of management’s compensation. These non-GAAP financial measures are not computed according to GAAP and the methods we use to compute them may differ from the methods used by other companies. Non-GAAP financial measures are supplemental and should not be considered a substitute for financial information presented in accordance with GAAP and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP.

Contract liabilities adjustment: Our non-GAAP net revenues eliminate the impact of contract liabilities purchase accounting adjustments required by GAAP. GAAP requires an adjustment to the liability for acquired contract liabilities such that the liability approximates how much we, the acquirer, would have to pay a third party to assume the liability. We believe that eliminating the impact of this adjustment improves the comparability of revenues between periods. Also, although the adjustment amounts will never be recognized in our GAAP financial statements, we do not expect the acquisitions to affect the future renewal rates of revenues excluded by the adjustments. In addition, our management uses non-GAAP net revenues, adjusted for the impact of purchase accounting adjustments to assess our operating performance and overall revenue trends. Nevertheless, non-GAAP net revenues has limitations as an analytical tool and should not be considered in isolation or as a substitute for GAAP net revenues. We believe these adjustments are useful to investors as an additional means to reflect revenue trends of our business. However, other companies in our industry may not calculate these measures in the same manner which may limit their usefulness for comparative purposes.

Inventory fair value adjustment: Purchase accounting requires us to measure acquired inventory at fair value. The fair value of inventory reflects the acquired company’s cost of manufacturing plus a portion of the expected profit margin. These non-GAAP adjustments to our cost of revenues exclude the expected profit margin component that is recorded under purchase accounting associated with our acquisitions. We believe the adjustments are useful to investors as an additional means to reflect cost of revenues and gross margin trends of our business.

Stock-based compensation: This consists of expenses for employee restricted stock units, performance based awards, bonus share programs, stock options and our employee stock purchase plan, determined in accordance with GAAP. We evaluate our performance both with and without these measures because stock-based compensation is a non-cash expense and can vary significantly over time based on the timing, size, nature and design of the awards granted, and is influenced in part by certain factors that are generally beyond our control, such as the volatility of the market value of our common stock. In addition, for comparability purposes, we believe it is useful to provide a non-GAAP financial measure that excludes stock-based compensation to facilitate the comparison of our results to those of other companies in our industry.

Amortization of intangible assets: Amortization of intangible assets consists of amortization of acquisition-related intangibles assets such as developed technology, customer relationships and trade names acquired in connection with business combinations. We record charges relating to the amortization of these intangibles within both cost of revenues and operating expenses in our GAAP financial statements. Under purchase accounting, we are required to allocate a portion of the purchase price to intangible assets acquired and amortize this amount over the estimated useful lives of the acquired intangible assets. However, the purchase price allocated to these assets is not necessarily reflective of the cost we would incur to internally develop the intangible asset. Further, amortization charges for our acquired intangible assets are inconsistent in size and are significantly impacted by the timing and valuation of our acquisitions. We eliminate these charges from our non-GAAP operating results to facilitate an evaluation of our current operating performance and provide better comparability to our past operating performance.

Restructuring, transition and other costs: Restructuring charges are costs associated with a formal restructuring plan and are primarily related to employee severance and benefit arrangements. Other charges include facilities and other exit and disposal costs, including asset write-offs. Transition costs are associated with formal discrete strategic information technology initiatives and primarily consist of consulting charges associated with our enterprise resource planning and supporting systems and costs to automate business processes. In addition, transition costs include expenses associated with our divestitures. We exclude restructuring, transition and other costs from our non-GAAP results as we believe that these costs are incremental to core activities that arise in the ordinary course of our business and do not reflect our current operating performance, and that excluding these charges facilitates a more meaningful evaluation of our current operating performance and comparisons to our past operating performance.

Acquisition-related costs: These represent the transaction and business integration costs related to significant acquisitions that are charged to operating expense in our GAAP financial statements. These costs include incremental expenses incurred to affect these business combinations such as advisory, legal, accounting, valuation, and other professional or consulting fees. We exclude these cost from our non-GAAP results as they have no direct correlation to the operation of our business, and because we believe that the non-GAAP financial measures excluding these costs provide meaningful supplemental information regarding the spending trends of our business. In addition, these costs vary, depending on the size and complexity of the acquisitions, and are not indicative of costs of future acquisitions.

