Reading a statement of cash flows¶
Every section so far has been about building the statement of cash flows correctly. This one is about reading a finished statement the way a lender or an investor actually reads it. Costco's net income and its operating cash flow are never quite the same number, and that gap is not a mistake to track down; it's the whole point of having two different measures of performance. Once you can read what the gap says, and what the signs of the three sections say about a company's stage in life, a statement of cash flows stops being a math exercise and starts being a diagnosis.
Net income is an estimate; cash is a fact¶
Net income depends on judgment calls: how long equipment will last, when a sale is really earned, how much of this year's revenue will actually be collected. Two honest accountants, given the same facts, can land on two different net income numbers. Cash doesn't have that problem: a dollar either moved into the bank or it didn't. That is why banks deciding whether to renew a loan, and investors deciding whether to buy stock, read operating cash flow alongside net income instead of trusting net income alone. A company can flatter its earnings with optimistic estimates for years; cash is much harder to fake.
Common mistake: net income is the cash a company generated
Cobalt Tutoring can report $120,000 of net income and only $70,000 of operating cash flow in the same year, and neither number is wrong. Net income recognizes revenue when it's earned and expenses when they're incurred, whether or not cash has changed hands. Operating cash flow strips out those timing differences and reports what actually moved. The two measure different things on purpose; they aren't supposed to match.
Depreciation is the clearest case of net income subtracting something that never touched cash. Recording $12,000 of depreciation lowers net income by $12,000, but no cash left the business that day; it left when the equipment was purchased. That is why the indirect method adds depreciation back to net income on the way to operating cash flow.
Common mistake: adding back depreciation brings in cash
The add-back can look like depreciation is a source of cash, the way collecting from a customer is. It isn't: depreciation is added back only to cancel a subtraction that never involved cash in the first place. It gets you back to zero, not into positive territory.
The operating-cash-to-net-income ratio¶
Dividing operating cash flow by net income shows how much of reported earnings actually showed up as cash. A ratio near 1.00 says the two measures roughly agree. Copperleaf Catering turned $245,000 of net income into $420,000 of operating cash flow, a ratio of 1.71, often a sign that depreciation and other add-backs were large relative to earnings. A ratio well below 1.00 is worth a closer look: net income may be resting on receivables or estimates that haven't turned into cash yet.
The ratio only means something when net income is positive. Dividing a negative operating cash flow by a negative net income produces a positive number that looks reassuring and hides the fact that both figures are bad, so for a company with a loss, read the two figures side by side instead of computing a ratio.
Free cash flow: what's left after keeping the business running¶
Free cash flow equals operating cash flow minus capital expenditures. Capital expenditures are the cash a company has to spend on equipment and other long-term assets just to keep running, let alone grow. Free cash flow is what's left over after that cost is covered: cash the company can use to pay down debt, pay dividends, buy back stock, or expand beyond what maintaining the current business requires.
Computing free cash flow
Marlow Landscaping's operating cash flow for the year is $300,000. It spent $180,000 buying new mowers and trucks. Free cash flow is $300,000 minus $180,000, or $120,000. That $120,000 is available for anything beyond keeping the fleet running.
Free cash flow can be negative even with positive operating cash flow, if a company is investing heavily in new equipment; that isn't automatically bad, since growth spending can pay off later.
Three sections, three stages of a company's life¶
The signs of the three sections together tell a story about a company's stage in life. No single year proves anything by itself: a mature company can have an unusual year, a one-time asset sale or a big financing round, so look for a pattern across several years before labeling a company.
| Stage | Operating | Investing | Financing | What's happening |
|---|---|---|---|---|
| Start-up | Negative | Negative | Positive | Not yet cash-generating; buying assets with cash raised from investors or lenders |
| Mature | Positive | Negative | Negative | Operations fund the company's own equipment purchases, with cash left to repay debt or reward stockholders |
| Declining | Weak or negative | Positive | Negative or small | Operations have stopped generating much cash; the company is selling assets instead of buying them, and little new money is coming in |
Northstar Moving fits the declining pattern: negative operating cash flow, positive investing cash flow from selling trucks, and negative financing cash flow, since no new money is replacing what operations aren't generating. The same signed figures for a company buying equipment with new financing instead would tell a start-up story. The next section pulls every learning objective from this chapter together into one summary and a timed warm-up.
Pause and work¶
Start by watching Juniper Web Design and Copperleaf Catering worked in full: one company still burning cash to fund its growth, the other comfortably profitable in cash terms too. Then fill in the missing ratio for the mature company and the missing free cash flow for the declining company in a three-company lineup. Finally, read a fresh set of companies of your own and place each one in its stage, with new numbers every time.
