Report Parameters

This report relates to the company’s operations in the period between the 1st of January and the 31st of December 2008, and follows on from ASUR’s 2007 Social Responsibility Report which can be consulted at www.asur.com.mx.

This report is produced primarily as a tool for the stakeholders of ASUR, with the aim of creating a greater degree of transparency concerning the company’s operations and providing information of interest in relation to the company’s response to stakeholders’ specific concerns. It is intended to complement ASUR’s Annual Financial Report, which contains in-depth information on the financial performance of ASUR during the same period, and it will therefore focus in particular on social and environmental matters without including detailed financial data.

The report covers the operations carried out directly by ASUR in all nine airports that belong to the company, as well as in the other major subsidiaries of company.

An analysis has been carried out to determine the main stakeholders of the company and the aspects of our business that are of particular interest to them. In general terms, ASUR’s stakeholders can be divided into internal and external stakeholders. The former include the company’s employees, shareholders and the members of the company’s Board of Directors and corporate governance committees. ASUR’s external stakeholders can be further subdivided into two main categories: those that have a relation with the region where the company’s airports are located, including local residents, local authorities and the local business communities; and those that are involved in the company’s aeronautical activities, including airlines, passengers and national and international aviation authorities.

It is our firm belief that the environment, and specifically what ASUR is doing to reduce its environmental impacts, is one of the primary concerns of all our internal and external stakeholders. We also believe that the working conditions we provide for our employees, and wider issues such as ASUR’s record with regard to respect for human rights and the measures we have implemented to prevent corruption, are of particular interest to our most important stakeholders. Consequently we will focus on these fundamental issues in this report.

In accordance with the guidelines published by the Global Reporting Initiative, a not-for-profit organisation established to create a framework for sustainability reporting, we hope to expand the scope of this report for subsequent reporting periods to include issues such as safety and security in our airports, the efficiency and quality of our airport infrastructure and the various activities undertaken by the company to drive economic development in the regions where we operate.
