Diluted average common shares used in the diluted loss per common share calculation for fiscal 2022 were 55.5 million, which excluded potential Common Shares of 0.6 million because the effect of their inclusion would be anti-dilutive as the Company incurred a net loss for fiscal 2022. Diluted average common shares used in the diluted income per common share calculation were 57.2 million and 56.9 million for fiscal 2021 and fiscal 2020, respectively, which included dilutive potential Common Shares of 1.5 million and 1.2 million, respectively.

Stock options with exercise prices greater than the average market price of the underlying Common Shares are excluded from the computation of diluted income per common share because they are out-of-the-money and the effect of their inclusion would be anti-dilutive. For fiscal 2022 and fiscal 2021, the average number of out-of-the money options was 0.2 million and 0.1 million, respectively. There were no out-of-the-money options for fiscal 2020.
