The Company calculates basic earnings per common share by dividing net income attributable to the Company's common stockholders for the period by weighted-average shares of common stock outstanding for that period. Diluted earnings per common share takes into account the effect of dilutive instruments, such as performance share units ("PSUs"), restricted stock units ("RSUs") and deferred stock units ("DSUs"), and the number of incremental shares that are to be added to the weighted-average number of shares outstanding.

During the three months ended March 31, 2026 and 2025, certain of the PSUs, RSUs and DSUs awarded under the 2017 Plan were determined to be dilutive and were included in the calculation of diluted earnings per common share under the treasury stock method. Under this method, common equivalent shares are calculated assuming that target PSUs and outstanding RSUs and DSUs vest according to the respective PSU, RSU and DSU agreements and unrecognized compensation cost is used to repurchase shares of the Company’s outstanding common stock at the average market price during the reported period.

The following table presents the computation of basic and diluted earnings per common share for the periods indicated (dollar and share amounts in thousands, except per share amounts):
