The CFTC’s action against PwC probably came as a result of a shocking CME Group announcement late Wednesday: “It now appears that the firm [MF Global] made … transfers of customer segregated funds in a manner that may have been designed to avoid detection.” These transfers, CME Group said, appeared to have taken place after its audit team showed up last week at MF Global to take a look and found everything to be in order. CME Group couldn’t have been hoodwinked like that if PwC had been doing its job all along. You can’t circumvent controls unless there are none or there are holes. It was PwC’s job to review controls and the adequacy of policies and procedures to support them. [Francine McKenna/AB, Earlier]
