After the bell on Tuesday, Standard & Poor's revised the company's long-term debt rating to negative from stable while reaffirming its long-term corporate credit rating of BB-minus, which is the third-highest junk rating. "The ratings reflect Isle's aggressive growth strategy, the second-tier market position of many of its properties, and increased expansion capital spending," said Standard & Poor's credit analyst Peggy Hwan. Isle said it will open a 40,000-square foot casino on a nine acre spread in Rosemont, Ill., near Chicago's O'Hare International Airport by the end of the year. The accelerated construction timeline -- as well as the gaming license -- are the result of the bankruptcy of Emerald Casino, which had already built a parking garage and much of the infrastructure on the Rosemont property before filing for bankruptcy.
