Acquisition-related Items: We exclude the impact of certain items recorded in connection with business combinations from our non-GAAP financial measures that are either non-cash or not normal, recurring operating expenses due to their nature, variability of amounts and lack of predictability as to occurrence or timing. These amounts may include non-cash items such as the amortization of acquired intangible assets and amortization of items associated with fair value purchase accounting adjustments, including recognition of acquired deferred revenue (see Non-GAAP Revenue above). We also exclude other acquisition and integration costs associated with business acquisitions that are not normal recurring operating expenses, including amortization of amounts paid to redeem acquires’ unvested stock-based compensation awards, and legal, accounting and due diligence costs. We exclude these charges to facilitate a more meaningful evaluation of our current operating performance and comparisons to our past operating performance.

•

Share-based Compensation Expense: We exclude share-based compensation expense from our non-GAAP financial measures because share-based compensation expense can vary significantly from period to period based on the company’s share price, as well as the timing, size and nature of equity awards granted. Management believes the exclusion of this expense facilitates the ability of investors to compare the company’s operating results with those of other companies, many of which also exclude share-based compensation expense in determining their non-GAAP financial measures.

•

Goodwill Impairment charges: We exclude goodwill impairment charges from our non-GAAP financial measures, as such charges are non-recurring and do not reduce company's liquidity. In addition, the company's peer industry group companies may record impairment charges at different times, excluding such charges permits more accurate comparison of company's financial performance with those of its peers.

•

Restructuring and Related Costs: We exclude incremental expenses associated with restructuring initiatives, usually aimed at material changes in the business or cost structure. Such costs may include employee separation costs, asset impairments, facility-related costs, contract termination fees, and costs to move operations from one location to another. These activities can vary significantly from period to period based on the timing, size and nature of restructuring plans; therefore, we do not consider such costs to be normal, recurring operating expenses. We believe that these costs do not reflect expected future operating expenses and do not contribute to a meaningful evaluation of the company’s current operating performance or comparisons to our operating performance in other periods.

•

Northern California wildfire-related costs and Other Items: We exclude certain other significant income or expense items that may occur occasionally and are not normal, recurring, cash operating, from our non-GAAP financial measures. Such items are evaluated on an individual basis based on both quantitative and qualitative factors and generally represent items that we would not anticipate occurring as part of our normal business on a regular basis. While not all-inclusive, examples of certain other significant items excluded from non-GAAP financial measures would include net unrealized gains on equity investments still held, and significant non recurring events like litigation settlements, realized gains or losses associated with our employee benefit plans, costs related to unusual disaster like Northern California wildfires, gain on sale of assets and small divestitures, separation and related costs, etc.

•

Estimated Tax Rate: We utilize a consistent methodology for long-term projected non-GAAP tax rate. When projecting this long-term rate, we exclude any tax benefits or expenses that are not directly related to ongoing operations and which are either isolated or cannot be expected to occur again with any regularity or predictability. Additionally, we evaluate our current long-term projections, current tax structure and other factors, such as existing tax positions in various jurisdictions and key tax holidays in major jurisdictions where Keysight operates. This tax rate could change in the future for a variety of reasons, including but not limited to significant changes in geographic earnings mix including acquisition activity, or fundamental tax law changes in major jurisdictions where Keysight operates. The above reasons also limit our ability to reasonably estimate the future GAAP tax rate and provide a reconciliation of the expected non-GAAP earnings per share for the first fiscal quarter of 2020 to the GAAP equivalent.
