i worry more about tail risk at subs than tail risks in their marketable securities - like Apple. I don't think you can own something like BHE and not have the occasional - pardon the pun - flare up. Likewise, you can't own a re-insurer and not have some really bad hurricane years. While not fun to endure, I think BRK takes on water over the gunnels, but the ship doesn't sink. The earnings power is just so large. If there's anyone who would increase capex to fix the issues - it's BRK. We'll see what they do at Pacific Corp. Certainly no expert here - but there are now utilities installing fire prevention wrapped utility poles and using a gizmo on the pole that de-energizes the line if something touch it - to prevent fires. Burying lines is just too expensive.
