Long-term borrowings: Our long-term borrowings of $722,000 and $735,000 at September 30, 2019 and December 31, 2018, respectively, consisted of advances from the Federal Home Loan Bank (“FHLB”). These FHLB advances are collateralized primarily by similar amounts of residential mortgage loans, certain commercial loans, mortgage backed securities and securities of U. S. Government agencies and corporations.

Our long term FHLB borrowings bear both fixed and variable rates and mature in varying amounts through the year 2026.

The average interest rate paid on long-term borrowings for the nine month period ended September 30, 2019 was 5.34% compared to 4.24% for the first nine months of 2018.

Subordinated debentures owed to unconsolidated subsidiary trusts: We have three statutory business trusts that were formed for the purpose of issuing mandatorily redeemable securities (the “capital securities”) for which we are obligated to third party investors and investing the proceeds from the sale of the capital securities in our junior subordinated debentures (the “debentures”). The debentures held by the trusts are their sole assets. Our subordinated debentures totaled $19.6 million at September 30, 2019 and December 31, 2018.

The capital securities held by SFG Capital Trust I, SFG Capital Trust II, and SFG Capital Trust III qualify as Tier 1 capital under Federal Reserve Board guidelines. In accordance with these Guidelines, trust preferred securities generally are limited to 25% of Tier 1 capital elements, net of goodwill. The amount of trust preferred securities and certain other elements in excess of the limit can be included in Tier 2 capital.

A summary of the maturities of all long-term borrowings and subordinated debentures for the next five years and thereafter is as follows:
