Kuwaiti firm Investment Dar is making a renewed legal push to secure ownership of a major asset at the centre of its long-running restructuring process. The case is a rare test of Kuwait's Financial Stability Law, introduced in 2009 to assist debt renegotiations. The firm has been embroiled in litigation over a stake in Kuwait's Boubyan Bank, which it sold to Commercial Bank of Kuwait (CBK) in 2008, with the right to buy it back. CBK currently holds a 19.9 percent stake in Boubyan. Investment Dar hopes to sell the stake to repay creditors. For its part, CBK said last week it cancelled a proposed 120 million dinar capital-boosting bond due to "legislative and technical issues".
