[1] Despite being included currently in Diluted net earnings per common share, the actual conversion to common stock occurs when the preferred shares are sold. Shares may only be sold after being allocated to the ESOP participants pursuant to the repayment of the ESOP's obligations through 2035.

[2] Weighted average outstanding stock options of approximately 12 million and 7 million for the three months ended March 31, 2021 and 2020, and approximately 8 million and 3 million for the nine months ended March 31, 2021 and 2020, respectively, were not included in the Diluted net earnings per share calculation because the options were out of the money or to do so would have been antidilutive (i.e., the total proceeds upon exercise would have exceeded the market value of the underlying common shares).

[3] Basic net earnings per share and Diluted net earnings per share are calculated on Net earnings attributable to Procter & Gamble.
