InterFirst Bankcorp (1993), Colonial Central Savings Bank (1994) and Fidelity Savings Bank (1996). Effective May 1, 1995, Standard Federal Bank became a wholly owned subsidiary of Standard Federal Bancorporation, Inc., a unitary thrift holding company. Purchase by ABN AMRO On November 21, 1996, ABN AMRO reached an agreement to purchase Standard Federal Bancorporation Inc for $1.9 billion; the acquisition completed on May 1, 1997. In 1996, Standard Federal was the largest savings bank in the Midwest, and the fourth largest bank in the State of Michigan. At December 31, 1996, Standard Federal's total assets amounted to $15.7 billion, with total deposits of $11.0 billion, loans serviced for others of $10.5 billion and stockholders' equity of $956.8 million. In 2001, Standard Federal Bank absorbed ABN AMRO's newly acquired Michigan National Bank. The merged bank adopted the acquired bank's national bank charter and the bank became Standard Federal Bank N.A., closing 59 overlapping branch offices and making Standard Federal Michigan's largest bank by the number of branch offices. Rebranding to LaSalle Bank On September 12, 2005, ABN AMRO and its American subsidiary LaSalle Bank Corporation officially changed the name of Standard Federal Bank N.A. to LaSalle Bank Midwest N.A. in what it called a "brand consolidation" instead of a merger with Chicago-based LaSalle Bank N.A. to pool the two banks' marketing resources. Sale to Bank of America On April 23, 2007, ABN AMRO announced the sale of LaSalle Bank Corporation to Bank of America for $21 billion, and a net sale of $16 billion after the return of $5 billion in excess capital. A consortium led by Royal Bank of Scotland filed a legal challenge to the deal as ABN AMRO did not seek higher bids from other potential purchasers, however, the Dutch Supreme Court ultimately approved the sale. Bank of America closed the purchase on October 1, 2007, and LaSalle Bank Midwest began doing business under the Bank of America brand on May 5, 2008.
