The document summarizes key highlights of the Companies Bill 2013 that was passed by the Rajya Sabha in August 2013. Some of the key changes introduced include a uniform financial year for all companies from April to March, allowing private companies to have up to 200 members, introducing one person companies, simplifying the object clause, and expanding the types of securities governed by the bill. The bill also eases rules around buybacks, deposits, auditing and rotations, and introduces concepts like women directors and corporate social responsibility.
