Fair Value Disclosures
Fair Value Measurement	Note 24 – Fair value measurement 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 judgements 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 2022 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. Fair Value on a Recurring and Nonrecurring Basis The following fair value hierarchy tables present information about the Corporation’s assets and liabilities measured at fair value on a recurring basis at March 31, 2023 and December 31, 2022: At March 31, 2023 (In thousands) Level 1 Level 2 Level 3 Measured at NAV Total RECURRING FAIR VALUE MEASUREMENTS Assets Debt securities available-for-sale: U.S. Treasury securities $ 1,865,470 $ 8,769,277 $ - $ - $ 10,634,747 Collateralized mortgage obligations - federal agencies - 158,772 - - 158,772 Mortgage-backed securities - 6,377,905 655 - 6,378,560 Other - 49 1,000 - 1,049 Total debt securities available-for-sale $ 1,865,470 $ 15,306,003 $ 1,655 $ - $ 17,173,128 Trading account debt securities, excluding derivatives: U.S. Treasury securities $ 15,462 $ - $ - $ - $ 15,462 Obligations of Puerto Rico, States and political subdivisions - 62 - - 62 Collateralized mortgage obligations - 45 88 - 133 Mortgage-backed securities - 13,779 188 - 13,967 Other - - 199 - 199 Total trading account debt securities, excluding derivatives $ 15,462 $ 13,886 $ 475 $ - $ 29,823 Equity securities $ - $ 32,545 $ - $ 318 $ 32,863 Mortgage servicing rights - - 127,475 - 127,475 Loans held-for-sale - 11,181 - - 11,181 Derivatives - 19,365 - - 19,365 Total assets measured at fair value on a recurring basis $ 1,880,932 $ 15,382,980 $ 129,605 $ 318 $ 17,393,835 Liabilities Derivatives $ - $ (17,115) $ - $ - $ (17,115) Total liabilities measured at fair value on a recurring basis $ - $ (17,115) $ - $ - $ (17,115) At December 31, 2022 (In thousands) Level 1 Level 2 Level 3 Measured at NAV Total RECURRING FAIR VALUE MEASUREMENTS Assets Debt securities available-for-sale: U.S. Treasury securities $ 1,908,589 $ 9,272,359 $ - $ - $ 11,180,948 Collateralized mortgage obligations - federal agencies - 165,196 - - 165,196 Mortgage-backed securities - 6,456,459 711 - 6,457,170 Other - 60 1,000 - 1,060 Total debt securities available-for-sale $ 1,908,589 $ 15,894,074 $ 1,711 $ - $ 17,804,374 Trading account debt securities, excluding derivatives: U.S. Treasury securities $ 13,069 $ - $ - $ - $ 13,069 Obligations of Puerto Rico, States and political subdivisions - 64 - - 64 Collateralized mortgage obligations - 47 113 - 160 Mortgage-backed securities - 14,008 215 - 14,223 Other - - 207 - 207 Total trading account debt securities, excluding derivatives $ 13,069 $ 14,119 $ 535 $ - $ 27,723 Equity securities $ - $ 29,302 $ - $ 330 $ 29,632 Mortgage servicing rights - - 128,350 - 128,350 Derivatives - 19,229 - - 19,229 Total assets measured at fair value on a recurring basis $ 1,921,658 $ 15,956,724 $ 130,596 $ 330 $ 18,009,308 Liabilities Derivatives $ - $ (17,000) $ - $ - $ (17,000) Total liabilities measured at fair value on a recurring basis $ - $ (17,000) $ - $ - $ (17,000) Beginning in the first quarter of 2023, the Corporation has elected the fair value option for BPPR mortgage loans held for sale. This election better aligns with the management of the portfolio from a business perspective. As of December 31, 2022, the Corporation had not elected the fair value option for any of the loans in the held for sale portfolio. Loans held-for-sale measured at fair value Loans held-for-sale measured at fair value were priced based on secondary market prices. These loans are classified as Level 2. The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for mortgage loans held for sale measured at fair value as of March 31,2023. (In thousands) March 31, 2023 Aggregate Unpaid Fair Value Principal Balance Difference Loans held for sale $ 11,181 $ 11,116 $ 65 No loans held for sell were 90 or more days past due or on nonaccrual status as of March 31,2023. During the quarter ended March 31,2023, the Corporation recognized an unrealized gain of $ 70 thousand for changes in the fair value of mortgage loans held for sale for which we elected the fair value option, that was offset by the changes in the fair value of the related hedging instrument, both of which are recorded within the mortgage banking activities line item of the accompanying Statement of Operations. The fair value information included in the following tables is not as of period end, but as of the date that the fair value measurement was recorded during the quarters ended March 31, 2023 and 2022 and excludes nonrecurring fair value measurements of assets no longer outstanding as of the reporting date.
