Cooper Industries Inactive

Cooper Industries plc was incorporated under the laws of Ireland on June 4, 2009, and became the successor-registrant to Cooper Industries Ltd. on September 9, 2009. Cooper Industries Ltd. was incorporated under the laws of Bermuda on May 22, 2001, and became the successor registrant to Cooper Industries Inc. on May 22, 2002. Cooper operates in two business segments: Energy and Safety Solutions and Electrical Products Group. Cooper manufactures, markets and sells its products and provides services throughout the world. Cooper has manufacturing facilities in 23 countries and currently employs approximately 25,800 people. Operations in the United States are conducted by wholly-owned subsidiaries of Cooper, organized by the business segments. Activities outside the United States contribute significantly to the revenues and operating earnings of both business segments. These activities are conducted in major industrialized countries by wholly-owned subsidiaries and jointly-owned companies, the management of which is primarily structured through Cooper’s business segments. As a result of operations outside the United States, sales and distribution networks are maintained throughout most of the industrialized world. In many countries in which Cooper operates, we believe that there are no substantial differences in the business risks associated with operations outside the United States compared with United States activities. However, Cooper is subject to certain political and economic uncertainties encountered in activities outside the United States including trade barriers and restrictions on the exchange and fluctuations of currency. Cooper generates the most non-U.S. revenues in the United Kingdom, Germany, Canada, Mexico, France and the Asia Pacific region. Cooper has operations in India and China and has two majority-owned joint ventures with operations in China. Investments in emerging markets such as China, India, Brazil and The Middle East are subject to greater risks related to economic and political uncertainties as compared to most countries where Cooper has operations.
