Basis of preparation
The payments disclosed, which are on a cash basis in U.S Dollars, are based on where the obligation for the payment arose (i.e. at a project or corporate level). Where a payment or a series of related payments do not exceed £86,000, they are not required to be disclosed under the UK Regulations, however this has been disclosed in aggregate at a corporate level for clarity over obligations.
All of the payments disclosed in accordance with the Directive have been made to National Governments of Alberta, Colombia and Ecuador, either directly or through a Ministry or Department of the National Government and to Local Community Councils or municipalities in Canada, Colombia, Ecuador and the United States of America.
