Johnson Controls, Inc. (JCI) will have a bigger global presence in the building products market through its acquisition of Tyco, a global fire and security system company based in Cork, Ireland. The combined company will include product, technology and service capabilities across controls, fire, security, HVAC, power solutions and energy storage. The merger enables Tyco to grow in China, where JCI is a leader, and JCI to expand in Europe while saving the companies $500 million over three years in operations. Yet, the merger is highly controversial with JCI moving its headquarters overseas and avoiding $150 million annually in US taxes. For more information: JS, Johnson Controls, and nytimes
