Casino operator Caesars Entertainment Corp (CEC) has convinced more junior creditors to sign on to the restructuring plan for its bankrupt main unit.

On Monday, CEC and its Caesars Entertainment Operating Co (CEOC) subsidiary announced a restructuring support agreement with holders of “a significant amount” of CEOC’s second lien debt. About $5.2b of CEOC’s total $18.4b debt is held by junior bondholders.

Coupled with spillover from previous deals with other creditor classes, 37% of CEOC’s second lien hoteholders have now agreed to the company’s restructuring plan. CEOC needs to hit the magic number of 50.1% in order for these agreements to take effect.

Monday’s deal calls for cooperating second lien creditors to recover at least 46 cents on the dollar. Assuming the 50.1% threshold is reached, CEOC will boost the recoverable amount by another four cents on the dollar, with a further five cents on the dollar if CEOC can convince “at least two thirds” of second lien noteholders to sign on the dotted line.
