Well, I’m glad you asked.
I started the day buy tucking away a few Merchants Trust (MRCH) into my High Yield Portfolio (HYP). Over the last 3 years Merchants have paid out dividends representing a yield of 7.9% (2009), 6.8% (2010) and 5.6% (2011) so they seemed like a perfect addition to the HYP. They appear to pay out dividends quarterly. I managed to buy at 373.6p per share (including Stamp Duty).
Most of the other share purchases made today were to reduce the average buying price of already held shares.
