Basic EPS is calculated by dividing Net earnings by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case includes shares issuable under share-based compensation plans.

The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted EPS calculations for the three and nine months ended September 30:


	Three months ended		Nine months ended
In millions	2026	2025	2026	2025
Weighted-average number of basic shares	84.8	85.9	85.5	86.1
Shares issuable under share-based compensation plans	0.4	0.6	0.4	0.5
Weighted-average number of diluted shares	85.2	86.5	85.9	86.6

At September 30, 2026 and 2025, 0.2 million shares issuable under share-based compensation plans were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.
