Basis of Presentation and Significant Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES [Text Block]	NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The Consolidated Financial Statements (unaudited) of First BanCorp. (the “Corporation”) have been prepared in conformity with the accounting policies stated in the Corporation’s Audited Consolidated Financial Statements for the fiscal year ended December 31, 2021 (the “audited consolidated financial statements”) included in the 2021 Annual Report on Form 10-K. Certain information and note disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted from these statements pursuant to the rules and regulations of the SEC and, accordingly, these financial statements should be read in conjunction with the audited consolidated financial statements, which are included in the 2021 Annual Report on Form 10-K. All adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the statement of financial position, results of operations and cash flows for the interim periods have been reflected. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the quarter ended March 31, 2022 are not necessarily indicative of the results to be expected for the entire year. Adoption of New Accounting Requirements The Corporation was not impacted by the adoption of the following Accounting Standards Updates (“ASUs”) during the first quarter of 2022:  ASU 2021-05, “Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments”  ASU 2021-04, “Earnings Per Share (Topic 260), Debt – Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a Consensus of the Emerging Issues Task Force)”  ASU 2020-06, “Debt – Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in an Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” Recently Issued Accounting Standards Not Yet Effective or Not Yet Adopted Standard Description Effective Date Effect on the financial statements ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” In March 2022, the FASB issued ASU 2022-02 which eliminates the troubled debt restructurings (“TDRs”) recognition and measurement guidance, enhances disclosure requirements for loan restructurings by creditors made to borrowers experiencing financial difficulty for which the terms of the receivables have been modified, and amends the guidance on vintage disclosures to require disclosure of gross write-offs by year of origination. January 1, 2023, unless early adopted in which case the amendments should be applied as of the beginning of the fiscal year that includes the interim period The Corporation is evaluating the impact that this ASU will have on its financial statements and disclosures. The Corporation expects to adopt the amendments of this update during the first quarter of 2023 using a modified retrospective transition method to adjust the ACL for loans modified as a TDR prior to the adoption of these amendments. ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method” In March 2022, the FASB issued ASU 2022-01 which, among others, expands the current last-of-layer method to allow multiple hedged layers and the scope of the portfolio layer method to non-prepayable financial assets. January 1, 2023, unless early adopted in which case the amendments should be applied as of the beginning of the fiscal year that includes the interim period The Corporation does not expect to be impacted by the amendments of this update since it does not apply fair value hedge accounting to any of its derivatives. For other recently issued Accounting Standards not yet effective or not yet adopted, see Note 1 – Nature of Business and Summary of Significant Accounting Policies included in the 2021 Annual Report on Form 10-K.

During 2021, the Corporation placed this instrument in nonaccrual status based on the delinquency status of the underlying second mortgage loans collateral. Maturities of MBS are based on the period of final contractual maturity. Expected maturities of investments might differ from contractual maturities because they may be subject to prepayments and/or call options. The weighted-average yield on investment securities available for sale is based on amortized cost and, therefore, does not give effect to changes in fair value. The net unrealized gain or loss on securities available for sale is presented as part of accumulated other comprehensive income (loss). The following tables show the fair value and gross unrealized losses of the Corporation’s available-for-sale investment securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of March 31, 2022 and December 31, 2021. The tables also include debt securities for which an ACL was recorded.

As of December 31, 2021, PRHFA bond and private label MBS had an ACL of $ 0.3 million and $ 0.8 million, respectively. Assessment for Credit Losses Debt securities issued by U.S. government agencies, U.S. government-sponsored entities (“GSEs”), and the U.S. Treasury, including notes and MBS, accounted for approximately 99% of the total available-for-sale portfolio as of March 31, 2022 and the Corporation expects no credit losses on these securities, given the explicit and implicit guarantees provided by the U.S. federal government. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and because the Corporation does not have the intent to sell these U.S. government and agencies debt securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Corporation does not consider impairments on these securities to be credit related as of March 31, 2022. The Corporation’s credit loss assessment was concentrated mainly on private label MBS, and on Puerto Rico government debt securities, for which credit losses are evaluated on a quarterly basis. The Corporation’s available-for-sale MBS portfolio included private label MBS with a fair value of $ 6.9 million, which had unrealized losses of approximately $ 2.6 million as of March 31, 2022, of which $ 0.4 million is due to credit deterioration and is part of the ACL. The interest rate on these private-label MBS is variable, tied to 3-month LIBOR, and limited to the weighted-average coupon on the underlying collateral. The underlying collateral are fixed-rate, single-family residential mortgage loans in the United States with original FICO scores over 700 and moderate loan-to-value ratios (under 80%), as well as moderate delinquency levels. As of March 31, 2022, the Corporation did not have the intent to sell these securities and determined that it is likely that it will not be required to sell the securities before anticipated recovery. The Corporation determined the ACL for private label MBS based on a risk-adjusted discounted cash flow methodology that considers the structure and terms of the instruments. The Corporation utilized probability of default (“PDs”) and loss given default (“LGDs”) that considered, among other things, historical payment performance, loan-to value attributes and relevant current and forward-looking macroeconomic variables, such as regional unemployment rates and the housing price index. Under this approach, all future cash flows (interest and principal) from the underlying collateral loans, adjusted by prepayments and the PDs and LGDs, were discounted at the effective interest rate as of the reporting date. Significant assumptions in the valuation of the private label MBS were as follows: As of As of March 31, 2022 December 31, 2021 Weighted Range Weighted Range Average Minimum Maximum Average Minimum Maximum Discount rate 14.3% 14.3% 14.3% 12.9% 12.9% 12.9% Prepayment rate 14.4% 9.4% 24.1% 15.2% 7.6% 24.9% Projected Cumulative Loss Rate 6.5% 0.3% 14.9% 7.6% 0.2% 15.7% The Corporation evaluates if a credit loss exists, primarily by monitoring adverse variances in the present value of expected cash flows. As of March 31, 2022, the ACL for these private label MBS was $ 0.4 million, compared to $ 0.8 million as of December 31, 2021. As of March 31, 2022, the Corporation’s available-for-sale investment securities portfolio also included a residential pass-through MBS issued by the PRHFA, collateralized by certain second mortgages, with a fair value of $ 2.7 million, which had an unrealized loss of approximately $ 0.8 million. Approximately $ 0.3 million of the unrealized losses was due to credit deterioration and is part of the ACL. The underlying second mortgage loans were originated under a program launched by the Puerto Rico government in 2010. This residential pass-through MBS was structured as a zero-coupon bond for the first ten years (up to July 2019). The underlying source of repayment on this residential pass-through MBS is second mortgage loans in Puerto Rico. PRHFA, not the Puerto Rico government, provides a guarantee in the event of default and subsequent foreclosure of the properties underlying the second mortgage loans. During 2021, the Corporation placed this instrument in nonaccrual status based on the delinquency status of the underlying second mortgage loans collateral. The Corporation determined the ACL on this instrument based on a risk-adjusted discounted cash flow methodology that considered the structure and terms of the underlying collateral. The Corporation utilized PDs and LGDs that considered, among other things, historical payment performance, loan-to value attributes and relevant current and forward-looking macroeconomic variables, such as regional unemployment rates, the housing price index and expected recovery from the PRHFA guarantee. Under this approach, all future cash flows (interest and principal) from the underlying collateral loans, adjusted by prepayments and the PDs and LGDs, were discounted at the internal rate of return as of the reporting date and compared to the amortized cost. In the event that the second mortgage loans default and the collateral is insufficient to satisfy the outstanding balance of this residential pass-through MBS, PRHFA’s ability to honor its insurance will depend on, among other factors, the financial condition of PRHFA at the time such obligation becomes due and payable. Further deterioration of the Puerto Rico economy or fiscal health of the PRHFA could impact the value of these securities, resulting in additional losses to the Corporation. As of March 31, 2022, the Corporation did not have the intent to sell this security and determined that it was likely that it will not be required to sell the security before its anticipated recovery. Accrued interest receivable on available-for-sale debt securities totaled $ 11.1 million as of March 31, 2022 ($ 10.1 million as of December 31, 2021) and is excluded from the estimate of credit losses.

The Corporation performs periodic credit quality reviews on these issuers. All of the Puerto Rico municipal bonds were current as to scheduled contractual payments as of March 31, 2022. The Puerto Rico municipal bonds had an ACL of $ 12.3 million as of March 31, 2022, a $ 3.7 million increase when compared to $ 8.6 million as of December 31, 2021, primarily reflecting the Corporation’s change of applying probability weights to the baseline and alternative downside economic scenarios to estimate the ACL and the associated impact on qualitative reserves. According to the Corporation’s policy, accrued interest receivable on held-to-maturity debt securities that totaled $ 1.7 million as of March 31, 2022 ($ 3.4 million as of December 31, 2021), was excluded from the estimate of credit losses. The following table presents the activity in the ACL for debt securities held-to-maturity by major security type for the quarters ended March 31, 2022 and 2021: Puerto Rico Municipal Bonds Quarter Ended Quarter Ended March 31, 2022 March 31, 2021 (In thousands) Beginning balance $ 8,571 $ 8,845 Provision for credit losses - expense 3,753 24 $ 12,324 $ 8,869 During the second quarter of 2019, the oversight board established by the Puerto Rico Oversight, Management, and Economic Stability Act (“PROMESA”) announced the designation of Puerto Rico’s 78 municipalities as covered instrumentalities under PROMESA. Municipalities may be affected by the negative economic and other effects resulting from expense, revenue, or cash management measures taken by the Puerto Rico government to address its fiscal situation, or measures included in fiscal plans of other government entities, and, more recently, by the effect of the COVID-19 pandemic on the Puerto Rico and global economy. Given the inherent uncertainties about the fiscal situation of the Puerto Rico central government, the COVID-19 pandemic, and the measures taken, or to be taken, by other government entities in response to the COVID-19 pandemic on municipalities, the Corporation cannot be certain whether future charges to the ACL on these securities will be required. From time to time, the Corporation has securities held to maturity with an original maturity of three months or less that are considered cash and cash equivalents and are classified as money market investments in the consolidated statements of financial condition. As of March 31, 2022 and December 31, 2021, the Corporation had no outstanding securities held to maturity that were classified as cash and cash equivalents. Credit Quality Indicators: The held-to-maturity investment securities portfolio consisted of financing arrangements with Puerto Rico municipalities issued in bond form, which are accounted for as securities, but are underwritten as loans with features that are typically found in commercial loans. Accordingly, the Corporation monitors the credit quality of Puerto Rico municipal bonds held to maturity through the use of internal credit-risk ratings, which are generally updated on a quarterly basis. The Corporation considers a debt security held to maturity as a criticized asset if its risk rating is Special Mention, Substandard, Doubtful or Loss. Puerto Rico municipal bonds that do not meet the criteria for classification as criticized assets are considered to be pass-rated securities. For the definitions of the internal credit-risk ratings, refer to Note 5 – Investment Securities included in the 2021 Annual Report on Form 10-K. The Corporation periodically reviews its assets to evaluate if they are properly classified, and to determine impairment, if any. The frequency of these reviews will depend on the amount of the aggregate outstanding debt, and the risk rating classification of the obligor. The Corporation has a Loan Review Group that reports directly to the Corporation’s Risk Management Committee and administratively to the Chief Risk Officer. The Loan Review Group performs annual comprehensive credit process reviews of the Bank’s commercial loan portfolios, including the above-mentioned Puerto Rico municipal bonds accounted for as held-to-maturity securities. The objective of these loan reviews is to assess accuracy of the Bank’s determination and maintenance of loan risk rating and its adherence to lending policies, practices and procedures. The monitoring performed by this group contributes to the assessment of compliance with credit policies and underwriting standards, the determination of the current level of credit risk, the evaluation of the effectiveness of the credit management process and the identification of any deficiency that may arise in the credit-granting process. Based on its findings, the Loan Review Group recommends corrective actions, if necessary, that help in maintaining a sound credit process. The Loan Review Group reports the results of the credit process reviews to the Risk Management Committee. As of March 31, 2022 and December 31, 2021, all held-to-maturity debt securities were on nonaccrual status, 90 days past due and still accruing, or past due as of March 31, 2022 and December 31, 2021. A security is considered to be past due once it is 30 days contractually past due under the terms of the agreement.

