GOODWILL AND OTHER INTANGIBLES [Abstract]
GOODWILL AND OTHER INTANGIBLES	NOTE 6 – GOODWILL AND OTHER INTANGIBLES Goodwill Goodwill as 38.6 The Corporation’s policy is to assess goodwill and other intangibles for impairment on an annual basis during the fourth quarter of each year, and more frequently if events or circumstances lead management to believe that the values of goodwill or other intangibles may be impaired. During the fourth quarter of 2023, management performed a qualitative analysis of the carrying amount of each relevant reporting units’ goodwill and concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. This assessment involved identifying the inputs and assumptions that most affect fair value, including evaluating significant and relevant events impacting each reporting entity, and evaluating such factors to determine if a positive assertion can be made that it is more-likely- than-not that the fair value of the reporting units exceeded their carrying amount. As of December 31, 2023, the Corporation concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. The Corporation determined that there have been no significant events since the last annual assessment that could indicate potential goodwill impairment on reporting units for which the goodwill is allocated. As a result, no impairment charges for goodwill were recorded during the first quarter of 2024. There were no Other Intangible Assets The amortization as of the indicated dates: As of As of March 31, December 31, 2024 2023 (Dollars in thousands) Core deposit intangible: Gross amount $ 87,544 $ 87,544 Accumulated amortization (76,002) (74,161) Net carrying amount $ 11,542 $ 13,383 Remaining amortization period (in years) 5.8 6.0 During 1.8 2.0 amortization expense on its other intangibles subject to amortization.

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 .

The fair value of the performance units awarded during the quarters ended March 31, 2024 and 2023, that was based on the TBVPS goal component, was calculated based on the market price of the Corporation’s common stock on the respective date of the grant and assuming attainment of 100% of target opportunity. As of March 31, 2024, there have been no changes in management’s assessment of the probability that the pre-established TBVPS goal will be achieved; as such, no cumulative adjustment to compensation expense has been recognized. The fair value of the performance units awarded, that was based on the Relative TSR component, was calculated using a Monte Carlo simulation. Since the Relative TSR component is considered a market condition, the fair value of the portion of the award based on Relative TSR is not revised subsequent to grant date based on actual performance.

Goodwill Impaired Facts And Circumstances Leading To Impairment			The Corporation’s policy is to assess goodwill and other intangibles for impairment on an annual basis during the fourth quarter of each year, and more frequently if events or circumstances lead management to believe that the values of goodwill or other intangibles may be impaired. During the fourth quarter of 2023, management performed a qualitative analysis of the carrying amount of each relevant reporting units’ goodwill and concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. This assessment involved identifying the inputs and assumptions that most affect fair value, including evaluating significant and relevant events impacting each reporting entity, and evaluating such factors to determine if a positive assertion can be made that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying amount. As of December 31, 2023, the Corporation concluded that it is more-likely-than-not that the fair value of the reporting units exceeded their carrying value. The Corporation determined that there have been no significant events since the last annual assessment that could indicate potential goodwill impairment on reporting units for which the goodwill is allocated. As a result, no impairment charges for goodwill were recorded during the first quarter of 2024.

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

Granted performance units	165,487	216,876
Performance units program description	Performance units granted during the quarters ended March 31, 2024 and 2023 vest on the third anniversary of the effective date of the award based on actual achievement of two performance metrics weighted equally: relative total shareholder return (“Relative TSR”), compared to companies that comprise the KBW Nasdaq Regional Banking Index, and the achievement of a tangible book value per share (“TBVPS”) goal, which is measured based upon the growth in the tangible book value during the performance cycle, adjusted for certain allowable non-recurring transactions. The participant may earn 50% of their target opportunity for threshold level performance and up to 150% of their target opportunity for maximum level performance, based on the individual achievement of each performance goal during a three-year performance cycle. Amounts between threshold, target and maximum performance will vest in a proportional amount.
Stock-based compensation expense	$ 0.5	$ 0.5
Unrecognized compensation cost related to unvested performance units	$ 5.6
Period for cost recognition not yet recognized	2 years 4 months 24 days
Fair Value assumptions method used	The fair value of the performance units awarded during the quarters ended March 31, 2024 and 2023, that was based on the TBVPS goal component, was calculated based on the market price of the Corporation’s common stock on the respective date of the grant and assuming attainment of 100% of target opportunity. As of March 31, 2024, there have been no changes in management’s assessment of the probability that the pre-established TBVPS goal will be achieved; as such, no cumulative adjustment to compensation expense has been recognized. The fair value of the performance units awarded, that was based on the Relative TSR component, was calculated using a Monte Carlo simulation. Since the Relative TSR component is considered a market condition, the fair value of the portion of the award based on Relative TSR is not revised subsequent to grant date based on actual performance.

Puerto Rico Banking Law Description				The Puerto Rico Banking Law provides that, when the expenditures of a Puerto Rico commercial bank are greater than receipts, the excess of the expenditures over receipts must be charged against the undistributed profits of the bank, and the balance, if any, must be charged against the legal surplus reserve, as a reduction thereof. 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.
