Financial Accounting & Reporting: Profit Is an Opinion With Rules

Two corner shops sit on the same street. Last year each sold the same amount, ended with the same cash in the till and the same stock on the shelves. Their accountants, both honest and both following the rules, signed off profits of $41,000 and $64,000. Nobody lied. One accountant guessed the freezers would last six years and the other eight. One expected more late-paying customers to default. One assumed the cheaper, older stock was sold first.

That is the odd fact at the centre of financial reporting. Cash is a count; profit is a judgement. Accounting standards exist to narrow the judgement, force it into the open and make two companies comparable. They do not remove it. A person who has studied the subject keeps a quiet habit: whenever a profit figure is quoted, they ask which choices stand behind it, and how much the number would move if the choices were different.

This piece starts where Accounting (34/50) stops. You already know that assets equal liabilities plus equity and that profit is not cash. Here you learn the rules that decide when things count, how much they count for, and where the rulebook leaves room.

This describes how reporting works. It is not investment, tax or legal advice, and every company and number below is invented.

Recognition: when does a sale count?

The first question of reporting is timing. A customer pays you today for something you will deliver over two years. Is that revenue now? Or when the thing is delivered? Or each month? Under cash accounting you would say now. Under accrual accounting, which every large company must use, revenue counts when you have earned it, meaning when the customer gets what they paid for.

For decades the rules for this were a patchwork of industry-specific guidance, and similar contracts could be booked in different ways. In May 2014 the IASB issued IFRS 15 and the FASB issued Topic 606 of its Codification, with a single five-step model, in force from 2018. In plain words: find the contract; list the separate promises in it; decide the price; split the price across the promises in proportion to what each would sell for alone; and record revenue as each promise is delivered, which can be at one moment or gradually over time.

Worked: a shop sells a laptop, an installation and 24 months of support for $1,200 in one bundle. Alone they would sell for $1,000, $100 and $300, a total of $1,400, so the bundle carries a $200 discount, spread proportionally. The laptop is allocated $857, the installation $86 and the support $257. The first two are revenue on day one: $943. The support is earned $10.71 a month. Six months in, revenue is $1,007; the other $193 is a contract liability (deferred revenue), a promise to keep serving, even though the customer's cash is already in the bank.

Without JavaScript: at $1,200 and six months, revenue recognised is $1,007 and $193 sits as deferred revenue; cash received is $1,200.

This is why software and subscription companies show a liability called deferred revenue that grows when business is good, and why a firm can report modest revenue while its bank balance swells. It is also where the standards leave judgement: how to estimate a stand-alone price for something never sold alone, and when "control" has passed on a long construction contract.

From profit to cash: the statements are one machine

Accounting students are taught to see the three statements as one machine with three displays. Profit goes in at the top of the income statement. It flows into equity on the balance sheet. And the cash flow statement explains why the cash line moved, starting from profit and undoing the accruals. Almost every company uses the indirect method: begin with net income, add back expenses that did not use cash, then adjust for the money tied up or released in the day-to-day running of the business.

Say a firm earns $120 of profit, with $30 of depreciation. Customers owe $50 more than a year ago, stock is up $20 and suppliers are owed $10 more. Cash from operations is 120 + 30 − 50 − 20 + 10 = $90. The firm is $30 short of its own profit before it has bought a single machine. Spend $60 on equipment and the free cash left is $30. Growth is hungry: the faster a firm grows, the more working capital it has to fund.

Without JavaScript: with receivables up $50, stock up $20, payables up $10 and capital spending of $60, cash from operations is $90 and free cash is $30.

Standards leave small choices here that analysts must undo. IFRS lets a company show interest it paid inside operating or financing cash flows; US GAAP puts it in operating. Two firms with identical economics can therefore show different "operating cash flow", a point Financial Statement Analysis & Valuation (36/52) returns to.

Measurement is a choice: three ways to count the stock

A shop buys the same item three times at rising prices, then sells some. Which units did it sell, the cheap early ones or the dear late ones? Physically it does not matter. For the books it matters a great deal, because the cost of goods sold is subtracted from sales to get profit, and what is not sold stays on the balance sheet as inventory. There are three standard ways to assign the cost.

• FIFO (first in, first out): the oldest costs go to cost of goods sold. In rising prices that leaves the newest, highest costs on the balance sheet and gives the highest profit.
• LIFO (last in, first out): the newest costs go to cost of goods sold. In rising prices profit is lowest, and so is the tax bill where tax follows the books. IFRS (IAS 2) forbids it; US GAAP allows it, and US tax rules require a company that uses LIFO for tax to use it in its statements too.
• Weighted average: blend all costs. A middle result, and allowed under both.

Same goods, same sales, same cash, three profits. Prices that fall instead of rise reverse the order. Nothing about the stock changed; only the label on which unit left first. Analysts of US LIFO firms read the "LIFO reserve" in the notes, the gap between LIFO and FIFO inventory, to put firms on the same footing.

Without JavaScript: selling 150 units at $20 against rising costs of $10, $12 and $14, cost of goods sold is $1,600 under FIFO, $2,000 under LIFO and $1,800 under weighted average; gross profit is $1,400, $1,000 and $1,200.

Leases: the debt that used to be invisible

A retailer needs a hundred shops. It can borrow money and buy buildings, or it can rent them. Until 2019 the second route kept most of the commitment off the balance sheet: operating leases appeared only as rent in the income statement, with a note buried in the accounts. Two companies with identical shops looked very different if one owned and the other rented. Standard-setters had said for years this misled lenders and investors.

