IMO we could see two separate distributions from the WMILT, from the bankruptcy estate via LTI's and bankruptcy remote Safe Harbor assets via ???, not sure.
Bankruptcy estate: We could see about $30M distributed to our markers @ a 75%/25% ratio. This would give Commons 25% X $30M = $7.5M. This would give the 1.2B Commons that released ~$0.0063/share ie $7.5M/1.2B shares. You would receive 400K X $0.0063/share = $2520.
Safe Harbor assets: My expectations are $2B-$10B return to our markers. Using a median return of $5B Commons 25% share would be $5B X 25% = $1.25B. The return per released Common share will be $1.25B/1.2B shares = $1.04/share. $400K X $1.04 = $416000 for your holdings.
If more or less comes back calculate the return based on the $5B figure above. Hopefully our theories are at least somewhat correct
