Accounting Policies [Abstract]

These reclassifications include, but are not limited to, the amount of deferred tax assets, net of valuation allowance, that was p reviously presented as part of other assets, was reclassified and is presented separately in the statements of financial condition, the amount of the FDIC insurance premium expense, that was previously presented as part of Insurance and supervisory fees, w as reclassified and is presented separately in the statements of income, and the amount of supervisory fees and other insurance expenses, that was previously presented as part of Insurance and supervisory fees, was reclassified and is presented as part of Other interest non-interest expenses in the statements of income. These reclassifications had no impact on the previously reported results of operations, financial condition, or cash flows. NOTE 1 – NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The following is a description of First BanCorp.’s (“First BanCorp.” or “the Corpora tion”) most significant policies: Nature of business First BanCorp. is a publicly owned, Puerto Rico-chartered financial holding company that is subject to regulation, supervision, and examination by the Board of Governors of the Federal Reserve System ( the “Federal Reserve Board”). The Corporation is a full service provider of financial services and products with operations in Puerto Rico, the United States, the U.S. Virgin Islands ( “ USVI ” ), and the British Virgin Islands ( “ BVI ” ). The Corporation provi des a wide range of financial services for retail, commercial, and institutional clients. As of December 31, 2018, the Corporation controlled two wholly-owned subsidiaries: FirstBank Puerto Rico (“FirstBank” or the “Bank”), and FirstBank Insurance Agency, Inc. (“FirstBank Insurance Agency”). FirstBank is a Puerto Rico-chartered commercial bank, and FirstBank Insurance Agency is a Puerto Rico-chartered insurance agency. FirstBank is subject to the supervision, examination, and regulation of both the Office of the Commissioner of Financial Institutions of the Commonwealth of Puerto Rico (“OCIF”) and the Federal Deposit Insurance Corporation (the “FDIC”). Deposits are insured through the FDIC Deposit Insurance Fund. FirstBank also operates in the state of F lorida (USA), subject to regulation and examination by the Florida Office of Financial Regulation and the FDIC, in the USVI, subject to regulation and examination by the United States Virgin Islands Banking Board, and in the BVI, subject to regulation by t he British Virgin Islands Financial Services Commission. The Consumer Financial Protection Bureau (“CFPB”) regulates FirstBank’s consumer financial products and services. FirstBank Insurance Agency is subject to the supervision, examination, and regulatio n of the Office of the Insurance Commissioner of the Commonwealth of Puerto Rico. As of December 31, 2018, FirstBank conducts its business through its main office located in San Juan, Puerto Rico, 46 banking branches in Puerto Rico, 11 banking branches in the USVI and the BVI, and 10 banking branches in the state of Florida (USA). As of December 31, 2018, FirstBank has 6 wholly owned subsidiaries with operations in Puerto Rico: First Federal Finance Corp. (d/b/a Money Express La Financiera), a finance co mpany specializing in the origination of small loans with 28 offices in Puerto Rico; First Management of Puerto Rico, a domestic corporation, which holds tax-exempt assets; FirstBank Puerto Rico Securities Corp. (“FirstBank Securities”) , a subsidiary forme rly engaged in broker-dealer activities; FirstBank Overseas Corporation, an international banking entity organized under the International Banking Entity Act of Puerto Rico; and two other companies that hold and operate certain other real estate owned (“OR EO”) properties. On August 1, 2018, the Bank’s Board of Directors approved a resolution to dissolve the broker-dealer subsidiary FirstBank Securities. Accordingly, FirstBank Securities filed the required Form BDW for the withdrawal of its registration from the SEC and the Financial Industry Regulatory Authority and its license to operate as broker-dealer was terminated effective September 30, 2018. Management is in the process of completing the dissolution of FirstBank Securities as a legal entity under the state laws. Principles of consolidation The consolidated financial statements include the accounts of the Corporation and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Statutory business trusts that are wholly- owned by the Corporation and are issuers of trust-preferred securities, and entities in which the Corporation has a non-controlling interest, are not consolidated in the Corporation’s consolidated financial statements in accordance with authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) for consolidation of variable interest entities (“VIE”). See “Variable Interest Entities” below for further details regarding the Corporation’s accounting policy for these entities . Use of estimates in the preparation of financial statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets , liabilities and contingent liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results cou ld differ from those estimates. Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from the Federal Reserve Bank of New York (the “New York FED” or “Federal Reserve”) and other depository instituti ons. The term also includes money market funds and short-ter m investments with original maturities of three months or less and time deposits with original maturities of twelve months or less. Time deposits considered cash and cash equivalent are highly liquid and readily convertible to cash . 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 Corpo ration 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 December 31, 201 8 and 201 7 , 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 other comprehensive income (“OCI”) as a separate component of stockholders’ equity, and do not affect earnings until they are realized or are deemed to be other-than-temporarily impaired. E quity securities — Equity securities that do not have readily available fair values are classified as other 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 stock that is owned by th e Corporation to comply with Federal Home Loan Bank ( “ FHLB ” ) regulatory requirements. Their realizable value equals their cost. Also included in this category are marketable equity securities held at fair value with changes in unrealized gains or losses r ecorded through earnings pursuant to the requirements of ASU 2016-01. 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. Net realized gains and losses and valuation adjustments considered other-than-temporary, if any, related to inv estment securities are determined using the specific identification method and are reported in non-interest income as net gain (loss) on sale of investments and net impairment losses on debt securities, respectively. Purchases and sales of securities are recognized on a trade-date basis. Evaluation of other-than-temporary impairment (“OTTI”) on held-to-maturity and available-for-sale securities On a quarterly basis, the Corporation performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered an OTTI. A security is considered impaired if the fair value is less than its amortized cost basis. The Corporation employs a systematic methodology that considers all available evidence in evaluating a potential impairment of its investments. The impairment analysis of debt securities places special emphasis on the analysis of 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 len gth of time and the extent to which the fair value has been 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 conditio n 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 C orporation 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 o f cash flows generated from the underlying collateral, if any, supporting the principal and interest payments of the debt securities. OTTI must be recognized in earnings if the Corporation has the intent to sell the debt security or it is more likely than not that it will be required to sell the debt security before recovery of its amortized cost basis. However, even if the Corporation does not expect to sell a debt security, it must evaluate expected cash flows to be received and determine if a credit los s has occurred. An unrealized loss is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. For available-for-sal e and held-to-maturity debt securities the Corporations intends to hold, the credit loss component of an OTTI, if any, is recorded as net impairment losses on debt securities in the statements of income, while the remaining portion of the impairment loss i s recognized in OCI, net of taxes, and included as a component of stockholders’ equity . The previous amortized cost basis less the OTTI recognized in earnings is the new amortized cost basis of the investment. The new amortized cost basis is not adjusted f or subsequent recoveries in fair value. Subsequent increases and decreases (if not an OTTI) in the fair value of available-for-sale securities is included in other comprehensive income. For held-to-maturity debt securities, any OTTI recognized in OCI shou ld be accreted from other comprehensive income to the amortized cost of the debt security over the remaining life of the debt security. However, debt securities for which OTTI was recognized in earnings, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income as long as th e security is not placed in nonaccrual status. Debt securities held by the Corporation at year-end primarily consisted of securities issued by U.S. government-sponsored entities, private label mortgage-backed securities (“MBS”) , certain bonds issued by the Puerto Rico Housing Finance Authority, a government instrumentality of the Commonwealth of Puerto Rico, and obligations of certain municipalities in Puerto Rico . Given the explicit and implicit guarantees provided by the U.S. f ederal government, the Corporation believes the credit risk in securities issued by the U.S. government-sponsored entities is low. The Corporation’s OTTI assessment was concentrated on Puerto R ico government debt securities and private label MBS. For further information, including methodology and assumptions used for the discounted cash flow analyses performed on these securities, refer to Note 5 – Investment Securities, to the consolidated financi al statements. 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. The substantial majority of the Corporation’s loans are classified as held for investment. Loans are stated at the principal outstanding balance, net of unearned interest, cumulative charge-offs, u namortized deferred origination fees and costs, and unamortized premiums and discounts. 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. Credit card loans are reported at their outstanding unpaid principal balance plus uncollected billed interest and fees net of amounts deemed uncollectible. Purcha sed Credit Impaired (“ PCI ”) loans are reported net of any remaining purchase accounting adjustments. See “Loans Acquired” below for the accounting policy for PCI loans. Non accrual and Past-Due Loans - Loans on which the recognition of interest income has been discontinued are designated as non accrual . Loans are classified as non accrual 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”) or the Veterans Administration (the “VA”) and credit cards. It is the Corporation’s policy to report delinquent mortgage loans insured by the FHA , or guarantee d by the VA or the Puerto Rico Housing Authority, as loans past due 90 days and still accruing as op posed to non accrual loans since the principal repayment is insured. However, the Corporation discontinues the recognition of income for FHA/VA loans when such loans are over 15 months delinquent , taking into consideration the FHA interest curtailment proce ss, and for loans guaranteed by the Puerto Rico Housing Finance Authority when such loans are over 90 days delinquent. As permitted by regulatory guidance issued by the Federal Financial Institutions Examination Council (“FFIEC”), credit card loans are gen erally charged off in the period in which the account becomes 180 days past due. Credit card loans continue to accrue finance charges and fees until charged off at 180 days. Loans generally may be placed on non accrual status prior to when required by the p olicies 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 non accrual stat us, any accrued but uncollected interest income is reversed and charged against interest income and amortization of any net deferred fees is suspended. Interest income on non accrual loans is recognized only to the extent it is received in cash. However, wh en 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). 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. PCI loans are not reported as nonaccrual as these loans were written down to fair value at the acquisition date and the accretable yield is recognized in interest income over the remaining life of the loans. 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 payments. Impaired Loans - A loan is considered impaired when, based upon current information and events, it is probable that the Corporation will be unable to collect all amounts due (including principal and interest) according to the contr actual terms of the loan agreement, or the loan has been modified in a Troubled Debt Restructuring (“TDR”). Loans with insignificant delays or insignificant shortfalls in the amounts of payments expected to be collected are not considered to be impaired. T he Corporation evaluates individually for impairment those loans in the construction, commercial mortgage, and commercial and industrial portfolios of $1 million or more as well as any boat loan of $1 million or more. Although the authoritative accounting guidance for a specific impairment of a loan excludes large groups of smaller balance homogeneous loans that are collectively evaluated for impairment ( e.g. , mortgage an d consumer loans), it specifically requires that loan modifications considered TDR s be analyzed under its provision. The Corporation also evaluates for impairment purposes certain residential mortgage loans and home equity lines of credit with high delinqu ency and loan to value levels. Held-for-sale loans are not reported as impaired, as these loans are recorded at the lower of cost or fair value. The Corporation generally measures impairment and the related specific allowance for individually impaired lo ans based on the difference between the recorded investment of the loan and the present value of the loans’ expected future cash flows, discounted at the effective original interest rate of the loan at the time of modification, or the loan’s observable mar ket price. If the loan is collateral dependent, the Corporation measures impairment based upon the fair value of the underlying collateral, instead of discounted cash flows, regardless of whether foreclosure is probable. Loans are identified as collateral dependent if the repayment is expected to be provided solely by the underlying collateral, through liquidation or operation of the collateral. When the fair value of the collateral is used to measure impairment on an impaired collateral-dependent loan and repayment or satisfaction of the loan is dependent on the sale of the collateral, the fair value of the collateral is adjusted to consider estimated costs to sell. If repayment is dependent only on the operation of the collateral, the fair value of the col lateral is not adjusted for estimated costs to sell. If the fair value of the loan is less than the recorded investment, the Corporation recognizes impairment by either a direct write-down or establishing a specific allowance for the loan or by adjusting t he specific allowance for the impaired loan. For an impaired loan that is collateral dependent, charge-offs are taken in the period in which the loan, or a portion of the loan, is deemed uncollectible, and any portion of the loan that is not charged off is adversely credit-risk rat ed at a level no worse than substandard. A restructuring of a loan constitutes a TDR if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. TDR loans typically result from the Corporation’s loss mitigation activities and the modification of residential mortgage loans in accordance with guidelines similar to those of the U.S. government’s Home Affordable Modification Pro gram, and could include rate reductions to a rate that is below market on the loan, principal forgiveness, term extensions, payment forbearance, refinancing of any past-due amounts, including interest, escrow, and late charges and fees, and other actions i ntended to minimize the economic loss and to avoid foreclosure or repossession of collateral. Residential mortgage loans for which a binding offer to restructure has been extended are also classified as TDR loans. PCI loans are not classified as TDR loans. TDR loans are classified as either accrual or nonaccrual loans . Loans in accrual status may remain in accrual status when their contractual terms have been modified in a TDR if the loans had demonstrated performance prior to the restructuring and payment in full under the restructured terms is expected. Otherwise , loans on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure, generally for a minimum of six m onths , and there is evidence that such payments , can , and ar e likely to, continue as agreed. Refer to Note 8 – Loans Held for Investment ,” to the consolidated financial statements for additional qualitative and quantitative information about TDR loans. In connection with commercial loan restructurings, the decision to maintain a loan that has been restructured on accrual status is based on a current, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. The credit evaluation reflects consideration of the borrower’s future capacity to pay, which may include evaluation of cash flow projections, consideration of the adequacy of collateral to cover all principal and interest, and trends i ndicating improving profitability and collectability of receivables. This evaluation also includes an evaluation of the borrower’s current willingness to pay, which may include a review of past payment history, an evaluation of the borrower’s willingness t o provide information on a timely basis, and consideration of offers from the borrower to provide additional collateral or guarantor support. The evaluation of mortgage and consumer loans for restructurings includes an evaluation of the client’s disposab le income and credit report, the value of the property, the loan-to-value relationship, and certain other client-specific factors that have affected the borrower’s ability to make timely principal an d interest payments on the loan . The Corporation remove s loans from TDR classification, consistent with authoritative guidance that allows for a TDR to be removed from this classification in years following the modification, only when the following two circumstances are met: The loan is in compliance with the terms of the restructuring agreement and, therefore, is not considered impaired under the revised terms; and The loan yields a market interest rate at the time of the restructuring. In other words, the loan was restructured with an interest rate equal to or greater than what the Corporation would have been willing to accept at the time of the restructuring for a new loan with comparable risk. If both of the conditions are met, the loan can be removed from the TDR classification in calendar years after th e year in which the restructuring took place. However, the loan continues to be individually evaluated for impairment. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. With respect t o the restructuring of a loan into two new loan notes, or loan splits, g enerally Note A of a loan split is restructur ed under market terms, and Note B is fully charged off. If Note A is in compliance with the restructured terms in years following the restructuring, Note A will be removed from the TDR classification and will continue to be individually evaluated for impairment. Refer to Note 8 – Loans Held for Investment, to the consolidated financial statements , for additional information about loan splits. A loan that had previously been modified in a TDR and is subsequently refina nced under current underwriting standards at a market rate with no concessionary terms is accounted for as a new loan and is no longer reported as a TDR. Interest income on impaired loans is recognized based on the Corporation’s policy for recogniz ing int erest on accrual and non accrual loans. Loans Acquired - All purchased loans are recorded at fair value at the date of acquisition. Loans acquired with evidence of credit deterioration since their origination and where it is probable at the date of acquisit ion that the Corporation will not collect all contractually required principal and interest payments are considered PCI loans. Evidence of credit quality deterioration as of the purchase date may include stat istics such as past due and non accrual status, c redit scores, and revised loan terms. PCI loans have been aggregated into pools based on common risk characteristics. Each pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. In accounti ng for PCI loans, the difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. The nonaccretable difference, which is neither accreted into income nor reco rded on the consolidated statements of financial condition, reflects estimated future credit losses expected to be incurred over the life of the pool of loans. The excess of cash flows expected to be collected over the estimated fair value of PCI loans is referred to as the accretable yield. This amount is not recorded on the statements of financial condition, but is accreted into interest income over the remaining life of the pool of loans, using the effective-yield method. Subsequent to acquisition, the Corporation continues to estimate cash flows expected to be collected over the life of the PCI loans using models that incorporate current key assumptions such as default rates, loss severity, and prepayment speeds. Decreases in expected cash flows will generally result in an impairment charge to the provision for loan and lease losses and the establishment of an allowance for loan and lease losses. Increases in expected cash flows will generally result in a reduction in any a llowance for loan and lease losses established subsequent to acquisition and an increase in the accretable yield. The adjusted accretable yield is recognized in interest income over the remaining life of the pool of loans. Resolutions of loans may include sales of loans to third parties, receipt of payments in settlement with the borrower, or foreclosure of the collateral. The Corporation’s policy is to remove an individual loan from a pool at its relative carrying amount. The carrying amount is defined as the loan’s current contractually required payments receivable less its remaining nonaccretable difference and accretable yield, but excluding any post-acquisition loan loss allowance. To determine the carrying value, the Corporation performs a pro-rata al location of the pool’s total remaining nonaccretable difference and accretable yield to an individual loan in proportion to the loan’s current contractually required payments receivable compared to the pool’s total contractually required payments receivabl e. This removal method assumes that the amount received from resolution approximates pool performance expectations. The remaining accretable yield balance is unaffected and any material change in the remaining effective yield caused by this removal method is addressed by the Corporation’s quarterly cash flow evaluation process for each pool. Modified PCI loans are not removed from a pool even if those loans would otherwise be deemed TDRs. Because the initial fair value of PCI loans recorded at acquisition includes an estimate of credit losses expected to be realized over the remaining lives of the loans, the Corporation separately tracks and reports PCI loans and excludes these loans from its delinquency and non accrual loan statistics. For acquired loans that are not deemed impaired at acquisition, subsequent to acquisition, the Corporation recognizes the difference between the initial fair value at acquisition and the undiscounted expected cash flows in interest income over the period in which substantial ly all of the inherent losses associated with the non-PCI loans at the acquisition date are estimated to occur. Thus, such loans are accounted for consistently with other originated loans, potentially being classified as nonaccrual or impaired, as well as being classified under the Corporation’s standard practice and procedures. In addition, these loans are considered in the determination of the allowance for loan losses. Charge-off of Uncollectible Loans - Net charge-offs consist of the unpaid principal balances of loans held for investment that the Corporation determines are uncollectible, net of recovered amounts. Charge-offs are recorded as a reduction to the allowance for loan and lease losses and subse quent recoveries of previously charged off amounts are credited to the allowance for loan and lease losses. Collateral dependent loans in the construction, commercial mortgage, and commercial and industrial loan portfolios are charged off to their net real izable value (fair value of collateral, less estimated costs to sell) when loans are considered to be uncollectible. Within the consumer loan portfolio, auto loans and finance leases are reserved once they are 120 days delinquent and are charged off to th eir estimated net realizable value when the collateral deficiency is deemed uncollectible ( i.e. , when foreclosure/repossession is probable) or when the loan is 365 days past due. Within the other consumer loan portfolio , closed-end loans are charged off w hen payments are 120 days in arrears, except small personal loans. Open-end (revolving credit) consumer loans, including credit card loans, and small personal loans are charged off when payments are 180 days in arrears. On a quarterly basis, residential mo rtgage loans that are 180 days delinquent and have an original loan-to-value ratio that is higher than 60% are reviewed and charged-off, as needed, to the fair value of the underlying collateral. Generally, all loans may be charged off or written down to t he fair value of the collateral prior to the application of the policies described above if a loss-confirming event has occurred. Loss-confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, or receipt of an asset valuation indicating a collateral deficiency when the asset is the sole source of repayment. The Corporation does not record charge-offs on PCI loans that are performing in accordance with or better than expectations as of the date of acquisition, as the f air value of these loans already reflects a credit component. The Corporation records charge-offs on PCI loans only if actual losses exceed estimated losses incorporated into the fair value recorded at acquisition and the amount is deemed uncollectible. L oans held for sale Loans that the Corporation intends to sell or that the Corporation does not have the ability and intent to hold for the foreseeable future are classified as held-for-sale loans. Loans held for sale are stated at the lower of aggregate c ost or fair value. Generally, the loans held-for-sale portfolio consists of conforming residential mortgage loans that the Corporation intends to sell to the Government National Mortgage Association (“GNMA”) and government-sponsored entities (“GSEs”)

