Specifically I'm looking for information regarding SCU, which according to some sources seems to be a preferred share of SCG, but I can't find any information regarding its call date, convertibility, whether or not it's cumulative.
This site has the best information I could find, other than a Bloomberg terminal:
QUANTUMONLINE.COM SECURITY DESCRIPTION: SCANA Corp., 2009 Series A, 7.70% Enhanced Junior Subordinated Notes, issued in $25 denominations, redeemable at the issuer's option on or after 1/30/2015 at $25 per share plus accrued and unpaid interest, and maturing 1/30/2065 which may be extended to 1/30/2080. Interest distributions of 7.70% ($1.925) per annum are paid quarterly on 1/30, 4/30, 7/30 & 10/30 to holders of record on the record date which is the business day prior to the payment date (NOTE: the ex-dividend date is at least 2 business days prior to the record date). 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. The Notes are unsecured and subordinated obligations of the company and will rank equally with all existing and future unsecured and subordinated indebtedness of the company.