Foreclosure procedures and timelines vary depending on whether the property is located in a judicial or non-judicial state. Judicial states ( i.e ., Puerto Rico, Florida and the USVI) require the foreclosure to be processed through the state’s court while foreclosure in non-judicial states ( i.e., the BVI) is processed without court intervention. Foreclosure timelines vary according to local jurisdiction law and investor guidelines. Occasionally, foreclosures may be delayed due to, among other reasons, mandatory mediations, bankruptcy, court delays, and title issues.

(4) According to the Corporation's delinquency policy and consistent with the instructions for the preparation of the Consolidated Financial Statements for Bank Holding Companies (FR Y-9C) required by the Federal Reserve Board, residential mortgage, commercial mortgage, and construction loans are considered past due when the borrower is in arrears on two or more monthly payments. FHA/VA government-guaranteed loans, conventional residential mortgage loans, and commercial mortgage loans past due 30-59 days, but less than two payments in arrears, as of December 31, 2021 amounted to $ 6.1 million, $ 66.0 million, and $ 0.7 million, respectively. Credit Quality Indicators: The Corporation categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Corporation analyzes non-homogeneous loans, such as commercial mortgage, commercial and industrial, and construction loans individually to classify the loans’ credit risk. As mentioned above, the Corporation periodically reviews its commercial and construction loans to evaluate if they are properly classified. The frequency of these reviews will depend on the amount of the aggregate outstanding debt, and the risk rating classification of the obligor. In addition, during the renewal and annual review process of applicable credit facilities, the Corporation evaluates the corresponding loan grades. The Corporation uses the same definition for risk ratings as those described for Puerto Rico municipal bonds accounted for as held-to-maturity securities, as discussed in Note 5 – Investment Securities, in the 2021 Annual Report on Form 10-K. For residential mortgage and consumer loans, the Corporation also evaluates credit quality based on its interest accrual status. Based on the most recent analysis performed, the amortized cost of commercial and construction loans by portfolio classes and by origination year based on the internal credit-risk category as of March 31, 2022 and the amortized cost of commercial and construction loans by portfolio classes based on the internal credit-risk category as of December 31, 2021 was as follows: As of March 31, 2022 Puerto Rico and Virgin Islands region Term Loans As of December 31, 2021 Amortized Cost Basis by Origination Year (1) (In thousands) 2022 2021 2020 2019 2018 Prior Revolving Loans Amortized Cost Basis Total Total CONSTRUCTION Risk Ratings: Pass $ - $ 3,222 $ 10,366 $ 22,187 $ - $ 4,988 $ - $ 40,763 $ 38,066 Criticized: Special Mention - - - 763 - - - 763 765 Substandard - - - - 560 3,334 - 3,894 4,302 Doubtful - - - - - - - - - Loss - - - - - - - - - Total construction loans $ - $ 3,222 $ 10,366 $ 22,950 $ 560 $ 8,322 $ - $ 45,420 $ 43,133

As of March 31, 2022, the Corporation applied probability weights to the baseline and alternative downside economic scenarios to estimate the ACL with the baseline scenario carrying the highest weight. In weighting these macroeconomic scenarios, the Corporation applied judgment based on a variety of factors such as economic uncertainties including a prolonged conflict in Ukraine, adverse conditions created by disruptions in the supply chain and the overall inflationary environment. For prior periods, the Corporation calculated the ACL using the baseline scenario. As of March 31, 2022, the ACL for loans and finance leases was $ 245.4 million, down $ 23.6 million from December 31, 2021. The ACL reduction for commercial and construction loans was $ 22.3 million in the first quarter of 2022, primarily reflecting reductions in qualitative reserves mostly associated with a continued positive long-term outlook of macroeconomic variables, mainly in the commercial real estate price index, as a result of a reduced uncertainty regarding COVID-19, particularly on loans in the hotel, transportation and entertainment industries and, to a lesser extent, improvements in updated financial information received from borrowers during the first quarter of 2022. In addition, there was an ACL reduction of $ 6.0 million for residential mortgage loans, partially offset by a $ 4.7 million increase in the ACL for consumer loans. The net reduction for residential mortgage loans was primarily driven by the overall decrease in the size of this portfolio and continued improvements in the long-term outlook of forecasted macroeconomic variables, such as the housing price index. The ACL increase for consumer loans consisted of charges to the provision of $ 11.0 million recorded in the first quarter to account for the increase in the size of the portfolio of auto loans and finance leases and an increase in cumulative historical charge-off levels mostly related to the personal and credit card loan portfolio, partially offset by net charge-offs of $ 6.2 million. For those loans where the ACL was determined based on a discounted cash flow model, the change in the ACL due to the passage of time is recorded as part of the provision for credit losses. Total net charge-offs decreased by $ 5.9 million to $ 6.6 million, when compared to the first quarter of 2021. The variance consisted of a $ 3.0 million decrease in net charge-offs of consumer and finance leases, primarily reflected in the auto and personal loan portfolios, and a $ 2.0 million decrease in commercial and construction loans net charge-offs. The tables below present the ACL related to loans and finance leases and the carrying value of loans by portfolio segment as of March 31, 2022 and December 31, 2021: As of March 31, 2022 Residential Mortgage Loans Commercial Mortgage Loans Commercial and Industrial Loans (1) Consumer Loans Construction Loans (Dollars in thousands) Total Total loans held for investment: Amortized cost of loans $ 2,891,699 $ 111,908 $ 2,237,702 $ 2,880,256 $ 2,976,140 $ 11,097,705 Allowance for credit losses 68,820 1,842 30,138 36,784 107,863 245,447 Allowance for credit losses to amortized cost 2.38 % 1.65 % 1.35 % 1.28 % 3.62 % 2.21 % As of December 31, 2021 Residential Mortgage Loans Commercial Mortgage Loans Commercial and Industrial Loans (1) Consumer Loans Construction Loans (Dollars in thousands) Total Total loans held for investment: Amortized cost of loans $ 2,978,895 $ 138,999 $ 2,167,469 $ 2,887,251 $ 2,888,044 $ 11,060,658 Allowance for credit losses 74,837 4,048 52,771 34,284 103,090 269,030 Allowance for credit losses to amortized cost 2.51 % 2.91 % 2.43 % 1.19 % 3.57 % 2.43 % (1) As of March 31, 2022 and December 31, 2021, includes $ 89.7 million and $ 145.0 million of SBA PPP loans, respectively, which require no ACL as these loans are 100% guaranteed by the SBA. In addition, the Corporation estimates expected credit losses over the contractual period in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, such as unfunded loan commitments and standby letters of credit for commercial and construction loans, unless the obligation is unconditionally cancellable by the Corporation. The Corporation estimates the ACL for these off-balance sheet exposures following the methodology described in Note 1 – Nature of Business and Summary of Significant Accounting Policies, in the audited consolidated financial statements, which are included in the 2021 Annual Report on Form 10-K. As of March 31, 2022, the ACL for off-balance sheet credit exposures was $ 1.4 million, compared with $ 1.5 million as of December 31, 2021. The following table presents the activity in the ACL for unfunded loan commitments and standby letters of credit for the quarters ended March 31, 2022 and 2021: Quarter ended March 31, 2022 March 31, 2021 (In thousands) Beginning balance $ 1,537 $ 5,105 Provision for credit losses - (benefit) ( 178) ( 706) Ending balance $ 1,359 $ 4,399

Goodwill and other Intangible Assets [Abstract]
GOODWILL AND OTHER INTANGIBLES [Text Block]	NOTE 7 – GOODWILL AND OTHER INTANGIBLES Goodwill as of each of March 31, 2022 and December 31, 2021 amounted to $ 38.6 million. 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 2021, as part of its annual evaluation, the Corporation performed a qualitative assessment to determine if a goodwill impairment test was necessary. This assessment involved identifying the inputs and assumptions that most affects fair value, evaluating the significance of all identified relevant events and circumstances that affect fair value of the 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 unit is greater than its carrying amount. As of December 31, 2021, 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 impartment charges for goodwill were recorded during the first quarter of 2022. There were no changes in the carrying amount of goodwill during the quarter ended March 31, 2022. The changes in the carrying amount of goodwill attributable to operating segments during 2020 and the quarter ended March 31, 2021 are reflected in the following table Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Banking United States Operations Total (In thousands) Goodwill, January 1, 2020 $ - $ 1,406 $ - $ 26,692 $ 28,098 Merger and acquisitions (1) 574 794 4,935 - 6,303 Measurement period adjustment (1) 385 533 3,313 - 4,231 Goodwill, December 31, 2020 $ 959 $ 2,733 $ 8,248 $ 26,692 $ 38,632 Measurement period adjustment (2) 53 74 ( 148) - ( 21) Goodwill, March 31, 2021 $ 1,012 $ 2,807 $ 8,100 $ 26,692 $ 38,611 (1) Recognized in connection with the BSPR acquisition on September 1, 2020.

The following table shows the gross amount and accumulated amortization of the Corporation’s other intangible assets subject to amortization as of the indicated dates: As of As of March 31, December 31, 2022 2021 (Dollars in thousands) Core deposit intangible: Gross amount $ 87,544 $ 87,544 Accumulated amortization ( 60,896) ( 58,973) Net carrying amount $ 26,648 $ 28,571 Remaining amortization period (in years) 7.8 8.0 Purchased credit card relationship intangible: Gross amount $ 3,800 $ 3,800 Accumulated amortization ( 2,927) ( 2,602) Net carrying amount $ 873 $ 1,198 Remaining amortization period (in years) 1.4 1.7 Insurance customer relationship intangible: Gross amount $ 1,067 $ 1,067 Accumulated amortization ( 940) ( 902) Net carrying amount $ 127 $ 165 Remaining amortization period (in years) 0.8 1.1 During the quarters ended March 31, 2022 and 2021, the Corporation recognized $ 2.3 million and $ 3.0 million, respectively, in amortization expense on its other intangibles subject to amortization. The Corporation amortizes core deposit intangibles and customer relationship intangibles based on the projected useful lives of the related deposits in the case of core deposit intangibles, and over the projected useful lives of the related client relationships in the case of customer relationship intangibles. As mentioned above, the Corporation analyzes core deposit intangibles and customer relationship intangibles annually for impairment, or sooner if events and circumstances indicate possible impairment. Factors that may suggest impairment include customer attrition and run-off. Management is unaware of any events and/or circumstances that would indicate a possible impairment to the core deposit intangibles or customer relationship intangibles as of March 31, 2022. The estimated aggregate annual amortization expense related to the intangible assets subject to amortization for future periods was as follows as of March 31, 2022: Amount (In thousands) 2022 $ 6,550 2023 7,775 2024 6,429 2025 3,437 2026 872 2027 and after 2,585

NON-CONSOLIDATED VARIABLE INTER

NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	3 Months Ended
	Mar. 31, 2022
Transfers and Servicing [Abstract]
NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS [Text Block]	NOTE 8 – NON-CONSOLIDATED VARIABLE INTEREST ENTITIES (“VIE”) AND SERVICING ASSETS The Corporation transfers residential mortgage loans in sale or securitization transactions in which it has continuing involvement, including servicing responsibilities and guarantee arrangements. All such transfers have been accounted for as sales as required by applicable accounting guidance. When evaluating the need to consolidate counterparties to which the Corporation has transferred assets, or with which the Corporation has entered into other transactions, the Corporation first determines if the counterparty is an entity for which a variable interest exists. If no scope exception is applicable and a variable interest exists, the Corporation then evaluates whether it is the primary beneficiary of the VIE and whether the entity should be consolidated or not. Below is a summary of transactions with VIEs for which the Corporation has retained some level of continuing involvement: Trust-Preferred Securities In 2004, FBP Statutory Trust I, a financing trust that is wholly owned by the Corporation, sold to institutional investors $ 100 million of its variable-rate trust-preferred securities (“TRuPs”). FBP Statutory Trust I used the proceeds of the issuance, together with the proceeds of the purchase by the Corporation of $ 3.1 million of FBP Statutory Trust I variable-rate common securities, to purchase $ 103.1 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. Also in 2004, FBP Statutory Trust II, a financing trust that is wholly owned by the Corporation, sold to institutional investors $ 125 million of its variable-rate TRuPs. FBP Statutory Trust II used the proceeds of the issuance, together with the proceeds of the purchase by the Corporation of $ 3.9 million of FBP Statutory Trust II variable-rate common securities, to purchase $ 128.9 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. The debentures, net of related issuance costs, are presented in the Corporation’s consolidated statements of financial condition as other borrowings. The variable-rate TRuPs are fully and unconditionally guaranteed by the Corporation. The Junior Subordinated Deferrable Debentures issued by the Corporation in April 2004 and September 2004 mature on June 17, 2034 and September 20, 2034, respectively; however, under certain circumstances, the maturity of Junior Subordinated Deferrable Debentures may be shortened (such shortening would result in a mandatory redemption of the variable-rate TRuPs). As of each March 31, 2022 and December 31, 2021, these TRuPs amounted to $183.8 million. The Collins Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act eliminated certain TRuPs from Tier 1 Capital; however, these instruments may remain in Tier 2 capital until the instruments are redeemed or mature. Under the indentures, the Corporation has the right, from time to time, and without causing an event of default, to defer payments of interest on the Junior Subordinated Deferrable Debentures by extending the interest payment period at any time and from time to time during the term of the subordinated debentures for up to twenty consecutive quarterly periods. As of March 31, 2022, the Corporation was current on all interest payments due on its subordinated debt. Private Label MBS During 2004 and 2005, an unaffiliated party, referred to in this subsection as the seller, established a series of statutory trusts to effect the securitization of mortgage loans and the sale of trust certificates (“private label MBS”). The seller initially provided the servicing for a fee, which is senior to the obligations to pay private label MBS holders. The seller then entered into a sales agreement through which it sold and issued the private label MBS in favor of the FirstBank. Currently, the Bank is the sole owner of the private label MBS; the servicing of the underlying residential mortgages that generate the principal and interest cash flows is performed by another third party, which receives a servicing fee. These private label MBS are variable-rate securities indexed to 3-month LIBOR plus a spread. The principal payments from the underlying loans are remitted to a paying agent (servicer), who then remits interest to the Bank. Interest income is shared to a certain extent with the FDIC, which has an interest only strip (“IO”) tied to the cash flows of the underlying loans and is entitled to receive the excess of the interest income less a servicing fee over the variable rate income that the Bank earns on the securities. This IO is limited to the weighted-average coupon on the mortgage loans. The FDIC became the owner of the IO upon its intervention of the seller, a failed financial institution. No recourse agreement exists, and the Bank, as the sole holder of the securities, absorbs all risks from losses on non-accruing loans and repossessed collateral. As of March 31, 2022, the amortized cost and fair value of these private label MBS amounted to $ 9.5 million and $ 6.9 million, respectively, with a weighted-average yield of 2.96%, which is included as part of the Corporation’s available-for-sale investment securities portfolio. As described in Note 2 – Investment Securities, above, the ACL on these private label MBS amounted to $ 0.4 million as of March 31, 2022. Investment in unconsolidated entity On February 16, 2011, FirstBank sold an asset portfolio consisting of performing and nonaccrual construction, commercial mortgage and commercial and industrial loans with an aggregate book value of $ 269.3 million to CPG/GS, an entity organized under the laws of the Commonwealth of Puerto Rico and majority owned by PRLP Ventures LLC (“PRLP”), a company created by Goldman, Sachs & Co. and Caribbean Property Group. In connection with the sale, the Corporation received $ 88.5 million in cash and a 35% interest in CPG/GS, and made a loan in the amount of $ 136.1 million representing seller financing provided by FirstBank. The loan was refinanced and consolidated with other outstanding loans of CPG/GS in the second quarter of 2018 and was paid in full in October 2019. FirstBank’s equity interest in CPG/GS is accounted for under the equity method. FirstBank recorded a loss on its interest in CPG/GS in 2014 that reduced to zero the carrying amount of the Bank’s investment in CPG/GS. No negative investment needs to be reported as the Bank has no legal obligation or commitment to provide further financial support to this entity; thus, no further losses have been or will be recorded on this investment. CPG/GS used cash proceeds of the aforementioned seller-financed loan to cover operating expenses and debt service payments, including those related to the loan that was paid off in October 2019. FirstBank will not receive any return on its equity interest until PRLP receives an aggregate amount equivalent to its initial investment and a priority return of at least 12%, which has not occurred, resulting in FirstBank’s interest in CPG/GS being subordinate to PRLP’s interest. CPG/GS will then begin to make payments pro rata to PRLP and FirstBank, 35% and 65%, respectively, until FirstBank has achieved a 12% return on its invested capital and the aggregate amount of distributions is equal to FirstBank’s capital contributions to CPG/GS. The Bank has determined that CPG/GS is a VIE in which the Bank is not the primary beneficiary. In determining the primary beneficiary of CPG/GS, the Bank considered applicable guidance that requires the Bank to qualitatively assess the determination of whether it is the primary beneficiary (or consolidator) of CPG/GS based on whether it has both the power to direct the activities of CPG/GS that most significantly affect the entity’s economic performance and the obligation to absorb losses of, or the right to receive benefits from, CPG/GS that could potentially be significant to the VIE. The Bank determined that it does not have the power to direct the activities that most significantly impact the economic performance of CPG/GS as it does not have the right to manage or influence the loan portfolio, foreclosure proceedings, or the construction and sale of the property; therefore, the Bank concluded that it is not the primary beneficiary of CPG/GS. Servicing Assets (MSRs) The Corporation typically transfers first lien residential mortgage loans in conjunction with GNMA securitization transactions in which the loans are exchanged for cash or securities that are readily redeemed for cash proceeds and servicing rights. The securities issued through these transactions are guaranteed by GNMA and, under seller/servicer agreements, the Corporation is required to service the loans in accordance with the issuers’ servicing guidelines and standards. As of March 31, 2022, the Corporation serviced loans securitized through GNMA with a principal balance of $ 2.1 billion. Also, certain conventional conforming loans are sold to FNMA or FHLMC with servicing retained. The Corporation recognizes as separate assets the rights to service loans for others, whether those servicing assets are originated or purchased. MSRs are included as part of other assets in the consolidated statements of financial condition. The changes in MSRs are shown below for the indicated periods: Quarter ended March 31, March 31, 2022 2021 (In thousands) Balance at beginning of period $ 30,986 $ 33,071 Capitalization of servicing assets 1,130 1,350 Amortization ( 1,330) ( 1,637) Temporary impairment recoveries, net 55 7 Other (1) ( 88) ( 81) Balance at end of period $ 30,753 $ 32,710 (1) Amount represents adjustments related to the repurchase of loans serviced for others. Impairment charges are recognized through a valuation allowance for each individual stratum of servicing assets. The valuation allowance is adjusted to reflect the amount, if any, by which the cost basis of the servicing asset for a given stratum of loans being serviced exceeds its fair value. Any fair value in excess of the cost basis of the servicing asset for a given stratum is not recognized. Changes in the impairment allowance were as follows for the indicated periods: Quarter ended March 31, March 31, 2022 2021 (In thousands) Balance at beginning of period $ 78 $ 202 Recoveries ( 55) ( 7) Balance at end of period $ 23 $ 195 The components of net servicing income, included as part of mortgage banking activities in the consolidated statements of income, are shown below for the indicated periods: Quarter ended March 31, March 31, 2022 2021 (In thousands) Servicing fees $ 2,819 $ 2,915 Late charges and prepayment penalties 194 239 Adjustment for loans repurchased ( 88) ( 81) Servicing income, gross 2,925 3,073 Amortization and impairment of servicing assets ( 1,275) ( 1,630) Servicing income, net $ 1,650 $ 1,443 The Corporation’s MSRs are subject to prepayment and interest rate risks. Key economic assumptions used in determining the fair value at the time of sale of the related mortgages for the indicated periods ranged as follows: Weighted Average Maximum Minimum Three-Month Period Ended March 31, 2022: Constant prepayment rate: Government-guaranteed mortgage loans 6.7 % 18.3 % 4.8 % Conventional conforming mortgage loans 6.6 % 18.4 % 3.4 % Conventional non-conforming mortgage loans 6.6 % 21.9 % 4.9 % Discount rate: Government-guaranteed mortgage loans 12.0 % 12.0 % 12.0 % Conventional conforming mortgage loans 10.0 % 10.0 % 10.0 % Conventional non-conforming mortgage loans 12.3 % 14.5 % 12.0 % Three-Month Period Ended March 31, 2021: Constant prepayment rate: Government-guaranteed mortgage loans 6.0 % 14.0 % 4.5 % Conventional conforming mortgage loans 6.1 % 17.4 % 3.6 % Conventional non-conforming mortgage loans - % - % - % Discount rate: Government-guaranteed mortgage loans 12.0 % 12.0 % 12.0 % Conventional conforming mortgage loans 10.0 % 10.0 % 10.0 % Conventional non-conforming mortgage loans - % - % - % The weighted-averages of the key economic assumptions that the Corporation used in its valuation model and the sensitivity of the current fair value to immediate 10% and 20% adverse changes in those assumptions for mortgage loans as of March 31, 2022 and December 31, 2021 were as follows: March 31, December 31, 2022 2021 (In thousands) Carrying amount of servicing assets $ 30,753 $ 30,986 Fair value $ 43,037 $ 42,132 Weighted-average expected life (in years) 7.97 7.96 Constant prepayment rate (weighted-average annual rate) 6.59% 6.55% Decrease in fair value due to 10% adverse change $ 1,051 $ 1,027 Decrease in fair value due to 20% adverse change $ 2,057 $ 2,011 Discount rate (weighted-average annual rate) 11.17% 11.17% Decrease in fair value due to 10% adverse change $ 1,911 $ 1,852 Decrease in fair value due to 20% adverse change $ 3,671 $ 3,561 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.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE [Text Block]	NOTE 13 – EARNINGS PER COMMON SHARE The calculations of earnings per common share for the quarters ended March 31, 2022 and 2021 are as follows: Quarter Ended March 31, March 31, 2022 2021 (In thousands, except per share information) Net income $ 82,600 $ 61,150 Less: Preferred stock dividends - ( 669) Net income attributable to common stockholders $ 82,600 $ 60,481 Weighted-Average Shares: Average common shares outstanding 198,130 217,033 Average potential dilutive common shares 1,407 1,244 Average common shares outstanding-assuming dilution 199,537 218,277 Earnings per common share: Basic $ 0.42 $ 0.28 Diluted $ 0.41 $ 0.28 Earnings per common share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares issued and outstanding. Net income attributable to common stockholders represents net income adjusted for any preferred stock dividends, including any dividends declared but not yet paid, and any cumulative dividends related to the current dividend period that have not been declared as of the end of the period. Basic weighted-average common shares outstanding exclude unvested shares of restricted stock that do not contain non-forfeitable dividend rights. Potential dilutive common shares consist of unvested shares of restricted stock that do not contain non-forfeitable dividend rights using the treasury stock method. This method assumes that proceeds equal to the amount of compensation cost attributable to future services is used to repurchase shares on the open market at the average market price for the period. The difference between the number of potential dilutive shares issued and the shares purchased is added as incremental shares to the actual number of shares outstanding to compute diluted earnings per share. Unvested shares of restricted stock outstanding during the period that result in lower potentially dilutive shares issued than shares purchased under the treasury stock method are not included in the computation of dilutive earnings per share since their inclusion would have an antidilutive effect on earnings per share. Potential dilutive common shares also include performance units that do not contain non-forfeitable dividend rights if the performance condition is met as of the end of the reporting period.

STOCK-BASED COMPENSATION

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION [Text Block]	NOTE 14 – STOCK-BASED COMPENSATION On May 24, 2016, the Corporation’s stockholders approved the amendment and restatement of the First BanCorp. Omnibus Incentive Plan, as amended (the “Omnibus Plan”), to, among other things, increase the number of shares of common stock reserved for issuance under the Omnibus Plan, extend the term of the Omnibus Plan to May 24, 2026, and re-approve the material terms of the performance goals under the Omnibus Plan for purposes of the then-effective Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended. The Omnibus Plan provides for equity-based and non equity-based compensation incentives (the “awards”) through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, other stock-based awards, and cash-based awards. The Omnibus Plan authorizes the issuance of up to 14,169,807 shares of common stock, subject to adjustments for stock splits, reorganizations and other similar events. As of March 31, 2022, there were 3,845,904 authorized shares of common stock available for issuance under the Omnibus Plan. The Corporation’s Board of Directors, based on the recommendation of the Corporation’s Compensation and Benefits Committee, has the power and authority to determine those eligible to receive awards and to establish the terms and conditions of any awards, subject to various limits and vesting restrictions that apply to individual and aggregate awards. Restricted Stock Under the Omnibus Plan, the Corporation may grant restricted stock to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While the restricted stock is subject to forfeiture and does not contain non-forfeitable dividend rights, participants may exercise full voting rights with respect to the shares of restricted stock granted to them. The restricted stock granted under the Omnibus Plan is typically subject to a vesting period. During the first quarter of 2022, the Corporation awarded to an independent director 3,048 shares of restricted stock that are subject to one-year 296,392 shares of restricted stock to employees; fifty percent ( 50%) of those shares vest on the two-year anniversary of the grant date and the remaining 50% vest on the three-year anniversary of the grant date. Included in those 296,392 shares of restricted stock were 6,084 shares granted to retirement-eligible employees. The total expense determined for the restricted stock awarded to retirement-eligible employees was charged against earnings as of the grant date. Common shares issued during the first quarter of 2022 in connection with restricted stock awards were reissued from treasury shares. During the first quarter of 2021, the Corporation awarded to an independent director 3,552 shares of restricted stock that were subject to one-year 288,649 shares of restricted stock to employees; 50% of those shares vest on the two-year anniversary of the grant date and the remaining 50% vest on the three-year anniversary of the grant date. Included in those 288,649 shares of restricted stock were 19,271 shares granted to retirement-eligible employees. The fair value of the shares of restricted stock granted in the first quarter of 2022 and 2021 was based on the market price of the Corporation’s outstanding common stock on the date of the respective grant. The following table summarizes the restricted stock activity in the first quarter of 2022 under the Omnibus Plan: Quarter Ended March 31, 2022 Number of shares of Weighted-Average restricted Grant Date stock Fair Value Unvested shares outstanding at beginning of period 1,148,775 $ 6.61 Granted 299,440 13.15 Forfeited ( 3,092) 6.69 Vested ( 487,198) 5.72 Unvested shares outstanding as of March 31, 2022 957,925 $ 9.10 For each of the quarters ended March 31, 2022 and 2021, the Corporation recognized $ 0.9 million of stock-based compensation expense related to restricted stock awards. As of March 31, 2022, there was $ 6.1 million of total unrecognized compensation cost related to unvested shares of restricted stock. The weighted average period over which the Corporation expects to recognize such cost was 2.0 years as of March 31, 2022. Stock-based compensation accounting guidance requires the Corporation to reverse compensation expense for any awards that are forfeited due to employee or director turnover. Changes in the estimated forfeiture rate may have a significant effect on stock-based compensation, as the Corporation recognizes the effect of adjusting the rate for all expense amortization in the period in which the forfeiture estimate is changed. If the actual forfeiture rate is higher than the estimated forfeiture rate, an adjustment is made to increase the estimated forfeiture rate, which will decrease the expense recognized in the financial statements. If the actual forfeiture rate is lower than the estimated forfeiture rate, an adjustment is made to decrease the estimated forfeiture rate, which will increase the expense recognized in the financial statements. Performance Units Under the Omnibus Plan, the Corporation may award performance units to Omnibus Plan participants. During the first quarter of 2022, the Corporation granted 166,669 units to executives, with each unit representing the value of one share of the Corporation’s common stock. The performance units granted in 2022 are for the performance period beginning January 1, 2022 and ending on December 31, 2024. 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 189,645 shares of common stock related to performance units granted in 2019 that met the pre-established target and vested in the first quarter. During the first quarter of 2021, the Corporation awarded 160,485 performance units to executives. The performance units will vest on the third anniversary 304,408 shares of common stock related to performance units granted in 2018 that met the pre-established target and vested in the first quarter of 2021. The following table summarizes the performance units activity in the first quarter of 2022 under the Omnibus Plan: Quarter Ended (Number of units) March 31, 2022 Performance units at beginning of year 814,899 Additions 166,669 Vested ( 189,645) Performance units as of March 31, 2022 791,923 The fair values of the performance units awarded were based on the market price of the Corporation’s outstanding common stock on the respective date of the grant. For the quarters ended March 31, 2022 and 2021, the Corporation recognized $ 0.3 million and $ 0.5 million, respectively, of stock-based compensation expense related to performance units. As of March 31, 2022, there was $ 4.0 million of total unrecognized compensation cost related to unvested performance units that the Corporation expects to recognize over the next three years. The total amount of compensation expense recognized reflects management’s assessment of the probability that the pre-established performance goal will be achieved. The Corporation will recognize a cumulative adjustment to compensation expense in the then-current period to reflect any changes in the probability of achievement of the performance goals. Shares withheld During the quarter ended March 31, 2022, the Corporation withheld 201,930 shares (first quarter of 2021 – 194,471 shares) of the restricted stock and performance units that vested during such period to cover the officers’ payroll and income tax withholding liabilities; these shares are held as treasury shares. The Corporation paid in cash any fractional share of salary stock to which an officer was entitled. In the consolidated financial statements, the Corporation presents shares withheld for tax purposes as common stock repurchases.

