NEW YORK (TheStreet) -- UBS (UBS) - Get Report has reportedly laid off 200 people at its wealth-management division in the U.S.

Under fire from the U.S. government over the

alleged tax-evasion tactics

used by the big Swiss bank and its clients, UBS had already announced 8,700 job cuts in April after posting steep losses amid the financial crisis.

The fresh layoffs -- reported by

Reuters

, which cited anonymous sources -- are said to be among junior and new financial advisors.

In the

Reuters

report, several analysts speculated that UBS's once-vaunted wealth-management business may be suffering in the wake of UBS's settlement with the IRS, under which the bank agreed to hand over the names of 4,450 account holders to authorities.

One UBS wealth manager has already been

sentenced to jail time

: Bradley Birkenfeld, a whistleblower who provided some of the key material that aided the U.S. in its tax-fraud case against UBS.

UBS shares were up slightly in the early going Wednesday, trading at $19, up 14 cents from the previous close.
