(5) 2000-2001: Tyco's aggressive acquisition strategy continued into the early 2000s, with the purchases of General Surgical Innovations, Siemens Electrochemical Components, AFC Cable and Praegitzer. The additions gave Tyco an ending fiscal 2000 year revenue exceeding $28 billion, near $2 billion coming from the sale by a subsidiary of its common shares. In the fiscal 2001 year, Tyco acquired Mallinckrodt Inc. and Simplex Time Recorder Company which it later merged in January 2002 with Grinnell Fire Protection to form an indirect wholly owned subsidiary, SimplexGrinnell LP, the world's largest fire protection company. For the year ended September 2001, the company's book value exceeded $110 billion. However, the company more than doubled its long-term debt, by over $80 billion. In October 2001, the Engineered Products and Services segment acquired Century Tube Corp, and followed it by buying Water & Power Technologies in November 2001. The following November, the Tyco Electronics segment acquired Transpower Technologies. The next month, the Plastics and Adhesives segment acquired LINQ Industrial Fabrics, Inc
