Going forwards, the Company will present a breakdown of the figures for international and domestic passenger traffic, as well as the combined figures.

ASURs management believes that the lower passenger traffic numbers to Cancun and Cozumel during the period were largely the result of the reduction in available accommodation caused by Hurricane Wilma, which struck the region in October 2005 and caused widespread damage to the hotel infrastructure in the region.



Cancuns Municipal Tourism Authority estimates thatof the 27,484 rooms available in Cancun prior to the hurricane 10,918, or 40.0%, were in operation as of December 31, 2005.



The Trust for the Promotion of Tourism in the Mayan Riviera estimates that of 25,170 rooms available in the region, 22,836 or 90.7% were in operation at the end of December2005.



At this time ASUR cannot estimate the impact that these events will have on passenger traffic for fiscal year 2006.
