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 included in the 2019 Annual Report on Form 10-K and accounting policies affected by the adoption, on January 1, 2020, of Accounting Standards Update No. (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, as amended (“ASC 326”), as further described below. 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 of the Corporation for the year ended December 31, 2019, which are included in the 2019 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, 2020 are not necessarily indicative of the results to be expected for the entire year. Risks and Uncertainties related to COVID-19 On March 11, 2020, the outbreak of COVID-19 (coronavirus) caused by a novel strain of the coronavirus was recognized as a pandemic by the World Health Organization, and since then has widely spread to many countries, including in the markets in which the Corporation operates. The COVID-19 pandemic has severely restricted the level of economic activity in the Corporation’s markets. In response to the COVID-19 pandemic, the Puerto Rico’s Governor issued a stay-at-home order on March 15, 2020, which she subsequently extended until May 3, 2020. In addition to mandating that every citizen stay at home except for certain essential activities, the order set out a nightly curfew and a lockdown of non-essential businesses. Since March 31, 2020, the governor instituted additional restrictive measures, including limiting travel by car, the use of protective equipment, such as masks, the maintenance of a distance of at least six feet between citizens, and a curfew between 7 p.m. to 5 a.m. Although some of these restrictions have been modified, the full lockdown of non-essential businesses continued until May 3, 2020 and the stay-at-home order and the curfew was extended until May 25, 2020. On May 1, 2020, Puerto Rico’s Governor announced a gradual reopening of the economy, allowing the reopening on May 4, 2020 of sectors such as mortgage financial services, insurance, and professional services including lawyers, engineers, accountants and dental offices. On May 11, 2020, the construction and manufacturing sectors will be allowed to resume operations. Other sectors, such as retail trade and auto sales, are expected to be allowed to reopen in mid to late May 2020, depending on how the COVID-19 trends in Puerto Rico cases develop over the upcoming weeks. As of May 2, 2020, 1,757 people in 73 municipalities in Puerto Rico had tested positive for COVID-19 and 95 people’ deaths were related to the illness, according to data provided by the Puerto Rico government. The Corporation’s businesses in the other jurisdictions in which it operates have also been adversely affected. On March 26, 2020 the Florida Governor issued a stay-at-home order, and the state is expected to reopen essential operations through a phase-in process beginning on May 4, 2020. Additionally, in the U.S. Virgin Islands, the government issued a stay-at-home order on March 23, 2020, and the territory announced a plan for a phased reopening of non-essential businesses beginning on May 4, 2020. The Corporation’s business, financial condition and results of operations generally rely upon the ability of the Corporation’s borrowers to repay their loans, the value of collateral underlying the Corporation’s secured loans, and demand for loans and other products and services the Corporation offers, which are highly dependent on the business environment in the Corporation’s primary markets where it operates. Governments globally intervened with fiscal policy to mitigate the impact, including the Coronavirus Aid, Relief, and Economic Security (CARES) Act in the U.S., which aimed to provide economic relief to businesses and individuals. Some of these provisions may improve the ability of impacted borrowers to pay their loans, including direct cash payments to eligible taxpayers below specified income limits, including Puerto Rico residents, expanded unemployment insurance benefits and eligibility, and relief designed to prevent layoffs and business closures at small businesses. In addition, the Puerto Rico Government and the PROMESA oversight board has allocated more than $900 million aimed to stimulate the Puerto Rico economy and provide cash flow relief to those affected by the COVID-19 pandemic. The COVID-19 pandemic, and governmental, regulatory authorities, and societal responses have also affected the Corporation’s financial results. The COVID-19 pandemic and its associated impacts on trade (including supply chains and export levels), travel, underemployment and unemployment, consumer spending, residential and commercial construction and other economic activities has resulted in less economic activity, lower equity market valuations and significant volatility and disruption in financial markets. For instance, on March 3, 2020, the Federal Reserve reduced the target federal funds rate by 50 basis points, followed by an additional reduction of 100 basis points on March 16, 2020. These reductions in interest rates and economic uncertainties, as a result of the spread of COVID-19, have adversely affected and might further adversely affect the Corporation’s results of operations. The Corporation may experience other financial impacts, though such potential impacts are unknown at this time. Financial results for the quarter ended March 31, 2020 included the effect of a reserve build of $ 59.8 million ( i.e. , the amount by which the provision for credit losses of $ 77.4 million exceeds net charge-offs of $ 17.6 million), driven by the effect of the COVID-19 pandemic on forecasted economic conditions considered for the determination of the Allowance for Credit Losses (“ACL”), as further discussed below. In addition to the impact of COVID-19 on the Corporation’s ACL, the COVID-19 pandemic and the various stay-at-home and lockdown orders have resulted in a reduction of the Corporation’s transaction fee income, such as that from credit and debit cards, automated teller machines (ATMs), and point-of-sale transactions, as well as the Corporation’s volume of loan originations and closings. In working with borrowers affected by the COVID-19 pandemic, the Corporation implemented payment deferral programs to alleviate the hardships being experienced by the Corporation’s borrowers. The payment deferral programs, which the Corporation implemented in March 2020, provided deferred repayment arrangements across-the-board up to June 30, 2019 to consumer borrowers ( i.e. , residential mortgage, personal loans, auto loans, finance leases, small loans, and credit cards) who qualify for the program based, among other things, on the delinquency status of the loan on March 16, 2019, and who did not make their payment corresponding to the month of March, with the possibility of extension up to August 31, 2020, if needed. For commercial loans, any request for payment deferral is analyzed on a case by case basis. 7,064 residential mortgage loans totaling $ 931.5 million, 93,629 consumer loans totaling $ 1.0 billion, and 741 commercial and construction loans totaling $ 1.8 billion. In accordance with interagency guidance issued in March 2020, these short-term deferrals are not considered troubled debt restructurings (“TDRs”) unless the borrower was previously experiencing financial difficulty and the concession granted was considered significant in relation to the exposure, based on criteria established in Accounting Standards Codification (“ASC”) Subtopic 310-40. In addition, the risk-rating on COVID-19 modified loans did not change, and these loans will not be considered past due after the deferral period if the borrowers resume their scheduled payments. The credit quality of these loans will be reevaluated after the deferral period ends. In addition, as a certified Small Business Administration (“SBA”) lender, the Corporation is participating in the SBA Paycheck Protection Program (“PPP”) to help provide loans to the Corporation’s small business customers to provide them with additional working capital. As of May 7, 2020, the Corporation has received approval from the SBA for 3,792 applications received since April 3, 2020, the first date on which small business customers could apply for such loans, totaling approximately $ 350.6 million, of which approximately $ 313.2 million has already been funded. As of March 31, 2020, the Corporation’s and the Bank’s capital ratios were well in excess of all regulatory requirements and the Corporation maintains high liquidity levels with the cash and liquid securities total assets ratio exceeding 17.5%, compared to 15.8% as of December 31, 2019. As of May 7, 2020, the Corporation has approximately $ 383.7 million in available unused lines at the Federal Home Loan Bank, and the Primary Credit FED Discount Window Program has been activated as an alternate source of liquidity with approximately $ 973.2 million of availability, if needed. While most industries have and will continue to experience adverse impacts as a result of the COVID-19 pandemic in the immediate future, higher increases in the allowance for credit losses were made for loans in the accommodation, retail real estate, and transportation industries. The exposure to these industries represents approximately 28% of the total construction and commercial loan portfolio as of March 31, 2020. We continue to monitor unfunded commitments through the pandemic, for evidence of increased credit exposure as borrowers utilize these lines for liquidity, however, the amount of draws has not increased significantly due to the COVID-19 pandemic. The ultimate extent of the impact of the COVID-19 pandemic on the Corporation’s business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including, among others, the duration and scope of the pandemic, as well as governmental, regulatory and private sector responses to the pandemic, and the associated impacts on the economy, financial markets and our clients, employees and vendors. Adoption of New Accounting Requirements and Recently Issued but Not Yet Effective Accounting Requirements Accounting for Financial Instruments – Credit Losses On January 1, 2020, the Corporation adopted ASC 326, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology to estimate the allowance for credit losses (the “ACL”) for the remaining estimated life of certain financial assets. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loans held for investment and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance ( e.g., unfunded loan commitments, standby letters of credit, financial guarantees, and other similar instruments). In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities that management does not intend to sell or believes that it is more likely than not they will not be required to sell. The Corporation adopted ASC 326 using the modified retrospective method for financial assets measured at amortized cost, including loans held for investment and held-to-maturity debt securities, and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP . The following table illustrates the transition adjustment impact of ASC 326: (In thousands) January 1, 2020 ACL Under ASC 326 Pre-ASC 326 Impact of ASC 326 Adoption Date Adoption Adoption Assets: ACL on debt securities held to maturity $ 8,134 $ - $ 8,134 ACL on Loans and Finance Leases Residential mortgage loans $ 94,643 $ 44,806 $ 49,837 Commercial mortgage loans 19,888 39,194 ( 19,306) Commercial and Industrial loans 29,929 15,198 14,731 Construction loans 3,167 2,370 797 Consumer loans 88,677 53,571 35,106 Total ACL on loans and finance leases 236,304 155,139 81,165 Liabilities: ACL on off-balance sheet credit exposure $ 3,922 $ - $ 3,922 Pre-tax effect in beginning retained earnings $ 248,360 $ 155,139 $ 93,221 Balance sheet reclassification (1) 434 Tax effect $ ( 31,333) After-tax effect in beginning retained earnings $ 62,322 Reflects the effect of the release of the excess of the previously-established ACL for loans purchased with credit deterioration (“PCD”) over the ACL determined for such loans following the CECL methodology, which resulted in a corresponding decrease to loans. The Corporation adopted ASC 326 using the prospective transition approach for PCD loans that were previously classified as purchased credit impaired (“PCI”) loans and accounted for under ASC Topic 310-30 (ASC 310-30). As allowed by ASC 326, the Corporation elected to maintain pools of loans accounted for under ASC 310-30 as “units of accounts,” conceptually treating each pool as a single asset. As of March 31, 2020, such PCD loans consisted of $ 131.5 million of residential mortgage loans and $ 2.5 million of commercial mortgage loans acquired by the Corporation as part of previously completed asset acquisitions. These previous transactions include a transaction closed on February 27, 2015, in which FirstBank acquired 10 Puerto Rico branches of Doral Bank, acquired certain assets, including PCD loans, and assumed deposits, through an alliance with Banco Popular of Puerto Rico, which was the successful lead bidder with the FDIC on the failed Doral Bank, as well as other co-bidders, and the acquisition from Doral Financial in the first quarter of 2014 of all of its rights, title and interest in first and second residential mortgage loans in full satisfaction of secured borrowings owed by such entity to FirstBank. As the Corporation is electing to maintain pools of units of account for loans previously accounted for under ASC 310-30, the Corporation is not able to remove loans from the pools until they are paid off, written off or sold (consistent with the previous practice), but is required to follow ASC 326 for purposes of ACL. Regarding interest income recognition, the prospective transition approach for PCD loans was applied at a pool level, which froze the effective interest rate of the pools as of January 1, 2020. According to regulatory guidance, the determination of nonaccrual or accrual status for PCD loans that the Corporation has elected to maintain in previously existing pools pursuant to the policy election right upon adoption of ASC 326 should be made at the pool level, not the individual asset level. In addition, the guidance provides that the Corporation can continue accruing interest and not report the PCD loans as being in nonaccrual status if the following criteria are met: (i) the Corporation can reasonably estimate the timing and amounts of cash flows expected to be collected, and (ii) the Corporation did not acquire the asset primarily for the rewards of ownership of the underlying collateral, such as use of collateral in operations or improving the