STOCKHOLDERS' EQUITY [Text Block]	NOTE 15 – STOCKHOLDERS’ EQUITY Stock Repurchase Program During the first quarter of 2022 the Corporation completed the $ 300 million stock repurchase program approved by the Board of Directors on April 26, 2021 by purchasing though open market transactions 3,409,697 million shares of common stock for a total purchase price of $ 50 million that remained in the program. On April 27, 2022, the Corporation announced that its Board of Directors approved a new stock repurchase program, under which the Corporation may repurchase up to $ 350 million of its outstanding common stock, to be executed through the next four quarters, commencing in the second quarter of 2022. Repurchases under the program may be executed through open market purchases, accelerated share repurchases and/or privately negotiated transactions or plans, including plans complying with Rule 10b5-1 under the Exchange Act. The Corporation’s common stock repurchase program is subject to various factors, including the Corporation’s capital position, liquidity, financial performance and alternative uses of capital, stock trading price, and general market conditions. The repurchase program may be modified, extended, suspended, or terminated at any time at the Corporation’s discretion. The program does not obligate the Corporation to acquire any specific number of shares. Common Stock The following table shows the change in shares of common stock outstanding in the first quarter of 2022: Quarter Ended March 31, 2022 Common stock outstanding, beginning balance 201,826,505 Common stock repurchased (1) ( 3,611,627) Common stock reissued 489,085 Restricted stock forfeited ( 3,092) Common stock outstanding, ending balance 198,700,871 (1) Includes 201,930 shares of common stock surrender to cover officers' payroll and income taxes and 3,409,697 shares of common stock repurchased in the open market at an average price of $ 14.66 for a total purchase price of approximately $ 50 million. For the quarters ended March 31, 2022 and 2021, total cash dividends declared on shares of common stock amounted to $ 19.9 million and $ 15.3 million, respectively. On April 27, 2022 , the Corporation’s Board of Directors declared a quarterly cash dividend of $ 0.12 per common share, which represented an increase of $ 0.02 per common share, or a 20% increase from the immediate preceding quarter’s dividend level. The dividend is payable on June 10, 2022 to shareholders of record at the close of business on May 25, 2022 . The Corporation intends to continue to pay quarterly dividends on common stock. However, the Corporation’s common stock dividends, including the declaration, timing, and amount, remain subject to consideration and approval by the Corporation’s Board Directors at the relevant times. Preferred Stock The Corporation has 50,000,000 authorized shares of preferred stock with a par value of $ 1.00, redeemable at the Corporation’s option, subject to certain terms. This stock may be issued in series and the shares of each series have such rights and preferences as are fixed by the Board of Directors when authorizing the issuance of that particular series. On November 30, 2021, the Corporation redeemed all of its 1,444,146 outstanding shares of Series A through Series E Preferred Stock for its liquidation value of $ 25 per share of $ 36.1 million. The difference between the liquidation value and net carrying value was $ 1.2 million, which was recorded as a reduction to retained earnings in 2021. The redeemed preferred stock shares were not listed on any securities exchange or automated quotation system. No shares of preferred stock were outstanding as of March 31, 2022. For the quarter ended March 31, 2021, total cash dividends declared on shares of preferred stock amounted to $ 0.7 million. Treasury stock During the first quarter of 2022, the Corporation withheld an aggregate of 201,930 shares (first quarter of 2021 - 194,471 shares) of the restricted stock and performance units that vested during the quarter to cover the officers’ payroll and income tax liabilities; these shares are held as treasury stock. Also held as treasury stock are the 3,409,697 shares of common stock repurchased in the first quarter of 2022 as part of the $ 300 million stock repurchase program authorized by the Corporation’s Board of Directors in April 2021. During the first quarter of 2022, a total of 489,085 common shares issued in connection with restricted stock and performance shares awards, were reissued from treasury shares. As of March 31, 2022 and December 31, 2021, the Corporation had 24,962,245 and 21,836,611 shares held as treasury stock, respectively. FirstBank Statutory Reserve (Legal Surplus) The Banking Law of the Commonwealth of Puerto Rico requires that a minimum of 10% of FirstBank’s net income for the year be transferred to a legal surplus reserve until such surplus equals the total of paid-in-capital on common and preferred stock. Amounts transferred to the legal surplus reserve from retained earnings are not available for distribution to the Corporation, including for payment as dividends to the stockholders, without the prior consent of the Puerto Rico Commissioner of Financial Institutions. 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. FirstBank’s legal surplus reserve, included as part of retained earnings in the Corporation’s consolidated statements of financial condition, amounted to $ 137.6 million as of each March 31, 2022 and December 31, 2021. There were no transfers to the legal surplus reserve during the quarter ended March 31, 2022.

One defined benefit pension plan covers substantially all of BSPR’s former employees who were active before January 1, 2007, while the other defined benefit pension plan covers personnel of an institution previously-acquired by BSPR. Benefits are based on salary and years of service. The accrual of benefits under the Pension Plans is frozen to all participants. The Corporation requires recognition of a plan’s overfunded and underfunded status as an asset or liability with an offsetting adjustment to accumulated other comprehensive loss pursuant to ASC Topic 715, Compensation-Retirement Benefits. The following table presents the components of net periodic benefit income for the Pension Plans and Postretirement Benefit Plan for the indicated periods: Affected Line Item in the Consolidated Statements of Income Quarter Ended March 31, 2022 March 31, 2021 (In thousands) Net periodic benefit income: Interest cost Other expenses $ 655 $ 620 Estimated return on plan assets Other expenses ( 1,039) ( 1,131) Net periodic benefit income $ ( 384) $ ( 511) The Corporation does not expect to contribute to the Pension Plans during 2022.

Income Tax Disclosure [Abstract]
INCOME TAXES [Text Block]	NOTE 18 - INCOME TAXES Income tax expense includes Puerto Rico and USVI income taxes, as well as applicable U.S. federal and state taxes. The Corporation is subject to Puerto Rico income tax on its income from all sources. As a Puerto Rico corporation, First BanCorp. is treated as a foreign corporation for U.S. and USVI income tax purposes and, accordingly, is generally subject to U.S. and USVI income tax only on its income from sources within the U.S. and USVI or income effectively connected with the conduct of a trade or business in those jurisdictions. Any such tax paid in the U.S. and USVI is also creditable against the Corporation’s Puerto Rico tax liability, subject to certain conditions and limitations. Under the Puerto Rico Internal Revenue Code of 2011, as amended (the “2011 PR Code”), the Corporation and its subsidiaries are treated as separate taxable entities and are not entitled to file consolidated tax returns and, thus, the Corporation is generally not entitled to utilize losses from one subsidiary to offset gains in another subsidiary. Accordingly, in order to obtain a tax benefit from a net operating loss (“NOL”), a particular subsidiary must be able to demonstrate sufficient taxable income within the applicable NOL carry-forward period. Pursuant to the 2011 PR Code, the carry-forward period for NOLs incurred during taxable years that commenced after December 31, 2004 and ended before January 1, 2013 is 12 years; for NOLs incurred during taxable years commencing after December 31, 2012, the carryover period is 10 years. The 2011 PR Code provides a dividend received deduction of 100% on dividends received from “controlled” subsidiaries subject to taxation in Puerto Rico and 85% on dividends received from other taxable domestic corporations. The Corporation has maintained an effective tax rate lower than the maximum statutory rate of 37.5% mainly by investing in government obligations and MBS exempt from U.S. and Puerto Rico income taxes and by doing business through an international banking entity (“an IBE”) unit of the Bank, and through the Bank’s subsidiary, FirstBank Overseas Corporation, whose interest income and gains on sales is exempt from Puerto Rico income taxation. The IBE unit and FirstBank Overseas Corporation were created under the International Banking Entity Act of Puerto Rico, which provides for total Puerto Rico tax exemption on net income derived by IBEs operating in Puerto Rico on the specific activities identified in the IBE Act. An IBE that operates as a unit of a bank pays income taxes at the corporate standard rates to the extent that the IBE’s net income exceeds 20% of the bank’s total net taxable income. For the first quarter of 2022, the Corporation recorded an income tax expense of $ 43.0 million, compared to $ 28.0 million for the same period in 2021. The variance was primarily related to higher pre-tax income and a higher estimated effective tax rate, as explained below. For the quarter ended March 31, 2022, the Corporation calculated the provision for income taxes by applying the estimated annual effective tax rate for the full fiscal year to ordinary income or loss. In the computation of the consolidated worldwide annual estimated effective tax rate, ASC Topic 740-270, “Income Taxes” (“ASC 740-270”), requires the exclusion of legal entities with pre-tax losses from which a tax benefit cannot be recognized. The Corporation’s estimated annual effective tax rate in the first quarter of 2022, excluding entities from which a tax benefit cannot be recognized and discrete items, was 32.9% compared to 30.6% for the first quarter of 2021. The estimated annual effective tax rate including all entities for 2022 was 33.2% ( 33.5% excluding discrete items), compared to 30.6% for the first quarter of 2021 ( 31.1% excluding discrete items). The Corporation’s estimated effective tax rate, excluding entities with pre-tax losses from which a tax benefit cannot be recognized and discrete items, increase is mostly attributable to a higher proportion of taxable to exempt income when compared to March 31, 2021. The Corporation’s net deferred tax asset amounted to $ 176.8 million as of March 31, 2022, net of a valuation allowance of $ 147.0 million, and management concluded, based upon the assessment of all positive and negative evidence, that it is more likely than not that the Corporation will generate sufficient taxable income within the applicable NOL carry-forward periods to realize such amount. The net deferred tax asset of the Corporation’s banking subsidiary, FirstBank, amounted to $ 176.7 million as of March 31, 2022, net of a valuation allowance of $ 107.5 million, compared to a net deferred tax asset of $ 208.4 million, net of a valuation allowance of $ 69.7 million, as of December 31, 2021. The decrease in the deferred tax assets is mainly driven by credit losses reserve releases and the usage of NOLs. The increase in the valuation allowance during the first quarter of 2022 was primarily related to the decrease in the market value of available-for-sale securities. The Corporation maintains a full valuation allowance for its deferred tax assets associated with capital loss carryforward, thus, the change in the market value of available-for-sale securities resulted in a change in the deferred tax asset and an equal change in the valuation allowance without having an effect on earnings. In 2017, the Corporation completed a formal ownership change analysis within the meaning of Section 382 of the U.S. Internal Revenue Code (“Section 382”) covering a comprehensive period and concluded that an ownership change had occurred during such period. The Section 382 limitation has resulted in higher U.S. and USVI income tax liabilities than we would have incurred in the absence of such limitation. The Corporation has mitigated to an extent the adverse effects associated with the Section 382 limitation as any such tax paid in the U.S. or USVI can be creditable against Puerto Rico tax liabilities or taken as a deduction against taxable income. However, our ability to reduce our Puerto Rico tax liability through such a credit or deduction depends on our tax profile at each annual taxable period, which is dependent on various factors. For the first quarter of 2022, the Corporation incurred an income tax expense of approximately $ 1.6 million related to its U.S. operations, compared to $ 1.1 million for the same period in 2021. The limitation did not impact the USVI operations in the first quarters of 2022 and 2021. The Corporation accounts for uncertain tax positions under the provisions of ASC Topic 740. The Corporation’s policy is to report interest and penalties related to unrecognized tax benefits in income tax expense. As of March 31, 2022, the Corporation had $ 0.2 million of accrued interest and penalties related to uncertain tax positions in the amount of $ 1.0 million that it acquired from BSPR, which, if recognized, would decrease the effective income tax rate in future periods. The amount of unrecognized tax benefits may increase or decrease in the future for various reasons, including adding amounts for current tax year positions, expiration of open income tax returns due to the statute of limitations, changes in management’s judgment about the level of uncertainty, the status of examinations, litigation, and legislative activity, and the addition or elimination of uncertain tax positions. The statute of limitations under the 2011 PR code is four years; the statute of limitations for U.S. and USVI income tax purposes is three years after a tax return is due or filed, whichever is later. The completion of an audit by the taxing authorities or the expiration of the statute of limitations for a given audit period could result in an adjustment to the Corporation’s liability for income taxes. Any such adjustment could be material to the results of operations for any given quarterly or annual period based, in part, upon the results of operations for the given period. For U.S. and USVI income tax purposes, all tax years subsequent to 2018 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2017 remain open to examination.

Fair Value Disclosures [Abstract]
FAIR VALUE [Text Block]	NOTE 19 – FAIR VALUE Fair Value Measurement The FASB authoritative guidance for fair value measurement defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This guidance also establishes a fair value hierarchy for classifying financial instruments. The hierarchy is based on whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. One of three levels of inputs may be used to measure fair value: Level 1 Valuations of Level 1 assets and liabilities are obtained from readily-available pricing sources for market transactions involving identical assets or liabilities. Level 1 assets and liabilities include equity securities that trade in an active exchange market, as well as certain U.S. Treasury and other U.S. government and agency securities and corporate debt securities that are traded by dealers or brokers in active markets. Level 2 Valuations of Level 2 assets and liabilities are based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include (i) MBS for which the fair value is estimated based on the value of identical or comparable assets, (ii) debt securities with quoted prices that are traded less frequently than exchange-traded instruments, and (iii) derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Level 3 Valuations of Level 3 assets and liabilities are based on unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined by using pricing models for which the determination of fair value requires significant management judgment as to the estimation. Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities available for sale and marketable equity securities held at fair value The fair value of investment securities was the market value based on quoted market prices (as is the case with U.S. Treasury notes, non-callable U.S. agencies debt securities, and equity securities with readily determinable fair values), when available (Level 1), or, market prices for identical or comparable assets (as is the case with MBS and callable U.S. agency debt securities) that are based on observable market parameters, including benchmark yields, reported trades, quotes from brokers or dealers, issuer spreads, bids, offers, and reference data, including market research operations, when available (Level 2). Observable prices in the market already consider the risk of nonperformance. If listed prices or quotes are not available, fair value is based upon discounted cash flow models that use unobservable inputs due to the limited market activity of the instrument, as is the case with private label MBS held by the Corporation (Level 3). Derivative instruments The fair value of most of the Corporation’s derivative instruments is based on observable market parameters and takes into consideration the credit risk component of paying counterparties, when appropriate. On interest caps, only the seller's credit risk is considered. The Corporation valued the caps using a discounted cash flow approach based on the related LIBOR and swap rate for each cash flow The Corporation valued the interest rate swaps using a discounted cash flow approach based on the related LIBOR and swap forward rate for each cash flow. The Corporation considers a credit spread for those derivative instruments that are not secured. The cumulative mark-to-market effect of credit risk in the valuation of derivative instruments for the quarters ended March 31, 2022 and 2021 was immaterial. Assets and liabilities measured at fair value on a recurring basis are summarized below as of March 31, 2022 and December 31, 2021: As of March 31, 2022 As of December 31, 2021 Fair Value Measurements Using Fair Value Measurements Using (In thousands) Level 1 Level 2 Level 3 Assets/Liabilities at Fair Value Level 1 Level 2 Level 3 Assets/Liabilities at Fair Value Assets: Securities available for sale: U.S. Treasury Securities $ 142,749 $ - $ - $ 142,749 $ 148,486 $ - $ - $ 148,486 Noncallable U.S. agencies debt securities - 323,180 - 323,180 - 285,028 - 285,028 Callable U.S. agencies debt securities and MBS - 5,948,084 - 5,948,084 - 6,009,163 - 6,009,163 Puerto Rico government obligations - - 2,727 2,727 - - 2,850 2,850 Private label MBS - - 6,920 6,920 - - 7,234 7,234 Other investments - - 1,000 1,000 - - 1,000 1,000 Equity securities 5,202 - - 5,202 5,378 - - 5,378 Derivatives, included in assets: Interest rate swap agreements - 755 - 755 - 1,098 - 1,098 Purchased interest rate cap agreements - 60 - 60 - 8 - 8 Forward contracts - 238 - 238 - - - - Interest rate lock commitments - 108 - 108 - 379 - 379 Forward loan sales commitments - 9 - 9 - 20 - 20 Liabilities: Derivatives, included in liabilities: Interest rate swap agreements - 734 - 734 - 1,092 - 1,092 Written interest rate cap agreements - 60 - 60 - 8 - 8 Forward contracts - 28 - 28 - 78 - 78 The table below presents a reconciliation of the beginning and ending balances of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the quarters ended March 31, 2022 and 2021: Quarter ended March 31, 2022 2021 Level 3 Instruments Only Securities Securities (In thousands) Available For Sale (1) Available For Sale (1) Beginning balance $ 11,084 11,977 Total gains (losses) (realized/unrealized): Included in other comprehensive income ( 287) 321 Included in earnings 388 127 Principal repayments and amortization ( 538) ( 649) Ending balance $ 10,647 $ 11,776 (1) Amounts mostly related to private label MBS. The tables below present qualitative information for significant assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of March 31, 2022 and December 31, 2021: March 31, 2022 Range Weighted Average (In thousands) Fair Value Valuation Technique Unobservable Input Minimum Maximum Investment securities available-for-sale: Private label MBS $ 6,920 Discounted cash flows Discount rate 14.3 % 14.3 % 14.3 % Prepayment rate 9.4 % 24.1 % 14.4 % Projected Cumulative Loss Rate 0.3 % 14.9 % 6.5 % Puerto Rico government obligations 2,727 Discounted cash flows Discount rate 6.3 % 8.6 % 8.4 % Projected Cumulative Loss Rate 8.8 % 8.8 % 8.8 % December 31, 2021 Range Weighted (In thousands) Fair Value Valuation Technique Unobservable Input Minimum Maximum Average Investment securities available-for-sale: Private label MBS $ 7,234 Discounted cash flows Discount rate 12.9 % 12.9 % 12.9 % Prepayment rate 7.6 % 24.9 % 15.2 % Projected Cumulative Loss Rate 0.2 % 15.7 % 7.6 % Puerto Rico government obligations 2,850 Discounted cash flows Discount rate 6.6 % 8.4 % 7.9 % Projected Cumulative Loss Rate 8.6 % 8.6 % 8.6 % Information about Sensitivity to Changes in Significant Unobservable Inputs Private label MBS : The significant unobservable inputs in the valuation include probability of default, the loss severity assumption, and prepayment rates. Shifts in those inputs would result in different fair value measurements. Increases in the probability of default, loss severity assumptions, and prepayment rates in isolation would generally result in an adverse effect on the fair value of the instruments. The Corporation modeled meaningful and possible shifts of each input to assess the effect on the fair value estimation. Puerto Rico Government Obligations : The significant unobservable input used in the fair value measurement is the assumed loss rate of the underlying residential mortgage loans that collateralize these obligations, which are guaranteed by the PRHFA. A significant increase (decrease) in the assumed rate would lead to a (lower) higher fair value estimate. The fair value of these bonds was based on a discounted cash flow methodology that considers the structure and terms of the underlying collateral. The Corporation utilizes PDs and LGDs that consider, among other things, historical payment performance, loan-to-value attributes, and relevant current and forward-looking macroeconomic variables, such as regional unemployment rates, the housing price index, and the expected recovery of PRHFA guarantee. Under this approach, all future cash flows (interest and principal) from the underlying collateral loans, adjusted by prepayments and the PDs and LGDs derived from the above-described methodology, are discounted at the internal rate of return as of the reporting date and compared to the amortized cost. The table below summarizes changes in unrealized gains and losses recorded in earnings for the quarters ended March 31, 2022 and 2021 for Level 3 assets and liabilities that were still held at the end of each period: Changes in Unrealized Losses Level 3 Instruments Only Quarter ended March 31, (In thousands) 2022 2021 Changes in unrealized losses relating to assets still held at reporting date: Provision for credit losses - (benefit) $ ( 388) $ ( 127) Additionally, fair value is used on a nonrecurring basis to evaluate certain assets in accordance with GAAP. Adjustments to fair value usually result from the application of lower-of-cost or market accounting ( e.g. , loans held for sale carried at the lower-of-cost or fair value and repossessed assets) or write-downs of individual assets ( e.g. , goodwill and loans). As of March 31, 2022, the Corporation recorded losses or valuation adjustments for assets recognized at fair value on a non-recurring basis as shown in the following table: Carrying value as of March 31, 2022 Losses recorded for the Quarter Ended March 31, 2022 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 154,875 $ ( 2,787) OREO (2) - - 42,894 ( 73) (1) Consists mainly of collateral dependent commercial and construction loans.

(2) The Corporation derived the fair values from appraisals that took into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the properties (e.g., absorption rates and net operating income of income producing properties), which are not market observable.

These include cash and cash due from banks and other short-term assets, such as FHLB stock. Certain assets, the most significant being premises and equipment, mortgage servicing rights, core deposit, and other customer relationship intangibles, are not considered financial instruments and are not included above. Accordingly, this fair value information is not intended to, and does not, represent the Corporation’s underlying value. Many of these assets and liabilities that are subject to the disclosure requirements are not actively traded, requiring management to estimate fair values. These estimates necessarily involve the use of assumptions and judgment about a wide variety of factors, including but not limited to, relevancy of market prices of comparable instruments, expected futures cash flows, and appropriate discount rates.