Update On Effects Of Natural Disasters [Abstract]
Natural Disasters [Text Block]	NOTE 2 – EFFECTS OF NATURAL DISASTERS Two strong hurricanes affected the Corporation’ s service areas during 2017. Early in September, Hurricane Irma, a Category 5 hurricane, affected the eastern Caribbean islands, including the U.S. Virgin Islands of St. Thomas and St. John and Tortola in the British Virgin Islands and, to a lesser extent, the U.S. Virgin Island of S t. Croix and Puerto Rico. After hitting the eastern Caribbean, Hurricane Irma made landfall along Florida’s southwest shoreline. Two weeks after Hurricane Irma sideswiped Puerto Rico, Hurricane Maria made landfall in the south east corner of Puerto Rico a s a Category 4 hurricane and exited on the northern coast at a point between the cities of Arecibo and Barceloneta after battering other islands in the Caribbean, including St. Croix. These hurricanes caused widespread property damage, flooding, power out ages, water and communicat ion services interruptions, and severely disrupted normal economic activi ty in all of these regions. The following summarizes the more significant financial repercussions of these natural disasters for the Corporation and for its major subsidiary, FirstBank. Credit Quality and Allowance for Loan and Lease Losses During the third quarter of 2017, the Corporation recorded a $ 66.5 million charge to the provision for loan and lease losses related to the establishment of qualitative res erves associated with the effects of Hurricanes Irma and Maria. During the fourth quarter of 2017, commercial loan officers performed reviews of the hurricanes’ effect on large commercial borrowers, and the results of these reviews were factored into the d etermination of the allowance for loan and lease losses as of December 31, 2017. Relationship officers have continued to closely monitor the performance of hurricane-affected commercial loan customers during 2018. Information provided by these commercial loan officers and statistics on the performance of consumer and residential credits were factored into the determination of the allowance for loan and lease losses as of December 31 , 2018. Although the identification and evaluation of hurricane-affected cr edits has been completed, management’s assessment of the hurricanes’ effect is still subject to uncertainties, both those specific to some individual customers, such as the resolution of insurance claims, and those applicable to the overall economic prospe cts of the hurricane-affected areas as a whole. During 2018, the Corporation recorded a net loan loss reserve release of approximately $ 16.9 million in connection with revised estimates associated with the effects of the hurricanes. The revised estimates w ere primarily attributable to updated assessments of financial performance and repayment prospects of certain individually-assessed commercial credits, updated payment patterns and probability of default credit risk analyses applied to consumer borrowers, and lower reserve requirements resulting from payments received during 2018 that reduced the balance of the consumer and residential mortgage loan portfolios outstanding on the dates of the hurr icanes. The individual review of large commercial loans also resulted in downgrades in the credit risk classification of certain loans and their hurricane-related qualitative reserves of approximately $ 5.7 million were transferred to the general reserve and the ir reserve s are now determined following the methodology applicable to criticized and adversely cla ssified loans, as appropriate. In addition, consumer loan charge-offs totaling $ 10.9 million were taken against previously established hurricane-related qualitative reserves. These charge offs were directly linked to the performance of consumer borrowers that were subject to payment deferral programs. As of December 31 , 2018, the hurricane-related qualitative allowance amounted to $ 19.2 million (December 31, 2017 - $ 55.6 million). With the future resolution of unc ertainties and the ongoing collection of information on individual commercial customers and statistics on the consumer and residential loan portfolios, the loss estimate will be re vised as needed. Refer to Note 9 - Allowance for Loan and Lease Losses, to t he consolidated financial statements , for information about the determination of the hurricane-related qualitative reserves. Disaster Response Plan Costs, Casualty Losses and Related Insurance The Corporation incurred a variety of costs to operate in disa ster response mode, and some facilities and their contents, including certain OREO properties, were damaged by the storms. The Corporation maintains insurance for casualty losses, as well as for reasonable and necessary disaster response costs and certain revenue lost through business interruption. Insurance claim receivables were established for some of the individual costs, when incurred, based on management’s understanding of the underlying coverage and when realization of the claim was deemed probable. During 2018, the Corporation reached settlement on certain insurance claims arising from the hurricanes. As a result, the Corporation received insurance proceeds of approximately $ 6.8 million, primarily related to impairments, repairs and maintenance costs incurred on some facilities, including certain OREO properties, $ 1.0 million related to recoveries of disaster response costs, and $ 0.8 million related to a loan receivable fully charged-off in prior periods. The insurance proceeds were recorded agai nst incurred losses, previously-established accounts receivable, or loan recoveries, as applicable. Insurance recoveries are recorded in the same income statement caption as the incurred losses. Recoveries from insurance proceeds in excess of losses incurr ed, amounting to $ 0.5 million for 2018, were recognized as a gain from insurance proceeds and reported as part of “other non-interest income” in the statement of income . As of December 31 , 2018, the Corporation still had an insurance claim receivable of $ 3 .4 million (December 31, 2017 - $ 4.8 million) , included as part of “other assets” in the statement of financial condition. Management also believes that there is a possibility that some gains will be recognized with respect to casualty and lost revenue cla ims in future periods, but this is contingent on reaching agreement on the Corporation’s claims with the insurance carriers. Liquidity Management The Corporation experienced rapid accumulation of deposits after the hurricanes in the fourth quarter of 2017 and during 2018. Total deposits as of December 31 , 2018, excluding brokered CDs, increased $ 567.0 million from December 31, 2017 and $ 928.5 million since September 30, 2017. The most significant increase was in non-interest- bearing demand deposits, which grew 31 %, or $ 561.8 million, from December 31, 2017 and 51 %, or $ 809.3 million, since September 30, 2017. Hurricane-related factors, such as the effect of disaster relief funds and settlements of insurance claims, contribute d to this growth. Although management expects the balances accumulated by deposit customers in the hurricane-affected areas to reduce over time, it is difficult to predict when and to what degree, and there may be further growth as insurance claims are re solved and additional disaster-recovery funds are distributed.

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 and the noncredit loss component of OTTI are presented as part of OCI. The aggregate amortized cost and approximate market value of investment securities available for sale as of December 31, 2018 by contractual maturity, are shown below: Amortized Cost Fair Value (Dollars in thousands) United States Puerto Rico government obligations and other debt securities: Within 1 year $ 199,020 $ 197,079 After 1 to 5 years 185,351 183,305 After 5 to 10 years 199,750 198,490 After 10 years 38,812 37,234 622,933 616,108 MBS and Collateralized Mortgage Obligations (1) 1,352,297 1,326,460 Total investment securities available for sale $ 1,975,230 $ 1,942,568 (1) The expected maturities of MBS and collateralized mortgage obligations may differ from their contractual maturities because they may be subject to prepayments.

The tables also include debt securities for which an OTTI was recognized and only the amount related to a credit loss was recognized in earnings. For unrealized losses for which OTTI was recognized, the related cred it loss was charged against the amortized cost basis of the debt security.

Assessment for OTTI Debt securities issued by U.S. government agencies, U.S. government-sponsored entities, and the U.S. Treasury accounted for approximately 99 % of the total available-for-sale portfolio as of December 31 , 2018, and no credit losses are expected, given the ex plicit and implicit guarantees provided by the U.S. federal government. The Corporation’s OTTI assessment was concentrated mainly on private label MBS, and on Puerto Rico government debt securities, for which credit losses are evaluated on a quarterly basi s. 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: The length of time and the extent to which the fair value has been 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 princip al 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 recorded OTTI losses on available-for-sale debt securities as follows: Year Ended December 31, 2018 2017 2016 (In thousands) Total OTTI losses $ - $ (12,231) $ (1,845) Portion of OTTI recognized in OCI (50) - (4,842) Net impairment losses recognized in earnings (1) $ (50) $ (12,231) $ (6,687) (1) For the year ended December 31, 2018, the credit impairment of $50 thousand recognized in earnings consisted of credit losses on private label MBS. For the years ended December 31, 2017 and 2016, approximately $12.2 million and $6.3 million, respectively, of the credit impairment recognized in earnings consisted of credit losses on Puerto Rico government debt securities that were sold in the second quarter of 2017, as further discussed below. The remaining impairment losses for the year ended December 31, 2016 were associated with credit losses on private label MBS. The following tables summarize the roll-forward of credit losses on debt securities held by the Corporation for which a portion of an OTTI is also recognized in OCI: Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit loss December 31, recognized in earnings on reductions for December 31, 2017 securities that have been securities sold 2018 Balance previously impaired during the period Balance (In thousands) Available-for-sale securities Private label MBS $ 6,792 $ 50 $ - $ 6,842 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit loss December 31, recognized in earnings on reductions for December 31, 2016 securities that have been securities sold 2017 Balance previously impaired during the period Balance (In thousands) Available-for-sale securities Puerto Rico government obligations $ 22,189 $ 12,231 $ (34,420) $ - Private label MBS 6,792 - - 6,792 Total OTTI credit losses for available-for-sale debt securities $ 28,981 $ 12,231 $ (34,420) $ 6,792 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit loss December 31, recognized in earnings on reductions for December 31, 2015 securities that have been securities sold 2016 Balance previously impaired during the period Balance (In thousands) Available-for-sale securities Puerto Rico government obligations $ 15,889 $ 6,300 $ - $ 22,189 Private label MBS 6,405 387 - 6,792 Total OTTI credit losses for available-for-sale debt securities $ 22,294 $ 6,687 $ - $ 28,981 During the second quarter of 2017, the Corporation sold for an aggregate of $ 23.4 million three Puerto Rico government available-for-sale debt securities, specifically bonds of the Government Development Bank for Puerto Rico (the “GDB”) and the Puerto Rico Public Buildings Authority, carried on its book at an amortized cost at the time of sale of $ 23.0 million (net of $ 34.4 million in cumulative OTTI impairment charges). This transaction resulted in a $ 0.4 million recovery from previous OTTI charges reflected in the consolidated statement of income as part of “net gain on sale of investm ents.” Approximately $ 12.2 million and $ 6.3 million of the cumulative OTTI charges on these securities was recorded in the first quarter of 2017 and the first quarter of 2016, respectively . For the OTTI charge recorded on the Puerto Rico government debt securities during 2017 and 2016 , the Corporation considered the latest available information about the Puerto Rico government’s financial condition, including but not limited to credit ratings downgrades, revised estimates of recovery rates, and other rele vant developments such as government actions, including debt exchange proposals and the fiscal plan published by the Puerto Rico government in March 2017, as applicable. The Corporation applied a discounted cash flow analysis to its Puerto Rico government debt securities in order to calculate the cash flows expected to be collected and to determine if any portion of the decline in market value of these securities was considered a credit-related OTTI. The analysis derived an estimate of value based on the p resent value of risk-adjusted cash flows of the underlying securities and included the following components: The contractual future cash flows of the bonds were projected based on the key terms as set forth in the official statements for each security. Su ch key terms include, among others, the interest rate, amortization schedule, if any, and maturity date. The risk-adjusted cash flows were calculated based on a probability of default analysis and recovery rate assumptions, including the weighting of di fferent scenarios of ultimate recovery, considering the credit rating of each security. Constant monthly default rates were assumed throughout the life of the bonds, which considered the respective security's credit rating as of the date of the analysis. The adjusted future cash flows were then discounted at the original effective yield of each investment based on the purchase price and expected risk-adjusted future cash flows as of the purchase date of each investment. The discounted risk-adjusted cash f low analysis for the three Puerto Rico government bonds mentioned above assumed a default probability of 100 %, as these three non accrual bonds had been in default since the third quarter of 2016. Based on this analysis, the Corporation recorded in the firs t quarter of 2017 credit-related OTTI amounting to $12.2 million, assuming recovery rates ranging from 15 % to 80 % (with a weighted average of 41 %). As of December 31, 2018, the Corporation’s available-for-sale investment securities portfolio includes bonds of the Puerto Rico Housing Finance Authority (“PRHFA”) at an amortized cost of $ 8.2 million (fair value - $ 7.0 million). Approximately $ 4.2 million (fair value - $ 2.8 million) of these bonds consist of residential pass-through mortgage-backe d securities issued by the PRHFA that are collateralized by certain second mortgages originated under a program launched by the Puerto Rico government in 2010. These bonds have been structured as zero-coupon bonds for the first ten years (up to July 2019). Cons idering the absence of any instances of default and the insurance protection provided by the PRHFA to the underlying collateral, management concluded that these obligations were not other-than-temporarily impaired as of December 31, 2018. In a ddition, during 2018 and 2016, the Corporation recorded credit-related impairment losses of $ 50 thousand and $ 0.4 million, respectively, associated with private label MBS , which are collateralized by fixed-rate mortgages on single-family residential proper ties in the United States. 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 mortgages are fixed-rate, single-family loans with original h igh FICO scores (over 700) and moderate loan-to-value ratios (under 80%), as well as moderate delinquency levels. As of As of December 31, 2018 December 31, 2017 Weighted Weighted Average Range Average Range Discount rate 14.5% 14.5% 14.0% 14.0% Prepayment rate 11.4% 3.3% - 20.9% 16.4% 12.0% - 29.0% Projected Cumulative Loss Rate 3% 0% - 6.8% 3% 0% - 6.8% Refer to Note 29 – Fair Value, for additional information about the valuation model for private label MBS. Total proceeds from the sale of securities available for sale during 2018, 2017 and 2016 amounted to approximately $ 47.8 million, $ 23.4 million and $ 219.8 million, respectively. Total proceeds from sales in 2018 consisted of proceeds of $ 36.2 million on the sale of U.S. agency MBS and $ 11.6 million on the sale of U.S. agency callable debt securities . For the year ended December 31, 2018, the Corporation recorded a loss of approximately $ 59 thousand on the sale of U.S agency MBS and a gain of approximately $ 22 thousand on the sale of the U.S. agency callable debt securities. In 2017, the Corporation recorded a $0.4 million recovery from pr evious OTTI charges on the sale of Puerto Rico government debt securities with an amortized cost of $23.0 million. Total proceeds from sales in 2016 consisted of proceeds of $ 204.8 million on the sale of U.S. agency MBS and $ 15.0 million on the sale of a U.S. Treasury Security. For the year ended December 31, 2016, the Corporation recorded a $ 6.1 million gain on the sale of U.S. agency MBS and an $ 8 thousand gain on the sale of the U.S. Treasury security. The following table states the names of issuers, and the aggregate amortized cost and market value of the securities of such issuers, when the aggregate amortized cost of such securities exceeds 10 % of the Corporation’s stockholders’ equity. This information excludes securities of the U.S. and Puerto Rico government. Investments in obligations issued by a state of the U.S. and its political subdivisions and agencies that are payable and secured by the same source of revenue or taxing authority, oth er than the U .S. government, are considered securities of a single issuer and include debt and mortgage-backed securities .

A security with similar characteristics traded in the open market is used as a proxy for each municipal bond. Then the cash flow is discounted at the average spread over the discount curve exhibited by th e proxy security at the end of each quarter, plus any corresponding discount rate adjustments to reflect recent transactions or market yield expectations for these type of transactions. All of the Puerto Rico Municipal Bonds are performing and current as to scheduled contractual payments as of December 31 , 2018. 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 independe nt 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. The Corporation performs periodic credit qualit y reviews on these issuers. Based on the quarterly analysis performed, management concluded that no individual debt security held to maturity was other-than-temporarily impaired as of December 31 , 2018. The Financial Oversight and Management Board for P uerto Rico (the “PROMESA oversight board”) has not designated any of Puerto Rico’s 78 municipalities as covered entities under the Puerto Rico Oversight, Management, and Economic Stability Act. (“ PROMESA ”) . However, while the latest fiscal plan certified by the PROMESA oversight board did not contemplate a restructuring of th e debt of Puerto Rico’s municipalities, 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 and liquidity shortfalls, or measures included in fiscal plans of other government entities, such as the fiscal plans of the GDB and the Puerto Rico Electric Power Authority (“PREPA”). Given the uncertain effect that the negative fiscal situation of the Puerto Rico central government and the measures taken, or to be taken, by other government entities may have on municipalities, the Corporation cannot be certain whether future impairment charges will be required relating to these securities. From time to time, the Corporation has securities held to maturity with an original maturity of three months or less that are considered cash a nd cash equivalents and are classified as money market investments in the consolidated statements of financial condition. As of December 31 , 2018 and December 31, 2017, the Corporation had no outstanding securities held to maturity that were classified as cash and cash equivalents.

Other Investment Securities [Text Block]	NOTE 6 – EQUITY SECURITIES On January 1, 2018, the Corporation adopted ASU 2016-01, resulting in the reclassification of equity securities with a readily determinable fair value of approximately $ 0.4 million from available-for-sal e investment securities to equity securities in the consolidated statement of financial condition. During 2018, the Corporation measured these equity securities at fair value through earnings resulting in the recognition of marked-to-market losses of $ 9 thousand record ed as part of other non-interest income in the statement of income. Institutions that are members of the Federal Home Loan Bank (“FHLB”) system are required to maintain a minimum investment in FHLB stock. Such minimum investment is calculated as a percent age of aggregate outstanding mortgages, and the FHLB requires an additional investment that is calculated as a percentage of total FHLB advances, letters of credit, and the collateralized portion of outstanding interest-rate swaps. The stock is capital sto ck issued at $ 100 par value. Both stock and cash dividends may be received on FHLB stock. As of December 31, 2018 and 201 7 , the Corporation had investments in FHLB stock with a book value of $ 41.9 million and $ 40.9 million, respectively . Dividend inc ome from FHLB stock for 201 8 , 201 7 , and 201 6 amounted to $ 2.7 million, $ 2.1 million, and $ 1. 5 million, respectively. The FHLB of New York issued the shares of FHLB stock owned by the Corporation. The FHLB of New York is part of the Federal Home Loan Bank System, a national wholesale banking network of 11 regional, stockholder-owned congressionally chartered banks. The FHLBs are all privately capitalized and operated by their member stockholders. The system is supervised by the Federal Housing Finance Agenc y, which ensures that the FHLBs operate in a financially safe and sound manner, remain adequately capitalized and able to raise funds in the capital markets, and carry out their housing finance mission. The Corporation has other equity securities that do not have a readily determinable fair value. The carrying value of such securities was $ 2.2 million as of both December 31, 2018 and 2017 .

In working with borrowers in the Virgin Islands and Puerto Rico affected by Hurricanes Irma and Maria, which made landfall on September 6, 2017 and September 20, 2017, respectively, the Corporation provided three-month deferred repayment arrangements to consumer borrowers (i.e., personal loans, auto loans, finance leases, and credit cards) who were current in their payments or no more than 2 payments in arrears as of the date of the respective hurricane. For residential mortgage loans, th e Corporation entered during the third and fourth quarters of 2017 into deferred payment arrangements on 9,588 residential mortgages totaling $ 1.3 billion as of December 31, 2017 that provided for a three-month payment deferral for those loans current or n o more than 2 payments in arrears as of the date of the events. For both consumer and residential mortgage loans that were subject to the deferral programs, each borrower was required to resume their regularly scheduled loan payment at the end of the defe rral period (January 2018) and the deferred amounts were move to the end of the loan. The payment deferral programs were applied prospectively from the date of the events and did not change the delinquency status of the loans as of such dates. Also in 20 17, the Corporation, on a case by case basis, entered into three-month deferral arrangements on 351 commercial and construction loans that were current in payments at the date of the event totaling $ 1.2 billion as of December 31, 2017.

The Corporation’s commercial and construction loans credit quality indicators as of December 31, 2018 and 2017 are summarized below: Commercial Credit Exposure-Credit Risk Profile Based on Creditworthiness Category: Substandard Doubtful Loss Total Adversely Classified (1) Total Portfolio December 31, 2018 (In thousands) Commercial mortgage $ 276,935 $ 1,701 $ - $ 278,636 $ 1,522,662 Construction: Land 7,407 - - 7,407 20,313 Construction-commercial - - - - 47,965 Construction-residential 2,102 - - 2,102 11,151 Commercial and Industrial 45,274 6,114 396 51,784 2,148,111 Commercial Credit Exposure-Credit Risk Profile Based on Creditworthiness Category: Substandard Doubtful Loss Total Adversely Classified (1) Total Portfolio December 31, 2017 (In thousands) Commercial mortgage $ 257,503 $ 4,166 $ - $ 261,669 $ 1,614,972 Construction: Land 15,971 490 - 16,461 26,931 Construction-commercial 35,100 - - 35,100 76,556 Construction-residential 1,987 - - 1,987 7,910 Commercial and Industrial 154,416 3,854 676 158,946 2,083,253 (1) Excludes nonaccrual loans held for sale of $16.1 million ($11.4 million commercial mortgage, $3.0 million construction-commercial, and $1.7 million commercial and industrial) and $8.3 million (construction-land) as of December 31, 2018 and December 31, 2017, respectively. The Corporation considers a loan as adversely classified if its risk rating is Substandard, Doubtful, or Loss. These categories are defined as follows: 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 de bt. 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 adde d 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 expos ures 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 t he future. There is little or no prospect for near term improvement and no realistic strengthening action of significance pending . In addition, the Corporation had $ 257.8 million in commercial and construction loans rated as Special Mention (2017 - $ 354.7 million). A Special Mention assets 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 posi tion at some future date. Special Mention assets are not adversely classified and do not expose the Corporation sufficient risk to warrant adverse classification. The Corporation periodically reviews its loans classification to evaluate if they are properl y 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. In addition, during the renewal and annual review process of a pplicable credit facilities, the Corporation evaluates the corresponding loan grades. 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 perfor ms annual comprehensive credit process reviews of the Bank’s commercial portfolios. This group evaluates the credit risk profile of portfolios, including the assessment of the risk rating representative of the current credit quality of the loans, and the e valuation of collateral documentation. 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 effectiv eness 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.

For the year ended December 31, 2017, includes a charge-off of $10.7 million related to the sale of the PREPA credit line and, for the year ended December 31, 2016, includes $4.2 million of charge-offs related to impaired loans included in a sale of a $16.3 million pool of non-performing assets. PCI Loans The Corporation acquired PCI loans accounted for under ASC Topic 310-30 , “Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC Topic 310-30”), as part of a transaction that closed on February 27, 2015 in which FirstBank acquired 10 Puerto Ric o branches of Doral Bank, and acquired certain assets, including PCI loans, and assumed deposits, through an alliance with Banco Popular of Puerto Rico, that was the successful lead bidd er with the FDIC on the failed Doral Bank, as well as other co-bidders. The Corporation also acquired PCI loans in previously completed asset acquisitions that are accounted for under ASC Topic 310-30. These previous transactions include the acquisition fr om Doral Financial in the second quarter of 2014 of all its rights, title and interest in first and second residential mortgage s loans in full satisfaction of secured borrowings owed by such entity to FirstBank. Under AS C Topic 310-30, the acquired PCI l oans were aggregated into pools based on similar characteristics ( i.e. , delinquency status and loan terms). Each loan pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. Since the loans are accounted for under ASC Topic 310-30, they are not considered non accrual and will continue to have an accretable yield as long as there is a reasonable expectation about the timing and amount of cash flows expected to be collected. The Corporation reco gnizes additional losses on this portfolio when it is probable that the Corporation will be unable to collect all cash flows expected as of the acquisition date plus additional cash flows expected to be collected arising from changes in estimates after the acquisition date. The carrying amounts of PCI loans were as follows: As of As of December 31, December 31, 2018 2017 (In thousands) Residential mortgage loans $ 143,176 $ 153,991 Commercial mortgage loans 3,464 4,183 Total PCI loans $ 146,640 $ 158,174 Allowance for loan losses (11,354) (11,251) Total PCI loans, net of allowance for loan losses $ 135,286 $ 146,923 The following tables present PCI loans by past due status as of December 31, 2018 and 2017: As of December 31, 2018 30-59 Days 60-89 Days 90 days or more Total Past Due Total PCI loans Current (In thousands) Residential mortgage loans $ - $ 6,979 $ 26,932 $ 33,911 $ 109,265 $ 143,176 Commercial mortgage loans - - 2,512 2,512 952 3,464 Total (1) $ - $ 6,979 $ 29,444 $ 36,423 $ 110,217 $ 146,640 _____________ (1) 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 and commercial mortgage loans are considered past due when the borrower is in arrears two or more monthly payments. PCI residential mortgage loans past due 30-59 days as of December 31, 2018 amounted to $11.6 million. No PCI commercial mortgage loan was 30-59 days past due as of December 31, 2018.

