Last December and this past may, RSO had huge opportunities to buy back debt. I doubt they have similar opportunities now. J. Cohen did say that they were taking the offensive (as opposed to defensive) position -- to make new loans. RSO already had free cash, and I doubt they need additional immediate cash.
Furthermore, RSO knows that they are getting far more from their DRIP.
Of course, there's no guarantee that there's no offering in the works, but I think the odds are against it -- at least for this December. JMHO
