Settlement talks may be in the works as the long-running trial over Nortel Networks Corp.'s billions winds to a close this week, Dow Jones Daily Bankruptcy Review reported today. Lawyers who have been battling for at least three years over how to divide $7.3 billion raised in the liquidation of the onetime telecommunications giant last week filed court papers that refer to discussions that could end the fighting. Nortel's various national factions have been caught up in a pitched battle over how to allocate the company's money among competing national units. Judges in Toronto and Wilmington are reviewing the bond interest briefs filed this week by Nortel Canada and Nortel U.S., an exchange sparked when it was suggested that getting a fast answer on the bond interest rate could advance the cash trial.
