If it makes you feel any better, my guess is 60% Class 18, 40% Class 12, and zero % Class 21. But, if I'm wrong, and the conversion is correct, WAMUQ is up in smoke. My first guess was .005. The last numbers are those opined by DIME class counsel.
But regardless if Class 18 applies to DIME, the commons and preferreds are still subject to a two step death trap, which most don't understand, even though it is spelled out in the DS.
