iPrelude -- it's convoluted to do the math back to the three types of former equity. What the math is about is the initial WMIH shares. Each of the three types of former equity had different ratios of conversion into WMIH shares, and therefore would have different ratios of the disputed-equity distribution.
For the purposes of the calculations -- forget the former equity (Escrow) share counts. Do the math only on the original WMIH shares you received.
