RIO DE JANEIRO (Reuters) - United Health Group Inc
The price was determined by the Brazilian unit of Goldman Sachs Group Inc
When the minority stakes are purchased, Amil will be de-listed from the Sao Paulo BM&FBovespa exchange.
The upper range of the Goldman Sach's estimate is 12 percent below the 30.74 reais that United Health paid for its controlling stake.
Under the takeover agreement, United Health will buy out nearly all minority shareholders and raise its stake to 90 percent of Sao Paulo-based Amil, which in addition to insurance operates hospitals.
The remaining 10 percent will be held by Amil founder and Chief Executive Edson Bueno and his partner Dulce Pugliese. Bueno has also agreed to buy $470 million of United Health shares. Bueno will continue to manage the company.
