1) The mentioned "Series A redemption" is the redemption of KKR's(!!!) Series A and NOT WMIH's Series A. Totally unrelated to WMIH!!!
2) The "new" WMIH's Series B were not delisted, it is about the "old" Series B (which was in effect until 01/05/2018) with a conversion price of 1.75 - 2.25 (the number of commons they convert to (=342,857,143) in the document proves this).
The "new" Series B (in effect since 01/05/2018 have a fixed conversion price of $1.35 and convert to 444,444,444 common shares. They are NOT MENTIONED and NOT AFFECTED by this filing.
