1. 006What areas of competitive advantage does this company have? Does it have barriers to entry, and can it sustain its revenue growth?Company analysisIntermediatecase studyMorningstarEquity Research · Chicago · 2023

   Say this

   Test the moat against the numbers rather than asserting it. A real competitive advantage shows up as returns on invested capital above the cost of capital, sustained for years, with stable or rising market share.

   Then walk it

   1. Name the source, and be specific. Intangibles like brand and patents, switching costs, network effects, cost advantage from scale or process, and efficient scale in a market too small for two players. Those five cover almost everything.
   2. Then prove it with evidence: ROIC consistently above WACC, gross margin stable through a downturn, pricing taken above inflation without volume loss, and customer retention.
   3. Then test durability directly. Ask what a well-funded competitor would have to do to take a customer, and how long it would take. If the answer is 'offer a lower price', there is no moat.
   4. On sustaining growth, separate the sources: price, volume, mix, new products, new geographies, and acquisitions. Growth from price and mix is high quality; growth from acquisitions is bought and should be valued differently.
   5. Then the honest test for a research note: is the moat widening, stable or narrowing? Morningstar's own framework is built on exactly that trend judgement, and it drives the fair value estimate far more than this year's earnings.

   Where candidates lose it

   Listing Porter's five forces as a memorised frame with no company-specific evidence. The grader wants the link from the qualitative claim to a number in the financials. No ROIC, no moat.

   Expect next

   • Is the moat widening or narrowing?
   • What return on capital does it earn against its cost of capital?
   • Would you rather own a low quality business at a great price or a high quality one at an okay price?

2. 047What does return on invested capital tell you, and how do you calculate it?Company analysisIntermediatetechnicalLong-only asset management

   Say this

   It measures how much operating profit the business generates per dollar of capital employed. Compared against the cost of capital, it tells you whether growth creates or destroys value. NOPAT divided by invested capital.

   Then walk it

   1. NOPAT is EBIT times one minus the tax rate. Invested capital is debt plus equity less cash, or equivalently net working capital plus net fixed assets plus acquired intangibles.
   2. The comparison that matters is ROIC against WACC. Above it, every dollar reinvested creates value. Below it, growth actively destroys value, which is why some growing companies should shrink.
   3. Decompose it like DuPont: ROIC is NOPAT margin times capital turnover. That tells you whether the return comes from pricing power or from asset efficiency, which are different business models with different vulnerabilities.
   4. Look at incremental ROIC, not just the average. What did the last three years of capital spending earn? A high average with a low incremental return means the good business is mature and the new spending is not working.
   5. The practical adjustments: capitalise operating leases, consider capitalising R&D for a research-heavy company, and decide how to treat goodwill. Including goodwill measures the return to shareholders including what was paid for acquisitions; excluding it measures operating quality.
   6. And be consistent across the comp set, because the adjustments swing the number enough to change the ranking.

   Where candidates lose it

   Reciting the formula without the ROIC-versus-WACC comparison. That comparison is the entire analytical content, and the incremental version is what distinguishes a serious answer.

   Expect next

   • What is the incremental ROIC?
   • Should a company earning below its cost of capital keep growing?
   • How do you treat goodwill?
3. 055How would you think about a company's capital allocation priorities?Company analysisIntermediatetechnicalCenterview PartnersInvestment Banking · Menlo Park · 2026S&P GlobalDebt Capital Markets · Chicago · 2022

   Say this

   Rank the uses by return. Reinvest in the business if it earns above the cost of capital, then acquisitions if they clear the same bar with a margin for integration risk, then buybacks if the stock is below intrinsic value, then dividends.

   Then walk it

   1. Organic reinvestment should come first when incremental returns are high, because it is the lowest-risk way to compound and requires no premium.
   2. Acquisitions next, but with a higher bar, because you pay a control premium and take integration risk. A company that habitually acquires at multiples above its own is usually transferring value to sellers.
   3. Buybacks only when the shares trade below intrinsic value. A buyback at a high price destroys value even though it raises EPS, which is why the EPS-driven buyback is such a common error.
   4. Dividends when the business generates more cash than it can reinvest well. A dividend is a signal that management is disciplined, and it is sticky, so it is a commitment.
   5. Debt paydown belongs in the ranking too, and rises to the top when leverage threatens flexibility or the rating.
   6. The signal to read: a company issuing stock at low valuations and buying back at high ones has management that does not think about value. That pattern, visible in the cash flow statement over ten years, tells you more than any strategy presentation.

   Where candidates lose it

   Treating buybacks as automatically shareholder-friendly. Price matters, and the discipline test is whether they bought back more when the stock was cheap or when the cash happened to be there.

   Expect next

   • When is a buyback value-destructive?
   • What are the different ways to use excess cash?
   • How do you judge their acquisition record?
