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, 2024 (the “2024 Form 10-K”).

The ASU does not change the expense line items an entity presents on the face of the income statement, rather, it requires disaggregation of certain expense line items into specified categories in disclosures within the footnotes to the financial statements. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027.

The amendments in this update are effective for annual periods beginning after December 15, 2024. Entities are permitted to early adopt these amendments.

For publicly listed business entities, the amendments are effective for fiscal years beginning after December 15, 2024, including interim periods within those fiscal years.

In March 2024, the FASB issued ASU 2024-01 to improve GAAP by adding an illustrative example to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether profits interest and similar awards should be accounted for in accordance with Topic 718. The ASU 2024-01 is intended to reduce complexity and diversity in practice. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods.
