The rules require advisers to hedge funds and other private funds to register with the SEC, establish new exemptions from SEC registration and reporting requirements for certain advisers, and reallocate regulatory responsibility for advisers between the SEC and states.

SEC chairman Mary Schapiro said these rules will fill a key gap in the regulatory landscape. In particular, their proposal will give the Commission, and the public, insight into hedge fund and other private fund managers who previously conducted their work under the radar and outside the vision of regulators.

In addition, the Commission amended rules to expand disclosure by investment advisers, particularly about the private funds they manage, and revised the Commission’s pay-to-play rule.

The rules implement a transitional exemption period so that private advisers, including hedge fund and private equity fund advisers, newly required to register do not have to do so until 30 March 2012.

The rules regarding exemptions for venture capital fund and certain private fund advisers are effective 21 July 2011.
