The Members are akin to the shareholders of a company and are often referred to as the 'gatekeepers'. However, unlike shareholders of a company, Members cannot take out any money or assets. The Members have ultimate control over the Trust with the ability to appoint some of the Trustees and the right to amend the Trust's Articles of Association (a document which sets out the powers of the Trust itself, the Members and Trustees). The Articles of Association describe how Members are recruited and replaced and how many of the Trustees the Members can appoint to the Board of Trustees. The Members can also remove Trustees. Accordingly, the Board of Trustees submits an annual report on the performance of the Trust to the Members.
