Tyco International Ltd. announced this week that it is breaking itself into three publicly traded companies. So what happens to the global manufacturing company’s corporate legal department and to the regional lawyers around the world who serve its various business segments?

Tyco isn’t saying. So far, all we know is what the company filed this week in an 8-K report to the Securities and Exchange Commission, and what CEO Edward Breen and CFO Frank Sklarsky said during a conference call with analysts.
