OMA- creating value for our shareholders

Our revenues from aeronautical and complementary services, which account for more than 80% of our revenues, are subject to rate regulation. Aeronautical revenues principally depend on passenger traffic volume, the number of air traffic movements, the weight of the aircraft, the duration of an aircraft's stay, the time of day, and the specific prices charged for each service.

The principal fees for aeronautical services, which are charged to the airlines using our facilities, are:

• Passenger charges
• Landing charges
• Aircraft parking, boarding, and unloading charges
• Aircraft long-term parking charges
• Passenger walkway charges
• Airport security charges

We also earn revenues from charging access and other fees from third-party providers of complementary services, such as baggage handling services, catering services, aircraft maintenance and repair, and fuel at our airports. This category also includes fees for cargo handling and permanent ground transportation, such as taxis.
