"This is going to hurt their balance sheets." Lucent Technologies Inc., of Murray Hill, N.J., claims they are owed at least $123 million, a number much greater than the $31 million listed in Global Crossing's bankruptcy filing, The Wall Street Journal reported Friday. The filing states Paris-based Alcatel is owed $31 million; Nortel Networks, of Ottawa, Ontario, $13.8 million; Cisco Systems, of San Jose, Calif., $12.6 million; and Juniper Networks, of Sunnyvale, Calif., $3.6 million. However, it is noted that Lucent claims they have taken sufficient provisions, an accounting practice in which a company anticipates problems with a customer, thus keeping their balance sheet clean, said Ariane Mahler, an analyst with Dresdner Kleinwort Wasserstein, the investment banking division of Dresdner Bank, based in London. However, losing money in the short term from unpaid debts is the least of their worries, said Mahler. "Where are the future revenues going to come from?" asks Mahler.
