Note 17. Earnings per Share

Westrock Series A Preferred Shares and our RSUs issued under our 2022 Equity Plan are considered participating securities as they receive non-forfeitable rights to dividends at the same rate as Common Shares. As participating securities, we include these instruments in the computation of earnings per share under the two-class method described in ASC 260 Earnings per Share (“ASC 260”).

The dilutive effect of Westrock Series A Preferred Shares and the Convertible Notes is calculated using the if-converted method, which assumes an add-back of any accretion on preferred shares and interest expense associated with the Convertible Notes to net income attributable to shareholders as if the securities were converted to Common Shares at the beginning of the reporting period (or at the time of issuance, if later), and the resulting Common Shares being included in the number of weighted-average units outstanding.

The dilutive effect of time-based option awards and RSUs is calculated using the treasury stock method, while performance-based awards are treated as contingently issuable.

The following potentially dilutive securities were excluded from the computation of diluted shares for the periods indicated because their inclusion would have an anti-dilutive effect on dilutive earnings (loss) per common share.

The following table sets forth the computation of basic and diluted earnings per share under the two-class method for the periods indicated.
