As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship between the change in assumption and the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSR is calculated without changing any other assumption; in reality, changes in one factor may result in changes in another (for example, increases in market interest rates may result in lower prepayments), which may magnify or counteract the sensitivities .

Servicing Assets and Servicing Liabilities at Fair Value, Assumptions Used to Estimate Fair Value, Qualitative Information					These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship between the change in assumption and the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the MSR is calculated without changing any other assumption; in reality, changes in one factor may result in changes in another (for example, increases in market interest rates may result in lower prepayments), which may magnify or counteract the sensitivities

Performance units program description	These awards do not contain non-forfeitable rights to dividend equivalent amounts and can only be settled in shares of the Corporation’s common stock. 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 as of December 31, 2023. 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.

If the legal surplus reserve is not sufficient to cover such balance in whole or in part, the outstanding amount must be charged against the capital account and the Bank cannot pay dividends until it can replenish the legal surplus reserve to an amount of at least 20% of the original capital contributed.
