1. Choose a firm whose stock is traded on stock exchanges, and then visit its website.
2. Go to the Investor Relations area of the website (or a similarly titled area such as Investor Information, Investors, Investor Resources, etc.), and then locate the firm's annual report (typically found under Financial Reports, Financial Statements, Financial Facts, Financial Document, or some such link).
3. From the report, determine how the firm is financing investment in assets: long-term debt, preferred stock, and common stock.
