Saudi developer Dar Al Arkan has lowered price guidance on its planned Islamic bond issue. The company, which is planning to raise at least $300 million from a five-year Islamic bond, revised its guidance lower to around 6 percent from initial yield guidance of 6.25 percent. An update from lead arrangers on Monday indicated that order books were over $500 million. Dar Al Arkan has picked Bahrain-based Bank Al Khair, Deutsche Bank, Emirates NBD, Goldman Sachs and Qatari pair Masraf Al Rayan and QInvest to arrange the potential sale.
