Zurich - Shares in UBS fell Tuesday, hitting a new low on the Zurich exchange, as Switzerland's largest bank said it would fight to keep client information protected.
The stock hit 9.35 Swiss francs during trading, a record low, but did recover slightly to close at 9.85, down 1.5 per cent on the day.
A US judge on Monday gave UBS until April 30 to file a response to a summons against it by authorities there, demanding that the bank hand over some 52,000 names of US clients holding assets in Switzerland. The judge scheduled a trial for July 13.
