AllianceBernstein plans to sue the Swiss government for $225 million in damages due to the decision to eliminate $17 billion in Credit Suisse debt during UBS's takeover last year.

The asset management firm, which oversees around $800 billion in assets, will join a legal action initiated by law firm Quinn Emanuel Urquhart & Sullivan on behalf of Credit Suisse bondholders. This legal action reflects the dissatisfaction among investors affected by the debt write-off, raising concerns about the treatment of bondholders after the banking crisis.

The case is expected to attract significant attention and could establish a precedent for future legal actions involving government interventions in financial markets.
