Regarding material events for the month, during the last week of April, the World Health Organization's epidemiological alert level was raised from a ‘Phase 3’ to a ‘Phase 4’, and currently to a ‘Phase 5’ alert due to the AH1N1 flu virus epidemic, which the Company estimates will adversely affect both domestic and international passenger traffic flows and has already led to the cancellation of flights arriving from Canada, the United States, as well as some domestic flights due to a lack of passengers.

The effects of the AH1N1 flu on traffic and operations at GAP’s airports will depend on the duration of the sanitary crisis in Mexico, as well as tourists’ perception of the containment of the epidemic.
