DUBAI: Dubai's Jebel Ali Free Zone (JAFZ), which operates one of the largest customs-free areas in the Middle East, has repaid a 2 billion dirham ($544.6 million) Islamic loan to banks almost four and a half years ahead of its scheduled maturity, the company said on Monday.

The early repayment of the debt, part of a package which averted a potential default by JAFZ in 2012, highlights the divergence among Dubai state-controlled entities since the worst of the emirate's sovereign-linked debt crisis at the turn of the decade.

While some, including property developer Nakheel, have returned cash to banks ahead of schedule, others have required subsequent restructuring to cope with their financial burdens.

"Early repayment manifests the true commitment of the shareholder and government of Dubai to reduce the debt of (the) overall Dubai World Group," said Sultan Ahmed bin Sulayem, chairman of Economic Zones World, the holding company of JAFZ. EZW was acquired last year by ports operator DP World from the parent firm of both companies, Dubai World, a transaction which eased the burden on the state conglomerate ahead of its own debt repayment in May 2015.

Dubai World made that repayment as part of a revision covering the terms of $14.6 billion of debt. Other government-linked firms, including Drydocks World and Limitless, are also seeking to reschedule debt.

JAFZ's 2 billion dirham Islamic facility was arranged in June 2012 to partly refinance the company's maturing $2 billion sukuk issued in 2007.
