Schedule of gross unrealized loss position of investments

The following tables summarize the fair value of securities held-to-maturity and securities available-for-sale at June 30, 2022 and December 31, 2021 and the corresponding amounts of gross unrealized losses. Management uses the valuations as of month-end in determining when securities are in an unrealized loss position. Therefore, a security’s market value could have exceeded its amortized cost on other days during the prior twelve-month period.
