How do you modify the dividend discount model to account for companies that return cash primarily through share repurchases?

The traditional DDM systematically undervalues companies that prefer buybacks because it ignores a major cash return channel. The **total payout model** solves this by including all cash returned to shareholders. **The Problem with Traditional DDM** Consider a company with $5 billion in cash flow to equity that pays $1.5 billion in dividends and repurchases $3 billion in stock. The DDM values only the $1.5 billion dividend stream — ignoring 67% of the actual cash distribution. **Three Approaches to Handle Buybacks** | Model | What It Discounts | Divides By | |---|---|---| | Traditional DDM | Dividends only | Current shares | | Total Payout Model | Dividends + Buybacks | Current shares | | FCFE Model | All cash available to equity | Current shares | **The Total Payout Model** Total Payout = Dividends + Net Share Repurchases V0 = Total Payout(1) / (r - g) **Worked Example — Drummond Industries:** | Item | Traditional DDM | Total Payout Model | |---|---|---| | Dividends (Year 1) | $1,800M | $1,800M | | Net buybacks (Year 1) | — | $2,700M | | **Total distribution** | **$1,800M** | **$4,500M** | | Growth rate (g) | 4.0% | 4.0% | | Required return (r) | 10.5% | 10.5% | | **Equity value** | **$27,692M** | **$69,231M** | | Shares outstanding | 420M | 420M | | **Value per share** | **$65.93** | **$164.84** | | Current market price | $155.00 | $155.00 | | **Signal** | Overvalued | Slightly undervalued | The DDM says the stock is massively overvalued at $155. The total payout model says it is slightly undervalued. The difference is entirely due to ignoring $2.7 billion in buybacks. \`\`\`mermaid flowchart TD A["Cash Flow to Equity

If buybacks are funded by steady cash flows, the growth rate should reflect sustainable earnings growth. If buybacks are funded by one-time debt issuance, the model breaks down. **Exam Tips:** 1. The total payout model is the curriculum's recommended adjustment for buyback-heavy firms. 2. Growth rate g should be the sustainable growth in total distributions, not just dividend growth. 3. Net repurchases = gross buybacks minus new shares issued (options, RSUs). Use net to avoid overstating. 4. If total payout exceeds FCFE, the excess is financed by debt or cash drawdown — unsustainable long-term. Explore payout-adjusted valuation models in our CFA Level II equity course.
