I think these moves are meant to prepare Abel for the CEO role. Buffett has said that Greg will be responsible for capital allocation. If Buffett were in Greg’s position, he wouldn’t want large legacy positions from a prior CEO hanging over his head. Historically, when Berkshire acquires insurance businesses, Buffett almost always liquidates the existing investment portfolio and starts fresh. He appears to be applying the same principle here, clearing out outsized positions so Abel can step into the role with a relatively clean slate.
