Revel AC Inc. will file for bankruptcy sometime in the last two weeks of this month, less than a year after its Atlantic City, New Jersey, casino opened, Bloomberg News reported on Friday. The resort will remain open during the court case and the company is in the final stages of preparing the filing, which was pre-arranged with creditors. The company and a majority of creditors plan to use bankruptcy to cut about $1 billion in debt, Revel said last month.
