Non-GAAP Measure Description

(7)The Company-selected measure, which is a measure the Company believes represents the most important financial performance not otherwise presented in the table above that the Company uses to link CAP to the NEOs for fiscal year 2023 to the Company's performance is Return on Invested Capital ("ROIC"), a non-GAAP measure. ROIC is defined as adjusted net income before interest (defined as income from continuing operations, as reported in the Company's audited financial statements plus after tax restructuring charges, senior leadership transition costs, acquisition related items, portfolio management, other special costs or intangible asset impairment charges, if any in applicable year, and tax effected interest expense), divided by average adjusted invested capital (the 13-month average of total stockholders' equity adjusted for special charges plus debt, minus cash for the applicable year). While the Company uses numerous financial measures for purposes of evaluating performance for the Company's compensation programs, the Company has determined that ROIC is the financial performance measure that, in the Company's assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the company to link compensation actually paid to the company's NEOs, for the most recently completed fiscal year, to Company performance.
