(1)		Note that preliminary passenger traffic figures for 2019, as well as January 2020 for Ezeiza Airport, in Argentina, were adjusted to include additional inbound passengers not accounted for in the initial count, for an average of approximately 5% of total passenger traffic at Ezeiza Airport and 1% of total traffic at CAAP, during that period. Importantly, inbound traffic does not affect revenues, as tariffs are applicable on departure passengers.
(2)		Cargo volumes in Uruguay were rectified from January 2019 to June 2020, to reflect all cargo passing through the cargo terminal, instead of air cargo only.
