The U.S. may have trumped Switzerland in Olympic men’s hockey on Wednesday, but its tax battle with Switzerland continues.

Swiss news agencies reported on Wednesday that the government would ask Zurich-based banking giant UBS to reimburse it for outside legal costs stemming from the bank’s long-running legal dispute with U.S. authorities over allegations of tax evasion by U.S. citizens holding UBS accounts.

A deal to resolve that dispute by releasing the names of 4,450 U.S. citizens with UBS accounts was tentatively struck last August. UBS relied on lawyers from Wachtell, Lipton, Rosen & Katz, Cravath, Swaine & Moore and Florida’s Stearns Weaver Miller Weissler Alhadeff & Sitterson in those negotiations, while the Swiss government retained Pillsbury Winthrop Shaw Pittman international trade practice chair Stephan Becker and Palm Beach, Fla.-based attorney John Dotterrer on the matter. (UBS also paid a $780 million fine and agreed to turn over nearly 300 client names as part of a deferred prosecution agreement it struck with U.S. prosecutors in February 2009.)

According to Swiss news reports, the dispute between U.S. regulators and UBS has so far cost the Swiss government $2.3 million. UBS has agreed to reimburse the government, which hired Becker and Dotterrer to file briefs in federal court in Florida defending the bank, more than $931,000 of that $2.3 million. The Swiss could eventually incur another $34.4 million in costs as a result of helping U.S. authorities track down American tax evaders. (It's unclear at this point how much of those costs relate to legal fees paid to outside lawyers; Becker and Dotterrer did not respond to requests for comment.)
