The bottom line.
Earnings. Profit. Revenue minus costs.
Over time, profit and shareholder value are the same thing. The total value of the shares is equivalent to the stream of expected future profits, discounted for the cost of capital. Forgive us if you find this obvious, but you must be able to relate your decisions and choices to the profitability of your organization. Otherwise, you will not be able to make sound decisions as conditions change.
Do not confuse profit (the bottom line) with revenue (the top line).
