Note 3: Investment Securities
Effective January 1, 2020, the Company adopted FASB ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Upon adoption of the ASU the Company recorded allowance for credit losses for debt securities held to maturity of $16 thousand. During the fourth quarter ended December 31, 2020, the Company recorded $7 thousand of reversal of provision for credit loss on debt securities held to maturity, resulting in the balance of $9 thousand allowance for credit losses for debt securities held to maturity.
An analysis of the amortized cost and fair value by major categories of debt securities available for sale, which are carried at fair value with net unrealized gains (losses) reported on an after-tax basis as a component of cumulative other comprehensive income, and debt securities held to maturity, which are carried at amortized cost, before allowance for credit losses of $9 thousand, follows:
The amortized cost and fair value of debt securities by contractual maturity are shown in the following tables at the dates indicated:
Expected maturities of mortgage-related securities can differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may affect the yield on the carrying value of mortgage-related securities. At March 31, 2021 and December 31, 2020, the Company had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.
An analysis of the gross unrealized losses of the debt securities available for sale portfolio follows:
An analysis of gross unrecognized losses of the debt securities held to maturity portfolio follows:
Based upon the most recent evaluation, the unrealized losses on the Company’s debt securities available for sale were most likely caused by market conditions for these types of investments, particularly changes in risk-free interest rates and/or market bid-ask spreads. The Company does not intend to sell any debt securities available for sale and has concluded that it is more likely than not that it will not be required to sell the debt securities prior to recovery of the amortized cost basis. Therefore, the Company does consider these debt securities to have credit related loss as of March 31, 2021.
The fair values of debt securities available for sale could decline in the future if the general economy deteriorates, inflation increases, credit ratings decline, the issuer’s financial condition deteriorates, or the liquidity for debt securities declines. As a result, significant credit loss on debt securities available for sale may occur in the future.
As of March 31, 2021 and December 31, 2020, the Company had debt securities pledged to secure public deposits and short-term borrowed funds of $844,502 thousand and $888,577 thousand, respectively.
An analysis of the gross unrealized losses of the debt securities available for sale portfolio follows:
An analysis of gross unrecognized losses of the debt securities held to maturity portfolio follows:
The Company evaluates debt securities on a quarterly basis including changes in security ratings issued by rating agencies, changes in the financial condition of the issuer, and, for mortgage-backed and asset-backed securities, collateral levels, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a major rating agency. One corporate bond with an amortized cost of $15.0 million and a fair value of $14.98 million at March 31, 2021, is rated below investment grade. The $14.98 million corporate bond was issued by a pharmaceutical company which develops, manufactures and markets generic and branded human pharmaceuticals, as well as active pharmaceutical ingredients, to customers worldwide. The bond matures in July 2021. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities.
The following table presents the activity in the allowance for credit losses for debt securities held to maturity:
Agency mortgage-backed securities were assigned no credit loss allowance due to the perceived backing of government sponsored entities. Municipal securities were evaluated for risk of default based on credit rating and remaining term to maturity using Moody’s risk of default factors; Moody’s loss upon default factors were applied to the assumed defaulted principal amounts to estimate the amount for credit loss allowance.
The following table summarizes the amortized cost of debt securities held to maturity at March 31, 2021, aggregated by credit rating:
There were no debt securities held to maturity on nonaccrual status or past due 30 days or more as of March 31, 2021.
The following table provides information about the amount of interest income earned on investment securities which is fully taxable and which is exempt from federal income tax:
