In one of the first lawsuits to go to trial involving Bernard L. Madoff's massive fraud, a group of investors is nearing a settlement with a Connecticut bank that they said should have uncovered the Ponzi scheme years before it collapsed, the Wall Street Journal reported today. The tentative settlement, reached just as the two sides were about to deliver closing arguments, may return a fraction of the $60 million that the investors said they lost. But any sums could be a blow for the bank, Connecticut Community Bank and its branch, Westport National Bank, which are controlled by William R. Berkley, chairman of a large insurance company. The bank, which has reported losses for the last four years, also faces a $28 million lawsuit from the trustee overseeing the liquidation of Madoff's securities firm and it is operating under a formal order from the Office of the Comptroller of the Currency demanding operational improvements as a result of what the regulator said were "unsafe and unsound" practices and violations of the law.
