(6) Early 2002: With complexity growing within Tyco's subsidiaries, in January 2002, Tyco announced a plan to split the business into four separate companies. However, this plan was abandoned after a downgrade in its credit rating and a significant drop in its stock price. Later that month, Tyco's acquisitions continued throughout all of its segments: the Electronics segment acquired Communications Instruments, Inc. The Healthcare segment bought Paragon Trade Brands. The Engineered Products and Services segment acquired Clean Air Systems. And the fire and Security segment of Tyco acquired SBC/Smith Alarm Systems, DSC Group, and Sensormatic Electronics Corp. For all the acquisitions Tyco made in 2002, the company also incurred extensive losses. During the first quarter of 2002, following the recession of the previous year, the electronics segment recorded a charge of over $2 billion, related to massive overcapacity of fiber-optic cable, which in turn affected the in-process buildout of Tyco's global undersea fiber-optic network, known as Tyco Global Network (TGN). TGN generated a loss for fiscal 2002 of over $3 billion, with a restructuring charge of over $500 million. Construction of TGN was eventually completed in 2003. The electronics segment also recorded over $1 billion in restructuring charges in 2002 from inventory write-down and facility closures. In addition, 2002 struck Tyco with two goodwill impairments, the first for over $500 million in the second quarter, due to their fiber-cable overcapacity issue and other corporate problems. The second, costing the electronics segment $250 million related to sales issues in Power Systems, Electrical Contracting Services, and the Printed Circuit Group
