Dana Gas PJSC, a producer of natural gas in Egypt, Iraq and the United Arab Emirates, may seek to roll over part of the $700 million Islamic bonds maturing next year, the chief executive officer said. The company, which has about $344 million in cash, is in discussions with lenders about its future debt mix, Patrick Allman-Ward said in an interview on Bloomberg Television Sunday. “We are looking at different ways in which we can go forward and structure our debt,” Allman-Ward said.
