[1] | On August 12, 2005, we completed a private placement of $35.0 million of 6.38% Cumulative Trust Preferred Securities. The trust preferred securities were offered by Stifel Financial Capital Trust II (the “Trust II”), a non-consolidated wholly owned subsidiary of our company. The trust preferred securities mature on September 30, 2035, but may be redeemed by our company, and in turn, the Trust II would call the debenture beginning September 30, 2010. The Trust II requires quarterly distributions of interest to the holders of the trust preferred securities. Distributions are payable at a floating interest rate equal to three-month LIBOR plus 1.70% per annum. During 2016, we extinguished $15.0 million of the Trust II debentures.
