The ICSID Reports provide the only comprehensive published collection of arbitral awards and decisions given under the auspices of the World Bank's International Centre for the Settlement of Investment Disputes or pursuant to other multilateral or bilateral investment treaties, including in particular the North American Free Trade Agreement (NAFTA) and the Energy Charter Treaty (ECT). These decisions, which are fully indexed, make an important contribution to the growing body of jurisprudence on international investment. The ICSID Reports are an invaluable tool for practitioners and scholars working in the field of international commercial arbitration or advising foreign investors. Volume 17 of the ICSID Reports includes the decisions on jurisdiction, merits and annulment in Helnan v. Egypt States, and the awards in Inceysa v. Salvador, Telenor v. Hungary, World Duty Free v. Kenya, UPS v. Canada, and Plama v. Bulgaria.
