Pay vs Performance Disclosure          
Pay vs Performance Disclosure, Table
Pay Versus Performance
Commission rules adopted in 2022 pursuant to the Dodd-Frank Act require most companies with publicly traded stock in the United States to describe the relationship between compensation actually paid (“CAP”) to their named executive officers, as calculated in accordance with the Commission’s rules, and the Company’s performance represented by total stockholder return (“TSR”), net income and a Company-selected financial performance measure.
To determine the executive compensation that is “actually paid” for the principal executive officer (the “PEO”) and
non-PEO
named executive officers
(“non-PEO
NEOs”) in a given year, companies are required to make certain adjustments to the total executive compensation reported in the summary compensation table (“SCT”) for pension and equity awards that are calculated in accordance with U.S. GAAP.
For the pension adjustment, the aggregate change in the pension value as reflected in the SCT is deducted and the service cost and prior service cost for the year is included.
For equity awards, the grant date value as reported in the SCT is subtracted and a new value is added, which is calculated as follows: the
year-end
fair value of awards granted in the current fiscal year plus or minus the annual change in fair value as of the
year-end
for any unvested awards or as of vesting for awards vested in the current year.
We disclose below pay versus performance information, including the relationship between CAP, as calculated in accordance with the Commission’s rules, and Company performance.
