Performance units program description     The performance units will vest on the third anniversary of the effective date of the awards, subject to the achievement of a pre-established tangible book value per share target. All the performance units will vest if performance is at the pre-established performance target level or above. However, the participants may vest with respect to 50% of the awards to the extent that performance is below the target but not less than 80% of the pre-established performance target level (the “80% minimum threshold”), which is measured based upon the growth in the tangible book value during the performance cycle. If performance is between the 80% minimum threshold and the pre-established performance target level, the participants will vest on a proportional amount. No performance units will vest if performance is below the 80% minimum threshold. The performance units granted in the first half of 2022 are for the performance period beginning January 1, 2022 and ending on December 31, 2024.
