QUANTUMONLINE.COM SECURITY DESCRIPTION:  Western Alliance Bancorporation, 6.25% Subordinated Debentures due 2056, issued in $25 denominations, redeemable at the issuer's option on or after 7/1/2021 at $25 per note plus accrued and unpaid interest, and maturing 7/1/2056. Interest distributions of 6.25% per annum ($1.5625 per annum or $0.390625 per quarter) will be paid quarterly on 1/1, 4/1, 7/1 & 10/1 to holders of record on the record date that will be 12/15, 3/15, 6/15 & 9/15 respectively (NOTE: the ex-dividend date is one business day prior to the record date). This security is possibly subject to an early call as a result of the occurrence of a tax event, capital event or investment company event (see prospectus for further information). 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 not rated by Moody’s or S&P at the time of its IPO. The Debentures are unsecured, subordinated obligations of the company and will rank equally with all existing and future unsecured, subordinated indebtedness of the company.
