Net Income Per Share [Abstract]
Net Income Per Share	Note 3: Net Income per Share Net income per share is computed by dividing net income by the weighted-average number of shares of the Company’s Class A Common Stock, par value $0.001 per share (“Class A Common Stock”), and the Company’s Class B Common Stock, par value $0.001 per share (“Class B Common Stock” and, together with Class A Common Stock, “Common Stock”), outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of Common Stock outstanding, including potentially dilutive shares of Common Stock equivalents outstanding during the period. The dilutive effect of potential shares of Common Stock are determined using the treasury stock method. The following table sets forth the computation of basic and diluted net income per common share under the treasury stock method for the thirteen-week periods ended November 27, 2021 and November 28, 2020. Thirteen Weeks Ended November 27, November 28, 2021 2020 Numerator: Net income attributable to MSC Industrial as reported $ 66,067 $ 38,454  Denominator: Weighted-average shares outstanding for basic net income per share 55,530 55,659  Effect of dilutive securities 326 191  Weighted-average shares outstanding for diluted net income per share 55,856 55,850  Net income per share: Basic $ 1.19 $ 0.69  Diluted $ 1.18 $ 0.69  Potentially dilutive securities 434 1,332  Potentially dilutive securities attributable to outstanding stock options and restricted stock units are excluded from the calculation of diluted net income per share when the combined exercise price and average unamortized fair value are greater than the average market price of Class A Common Stock, and, therefore, their inclusion would be anti-dilutive.
