The Balance Sheet

The identity, and why equity is the plug

Assets equal liabilities plus equity. This is not a rule imposed on the numbers; it is what the numbers are, and it is worth understanding why. Every transaction is recorded twice: buy inventory on credit and inventory rises while payables rise; earn a profit and either cash or receivables rise while equity rises through retained earnings. The statement therefore always balances, and if it does not, something has been recorded wrongly rather than revealed by the identity. The consequence is that equity is never chosen. It is the difference between everything the company owns and everything it owes, which is why it can be negative — and a negative equity is not an accounting error but a description: the claims ahead of the shares exceed the assets, so the shares are a claim on a shortfall. Banks and heavily levered companies operate with modest equity by design. The asset side is ordered by liquidity, from cash to property, and the ordering is a statement about certainty as well. Cash is cash; receivables are promises with a collection experience behind them; inventory is a cost waiting to become a sale; property is a cost spread over decades. The further down the list, the more the number depends on an assumption — and goodwill and intangibles, which have no physical form at all, are the ones most likely to be revised. The balance sheet in one column — Current assets — cash, receivables, inventory, other: $2,000m · Non-current assets — property, intangibles, other: $3,800m · Total assets: $5,800m · Current liabilities — payables, accruals, short-term debt: $1,000m · Non-current liabilities — debt and other: $2,080m · Equity, derived from the identity: $2,720m ← Book value is not a floor. For an asset-light business most of the value never appears on the statement at all, and for a declining one the book value of plant can be far above what anyone would pay for it.

The ratios a lender reads first

Working capital is current assets minus current liabilities: the cash tied up in running the business, and the first sign of a company financing growth out of its own balance sheet. Divide instead of subtracting and you have the current ratio, which is comparable across companies in a way that dollars are not. Both answer the same question — can this business pay the bills that come due within a year — and the honest answer includes a caveat: inventory counts as a current asset only if it can be sold, and receivables only if they are collected. Net debt is total debt minus cash and equivalents, and it is the number that connects the balance sheet to the valuation lessons. If you buy the whole business you inherit the debt and you get the cash, so the price of the business is the market value of the equity plus net debt — which is why EV is the right numerator for EBITDA (F13). Net debt can be negative, and a company with more cash than debt is trading for less than the value of its operations, which happens more often than the textbooks suggest. Debt to equity measures leverage, and leverage is the reason a modest business problem can become a permanent one. Equity is the cushion that absorbs losses before a lender is impaired, so a company with debt equal to 100% of equity can survive a 40% fall in asset values with the lenders intact; one at 500% cannot. Use market values where you can — a company whose shares have halved is much more levered than its book ratios say — and read the debt maturities alongside the total, because a wall of refinancing two years out is a different risk from debt due in 2040. Off-balance-sheet obligations exist, and the modern lease standard moved most of them on. Read the commitments note: purchase obligations, guarantees and joint-venture support are claims that a balance sheet has never carried.

Book value, market value, and where they meet

The balance sheet reports what things cost, adjusted for wear and for the occasional revaluation, while the market reports what the whole company trades for. Divide the price by book value per share and you have the price-to-book ratio, and its usefulness depends entirely on whether the assets on the statement resemble the assets the business actually runs on. It works for a bank, a lender or an insurer, because their assets *are* financial — loans, securities and reserves carried near what they are worth — so book equity is a fair approximation of the capital they operate with. That is why bank valuation begins with price-to-tangible-book rather than with a cash flow forecast (F14). It fails badly for an asset-light business, where the returns come from a brand, a network or a piece of software that the accountant mostly refuses to put on the statement at all, so book value is a fraction of the enterprise and the ratio reads absurdly high forever. The middle case is the one that pays: a capital-intensive business trading below book, where the assets are real but the market believes their earning power has decayed. Deciding which of those two things is true — real assets, or a value trap — is a balance-sheet question before it is a forecast. Tangible book strips out goodwill and intangibles, which is the version that matters when you ask what would be left if the business stopped earning. Compare the two figures and the difference is the goodwill inherited from whoever bought the businesses this company owns.

