Subordinated Notes

On October 28, 2020, we issued $150 million of Subordinated Debt (the "Notes") with a maturity date of November 1, 2030. The Notes bear interest at a fixed rate of 4.125 percent through October 31, 2025, and a variable rate tied to SOFR thereafter until maturity. We have the option to redeem all or a part of the Notes beginning on November 1, 2025, and on any subsequent interest payment date. The Notes qualify as Tier 2 capital for regulatory purposes.

Trust Preferred Securities

    We sponsor nine trust subsidiaries, which issued preferred stock to third party investors. We issued junior subordinated debt securities to those trusts, which we have included in long-term debt. The junior subordinated debt securities are the sole

assets of those trusts. The trust preferred securities are callable by us at any time. Interest is payable quarterly; however, we may defer interest payments for up to 20 quarters without default or penalty. As of March 31, 2022, we had no deferred interest.
