Use and economic substance of non-GAAP financial measures used by Hewlett Packard Enterprise

Revenue on a constant currency basis assumes no change in the foreign exchange rate from the prior-year period. Non-GAAP operating expenses, non-GAAP operating profit, and non-GAAP operating margin are defined to exclude any charges relating to the amortization of intangible assets, restructuring charges, charges relating to the separation transactions, transformation costs, disaster charges and acquisition, disposition and other related charges. Non-GAAP net earnings from continuing operations and non-GAAP diluted net earnings per share from continuing operations consist of net earnings or diluted net earnings per share excluding those same charges, as well as an adjustment to earnings in equity interests, non-service net periodic benefit credit, tax indemnification adjustments, income tax valuation allowances and separation taxes, the impact of U.S. tax reform and excess tax benefit from stock-based compensation. Non-GAAP net earnings from discontinued operations and non-GAAP diluted net earnings per share from discontinued operations consist of net earnings from discontinued operations or diluted net earnings per share from discontinued operations excluding those same charges, as applicable to discontinued operations. In addition, non-GAAP net earnings from continuing operations, non-GAAP net earnings from discontinued operations, non-GAAP diluted net earnings per share from continuing operations and non-GAAP diluted net earnings per share from discontinued operations are adjusted by the amount of additional taxes or tax benefits associated with each non-GAAP item.

Hewlett Packard Enterprise’s management uses these non-GAAP financial measures for purposes of evaluating Hewlett Packard Enterprise’s historical and prospective financial performance, as well as Hewlett Packard Enterprise’s performance relative to its competitors. Hewlett Packard Enterprise’s management also uses these non-GAAP measures to further its own understanding of Hewlett Packard Enterprise’s segment operating performance. Hewlett Packard Enterprise believes that excluding the items mentioned above from these non-GAAP financial measures allows Hewlett Packard Enterprise’s management to better understand Hewlett Packard Enterprise’s consolidated financial performance in relation to the operating results of Hewlett Packard Enterprise’s segments, as Hewlett Packard Enterprise’s management does not believe that the excluded items are reflective of ongoing operating results. More specifically, Hewlett Packard Enterprise’s management excludes each of those items mentioned above for the following reasons:

