How far need a bank in merger talks go to steer its officials clear of  insider-trading charges? 
Rochester Community Savings Bank in upstate New York says it did its  homework. Nevertheless, three former officials have been charged. 
  
The bank says it advises officers and directors of securities laws as a  matter of policy. And court papers filed by the Securities and Exchange   Commission confirm it.   
In late 1980s, the documents say, Robert Frame, Thomas Farrell, Timothy  Moriarty signed acknowledgements that they had been so advised. Mr. Frame   and Mr. Farrel were outside directors; Mr. Moriarty was vice president of   financial management.     
  
Indeed in 1993, when talks began on a merger with First Empire State  Corp., Buffalo, the three were reminded of the rules, the documents say. 
But the SEC says all three made illegal trades related to those failed  talks. 
Mr. Frame settled the charges against him without admitting guilt. Mr.  Farrell faces civil and criminal charges. Mr. Moriarty was charged this   month.   
  
In the last analysis there's no way a bank can illegal insider trading  by its officials, especially in an era of frequent mergers, experts say. 
"Even if there's a policy in place and it was adopted and people were  made aware of it, there's no way an institution can ensure 100%   compliance," said David H. Baris, executive director of the American   Association of Bank Directors. "If someone's willing to violate the policy   and the law, you can't stop that person."       
Despite the difficulty of enforcement, however, banking consultants  stress that banks and thrifts should still maintain policies against   insider trading, and should ensure that all directors, officers, and   employees are aware of them, particularly when the institution is involved   in confidential merger discussions.       
Institutions also should periodically update their educational programs  for officers and directors to reflect changes in company policies and the   law, said Joseph I. Goldstein, partner at Crowell & Moring in Washington   and former associate director of enforcement at the SEC.     
  
"It's a very difficult process to ensure secrecy and confidentiality  when you're negotiating with a company that could acquire the institution,"   Mr. Baris said. "But it's one that is essential for the institution   involved and the board members."     
Mr. Baris said the key for banks is to limit the number of people in the  loop about merger discussions and other confidential information, and   clearly discourage officers, employees, and directors from trading at all   during such times. Legal counsel should be present at relevant meetings to   remind insiders of their responsibilities - and potential repercussions   against them.         
Mr. Baris also noted that even privately held companies should have such  policies in place. In fact, the problem can be especially prevalent among   small community institutions whose stock isn't widely traded and whose   officers and directors don't have much experience with insider trading   issues.       
"You only do a merger once," Mr. Baris said. "It's not exactly like they  have life experiences and are familiar with these situations. They really   need qualified people advising them in this area as to how to go about it."   
Having good policies in place is also the best defense for an  institution against liability for insider trading by employees, Mr.   Goldstein said. Federal law includes consequences for an institution's top   executives if they don't take steps to prevent insider trading by   subordinates.
