Long-term borrowings: Our long-term borrowings of $730,000 and $735,000 at March 31, 2019 and December 31, 2018, respectively, consisted of advances from the Federal Home Loan Bank (“FHLB”) and structured repurchase agreements with unaffiliated institutions.

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 March 31, 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:
