At December 31, 2021, there were 80 securities AFS in an unrealized loss position. Management assessed each investment security with unrealized losses for credit loss and determined substantially all unrealized losses on these securities were due to credit spreads and interest rates versus credit loss. As part of that assessment, management evaluated and concluded that it is more-likely-than-not that the Company will not be required and does not intend to sell any of the securities prior to recovery of the amortized cost. At December 31, 2021, there was no ACL for debt securities AFS.

The amortized cost and fair value of debt securities by contractual maturity are shown below. Certain securities have call features that allow the issuer to call the security prior to maturity. Expected maturities may differ from contractual maturities in mortgage-backed securities ("MBS") because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Therefore, MBS are not included in the maturity categories in the following maturity summary. The expected maturities of certain SBA securities may differ from contractual maturities because the borrowers may have the right to prepay the obligation. However, certain prepayment penalties may apply.

Equity Securities

The Company held $9.9 million at December 31, 2021 and $12.7 million at September 30, 2021 in marketable equity securities. The Company recognized $2.3 million in unrealized loss in an investee during the three months ended December 31, 2021. All other marketable equity securities and related activity were insignificant for the three months ended December 31, 2021 and 2020. No marketable securities were sold during the first quarter of fiscal year 2022.

Non-marketable equity securities with a readily determinable fair value totaled $5.6 million at December 31, 2021 and $4.6 million at September 30, 2021. The Company recognized $0.3 million in unrealized losses and $0.1 million in unrealized gains during the three months ended December 31, 2021 and 2020, respectively. No such securities were sold during the first quarter of fiscal year 2022.

Non-marketable equity securities without readily determinable fair value totaled $15.9 million at December 31, 2021 and $16.0 million at September 30, 2021. There was one security sold during the first quarter of fiscal year 2022 for a $0.1 million gain.

FRB Stock

The Bank is required by federal law to subscribe to capital stock (divided into shares of $100 each) as a member of the FRB of Minneapolis with an amount equal to six per centum of the paid-up capital stock and surplus. One-half of the subscription is paid at time of application, and one-half is subject to call of the Board of Governors of the Federal Reserve System. FRB of Minneapolis stock held by the Bank totaled $19.7 million at December 31, 2021 and September 30, 2021. These equity securities are 'restricted' in that they can only be owned by member banks.

FHLB Stock

The Company's borrowings from the FHLB are secured by specific investment securities. Such advances can be made pursuant to several different credit programs, each of which has its own interest rate and range of maturities.

The investments in the FHLB stock are required investments related to the Company's membership in and current borrowings from the FHLB of Des Moines. The investments in the FHLB of Des Moines could be adversely impacted by the financial operations of the FHLB and actions of their regulator, the Federal Housing Finance Agency.

The FHLB stock is carried at cost since it is generally redeemable at par value. The carrying value of the stock held at the FHLB was $8.7 million at December 31, 2021 and $8.7 million at September 30, 2021.

These equity securities are ‘restricted’ in that they can only be sold back to the respective institution from which they were acquired or another member institution at par. Therefore, FRB and FHLB stocks are less liquid than other marketable equity securities, and the fair value approximates cost.

Equity Security Impairment

The Company evaluates impairment for investments held at cost on at least an annual basis based on the ultimate recoverability of the par value. All other equity investments, including those under the equity method, are reviewed for other-than-temporary impairment on at least a quarterly basis. The Company recognized no impairment for such investments for the three months ended December 31, 2021.
