Operating activities, the indirect way

You already know a company's operating cash flows belong in one bucket. Now you have to build the number that goes in it, and that number is almost never equal to net income. A business can report a healthy profit and still be short on cash, or report a loss and still bring in cash by the truckload. The indirect method is how you get from the number on the income statement to the number on the bank statement, one adjustment at a time. Every adjustment has a reason. Learn the reason and you'll never have to memorize the sign.

Start from net income, then fix it

The indirect method always starts with net income, because net income is the closest thing a company already has to a cash summary; it just isn't cash yet. Net income is built on accrual accounting: revenue counts when it's earned, and expenses count when they're incurred, regardless of when cash moves. So net income and cash from operations start at the same number only by coincidence. The rest of this section is a checklist of everything that separates the two: expenses that never used cash, and timing gaps between when a transaction is recorded and when the cash actually changes hands.

Common mistake: net income is the cash the company generated

Net income measures profit, not cash. A sale on account raises net income the moment it's earned, even though no cash has arrived. A cash purchase of supplies uses cash immediately but doesn't touch net income until the supplies are used up. The indirect method exists precisely because these two numbers disagree, and disagreeing is normal, not a sign of a problem.

Depreciation: added back, not brought in

Depreciation expense lowers net income every year, but it never costs the company a dollar of cash in the year it's recorded. The cash for the equipment went out long ago, when it was purchased. Depreciation just spreads that old cash outflow across the years the equipment is used. So when you start from net income, you've already subtracted an expense that cost no cash this year, and you have to add it straight back to cancel that subtraction out.

That's the whole reason for the add-back. It has nothing to do with depreciation creating cash out of thin air.

Common mistake: adding back depreciation brings in cash

Adding depreciation back does not put cash in the company. It undoes a subtraction that was already accrual, not cash. If a company had zero depreciation, operating cash flow wouldn't drop by that amount; it would just mean net income and cash were closer to begin with.

Working capital: the sign rule

Current asset and current liability accounts are where most of the timing gaps between net income and cash actually live. The rule has two halves, and both halves come from the same idea: figure out whether net income already counted the cash, or whether the cash is still stuck somewhere else.

For a current asset like Accounts Receivable: if the balance goes up, the company recorded more revenue than it collected, so cash is lower than net income implies. Subtract the increase. If the balance goes down, the company collected on sales it recorded earlier, so more cash came in than this year's revenue shows. Add the decrease.

For a current liability like Accounts Payable: if the balance goes up, the company recorded expenses it hasn't paid for yet, so it's still holding that cash. Add the increase. If the balance goes down, the company paid off bills from earlier, so cash went out beyond this year's expenses. Subtract the decrease.

Account type	Balance change	Adjustment
Current asset	Increase	Subtract
Current asset	Decrease	Add
Current liability	Increase	Add
Current liability	Decrease	Subtract

Deferred Revenue, sometimes called unearned revenue, is a current liability, so it follows the liability row exactly, even though it can feel backwards. If Deferred Revenue goes up, customers paid cash before the work was done, so cash came in that net income hasn't recognized yet. Add it. If Deferred Revenue goes down, the company finally did work customers had already paid for, so that revenue is now in net income, but no new cash arrived for it. Subtract it.

Common mistake: more receivables means more cash came in

It's the opposite. Accounts Receivable only grows when the company makes a sale it hasn't collected cash for yet. A rising balance means cash lagged behind revenue, which is why the increase gets subtracted, not added, when reconciling net income to cash.

Gains and losses: the cash is somewhere else

A gain or loss on the sale of equipment sits inside net income, but the cash from that sale belongs entirely in investing activities, which you'll build in the next section. If you left the gain or loss inside operating cash flow, you'd count part of that sale twice: once here, and again when the full sale proceeds show up in investing.

A gain is subtracted from net income in the operating section. The gain already boosted net income once; subtracting it here keeps operating cash flow from also taking credit for it. A loss is added back for the mirror reason: it already dragged net income down once, and adding it back here stops operating cash flow from being penalized twice for the same sale.

Common mistake: a gain on sale is operating cash

A gain on sale is an accounting result, not cash by itself. The cash the company actually received is the full sale price, and that entire amount goes in investing activities. The gain is subtracted from net income in operating activities only to cancel out the extra profit already sitting there, not because the gain is a cash outflow.

Every adjustment you just learned reconciles net income to a single number: net cash provided by (or used in) operating activities. Where that cash went next, buying equipment, borrowing money, paying it back, is what the investing and financing sections answer.

Pause and work

Harbor Music Lessons had a gain on sale and working-capital accounts moving in every direction, asset up, asset down, liability up, liability down, so it's a good first full pass through the sign rule.

Foothill Fitness Coaching had a loss instead of a gain. Fill in how the loss and two of the working-capital lines get treated, then finish the total.

Now build the whole operating section from scratch for a new company.
