QUANTUMONLINE.COM SECURITY DESCRIPTION:  BOK Financial Corp., 5.375% Subordinated Notes due 2056, issued in $25 denominations, redeemable at the issuer's option on or after 6/30/2021 at $25 per note plus accrued and unpaid interest, and maturing 6/30/2056.

Distributions paid by these debt securities are interest and as such are NOT eligible for the preferential 15% to 20% tax rate on dividends and are also NOT eligible for the dividend received deduction for corporate holders. Units are expected to trade flat, which means accrued interest will be reflected in the trading price and the purchasers will not pay and the sellers will not receive any accrued and unpaid interest. This security was rated as A3 by Moody’s and BBB by S&P at the date of its IPO. The Notes are unsecured, subordinated obligations of the company and will rank equally with all existing and future unsecured, subordinated indebtedness of the company.
