Why are they saying it wasn't a CET1 event? If they still had/have high capital ratios then they should remain viable. Does this mean banks with lower capital ratios that CS had are less viable (fortunately the CET1 ratio of UBS was 14.2% vs CS 14.1% - so they are much safer)? Ultimately the rules were followed, because in addition to specific capital thresholds triggering events, they can be zeroed whenever they want for any reason.
