How to prepare a statement of stockholder's equity?

Not clear from this short question what it is you need to know. Private company? Public? A simple company with common stock, profits and dividends, or one complicated by stock options, converted debt/stock, comprehensive income, etc.? My easiest suggestion would be to pick a couple of mid-sized SEC filings and see what those stockholder equity statements look like and copy them. Are you audited/reviewed -- if so, ask your CPA's for a template and some guidance. If not -- why are you even doing it?
