Adjusted Income from Continuing Operations and Adjusted Diluted Earnings Per Share
In 2023, Adjusted income from continuing operations and adjusted diluted earnings per share will be modified to exclude the impact of LIFO inventory provision, net of tax and intangible asset amortization, net of tax because we do not consider these items to be directly related to the operating performance of our segments. LIFO inventory provision, net of tax is excluded to improve comparability with other companies in our industry who have not elected to use the LIFO inventory costing method. Intangible asset amortization, net of tax is excluded to improve comparability as the impact of such amortization can vary substantially from company to company depending upon the nature and extent of acquisitions and exclusion of this expense is consistent with the presentation of non-GAAP measures provided by other companies within our industry. Management believes that it is important for investors to understand that these intangible assets were recorded as part of purchase accounting and contribute to revenue generation. The 2023 outlook below reflects these modifications to our presentation of these non-GAAP financial measures.
