Reconciliation of Non-GAAP Measures

(Millions) (Unaudited)

Overview

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (referred to in this release as in accordance with "GAAP" or "reported" results). The Company also refers to and presents certain additional non-GAAP financial measures, within the meaning of Regulation G in accordance with the Securities Exchange Act of 1934. These measures are: adjusted operating income (loss), adjusted operating margin, adjusted income, net of tax and adjusted earnings per share (EPS). The Company has included reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP in the following tables.

The Company believes these non-GAAP financial measures provide useful supplemental information that enables investors to better compare the Company’s performance across periods. Management also uses these measures internally to assess the operating performance of its businesses, to assess performance for employee compensation, and to decide how to allocate resources. However, investors should not consider these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports in accordance with GAAP. The Company's non-GAAP measures include adjustments that reflect how management views its businesses, and may differ from similarly titled non-GAAP measures presented by other companies.

Adjusted Operating Income (Loss) and Adjusted Operating Margin

Adjusted operating income (loss) is calculated by excluding the impact of certain noteworthy items from the Company's GAAP operating income (loss). The following tables identify these noteworthy items and reconcile adjusted operating income (loss) to GAAP operating income (loss), on a consolidated and reportable segment basis, for the three and twelve month periods ended December 31, 2021 and 2020. The following tables also present adjusted operating margin. For the three and twelve months ended December 31, 2021 and 2020, adjusted operating margin is calculated by dividing the sum of adjusted operating income and identified intangible asset amortization by consolidated or segment adjusted revenue.

Adjusted income, net of tax is calculated as the Company's GAAP income from continuing operations, adjusted to reflect the after tax impact of the operating income adjustments in the preceding tables and the additional items listed below. Adjusted EPS is calculated by dividing the Company’s adjusted income, net of tax, by average number of shares outstanding-diluted for the relevant period. The following tables reconcile adjusted income, net of tax to GAAP income from continuing operations and adjusted EPS to GAAP EPS for the three and twelve month periods ended December 31, 2021 and 2020.
