ZUG, Switzerland, May 24, 2012 /PRNewswire/ -- Allied World Assurance Company Holdings, AG (NYSE: AWH) announced today that Allied World U.S. has launched a new product and risk management service for its Environmental insurance policyholders. The new Contractors Professional and Pollution Liability (CPP) Policy is part of Allied World's expanded product offering for the Construction industry. The company has also introduced a new, complimentary 24/7 Environmental Helpline service available to all Environmental insurance policyholders in the U.S. as part of Allied World's ongoing commitment to provide value-added risk management services to clients. The new CPP Policy protects contractors and consultants working in both the Construction and Environmental industries against professional acts, errors and omissions, and the various environmental liabilities that are often not covered by a general liability policy. This policy covers contractor-related professional liability as well as bodily injury, property damage, environmental damage, clean-up costs and emergency clean-up costs caused by pollution incidents arising from an insured's operations. By combining the features of the Contractors Pollution Liability (CPL) Policy with errors and omissions coverage for professional damages and mitigation expenses incurred during the course of performing operations and services, this product is ideal for general contractors, construction managers, trade and specialty contractors. This product is also an important professional liability solution for environmental consultants, contractors and environmental laboratories. In addition to the new Environmental policy, Allied World's U.S. Environmental Department is unveiling access to a new 24/7 Environmental Helpline, which is available, at no additional charge, to all Allied World U.S. Environmental insurance policyholders. Allied World U.S. offers access to this helpline through a strategic relationship with Hydro-Environmental Technologies, a highly regarded, multi-disciplinary, full-service environmental, health and safety and risk management consulting company. Policyholders have access to timely answers to their questions regarding Environmental Health & Safety (EH&S) issues, regulatory matters and industry best practices effecting day to day business.
