(Telecompaper) Brazilian operator Oi is close to reaching a tentative agreement with banks to postpone BRL 14 billion in debt payments without any discounts, reports O Globo. The proposal on the table is to divide up this amount over a period of 15 years, a source familiar with the process said. Banco do Brasil is the largest creditor, with BRL 4.4 billion, followed by BNDES (BRL 3.3 billion), China Development Bank (BRL 2.4 billion), Caixa Economica Federal (BRL 1.9 billion) and Itau (BRL 1.5 billion). Financial institutions account for just over 21 percent of the total debt of the company, of approximately BRL 65.4 billion. According to the same source, the banks will not accept shares of the operator in exchange for debt.
