(1)Options/SARs to purchase 888,726, 672,485 and 343,715 shares of the Company’s common stock were excluded from the computations of diluted earnings per share for the years ended December 31, 2024, 2023 and 2022, respectively. The options’/SARs’ exercise prices were greater than the average market price for the Company’s common stock and inclusion of the instruments would have had an antidilutive effect on the computations of earnings per share.
