(1)Refer to Note 9, Derivatives and Hedging Activities for additional information. The following table presents the activity in the allowance for credit losses for debt securities HTM for the three and six months ended June 30, 2026 and 2025 (in thousands): | | | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended June 30, | | Six Months Ended June 30, | | 2026 | | 2025 | | 2026 | | 2025 | | Allowance for securities credit losses | | | | | | | | | Beginning balance | $ | (754) | | | $ | (898) | | | $ | (811) | | | $ | (967) | | | | | | | | | | | Benefit for credit losses | 91 | | | 89 | | | 148 | | | 158 | | | | | | | | | | | | | | | | | | | | | | | | | | | Total ending allowance balance | $ | (663) | | | $ | (809) | | | $ | (663) | | | $ | (809) | |
The Company monitors the credit quality of debt securities HTM on a quarterly basis through the use of internal credit analysis supplemented by external credit ratings. Credit ratings of BBB- or Baa3 or higher are considered investment grade. Where multiple ratings are available, the Company considers the lowest rating when determining the allowance for securities credit losses. Under this approach, the amortized cost of debt securities HTM at June 30, 2026, aggregated by credit quality indicator, are as follows (in thousands): | | | | | | | | | | | | | | | | | | | | Investment Grade | | Non-Investment Grade/Non-rated | | Total | | As of June 30, 2026 | | | | | | | | | | | | | | | | | | | State and municipal debt obligations | $ | 150,074 | | | $ | — | | | $ | 150,074 | | | Corporate debt securities | 32,601 | | | 13,406 | | | 46,007 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Non-agency commercial MBS | 1,058 | | | — | | | 1,058 | | | | | | | | | Total debt securities held-to-maturity | $ | 183,733 | | | $ | 13,406 | | | $ | 197,139 | |
There were no realized gains/losses on sale of debt securities AFS for the three and six months ended June 30, 2026, as compared to $56,000 realized losses for both the corresponding prior year periods. These realized gains/losses on debt securities are presented within Other and included within Total other income on the Consolidated Statements of Income. The amortized cost and estimated fair value of debt securities at June 30, 2026 by contractual maturity are shown below (in thousands): | | | | | | | | | | | | | June 30, 2026 | Amortized Cost (1) | | Estimated Fair Value | | Less than one year | $ | 64,385 | | | $ | 63,625 | | | Due after one year through five years | 108,490 | | | 104,690 | | | Due after five years through ten years | 215,288 | | | 215,267 | | | Due after ten years | 603,696 | | | 606,706 | | | $ | 991,859 | | | $ | 990,288 | |
(1)The amortized cost of AFS securities excludes the portfolio layer fair value hedge basis adjustments of $12.2 million at June 30, 2026. Actual maturities may differ from contractual maturities in instances where issuers have the right to call or prepay obligations with or without call or prepayment penalties. At June 30, 2026, corporate debt securities, state and municipal obligations, and asset-backed securities with an amortized cost, excluding the fair value hedge basis adjustments, of $190.2 million, $166.4 million, and $461.1 million, respectively, and an estimated fair value of $190.8 million, $173.4 million, and $461.0 million, respectively, were callable prior to the maturity date. Mortgage-backed securities are excluded from the above table since their effective lives are expected to be shorter than the contractual maturity date due to principal prepayments. The estimated fair value and unrealized losses for debt securities AFS and HTM at June 30, 2026 and December 31, 2025, segregated by the duration of the unrealized losses, are as follows (in thousands): | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Less than 12 months | | 12 months or longer | | Total | | Estimated Fair Value | | Unrealized Losses (1) | | Estimated Fair Value | | Unrealized Losses (1) | | Estimated Fair Value | | Unrealized Losses (1) | | At June 30, 2026 | | | | | | | | | | | | Debt securities AFS: | | | | | | | | | | | | | U.S. government and agency obligations | $ | — | | | $ | — | | | $ | 52,087 | | | $ | (2,544) | | | $ | 52,087 | | | $ | (2,544) | | | | | | | | | | | | | | | Corporate debt securities | 48,005 | | | (150) | | | 993 | | | (8) | | | 48,998 | | | (158) | | | Asset-backed securities | 243,820 | | | (157) | | | — | | | — | | | 243,820 | | | (157) | | MBS: | | | | | | | | | | | | | Agency residential | 730,312 | | | (12,322) | | | — | | | — | | | 730,312 | | | (12,322) | | | Agency commercial | 485 | | | (3) | | | 97,611 | | | (9,446) | | | 98,096 | | | (9,449) | | Total MBS | 730,797 | | | (12,325) | | | 97,611 | | | (9,446) | | | 828,408 | | | (21,771) | | Total debt securities AFS | 1,022,622 | | | (12,632) | | | 150,691 | | | (11,998) | | | 1,173,313 | | | (24,630) | | Debt