ZURICH, Feb 4 (Reuters) - UBS said on Tuesday several class action lawsuits relating to a probe into possible manipulation of the foreign exchange market had been filed against it and other banks.
The actions, filed since November, allege collusion by the defendants, and assert claims under antitrust laws and for unjust enrichment, the Swiss bank said in its quarterly report.
UBS said it had not yet filed a responsive pleading to the actions.
In slides released alongside its quarterly report, the Swiss bank said it expected elevated charges for litigation, regulatory and similar matters through 2014.
UBS is one of a number of banks cooperating with a global investigation in to possible rigging in the $5.3 trillion-a-day foreign exchange market.
