How are you getting 5? In recent memory, there's only 3: dotcom bubble (2000), GFC (2008), covid (2020). You'd either have to go back in time even more (eg. savings and loan crisis in the 80s/90s), or include regional ones (eg. eurozone crisis) to hit 5.

Are you counting eurozone as 2011? I think it counts enough as American if it caused a downgrade in the USG's credit rating.

Maybe they had strong exposure to Worldcom or Enron?
