Restricted Investment In Stock

Restricted investment in stock includes Federal Home Loan Bank (“FHLB”) stock with a carrying cost of $8,495 and $4,003 at June 30, 2022 and December 31, 2021, respectively, and Atlantic Community Bankers Bank (“ACBB”) stock with a carrying cost of $42 at June 30, 2022 and December 31, 2021, respectively, which are included in other assets in the consolidated balance sheets. FHLB and ACBB stock was issued as a requirement to facilitate participation in borrowing and other banking services. The investment in FHLB stock may fluctuate, as it is based on the member bank’s use of FHLB’s services.

These restricted investments are carried at cost and evaluated for other-than-temporary impairment (“OTTI”) quarterly. As of June 30, 2022, there was no OTTI associated with these investments.

The maturity distribution of the fair value, which is the net carrying amount, of the debt securities classified as available-for-sale at June 30, 2022, is summarized as follows:

Securities with a carrying value of $176,683 and $203,580 at June 30, 2022 and December 31, 2021, respectively, were pledged to secure public deposits and certain other deposits as required or permitted by law.

Securities and short-term investment activities are conducted with a diverse group of government entities, corporations and state and local municipalities. The counterparty’s creditworthiness and type of collateral is evaluated on a case-by-case basis. At June 30, 2022 and December 31, 2021, there were no significant concentrations of credit risk from any one issuer, with the exception of U.S. government agencies and sponsored enterprises, that exceeded 10.0 percent of stockholders’ equity.

Management does not consider the unrealized losses on the debt securities, as a result of significantly higher market interest rates, to be OTTI based on historical evidence that indicates the cost of these securities is recoverable within a reasonable period of time in relation to normal cyclical changes in the market rates of interest. Moreover, because there has been no known material change in the credit quality of the issuers or other events or circumstances that may cause a significant adverse impact on the fair value of these securities, and management does not intend to sell these securities and it is unlikely that the Company will be required to sell these securities before recovery of their amortized cost basis, which may be maturity, the Company does not consider the unrealized losses to be OTTI at June 30, 2022. There was no OTTI recognized for the three or six months ended June 30, 2022 and 2021.
