Non-GAAP Measure Description [Text Block] |
(6) | The company-selected measure is the ratio of operating cash flow to qualifying net income attained. Qualifying net income is tax affected adjusted operating income. Adjusted operating income is income before income taxes excluding (a) asset impairments, (b) amounts for performance share compensation, (c) amounts recorded for changes to the Company’s capital structure, and (d) amounts for amortization of debt discount. Adjusted operating income is reduced by (a) income taxes using the Company’s effective tax rate and (b) amounts included in the provision for income taxes due to the application of FASB Accounting Standards Update No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting to arrive at Qualifying Net Income.
