Whilst it is unlikely to bankrupt them, it does depend on:
a) How many child abuse victims there are
b) How many come forward and sue
If there were 1,000s that came forward, and were awarded Candace Conti type pay outs, then yes it could do. Lets say 1,000 cases get awarded $10M each. Then that's $10BN.
I don't think the WT has that much stashed to one side.
