Short-Term Borrowings

The Company has from time-to-time entered into borrowing agreements with the FHLB and FRB. Borrowings under these agreements are collateralized by stock in the FHLB, qualifying first and second mortgage residential loans, investment securities, and commercial real estate loans under a blanket-floating lien.

As of December 31, 2020, there were no outstanding Short-Term borrowings. At December 31, 2019, there was $700.0 million in outstanding Short-Term FHLB advances. For the years ended December 31, 2020 and 2019, the average balance for short-term borrowings was $745.9 million and $538.6 million, respectively. There were no short-term borrowings at December 31, 2020, but the year-to-date weighted average cost for the year ended December 31, 2020 was 0.63%. The weighted average cost of the short-term borrowing at period end December 31, 2019 was 1.73% and the weighted average cost year to date for the year ended December 31, 2019 was 2.35%. Net eligible loans of the Company pledged via a blanket lien to the FHLB for advances and letters of credit at December 31, 2020, were approximately $3.6 billion and investment securities pledged were approximately $346.6 million. This allows the Company a total borrowing capacity at the FHLB of approximately $2.8 billion. After accounting for letters of credit totaling $12.2 million, the Company had unused net credit available with the FHLB in the amount of approximately $2.8 billion at December 31, 2020. The Company also has a total borrowing capacity at the FRB of $1.2 billion at December 31, 2020 secured by a blanket lien on $2.0 billion in net eligible loans of the Company. The Company had no outstanding borrowings with the FRB at December 31, 2020.

During the fourth quarter of 2020, we paid-off early our FHLB advances of $700.0 million and terminated the interest rate swaps related to these advances at a cost of $38.8 million reflected in noninterest expense in the Consolidated Statements of Income.

Junior Subordinated Debt

The obligations of the Company with respect to the issuance of the capital securities constitute a full and unconditional guarantee by the Company of the trusts’ obligations with respect to the capital securities. Subject to certain exceptions and limitations, the Company may elect from time to time to defer interest payments on the junior subordinated debt securities, which would result in a deferral of distribution payments on the related capital securities.

All of the Company’s junior subordinated debt is callable after five years from issuance. Therefore, all of the junior subordinated debt is callable at December 31, 2020.

As of December 31, 2020, the sole assets of the trusts were an aggregate of $144.3 million of the Company’s junior subordinated debt securities with like maturities and like interest rates to the trust preferred securities.

As of December 31, 2020, the Company recorded a $144.3 million liability for the junior subordinated debt securities, net of a $14.1 million discount recorded on Southeastern Bank Financial Statutory Trust I and II, Citizens South Banking Corporation Statutory Trust I, Community Capital Statutory Trust I, FCRV Statutory Trust I, Provident Community Bancshares Capital Trust I and II, CenterState Banks of Florida Statutory Trust I, Federal Trust Statutory Trust I, Gulfstream Bancshares Capital Trust II, Homestead Statutory Trust I, BSA Financial Statutory Trust I, and MRCB Statutory Trust II. The Company, as issuer, can call any of these subordinated debt securities without penalty. If the Company were to call the securities, the amount paid to the holders would be $158.4 million and the Company would fully amortize any remaining discount into interest expense. The remaining discount is being amortized over either a one and one-half year period, a five-year period or a fourteen and one-half year period depending on the merger acquired.

As of December 31, 2020, and 2019, there was $144.3 million (net of discount of $14.1 million) and $115.8 million (net of discount of $2.7 million), respectively, in junior subordinated debt. The weighted average cost of the junior subordinated debt at period end December 31, 2020 was 2.05% and the weighted average cost year to date for the year ended December 31, 2020 of 2.51%. This does not take into account the discount. If the discount were taken into account, the weighted average cost year to date would be 3.56%. This compares to a weighted average cost of the junior subordinated debt at period end December 31, 2019 of 3.60% and the weighted average cost year to date for the year ended December 31, 2019 of 4.20%. If the discount were taken into account, the weighted average cost year to date would be 4.88% in 2019.

Pursuant to the Basel III rules adopted by the bank regulatory agencies in July 2013, financial institutions with less than $15 billion in total assets may continue to include their trust preferred securities issued prior to May 19, 2010 in Tier 1 capital, but cannot include in Tier 1 capital any trust preferred securities issued after such date. A financial institution may continue to include its trust preferred securities in Tier 1 capital if it exceeds $15 billion in total assets through organic growth, but if it exceeds $15 billion in total assets through an acquisition or enters into an acquisition after exceeding $15 billion in total assets through organic growth, then the trust preferred securities would no longer be included in Tier 1 capital. Therefore, upon closing on the merger with CSFL in 2020, total trust preferred securities of $158.4 million of the combined Company would no longer be included in Tier 1 capital. Following the merger, these trust preferred securities are now only included in Tier 2 capital for regulatory capital purposes.

Subordinated Debt and Notes

As of December 31, 2020, the Company recorded a $245.9 million liability for the subordinated debt, which was net of $3.1 million in debt issuance costs recorded on the CenterState subordinated debt issuance of $200.0 million. The remaining balance of the debt issuance costs are being amortized over an eight and one-half year period. There was no subordinated debt outstanding at December 31, 2019 as all this debt was acquired in the merger with CSFL in June 2020.

The weighted average cost of the subordinated debt at period end December 31, 2020 was 5.78% and the weighted average cost year to date for the year ended December 31, 2020 of 5.69%. This does not take into account the amortization of the debt issuance costs. If the debt issuance costs were taken into account, the weighted average cost year to date would be 5.93%.

Qualifying subordinated debt can be included in Tier 2 capital for regulatory capital purposes. Of our subordinated debt, the amounts for the National Bank of Commerce, Landmark Bancshares and CenterState Bank Corporation totaling $238.0 million qualify for Tier 2 capital. The subordinated notes for Residential Warranty Corp. and Messiah College totaling $11.0 million do not qualify for Tier 2 capital purposes.

Line of Credit

On November 15, 2020, the Company entered into an amendment to its Credit Agreement (the “Agreement”) with U.S. Bank National Association (the “Lender”). The Agreement provides for a $100 million unsecured line of credit by the Lender to the Company. The maturity date of the Agreement is November 15, 2021, provided that the Agreement may be extended subject to the approval of the Lender. Borrowings by the Company under the Agreement will bear interest at a rate per annum equal to 2.00% plus the greater of 0.00% or one-month LIBOR. As of December 31, 2020 and 2019, and there was no outstanding balance associated with the line of credit.
