Non-GAAP Measures Definitions 32 OFG reports certain financial measures that are not in accordance with GAAP. These non-GAAP financial measures are provided as supplemental information to the financial measures in this report that are calculated and presented in accordance with GAAP. Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not audited. To mitigate these limitations, OFG has procedures in place to calculate these measures using the appropriate GAAP or regulatory components. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP. Non-GAAP Measures Definitions: Tangible Common Equity: Total stockholders’ equity less intangible assets. Tangible Common Equity / Tangible Assets: Total stockholders’ equity less intangible assets divided by total assets less intangible assets. Return on Average Tangible Common Equity (ROATCE): Calculated based on annualized income available to common shareholders for the period divided by average tangible common equity for the period. Pre-Provision Net Revenues (PPNR): Pre-provision net revenues is a non-GAAP measure calculated based on net interest income plus total non-interest income, net, less total non-interest expenses for the period. PPNR Return on Average Assets (PPNR ROAA): Pre-provision net revenues divided by average total assets. Efficiency Ratio: Calculated based on non-interest expense for the period divided by total net interest income and total banking and financial services revenues for the period. Core Deposits: Total deposits less brokered deposits. Non-interest Income, net (Core): Reflects total banking and financial service revenues. Total Core Revenues: Reflects net interest income plus non-interest income, net (core).
