Bank of Wausau was shut down by Wisconsin regulators Friday.
Nicolet National Bank in Green Bay agreed to buy $29.9 million of the failed bank's $43.6 million assets from the Federal Deposit Insurance Corp., which acted as receiver. The $664 million-asset Nicolet also agreed to assume Bank of Wausau's $40.7 million in deposits.
The FDIC said it would retain the rest of the assets for disposition later. The failure is expected to cost the Deposit Insurance Fund $13.5 million.
Eighteen U.S. banks have failed this year. Two of them were in Wisconsin; the other was Banks of Wisconsin in Kenosha on May 31.
