Brand power: Coca-Cola's intangible asset

Buffett's 1988 Coca-Cola purchase is usually told as a story about a famous brand. The more useful reading is that he was buying a distribution and habit system that a competitor could not rebuild at any price, with the brand acting as its most visible component. This lesson separates brand as marketing from brand as an economic moat — a distinction that determines whether the asset shows up in the numbers.

Key concepts

Economic moat: A structural feature that lets a business sustain returns on capital above its cost of capital for a long period while competitors try to compete them away. The test is durability of excess returns, not popularity.
Pricing power: The ability to raise prices roughly with or above inflation without losing volume. It is the single most visible financial fingerprint of a moat, and Buffett has called the need to hold a prayer session before raising prices the sign of a terrible business.
Mental availability: The product being the automatic answer in a purchase moment. Coca-Cola's advantage is less that people prefer it in blind tests — famously they often do not — than that it is present, expected and requires no decision.
The billion-dollar test: Buffett's stated check: could a competitor with a billion dollars and excellent management take meaningful share? For Coca-Cola the answer involves reproducing a century of distribution agreements and universal recognition, which capital alone does not buy.

Brand is the visible tip of a distribution system

The economics of Coca-Cola depend on the drink being available in millions of outlets, cold, at a price low enough to be an unconsidered purchase. That physical network is the barrier; the brand is what makes retailers stock it and consumers reach for it without deliberation. A new entrant with a superior formula must solve availability, shelf economics and habit simultaneously — which is why challengers historically compete on price and margin rather than displacing the incumbent.

Reading the moat in the accounts

Three financial signatures tend to accompany a genuine brand moat: gross margins that are high and stable across cycles, returns on tangible capital that are unusually high because the asset is intangible, and price increases that do not depress volume. When any of the three starts drifting for several consecutive periods without a clear one-off cause, the moat is narrowing regardless of how strong the brand still feels.

How brand moats actually erode

Rarely through a direct competitor. More often through a change in the purchase moment — a shift in distribution channel, a change in what the category means to a new cohort, or a health or regulatory reframing. That is the pattern behind pressure on carbonated soft drinks, and it is why Buffett's moat question is always about what the customer's situation will look like in a decade, not about brand surveys today.

How this connects to Warren Buffett

The moat question is Buffett's second filter, applied only after the business clears the circle of competence. It also explains the shift Munger pushed him toward: paying a fair price for durable excess returns rather than a low price for assets.