securities HTM: | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | State and municipal debt obligations | 4,911 | | | (59) | | | 125,489 | | | (7,096) | | | 130,400 | | | (7,155) | | | Corporate debt securities | 992 | | | (1) | | | 15,768 | | | (397) | | | 16,760 | | | (398) | | | | | | | | | | | | | | MBS: | | | | | | | | | | | | | Agency residential | 1,089,549 | | | (3,555) | | | 348,410 | | | (46,233) | | | 1,437,959 | | | (49,788) | | | Agency commercial | 34,016 | | | (116) | | | 66,317 | | | (6,111) | | | 100,333 | | | (6,227) | | | Non-agency commercial | — | | | — | | | 975 | | | (83) | | | 975 | | | (83) | | Total MBS | 1,123,565 | | | (3,671) | | | 415,702 | | | (52,427) | | | 1,539,267 | | | (56,098) | | Total debt securities HTM | 1,129,468 | | | (3,731) | | | 556,959 | | | (59,920) | | | 1,686,427 | | | (63,651) | | | Total debt securities | $ | 2,152,090 | | | $ | (16,363) | | | $ | 707,650 | | | $ | (71,918) | | | $ | 2,859,740 | | | $ | (88,281) | | | At December 31, 2025 | | | | | | | | | | | | Debt securities AFS: | | | | | | | | | | | | | U.S. government and agency obligations | $ | — | | | $ | — | | | $ | 51,941 | | | $ | (2,666) | | | $ | 51,941 | | | $ | (2,666) | | | Corporate debt securities | 4,712 | | | (97) | | | 3,798 | | | (201) | | | 8,510 | | | (298) | | | Asset-backed securities | 68,805 | | | (161) | | | — | | | — | | | 68,805 | | | (161) | | MBS: | | | | | | | | | | | | | Agency residential | 498,047 | | | (3,771) | | | 21,547 | | | (59) | | | 519,594 | | | (3,830) | | | Agency commercial | — | | | — | | | 98,518 | | | (9,061) | | | 98,518 | | | (9,061) | | Total MBS | 498,047 | | | (3,771) | | | 120,065 | | | (9,120) | | | 618,112 | | | (12,891) | | Total debt securities AFS | 571,564 | | | (4,029) | | | 175,804 | | | (11,987) | | | 747,368 | | | (16,016) | | Debt securities HTM: | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | State and municipal debt obligations | 245 | | | — | | | 138,624 | | | (8,518) | | | 138,869 | | | (8,518) | | | Corporate debt securities | 4,458 | | | (241) | | | 14,295 | | | (451) | | | 18,753 | | | (692) | | | | | | | | | | | | | | MBS: | | | | | | | | | | | | | Agency residential | 23,548 | | | (72) | | | 425,748 | | | (44,449) | | | 449,296 | | | (44,521) | | | Agency commercial | — | | | — | | | 71,509 | | | (5,256) | | | 71,509 | | | (5,256) | | | Non-agency commercial | 459 | | | (1) | | | 989 | | | (82) | | | 1,448 | | | (83) | | Total MBS | 24,007 | | | (73) | | | 498,246 | | | (49,787) | | | 522,253 | | | (49,860) | | Total debt securities HTM | 28,710 | | | (314) | | | 651,165 | | | (58,756) | | | 679,875 | | | (59,070) | | | Total debt securities | $ | 600,274 | | | $ | (4,343) | | | $ | 826,969 | | | $ | (70,743) | | | $ | 1,427,243 | | | $ | (75,086) | |
(1)The unrealized losses of AFS securities excludes the portfolio layer fair value hedge basis adjustments of $12.2 million and $4.0 million at June 30, 2026 and December 31, 2025, respectively. The Company concluded that no debt securities were impaired at June 30, 2026 based on consideration of several factors. As of June 30, 2026, the Company had one non-performing investment of $20.6 million acquired from Flushing, for which full recovery is expected. Except for this investment, the Company noted that each issuer made all contractually due payments when required. There were no defaults on principal or interest payments, and no interest payments were deferred. Based on management’s analysis of each individual security, the issuers appear to have the ability to meet debt service requirements over the life of the security. Furthermore, the net unrealized losses were primarily due to changes in the general credit and interest rate environment and not credit quality. Additionally, the Company has not utilized securities sales as a source of liquidity and the Company’s liquidity plans include adequate sources of liquidity outside securities sales. Equity Investments At June 30, 2026 and December 31, 2025, the Company held equity investments of $76.0 million and $91.9 million, respectively. The equity investments are primarily comprised of investments in other financial institutions and funds, and select financial services institutions’ preferred stocks. The realized and unrealized gains or losses on equity securities for the three and six months ended June 30, 2026 and 2025 are shown in the table below (in thousands): | | | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended June 30, | | Six Months Ended June 30, | | 2026 | | 2025 | | 2026 | | 2025 | | Net (loss) gain on equity investments | $ | (347) | | | $ | 488 | | | $ | (701) | | | $ | 693 | | | Less: Net loss recognized on equity investments sold | (455) | | | — | | | (455) | | | — | | | Unrealized gains (losses) recognized on equity investments still held | $ | 108 | | | $ | 488 | | | $ | (246) | | | $ | 693 | | | | | | | | | |
