Investments, Debt and Equity Securities [Abstract]

Our investment securities portfolio consists of U.S. Treasury securities, obligations of state and political subdivisions, U.S. federal government agencies such as Government National Mortgage Association ("GNMA") and Small Business Administration ("SBA"), U.S. government-sponsored enterprises ("GSEs"), such as Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage Corporation ("FHLMC"), Federal Farm Credit Banks Funding Corporation and FHLB, U.S. Corporations and one asset-backed security collateralized by student loan pools. We also invest in residential and commercial mortgage-backed securities (“MBS”/"CMBS") and collateralized mortgage obligations (“CMOs”) issued or guaranteed by the GSEs, as reflected in the following table.

A summary of the amortized cost, fair value and allowance for credit losses related to securities held-to-maturity as of June 30, 2022 and December 31, 2021 is presented below.

Management measures expected credit losses on held-to-maturity securities collectively by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. With regard to MBSs and CMOs issued or guaranteed by the GSEs, and SBA-backed securities, we expect to receive all the contractual principal and interest on these securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. government. Accordingly, no allowance for credit losses has been recorded for these securities. With regard to securities issued by states and political subdivisions and corporate bonds, management considers: (i) issuer and/or guarantor credit ratings, (ii) historical probability of default and loss given default rates for given bond ratings and remaining maturity, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) internal credit review of the financial information, and (v) whether or not such securities have credit enhancements such as guarantees, contain a defeasance clause, or are pre-refunded by the issuers. Based on the comprehensive analysis, no credit losses are expected.

The following table summarizes the amortized cost of our portfolio of held-to-maturity securities issued by states and political subdivisions and corporate bonds by Moody's and/or Standard & Poor's bond ratings as of June 30, 2022.

1 Amortized cost and fair value exclude accrued interest receivable of $3.4 million and $3.7 million at June 30, 2022 and December 31, 2021, respectively, which is included in interest receivable and other assets in the consolidated statements of condition.

As part of our ongoing review of our investment securities portfolio, we reassessed the classification of certain securities issued by government sponsored agencies. In March 2022, we transferred $357.5 million of these securities from available-for-sale to held-to-maturity at fair value. We intend and have the ability to hold these securities to maturity. The net unrealized pre-tax loss of $14.8 million that remained in accumulated other comprehensive loss is accreted over the remaining lives of the securities.

The amortized cost and fair value of investment debt securities by contractual maturity at June 30, 2022 and December 31, 2021 are shown below. Expected maturities may differ from contractual maturities if the issuers of the securities have the right to call or prepay obligations with or without call or prepayment penalties.

As of June 30, 2022, the investment portfolio included 18 investment securities that had been in a continuous loss position for twelve months or more and 391 investment securities that had been in a loss position for less than twelve months.

Securities issued by government-sponsored agencies, such as FNMA and FHLMC, usually have implicit credit support by the U.S. federal government. However, since 2008, FNMA and FHLMC have been under government conservatorship and, therefore, contractual cash flows for these investments carry explicit guarantees by the U.S. federal government. Securities issued by the SBA and GNMA have explicit credit guarantees by the U.S. federal government, which protects us from credit losses on the contractual cash flows of the securities.

Our investment in obligations of state and political subdivisions bonds are deemed credit worthy after our comprehensive analysis of the issuers' latest financial information, credit ratings by major credit agencies, and/or credit enhancements.

At June 30, 2022, management determined that it did not intend to sell any investment securities with unrealized losses, and it is more likely than not that we will not be required to sell securities with unrealized losses before recovery of their amortized cost. No allowances for credit losses have been recognized on available-for-sale securities in an unrealized loss position, as management does not believe any of the securities are impaired due to reasons of credit quality at June 30, 2022.

Non-Marketable Securities Included in Other Assets

FHLB Capital Stock

As a member of the FHLB, we are required to maintain a minimum investment in FHLB capital stock determined by the Board of Directors of the FHLB. The minimum investment requirements can increase in the event we increase our total asset size or borrowings with the FHLB. Shares cannot be purchased or sold except between the FHLB and its members at the $100 per share par value. We held $16.7 million of FHLB stock included in other assets on the consolidated statements of condition at both June 30, 2022 and December 31, 2021. The carrying amounts of

these investments are reasonable estimates of fair value because the securities are restricted to member banks and they do not have a readily determinable market value. Based on our analysis of FHLB's financial condition and certain qualitative factors, we determined that the FHLB stock was not impaired at June 30, 2022 and December 31, 2021. On July 28, 2022, FHLB announced a cash dividend for the first quarter of 2022 at an annualized dividend rate of 6.00% to be distributed in mid-August 2022. Cash dividends paid on FHLB capital stock are recorded as non-interest income.

VISA Inc. Class B Common Stock

As a member bank of Visa U.S.A., we held 10,439 shares of Visa Inc. Class B common stock at June 30, 2022 and December 31, 2021. These shares have a carrying value of zero and are restricted from resale to non-member banks of Visa U.S.A. until their conversion into Class A (voting) shares upon the termination of Visa Inc.'s Covered Litigation escrow account. Because of the restriction and the uncertainty on the conversion rate to Class A shares, these shares lack a readily determinable fair value. When converting this Class B common stock to Class A common stock based on the estimated conversion rate of 1.6059 and 1.6181 at June 30, 2022 and December 31, 2021, and the closing stock price of Class A shares at those respective dates, the converted value of our shares of Class B common stock would have been $3.3 million and $3.7 million at June 30, 2022 and December 31, 2021, respectively. The conversion rate is subject to further adjustment upon the final settlement of the covered litigation against Visa Inc. and its member banks. As such, the fair value of these Class B shares can differ significantly from their converted values. For further information, refer to Note 8, Commitments and Contingencies.

Low Income Housing Tax Credits

We invest in low-income housing tax credit funds as a limited partner, which totaled $2.7 million and $3.0 million recorded in other assets as of June 30, 2022 and December 31, 2021, respectively. In the first six months of 2022, we recognized $317 thousand of low-income housing tax credits and other tax benefits, offset by $267 thousand of amortization expense of low-income housing tax credit investment, as a component of income tax expense. As of June 30, 2022, our unfunded commitments for these low-income housing tax credit funds totaled $392 thousand. We did not recognize any impairment losses on these low-income housing tax credit investments during the first six months of 2022 or 2021, as the value of the future tax benefits exceeds the carrying value of the investments.
