## What this lens optimizes for

Owning a business whose competitive position is still intact in ten years, bought
at a price where an average outcome is acceptable. Durability is ranked above
growth rate, and both are ranked above cheapness.

## Market-fit note

- Needs ten years of comparable financials. A company with three years of history
  cannot be assessed under this lens, whatever its quality.
- In A-shares and HK, the moat question is often really a *policy* question:
  licences, pricing approval, distribution control. Name the source of the moat
  precisely rather than calling it "brand".
- State-influenced pricing (utilities, telecoms, healthcare procurement) caps
  franchise economics regardless of market share — treat administered pricing as a
  ceiling on the moat, not a moat.

## Priority signals (walk in this order)

1. **Explainability.** Can the business model be stated in two sentences, including
   who pays, for what, and why they cannot easily stop? If not, the lens stops here
   — this is the circle-of-competence gate, and it is a gate, not a score.
2. **Source of the moat, named specifically.** Exactly one of: switching cost,
   network effect, intangible asset (brand or licence), cost advantage, or efficient
   scale in a small market. "Good management" and "first mover" are not moats.
3. **Moat evidence in the numbers.** Ten-year gross margin stability, pricing taken
   above input inflation, ROIC persistently above cost of capital, market share
   stable or rising *without* rising sales-and-marketing intensity. A moat that does
   not show up in margins or returns is a story.
4. **Moat direction.** Widening, flat, or narrowing — with the specific evidence.
   A narrowing moat at a low multiple is the classic trap this lens is meant to
   avoid.
5. **Owner earnings, not reported earnings.** Net income, plus depreciation and
   amortization, minus the capital expenditure genuinely required to hold the
   current competitive position. Separate maintenance capex from growth capex
   explicitly; if the split cannot be estimated, say so and widen the value range.
6. **Capital allocation record.** What management did with a decade of retained
   earnings: incremental return on retained capital, acquisition track record,
   buybacks executed above or below intrinsic value, dilution history.
7. **Price against a value range.** Value the owner-earnings stream under
   conservative, base and optimistic assumptions. The margin of safety is the
   discount to the *conservative* case, not the base case.

## Disqualifiers (hard vetoes)

- **Business not explainable in two sentences** — outside the circle of competence.
- **Moat cannot be named as a specific mechanism**, or the named mechanism is
  contradicted by margin and share trends.
- **Owner earnings persistently below reported net income** across a full cycle:
  the earnings are accounting, not cash.
- **Capital-intensive growth that does not raise returns** — capex rising, ROIC
  flat or falling. Growth here destroys value.
- **Management demonstrably not shareholder-aligned** — serial dilution at
  depressed prices, related-party transfers, repeated restatements.
- **Only the optimistic case clears the price.** No margin of safety means no
  position under this lens, regardless of business quality.

## Scoring rubric

| Gate | Pass condition |
| --- | --- |
| Understandable | Two-sentence model, stated |
| Moat named | One specific mechanism, with margin/share/ROIC corroboration |
| Moat direction | Not narrowing |
| Owner earnings | Positive, cash-backed, ≥ reported net income across the cycle |
| Capital allocation | Incremental ROIC on retained earnings above cost of capital |
| Price | Discount to the conservative-case value, stated in % |

Any gate failing ends the run. There is no compensating high score.

## Typical misuse

- **Applied to fast-changing technology.** The ten-year durability question cannot
  be answered where the competitive basis resets every product cycle; the lens will
  either refuse everything or manufacture false confidence.
- **Applied to deep cyclicals.** Peak-cycle earnings look like franchise economics.
  Trough-cycle earnings look like moat erosion. Use a cycle lens to set the
  normalized earnings level first.
- **Moat asserted from market share alone.** Share bought with promotion spending
  is the opposite of a moat; check whether margins held while share rose.
- **Quality used to excuse any price.** "Wonderful business" is a reason to accept
  a fair price, not an unbounded one. If the multiple assumes decades of the current
  growth rate, the durability judgement is doing work it cannot support.
- **Maintenance capex guessed conveniently.** Understating it turns almost any
  capital-intensive business into a cash machine. If it is a guess, the valuation
  range must widen accordingly.
- **Retroactive moat.** Explaining historical returns by inventing a moat after the
  fact. The mechanism must predict something, not just describe the past.

## Falsifiers

- Gross margin compresses for two consecutive years while volumes hold → pricing
  power is gone, and the moat premise fails regardless of share.
- A new entrant reaches meaningful share without matching the incumbent's cost base
  → the cost advantage was scale-dependent and is now contestable.
- Incremental ROIC on the last five years of retained earnings falls below cost of
  capital → the compounding assumption in the valuation is void.

## Output contract

Report under the skill-level output contract. State the verdict as "under a
quality-franchise framework, …", name the moat mechanism explicitly, and give the
maintenance-vs-growth capex split you assumed. This is analysis, not investment
advice.
