On June 27, 2016, BOK Financial Corporation (the "Company") completed the issuance and sale of $150 million aggregate principal amount of its 5.375% Subordinated Notes due 2056 (the "Notes"). The Notes were offered pursuant to the prospectus supplement dated June 20, 2016, constituting part of the Registration Statement on Form S-3 (No. 333-212120) (the "Registration Statement")  that became effective when filed with the Securities and Exchange Commission on June 20, 2016.
The Notes were issued under the Subordinated Debt Indenture, dated as of June 27, 2016 (the "Indenture"), between the Company and U.S. Bank National Association, as Trustee. The Notes will bear interest at the rate of 5.375% per annum, with interest payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year, commencing September 30, 2016. The Notes will mature on June 30, 2056. On or after June 30, 2021, the Company will have the option to redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued interest. The Company's ability to exercise such redemption option is subject to the prior approval of the Board of Governors of the Federal Reserve System.
The Company's obligation to make payments of principal and interest on the Notes is subordinate and junior in right of payment to all of its "Senior Debt" (as defined in the Indenture).
