It's incomprehensible that a company can be worth paying $19B, and then you immediately discard 40%.
Cutting 10% risks leaving a company in crisis. Unless you are closing an isolated factory, cutting 40% leaves a company non-functional.
Companies are notoriously bad at figuring out what is 'fat' when cutting 5%. They'll cut a guy putting in 6 hour days on the off-season, then be short of people at the end of the quarter. There isn't any way that a 40% cut can be done wisely.
