Sunrise Banks fought to buy American Bank of St. Paul in federal bankruptcy court Tuesday. American Bank's holding company, American Bancorporation, filed Chapter 11 bankruptcy in May after creditors said they were owed $48 million due to missed payments on investor securities. American Bancorporation subsequently auctioned both its subsidiaries, American Bank and community development organization AmeriNational Community Services Inc. (ACS). The auctions generated a $17 million offer from Deerwood Bank for the bank's assets and a $15.2 million offer for ACS from investment firm OSP Group. But Sunrise Banks wants the court to consider its combined bid. Sunrise argues their bid is $100,000 less than the winning bids, but would be cheaper than two separate deals and more likely to win approval from regulators.
