International Petroleum Investment Company (IPIC), an Abu Dhabi government-owned energy investor, borrowed $1.5 billion (Dh5.5 billion), two bankers familiar with the deal said. The one-year loan pays interest of 50 basis points or 0.5 percentage point over benchmark rates, which will rise to 75 basis points if IPIC keeps the borrowing in place after a year, said the bankers, who declined to be identified because terms are private. The financing, led by Goldman Sachs Group, JPMorgan Chase and Co and Royal Bank of Scotland, gives IPIC the option to extend for six additional months, the bankers said. IPIC officials didn\'t respond to an email seeking comment. Spokeswomen for Royal Bank of Scotland and JPMorgan declined to comment. A spokeswoman for Goldman Sachs didn\'t immediately respond to an email. They declined to be identified.
