Disclosure requirements under US securities laws arise principally from periodic reporting and filing requirements. Companies registered with the Securities and Exchange Commission (SEC) must provide reports annually and quarterly in prescribed forms. The MD&A is a required part of the disclosure in a registration statement under the Securities Act of 1933 or Form 10-K or 10-Q under the Securities Exchange Act of 1934, where management of the issuer explains, in narrative form, the financial results of operations and financial liquidity of a company.
