CME Group credit rating cut to 'AA-' by Standard & Poor's

Standard & Poor's earlier today lowered its long-term issuer credit rating on CME Group to 'AA-' from 'AA' and affirmed its 'A-1+' short-term rating on the company. The outlook on the long-term rating is negative. S&P believes CME's financial and credit risk profiles are increasing from the growth of its over-the-counter clearing business and the recent protection it has extended to trading customers of its defaulted clearing members.
