We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our operating results because they exclude amounts that management and the board of directors do not consider part of core operating results when assessing the performance of the organization. We believe that inclusion of these non-GAAP financial measures provides consistency and comparability with past reports of financial results and provides consistency in calculations by outside analysts reviewing our results. Accordingly, we believe these non-GAAP financial measures are useful to investors in allowing for greater transparency of supplemental information used by management.
While we believe that these non-GAAP financial measures provide useful supplemental information, there are limitations associated with the use of these non-GAAP financial measures. These non-GAAP financial measures are not prepared in accordance with GAAP, do not reflect a comprehensive system of accounting and may not be completely comparable to similarly titled measures of other companies due to potential differences in the exact method of calculation between companies. Items such as share-based compensation expense; the amortization of acquired software and intangible assets; restructuring charges; advisory fees associated with certain shareholder actions and business transformation; and the related tax impacts of these items that are excluded from our non-GAAP financial measures can have a material impact on net earnings. As a result, these non-GAAP financial measures have limitations and should not be considered in isolation from, or as a substitute for, net earnings, cash flow from operations or other measures of performance prepared in accordance with GAAP. We compensate for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by reconciling the non-GAAP financial measures to their most comparable GAAP financial measure. Investors are encouraged to review the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures that are included elsewhere in this press release.