• Hewlett Packard Enterprise incurs charges relating to the amortization of intangible assets. Those charges are included in Hewlett Packard Enterprise’s GAAP earnings from operations, operating margin, net earnings and diluted net earnings per share. Such charges are significantly impacted by the timing and magnitude of Hewlett Packard Enterprise’s acquisitions and any related impairment charges. Consequently, Hewlett Packard Enterprise excludes these charges for purposes of calculating these non-GAAP measures to facilitate a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Restructuring charges are costs associated with a formal restructuring plan and are primarily related to (i) employee termination costs and benefits (ii) costs to vacate duplicative facilities and (iii) an accelerated employee stock compensation program. Hewlett Packard Enterprise excludes these restructuring costs (and any reversals of charges recorded in prior periods) for purposes of calculating these non-GAAP measures because it believes that these historical costs do not reflect expected future operating expenses and do not contribute to a meaningful evaluation of Hewlett Packard Enterprise’s current operating performance or comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Separation costs are expenses associated with HP Inc.’s (formerly known as “Hewlett-Packard Company” or “HP Co.”) separation into two independent publicly-traded companies and the spin-off and merger transactions of the Enterprise Services business with CSC ("Everett Transaction") and the Software business with Micro Focus (“Seattle Transaction”). The charges are primarily related to third-party consulting, contractor fees and other incremental costs incurred to complete the transactions. Hewlett Packard Enterprise excludes these separation costs for purposes of calculating these non-GAAP measures to facilitate a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Transformation costs represent net costs related to the HPE Next initiative and include restructuring charges, program design and execution costs, costs incurred to transform Hewlett Packard Enterprise's IT infrastructure and gains from the sale of real-estate identified as part of the initiative as well as any impairment charges on real- estate assets identified as part of the initiative. Hewlett Packard Enterprise believes that eliminating such expenses and gains for purposes of calculating these non-GAAP measures facilitates a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s past operating performance.
• Disaster charges represent costs related to the damages sustained as a result of Hurricane Harvey in Houston, Texas, which includes the deductible related to the Company's insurance program as well as an impairment of the Company's facilities. It also includes final insurance settlements received in connection with the damages sustained. Hewlett Packard Enterprise believes that eliminating these amounts for purposes of calculating non-GAAP operating profit facilitates a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Hewlett Packard Enterprise incurs costs related to its acquisitions, disposition and other related charges, most of which are treated as non-cash or non-capitalized expenses. The charges are direct expenses such as professional fees and retention costs, as well as non-cash adjustments to the fair value of certain acquired assets such as inventory. Charges may also include expenses associated with disposal activities including legal and arbitration settlements in connection with certain dispositions. Because non-cash or non-capitalized acquisition-related expenses are inconsistent in amount and frequency and are significantly impacted by the timing and nature of Hewlett Packard Enterprise’s acquisitions and divestitures, Hewlett Packard Enterprise believes that eliminating such expenses for purposes of calculating these non-GAAP measures facilitates a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s past operating performance.
• Adjustment to earnings from equity interests includes the amortization of the basis difference in relation to the H3C divestiture and the resulting equity method investment in H3C. Hewlett Packard Enterprise believes that eliminating this amount for purposes of calculating non-GAAP operating profit facilitates a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Non-service net periodic benefit credit includes certain market-related factors such as (i) interest cost, (ii) expected return on plan assets, (iii) amortization of prior plan amendments, (iv) amortized actuarial gains or losses, (v) the impacts of any plan settlements/curtailments and (vi) impacts from other market-related factors associated with Hewlett Packard Enterprise's defined benefit pension and post-retirement benefit plans. These market-driven retirement-related adjustments are primarily due to the change in pension plan assets and liabilities which are tied to financial market performance. Hewlett Packard Enterprise excludes these adjustments and considers them to be outside the operational performance of the business.
• Tax indemnification adjustments are related to changes in the indemnification positions between Hewlett Packard Enterprise and HP Inc., DXC and Micro Focus that are recorded by the Company as pre-tax income or expense and not considered tax expense. Hewlett Packard Enterprise excludes these income or charges and the associated tax impact for the purpose of calculating these non-GAAP measures to facilitate a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• Beginning the first quarter of fiscal 2019, the company utilizes a structural long-term projected non-GAAP tax rate in order to provide better consistency across the interim reporting periods and eliminates the effects of items such as changes in tax valuation allowance and tax effects of acquisitions and disposition related costs and transformation costs since each of these can vary in size and frequency. When projecting this long-term rate, the company evaluated a three-year financial projection that excludes the direct impact of the following non-cash items: amortization of purchased intangibles and adjustments related to equity method investments. The projected rate is not expected to change with the recently announced acquisition of Cray Inc. in fiscal 2020 and also assumes no incremental acquisitions in the three-year projection period, and considers other factors including the company’s expected tax structure, its tax positions in various jurisdictions and current impacts from key legislation implemented in major jurisdictions where the company operates. For fiscal 2019, the company will use a projected non-GAAP tax rate of 12%, which reflects currently available information, including the impact of the Tax Act and interpretations thereof, as well as other factors and assumptions. The non-GAAP tax rate could be subject to change for a variety of reasons, including the rapidly evolving global tax environment, significant changes in the company’s geographic earnings mix including due to acquisition activity, or other changes to the company’s strategy or business operations. The company will re-evaluate its long-term rate as appropriate. The company believes that making these adjustments facilitates a better evaluation of our current operating performance and comparisons to past operating results.
• For periods presented in fiscal 2018, valuation allowances and separation taxes represent tax amounts in connection with the spin-off of the enterprise services business, Everett SpinCo, Inc., and the software business, Seattle SpinCo, Inc. Since these charges do not represent ongoing expenses, Hewlett Packard Enterprise excludes these charges for the purpose of calculating these non-GAAP measures to facilitate a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• As a result of the U.S. tax reform, during the first quarter of fiscal 2018, Hewlett Packard Enterprise recorded an estimated tax benefit from the provisional application of the new tax rules including a lower federal tax rate to deferred tax assets and liabilities, partially offset by a provisional estimate for transition tax expense on accumulated non-U.S. undistributed earnings, and a benefit as a result of the liquidation of an insolvent non U.S. subsidiary. During subsequent quarters, the Company recorded adjustments under SAB118 (which was completed in the first quarter of fiscal 2019) in connection with U.S. tax reform primarily related to transition tax and valuation allowances on certain U.S. tax credits. Since these adjustments represent a one-time charge and do not represent ongoing expenses, Hewlett Packard Enterprise excludes the charge for the purpose of calculating these non-GAAP measures to facilitate a more meaningful evaluation of the Company’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
• During the first quarter of fiscal 2018, the Company adopted ASU 2016-09 on a prospective basis, except for the statement of cash flows for which the statement was retrospectively adopted for the prior comparative periods. This standard requires excess tax benefits or tax deficiencies associated with stock-based compensation to be recognized as a component of the provision for income taxes in the Statement of Earnings rather than additional paid-in capital in the Balance Sheet. Since the benefit or deficiency is the outcome of Hewlett Packard Enterprise’s stock price at the time an award is converted to a share of Hewlett Packard Enterprise’s stock, Hewlett Packard Enterprise excludes these benefits or deficiencies for the purpose of calculating these non-GAAP measures to facilitate a more meaningful evaluation of Hewlett Packard Enterprise’s current operating performance and comparisons to Hewlett Packard Enterprise’s operating performance in other periods.
