Last December, Chile's government announced it would sell its stake in four water companies to pay for reconstruction following the massive 8.8-magnitude earthquake that struck central-southern Chile in February of that year.
The government raised some US$984mn in June with the sale of 30% of metropolitan utility Aguas Andinas, while the state's share in Essbio and Esval was sold for US$564mn. The government pledged to keep a 5% stake in each utility as a way to preserve its veto power.
