Mary Schapiro, chairman of the Securities and Exchange Commission, is planning to use an appearance before a House subcommittee to urge lawmakers to increase the agency's budget. "As we continue to implement the Dodd-Frank Act and begin our JOBS Act rule making, we will need additional resources, including new subject matter experts, to make the transition to new rule regimes as smooth as possible and to streamline existing processes for market participants while still maintaining essential protections for investors," Schapiro notes in testimony prepared for a House Financial Services subcommittee.
