WASHINGTON (AP) - Regulators on Friday shut down small banks in Maryland and Minnesota, pushing to 83 the number of bank failures this year amid the soured economy and rising loan defaults.

The Federal Deposit Insurance Corp. took over Baltimore-based Bradford Bank, with about $452 million in assets and $383 million in deposits. It also seized Mainstreet Bank, based in Forest Lake, Minn., with assets of $459 million and deposits of $434 million.

Manufacturers and Traders Trust Co., based in Buffalo, N.Y., has agreed to assume the deposits and assets of Bradford Bank. The nine branches of Bradford Bank will reopen Saturday as offices of M&T.

Central Bank, based in Stillwater, Minn., is assuming the deposits and assets of Mainstreet Bank, whose eight branches will reopen Saturday as offices of Central Bank.

In addition, the FDIC agreed to share with M&T losses on about $338 million of Bradford Bank's loans and other assets, and struck a similar agreement with Central Bank for around $268 million of Mainstreet Bank's.

The failure of Bradford Bank is expected to cost the deposit insurance fund an estimated $97 million; that of Mainstreet Bank about $95 million, the FDIC said.

The number of banks on the FDIC's confidential "problem list" jumped to 416 at the end of June from 305 in the first quarter.
