The Securities and Exchange Commission could issue a civil injunction against Standard & Poor’s for allegedly violating securities laws when rating a 2007 offering of collateralized debt obligations tied to subprime mortgages. S&P’s parent company, The McGraw-Hill Cos. (MHP), reported the possibility of an SEC injunction in a securities filing Monday. McGraw Hill said in a statement the Wells notice it received from the SEC “is neither a formal allegation nor a finding of wrongdoing.” However, the firm said the SEC is considering an injunction against S&P complete with civil penalties, disgorgement of fees and other relief to make the parties whole. The company can now respond to the regulator’s request for information regarding the $1.6 billion Delphinus CDO 2007-1 issuance before the SEC brings charges. Write to Kerri Panchuk.
