(Adds agreement with small creditors, other possibilities of delay requests by creditors)
SAO PAULO, Oct 20 (Reuters) - Several groups of Oi SA creditors have requested the postponement of a meeting scheduled for Monday to discuss the Brazilian phone carrier's bankruptcy protection process, a representative for a key bondholder group said on Friday.
The International Bondholders Committee said it had asked for the delay along with the Ad Hoc Group of Oi Bondholders, Banco do Brasil, state development bank BNDES and Caixa Economica Federal, which all have claims on debt-laden Oi.
Oi Chief Executive Officer Marco Schroeder told journalists in Brasilia the carrier is "totally prepared" for the meeting but said it would take advantage of any additional time to continue negotiations.
Should a Rio de Janeiro judge grant the request for a delay, creditors and the company will have another chance to reconcile competing restructuring proposals 16 months into Brazil's largest in-court reorganization.
Oi wants to restructure 65.4 billion reais ($20.5 billion) in debt by offering bondholders a 25 percent equity stake, a move that would imply a 73 percent haircut for creditors, according to an independent analysis by Banco Itau BBA.
Major bondholder groups represented by restructuring firms G5 Evercore and Moelis & Co, which hold about $22 billion reais in Oi's debt, have put forth a counter-offer which would give them 88 percent of Oi's equity.
While bondholders have publicly condemned Oi's offer, they are also trying to avoid a liquidation at all costs, according to two people with knowledge of the situation.
Oi's assets are worth 40.8 billion reais, according to independent auditor Ernst & Young. That amount could drop to 17.9 billion reais, or less than 30 percent of the value of debt under renegotiation, in a forced sale, according to the auditor.
As a class of creditors, bondholders are ranked behind workers and BNDES, so they would stand to lose more in a liquidation than if the company's terms were accepted, the people said.
Even if the judge does not grant their request to delay the meeting, creditors can still ask to postpone a vote on the restructuring plan once the session begins on Monday.
Oi announced in a statement on Friday that 33,000 small creditors have accepted the company's offer to restructure individual debts of less than 50,000 reais ($15,685).
Preferred and ordinary shares in Oi fell about 2 percent in Friday afternoon trading. ($1 = 3.19 Brazilian reais) (Reporting by Tatiana Bautzer and Gram Slattery; Additional reporting by Marcela Ayres in Brasilia; Editing by Paul Simao and Cynthia Osterman)
