| Non-GAAP Measure Description [Text Block] | For purposes of this pay versus performance disclosure, adjusted EPS is calculated based on the Company’s adjusted earnings per share as used for external reporting purposes for the Covered Year (net of taxes), adjusted to exclude the effect of material changes in accounting principles, methods, and/or significant changes in tax law that are not reflected in externally reported diluted earnings per share. See Appendix A for a reconciliation of adjusted EPS as used for external reporting to its most directly comparable GAAP financial measure. | ||