IASB issued IFRS 16 in January 2016, applying from 1 January 2019. A lessee now records a right-of-use asset and a lease liability for almost any lease over twelve months (with an exemption for low-value items). The liability is the present value of the promised payments. Each year the lessee books depreciation on the asset and interest on the liability, so the cost is front-loaded: higher in early years than a flat rent. The US standard, ASC 842, also puts leases on balance sheets from 2019, but US GAAP kept the distinction between operating and finance leases, so an operating lease still shows a single straight-line expense. The two bodies had worked jointly on the revenue standard and ended with nearly identical rules; on leases they ended with different answers.

Worked: $100 a year for ten years at 6% is worth $736 today. Year one's cost under IFRS 16 is $73.6 of depreciation plus $44.2 of interest, $117.8, against $100 of flat rent, and the total over ten years is the same $1,000. Earnings before interest, tax, depreciation and amortisation (EBITDA) rise by $100, because rent is no longer an operating expense, and the borrowing ratio jumps. Nothing about the shop changed.

Without JavaScript: at $100 a year for ten years and 6%, the lease liability is $736, net debt to EBITDA moves from 0.75 to 2.07, and year-one cost is $117.8 against $100.

Cost, value and impairment: when an asset is worth less than the books say

Assets sit on the balance sheet at cost less depreciation, called the carrying amount. That is a record, not a price. If a factory's product falls out of fashion, the carrying amount can stay high long after the cash it can earn has fallen. Accounting's brake is the impairment test: when there are signs of trouble, compare the carrying amount with what the asset can recover. If the carrying amount is higher, write it down, and the difference is a loss in the income statement. No cash leaves in that year. The loss simply admits that cash left years ago, when the asset was bought.

The two rulebooks differ. Under IFRS (IAS 36), recoverable amount is the higher of what you could sell it for after selling costs and its value in use, the present value of the cash it would earn if you kept it. Losses on assets other than goodwill can be reversed later if things improve; for goodwill never. US GAAP uses a two-step test for assets held for use: first add up the undiscounted future cash; only if that is below the carrying amount is the asset written down to fair value, and the loss is not reversed afterwards. So the same asset can be impaired under one set of rules and not the other.

Without JavaScript: with $190 of cash a year for five years, a 10% rate and a sale value of $700, IFRS finds value in use of $720 and a loss of $280; the US test finds undiscounted cash of $950, below $1,000, and a loss of $300.

That is why write-downs tend to arrive in bad years in lumps, and why they cluster at the end of an optimistic era: the assumptions about future cash are judgements, and the moment managers revise them is itself a signal. Goodwill, the premium paid when buying a company, is tested every year under IFRS and at least yearly under US GAAP, and is the classic source of enormous write-downs after takeovers.

Judgement: how much room is there in one profit number?

Put the pieces together and the reported profit is a stack of estimates. How long do the freezers last? What share of what customers owe will never arrive? How much will warranty repairs cost on goods already sold? Which development spending creates an asset worth carrying? IFRS lets a company capitalise development costs once criteria are met; US GAAP mostly requires expensing them. The standards narrow each choice and demand disclosure, then trust the preparer and the auditor to be reasonable.

The IASB's Conceptual Framework (revised March 2018) gives the guiding test: information must be relevant and a faithful representation, and the Board restored the word prudence, meaning caution when uncertain, which is not the same as deliberately understating. Critics from both sides press the point. Some say fair value measures are too soft, pointing to the years around 2008, when banks and regulators argued that marking assets to depressed markets made a crisis worse. Others reply that historical cost simply hides losses until it is too late. Neither side has won.

Without JavaScript: the cautious end of the ranges gives a profit of $413, the bold end $1,140, with cash identical at $1,400.

Hence the rule of thumb auditors and analysts share: look at the direction of the choices over time and against peers. A firm that lengthens asset lives or cuts its bad-debt allowance in the very year it would miss a target has told you something. Auditing & Assurance (36/47) is the discipline that tests whether the choices stay inside the fence.

What a graduate just sees

• Revenue is booked when a promise is kept, not when the money arrives; cash received early is a liability.
• Profit and operating cash flow are linked by changes in receivables, inventory and payables. Growth soaks up cash.
• Different inventory methods give different profits from the same goods, and rising prices make FIFO look rosier than LIFO.
• Moving a lease onto the balance sheet adds debt and EBITDA at once and changes no economics.
• A write-down is an admission that earlier cash is gone, not a payment this year.
• Every profit figure is the product of estimates. Ask which, and which way they leaned.
• IFRS and US GAAP agree on much and differ on specifics, so compare firms under the same rulebook or adjust.
• Footnotes are not small print; they are where the choices are written down.

Where it shows up next

• Managerial & Cost Accounting (36/46): the same costs, sorted for decisions inside the firm.
• Auditing & Assurance (36/47): an independent check that the judgements are reasonable and the statements follow the standards.
• Taxation (36/48): where tax rules and book rules part ways, as with LIFO and depreciation.
• Financial Statement Analysis & Valuation (36/52): turns these statements back into economics, undoing leases and accruals.
• In the world: reading a results announcement, a loan covenant that caps "debt to EBITDA", an auditor's note about "key audit matters".
