Reading a balance sheet in one sitting

A balance sheet is a photograph of what an organization owns, what it owes, and the residual claimed by owners — taken on a single date. The sentence that holds it together is short enough to memorize: assets equal liabilities plus equity.

Assets are resources the organization controls and expects to get some future benefit from. Cash, inventory, equipment, buildings, and money customers still owe (receivables). Liabilities are obligations: loans, unpaid suppliers, taxes not yet sent, rent still due under a lease. Equity is the plug — what would theoretically remain for owners if assets were sold and liabilities paid at the values printed on the page. Those values are accounting values, not garage-sale prices. Equity is not “what the shares are worth.” The market may price the same company at half that residual or at five times it, and the sheet will not apologize.

The sentence assets = liabilities + equity is not a finding. It is how the page is built. If it does not hold, someone has made an arithmetic error, not a discovery. Every transaction hits at least two places so the sentence survives. Buy a truck with cash and one asset goes up while another goes down. Buy it with a loan and an asset and a liability rise together. Earn a profit that stays in the business and equity rises, usually through retained earnings. Lose money and equity shrinks. You can read a great deal by asking, of any big change from last year, which other line moved to keep the sentence true.

Read down the page, then across to last year. Current assets and current liabilities come due inside about a year. Cash, receivables, and inventory on one side. Accounts payable, short-term debt, and the portion of long-term debt due soon on the other. The gap between current assets and current liabilities is working capital. If current liabilities tower over current assets, the organization may be fine — a grocer turns inventory in days and collects before it pays — or it may be borrowing time. The line items tell you which story to test. They do not tell you which story is true. A software firm with almost no inventory is not “weak” for lacking a warehouse. A manufacturer with a warehouse full of unsold goods is not “strong” for having one.

Long-lived assets are where the photograph gets most unlike cash. Property and equipment are carried at what they cost, minus depreciation, which is a schedule for spreading that cost over the years the asset is supposed to be useful. Depreciation is not money set aside in a drawer. A fully depreciated machine can still be running, and a brand-new one can be listed at a number nobody would pay. Intangible assets are rights rather than objects: patents, trademarks, software. Goodwill is the leftover when one company buys another for more than the fair value of the identifiable pieces. It is not a pile of cash and it is not a compliment. It is the premium paid, sitting on the page until something — a failed product, a shrinking market — forces the company to admit the premium was too high and write it down.
