Junior Subordinated Debentures	Note 8 – Junior Subordinated Debentures On March 2, 2020, the Company redeemed the 7.80% cumulative trust preferred securities issued by Old Second Capital Trust I (“OSBCP”) and related debentures, which totaled $32.6 million. These debentures were originally issued in 2003 for a term of 30 years at 7.80%, and subject to regulatory approval, were able to be called in whole or in part by the Company after June 30, 2008. The Company received regulatory approval to redeem the debentures in early 2020, and notified OSBCP stockholders of the redemption in late January 2020. Cash disbursed for the redemption, including accrued interest on the debentures, totaled $33.0 million, or $10.13 per OSBCP share. The OSBCP redemption was funded by cash on hand and the $20 million term note discussed in Note 7 – Borrowings. Upon redemption of the junior subordinated debentures related to OSBCP in March 2020, the Company recognized the remaining unamortized debt issuance costs of $635,000. The Company issued $25.0 million of cumulative trust preferred securities through a private placement completed by another unconsolidated subsidiary, Old Second Capital Trust II, in April 2007. These trust preferred securities also mature in 30 years, but subject to the aforementioned regulatory approval, can be called in whole or in part on a quarterly basis commencing June 15, 2017. The quarterly cash distributions on the securities were fixed at 6.77% through June 15, 2017, and float at 150 basis points over three-month LIBOR thereafter. Upon conversion to a floating rate, a cash flow hedge was initiated which resulted in the total interest rate paid on the debt of 4.40% for the quarter ended September 30, 2020, compared to the rate paid for the quarter ended September 30, 2019, of 4.40%. The Company issued a new $25.8 million subordinated debenture to Old Second Capital Trust II in return for the aggregate net proceeds of this trust preferred offering. The interest rate and payment frequency on the debenture are equivalent to the cash distribution basis on the trust preferred securities. The junior subordinated debentures issued by the Company are disclosed on the Consolidated Balance Sheet, and the related interest expense for each issuance is included in the Consolidated Statements of Income. As of September 30, 2020, and December 31, 2019, the remaining unamortized debt issuance costs related to the junior subordinated debentures were $1,000 and $644,000 respectively, and are included as a reduction to the balance of the junior subordinated debentures on the Consolidated Balance Sheet. The remaining deferred issuance costs on the junior subordinated debentures related to the issuance of Old Second Capital Trust II will be amortized to interest expense over the remainder of the 30-year term of the notes and are included in the Consolidated Statements of Income.
