* Total required investments reach 18 billion reais
(Adds estimated return, Infraero stake)BRASILIA, Oct 13 (Reuters) - Operators interested in
running Brazil’s largest airport will be required to make a
minimum bid of $1.3 billion, Brazil’s aviation authority said
on Thursday.Brazil, which has seen double-digit annual growth in air
traffic, is planning to expand and modernize its main airports
ahead of the 2014 World Cup and 2016 Olympics in Rio de
Janeiro.Bidding for the rights to build and operate three airport
terminals is tentatively scheduled for Dec. 22, although
authorities say the date depends on rulings by government
watchdogs.Investors have been closely watching the bidding amid
broader uncertainty over Brazil’s investment climate. A heavy
government hand in several industries has raised concern with
some private investors.Earlier this year the government said that Infraero, the
state-owned company that currently runs most airports, will
maintain a veto right on strategic decisions in the
joint-ventures it will form with winning bidders. Infraero will
hold a 49 percent stake in these joint ventures.The winning bidder for Guarulhos, Sao Paulo’s main
international airport, will be charged 10 percent of gross
revenue over a 20-year contract. In addition to airport fees,
the operator will earn 804 million reais in revenues by 2032,
compared with an estimated 373 million reais in 2012, Secretary
of Civil Aviation Wagner Bittencourt said.The estimated return on investment for each of the projects
is 6.46 percent, according to Bittencourt’s office.Required investments at Guarulhos total 5.2 billion reais.Brazil will also auction off concessions at Viracopos
airport, in Sao Paulo state, as well as at the airport in the
capital, Brasilia.Bidders for Viracopos, which requires investments of 9.9
billion reais, will have to offer at least 521 million reais
and will pay 5 percent of gross revenues over a 30-year
contract.
