A suggestion for an alternative to ORB. Look at TYG and TPZ. Both are in the Tortoise Family of CEF's. Both pay dividends in the 5.5% range. TPZ pays monthly and we've owned this since early 2010 and are enjoying a 6.99% annual dividend. TYG pays quarterly. TPZ is most conservative with 60% of their assets in quality bonds of utility types and 40% MLP stock in the energy sector. We have oil and gas industry backgrounds, so we comfortable with MLP'S.
We've held on to ORB since 2007 and had a chance to get out at a much higher price than today. Didn't take it. Best of luck to all.
