The recently enacted Jumpstart Our Business Startups Act (JOBS Act) directs the U.S. Securities and Exchange Commission (SEC) to adopt rules that remove the existing prohibition against general advertising and general solicitation in private placements exempt from registration under Rule 506 of Regulation D, as long as the securities are sold only to accredited investors.

SEC Adopts Final Rules on Performance-Based Fees

SEC Overhauls Form ADV Part 1A to Conform to New Dodd-Frank Requirements

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 has significantly changed how investment advisers are regulated.
