my TD ameritrade says 10.72 while yahoo has the 17%. I have found TDA to be more accurate on yields than yahoo. Also go to Yahoo fianance, enter ure symbol, and click on historical prices and then click on dividends. It is paid quarterly, I just got paid 6/30. I got paid 11.43 (ordinary divident) and 10.24 on a total of 800 shares. The 10.24 was referred to as a substitute payment and to be honest, I dont know what that means.
good luck, hope this helped!
