Some large shareholders in Grupo Oi SA could sue partner Portugal Telecom SA if a debt investment made by the latter ends up in default, which could delay the companies' planned merger, a source close to the deal said, Reuters reported. Shareholders of Rio de Janeiro-based Oi want to push Portugal Telecom to take a smaller stake in the company resulting from the merger, depending on the outcome of the debt negotiations later on Tuesday, said the source, who declined to be identified because of the sensitivity of the issue.

Less than three weeks before Argentina risks a default, government officials still haven’t met with hedge funds who won a court ruling forbidding the country to make bond interest payments before they get $1.5 billion, Bloomberg News reported. “We have not seen any indication that Argentina is serious about even beginning a negotiation,” NML Capital, one of the holders of bonds from Argentina’s 2001 default that sued for full repayment, said in a statement July 11.

A Netherlands-based subsidiary of Brazilian tycoon Eike Batista's bankrupt shipbuilding and shipleasing unit OSX Brasil SA suspended payments to creditors after being granted protection by a Dutch court, Reuters reported. According to a securities filing on Thursday, OSX sought protection for its OSX WHP 1&2 Leasing BV unit after an unnamed "alleged creditor" asked a court to order payment in a way that threatened OSX's obligations to other creditors.

Holdout investors who rejected Argentina’s debt restructurings in the wake of its $95bn default have said they are prepared to give Buenos Aires extra time to settle, but only if the country negotiates in good faith, the Financial Times reported. Argentine officials met in New York on Monday with a mediator in the dispute. The country needs to reach a rapid deal with holdouts if it is to avoid a second default. Under a US court ruling, Argentina cannot service its restructured bonds unless it also settles with the holdouts in full.

Argentina will not make a formal offer to settle its dispute with holdout investors in its sovereign debt at its meeting on Monday with a court-appointed mediator, an Argentine daily wrote on Saturday, citing Economy Ministry sources. After a string of adverse U.S. court decisions, Argentina has until the end of July to settle with a group of creditors who refused to accept the terms of its restructurings following its 2002 default on $100 billion of debt.

State-run Caixa Econômica Federa l, Brazil's largest mortgage lender, is considering options to get rid of bad loans and free up capital, including the sale of pools of distressed credit to investors, two sources said on Wednesday, Reuters reported. Up to 3.2 billion reais ($1.4 billion) worth of defaulted loans could be sold to funds that specialize in dealing with distressed assets, the sources said. Alternatives under study include the sale of securities backed by pools of bad loans, according to the first source, who declined to be identified because the matter has yet to be decided.

Argentina’s President Cristina Fernandez de Kirchner has less than a month to choose between two unpalatable options: fulfilling a vow never to pay off creditor hedge funds, or negotiating with them to avoid a rerun of the 2001 debt crisis that forced a predecessor to flee the presidential palace in a helicopter, Bloomberg News reported.

Bank of New York Mellon Corp. must return a $539 million deposit from Argentina intended for restructured bondholders, a U.S. judge ruled, calling the transfer an “explosive action” that disrupted potential settlement talks with holders of defaulted debt, Bloomberg News reported. U.S. District Judge Thomas Griesa in New York has ruled that Argentina can’t pay holders of its restructured debt without also paying more than $1.5 billion to a group of defaulted bondholders, raising the possibility of a new default as the South American nation approaches a June 30 payment deadline.

Governments have a long history of borrowing abroad and not repaying their debts. The first recorded sovereign default was in the 4th century BC when ten Greek cities failed to honour loans from the temple of Delos. Yet there are still no clear rules governing what happens when sovereigns do not pay up, The Economist reported. The murkiness was highlighted this week when Argentina seemed to offer, under duress, to negotiate with the 8% of its bondholders who refused to accept any losses after a huge default in 2001.

Argentina is being pushed toward a new default after a U.S. Supreme Court decision favored holdout creditors seeking payment on bonds it defaulted on in 2001-2002, Economy Minister Axel Kicillof warned United Nations diplomats on Wednesday, Reuters reported. Referring to those creditors as "vulture funds," Kicillof said the June 16 decision by the top U.S. court to deny Argentina the chance to appeal a lower court ruling means it faces an insurmountable payment to all existing bondholders, given it has just $28.5 billion in foreign currency reserves.
