I am not sure you need to know all this fronting business to get your shares converted. I know zilch and I had no problem getting my shares converted . And from your revealation here, it went through a lot faster than you did yours. All you need to do is tell them what you want done to your shares. If you don't know which option to choose, there is no shame in asking.
But from some of the posts here, EDV obviously is doing a lousy job helping people who got their shares stuck in this freaking fronting traffic.
