Very good Question and the answer appears to be that YES, we are royally screwed. REC (A Rydex Double short) paid an 87% Short term distribution recently. If anything like that happens here..you can imagine how screwed we will be.
Why don't you just go to the proshares website and find out for yourself that any distribution will be insignificant. SRS distributions are quarterly and have been .06 - .73 cents per shares. Look at the historical spreadsheet on proshares' website.
