International enforcement also stepped up considerably under Cox. During 2008 the SEC made 556 requests of foreign regulators for assistance with SEC investigations, many of which were connected to potential wrongdoing in the subprime market. Among the significant international cases the Commission brought during this period were the highly publicized 2008 charges against Hong Kong-based insider trading in Dow Jones prior to its acquisition by News Corporation. Under Cox the SEC also brought the largest number of cases in its history charging corporations and their officers with foreign bribery under the Foreign Corrupt Practices Act and imposed record penalties for these cases.