collateral for resale. Thus, the Corporation continues to exclude these pools of PCD loans from nonaccrual loan statistics. In accordance with ASC 326, the Corporation did not reassess whether modifications to individual acquired loans accounted for within pools were TDR as of the date of adoption. The Corporation adopted ASC 326 using the prospective transition approach for debt securities for which other-than-temporary impairment (“OTTI”) had been recognized prior to January 1, 2020, such as available-for-sale private label mortgage-backed securities (“MBS”). As a result, the amortized cost basis for such debt securities remains the same before and after the effective date of ASC 326. The effective interest rate on these debt securities was not changed. Amounts previously recognized in accumulated other comprehensive income (“OCI”) as of January 1, 2020 relating to improvements in cash flows expected to be collected will be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after January 1, 2020 will be recorded in earnings when received. Significant Accounting Policies affected by the adoption of ASC 326 Investment securities : The Corporation classifies its investments in debt and equity securities into one of four categories: Held-to-maturity — Securities that the entity has the intent and ability to hold to maturity. These securities are carried at amortized cost. The Corporation may not sell or transfer held-to-maturity securities without calling into question its intent to hold other debt securities to maturity, unless a nonrecurring or unusual event that could not have been reasonably anticipated has occurred. Trading — Securities that are bought and held principally for the purpose of selling them in the near term. These securities are carried at fair value, with unrealized gains and losses reported in earnings. As of March 31, 2020 and December 31, 2019, the Corporation did not hold investment securities for trading purposes. Available-for-sale — Securities not classified as held-to-maturity or trading. These securities are carried at fair value, with unrealized holding gains and losses, net of deferred taxes, reported in OCI as a separate component of stockholders’ equity. The unrealized holding gains and losses, do not affect earnings until they are realized, or an ACL is recorded. Equity securities — Equity securities that do not have readily available fair values are classified as equity securities in the consolidated statements of financial condition. These securities are stated at the lower of cost or realizable value. This category is principally composed of FHLB stock that is owned by the Corporation to comply with FHLB regulatory requirements. The realizable value of the stock equals its cost. Also included in this category are marketable equity securities held at fair value with changes in unrealized gains or losses recorded through earnings pursuant to the requirements of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. Premiums and discounts on debt securities are amortized as an adjustment to interest income on investments over the life of the related securities under the interest method without anticipating prepayments, except for MBS where prepayments are anticipated. Premiums on callable debt securities, if any, are amortized to the earliest call date. Purchases and sales of securities are recognized on a trade-date basis. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on non-accrual is reversed against interest income. No debt security is in nonaccrual status as of March 31, 2020 and December 31, 2019. Allowance for Credit Losses – Held-to-Maturity Debt Securities : The Corporation measures expected credit losses on held-to-maturity securities by major security type. As of March 31, 2020, the held-to-maturity securities portfolio consisted of Puerto Rico municipal bonds totaling $ 138.5 million. Approximately 70% of the held-to-maturity municipal bonds were issued by three of the largest municipalities in Puerto Rico. The vast majority of revenues of these three municipalities is independent of the Puerto Rico central government. These obligations typically are not issued in bearer form, nor are they registered with the SEC, and are not rated by external credit agencies. In most cases, these bonds have priority over the payment of operating costs and expenses of the municipality, which are required by law to levy special property taxes in such amounts as are required for the payment of all of their respective general obligation bonds and loans. Accrued interest receivable on held-to-maturity debt securities totaled $ 1.9 million at March 31, 2020 ($ 3.9 million as of December 31, 2019) and is excluded from the estimate of credit losses. The ACL for the held-to-maturity Puerto Rico municipal bonds ($ 9.3 million as of March 31, 2020) considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. These financing arrangements with Puerto Rico municipalities were issued in bond form and accounted for as securities but underwritten as loans with features that are typically found in commercial loans. Accordingly, similar to commercial loans, an internal risk rating ( i.e ., pass, special mention, substandard, doubtful, loss) is assigned to each bond at the time of issuance and monitored on a continuous basis with a formal assessment completed, at a minimum, on a quarterly basis. The ACL for held-to-maturity Puerto Rico municipal bonds is determined based on the product of a cumulative probability of default (PD) and loss given default (LGD), and the amortized cost basis of each bond over its remaining expected life. PD estimates represent the point-in-time as of which the PD is developed, updated quarterly based on, among other things, the payment performance experience, financial performance and market value indicators, and current and forecasted relevant forward-looking macroeconomic variables over the expected life of the bonds to determine a lifetime term structure PD curve. LGD estimates are determined based on, among other things, historical charge-off events and recovery payments (if any), government sector historical loss experience, as well as relevant current and forecasted macroeconomic expectations of variables, such as unemployment rates, interest rates, and market risk factors based on industry performance, to determine a lifetime term structure LGD curve. Under this approach, all future periods losses for each instrument are calculated using the PDs and LGDs loss rates derived from the term structure curves applied to the amortized cost basis of each bond. For the relevant macroeconomic expectations of variables, the methodology considers an initial forecast period (“reasonable and supportable period”) of 2 years and a reversion period of up to 3 years, utilizing a straight-line approach and reverting back to the historical macroeconomic mean. After the reversion period, a historical loss forecast period covering the remaining contractual life is used based on the changes in key historical economic variables during representative historical expansionary and recessionary periods. Refer to Note 5 - Investment Securities for additional information about reserve balances for held-to-maturity debt securities, activity during the period, and information about changes in circumstances that caused changes in the ACL for held-to-maturity debt securities during the first quarter of 2020. Allowance for Credit Losses – Available-for-Sale Debt Securities : For available-for-sale debt securities in an unrealized loss position, the Corporation first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written off to fair value through income. For available-for-sale debt securities that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the cash position of the issuer and its cash and capital generation capacity, which could increase or diminish the issuer’s ability to repay its bond obligations, the extent to which the fair value is less than the amortized cost basis, any adverse change to the credit conditions and liquidity of the issuer, taking into consideration the latest information available about the financial condition of the issuer, credit ratings, the failure of the issuer to make scheduled principal or interest payments, recent legislation and government actions affecting the issuer’s industry, and actions taken by the issuer to deal with the economic climate. The Corporation also takes into consideration changes in the near-term prospects of the underlying collateral of a security, if any, such as changes in default rates, loss severity given default, and significant changes in prepayment assumptions and the level of cash flows generated from the underlying collateral, if any, supporting the principal and interest payments on the debt securities. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount by which the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in OCI. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. The ACL for available-for-sale securities as of March 31, 2020 amounted to $ 0.3 million. Available-for-sale debt securities held by the Corporation at quarter-end primarily consisted of securities issued by U.S. government-sponsored entities (“GSEs”), private label MBS, and certain bonds issued by the Puerto Rico Housing Finance Authority (“PRHFA”), a government instrumentality of the Commonwealth of Puerto Rico. Given the explicit and implicit guarantees provided by the U.S. federal government, the Corporation believes the credit risk in securities issued by the GSEs is low. The Corporation’s credit loss-impairment assessment was concentrated on private label MBS and PRHFA debt securities. For further information, including the methodology and assumptions used for the discounted cash flow analyses performed on private label MBS, refer to Notes 5 – Investment Securities and Note 24 – Fair Value to the consolidated financial statements. Accrued interest receivable on available-for-sale debt securities totaled $ 5.6 million as of March 31, 2020 ($ 5.5 million as of December 31, 2019) and is excluded from the estimate of credit losses. Loans Held for Investment : Loans that the Corporation has the ability and intent to hold for the foreseeable future are classified as held for investment and are reported at amortized cost, net of the allowance for credit losses. The substantial majority of the Corporation’s loans are classified as held for investment. Amortized cost is the principal outstanding balance, net of unearned interest, cumulative charge-offs, unamortized deferred origination fees and costs, and unamortized premiums and discounts. Credit card loans are reported at their outstanding unpaid principal balance plus uncollected billed interest and fees net of such amounts deemed uncollectible. Accrued interest receivable on loans totaled $ 40.0 million as of March 31, 2020 ($ 39.1 million as of December 31, 2019), is reported as part of accrued interest receivable on loans and investment securities in the consolidated statements of financial condition, and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Fees collected and costs incurred in the origination of new loans are deferred and amortized using the interest method or a method that approximates the interest method over the term of the loan as an adjustment to interest yield. Unearned interest on certain personal loans, auto loans and finance leases and discounts and premiums are recognized as income under a method that approximates the interest method. When a loan is paid-off or sold, any unamortized net deferred fee (cost) is credited (charged) to income. Nonaccrual and Past-Due Loans - Loans on which the recognition of interest income has been discontinued are designated as nonaccrual. Loans are classified as nonaccrual when they are 90 days past due for interest and principal, with the exception of residential mortgage loans guaranteed by the Federal Housing Administration (the “FHA”), the Veterans Administration (the “VA”) or the PRHFA and credit card loans. It is the Corporation’s policy to report delinquent mortgage loans insured by the FHA, or guaranteed by the VA or the PRHFA, as loans past due 90 days and still accruing as opposed to nonaccrual loans since the principal repayment is insured. However, the Corporation discontinues the recognition of income relating to FHA/VA loans when such loans are over 15 months delinquent, taking into consideration the FHA interest curtailment process, and whether PRHFA loans are over 90 days delinquent. Credit card loans continue to accrue finance charges and fees until charged off at 180 days. Loans generally may be placed on nonaccrual status prior to when required by the policies described above when the full and timely collection of interest or principal becomes uncertain (generally based on an assessment of the borrower’s financial condition and the adequacy of collateral, if any). When a loan is placed on nonaccrual status, any accrued but uncollected interest income is reversed and charged against interest income and amortization of any net deferred fees is suspended. The amount of accrued interest reversed against interest income totaled $ 0.5 million for the quarter ended March 31, 2020. Interest income on nonaccrual loans is recognized only to the extent it is received in cash. However, when there is doubt regarding the ultimate collectability of loan principal, all cash thereafter received is applied to reduce the carrying value of such loans ( i.e., the cost recovery method). Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Generally, the Corporation returns a loan to accrual status when all delinquent interest and principal becomes current under the terms of the loan agreement, or after a sustained period of repayment performance ( 6 months) and the loan is well secured and in the process of collection, and full repayment of the remaining contractual principal and interest is expected. Regarding interest income recognition for PCD loans, the prospective transition approach for PCD assets required by ASC 326 was applied at a pool level, which froze the effective interest rate of the pools as of January 1, 2020. PCD loan pools accounted for as a single unit of accounting are not reported as nonaccrual as long as the Corporation is able to reasonably estimate the timing and amounts of cash flows expected to be collected. Loans that are past due 30 days or more as to principal or interest are considered delinquent, with the exception of residential mortgage, commercial mortgage, and construction loans, which are considered past due when the borrower is in arrears on two or more monthly

POTENTIAL ACQUISITION OF BANCO

POTENTIAL ACQUISITION OF BANCO SANTANDER PUERTO RICO	3 Months Ended

Disclosure Text Block [Abstract]
Unusual or Infrequent Items, or Both, Disclosure [Text Block]	NOTE 2 – POTENTIAL ACQUISITION OF BANCO SANTANDER PUERTO RICO On October 21, 2019, the Corporation announced the signing of a stock purchase agreement between FirstBank and Santander Holdings USA, Inc., pursuant to which FirstBank will acquire Santander Bancorp (“Santander BanCorp”), a wholly-owned subsidiary of Santander Holdings USA, Inc. and the holding company of Banco Santander Puerto Rico (“BSPR”). The purchase price is based on a formula set forth in the stock purchase agreement and is subject to adjustment based on Santander BanCorp's consolidated balance sheet as of the closing date of the acquisition (the “Closing”). The purchase price formula consists of the following: (i) a base purchase price equal to 117.5% of Santander BanCorp's core tangible common equity; (ii) a fixed $ 65 million premium on core tangible common equity; and (iii) an adjustment equal to 100% of the deemed excess capital of Santander BanCorp at Closing. The transaction is structured as an all-cash acquisition of all of the issued and outstanding common stock of Santander Bancorp, the sole shareholder of BSPR, a corporation incorporated under the laws of the Commonwealth of Puerto Rico and sole shareholder of Santander Insurance Agency, Inc. (Santander Bancorp is referred to together with BSPR collectively as the “Acquired Companies”). Immediately following the Closing, Santander Bancorp (a direct wholly-owned subsidiary of FirstBank following the Closing) will merge with and into FirstBank (the “HoldCo Merger”), with FirstBank surviving the HoldCo Merger (the “Surviving Bank”). Immediately following the effectiveness of the HoldCo Merger, BSPR (a direct wholly-owned subsidiary of the Surviving Bank following the effectiveness of the HoldCo Merger) will merge with and into FirstBank, with FirstBank as the surviving entity in the merger. Prior to the Closing, Santander Holdings USA, Inc., has agreed to sell or otherwise transfer to Santander Holdings USA, Inc., any of its affiliates or any other third party (other than any Acquired Company) (i) all non-performing assets (along with all collateral and rights to collection related thereto) of BSPR (the “Non-Performing Assets Transfer”), and (ii) Santander Asset Management, LLC, a limited liability company organized under the laws of the Commonwealth of Puerto Rico and a direct wholly-owned subsidiary of Santander Bancorp (the “Reorganization”). The Closing is conditioned on, among other things, consummation of the Non-Performing Assets Transfer, the Reorganization, and receipt of all required regulatory approvals. Since the third quarter of 2019, the Corporation has incurred in merger and restructuring costs totaling $ 12.2 million in connection with the pending acquisition of BSPR, including $ 0.8 million recorded during the first quarter of 2020, which are presented as Merger and Restructuring costs in the accompanying consolidated statements of income for the first quarter of 2020. Merger and restructuring costs primarily have included advisory, legal, valuation, and other professional service fees, as well as charges related to a voluntary separation program (the “VSP”) offered to eligible employees at FirstBank in connection with initiatives to capitalize on expected operational efficiencies from the acquisition. The transaction has been unanimously approved by both companies’ boards of directors. With respect to the Corporation’s announced transaction to acquire BSPR, the Corporation continues to work with the applicable regulators in their review of the transaction. Taking into account the impact of the COVID-19 pandemic, the Corporation now believes it is unlikely that all regulatory approvals necessary to close the transaction will be received by the middle of 2020 as previously expected. The Corporation continues to cooperate with its regulators and to provide additional requested information as part of the application process. There can be no assurance that the regulatory approvals will not contain a condition or requirement that results in a failure to satisfy the conditions to closing set forth in the stock purchase agreement.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE [Text Block]	NOTE 3 – EARNINGS PER COMMON SHARE The calculation of earnings per common share for the quarters ended March 31, 2020 and 2019 are as follows: Quarter Ended March 31, March 31, 2020 2019 (In thousands, except per share information) Net income $ 2,266 $ 43,314 Less: Preferred stock dividends ( 669) ( 669) Net income attributable to common stockholders $ 1,597 $ 42,645 Weighted-Average Shares: Average common shares outstanding 216,785 216,338 Average potential dilutive common shares 529 612 Average common shares outstanding-assuming dilution 217,314 216,950 Earnings per common share: Basic $ 0.01 $ 0.20 Diluted $ 0.01 $ 0.20 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 the potential dilutive common shares are issued and outstanding and the proceeds from the exercise, in addition to the amount of compensation cost attributable to future services, are used to purchase common stock at the exercise date. The difference between the numbers 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 potential 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

STOCK-BASED COMPENSATION	3 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION [Text Block]	NOTE 4 – 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 compensation incentives (the “awards”) through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, cash-based awards and other stock-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, 2020, 5,745,970 authorized shares of common stock were 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 2020, the Corporation awarded 851,673 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 851,673 shares of restricted stock were 47,194 shares granted to retirement-eligible employees. The total expense determined for the restricted stock awarded to retirement-eligible employees was charged against earnings. During the first quarter 2019, the Corporation awarded to its independent directors 3,745 shares of restricted stock that were subject to one-year 261,871 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 261,871 shares of restricted stock were 13,308 shares granted to retirement-eligible employees. The fair value of the shares of restricted stock granted in the first quarter of 2020 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 2020 under the Omnibus Plan: Quarter Ended March 31, 2020 Number of shares of Weighted-Average restricted Grant Date stock Fair Value Unvested shares outstanding at beginning of period 644,805 $ 8.51 Granted 851,673 4.08 Vested ( 184,370) 6.51 Unvested shares outstanding at March 31, 2020 1,312,108 $ 5.91 For the quarters ended March 31, 2020 and 2019, the Corporation recognized $ 0.8 million and $ 0.9 million, respectively, of stock-based compensation expense related to restricted stock awards. As of March 31, 2020, there was $ 5.2 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, 2020. Stock-based compensation accounting guidance requires the Corporation to reverse compensation expense for any awards that are forfeited due to employee or director turnover. Quarterly changes in the estimated forfeiture rate may have a significant effect on stock-based compensation, as the Corporation recognized 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 result in a decrease in 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 result in an increase in 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 2020, the Corporation granted 502,307 units to executives, with each unit representing the value of one share of the Corporation’s common stock. The performance units granted in 2020 are for the performance period beginning January 1, 2020 and ending on December 31, 2022 and are subject to three-year The performance units will vest based on the achievement of a pre-established tangible book value per share target as of December 31, 2022. All of the performance units will vest if performance is at the pre-established performance target level or above. However, the participants may vest with respect to 50% of the awards to the extent that performance is below the target but at 80% of the pre-established performance target level (the “80% minimum threshold”), which is measured based upon the growth in the tangible book value during the performance cycle. If performance is between the 80% minimum threshold and the pre-established performance target level, the participants will vest on a proportional amount. No performance units will vest if performance is below the 80% minimum threshold. During the first quarter of 2019, the Corporation awarded 200,053 performance units to executives. The performance units granted in 2019 are for the performance period beginning January 1, 2019 and ending on December 31, 2021 and are subject to three-year The fair values of the performance units awarded in the first quarter of 2020 and 2019 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, 2020 and 2019, the Corporation recognized $ 0.3 million and $ 0.1 million, respectively, of stock-based compensation expense related to performance units. As of March 31, 2020, there was $ 4.1 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, 2020, the Corporation withheld 50,285 shares (first quarter of 2019 – 168,679 shares) of the restricted stock 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 treats shares withheld for tax purposes as common stock repurchases.

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 are presented as part of OCI. The following tables show the Corporation’s available-for-sale investments’ fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of March 31, 2020 and December 31, 2019. The tables also include debt securities for which an ACL was recorded as of March 31, 2020 or a credit loss was charged against the amortized cost basis of the debt security prior to the adoption of ASC 326 on January 1, 2020.

These sales have settlement dates in April, thus, as of March 31, 2020, the decrease in the investment securities portfolio was offset by a corresponding increase in accounts receivable on unsettled investment sales included as part of other assets in the consolidated statements of financial condition. Assessment for Credit Losses Debt securities issued by U.S. government agencies, U.S. 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, 2020, and no credit losses are expected, 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. 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, 2020. The Corporation’s credit losses 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 considered the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:  Any adverse change to the credit conditions and liquidity of the issuer, taking into consideration the latest information available about the financial condition of the issuer, credit ratings, the failure of the issuer to make scheduled principal or interest payments, recent legislation and government actions affecting the issuer’s industry; and actions taken by the issuer to deal with the present economic climate;  Changes in the near-term prospects of the underlying collateral for a security, if any, such as changes in default rates, loss severity given default, and significant changes in prepayment assumptions; and  The level of cash flows generated from the underlying collateral, if any, supporting the principal and interest payments of the debt securities. The Corporation’s available-for-sale MBS portfolio includes private label MBS with a fair value of $ 10.3 million, which had unrealized losses of approximately $ 4.7 million at March 31, 2020. 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 State with original FICO scores over 700 and moderate loan-to-value ratios (under 80%), as well as moderate delinquency levels. The Corporation does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before anticipated recovery. The Corporation determine 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 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 and the housing price index. On 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 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, 2020 December 31, 2019 Weighted Range Weighted Range Average Minimum Maximum Average Minimum Maximum Discount rate 12.7% 12.7% 12.7% 13.7% 13.7% 13.7% Prepayment rate 7.9% 6.8% 10.3% 7.9% 6.8% 10.3% Projected Cumulative Loss Rate 8.9% 2.6% 20.7% 2.8% 0.0% 7.4% The Corporation evaluates if a credit loss exists, primarily by monitoring adverse variances in the present value of expected cash flows. During the first quarter of 2020, the Corporation established a $ 0.4 million ACL for these private label MBS, based on a decline in the present value of expected cash flows taking into consideration the effect of the deteriorating forecasted economic conditions due to the COVID-19 pandemic. As of March 31, 2020, the Corporation’s available-for-sale investment securities portfolio also included bonds of the PRHFA with a fair value of $ 7.3 million, which had unrealized net losses of approximately $ 0.8 million. These bonds include a residential pass-through MBS issued by the PRHFA that is collateralized by certain second mortgages with a fair value of $ 3.0 million which had an unrealized loss of $ 1.1 million as of March 31, 2020. 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 payment of 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 second mortgage loans underlying properties. Based on the quarterly analysis performed, management concluded that the impairment on this residential pass-through MBS as of March 31, 2020 was not credit related based primarily on payment performance history and the insurance protection provided by the PRHFA to the underlying collateral. 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 become due and payable. A deterioration of the Puerto Rico economy or fiscal health of the PRHFA could further impact the value of these securities, resulting in losses to the Corporation. The Corporation does not have the intent to sell this security and it is likely that it will not be required to sell the security before its anticipated recovery.

Investments Held to Maturity The amortized cost, gross unrecognized gains and losses, estimated fair value, allowance for credit losses, weighted-average yield and contractual maturities of investment securities held to maturity as of March 31, 2020 and December 31, 2019 were as follows: March 31, 2020 Amortized cost Fair value Gross Unrecognized Allowance for Credit Losses Weighted - average yield % (Dollars in thousands) gains losses Puerto Rico Municipal Bonds: Due within one year $ 321 $ - $ 3 $ 318 $ 99 5.65 After 1 to 5 years 8,122 - 675 7,447 78 4.99 After 5 to 10 years 56,511 - 8,118 48,393 2,999 5.42 After 10 years 73,580 - 18,576 55,004 6,092 5.25 Total investment securities held to maturity $ 138,534 $ - $ 27,372 $ 111,162 $ 9,268 5.31 December 31, 2019 Amortized cost Fair value Gross Unrecognized Weighted - average yield % (Dollars in thousands) gains losses Puerto Rico Municipal Bonds: Due within one year $ 321 $ - $ 6 $ 315 5.84 After 1 to 5 years 8,264 - 736 7,528 5.18 After 5 to 10 years 56,511 - 8,646 47,865 5.77 After 10 years 73,579 - 18,913 54,666 5.44 Total investment securities held to maturity $ 138,675 $ - $ 28,301 $ 110,374 5.56 The following tables show the Corporation’s held-to-maturity investments’ fair value and gross unrecognized losses, aggregated by investment category and length of time that individual securities had been in a continuous unrecognized loss position, as of March 31, 2020 and December 31, 2019, including debt securities for which an ACL was recorded as of March 31, 2020. As of March 31, 2020 Less than 12 months 12 months or more Total Unrecognized Unrecognized Unrecognized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 111,162 $ 27,372 $ 111,162 $ 27,372 As of December 31, 2019 Less than 12 months 12 months or more Total Unrecognized Unrecognized Unrecognized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 110,374 $ 28,301 $ 110,374 $ 28,301 The Corporation determines the ACL of Puerto Rico Municipal Bonds based on the product of a cumulative PD and LGD, and the amortized cost basis of the bonds over their remaining expected life as described in Note 1 – Basis of Presentation and Significant Accounting Policies above. 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, 2020. The Puerto Rico municipal bonds had an allowance for credit losses of $ 9.3 million as of March 31, 2020, of which $ 1.1 million was recorded as a provision for credit losses in the first quarter of 2020. The increase in the ACL during the first quarter of 2020 primarily reflects the effect of the deteriorating economic outlook due to the COVID-19 pandemic on the macroeconomic variables used for the determination of the PD and LGD used in the model. The following table presents the activity in the ACL for debt securities held-to-maturity by major security type for the quarter ended March 31, 2020: Puerto Rico Municipal Bonds (In thousands) Beginning Balance $ - Impact of adopting ASC 326 8,134 Addition for securities for which no previous expected credit losses were recognized (provision for credit losses) 1,134 $ 9,268 During the second quarter of 2019, the oversight board established by PROMESA announced the designation of Puerto Rico’s 78 municipalities as covered instrumentalities under PROMESA. Meanwhile, the latest fiscal plan certified by the PROMESA oversight board did not contemplate a restructuring of the debt of Puerto Rico’s municipalities, but the plan did call for the gradual elimination of budgetary subsidies provided to municipalities by the central government. Furthermore, municipalities are also likely to 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 problems, or measures included in fiscal plans of other government entities, such as the fiscal plans of the Government Development Bank for Puerto Rico (“GDB”) and the Puerto Rico Electric Power Authority (“PREPA”), and, more recently, by the effect of the COVID-19 pandemic on the Puerto Rico and global economy. Given the uncertain effect that the negative 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 may have 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, 2020 and December 31, 2019, the Corporation had no outstanding securities held to maturity that were classified as cash and cash equivalents. Credit Quality Indicators: As mentioned in Note 1 – Basis of Presentation and Significant Accounting Policies above, 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, 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. The assets categories are defined below: Pass – Assets classified as pass have a well-defined primary source of repayment, with no apparent risk, strong financial position, minimal operating risk, profitability, liquidity and strong capitalization. Special Mention – A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Corporation’s credit position at some future date. Special Mention assets are not adversely classified and do not expose the Corporation to sufficient risk to warrant adverse classification. Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Doubtful classifications have all of the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable, on the basis of currently known facts, conditions and values. A Doubtful classification may be appropriate in cases where significant risk exposures are perceived, but loss cannot be determined because of specific reasonable pending factors, which may strengthen the credit in the near term. Loss – Assets classified Loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this asset even though partial recovery may occur in the future. There is little or no prospect for near term improvement and no realistic strengthening action of significance pending. The Corporation periodically reviews its asset classifications 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, which 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. This group evaluates the credit risk profile of portfolios, including the assessment of the risk rating representative of the current credit quality of the assets, and the evaluation of collateral documentation, if applicable. 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 of the Corporation’s Board of Directors. The following table summarizes the amortized cost of debt securities held-to-maturity as of March 31, 2020 and December 31, 2019 aggregated by credit quality indicator: Held to Maturity Puerto Rico Municipal Bonds March 31, December 31 (In thousands) 2020 2019 Risk Ratings: Pass $ 138,534 $ 138,675 Criticized: Special Mention - - Substandard - - Doubtful - - Loss - - Total $ 138,534 $ 138,675 No held-to-maturity debt securities were on nonaccrual status, 90 days past due and still accruing, or past due as of March 31, 2020 and December 31, 2019. A security is considered to be past due once it is 30 days contractually past due under the terms of the agreement.

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.

