Mark Mason, chief financial officer of First Alliance Corp., said this  week that his task with the subprime lender is done so he will return to a   previous career goal-running a banking company.   
Mr. Mason, who was brought in three years ago to help shepherd First  Alliance through its initial public offering, will be leaving Friday to   rejoin Bank Plus Corp., Los Angeles. He will serve as executive vice   president, chief operating officer, and chief financial officer of both   Bank Plus and Fidelity First Bank, its thrift subsidiary.       
  
The news raised eyebrows in the investment community because it came on  the heels of last week's announcement that the American Association of   Retired Persons would join a suit against First Alliance. But the two   events are unrelated, First Alliance executives said.     
In fact, the departure has been planned for months, Mr. Mason said  Tuesday. "I've been here three years, and everything I've wanted to   accomplish I've done."   
  
Moving to Bank Plus, which has $4.2 billion of assets but only a small  portfolio of loans, offers opportunities to build a credit card and   mortgage business, he said.   
Fidelity First was "one of the last thrift cleanups," he said, and is  now "ready to start lending again." 
First Alliance agreed to purchase a Standard Pacific Savings last fall,  but the agreement expired without a go-ahead from the Office of Thrift   Supervision.   
  
First Alliance's chief executive, Brian Chisick, said the failure to buy  Standard Pacific was key reason for Mr. Mason's decision to leave. 
"His major ambition is to run a major bank," Mr. Chisick said. "He'll do  a marvelous job." 
Mr. Mason, 39, was often named as the most obvious choice to succeed Mr.  Chisick, 59. But Mr. Chisick said in a phone interview Tuesday that he has   "no plans other than to run this company" for the next few years.   
He said he and Mr. Mason remain "good friends."
  
First Alliance shares suffered last week when the AARP said it was  joining a suit alleging that the company took advantage of a senior   citizen. The stock price dipped more than $3, to $12.75, at the start of   trading May 6, when the announcement was made. It had recovered to $13.375   by midafternoon Wednesday.       
The suit has been going on for two years, Mr. Chisick said, and the  company "has tried many times to settle," even offering to rescind the   loan.   
"The attorneys don't want to settle the suits, they want publicity," he  said. 
Despite the initial stock price dip, analysts said the AARP action  probably will not have long-term effects. 
"The AARP issue is still very preliminary," said Jennifer Scutti, an  analyst with Prudential Securities, New York. The litigation could continue   for years, she said.
