There’s many complexities with share holdings, and I don’t think it’s much to worry about. To put into perspective I understand in addition to the $3billionish in shares that Knighthead Capital Management hold there is around $10billion or so in cash/undisclosed assets. There’s also Knighthead Annuity which is performing very well.
When I have some time I do intend to look into it a bit more, but it’s nothing to be concerned about.
