Investor Leon Black's group paid $192 million for Weyerhaeuser Mortgage  Co., a substantial premium over the value of its $4 billion servicing   portfolio.   
Weyerhaeuser disclosed the price last week upon the conclusion of the  sale. Observers said Mr. Black paid a premium because he was eager to get   into the growing business of lending to people with lower credit ratings.   
  
Speculation about the price has swirled around the mortgage industry  since February, when Weyerhaeuser Corp., the Federal Way, Wash., paper and   forest products giant, said it was selling its mortgage banking unit to WMC   Acquisition Co., a joint venture of Apollo Advisors and Spring Mountain   Escrow.       
Apollo is an investment partnership run by Mr. Black, a former head of  mergers and acquisitions at the now extinct junk bond firm Drexel Burnham   Lambert.   
  
Typically, much of a mortgage bank's profits come from servicing, so  when these companies are sold, the servicing portfolio is the main   determinant of the company's value. At the time of the sale, brokers and   investment bankers said Weyerhaeuser's servicing was worth no more than $80   million.       
But other observers said the price reflects the growth potential of the  company's subprime unit, now known as WMC Equity Services. The subprime   unit originated $500 million of loans to people with poor credit histories   last year. Overall, WMC originated about $3.5 billion in mortgages.     
One source said WMC is looking to sell off the servicing it has in order  to focus predominantly on originating loans to so-called B and C customers. 
  
In a written statement, chief executive Scott A. McAfee, chief executive  of Spring Mountain and WMC, said the company plans to remain a "formidable   competitor" in the subprime business. Mr. McAfee became chief executive of   WMC Mortgage when the deal closed.     
In addition, he said WMC will now securitize loans it originates,  something the company had not been doing before. No mention of the   company's servicing portfolio was made in the statement.   
Last month, H&R Block anted up $190 million for Option One, Fleet  Financial Group's subprime unit. Option One only services about $1.9   billion but originated $1 billion in B and C loans last year.   
Also last month, Resource Bancshares Mortgage Group agreed to issue  about $320 million in stock to merge with Walsh Holding Co., a subprime   lender that had no servicing portfolio but originated $660 million of   mortgages in 1996.     
  
But one investment banker said despite these premiums for B-and-C  originators, the price for WMC was "hard to justify." The investment banker   represented another firm that was interested in bidding for WMC and said   the price it felt was fair for WMC wasn't anywhere close to $192 million.
