Ledecky And Malkin Only Purchased 10% of the Islanders?

According to the New York Post, Jonathan Ledecky and Scott Malkin who purchased a "substantial minority interest" in the Islanders last month only actually purchased 10% of the team.  The article states, "Ledecky's group is buying only a 10% stake in the Islanders, and will need to line up additional funding or investors to buy out Wang, according to sources."

This is slightly concerning to me, however, this would at least partially explain the two year wait for them to become majority owners.
