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, 2016. 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 th e 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, 2016, which are included in the Corporation ’s 2016 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 nine -month period ended September 30, 201 7 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 pronounc ements and guidance relevant to the Corporation’s operations: In May 2014, the FASB updated the Accounting Standards Codification (the “Codification” or the “ASC”) to create a new, principles-based revenue recognition framework. The Update is the culminat ion of efforts by the FASB and the International Accounting Standards Board to develop a common revenue standard for GAAP and International Financial Reporting Standards. The core principal of the guidance is that an entity should recognize revenue to depi ct the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance describes a 5-step process that entities can apply to achieve the core principle of revenue recognition and requires disclosures sufficient to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and the significant judgments used in determining that information. The new framework is effective for public business entities, with certain exceptions that are not SEC registrants provided recently by the SEC staff, for annual periods beginning after December 15 , 2017, including interim periods within those reporting periods, as a result of the FASB’s amendment to the standard to defer the effective date by one year. Early adoption is permitted for interim periods beginning after December 15, 2016. The Corporation plans to adopt the revenue recognition guidance on January 1, 2018 using the modified retrospective method of adoption. The Corporation’s implementation efforts include the identification of revenue within the scope of the guidance, as we ll as the evaluation of revenue contracts and related accounting policies. Because the amended guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP, the Corpor ation’s has scoped out the majority of its revenue streams. While in scope of the new guidance, the Corporation does not expect a material change in the timing or measurement of revenues related to deposit fees. The Corporation has concluded that its credi t cardholder fees and mortgage servicing fees standards are not subject to the new standard. Nonetheless, the Corporation continues to evaluate other revenue streams such as interchange fees, merchant fees and insurance commissions but does not expect material chang es in the timing of when revenues are recognized upon the adoption of this standard. In March 2016, the FASB updated the Codification to simplify certain aspects of the accounting for share-based payment transactions. The main provisions in this Update include: (i) recognition of all tax benefits and tax deficiencies (including tax benefits of dividends on share-base payment awards) as income tax e xpense or benefit in the income statement, (ii) classification of the excess tax benefit along with other income tax cash flows as an operating activity, (iii) an entity-wide accounting policy election to either estimate the number of awards that are expec ted to vest (current GAAP) or account for forfeitures when they occur, (iv) a threshold to qualify for equity classification that permits withholding up to the maximum statutory tax rate in the applicable jurisdictions, and (v) classification of cash paid by an employer as a financing activity when the payment results from the withholding of shares for tax withholding purposes. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Corporation adopted the provisions during the first quarter of 2017 without any material impact on the Corporation’s consolidated financial statements. In March 2016, the FASB updated the Codification to require an equity method investor to add the cost of acquiring an additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. Also, this Update requires that an entity that has an available-for sale equity security that becomes qua lified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degr ee of influence that result in the adoption of the equity method. The adoption of this guidance during the first quarter of 2017 did not have an impact on the Corporation’s consolidated financial statements. In June 2016, the FASB updated the Codifica tion to introduce new guidance for the accounting for credit losses on instruments that includes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses . The Corporation ha s developed a transition roadmap in order to comply with the timely implementation of this new accounting framework. The Corporation has created a Working Group with members from multiple areas across the organization that is responsible for assessing the impact of the standard, evaluating interpretative issues, and evaluating the current credit loss models against the new guidance to determine any changes necessary and other related implementation activities. The Working Group provides periodic updates to the Corporation’s CECL Management Committee, which has oversight responsibilities for the implementation efforts. In October 2016, the FASB updated the Codification to modify the criteria used by a reporting entity when determining if it is the primar y beneficiary of a variable interest entity (“VIE”) when the entities are under common control and the reporting entity has indirect interests in the VIE through related parties. If the reporting entity meets the first criteria in that it has the power to direct the activities of the VIE that are most significant to its economic performance, it is required to consider all interests held indirectly through related entities on a proportionate basis in determining if it meets the second criterion, that is, the obligation to absorb losses of the VIE or the right to receive benefits from it that are potentially significant to the VIE. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2016, inc luding interim periods within those fiscal years. The adoption of this guidance did not have an impact on the Corporation’s consolidated financial statements. In March 2017, the FASB updated the Codification to shorten the amortization period for cer tain 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. Under current GAAP, premiums and discounts on callable debt securities generally are amortized to the maturity date. An entity must have a large number of similar loans to consider estimates of future pri ncipal prepayments when applying the interest method. However, an entity that holds an individual callable debt security at a premium may not amortize that premium to the earliest call date. If that callable debt security is subsequently called, the entity records a loss equal to the unamortized premium. 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 particip ants 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 instr ument. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of this guidance is not expected to have a material impact on the Corporation’s statement of financial condition or results of operations. As of September 30, 2017, the Corporation had $ 4.2 million of callable debt securities held at a premium (unamortized premium of $ 0.1 million). In May 2017, the FASB updated the codification to reduce the cost and complexity when applying ASC Topic 718 and standardize the practice of applying Topic 718 to financial reporting. Topic 718 prescribes the accounting treatment of a modification in the terms or conditions of a share- based payment award. The guidance clarifies what changes would qualify as a modification. This was done by better defining what does not constitute a modification. In order for a change to a share-based arrangement to not require Topic 718 modification tre atment, all of the following must be met : (i) the fair value (or alternative measurement method used ) of the modified award equals the fair value (or alternative measurement method used ) of the original award immediately before the original award is modifi ed, (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified , and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under this Update. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. The amendments in this Update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The Corporation’s Omnibus Plan provides for equity based compensation incentives through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, ca sh-based awards and other stock-based awards. If any change occurs in the future to awards issued under the Omnibus Plan, the Corporation will evaluate it under this guidance. In August 2017, the FASB updated the Codification to: (i) expand hedge acc ounting 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 elim inating the separate measurement and reporting of hedge ineffectiveness, (iii) enhance transparency, comparability, and understanding of hedge results through enhanced disclosures and changing the presentation of hedge results to align the effects of the h edging 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 is effective for fiscal years, and interim perio ds within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The guidance requires companies to apply requirements to existing hedging relationships on the date of adoption, and the effect of the adoption should be reflecte d as of the beginning of the fiscal year of adoption. As of September 30, 2017, all of the derivatives held by the Corporation were considered economic undesignated hedges. The adoption of this guidance is not expected to have a material impact on the Corp oration’s statement of financial condition or results of operations.

NATURAL DISASTERS

Text Block [Abstract]
Natural Disasters [Text Block]	NOTE 2 – NATURAL DISASTERS AFFECTING FIRST BANCORP. IN THIRD QUARTER 2017 Two strong hurricanes affected the Corporation’s service areas during the third quarter of 2017. Early in September, Hurricane Irma hit ground through the eastern Caribbean as a Category 5 storm affecting several islands, including the U.S. Virgin Islands of St. Thomas and St. John and Tortola in the British Virgin Islands, with lesser impacts on St. Croix and Puerto Rico. After hitting t he eastern Caribbean, Hurricane Irma made landfall along Florida’s southwest shoreline. Two weeks after Hurricane Irma sideswiped Puerto Rico, Hurricane Maria made landfall in the south east corner of Puerto Rico as a Category 4 storm and exit ed on the no rthern coast at a point between the cities of Arecibo and Barceloneta after battering other islands in the Caribbean, including the U.S. Virgin Island of St. Croix. These storms caused, among other things, widespread property damage, flooding, power outag es, and water and communication services interruptions , and severely disrupted normal economic activity in all of these regions. The following summarizes the more significant financial repercussions of these natural disasters for the Corporation and for its major subsidiary, FirstBank. Credit Quality and Allowance for Loan and Lease Losses The Corporation established a $ 66.5 million allowance for loan and lease losses in the third quarter of 2017 directly related to the initial estimate, based on availabl e information, of inherent losses resulting from the impact of the recent storms. As the Corporation acquires additional information on overall economic prospects in the affected areas together with loan officers’ further assessments of the impact on individual borrowers, the loss estimate will be revised as needed, and these revisions could be material. The Corporation’s approach to estimating the storms’ impact on credit quality is presented in Note 8 – “ Allowance for Loan and Lease Losses .” Interr uptions in regular collection efforts caused by Hurricanes Irma and Maria adversely affected the Corporation’s non-performing loan statistics. Non-performing residential mortgage loans increased in the third quarter by $ 23.2 million to $178.5 million as o f September 30, 2017 and non-performing consumer loans and finance leases increased in the third quarter by $ 5.4 million to $ 26.5 million as of September 30, 2017. Refer to Note 7 – “ Loans Held For Investment ” for additional information about early delinq uency statistics and payment deferral programs established by the Corporation to assist individuals affected by the recent storms. Disaster Response Plan Costs, Casualty Losses and Related Insurance The Corporation implemented its disaster response plan as these storms approached its service areas. To operate in disaster response mode, the Corporation incurred expenses for, among other things, buying diesel and generators for electric power, debris r emoval, security matters, and emergency communications with customers regarding the status of Bank operations. The disaster response plan costs, combined with payroll and rental costs during the idle time caused by the storms , totaled $ 2. 9 million as of S eptember 30, 2017 , including $ 0.6 million in donations and other storm relief efforts and employee assistance. The Corporation will incur additional costs through the end of 2017 as the Corporation addresses ongoing operation al issues. The Corporation mai ntains insurance for its disaster response costs, as well as for certain revenue los t through business interruption . The Bank was able to resume operations in Puerto Rico within a week after Hurricane Maria made landfall, but with some limitations . C ertain of the Corporation’s facilities and their contents were damaged by these storms. The Corporation has recognized asset impairments of approximately $0.6 million as of September 30, 2017, an d the Corporation may identify additional impairments throug h the end of 2017. The Corporation maintains insurance policies for casualty losses that provide for replacement value coverage. Management believes, based on its understanding of the insurance coverages, that recovery of $2.9 million of the $ 3.5 mil lion above-mentioned costs and asset impairments identified as of September 30, 2017 is probable. A ccordingly, a receivable of $ 2.9 million was included in “O ther assets ” as of September 30, 2017 for the expected recovery . The impairments, recoverable exp enses and expected recoveries are included as part of “Other non-interest income” in the statement of (loss) income. 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 agreement on the Corporation’s claims with the insurance carriers.

EARNINGS PER COMMON SHARE	NOTE 3 – EARNINGS PER COMMON SHARE The calculations of earnings (loss) per common share for the quarters and nine-month periods ended September 30, 2017 and 2016 are as follows: Quarter Ended Nine-Month Period Ended September 30, September 30, 2017 2016 2017 2016 (In thousands, except per share information) Net (loss) income $ (10,752) $ 24,074 $ 42,787 $ 69,371 Less: Preferred stock dividends (669) - (2,007) - Net (loss) income attributable to common stockholders $ (11,421) $ 24,074 $ 40,780 $ 69,371 Weighted-Average Shares: Average common shares outstanding 214,187 212,927 213,812 212,682 Average potential dilutive common shares - 3,651 2,322 2,577 Average common shares outstanding - assuming dilution 214,187 216,578 216,134 215,259 (Loss) earnings per common share: Basic $ (0.05) $ 0.11 $ 0.19 $ 0.33 Diluted $ (0.05) $ 0.11 $ 0.19 $ 0.32 Earnings (loss) per common share is computed by dividing net income (loss) attributable to comm on stockholders by the weighted- average number of common shares issued and outstanding. Net income (loss) attributable to common stockholders represents net income (loss) adjusted for any preferred stock dividends, i ncluding any dividends declared, and any cumulative dividends related to the current dividend period that have not been declared as o f 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 common stock issuable under the assumed exercise of sto ck options, unvested shares of restricted stock that do not contain non-forfeitable dividend rights, and outstanding warrants using the treasury stock method. This method assumes that the potential dilutive common shares are issued and outstanding and the proceeds from the exercis e, 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. Stock options, unvested shares of rest ricted stock that do not contain non-forfeitable dividend rights, and outstanding warrants 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. Warrants outstanding to purchase 1,285,899 shares of co mmon stock and 1,815,904 unvested shares of restricted stock that do not contain non-forfeitable dividend rights were excluded from the computation of diluted earnings per share for the quarter ended September 30, 2017 because the Corporation reported a ne t loss attributable to common stockholders and their inclusion would have an antidilutive effect. Stock options not included in the computation of outstanding shares because they were antidilutive amounted to 34,989 as of September 30, 2016 .

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	9 Months Ended
	Sep. 30, 2017
STOCK-BASED COMPENSATION	NOTE 4 – STOCK-BASED COMPENSATION As of January 21, 2007, the Corporation’s 1997 stock option plan expired and no additional awards could be granted under that plan. A ll outstanding awards granted under this plan continued in full force and effect since then, subject to their original terms. No awards of shares could be granted under the 199 7 stock option plan as of its expiration . During the first quarter of 2017, all of the remaining outstanding awards granted under the 1997 stock option plan expire d . The activity of stock options granted under the 1997 stock option plan for the nine-month period ended September 30, 2017 is set forth below: Weighted-Average Remaining Aggregate Number of Weighted-Average Contractual Term Intrinsic Value Options Exercise Price (Years) (In thousands) Beginning of period outstanding and exercisable 34,989 $ 138.00 Options expired (34,989) 138.00 End of period outstanding and exercisable - $ - - $ - 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 c ommon s tock reserved for issu ance under the Omnibus Plan, extend the term of the Omni bus Plan to May 24, 2026 and re-approve the material terms of the performance goals under the Omnibus Plan for purposes of Section 162(m) of the U.S. Internal Revenue Code of 1986, as amende d. 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 September 30, 2017, 7,713,767 authorized shares of common stock were available for issuanc e under the Omnibus Plan. The Corporation’s Board of Directors, based on the recommendation of the Corporation’s Compensation 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. Under the Omnibus Plan , during the first nine months of 2017, the Corporation awarded to its independent directors 140,360 shares of restricted stock that ar e subject to a one-year vesting period . In addition, during the first nine months of 2017, the Corporation awarded 951,332 shares of restricted stock to employees subject to vesting period s that range from 1 to 2 years. Include d in those 951,332 shares of restricted stock were 838,332 shares granted in the first quarter of 2017 to certain senior officers consistent with the requirements of the Troubled Asset Relief Program (“TARP”) Interim Final Rule, which permit TARP recipient s to grant “long-term restricted stock” without violating the prohibition on paying or accruing a bonus payment , subject to limits on value and certain vesting and non-transferability requirements. On May 10, 2017, the United States Department of the Trea sury (the “U.S. Treasury”) announced that it had sold all of its remaining 10,291,553 shares of the Corporation’s common stock. As a result of the U.S. Treasury’s sale, the Corporation is no longer subject to the compensation-related restrictions under TARP, w hich substantially limited the Corporation’s ability to award short-term and long-term incentives to the Corporation’s executives, and the Corporation’s senior officers are no longer subject to the transferability restriction s on their shares of restricted stock . However, since the U.S. Treasury did not recover the full amount of its original investment under TARP, the senior officers forfeited 2,370,571 of their outstanding shares of restricted stock, resulting in a reduction in the number of common shar es outstanding. The U.S. Treasury continues to hold a warrant to purchase 1,285,899 shares of the Corporation’s common stock. The Corporation accounted for the restricted stock that it granted in 2017 prior to the U.S. Treasury’s sale of its shares at a discount from the market price of the Corporation’s outstanding common stock on the date of the grant. For the 838,332 shares of restricted stock granted subject to the TARP requirements, the market price was discounted assuming that 50 % of the shares of restricted stock wou ld become freely transferable and the remaining 50 % would be forfeited , resulting in a fair value of $ 2.71 for each share of restricted stock granted under TARP requirements . Since the assumption was correct, the forfeiture resulting from the U.S. Treasury’s sale did not have an impact o n the Corporation’s operating results . Also, the Corporation used empirical data to estimate employee terminations; separate groups of employees that have similar historical exercise behavior were considered separately for v aluation purposes. The following table summarizes the restricted stock activity in the first nine months of 2017 under the Omnibus Plan: Nine-Month Period Ended September 30, 2017 Number of shares Weighted-Average of restricted Grant Date stock Fair Value Non-vested shares at beginning of year 4,178,791 $ 2.58 Granted 1,091,692 3.30 Forfeited (1) (2,404,223) 2.33 Vested (2) (1,050,356) 3.57 Non-vested shares at September 30, 2017 1,815,904 $ 2.76 (1) Includes 2,370,571 of outstanding shares of restricted stock, subject to TARP requirements, that were forfeited as a result of the U.S. Treasury's sale of its remaining shares of the Corporation's common stock. (2) Includes 743,021 shares of restricted stock released from TARP restrictions. For the quarter and nine -month period ended September 30, 201 7 , the Corporation recognized $ 1.0 million and $ 3.0 million, respectively, of stock-based compensation expense related to restricted stock awards, compared to $ 1.0 million and $ 2.9 million for the same periods in 2016, respectively. As of September 30, 2017, there was $ 4.0 million of total unrecognized compensation cost related to non-vested shares of restricted stock. The weighted average period over which the Corporation expects to recogni ze such cost is 1.2 years. During the first nine months of 2016, 130,873 shares of restricted stock were awarded to the Corporation’s independent directors subject to a one-year vesting period. Also, during the first nine months of 2016 , the Corporatio n awarded 1, 794 , 702 shares of restricted stock to employees subject to vesting period s that range from 2 to 3 years. Included in those 1,7 94 , 702 shares of restricted stock were 1,546,137 shares granted to certain senior officers consistent with the require ments of TARP. As explained above, the Corporation is no longer subject to the compensation-related restrictions under TARP as a result of the U.S. Treasury’s sale of its remaining shares of the Corporation’s common stock. The fair value of the shares of restricted stock granted in the first nine months of 2016 was based on the market price of the Corporation’s outstanding common stock on the date of the grant. For the 1,546,137 shares of restricted stock granted under the TARP requirements, the market price was discounted due to the post-vesting restrictions . For purposes of determining the awards’ fair value, the Corporation assumed that 50 % of the shares of restricted stock would become freely transferable and the remaining 50 % will be forfeited, res ulting in a fair value of $ 1.43 for restricted shares granted under the TARP requirements. Stock-based compensation accounting guidance requires the Corporation to reverse compensation expense for any awards that are forfeited due to employee or direc tor turnover. Quarterly changes in the estimated forfeiture rate may have a significant effect on share-based compensation, as the effect of adjusting the rate for all expense amortization is recognized in the period in which the forfeiture estimate is cha nged. If the actual forfeiture rate is higher than the estimated forfeiture rate, then 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 f orfeiture rate is lower than the estimated forfeiture rate, an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase in the expense recognized in the financial statements. The estimated forfeiture rate did not chang e as a result of the restricted shares forfeited in connection with the aforementioned U.S. Treasury’s sale of the Corporation’s common stock. Approximately $ 48 thousand of compensation expense was reversed during 2017 related to forfeitures upon resignati on of two of the Corporation’s independent directors. Also, under the Omnibus Plan, effective April 1, 2013, the Corporation’s Board of Directors determined to increase the salary amounts paid to certain executive officers pri marily by paying the increased salary amounts in the form of shares of the Corporation’s common stock, instead of cash. During the first nine months of 201 7 , the Corporation issued 427,940 shares of common stock (first nine months of 2016 – 629,476 shares) with a weighted average market value of $ 5.88 (first nine months of 2016 – $ 3.60 ) as salary stock compensation. This resulted in a compensation expense of $ 2.5 million recorded in the first nine months of 201 7 (first nine months of 2016 – $ 2.2 million) . For the first nine months of 201 7 , the Corporation withheld 143,509 shares (first nine months of 2016 – 189,604 shares) from the common stock paid to certain senior officers as additional compensation and 243,102 shares of restricted stock that vested du ring the first nine months of 201 7 (first nine months of 2016 – 65,498 ) to cover employees’ payroll and income tax withholding liabilities; these shares are held as treasury shares. The Corporation paid any fractional share of salary stock that the officer was entitled to in cash. In the consolidated financial statements, the Corporation treats shares withheld for tax purposes as common stock repurchases . On June 29, 2017, upon the recommendation of the Corporation’ s Compensation and Benefits Committee, the Corporation’s Board of Directors approved a new executi ve compensation program that, as of July 1, 2017, applies to the Corporation’s executive officers as a result of the aforementioned sale by the U.S. Treasury of its remaining shares of the Corporation’s common stock. The new compensation program for executive officers maintains the current levels of cash salary through calendar year 2017. The payment of additional salary amounts currently paid in the form of stock will continue through the s econd quarter of 2018 and will be eliminated at such time. In addition, as a long-term incentive, the new compensation program provides a variable pay opportunity for long-term performance through a combination of performance shares and restricted stock. The aggregate value of the performance shares and restricted stock will be determined based upon a qualitative assessment of the achievement by executives of their individual goals for the prior year and at three different possible aggregate equity valuation levels (minimum threshold, target and maximum). The Corporation’s Board of Directors has determined that 60 % of the long-term incentive award value based upon prior year performance will be in performance shares and 40 % will be in restricted stoc k with the following terms: Performance Shares— the payout of the performance shares will depend upon the achievement of a pre-established corporate tangible book value per share goal at the end of a three-year period. All of the performance shares will vest if performance is at the pre-established performance goal level or above. To the extent that performance is below the target but at or above a pre-defined minimum threshold, a proportionate amount of the performance shares will vest. No performance sh ares will vest if performance is below the threshold. Restricted Stock—Restricted stock will vest over a three-year period as follows: fifty percent ( 50 %) of the shares will vest on the second anniversary date of the grant of the award and the remaining f ifty percent ( 50 %) will vest on the third anniversary date of the grant of the award . The first awards of performance shares are e xpected to be made in early 2018.

The Corporation’s OTTI asses sment was concentrated mainly on private label mortgage-backed securities (“MBS”) and on Puerto Rico governm ent 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 o f 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 informat ion available about the financial condition of the issuer, credit ratings, the failure of the issuer to make scheduled principal or interest payments, recent legislation and government actions affecting the issuer’s industry and actions taken by the issuer to deal with the present economic climate ; Cha nges in the near term prospects of the underlying collateral of a security , if any, such as changes in default rates, loss severity given default , and significant changes in prepayment assumptions; and The level of cash flows generated from the underlying collateral , if any, supporting the principal and interest payments of the debt securities. T he Corporation recorded OTTI losses on available-for-sale debt securities as follows: Quarter Ended Nine-Month Period Ended September 30, September 30, 2017 2016 2017 2016 (In thousands) Total other-than-temporary impairment losses $ - $ - $ (12,231) $ (1,845) Portion of other-than-temporary impairment recognized in OCI - - - (4,842) Net impairment losses recognized in earnings (1) $ - $ - $ (12,231) $ (6,687) (1) For the nine-month periods ended September 30, 2017 and 2016, approximately $12.2 million and $6.3 million, respectively, of the credit impairment recognized in earnings consisted of credit losses on Puerto Rico Government debt securities that were sold in the second quarter of 2017, as further discussed below. For the nine-month period ended September 30, 2016, $0.4 million of the credit impairment recognized in earnings was associated with credit losses on private label MBS. The following tables summarize the roll-forward of credit losses on debt securities held by the Corporation for which a portion of an OTTI is recognized in OCI: Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit impairments Credit loss June 30, recognized in earnings recognized in earnings on reductions for September 30, 2017 on securities not securities that have been securities sold 2017 Balance previously impaired previously impaired during the period Balance (In thousands) Available-for-sale securities Private label MBS $ 6,792 $ - $ - $ - $ 6,792 Total OTTI credit losses for available-for-sale debt securities $ 6,792 $ - $ - $ - $ 6,792 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit loss December 31, recognized in earnings on reductions for September 30, 2016 securities that have been securities sold 2017 Balance previously impaired during the period Balance (In thousands) Available-for-sale securities Puerto Rico government obligations $ 22,189 $ 12,231 $ (34,420) $ - Private label MBS 6,792 - - 6,792 Total OTTI credit losses for available-for-sale debt securities $ 28,981 $ 12,231 $ (34,420) $ 6,792 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit impairments June 30, recognized in earnings recognized in earnings on September 30, 2016 on securities not securities that have been 2016 Balance previously impaired previously impaired Balance (In thousands) Available-for-sale securities Puerto Rico government obligations $ 22,189 $ - $ - $ 22,189 Private label MBS 6,792 - - 6,792 Total OTTI credit losses for available-for-sale debt securities $ 28,981 $ - $ - $ 28,981 Cumulative OTTI credit losses recognized in earnings on securities still held Credit impairments Credit impairments December 31, recognized in earnings recognized in earnings on September 30, 2015 on securities not securities that have been 2016 Balance previously impaired previously impaired Balance (In thousands) Available-for-sale securities Puerto Rico government obligations $ 15,889 $ - $ 6,300 $ 22,189 Private label MBS 6,405 - 387 6,792 Total OTTI credit losses for available-for-sale debt securities $ 22,294 $ - $ 6,687 $ 28,981 During the second quarter of 2017, the Corporation sold for an aggregate of $ 23.4 million three Puerto Rico Government available-for-sale debt securities, specifically bonds of the GDB and the Puerto Rico Public Buildings Authority, carried on its book at an amortized cost at the time of sale of $ 23.0 million (net of $34.4 million in cumulative OTTI impairment charges). This transaction resulted in a $ 0.4 million recovery from previous OTTI charge s reflected in the statement of (loss) income as part of “net gain on sale of investments.” Approximately $12.2 million of the cumulative OTTI charges on these securities was recorded in the first quarter of 2017. For the OTTI charge recorded in the first quarter of 2017, the Corporation considered revis ed estimates of recovery rates based on the latest available information about the Puerto Rico government’s financial condition, including the downgrade of credit ratings, and the revised fiscal plan published by the Puerto Rico government in March 2017. T he Corporation applied a discounted cash flow analysis to its Puerto Rico government debt securities in order to calculate the cash flows expected to be collected and to determine if any portion of the decline in market value of these securities was consid ered a credit-related other-than-temporary i mpairment. The analysis derived an estimate of value based on the present value of risk-adjusted cash flows of the underlying securities and included the following components: The contractual fu ture cash flows of the bonds were projected based on the key terms as set forth in the official statements for each security. Such key terms include, among others, the interest rate, amortization schedule, if any, and maturity date. The risk-adjusted cash flows were cal culated based on a probability of default analysis and recovery rate assumptions, including the weighting of different scenarios of ultimate recovery, considering the credit rating of each security. Co nstant monthly default rates were assumed throughout th e li fe of the bonds, which considered the respective security's credit rating as of the date of the analysis. The adjusted future cash flows were then discounted at the original effective yield of each investment based on the purchase price and expected risk-adjusted future cash flows as of the purchase date of each investment. The discounted risk-adjusted cash flow anal ysis for the three Pu erto Rico g overnment bonds mentioned above assumed a default probability of 100 %, as these three non-performing bonds had been in default since the third quarter of 2016. Based on this analysis, the C orporation recorde d in the first quarter of 2017 other -than-temporary credit-related impa irment charges amounting to $12.2 million, assuming recovery rates ranging from 1 5 % to 80 % ( with a weighted average of 4 1 %). In addition, during the first quarter of 2016 , the Corporation recorded a $0.4 million cre dit-related impairment loss associated with private label MBS, which are collateralized by fixed-rate mortgages on single-family residential properties in the United States. The interest rat es on these private-label MBS are variable, tied to 3-month LIBOR and limited to the weighted-average coupon of the underlying collateral. The underlying mortgages are fixed-rate, single-family loans with original high FICO scores (over 700 ) and moderate original loan-to-value ratios (under 80 %), as well as moderate deli nquency 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 l oss component was reflected in earnings. Significant assumptions in the valuation of the private label MBS were as follows: As of As of September 30, 2017 December 31, 2016 Weighted Weighted Average Range Average Range Discount rate 14.2% 14.2% 14.1% 12.88% - 14.43% Prepayment rate 16.5% 12.0% - 29.0% 13.8% 6.5% - 22.5% Projected Cumulative Loss Rate 4% 0.1% - 7.1% 4% 0.2% - 8.6% Investment s Held to Maturity The amortized cost, gross unrealized gains and losses, approximate fair value, weighted-average yield and contractual maturities of investment securities held to maturity as of September 30, 2017 and December 31, 2016 were as follows: September 30, 2017 Amortized cost Fair value Weighted average yield% Gross Unrealized gains losses Puerto Rico Municipal Bonds: After 1 to 5 years $ 3,853 $ - $ 146 $ 3,707 5.38 After 5 to 10 years 39,523 - 2,775 36,748 5.27 After 10 years 107,251 - 17,581 89,670 4.88 Total investment securities held to maturity $ 150,627 $ - $ 20,502 $ 130,125 4.99 December 31, 2016 Amortized cost Fair value Weighted average yield% Gross Unrealized gains losses Puerto Rico Municipal Bonds: After 1 to 5 years $ 1,136 $ - $ 20 $ 1,116 5.38 After 5 to 10 years 10,741 - 718 10,023 4.47 After 10 years 144,313 - 22,693 121,620 4.74 Total investment securities held to maturity $ 156,190 $ - $ 23,431 $ 132,759 4.73 The following tables show the Corporation’s held-to-maturity 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 September 30, 2017 and December 31, 2016 : As of September 30, 2017 Less than 12 months 12 months or more Total Unrealized Unrealized Unrealized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 130,125 $ 20,502 $ 130,125 $ 20,502 As of December 31, 2016 Less than 12 months 12 months or more Total Unrealized Unrealized Unrealized Fair Value Losses Fair Value Losses Fair Value Losses (In thousands) Debt securities: Puerto Rico Municipal Bonds $ - $ - $ 132,759 $ 23,431 $ 132,759 $ 23,431 The Corporation determine s the fair mark et 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. Approximately 70 % of the held-to-maturity municipal bonds were issued by three of the largest m unicipalities 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 rate d by external credit agencies. In most cases, t hese bonds have priority over the payment of operating cost s 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 PROMESA oversight board has not designated any of the Commonwealth’s 78 municipalities as covered entities under PROMESA. However, while the revised fiscal plan submitted by the Puerto Rico governme nt did not contemplate a restructuring of the debt of Puerto Rico’s municipalities, the plan did call for the gradual elimination of budgetary subsidies provided to municipalities. Furthermore, municipalities are also likely to be affected by the negative economic and other effects resulting from the recent storms and 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 e ntities, such as the gradual reduction of the Municipal Contribution in Lieu of Taxes (“CILT”) included in the Puerto Rico Electric Power A uthority (“PREPA”) fiscal plan and t he GDB Restructuring Support Agreement (the “GDB RSA”). The GDB RSA provides for the restructuring under Title VI of PROMESA of substantial portions of the GDB’s indebtedness, including deposits of municipalities , through the issuance of “Participating Bond Claims” i n exchange for the release of GDB from liability relating to the bonds , deposits, letters of credit and guarantees . Given the uncertain impact 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 if future impairment charges will be required relating to these securities. From time to time, the Corporation has securities held to maturity with an original maturity of three months or less that are considered cash and cash equivalents and classified as money market investments in the consolidated statements of f inancial condition. As of September 30, 2017 and December 31, 2016, the Corporation had no outstanding securities held to maturity that were classified as cash and c ash equivalents .

(2) Amount excludes purchased-credit impaired ("PCI") loans with a carrying value of approximately $157.8 million and $165.8 million as of September 30, 2017 and December 31, 2016, 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 non-performing 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. (3) Non-performing loans exclude $388.8 million and $384.9 million of Troubled Debt Restructuring ("TDR") loans that are in compliance with modified terms and in accrual status as of September 30, 2017 and December 31, 2016, respectively. Loans in Process of Foreclosure As of September 30, 2017, the recorded investment of residential mortgage loans collateralized by residential real estate property that are in the process of foreclosure amounted to $ 156.8 million, including $ 24.4 million of loans insured by the FHA or guaranteed by the VA, and $ 20.2 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 o f 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 (Puerto Rico , Florida and USVI ) require the foreclosure to be pro cessed through the state’s court while foreclo sure in non-judicial states (BVI) is processed without court intervention. Foreclosure timelines v ary according to state law and investor g uidelines. Occasionally , foreclosures may be delayed due to mandatory m ediations, bankruptcy , court delays and title issues, among other reasons .

Credit card loans continue to accrue finance charges and fees until charged-off at 180 days. (2) It is the Corporation's policy to report delinquent residential mortgage loans insured by the FHA or guaranteed by the VA as past-due loans 90 days and still accruing as opposed to non-performing loans since the principal repayment is insured. These balances include $29.3 million of residential mortgage loans insured by the FHA or guaranteed by the VA that are over 15 months delinquent, and are no longer accruing interest as of December 31, 2016. (3) As of December 31, 2016, includes $43.7 million of defaulted loans collateralizing GNMA securities for which the Corporation has an unconditional option (but not an obligation) to repurchase the defaulted loans. (4) According to the Corporation's delinquency policy and consistent with the instructions for the preparation of the Consolidated Financial Statements for Bank Holding Companies (FR Y-9C) required by the Federal Reserve Board, residential mortgage, commercial mortgage, and construction loans are considered past due when the borrower is in arrears on two or more monthly payments. FHA/VA government-guaranteed loans, other residential mortgage loans, commercial mortgage loans, land loans and construction-residential loans past due 30-59 days as of December 31, 2016 amounted to $9.9 million, $142.8 million, $4.6 million, $0.7 million and $0.4 million, respectively. In working with borrowers affected by Hurricanes Irma and Maria , which made landfall on September 6, 2017 and September 20, 2017, respectively, the Corporation provided automatic three-month deferred repayment arrangements across-the-board to all consumer borrowers (i.e. personal loans, auto loans, finance leases and credit cards) who wer e current in their payments or no more than 2 payment in arrears as of the date of the respective hurricane. For residential mortgage loans, the Corporation has entered into deferral payment agreements on 10,160 residential mortgages totaling $ 1.3 billion that provide for a three - month payment deferral for those loans current or no more than 2 payment in arrears as of the date of the event. The qualifying mortgage borrowers were required to contact the Corporation and opt in for the program. For both consumer and residential mortgage loans subject to the deferral progr ams, each borrower is require d to resume making their regularly scheduled loan payment s at the end of the deferral period and the deferred amounts were moved to the end of the loan. The payment deferral programs were applied prospectively from the respecti ve dates of the events and did not change the delinquency status of the loans as of such dates. Accordingly, if all payments were current at the date of the event, the loan will not be reported as past due during the deferral period. Furthermore, for loan s subject to the deferral programs on which payments were past due prior to the event , the delinquency status of such loans was frozen to the status that existed at the date of the event until the end of the deferral period. As of September 30, 2017, resid ential mortgage loans in early delinquency (i.e ., 60-89 days in the table above) include $ 86.3 million of loan s subject to the storm-related deferral programs established in Puerto Rico and the Virgin Islands. The Corporation’s credit quality indicators by loan type as of September 30, 2017 and December 31, 2016 are summarized below: Commercial Credit Exposure - Credit Risk Profile Based on Creditworthiness Category: Substandard Doubtful Loss Total Adversely Classified (1) Total Portfolio September 30, 2017 (In thousands) Commercial mortgage $ 158,960 $ 6,416 $ - $ 165,376 $ 1,601,638 Construction: Land 18,753 - - 18,753 29,953 Construction - commercial 35,520 - - 35,520 91,577 Construction - residential 701 - - 701 7,930 Commercial and Industrial 142,800 3,472 798 147,070 2,144,236 Commercial Credit Exposure - Credit Risk Profile Based on Creditworthiness Category: Substandard Doubtful Loss Total Adversely Classified (1) Total Portfolio December 31, 2016 (In thousands) Commercial mortgage $ 193,391 $ 35,416 $ - $ 228,807 $ 1,568,808 Construction: Land 19,345 - - 19,345 31,766 Construction - commercial 36,893 - - 36,893 77,475 Construction - residential 1,933 - - 1,933 15,710 Commercial and Industrial 133,599 67,996 784 202,379 2,180,455 _________ (1) Excludes $8.3 million and $8.1 million of construction-land non-performing loans held for sale as of September 30, 2017 and December 31, 2016, respectively. The Corporation considers a loan as adversely classified if its risk rating is Substandard, Doubtful or Loss. These categories are defined as follows: Substandard- A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified 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 sus tain some loss if the deficiencies are not corrected. Doubtful- Doubtful classifications have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basi s of currently known facts, conditions and values, highly questionable and improba ble. A Doubtful classification may be appropriate in cases where significant risk exposures are perceived, but l oss cannot be determined because of specific reasonable pendin g 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 h as absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. There is little or no prospect for near term improv ement and no realistic strengthening action of significance pending.

The Corporation also acquired PCI loans in previously completed asset acquisitions that are accounted for under ASC 310-30. These previous transactions include the acquisition from Doral Financial in the second quarter of 2014 of all Doral Fi nancial’s rights, title and interest in first and second residential mortgages loans in full satisfaction of secured borrowings owed by such entity to FirstBank . Under ASC 310-30, the acquired PCI loans were aggregated into pools based on similar chara cteristics (i.e . , delinquency status, 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 by the Corporation under ASC 310-30, the y are not considered non-performing 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 portfoli o when it is probable that the Corporation will be unable to collect all cash flows expected as of the acquisition date plus additional cash flows expected to be collected arising from changes in estimates after the acquisition date.

PCI residential mortgage loans and commercial mortgage loans past due 30-59 days as of December 31, 2016 amounted to $22.3 million and $0.1 million, respectively. Initial Fai r Value and Accretable Yield of PCI Loans At acquisition, the Corporation estimated the cash flows the Corporation expected to collect on the PCI 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 statement of financial condition. The exces s 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 metho d. Changes in accretable yield of acquired loans Subsequent to an 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 fr om 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 losses. During the first nine months of 201 7 , the Corporation increas ed by $ 3.4 million to $ 10.2 million the reserve related to PCI loans acquired from Doral Financial in 2014 and from Doral Bank in 2015 . The reserve is driven by the revisions to the expected cash flows of the portfolio s for the remaining term of the loan po ol s based on expected performance and market conditions. Changes in the accretable yield of PCI loans for the quarters and nine-month periods ended September 30, 2017 and 2016 were as follows: Quarter Ended Nine-Month Period Ended September 30, September 30, September 30, September 30, 2017 2016 2017 2016 (In thousands) Balance at beginning of period $ 108,971 $ 122,179 $ 116,462 $ 118,385 Accretion recognized in earnings (2,656) (2,875) (8,177) (8,691) Reclassification (to) from non-accretable - - (1,970) 9,610 Balance at end of period $ 106,315 $ 119,304 $ 106,315 $ 119,304 Changes in the carrying amount of loans accounted for pursuant to ASC 310-30 were as follows: Quarter Ended Nine-Month Period Ended September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 (In thousands) Balance at beginning of period $ 160,368 $ 169,690 $ 165,818 $ 173,913 Accretion 2,656 2,875 8,177 8,691 Collections (4,225) (4,184) (13,327) (13,136) Foreclosures (1,005) (240) (2,874) (1,327) Ending balance $ 157,794 $ 168,141 $ 157,794 $ 168,141 Allowance for loan losses (10,235) (6,857) (10,235) (6,857) Ending balance, net of allowance for loan losses $ 147,559 $ 161,284 $ 147,559 $ 161,284 Changes in the allowance for loan losses related to PCI loans follows: Quarter Ended Nine-Month Period Ended September 30, 2017 September 30, 2016 September 30, 2017 September 30, 2016 (In thousands) Balance at beginning of period $ 9,446 $ 6,857 $ 6,857 $ 3,962 Provision for loan losses 789 - 3,378 2,895 Balance at end of period $ 10,235 $ 6,857 $ 10,235 $ 6,857 The outstanding principal balance of PCI loans, including amounts charged off by the Corporation, amounted to $ 196.4 million as of September 30, 2017 (December 2016 - $ 207.3 million). Purchases and Sales of Loans During the first nine months of 2017, the Corporation purchased $ 48.9 million of residential mortgage loans consistent with a strategic program to purchase ongoing residential mortgage loan production from mortgage bankers in Puerto Rico. Generally, the loans purchased from mortgage bankers were conforming residential mortg age 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. Whe n 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 government-sponsored entities (“GSEs”) such as Fannie Mae (“FNMA”) and Freddie Mac (“FHLMC”), which generally securitize the transferred loans into mortgage-backed securities for sale into the secondary market. The Corporation sold approximately $ 69.5 million of performing residential mortgage loans to FNMA and FHLMC during the first nine months of 2017. Also, during the first nine months of 2017, the Corporation sold $ 200.2 million of FHA/VA mortgage loans to GNMA, which packages them into mortgage-backed securities. The Corporation’s continuing in volvement in these sold loans consists primarily of servicing the loans. In addition, the Corporation agrees to repurchase loans when 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 unilater al 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 statement of financial condition regardless of the Corpora tion’s intent to repurchase the loan. During the first nine months of 2017 and 2016, the Corporation repurchased, pursuant to its repurchase option with GNMA, $ 24.7 million and $ 20.9 million, respectively, of loans previously sold to GNMA. The princip al balance of these loans is fully guaranteed and

As described in Note 2 – “Natural Disasters Affecting First BanCorp. in Third Quarter 2017” two strong hurricanes affected the Corporation’s service areas during September 2017. These storms caused widespread property damage, flooding, power outages, and water and communication services interruptions, and severely disrupted normal economic activity in the affected areas. Damages associated with the storm-related events will have significant short-term economic repercussions, both positive and negative, for the Corporation’ s commercial and individual loan customers in the most severely affected parts of Puerto Rico and the Virgin Islands . While these events have affected certain asset quality metrics, including higher delinquencies and non-performing lo ans, the storms’ ultimate effect on loan collections is uncertain. However, the Corporation’s loan officers are making individual storm-impact assessments for all commercial customers. The recent occurrence of the events makes it difficult to estimate the immediate impact at such level. The expectation is that the assessment will be substantially completed by the fourth quarter of 2017. The Corporation’s loan portfolio in Puerto Rico and the Virgin Islands totaled $ 7.3 billion as of September 30, 2017, or 82 % of the entire portfolio. The composition of these loans generally reflects the composition of the entire portfolio, which is close to 60 % of residential and consumer loans to individual customers and 40 % of commercial and construction loans. Manag ement has determined a separate qualitative element of the allowance to represent the estimate of inherent losses associated with the impact of the storm-related events on the Corporation’s Puerto Rico and Virgin Islands loan portfolios. This estimate is judgmental and subject to changes as conditions evolve. This qualitative element of the allowance was determined based on the estimated impact the storms could have on current employment levels (e.g unemployment rate that doubles current levels in Puerto Rico based on statistics observed in the aftermath of similar natural disasters in the U.S mainland like Hurricane Katrina ) economic activity in the Corporation’s geographic regions, and the time it could take for the affected regions to return to a more normalized operating environment. It is expected that the rebuil ding efforts will stimulate economic activity and accelerate the pace of economic recovery from the hurricanes. The Corporation’s credit risk modeling framework used to determine the storm-related estimate is similar to the one used for benchmarking pur poses as part of the annual Dodd-Frank Act Stress Testing (“DFAST”) regulatory exercise. Models were developed following a regression modeling approach in which relationships between portfolio-level loss rates and key economic indicators were derived base d on historical behavior. These models went through an extensive model specification and selection process that resulted in the use of certain variables, such as the unemployment rate and the Puerto Rico Economic Activity Index, which showed the highest p redictive power of potential losses in our outstanding loan portfolio. Resulting loss factors were assigned to the overall performing balance of each major loan portfolio category in the affected regions, resulting in a total charge of $ 66.5 million (com posed of $ 59.2 million for Puerto Rico and $ 7.3 million for Virgin Islands) that consisted of: (i) a $ 13.7 million charge to the provision for residential mortgage loans, (ii) an $ 18.1 million charge to the provision of commercial mortgage loans, (iii) an $ 8.0 million charge to the provision for commercial and industrial loans, (iv) a $ 0.8 million charge to the provision for construction loans, and (v) a $ 25.9 million charge to the provision for consumer loans. Residential and consumer loans are underwr itten principally on income streams, with collateral viewed as a second source of repayment. The storms’ impact varies widely within the residential and consumer portfolio, with some individual borrowers experiencing the devastation of loss of both home a nd employment and others with both homes and jobs intact. Properties used as collateral generally require insurance, minimizing the potential loss from property damages. For the commercial portfolio, the Corporation conducted a preliminary review of al l loans in the Puerto Rico and Virgin Islands regions in amounts over $ 10 million, which accounts for 74.5 % of the total commercial portfolio of such regions, and determined that 100 % of the real estate-backed loans have property insurance. As such, the Co rporation understands that credit losses and/or credit deterioration will mainly occur from the overall economic effect the storms will have on the economy of Puerto Rico and the Virgin Islands. Estimates of the storms’ effect on loan losses will change o ver time as additional information becomes available, and any related revisions in the allowance calculation will be reflected in the provision for loan losses as they occur. Such revisions could be material. As of September 30, 2017 , the Corporation maintained a $ 0.9 million reserve for unfunded loan commitments (December 31, 2016 - $ 1.6 million), mainly related to outstanding commitments on floor plan revolving lines of credit. The reserve for unfunded loan commitments is an estimate of the losses in herent 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 am ounts for unfunded commitments. The reserve for unfunded loan commitments is included as part of accounts payable and other liabilities in the consolidated statement of financial condition and any change to the reserve is included as part of other non-inte rest expenses in the consolidated statements of income.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	9 Months Ended

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	NOTE 11 – 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 chan ges 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 September 30, 2017 and December 31, 2016 , all derivatives h eld 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 increases as the reference interest rate rises. The Corporation enters into interest rate cap agreements for protection from rising interest rates. Forward Contracts - F orward contracts are sales of to-be-announced (“TBA”) mortgage-backed securities that will settle over the standard delivery d ate 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 f orward sales are considered derivative instruments that need to be marked to market. These securities are used to economically hedge the FHA/VA residential mortgage loan securitizations of the mortgage-banking operations . Unrealized gains (losses) are recognized as part of mortgage banking activities in the consolidated statements of income. To satisfy the needs of i ts customers, the Corporation may enter into non - hedging trans actions. On these transactions, the Corporation generally participates as a buyer in one of the agreeme nts and as a seller in the other agreement under the same terms and conditions. In additio n, the Corporation enter s 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 economi c 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. The following table summarizes the notional amounts of all derivative instruments: Notional Amounts (1) As of As of September 30, December 31, 2017 2016 (In thousands) Undesignated economic hedges: Interest rate contracts: Written interest rate cap agreements $ 91,510 $ 91,510 Purchased interest rate cap agreements 91,510 91,510 Forward Contracts: Sale of TBA GNMA MBS pools 20,000 33,000 $ 203,020 $ 216,020 (1) Notional amounts are presented on a gross basis with no netting of offsetting exposure positions.

As is the case with investment securities, the market value of derivative instruments is largely a function of the financial market’s expectations regarding the future direction of interest rates. Accordingly, current market values are not necessarily indicative of the future impact of derivative instruments on earnings. This will depend, for the most part, on the shape of the yield curve and the level of interest rates, as well as the expectations for rates in the future. As of September 30, 2017, the Corporation has not entered into any derivative instrument containing credit-risk-related contingent features.

GOODWILL AND OTHER INTANGIBLES	NOTE 13 – GOODWILL AND OTHER INTANGIBLES Goodwill as of September 30, 2017 and December 31, 201 6 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 intangibles during the fourth quarter of 2016. The Corporation’s goodwill is related to the acquisition of FirstBank Florida in 2005. There have been no significant events related to the Florida reporting unit that coul d indicate potential goodwill impairment since the date of the last evaluation; therefore, no goodwill impairment evaluation was performed during the first nine months of 2017. Goodwill and other indefinite life intangibles are reviewed at least annually f or 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, which is being amortized ov er the remaining estimated life of 4.2 years on an accelerated basis based on the estimated attrition rate of the purchased credit card accounts, which reflects the pattern in which the economic benefits of the intangible asset are consumed. These benefits are consumed as the revenue stream generated by the cardholder relationship is realized. The core deposit intangible acquired in the February 2015 Doral Bank transaction amounted to $ 5.8 million ($ 3.9 million as of September 30, 2017). In the fi rst 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 ($0.8 million as of September 30, 2017) , which is being a mortized over the next 5.3 years on a straight-line basis. The acquired accounts ha ve 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 September 30, December 31, 2017 2016 (Dollars in thousands) Core deposit intangible: Gross amount, beginning of period $ 51,664 $ 51,664 Accumulated amortization (1) (45,779) (44,466) Net carrying amount $ 5,885 $ 7,198 Remaining amortization period 7.3 years 8.1 years Purchased credit card relationship intangible: Gross amount $ 24,465 $ 24,465 Accumulated amortization (2) (15,832) (13,934) Net carrying amount $ 8,633 $ 10,531 Remaining amortization period 4.2 years 5 years Insurance customer relationship intangible: Gross amount $ 1,067 $ 1,067 Accumulated amortization (3) (254) (140) Net carrying amount $ 813 $ 927 Remaining amortization period 5.3 years 6.1 years (1) For the quarter and nine-month period ended September 30, 2017, the amortization expense of core deposit intangibles amounted to $0.4 million and $1.3 million, respectively (2016 - $0.5 million and $1.5 million, respectively). (2) For the quarter and nine-month period ended September 30, 2017, the amortization expense of the purchased credit card relationship intangible amounted to $0.6 million and $1.9 million, respectively (2016 - $0.7 million and $2.1 million, respectively). (3) For the quarter and nine-month period ended September 30, 2017, the amortization expense of insurance customer relationship intangible amounted to $38 thousand and $0.1 million, respectively (2016 - $38 thousand and $0.1 million, respectively). The estimated aggregate annual amortization expense related to these intangible assets for future periods is as follows: Amount (In thousands) 2017 $ 1,077 2018 3,591 2019 3,088 2020 2,851 2021 2,658 2022 and after 2,066

NON-CONSOLIDATED VARIABLE INTER

NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	9 Months Ended

NON-CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS	NOTE 14 – NON CONSOLIDATED VARIABLE INTEREST ENTITIES AND SERVICING ASSETS The Corporation transfers residential mortgage loans in sale or securitization transactions in which it has continuing involveme nt, 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 Cor poration 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 i s the primary beneficiary of the VIE and whether the entity should be consolidated or not. Below is a summary of transfers of financial assets to VIEs for which the Corporation has retained some level of continuing involvement: GNMA The Corporation typi cally 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 throu gh these transactions are guaranteed by the issuer and, as such, under seller/servicer agreements, the Corporation is required to service the loans in accordance with the issuers’ servicing guidelines and standards. As of September 30, 2017 , the Corpor ation serviced loans securitized through GNMA with a principal balance of $ 1.6 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 millio n of its variable rate trust-preferred securities. 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, were used by FBP Statutory Trust I to p urchase $ 103.1 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. Also in 2004, FBP Statutory Trust II, a financing trust that is wholly owned by the Corporation, sold to institutional investors $ 125 million of its variable rate trust-preferred securities. 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, were used by FBP Statutory Trust II to p urchase $ 128.9 million aggregate principal amount of the Corporation’s Junior Subordinated Deferrable Debentures. The debentures are presented in the Corporation’s consolidated statements of financial condition as Other Borrowings, net of related issuance costs. The variable rate trust-preferred securities are fully and unconditionally guaranteed by the Corporation. The Junior Subordinated Deferrable Debentures issued by the Corporation in April 2004 and in September 2004 mature on June 17, 2034 and Septemb er 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 trust-preferred securities). During the third quarter of 2017, the Corporation completed the repurchase of $ 7.3 million of trust preferred securities of the FBP Statutory Trust I that were offered to the Corporation by an investment banking firm. The Corporation repurchased and cancelled the repurchased trust preferred securities, resulting in a commensurate reduction in the related Floating Rate Junior Subordinated Debenture. The Corporation’s purchase price equated to 81 % of the $7.3 million par value. The 19 % discount, plus accrued interest, resulted in a gain of approximately $1.4 million, which is reflected in the statement of income as a “Gain on early extinguishment of debt”. In a separate transaction, d uring the first quarter of 2016, the Corporation completed the repurchase of $ 10 million of trust-preferred securities of the FBP Statutory Trust II that were auctioned in a public sale at which the Corpora tion was invited to p articipate. The Corporation repurchased and cancelled the repurchased trust preferred securities, resulting in a commensurate reduction in the related Junior Subordinated Deferrable Debentures. The Corporation’s winning bids equated to 70 % of the $10 milli on par value. The 30 % discount, plus accrued interest, resulted in a gain of approximately $4.2 million, which is also reflected in the statement of income as a “Gain on early extinguishment of debt.” During the second quarter of 2015, the Corporation issu ed 852,831 shares of the Corporation’s common stock in exchange for $ 5.3 million of trust preferred securities (FBP Statutory Trust I), which enabled the Corporation to cancel $ 5.5 million of the carrying value of the debentures underlying the purchased tr ust preferred securities. The Collins Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act eliminates certain trust-preferred securities from Tier 1 Capital; however, these instruments may remain in Tier 2 capital until the ins truments 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 payme nt 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 received approval from the Federal Reserve and paid $ 31.2 million for all the accrued but deferred interest payments plus the interest for the second quarter on the Corporation’s subordinated debentures associated with its trust preferred securities. Subsequently, the Corporation received quarterly approvals and made sch eduled quarterly interest payments for the third and fourth quarters of 2016 and the first, second and third quarters of 2017. The Corporation received approval to make the quarterly payment for December 31, 2017. As of September 30, 2017, the Corporation is current on all interest payments due on its subordinated debt. On October 2017, the Federal Reserve Bank of New York terminated the formal written agreement (the “Written Agreement”) entered into on June 3, 2010 between the Corporation and the Reserve Bank. However, the Corporation has agreed with the Reserve Bank to continue to obtain the approval of the Reserve Bank before paying dividends, receiving dividends from the Bank, making payments on subordinated debt or trust preferred securitie s, incurring or guaranteeing debt or purchasing or redeeming any corporate stock. Grantor Trusts During 2004 and 2005, a third party to the Corporation, 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 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 whic h 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 ca sh flows is performed by another third party, which receives a servicing fee. The securities 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 servi cing 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 r ecourse agreement exists and the risks from losses on non-accruing loans and repossessed collateral are absorbed by the Bank as the sole holder of the certificates. As of September 30, 2017 , the amortized cost and fair value of the Grantor Trusts amounted to $ 23.6 million and $ 17.6 million, respectively, with a weighted average yield of 2.38 %. Investment in unconsolidated entity On February 16, 2011, FirstBank sold an asset portfolio consisting of performing and non-performing 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, Sa chs & 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 ha s a seven-year maturity and bears variable interest at 30-day LIBOR plus 300 basis points and is secured by a pledge of all of the acquirin g entity's assets as well as PRLP’s 65 % ownership interest in CPG/GS. As of September 30, 2017 , the carrying amount of the loan was $ 4.0 million, which was included in the Corporation's c ommercial and i ndustrial loans held for investment portfolio. FirstBank’s equity interest in CPG/GS is accounted for under the equity method . When applying the equity method, the Bank follows the Hypothetical Liquidation Book Value method (“HLBV”) to determine its share of CPG/GS’s earnings or loss. The loss recorded in 2014 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. Any potential increase in the carrying value of the investment in CPG/ GS, under the HLBV method, would depend upon how better off the Bank is at the end of the period than it was at the beginning of the period after the waterfall calculation performed to determine the amount of gain allocated to the investors. FirstBank also provided an $ 80 million advance facility to CPG/GS to fund unfunded commitments and costs to complete projects under construction, which was fully disbursed in 2011, and a $ 20 million working capital line of credit to fund certain expenses of CPG/GS. T he working capital line expired in September 2016 and no amount is outstanding. During 2012, CPG/GS repaid the outstanding balance of the advance facility to fund unfunded commitments, and the funds became available for rewithdrawal under a one-time revo lver agreement. This facility loan bears variable interest at 30-day LIBOR plus 300 basis points. As of September 30, 2017 , the carrying value of the revolver agreement was $ 6.7 million, which was included in the Corporation's commercial and industrial loans held for investment portfolio. Ca sh proceeds received by CPG/GS have been first used to cover operating expenses and debt service payments, including those related to the note receivable and the advance facility described above, which must be s ubstantially 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 i nvestment and a priority return of at least 12 %, 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 achiev ed 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 determinin g 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 activi ties of CPG/GS that most significantly impact the entity's economic performance and the obligation to absorb losses of CPG/GS that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be signif icant 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 the loan portfolio, impact foreclosure proceedings, or manage the construction and sale of the property; therefore, the Bank concluded that it is not the primary beneficiary of CPG/GS. As a creditor to CPG/GS, the Bank has certain rights related to CPG/GS; however, these are intended to be protective in nature and do not provide the Bank with the ability to manage the operations of CPG/GS. Since CPG/GS is not a consolidated subsidiary of the Bank and the transaction met the criteria for sale accounting under authoritative guidance, the Bank accounted for this transaction as a true sale, recognizing the cash received, the notes receivable, and the intere st in CPG/GS, and derecognizing the loan portfolio sold. Servicing Assets The Corporation sells residential mortgage loans to GNMA, which generally securitizes the transferred loans into mortgage-backed securities. Also, certain conventional conforming loans are sold to FNMA or FHLMC with servicing retained. The Corporation recognizes as separate assets the rights to service loans for others, whether those servicing assets are originated or purchased. The changes in servicing assets are shown below: Quarter Ended Nine-Month Period Ended September 30, September 30, (In thousands) 2017 2016 2017 2016 Balance at beginning of period $ 26,502 $ 25,044 $ 26,244 $ 24,282 Capitalization of servicing assets 833 1,420 2,757 3,878 Amortization (775) (817) (2,342) (2,424) Adjustment to fair value (690) (263) (1,047) (387) Other (1) 129 91 387 126 Balance at end of period $ 25,999 $ 25,475 $ 25,999 $ 25,475 (1) Amount represents the adjustment to fair value 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 Nine-Month Period Ended September 30, September 30, 2017 2016 2017 2016 (In thousands) Balance at beginning of period $ 197 $ 260 $ 461 $ 136 Temporary impairment charges 690 266 1,047 460 OTTI of servicing assets - - (621) - Recoveries - (3) - (73) Balance at end of period $ 887 $ 523 $ 887 $ 523 The components of net servicing income are shown below: Quarter Ended Nine-Month Period Ended September 30, September 30, 2017 2016 2017 2016 (In thousands) Servicing fees $ 1,898 $ 1,930 $ 5,897 $ 5,657 Late charges and prepayment penalties 103 200 340 505 Adjustment for loans repurchased 129 91 387 126 Other (1) - - (35) (1) Servicing income, gross 2,130 2,221 6,589 6,287 Amortization and impairment of servicing assets (1,464) (1,080) (3,389) (2,811) Servicing income, net $ 666 $ 1,141 $ 3,200 $ 3,476 (1) Mainly consisted of compensatory fees imposed by GSEs. 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 Nine-Month Period Ended September 30, 2017: Constant prepayment rate: Government-guaranteed mortgage loans 6.2 % 6.0 % Conventional conforming mortgage loans 6.7 % 6.3 % Conventional non-conforming mortgage loans 9.5 % 9.1 % Discount rate: Government-guaranteed mortgage loans 12.0 % 12.0 % Conventional conforming mortgage loans 10.0 % 10.0 % Conventional non-conforming mortgage loans 14.3 % 14.3 % Nine-Month Period Ended September 30, 2016: Constant prepayment rate: Government-guaranteed mortgage loans 7.6 % 6.1 % Conventional conforming mortgage loans 8.0 % 6.5 % Conventional non-conforming mortgage loans 14.1 % 10.6 % Discount rate: Government-guaranteed mortgage loans 12.0 % 11.5 % Conventional conforming mortgage loans 10.0 % 9.5 % Conventional non-conforming mortgage loans 14.3 % 13.8 % The weighted-averages of the key economic assumptions used by the Corporation in its valuation model and the sensitivity of the current fair value to immediate 10 % and 20 % adverse changes in those as sumptions for mortgage loans as of September 30, 2017 were as follows: (Dollars in thousands) Carrying amount of servicing assets $ 25,999 Fair value $ 29,543 Weighted-average expected life (in years) 8.30 Constant prepayment rate (weighted-average annual rate) 6.41% Decrease in fair value due to 10% adverse change $ 767 Decrease in fair value due to 20% adverse change $ 1,500 Discount rate (weighted-average annual rate) 11.22% Decrease in fair value due to 10% adverse change $ 1,383 Decrease in fair value due to 20% adverse change $ 2,653 These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship between the change in assumption and the change in fair value may not be linear. Also, in this table, the effect of a variation in a particular assumption on the fair value of the servicing asset is calculated without changing any other assumption; in reality, changes in one factor may resul t in changes in another (for example, increases in market interest rates may result in lower prepayments), which may magnify or counteract the sensitivities.

IMPAIRMENT ON FIXED ASSETS

Text Block [Abstract]
Asset Impairment Charges [Text Block]	NOTE 15 – IMPAIRMENT OF FIXED ASSETS The Corporation identified impairment to several of its facilities and equipment in the areas affected by Hurricanes Irma and Maria. Losses related to the damaged facilities and equipment have been charged against earnings in the third quarter of 2017, and included as a component of “Other non-interest income” in the statement of (loss) income . The losses have been determined with information currently available as to carrying amounts of impaired assets and extent of damage sustained. Management has currently identified asset impairments of approximately $ 0.6 million as of September 30, 2017. If the sustained damage differs from the initial assessments, the result could cause additional charges for estimated losses through the end of 2017. The Corporation maintains insurance policies for casualty losses that provide for replacement value coverage. Management believes, based on its understanding of the insurance coverages, that recovery o f asset impairments identified as of September 30, 2017 is probable. As such, insurance recoveries of $ 0.6 million was recorded in the third quarter of 2017, also as a component of “Other non-interest income” in the statement of (loss) income, and the corr esponding receivable was included as part of “Other assets” in the statement of financial condition as of September 30, 2017.

STOCKHOLDERS' EQUITY	NOTE 20 – STOCKHOLDERS’ EQUITY Common Stock As of September 30, 2017 and December 31, 2016 , the Corporation had 2,000,000,000 authorized shares of common stock with a par value of $0.10 per share. As of September 30, 2017 and December 31, 2016 , there were 220,220,026 and 218,700,394 shares issued, respectively, and 216,175,003 and 217,446,205 shares outstanding, respectively. Refer to Note 4 for information about transactions related to common stock under the Omnib us Plan. On May 10, 2017, the U.S. Department of the Treasury announced that it sold all of its remaining 10,291,553 shares of the Corporation’s common stock. Since the U.S. Treasury did not recover the full amount of its original investment under TARP , 2,370,571 outstanding restricted shares held by the Corporation’s employees were forfeited, resulting in a reduction in the number of common shares outstanding. On February 7, 2017, a secondary offering of the Corporation’s common stock by certain o f the Corporation’s existing stockholders was completed. Funds affiliated with Thomas H. Lee Partners, L.P. (“THL”) sold 10 million shares of the Corporation’s common stock, and funds managed by Oaktree Capital Management, L.P. (“Oaktree”) sold 10 million shares of the Corporation’s common stock. Subsequently, the underwriters exercised their option to purchase an additional 3 million shares of the Corporation’s common stock from the selling stockholders. O n August 3 , 2017, THL and Oaktree participated in another secondary offering of the Corporation’s common stock in which they sold an aggregate of 20 million shares ( 10 million shares each) of common stock. The Corporation did not receive any proceeds from these offering . As of September 30, 2017, each of THL and Oaktree owned less than 5 % of the Corporation’s 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 ma y be issued in series and the shares of each series will have such rights and preferences as are fixed by the Board of Directors when authorizing the issuance of that particular series. As of September 30, 2017 , the Corporation has five outstanding ser ies 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 preferr ed 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, afte r receiving regulatory approval. Since then, the Corporation has continued to paid monthly dividend payments on the non-cumulative perpetual monthly income preferred stock. The Corporation has received regulatory approval to pay the monthly dividends on th e Corporation’s Series A through E Preferred Stock through December 2017. On October 3, 2017, the Federal Reserve terminated the Written Agreement entered to on June 3, 2010 between the Corporation and the Federal Reserve. However, the Corporation ha s agreed with the Federal Reserve to continue to obtain its approval before paying dividends, receiving dividends from the Bank, making payments on subordinated debt or trust preferred securities, incurring or guaranteeing debt or purchasing or redeeming a ny corporate stock. Treasury stock During the first nine months of 2017 and 2016 , the Corporation withheld an aggregate of 386,611 shares and 255,102 shares, respectively, of the common stock paid to certain senior officers as additional compensation and rest ricted stock that vested during the first nine months of 2017 and 2016 to cover employees’ payroll and income tax withholding liabilities; these shares are held as treasury shares. In addition, 2,404,223 shares of restricted stock forfeited in the first nine months of 2017 are now held as treasury shares. As of September 3 0 , 201 7 and December 31, 201 6 , the Corporation had 4,045,023 and 1,254,189 shares held as treasury stock, respectively. FirstBank Statutory Reserve (Legal Surplus) The Banking Law of the Commonwea lth of Puerto Rico requires that a minimum of 10 % of FirstBank’s net income for the year be transferred to legal surplus until such surplus equals the total of paid-in-capital on common and preferred stock. Amounts transferred to the legal surplus account from the retained earnings account are not available for distribution to the Corporation, including for payment as dividends to the stockholders, without the prior consent of the Puerto Rico Commissioner of Financial Institutions. The Puerto Rico Banking L aw 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 reserve fund, as a reduction thereof. If there is no reserve fund 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 res erve fund to an amount of at least 20 % of the original capital contributed. During the fourth quarter of 201 6 , $ 9 . 6 million was transferred to the legal surplus reserve. FirstBank’s legal surplus reserve, included as part of retained earnings in the Corporation’s statement of financial condition, amounted to $ 52.4 million as of September 30, 201 7 . There were no transfer s to the legal surplus reserve during the first nine months of 2017.

INCOME TAXES

INCOME TAXES	9 Months Ended
	Sep. 30, 2017
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 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 con duct of a trade or business in those regions. Any such tax paid in the U.S. and USVI is also either creditable against the Corporation’s Puerto Rico tax liability or taken as a deduction against taxable income, subject to certain conditions and limitations . Under the Puerto Rico Internal Revenue Code of 2011, as amended (the “2011 PR Code”), the Corporation and its subsidiaries are treated as separate taxable entities and are not entitled to file consolidated tax returns and, thus, the Corporation is generally not entitled to utilize losses from one subsidiary to offset gains in another subsidiary. Accordingly, in order to obtain a tax benefit from a net operating loss (“NOL”), a particular subsidiary must be able to demonstrate sufficient taxable inc ome within the applicable NOL carry- forward period. The 2011 PR Code allows entities organized as limited liability companies to perform an election to become a non-taxable “pass-through” entity and utilize losses to offset income from other “pass-through” entities, subject to certain limitations, with the remaining net income passing-through to its partner entities. T he 2011 PR Code also provides a dividend received deduction of 100 % on dividends received from “controlled” subsidiaries subject to taxation in Puerto Rico and 85 % on dividends received from other taxable domestic corporations. On March 1, 2017, the Corporation completed the applicable regulatory filings to change the tax status of its subsidiary, First Federal Finance, from a taxable corpo ration to a non-taxable “pass-through” entity. This election allows the Corporation to realize tax benefits of its deferred tax assets associated with pass-through ordinary net operating losses available at the banking subsidiary, FirstBank, which were sub ject to a full valuation allowance as of December 31, 2016, against now pass-through ordinary income from this profitable subsidiary. On March 1, 2017, the Corporation also completed the applicable regulatory filings to change the tax status of its subsid iary, FirstBank Insurance, from a taxable corporation to a non-taxable “pass-through” entity. This election allows the Corporation to offset pass-through income projected to be earned by FirstBank Insurance with the projected net operating losses at the ho lding company (the “Holding Company”) level. The Corporation has maintained an effective tax rate lower than the maximum statutory rate mainly by investing in government obligations and mortgage-backed securities exempt from U.S. and Puerto Rico incom e 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 a nd 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 third quarter and first nine months of 2017, the Corporation recorded income tax benefits of $8.4 million and $7.2 million, respectively, compared to income tax expense of $10.4 million and $23.7 million, for comparable periods in 2016. The tax benefit for the third quarter of 2017, as compared to the ta x expense for the same period in 2016, was primarily driven by the tax benefit recognized associated with the storm-related loss recorded in the third quarter of 2017 and a lower effective tax rate driven by an increase in the projected ratio of exempt to taxable income . The tax benefit for the first nine months of 2017, as compared to the tax expense for the same period in 2016, was mostly attributable to the tax benefit recognized related to the storm-related charges and the $ 13.2 million tax ben efit recorded in the first quarter of 2017 as a result of the above discussed change in tax status of certain subsidiaries from taxable corporations to limited liability companies that have elected to be treated as partnerships for income tax purposes in P uerto Rico. The $13.2 million tax benefit was primarily associated with the reversal of the $ 13.9 million deferred tax asset valuation allowance previously recorded at FirstBank related to pass-through ordinary net operating losses, partially offset by the elimination of the $ 0.7 million deferred tax asset previously recorded at FirstBank Insurance. A lower effective tax rate for the first nine months of 2017, as compared to the same period in 2016, also contributed to the positive variance in income tax ex pense. For the nine-month period ended September 30, 2017, 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 consol idated worldwide annual estimated effective tax rate, ASC 740-270 requires the exclusion of legal entities with pre-tax losses from which a tax benefit cannot be recognized. The Corporation’s estimated annual effective tax rate in the first nine months of 2017, excluding entities from which a tax benefit cannot be recognized and discrete items, was 20 % compared to 24 % for the first nine months of 2016. The estimated annual effective tax rate including all entities for 2017 was -2 % ( 21 % excluding discrete items, primarily the tax benefit resulting from the previously mentioned change in the tax status of two subsidiaries) compared to 25 % for the first nine months of 2016. The Corporation’s net deferred tax asset amounted to $ 299.8 million as of Septe mber 30, 2017, net of a valuation allowance of $ 186.9 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 th e applicable NOL carry-forward periods to realize such amount. The net deferred tax asset of the Corporation’s banking subsidiary, FirstBank, amounted to $ 299.5 million as of September 30, 2017, net of a valuation allowance of $ 146.6 million, compared to a net deferred tax asset of $ 277.4 million, net of a valuation allowance of $ 171.0 million, as of December 31, 2016. We have U.S. and USVI sourced NOLs that we incurred in prior years. 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 at such jurisdictions following an event resulting in an ownership change. Generally, an ownership change occurs when certain shareholders increase their aggregate ownership by more than 50 percentage points over their lowest ownership percentage over a three-year testing period. Upon the occurrence of a Section 382 ownership change, the use of NOLs attributable to the period prior to the ownership change is subject to limitations and only a portion of the U.S. and USVI NOLs may be used by the Corporation to offset its annual U.S. and USVI taxable income, if any. During the third quarter of 2017, the Corporation completed a formal ownership change analysis within the meaning of Secti on 382 covering a comprehensive period, and concluded that an ownership change occurred during such comprehensive period. The ownership change and resulting Section 382 limitation did not cause a U.S. or USVI income tax liability or material income tax exp ense related to prior periods since the Corporation had sufficient post ownership change NOLs in those jurisdictions to offset taxable income. The Section 382 limitation could result in higher U.S. and USVI liabilities in the future than we would incur in the absence of such limitation. Prospectively, the Corporation expects that it will be able to mitigate the adverse effects associated with the Section 382 limitation as any such tax paid in the U.S. or USVI could be creditable against Puerto Rico tax lia bilities or taken as 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 depends on various factors. For the thir d quarter of 2017, as a result of the Section 382 limitation and based on the tax profile as of September 30, 2017, the Corporation incurred an income tax expense of approximately $ 1.6 million related to its U.S. operations. The limitation did not affect the USVI operations for the third quarter of 2017. As of September 30, 2017, the Corporation did not have Unrecognized Tax Benefits (“UTBs”) recorded on its books. Audit periods remain open for review until the statute of limitations has passed. The s tatute of limitations under the 2011 PR code is four years; the statute of limitations for U.S. Virgin Islands and U.S. income taxes 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 pe riod based, in part, upon the results of operations for the given period. On January 23, 2017, the Corporation received confirmation from the IRS that the audit for the years 2011 and 2012 were closed with no adjustments to the previously filed returns. Fo r Virgin Islands and U.S. income tax purposes, all tax years subsequent to 2012 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2012 remain open to examination.

FAIR VALUE

FAIR VALUE	9 Months Ended
	Sep. 30, 2017
FAIR VALUE	NOTE 22 – 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) mortgage-backed securities 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. For the first nine months of 2017 , there were no transfers into or out of Level 1, Level 2 or Level 3 of the fair value hierarchy. Financial Instruments Recorded at Fair Value on a Recurring Basis Investment securities available for sale The fair value of investment securities available for sale was the market value based on quoted market prices (as is the case with equity securities, Treasury notes, and non-callable U.S. Agency debt securities), when available (Level 1), or, when available, m arket 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, offer s 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 un observable inputs due to the limited market activity of the instrument, as is the case with certain private label mortgage-backed securities held by the Corporation (Level 3). Private label MBS are collateralized by fixed-rate mortgages on single-family residential properties in the United States; the interest rate on the securities is variable, tied to 3-month LIBOR and limited to the weighted-average coupon of the underlying collateral. The market valuation represents the estimated net cash flows over t he projected life of the pool of underlying assets applying a discount rate that reflects market observed floating spreads over LIBOR, with a widening spread based on a nonrated security. The market valuation is derived from a model that utilizes relevant assumptions such as the prepayment rate, default rate, and loss severity on a loan level basis. The Corporation modeled the cash flow from the fixed-rate mortgage collateral using a static cash flow analysis according to collateral attributes of the underl ying mortgage pool (i.e., loan term, current balance, note rate, rate adjustment type, rate adjustment frequency, rate caps, and others) in combination with prepayment forecasts based on historical portfolio performance. The variable cash flow of the secur ity is modeled using the 3-month LIBOR forward curve. Loss assumptions were driven by the combination of default and loss severity estimates, using an asset-level risk assessment method taking into account loan credit characteristics (loan-to-value, state jurisdiction, delinquency, property type and pricing behavior, and other) to provide an estimate of default and loss severity. Refer to the table below for further information regarding qualitative information for all assets and liabilities measured at f air value using significant unobservable inputs (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 rate caps, only the seller's credit r isk is considered. The caps were valued using a discounted cash flow approach and using 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-marke t effect of credit risk in the valuation of derivative instruments for the quarter s and nine-month periods ended September 30, 2017 and 2016 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 possi ble 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 residentia l mortgage loans that collateral ize these obligations that are guaranteed by the Puerto Rico Housing Finance Authority (“PRHFA”). A significant increase (decrease) in the assumed rate would lead to a higher (lower) fair value estimate. The fair value of th ese 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 constrain t s on the bonds considering the absence of an active market for them . Due to the guarantee o f the PRHFA and other applicable contractual safeguards , no additional credit spread is applied for servicer default. The tables below summarize changes in unrealized gains and losses recorded in earnings for the quarters and nine-month periods ended September 30, 2017 and 2016 for Level 3 assets and liabilities that are still held at the end of each period: Changes in Unrealized Losses Changes in Unrealized Losses (Quarter ended September 30, 2017) (Quarter ended September 30, 2016) Level 3 Instruments Only Securities Securities (In thousands) Available For Sale Available For Sale Changes in unrealized losses relating to assets still held at reporting date: Net impairment losses on available-for-sale investment securities (credit component) $ - $ - Changes in Unrealized Losses Changes in Unrealized Losses (Nine-Month Period Ended September 30, 2017) (Nine-Month Period Ended September 30, 2016) Level 3 Instruments Only Securities Securities (In thousands) Available For Sale Available For Sale Changes in unrealized losses relating to assets still held at reporting date: Net impairment losses on available-for-sale investment securities (credit component) $ - $ (387) Additionally, fair value is used on a nonrecurring basis to evaluate certain assets in accordance with GAAP. Adjustments to fair value usually result from the application of lower-of-cost or market accounting (e.g., loans held for sale carried at the lower-of-cost or fair value and repossessed assets) or write downs of individual assets (e.g., goodwill, loans ). As of September 30, 2017, impairment or valuation adjustments were recorded for assets recognized at fair value on a non-recurring basis as shown in the following table: Carrying value as of September 30, 2017 (Losses) recorded for the Quarter Ended September 30, 2017 (Losses) recorded for the Nine-Month Period Ended September 30, 2017 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 374,740 $ (686) $ (23,467) OREO (2) - - 152,977 (818) (7,563) Mortgage servicing rights (3) - - 25,999 (690) (1,047) (1) Consist mainly of impaired commercial and construction loans. The impairments were generally measured based on the fair value of underlying the collateral. The fair values were derived from external appraisals that take into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the collateral (e.g., absorption rates), which are not market observable. (2) The fair values were derived from appraisals that take into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the properties (e.g., absorption rates and net operating income of income producing properties), which are not market observable. Losses were related to market valuation adjustments after the transfer of the loans to the OREO portfolio. (3) Fair value adjustments to mortgage servicing rights were mainly due to assumptions associated with mortgage prepayment rates. The Corporation carries its mortgage servicing rights at the lower of cost or market, measured at fair value on a non-recurring basis. Assumptions for the value of mortgage servicing rights include: Prepayment rate of 6.41%, Discount Rate of 11.22%. As of September 30, 2016, impairment or valuation adjustments were recorded for assets recognized at fair value on a non-recurring basis as shown in the following table: Carrying value as of September 30, 2016 (Losses) recorded for the Quarter Ended September 30, 2016 (Losses) recorded for the Nine-Month Period Ended September 30, 2016 Level 1 Level 2 Level 3 (In thousands) Loans receivable (1) $ - $ - $ 426,444 $ (13,912) $ (41,621) OREO (2) - - 139,446 (1,702) (6,580) Mortgage servicing rights (3) - - 25,475 (263) (387) (1) Consist mainly of impaired commercial and construction loans. The impairments were generally measured based on the fair value of the underlying collateral. The fair value was derived from external appraisals that take into consideration prices in observed transactions involving similar assets in similar locations but adjusted for specific characteristics and assumptions of the collateral (e.g., absorption rates), which are not market observable.

(3) Fair value adjustments to the mortgage servicing rights were mainly due to assumptions associated with mortgage prepayments rates. The Corporation carries its mortgage servicing rights at the lower of cost or market, measured at fair value on a non-recurring basis. Assumptions for the value of mortgage servicing rights include: Prepayment Rate of 6.34%, Discount Rate of 11.18%. Qualitative information regarding the fair value measurements for Level 3 financial instruments are as follows: September 30, 2017 Method Inputs Loans Income, Market, Comparable Sales, Discounted Cash Flows External appraised values; probability weighting of broker price opinions; management assumptions regarding market trends or other relevant factors OREO Income, Market, Comparable Sales, Discounted Cash Flows External appraised values; probability weighting of broker price opinions; management assumptions regarding market trends or other relevant factors Mortgage servicing rights Discounted Cash Flow Weighted average prepayment rate of 6.41%; weighted average discount rate of 11.22% The following is a description of the valuation methodologies used for instruments that are not measured or reported at fair value on a recurring basis or reported at fair value on a non-recurring basis. The estimated fair value was calculated using certain facts and assumptions, which vary depending on the specific financial instrument. Cash and due from banks and money market investments The carrying amounts of cash and due from banks and money market investments are reasonable estimates of their fair value. Money market investments include held-to-maturity securities, which have a contractual maturity of three months or less. The fair value of these securities is based on quoted market prices in active markets that incorporate the risk of nonperf ormance. Investment securities held to maturity Investment securities held to maturity consist of financing arrangements with Puerto Rico municipalities issued in bond form, but underwritten as loans with features that are typically found in commerci al loan transactions. These obligations typically are not issued in bearer form, nor are they registered with the SEC and are not rated by external credit agencies. The fair value of these financing arrangements was based on a discounted cash flow analysis using risk-adjusted discount rates (Level 3). The credit spreads for valuations are based on a similar security that traded in the open market. Other equity securities Equity or other securities that do not have a readily available fair value are stated at their net realizable value, which management believes is a reasonable proxy for their fair value. This category is principally composed of stock that is owned by the Corporation to comply with FHLB regulatory requirements. The realizable value of the F HLB stock equals its cost as this stock can be freely redeemed at par. Loans receivable, including loans held for sale The fair value s of loans held for investment and of mortgage loans held for sale w ere estimated using discounted cash flow analyses, based on interest rates currently being offered for loans with similar terms and credit quality and with adjustments that the Corporation’s management believes a market participant would consider in determining fair value. Loans were classified by type, s uch as commercial, residential mortgage, and automobile. These asset categories were further segmented into fixed- and adjustable-rate categories. Valuations are carried out based on categories and not on a loan-by-loan basis. The fair values of performin g fixed-rate and adjustable-rate loans were calculated by discounting expected cash flows through the estimated maturity date. This fair value is not currently an indication of an exit price as that type of assumption could result in a different fair value estimate. The fair value s of credit card loans w ere estimated using a discounted cash flow method and excludes any value related to a customer account relationship. Other loans with no stated maturity, like credit lines, were valued at book value. Prepaymen t assumptions were considered for non-residential loans. For residential mortgage loans, prepayment estimates were based on a prepayment model that combined both a historical calibration and current market prepayment expectations. Discount rates were based on the U.S. Treasury and LIBOR/Swap Yield Curves at the date of the analysis, and included appropriate adjustments for expected credit losses and liquidity. For impaired collateral dependent loans, the impairment was primarily measured based on the fair v alue of the collateral, which is derived from appraisals that take into consideration prices in observable transactions involving similar assets in similar locations. Deposits The estimated fair value s of demand deposits and savings accounts, which are deposits with no defined maturities, equals the amount payable on demand at the reporting date. The fair values of retail fixed-rate time deposits, with stated maturities, are base d on the present value of the future cash flows expected to be paid on the deposits. The cash flows were based on contractual maturities; no early repayments were assumed. Discount rates were based on the LIBOR yield curve. The estimated fair value of total deposits excludes the fair value of core deposit intangibles, which represent the value of the customer relationship. The fair value of total deposits is measured by the value of demand deposits and savings deposits that bear a low or zero rate of in terest and do not fluctuate in response to changes in interest rates. The fair value s of brokered CDs, which are included within deposits, are determined using discounted cash flow analyses over the full term s of the CDs. The fair value s of the CDs are com puted using the outstanding principal amount. The discount rates used were based on brokered CD market rates as of September 30, 2017 . The fair value s do not incorporate the risk of nonperformance, since interests in brokered CDs are generally sold b y brokers in amounts of less than $ 250,000 and, therefore, are insured by the FDIC. Securities sold under agreements to repurchase Some repurchase agreements reprice at least quarterly, and their outstanding balances are estimated to be their fair value . Where longer commitments are involved, fair values are estimated using exit price indications of the cost of unwinding the transactions as of the end of the reporting period. The brokers who are the counterparties provide these indications, which the Corpo ration evaluates. Securities sold under agreements to repurchase are fully collateralized by investment securities. Advances from the FHLB The fair values of advances from the FHLB with fixed maturities are determined using discounted cash flow analyses ov er the full terms of the borrowings, using indications of the fair value of similar transactions. The cash flows assume no early repayment of the borrowings. Discount rates are based on the LIBOR yield curve. Advances from the FHLB are fully collateralize d by mortgage loans and, to a lesser extent, investment securities. Other borrowings Other borrowings consist of junior subordinated debentures. Projected cash flows from the debentures were discounted using the Bloomberg BB Finance curve plus a credit spread. This credit spread was estimated using the difference in yield curves between swap rates and a yield curve that considers the industry and credit rating of the Corporation as issuer of the debentures at a tenor comparable to the time to maturity of the debentures.

SEGMENT INFORMATION

SEGMENT INFORMATION	9 Months Ended
	Sep. 30, 2017
SEGMENT INFORMATION	NOTE 24 – SEGMENT INFORMATION Based upon the Corporation’s organizational structure and the information provided to the Chief Executive Officer of the Corporation and, to a lesser extent, the Board of Directors, the operating segments are driven primarily by 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 September 30, 2017 , the Corporation had six reportable seg ments: Commercial and Corporate Banking; Mortgage Banking; Consumer (Retail) Banking; Treasury and Investments; United States Operations; and Virgin Islands Operations. Management determined the reportable segments based on the internal reporting used to evaluate performance and to assess where to allocate resources. Other factors such as the Corporation’s organizational chart, nature of the products, distribution channels, and the economic characteristics of the products were also considered in the determ ination of the reportable segments. The Commercial and Corporate Banking segment consists of the Corporation’s lending and other services for large customers represented by specialized and middle-market clients and the public sector. The Commercial and Co rporate Banking segment offers commercial loans, including commercial real estate and construction loans, and floor plan financings, as well as other products, such as cash management and business management services. The Mortgage Banking segment consists of the origination, sale, and servicing of a variety of residential mortgage loans. The Mortgage Banking segment also acquires and sells mortgages in the secondary markets. In addition, the Mortgage Banking segment includes mortgage loans purchased from o ther local banks and mortgage bankers. The Consumer (Retail) Banking segment consists of the Corporation’s consumer lending and deposit-taking activities conducted mainly through its branch network and loan centers. The Treasury and Investments segment is responsible for the Corporation’s investment portfolio and treasury functions 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 t heir lending activities and borrows from those segments. The Consumer (Retail) Banking and the United States Operations segments also lend funds to the other segments. The interest rates charged or credited by Treasury and Investments, the Consumer (Retail) B anking 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, “Basis of Presentation and Signif icant Accounting Policies,” in the audited consolidated financial statements of the Corporation for the year ended December 31, 2016, which are included in the Corporation’s 2016 Annual Report on Form 10-K. The Corporation evaluates the performance of th e 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. The following table presents information about the reportable segments: (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended September 30, 2017: Interest income $ 32,317 $ 43,769 $ 31,083 $ 13,374 $ 18,446 $ 9,006 $ 147,995 Net (charge) credit for transfer of funds (11,268) 9,351 (8,748) 11,198 (533) - - Interest expense - (6,520) - (12,924) (4,932) (787) (25,163) Net interest income 21,049 46,600 22,335 11,648 12,981 8,219 122,832 (Provision) release for loan and lease losses (20,495) (33,067) (13,621) - (789) (7,041) (75,013) Non-interest income 2,908 11,242 1,014 1,459 697 1,325 18,645 Direct non-interest expenses (8,174) (27,193) (8,102) (1,014) (7,605) (7,254) (59,342) Segment (loss) income $ (4,712) $ (2,418) $ 1,626 $ 12,093 $ 5,284 $ (4,751) $ 7,122 Average earning assets $ 2,434,963 $ 1,758,653 $ 2,477,266 $ 2,228,990 $ 1,581,726 $ 602,366 $ 11,083,964 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total For the quarter ended September 30, 2016: Interest income $ 34,605 $ 44,455 $ 28,981 $ 12,529 $ 13,944 $ 9,059 $ 143,573 Net (charge) credit for transfer of funds (12,074) 2,810 (6,700) 15,839 125 - - Interest expense - (6,323) - (14,487) (3,811) (774) (25,395) Net interest income 22,531 40,942 22,281 13,881 10,258 8,285 118,178 (Provision) release for loan and lease losses (3,860) (8,655) (8,162) - 2,024 (2,850) (21,503) Non-interest income 5,222 11,292 985 6,154 884 1,609 26,146 Direct non-interest expenses (8,864) (27,100) (11,871) (914) (7,556) (7,097) (63,402) Segment income $ 15,029 $ 16,479 $ 3,233 $ 19,121 $ 5,610 $ (53) $ 59,419 Average earning assets $ 2,549,358 $ 1,973,424 $ 2,410,037 $ 2,565,019 $ 1,252,271 $ 604,150 $ 11,354,259 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total Nine-Month Period Ended September 30, 2017 Interest income $ 99,361 $ 130,055 $ 90,858 $ 41,788 $ 50,910 $ 27,625 $ 440,597 Net (charge) credit for transfer of funds (34,466) 20,799 (27,071) 41,858 (1,120) - - Interest expense - (18,603) - (36,842) (13,499) (2,368) (71,312) Net interest income 64,895 132,251 63,787 46,804 36,291 25,257 369,285 Provision for loan and lease losses (40,598) (47,976) (20,906) - (885) (8,186) (118,551) Non-interest income (loss) 11,258 37,224 2,972 (10,273) 1,776 4,480 47,437 Direct non-interest expenses (27,675) (82,677) (27,240) (3,190) (23,579) (20,922) (185,283) Segment income $ 7,880 $ 38,822 $ 18,613 $ 33,341 $ 13,603 $ 629 $ 112,888 Average earning assets $ 2,469,037 $ 1,771,376 $ 2,500,180 $ 2,176,164 $ 1,492,727 $ 609,765 $ 11,019,249 (In thousands) Mortgage Banking Consumer (Retail) Banking Commercial and Corporate Treasury and Investments United States Operations Virgin Islands Operations Total Nine-Month Period Ended September 30, 2016 Interest income $ 104,865 $ 135,655 $ 93,915 $ 39,206 $ 40,091 $ 27,606 $ 441,338 Net (charge) credit for transfer of funds (37,673) 10,546 (18,212) 44,226 1,113 - - Interest expense - (18,765) - (45,828) (11,214) (2,477) (78,284) Net interest income 67,192 127,436 75,703 37,604 29,990 25,129 363,054 (Provision) release for loan and lease losses (21,608) (24,451) (17,730) - 1,563 (1,316) (63,542) Non-interest income 14,381 35,318 2,459 3,815 2,799 5,621 64,393 Direct non-interest expenses (29,828) (87,218) (33,194) (3,462) (23,070) (20,757) (197,529) Segment income $ 30,137 $ 51,085 $ 27,238 $ 37,957 $ 11,282 $ 8,677 $ 166,376 Average earning assets $ 2,576,194 $ 1,989,426 $ 2,489,268 $ 2,774,118 $ 1,188,463 $ 613,666 $ 11,631,135 The following table presents a reconciliation of the reportable segment financial information to the consolidated totals: Quarter Ended Nine-Month Period Ended September 30, September 30, 2017 2016 2017 2016 Net income : Total segment income $ 7,122 $ 59,419 $ 112,888 $ 166,376 Other operating expenses (1) (26,272) (24,901) (77,282) (73,315) (Loss) income before income taxes (19,150) 34,518 35,606 93,061 Income tax benefit (expense) 8,398 (10,444) 7,181 (23,690) Total consolidated net (loss) income $ (10,752) $ 24,074 $ 42,787 $ 69,371 Average assets: Total average earning assets for segments $ 11,083,964 $ 11,354,259 $ 11,019,249 $ 11,631,135 Average non-earning assets 900,334 926,043 896,071 927,732 Total consolidated average assets $ 11,984,298 $ 12,280,302 $ 11,915,320 $ 12,558,867 (1) Expenses pertaining to corporate administrative functions that support the operating segments but are not specifically attributable to or managed by any segment are not included in the reported financial results of the operating segments.

REGULATORY MATTERS, COMMITMENTS

REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES	9 Months Ended
	Sep. 30, 2017
REGULATORY MATTERS, COMMITMENTS AND CONTINGENCIES	NOTE 25 – 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. 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 pract ices. 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, t he New York FED has terminated the Written A gr eement entered into on June 3, 2010 between 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 trust preferred securities, incurring or guaranteeing debt or purchasing or redeeming any corpora te stock. Although the Corporation and FirstBank became subject to the U.S. Basel III capital rules (“Basel III rules”) beginning on January 1, 2015, certain requirements of the Basel III rules are being phased in over several years. The phase-in period for certain deductions and adjustments to regulatory capital (such as certain intangible assets and deferred tax assets that arise from net operating losses and tax credit carryforwards) will be completed on January 1, 2018. 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 distribution s (e.g. repurchases of capital instruments or dividend or 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 Janu ary 1, 2016 with a first year requirement of 0.625 % of additional Common Equity Tier 1 Capital (“CET1”), which is being progressively increased over a four-year period, increasing by that same percentage amount on each subsequent January 1 until it reaches 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, the Corporation will be required to maintain: (i) a minimum CET1 capital to risk-weighted asset s 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 buf fer, 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 trust preferred securities (“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. Please refer to the discussion in “Pa rt I – Item 7 – Business – Supervision and Regulation” included in the Corporation’s 2016 Form 10-K for a more complete discussion of supervision and regulatory matters and activities that affect the Corporation and its subsidiaries. The Corporation's and its banking subsidiary's regulatory capital positions as of September 30, 2017 and December 31, 2016 were as follows: Regulatory Requirements Actual For Capital Adequacy Purposes To be Well-Capitalized-General Thresholds Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) As of September 30, 2017 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 1,957,282 22.18% $ 705,895 8.0% N/A N/A FirstBank $ 1,914,708 21.71% $ 705,618 8.0% $ 882,022 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,642,777 18.62% $ 397,066 4.5% N/A N/A FirstBank $ 1,530,926 17.36% $ 396,910 4.5% $ 573,314 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 1,642,777 18.62% $ 529,421 6.0% N/A N/A FirstBank $ 1,802,621 20.44% $ 529,213 6.0% $ 705,618 8.0% Leverage ratio First BanCorp. $ 1,642,777 13.96% $ 470,583 4.0% N/A N/A FirstBank $ 1,802,621 15.34% $ 469,985 4.0% $ 587,481 5.0% As of December 31, 2016 Total Capital (to Risk-Weighted Assets) First BanCorp. $ 1,921,329 21.34% $ 720,329 8.0% N/A N/A FirstBank $ 1,872,120 20.80% $ 720,091 8.0% $ 900,114 10.0% Common Equity Tier 1 Capital (to Risk-Weighted Assets) First BanCorp. $ 1,597,117 17.74% $ 405,185 4.5% N/A N/A FirstBank $ 1,523,332 16.92% $ 405,051 4.5% $ 585,074 6.5% Tier I Capital (to Risk-Weighted Assets) First BanCorp. $ 1,597,117 17.74% $ 540,247 6.0% N/A N/A FirstBank $ 1,757,642 19.53% $ 540,068 6.0% $ 720,091 8.0% Leverage ratio First BanCorp. $ 1,597,117 13.70% $ 466,376 4.0% N/A N/A FirstBank $ 1,757,642 15.10% $ 465,740 4.0% $ 582,174 5.0% The Corporation enters into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments may include commitments to extend credit and commitments to sell mortgage loans at fair value. As of September 3 0 , 201 7 , commitments to extend credit amounted to approximately $ 1.1 b illion, of which $ 663.4 million relates to credit card loans. Commercial and Financial standby letters of credit amounted to approximately $ 45.1 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 c ommitments 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. Generally, the Corporation do es not enter into interest rate lock agreements with pros pective borrowers in connection with its mortgage banking activities . As of September 30, 2017, 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 Co rporation 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 wh ere 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 of multiple defendants in some of the current proceedings 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 p roceedings. 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 informat ion 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 at September 30, 2017, 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 cons olidated financial position on a particular period. Ramirez Torres, et al. v Banco Popular de Puerto Rico, et al. FirstBank Puerto Rico has been named a defendant in a class action complaint captioned Ramirez Torres , et al. v. Banco Popular de Puerto Ric o, et al. The complaint seeks damages and preliminary and permanent injunctive relief on behalf of the purported class against Banco Popular de Puerto Rico and other financial institutions with insurance agency subsidiaries in Puerto Rico. Plaintiffs conte nd that in November 2015, Antilles Insurance Company obtained approval from the Puerto Rico Insurance Commissioner to market an endorsement that allowed its customers to obtain a reimbursement on their insurance premium for good experience, but that defend ants failed to offer this product or disclose its existence to their customers, favoring other products instead, in violation of their fiduciary duties as insurance producers. Plaintiffs seek a determination that defendants unlawfully failed to comply with their fiduciary duty to disclose the existence of this new insurance benefit from this carrier, as well as double or treble damages (the latter subject to a determination that defendants engaged in anti-monopolistic practices in failing to offer this prod uct). On July 31, 2017, the court entered judgment dismissing the complaint with prejudice. On August 30, 2017, Plaintiffs filed an Appeal before the Court of Appeals and FirstBank filed its opposition. Writ of Appeal is currently under the Court ’ s advisement.

Allowance For Loan And Lease Losses Natural Disasters Methodology And Assumptions		As described in Note 2 – “Natural Disasters Affecting First BanCorp. in Third Quarter 2017” two strong hurricanes affected the Corporation’s service areas during September 2017.  These storms caused widespread property damage, flooding, power outages, and water and communication services interruptions, and severely disrupted normal economic activity in the affected areas. Damages associated with the storm-related events will have significant short-term economic repercussions, both positive and negative, for the Corporation’ s commercial and individual loan customers in the most severely affected parts of Puerto Rico and the Virgin Islands. While these events have affected certain asset quality metrics, including higher delinquencies and non-performing loans, the storms’ ultimate effect on loan collections is uncertain. However, the Corporation’s loan officers are making individual storm-impact assessments for all commercial customers. The recent occurrence of the events makes it difficult to estimate the immediate impact at such level. The expectation is that the assessment will be substantially completed by the fourth quarter of 2017. The Corporation’s loan portfolio in Puerto Rico and the Virgin Islands totaled $7.3 billion as of September 30, 2017, or 82% of the entire portfolio.  The composition of these loans generally reflects the composition of the entire portfolio, which is close to 60% of residential and consumer loans to individual customers and 40% of commercial and construction loans.  Management has determined a separate qualitative element of the allowance to represent the estimate of inherent losses associated with the impact of the storm-related events on the Corporation’s Puerto Rico and Virgin Islands loan portfolios. This estimate is judgmental and subject to changes as conditions evolve. This qualitative element of the allowance was determined based on the estimated impact the storms could have on current employment levels (e.g unemployment rate that doubles current levels in Puerto Rico based on statistics observed in the aftermath of similar natural disasters in the U.S mainland like Hurricane Katrina) economic activity in the Corporation’s geographic regions, and the time it could take for the affected regions to return to a more normalized operating environment. It is expected that the rebuilding efforts will stimulate economic activity and accelerate the pace of economic recovery from the hurricanes. The Corporation’s credit risk modeling framework used to determine the storm-related estimate is similar to the one used for benchmarking purposes as part of the annual Dodd-Frank Act Stress Testing (“DFAST”) regulatory exercise.  Models were developed following a regression modeling approach in which relationships between portfolio-level loss rates and key economic indicators were derived based on historical behavior.  These models went through an extensive model specification and selection process that resulted in the use of certain variables, such as the unemployment rate and the Puerto Rico Economic Activity Index, which showed the highest predictive power of potential losses in our outstanding loan portfolio. Resulting loss factors were assigned to the overall performing balance of each major loan portfolio category in the affected regions, resulting in a total charge of $66.5 million (composed of $59.2 million for Puerto Rico and $7.3 million for Virgin Islands) that consisted of: (i) a $13.7 million charge to the provision for residential mortgage loans, (ii) an $18.1 million charge to the provision of commercial mortgage loans, (iii) an $8.0 million charge to the provision for commercial and industrial loans, (iv) a $0.8 million charge to the provision for construction loans, and (v) a $25.9 million charge to the provision for consumer loans. Residential and consumer loans are underwritten principally on income streams, with collateral viewed as a second source of repayment.  The storms’ impact varies widely within the residential and consumer portfolio, with some individual borrowers experiencing the devastation of loss of both home and employment and others with both homes and jobs intact. Properties used as collateral generally require insurance, minimizing the potential loss from property damages. For the commercial portfolio, the Corporation conducted a preliminary review of all loans in the Puerto Rico and Virgin Islands regions in amounts over $10 million, which accounts for 74.5% of the total commercial portfolio of such regions, and determined that 100% of the real estate-backed loans have property insurance. As such, the Corporation understands that credit losses and/or credit deterioration will mainly occur from the overall economic effect the storms will have on the economy of Puerto Rico and the Virgin Islands. Estimates of the storms’ effect on loan losses will change over time as additional information becomes available, and any related revisions in the allowance calculation will be reflected in the provision for loan losses as they occur. Such revisions could be material.