PCI residential mortgage loans and PCI commercial mortgage loans past due 30-59 days as of December 31, 2017 amounted to $28.1 million and $0.2 million, respectively. Initial Fair Value and Accretable Yield of PCI Loans At acquisition of PCI loans , the Corporation estimated the cash flows the Corporation expected to collect on the loans. Under the accounting guidance for PCI loans, the difference between the contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference.

However, the Corporation separately tracks and reports PCI loans and excludes these loans from the amounts of nonaccrual loans, impaired loans, TDRs and non-performing assets. As of December 31, 2018 , the Corporation maintained a $ 0.4 million reserve for unfunded loan commitments ( compared to $ 0.7 million as of December 31, 2017 ), mainly related to outstanding commitments on floor plan revolving lines of credit. The reserve for unfunded loan commitments is an estimate of the losses inherent in off-balance sheet loan commitments to borrowers that are experiencing financial difficulties at the balance sheet date. It is calculated by multiplying an estimated loss factor by an estimated probability of funding, and then by the period-end amounts for unfunded commitments. The reserve for unfunded loan commitments is included as part of accounts payable and other liabilities in the consolidated statements of financial conditi on and any changes to the reserve is included as part of other non-interest expenses in the consolidated statements of income . During the second quarter of 2018, the Corporation implemented certain enhancements to the methodology for the calculation of th e allowance for commercial loans, which include, among others, a revised procedure whereby historical loss rates for each commercial loan regulatory-based credit risk category ( i.e. , pass, special mention, substandard, and doubtful) are now calculated usin g the historical charge-offs and portfolio balances over their average loss emergence period (the “raw loss rate”) for each credit risk classification. However, when not enough loss experience is observed in a particular risk-rated category and the calcula tion results in a loss rate for such risk-rated category that is lower than the loss rate of a less severe risk-rated category, the Corporation now uses the loss rate of such less severe category. As a result of these revisions, the Corporation’s metho d for determining the allowance for loan losses differs from the method that it used as of March 31, 2018, which was to allocate historical losses and portfolio balances of special mention loans to pass or substandard categories based on the historical pro portion of loans in this risk category that ultimately cured or became uncollectible, and the method that it used as of December 31, 2017, which was to use blended loss rates for commercial loans risk-rated special mention, substandard, and doubtful. In addition, during the second quarter of 2018, the Corporation implemented refinements to the measurement of qualitative factors in the estimation process of the allowance for loan losses for commercial and consumer loans, primarily consisting of the incorporation of a basis point adjustment derived from the difference between the average raw loss rate and the highest loss rates observed during a look-back period that management determined was appropriate to use for each region to identify any relevant effect during an economic cycle. Although the net effect of these refinements was immaterial to the total provision expense, on a portfolio basis, these enhancements resulted in a $ 1.6 million decrease in the provision for commercial and construction loa ns, offset by a $ 1.6 million increase in the provision for consumer loans in the second quarter of 2018. Hurricane-Related Qualitative Allowance for Loan and Lease Losses As described in Note 2 – Effects of Natural Disasters, two strong hurricanes affect ed the Corporation’s service areas during September 2017. These hurricanes caused widespread property damage, flooding, power outages, and water and communication service interruptions, and severely disrupted normal economic activity in the affected areas . During the third quarter of 2017, the Corporation recorded a $ 66.5 million charge to the provision related to the establishment of qualitative reserves associated with the effects of Hurricanes Irma and Maria. Models were developed based on a regressio n modeling approach in which relationships between portfolio-level loss rates and key economic indicators were derived based on historical behavior. Accordingly, the qualitative reserves were initially determined based on the estimated effect that the hur ricanes could have on employment levels and economic activity in the Corporation’s service areas, and the time that it could take for the affected regions to return to a more normalized operating environment. For large commercial and construction loan rel ationships, loan officers performed individual reviews of the effect of the hurricanes on these borrowers’ sources of repayments. These large relationships, that represented 80% of the outstanding balance of the Corporation’s commercial and construction l oan portfolio, were analyzed and divided into three hurricane-affected categories ( i.e. , Low, Medium and High). This stratification was used to stress the general reserve loss factors applicable to these loans to reflect higher default probabilities than those reflected in the historical data . During 2018, the Corporation performed additional procedures to evaluate the adequacy of the qualitative reserve, including the consideration of updated payment patterns and probability of default credit risk analyses applied to consumer loan borrowers subject to payment deferral programs that expired early in 2018. For the determination of the hurricane-related qualitative reserve for residential mortgage loans as of December 31, 2018, the Corporation stressed the loss factors derived from its base methodology by incorporating assumptions of further deterioration in the housing price index and higher loan modification levels . Although the foreclosure moratoriums extended by the FHA to hurricane-affected individ uals ended on September 15, 2018, there are likely to be additional delays in foreclosure actions due to court related backlogs. For the determination of the hurricane-related qualitative reserve for commercial and construction loans not individually revie wed as of December 31, 2018, the Corporation segregated the portfolio based on delinquency levels and stressed the general reserve loss factors applicable to 30-89 days past due loans to reflect higher default probabilities. As of December 31, 2018, the hu rricane-related qualitative reserve was $ 19.2 million (2017 - $ 55.6 million), composed of $ 17.2 million for Puerto Rico (2017 - $ 50.2 million) and $ 2.0 million for the Virgin Islands (2017 - $ 5.4 million). On a portfolio basis, the hurricane-related quali tative reserve as of December 31, 2018 and 2017 was composed of: (i) $ 8.8 million for residential mortgage loans (2017 - $ 9.2 million); (ii) $ 3.4 million for commercial and industrial loans (2017 - $ 13.1 million); (iii) $ 3.8 million for commercial mortgage loans (2017 - $ 7.5 million); (iv) $ 0 for construction loans (2017 - $ 0.7 million); and (v) $ 3.2 million for consumer loans (2017 - $ 25.0 million). Refer to Note 1 – Nature of Business and Summary of Significant Accounting Policies , for additional informat ion about the Corporation’s approach to estimating the hurricane-related qualitative reserve. Relationship officers have continued to closely monitor the performance of hurricane-affected commercial loan customers during 2018. Information provided by these commercial loan officers, including information derived from regularly scheduled annual reviews, and statistics on the performance of consumer and residential credits were factored into the determination of the allowance for loan and lease losses as of December 31, 2018. Although the identification and evaluation of hurricane-affected credits has been completed, management’s assessment of the hurricanes’ effect is still subject to uncertainties, both those specific to some individual customers, such as the resolution of insurance claims, and those applicable to the overall economic prospects of the hurricane-affected areas as a whole. During 2018, the Corporation recorded a net loan loss reserve release of $ 16.9 million in connection with revised est imates associated with the effects of the hurricanes. In addition to the above-mentioned updated assessments of financial performance and repayment prospects of certain individually-assessed commercial credits and updated payment patterns and probability of default credit risk analyses applied to consumer borrowers that were subject to payment deferral programs, the reserve releases in 2018 reflect the effect of payments received during 2018 that reduced the balance of the consumer and residential mortgage loan portfolios outstanding o n the dates of the hurricanes. The individual review of large commercial loans also resulted in downgrades in the credit risk classification of certain loans and their hurricane-related qualitative reserves of approximately $ 5 .7 million were transferred to the general reserve and the reserve for such loans are now determined following the methodology applicable to criticized and adversely classified loans, as appropriate. In addition, approximately $ 10.9 million of the consumer loan charge-offs recorded in 2018 were taken against previously-established hurricane-related qualitative reserves associated with Hurricanes Irma and Maria. As of December 31, 2018, the hurricane-related qualitative allowance amounted to $ 19.2 million ( compared to $ 55.6 million as of December 31. 2017). With the ongoing collection of information on individual commercial customers and statistics on the consumer and residential mortgage loans portfolios, the loss estimate will be revised as needed.

The Corporation identified impairment to several of its facilities and equipment in the areas affected by Hurricanes Irma and Maria. Losses related to the damaged facilities and equipment were charged against earnings in 2018 and 2017, and included as a component of “Other non-interest income” in the consolidated statements of income. The losses were determined with information available as to carrying amounts of impaired assets and the extent of the damage sustained. Management identified asset impairm ents of approximately $ 1.3 million and $ 0.6 million as of December 31, 2018 and 2017, respectively. The Corporation maintains insurance policies for casualty losses that provide for replacement value coverage. During 2018, the Corporation received insuran ce proceeds of $ 2.0 million related to losses incurred at some facilities. The insurance proceeds were recorded against i mpairment losses . Insurance recoveries in excess of losses measured, amounting to $ 0.5 million for 2018, were recognized as a gain from insurance proceeds and also reported as part of “Other non-interest income” in the consolidated statement of income.

GOODWILL AND OTHER INTANGIBLES [Text Block]	NOTE 14 – GOODWILL AND OTHER INTANGIBLES Goodwill as of December 31, 2018 and 2017 amounted to $ 28.1 million , recognized as part of “Other Assets” in the consolidated statements of financial condition. The Corporation conducted its annual evaluation of goodwill and other intangibles during the fourth quarter of 201 8 . The Corporation’s goodwill is related to the U.S. (Florida) reporting unit. The Corporation bypassed the qualitative assessment in 2018 and proceeded di rectly to perform the first step of the two-step goodwill impairment test. The Step 1 evaluation of goodwill allocated to the Florida reporting unit under both valuation approaches (market and discounted cash flow analysis) indicated that the fair value of the unit was above the carrying amount of its equity book value as of the valuation date (October 1); therefore, the completion of Step 2 was not required. Based on the analyses under both the market and discounted cash flow approaches, the estimated fair value of the reporting unit exceeded the carrying amount of the entity, including goodwill at the evaluation date. Goodwill was not impaired as of December 31, 2018 or 2017, nor was any goodwill written off due to impairment during 2018, 2017, or 2016. I n 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 ($5.7 million as of December 31, 2018 and $8.0 million as of December 31, 2017), which is being amortized over the remaining estimated life of 2.9 years on an accelerated basis based on the estimated attrition rate of the purchased credit card accounts, which reflects the pattern in which the economic benefits of the intangible asset are consumed. These benefits are consumed as the revenue stream generated by the cardholder relationship is realized. The core deposit intangible of $4.3 million (2017 - $5.5 million) primarily consists of the core deposit acquired in the February 2015 Doral Bank transaction . In the first quarter of 2016, FirstBank Insurance Agency acquired certain insurance customer ac counts and related customer records and recognized an insurance customer relationship intangible of $ 1.1 million ($0.6 million as of December 31, 2018 and $0.8 million as of December 31. 2017), which is being amortized over the remaining estimated life of 4.0 years on a straight-line basis. 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 December 31, 2018 2017 (Dollars in thousands) Core deposit intangible: Gross amount $ 51,664 $ 51,664 Accumulated amortization (1) (47,329) (46,186) Net carrying amount $ 4,335 $ 5,478 Remaining amortization period 6.0 years 7.0 years Purchased credit card relationship intangible: Gross amount $ 24,465 $ 24,465 Accumulated amortization (2) (18,763) (16,465) Net carrying amount $ 5,702 $ 8,000 Remaining amortization period 2.9 years 3.9 years Insurance customer relationship intangible: Gross amount $ 1,067 $ 1,067 Accumulated amortization (3) (445) (292) Net carrying amount $ 622 $ 775 Remaining amortization period 4.0 years 5.0 years (1) For the years ended December 31, 2018, 2017 and 2016, the amortization expense of core deposit intangibles amounted to $1.1 million, $1.7 million and $2.0 million, respectively. (2) For the years ended December 31, 2018, 2017 and 2016, the amortization expense of the purchased credit card relationship intangible amounted to $2.3 million, $2.5 million and $2.8 million, respectively.

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 eva luates if 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 typic ally 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 throug h these transactions ar e guaranteed by the issuer and, under seller/servicer agreements , the Corporation is required to service the loans in accordance with the issuers’ servicing guidelines and standards. As of December 31, 2018 , the Corporation serv iced loans securitized through GNMA with a principal balance of $ 1.7 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 variab le - rate trust-preferred securities. 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 trust-preferred securities. 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 a ggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. The debentures are presented in the Corporation’s consolidated statement of financial condition as Other Borrowings, net of related issuance costs. The variable - rate trust-preferred securities 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; h owever, 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 trust-preferred securities). During the first quarter of 201 8, the Corporation completed the repurchase of $ 23.8 million of trust-preferred securities of the FBP Statutory Trust I that were auctioned in a public sale at which the Corporation was invited to participate. The Corporation’s winning bid equated to 90 % o f the $ 23.8 million par value. The 10 % discount resulted in a gain of approximately $ 2.3 million. In addition, d uring the third quarter of 2017, the Corporation completed the repurchase of $ 7.3 million of trust - preferred securities of the FBP Statutory Tru st I that were offered to the Corporation by an investment banking firm. The Corporation’s purchase price equated to 81 % of the $ 7.3 million par value. The 19 % discount, plus accrued interest, resulted in a gain of approximately $ 1.4 million . In a separate transaction, during the first quarter of 2016, the Corporation completed the repurchase of $ 10 million of trust-preferred securities of the FBP Statutory Trust II that were auctioned in a public sale at which the Corporation was invited to participate. Th e Corporation’s winning bid equated to 70 % of the $ 10 million par value. The 30 % discount, plus accrued interest, resulted in a gain of approximately $ 4.2 million. These gains are reflected in the statement of income as a “Gain on early extinguishment of d ebt”. The Collins Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act eliminated certain trust-preferred securities 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. During the second quarter of 2016, the Corporation , having received ap proval from the Federal Reserve, paid $ 31.2 million for all of the accru ed but deferred interest payments plus the interest for the second quarter of 2016 on the Corporation’s subordinated debentures associated with its trust - preferred securities. Subsequently, the Corporation has received quarterly approvals that have enabled it to make scheduled quarterly interest pa yments. As of December 31, 2018 , the Corporation was current on all interest payments due on its subordinated debt. I n October 2017, the New York FED terminated the formal written agreement (the “Written Agreement”) entered into on June 3, 2010 by the Corporation and the Reserve Bank. However, t he Corporation has agreed with its regulators to continue to obtain approval before paying dividends, receiving dividends from the Bank, making payment s on subordin ated debt or trust- preferred securities, incurring or guaranteeing debt or purchasing or r edeeming any corporate stock. The Corporation has received approval to make the subordinated debentures ’ quarterly payment through December 2019 , subject to condition s established in the agreement with regulators . Grantor Trusts 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 (the “Grantor Trusts”) . The seller initially provided the servicing for a fee, which is senior to the obligations to pay trust certificate holders. The seller then entered into a sales agreement through which it sold and issued t he trust certificates in favor of the Corporation’s banking subsidiary. Currently, the Bank is the sole owner of the trust certificates; 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. The trust certificates 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 i nterest to the Bank . I nterest income is shared to a certain extent with the FDIC, which has an interest only strip (“IO”) tied to the cash flo ws 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 beca me the owner of the IO upon its intervention of the seller, a failed financial institution. No recourse agreement exists , and the Bank, as a sole holder of the certificates, absorbs all risk s from losses on non- accruing loans and repossessed collateral . As of December 31, 2018 , the amortized cost and fair value of the Grantor Trusts amounted to $ 19.3 mi llion and $ 13.9 million, respectively, with a weighted - average yield of 4.89 % , which is included as part of the Corporation’s available-for-sale investment securities portfolio . Investment in unconsolidated entity On February 16, 2011, FirstBank sold an asset portfolio consisting of performing and nonaccrual construction, commercial mortgage and commercial and industrial loans with an aggregate book value of $ 269.3 million to CPG/GS, an entity organized under the laws of the Commonwealth of Puerto Rico an d majority owned by PRLP Ventures LLC (“PRLP”), a company created by Goldman, Sachs & Co. and Caribbean Property Group. In connection with the sale, the Corporation received $ 88.5 million in cash and a 35 % interest in CPG/GS, and made a loan in the amount of $ 136.1 million representing seller financing provided by FirstBank. The loan matured in February 2018 and was refinanced and consolidated with other outstanding loans of CPG/GS in the second quarter of 2018. As of December 31, 2018, the carrying amount of the refinanced loan was $ 6.2 million, which was included in the Corporation’s commercial mortgage loans held for investment portfolio. This loan has a three-year maturity, bears a fixed-interest rate, and is primarily secured by income-producing real e state properties and certain residential units. 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. Cash proceeds receive d by CPG/GS have been first used to cover operating expenses and debt service payments, including those related to the refinanced loan described above, which must be substantially repaid before proceeds can be used for other purposes, including the return of capital to both PRLP and FirstBank. 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 Fir stBank’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 gui dance 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 per formance 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 mortgage-backed securities. 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. The changes in servicing assets are shown below: Year Ended December 31, 2018 2017 2016 (In thousands) Balance at beginning of year $ 25,255 $ 26,244 $ 24,282 Capitalization of servicing assets 3,864 3,318 5,260 Amortization (2,895) (3,091) (3,229) Temporary impairment recoveries (charges), net 1,289 (1,611) (325) Other (1) (85) 395 256 Balance at end of year $ 27,428 $ 25,255 $ 26,244 (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: Year ended December 31, 2018 2017 2016 (In thousands) Balance at beginning of year $ 1,451 $ 461 $ 136 Temporary impairment charges 123 1,611 466 OTTI of servicing assets (132) (621) - Recoveries (1,412) - (141) Balance at end of year $ 30 $ 1,451 $ 461 The components of net servicing income are shown below: Year ended December 31, 2018 2017 2016 (In thousands) Servicing fees $ 8,704 $ 7,630 $ 7,606 Late charges and prepayment penalties 510 405 674 Adjustment for loans repurchased (85) 395 256 Other (8) (35) (1) Servicing income, gross 9,121 8,395 8,535 Amortization and impairment of servicing assets (1,606) (4,702) (3,554) Servicing income, net $ 7,515 $ 3,693 $ 4,981 The Corporation’s servicing assets are subject to prepayment and interest rate risks. Key economic assumptions used in determining the fair value at the time of sale of the related mortgages ranged as follows: Maximum Minimum 2018: Constant prepayment rate: Government-guaranteed mortgage loans 6.0 % 5.6 % Conventional conforming mortgage loans 6.5 % 6.2 % Conventional non-conforming mortgage loans 10.3 % 9.1 % Discount rate: Government-guaranteed mortgage loans 12.0 % 12.0 % Conventional conforming mortgage loans 10.0 % 10.0 % Conventional non-conforming mortgage loans 14.3 % 14.3 % 2017: Constant prepayment rate: Government-guaranteed mortgage loans 6.2 % 6.0 % Conventional conforming mortgage loans 6.7 % 6.3 % Conventional non-conforming mortgage loans 9.5 % 9.1 % Discount rate: Government-guaranteed mortgage loans 12.0 % 12.0 % Conventional conforming mortgage loans 10.0 % 10.0 % Conventional non-conforming mortgage loans 14.3 % 14.3 % 2016: Constant prepayment rate: Government-guaranteed mortgage loans 7.6 % 5.9 % Conventional conforming mortgage loans 8.0 % 6.3 % Conventional non-conforming mortgage loans 14.1 % 9.3 % Discount rate: Government-guaranteed mortgage loans 12.0 % 11.5 % Conventional conforming mortgage loans 10.0 % 9.5 % Conventional non-conforming mortgage loans 14.3 % 13.8 % 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 December 31, 2018 were as follows: (Dollars in thousands) Carrying amount of servicing assets $ 27,428 Fair value $ 31,738 Weighted-average expected life (in years) 8.45 Constant prepayment rate (weighted-average annual rate) 6.26 % Decrease in fair value due to 10% adverse change $ 747 Decrease in fair value due to 20% adverse change $ 1,462 Discount rate (weighted-average annual rate) 11.25 % Decrease in fair value due to 10% adverse change $ 1,528 Decrease in fair value due to 20% adverse change $ 2,930 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 resul t in changes in another (for example, increases in market interest rates may result in lower prepayments), which may magnify or counteract the sensitivities .

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE [Text Block]	NOTE 21 – EARNINGS PER COMMON SHARE The calculation of earnings per common share for the years ended December 31, 2018, 2017, and 2016 are as follows: Year Ended December 31, 2018 2017 2016 (In thousands, except per share information) Net income $ 201,608 $ 66,956 $ 93,229 Less: Preferred stock dividends (2,676) (2,676) (223) Net income attributable to common stockholders $ 198,932 $ 64,280 $ 93,006 Weighted-Average Shares: Average common shares outstanding 215,709 213,963 212,818 Average potential dilutive common shares 968 2,155 2,976 Average common shares outstanding - assuming dilution 216,677 216,118 215,794 Earnings per common share: Basic $ 0.92 $ 0.30 $ 0.44 Diluted $ 0.92 $ 0.30 $ 0.43 ____________ 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 p referred stock dividends, including any dividends declared , 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 unve sted share s 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, performance units that do not contain non-forfe itable dividend rights if the performance condition is met as of the end of the reporting period, warrants outstanding during the period and common stock issued under the assumed exercise of stock options using the treasury stock method . This method assume s 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 differenc e between the number s 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 and performance units th at do not contain non-forfeitable dividend rights , stock options, and warrants 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. Stock options not included in the computation of outstanding shares because the y were antidilutive amounted to 34,989 as of December 31, 2016. There were no stock options outstanding as of December 31, 2018 and 2017. On May 17, 2018, the U.S. Treasury exercised its warrant to purchase 1,285,899 shares of the Corporation’s common stock on cashless basis, resulting in the issuance of 730,571 shares of common stock.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION [Text Block]	NOTE 22 – 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 19 86, 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 December 31, 201 8 , 6,897,855 authorized shares of common stock wer e 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 es tablish 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, su bject 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, restricted stock participant s may exercise full voting rights. The restricted stock granted under the Omnibus Plan is typically subject to a vesting period. During 2018, the Corporation awarded to its independent directors 65,447 shares of restricted stock that are subject to a one-y ear vesting period. In addition, during 2018, the Corporation awarded 342,439 shares of restricted stock to employees; fifty percent ( 50 %) of those shares vest in two years from the grant date and the remaining ( 50 %) vest in three years from the grant date . Included in those 342,439 shares of restricted stock were 20,447 shares granted to retirement-eligible employees at the grant date. The total expense determined for the restricted stock awarded to retirement-eligible employees was charged against earnings at the grant date. The fair value of the shares of restricted stock granted in 2018 was based on the market price of the Corporation’s outstanding common stock on the date of the grant. The following table summarizes the restricted stock activity in 2018 under the Omnibus Plan: 2018 Number of Weighted- shares of Average restricted Grant Date stock Fair Value Non-vested shares at beginning of year 1,816,968 $ 2.76 Granted 407,886 6.71 Forfeited (16,000) 4.31 Vested (1,244,744) 2.47 Non-vested shares at end of year 964,110 $ 4.79 For the years ended December 31, 201 8 , 201 7 and 201 6 , the Corporation recognized $ 3.4 million, $ 4.0 million and $ 3 . 9 million, respectively, of stock-based compensation expense related to restricted stock awards. As of December 31, 201 8 , there was $ 2.2 million of total unrecognized compensation cost related to non - vested shares of restricted stock. The weighted average p eriod over which the Corporation expects to recognize such cost is 1.3 years . During 2017, the Corporation awarded to its independent directors 148,424 shares of restricted stock subject to a one-year vesting period. In addition, during 2017, the Corpora tion awarded 951,332 shares of restricted stock to employees subject to a vesting period of two years. Included in those 951,332 shares of restricted stock were 838,332 shares granted in the first quarter of 2017 to certain senior officers consistent with the requirements of the Troubled Asset Relief Program (“TARP”) Interim Final Rule. On May 10, 2017, the United States Department of the Treasury (the “U.S. Treasury”) announced that it had sold all of its remaining 10,291,553 shares of the Corporation’s co mmon stock. As a result of the sale by U.S. Treasury, the Corporation ceased being subject to the compensation-related restrictions under TARP, which substantially limited the Corporation’s ability to award short-term and long-term incentives to the Corpor ation’s executives, and the Corporation’s senior officers are no longer subject to the transferability restrictions on their shares of restricted stock. However, since the U.S. Treasury did not recover the full amount of its original investment under TARP, the senior officers forfeited 2,370,571 , or 50 %, of their outstanding shares of restricted stock, resulting in a reduction in the number of common shares outstanding. The Corporation accounted for the restricted stock that it granted in 2017 prior to the U.S. Treasury’s sale of its shares at a discount from the market price of the Corporation’s outstanding common stock on the date of the grant. For the 838,332 shares of restricted stock granted under the TARP requirements, the market price was discounted a ssuming that 50 % of the shares of restricted stock would become freely transferable and the remaining 50 % would be forfeited , resulting in a fair value of $ 2.71 for each share of restricted stock granted under TARP requirements. Stock-based compensati on 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 compensa tion, as the effect of adjusting the rate for all expense amortization is recognized 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 t he 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. The estimated forfeiture rate did not change as a result of the restricted shares forfeited in connection with the aforementioned U.S. Treasury’s sale of the Corporat ion’s common stock. Performance Units Under the Omnibus Plan, the Corporation may award performance units to Omnibus Plan participants. During 2018, the Corporation granted 304,408 units to executives, with each unit representing the value of one share of the Corporation’s common stock. The performance units granted are for the performance period beginning January 1, 2018 and ending on December 31, 2020 and are subject to a three-year requisite service period. These awards do not contain non-forfeitable rights to dividend equivalent amounts and can only be settled in shares of the Corporation’s common stock. Included in those 304,408 performance units were 29,171 units granted to retirement-eligible executives at the grant date. The performance units will vest based on the achievement of a p re-established tangible book value per share target as of December 31, 2020. All of the performance units will vest if performance is at the pre-established performance target level or above. However, the participants may vest on 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. The fair value of the performance units awarded during 2018 was based on the market price of the Corporation’s outstanding common stock on the date of the grant. For the year ended December 31, 2018, the Corp oration recognized $ 0.6 million of stock-based compensation related to performance unit s. As of December 31, 2018, there was $ 1.3 million of total unrecognized compensation cost related to unvested performance units that the Corporation expects to recognize over the three-year requisite service period. The total expense determined for the pe rformance units awarded to retirement-eligible executives was charged against earnings at the grant date. The total amount of compensation expense recognized reflects management’s assessment of the probability that the pre-established performance goal will be achieved. A cumulative adjustment to compensation expense is recognized in the current period to reflect any changes in the probability of achievement of the performance goals. Salary stock Also, effective April 1, 2013, the Corporation’s Board of Directors determined to increase the salary amounts paid to certain executive officers , primarily by paying the increased salary amounts in the form of shares o f the Corporation’s common stock issue d under the Omnibus Plan, instead of cash. During 201 8 , the Corporation issued 268,709 shares of common stock ( as compared to 582,193 shares during 2017 ) with a weighted-average market value of $ 6.51 ( as compared to a weighted average market value of $ 5.64 during 2017 ) as salary stock compensation. This resulted in a compensation expense of $ 1.7 million recorded in 201 8 ( as compared to $ 3 . 3 million during 2017 ). Effective July 1, 2018, the payment of additional salary amounts in the form of stock was elimin ated in accordance with the previously disclosed revised executive compensation program. For 2018, the Corporation withheld 96,377 shares (2017 – 195,789 shares) from the common stock paid to certain senior officers as additional compensation and 337,689 shares of restricted stock that vested during 201 8 (201 7 - 243,102 shares) to cover employees’ 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 the officer was entitled. In the consolidated financial statements, the Corporation treats shares withheld for tax purposes as common stock repurchases .

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. In December 2016, f or the first time since July 2009, the Corporati on paid dividends on its non-cumulative perpetual monthly income preferred stock, after receiving regulatory approval. Since then, the Corporation has continued to pay monthly dividend payments on the non-cumulative perpetual monthly income preferred stock . The Corporation has received regulatory approval to pay the monthly dividends on the Corporation’s Series A through E Preferred Stock through December 2019, subject to conditions established in the agreement with regulators. The Corporation intends to re quest approval in future periods to continue monthly dividend payments on the non-cumulative perpetual monthly income preferred stock. On October 3, 2017, the Federal Reserve terminated the Written Agreement entered into on June 3, 2010 by the Corporation and the Federal Reserve. However, the Corporation has agreed with its regulators to continue to obtain approval before paying dividends, receiving dividends from the Bank, making payments on subordinated debt or trust preferred securities, incurring or gu aranteeing debt or purchasing or redeeming any corporate stock. T reasury stock During 201 8 and 201 7 , the Corporation withheld an aggregate of 434,066 shares and 438,891 shares, respectively, of the common stock paid to certain senior officers as additional compensation and restricted stock that vested during 201 8 and 201 7 to cover employees’ payroll and income tax withholding li abilities; these shares are held as treasur y s tock . As of December 31, 201 8 and 201 7 , the Corporation had 4,554,369 and 4,104,303 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 the retained earnings account 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 expendit ures 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 re duction 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 reserv e to an amount of at least 20 % of the original capital contributed. During 2018 and 201 7, $ 20.5 million and $ 7.3 million, respectively, were transferre d to the legal surplus reserve. FirstBank’s legal surplus reserve, included as part of retained earnings in the Corporation’s consolidated statement of financial condition, amounted to $ 80.2 million and $ 59.7 million as of December 31, 201 8 and 201 7, respectively .

Income Tax Disclosure [Abstract]
INCOME TAXES [Text Block]	NOTE 26 – 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 connecte d 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 generally not entitled to file consolidated tax returns and, thus, the Corporation is generally not entitled to uti lize 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 carryforward 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 allows an entity organized as a limited liability company to elect to become a non-taxable “pass-through” entity and utilize losses to offset income from other “pass-through” entities , subject to certain limitations, with the remaining net income passing-through to its partner entities. The 2011 PR Code also 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. On March 1, 2017, the Corporation completed the applicable regulatory filings to change the tax status of its subsidiary, First Federal Finance, from a taxable corporation to a non-taxable “pass-through” entity. This election has allowed the Corporation to realize tax benefits of its deferred tax assets associated with pass-through ordinary net operating losses available at the banking subsidiary, FirstBank, which were subject to a full valuation allowance as of December 31, 2016, against now pass-through ordinary income from this profitable subsidiary. On March 1, 2017, the Corporation also completed the applicable regulatory filings to change the tax status of its subsidiary, F irstBank Insurance, from a taxable corporation to a non-taxable “pass-through” entity. This election has allowed the Corporation to offset pass-through income earned by FirstBank Insurance with net operating losses available at the Holding Company level. On December 22, 2017, the United States President signed H.R.1, The Tax Cuts and Jobs Acts, effective January 1, 2018, which includes an overhaul of individual, business and international taxes and has affected our branch operations in the U.S. and the USV I. The bill includes measures reducing corporate taxes from 35% to 21%, a repeal of the corporate alternative minimum tax regime, changes to business deductions and NOLs, a 15.5% tax on mandatory repatriation of liquid assets, 10% tax on base erosion payme nts, and a minimum 10.5% tax on inclusion of global intangible low-tax income by U.S. shareholders, among other significant changes. The main provisions affecting our operations in the U.S. and the USVI for the year 2018 include: the change in tax rate to 21%, the limitation to the amount certain financial institutions may deduct for premiums paid to the FDIC, and changes in permanent differences, such as meals and entertainment deductions. Other significant provisions, such as the base erosion and anti-abu se tax, do not affect the Corporation’s U.S. and USVI branch operations since these operations’ receipts do not exceed the annual threshold of U.S. effectively connected gross receipts. On December 10, 2018, the Governor of Puerto Rico signed into Law Ac t 257 (“Act 257”) to amend some of the provisions of the 2011 PR Code, as amended. Act 257 introduces various changes to the current income tax regime in the case of individuals and corporations, and the sales and use taxes that are effective January 1, 2019, including, among others, (i) a reduction in the Puerto Rico corporate tax rate from 39% to 37.5%; (ii) an increase in the net operating and capital losses usage limitation from 80% to 90%; (iii) amendments to the provisions related to “pass-through” entities that provide that corporations that own 50% or more of a partnership will not be able to claim a current or carryover non partnership NOLs deduction against a partnership dis tributable share, adversely impacting the above described tax action taken in 2017 for FirstBank Insurance; and (iv) other limitations on certain deductions such as meals and entertainment deductions. The PROMESA oversight board accepted the required certi fication submitted by the Legislature of Puerto Rico (the “Compliance Certification”) acknowledging that Act 257 is not significantly inconsistent with the Commonwealth’s Fiscal Plan as it applies to Articles 1 through 131 and 164-165 of Act 257 . However, the PROMESA oversight board expressed concerns regarding certain provisions of Act 257, specifically Articles 132 through 163, regarding the video lottery terminals that operate outside casinos in Puerto Rico. It is not yet determined whether Act 257 wi ll be further amended to accommodate any mandate from the PROMESA o versight b oard. The Corporation has maintained an effective tax rate lower than the maximum statutory rate, mainly by investing in government obligations and MBS exempt from U.S. and Puert o 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 gain on sales is exempt from Puerto Rico income taxatio n. 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 ident ified in the IBE Act. An IBE that operates as a unit of a bank pays income taxes at the corporate standard rate to the extent that the IBE’s net income exceeds 20 % of the bank’s total net taxable income. The components of income tax (benefit) expense are summarized below: Year Ended December 31, 2018 2017 2016 (In thousands) Current income tax expense $ 14,073 $ 8,179 $ 13,151 Deferred income tax expense (benefit): Adjustment for enacted changes in tax law 15,402 138 (20) Reversal of deferred tax asset valuation allowance (63,228) (1,792) - Other deferred income tax expense (benefit) 22,783 (11,498) 23,899 Total income tax (benefit) expense $ (10,970) $ (4,973) $ 37,030 The differences between the income tax expense applicable to income before the provision for income taxes and the amount computed by applying the statutory tax rate in Puerto Rico were as follows: Year Ended December 31, 2018 2017 2016 Amount % of Pretax Income Amount % of Pretax Income Amount % of Pretax Income (Dollars in thousands) Computed income tax at statutory rate $ 74,349 39.0 % $ 24,173 39.0 % $ 50,801 39.0 % Federal and state taxes 3,768 2.0 % 2,335 3.8 % - - % Benefit of net exempt income (22,782) (12.0) % (16,596) (26.8) % (14,995) (11.5) % Disallowed NOL carryforward resulting from net exempt income 14,904 7.8 % 5,091 8.2 % 6,396 4.9 % Deferred tax valuation allowance (90,521) (47.5) % (10,037) (16.2) % (5,976) (4.6) % Adjustments in net deferred tax assets due to changes in enacted tax rates 15,402 8.1 % 138 0.2 % (20) - % Change in tax status of subsidiaries - - % (13,161) (21.2) % - - % Share-based compensation windfall (1,595) (0.8) % (40) - % 92 0.1 % Effect of capital losses subject to preferential rates - - % 2,102 3.4 % 727 0.6 % Non deductible expenses and other permanent differences (839) (0.4) % (470) (0.8) % (1,720) (1.2) % Tax return to provision adjustments 4 - % 607 1.0 % 434 0.3 % Other-net (3,660) (1.9) % 885 1.4 % 1,291 1.0 % Total income tax (benefit) expense $ (10,970) (5.7) % $ (4,973) (8.0) % $ 37,030 28.6 % For 2018, the Corporation recorded an income tax benefit of approximately $11.0 million compared to an income tax benefit of $5.0 million for 2017. The income tax benefit for 2018 was driven by a $90.5 million change in the deferred tax asset valuation allowance, primarily attributable to a $63.2 million partial reversal of FirstBank’s deferred tax asset valuation allowance recorded during the fourth quarter of 2018. The income tax benefit for 2017 was mostly attributable to the tax benefit related to hurricane-related charges and to a $ 13.2 million tax benefit resulting from the above discussed change in tax status of certain subsidiaries from taxable corporations to limited liability companies that hav e elected to be treated as partnerships for income tax purposes in Puerto Rico. The Corporation adjusted its Puerto Rico deferred tax assets due to the reduction in the Puerto Rico corporate tax rate as per Act 257. The adjustment resulted in a charge of approximately $9.9 million to income tax expense. As a result of the partial reversal of the deferred tax asset valuation allowance and the remeasurement of deferred tax assets in connection with the enactment of Act 257 , the Corporation’s net de ferred tax assets amounted to $ 319.9 million as of December 31, 2018, net of a valuation allowance of $100.7 million, compared to net deferred tax assets of $294.8 million, net of a valuation allowance of $191.2 million as of December 31, 2017. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their tax bases. Significant components of the Corporation's deferred tax assets and liabilities as of December 31, 2018 and 2017 were as follows: December 31, 2018 2017 (In thousands) Deferred tax asset: Net operating loss carryforward $ 316,059 $ 376,423 Allowance for loan and lease losses 75,010 94,111 Alternative Minimum Tax credits available for carryforward 9,238 6,598 Unrealized loss on OREO valuation 15,405 14,784 Unrealized loss on available-for-sale securities, net 189 - Settlement payment-closing agreement 7,031 7,313 Legal and other reserves 3,293 2,333 Reserve for insurance premium cancellations 610 635 Other 7,526 8,326 Total gross deferred tax assets 434,361 510,523 Deferred tax liabilities: Differences between the assigned values and tax bases of assets and liabilities recognized in purchase business combinations 4,192 5,143 Servicing assets 9,143 8,625 Unrealized gain on available-for-sale securities, net - 1,306 Other 514 9,457 Total gross deferred tax liabilities 13,849 24,531 Valuation allowance (100,661) (191,183) Net deferred tax asset $ 319,851 $ 294,809 Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against their deferred tax asset based on an assessment of the amount of the deferred tax asset that is “more likely than not” to be realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized. Management assesses the valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, and tax planning strategies. In estimating taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, judicial, and regulatory guidance . After completion of the deferred tax asset valuation allowance analysis for the fourth quarter of 2018, management concluded that, as of December 31, 2018, it is more likely than not that FirstBank, the banking subsidiary, will generate sufficient taxable income within the applicable NOL carry-forward periods to realize $ 220.5 million of its deferred tax assets related to NOLs and, therefore, reversed $ 63.2 million of the valuation allowance. The decision to partially reverse the valuation allowance was r eached after weighting all of the evidence and determining that the positive evidence out weighted the negative evidence. The positive evidence considered by management in arriving at its conclusion to reverse part of the deferred tax asset valuation allow ance includes factors such as : FirstBank’s three-year cumulative income position ; the continued profitability following the hurricane events in 2017; and forecasts of future profitability, under several potential scenarios, that support significant utiliza tion of NOLs prior to their expiration ranging between the years 2021 through 2024. The negative evidence considered by management includes: uncertainties around the state of the Puerto Rico economy, including the effect of hurricane recovery funds togethe r with Puerto Rico government debt renegotiati on efforts and the ultimate sustainability of the approved Fiscal Plan; and consideration of the Corporation’s still elevated levels of non-performing assets. Management’s estimate of future taxable income is based on internal projections that consider historical performance, multiple internal scenarios and assumptions, as well as external data that management believes is reasonable. If events are identified that affect the Corporation’s ability to utilize its deferred tax assets, the analysis will be updated to determine if any adjustments to the valuation allowance are required. If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, the remaining valuation allowance may need to be increased. Such an increase could have a material adverse effect on the Corporation’s financial condition and results of operations. Conversely, a higher than projected proportion of taxable inco me to exempt income could lead to a higher usage of available NOLs and a lower amount of disallowed NOLs from projected levels of tax-exempt income, per the 2011 PR code, which in turn could result in further releases to the deferred tax valuation allowanc e; any such decreases could have a material positive effect on the Corporation’s financial condition and results of operations. As of December 31, 2018, approximately $ 10 4 million of the deferred tax assets of the Corporation are attributable to temporary differences or tax credit carry-forwards that have no expiration date, compared to $ 125.6 million in 2017. The valuation allowance attributable to FirstBank’s deferred tax assets of $ 68.1 million as of December 31, 2018 is related to the estimated NOL dis allowance attributable to projected levels of tax-exempt income; NOLs attributable to the Virgin Islands jurisdiction; and capital losses. The remaining balance of $ 32.6 million of the deferred tax asset valuation allowance non-attributable to FirstBank is mainly related to NOLs and capital losses at the Holding Company and the Bank’s subsidiary First Management of Puerto Rico. The Corporation will continue to provide a valuation allowance against its deferred tax assets in each applicable tax jurisdiction until the need for a valuation allowance is eliminated. The need for a valuation allowance is eliminated when the Corporation determines that it is more likely than not the deferred tax assets will be realized. The ability to recognize the remaining defer red tax assets that continue to be subject to a valuation allowance will be evaluated on a quarterly basis to determine if there are any significant events that would affect the ability to utilize these deferred tax assets. The Corporation has U.S. and US VI sourced NOL carryforwards. Section 382 of the U.S. Internal Revenue Code (the “Section 382”) limits the ability to utilize U.S. and USVI NOLs for income tax purposes in such jurisdictions following an event that is considered to be an ownership change. Generally, an “ownership change” occurs when certain shareholders increase their aggregate ownership by more than 50 percentage points over their lowest ownership percentage over a three-year testing period. Upon the occurrence of a Section 382 ownership change, the use of NOLs attributable to the period prior to the ownership change is subject to limitations and only a portion of the U.S. and USVI NOLs may be used by the Corporation to offset its annual U.S. and USVI taxable income, if any. During 2017, the Corporation completed a formal ownership change analysis within the meaning of Section 382 covering a comprehensive period, and concluded that an ownership change occurred during such period. The ownership change and resulting Section 382 limitation d id not cause a U.S. or USVI income tax liability or material income tax expense related to periods prior to 2017 since the Corporation had sufficient post-ownership change NOLs in those jurisdictions to offset taxable income. The Section 382 limitation re sulted 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 2018 and 2017 year, and as a result of the Section 382 limitation, the Corporation incurred an income tax expense of approximately $ 3.8 million and $ 2.3 million, respectively, related to its U.S. oper ations. The limitation did not impact the USVI operations for the years 2018 and 2017. As of December 31, 2018, the Corporation did not have UTBs recorded on its books. The Corporation classifies all interest and penalties, if any, related to tax uncert ainties 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 year s after a tax return is due or filed, whichever is later, for each. 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 f or 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 subsequen t to 2014 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2013 remain open to examination.

FAIR VALUE

FAIR VALUE	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE [Text Block]	NOTE 29 – 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 mea sure fair value are observable or unobservable. 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 involvin g 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 tra ded 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 obs ervable 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 princ ipally 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 asset s 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 estimation. Financial Instruments Record ed at Fair Value on a Recurring Basis Investment securities available for sale and marketable e quity 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 Treasury notes, non-callable U.S. Agency 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) that are based on observable market parameters, including benchmark yields, reported trades, quotes from brokers or dealers, issu er 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 co unterparties, when appropriate. On interest caps, only the seller’s credit risk is considered. The caps were valued using a discounted cash flow approach based on the related LIBOR and swap rate for each cash flow. A credit spread is considered for those derivative instruments that are not secured. The cumulative mark-to-market effect of credit risk in the valuation of derivative instru ments in 201 8 , 201 7 and 201 6 was immaterial.

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 v alue of the instruments. Meaningful and possible shifts of each input were modeled 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 that are g uaranteed by the Puerto Rico Housing Finance Authority . A significant increase (decrease) in the assumed rate would lead to a hig her (lower) fair v alue 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 mark et for them. Due to the guarantee of the Puerto Rico Housing Finance Authority and other applicable contractual safeguards, no additional credit spread is applied for debt service default . The table below summarizes changes in unrealized gains and losses recorded in earnings for the years ended December 31, 2018, 2017, and 2016 for Level 3 assets and liabilities that are still held at the end of each year: Changes in Unrealized Losses (Year Ended December 31, 2018) Changes in Unrealized Losses (Year Ended December 31, 2017) Changes in Unrealized Losses (Year Ended December 31, 2016) Level 3 Instruments Only Securities Available for Sale Securities Available for Sale Securities Available for Sale (In thousands) Changes in unrealized losses relating to assets still held at reporting date: Net impairment losses on available-for-sale investment securities (credit component) $ (50) $ - $ (387) 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 in dividual assets ( e.g ., goodwill and loans). As of December 31, 201 8 , impairment or valuation adjustments were recorded for assets recognized at fair value on a non-recurring basis as shown in the following table: Carrying value as of December 31, 2018 (Losses) recorded for the Year Ended December 31, 2018 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 365,726 $ (29,799) OREO (2) - - 131,402 (11,499) Loans held for sale (3) - - 16,111 (10,102) (1) Consists mainly of impaired commercial and construction loans. The impairments were generally measured based on the fair value of the collateral. The fair values were derived from external appraisals that took into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the collateral ( e.g ., absorption rates), which are not market observable. (2) The fair values were derived from appraisals that took into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the properties ( e.g ., absorption rates and net operating income of income producing properties), which are not market observable. Losses were related to market valuation adjustments after the transfer of the loans to the OREO portfolio. (3) Nonaccrual commercial and construction loans transferred to held for sale in 2018 and still in inventory at year end. The value of these loans was primarily derived from broker price opinions that the Corporation considered. As of December 31, 2017, impairment or valuation adjustments were recorded for assets recognized at fair value on a non-recurring basis as shown in the following table: Carrying value as of December 31, 2017 (Losses) recorded for the Year Ended December 31, 2017 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 410,428 $ (39,493) OREO (2) - - 147,940 (8,511) Mortgage servicing rights (3) - - 25,255 (1,611) (1) Consists mainly of impaired commercial and construction loans.

(2) The fair values were derived from appraisals that took into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the properties ( e.g ., absorption rates and net operating income of income producing properties), which are not market observable. Losses were related to market valuation adjustments after the transfer of the loans to the OREO portfolio. (3) Fair value adjustments to mortgage servicing rights were mainly due to assumptions associated with mortgage prepayment rates. The Corporation carries its mortgage servicing rights at the lower of cost or market, measured at fair value on a non-recurring basis. Assumptions for the value of mortgage servicing rights include: Prepayment rate 6.30%, Discount rate 11.23%. As of December 31, 2016, impairment or valuation adjustments were recorded for assets recognized at fair value on a nonrecurring basis as shown in the following table: Carrying value as of December 31, 2016 (Losses) recorded for the Year Ended December 31, 2016 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 442,081 $ (49,884) OREO (2) - - 137,681 (7,873) Mortgage servicing rights (3) - - 26,244 (325) (1) Consists mainly of impaired commercial and construction loans.

(3) Fair value adjustments to the mortgage servicing rights were mainly due to assumptions associated with mortgage prepayments rates. The Corporation carries its mortgage servicing rights at the lower of cost or market, measured at fair value on a non-recurring basis. Assumptions for the value of mortgage servicing rights include: Prepayment rate 6.12%, Discount rate 11.19%. Qualitative information regarding the fair value measurements for Level 3 financial instruments as of December 31, 2018 are as follows: December 31, 2018 Method Inputs Loans Income, Market, Comparable Sales, Discounted Cash Flows External appraised values; probability weighting of broker price opinions; management assumptions regarding market trends or other relevant factors OREO Income, Market, Comparable Sales, Discounted Cash Flows External appraised values; probability weighting of broker price opinions; management assumptions regarding market trends or other relevant factors The following is a description of the valuation methodologies used for instruments that are not measured or reported at fair value on a recurring basis or reported at fair value on a non-recurring basis. The estimated fair value was calculated using certain facts and assumptions, which vary depending on the specific financial instrument. Cash and due from banks and money market investments The carrying amounts of cash and due from banks and money market investments are reasonable estimates of their fair value. Money market investments include held-to-maturity securities, which have a contractual maturity of three months or less. The fair value of these securities is based on quoted market prices in active markets that incorporate the risk of nonperf ormance. Investment securities held to maturity Investment securities held to maturity consist of financing arrangements with Puerto Rico municipalities issued in bond form, but underwritten as loans with features that are typically found in commercial loan transactions. These obligations typically are not issued in bearer form, nor are they registered with the Securities and Exchange Commission and are not rated by external credit agencies. The fair value of these financing arrangements was based on a d iscounted cash flow analysis using risk-adjusted discount rates (Level 3). The credit spreads for valuations are based on a similar security that traded in the open market. Other equity securities Equity or other securities that do not have a readily ava ilable fair value are stated at their net realizable value, which management believes is a reasonable proxy for their fair value. This category is principally composed of stock that is owned by the Corporation to comply with FHLB regulatory requirements. T he realizable value of the FHLB stock equals its cost as this stock can be freely redeemed at par. Loans receivable, including loans held for sale The fair value s of loans held for investment and of mortgage loans held for sale w ere estimated using disco unted cash flow analyses, based on interest rates currently being offered for loans with similar terms and credit quality and with adjustments that the Corporation’s management believes a market participant would consider in determining fair value. Loans w ere classified by type, such as commercial, residential mortgage, and automobile. These asset categories were further segmented into fixed-and adjustable-rate categories. Valuations are carried out based on categories and not on a loan-by-loan basis. The fair values of performing fixed-rate and adjustable-rate loans were calculated by discounting expected cash flows through the estimated maturity date. This fair value is not currently an indication of an exit price as that type of assumption could result i n a different fair value estimate. The fair value s of credit card loans w ere estimated using a discounted cash flow method and excludes any value related to a customer account relationship. Other loans with no stated maturity, like credit lines, were value d at book value. Prepayment assumptions were considered for non-residential loans. For residential mortgage loans, prepayment estimates were based on a prepayment model that combined both a historical calibration and current market prepayment expectations. Discount rates were based on the U.S. Treasury and LIBOR/Swap Yield Curves at the date of the analysis, and included appropriate adjustments for expected credit losses and liquidity. For impaired collateral dependent loans, the impairment was primarily m easured based on the fair value of the collateral, which is derived from appraisals that take into consideration prices in observable transactions involving similar assets in similar locations. Deposits The estimated fair value s of demand deposits and savings accounts, which are deposits with no defined maturities, equal the amount payable on demand at the reporting date. The fair values of retail fixed-rate time deposits, with stated maturities, are based on the present value of the future cash flows expected to be paid on the deposits. The cash flows were based on contractual maturities; no early repayments were assumed. Discount rates were based on the LIBOR yield curve. The estimated fair value of total deposits excludes the fair value of core deposit intangibles, which represent the value of the customer relationship. The fair value of total deposits is measured by the value of demand deposits and savings deposits that bear a low or zero rate of interest and do not fluctuate in response to changes in interest rates. The fair value s of brokered CDs, which are included within deposits, are determined using discounted cash flow analyses over the full term s of the CDs. The fair value s of the CDs are computed using the outstandin g principal amount. The discount rates used were based on brokered CD market rates as of the end of the year. The fair value s do not incorporate the risk of nonperformance, since interests in brokered CDs are generally sold by brokers in amounts of less t han $ 250,000 and, therefore, are insured by the FDIC. Securities sold under agreements to repurchase Some repurchase agreements reprice at least quarterly, and their outstanding balances are estimated to be their fair value. Where longer commitments are involved, fair value s are estimated using exit price indications of the cost of unwinding the transactions as of the end of the reporting period. The brokers who are the counterparties provide these indications, which the Corporation evaluates. Securities sold under agreements to repurchase are fully collateralized by investment securities. Advances from the FHLB The fair value s of advances from the FHLB with fixed maturities are determined using discounted cash flow analyses over the full terms of the b orrowings, using indications of the fair value of similar transactions. The cash flows assume no early repayment of the borrowings. Discount rates are based on the LIBOR yield curve. Advances from the FHLB are fully collateralized by mortgage loans and, to a lesser extent, investment securities. Other borrowings Other borrowings consist of junior subordinated debentures. Projected cash flows from the debentures were discounted using the Bloomberg BB Finance curve plus a credit spread. This credit spread w as estimated using the difference in yield curves between swap rates and a yield curve that considers the industry and credit rating of the Corporation as issuer of the debenture s at a tenor comparable to the time to maturity of the debentures.

These include cash and due from banks and other short-term assets, such as FHLB stock. Certain assets, the most significant being premises and equipment, mortgage servicing rights, deposits base, 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 subject to the disclosure requirements are not actively traded, requiring management to estimate fair values. These estimates necessarily involve the use of judgment about a wide variety of factors, including but not limited to, relevancy of market prices of comparable instruments, expected futures cash flows, and appropriate discount rates.

REVENUE FROM CONTRACTS WITH CUS

REVENUE FROM CONTRACTS WITH CUSTOMERS	12 Months Ended
	Dec. 31, 2018
Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	NOTE 30 – REVENUE FROM CONTRACTS WITH CUSTOMERS As noted in Note 1 – Nature of Business and Significant Accounting Policies, the Corporation adopted the provisions of ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASC Topic 606”), on January 1, 2018. Results for reporting periods beginning after December 31, 2017 are pres ented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with ASC Topic 605, “Revenue Recognition.” Revenue Recognition In accordance with ASC Topic 606, revenues are recognized when control of p romised goods or services is transferred to customers 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 det ermines 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) allo cates 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 t he 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 th e goods or services that are promised within each contract and 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 p rice 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 in struments and non-interest income, disaggregated by type of service and business segments for the year ended December 31, 2018: (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total Year ended December 31, 2018: Net interest income (1) $ 79,389 $ 217,933 $ 78,675 $ 61,628 $ 59,056 $ 28,702 $ 525,383 Service charges and fees on deposit accounts - 13,332 4,965 - 559 2,812 21,668 Insurance commissions - 7,889 - - 87 455 8,431 Merchant-related income - 3,561 748 - - 934 5,243 Credit and debit card fees - 17,538 1,225 - 618 2,061 21,442 Other service charges and fees 252 4,391 1,280 71 1,351 525 7,870 Not in scope of Topic 606 (1) 16,821 995 (3,060) 2,434 405 61 17,656 Total non-interest income 17,073 47,706 5,158 2,505 3,020 6,848 82,310 Total Revenue $ 96,462 $ 265,639 $ 83,833 $ 64,133 $ 62,076 $ 35,550 $ 607,693 (1) Most of the Corporation’s revenue is not within the scope of ASU No. 2014-09, Revenue from Contracts with Customers . The guidance explicitly excludes net interest income from financial assets and liabilities, as well as other noninterest income from loans, leases, investment securities and derivative financial instruments. For 2018, substantially all of the Corporation’s revenue under the scope of Topic 606 was related to performance obligations satisfied at a point in time. The following is a discussion of revenues within 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-suffic ient 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 contrac ts 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. As a consequence, the income recognition under the standard is not different from the Corpo ration’s practice before the adoption of this guidance. 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 t o the sale/issuance of the policy and ancillary administrative post-issuance support. The p erformance obligation will be satisfied as the policies are issued and revenue will be recognized at that point in time. In addition, contingent commission income w as found to be constrained, as defined under the new standard. Contingent comm ission income will be included i n 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, which is consistent with the Corporation’s practice before the adoption of thi s guidance. For 2018, the Corporation recognized revenue of $ 2.4 million as payments were received 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-shar ing 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 al liance performance obligation over the life of the contract, and the associated transaction price is recognized as the entity performs and any constraints over the variable consideration are resolved. There was no material change in the timing or measureme nt of revenues. The overall effect on an ongoing basis of the new revenue guidance, as compared the Corporation’s practice before the adoption of this guidance, is expected to be immaterial. Credit and Debit Card Fees Credit and debit card fees primaril y 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-First Bank customers who use a FirstBank ATM. Such fees are generally recognized concurrently with the delivery of services on a daily basis. As a consequence, the income recognition is unchanged from the Corporation’s practice before the adoption of this guidan ce. Other Fees Other fees primarily include revenues generated from wire transfers, lockboxes, and bank issuances of checks. Such fees are recognized 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. As mentioned above, during 2015, the Bank entered into a long-term strategic marketing alliance with another entity to which the Bank sol d 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 marketing and referral agreement, FirstBank shares with this entity rev enues generated by the merchant contracts over the term of the 10-year agreement. As of December 31 , 2018 and 2017, this contract liability amounted to $ 2.1 million and $ 2.4 million, respectively, which will be recognized over the remaining term of the co ntract. For 2018, the Corporation recognized revenue and contract liabilities decreased by approximately $ 0.3 million due to the completion of performance over time. There were no changes in contract liabilities due to changes in transaction price estimates.

Commitments and Contingencies Disclosure [Abstract]
REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES [Text Block]	NOTE 32 – 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 ju dgments and adjustment by the regulators with respect to minimum capital requirements, components, risk weightings, and other factors. On October 3, 2017, the New York FED terminated the Written Agreement entered into on June 3, 2010 by the Corporation an d the New York FED. However, the Corporation has agreed with the New York FED to continue to obtain the approval of the New York FED before paying dividends, receiving dividends from the Bank, making payments on subordinated debt or trust-preferred securit ies, incurring or guaranteeing debt or purchasing or redeeming any corporate stock. Although the Corporation and FirstBank became subject to the U.S. Basel III capital rules (“Basel III rules”) beginning on January 1, 2015, certain requirements of the Basel III rules are being phased-in over several years and, in general, were fully effective as of January 1, 2019. However, certain elements of the new rules have been deferred by the federal banking agencies. The Corporation and FirstBank compute risk-we ighted 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. , repurcha ses of capital instruments , dividend s and interest payments on capital instruments) and (ii) discretionary bonus payments to executive officers and heads of major business lines. The phase-in of the capital conservation buffer began on January 1, 2016 with a first year requirement of 0.625 % of additional Common Equity Tier 1 Capital (“CET1”), which is being progressively increased over a four-year period, increasing by that same percentage amount on each subse quent January 1 until it reached the fully phase d-in 2.5 % CET1 requirement on January 1, 2019 . Under the fully phased-in 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 CET1 capi tal 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 requir ed 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. In addition, as required under the Basel III rules, the Corporation’s trust- preferred securities (“TRuPs”) were fully phased out from Tier 1 capital as o f January 1, 2016. However, the Corporation’s TRuPs may continue to be included in Tier 2 capital until the instruments are redeemed or mature. On November 21, 2017, the Feder al Reserve Board, the FDIC, and the Office of the Comptroller of the Currency finalized an extension of the phase-in of certain Basel III capital rules for banks not using the Basel advanced approaches capital rule . The extension, which was effective on January 1, 2018, pauses the full transition to the Basel III treatme nt of mortgage servicing assets, certain deferred tax assets, and investments in the capital of unconsolidated financial institutions and minority interests, pending the banking agencies’ broader efforts, announ ced in September 2017, to simplify the regulator y capital rules that apply to banking organizations that are not subject to the advanced approaches capital rules . Because the advanced approaches rules apply to banking organizations with more than $ 250 billion in total consolidated assets or at least $ 10 billion in total on-balance sheet foreign exposure , the extension relief applies broadly to community, midsize, and regional banks, including the Corporation and FirstBank . Please refer to the discussion in “Part I – Item 7 – Business – Supervision and R egulation” included in the Corporation’s 2018 Form 10-K for a more complete discussion of supervision and regulatory matters and activities that affect the Corporation and its subsidiaries. The regulatory capital positions of the Corporation and FirstBank as of December 31, 2018 and 2017 were as follows: Regulatory Requirements Actual For Capital Adequacy Purposes To be Well-Capitalized-General Thresholds Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) As of December 31, 2018 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 2,118,940 24.00% $ 706,418 8.0% N/A N/A FirstBank $ 2,075,894 23.51% $ 706,426 8.0% $ 883,032 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,792,880 20.30% 397,360 4.5% N/A N/A FirstBank $ 1,656,563 18.76% 397,365 4.5% 573,971 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 1,828,984 20.71% $ 529,814 6.0% N/A N/A FirstBank $ 1,964,563 22.25% $ 529,819 6.0% $ 706,426 8.0% Leverage ratio First BanCorp. $ 1,828,984 15.37% $ 475,924 4.0% N/A N/A FirstBank $ 1,964,563 16.53% $ 475,490 4.0% $ 594,362 5.0% At December 31, 2017 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 1,989,873 22.53% $ 706,432 8.0% N/A N/A FirstBank $ 1,947,627 22.06% $ 706,218 8.0% $ 882,772 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,674,164 18.96% $ 397,368 4.5% N/A N/A FirstBank $ 1,562,431 17.70% $ 397,248 4.5% $ 573,802 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 1,675,282 18.97% $ 529,824 6.0% N/A N/A FirstBank $ 1,835,445 20.79% $ 529,663 6.0% $ 706,218 8.0% Leverage ratio First BanCorp. $ 1,675,282 14.03% $ 477,643 4.0% N/A N/A FirstBank $ 1,835,445 15.39% $ 477,056 4.0% $ 596,320 5.0% The following table summarizes commitments to extend credit and standby letters of credit as of the indicated dates: December 31, 2018 2017 (In thousands) Financial instruments whose contract amounts represent credit risk: Commitments to extend credit: Construction undisbursed funds $ 160,905 $ 77,649 Unused personal lines of credit 722,510 710,607 Commercial lines of credit 455,344 471,732 Commercial letters of credit 69,664 46,728 Standby letters of credit 2,865 2,691 The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument on commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. Management uses the same credit policies and approval process in entering into commitments and conditional obligations as it does for on-balance sheet instruments. 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 represe nt 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 th e unused credit facility at any time and without cause. In general, commercial and standby letters of credit are issued to facilitate foreign and domestic trade transactions. Normally, commercial and standby letters of credit are short-term commitments u sed to finance commercial contracts for the shipment of goods. The collateral for these letters of credit includes cash or available commercial lines of credit. The fair value of commercial and standby letters of credit is based on the fees currently charg ed for such agreements, which, as of December 31, 201 8 and 201 7 , was not significant. The Corporation obtained from GNMA commitment authority to issue GNMA mortgage-backed securities. Under this program, for 201 8 , the Corporation sold approximately $ 233.2 million (2017 - $ 235.1 million) of FHA/VA mortgage loan production into GNMA mortgage-backed securities. As of December 31, 2018 , First BanCorp. and its subsidiaries were defendants in various legal proceedings arising in the ordinary course of busi ness. On at least a quarterly basis, the Corporation assesses its liabilities and contingencies in connection with threatened and outstanding legal cases, matters and proceedings, utilizing the latest information available. For cases, matters and proceedin gs where it is both probable 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. F or cases, matters or proceedings 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 o f 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 v arious 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 cases, matters, and proceedings is inhe rently uncertain, based on information currently available, m anagement believes that the final disposition of the Corporation’s legal cases, matters or proceedings, to the extent not previously provided for, will not have a material negative 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 additional material loss in excess of any accrual) will be incurred in connection with any legal actions, 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. Base d on the Corporation’s assessment as of December 31, 2018, no such disclosures were necessary. However in the event of unexpected future developments, it is possible that the ultimate resolution of these cases, matters and proceedings, if unfavorable, may be material to the Corporation’s consolidated financial position on a particular period. Set forth below is a description of the Corporation’s significant legal proceedings: Ramírez Torres, et al. v. Banco Popular de Puerto Rico, et al. FirstBank Puerto Rico has been named Defendant in this Class Action Complaint, filed of February 17, 2017 at the Court of First Instance in San Juan, Puerto Rico. The Complaint seeks damages and preliminary injunctive relief on behalf of the purported class against Banco Popular de Puerto Rico and other financial institutions with insurance agency subsidiaries in Puerto Rico. Plaintiffs allege that Defendants have been unjustly enriched by failing to reimburse them for "good experience" commissions allegedly paid by Antilles Insurance Company and Puerto Rico Home Insurance Company. On March 30, 2017, FirstBank Puerto Rico filed a Motion to Dismiss and a Motion for Declaratory Judgment and Third Party Complaint against Antilles Insurance Company and the Insurance Comm issioner's Office. All other Defendants filed Motions to Dismiss. Antilles Insurance Company filed a Motion against the Third Party Complaint filed by FirstBank Puerto Rico, which FirstBank Puerto Rico opposed. The Insurance Commissioner's Office filed a Motion for Summary Judgment. On July 28, 2017, the Court issued a Judgment granting the Motions to Dismiss filed by Defendants, dismissing the Complaint with prejudice, except the Third Party Complaint filed by FirstBank Puerto Rico which was dismissed wit hout prejudice. On August 30, 2017, Plaintiffs filed an Appeal before the Puerto Rico Court of Appeals and FirstBank Puerto Rico filed its Opposition to Plaintiffs Appeal. On March 20, 2018, the Court of Appeals entered a Judgment revoking the lower court judgment. Oriental Bank filed for Reconsideration, which was denied. All other Defendants filed writs of Certiorari before the Puerto Rico Supreme Court on May 29, 2018. On June 26, 2018, the Puerto Rico Supreme Court issued Resolutions denying all writs o f Certiorari filed by Defendants. Oriental Bank and Banco Popular were the only two banks that filed for reconsideration. Motions for Reconsideration were denied on October 10, 2018. Oriental Bank filed a Second Motion for Reconsideration on October 12, 20 18. All Motions for Reconsideration have been denied. Case remanded to the Court of First Instance for the continuation of proceedings. No further motions have been filed by any of the Parties.

DERIVATIVE INSTRUMENTS AND HEDG

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES [Text Block]	NOTE 33 – 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 inte rest 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 December 31, 2018 and 201 7 , all derivatives held by the Corporation were considered economic undesignated hedges. These undesignat ed hedges are recorded 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 - Inter est rate cap agreements provide the right to receive cash if a reference interest rate rises above a contractual rate. The value increases as the reference interest rate rises. The Corporation enters into interest rate cap agreements for protection from ri sing 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 a re 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. These securities are used to economically hedge the FHA/VA residential mortgage loan securitizations of the mortgage-banking operations. Also reported as forward contracts are mandatory mortgage loan sales commitments entered 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 statement 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. I n these transactions, th e 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 s eparate 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 th e host contract, it is bifurcated, carried at fair value, and designated as a trading or non-hedging derivative instrument. The following table summarizes the notional amounts of all derivative instruments: Notional Amounts (1) As of December 31, 2018 2017 (In thousands) Undesignated economic hedges: Interest rate contracts: Written interest rate cap agreements $ 68,510 $ 91,010 Purchased interest rate cap agreements 68,510 91,010 Interest rate lock commitments 11,722 - Forward Contracts: Sale of TBA GNMA MBS pools 33,000 26,000 Forward loan sales commitments 6,339 - $ 188,081 $ 208,020 (1) Notional amounts are presented on a gross basis with no netting of offsetting exposure positions.

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 December 31, 201 8 , the Corporation has not entered into any derivative instrument containing credit-risk-related contingent features. Credit and Market Risk of Derivatives The Corporation uses derivative instruments to manage interest rate risk. By using derivative instruments, the Corporation is exposed to credit and market risk. If the counterparty fails to perform, credit risk is equal to the extent of the Corporation’s fair value gain o n the derivative. When the fair value of a derivative instrument contract is positive, this generally indicates that the count erparty owes the Corporation which , therefore, creates a credit risk for the Corporation. When the fair value of a derivative instrument contract is negative, the Corpo ration owes the counterparty and , therefore, it has no credit risk. The Corporation minimizes its credit risk in derivative instruments by entering into transactions with reputable broker dealers (fi nancial institutions) that are reviewed periodically by the Management Investment and Asset Liability Committee of the Corporation ( the “MIALCO”) and by the Board of Directors. The Corporation also has a policy of requiring that all derivative instrument c ontracts be governed by an International Swaps and Derivatives Association Master Agreement, which includes a provision for netting . The Corporation has a policy of diversifying derivatives counterparties to reduce the consequences of counterparty default. The Corporation has credit risk of $ 1.0 million as of December 31, 201 8 ( 2017 — $ 0.3 million) related to derivative instruments with positive fair values. The credit risk does not consider the value of any collateral and the effects of legally enf orceable master netting agreements. There were no credit losses associated with derivative instruments recognized in 201 8 , 201 7 , or 201 6 . Market risk is the adverse effect that a change in interest rates or implied volatility rates has on the value of a financial instrument. The Corporation manages the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. The Corporation’s derivative activities are monitored by the MIALCO as part of its risk-management oversight of the Corporation’s treasury functions.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	NOTE 35 – SEGMENT INFORMATION Based upon the Corporation’s organizational structure and the information provided to the Chief Executive Officer of the Corporation and, to a lesser extent, the Board of Directors, 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 December 31, 2018 , the Corporation had six reportable segm ents: 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 reporting used to e valuate 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 determ ination 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 Co rporate 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 o ther 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 and Consumer (Retail) Banking segments to finance their lending activities and borrows from those segments. The Consumer (Retail) Banking and the United States Operations segments also lend funds to other segments. The interest rates charged or credited by Treasury and Investments, the Consumer ( Retail) Banking, and the United States Operations 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 Operation s 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 an d Summary of Significant Accounting Policies , ” to the consolidated financial statements. The Corporation evaluates the performance of the segments based on net interest income, the provision for loan and lease losses, non-interest income and direct non-in terest expenses. The segments are also evaluated based on the average volume of their interest-earning assets less the allowance for loan and lease losses.

Principles of consolidation [Policy Text Block]	Principles of consolidation The consolidated financial statements include the accounts of the Corporation and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Statutory business trusts that are wholly- owned by the Corporation and are issuers of trust-preferred securities, and entities in which the Corporation has a non-controlling interest, are not consolidated in the Corporation’s consolidated financial statements in accordance with authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) for consolidation of variable interest entities (“VIE”). See “Variable Interest Entities” below for further details regarding the Corporation’s accounting policy for these entities .
Reclassifications [Policy Text Block]	Reclassifications For purposes of comparability, certain prior period amounts have been reclassified to conform to the 2018 presentation. These reclassifications include, but are not limited to, the amount of deferred tax assets, net of valuation allowance, that was p reviously presented as part of other assets, was reclassified and is presented separately in the statements of financial condition, the amount of the FDIC insurance premium expense, that was previously presented as part of Insurance and supervisory fees, w as reclassified and is presented separately in the statements of income, and the amount of supervisory fees and other insurance expenses, that was previously presented as part of Insurance and supervisory fees, was reclassified and is presented as part of Other interest non-interest expenses in the statements of income. These reclassifications had no impact on the previously reported results of operations, financial condition, or cash flows.
Use of estimates in the preparation of financial statements [Policy Text Block]	Use of estimates in the preparation of financial statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets , liabilities and contingent liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results cou ld differ from those estimates.
Cash and cash equivalents [Policy Text Block]	Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from the Federal Reserve Bank of New York (the “New York FED” or “Federal Reserve”) and other depository instituti ons. The term also includes money market funds and short-ter m investments with original maturities of three months or less and time deposits with original maturities of twelve months or less. Time deposits considered cash and cash equivalent are highly liquid and readily convertible to cash .
Investment securities [Policy Text Block]	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 Corpo ration 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 December 31, 201 8 and 201 7 , 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 other comprehensive income (“OCI”) as a separate component of stockholders’ equity, and do not affect earnings until they are realized or are deemed to be other-than-temporarily impaired. E quity securities — Equity securities that do not have readily available fair values are classified as other 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 stock that is owned by th e Corporation to comply with Federal Home Loan Bank ( “ FHLB ” ) regulatory requirements. Their realizable value equals their cost. Also included in this category are marketable equity securities held at fair value with changes in unrealized gains or losses r ecorded through earnings pursuant to the requirements of ASU 2016-01. 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. Net realized gains and losses and valuation adjustments considered other-than-temporary, if any, related to inv estment securities are determined using the specific identification method and are reported in non-interest income as net gain (loss) on sale of investments and net impairment losses on debt securities, respectively. Purchases and sales of securities are recognized on a trade-date basis.
Evaluation of other-than-temporary impairment (OTTI) on held-to-maturity and available-for-sale securities [Policy Text Block]	Evaluation of other-than-temporary impairment (“OTTI”) on held-to-maturity and available-for-sale securities On a quarterly basis, the Corporation performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered an OTTI. A security is considered impaired if the fair value is less than its amortized cost basis. The Corporation employs a systematic methodology that considers all available evidence in evaluating a potential impairment of its investments. The impairment analysis of debt securities places special emphasis on the analysis of 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 len gth of time and the extent to which the fair value has been 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 conditio n 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 C orporation 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 o f cash flows generated from the underlying collateral, if any, supporting the principal and interest payments of the debt securities. OTTI must be recognized in earnings if the Corporation has the intent to sell the debt security or it is more likely than not that it will be required to sell the debt security before recovery of its amortized cost basis. However, even if the Corporation does not expect to sell a debt security, it must evaluate expected cash flows to be received and determine if a credit los s has occurred. An unrealized loss is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. For available-for-sal e and held-to-maturity debt securities the Corporations intends to hold, the credit loss component of an OTTI, if any, is recorded as net impairment losses on debt securities in the statements of income, while the remaining portion of the impairment loss i s recognized in OCI, net of taxes, and included as a component of stockholders’ equity . The previous amortized cost basis less the OTTI recognized in earnings is the new amortized cost basis of the investment. The new amortized cost basis is not adjusted f or subsequent recoveries in fair value. Subsequent increases and decreases (if not an OTTI) in the fair value of available-for-sale securities is included in other comprehensive income. For held-to-maturity debt securities, any OTTI recognized in OCI shou ld be accreted from other comprehensive income to the amortized cost of the debt security over the remaining life of the debt security. However, debt securities for which OTTI was recognized in earnings, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income as long as th e security is not placed in nonaccrual status. Debt securities held by the Corporation at year-end primarily consisted of securities issued by U.S. government-sponsored entities, private label mortgage-backed securities (“MBS”) , certain bonds issued by the Puerto Rico Housing Finance Authority, a government instrumentality of the Commonwealth of Puerto Rico, and obligations of certain municipalities in Puerto Rico . Given the explicit and implicit guarantees provided by the U.S. f ederal government, the Corporation believes the credit risk in securities issued by the U.S. government-sponsored entities is low. The Corporation’s OTTI assessment was concentrated on Puerto R ico government debt securities and private label MBS. For further information, including methodology and assumptions used for the discounted cash flow analyses performed on these securities, refer to Note 5 – Investment Securities, to the consolidated financi al statements.
Loans held for investment [Policy Text Block]	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. The substantial majority of the Corporation’s loans are classified as held for investment. Loans are stated at the principal outstanding balance, net of unearned interest, cumulative charge-offs, u namortized deferred origination fees and costs, and unamortized premiums and discounts. 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. Credit card loans are reported at their outstanding unpaid principal balance plus uncollected billed interest and fees net of amounts deemed uncollectible. Purcha sed Credit Impaired (“ PCI ”) loans are reported net of any remaining purchase accounting adjustments. See “Loans Acquired” below for the accounting policy for PCI loans. Non accrual and Past-Due Loans - Loans on which the recognition of interest income has been discontinued are designated as non accrual . Loans are classified as non accrual 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”) or the Veterans Administration (the “VA”) and credit cards. It is the Corporation’s policy to report delinquent mortgage loans insured by the FHA , or guarantee d by the VA or the Puerto Rico Housing Authority, as loans past due 90 days and still accruing as op posed to non accrual loans since the principal repayment is insured. However, the Corporation discontinues the recognition of income for FHA/VA loans when such loans are over 15 months delinquent , taking into consideration the FHA interest curtailment proce ss, and for loans guaranteed by the Puerto Rico Housing Finance Authority when such loans are over 90 days delinquent. As permitted by regulatory guidance issued by the Federal Financial Institutions Examination Council (“FFIEC”), credit card loans are gen erally charged off in the period in which the account becomes 180 days past due. Credit card loans continue to accrue finance charges and fees until charged off at 180 days. Loans generally may be placed on non accrual status prior to when required by the p olicies 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 non accrual stat us, any accrued but uncollected interest income is reversed and charged against interest income and amortization of any net deferred fees is suspended. Interest income on non accrual loans is recognized only to the extent it is received in cash. However, wh en 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). 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. PCI loans are not reported as nonaccrual as these loans were written down to fair value at the acquisition date and the accretable yield is recognized in interest income over the remaining life of the loans. 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 payments. Impaired Loans - A loan is considered impaired when, based upon current information and events, it is probable that the Corporation will be unable to collect all amounts due (including principal and interest) according to the contr actual terms of the loan agreement, or the loan has been modified in a Troubled Debt Restructuring (“TDR”). Loans with insignificant delays or insignificant shortfalls in the amounts of payments expected to be collected are not considered to be impaired. T he Corporation evaluates individually for impairment those loans in the construction, commercial mortgage, and commercial and industrial portfolios of $1 million or more as well as any boat loan of $1 million or more. Although the authoritative accounting guidance for a specific impairment of a loan excludes large groups of smaller balance homogeneous loans that are collectively evaluated for impairment ( e.g. , mortgage an d consumer loans), it specifically requires that loan modifications considered TDR s be analyzed under its provision. The Corporation also evaluates for impairment purposes certain residential mortgage loans and home equity lines of credit with high delinqu ency and loan to value levels. Held-for-sale loans are not reported as impaired, as these loans are recorded at the lower of cost or fair value. The Corporation generally measures impairment and the related specific allowance for individually impaired lo ans based on the difference between the recorded investment of the loan and the present value of the loans’ expected future cash flows, discounted at the effective original interest rate of the loan at the time of modification, or the loan’s observable mar ket price. If the loan is collateral dependent, the Corporation measures impairment based upon the fair value of the underlying collateral, instead of discounted cash flows, regardless of whether foreclosure is probable. Loans are identified as collateral dependent if the repayment is expected to be provided solely by the underlying collateral, through liquidation or operation of the collateral. When the fair value of the collateral is used to measure impairment on an impaired collateral-dependent loan and repayment or satisfaction of the loan is dependent on the sale of the collateral, the fair value of the collateral is adjusted to consider estimated costs to sell. If repayment is dependent only on the operation of the collateral, the fair value of the col lateral is not adjusted for estimated costs to sell. If the fair value of the loan is less than the recorded investment, the Corporation recognizes impairment by either a direct write-down or establishing a specific allowance for the loan or by adjusting t he specific allowance for the impaired loan. For an impaired loan that is collateral dependent, charge-offs are taken in the period in which the loan, or a portion of the loan, is deemed uncollectible, and any portion of the loan that is not charged off is adversely credit-risk rat ed at a level no worse than substandard. A restructuring of a loan constitutes a TDR if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. TDR loans typically result from the Corporation’s loss mitigation activities and the modification of residential mortgage loans in accordance with guidelines similar to those of the U.S. government’s Home Affordable Modification Pro gram, and could include rate reductions to a rate that is below market on the loan, principal forgiveness, term extensions, payment forbearance, refinancing of any past-due amounts, including interest, escrow, and late charges and fees, and other actions i ntended to minimize the economic loss and to avoid foreclosure or repossession of collateral. Residential mortgage loans for which a binding offer to restructure has been extended are also classified as TDR loans. PCI loans are not classified as TDR loans. TDR loans are classified as either accrual or nonaccrual loans . Loans in accrual status may remain in accrual status when their contractual terms have been modified in a TDR if the loans had demonstrated performance prior to the restructuring and payment in full under the restructured terms is expected. Otherwise , loans on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure, generally for a minimum of six m onths , and there is evidence that such payments , can , and ar e likely to, continue as agreed. Refer to Note 8 – Loans Held for Investment ,” to the consolidated financial statements for additional qualitative and quantitative information about TDR loans. In connection with commercial loan restructurings, the decision to maintain a loan that has been restructured on accrual status is based on a current, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. The credit evaluation reflects consideration of the borrower’s future capacity to pay, which may include evaluation of cash flow projections, consideration of the adequacy of collateral to cover all principal and interest, and trends i ndicating improving profitability and collectability of receivables. This evaluation also includes an evaluation of the borrower’s current willingness to pay, which may include a review of past payment history, an evaluation of the borrower’s willingness t o provide information on a timely basis, and consideration of offers from the borrower to provide additional collateral or guarantor support. The evaluation of mortgage and consumer loans for restructurings includes an evaluation of the client’s disposab le income and credit report, the value of the property, the loan-to-value relationship, and certain other client-specific factors that have affected the borrower’s ability to make timely principal an d interest payments on the loan . The Corporation remove s loans from TDR classification, consistent with authoritative guidance that allows for a TDR to be removed from this classification in years following the modification, only when the following two circumstances are met: The loan is in compliance with the terms of the restructuring agreement and, therefore, is not considered impaired under the revised terms; and The loan yields a market interest rate at the time of the restructuring. In other words, the loan was restructured with an interest rate equal to or greater than what the Corporation would have been willing to accept at the time of the restructuring for a new loan with comparable risk. If both of the conditions are met, the loan can be removed from the TDR classification in calendar years after th e year in which the restructuring took place. However, the loan continues to be individually evaluated for impairment. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. With respect t o the restructuring of a loan into two new loan notes, or loan splits, g enerally Note A of a loan split is restructur ed under market terms, and Note B is fully charged off. If Note A is in compliance with the restructured terms in years following the restructuring, Note A will be removed from the TDR classification and will continue to be individually evaluated for impairment. Refer to Note 8 – Loans Held for Investment, to the consolidated financial statements , for additional information about loan splits. A loan that had previously been modified in a TDR and is subsequently refina nced under current underwriting standards at a market rate with no concessionary terms is accounted for as a new loan and is no longer reported as a TDR. Interest income on impaired loans is recognized based on the Corporation’s policy for recogniz ing int erest on accrual and non accrual loans. Loans Acquired - All purchased loans are recorded at fair value at the date of acquisition. Loans acquired with evidence of credit deterioration since their origination and where it is probable at the date of acquisit ion that the Corporation will not collect all contractually required principal and interest payments are considered PCI loans. Evidence of credit quality deterioration as of the purchase date may include stat istics such as past due and non accrual status, c redit scores, and revised loan terms. PCI loans have been aggregated into pools based on common risk characteristics. Each pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. In accounti ng for PCI loans, the difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. The nonaccretable difference, which is neither accreted into income nor reco rded on the consolidated statements of financial condition, reflects estimated future credit losses expected to be incurred over the life of the pool of loans. The excess of cash flows expected to be collected over the estimated fair value of PCI loans is referred to as the accretable yield. This amount is not recorded on the statements of financial condition, but is accreted into interest income over the remaining life of the pool of loans, using the effective-yield method. Subsequent to acquisition, the Corporation continues to estimate cash flows expected to be collected over the life of the PCI loans using models that incorporate current key assumptions such as default rates, loss severity, and prepayment speeds. Decreases in expected cash flows will generally result in an impairment charge to the provision for loan and lease losses and the establishment of an allowance for loan and lease losses. Increases in expected cash flows will generally result in a reduction in any a llowance for loan and lease losses established subsequent to acquisition and an increase in the accretable yield. The adjusted accretable yield is recognized in interest income over the remaining life of the pool of loans. Resolutions of loans may include sales of loans to third parties, receipt of payments in settlement with the borrower, or foreclosure of the collateral. The Corporation’s policy is to remove an individual loan from a pool at its relative carrying amount. The carrying amount is defined as the loan’s current contractually required payments receivable less its remaining nonaccretable difference and accretable yield, but excluding any post-acquisition loan loss allowance. To determine the carrying value, the Corporation performs a pro-rata al location of the pool’s total remaining nonaccretable difference and accretable yield to an individual loan in proportion to the loan’s current contractually required payments receivable compared to the pool’s total contractually required payments receivabl e. This removal method assumes that the amount received from resolution approximates pool performance expectations. The remaining accretable yield balance is unaffected and any material change in the remaining effective yield caused by this removal method is addressed by the Corporation’s quarterly cash flow evaluation process for each pool. Modified PCI loans are not removed from a pool even if those loans would otherwise be deemed TDRs. Because the initial fair value of PCI loans recorded at acquisition includes an estimate of credit losses expected to be realized over the remaining lives of the loans, the Corporation separately tracks and reports PCI loans and excludes these loans from its delinquency and non accrual loan statistics. For acquired loans that are not deemed impaired at acquisition, subsequent to acquisition, the Corporation recognizes the difference between the initial fair value at acquisition and the undiscounted expected cash flows in interest income over the period in which substantial ly all of the inherent losses associated with the non-PCI loans at the acquisition date are estimated to occur. Thus, such loans are accounted for consistently with other originated loans, potentially being classified as nonaccrual or impaired, as well as being classified under the Corporation’s standard practice and procedures. In addition, these loans are considered in the determination of the allowance for loan losses. Charge-off of Uncollectible Loans - Net charge-offs consist of the unpaid principal balances of loans held for investment that the Corporation determines are uncollectible, net of recovered amounts. Charge-offs are recorded as a reduction to the allowance for loan and lease losses and subse quent recoveries of previously charged off amounts are credited to the allowance for loan and lease losses. Collateral dependent loans in the construction, commercial mortgage, and commercial and industrial loan portfolios are charged off to their net real izable value (fair value of collateral, less estimated costs to sell) when loans are considered to be uncollectible. Within the consumer loan portfolio, auto loans and finance leases are reserved once they are 120 days delinquent and are charged off to th eir estimated net realizable value when the collateral deficiency is deemed uncollectible ( i.e. , when foreclosure/repossession is probable) or when the loan is 365 days past due. Within the other consumer loan portfolio , closed-end loans are charged off w hen payments are 120 days in arrears, except small personal loans. Open-end (revolving credit) consumer loans, including credit card loans, and small personal loans are charged off when payments are 180 days in arrears. On a quarterly basis, residential mo rtgage loans that are 180 days delinquent and have an original loan-to-value ratio that is higher than 60% are reviewed and charged-off, as needed, to the fair value of the underlying collateral. Generally, all loans may be charged off or written down to t he fair value of the collateral prior to the application of the policies described above if a loss-confirming event has occurred. Loss-confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, or receipt of an asset valuation indicating a collateral deficiency when the asset is the sole source of repayment. The Corporation does not record charge-offs on PCI loans that are performing in accordance with or better than expectations as of the date of acquisition, as the f air value of these loans already reflects a credit component. The Corporation records charge-offs on PCI loans only if actual losses exceed estimated losses incorporated into the fair value recorded at acquisition and the amount is deemed uncollectible.
Nonaccrual and Past Due Loans [Policy Text Block]	Non accrual and Past-Due Loans - Loans on which the recognition of interest income has been discontinued are designated as non accrual . Loans are classified as non accrual 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”) or the Veterans Administration (the “VA”) and credit cards. It is the Corporation’s policy to report delinquent mortgage loans insured by the FHA , or guarantee d by the VA or the Puerto Rico Housing Authority, as loans past due 90 days and still accruing as op posed to non accrual loans since the principal repayment is insured. However, the Corporation discontinues the recognition of income for FHA/VA loans when such loans are over 15 months delinquent , taking into consideration the FHA interest curtailment proce ss, and for loans guaranteed by the Puerto Rico Housing Finance Authority when such loans are over 90 days delinquent. As permitted by regulatory guidance issued by the Federal Financial Institutions Examination Council (“FFIEC”), credit card loans are gen erally charged off in the period in which the account becomes 180 days past due. Credit card loans continue to accrue finance charges and fees until charged off at 180 days. Loans generally may be placed on non accrual status prior to when required by the p olicies 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 non accrual stat us, any accrued but uncollected interest income is reversed and charged against interest income and amortization of any net deferred fees is suspended. Interest income on non accrual loans is recognized only to the extent it is received in cash. However, wh en 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). 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. PCI loans are not reported as nonaccrual as these loans were written down to fair value at the acquisition date and the accretable yield is recognized in interest income over the remaining life of the loans. 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 payments. Charge-off of Uncollectible Loans - Net charge-offs consist of the unpaid principal balances of loans held for investment that the Corporation determines are uncollectible, net of recovered amounts. Charge-offs are recorded as a reduction to the allowance for loan and lease losses and subse quent recoveries of previously charged off amounts are credited to the allowance for loan and lease losses. Collateral dependent loans in the construction, commercial mortgage, and commercial and industrial loan portfolios are charged off to their net real izable value (fair value of collateral, less estimated costs to sell) when loans are considered to be uncollectible. Within the consumer loan portfolio, auto loans and finance leases are reserved once they are 120 days delinquent and are charged off to th eir estimated net realizable value when the collateral deficiency is deemed uncollectible ( i.e. , when foreclosure/repossession is probable) or when the loan is 365 days past due. Within the other consumer loan portfolio , closed-end loans are charged off w hen payments are 120 days in arrears, except small personal loans. Open-end (revolving credit) consumer loans, including credit card loans, and small personal loans are charged off when payments are 180 days in arrears. On a quarterly basis, residential mo rtgage loans that are 180 days delinquent and have an original loan-to-value ratio that is higher than 60% are reviewed and charged-off, as needed, to the fair value of the underlying collateral. Generally, all loans may be charged off or written down to t he fair value of the collateral prior to the application of the policies described above if a loss-confirming event has occurred. Loss-confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, or receipt of an asset valuation indicating a collateral deficiency when the asset is the sole source of repayment. The Corporation does not record charge-offs on PCI loans that are performing in accordance with or better than expectations as of the date of acquisition, as the f air value of these loans already reflects a credit component. The Corporation records charge-offs on PCI loans only if actual losses exceed estimated losses incorporated into the fair value recorded at acquisition and the amount is deemed uncollectible.
Impaired Loans [Policy Text Block]	Impaired Loans - A loan is considered impaired when, based upon current information and events, it is probable that the Corporation will be unable to collect all amounts due (including principal and interest) according to the contr actual terms of the loan agreement, or the loan has been modified in a Troubled Debt Restructuring (“TDR”). Loans with insignificant delays or insignificant shortfalls in the amounts of payments expected to be collected are not considered to be impaired. T he Corporation evaluates individually for impairment those loans in the construction, commercial mortgage, and commercial and industrial portfolios of $1 million or more as well as any boat loan of $1 million or more. Although the authoritative accounting guidance for a specific impairment of a loan excludes large groups of smaller balance homogeneous loans that are collectively evaluated for impairment ( e.g. , mortgage an d consumer loans), it specifically requires that loan modifications considered TDR s be analyzed under its provision. The Corporation also evaluates for impairment purposes certain residential mortgage loans and home equity lines of credit with high delinqu ency and loan to value levels. Held-for-sale loans are not reported as impaired, as these loans are recorded at the lower of cost or fair value. The Corporation generally measures impairment and the related specific allowance for individually impaired lo ans based on the difference between the recorded investment of the loan and the present value of the loans’ expected future cash flows, discounted at the effective original interest rate of the loan at the time of modification, or the loan’s observable mar ket price. If the loan is collateral dependent, the Corporation measures impairment based upon the fair value of the underlying collateral, instead of discounted cash flows, regardless of whether foreclosure is probable. Loans are identified as collateral dependent if the repayment is expected to be provided solely by the underlying collateral, through liquidation or operation of the collateral. When the fair value of the collateral is used to measure impairment on an impaired collateral-dependent loan and repayment or satisfaction of the loan is dependent on the sale of the collateral, the fair value of the collateral is adjusted to consider estimated costs to sell. If repayment is dependent only on the operation of the collateral, the fair value of the col lateral is not adjusted for estimated costs to sell. If the fair value of the loan is less than the recorded investment, the Corporation recognizes impairment by either a direct write-down or establishing a specific allowance for the loan or by adjusting t he specific allowance for the impaired loan. For an impaired loan that is collateral dependent, charge-offs are taken in the period in which the loan, or a portion of the loan, is deemed uncollectible, and any portion of the loan that is not charged off is adversely credit-risk rat ed at a level no worse than substandard.
TDR loans [Policy Text Block]	A restructuring of a loan constitutes a TDR if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. TDR loans typically result from the Corporation’s loss mitigation activities and the modification of residential mortgage loans in accordance with guidelines similar to those of the U.S. government’s Home Affordable Modification Pro gram, and could include rate reductions to a rate that is below market on the loan, principal forgiveness, term extensions, payment forbearance, refinancing of any past-due amounts, including interest, escrow, and late charges and fees, and other actions i ntended to minimize the economic loss and to avoid foreclosure or repossession of collateral. Residential mortgage loans for which a binding offer to restructure has been extended are also classified as TDR loans. PCI loans are not classified as TDR loans. TDR loans are classified as either accrual or nonaccrual loans . Loans in accrual status may remain in accrual status when their contractual terms have been modified in a TDR if the loans had demonstrated performance prior to the restructuring and payment in full under the restructured terms is expected. Otherwise , loans on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure, generally for a minimum of six m onths , and there is evidence that such payments , can , and ar e likely to, continue as agreed. Refer to Note 8 – Loans Held for Investment ,” to the consolidated financial statements for additional qualitative and quantitative information about TDR loans. In connection with commercial loan restructurings, the decision to maintain a loan that has been restructured on accrual status is based on a current, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. The credit evaluation reflects consideration of the borrower’s future capacity to pay, which may include evaluation of cash flow projections, consideration of the adequacy of collateral to cover all principal and interest, and trends i ndicating improving profitability and collectability of receivables. This evaluation also includes an evaluation of the borrower’s current willingness to pay, which may include a review of past payment history, an evaluation of the borrower’s willingness t o provide information on a timely basis, and consideration of offers from the borrower to provide additional collateral or guarantor support. The evaluation of mortgage and consumer loans for restructurings includes an evaluation of the client’s disposab le income and credit report, the value of the property, the loan-to-value relationship, and certain other client-specific factors that have affected the borrower’s ability to make timely principal an d interest payments on the loan . The Corporation remove s loans from TDR classification, consistent with authoritative guidance that allows for a TDR to be removed from this classification in years following the modification, only when the following two circumstances are met: The loan is in compliance with the terms of the restructuring agreement and, therefore, is not considered impaired under the revised terms; and The loan yields a market interest rate at the time of the restructuring. In other words, the loan was restructured with an interest rate equal to or greater than what the Corporation would have been willing to accept at the time of the restructuring for a new loan with comparable risk. If both of the conditions are met, the loan can be removed from the TDR classification in calendar years after th e year in which the restructuring took place. However, the loan continues to be individually evaluated for impairment. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. With respect t o the restructuring of a loan into two new loan notes, or loan splits, g enerally Note A of a loan split is restructur ed under market terms, and Note B is fully charged off. If Note A is in compliance with the restructured terms in years following the restructuring, Note A will be removed from the TDR classification and will continue to be individually evaluated for impairment. Refer to Note 8 – Loans Held for Investment, to the consolidated financial statements , for additional information about loan splits. A loan that had previously been modified in a TDR and is subsequently refina nced under current underwriting standards at a market rate with no concessionary terms is accounted for as a new loan and is no longer reported as a TDR. Interest income on impaired loans is recognized based on the Corporation’s policy for recogniz ing int erest on accrual and non accrual loans.
Loans Acquired [Policy Text Block]	Loans Acquired - All purchased loans are recorded at fair value at the date of acquisition. Loans acquired with evidence of credit deterioration since their origination and where it is probable at the date of acquisit ion that the Corporation will not collect all contractually required principal and interest payments are considered PCI loans. Evidence of credit quality deterioration as of the purchase date may include stat istics such as past due and non accrual status, c redit scores, and revised loan terms. PCI loans have been aggregated into pools based on common risk characteristics. Each pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. In accounti ng for PCI loans, the difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. The nonaccretable difference, which is neither accreted into income nor reco rded on the consolidated statements of financial condition, reflects estimated future credit losses expected to be incurred over the life of the pool of loans. The excess of cash flows expected to be collected over the estimated fair value of PCI loans is referred to as the accretable yield. This amount is not recorded on the statements of financial condition, but is accreted into interest income over the remaining life of the pool of loans, using the effective-yield method. Subsequent to acquisition, the Corporation continues to estimate cash flows expected to be collected over the life of the PCI loans using models that incorporate current key assumptions such as default rates, loss severity, and prepayment speeds.

Thus, such loans are accounted for consistently with other originated loans, potentially being classified as nonaccrual or impaired, as well as being classified under the Corporation’s standard practice and procedures. In addition, these loans are considered in the determination of the allowance for loan losses.
Loans held for sale [Policy Text Block]	L oans held for sale Loans that the Corporation intends to sell or that the Corporation does not have the ability and intent to hold for the foreseeable future are classified as held-for-sale loans. Loans held for sale are stated at the lower of aggregate c ost or fair value. Generally, the loans held-for-sale portfolio consists of conforming residential mortgage loans that the Corporation intends to sell to the Government National Mortgage Association (“GNMA”) and government-sponsored entities (“GSEs”) , suc h as the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”). Generally, residential mortgage loans held for sale are valued on an aggregate portfolio basis and the value is primarily derived from quotati ons based on the mortgage-backed securities market. The amount by which cost exceeds market value in the aggregate portfolio of loans held for sale, if any, is accounted for as a valuation allowance with changes therein included in the determination of net income and reported as part of mortgage banking activities in the consolidated statements of income. Loan costs and fees are deferred at origination and are recognized in income at the time of sale. The fair value of commercial and construction loans held for sale is primarily derived from external appraisals , or broker price opinions that the Corporation considered, with changes in the valuation allowance reported as part of other non-interest income in the consolidated statements of income. In certain circumstances, the Corporation transfers loans from/to held for sale or held for investment based on a change in strategy. If such a change in holding strategy is made, significant adjustments to the loans’ carrying values may be necessary. Reclassificatio ns of loans held for investment to held for sale are made at the lower of cost or fair value on the date of transfer and establish a new cost basis upon transfer. Write-downs of loans transferred from held for investment to held for sale are recorded as ch arge-offs at the time of transfer. Subsequent changes in value below amortized cost are recorded through non-interest income. Reclassifications of loans held for sale to held for investment are made at fair value on the date of transfer. Any difference bet ween the carrying value and the fair value of a reclassified loan is recorded as an adjustment to non-interest income, prospectively, over the remaining life of the loan .
Allowance for loan and lease losses [Policy Text Block]	Allowance for loan and lease losses The Corporation maintains the allowance for loa n and lease losses at a level considered adequate to absorb incurred losses currently inherent in the loan and lease portfolio. The Corporation does not maintain an allowance for held-for-sale loans or PCI loans that are performing in accordance with or be tter than expectations as of the date of acquisition, as the fair values of these loans already reflect a credit component. The allowance for loan and lease losses provides for probable incurred losses that have been identified with specific valuation allo wances for individually evaluated impaired loans and for probable incurred losses believed to be inherent in the loan portfolio that have not been specifically identified. The determination of the allowance for loan and lease losses requires significant es timates, including with respect to the timing and amounts of expected future cash flows on impaired loans, consideration of current economic conditions and business strategies , and historical loss experience pertaining to the portfolios and pools of homoge neous loans, all of which may be susceptible to change. The Corporation evaluates the need for changes to the allowance by portfolio loan segments and classes of loans within certain of those portfolio segments. The Corporation combines loans with similar credit risk characteristics into the following portfolio segments: commercial mortgage, construction, commercial and industrial, residential mortgage, and consumer loans. Classes are usually disaggregations of the portfolio segments. The classes wi thin the residential mortgage segment are residential mortgages guaranteed by the U.S. government and other residential loans. The classes within the consumer portfolio are auto, finance lease, and other consumer loans. Other consumer loans mainly include unsecured personal loans, credit cards, home equity lines, lines of credits, and marine financing. The classes within the construction loan portfolio are land loans, construction of commercial projects, and construction of residential projects. The commer cial mortgage and commercial and industrial segments are not further segmented into classes. The adequacy of the allowance for loan and lease losses is based on judgments related to the credit quality of each portfolio segment. These judgments consider ong oing evaluations of each portfolio segment, including such factors as the economic risks associated with each loan class, the financial condition of specific borrowers, the geography (Puerto Rico, Florida or the Virgin Islands), the level of delinquent loa ns, historical loss experience, the value of any collateral and, where applicable, the existence of any guarantees or other documented support. In addition to the general economic conditions and other factors described above, additional factors considered include the internal risk ratings assigned to loans. An internal risk rating is assigned to each commercial and construction loan at the time of approval and is subject to subsequent periodic review by the Corporation's senior management. The allowance f or loan and lease losses is reviewed on a quarterly basis as part of the Corporation’s continued evaluation of its asset quality. The allowance for loan and lease losses is increased through a provision for credit losses that is charged to earnings, based on the quarterly evaluation of the factors previously mentioned, and is reduced by charge-offs, net of recoveries. The allowance for loan and lease losses consists of specific reserves based upon valuations of loans considered to be impaired and genera l reserves. A specific valuation allowance is established for individual impaired loans in the commercial mortgage, construction, and commercial and industrial portfolios and certain boat loans , residential mortgage loans, and home equity lines of credit, primarily when the collateral value of the loan (if the impaired loan is determined to be collateral dependent) or the present value of the expected future cash flows discounted at the loan’s effective rate is lower than the carrying amount of that loan. T he loans within the commercial mortgage, construction, commercial and industrial portfolios , and boat loans of $1 million or more are individually evaluated for impairment. Also, certain residential mortgage loans and home equity lines of credit are indivi dually evaluated for impairment purposes based on their delinquency and loan to value levels. When foreclosure of a collateral dependent loan is probable, the impairment measure is based on the fair value of the collateral. The fair value of the collatera l is generally obtained from appraisals. Updated appraisals are obtained when the Corporation determines that loans are impaired and are generally updated annually thereafter according to the Corporation’s appraisal policy. In addition, appraisals and/or a ppraiser price opinions are also obtained for residential mortgage loans based on specific characteristics such as delinquency levels, age of the appraisal, and loan-to-value ratios. The excess of the recorded investment in a collateral dependent loan ove r the resulting fair value of the collateral is charged-off when deemed uncollectible. For all other loans, which include small, homogeneous loans, such as auto loans, and the other classes in the consumer loan portfolio, residential mortgages and commer cial and construction loans not individually evaluated for impairment , the Corporation maintains a general valuation allowance established through a process that begins with estimates of incurred losses based upon various statistical analyses. The general reserve is primarily determined by applying loss factors according to the loan type and assigned risk category (pass, special mention, and substandard loans that are not considered to be impaired; all doubtful loans are considered impaired). The Corporat ion uses a roll-rate methodology to estimate losses on its consumer loan portfolio based on delinquencies and considering credit bureau score bands. The Corporation tracks the historical portfolio performance to arrive at a weighted-average distribution in each subgroup of each delinquency bucket. Roll-to-loss rates (loss factors) are calculated by multiplying the roll rates from each subgroup within the delinquency buckets forward through loss. Once roll rates are calculated, the resulting loss factor is a pplied to the existing receivables in the applicable subgroups within the delinquency buckets and the end results are aggregated to arrive at the required allowance level. The Corporation’s assessment also involves evaluating key qualitative and environmen tal factors, which include credit and macroeconomic indicators such as unemployment, bankruptcy trends, recent market transactions, and collateral values to account for current market conditions that are likely to cause estimated credit losses to differ fr om historical loss experience. The Corporation analyzes the expected delinquency migration to determine the future volume of delinquencies. The cash flow analysis for each residential mortgage pool is performed at the individual loan level and then aggr egated to the pool level in determining the overall loss ratio (the “base methodology”) . The model applies risk-adjusted prepayment curves, default curves, and severity curves to each loan in the pool. For loan restructuring pools , the present value of fut ure cash flows under the new terms, at the loan’s effective interest rate, is taken into consideration. Additionally, estimates of default risk and prepayments related to loan restructurings are based on, among other things, the historical experience of th ese loans. Loss severity is affected by the house price scenario, which is based in part on recent house price trends. Default curves are used in the model . T he attributes that are most significant to the probability of default include present collection s tatus (current, delinquent, in bankruptcy, in foreclosure stage), vintage, loan-to-values, and geography (Puerto Rico, Florida or the Virgin Islands). The estimates of the risk-adjusted timing of liquidations and associated costs are used in the model, and are risk-adjusted for the geographic area in which each property is located. For commercial loans, historical charge-off rates are calculated by the Corporation on a quarterly basis for each commercial loan regulatory-based credit risk category ( i.e. p ass, special mention, substandard, and doubtful) using the historical charge-offs and portfolio balances over their average loss emergence period (the “raw loss rate”) for each credit risk classification . However, when not enough loss experience is observe d in a particular risk-rated category and the calculation results in a loss rate for such risk-rated category that is lower than the loss rate of a less severe risk-rated category, the Corporation uses the loss rate of such less severe category. A qualita tive factor adjustment is applied to the base rate average utilizing a resulting factor derived from a set of risk-based ratings and weights assigned to credit and economic indicators over a reasonable period applied to a developed expected range of histor ical losses and a basis point adjustment derived from the difference between the average raw loss rate and the highest loss rate observed during a look-back period that management determined was appropriate to use for each region to identify any relevant e ffect during an economic cycle. During 2017, management established a separate qualitative element of the allowance to estimate inherent losses associated with the effect of Hurricanes Maria and Irma on the Corporation’s loan portfolios in Puerto Rico and Virgin Islands. This qualitative element of the allowance was initially determined based on the estimated effect that the hurricanes could have on employment levels ( e.g. , an unemployment rate that significantly increases from levels in Pue rto Rico at the time of the hurricanes based on statistics observed in the aftermath of similar natural disasters in the U.S . mainland like Hurricane Katrina) , economic activity in the Corporation’s geographic regions, and the time it could take for the af fected regions to return to a more normalized operating environment. For large commercial and construction loan relationships, loan officers performed individual reviews of the effect of the hurricanes on these borrowers’ sources of repayment. These large relationships, that represented 80 % of the outstanding balance of the Corporation’s commercial and construction loan portfolio at the time of the hurricanes, were analyzed and divided into three hurricane-affected categories ( i.e. Low, Medium and High). Clients categorized as Low had no effect, or relatively insignificant e ffect, as a result of the storms. Clients in the Medium category had demonstrated that they had sufficient liquidity to satisfy their obligations, but the complexity of the insurance claim process may affect their primary or secondary source of repayment. Finally, clients categorized as High could potentially have problems with their primary or secondary sources of repayment as they have a higher degree of uncertainty with respect to the timing of the insurance claim resolution, and the full reestablishment of their businesses is highly dependent on the timely receipt of insurance proceeds. Reserve levels were then recognized for these particular loans based on this stratification. For loans in the Low category, no additional qualitative hurricane-related re serve was calculated. For loans in the Medium and High categories, the Corporation stressed the general reserve loss factors applicable to these loans to reflect higher default probabilities not reflected in the historical data. This review also resulted in downgrades in the credit risk classification of certain loans and their reserves were determined following the methodology applicable to criticized and adversely classified loans, as appropriate. During 2018, the Corporation performed additional proc edures to evaluate the adequacy of the qualitative reserve, including the consideration of updated payment patterns and probability of default credit risk analyses applied to consumer loan borrowers subject to payment deferral programs that expired early i n 2018. For the determination of the hurricane-related qualitative reserve for residential mortgage loans as of December 31, 2018, the Corporation stressed the loss factors derived from its above-described base methodology by incorporating assumptions of f urther deterioration in the housing price index and higher loan modification levels. Although the foreclosure moratoriums extended by the FHA to hurricane-affected individuals ended on September 15, 2018, there are likely to be additional delays in foreclo sure actions due to court related backlogs. For the determination of the hurricane-related qualitative reserve for commercial and construction loans not individually reviewed as of December 31, 2018, the Corporation segregated the portfolio based on delinq uency levels and stressed the general reserve loss factors applicable to 30-89 days past due loans to reflect higher default probabilities. Refer to Note 2 – Effect s of Natural Disasters, to the consolidated financial statements, for additional information about the effect of Hurricanes Maria and Irma in the Corporation financial results. Refer to Note 9 – Allowance for Loan and Lease Losses, to the consolidated financial statements, for additional information, including the balance of the hurricane-relat ed qualitative allowance for each portfolio segment and accounting policy with respect to the reserve for unfunded lending commitment s , such as letters of credit and biding unfunded loan commitments.
Transfers and servicing of financial assets and extinguishment of liabilities [Policy Text Block]	Transfers and servicing of financial assets and e xtinguishment of liabilities After a transfer of financial assets in a transaction that qualifies for sale accounting, the Corporation derecognizes the financial assets when control has been surrendered, and derecognizes liabilities when they are extinguished. The transfer of financial assets in which the Corporation surrenders control over the assets is accounted for as a sale to the extent that consideration other than beneficial interests is received in exchange. The criteria that must be met to determine that the control over transferred assets has been surrendered include: (1) the assets must be isolated from creditors of the trans feror; (2) the transferee must obtain the right (free of conditions that constrain it from taking advantage of t hat right) to pledge or exchange the transferred assets; and (3) the transferor cannot maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. When the Corporation transfers financial assets an d the transfer fails any one of the above criteria, the Corporation is prevented from derecognizing the transferred financial assets and the transaction is accounted for as a secured borrowing.
Servicing Assets [Policy Text Block]	Servicing a ssets The Corporation recognizes as separate assets the rights to service loans for others, whether those servicing assets are originated or purchased. In the ordinary course of business, the Corporation sells residential mortgage loans (originated or purchased) to GNMA, which generally securitizes the transferred loans into mortgage-backed securities for sale into the secondary market. Also, certain conventional conforming loans are sold to FNMA or FHLMC , with servicing retained. When the Corporation sells mortgage loans, it recognizes any retained servicing right, based on its fair value. Servicing assets (“MSRs”) retained in a sale or securitization arise from contractual agreements between the Corporation and investors in mortgage securities and mortgage loans. The value of MSRs is derived from the net positive cash flows associated with the servicing contracts. Under these contracts, the Corporation performs loan-servicing functions in exchange for fees and other remuneration. The servicing functions typically include: collecting and remitting loan payments, responding to borrower inquiries, accounting for principal and interest, holding custodial funds for payment of property taxes and insurance premiums, supervising foreclosures and property dispositions, and generally administering the loans. The servicing rights, included as part of other assets in the statements of financial condition, entitle the Corpo ration to servicing fees based on the outstanding principal balance of the mortgage loans and the contractu al servicing rate. The servicing fees are credited to income on a monthly basis when collected and recorded as part of mortgage banking activities in the consolidated statements of income. In addition, the Corporation generally receives other remuneration consisting of mortgagor-contracted fees such as late charges and prepayment penalties, which are credited to income when collected. Considerable judgment is required to determine the fair value of the Corporation’s MSRs. Unlike highly liquid investments, the market value of MSRs cannot be readily determined because these assets are not actively traded in securities markets. The initial carrying value of the MSRs is generally determined based on its fair value. The fair value of the MSRs is determined bas ed on a combination of market information on trading activity (MSR trades and broker valuations), benchmarking of servicing assets (valuation surveys), and cash flow modeling. The valuation of the Corporation’s MSRs incorporates two sets of assumptions: (1 ) market-derived assumptions for discount rates, servicing costs, escrow earnings rates, floating earnings rates, and the cost of funds ; and (2) market assumptions calibrated to the Corporation’s loan characteristics and portfolio behavior for escrow balan ces, delinquencies and foreclosures, late fees, prepayments, and prepayment penalties. Once recorded, MSRs are periodically evaluated for impairment. Impairment occurs when the current fair value of the MSRs is less than its carrying value. If MSRs are i mpaired, the impairment is recognized in current-period earnings and the carrying value of the MSRs is adjusted through a valuation allowance. If the value of the MSRs subsequently increases, the recovery in value is recognized in current period earnings a nd the carrying value of the MSRs is adjusted through a reduction in the valuation allowance. For purposes of performing the MSR impairment evaluation, the servicing portfolio is stratified on the basis of certain risk characteristics such as region, terms , and coupons. An other-than-temporary impairment analysis is prepared to evaluate whether a loss in the value of the MSRs in a particular stratum , if any, is other than temporary or not. When the recovery of the value is unlikely in the foreseeable future , a write-down of the MSRs in the stratum to its estimated recoverable value is charged to the valuation allowance. As of December 31, 201 8 , the carrying value of the MSRs amounted to $ 27.4 million (201 7 - $ 25.3 million). The servicing assets are amortize d over the estimated life of the underlying loans based on an income forecast method as a reduction of servicing income. The income forecast method of amortization is based on projected cash flows. A particular periodic amortization is calculated by applyi ng to the carrying amount of the MSRs the ratio of the cash flows projected for the current period to total remaining net MSR forecasted cash flow.
Premises and equipment [Policy Text Block]	Premises and equipment Premises and equipment are carried at cost, net of accumulated depreciation and amortization. Depreciation is provided on the straight-line method over the estimated useful life of each type of asset. Amortization of leasehold improvements is computed ov er the terms of the leases (contractual term plus lease renewals that are reasonably assured) or the estimated useful lives of the improvements, whichever is shorter. Costs of maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred. Costs of renewals and betterments are capitalized. When assets are sold or disposed of, their cost and related accumulated depreciation are removed from the accounts and any gain or loss is reflected in earnings as part o f other non-interest income in the statements of income. When the asset is no longer used in operations, and the Corporation intends to sell it, the asset is reclassified to other assets held for sale and is reported at the lower of carrying amount or fair value less cost to sell. The Corporation has operating lease agreements primarily associated with the rental of premises to support the branch network or for general office space. Certain of these arrangements are noncancelable and provide for rent esca lation and renewal options. Refer to “Recently issued accounting standards and recently adopted accounting pronouncements – Lease Accounting” below for new accounting guidance with respect to the leasing transactions in effect since January 1, 2019.
Other real estate owned (OREO) [Policy Text Block]	Other real estate owned (OREO) OREO, which consists of real estate acquired in settlement of loans, is recorded at the lower of cost (carrying value of the loan) or fair value minus estimated costs to sell the real estate acquired. Generally, loans have b een written down to their net realizable value prior to foreclosure. Any further reduction to their net realizable value is recorded with a charge to the allowance for loan losses at the time of foreclosure or short ly there after. Thereafter, gains or losse s resulting from the sale of these properties and losses recognized on the periodic reevaluations of these properties are credited or charged to earnings and are included as part of net loss on OREO operations in the statements of income. The cost of maint aining and operating these properties is expensed as incurred. The Corporation estimates fair values primarily based on appraisals, when available, and the net realizable value is reviewed and updated periodically depending on the type of property involved .
Goodwill and other intangible assets [Policy Text Block]	Goodwill and other intangible assets Goodwill – Goodwill is the purchase premium after adjusting for the fair value of net assets acquired. Goodwill is not amortized but is reviewed for potential impairment on an annual basis, generally during the fo urth quarter, or more often if events or circumstances indicate there may be an impairment. The Corporation evaluated goodwill for impairment as of October 1, 201 8 . Goodwill impairment testing is performed at the segment (or “reporting unit”) level. Goodw ill is assigned to reporting units at the date the goodwill is initially recorded. Once goodwill has been assigned to a reporting unit, it no longer retains its association with a particular acquisition, and all of the activities within a reporting unit, whether acquired or internally generated, are available to support the value of the goodwill. The Corporation’s goodwill is related to the U.S. (Florida) reporting unit . The Corporation bypassed the qualitative assessment in 201 8 and proceeded directly to perform the first step of the two-step goodwill impairment test. The first step (“Step 1”) involves a comparison of the estimated fair value of the reporting unit to its carrying value, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. If the carrying value exceeds the estimated fair value, there is an indication of potential impairment and the second step is performed to measure the amount of the impairment. The second step (“Step 2”), if necessary, involves calculating an implied fair value of the goodwill for each reporting unit for which Step 1 indicated a potential impairment. The implied fair value of goodwill is determined in a manner simila r to the calculation of the amount of goodwill in a business combination, by measuring the excess of the estimated fair value of the reporting unit, as determined in Step 1, over the aggregate estimated fair values of the individual assets, liabilities, an d identifiable intangibles as if the reporting unit was then being acquired in a business combination. If the implied fair value of goodwill exceeds the carrying value of goodwill assigned to the reporting unit, there is no impairment. If the carrying va lue of goodwill assigned to a reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess. An impairment loss cannot exceed the carrying value of goodwill assigned to a reporting unit, and the loss establ ishes a new basis in the goodwill. Subsequent reversal of goodwill impairment losses is not permitted. In determining the fair value of a reporting unit, which is based on the nature of the business and the reporting unit’s current and expected financial performance, the Corporation uses a combination of methods, including market price multiples of comparable companies, as well as a discounted cash flow (“DCF”) analysis . The Corporation evaluates the results obtained under each valuation methodology to id entify and understand the key value drivers in order to ascertain that the results obtained are reasonable and appropriate under the circumstances. The computations require management to make estimates and assumptions. Critical assumptions that are used as part of these evaluations include: a selection of comparable publicly traded companies, based on size, performance, and asset quality; a selection of comparable and public acquisition transactions of entities of similar size; the discount rate applied to future earnings, based on an estimate of the cost of equity; the potential future earnings of the reporting unit; and the market growth and new business assumptions. For purposes of the market comparable approach, the valuation was determined based on market multiples for comparable companies and recent acquisition transactions and market participant assumptions applied to the reporting unit to derive an implied value of equity. For purposes of the DCF analysi s , the valuation was based on es timated future cash flows. The financial projections used in the DCF analysis for the reporting unit were based on the most recent available data. The growth assumptions included in these projections were based on management’s expectations of the reporting unit’s financial prospects as well as particular plans for the entity ( i.e. , restructuring plans). The cost of equity was estimated using the capital asset pricing model using comparable companies, an equity risk premium, the rate of return of a “riskless ” asset, a size premium based on the size of the reporting unit, and a company specific premium. The resulting discount rate was analyzed in terms of reasonability given current market conditions. The Step 1 evaluation of goodwill allocated to the Florid a reporting unit, under both valuation approaches (market and DCF) indicated that the fair value of the unit was above the carrying amount of its equity book value as of the valuation date (October 1), which meant that Step 2 was not undertaken. Based on t he analysis under both the discounted cash flow and market approaches, the estimated fair val ue of the reporting unit exceeded the carrying amount of the unit, including goodwill, at the evaluation date. The Corporation engaged a third-party valuation sp ecialist to assist management in the annual evaluation of the Florida unit’s goodwill as of the October 1, 201 8 valuation date. In reaching its conclusion on impairment, management discussed with the specialist the methodologies, assumptions, and results s upporting the relevant values for the goodwill and determined that they were reasonable. The goodwill impairment evaluation process requires the Corporation to make estimates and assumptions with regards to the fair value of its reporting unit. Actual va lues may differ significantly from these estimates. Such differences could result in future impairment of goodwill that would, in turn, negatively impact the Corporation’s results of operations and the profitability of the reporting unit where goodwill is recorded. Goodwill was not impaired as of December 31, 201 8 or 201 7. Intangible Assets subject to Amortization - Core deposit intangibles are amortized over their estimated lives, generally on a straight-line basis, and are reviewed periodically for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. The carryi ng value of core deposit intangible assets amounted to $4.3 million as of December 31, 2018 ($5.5 million as of December 31, 2017). In connection with the acquisition of a FirstBank-branded credit card loan portfolio in 2012, the Corporation recognized at acquisition a purchased credit card relationship intangible of $ 24.5 million ($ 5.7 million and $ 8.0 million as of December 31, 201 8 and 201 7 , respectively), which is being amortized on an accelerated basis based on the estimated attrition rate of the purc hased credit card accounts, which reflects the pattern in which the economic benefits of the intangible asset are consumed. These benefits are consumed as the revenue stream generated by the cardholder relationship is realized. For further disclosures, ref er to Note 14 – Goodwill and other Intangibles, to the consolidated financial statements. In the first quarter of 2016, FirstBank Insurance Agency acquired certain insurance customer accounts and related customer records and recognized an insurance custom er relationship intangible of $ 1.1 million ( $0.6 million and $0. 8 million as of December 31, 2018 and 2017, respectively ), which is being amortized on a straight-line basis. The list of accounts acquired has a direct relationship to previous mortgage loan portfolio acquisitions from Doral Bank and Doral Financial in 2015 and 2014, respectively. For intangible assets subject to amortization, an impairment loss is recognized if the carrying value of the intangible asset is not recoverable and exceeds fair va lue. The carrying value of the intangible asset is considered not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use of the asset. The Corporation performed impairment tests for the years ended December 31, 201 8 , 201 7 , and 201 6 and determined that no impairment was needed to be recognized for intangible assets subject to amortization .
Securities purchased and sold under agreements to repurchase [Policy Text Block]	Securities purchased and sold under agreements to repurchase Securities purchased under resale agreements and securities sold u nder repurchase agreements are accounted for as collateralized financing transactions. Generally, these agreements are recorded at the amount at which the securities were purchased or sold. The Corporation monitors the fair value of securities purchased an d sold, and obtains collateral from , or returns it to , the counterparties when appropriate. These financing transactions do not create material credit risk given the collateral provided and the related monitoring process. The Corporation sells and acquires securities under agreements to repurchase or resell the same or similar securities. Generally, similar securities are securities from the same issuer, with identical form and type, similar maturity, identical contractual interest rates, similar assets as collateral, and the same aggregate unpaid principal amount. The counterparty to certain agreements may have the right to repledge the collateral by contract or custom. Such assets are presented separately in the statements of financial condition as securities pledged with creditors ’ right to repledge . Repur chase and resale activities may be transacted under legally enforceable master repurchase agreements that give the Corporation, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Corporation offsets repurchase and resale transactions with the same counterparty on the consolidated statements of financial condition where it has such a legally enforceable master netting agreement and the transactions have th e same maturity date. From time to time, the Corporation modifies repurchase agreements to take advantage of prevailing interest rates. Following applicable GAAP guidance, if the Corporation determines that the debt under the modified terms is substantial ly different from the original terms, the modification must be accounted for as an extinguishment of debt. Modified terms are considered substantially different if the present value of the cash flows under the terms of the new debt instrument is at least 1 0 % different from the present value of the remaining cash flows under the terms of the original instrument. The new debt instrument will be initially recorded at fair value, and that amount will be used to determine the debt extinguishment gain or loss to be recognized through the statement of income and the effective rate of the new instrument. If the Corporation determines that the debt under the modified terms is not substantially different, then the new effective interest rate is determined based on the carrying amount of the original debt instrument. None of the repurchase agreements modified in the past were considered to be substantially different from the original terms, and, therefore, these modifications were not accounted for as extinguishments of debt.
Rewards Liability [Policy Text Block]	Rewards l iability The Corporation offers products, primarily credit cards, that offer various rewards to reward program members, such as airline tickets, cash, or merchandise, based on account activity. The Corporation generally recognizes the cost of rewards as part of business promotion expenses when the rewards are earned by the customer and, at that time, r ecords the corresponding reward liability. The reward liability is computed based on points earned to date that are expected to be redeemed and the average cost per point redemption. The reward liability is reduced as points are redeemed. In estimating t he reward liability, the Corporation considers historical reward redemption behavior, the terms of the current reward program, and the card purchase activity. The reward liability is sensitive to changes in the reward redemption type and redemption rate, w hich is based on the expectation that the vast majority of all points earned will eventually be redeemed. The reward liability, which is included in other liabilities in the consolidated statements of financial condition, totaled $ 7.0 million as of each De cember 31, 201 8 and 201 7 .
Income Tax [PolicyText Block]	Income taxes The Corporation uses the asset and liability method for the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Corporation’s financial statements or tax returns. Deferred income tax assets and liabilities are determined for differences between financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the futur e. The computation is based on enacted tax laws and rates applicable to periods in which the temporary differences are expected to be recovered or settled. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized. In making such assessment, significant weight is given to evidence that can be objectively verified, including both positive and negative evidence. The authoritative guidance for accounting for income taxes requ ires the consideration of all sources of taxable income available to realize the deferred tax asset, including the future reversal of existing temporary differences, tax planning strategies and future taxable income exclusive of the impact of the reversal of temporary differences and carryforwards. In estimating taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, judicial, and regulatory guidance. Refer to Note 26 – Incom e Taxes, to the consolidated financial statements for additional information. Under the authoritative accounting guidance, income tax benefits are recognized and measured based on a two-step analysis: 1) a tax position must be more likely than not to be su stained based solely on its technical merits in order to be recognized; and 2) the benefit is measured at the largest dollar amount of that position that is more likely than not to be sustained upon settlement. The difference between the benefit recognize d in accordance with this analysis and the tax benefit claimed on a tax return is referred to as an Unrecognized Tax Benefit (“UTB”). The Corporation classifies interest and penalties, if any, related to UTBs as components of income tax expense. As of Dec ember 31, 2018 and 2017, the Corporation did not have any UTBs recorded on its books.
Treasury stock [Policy Text Block]	Treasury stock The Corporation accounts for treasury stock at par value. Under this method, the treasury stock account is increased by the par value of each share of common stock reacquired. Any excess paid per share over the par value is debited to additional paid-in capital for the amount per share that was originally credited. Any remaining excess is charged to retained earnings.
Stock-based compensation [Policy Text Block]	Stock-based compensation Compensation cost is recognized in the financial statements for all share-based payment grants. On May 24, 2016, the Corporation’s stockholders approved the amendment and restatement of the First BanCorp. Omnibus Incentive Plan, as amended (the “Omnibus P lan”), 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, restr icted stock, restricted stock units, performance shares, cash-based awards and other stock-based awards. The compensation cost for an award, determined based on the estimate of the fair value at the grant date (considering forfeitures and any post - vesting restrictions), is recognized over the period during which an employee or director is required to provide services in exchange for an award, which is the vesting period. Stock-based compensation accounting guidance provides f o r the develop ment of an estimate of the number of share-based awards that will be forfeited due to employee or director turnover. Quarterly changes in the estimated forfeiture rate may have a significant effect on share-based compensation, as the effect of adjusting the rate for all expense amortization is recognized 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 r esult in a decrease in the expense recognized in the financial statements. If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase in the expense recognized in the financial statements. When unvested shares of restricted stock or performance units are forfeited, any compensation expense previously recognized on the forfeited awards is reversed in the period of the forfeiture. For addi tional information regarding the Corporation’s equity-based compensation and awards granted, refer to Note 21 – Stock-based Compensation, to the consolidated financial statements.
Comprehensive income [Policy Text Block]	Comprehensive income Comprehensive income for First BanCorp. includ es net income and the unrealized gain (loss) on available-for-sale securities, net of estimated tax effects.
Segment Information [Policy Text Block]	Segment i nformation The Corporation reports financial and descriptive information about its reportable segments . Operating segments are componen ts of an enterprise about which separate financial information is available that is evaluated regularly by management in deciding how to allocate resources and in assessing performance. The Corporation’s management determined that the segregation that bes t fulfills the segment definition described above is by 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 December 31, 2018 , the Corporation had six operating segments that are all reportable segments: Commercial and Corporate Banking; Mortgage Banking; Consumer (Retail) Banking; Treasury and Investments; United States Operations; and Virgin Islands Operations. Refer to Note 35 – Segment Informati on, to the consolidated financial statements for additional information.
Valuation of financial instruments [Policy Text Block]	Valuation of financial instruments The measurement of fair value is fundamental to the Corporation’s presentation of its financial condition and results of operations. The Corporati on holds fixed income and equity securities, derivatives, investments, and other financial instruments at fair value. The Corporation holds its investments and liabilities mainly to manage liquidity needs and interest rate risks. A significant part of the Corporation’s total assets is reflected at fair value on the Corporation’s financial statements. The FASB’s 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 classifyi ng financial instruments. The hierarchy is based on whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. Three levels of inputs may be used to measure fair value: Level 1 Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; 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 3 Valuations are observed from unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Under the fair value accounting guidance, an entity has the irrevocable option to elect, on a contract-by-contract basis, to measure certain financial assets and liabilities at fair value at the inception of the contract and, thereafter, to reflect any changes in fair value in current earnings. The Corporation did not make any fair value option election as of December 31, 2018 or 2017. See Note 29 – Fair Value, to the consolidated financial state ments for additional information.
Income recognition- Insurance agencies business [Policy Text Block]	Income recognition— Insurance agency Commission revenue is recognized as of the effective date of the insurance policy. Additional premiums and rate adjustments are recorded as they occur. The Corporation also receiv es contingent commissions from insurance companies as additional incentive for achieving specified premium volume goals and/or the loss experience of the insurance placed by the Corporation. Contingent commissions from insurance companies are recognized wh en determinable, which is generally when such commissions are received or when the amount to be received is reported to the Corporation by the insurance company. An allowance is created for expected adjustments to commissions earned relating to policy canc ellations. Please refer to Note 30 - Revenue from Contracts with Customers, below for additional information about the Corporation’s evaluation of insurance commissions for purposes of the implementation of the revenue recognition accounting guidelines eff ective since January 1, 2018 and other revenues within the scope of the Accounting Standard Codification (“ASC” or “Codification”) Topic 606.
Earnings per common share [Policy Text Block]	Earnings per common share Earnings per share-basic is calculated 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 preferred stock dividends declared, and any cumulative preferred stock 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 excludes unvested shares of restricted stock that do not contain non-forf eitable dividend rights. The computation of diluted earnings per share is similar to the computation of basic earnings per share except that the number of weighted-average common shares is increased to include the number of additional common shares that wo uld have been outstanding if the dilutive common shares had been issued, referred to as potential common shares. Potential dilutive common shares consist of unvested shares of restricted stock that do not contain non-forfeitable dividend rights, perform ance units that do not contain non-forfeitable dividend rights if the performance condition is met as of the end of the reporting period, and warrants outstanding during the period using the treasury stock method. This method assumes that the potential di lutive 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 number o f 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 and performance units that do not contain non- forfeitable dividend rights, and warrants 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 th eir inclusion would have an antidilutive effect on earnings per share.

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

Evidence used to determinate the partial reversal of valuation allowance	The positive evidence considered by management in arriving at its conclusion to reverse part of the deferred tax asset valuation allowance includes factors such as: FirstBank’s three-year cumulative income position; the continued profitability following the hurricane events in 2017; and forecasts of future profitability, under several potential scenarios, that support significant utilization of NOLs prior to their expiration ranging between the years 2021 through 2024. The negative evidence considered by management includes: uncertainties around the state of the Puerto Rico economy, including the effect of hurricane recovery funds together with Puerto Rico government debt renegotiation efforts and the ultimate sustainability of the approved Fiscal Plan; and consideration of the Corporation’s still elevated levels of non-performing assets.
