Per a Bloomberg story on March 21:

> Dealers including JPMorgan Chase & Co. and Morgan Stanley are willing to buy risky Credit Suisse debt known as additional tier 1 bonds, or AT1s, for somewhere around 2 cents on the dollar and sell somewhere around 5 cents as of early afternoon on Monday in New York, according to the people. The Swiss bank said on Sunday that the bonds would be written down to zero as a condition of the rescue of the bank.

Resolves YES if bondholders receive 5 cents on the dollar or greater for their bonds, NO otherwise.

This may involve litigation, so an answer may not be known for some time.