REVENUE FROM CONTRACTS WITH CUS

REVENUE FROM CONTRACTS WITH CUSTOMERS	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	NOTE 20 – REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition In accordance with ASC Topic 606, “Revenue from Contracts with Customers” (“ASC Topic 606”), revenues are recognized when control of promised goods or services is transferred to customers and in an amount that reflects the consideration to which the Corporation expects to be entitled in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC Topic 606, the Corporation performs the following five steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when (or as) the Corporation satisfies a performance obligation. The Corporation only applies the five-step model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Corporation assesses the goods or services that are promised within each contract, identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Corporation then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Disaggregation of Revenue The following table summarizes the Corporation’s revenue, which includes net interest income on financial instruments and non-interest income, disaggregated by type of service and business segment for the quarters ended March 31, 2022 and 2021: For the quarter ended March 31, 2022: Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total (In thousands) Net interest income (1) $ 25,779 $ 89,546 $ 40,415 $ 7,409 $ 16,482 $ 5,993 $ 185,624 Non-interest income: Service charges and fees on deposit accounts - 5,539 2,976 - 138 710 9,363 Insurance commissions - 4,967 - - 29 279 5,275 Merchant-related income - 1,822 373 - 5 389 2,589 Credit and debit card fees - 6,671 16 - ( 7) 410 7,090 Other service charges and fees 143 1,110 1,113 - 499 157 3,022 Not in scope of Topic 606 (1) 5,109 354 76 ( 112) 80 12 5,519 Total non-interest income 5,252 20,463 4,554 ( 112) 744 1,957 32,858 Total Revenue $ 31,031 $ 110,009 $ 44,969 $ 7,297 $ 17,226 $ 7,950 $ 218,482 For the quarter ended March 31, 2021: Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total (In thousands) Net interest income (1) $ 25,240 $ 58,483 $ 48,981 $ 21,583 $ 15,023 $ 6,955 $ 176,265 Non-interest income: Service charges and fees on deposit accounts - 4,476 2,971 - 149 708 8,304 Insurance commissions - 4,967 - - 29 245 5,241 Merchant-related income - 922 256 - 13 204 1,395 Credit and debit card fees - 5,645 19 - 3 370 6,037 Other service charges and fees 173 865 519 - 458 141 2,156 Not in scope of Topic 606 (1) 6,943 368 132 56 323 1 7,823 Total non-interest income 7,116 17,243 3,897 56 975 1,669 30,956 Total Revenue $ 32,356 $ 75,726 $ 52,878 $ 21,639 $ 15,998 $ 8,624 $ 207,221 (1) Most of the Corporation’s revenue is not within the scope of ASC Topic 606. The guidance explicitly excludes net interest income from financial assets and liabilities, as well as other non-interest income from loans, leases, investment securities and derivative financial instruments. For the quarters ended March 31, 2022 and 2021, substantially all of the Corporation’s revenue within the scope of ASC Topic 606 was related to performance obligations satisfied at a point in time. The following is a discussion of revenues under the scope of ASC Topic 606. Service Charges and Fees on Deposit Accounts Service charges and fees on deposit accounts relate to fees generated from a variety of deposit products and services rendered to customers. Charges include, but are not limited to, overdraft fees, insufficient fund fees, dormant fees and monthly service charges. Such fees are recognized concurrently with the event on a daily basis or on a monthly basis depending upon the customer’s cycle date. These depository arrangements are considered day-to-day contracts that do not extend beyond the services performed, as customers have the right to terminate these contracts with no penalty or, if any, no-substantive penalties. Insurance Commissions For insurance commissions, which include regular and contingent commissions paid to the Corporation’s insurance agency, the agreements contain a performance obligation related to the sale/issuance of the policy and ancillary administrative post-issuance support. The performance obligations are satisfied when the policies are issued, and revenue is recognized at that point in time. In addition, contingent commission income may be considered to be constrained, as defined under ASC Topic 606. Contingent commission income is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or payments are received. For the quarters ended March 31, 2022 and 2021, the Corporation recognized revenue at the time that payments were confirmed and constraints were released of $ 3.0 million and $ 3.3 million, respectively. Merchant-related Income For merchant-related income, the determination of which included the consideration of a 2015 sale of merchant contracts that involved sales of point of sale (“POS”) terminals and entry into a marketing alliance under a revenue-sharing agreement, the Corporation concluded that control of the POS terminals and merchant contracts was transferred to the customer at the contract’s inception. With respect to the related revenue-sharing agreement, the Corporation satisfies the marketing alliance performance obligation over the life of the contract and recognizes the associated transaction price as the entity performs and any constraints over the variable consideration are resolved. Credit and Debit Card Fees Credit and debit card fees primarily represent revenues earned from interchange fees and automated teller machine (“ATM”) fees. Interchange and network revenues are earned on credit and debit card transactions conducted with payment networks. ATM fees are primarily earned as a result of surcharges assessed to non-FirstBank customers who use a FirstBank ATM. Such fees are generally recognized concurrently with the delivery of services on a daily basis. Other Fees Other fees primarily include revenues generated from wire transfers, lockboxes, bank issuances of checks and trust fees recognized from transfer paying agent, retirement plan, and other trustee activities. Revenues are recognized on a recurring basis when the services are rendered. Contract Balances A contract liability is an entity’s obligation to transfer goods or services to a customer in exchange for consideration from the customer. During 2019, the Bank entered into a growth agreement with an international card service association to expand the customer base and enhance product offerings. The primary performance obligation of this contract required the Bank to either launch a new debit card product by 2021, or maintain a ratio of over 50% of the portfolio with the related card service association by the year ended December 31, 2021. In connection with this agreement, the Corporation recognized a contract liability as the revenue is constrained to the fulfillment of the above conditions. During the third quarter of 2021, the Bank successfully launched the new debit card product required and recognized revenues of $ 0.4 million from this contract. In addition, as discussed above, during 2015, the Bank entered into a long-term strategic marketing alliance under a revenue-sharing agreement with another entity to which the Bank sold its merchant contracts portfolio and related POS terminals. Merchant services are marketed through the Bank’s branches and offices in Puerto Rico and the Virgin Islands. Under the revenue-sharing agreement, FirstBank shares with this entity revenues generated by the merchant contracts over the term of the 10-year agreement. As of March 31, 2022 and 2021, this contract liability amounted to $ 1.0 million and $ 1.3 million, respectively, which will be recognized over the remaining term of the contract. For the quarters ended March 31, 2022 and 2021, the Corporation recognized revenue and its contract liabilities decreased by approximately $ 0.3 million and $ 0.1 million, respectively, due to the completion of performance over time. There were no changes in contract liabilities due to changes in transaction price estimates. A contract asset is the right to consideration for transferred goods or services when the amount is conditioned on something other than the passage of time. As of March 31, 2022 and 2021, there were no contract assets from contracts with customers or contract assets recorded on the Corporation’s consolidated financial statements. The following table shows the activity of contract liabilities for the quarters ended March 31, 2022 and 2021: (In thousands) March 31, 2022 March 31, 2021 Beginning Balance $ 1,443 $ 2,151 Less: Revenue recognized ( 289) ( 81) Ending balance $ 1,154 $ 2,070 Other Except for the contract liabilities noted above, the Corporation did not have any significant performance obligations as of March 31, 2022. The Corporation also did not have any material contract acquisition costs and did not make any significant judgments or estimates in recognizing revenue for financial reporting purposes.

Segment Reporting [Abstract]
SEGMENT INFORMATION [Text Block]	NOTE 22 – SEGMENT INFORMATION Based upon the Corporation’s organizational structure and the information provided to the Chief Executive Officer, the operating segments are based primarily on the Corporation’s lines of business for its operations in Puerto Rico, the Corporation’s principal market, and by geographic areas for its operations outside of Puerto Rico. As of March 31, 2022, the Corporation had six reportable segments: Commercial and Corporate Banking; Mortgage Banking; Consumer (Retail) Banking; Treasury and Investments; United States Operations; and Virgin Islands Operations. Management determined the reportable segments based on the internal structure used to evaluate performance and to assess where to allocate resources. Other factors, such as the Corporation’s organizational chart, nature of the products, distribution channels, and the economic characteristics of the products, were also considered in the determination of the reportable segments. The Commercial and Corporate Banking segment consists of the Corporation’s lending and other services for large customers represented by specialized and middle-market clients and the public sector. The Commercial and Corporate Banking segment offers commercial loans, including commercial real estate and construction loans, and floor plan financings, as well as other products, such as cash management and business management services. The Mortgage Banking segment consists of the origination, sale, and servicing of a variety of residential mortgage loans. The Mortgage Banking segment also acquires and sells mortgages in the secondary markets. In addition, the Mortgage Banking segment includes mortgage loans purchased from other local banks and mortgage bankers. The Consumer (Retail) Banking segment consists of the Corporation’s consumer lending and deposit-taking activities conducted mainly through its branch network and loan centers. The Treasury and Investments segment is responsible for the Corporation’s investment portfolio and treasury functions that are executed to manage and enhance liquidity. This segment lends funds to the Commercial and Corporate Banking, Mortgage Banking, Consumer (Retail) Banking, and United States Operations segments to finance their lending activities and borrows from those segments. The Consumer (Retail) Banking segment also lends funds to other segments. The interest rates charged or credited by the Treasury and Investments and the Consumer (Retail) Banking segments are allocated based on market rates. The difference between the allocated interest income or expense and the Corporation’s actual net interest income from centralized management of funding costs is reported in the Treasury and Investments segment. The United States Operations segment consists of all banking activities conducted by FirstBank in the United States mainland, including commercial and consumer banking services. The Virgin Islands Operations segment consists of all banking activities conducted by the Corporation in the USVI and BVI, including commercial and consumer banking services. The accounting policies of the segments are the same as those referred to in Note 1 – Nature of Business and Summary of Significant Accounting Policies, in the audited consolidated financial statements, which are included in the 2021 Annual Report on Form 10-K. The Corporation evaluates the performance of the segments based on net interest income, the provision for credit losses, non-interest income and direct non-interest expenses. The segments are also evaluated based on the average volume of their interest-earning assets less the ACL. The following table presents information about the reportable segments for the quarters ended March 31, 2022 and 2021: (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Banking Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended March 31, 2022: Interest income $ 33,071 $ 70,437 $ 47,027 $ 22,184 $ 18,857 $ 6,278 $ 197,854 Net (charge) credit for transfer of funds ( 7,292) 24,282 ( 6,612) ( 9,949) ( 429) - - Interest expense - ( 5,173) - ( 4,826) ( 1,946) ( 285) ( 12,230) Net interest income 25,779 89,546 40,415 7,409 16,482 5,993 185,624 Provision for credit losses - (benefit) expense ( 3,703) 11,144 ( 16,622) ( 388) ( 3,547) ( 686) ( 13,802) Non-interest income 5,252 20,463 4,554 ( 112) 744 1,957 32,858 Direct non-interest expenses 6,906 39,271 8,859 885 8,479 6,973 71,373 Segment income $ 27,828 $ 59,594 $ 52,732 $ 6,800 $ 12,294 $ 1,663 $ 160,911 Average earning assets $ 2,293,648 $ 2,759,482 $ 3,664,104 $ 8,145,949 $ 2,065,638 $ 378,169 $ 19,306,990 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Banking Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended March 31, 2021: Interest income $ 37,060 $ 65,733 $ 51,458 $ 12,762 $ 20,332 $ 7,297 $ 194,642 Net (charge) credit for transfer of funds ( 11,820) 1,055 ( 2,477) 14,934 ( 1,692) - - Interest expense - ( 8,305) - ( 6,113) ( 3,617) ( 342) ( 18,377) Net interest income 25,240 58,483 48,981 21,583 15,023 6,955 176,265 Provision for credit losses expense ( 786) 3,962 ( 17,179) ( 127) ( 237) ( 885) ( 15,252) Non-interest income 7,116 17,243 3,897 56 975 1,669 30,956 Direct non-interest expenses 7,997 41,091 11,538 1,234 8,294 7,405 77,559 Segment (loss) income $ 25,145 $ 30,673 $ 58,519 $ 20,532 $ 7,941 $ 2,104 $ 144,914 Average earning assets $ 2,658,887 $ 2,442,174 $ 4,029,377 $ 6,259,344 $ 2,078,660 $ 449,532 $ 17,917,974 The following table presents a reconciliation of the reportable segment financial information to the consolidated totals for the indicated periods: Quarter Ended March 31, (In thousands) 2022 2021 Net income: Total income for segments $ 160,911 $ 144,914 Other operating expenses (1) 35,286 55,742 Income before income taxes 125,625 89,172 Income tax expense 43,025 28,022 Total consolidated net income $ 82,600 $ 61,150 Average assets: Total average earning assets for segments $ 19,306,990 $ 17,917,974 Average non-earning assets 947,011 1,168,336 Total consolidated average assets $ 20,254,001 $ 19,086,310 (1) Expenses pertaining to corporate administrative functions that support the operating segment, but are not specifically attributable to or managed by any segment, are not included in the reported financial results of the operating segments.

