(1) Interest expense for the years ended December 31, 2021, 2020 and 2019 has been tax effected at a rate of 21%. For the years ended December 31, 2021, 2020, and 2019, all of our then outstanding 9% Debentures are reflected in diluted earnings per share using the “if-converted” method. Under this method, if dilutive, the common stock related to the outstanding 9% Debentures is assumed issued as of the beginning of the reporting period and the related interest expense, net of tax, is added back to earnings in calculating diluted EPS.
