Mexico City, Feb 3 (EFE).- Mexico's Grupo Aeroportuario del Sureste, or Asur, which operates nine airports, and private equity firm Advent International have submitted a joint bid for concessions to expand, maintain and operate three airports in Brazil.

"Advent and Asur submitted their joint bid to Brazil's National Civil Aviation Agency," Asur said in a press release Thursday.

The Brazilian government announced in 2008 its plans to privatize the Sao Paulo, Brasilia and Campinas airports.

The base prices were set at some $1.3 billion for Sao Paulo's Guarulhos airport, nearly $300 million for Campinas and some $42 million in the case of Brasilia.

The winners for each airport will be required to pay the concession fee in annual installments during the term of the concession, Asur said.

"The winning bidding group for each airport will be required to form a joint venture with Empresa Brasileira de Infraestructura Aeroportuaria (Infraero) in which the winning bidding group would be the majority shareholder and Infraero would be the minority shareholder," the press release said.

A bidding group may only be awarded the concession for one airport, it added.

Asur, one of Mexico's largest airport operators, runs the Cancun airport and eight others in the country's southeast. Its main shareholders include mining corporation Grupo Mexico, which holds a 15.4 percent stake.

Last year, Asur Chairman Fernando Chico Pardo expressed his interest in participating in airport privatization processes in Central America and South America, particularly in Guatemala and Brazil