Credit card loans continue to accrue finance charges and fees until charged-off at 180 days. It is the Corporation's policy to report delinquent residential mortgage loans insured by the FHA, guaranteed by the VA, and other government-insured loans as past-due loans 90 days and still accruing as opposed to nonaccrual loans since the principal repayment is insured. The Corporation continues accruing interest on these loans until they have passed the 15 months delinquency mark, taking into consideration the FHA interest curtailment process. These balances include $ 37.9 million of residential mortgage loans insured by the FHA that were over 15 months delinquent. As of December 31, 2019, includes $ 35.6 million of defaulted loans collateralizing GNMA securities for which the Corporation has an unconditional option (but not an obligation) to repurchase the defaulted loans. 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, other residential mortgage loans, commercial mortgage loans, and construction loans past due 30-59 days as of December 31, 2019 amounted to $ 7.1 million, $ 116.2 million, $ 6.6 million, and $ 0.1 million respectively. Amount includes PCD residential mortgage loans with individual delinquencies as follow: current – $ 101.2 million, 60-89 days past due –$ 7.5 million, and 90 days or more past due – $ 25.0 million. Amount includes PCD commercial mortgage loans with individual delinquencies as follow: current –$ 0.9 million, and 90 days or more past due – $ 2.0 million. Credit Quality Indicators: The Corporation categorized loans into risk categories based on relevant information about the ability of the borrower 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 loan classifications 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 above. For residential mortgage and consumer loans, the Corporation also evaluates credit quality based on credit scores and loan-to-value ratios, if applicable. 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 13, 2020 and the amortized cost of commercial and construction loans by portfolio classes based on the internal credit-risk category as of December 31, 2019 was as follows: As of March 31, 2020 Puerto Rico and Virgin Islands Region Term Loans As of December 31, 2019 Amortized Cost Basis by Origination Year (In thousands) 2020 2019 2018 2017 2016 Prior Revolving Loans Amortized Cost Basis Total Total CONSTRUCTION Risk Ratings: Pass $ 5,033 $ 13,945 $ 3,170 $ 14,629 $ 5,329 $ 3,992 $ - $ 46,098 $ 35,680 Criticized: Special Mention - - - - - - - - - Substandard - 886 1,858 - 5,150 4,521 - 12,415 12,566 Doubtful - - - - - - - - - Loss - - - - - - - - - Total construction loans $ 5,033 $ 14,831 $ 5,028 $ 14,629 $ 10,479 $ 8,513 $ - $ 58,513 $ 48,246 COMMERCIAL MORTGAGE Risk Ratings: Pass $ 86,063 $ 295,273 $ 175,341 $ 42,555 $ 73,336 $ 260,877 $ 13 $ 933,458 $ 891,298 Criticized: Special Mention 284 - - 79,998 - 11,205 - 91,487 13,080 Substandard - - - - 2,337 52,107 - 54,444 175,522 Doubtful - - - - - - - - - Loss - - - - - - - - - Total commercial mortgage loans $ 86,347 $ 295,273 $ 175,341 $ 122,553 $ 75,673 $ 324,189 $ 13 $ 1,079,389 $ 1,079,900 COMMERCIAL AND INDUSTRIAL Risk Ratings: Pass $ 10,811 $ 225,388 $ 146,464 $ 138,815 $ 55,130 $ 304,636 $ 423,165 $ 1,304,409 $ 1,321,804 Criticized: Special Mention - - 573 933 82 9,175 8,485 19,248 39,327 Substandard - 96 2,491 98 1,197 38,136 5,753 47,771 27,265 Doubtful - - - - - - - - 2,768 Loss - - - - - - - - 249 Total commercial and industrial loans $ 10,811 $ 225,484 $ 149,528 $ 139,846 $ 56,409 $ 351,947 $ 437,403 $ 1,371,428 $ 1,391,413 As of March 31, 2020 Term Loans As of December 31, 2019 Florida Region Amortized Cost Basis by Origination Year (In thousands) 2020 2019 2018 2017 2016 Prior Revolving Loans Amortized Cost Basis Total Total CONSTRUCTION Risk Ratings: Pass $ 30,335 $ 9,744 $ 39,703 $ 17,064 $ - $ - $ 4,316 $ 101,162 $ 63,071 Criticized: Special Mention - - - - - - - - - Substandard - - - - - - - - - Doubtful - - - - - - - - - Loss - - - - - - - - - Total construction loans $ 30,335 $ 9,744 $ 39,703 $ 17,064 $ - $ - $ 4,316 $ 101,162 $ 63,071 COMMERCIAL MORTGAGE Risk Ratings: Pass $ 1,314 $ 82,887 $ 36,929 $ 46,347 $ 52,333 $ 90,578 $ 64,661 $ 375,049 $ 364,370 Criticized: Special Mention - - - - - - - - - Substandard - - - - - 315 - 315 316 Doubtful - - - - - - - - - Loss - - - - - - - - - Total commercial mortgage loans $ 1,314 $ 82,887 $ 36,929 $ 46,347 $ 52,333 $ 90,893 $ 64,661 $ 375,364 $ 364,686 COMMERCIAL AND INDUSTRIAL Risk Ratings: Pass $ 34,894 $ 244,020 $ 152,326 $ 164,636 $ 21,747 $ 65,450 $ 179,979 $ 863,052 $ 837,697 Criticized: Special Mention - - - - - - - - 1,766 Substandard - - - - - 1,738 - 1,738 - Doubtful - - - - - - - - - Loss - - - - - - - - - Total commercial and industrial loans $ 34,894 $ 244,020 $ 152,326 $ 164,636 $ 21,747 $ 67,188 $ 179,979 $ 864,790 $ 839,463 As of March 31, 2020 Total Term Loans As of December 31, 2019 Amortized Cost Basis by Origination Year (In thousands) 2020 2019 2018 2017 2016 Prior Revolving Loans Amortized Cost Basis Total Total CONSTRUCTION Risk Ratings: Pass $ 35,368 $ 23,689 $ 42,873 $ 31,693 $ 5,329 $ 3,992 $ 4,316 $ 147,260 $ 98,751 Criticized: Special Mention - - - - - - - - - Substandard - 886 1,858 - 5,150 4,521 - 12,415 12,566 Doubtful - - - - - - - - - Loss - - - - - - - - - Total construction loans $ 35,368 $ 24,575 $ 44,731 $ 31,693 $ 10,479 $ 8,513 $ 4,316 $ 159,675 $ 111,317 COMMERCIAL MORTGAGE Risk Ratings: Pass $ 87,377 $ 378,159 $ 212,270 $ 88,902 $ 125,669 $ 351,455 $ 64,674 $ 1,308,506 $ 1,255,668 Criticized: Special Mention 284 - - 79,999 - 11,205 - 91,488 13,080 Substandard - - - - 2,337 52,422 - 54,759 175,838 Doubtful - - - - - - - - - Loss - - - - - - - - - Total commercial mortgage loans $ 87,661 $ 378,159 $ 212,270 $ 168,901 $ 128,006 $ 415,082 $ 64,674 $ 1,454,753 $ 1,444,586 COMMERCIAL AND INDUSTRIAL Risk Ratings: Pass $ 45,706 $ 469,408 $ 298,790 $ 303,451 $ 76,877 $ 370,085 $ 603,144 $ 2,167,461 $ 2,159,501 Criticized: Special Mention - - 573 933 82 9,175 8,485 19,248 39,327 Substandard - 96 2,491 98 1,197 39,874 5,753 49,509 29,031 Doubtful - - - - - - - - 2,768 Loss - - - - - - - - 249 Total commercial and industrial loans $ 45,706 $ 469,504 $ 301,854 $ 304,482 $ 78,156 $ 419,134 $ 617,382 $ 2,236,218 $ 2,230,876 The following table presents the amortized cost in residential mortgage loans by origination year based on original loan-to-value-ratio (LTV) and original credit scores as of March 31, 2020 and the amortized cost in residential mortgage loans by original LTV and original credit scores as of December 31, 2019: As of March 31, 2020 As of December 31, 2019 Term Loans RESIDENTIAL MORTGAGES Amortized Cost Basis by Origination Year (In thousa

The ACL for loans and finance leases was $ 155.1 million as of December 31, 2019. Upon adoption of CECL on January 1, 2020, the Corporation recognized an increase in the ACL for loans and finance leases of approximately $ 81.2 million, as a cumulative effect adjustment from the adoption of ASC 326, with a corresponding decrease in retained earnings, net of applicable income taxes. As of March 31, 2020, the ACL for loans and finance leases was $ 292.8 million, up $ 137.7 million from December 31, 2019, driven by the $ 81.2 million increase as a result of adopting CECL and a $ 56.5 million reserve build ( i.e. , provision of $ 74.0 million in excess of net charge-offs of $ 17.6 million) in the first quarter of 2020. The increase in the ACL across all loan portfolio categories primarily reflects the effect of a deteriorating economic outlook due to the COVID-19 pandemic on the macroeconomic variables used for the determination of the PDs and LGDs used in the different models. For those loans where the ACL was determined based on a discounted cash flow model, as indicated in Note 1 – Basis of Presentation and Significant Accounting Policies above, the change in the ACL due to the passage of time is recorded as part of the provision for credit losses. The tables below present the allowance for credit losses on loans and finance leases and the carrying value of loans by portfolio segment as of March 31, 2020 and December 31, 2019: As of March 31, 2020 Residential Mortgage Loans Commercial Mortgage Loans Commercial and Industrial Loans Consumer Loans Construction Loans (Dollars in thousands) Total Total loans held for investment: Amortized cost of loans $ 2,875,672 $ 159,675 $ 1,454,753 $ 2,236,218 $ 2,312,629 $ 9,038,947 Allowance for credit losses 107,082 5,253 33,971 38,310 108,158 292,774 Allowance for credit losses to amortized cost 3.72 % 3.29 % 2.34 % 1.71 % 4.68 % 3.24 % As of December 31, 2019 Residential Mortgage Loans Commercial Mortgage Loans Commercial and Industrial Loans Consumer Loans Construction Loans (Dollars in thousands) Total Total loans held for investment: Amortized cost of loans $ 2,933,773 $ 111,317 $ 1,444,586 $ 2,230,876 $ 2,281,653 $ 9,002,205 Allowance for credit losses 44,806 2,370 39,194 15,198 53,571 155,139 Allowance for credit losses to amortized cost 1.53 % 2.13 2.71 % 0.68 % 2.35 % 1.72 % 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 – Basis of Presentation and Significant Accounting Policies above. Upon adoption of CECL on January 1, 2020, the Corporation recognized an increase in the ACL for off-balance sheet exposures of approximately $ 3.9 million, as a cumulative effect adjustment from the adoption of ASC 326, with a corresponding decrease in retained earnings, net of applicable income taxes. As of March 31, 2020, the ACL for off-balance sheet credit exposures was $ 5.7 million, including the $ 3.9 million effect of adopting CECL and a $ 1.8 million charge to the provision in the first quarter of 2020. The increase in the allowance for credit losses for unfunded loan commitments in the first quarter of 2020 primarily reflects the effect of the deteriorating economic outlook due to the COVID-19 pandemic. The following table presents the activity in the ACL for unfunded loan commitments and standby letters of credit for the quarters ended March 31, 2020 and 2019: Quarter ended March 31, 2020 March 31, 2019 (In thousands) Beginning Balance $ - $ 412 Impact of adopting ASC 326 3,922 - Provision (release) for credit losses 1,819 ( 412) Ending balance $ 5,741 $ -

DERIVATIVE INSTRUMENTS AND HEDG

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES [Text Block]	NOTE 12 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES One of the market risks facing the Corporation is interest rate risk, which includes the risk that changes in interest rates will result in changes in the value of the Corporation’s assets or liabilities and will adversely affect the Corporation’s net interest income from its loan and investment portfolios. The overall objective of the Corporation’s interest rate risk management activities is to reduce the variability of earnings caused by changes in interest rates. The Corporation designates a derivative as a fair value hedge, cash flow hedge or economic undesignated hedge when it enters into the derivative contract. As of March 31, 2020 and December 31, 2019, all derivatives held by the Corporation were considered economic undesignated hedges. The Corporation records these undesignated hedges at fair value with the resulting gain or loss recognized in current earnings. The following summarizes the principal derivative activities used by the Corporation in managing interest rate risk: Interest rate cap agreements - Interest rate cap agreements provide the right to receive cash if a reference interest rate rises above a contractual rate. The value of the interest rate cap increases as the reference interest rate rises. The Corporation enters into interest rate cap agreements for protection from rising interest rates. Forward Contracts - Forward contracts are primarily sales of to-be-announced (“TBA”) MBS that will settle over the standard delivery date and do not qualify as “regular way” security trades. Regular-way security trades are contracts that have no net settlement provision and no market mechanism to facilitate net settlement and that provide for delivery of a security within the time frame generally established by regulations or conventions in the market place or exchange in which the transaction is being executed. The forward sales are considered derivative instruments that need to be marked to market. The Corporation uses these securities to economically hedge the FHA/VA residential mortgage loan securitizations of the mortgage-banking operations. The Corporation also reports as forward contracts the mandatory mortgage loan sales commitments that it enters into with GSEs that require or permit net settlement via a pair-off transaction or the payment of a pair-off fee. Unrealized gains (losses) are recognized as part of Mortgage banking activities in the consolidated statements of income. Interest Rate Lock Commitments - Interest rate lock commitments are agreements under which the Corporation agrees to extend credit to a borrower under certain specified terms and conditions in which the interest rate and the maximum amount of the loan are set prior to funding. Under the agreement, the Corporation commits to lend funds to a potential borrower, generally on a fixed rate basis, regardless of whether interest rates change in the market. To satisfy the needs of its customers, the Corporation may enter into non-hedging transactions. In these transactions, the Corporation generally participates as a buyer in one of the agreements and as a seller in the other agreement under the same terms and conditions. In addition, the Corporation enters into certain contracts with embedded derivatives that do not require separate accounting as these are clearly and closely related to the economic characteristics of the host contract. When the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract, it is bifurcated, carried at fair value, and designated as a trading or non-hedging derivative instrument.

As is the case with investment securities, the market value of derivative instruments is largely a function of the financial market’s expectations regarding the future direction of interest rates. Accordingly, current market values are not necessarily indicative of the future impact of derivative instruments on earnings. This will depend, for the most part, on the shape of the yield curve, and the level of interest rates, as well as the expectations for rates in the future. As of March 31, 2020, the Corporation had not entered into any derivative instrument containing credit-risk-related contingent features.

Goodwill And Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES [Text Block]	NOTE 14 – GOODWILL AND OTHER INTANGIBLES Goodwill as of both March 31, 2020 and December 31, 2019 amounted to $ 28.1 million, recognized as part of Other Assets in the consolidated statements of financial condition. The Corporation’s goodwill is related to the Florida reporting unit. The Corporation conducted its annual evaluation of goodwill and other intangibles during the fourth quarter of 2019. Such analysis indicated that it is more likely than not that the reporting unit’s fair value is greater than its carrying value based on a qualitative assessment of events and circumstances that could impact the latest quantitative estimate of fair value of the reporting unit performed in the fourth quarter of 2018. During the first quarter of 2020, the COVID-19 pandemic broadly impacted the operating environment, notably in March, causing a sharp contraction in global economic activity and increased market volatility affecting both equity and credit markets. Due to this event, the Corporation performed a qualitative assessment to conclude if recent events constituted a triggering event that would indicate that it is more likely than not that the reporting unit is impaired. Although the market volatility resulting from uncertainties around the COVID-19 pandemic negatively broadly affected macroeconomic and equity market indicators, the duration and extent of the effects of the COVID-19 pandemic are highly uncertain at this time and its ultimate effect could be affected by measures implemented by central banks and governments aimed at mitigating the contraction in economic activity and market concerns. There were no other events, specific to the reporting unit, that would have had a significant negative impact on the valuation of the reporting unit. Ultimately, the Corporation concluded that the COVID-19 event not to be a triggering event to perform a quantitative test or to accelerate the indefinite life intangibles impairment analyses. As a result, no impartment charges for goodwill and indefinite-lived intangible assets were recorded during the first quarter of 2020. In connection with the acquisition of the FirstBank-branded credit card loan portfolio in the second quarter of 2012, the Corporation recognized a purchased credit card relationship intangible of $ 24.5 million ($ 3.1 million as of March 31, 2020 and $ 3.6 million as of December 31, 2019), which is being amortized over the remaining estimated life of 1.6 years on an accelerated basis based on the estimated attrition rate of the purchased credit card accounts, which reflects the Corporation’s estimate that it will realize the economic benefits of the intangible asset as the revenue stream generated by the cardholder relationship is realized. The core deposit intangible of $ 3.3 million as of March 31, 2020 (December 31, 2019 - $ 3.5 million) primarily consisted of the core deposit acquired in the February 2015 Doral Bank transaction described in Note 1 – Basis of Presentation and Significant Accounting Policies above. In the first quarter of 2016, FirstBank Insurance Agency acquired insurance customer accounts and related customer records and recognized an insurance customer relationship intangible of $ 1.1 million ($ 0.4 million as of March 31, 2020 and $ 0.5 million as of December 31, 2019). The acquired accounts have a direct relationship to the previous mortgage loan portfolio acquisitions from Doral Bank and Doral Financial in 2015 and 2014. The following table shows the gross amount and accumulated amortization of the Corporation’s intangible assets recognized as part of Other assets in the consolidated statements of financial condition as of indicated dates: As of As of March 31, December 31, 2020 2019 (Dollars in thousands) Core deposit intangible: Gross amount $ 51,664 $ 51,664 Accumulated amortization (1) ( 48,377) ( 48,176) Net carrying amount $ 3,287 $ 3,488 Remaining amortization period (in years) 4.8 5.1 Purchased credit card relationship intangible: Gross amount $ 24,465 $ 24,465 Accumulated amortization (2) ( 21,324) ( 20,850) Net carrying amount $ 3,141 $ 3,615 Remaining amortization period (in years) 1.6 1.9 Insurance customer relationship intangible: Gross amount $ 1,067 $ 1,067 Accumulated amortization (3) ( 635) ( 597) Net carrying amount $ 432 $ 470 Remaining amortization period (in years) 2.8 3.0 For each of the quarters ended March 31, 2020 and 2019, the amortization expense of core deposit intangibles amounted to $ 0.2 million.

For each of the quarters ended March 31, 2020 and 2019, the amortization expense of the insurance customer relationship intangible amounted to $ 38 The estimated aggregate annual amortization expense related to the intangible assets for future periods is as follows as of March 31, 2020: Amount (In thousands) 2020 $ 2,138 2021 2,656 2022 915 2023 622 2024 457 2025 and after 72

NON-CONSOLIDATED VARIABLE INTER

NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	3 Months Ended

Transfers and Servicing [Abstract]
NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS [Text Block]	NOTE 15 – 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: GNMA 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, 2020, the Corporation serviced loans securitized through GNMA with a principal balance of $ 1.9 billion. 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 are presented in the Corporation’s consolidated statements of financial condition as other borrowings, net of related issuance costs. 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). 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, 2020, 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 Corporation’s banking subsidiary. 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 90-day 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 securities. 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, 2020, the amortized cost and fair value of these private label MBS amounted to $ 15.4 million and $ 10.3 million, respectively, with a weighted-average yield of 3.45%, which is included as part of the Corporation’s available-for-sale investment securities portfolio. As described in Note 5 – Investment Securities above, the Corporation established a $ 0.4 million ACL on these private label MBS during 2020. 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 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 has used cash proceeds on the loan to cover operating expenses and debt service payments, including those related to the refinanced 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 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 The Corporation sells residential mortgage loans to GNMA, which generally securitizes the transferred loans into MBS. 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. Servicing assets are included as part of Other assets in the consolidated statements of financial condition. The changes in servicing assets are shown below for the indicated periods: Quarter ended March 31, March 31, 2020 2019 (In thousands) Balance at beginning of period $ 26,762 $ 27,428 Capitalization of servicing assets 904 868 Amortization ( 1,009) ( 810) Temporary impairment charges, net ( 138) ( 20) Other (1) ( 35) ( 35) Balance at end of period $ 26,484 $ 27,431 (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, 2020 2019 (In thousands) Balance at beginning of period $ 73 $ 30 Temporary impairment charges 138 24 OTTI of servicing assets ( 77) - Recoveries - ( 4) Balance at end of period $ 134 $ 50 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, 2020 2019 (In thousands) Servicing fees $ 2,134 $ 2,060 Late charges and prepayment penalties 150 154 Adjustment for loans repurchased ( 35) ( 35) Other - ( 15) Servicing income, gross 2,249 2,164 Amortization and impairment of servicing assets ( 1,147) ( 830) Servicing income, net $ 1,102 $ 1,334 The Corporation’s servicing assets are subject to prepayment and interest rate risks. As of March 31, 2020, fair values of the Corporation’s servicing assets were based on a valuation model that incorporates market-driven assumptions regarding discount rates and mortgage prepayment rates, adjusted by the particular characteristics of the Corporation’s servicing portfolio. The Corporation used constant prepayment rate assumptions for the Corporation’s servicing assets for the government-guaranteed mortgage loans of 6.2% for each of the quarters ended March 31, 2020 and 2019. For conventional conforming mortgage loans, the Corporation used 6.9% and 6.7% for the quarters ended March 31, 2020 and 2019, and, for the conventional non-conforming mortgage loans, the Corporation used 8.7% and 9.3% for the quarters ended March 31, 2020 and 2019, respectively. Discount rate assumptions used were % for government-guaranteed mortgage loans; % for conventional conforming mortgage loans; and % for conventional non-conforming mortgage loans for each of the quarters ended March 31, 2020 and 2019. 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, 2020 and December 31, 2019 were as follows: March 31, December 31, 2020 2019 (In thousands) Carrying amount of servicing assets $ 26,484 $ 26,762 Fair value $ 30,337 $ 31,027 Weighted-average expected life (in years) 8.39 8.39 Constant prepayment rate (weighted-average annual rate) 6.46% 6.45% Decrease in fair value due to 10% adverse change $ 764 $ 748 Decrease in fair value due to 20% adverse change $ 1,496 $ 1,464 Discount rate (weighted-average annual rate) 11.27% 11.27% Decrease in fair value due to 10% adverse change $ 1,393 $ 1,450 Decrease in fair value due to 20% adverse change $ 2,677 $ 2,783 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 servicing asset 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.

Short-term Debt [Text Block]	NOTE 17 – LOANS PAYABLE As of March 31, 2020, loans payable consisted of $ 60 million in short-term borrowings under the Primary Credit FED Discount Window Program bearing interest at 0.25%. The Corporation participates in the Borrower-in-Custody (“BIC”) Program of the FED. Through the BIC Program, a broad range of loans (including commercial, consumer and residential mortgages) may be pledged as collateral for borrowings through the FED Discount Window. As of March 31, 2020, collateral pledged related to this credit facility amounted to $ 1.2 billion, mainly commercial, consumer and residential mortgage loans, which after a margin haircuts resulted in over $ 758 million in lendable value. With the COVID-19 impacts on individual, communities and organizations continuing to evolve, the Federal Reserve has taken several actions to support the economy and financial stability including, among other things, lowering the target range for the federal funds rate and relaunching large scale asset purchases. The FED discount Window program provided the opportunity to access a low-rate short-term source of funding in the current high volatility market environment.

As of March 31, 2020 and December 31, 2019, there were 222,955,394 and 222,103,721 shares issued, respectively, and 218,160,725 and 217,359,337 shares outstanding, respectively. Refer to Note 4 – Stock-Based Compensation, to the consolidated financial statements, for information about transactions related to common stock under the Omnibus Plan. On February 6, 2020, the Corporation announced that its Board of Directors declared a quarterly cash dividend of $ 0.05 per common share that was paid on March 13, 2020 to shareholders of record at the close business on February 28, 2020. For the quarters ended March 31, 2020 and 2019, total cash dividends declared on shares of common stock amounted to $ 10.9 million and $ 6.5 million, respectively. The Corporation intends to continue to pay quarterly dividends on common stock. 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. As of March 31, 2020, the Corporation has five outstanding series of non-convertible, non-cumulative preferred stock: 7.125% non-cumulative perpetual monthly income preferred stock, Series A; 8.35% non-cumulative perpetual monthly income preferred stock, Series B; 7.40% non-cumulative perpetual monthly income preferred stock, Series C; 7.25% non-cumulative perpetual monthly income preferred stock, Series D; and 7.00% non-cumulative perpetual monthly income preferred stock, Series E. The liquidation value per share is $ 25. Effective January 17, 2012, the Corporation delisted all of its outstanding series of non-convertible, non-cumulative preferred stock from the New York Stock Exchange. The Corporation has not arranged for listing and/or registration on another national securities exchange or for quotation of the Series A through E preferred stock in a quotation medium. The Corporation has continued to pay monthly dividend payments on the non-cumulative perpetual monthly income preferred stock. For each of the quarters ended March 31, 2020 and 2019, total cash dividends declared on shares of preferred stock amounted to $ 0.7 million. The Corporation intends to continue to make monthly dividend payments on the non-cumulative perpetual to make monthly income preferred stock. Treasury stock During the first quarter of 2020 and 2019, the Corporation withheld an aggregate of 50,285 shares and 168,679 shares, respectively, of the restricted stock that vested during those quarters, to cover the officers’ payroll and income tax withholding liabilities; these shares are held as treasury stock. As of March 31, 2020 and December 31, 2019, the Corporation had 4,794,669 and 4,744,384 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 there is no legal surplus reserve 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 $ 97.6 million as of March 31, 2020 and December 31, 2019. There were no transfers to the legal surplus reserve during the quarter ended March 31, 2020.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES [Text Block]	NOTE 22 - 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 (“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 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. The Coronavirus Aid, Relief, and Economic Security (CARES) Act, which the U.S. Congress enacted on March 27, 2020, includes several provisions to stimulate the U.S. economy in the midst of the COVID-19 pandemic. The CARES Act includes tax provisions that temporarily modified the taxable income limitations for NOL usage to offset future taxable income, NOL carryback provisions and other related income and non-income based tax laws. The Corporation has evaluated such provisions and determined that the impact of the CARES Act on the income tax provision and deferred tax assets as of March 31, 2020 was not significant. For the first quarter of 2020, the Corporation recorded an income tax benefit of $ 3.0 17.6 million for the same period in 2019. The variance was mostly attributable to an income tax benefit of approximately $ 20.0 For the quarter ended March 31, 2020, 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 2020, excluding entities from which a tax benefit cannot be recognized and discrete items, was 24% compared to 28% for the first quarter of 2019. The estimated annual effective tax rate including all entities for 2020 was 26% ( 25% excluding discrete items), compared to 29% for the first quarter of 2019 ( 26% excluding discrete items). On January 1, 2020, the Corporation increased its deferred tax assets by $ 31.3 million in connection with the transitional adjustment resulting from the adoption of the CECL accounting standard. The Corporation’s net deferred tax asset amounted to $ 307.8 million as of March 31, 2020, net of a valuation allowance of $ 88.5 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. Due to the inherent uncertainties related to the extent and duration of the COVID-19 pandemic, there is no evidence that can be objectively verified at this time to affect the Corporation’s assessment about the ability to realize its deferred tax assets. The net deferred tax asset of the Corporation’s banking subsidiary, FirstBank, amounted to $ 307.7 million as of March 31, 2020, net of a valuation allowance of $ 52.7 million, compared to a net deferred tax asset of $ 264.8 million, net of a valuation allowance of $ 55.6 million, as of December 31, 2019. 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 2020, the Corporation incurred an income tax expense of approximately $ 1 million related to its U.S. operations, compared to $ 1.8 million for the same period in 2019. The limitation did not impact the USVI operations in the first quarter of 2020 and 2019. As of March 31, 2020, the Corporation did not have UTBs recorded on its books. The Corporation classifies all interest and penalties, if any, related to tax uncertainties as income tax expense. Audit periods remain open for review until the statute of limitations has passed. 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 2015 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2015 remain open to examination.

FAIR VALUE

FAIR VALUE	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE [Text Block]	NOTE 24 – 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 judgments 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, when available, 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 (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 certain 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 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, 2020 and 2019 was immaterial. Assets and liabilities measured at fair value on a recurring basis are summarized below as of March 31, 2020 and December 31, 2019: As of March 31, 2020 As of December 31, 2019 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 $ 7,582 $ - $ - $ 7,582 $ 7,479 $ - $ - $ 7,479 Noncallable U.S. agency debt securities - 146,154 - 146,154 - 146,777 - 146,777 Callable U.S. agencies debt securities and MBS - 1,760,312 - 1,760,312 - 1,950,331 - 1,950,331 Puerto Rico government obligations - 4,361 2,969 7,330 - 4,348 2,974 7,322 Private label MBS - - 10,300 10,300 - - 11,116 11,116 Other investments - - 500 500 - - 500 500 Equity securities 1,458 - - 1,458 1,428 - - 1,428 Derivatives, included in assets: Purchased interest rate cap agreements - 9 - 9 - 11 - 11 Interest rate lock commitments - 303 - 303 - 341 - 341 Forward loan sales commitments - 20 - 20 - 20 - 20 Liabilities: Derivatives, included in liabilities: Written interest rate cap agreements - 9 - 9 - 11 - 11 Forward contracts - 803 - 803 - 138 - 138 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, 2020 and 2019: Quarter ended March 31, 2020 2019 Level 3 Instruments Only Securities Securities (In thousands) Available For Sale (1) Available For Sale (1) Beginning balance $ 14,590 17,238 Total (losses) gains (realized/unrealized): Included in other comprehensive income 240 ( 23) Included in earnings ( 368) - Principal repayments and amortization ( 693) ( 509) Ending balance $ 13,769 $ 16,706 Amounts mostly related to private label MBS.

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 prepayment 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 higher (lower) fair value estimate. The fair value of these bonds was based on a discounted cash flow analysis that contemplates the credit quality of the holder of second mortgages and a discount for liquidity constraints on the bonds considering the absence of an active market for them. Due to the guarantee of the PRHFA and other applicable contractual safeguards, the Corporation does not apply any additional credit spread for debt service default. The table below summarizes changes in unrealized gains and losses recorded in earnings for the quarters ended March 31, 2020 and 2019 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) 2020 2019 Changes in unrealized losses relating to assets still held at reporting date: Provision for credit losses $ ( 368) $ - 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, 2020, 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, 2020 Losses recorded for the Quarter Ended March 31, 2020 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 291,856 $ ( 6,393) OREO (2) - - 99,674 ( 654) Consists mainly of collateral dependent commercial and construction loans.

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 Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMER [Text Block]	NOTE 25 – REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition In accordance with ASC Topic 606, “Revenues from Contracts with Customers,” 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 segments for the quarters ended March 31, 2020 and 2019: (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended March 31, 2020: Net interest income (1) $ 17,058 $ 57,744 $ 23,581 $ 19,875 $ 13,785 $ 6,606 $ 138,649 Service charges and fees on deposit accounts - 3,483 1,564 - 168 742 5,957 Insurance commissions - 4,376 - - 4 202 4,582 Merchant-related income - 750 - - - 149 899 Credit and debit card fees - 4,217 17 - 10 422 4,666 Other service charges and fees 74 617 412 - 418 147 1,668 Not in scope of Topic 606 (1) 3,566 285 18 8,328 231 - 12,428 Total non-interest income 3,640 13,728 2,011 8,328 831 1,662 30,200 Total Revenue $ 20,698 $ 71,472 $ 25,592 $ 28,203 $ 14,616 $ 8,268 $ 168,849 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended March 31, 2019: Net interest income (1) $ 17,749 $ 61,534 $ 20,933 $ 16,795 $ 16,209 $ 6,961 $ 140,181 Service charges and fees on deposit accounts - 3,524 1,324 - 136 732 5,716 Insurance commissions - 4,066 - - 11 173 4,250 Merchant-related income - 834 196 - - 264 1,294 Credit and debit card fees - 4,398 320 - 169 516 5,403 Other service charges and fees 44 843 426 - 133 82 1,528 Not in scope of Topic 606 (1) 3,562 342 252 74 84 38 4,352 Total non-interest income 3,606 14,007 2,518 74 533 1,805 22,543 Total Revenue $ 21,355 $ 75,541 $ 23,451 $ 16,869 $ 16,742 $ 8,766 $ 162,724 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, 2020 and 2019, 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, non-sufficient 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, nonsubstantive 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, 2020 and 2019, respectively, the Corporation recognized revenue of $ 3.1 million and $ 2.7 million, respectively, at the time that payments were confirmed and constraints were released. 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 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, and bank issuances of checks. The Corporation recognizes such fees concurrently with the event or on a monthly basis. 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 contract requires the Bank to either launch a new debit card product by March 30, 2021 or maintain a ratio of over 50% of the portfolio with the related card service association by the end of year 2021. In connection with this agreement, the Corporation recognized a contract liability as the revenue is constrained to the fulfillment of either of the above conditions. 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 FirstBank’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, 2020 and March 31, 2019, this contract liability amounted to $ 2.4 million and $ 2.0 million, respectively, which will be recognized over the remaining term of the contract. For each of the quarters ended March 31, 2020 and 2019, the Corporation recognized revenue and its contract liabilities decreased by approximately $ 0.1 million, 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, 2020 and March 31, 2019, 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, 2020 and 2019: (In thousands) March 31, 2020 March 31, 2019 Beginning Balance $ 2,476 $ 2,071 Less: Amortizations ( 81) ( 81) Ending balance $ 2,395 $ 1,990 Other Except for the contract liabilities noted above, the Corporation did not have any significant performance obligations as of March 31, 2020. 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 27 – 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, 2020, 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 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 retail banking services. The Virgin Islands Operations segment consists of all banking activities conducted by the Corporation in the USVI and BVI, including commercial and retail 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 of the Corporation for the year ended December 31, 2019, which are included in the 2019 Annual Report on Form 10-K and updates to significant accounting policies described in Note 1 – Basis of Presentation and Significant Accounting Policies of this Form 10-Q. 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.

Commitments And Contingencies Disclosure [Abstract]
REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES [Text Block]	NOTE 28 – REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES The Corporation and FirstBank are each subject to various regulatory capital requirements imposed by the 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, 2020 and December 31, 2019, 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, 2020, management does not believe that any condition has changed or event has occurred that would have changed the institution’s status. Although the Corporation and FirstBank became subject to the U.S. Basel III capital rules (“Basel III rules”) beginning on January 1, 2015, certain elements of the Basel III have been deferred by the federal banking agencies. The Corporation and FirstBank compute risk-weighted assets using the Standardized Approach required by the Basel III rules. The Basel III rules require the Corporation to maintain an additional capital conservation buffer of 2.5% 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. Under the Basel III rules, in order to be considered adequately capitalized and not subject to the above described limitations, the Corporation is required to maintain: (i) a minimum Common Equity Tier 1 Capital (“CET1”) capital to risk-weighted assets ratio of at least 4.5%, plus the 2.5% “capital conservation buffer,” resulting in a required minimum CET1 ratio of at least 7%; (ii) a minimum ratio of total Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum Tier 1 capital ratio of 8.5%; (iii) a minimum ratio of total Tier 1 plus Tier 2 capital to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum total capital ratio of 10.5%; and (iv) a required minimum leverage ratio of 4%, calculated as the ratio of Tier 1 capital to average on-balance sheet (non-risk adjusted) assets. The Federal Reserve Board, the FDIC, and the Office of the Comptroller of the Currency (collectively “the agencies”) have issued several rulemakings over the last two years to simplify certain aspects of the capital rule. For example, the capital rule included transitional arrangements for mortgage servicing assets, temporary difference deferred tax assets, and investments in the capital of unconsolidated financial institutions that a banking organization did not deduct from CET1 capital. In 2017, the agencies adopted a transition rule to allow non-advanced approaches banking organizations, such as the Corporation and FirstBank, to continue to apply the transition treatment in effect in 2017 (including the 100 percent risk weight for mortgage servicing assets, temporary difference deferred tax assets, and significant investments in the capital of unconsolidated financial institutions, instead of the 250 percent risk weight required under the Basel III rules) while the agencies considered the simplifications proposal. On July 9, 2019, the agencies adopted a final rule that supersedes the regulatory capital transition rules and eliminates the transition provisions that are no longer operative. The final rule was generally effective April 1, 2020, with early adoption permitted on January 1, 2020 and eliminates: (i) the 10% CET1 capital deduction threshold, which applies individually to holdings of mortgage servicing assets, temporary difference deferred tax assets, and significant investments in the capital of unconsolidated financial institutions in the form of common stock; (ii) the 15% common equity tier 1 capital deduction threshold, which applies to the aggregate amount of such items; (iii) the 10% threshold for non-significant investments, which applies to holdings of regulatory capital of unconsolidated financial institutions; and (iv) the deduction treatment for significant investments in the capital of unconsolidated financial institutions that are not in the form of common stock. Instead, the final rule requires non-advanced approaches banking organizations to deduct from CET1 capital any amount of mortgage servicing assets, temporary difference deferred tax assets, and investments in the capital of unconsolidated financial institutions that individually exceeds 25% of CET1 capital of the banking organization (the 25% CET1 capital deduction threshold). The final rule retains the requirement that a banking organization must apply a 250% risk weight to non-deducted mortgage servicing assets or temporary difference deferred tax assets. As part of its response to the impact of COVID-19, on March 31, 2020, the Federal Reserve, Federal Deposit Insurance Corporation and Office of the Comptroller of the Currency 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 the day 1 impact to retained earnings plus 25% of the change in the ACL (excluding PCD loans) 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. Accordingly, as of March 31, 2020, the capital measures of the Corporation and the Bank exclude the $62.3 million day 1 impact to retained earnings and 25% of the increase in the allowance for credit losses (as defined in the interim final rule) from January 1, 2020 to March 31, 2020. 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 measures cannot be predicted at this time. The regulatory capital positions of the Corporation and FirstBank as of March 31, 2020, which reflects the delay in the effect of CECL on regulatory capital, and December 31, 2019 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, 2020 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 2,305,042 25.42% $ 725,557 8.0% N/A N/A FirstBank $ 2,259,012 24.91% $ 725,384 8.0% $ 906,730 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,976,105 21.79% $ 408,126 4.5% N/A N/A FirstBank $ 1,836,831 20.26% $ 408,029 4.5% $ 589,375 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 2,012,209 22.19% $ 544,168 6.0% N/A N/A FirstBank $ 2,144,831 23.65% $ 544,038 6.0% $ 725,384 8.0% Leverage ratio First BanCorp. $ 2,012,209 15.98% $ 503,686 4.0% N/A N/A FirstBank $ 2,144,831 17.05% $ 503,138 4.0% $ 628,923 5.0% As of December 31, 2019 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 2,286,337 25.22% $ 725,236 8.0% N/A N/A FirstBank $ 2,242,262 24.74% $ 725,047 8.0% $ 906,309 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,957,887 21.60% $ 407,946 4.5% N/A N/A FirstBank $ 1,820,571 20.09% $ 407,839 4.5% $ 589,101 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 1,993,991 22.00% $ 543,927 6.0% N/A N/A FirstBank $ 2,128,571 23.49% $ 543,785 6.0% $ 725,047 8.0% Leverage ratio First BanCorp. $ 1,993,991 16.15% $ 493,786 4.0% N/A N/A FirstBank $ 2,128,571 17.26% $ 493,242 4.0% $ 616,552 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, 2020, commitments to extend credit amounted to approximately $1.4 billion, of which $692.4 million relates to credit card loans. Commercial and financial standby letters of credit amounted to approximately $73.9 million. As of the date hereof, the amount of draws from unfunded loan commitments has not increased significantly due to the COVID-19 pandemic. As of March 31, 2020, 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, 2020, no such disclosures were necessary.

Loan Deferral Program Description		In working with borrowers affected by the COVID-19 pandemic, the Corporation implemented payment deferral programs to alleviate the hardships being experienced by the Corporation’s borrowers. The payment deferral programs, which the Corporation implemented in March 2020, provided deferred repayment arrangements across-the-board up to June 30, 2019 to consumer borrowers (i.e., residential mortgage, personal loans, auto loans, finance leases, small loans, and credit cards) who qualify for the program based, among other things, on the delinquency status of the loan on March 16, 2019, and who did not make their payment corresponding to the month of March, with the possibility of extension up to August 31, 2020, if needed. For commercial loans, any request for payment deferral is analyzed on a case by case basis.

However, the participants may vest with respect to 50% of the awards to the extent that performance is below the target but at 80% of the pre-established performance target level (the “80% minimum threshold”), which is measured based upon the growth in the tangible book value during the performance cycle. If performance is between the 80% minimum threshold and the pre-established performance target level, the participants will vest on a proportional amount. No performance units will vest if performance is below the 80% minimum threshold.

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 servicing asset 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 there is no legal surplus reserve 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.
