Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations OFG is a publicly-owned financial holding company incorporated under the laws of the Commonwealth of Puerto Rico. OFG operates through various subsidiaries including, a commercial bank, Oriental Bank (the “Bank”), a securities broker-dealer and investment adviser, Oriental Financial Services LLC (“Oriental Financial Services”), an insurance agency, Oriental Insurance, LLC (“Oriental Insurance”), a captive reinsurance company, OFG Reinsurance Ltd (“OFG Reinsurance”), and OFG Ventures LLC (“OFG Ventures”), which holds investments. Through these subsidiaries and their respective divisions, OFG provides a wide range of banking and financial services such as commercial, consumer, auto, and mortgage lending, financial planning, insurance sales, investment advisory, and securities brokerage services, as well as corporate and individual trust services. The Bank has a wholly-owned operating subsidiary, OFG USA LLC, which is a commercial lender organized in Delaware. In addition, Oriental International Bank Inc. (“OIB”), a wholly-owned subsidiary of the Bank, and Oriental Overseas, a division of the Bank, are international banking entities licensed pursuant to the International Banking Center Regulatory Act of Puerto Rico, as amended. OIB and Oriental Overseas offer the Bank certain Puerto Rico tax advantages. Their activities are limited under Puerto Rico law to persons located in Puerto Rico with assets/liabilities located outside of Puerto Rico. During the quarter ended March 31, 2024, the Bank organized OBPEF LLC, as a wholly-owned subsidiary of the Bank and a private equity fund under the Puerto Rico Incentives Code, as amended, which objective is to provide financing to eligible borrowers, whether in the form of senior or subordinated debt, to support the economic development of Puerto Rico. Basis of Presentation The accompanying unaudited consolidated financial statements of OFG have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission (“SEC”). Accordingly, these consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows of OFG on a consolidated basis, and all such adjustments are of a normal recurring nature. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in OFG’s annual report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Form 10-K”). Operating results for the quarter ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. OFG evaluated subsequent events through the filing date of this report with the SEC and has recorded or disclosed those material events or transactions as described within the accompanying consolidated financial statements and notes. Material estimates that are particularly susceptible to significant change in the near term relate mainly to the determination of the allowance for credit losses. New Accounting Updates Not Yet Adopted Segment Reporting—Improvements to Reportable Segment Disclosures. In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07 to enhance segment reporting by expanding the breadth and frequency of segment disclosures required for public entities. The amendments in this ASU will allow registrants to disclose multiple measures of segment profit or loss and it also clarifies that single reportable segment entities must apply Topic 280 in its entirety. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The amendments will be effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We will adopt this guidance when it becomes effective in the annual period of 2024 on a retrospective basis to all periods presented in the financial statements, and the impact on our financial statements and disclosures is not expected to be material. Income Taxes—Improvements to Income Tax Disclosures. In December 2023, the FASB issued ASU 2023-09 to enhance income tax disclosures and address investor requests for more information about the tax risks and opportunities present in an entity’s worldwide operations. The ASU’s two primary enhancements will require further disaggregation for existing disclosures for the effective tax rate reconciliation and income taxes paid. More specifically, the amendments will require entities to disclose: a tabular effective tax rate reconciliation, broken out into specific categories with certain reconciling items above a 5% threshold further broken out by nature and jurisdiction; and income taxes paid (net of refunds received), broken out between federal, state and foreign, and net amounts paid to an individual jurisdiction that exceed 5% of the total. The amendments in this update are effective for annual periods beginning after December 15, 2024. Entities are permitted to early adopt these amendments. The amendments should be applied prospectively, but retrospective application is permitted. We will adopt this guidance when it becomes effective, in the annual period of 2025 on a prospective basis, and the impact on our financial statements and disclosures is not expected to be material. The Enhancement and Standardization of Climate-Related Disclosures for Investors. On March 6, 2024, the SEC issued a final rule under SEC Release No. 33-11275 that requires registrants to provide climate disclosures in their annual reports and registration statements. The rule includes disclosure concerning the use of carbon offsets or renewable energy credits or certificates if their use is a material component of the registrant’s plans to achieve its disclosed climate-related targets or goals, and certain disclosures about Scope 1 and/or Scope 2 greenhouse gas (“GHG”) emissions, if material. It also requires disclosures of amounts related to the effects of severe weather events and other natural conditions. The disclosure requirements will apply to OFG's fiscal year beginning January 1, 2025. We will adopt this rule when it becomes effective. OFG is currently evaluating the final rule but the impact on our financial statements and disclosures is not expected to be material.