What the balance sheet leaves out

The identity is exact, and that exactness is a little misleading about completeness. A balance sheet records the assets and obligations the accounting rules require it to record, and those rules change. Since 2019, U.S. public companies have had to bring **operating leases onto the balance sheet** as a right-of-use asset and a matching liability, which is why retailers and airlines that looked lightly indebted now carry lease liabilities that can exceed their reported debt. The change did not create obligations; it made visible ones that had lived in the footnotes, where a careful analyst was already adding them back by hand. Other material obligations still sit outside the statement as a number. **Purchase commitments**, take-or-pay contracts, litigation contingencies that are only “reasonably possible”, pension deficits measured on assumptions, and guarantees of a subsidiary’s debt all appear in the notes rather than in the totals. None of them is hidden in any improper sense — the notes are part of the filing — but none of them is in the ratio you compute from the face of the statement either, and a lender reads the notes precisely because the ratios built from the face of the statement can be flattering without anything being misreported. There is a subtler omission on the asset side. Internally generated intangibles — a brand that was built rather than bought, a trained workforce, software developed in-house — are expensed or amortised as the money is spent and generally never appear as an asset at anything resembling their value, while an acquisition puts a large goodwill number on the statement for similar things. Two businesses with identical economics can therefore have completely different balance sheets depending on whether they grew or bought, which is exactly why book value is the right starting point for a bank and a poor one for a software company. The statement tells you what was *recorded*; the analysis is deciding what to do about what was not. • Operating leases have been on balance sheet as a right-of-use asset and liability since 2019. • Purchase commitments, guarantees and some contingencies live in the notes, not in the totals. • Internally built intangibles are generally not recorded, while bought ones become goodwill. • So two similar businesses can show very different statements depending on how they grew. A useful habit: for any balance-sheet ratio you compute, ask which obligation the company has that the ratio cannot see. Leases and purchase commitments are the two that most often change a conclusion about how much debt a business really carries.

Some assets are promises, and some are estimates

The identity makes the balance sheet look like arithmetic, and a good part of it is. But the assets on the left are not all the same kind of thing, and the differences decide how much of the statement you should take at face value. Cash is a measurement. Goodwill is an estimate. Receivables are somewhere in between, and the allowance sitting against them is a judgement the company makes about its own customers. Start with the cash line, which is narrower than it reads. Cash that is restricted — held as collateral, sitting in a jurisdiction with exchange controls, or earmarked for a specific purpose — is disclosed separately precisely because it is not available. Short-term investments may be counted alongside it while carrying duration or credit risk that makes them not quite cash. The question to ask of the line is not how much there is, but what would have to happen for the company to be able to spend it. Receivables and inventory are the working assets where estimates accumulate. A receivable is a promise to pay, and it is carried at an amount the company expects to collect, net of an allowance it sets by judgement; a rise in days outstanding relative to sales can mean growth or it can mean the allowance is behind. Inventory is carried at the lower of cost and net realisable value, which means the write-down happens when the company decides the market has fallen — so a slow-moving line and a conservative management can look identical for a quarter or two. Then the two lines that are pure residue. **Goodwill** exists because an acquisition was paid for above the fair value of the identifiable net assets, and it is not an asset in the sense of something that can be sold; it is a record of a price paid. It is tested for impairment rather than amortised, which means a bad acquisition can sit on the balance sheet for years before it is written down, and the write-down then arrives as a charge that management describes as non-cash and one-off. Intangibles bought in the same transaction are amortised on a schedule the company chose. **Deferred tax assets** are the other one: they represent tax the company expects to recover in future periods, and they are worth only what future profits make them worth — so a valuation allowance rising against them is a quiet statement about the company’s own forecast. None of this makes the balance sheet untrustworthy. It makes it a document with two kinds of content, and the reading skill is telling them apart: which lines are amounts that were counted, and which are amounts that were decided. A rough rule is that the further down the asset side you go, the more judgement is embedded — and the more the note to the accounts, rather than the face of the statement, is where the answer lives. • Cash may be restricted, and short-term investments may not be cash in substance. • Receivables carry an allowance set by judgement; the days count is the test of it. • Goodwill records a price paid rather than an asset held, and impairment arrives late. • Deferred tax assets are worth only what future profits make them worth. A useful exercise when reading any set of accounts for the first time: mark each asset line as *counted* or *decided*. The decided lines are where the earnings quality question in this subject is usually settled.
