Nortel Networks Inc., the telecommunications company being liquidated in bankruptcy, may soon settle a fight with its Asian and Latin American units over their share of more than $7 billion Nortel made from asset sales, Bloomberg News reported yesterday. The company may reach a settlement in the next few weeks with its so-called fourth estate, which includes units in China, Australia and Mexico, Nortel attorney James Bromley, with the law firm of Cleary Gottlieb Steen & Hamilton LLP, said yesterday. Nortel's three main so-called bankruptcy estates are made up of defunct operating units in the U.S., Canada and Europe. Those groups have been battling for more than a year over the best way to split more than $7 billion collected by selling businesses and a cache of 6,000 patents.
