ALEXANDRIA, Va. - The National Credit Union Administration has  retained the law firm Storch & Brenner to investigate third parties whose   actions might have caused the failure of Capital Corporate Federal Credit   Union.     
Storch & Brenner, based in Washington, was selected July 28 because of  its experience in investigating securities claims for the Federal Deposit   Insurance Corp., said NCUA trial attorney Steven Widerman.   
  
"We're conducting a comprehensive investigation of possible claims  against third parties whose conduct may have led to the demise of Cap   Corp," he said. Targets of the investigation include broker-dealers,   auditors, and former officers and directors.     
"Depending on what the report says, the agency will decide on whether  and how to pursue claims," he said. Storch & Brenner is expected to submit   its findings to the agency in four to six months.   
  
Storch & Brenner, which the agency selected from among 24 competing  firms, will be paid $125 to $190 per hour, depending on the lawyer, Mr.   Widerman said. The agency has set aside $1 million from the Cap Corp   liquidation to cover costs of the investigation and any litigation.     
The demise of Cap Corp ate up $37 million of the institution's capital  and about $23 million of capital deposits by Cap Corp's member credit   unions.   
If the agency pursues claims, it could have a hard time, said Steven  Bisker, a former NCUA attorney who now works with credit unions. 
  
"It could be tough sledding if you have a defendant that can afford to  defend itself," the Alexandria-based attorney said. 
Sources expect the broker Alex. Brown & Sons Inc. to be a major focus of  the investigation, because it sold Cap Corp the bulk of its collateralized   mortgage obligations.   
Further, Howard L. Schwartz, the broker-dealer who worked the most  closely with Cap Corp, was once the Lanham, Md., corporate's investment   officer.   
Mr. Widerman would not comment on the relationship between Brown and Cap  Corp, but press reports have said the NCUA already has referred the matter   to the Securities Exchange Commission.   
  
One of Storch & Brenner's selling points was its experience in customer-  suitability claims regarding securities, Mr. Widerman said. 
In an interview, Alex. Brown chairman A.B. "Buzzy" Krongard pointed out  that NCUA Chairman Norman E. D'Amours told the Senate Banking Committee in   February that Cap Corp had failed because of poor management and lax   oversight.     
"Alex. Brown vigorously and vehemently denies any wrongdoing in this  matter," he said. The firm is "in disbelief," he added, that the agency   would attribute its "own missteps ... to wrongdoing on our part."   
If the NCUA decided to seek claims after the investigation, it could run  into some dead ends, Mr. Bisker said. Going after officers and directors   could be fruitless.   
"Unless you have a defendant with deep pockets, a judgment makes good  wallpaper but little else," he said. 
J. Clayton Brooke, former chief executive of Cap Corp, could not be  located for comment. 
Another target of investigation is Cap Corp's former auditor, Deloitte &  Touche. Laura Fraser, a spokeswoman for the Big Six firm, declined to   comment, citing a confidentiality agreement with its former client.
