The allocation of earnings and dividends to participating securities in the preceding table represents dividends paid during the year to participating securities, consisting of certain RSUs, as well as the RSAs granted as part of our acquisition of TriState Capital, plus an allocation of undistributed earnings to such participating securities. Participating securities and related dividends paid on these participating securities were insignificant for the years ended September 30, 2022, 2021 and 2020. Undistributed earnings are allocated to participating securities based upon their right to share in earnings if all earnings for the period had been distributed.
