The difference in the weighted average 3M shares outstanding for calculating basic and diluted earnings per share attributable to 3M common shareholders is the result of the dilution associated with the Company’s stock-based compensation plans. Certain awards outstanding under these stock-based compensation plans were not included in the computation of diluted earnings per share attributable to 3M common shareholders because they would have had an anti-dilutive effect of 31.1 million and 32.3 million average options for the three and nine months ended September 30, 2024, respectively, and 35.6 million and 36.0 million average options for the three and nine months ended September 30, 2023, respectively. In periods of net losses, these anti-dilutive effects include all weighted option shares outstanding and weighted average shares is the same for the calculations of both basic and diluted loss per share. The computations for basic and diluted earnings (loss) per share follow:
