SAO PAULO, Dec 30 (Reuters) - Brazilian miner Vale

has reached an agreement with local authorities to

pay up to some 11 billion reais ($1.78 billion) to renegotiate

two railway concession contracts, the firm announced in a

securities filing on Monday.

Brazil's government has been aiming to remove discounts

given to rail companies by the previous administration when some

received early contract renewals.

In its filing, Vale noted that it has reached agreement on

general terms with the government and land transport regulator

ANTT for the renegotiation of the Carajas and Vitoria a Minas

railways concessions, which in 2020 were extended through 2057.

The company added that the agreement still awaits

additional approvals, and will lead to an increase of 1.7

billion reais in its provisions related to railways concessions.
