Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The Consolidated Financial Statements (unaudited) of First BanCorp. (the “Corporation”) have been prepared in conformity with the accounting policies stated in the Corporation’s Audited Consolidated Financial Statements included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Annual Report on Form 10-K”). Certain information and note disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted from these statements pursuant to the rules and regulations of the SEC and, accordingly, these financial statements should be read in conjunction with the Audited Consolidated Financial Statements of the Corporation for the year ended December 31, 2018, which are included in the 2018 Annual Report on Form 10-K. All adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the statement of financial position, results of operations and cash flows for the interim periods have been reflected. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the quarter and six-month period ended June 30, 2019 are not necessarily indicative of the results to be expected for the entire year. Adoption of New Accounting Requirements and Recently Issued but Not Yet Effective Accounting Requirements The Financial Accounting Standards Board (“FASB”) has issued the following accounting pronouncements and guidance relevant to the Corporation’s operations: Lease Accounting In February 2016, the FASB updated the FASB Accounting Standards Codification (“ASC” or the “Codification”) to replace ASC Topic 840, “Leases (Topic 840)” (“ASC Topic 840”), with new guidance for the financial reporting about leasing transactions. Under the new guidance, a lessee is required to recognize a right-of-use asset (“ROU”) and a lease liability for leases with lease terms of more than 12 months. Similar with the practice before the adoption of this guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily depend on its classification as a finance or operating lease. However, unlike previous guidance, which required the recognition of only capital leases on the balance sheet, the guidance requires both types of leases to be recognized on the balance sheet. The guidance also requires disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative information and additional information about the amounts recorded in the financial statements. The FASB issued an update in January 2018 providing an optional transition practical expedient under which an entity need not evaluate under new ASC Topic 842, “Leases” (“ASC Topic 842”), land easements that existed or expired before the entity’s adoption of ASC Topic 842 and were not previously accounted for as leases. In addition, the FASB issued an update in July 2018 that provides entities with an additional and optional transition method that allows entities to adopt the new standard prospectively as of the effective date, without adjusting comparative periods presented. Also, the amendments provide lessors with a practical expedient, by class of underlying asset, to not separate non lease components, subject to certain circumstances. Also in July 2018, the FASB issued an update that makes various technical corrections to clarify how to apply certain aspects of the new leases standard, such as reassessment of lease classification, variable lease payments that depend on an index or a rate, lease term and purchase options, and certain transition adjustments, among others. The guidance on leases took effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The update affected the Corporation’s consolidated financial statements since the Corporation has operating and lease arrangements for which it is a lessee. The new standard provides a number of optional practical expedients in transition. The Corporation adopted this guidance in 2019, and elected the optional transition approach to not apply the new lease standard in comparative periods presented and the package of practical expedients, which allows the Corporation not to reassess prior conclusions about lease classification and initial direct costs. The adoption of this standard in January 2019 resulted in the recognition of ROU assets and lease liabilities for operating leases of $ 59.6 million and $ 62.1 million, respectively, with the most significant impact from recognition of ROU assets and liabilities related to the operating leases for the Bank’s branches and automated teller machines (“ATMs”). The Corporation elected not to recognize ROU assets and lease liabilities that arise from short-term leases, primarily related to certain month-to-month ATM operating leases. Disclosures required by the standard have been included in Note 11 - Leases. Amortization of Premiums and Discounts on Callable Debt Securities In March 2017, the FASB updated the Codification to shorten the amortization period for certain purchased callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. With respect to securities held at a discount, the amendments do not require an accounting change; thus, the discount continues to be amortized to maturity. The amendments in this update more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. In most cases, market participants price securities to the call date that produces the worst yield when the coupon is above current market rates (that is, the security is trading at a premium) and price securities to maturity when the coupon is below market rates (that is, the security is trading at a discount) in anticipation that the borrower will act in its economic best interest. As a result, the amendments more closely align interest income recorded on bonds held at a premium or a discount with the economics of the underlying instrument. For public business entities, the amendments in this update took effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this guidance during the first quarter of 2019, did not have a material effect on the Corporation’s consolidated statement of financial condition or results of operations. As of June 30, 2019, the Corporation does not have callable debt securities held at a premium. Derivatives and Hedging In August 2017, the FASB updated the Codification to: (i) expand hedge accounting for nonfinancial and financial risk components and amend measurement methodologies to more closely align hedge accounting with a company’s risk management activities; (ii) decrease the complexity of preparing and understanding hedge results by eliminating the separate measurement and reporting of hedge ineffectiveness; (iii) enhance transparency, comparability, and understanding of hedge results through enhanced disclosures and a change in the presentation of hedge results to align the effects of the hedging instrument and the hedged item; and (iv) reduce the cost and complexity of applying hedge accounting by simplifying the manner in which assessments of hedge effectiveness may be performed. This update took effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance requires companies to apply requirements to existing hedging relationships on the date of adoption, and the effect of the adoption should be reflected as of the beginning of the fiscal year of adoption. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 815, Derivative and Hedging,” to provide further clarification on previously issued updates. This Update addresses the following areas of the guidance: (i) partial-term fair value hedges; (ii) fair value hedge basis adjustments; (iii) not-for-profit entities and private companies; and (v) first-payments-received cash flow hedging. As June 30, 2019, all of the derivatives held by the Corporation were considered economic undesignated hedges. The adoption of this guidance during the first quarter of 2019 did not have an effect on the Corporation’s consolidated statement of financial condition or results of operations. Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income In February 2018, the FASB updated the Codification to provide entities with an option to reclassify to retained earnings, tax effects that were stranded in accumulated other comprehensive income, pursuant to the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). This guidance took effect for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This guidance could be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the corporate tax rate in the Tax Act is recognized. The adoption of this guidance during the first quarter of 2019 did not have an effect on the Corporation’s consolidated financial statements. Accounting for Financial Instruments – Credit Losses In June 2016, the FASB updated the Codification to introduce new guidance for the accounting for credit losses. The guidance includes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The CECL model will apply to: (1) financial assets subject to credit losses and measured at amortized cost; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (“ECL”) should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating ECL. The guidance does not prescribe a specific method to make the estimate, so its application will require significant judgment. Generally, upon initial recognition of a financial asset, the estimate of the ECL will be recorded through an allowance for credit losses (“ACL”) with an offset to current earnings. Subsequently, the ECL will need to be reassessed each period, and both negative and positive changes to the estimate will be recognized through an adjustment to the allowance for loan and lease losses and earnings. The guidance amends the current OTTI model for available-for-sale debt securities. The new available-for-sale debt security model will require an estimate of ECL only when the fair value is below the amortized cost of the asset. The length of time the fair value of an available-for-sale debt security has been below the amortized cost will no longer affect the determination of whether a credit loss exists. As such, the new available-for-sale debt security model is not an OTTI model. In addition, credit losses on available-for-sale debt securities will now be limited to the difference between the security’s amortized cost basis and its fair value. The available-for-sale debt security model will also require the use of an allowance to record ECL (and subsequent recoveries). The purchased financial assets with credit deterioration (“PCD”) model will apply to purchased financial assets (measured at amortized cost or available-for-sale) that have experienced more than insignificant credit deterioration since origination. This represents a change from the scope of what are considered purchased credit-impaired assets under today’s model. In contrast to the accounting for originated or purchased assets that do not qualify as PCD, the initial estimate of ECL for a PCD will be recognized through an allowance for loan and lease losses with an offset to the cost basis of the related financial asset at acquisition ( i.e. , there will be no effect on net income at initial recognition). Subsequently, the accounting will follow the applicable CECL or available-for-sale debt security impairment model with all adjustments of the allowance for loan and lease losses recognized through earnings. Beneficial interests classified as held-to-maturity or available-for-sale will need to apply the PCD model if the beneficial interest meets the definition of PCD or if there is a significant difference between contractual and expected cash flows at initial recognition. In general, the new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. However, prospective application is required for PCD assets previously accounted for under ASC Topic 310-30, “Receivables,” and for debt securities for which an OTTI was recognized prior to the date of adoption. This guidance also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, public business entities will need to disclose, among other things, the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination ( i.e. , by vintage year). In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments- Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” in part to clarify the accounting treatment for the measurement of credit losses under ASC 326, “Financial Instruments.” This update provides clarification on the following areas of the guidance: (i) accrued interest; (ii) recoveries; (iii) projections of the interest rate environment; (iv) consideration of prepayments; and (v) other topics. In May 2019, the FASB issued an update that allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that: (i) were previously recorded at amortized cost and (ii) are within the scope of ASC Topic 326-20, “Financial Instruments – Credit Losses Measured at Amortized Cost,” if the instruments are eligible for the fair value option under ASC Topic 825-10, “Financial Instruments-Overall.” The guidance will be effective for public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption of the guidance is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Corporation developed a project plan in order to comply on a timely basis with the implementation of this new CECL impairment model and expects to adopt the guidance in the first quarter of 2020. The implementation process is being conducted by a working group composed of members from multiple areas across the Corporation and includes the selection and development of loss forecasting models, evaluation of technical accounting topics, updates to the Corporation’s allowance documentation, reporting processes and related internal controls, and evaluation of the overall operational readiness for the adoption. This process is expected to continue for the reminder of 2019. Currently, the Corporation is in the process of conducting and validating the results of parallel runs pursuant to the provisions of the CECL standard alongside the Corporation’s current processes for estimation of the allowance for loan and leases losses. The Corporation’s approach for estimating ECL for applicable loans and debt securities includes the following key components:  An initial forecast period (“reasonable and supportable period”) between 2 and 4 years, varying by portfolio geographies, for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectations of losses based on forward-looking economic scenarios over that time.  A historical loss forecast period covering the remaining contractual life, adjusted for prepayments, by portfolio segments and classes of financing receivables based on the change in key historic economic variables during representative historical expansionary and recessionary periods.  A reversion period connecting the initial loss estimate covered by the reasonable and supportable period to historical loss forecast based on economic conditions at measurement date.  The Corporation will utilize discounted cash flow (“DCF”) methods to measure credit impairment for loans modified in a TDR, unless they are collateral dependent and measured based on the fair value of the collateral. The DCF methods would provide the estimated life-time credit losses.  For available-for-sale and held-to-maturity securities, the Corporation will utilize the DCF methods to measure the allowance for credit losses. The Corporation expects an overall increase in the ACL, with a higher increase for longer duration residential mortgage loan portfolios. We will recognize an ACL for available-for-sale and held-to-maturity securities. The ACL on available-for-sale securities will be subject to a limitation based on the fair value of the security. We continue to evaluate the results of modeled loss estimates and continue to conduct refinements to the approach, including considerations around imprecision and uncertainty, based on management’s judgment on the inherent risks around processes and assumptions in estimating the ACL. The amount of the change in the ACL will be impacted by the Corporation’s loan portfolio and debt securities mix, credit quality, economic conditions and forecasts at the adoption date. The Corporation expects to have a cumulative-effect adjustment to retained earnings for the change in the ACL, which will impact capital. An increase in the ACL will result in a reduction to the Corporation’s and banking subsidiary regulatory capital ratios, however, as of this date, we are not able to provide a precise estimate of the impact. Banking regulatory agencies have permitted institutions to limit the initial regulatory capital day-one impact by allowing a three-year phase in period for this impact, on a straight-line basis. The working group provides periodic updates to the Corporation’s CECL Management Committee, which has oversight responsibilities for the implementation efforts. The CECL Management Committee also reports to the Corporation’s Board of Directors Audit Committee progress of the implementation plan. Subsequent Measurement of Goodwill In January 2017, the FASB updated the Codification to simplify the subsequent measurement of goodwill by eliminating Step 2 from the current two-step goodwill impairment test. This guidance provides that a goodwill impairment test shall be conducted by comparing the fair value of a reporting unit with its carrying amount. Entities must recognize an impairment charge for goodwill equal to the excess of the carrying amount over the reporting unit’s fair value. Entities have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The effect of this guidance will depend upon the performance of the reporting units that have goodwill and the market conditions affecting the fair value of each reporting unit going forward. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB updated the Codification and amended ASC Topic 820, “Fair Value Measurement and Disclosures,” to add, remove, and modify fair value measurement disclosure requirements. The disclosure requirements that are removed for public entities include: (i) transfers between Level 1 and Level 2 of the fair value hierarchy; (ii) the policy for determining when transfers between any of the three levels have occurred; and (iii) the valuation processes used for Level 3 measurements. The disclosure requirements that are modified for public entities include: (i) for certain investments in entities that calculate the net asset value, revisions to require disclosures about the timing of liquidation and lapses of redemption restrictions, if the latter has been communicated to the reporting entity; and (ii) revisions to clarify that the disclosure of Level 3 measurement uncertainty should communicate information about the uncertainty as of the balance sheet date. The additional or new disclosure requirements include: (i) the changes in unrealized gains and losses for the period must be included in other comprehensive income for recurring Level 3 instruments held as of the balance sheet date; and (ii) the range and weighted average of significant unobservable inputs used for Level 3 measurements must be disclosed, but an entity has the option to disclose other quantitative information in place of the weighted average to the extent that it would be a more reasonable and rational method to reflect the distribution of certain unobservable inputs. This update is effective for all entities in fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any of the removed or modified disclosures immediately even if adoption of the new disclosures is delayed until the effective date. In the third quarter of 2018, the Corporation early adopted the disclosure requirements that were removed or modified by this guidance. Collaborative Arrangements In November 2018, the FASB issued new guidance to clarify the interaction between Collaborative Arrangements (“ASC Topic 808”) and Revenue from Contracts with Customers (“ASC Topic 606”) standards. The guidance (i) clarifies that certain transactions between collaborative arrangement participants should be accounted for under the ASC Topic 606 guidance; (ii) adds unit of account guidance to ASC Topic 808 to align with ASC Topic 606; and (iii) clarifies presentation guidance for transactions with a collaborative arrangement participant that is not accounted for under ASC Topic 606. The guidance is effective for annual reporting periods beginning after December 1, 2019, including interim reporting periods within these annual reporting periods, with early adoption permitted. The Corporation does not expect the adoption of this standard to have a material effect on its consolidated financial statements.

Update On Effects Of Natural Disasters [Abstract]
Natural Disasters [Text Block]	NOTE 2 – UPDATE ON EFFECTS OF NATURAL DISASTERS Two strong hurricanes affected the Corporation’s service areas during September 2017. The following summarizes the more significant continuing 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 first quarter of 2019, the Corporation recorded a loan loss reserve release of approximately $ 6.4 million in connection with revised estimates associated with the effects of the hurricanes. The revised estimates were primarily attributable to updated payment patterns and probability of default credit risk analyses applied to consumer borrowers, and updated assessments of financial performance and repayment prospects of certain individually-assessed commercial credits. The significant overall uncertainties in the early assessments of hurricane-related credit losses have been largely addressed in the 18-month period after the hurricanes, and the hurricanes’ effect on credit quality is now reflected in the normal process for determining the allowance for loan and lease losses and not through a separate hurricane-related qualitative reserve. Some uncertainties remain, however, including the resolution of insurance claims for certain individual customers. Casualty Losses and Related Insurance The Corporation incurred a variety of costs to operate in disaster response mode, and some facilities and their contents, including certain OREO properties, were damaged by the hurricanes. 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 the second quarter of 2019, the Corporation reached settlement on certain claims arising from the hurricanes. As a result, the Corporation received insurance proceeds of approximately $ 1.5 million, primarily involving repairs and maintenance costs, and impairments related to facilities in the British Virgin Islands. The insurance proceeds were recorded against incurred losses or previously-established accounts receivable. Insurance recoveries are recorded in the same income statement caption as the incurred losses. Recoveries from insurance proceeds in excess of losses incurred, amounting to $ 0.6 million for the second quarter of 2019, were recognized as a gain from insurance proceeds and reported as part of “Other non-interest income” in the consolidated statements of income. As of June 30, 2019, the Corporation had an insurance claim receivable of $ 1.5 million (December 31, 2018 - $ 3.4 million), which is included as part of “Other assets” in the consolidated statements of financial condition. Management also believes that there is a possibility that some gains will be recognized with respect to casualty and lost revenue claims in future periods, but this is contingent on reaching agreements on the Corporation’s claims with the insurance carriers. During the first quarter of 2019, the Corporation recorded a $ 2.3 million credit against employees’ compensation and benefits expenses related to an employee retention benefit payment (the “Benefit”) received by the Corporation by virtue of the Disaster Tax Relief and Airport Extension Act of 2017, as amended (the “Act”). The Benefit was available to eligible employers affected by Hurricanes Irma and Maria. An eligible employer, as established in the Internal Revenue Circular Letter No. 18-11 issued by the Puerto Rico Department of Treasury, is an employer that (i) on September 16, 2017 (or September 4, 2017 for Hurricane Irma) was engaged in a trade or business in Puerto Rico; (ii) whose business became inoperable on any day after such date and before January 1, 2018, due to damage caused by Hurricane Irma or Maria; and (iii) continued to pay wages to its eligible employees during the period in which the business was inoperable. For purposes of the income tax return, the Benefit will not affect the Corporation’s right to claim a deduction on wages paid and the amount of the Benefit will not be treated as taxable income.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	NOTE 3 – EARNINGS PER COMMON SHARE The calculations of earnings per common share for the quarters and six-month periods ended June 30, 2019 and 2018 are as follows: Quarter Ended Six-Month Period Ended June 30, June 30, 2019 2018 2019 2018 (In thousands, except per share information) Net income $ 41,287 $ 31,032 $ 84,601 $ 64,180 Less: Preferred stock dividends ( 669) ( 669) ( 1,338) ( 1,338) Net income attributable to common stockholders $ 40,618 $ 30,363 $ 83,263 $ 62,842 Weighted-Average Shares: Average common shares outstanding 216,674 215,737 216,507 215,194 Average potential dilutive common shares 304 929 458 1,289 Average common shares outstanding - assuming dilution 216,978 216,666 216,965 216,483 Earnings per common share: Basic $ 0.19 $ 0.14 $ 0.38 $ 0.29 Diluted $ 0.19 $ 0.14 $ 0.38 $ 0.29 Earnings per common share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares issued and outstanding. Net income attributable to common stockholders represents net income adjusted for any preferred stock dividends, including any dividends declared, and any cumulative dividends related to the current dividend period that have not been declared as of the end of the period. Basic weighted-average common shares outstanding exclude unvested shares of restricted stock that do not contain non-forfeitable dividend rights. Potential dilutive common shares consist of unvested shares of restricted stock that do not contain non-forfeitable dividend rights, warrants outstanding during the period and common stock issued under the assumed exercise of stock options using the treasury stock method. This method assumes that the potential dilutive common shares are issued and outstanding and the proceeds from the exercise, in addition to the amount of compensation cost attributable to future services, are used to purchase common stock at the exercise date. The difference between the numbers of potential dilutive shares issued and the shares purchased is added as incremental shares to the actual number of shares outstanding to compute diluted earnings per share. Potential dilutive common shares also include performance units that do not contain non-forfeitable dividend rights if the performance condition is met as of the end of the reporting period. Unvested shares of restricted stock, 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. On May 17, 2018, the U.S. Treasury exercised its warrant to purchase 1,285,899 shares of the Corporation’s common stock on a cashless basis, resulting in the issuance of 730,571 shares of common stock.

STOCK-BASED COMPENSATION

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	NOTE 4 – STOCK-BASED COMPENSATION . On May 24, 2016, the Corporation’s stockholders approved the amendment and restatement of the First BanCorp. Omnibus Incentive Plan, as amended (the “Omnibus Plan”), to, among other things, increase the number of shares of common stock reserved for issuance under the Omnibus Plan, extend the term of the Omnibus Plan to May 24, 2026 and re-approve the material terms of the performance goals under the Omnibus Plan for purposes of the then-effective Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended. The Omnibus Plan provides for equity-based compensation incentives (the “awards”) through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, cash-based awards and other stock-based awards. The Omnibus Plan authorizes the issuance of up to 14,169,807 shares of common stock, subject to adjustments for stock splits, reorganizations and other similar events. As of June 30, 2019, 6,633,989 authorized shares of common stock were available for issuance under the Omnibus Plan. The Corporation’s Board of Directors, based on the recommendation of the Corporation’s Compensation and Benefits Committee, has the power and authority to determine those eligible to receive awards and to establish the terms and conditions of any awards, subject to various limits and vesting restrictions that apply to individual and aggregate awards. Restricted Stock Under the Omnibus Plan, the Corporation may grant restricted stock to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While the restricted stock is subject to forfeiture and does not contain non-forfeitable dividend rights, restricted stock participants may exercise full voting rights. The restricted stock granted under the Omnibus Plan is typically subject to a vesting period. During the first six months of 2019, the Corporation awarded to its independent directors 3,745 shares of restricted stock that are subject to a one year vesting period. In addition, during the first six months of 2019, the Corporation awarded 262,371 shares of restricted stock to employees; fifty percent ( 50%) of those shares vest on the two-year anniversary of the grant date and the remaining 50% vest on the three-year anniversary of the grant date. Included in those 262,371 shares of restricted stock granted during the first six months of 2019 were 13,308 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 the first six months of 2019 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 the first six months of 2019 under the Omnibus Plan: Six-Month Period Ended June 30, 2019 Number of shares Weighted-Average of restricted Grant Date stock Fair Value Unvested shares outstanding at beginning of year 964,110 $ 4.79 Granted 266,116 11.15 Forfeited ( 2,250) 7.91 Vested ( 548,569) 3.41 Unvested shares outstanding as of June 30, 2019 679,407 $ 8.39 For the quarter and six-month period ended June 30, 2019, the Corporation recognized $ 0.7 million and $ 1.6 million, respectively, of stock-based compensation expense related to restricted stock awards, compared to $ 0.8 million and $ 1.9 million for the same periods in 2018, respectively. As of June 30, 2019, there was $ 3.5 million of total unrecognized compensation cost related to unvested shares of restricted stock. The weighted average period over which the Corporation expects to recognize such cost is 1.9 years. During the first six months of 2018, the Corporation awarded 342,439 shares of restricted stock to employees; 50% of those shares vest on the two-year anniversary of the grant date and the remaining 50% vest on the three-year anniversary of the grant date. Included in those 342,439 shares of restricted stock were 20,447 shares granted to retirement-eligible employees at the grant date. Stock-based compensation accounting guidance requires the Corporation to reverse compensation expense for any awards that are forfeited due to employee or director turnover. Quarterly changes in the estimated forfeiture rate may have a significant effect on stock-based compensation, as the 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 result in a decrease in the expense recognized in the financial statements. If the actual forfeiture rate is lower than the estimated forfeiture rate, an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase in the expense recognized in the financial statements. Performance Units Under the Omnibus Plan, the Corporation may award performance units to Omnibus Plan participants. During the first six months of 2019, the Corporation granted 200,053 units to executives, with each unit representing the value of one share of the Corporation’s common stock. The performance units granted in 2019 are for the performance period beginning January 1, 2019 and ending on December 31, 2021 and are subject to 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. The performance units will vest based on the achievement of a pre-established tangible book value per share target as of December 31, 2021. 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. During the first six months of 2018, the Corporation awarded 304,408 performance units to executives. The performance units granted in 2018 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 and a pre-established performance target level as described above. The fair value of the performance units awarded during the first six months of 2019 and 2018 was based on the market price of the Corporation’s outstanding common stock on the date of the grant. For the quarter and six-month period ended June 30, 2019, the Corporation recognized $ 0.3 million and $ 0.5 million, respectively, of stock-based compensation expense related to performance units awards, compared to $ 0.1 million and $ 0.3 million for the same periods in 2018, respectively. As of June 30, 2019, there was $ 3.0 million of total unrecognized compensation cost related to unvested performance units that the Corporation expects to recognize over the next three years. The total amount of compensation expense recognized reflects management’s assessment of the probability that the pre-established performance goal will be achieved. 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 of the Corporation’s common stock issued under the Omnibus Plan, instead of cash. During the first six months of 2018, the Corporation issued 268,709 shares of common stock with a weighted average market value per share of $ 6.51 as salary stock compensation. This resulted in compensation expense of $ 1.7 million recorded in the first six month of 2018. Effective July 1, 2018, the Corporation ceased paying additional salary amounts in the form of stock in accordance with the previously disclosed revised executive compensation program. During the first six months of 2019, the Corporation withheld 170,827 shares (first six months of 2018 – 328,433 shares) of the restricted stock that vested during such period and withheld 96,377 shares from the common stock paid to certain senior officer as additional compensation in the first six months of 2018 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.

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 following tables show the Corporation’s available-for-sale investments’ fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of June 30, 2019 and December 31, 2018. 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 credit loss was charged against the amortized cost basis of the debt security.

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 basis. The Corporation considered the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:  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 principal or interest payments, any 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. No The following tables summarize the roll-forward of credit losses on debt securities held by the Corporation for which a portion of an OTTI was also recognized in OCI as of the indicated dates: Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments March 31, recognized in earnings on June 30, 2019 securities that have been 2019 Balance previously impaired Balance (In thousands) Available-for-sale securities Private label MBS $ 6,842 $ - $ 6,842 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments December 31, recognized in earnings on June 30, 2018 securities that have been 2019 Balance previously impaired Balance (In thousands) Available-for-sale securities Private label MBS $ 6,842 $ - $ 6,842 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments March 31, recognized in earnings June 30, 2018 on securities that have been 2018 Balance previously impaired Balance (In thousands) Available-for-sale securities Private label MBS $ 6,792 $ - $ 6,792 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments December 31, recognized in earnings June 30, 2017 on securities that have been 2018 Balance previously impaired Balance (In thousands) Available-for-sale securities Private label MBS $ 6,792 $ - $ 6,792 As of June 30, 2019, the Corporation’s available-for-sale investment securities portfolio included bonds of the Puerto Rico Housing Finance Authority (“PRHFA”) at an amortized cost of $ 8.3 million (fair value - $ 7.0 million). Approximately $ 4.3 million (fair value - $ 2.9 million) of these bonds consist of a residential pass-through MBS issued by the PRHFA that is collateralized by certain second mortgages originated under a program launched by the Puerto Rico government in 2010. This bond was structured as a zero-coupon bond for the first ten years (up to July 2019). The underlying source of payment is second mortgage loans in Puerto Rico, not the central government, but PRHFA provides a guarantee in the event of default and subsequent foreclosure of the underlying property. Based on the quarterly analyses performed, management concluded that these obligations were not other-than-temporarily impaired as of June 30, 2019. A deterioration of the Puerto Rico economy or fiscal health of the PRHFA could further impact the value of these securities, resulting in losses to the Corporation. The Corporation does not have the intent to sell these debt securities prior to recovery of the amortized cost basis. The Corporation performed an OTTI assessment on its private label MBS, which are collateralized by fixed-rate mortgages on single-family residential properties 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 FICO scores (over 700) and moderate loan-to-value ratios (under 80%), as well as moderate delinquency levels. Based on the expected cash flows, and since the Corporation does not have the intention to sell the securities and has sufficient capital and liquidity to hold these securities until a recovery of the fair value occurs, only the credit loss component, if any, is reflected in earnings. Significant assumptions in the valuation of the private label MBS were as follows: As of As of June 30, 2019 December 31, 2018 Weighted Range Weighted Range Average Minimum Maximum Average Minimum Maximum Discount rate 13.8% 13.8% 13.8% 14.5% 14.5% 14.5% Prepayment rate 9.1% 3.3% 17.0% 11.4% 3.3% 20.9% Projected Cumulative Loss Rate 3.1% 0.0% 6.6% 3% 0.0% 6.8% Investments Held to Maturity The amortized cost, gross unrecognized gains and losses, estimated fair value, weighted-average yield and contractual maturities of investment securities held to maturity as of June 30, 2019 and December 31, 2018 were as follows: June 30, 2019 Amortized cost Fair value Gross Unrecognized (Dollars in thousands) gains losses Weighted- average yield% Puerto Rico Municipal Bonds: After 1 to 5 years $ 5,957 $ - $ 402 $ 5,555 4.96 After 5 to 10 years 53,016 - 5,684 47,332 6.11 After 10 years 85,699 - 15,472 70,227 6.03 Total investment securities held to maturity $ 144,672 $ - $ 21,558 $ 123,114 6.02 December 31, 2018 Amortized cost Fair value Gross Unrecognized (Dollars in thousands) gains losses Weighted- average yield% Puerto Rico Municipal Bonds: After 1 to 5 years $ 6,100 $ - $ 435 $ 5,665 4.79 After 5 to 10 years 53,016 - 5,360 47,656 6.00 After 10 years 85,699 - 13,362 72,337 5.86 Total investment securities held to maturity $ 144,815 $ - $ 19,157 $ 125,658 5.86 The following tables show the Corporation’s held-to-maturity investments’ fair value and gross unrecognized losses, aggregated by investment category and length of time that individual securities had been in a continuous unrecognized loss position, as of June 30, 2019 and December 31, 2018: As of June 30, 2019 Less than 12 months 12 months or more Total Unrecognized Unrecognized Unrecognized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 123,114 $ 21,558 $ 123,114 $ 21,558 As of December 31, 2018 Less than 12 months 12 months or more Total Unrecognized Unrecognized Unrecognized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 125,658 $ 19,157 $ 125,658 $ 19,157 The Corporation determines the fair market value of Puerto Rico Municipal Bonds based on a discounted cash flow analysis using risk-adjusted discount rates. 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 the 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 were performing and current as to scheduled contractual payments as of June 30, 2019. Approximately 70% of the held-to-maturity municipal bonds were issued by three of the largest municipalities in Puerto Rico. The vast majority of revenues of these three municipalities is independent of the Puerto Rico central government. These obligations typically are not issued in bearer form, nor are they registered with the SEC, and are not rated by external credit agencies. In most cases, these bonds have priority over the payment of operating costs and expenses of the municipality, which are required by law to levy special property taxes in such amounts as are required for the payment of all of their respective general obligation bonds and loans. The Corporation performs periodic credit quality 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 June 30, 2019. During the second quarter of 2019, the PROMESA oversight board announced the designation of the Puerto Rico’s 78 municipalities as covered instrumentalities under PROMESA. Meanwhile, the latest fiscal plan certified by the PROMESA oversight board did not contemplate a restructuring of the debt of Puerto Rico’s municipalities, but the plan did call for the gradual elimination of budgetary subsidies provided to municipalities by the central government. Furthermore, municipalities are also likely to be affected by the negative economic and other effects resulting from expense, revenue or cash management measures taken by the Puerto Rico government to address its fiscal and liquidity shortfalls, or measures included in fiscal plans of other government entities, such as the fiscal plans of the Government Development Bank for Puerto Rico (“GDB”) and the Puerto Rico Electric Power Authority (“PREPA”). 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 relating to these securities will be required. From time to time, the Corporation has securities held to maturity with an original maturity of three months or less that are considered cash and cash equivalents and are classified as money market investments in the consolidated statements of financial condition. As of June 30, 2019 and December 31, 2018, the Corporation had no outstanding securities held to maturity that were classified as cash and cash equivalents.

Loans held for investment on which accrual of interest income had been discontinued were as follows: As of As of June 30, December 31, (In thousands) 2019 2018 Nonaccrual loans: Residential mortgage $ 129,501 $ 147,287 Commercial mortgage 77,495 109,536 Commercial and Industrial 21,327 30,382 Construction: Land 5,599 6,260 Construction-residential 1,337 2,102 Consumer: Auto loans 10,361 11,212 Finance leases 994 1,329 Other consumer loans 6,491 7,865 Total nonaccrual loans held for investment (1)(2)(3) $ 253,105 $ 315,973 Excludes $ 7.1 million and $ 16.1 million of nonaccrual loans held for sale as of June 30, 2019 and December 31, 2018, respectively. Amount excludes purchased-credit impaired (“PCI”) loans with a carrying value of approximately $ 141.7 million and $ 146.6 million as of June 30, 2019 and December 31, 2018, respectively, primarily mortgage loans acquired from Doral Bank in the first quarter of 2015 and from Doral Financial in the second quarter of 2014, as further discussed below. These loans are not considered nonaccrual due to the application of the accretion method, under which these loans will accrete interest income over the remaining life of the loans using an estimated cash flow analysis. Nonaccrual loans exclude $ 482.0 million and $ 478.9 million of Troubled Debt Restructuring (“TDR”) loans that were in compliance with modified terms and in accrual status as of June 30, 2019 and December 31, 2018, respectively. As of June 30, 2019, the recorded investment of residential mortgage loans collateralized by residential real estate property that were in the process of foreclosure amounted to $ 159.2 million, including $ 41.0 million of loans insured by the U.S. Federal Housing Administration (“FHA”) or guaranteed by the U.S. Veterans Administration (“VA”), and $ 18.4 million of PCI loans. The Corporation commences the foreclosure process on residential real estate loans when a borrower becomes 120 days delinquent in accordance with the guidelines of the Consumer Financial Protection Bureau (“CFPB”). Foreclosure procedures and timelines vary depending on whether the property is located in a judicial or non-judicial state. Judicial states ( i.e. , Puerto Rico, Florida and the USVI) require the foreclosure to be processed through the state’s court while foreclosure in non-judicial states ( i.e. , the BVI) is processed without court intervention. Foreclosure timelines vary according to local jurisdiction law and investor guidelines. Occasionally, foreclosures may be delayed due to, among other reasons, mandatory mediations, bankruptcy, court delays and title issues.

The Corporation considers a loan as a criticized asset if its risk rating is Special Mention, Substandard, Doubtful or Loss. These categories are defined as follows: Special Mention – A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Corporation’s credit position at some future date. Special Mention assets are not adversely classified and do not expose the Corporation sufficient risk to warrant adverse classification. Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Doubtful classifications have all of the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions and values. A Doubtful classification may be appropriate in cases where significant risk exposures are perceived, but loss cannot be determined because of specific reasonable pending factors, which may strengthen the credit in the near term. Loss – Assets classified Loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this asset even though partial recovery may occur in the future. There is little or no prospect for near term improvement and no realistic strengthening action of significance pending. The Corporation periodically reviews its loan classifications to evaluate if they are properly classified, and to determine impairment, if any. The frequency of these reviews will depend on the amount of the aggregate outstanding debt, and the risk rating classification of the obligor. In addition, during the renewal and annual review process of applicable 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 performs 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 evaluation 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 effectiveness of the credit management process and the identification of any deficiency that may arise in the credit-granting process. Based on its findings, the Loan Review Group recommends corrective actions, if necessary, that help in maintaining a sound credit process. The Loan Review Group reports the results of the credit process reviews to the Risk Management Committee of the Corporation’s Board of Directors. The Corporation’s consumer and residential loans credit quality indicators as of June 30, 2019 and December 31, 2018 are summarized below: Consumer Credit Exposure - Credit Risk Profile Based on Payment Activity Residential Real Estate Consumer June 30, 2019 FHA/VA/ Guaranteed (1) Other residential loans Auto Finance Leases Other Consumer (In thousands) Performing $ 132,900 $ 2,669,978 $ 1,024,735 $ 369,913 $ 700,422 Purchased Credit-Impaired (2) - 138,367 - - - Nonaccrual - 129,501 10,361 994 6,491 Total $ 132,900 $ 2,937,846 $ 1,035,096 $ 370,907 $ 706,913 Consumer Credit Exposure - Credit Risk Profile Based on Payment Activity Residential Real Estate Consumer December 31, 2018 FHA/VA/ Guaranteed (1) Other residential loans Auto Finance Leases Other Consumer (In thousands) Performing $ 147,205 $ 2,725,540 $ 935,264 $ 332,207 $ 656,836 Purchased Credit-Impaired (2) - 143,176 - - - Nonaccrual - 147,287 11,212 1,329 7,865 Total $ 147,205 $ 3,016,003 $ 946,476 $ 333,536 $ 664,701 It is the Corporation's policy to report delinquent residential mortgage loans insured by the FHA, guaranteed by the VA, and other government-insured loans as 90 days past-due loans and still accruing as opposed to nonaccrual loans since the principal repayment is insured.

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 Rico branches of Doral Bank, acquired certain assets, including PCI loans, and assumed deposits, through an alliance with Banco Popular of Puerto Rico, which was the successful lead bidder with the FDIC on the failed Doral Bank, as well as other co-bidders. 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 from Doral Financial in the second quarter of 2014 of all its rights, title and interest in first and second residential mortgage loans in full satisfaction of secured borrowings owed by such entity to FirstBank. Under ASC Topic 310-30, the acquired PCI loans 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 nonaccrual 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 recognizes 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. The carrying amounts of PCI loans were as follows: As of June 30, December 31, 2019 2018 (In thousands) Residential mortgage loans $ 138,367 $ 143,176 Commercial mortgage loans 3,339 3,464 Total PCI loans $ 141,706 $ 146,640 Allowance for loan losses ( 11,434) ( 11,354) Total PCI loans, net of allowance for loan losses $ 130,272 $ 135,286 The following tables present PCI loans by past due status as of June 30, 2019 and December 31, 2018: As of June 30, 2019 30-59 Days 60-89 Days 90 days or more Total Past Due Total PCI loans Current (In thousands) Residential mortgage loans $ - $ 7,750 $ 24,626 $ 32,376 $ 105,991 $ 138,367 Commercial mortgage loans - - 2,397 2,397 942 3,339 Total (1) $ - $ 7,750 $ 27,023 $ 34,773 $ 106,933 $ 141,706 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 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 and commercial mortgage loans past due 30-59 days as of June 30, 2019 amounted to $ 13.7 million and $ 0.1 million, respectively. PCI residential mortgage loans past due 30-59 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. 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. This difference is neither accreted into income nor recorded on the Corporation’s consolidated statements of financial condition. The excess of cash flows expected to be collected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loans, using the effective-yield method. Changes in Accretable Yield of Acquired Loans Subsequent to the acquisition of loans, the Corporation is required to periodically evaluate its estimate of cash flows expected to be collected. These evaluations, performed quarterly, require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Subsequent changes in the estimated cash flows expected to be collected may result in changes in the accretable yield and non-accretable difference or reclassifications from non-accretable yield to accretable yield. Increases in the cash flows expected to be collected will generally result in an increase in interest income over the remaining life of the loan or pool of loans. Decreases in expected cash flows due to further credit deterioration will generally result in an impairment charge recognized in the Corporation’s provision for loan and lease losses, resulting in an increase to the allowance for loan and lease losses. As of each June 30, 2019 and December 31, 2018, the reserve related to PCI loans amounted to $ 11.4 million. Changes in the accretable yield of PCI loans for the quarters and six-month periods ended June 30, 2019 and 2018 were as follows: Quarter Ended Six-Month Period Ended June 30, June 30, June 30, June 30, 2019 2018 2019 2018 (In thousands) Balance at beginning of period $ 91,060 $ 101,059 $ 93,493 $ 103,682 Accretion recognized in earnings ( 2,365) ( 2,570) ( 4,798) ( 5,193) Balance at end of period $ 88,695 $ 98,489 $ 88,695 $ 98,489 Changes in the carrying amount of PCI loans accounted for pursuant to ASC Topic 310-30 were as follows: Quarter Ended Six-Month Period Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 (In thousands) Balance at beginning of period $ 144,443 $ 155,281 $ 146,640 $ 158,174 Accretion 2,365 2,570 4,798 5,193 Collections ( 4,260) ( 4,359) ( 8,100) ( 7,755) Foreclosures ( 842) ( 1,250) ( 1,632) ( 3,370) Ending balance $ 141,706 $ 152,242 $ 141,706 $ 152,242 Allowance for loan losses ( 11,434) ( 11,354) ( 11,434) ( 11,354) Ending balance, net of allowance for loan losses $ 130,272 $ 140,888 $ 130,272 $ 140,888 Changes in the allowance for loan losses related to PCI loans were as follows: Quarter Ended Six-Month Period Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 (In thousands) Balance at beginning of period $ 11,354 $ 11,251 $ 11,354 $ 11,251 Provision for loan losses 80 103 80 103 Balance at the end of period $ 11,434 $ 11,354 $ 11,434 $ 11,354 The outstanding principal balance of PCI loans, including amounts charged off by the Corporation, amounted to $ 174.8 million as of June 30, 2019 (compared to - $ 181.1 million as of December 31, 2018). Purchases and Sales of Loans During the first six months of 2019, the Corporation purchased $ 9.3 million of residential mortgage loans as part of a strategic program to purchase ongoing residential mortgage loan production from mortgage bankers in Puerto Rico. In general, the loans purchased from mortgage bankers were conforming residential mortgage loans. Purchases of conforming residential mortgage loans provide the Corporation the flexibility to retain or sell the loans, including through securitization transactions, depending upon the Corporation’s interest rate risk management strategies. When the Corporation sells such loans, it generally keeps the servicing of the loans. In the ordinary course of business, the Corporation sells residential mortgage loans (originated or purchased) to GNMA and GSEs such as FNMA and FHLMC, which generally securitize the transferred loans into MBS for sale into the secondary market. During the first six months of 2019, the Corporation sold $ 115.0 million of FHA/VA mortgage loans to GNMA, which packaged them into MBS. Also, during the first six months of 2019, the Corporation sold approximately $ 59.9 million of performing residential mortgage loans to FNMA and FHLMC. The Corporation’s continuing involvement in these sold loans consists primarily of servicing the loans. In addition, the Corporation agreed to repurchase loans if it breaches any of the representations and warranties included in the sale agreement. These representations and warranties are consistent with the GSEs’ selling and servicing guidelines ( i.e. , ensuring that the mortgage was properly underwritten according to established guidelines). For loans sold to GNMA, the Corporation holds an option to repurchase individual delinquent loans issued on or after January 1, 2003 when the borrower fails to make any payment for three consecutive months. This option gives the Corporation the ability, but not the obligation, to repurchase the delinquent loans at par without prior authorization from GNMA. Under ASC Topic 860, “Transfer and Servicing,” once the Corporation has the unilateral ability to repurchase the delinquent loan, it is considered to have regained effective control over the loan and is required to recognize the loan and a corresponding repurchase liability on the balance sheet regardless of the Corporation’s intent to repurchase the loan. As of June 30, 2019 and December 31, 2018, rebooked GNMA delinquent loans included in the residential mortgage loan portfolio amounted to $ 41.9 million and $ 43.6 million, respectively. During the first six months of 2019 and 2018, the Corporation repurchased, pursuant to its repurchase option with GNMA, $ 10.7 million and $ 2.0 million, respectively, of loans previously sold to GNMA. The principal balance of these loans is fully guaranteed and the risk of loss related to the repurchased loans is generally limited to the difference between the delinquent interest payment advanced to GNMA, which is computed at the loan’s interest rate, and the interest payments reimbursed by FHA, which are computed at a pre-determined debenture rate. Repurchases of GNMA loans allow the Corporation, among other things, to maintain acceptable delinquency rates on outstanding GNMA pools and remain as a seller and servicer in good standing with GNMA. Historically, losses for violations of representations and warranties, and on optional repurchases of GNMA delinquent loans, have been immaterial and no provision has been made at the time of sale. Loan sales to FNMA and FHLMC are without recourse in relation to the future performance of the loans. The Corporation repurchased at par loans previously sold to FNMA and FHLMC in the amount of $ 64 thousand and $ 3 thousand during the first half of 2019 and 2018, respectively. The Corporation’s risk of loss with respect to these loans is also minimal as these repurchased loa

During 2019, the Corporation reduced to zero 0.4 million as of December 31, 2018). 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 condition and any changes to the reserve is included as part of other non-interest expenses in the consolidated statements of income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	NOTE 12 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES One of the market risks facing the Corporation is interest rate risk, which includes the risk that changes in interest rates will result in changes in the value of the Corporation’s assets or liabilities and will adversely affect the Corporation’s net interest income from its loan and investment portfolios. The overall objective of the Corporation’s interest rate risk management activities is to reduce the variability of earnings caused by changes in interest rates. The Corporation designates a derivative as a fair value hedge, cash flow hedge or economic undesignated hedge when it enters into the derivative contract. As of June 30, 2019 and December 31, 2018, all derivatives held by the Corporation were considered economic undesignated hedges. These undesignated 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 - Interest rate cap agreements provide the right to receive cash if a reference interest rate rises above a contractual rate. The value of the interest rate cap increases as the reference interest rate rises. The Corporation enters into interest rate cap agreements for protection from rising interest rates. Forward Contracts - Forward contracts are primarily sales of to-be-announced (“TBA”) MBS that will settle over the standard delivery date and do not qualify as “regular way” security trades. Regular-way security trades are contracts that have no net settlement provision and no market mechanism to facilitate net settlement and that provide for delivery of a security within the time frame generally established by regulations or conventions in the market place or exchange in which the transaction is being executed. The forward sales are considered derivative instruments that need to be marked to market. The Corporation uses these securities to economically hedge the FHA/VA residential mortgage loan securitizations of the mortgage-banking operations. The Corporation also reports as forward contracts the mandatory mortgage loan sales commitments that it enters into with GSEs that require or permit net settlement via a pair-off transaction or the payment of a pair-off fee. Unrealized gains (losses) are recognized as part of Mortgage banking activities in the consolidated 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. In these transactions, the Corporation generally participates as a buyer in one of the agreements and as a seller in the other agreement under the same terms and conditions. In addition, the Corporation enters into certain contracts with embedded derivatives that do not require separate accounting as these are clearly and closely related to the economic characteristics of the host contract. When the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract, it is bifurcated, carried at fair value, and designated as a trading or non-hedging derivative instrument.

As is the case with investment securities, the market value of derivative instruments is largely a function of the financial market’s expectations regarding the future direction of interest rates. Accordingly, current market values are not necessarily indicative of the future impact of derivative instruments on earnings. This will depend, for the most part, on the shape of the yield curve, and the level of interest rates, as well as the expectations for rates in the future. As of June 30, 2019, the Corporation had not entered into any derivative instrument containing credit-risk-related contingent features.

Offsetting [Abstract]
OFFSETTING OF ASSETS AND LIABILITIES	NOTE 13 – OFFSETTING OF ASSETS AND LIABILITIES The Corporation enters into master agreements with counterparties, primarily related to derivatives and repurchase agreements, that may allow for netting of exposures in the event of default. In an event of default, each party has a right of set-off against the other party for amounts owed under the related agreement and any other amount or obligation owed with respect to any other agreement or transaction between them. The following tables present information about the offsetting of financial assets and liabilities as well as derivative assets and liabilities: Offsetting of Financial Assets and Derivative Assets Gross Amounts Not Offset in the Statement of Financial Position Net Amounts of Assets Presented in the Statement of Financial Position Gross Amounts of Recognized Assets Gross Amounts Offset in the Statement of Financial Position Financial Instruments Cash Collateral As of June 30, 2019 Net Amount (In thousands) Description Derivatives $ 96 $ - $ 96 $ - $ ( 96) $ - Securities purchased under agreements to resell 200,000 ( 200,000) - - - - Total $ 200,096 $ ( 200,000) $ 96 $ - $ ( 96) $ - Gross Amounts Not Offset in the Statement of Financial Position Net Amounts of Assets Presented in the Statement of Financial Position Gross Amounts of Recognized Assets Gross Amounts Offset in the Statement of Financial Position Financial Instruments Cash Collateral As of December 31, 2018 Net Amount (In thousands) Description Derivatives $ 623 $ - $ 623 $ - $ ( 623) $ - Securities purchased under agreements to resell 200,000 ( 200,000) - - - - Total $ 200,623 $ ( 200,000) $ 623 $ - $ ( 623) $ - Offsetting of Financial Liabilities and Derivative Liabilities Gross Amounts Not Offset in the Statement of Financial Position Net Amounts of Liabilities Presented in the Statement of Financial Position Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Statement of Financial Position Financial Instruments Cash Collateral As of June 30, 2019 Net Amount (In thousands) Description Securities sold under agreements to repurchase $ 300,000 $ ( 200,000) $ 100,000 $ ( 100,000) $ - $ - Gross Amounts Not Offset in the Statement of Financial Position Net Amounts of Liabilities Presented in the Statement of Financial Position Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Statement of Financial Position Financial Instruments Cash Collateral As of December 31, 2018 Net Amount (In thousands) Description Securities sold under agreements to repurchase $ 350,086 $ ( 200,000) $ 150,086 $ ( 150,086) $ - $ -

Goodwill And Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	NOTE 14 – GOODWILL AND OTHER INTANGIBLES Goodwill as of June 30, 2019 and December 31, 2018 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 2018. The Corporation’s goodwill is related to the U.S. (Florida) reporting unit. There have been no significant events related to the Florida reporting unit that could indicate potential goodwill impairment since the date of the last evaluation; therefore, no goodwill impairment evaluation was performed during the first six months of 2019. Goodwill and other indefinite life intangibles are reviewed at least annually for impairment. In connection with the acquisition of the FirstBank-branded credit card loan portfolio, in the second quarter of 2012, the Corporation recognized a purchased credit card relationship intangible of $ 24.5 million ($ 4.7 million as of June 30, 2019 and $ 5.7 million as of December 31, 2018), which is being amortized over the remaining estimated life of 2.4 years on an accelerated basis based on the estimated attrition rate of the purchased credit card accounts, which reflects the Corporation’s estimate that it will realize the economic benefits of the intangible asset as the revenue stream generated by the cardholder relationship is realized. The core deposit intangible of $ 3.9 million (December 31, 2018 - $ 4.3 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 accounts and related customer records and recognized an insurance customer relationship intangible of $ 1.1 million ($ 0.5 million as of June 30, 2019 and $ 0.6 million as of December 31, 2018). 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 As of June 30, December 31, 2019 2018 (Dollars in thousands) Core deposit intangible: Gross amount $ 51,664 $ 51,664 Accumulated amortization (1) ( 47,761) ( 47,329) Net carrying amount $ 3,903 $ 4,335 Remaining amortization period (in years) 5.6 6.0 Purchased credit card relationship intangible: Gross amount $ 24,465 $ 24,465 Accumulated amortization (2) ( 19,806) ( 18,763) Net carrying amount $ 4,659 $ 5,702 Remaining amortization period (in years) 2.4 2.9 Insurance customer relationship intangible: Gross amount $ 1,067 $ 1,067 Accumulated amortization (3) ( 521) ( 445) Net carrying amount $ 546 $ 622 Remaining amortization period (in years) 3.5 4.0 For the quarter and six-month period ended June 30, 2019, the amortization expense of core deposit intangibles amounted to $ 0.2 million and $ 0.4 million, respectively (2018 - $ 0.2 million and $ 0.6 million, respectively). For the quarter and six-month period ended June 30, 2019, the amortization expense of the purchased credit card relationship intangible amounted to $ 0.5 million and $ 1.0 million, respectively (2018 - $ 0.6 million and $ 1.1 million, respectively). For the quarter and six-month periods ended June 30, 2019 and 2018, the amortization expense of the insurance customer relationship intangible amounted to $ thousand and $ thousand, respectively. The estimated aggregate annual amortization expense related to the intangible assets for future periods is as follows: Amount (In thousands) 2019 $ 1,537 2020 2,851 2021 2,658 2022 915 2023 622 2024 and after 525

NON-CONSOLIDATED VARIABLE INTER

NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	6 Months Ended

Transfers and Servicing [Abstract]
NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	NOTE 15 – NON CONSOLIDATED VARIABLE INTEREST ENTITIES (“VIE”) AND SERVICING ASSETS The Corporation transfers residential mortgage loans in sale or securitization transactions in which it has continuing involvement, including servicing responsibilities and guarantee arrangements. All such transfers have been accounted for as sales as required by applicable accounting guidance. When evaluating the need to consolidate counterparties to which the Corporation has transferred assets, or with which the Corporation has entered into other transactions, the Corporation first determines if the counterparty is an entity for which a variable interest exists. If no scope exception is applicable and a variable interest exists, the Corporation then evaluates 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 typically transfers first lien residential mortgage loans in conjunction with GNMA securitization transactions in which the loans are exchanged for cash or securities that are readily redeemed for cash proceeds and servicing rights. The securities issued through these transactions are guaranteed by 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 June 30, 2019, the Corporation serviced loans securitized through GNMA with a principal balance of $ 1.8 billion. Trust-Preferred Securities In 2004, FBP Statutory Trust I, a financing trust that is wholly owned by the Corporation, sold to institutional investors $ 100 million of its variable-rate trust-preferred securities (“TRuPs”). FBP Statutory Trust I used the proceeds of the issuance, together with the proceeds of the purchase by the Corporation of $ 3.1 million of FBP Statutory Trust I variable-rate common securities, to purchase $ 103.1 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. Also in 2004, FBP Statutory Trust II, a financing trust that is wholly owned by the Corporation, sold to institutional investors $ 125 million of its variable-rate TRuPs. FBP Statutory Trust II used the proceeds of the issuance, together with the proceeds of the purchase by the Corporation of $ 3.9 million of FBP Statutory Trust II variable-rate common securities, to purchase $ 128.9 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. The debentures are presented in the Corporation’s consolidated statement of financial condition as Other Borrowings, net of related issuance costs. The variable-rate TRuPs are fully and unconditionally guaranteed by the Corporation. The Junior Subordinated Deferrable Debentures issued by the Corporation in April 2004 and September 2004 mature on June 17, 2034 and September 20, 2034, respectively; however, under certain circumstances, the maturity of Junior Subordinated Deferrable Debentures may be shortened (such shortening would result in a mandatory redemption of the variable-rate TRuPs). During the first quarter of 2018, the Corporation completed the repurchase of $ 23.8 million of TRuPs of the FBP Statutory Trust I that were auctioned in a public sale at which the Corporation was invited to participate. The Corporation repurchased and cancelled the repurchased TRuPs, which resulted in a commensurate reduction in the related Floating Rate Junior Subordinated Debentures. The Corporation’s winning bid equated to 90% of the $ 23.8 million par value. The 10% discount resulted in a gain of approximately $ 2.3 million, which is reflected in the statement of income as “Gain on early extinguishment of debt.” The Collins Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act eliminated certain TRuPs from Tier 1 Capital; however, these instruments may remain in Tier 2 capital until the instruments are redeemed or mature. Under the indentures, the Corporation has the right, from time to time, and without causing an event of default, to defer payments of interest on the Junior Subordinated Deferrable Debentures by extending the interest payment period at any time and from time to time during the term of the subordinated debentures for up to twenty consecutive quarterly periods. During the second quarter of 2016, the Corporation, having received approval from the Federal Reserve, paid $ 31.2 million for all of the accrued but deferred interest payments plus the interest for the second quarter of 2016 on the Corporation’s subordinated debentures associated with its TRuPs. Subsequently, the Corporation has received quarterly approvals that have enabled it to make scheduled quarterly interest payments. As of June 30, 2019, the Corporation was current on all interest payments due on its subordinated debt. In 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 Federal Reserve Bank. 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 TRuPs, incurring or guaranteeing debt or purchasing or redeeming any corporate stock. The Corporation has received approval to make the subordinated debentures’ quarterly payment through December 2019, subject to conditions 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 the 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 interest to the Bank. Interest income is shared to a certain extent with the FDIC, which has an interest only strip (“IO”) tied to the cash flows of the underlying loans and is entitled to receive the excess of the interest income less a servicing fee over the variable rate income that the Bank earns on the securities. This IO is limited to the weighted-average coupon on the securities. The FDIC became the owner of the IO upon its intervention of the seller, a failed financial institution. No recourse agreement exists, and the Bank, as a sole holder of the certificates, absorbs all risks from losses on non-accruing loans and repossessed collateral. As of June 30, 2019, the amortized cost and fair value of the Grantor Trusts amounted to $ 17.9 million and $ 12.5 million, respectively, with a weighted average yield of 4.39%, 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 and majority owned by PRLP Ventures LLC (“PRLP”), a company created by Goldman, Sachs & Co. and Caribbean Property Group. In connection with the sale, the Corporation received $ 88.5 million in cash and a 35% interest in CPG/GS, and made a loan in the amount of $ 136.1 million representing seller financing provided by FirstBank. The loan matured in February 2018 and was refinanced and consolidated with other outstanding loans of CPG/GS in the second quarter of 2018. As of June 30, 2019, the carrying amount of the refinanced loan was $ 0.4 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 estate 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. CPG/GS has used cash proceeds on the loan 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 FirstBank’s interest in CPG/GS being subordinate to PRLP’s interest. CPG/GS will then begin to make payments pro rata to PRLP and FirstBank, 35% and 65%, respectively, until FirstBank has achieved a 12% return on its invested capital and the aggregate amount of distributions is equal to FirstBank’s capital contributions to CPG/GS. The Bank has determined that CPG/GS is a VIE in which the Bank is not the primary beneficiary. In determining the primary beneficiary of CPG/GS, the Bank considered applicable guidance that requires the Bank to qualitatively assess the determination of the primary beneficiary (or consolidator) of CPG/GS based on whether it has both the power to direct the activities of CPG/GS that most significantly affect the entity’s economic performance and the obligation to absorb losses of, or the right to receive benefits from, CPG/GS that could potentially be significant to the VIE. The Bank determined that it does not have the power to direct the activities that most significantly impact the economic performance of CPG/GS as it does not have the right to manage or influence the loan portfolio, foreclosure proceedings, or the construction and sale of the property; therefore, the Bank concluded that it is not the primary beneficiary of CPG/GS. Servicing Assets The Corporation sells residential mortgage loans to GNMA, which generally securitizes the transferred loans into MBS. Also, certain conventional conforming loans are sold to FNMA or FHLMC with servicing retained. The Corporation recognizes as separate assets the rights to service loans for others, whether those servicing assets are originated or purchased. Servicing assets are included as part of Other assets in the consolidated statement of financial condition. The changes in servicing assets are shown below: Quarter Ended Six-Month Period Ended June 30, June 30, (In thousands) 2019 2018 2019 2018 Balance at beginning of period $ 27,431 $ 26,135 $ 27,428 $ 25,255 Capitalization of servicing assets 1,001 1,138 1,869 2,025 Amortization ( 1,166) ( 729) ( 1,976) ( 1,466) Temporary impairment recoveries (charges), net - 617 ( 20) 1,330 Other (1) ( 35) 30 ( 70) 47 Balance at end of period $ 27,231 $ 27,191 $ 27,231 $ 27,191 (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: Quarter Ended Six-Month Period Ended June 30, June 30, 2019 2018 2019 2018 (In thousands) Balance at beginning of period $ 50 $ 673 $ 30 $ 1,451 Temporary impairment charges - 20 24 37 OTTI of servicing assets - - - ( 65) Recoveries - ( 637) ( 4) ( 1,367) Balance at end of period $ 50 $ 56 $ 50 $ 56 The components of net servicing income are shown below: Quarter Ended Six-Month Period Ended June 30, June 30, 2019 2018 2019 2018 (In thousands) Servicing fees $ 2,107 $ 2,058 $ 4,167 $ 4,178 Late charges and prepayment penalties 157 146 311 266 Adjustment for loans repurchased ( 35) 30 ( 70) 47 Other - - ( 15) - Servicing income, gross 2,229 2,234 4,393 4,491 Amortization and impairment of servicing assets ( 1,166) ( 112) ( 1,996) ( 136) Servicing income, net $ 1,063 $ 2,122 $ 2,397 $ 4,355 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 Six-Month Period Ended June 30, 2019: Constant prepayment rate: Government-guaranteed mortgage loans 6.3 % 6.2 % Conventional conforming mortgage loans 6.8 % 6.7 % Conventional non-conforming mortgage loans 9.3 % 9.0 % 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 % Six-Month Period Ended June 30, 2018: Constant prepayment rate: Government-guaranteed mortgage loans 5.7 % 5.6 % Conventional conforming mortgage loans 6.3 % 6.2 % Conventional non-conforming mortgage loans 9.6 % 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 % 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 June 30, 2019 were as follows: (Dollars in thousands) Carrying amount of servicing assets $ 27,231 Fair value $ 30,396 Weighted-average expected life (in years) 8.32 Constant prepayment rate (weighted-average annual rate) 6.48 % Decrease in fair value due to 10% adverse change $ 750 Decrease in fair value due to 20% adverse change $ 1,468 Discount rate (weighted-average annual rate) 11.26 % Decrease in fair value due to 10% adverse change $ 1,427 Decrease in fair value due to 20% adverse change $ 2,739 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 .

As of June 30, 2019 and December 31, 2018, there were 222,055,625 and 221,789,509 shares issued, respectively, and 217,328,179 and 217,235,140 shares outstanding, respectively. Refer to Note 4 – Stock Based Compensation, for information about transactions related to common stock under the Omnibus Plan. On May 16, 2019, the Corporation’s Board of Directors, after receiving regulatory approval, declared a quarterly cash dividend of $ 0.03 per common share that was paid on June 14, 2019 to shareholders of record on May 30, 2019. For the quarter and six-month period ended June 30, 2019, total cash dividends declared on shares of common stock amounted to $ 6.5 million and $ 13.1 million, respectively. The Corporation has received regulatory approval to pay quarterly dividends on common stock through December 2019, subject to conditions established in the agreement with regulators. The Corporation intends to request approval in future periods to continue quarterly dividend payments on common stock. Preferred Stock The Corporation has 50,000,000 authorized shares of preferred stock with a par value of $ 1.00, redeemable at the Corporation’s option, subject to certain terms. This stock may be issued in series and the shares of each series have such rights and preferences as are fixed by the Board of Directors when authorizing the issuance of that particular series. As of June 30, 2019, the Corporation has five outstanding series of non-convertible, non-cumulative preferred stock: 7.125% non-cumulative perpetual monthly income preferred stock, Series A; 8.35% non-cumulative perpetual monthly income preferred stock, Series B; 7.40% non-cumulative perpetual monthly income preferred stock, Series C; 7.25% non-cumulative perpetual monthly income preferred stock, Series D; and 7.00% non-cumulative perpetual monthly income preferred stock, Series E. The liquidation value per share is $ 25. Effective January 17, 2012, the Corporation delisted all of its outstanding series of non-convertible, non-cumulative preferred stock from the New York Stock Exchange. The Corporation has not arranged for listing and/or registration on another national securities exchange or for quotation of the Series A through E Preferred Stock in a quotation medium. In December 2016, for the first time since July 2009, the Corporation 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 request 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 TRuPs, incurring or guaranteeing debt or purchasing or redeeming any corporate stock. Treasury stock During the first six months of 2019 and 2018, the Corporation withheld an aggregate of 170,827 shares and 424,810 shares, respectively, of the restricted stock that vested during the first six months of 2019 and 2018, and common stock paid to certain senior officers as additional compensation in 2018, to cover employees’ payroll and income tax withholding liabilities; these shares are held as treasury stock. As of June 30, 2019 and December 31, 2018, the Corporation had 4,727,446 and 4,554,369 shares held as treasury stock, respectively. FirstBank Statutory Reserve (Legal Surplus) The Banking Law of the Commonwealth of Puerto Rico requires that a minimum of 10% of FirstBank’s net income for the year be transferred to a legal surplus reserve until such surplus equals the total of paid-in-capital on common and preferred stock. Amounts transferred to the legal surplus reserve from Retained earnings are not available for distribution to the Corporation, including for payment as dividends to the stockholders, without the prior consent of the Puerto Rico Commissioner of Financial Institutions. The Puerto Rico Banking Law provides that, when the expenditures of a Puerto Rico commercial bank are greater than receipts, the excess of the expenditures over receipts must be charged against the undistributed profits of the bank, and the balance, if any, must be charged against the legal surplus reserve, as a reduction thereof. If there is no legal surplus reserve sufficient to cover such balance in whole or in part, the outstanding amount must be charged against the capital account and the Bank cannot pay dividends until it can replenish the legal surplus reserve to an amount of at least 20% of the original capital contributed. During the fourth quarter of 2018, $ 20.5 million was transferred to the legal surplus reserve. FirstBank’s legal surplus reserve, included as part of Retained earnings in the Corporation’s consolidated statements of financial condition, amounted to $ 80.2 million as of June 30, 2019. There were no

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 21 - INCOME TAXES Income tax expense includes Puerto Rico and USVI income taxes, as well as applicable U.S. federal and state taxes. The Corporation is subject to Puerto Rico income tax on its income from all sources. As a Puerto Rico corporation, First BanCorp. is treated as a foreign corporation for U.S. and USVI income tax purposes and, accordingly, is generally subject to U.S. and USVI income tax only on its income from sources within the U.S. and USVI or income effectively connected with the conduct of a trade or business in those jurisdictions. Any such tax paid in the U.S. and USVI is also creditable against the Corporation’s Puerto Rico tax liability, subject to certain conditions and limitations. Under the Puerto Rico Internal Revenue Code of 2011, as amended (the “2011 PR Code”), the Corporation and its subsidiaries are treated as separate taxable entities and are generally not entitled to file consolidated tax returns and, thus, the Corporation is generally not entitled to utilize losses from one subsidiary to offset gains in another subsidiary. Accordingly, in order to obtain a tax benefit from a net operating loss (“NOL”), a particular subsidiary must be able to demonstrate sufficient taxable income within the applicable NOL carry-forward period. Pursuant to the 2011 PR Code, the carry-forward period for NOLs incurred during taxable years that commenced after December 31, 2004 and ended before January 1, 2013 is 12 years; for NOLs incurred during taxable years commencing after December 31, 2012, the carryover period is 10 years. The 2011 PR Code provides a dividend received deduction of 100% on dividends received from “controlled” subsidiaries subject to taxation in Puerto Rico and 85% on dividends received from other taxable domestic corporations. On December 10, 2018, the Governor of Puerto Rico signed into law Act 257 (“Act 257”) to amend some of the provisions of the 2011 PR Code, as amended. Act 257 introduced various changes to the income tax regime in the case of individuals and corporations, and the sales and use taxes, which took effect on January 1, 2019, including, among others, (i) a reduction in the Puerto Rico maximum 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 NOL deduction against a partnership distributable share, adversely impacting a tax action taken in 2017 for FirstBank Insurance under which the Corporation was previously allowed to offset pass-through income earned by FirstBank Insurance with net operating losses at the holding company level; and (iv) other limitations on certain deductions, such as meals and entertainment deductions. 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 Puerto Rico income taxes and by doing business through an International Banking Entity (“IBE”) unit of the Bank, and through the Bank’s subsidiary, FirstBank Overseas Corporation, whose interest income and gain on sales is exempt from Puerto Rico income taxation. The IBE and FirstBank Overseas Corporation were created under the International Banking Entity Act of Puerto Rico, which provides for total Puerto Rico tax exemption on net income derived by IBEs operating in Puerto Rico on the specific activities identified in the IBE Act. An IBE that operates as a unit of a bank pays income taxes at the corporate standard rates to the extent that the IBE’s net income exceeds 20% of the bank’s total net taxable income. For the second quarter and first six months of 2019, the Corporation recorded an income tax expense of $ 18.0 million and $ 35.6 million, respectively, compared to $ 10.2 million and $ 17.9 million, respectively, for the comparable periods in 2018. The variance in the income tax expense for the second quarter and first six months of 2019, when compared to the same periods in 2018, was primarily related to a higher proportion of taxable to exempt income. For the six-month period ended June 30, 2019, the Corporation calculated the provision for income taxes by applying the estimated annual effective tax rate for the full fiscal year to ordinary income or loss. In the computation of the consolidated worldwide annual estimated effective tax rate, ASC Topic 740-270, “Income Taxes” (“ASC Topic 740-270”), requires the exclusion of legal entities with pre-tax losses from which a tax benefit cannot be recognized. The Corporation’s estimated annual effective tax rate in the first six months of 2019, excluding entities from which a tax benefit cannot be recognized and discrete items, was 29% compared to 25% for the first six months of 2018. The estimated annual effective tax rate, including all entities, for 2019 was 29% ( 30% excluding discrete items), compared to 24% for the first six months of 2018 ( 25% excluding discrete items). The Corporation’s deferred tax asset amounted to $ 290.3 million as of June 30, 2019, net of a valuation allowance of $ 92.8 million, and management concluded, based upon the assessment of all positive and negative evidence, that it is more likely than not that the Corporation will generate sufficient taxable income within the applicable NOL carry-forward periods to realize such amount. The deferred tax asset of the Corporation’s banking subsidiary, FirstBank, amounted to $ 290.2 million as of June 30, 2019, net of a valuation allowance of $ 60.0 million, compared to a deferred tax asset of $ 319.8 million, net of a valuation allowance of $ 68.1 million, as of December 31, 2018. The Corporation has U.S. and USVI 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. In 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 had occurred during such period. The Section 382 limitation has resulted in higher U.S. and USVI income tax liabilities than we would have incurred in the absence of such limitation. The Corporation has mitigated to an extent the adverse effects associated with the Section 382 limitation as any such tax paid in the U.S. or USVI can be creditable against Puerto Rico tax liabilities or taken as a deduction against taxable income. However, our ability to reduce our Puerto Rico tax liability through such a credit or deduction depends on our tax profile at each annual taxable period, which is dependent on various factors. For the second quarter and six-month period ended June 30, 2019, the Corporation incurred an income tax expense of approximately $ 1.2 million and $ 2.2 million, respectively, related to its U.S. operations, compared to $ 1.0 million and $ 2.6 million, respectively, for the comparable periods in 2018. The limitation did not impact the USVI operations for the second quarter and six-month periods ended June 30, 2019 and 2018. As of June 30, 2019, the Corporation did not have Unrecognized Tax Benefits recorded on its books. The Corporation classifies all interest and penalties, if any, related to tax uncertainties as income tax expense. Audit periods remain open for review until the statute of limitations has passed. The statute of limitations under the 2011 PR Code is four years; the statute of limitations for U.S. and USVI income tax purposes is three years after a tax return is due or filed, whichever is later. The completion of an audit by the taxing authorities or the expiration of the statute of limitations for a given audit period could result in an adjustment to the Corporation’s liability for income taxes. Any such adjustment could be material to the results of operations for any given quarterly or annual period based, in part, upon the results of operations for the given period. For U.S. and USVI income tax purposes, all tax years subsequent to 2014 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2014 remain open to examination.

FAIR VALUE

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 23 – FAIR VALUE Fair Value Measurement The FASB authoritative guidance for fair value measurement defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This guidance also establishes a fair value hierarchy for classifying financial instruments. The hierarchy is based on whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. Three levels of inputs may be used to measure fair value: Level 1 Valuations of Level 1 assets and liabilities are obtained from readily-available pricing sources for market transactions involving identical assets or liabilities. Level 1 assets and liabilities include equity securities that trade in an active exchange market, as well as certain U.S. Treasury and other U.S. government and agency securities and corporate debt securities that are traded by dealers or brokers in active markets. Level 2 Valuations of Level 2 assets and liabilities are based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include (i) MBS for which the fair value is estimated based on the value of identical or comparable assets, (ii) debt securities with quoted prices that are traded less frequently than exchange-traded instruments, and (iii) derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Level 3 Valuations of Level 3 assets and liabilities are based on unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined by using pricing models for which the determination of fair value requires significant management judgments estimation. Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities available for sale and marketable equity securities held at fair value The fair value of investment securities was the market value based on quoted market prices (as is the case with 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, issuer spreads, bids, offers and reference data, including market research operations (Level 2). Observable prices in the market already consider the risk of nonperformance. If listed prices or quotes are not available, fair value is based upon discounted cash flow models that use unobservable inputs due to the limited market activity of the instrument, as is the case with certain private label MBS held by the Corporation (Level 3). Derivative instruments The fair value of most of the Corporation’s derivative instruments is based on observable market parameters and takes into consideration the credit risk component of paying counterparties, when appropriate. On interest caps, only the seller’s credit risk is considered. The 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 instruments for the quarters and six-month periods ended June 30, 2019 and 2018 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 value 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, which are guaranteed by the PRHFA. A significant increase (decrease) in the assumed rate would lead to a higher (lower) fair value estimate. The fair value of these bonds was based on a discounted cash flow analysis that contemplates the credit quality of the holder of second mortgages and a discount for liquidity constraints on the bonds considering the absence of an active market for them. Due to the guarantee of the PRHFA and other applicable contractual safeguards, no additional credit spread is applied for debt service default. There were no Additionally, fair value is used on a nonrecurring basis to evaluate certain assets in accordance with GAAP. Adjustments to fair value usually result from the application of lower-of-cost or market accounting ( e.g. , loans held for sale carried at the lower-of-cost or fair value and repossessed assets) or write downs of individual assets ( e.g. , goodwill and loans). As of June 30, 2019, impairment or valuation adjustments were recorded for assets recognized at fair value on a non-recurring basis as shown in the following table: Losses recorded for the Quarter Ended Losses recorded for the Six-Month Period Ended Carrying value as of June 30, 2019 June 30, 2019 June 30, 2019 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 346,627 $ ( 1,934) $ ( 10,569) OREO (2) - - 118,081 ( 2,820) ( 4,829) Loans held for sale (3) - - 7,144 - - (1) Consists mainly of impaired commercial and construction loans.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMER	NOTE 24 – REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition In accordance with ASC Topic 606, “Revenues from Contracts with Customers,” revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration to which the Corporation expects to be entitled in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC Topic 606, the Corporation performs the following five steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when (or as) the Corporation satisfies a performance obligation. The Corporation only applies the five-step model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC Topic 606, the Corporation assesses the goods or services that are promised within each contract, identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Corporation then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Disaggregation of Revenue The following table summarizes the Corporation’s revenue, which includes net interest income on financial instruments and non-interest income, disaggregated by type of service and business segment for the quarters and six-month periods ended June 30, 2019 and 2018: (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total Quarter ended June 30, 2019: Net interest income (1) $ 17,311 $ 62,216 $ 22,539 $ 17,862 $ 16,142 $ 6,476 $ 142,546 Service charges and fees on deposit accounts - 3,409 1,588 - 150 740 5,887 Insurance commissions - 1,879 - - 18 128 2,025 Merchant-related income - 1,102 - - - 215 1,317 Credit and debit card fees - 4,745 324 - 180 520 5,769 Other service charges and fees 30 980 316 - 224 717 2,267 Not in scope of Topic 606 (1) 4,219 411 69 72 197 ( 10) 4,958 Total non-interest income 4,249 12,526 2,297 72 769 2,310 22,223 Total Revenue $ 21,560 $ 74,742 $ 24,836 $ 17,934 $ 16,911 $ 8,786 $ 164,769 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total Quarter ended June 30, 2018: Net interest income (1) $ 20,102 $ 55,138 $ 20,443 $ 12,443 $ 15,053 $ 7,292 $ 130,471 Service charges and fees on deposit accounts - 3,279 1,230 - 142 693 5,344 Insurance commissions - 1,618 - - 33 129 1,780 Merchant-related income - 964 201 - - 208 1,373 Credit and debit card fees - 4,296 336 - 151 518 5,301 Other service charges and fees 21 811 304 71 ( 60) 269 1,416 Not in scope of Topic 606 (1) 4,645 283 140 - 194 ( 4) 5,258 Total non-interest income 4,666 11,251 2,211 71 460 1,813 20,472 Total Revenue $ 24,768 $ 66,389 $ 22,654 $ 12,514 $ 15,513 $ 9,105 $ 150,943 For the six-month periods ended June 30, 2019 and 2018, substantially all of the Corporation’s revenue within the scope of ASC Topic 606 was related to performance obligations satisfied at a point in time. The following is a discussion of revenues under the scope of ASC Topic 606. Service Charges and Fees on Deposit Accounts Service charges and fees on deposit accounts relate to fees generated from a variety of deposit products and services rendered to customers. Charges include, but are not limited to, overdraft fees, non-sufficient fund fees, dormant fees and monthly service charges. Such fees are recognized concurrently with the event on a daily basis or on a monthly basis depending upon the customer’s cycle date. These depository arrangements are considered day-to-day contracts that do not extend beyond the services performed, as customers have the right to terminate these contracts with no penalty or, if any, nonsubstantive penalties. Insurance Commissions For insurance commissions, which include regular and contingent commissions paid to the Corporation’s insurance agency, the agreements contain a performance obligation related to the sale/issuance of the policy and ancillary administrative post-issuance support. The performance obligation will be satisfied as the policies are issued and revenue will be recognized at that point in time. In addition, contingent commission income was found to be constrained, as defined under the new standard. Contingent commission income will be included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or payments are received. For the quarter and six-month period ended June 30, 2019, the Corporation recognized revenue of $ 4 thousand and $ 2.7 million, respectively, as payments were confirmed and constraints were released, compared to $ 0.3 million and $ 2.4 million for the same periods in 2018. Merchant-related Income For merchant-related income, the determination of which included the consideration of a 2015 sale of merchant contracts that involved sales of point of sale (“POS”) terminals and entry into a marketing alliance under a revenue-sharing agreement, the Corporation concluded that control of the POS terminals and merchant contracts was transferred to the customer at the contract’s inception. With respect to the related revenue-sharing agreement, the Corporation satisfies the marketing alliance performance obligation over the life of the contract, and the associated transaction price is recognized as the entity performs and any constraints over the variable consideration are resolved. Credit and Debit Card Fees Credit and debit card fees primarily represent revenues earned from interchange fees and ATM fees. Interchange and network revenues are earned on credit and debit card transactions conducted with payment networks. ATM fees are primarily earned as a result of surcharges assessed to non-FirstBank customers who use a FirstBank ATM. Such fees are generally recognized concurrently with the delivery of services on a daily basis. Other Fees Other fees primarily include revenues generated from wire transfers, lockboxes, and bank issuances of checks. 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. During 2015, the Bank entered into a long-term strategic marketing alliance with another entity to which the Bank sold its merchant contracts portfolio and related POS terminals. Merchant services are marketed through FirstBank’s branches and offices in Puerto Rico and the Virgin Islands. Under the marketing and referral agreement, FirstBank shares with this entity revenues generated by the merchant contracts over the term of the 10-year agreement. As of June 30, 2019, and December 31, 2018, this contract liability amounted to $ 1.9 million and $ 2.1 million, respectively, which will be recognized over the remaining term of the contract. For the quarters and six-month period ended June 30, 2019 and 2018, the Corporation recognized revenue and its contract liabilities decreased by approximately $ 0.1 million and $ 0.2 million, respectively, due to the completion of performance over time. There were no changes in contract liabilities due to changes in transaction price estimates . A contract asset is the right to consideration for transferred goods or services when the amount is conditioned on something other than the passage of time. As of June 30, 2019 and December 31, 2018, there were no receivables from contracts with customers or contract assets recorded on the Corporation’s consolidated financial statements. Other Except for the contract liabilities noted above, the Corporation did not have any significant performance obligations as of June 30, 2019. The Corporation also did not have any material contract acquisition costs and did not make any significant judgments or estimates in recognizing revenue for financial reporting purposes.

Segment Reporting [Abstract]
SEGMENT INFORMATION	NOTE 26 – SEGMENT INFORMATION Based upon the Corporation’s organizational structure and the information provided to the Chief Executive Officer and, to a lesser extent, the Board of Directors of the Corporation, 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 June 30, 2019, the Corporation had six The Commercial and Corporate Banking segment consists of the Corporation’s lending and other services for large customers represented by specialized and middle-market clients and the public sector. The Commercial and Corporate Banking segment offers commercial loans, including commercial real estate and construction loans, and floor plan financings, as well as other products, such as cash management and business management services. The Mortgage Banking segment consists of the origination, sale, and servicing of a variety of residential mortgage loans. The Mortgage Banking segment also acquires and sells mortgages in the secondary markets. In addition, the Mortgage Banking segment includes mortgage loans purchased from other local banks and mortgage bankers. The Consumer (Retail) Banking segment consists of the Corporation’s consumer lending and deposit-taking activities conducted mainly through its branch network and loan centers. The Treasury and Investments segment is responsible for the Corporation’s investment portfolio and treasury functions that are executed to manage and enhance liquidity. This segment lends funds to the Commercial and Corporate Banking, Mortgage Banking 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 Operations segment consists of all banking activities conducted by the Corporation in the USVI and BVI, including commercial and retail banking services. The accounting policies of the segments are the same as those referred to in Note 1, “Nature of Business and Summary of Significant Accounting Policies,” in the audited consolidated financial statements of the Corporation for the year ended December 31, 2018, which are included in the 2018 Annual Report on Form 10-K. 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-interest expenses. The segments are also evaluated based on the average volume of their interest-earning assets less the allowance for loan and lease losses.

Commitments And Contingencies Disclosure [Abstract]
REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES	NOTE 27 – REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES The Corporation and FirstBank are each subject to various regulatory capital requirements imposed by the federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on the Corporation’s financial statements and activities. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation must meet specific capital guidelines that involve quantitative measures of the Corporation’s and FirstBank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Corporation’s capital amounts and classification are also subject to qualitative judgments and adjustment by the regulators with respect to minimum capital requirements, components, risk weightings, and other factors. On October 3, 2017, the New York FED terminated the Written Agreement entered into on June 3, 2010 by the Corporation and 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 TRuPs, 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 elements of the Basel III have been deferred by the federal banking agencies. The Corporation and FirstBank compute risk-weighted assets using the Standardized Approach required by the Basel III rules. The Basel III rules require the Corporation to maintain an additional capital conservation buffer of 2.5% to avoid limitations on both (i) capital distributions ( e.g. , repurchases of capital instruments, dividends and interest payments on capital instruments,) and (ii) discretionary bonus payments to executive officers and heads of major business lines. 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 was progressively increased over a four-year period, increasing by that same percentage amount on each subsequent January 1 until it reached the fully phased-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 capital to risk-weighted assets ratio of at least 4.5%, plus the 2.5% “capital conservation buffer,” resulting in a required minimum CET1 ratio of at least 7%; (ii) a minimum ratio of total Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum Tier 1 capital ratio of 8.5%; (iii) a minimum ratio of total Tier 1 plus Tier 2 capital to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum total capital ratio of 10.5%; and (iv) a required minimum leverage ratio of 4%, calculated as the ratio of Tier 1 capital to average on-balance sheet (non-risk adjusted) assets. In addition, as required under the Basel III rules, the Corporation’s TRuPs were fully phased-out from Tier 1 capital as of January 1, 2016. However, the Corporation’s TRuPs may continue to be included in Tier 2 capital until the instruments are redeemed or mature. The Federal Reserve Board, the FDIC, and the Office of the Comptroller of the Currency (collectively “the agencies”) have issued several rulemakings over the last two years to simplify certain aspects of the capital rule. For example, the capital rule included transitional arrangements for certain requirements. Under such transitional arrangements in the capital rule, any amount of mortgage servicing assets, temporary difference deferred tax assets, and investments in the capital of unconsolidated financial institutions that a banking organization did not deduct from common equity tier 1 capital was risk weighted at 100 percent until January 1, 2018. In 2017, the agencies adopted a rule (transition rule) to allow non-advanced approaches banking organizations, such as the Corporation and FirstBank, to continue to apply the transition treatment in effect in 2017 (including the 100 percent risk weight for mortgage servicing assets, temporary difference deferred tax assets, and significant investments in the capital of unconsolidated financial institutions) while the agencies considered the simplifications proposal. On July 9, 2019, the agencies adopted a final rule that supersedes the regulatory capital transition rules and eliminates the transition provisions that are no longer operative. The final rule will be generally effective April 1, 2020 and eliminates: (i) the 10 percent common equity tier 1 capital deduction threshold, which applies individually to holdings of mortgage servicing assets, temporary difference deferred tax assets, and significant investments in the capital of unconsolidated financial institutions in the form of common stock; (ii) the 15 percent common equity tier 1 capital deduction threshold, which applies to the aggregate amount of such items; (iii) the 10 percent threshold for non-significant investments, which applies to holdings of regulatory capital of unconsolidated financial institutions; and (iv) the deduction treatment for significant investments in the capital of unconsolidated financial institutions that are not in the form of common stock. Instead of the current capital rule's treatments for mortgage servicing assets, temporary difference deferred tax assets, and investments in the capital of unconsolidated financial institutions, the final rule requires non-advanced approaches banking organizations to deduct from common equity tier 1 capital any amount of mortgage servicing assets, temporary difference deferred tax assets, and investments in the capital of unconsolidated financial institutions that individually exceed 25 percent of common equity tier 1 capital of the banking organization (the 25 percent common equity tier 1 capital deduction threshold). The final rule retains the deferred requirement that requires a banking organization to apply a 250 percent risk weight to non-deducted mortgage servicing assets or temporary difference deferred tax assets.

These financial instruments may include commitments to extend credit. As of June 30, 2019, commitments to extend credit amounted to approximately $ 1.3 billion, of which $ 658.2 million relates to credit card loans. Commercial and financial standby letters of credit amounted to approximately $ 52.2 million. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses. Since certain commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. For most of the commercial lines of credit, the Corporation has the option to reevaluate the agreement prior to additional disbursements. In the case of credit cards and personal lines of credit, the Corporation can cancel the unused credit facility at any time and without cause. As of June 30, 2019, First BanCorp. and its subsidiaries were defendants in various legal proceedings arising in the ordinary course of business. On at least a quarterly basis, the Corporation assesses its liabilities and contingencies in connection with threatened and outstanding legal cases, matters and proceedings, utilizing the latest information available. For cases, matters and proceedings 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. For 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 of them are currently in preliminary stages), the existence in some of the current proceedings of multiple defendants whose share of liability has yet to be determined, the numerous unresolved issues in the proceedings, and the inherent uncertainty of the various potential outcomes of such proceedings. Accordingly, the Corporation’s estimate will change from time-to-time, and actual losses may be more or less than the current estimate. While the final outcome of legal cases, matters, and proceedings is inherently uncertain, based on information currently available, management 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. Based on the Corporation’s assessment as of June 30, 2019, 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 a defendant in a punitive class action complaint, filed in February 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 (“Plaintiffs”) against Banco Popular de Puerto Rico and other financial institutions with insurance agency subsidiaries in Puerto Rico (“Defendants”). 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. In March 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 Commissioner's Office. All other co-defendants filed motions to dismiss the complaint and opposed the request for preliminary injunctive relief. 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. In July 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 without prejudice. In August 2017, Plaintiffs filed an appeal before the Puerto Rico Court of Appeals and FirstBank Puerto Rico and other co-defendants filed their Oppositions to Plaintiffs’ appeal. In March 2018, the Court of Appeals entered a Judgment revoking the lower court’s Judgment. One co-defendant filed for reconsideration, which was denied, and all other co-defendants filed their respective Petitions of Certiorari before the Puerto Rico Supreme Court, which also denied review. Co-defendants have filed for reconsideration. All Motions for Reconsideration were denied, and the case was remanded to the Court of First Instance for the continuation of proceedings. A Class certification hearing scheduled for May 2, 2019 was changed to a status hearing. Parties discussed their respective positions, specifically that prior to celebrating any other hearing, it is imperative that the Court enters to resolve FirstBank’s suit seeking Declaratory Judgment. Memorandums of law regarding the validity of the Antilles Insurance policy endorsement were filed on June 3, 2019 in compliance with a court order. A preliminary injunction hearing is scheduled for September 2019.

Consolidation, Policy [Policy Text Block]	NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The Consolidated Financial Statements (unaudited) of First BanCorp. (the “Corporation”) have been prepared in conformity with the accounting policies stated in the Corporation’s Audited Consolidated Financial Statements included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Annual Report on Form 10-K”). Certain information and note disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted from these statements pursuant to the rules and regulations of the SEC and, accordingly, these financial statements should be read in conjunction with the Audited Consolidated Financial Statements of the Corporation for the year ended December 31, 2018, which are included in the 2018 Annual Report on Form 10-K. All adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the statement of financial position, results of operations and cash flows for the interim periods have been reflected. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the quarter and six-month period ended June 30, 2019 are not necessarily indicative of the results to be expected for the entire year.
New Accounting Pronouncements, Policy [Policy Text Block]	Adoption of New Accounting Requirements and Recently Issued but Not Yet Effective Accounting Requirements The Financial Accounting Standards Board (“FASB”) has issued the following accounting pronouncements and guidance relevant to the Corporation’s operations: Lease Accounting In February 2016, the FASB updated the FASB Accounting Standards Codification (“ASC” or the “Codification”) to replace ASC Topic 840, “Leases (Topic 840)” (“ASC Topic 840”), with new guidance for the financial reporting about leasing transactions. Under the new guidance, a lessee is required to recognize a right-of-use asset (“ROU”) and a lease liability for leases with lease terms of more than 12 months. Similar with the practice before the adoption of this guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily depend on its classification as a finance or operating lease. However, unlike previous guidance, which required the recognition of only capital leases on the balance sheet, the guidance requires both types of leases to be recognized on the balance sheet. The guidance also requires disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative information and additional information about the amounts recorded in the financial statements. The FASB issued an update in January 2018 providing an optional transition practical expedient under which an entity need not evaluate under new ASC Topic 842, “Leases” (“ASC Topic 842”), land easements that existed or expired before the entity’s adoption of ASC Topic 842 and were not previously accounted for as leases. In addition, the FASB issued an update in July 2018 that provides entities with an additional and optional transition method that allows entities to adopt the new standard prospectively as of the effective date, without adjusting comparative periods presented. Also, the amendments provide lessors with a practical expedient, by class of underlying asset, to not separate non lease components, subject to certain circumstances. Also in July 2018, the FASB issued an update that makes various technical corrections to clarify how to apply certain aspects of the new leases standard, such as reassessment of lease classification, variable lease payments that depend on an index or a rate, lease term and purchase options, and certain transition adjustments, among others. The guidance on leases took effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The update affected the Corporation’s consolidated financial statements since the Corporation has operating and lease arrangements for which it is a lessee. The new standard provides a number of optional practical expedients in transition. The Corporation adopted this guidance in 2019, and elected the optional transition approach to not apply the new lease standard in comparative periods presented and the package of practical expedients, which allows the Corporation not to reassess prior conclusions about lease classification and initial direct costs. The adoption of this standard in January 2019 resulted in the recognition of ROU assets and lease liabilities for operating leases of $ 59.6 million and $ 62.1 million, respectively, with the most significant impact from recognition of ROU assets and liabilities related to the operating leases for the Bank’s branches and automated teller machines (“ATMs”). The Corporation elected not to recognize ROU assets and lease liabilities that arise from short-term leases, primarily related to certain month-to-month ATM operating leases. Disclosures required by the standard have been included in Note 11 - Leases. Amortization of Premiums and Discounts on Callable Debt Securities In March 2017, the FASB updated the Codification to shorten the amortization period for certain purchased callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. With respect to securities held at a discount, the amendments do not require an accounting change; thus, the discount continues to be amortized to maturity. The amendments in this update more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. In most cases, market participants price securities to the call date that produces the worst yield when the coupon is above current market rates (that is, the security is trading at a premium) and price securities to maturity when the coupon is below market rates (that is, the security is trading at a discount) in anticipation that the borrower will act in its economic best interest. As a result, the amendments more closely align interest income recorded on bonds held at a premium or a discount with the economics of the underlying instrument. For public business entities, the amendments in this update took effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this guidance during the first quarter of 2019, did not have a material effect on the Corporation’s consolidated statement of financial condition or results of operations. As of June 30, 2019, the Corporation does not have callable debt securities held at a premium. Derivatives and Hedging In August 2017, the FASB updated the Codification to: (i) expand hedge accounting for nonfinancial and financial risk components and amend measurement methodologies to more closely align hedge accounting with a company’s risk management activities; (ii) decrease the complexity of preparing and understanding hedge results by eliminating the separate measurement and reporting of hedge ineffectiveness; (iii) enhance transparency, comparability, and understanding of hedge results through enhanced disclosures and a change in the presentation of hedge results to align the effects of the hedging instrument and the hedged item; and (iv) reduce the cost and complexity of applying hedge accounting by simplifying the manner in which assessments of hedge effectiveness may be performed. This update took effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance requires companies to apply requirements to existing hedging relationships on the date of adoption, and the effect of the adoption should be reflected as of the beginning of the fiscal year of adoption. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 815, Derivative and Hedging,” to provide further clarification on previously issued updates. This Update addresses the following areas of the guidance: (i) partial-term fair value hedges; (ii) fair value hedge basis adjustments; (iii) not-for-profit entities and private companies; and (v) first-payments-received cash flow hedging. As June 30, 2019, all of the derivatives held by the Corporation were considered economic undesignated hedges. The adoption of this guidance during the first quarter of 2019 did not have an effect on the Corporation’s consolidated statement of financial condition or results of operations. Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income In February 2018, the FASB updated the Codification to provide entities with an option to reclassify to retained earnings, tax effects that were stranded in accumulated other comprehensive income, pursuant to the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). This guidance took effect for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This guidance could be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the corporate tax rate in the Tax Act is recognized. The adoption of this guidance during the first quarter of 2019 did not have an effect on the Corporation’s consolidated financial statements. Accounting for Financial Instruments – Credit Losses In June 2016, the FASB updated the Codification to introduce new guidance for the accounting for credit losses. The guidance includes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The CECL model will apply to: (1) financial assets subject to credit losses and measured at amortized cost; and (2) certain off-balance sheet credit exposures. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees, and net investments in leases, as well as reinsurance and trade receivables. Upon initial recognition of the exposure, the CECL model requires an entity to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses (“ECL”) should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating ECL. The guidance does not prescribe a specific method to make the estimate, so its application will require significant judgment. Generally, upon initial recognition of a financial asset, the estimate of the ECL will be recorded through an allowance for credit losses (“ACL”) with an offset to current earnings. Subsequently, the ECL will need to be reassessed each period, and both negative and positive changes to the estimate will be recognized through an adjustment to the allowance for loan and lease losses and earnings. The guidance amends the current OTTI model for available-for-sale debt securities. The new available-for-sale debt security model will require an estimate of ECL only when the fair value is below the amortized cost of the asset. The length of time the fair value of an available-for-sale debt security has been below the amortized cost will no longer affect the determination of whether a credit loss exists. As such, the new available-for-sale debt security model is not an OTTI model. In addition, credit losses on available-for-sale debt securities will now be limited to the difference between the security’s amortized cost basis and its fair value. The available-for-sale debt security model will also require the use of an allowance to record ECL (and subsequent recoveries). The purchased financial assets with credit deterioration (“PCD”) model will apply to purchased financial assets (measured at amortized cost or available-for-sale) that have experienced more than insignificant credit deterioration since origination. This represents a change from the scope of what are considered purchased credit-impaired assets under today’s model. In contrast to the accounting for originated or purchased assets that do not qualify as PCD, the initial estimate of ECL for a PCD will be recognized through an allowance for loan and lease losses with an offset to the cost basis of the related financial asset at acquisition ( i.e. , there will be no effect on net income at initial recognition). Subsequently, the accounting will follow the applicable CECL or available-for-sale debt security impairment model with all adjustments of the allowance for loan and lease losses recognized through earnings. Beneficial interests classified as held-to-maturity or available-for-sale will need to apply the PCD model if the beneficial interest meets the definition of PCD or if there is a significant difference between contractual and expected cash flows at initial recognition. In general, the new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. However, prospective application is required for PCD assets previously accounted for under ASC Topic 310-30, “Receivables,” and for debt securities for which an OTTI was recognized prior to the date of adoption. This guidance also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, public business entities will need to disclose, among other things, the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination ( i.e. , by vintage year). In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments- Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” in part to clarify the accounting treatment for the measurement of credit losses under ASC 326, “Financial Instruments.” This update provides clarification on the following areas of the guidance: (i) accrued interest; (ii) recoveries; (iii) projections of the interest rate environment; (iv) consideration of prepayments; and (v) other topics. In May 2019, the FASB issued an update that allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that: (i) were previously recorded at amortized cost and (ii) are within the scope of ASC Topic 326-20, “Financial Instruments – Credit Losses Measured at Amortized Cost,” if the instruments are eligible for the fair value option under ASC Topic 825-10, “Financial Instruments-Overall.” The guidance will be effective for public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption of the guidance is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Corporation developed a project plan in order to comply on a timely basis with the implementation of this new CECL impairment model and expects to adopt the guidance in the first quarter of 2020. The implementation process is being conducted by a working group composed of members from multiple areas across the Corporation and includes the selection and development of loss forecasting models, evaluation of technical accounting topics, updates to the Corporation’s allowance documentation, reporting processes and related internal controls, and evaluation of the overall operational readiness for the adoption. This process is expected to continue for the reminder of 2019. Currently, the Corporation is in the process of conducting and validating the results of parallel runs pursuant to the provisions of the CECL standard alongside the Corporation’s current processes for estimation of the allowance for loan and leases losses. The Corporation’s approach for estimating ECL for applicable loans and debt securities includes the following key components:  An initial forecast period (“reasonable and supportable period”) between 2 and 4 years, varying by portfolio geographies, for all portfolio segments and classes of financing receivables and off-balance-sheet credit exposures. This period reflects management’s expectations of losses based on forward-looking economic scenarios over that time.  A historical loss forecast period covering the remaining contractual life, adjusted for prepayments, by portfolio segments and classes of financing receivables based on the change in key historic economic variables during representative historical expansionary and recessionary periods.  A reversion period connecting the initial loss estimate covered by the reasonable and supportable period to historical loss forecast based on economic conditions at measurement date.  The Corporation will utilize discounted cash flow (“DCF”) methods to measure credit impairment for loans modified in a TDR, unless they are collateral dependent and measured based on the fair value of the collateral. The DCF methods would provide the estimated life-time credit losses.  For available-for-sale and held-to-maturity securities, the Corporation will utilize the DCF methods to measure the allowance for credit losses. The Corporation expects an overall increase in the ACL, with a higher increase for longer duration residential mortgage loan portfolios. We will recognize an ACL for available-for-sale and held-to-maturity securities. The ACL on available-for-sale securities will be subject to a limitation based on the fair value of the security. We continue to evaluate the results of modeled loss estimates and continue to conduct refinements to the approach, including considerations around imprecision and uncertainty, based on management’s judgment on the inherent risks around processes and assumptions in estimating the ACL. The amount of the change in the ACL will be impacted by the Corporation’s loan portfolio and debt securities mix, credit quality, economic conditions and forecasts at the adoption date. The Corporation expects to have a cumulative-effect adjustment to retained earnings for the change in the ACL, which will impact capital. An increase in the ACL will result in a reduction to the Corporation’s and banking subsidiary regulatory capital ratios, however, as of this date, we are not able to provide a precise estimate of the impact. Banking regulatory agencies have permitted institutions to limit the initial regulatory capital day-one impact by allowing a three-year phase in period for this impact, on a straight-line basis. The working group provides periodic updates to the Corporation’s CECL Management Committee, which has oversight responsibilities for the implementation efforts. The CECL Management Committee also reports to the Corporation’s Board of Directors Audit Committee progress of the implementation plan. Subsequent Measurement of Goodwill In January 2017, the FASB updated the Codification to simplify the subsequent measurement of goodwill by eliminating Step 2 from the current two-step goodwill impairment test. This guidance provides that a goodwill impairment test shall be conducted by comparing the fair value of a reporting unit with its carrying amount. Entities must recognize an impairment charge for goodwill equal to the excess of the carrying amount over the reporting unit’s fair value. Entities have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The effect of this guidance will depend upon the performance of the reporting units that have goodwill and the market conditions affecting the fair value of each reporting unit going forward. Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB updated the Codification and amended ASC Topic 820, “Fair Value Measurement and Disclosures,” to add, remove, and modify fair value measurement disclosure requirements. The disclosure requirements that are removed for public entities include: (i) transfers between Level 1 and Level 2 of the fair value hierarchy; (ii) the policy for determining when transfers between any of the three levels have occurred; and (iii) the valuation processes used for Level 3 measurements. The disclosure requirements that are modified for public entities include: (i) for certain investments in entities that calculate the net asset value, revisions to require disclosures about the timing of liquidation and lapses of redemption restrictions, if the latter has been communicated to the reporting entity; and (ii) revisions to clarify that the disclosure of Level 3 measurement uncertainty should communicate information about the uncertainty as of the balance sheet date. The additional or new disclosure requirements include: (i) the changes in unrealized gains and losses for the period must be included in other comprehensive income for recurring Level 3 instruments held as of the balance sheet date; and (ii) the range and weighted average of significant unobservable inputs used for Level 3 measurements must be disclosed, but an entity has the option to disclose other quantitative information in place of the weighted average to the extent that it would be a more reasonable and rational method to reflect the distribution of certain unobservable inputs. This update is effective for all entities in fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any of the removed or modified disclosures immediately even if adoption of the new disclosures is delayed until the effective date. In the third quarter of 2018, the Corporation early adopted the disclosure requirements that were removed or modified by this guidance. Collaborative Arrangements In November 2018, the FASB issued new guidance to clarify the interaction between Collaborative Arrangements (“ASC Topic 808”) and Revenue from Contracts with Customers (“ASC Topic 606”) standards. The guidance (i) clarifies that certain transactions between collaborative arrangement participants should be accounted for under the ASC Topic 606 guidance; (ii) adds unit of account guidance to ASC Topic 808 to align with ASC Topic 606; and (iii) clarifies presentation guidance for transactions with a collaborative arrangement participant that is not accounted for under ASC Topic 606. The guidance is effective for annual reporting periods beginning after December 1, 2019, including interim reporting periods within these annual reporting periods, with early adoption permitted. The Corporation does not expect the adoption of this standard to have a material effect on its consolidated financial statements.
Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]	The Corporation commences the foreclosure process on residential real estate loans when a borrower becomes 120 days delinquent in accordance with the guidelines of the Consumer Financial Protection Bureau (“CFPB”). Foreclosure procedures and timelines vary depending on whether the property is located in a judicial or non-judicial state. Judicial states ( i.e. , Puerto Rico, Florida and the USVI) require the foreclosure to be processed through the state’s court while foreclosure in non-judicial states ( i.e. , the BVI) is processed without court intervention. Foreclosure timelines vary according to local jurisdiction law and investor guidelines. Occasionally, foreclosures may be delayed due to, among other reasons, mandatory mediations, bankruptcy, court delays and title issues.
Troubled Debt Restructuring [Policy Text Block]	The Corporation’s loss mitigation programs for residential mortgage and consumer loans can provide for one or a combination of the following: movement of interest past due to the end of the loan, extension of the loan term, deferral of principal payments and reduction of interest rates either permanently or for a period of up to six years (increasing back in step-up rates). Additionally, in certain cases, the restructuring may provide for the forgiveness of contractually-due principal or interest. Uncollected interest is added to the end of the loan term at the time of the restructuring and not recognized as income until collected or when the loan is paid off. These programs are available only to those borrowers who have defaulted, or are likely to default, permanently on their loans and would lose their homes in a foreclosure action absent some lender concession. Nevertheless, if the Corporation is not reasonably assured that the borrower will comply with its contractual commitment, properties are foreclosed. Prior to permanently modifying a loan, the Corporation may enter into trial modifications with certain borrowers. Trial modifications generally represent a six-month 3.0 million of residential mortgage loans as TDRs that were participating in or had been offered a trial modification. For the commercial real estate, commercial and industrial, and construction loan portfolios, at the time of a restructuring, the Corporation determines, on a loan-by-loan basis, whether a concession was granted for economic or legal reasons related to the borrower’s financial difficulty. Concessions granted for loans in these portfolios could include: reductions in interest rates to rates that are considered below market; extension of repayment schedules and maturity dates beyond original contractual terms; waivers of borrower covenants; forgiveness of principal or interest; or other contractual changes that are considered to be concessions. The Corporation mitigates loan defaults for these loan portfolios through its collection function. The function’s objective is to minimize both early stage delinquencies and losses upon default of loans in these portfolios. In the case of the commercial and industrial, commercial mortgage, and construction loan portfolios, the Corporation’s Special Asset Group (“SAG”) focuses on strategies for the accelerated reduction of non-performing assets through note sales, short sales, loss mitigation programs, and sales of OREO. In addition, the Corporation extends, renews, and restructures loans with satisfactory credit profiles. Many commercial loan facilities are structured as lines of credit, which generally have one-year terms and, therefore, are required to be renewed annually. Other facilities may be restructured or extended from time to time based upon changes in the borrower’s business needs, use of funds, and timing of completion of projects, and other factors. If the borrower is not deemed to have financial difficulties, extensions, renewals, and restructurings are done in the normal course of business and not considered concessions, and the loans continue to be recorded as performing.

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.

Servicing Assets and Servicing Liabilities at Fair Value, Assumptions Used to Estimate Fair Value, Qualitative Information

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

If there is no legal surplus reserve sufficient to cover such balance in whole or in part, the outstanding amount must be charged against the capital account and the Bank cannot pay dividends until it can replenish the legal surplus reserve to an amount of at least 20% of the original capital contributed.