Commitments and Contingencies Disclosure [Abstract]
REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES [Text Block]	NOTE 23 – REGULATORY MATTERS, COMMITMENTS, AND CONTINGENCIES The Corporation and FirstBank are each subject to various regulatory capital requirements imposed by the U.S. federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on the Corporation’s financial statements and activities. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation must meet specific capital guidelines that involve quantitative measures of the Corporation’s and FirstBank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Corporation’s capital amounts and classification are also subject to qualitative judgments and adjustment by the regulators with respect to minimum capital requirements, components, risk weightings, and other factors. As of March 31, 2022 and December 31, 2021, the Corporation and FirstBank exceeded the minimum regulatory capital ratios for capital adequacy purposes and FirstBank exceeded the minimum regulatory capital ratios to be considered a well capitalized institution under the regulatory framework for prompt corrective action. As of March 31, 2022, management does not believe that any condition has changed or event has occurred that would have changed the institution’s status. The Corporation and FirstBank compute risk-weighted assets using the standardized approach required by the U.S. Basel III capital rules (“Basel III rules”). The Basel III rules require the Corporation to maintain an additional capital conservation buffer of 2.5% on certain regulatory capital ratios to avoid limitations on both (i) capital distributions ( e.g. , repurchases of capital instruments, dividends and interest payments on capital instruments) and (ii) discretionary bonus payments to executive officers and heads of major business lines. As part of its response to the impact of COVID-19, on March 31, 2020, the federal banking agencies issued an interim final rule that provided the option to temporarily delay the effects of CECL on regulatory capital for two years, followed by a three-year transition period. The interim final rule provides that, at the election of a qualified banking organization, the day one impact to retained earnings plus 25% of the change in the ACL (as defined in the interim final rule) from January 1, 2020 to December 31, 2021 will be delayed for two years and phased-in at 25% per year beginning on January 1, 2022 over a three-year period, resulting in a total transition period of five years. Accordingly, as of March 31, 2022, the capital measures of the Corporation and the Bank included $ 16.2 million associated with the CECL day one impact to retained earnings plus 25% of the increase in the ACL (as defined in the interim final rule) from January 1, 2020 to December 31, 2021, and $ 48.6 million remains excluded to be phase-in during the next two years. The federal financial regulatory agencies may take other measures affecting regulatory capital to address the COVID-19 pandemic, although the nature and impact of such actions cannot be predicted at this time. The regulatory capital positions of the Corporation and FirstBank as of March 31, 2022 and December 31, 2021, which reflect the delay in the effect of CECL on regulatory capital, were as follows: Regulatory Requirements Actual For Capital Adequacy Purposes To be Well-Capitalized Thresholds Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) As of March 31, 2022 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 2,428,930 20.44% $ 950,603 8.0% N/A N/A FirstBank $ 2,395,864 20.17% $ 950,418 8.0% $ 1,188,022 10.0% CET1 Capital (to Risk-Weighted Assets) First BanCorp. $ 2,103,970 17.71% $ 534,714 4.5% N/A N/A FirstBank $ 2,149,154 18.09% $ 534,610 4.5% $ 772,214 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 2,103,970 17.71% $ 712,952 6.0% N/A N/A FirstBank $ 2,249,154 18.93% $ 712,813 6.0% $ 950,418 8.0% Leverage ratio First BanCorp. $ 2,103,970 10.35% $ 813,172 4.0% N/A N/A FirstBank $ 2,249,154 11.07% $ 812,893 4.0% $ 1,016,117 5.0% As of December 31, 2021 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 2,433,953 20.50% $ 949,637 8.0% N/A N/A FirstBank $ 2,401,390 20.23% $ 949,556 8.0% $ 1,186,944 10.0% CET1 Capital (to Risk-Weighted Assets) First BanCorp. $ 2,112,630 17.80% $ 534,171 4.5% N/A N/A FirstBank $ 2,150,317 18.12% $ 534,125 4.5% $ 771,514 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 2,112,630 17.80% $ 712,228 6.0% N/A N/A FirstBank $ 2,258,317 19.03% $ 712,167 6.0% $ 949,556 8.0% Leverage ratio First BanCorp. $ 2,112,630 10.14% $ 833,091 4.0% N/A N/A FirstBank $ 2,258,317 10.85% $ 832,773 4.0% $ 1,040,967 5.0% The Corporation enters into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments may include commitments to extend credit and standby letters of credits. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses. Since certain commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. For most of the commercial lines of credit, the Corporation has the option to reevaluate the agreement prior to additional disbursements. In the case of credit cards and personal lines of credit, the Corporation can cancel the unused credit facility at any time and without cause. As of March 31, 2022, commitments to extend credit amounted to approximately $ 2.1 billion, of which $ 1.2 billion relates to credit card loans. Commercial and financial standby letters of credit amounted to approximately $ 151.4 million. As of March 31, 2022, First BanCorp. and its subsidiaries were defendants in various legal proceedings, claims, and other loss contingencies arising in the ordinary course of business. On at least a quarterly basis, the Corporation assesses its liabilities and contingencies in connection with threatened and outstanding legal proceedings, claims, and other loss contingencies utilizing the latest information available. For legal proceedings, claims, and other loss contingencies where it is both probable that the Corporation will incur a loss and the amount can be reasonably estimated, the Corporation establishes an accrual for the loss. Once established, the accrual is adjusted as appropriate to reflect any relevant developments. For legal proceedings, claims, and other loss contingencies where a loss is not probable or the amount of the loss cannot be estimated, no accrual is established. Any estimate involves significant judgment, given the varying stages of the proceedings (including the fact that some of them are currently in preliminary stages), the existence in some of the current proceedings of multiple defendants whose share of liability has yet to be determined, the numerous unresolved issues in the proceedings, and the inherent uncertainty of the various potential outcomes of such proceedings. Accordingly, the Corporation’s estimate will change from time-to-time, and actual losses may be more or less than the current estimate. While the final outcome of legal proceedings, claims, and other loss contingencies is inherently uncertain, based on information currently available, management believes that the final disposition of the Corporation’s legal proceedings, claims, and other loss contingencies, to the extent not previously provided for, will not have a material adverse effect on the Corporation’s consolidated financial position as a whole. If management believes that, based on available information, it is at least reasonably possible that a material loss (or material loss in excess of any accrual) will be incurred in connection with any legal contingencies, the Corporation discloses an estimate of the possible loss or range of loss, either individually or in the aggregate, as appropriate, if such an estimate can be made, or discloses that an estimate cannot be made. Based on the Corporation’s assessment as of March 31, 2022, no such disclosures were necessary.

Accounting Standards Update and Change in Accounting Principle [Table Text Block]	Standard Description Effective Date Effect on the financial statements ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” In March 2022, the FASB issued ASU 2022-02 which eliminates the troubled debt restructurings (“TDRs”) recognition and measurement guidance, enhances disclosure requirements for loan restructurings by creditors made to borrowers experiencing financial difficulty for which the terms of the receivables have been modified, and amends the guidance on vintage disclosures to require disclosure of gross write-offs by year of origination. January 1, 2023, unless early adopted in which case the amendments should be applied as of the beginning of the fiscal year that includes the interim period The Corporation is evaluating the impact that this ASU will have on its financial statements and disclosures. The Corporation expects to adopt the amendments of this update during the first quarter of 2023 using a modified retrospective transition method to adjust the ACL for loans modified as a TDR prior to the adoption of these amendments. ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method” In March 2022, the FASB issued ASU 2022-01 which, among others, expands the current last-of-layer method to allow multiple hedged layers and the scope of the portfolio layer method to non-prepayable financial assets. January 1, 2023, unless early adopted in which case the amendments should be applied as of the beginning of the fiscal year that includes the interim period The Corporation does not expect to be impacted by the amendments of this update since it does not apply fair value hedge accounting to any of its derivatives.

Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]	The Corporation commences the foreclosure process on residential real estate loans when a borrower becomes 120 days delinquent, in accordance with the requirements of the Consumer Financial Protection Bureau (“CFPB”). Foreclosure procedures and timelines vary depending on whether the property is located in a judicial or non-judicial state. Judicial states ( i.e ., Puerto Rico, Florida and the USVI) require the foreclosure to be processed through the state’s court while foreclosure in non-judicial states ( i.e., the BVI) is processed without court intervention. Foreclosure timelines vary according to local jurisdiction law and investor guidelines. Occasionally, foreclosures may be delayed due to, among other reasons, mandatory mediations, bankruptcy, court delays, and title issues.

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.

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.
