The annual report to
shareholders is the principal document used by most public companies to
disclose corporate information to their shareholders. It is usually a
state-of-the-company report, including an opening letter from the Chief
Executive Officer, financial data, results of continuing operations,
market segment information, new product plans, subsidiary activities,
and research and development activities on future programs.
The Form 10-K,
which must be filed with the SEC, typically contains more detailed
information about the company’s financial condition than the annual
report.
