Corporate Governance

Posted in About

Amerisur Resources plc is committed to meeting high standards of corporate governance. The Directors are committed to maintaining throughout the Group the highest standards of business conduct and ethics, as well as full compliance with all applicable government laws, rules and regulations (including the UK Bribery Act, which came into effect in 2011). The Group is also committed to prompt and comprehensive corporate reporting and disclosure.

As an AIM listed company, Amerisur is not obliged to comply with the UK Corporate Governance Code ("the Code"), although the Board has used the Code as a guide for best practice guidelines and the Directors intend to comply with its main provisions as far as is practicable for a Company of our size and the international reach of our operations. The Board does not consider that the Company is fully compliant with the September 2014 version of the Code as yet, and as we are committed to continuing our journey of improving corporate governance at Amerisur, we will be seeking to be fully compliant in the future.

The Board of Directors comprises the Chairman, two Executive Directors, and five Non-Executive Directors.

All Directors are subject to election by shareholders at the first AGM after their appointment and to re-election at least once every 3 years.

The Board of Directors holds scheduled Board Meetings approximately six times per year plus such other ad hoc meetings as are deemed necessary to deal with urgent business matters.

The Company has established subcommittees of the Board, comprising an Audit Committee, a Remuneration Committee and a Nominations Committee, each of which has its own terms of reference.
