a 1099 would certainly be a tax issue like the original poster was asking. I don't own this, but UBTI is the main issue in an IRA with MLP's. Hard to imagine that and ETF of MLP's does not have an IRA tax event. The UBTI has to go somewhere.
PBR will move higher from here and fast. Just think back to the Brazilian elections when it "appeared" that Dilma would not get re-elected. PBR really took off. Alas, it was not to be, but you can see PBR's move today makes sense in light of the impeachment news.
