I like the cash flow statement, as in practice it was used the most for mergers & acquisition work. In a startup, we expect operating cash flows to be zero or negative, financing cash flows to be positive, and investing cash flows to be negative. If a company is ten years old, and we see negative flows for operations as well as positive flows from investing, we have concerns as management is selling in the future to pay the present.

Why would it matter how long the company has been in business?
