Kuwait's Investment Dar Co has asked creditors to take a 50% writedown on its debt, as it seeks to meet repayments after defaulting on a loan three years ago. Under the optional plan, creditors will receive a cash payment totaling 5.7% of their outstanding debt and a portion of a new Islamic loan equal to about 44% of their current exposure. Details are not public. Investment Dar's stake in Aston Martin and real estate holdings will be among assets backing the new credit facility.
