Preferred shareholders stand in front of the line.
Preferred stock has a claim on liquidation proceeds of a stock corporation, equivalent to its par or liquidation value. This claim is senior to that of common stock, which has only a residual claim.
As to conversion, that's what "poison pills" are. In the event of liquidation all preferreds are converted prior to liquidation.
That's the way things are, as a long I wish it wasn't.
Until I see it in a "legal filing" as an exception to the norm, I'm assuming it's the case here as well.
