Notes on Reading Balance Sheets

I read balance sheets badly for several years before I read them usefully. The difference was not additional accounting knowledge. It was learning what to look for.

These are notes rather than a method. They are the questions I now ask, in roughly the order I ask them.

Start with the shape, not the numbers

Before reading any figure, look at the proportions. What fraction of assets is cash? How much of the liability side is debt versus payables? Is equity a large or small share of the total?

The shape tells you what kind of business you are looking at faster than the income statement does. A business with heavy fixed assets and long-dated debt behaves differently from one with almost no assets and large deferred revenue, regardless of what either says about itself.

The shape also tells you what could go wrong. A business funded by short-term borrowing against long-lived assets has a specific failure mode, and it does not depend on the business being badly run.

Read three years at once

A single balance sheet is a photograph. It tells you where things stand and almost nothing about direction.

Three years side by side tells you what is growing, what is shrinking, and what is being quietly reclassified. Reclassification is the interesting one. When a line item moves categories between years, there is usually a reason, and the reason is usually explained somewhere less prominent.

Most of what I have learned from financial statements came from noticing that a number moved, not from the number itself.

Follow the working capital

For most operating businesses, the working capital cycle explains more about cash generation than profit does. How long does inventory sit? How quickly do customers pay? How long does the business take to pay suppliers?

A profitable business with deteriorating working capital is consuming cash while reporting earnings. This is extremely common, entirely legal, and visible to anyone who looks. It is also the single most useful thing I know how to check.

The inverse matters too. A business that collects before it pays is being financed by its own operations, which is a genuine structural advantage and rarely described as one.

Be suspicious of the tidy number

Numbers that are suspiciously round, or suspiciously stable across periods, are worth a second look. Real operations produce messy figures. Tidiness usually means an estimate, and estimates involve judgement.

This is not an accusation of anything. Estimates are unavoidable and mostly made honestly. But an estimate is a place where the picture depends on someone’s assumption, and it is worth knowing where those places are.

The notes are the document

The statements are a summary. The notes are where the actual information lives: what is included in each line, which assumptions were used, what obligations exist that do not appear on the face of the balance sheet.

Reading only the statements and skipping the notes is like reading chapter titles. It took me an embarrassingly long time to internalise this, and it changed how much I get from an annual report more than anything else on this list.