Litigation settlement: We may periodically incur charges or benefits related to litigation settlements. We exclude these charges and benefits when associated with a significant settlement because we do not believe they are reflective of ongoing business and operating results.

Non-cash interest expense and amortization of debt issuance costs: In accordance with GAAP, we separately account for the value of the conversion feature on our convertible notes as a debt discount that reflects our assumed non-convertible debt borrowing rates. We amortize the discount and debt issuance costs over the term of the related debt. We exclude the difference between the imputed interest expense, which includes the amortization of the conversion feature and of the issuance costs, and the coupon interest payments because we believe that excluding these costs provides meaningful supplemental information regarding the cash cost of our convertible debt and enhance investors’ ability to view the Company’s results from management’s perspective.

Gain on divestitures: We periodically recognize gains on divestitures, including in fiscal 2018 related to our WSS and PKI solutions. We have excluded these gains for purposes of calculating our non-GAAP results. We believe making these adjustments facilitates a better evaluation of our current operating performance and comparisons to past operating results.

Gain (loss) from equity interest: We record gains or losses in equity method investments representing net income or loss attributable to our noncontrolling interest in companies over which we have limited control and visibility. We exclude such gains and losses in full because we lack control over the operations of the investee and the related gains and losses are not indicative of our ongoing core results.

Income tax effects and adjustments: Prior to the third quarter of fiscal 2018, we used a projected long-term non-GAAP tax rate that reflected the elimination of the effects of the non-GAAP adjustments to our operating results described above and significant discrete items, as well as certain unique GAAP reporting requirements under discontinued operations as a result of the sale of Veritas in order to provide better consistency across the interim financial reporting periods. Starting with the third quarter of fiscal 2018, as a result of U.S. tax reform, we use a non-GAAP tax rate that excludes (1) the discrete impacts of changes in tax legislation, (2) most other significant discrete items, (3) certain unique GAAP reporting requirements under discontinued operations and (4) the income tax effects of the non-GAAP adjustment to our operating results described above. We believe making these adjustments facilitates a better evaluation of our current operating performance and comparisons to past operating results. Our tax rate is subject to change for a variety of reasons, such as significant changes in the geographic earnings mix due to acquisition and divestiture activities or fundamental tax law changes in major jurisdictions where we operate.

Discontinued operations: In August 2015, we entered into a definitive agreement to sell the assets of our information management business (“Veritas”) to Carlyle. The transaction closed on January 29, 2016. The results of Veritas are presented as discontinued operations in our Consolidated Statements of Operations and thus have been excluded from non-GAAP net income and segment results for all reported periods.

Diluted GAAP and non-GAAP weighted-average shares outstanding: Diluted GAAP and non-GAAP weighted-average shares outstanding are the same, except in periods that there is a GAAP loss from continuing operations. In accordance with GAAP, we do not present dilution for GAAP in periods in which there is a loss from continuing operations. However, if there is non-GAAP net income, we present dilution for non-GAAP weighted-average shares outstanding in an amount equal to the dilution that would have been presented had there been GAAP income from continuing operations for the period.

Implied billings: We define implied billings as total revenue plus the change in adjusted contract liabilities. The change in contract liabilities excludes contract liabilities acquired or divested during the period as well as the change in contract liabilities related to discontinued operations that does not amortize to revenue from continuing operations. We consider implied billings to be a useful metric for management and investors because it facilitates an analysis of changes in contract liabilities balances that are an indicator of the health and visibility of our business. There are several limitations related to the use of implied billings versus revenue calculated in accordance with GAAP. First, implied billings include amounts that have not yet been recognized as revenue. Second, our calculation of implied billings may be different from other companies in our industry, some of which may not use implied billings, may calculate implied billings differently, may have different implied billing frequencies, or may use other financial measures to evaluate their performance, all of which could reduce the usefulness of implied billings as a comparative measure. We compensate for these limitations by providing specific information regarding GAAP revenue and evaluating implied billings together with revenue calculated in accordance with GAAP.
