Fast-growing Knutson Mortgage Co. has completed its acquisition of 14  FBS Mortgage branches in the West and Midwest. The closing substantially   increases the originations capacity of the Bloomington, Minn.-based lender.   
As other lenders continue to exit the mortgage business, citing thin  profit margins and the high cost of technology investment necessary to   remain competitive, Knutson is taking the opposite course with an expansion   drive.     
  
The acquisition extends the company's reach to Colorado, Montana, South  Dakota, Kansas, and Wyoming. The branches originated $520 million of loans   in 1995, according to FBS.   
"We're committed to building a retail network throughout the heartland  of the United States," said Ray W. Simms, Knutson's president and chief   operating officer, when the acquisition was announced. The branches were   attractive to Knutson because they do not overlap its existing branch   system. Of the states encompassed in the purchase, Wisconsin is the only   one where both companies operated.         
  
Knutson already had branches in Minnesota, Wisconsin, Illinois, Ohio,  Missouri, Oklahoma, Texas, and New England. 
BankAmerica Corp. bought $14 billion of servicing assets from FBS. The  First Bank System unit's retail origination branches were divided between   Knutson and Columbia (Md.) National Inc.   
"If a company survived 1994, particularly a private company, that's  pretty telling about the abilities of their management," said Gareth Plank,   a stock analyst at UBS Securities. "I think they have a pretty savvy group   of people there."     
  
Another mortgage lender has chosen to take its home equity business  public rather than joining the parade of companies looking to be acquired. 
Imperial Credit Industries is issuing 4.6 million shares of common stock  in Southern Pacific Funding Corp. and retaining 64.5% ownership of the   Riverside, Calif.-based home equity lending unit.   
Imperial, based in Lake Oswego, Ore., is primarily a wholesale lender.  About 83% of its production is first mortgages. 
Mr. Plank of UBS said the spinoff signifies Imperial Credit's commitment  to the mortgage business. 
  
"It creates better total valuation," Mr. Plank said. He added that  bringing Southern Pacific public allows the market to decide whether the   unit's home equity business is worthwhile. "If the market does not like it,   maybe you as parent shouldn't be in that business," he said.     
Natwest Securities Ltd., Montgomery Securities, and Prudential  Securities Inc. are the underwriters for the stock offering.
