It looks like they also distribute capital gains on the long ETFs. This adds to the dividend for the total distribution. You can see the exact amounts here: http://www.proshares.com/funds/distributions
For in the future, here is the proshares distributions..http://www.proshares.com/funds/distributions For DDM for example you see: .36 for the normal dividiend which everyone is familiar with... The one you been getting every quarter... Then you have for this qtr: 3.44 for short term capital gaines and .11 for long term capital gaines Bring the total to around: $3.91 total dividend this qtr
Also notice that you will take the price hit today but won't get credit for the distribution until 12/28.
