From http://www.horizonsetfs.com/horizons/media/pdfs/prospectus/Benchmark1_Prospectus.pdf : Horizons HXX seeks to replicate, to the extent possible, the performance of the EURO STOXX 50® Futures Roll Index (Total Return), net of expenses.
The EURO STOXX 50® Futures Roll Index (Total Return) is designed to
measure the performance of 50 of the largest companies that are sector leaders
in the Eurozone.

HXX tracks blue-chip companies. It uses swap contracts to get the total return, without actually receiving any dividends. I doubt if HXX plans on paying dividends at all, and GP could be misleading in saying "there have been no distributions to date." There could be advantages like not having to worry about reinvesting, and pesky annual tax filings.
