EARNINGS PER SHARE

NOTE 19. EARNINGS PER COMMON SHARE ATTRIBUTABLE TO CUMMINS INC.

We calculate basic earnings per share (EPS) of common stock by dividing net income attributable to Cummins Inc. by the weighted-average number of common shares outstanding for the period. The calculation of diluted EPS assumes the issuance of common stock for all potentially dilutive share equivalents outstanding. We excluded shares of common stock held in the Employee Benefits Trust (EBT) from the calculation of the weighted-average common shares outstanding until those shares are distributed from the EBT to the Retirement Savings Plan. The EBT was fully depleted at December 31, 2021. Following are the computations for basic and diluted earnings per share:
