Accounting Policies
Consolidation	Basis of Presentation The consolidated interim financial statements have been prepared without audit. The Consolidated Statement of Financial Condition data at December 31, 2018 was derived from audited financial statements. The unaudited interim financial statements are, in the opinion of management, a fair statement of the results for the periods reported and include all necessary adjustments, all of a normal recurring nature, for a fair statement of such results. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted from the unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, these financial statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation for the year ended December 31, 2018, included in the Corporation’s 2018 Form 10-K. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.
Use of estimates	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
New accounting pronouncements policies	Recently Adopted Accounting Standards Updates FASB Accounting Standards Updates (“ASUs”), Leases (Topic 842) The FASB has issued a series of ASUs which, among other things, supersede ASC Topic 840 and set out the principles for the recognition, measurement, presentation and disclosure of leases for both lessors and lessees. The new guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset (“ROU asset”) and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases. In addition, the new leases standard requires lessors, among other things, to present lessor costs paid by the lessee to the lessor on a gross basis. The Corporation adopted the new leases standard during the first quarter of 2019 using the modified retrospective approach. The Corporation elected the practical expedients to not reassess at the date of adoption whether any existing contracts were or contained leases, their lease classification, and initial direct costs. The Corporation also elected the optional transition method that allows application of the transition provisions of the new leases standard at the adoption date, instead of at the earliest comparative period presented. Therefore, comparative periods will continue to be presented in accordance with ASC Topic 840. The Corporation also elected the optional practical expedients that permit the use of hindsight in evaluating lessee options to extend or terminate a lease, and to not apply ASC Topic 842 to all classes of short-term leases. On the other hand, the Corporation did not elect the practical expedient on not separating lease components from nonlease components. As of January 1, 2019, the Corporation recognized ROU assets of $139 million, net of deferred rent liability of $15 million and lease liabilities of $154 million on its operating leases. In addition, the Corporation recorded a positive cumulative effect adjustment of $4.8 million to retained earnings as a result of the reclassification of previously deferred gains on sale and operating lease back transactions. In addition, the Corporation early adopted ASU 2019-01 which, among other things, reinstates the specific fair value guidance in ASC Topic 840 for lessors that are not manufacturers or dealers to continue to measure the fair value of an underlying asset at its cost and clarifies that lessors that are depository or lending institutions in the scope of ASC Topic 942 are required to present the principal portion of lessee payments received from sales-type or direct financing leases as cash flows from investing activities. The Corporation was not impacted by the adoption of ASU 2019-01. FASB Accounting Standards Update (“ASU”) 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes The FASB issued ASU 2018-16 in October 2018 which permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to other permissible U.S. benchmark rates. The Corporation adopted ASU 2018-16 during the first quarter of 2019. As such, the Corporation will consider this guidance for qualifying new hedging relationships entered into on or after the effective date. FASB Accounting Standards Update (“ASU”) 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The FASB issued ASU 2018-02 in February 2018, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. These stranded tax effects result from recognizing in income the impact of changes in tax rates even when the related tax effects were recognized in accumulated other comprehensive income. The amendments also require certain disclosures about stranded tax effects. The Corporation adopted ASU 2018-02 during the first quarter of 2019. As of December 31, 2018, the Corporation maintained a full valuation allowance on the deferred tax assets, which were recognized in accumulated other comprehensive income related to its U.S. operations. As such, the Corporation was not impacted by the adoption of this accounting pronouncement during the first quarter of 2019. FASB Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The FASB issued ASU 2017-12 in August 2017, which makes more financial and nonfinancial hedging strategies eligible for hedge accounting and changes how companies assess effectiveness by, among other things, eliminating the requirement for entities to recognize hedge ineffectiveness each reporting period for cash flow hedges and requiring presentation of the changes in fair value of cash flow hedges in the same income statement line item(s) as the earnings effect of the hedged items when the hedged item affects earnings. The Corporation adopted ASU 2017-12 during the first quarter of 2019. The cumulative effect adjustment recorded to retained earnings to reverse the hedge ineffectiveness as of December 31, 2018 was not significant. There were no changes in presentation since the earnings effect of the hedges and the hedged items are already presented in the same income statement line item. In addition, the Corporation elected to continue to perform subsequent assessments of hedge effectiveness quantitatively. Additionally, adoption of the following standards effective during the first quarter of 2019 did not have a significant impact on the Corporation’s Consolidated Financial Statements: FASB Accounting Standards Update (“ASU”) 2018-09, Codification ImprovementsFASB Accounting Standards Update (“ASU”) 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment AccountingFASB Accounting Standards Update (“ASU”) 2017-11, Earnings per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): Part I: Accounting for Certain Financial Instruments with Down Round Features; Part II: Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope ExceptionFASB Accounting Standards Update (“ASU”) 2017-08, Receivables– Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt SecuritiesRecently Issued Accounting Standards Updates FASB Accounting Standards Update (“ASUs”) 2019-07, Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification and 33-10442, Investment Company Reporting Modernization, and Miscellaneous Updates The FASB issued ASU 2019-07 in July 2019, which updates the SEC portion of its codification literature with already effective SEC final rules that simplified disclosures and modernized the reporting and disclosure of information by registered investment companies. FASB Accounting Standards Updates (“ASUs”), Financial Instruments – Credit Losses (Topic 326) The FASB issued ASU 2016-13 in June 2016, which replaces the incurred loss model with a current expected credit loss (“CECL”) model. The CECL model applies to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet exposures. Under current U.S. GAAP, an entity reflects credit losses on financial assets measured on an amortized cost basis only when losses are probable and have been incurred, generally considering only past events and current conditions in making these determinations. ASU 2016-13 prospectively replaces this approach with a forward-looking methodology that reflects the expected credit losses over the lives of financial assets, starting when such assets are first acquired. Under the revised methodology, credit losses will be measured based on past events, current conditions and reasonable and supportable forecasts that affect the collectability of financial assets. ASU 2016-13 also revises the approach to recognizing credit losses for available-for-sale securities by replacing the direct write-down approach with the allowance approach and limiting the allowance to the amount at which the security’s fair value is less than the amortized cost. In addition, ASU 2016-13 provides that the initial allowance for credit losses on purchased credit impaired financial assets will be recorded as an increase to the purchase price, with subsequent changes to the allowance recorded as a credit loss expense. ASU 2016-13 also expands disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for credit losses. The FASB issued ASU 2019-05 in May 2019, which provides entities with an option to irrevocably elect the fair value option applied on an instrument-by-instrument basis for financial instruments within the scope of Topic 326, except for held-to-maturity debt securities, upon adoption of Topic 326. The FASB issued ASU 2019-04 in April 2019, which clarifies areas of guidance related to the recently issued standards on credit losses (Topic 326), derivatives and hedging (Topic 815), and recognition and measurement of financial instruments (Topic 825). Amendments to Topic 326 are mainly in the areas of accrued interest receivable, transfers of loans and debt securities between classifications, inclusion of expected recoveries in the allowance for credit losses and permitting a prepay-adjusted effective interest rate except for TDRs. Amendments to Topic 815 and Topic 825 are mainly in the areas of fair value hedges and equity securities accounted for under the measurement alternative, respectively. The FASB issued ASU 2018-19 in November 2018 which, among other things, clarifies that receivables arising from operating leases are not within the scope of ASC Topic 326. The amendments of these updates are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted as of January 1, 2019. The Corporation has continued its evaluation and implementation efforts with respect to CECL. Model development related to CECL has been substantially completed and is currently undergoing third-party validation procedures. Other implementation efforts are underway, including fulfillment of additional data needs for new disclosures and reporting requirements, related software implementation and the drafting of accounting policies. The ultimate impact of the adoption of CECL will depend on the composition of the Corporation’s portfolios as well as the economic conditions and forecast at the time of adoption. While day one estimates are still in process, based on preliminary analysis and the information currently available, the Corporation expects that its allowance for loan and lease losses would increase driven by the Puerto Rico mortgage and auto loans portfolio. This increase would be reflected as a decrease to the opening balance of retained earnings, net of income taxes, at adoption on January 1, 2020. The Corporation will avail itself of the option to phase in over a period of three years the day one effects on regulatory capital from the adoption of CECL and expects to continue to be well capitalized under the Basel III regulatory framework after the adoption of this standard. The day one preliminary estimate is subject to further work and analysis by the Corporation as part of its implementation efforts, including the consideration of qualitative factors, which may impact reserves, review of significant assumptions and the finalization of the model validation process. For other recently issued Accounting Standards Updates not yet effective, refer to Note 3 to the Consolidated Financial Statements included in the 2018 Form 10-K.
Revenue recognition	Revenue from contracts with customers is recognized when, or as, the performance obligations are satisfied by the Corporation by transferring the promised services to the customers. A service is transferred to the customer when, or as, the customer obtains control of that service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized based on the services that have been rendered to date. Revenue from a performance obligation satisfied at a point in time is recognized when the customer obtains control over the service. The transaction price, or the amount of revenue recognized, reflects the consideration the Corporation expects to be entitled to in exchange for those promised services. In determining the transaction price, the Corporation considers the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Corporation is the principal in a transaction if it obtains control of the specified goods or services before they are transferred to the customer. If the Corporation acts as principal, revenues are presented in the gross amount of consideration to which it expects to be entitled and are not netted with any related expenses. On the other hand, the Corporation is an agent if it does not control the specified goods or services before they are transferred to the customer. If the Corporation acts as an agent, revenues are presented in the amount of consideration to which it expects to be entitled, net of related expenses. Following is a description of the nature and timing of revenue streams from contracts with customers: Service charges on deposit accounts Service charges on deposit accounts are earned on retail and commercial deposit activities and include, but are not limited to, nonsufficient fund fees, overdraft fees and checks stop payment fees. These transaction-based fees are recognized at a point in time, upon occurrence of an activity or event or upon the occurrence of a condition which triggers the fee assessment. The Corporation is acting as principal in these transactions. Debit card fees Debit card fees include, but are not limited to, interchange fees, surcharging income and foreign transaction fees. These transaction-based fees are recognized at a point in time, upon occurrence of an activity or event or upon the occurrence of a condition which triggers the fee assessment. Interchange fees are recognized upon settlement of the debit card payment transactions. The Corporation is acting as principal in these transactions. Insurance fees Insurance fees include, but are not limited to, commissions and contingent commissions. Commissions and fees are recognized when related policies are effective since the Corporation does not have an enforceable right to payment for services completed to date. An allowance is created for expected adjustments to commissions earned related to policy cancellations. Contingent commissions are recorded on an accrual basis when the amount to be received is notified by the insurance company. The Corporation is acting as an agent since it arranges for the sale of the policies and receives commissions if, and when, it achieves the sale. Credit card fees Credit card fees include, but are not limited to, interchange fees, additional card fees, cash advance fees, balance transfer fees, foreign transaction fees, and returned payments fees. Credit card fees are recognized at a point in time, upon the occurrence of an activity or an event. Interchange fees are recognized upon settlement of the credit card payment transactions. The Corporation is acting as principal in these transactions. Sale and administration of investment products Fees from the sale and administration of investment products include, but are not limited to, commission income from the sale of investment products, asset management fees, underwriting fees, and mutual fund fees. Commission income from investment products is recognized on the trade date since clearing, trade execution, and custody services are satisfied when the customer acquires or disposes of the rights to obtain the economic benefits of the investment products and brokerage contracts have no fixed duration and are terminable at will by either party. The Corporation is acting as principal in these transactions since it performs the service of providing the customer with the ability to acquire or dispose of the rights to obtain the economic benefits of investment products. Asset management fees are satisfied over time and are recognized in arrears. At contract inception, the estimate of the asset management fee is constrained from the inclusion in the transaction price since the promised consideration is dependent on the market and thus is highly susceptible to factors outside the manager’s influence. As advisor, the broker-dealer subsidiary is acting as principal. Underwriting fees are recognized at a point in time, when the investment products are sold in the open market at a markup. When the broker-dealer subsidiary is lead underwriter, it is acting as an agent. In turn, when it is a participating underwriter, it is acting as principal. Mutual fund fees, such as distribution fees, are considered variable consideration and are recognized over time, as the uncertainty of the fees to be received is resolved as NAV is determined and investor activity occurs. The promise to provide distribution-related services is considered a single performance obligation as it requires the provision of a series of distinct services that are substantially the same and have the same pattern of transfer. When the broker-dealer subsidiary is acting as a distributor, it is acting as principal. In turn, when it acts as third-party dealer, it is acting as an agent. Trust fees Trust fees are recognized from retirement plan, mutual fund administration, investment management, trustee, escrow, and custody and safekeeping services. These asset management services are considered a single performance obligation as it requires the provision of a series of distinct services that are substantially the same and have the same pattern of transfer. The performance obligation is satisfied over time, except for optional services and certain other services that are satisfied at a point in time. Revenues are recognized in arrears, when, or as, the services are rendered. The Corporation is acting as principal since, as asset manager, it has the obligation to provide the specified service to the customer and has the ultimate discretion in establishing the fee paid by the customer for the specified services.
Fair value measurement policy	ASC Subtopic 820-10 “Fair Value Measurements and Disclosures” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels in order to increase consistency and comparability in fair value measurements and disclosures. The hierarchy is broken down into three levels based on the reliability of inputs as follows:Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Valuation on these instruments does not necessitate a significant degree of judgment since valuations are based on quoted prices that are readily available in an active market.Level 2 - Quoted prices other than those included in Level 1 that are observable either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or that can be corroborated by observable market data for substantially the full term of the financial instrument.Level 3 - Inputs are unobservable and significant to the fair value measurement. Unobservable inputs reflect the Corporation’s own assumptions about assumptions that market participants would use in pricing the asset or liability. The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Fair value is based upon quoted market prices when available. If listed prices or quotes are not available, the Corporation employs internally-developed models that primarily use market-based inputs including yield curves, interest rates, volatilities, and credit curves, among others. Valuation adjustments are limited to those necessary to ensure that the financial instrument’s fair value is adequately representative of the price that would be received or paid in the marketplace. These adjustments include amounts that reflect counterparty credit quality, the Corporation’s credit standing, constraints on liquidity and unobservable parameters that are applied consistently. There have been no changes in the Corporation’s methodologies used to estimate the fair value of assets and liabilities from those disclosed in the 2018 Form 10-K. The estimated fair value may be subjective in nature and may involve uncertainties and matters of significant judgment for certain financial instruments. Changes in the underlying assumptions used in calculating fair value could significantly affect the results.

Basis of Presentation

The consolidated interim financial statements have been prepared without audit. The Consolidated Statement of Financial Condition data at December 31, 2018 was derived from audited financial statements. The unaudited interim financial statements are, in the opinion of management, a fair statement of the results for the periods reported and include all necessary adjustments, all of a normal recurring nature, for a fair statement of such results.

Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted from the unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, these financial statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation for the year ended December 31, 2018, included in the Corporation’s 2018 Form 10-K. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Use of estimates

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

New accounting pronouncements policies

Recently Adopted Accounting Standards Updates

FASB Accounting Standards Updates (“ASUs”), Leases (Topic 842)

The FASB has issued a series of ASUs which, among other things, supersede ASC Topic 840 and set out the principles for the recognition, measurement, presentation and disclosure of leases for both lessors and lessees. The new guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset (“ROU asset”) and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases.

In addition, the new leases standard requires lessors, among other things, to present lessor costs paid by the lessee to the lessor on a gross basis.

The Corporation adopted the new leases standard during the first quarter of 2019 using the modified retrospective approach. The Corporation elected the practical expedients to not reassess at the date of adoption whether any existing contracts were or contained leases, their lease classification, and initial direct costs. The Corporation also elected the optional transition method that allows application of the transition provisions of the new leases standard at the adoption date, instead of at the earliest comparative period presented. Therefore, comparative periods will continue to be presented in accordance with ASC Topic 840. The Corporation also elected the optional practical expedients that permit the use of hindsight in evaluating lessee options to extend or terminate a lease, and to not apply ASC Topic 842 to all classes of short-term leases. On the other hand, the Corporation did not elect the practical expedient on not separating lease components from nonlease components.

As of January 1, 2019, the Corporation recognized ROU assets of $139 million, net of deferred rent liability of $15 million and lease liabilities of $154 million on its operating leases. In addition, the Corporation recorded a positive cumulative effect adjustment of $4.8 million to retained earnings as a result of the reclassification of previously deferred gains on sale and operating lease back transactions.

In addition, the Corporation early adopted ASU 2019-01 which, among other things, reinstates the specific fair value guidance in ASC Topic 840 for lessors that are not manufacturers or dealers to continue to measure the fair value of an underlying asset at its cost and clarifies that lessors that are depository or lending institutions in the scope of ASC Topic 942 are required to present the principal portion of lessee payments received from sales-type or direct financing leases as cash flows from investing activities. The Corporation was not impacted by the adoption of ASU 2019-01.

FASB Accounting Standards Update (“ASU”) 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes

The FASB issued ASU 2018-16 in October 2018 which permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to other permissible U.S. benchmark rates.

The Corporation adopted ASU 2018-16 during the first quarter of 2019. As such, the Corporation will consider this guidance for qualifying new hedging relationships entered into on or after the effective date.

FASB Accounting Standards Update (“ASU”) 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

The FASB issued ASU 2018-02 in February 2018, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. These stranded tax effects result from recognizing in income the impact of changes in tax rates even when the related tax effects were recognized in accumulated other comprehensive income. The amendments also require certain disclosures about stranded tax effects.

The Corporation adopted ASU 2018-02 during the first quarter of 2019. As of December 31, 2018, the Corporation maintained a full valuation allowance on the deferred tax assets, which were recognized in accumulated other comprehensive income related to its U.S. operations. As such, the Corporation was not impacted by the adoption of this accounting pronouncement during the first quarter of 2019.

FASB Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities

The FASB issued ASU 2017-12 in August 2017, which makes more financial and nonfinancial hedging strategies eligible for hedge accounting and changes how companies assess effectiveness by, among other things, eliminating the requirement for entities to recognize hedge ineffectiveness each reporting period for cash flow hedges and requiring presentation of the changes in fair value of cash flow hedges in the same income statement line item(s) as the earnings effect of the hedged items when the hedged item affects earnings.

The Corporation adopted ASU 2017-12 during the first quarter of 2019. The cumulative effect adjustment recorded to retained earnings to reverse the hedge ineffectiveness as of December 31, 2018 was not significant. There were no changes in presentation since the earnings effect of the hedges and the hedged items are already presented in the same income statement line item. In addition, the Corporation elected to continue to perform subsequent assessments of hedge effectiveness quantitatively.

Additionally, adoption of the following standards effective during the first quarter of 2019 did not have a significant impact on the Corporation’s Consolidated Financial Statements:

The FASB issued ASU 2019-07 in July 2019, which updates the SEC portion of its codification literature with already effective SEC final rules that simplified disclosures and modernized the reporting and disclosure of information by registered investment companies.

FASB Accounting Standards Updates (“ASUs”), Financial Instruments – Credit Losses (Topic 326)

The FASB issued ASU 2016-13 in June 2016, which replaces the incurred loss model with a current expected credit loss (“CECL”) model. The CECL model applies to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet exposures. Under current U.S. GAAP, an entity reflects credit losses on financial assets measured on an amortized cost basis only when losses are probable and have been incurred, generally considering only past events and current conditions in making these determinations. ASU 2016-13 prospectively replaces this approach with a forward-looking methodology that reflects the expected credit losses over the lives of financial assets, starting when such assets are first acquired. Under the revised

methodology, credit losses will be measured based on past events, current conditions and reasonable and supportable forecasts that affect the collectability of financial assets. ASU 2016-13 also revises the approach to recognizing credit losses for available-for-sale securities by replacing the direct write-down approach with the allowance approach and limiting the allowance to the amount at which the security’s fair value is less than the amortized cost. In addition, ASU 2016-13 provides that the initial allowance for credit losses on purchased credit impaired financial assets will be recorded as an increase to the purchase price, with subsequent changes to the allowance recorded as a credit loss expense.

ASU 2016-13 also expands disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for credit losses.

The FASB issued ASU 2019-05 in May 2019, which provides entities with an option to irrevocably elect the fair value option applied on an instrument-by-instrument basis for financial instruments within the scope of Topic 326, except for held-to-maturity debt securities, upon adoption of Topic 326.

The FASB issued ASU 2019-04 in April 2019, which clarifies areas of guidance related to the recently issued standards on credit losses (Topic 326), derivatives and hedging (Topic 815), and recognition and measurement of financial instruments (Topic 825). Amendments to Topic 326 are mainly in the areas of accrued interest receivable, transfers of loans and debt securities between classifications, inclusion of expected recoveries in the allowance for credit losses and permitting a prepay-adjusted effective interest rate except for TDRs. Amendments to Topic 815 and Topic 825 are mainly in the areas of fair value hedges and equity securities accounted for under the measurement alternative, respectively.

The FASB issued ASU 2018-19 in November 2018 which, among other things, clarifies that receivables arising from operating leases are not within the scope of ASC Topic 326.

The amendments of these updates are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted as of January 1, 2019.

The Corporation has continued its evaluation and implementation efforts with respect to CECL. Model development related to CECL has been substantially completed and is currently undergoing third-party validation procedures. Other implementation efforts are underway, including fulfillment of additional data needs for new disclosures and reporting requirements, related software implementation and the drafting of accounting policies.

The ultimate impact of the adoption of CECL will depend on the composition of the Corporation’s portfolios as well as the economic conditions and forecast at the time of adoption. While day one estimates are still in process, based on preliminary analysis and the information currently available, the Corporation expects that its allowance for loan and lease losses would increase driven by the Puerto Rico mortgage and auto loans portfolio. This increase would be reflected as a decrease to the opening balance of retained earnings, net of income taxes, at adoption on January 1, 2020. The Corporation will avail itself of the option to phase in over a period of three years the day one effects on regulatory capital from the adoption of CECL and expects to continue to be well capitalized under the Basel III regulatory framework after the adoption of this standard.

The day one preliminary estimate is subject to further work and analysis by the Corporation as part of its implementation efforts, including the consideration of qualitative factors, which may impact reserves, review of significant assumptions and the finalization of the model validation process.

For other recently issued Accounting Standards Updates not yet effective, refer to Note 3 to the Consolidated Financial Statements included in the 2018 Form 10-K.

Revenue recognition

Revenue from contracts with customers is recognized when, or as, the performance obligations are satisfied by the Corporation by transferring the promised services to the customers. A service is transferred to the customer when, or as, the customer obtains control of that service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized based on the services that have been rendered to date. Revenue from a performance obligation satisfied at a point in time is recognized when the customer obtains control over the service. The transaction price, or the amount of revenue recognized, reflects the consideration the Corporation expects to be entitled to in exchange for those promised services. In determining the transaction price, the Corporation considers the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Corporation is the principal in a transaction if it obtains control of the specified goods or services before they are transferred to the customer. If the Corporation acts as principal, revenues are presented in the gross amount of consideration to which it expects to be entitled and are not netted with any related expenses. On the other hand, the Corporation is an agent if it does not control the specified goods or services before they are transferred to the customer. If the Corporation acts as an agent, revenues are presented in the amount of consideration to which it expects to be entitled, net of related expenses.

Following is a description of the nature and timing of revenue streams from contracts with customers:

Service charges on deposit accounts

Service charges on deposit accounts are earned on retail and commercial deposit activities and include, but are not limited to, nonsufficient fund fees, overdraft fees and checks stop payment fees. These transaction-based fees are recognized at a point in time, upon occurrence of an activity or event or upon the occurrence of a condition which triggers the fee assessment. The Corporation is acting as principal in these transactions.

Debit card fees

Debit card fees include, but are not limited to, interchange fees, surcharging income and foreign transaction fees. These transaction-based fees are recognized at a point in time, upon occurrence of an activity or event or upon the occurrence of a condition which triggers the fee assessment. Interchange fees are recognized upon settlement of the debit card payment transactions. The Corporation is acting as principal in these transactions.

Insurance fees

Insurance fees include, but are not limited to, commissions and contingent commissions. Commissions and fees are recognized when related policies are effective since the Corporation does not have an enforceable right to payment for services completed to date. An allowance is created for expected adjustments to commissions earned related to policy cancellations. Contingent commissions are recorded on an accrual basis when the amount to be received is notified by the insurance company. The Corporation is acting as an agent since it arranges for the sale of the policies and receives commissions if, and when, it achieves the sale.

Credit card fees

Credit card fees include, but are not limited to, interchange fees, additional card fees, cash advance fees, balance transfer fees, foreign transaction fees, and returned payments fees. Credit card fees are recognized at a point in time, upon the occurrence of an activity or an event. Interchange fees are recognized upon settlement of the credit card payment transactions. The Corporation is acting as principal in these transactions.

Sale and administration of investment products

Fees from the sale and administration of investment products include, but are not limited to, commission income from the sale of investment products, asset management fees, underwriting fees, and mutual fund fees.

Commission income from investment products is recognized on the trade date since clearing, trade execution, and custody services are satisfied when the customer acquires or disposes of the rights to obtain the economic benefits of the investment products and brokerage contracts have no fixed duration and are terminable at will by either party. The Corporation is acting as principal in these transactions since it performs the service of providing the customer with the ability to acquire or dispose of the rights to obtain the economic benefits of investment products.

Asset management fees are satisfied over time and are recognized in arrears. At contract inception, the estimate of the asset management fee is constrained from the inclusion in the transaction price since the promised consideration is dependent on the market and thus is highly susceptible to factors outside the manager’s influence. As advisor, the broker-dealer subsidiary is acting as principal.

Underwriting fees are recognized at a point in time, when the investment products are sold in the open market at a markup. When the broker-dealer subsidiary is lead underwriter, it is acting as an agent. In turn, when it is a participating underwriter, it is acting as principal.

Mutual fund fees, such as distribution fees, are considered variable consideration and are recognized over time, as the uncertainty of the fees to be received is resolved as NAV is determined and investor activity occurs. The promise to provide distribution-related services is considered a single performance obligation as it requires the provision of a series of distinct services that are substantially the same and have the same pattern of transfer. When the broker-dealer subsidiary is acting as a distributor, it is acting as principal. In turn, when it acts as third-party dealer, it is acting as an agent.

Trust fees

Trust fees are recognized from retirement plan, mutual fund administration, investment management, trustee, escrow, and custody and safekeeping services. These asset management services are considered a single performance obligation as it requires the provision of a series of distinct services that are substantially the same and have the same pattern of transfer. The performance obligation is satisfied over time, except for optional services and certain other services that are satisfied at a point in time. Revenues are recognized in arrears, when, or as, the services are rendered. The Corporation is acting as principal since, as asset manager, it has the obligation to provide the specified service to the customer and has the ultimate discretion in establishing the fee paid by the customer for the specified services.

Fair value measurement policy

ASC Subtopic 820-10 “Fair Value Measurements and Disclosures” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels in order to increase consistency and comparability in fair value measurements and disclosures. The hierarchy is broken down into three levels based on the reliability of inputs as follows:Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Valuation on these instruments does not necessitate a significant degree of judgment since valuations are based on quoted prices that are readily available in an active market.Level 2 - Quoted prices other than those included in Level 1 that are observable either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or that can be corroborated by observable market data for substantially the full term of the financial instrument.Level 3 - Inputs are unobservable and significant to the fair value measurement. Unobservable inputs reflect the Corporation’s own assumptions about assumptions that market participants would use in pricing the asset or liability.

The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Fair value is based upon quoted market prices when available. If listed prices or quotes are not available, the Corporation employs internally-developed models that primarily use market-based inputs including yield curves, interest rates, volatilities, and credit curves, among others. Valuation adjustments are limited to those necessary to ensure that the financial instrument’s fair value is adequately representative of the price that would be received or paid in the marketplace. These adjustments include amounts that reflect counterparty credit quality, the Corporation’s credit standing, constraints on liquidity and unobservable parameters that are applied consistently. There have been no changes in the Corporation’s methodologies used to estimate the fair value of assets and liabilities from those disclosed in the 2018 Form 10-K.

The estimated fair value may be subjective in nature and may involve uncertainties and matters of significant judgment for certain financial instruments. Changes in the underlying assumptions used in calculating fair value could significantly affect the results.
