SAO PAULO, Aug 1 (Reuters) - Canada's Brookfield Asset Management BAMa.TO is in talks to acquire a 30% stake in Brazilian sanitation company Brookfield Ambiental from the workers severance fund FGTS, two people with knowledge of the matter said.
A deal could value the stake in BRK Ambiental, as the company is known, at around 2 billion reais ($520 million), said the sources, who asked for anonymity because the talks are private.
The stake, owned by workers' severance fund FGTS, is managed by Brazilian state bank Caixa Economica Federal, which has been divesting from most of its noncore assets.
Caixa Economica and Brookfield did not immediately reply to requests for comment.
Caixa has sold stakes it owned in Brazilian reinsurer IRB Brasil Resseguros SA IRBR3.SA and in state-controlled oil company Petroleo Brasileiro SA PETR4.SA . So far it has sold around $2.6 billion in equity stakes. Caixa proposed, as manager of FGTS, an initial public offering of the water and sewage company, but Brookfield is not interested in having a separate listed entity in Brazil and decided to make an offer to acquire the stake from FGTS.
Brookfield acquired a 70% stake in the company in October 2016 from construction conglomerate Odebrecht SA ODBES.UL , for around 3.5 billion reais ($910 million).
Since the acquisition, Brookfield changed the name of the company and injected capital, so the final value of the deal should reflect the investments over the last two years, one of the sources said.
There is no time frame for the deal because the workers' severance fund board and Caixa are discussing the best criteria on which to value the assets, and apply them to all the stakes owned by FGTS. ($1 = 3.8463 reais)
