The second half of Chapter 6 is where payout policy stops being about dates and forms and starts being about numbers. The big questions: what do buybacks do to EPS and book value? And are dividends and repurchases really the same thing for shareholders?

What buybacks do to the balance sheet

A share repurchase financed with cash cuts both assets and shareholders’ equity. Leverage goes up. If the company borrows to fund the buyback, leverage jumps even more.

Fewer shares outstanding can raise EPS if net income holds steady. That is why CFOs and analysts love talking about buybacks. But the book is careful: a higher EPS does not automatically mean higher shareholder wealth.

EPS: cash vs. debt financing

Idle cash example (Takemiya Industries): 10 million shares, ¥100 million net income, EPS = ¥10. Surplus cash of ¥240 million buys back shares at ¥140 (¥20 above market). About 1.7 million shares retire. New EPS ≈ ¥12. A 20% bump. The cash was earning near zero anyway, so keeping it inside the company was not adding value.

Debt-financed example (Jensen Farms): EPS before buyback = $3. Share price = $60. Earnings yield (E/P) = 5%. After-tax borrowing cost = 5%. Buy back 200,000 shares with $12 million of debt. Net income falls by after-tax interest. EPS stays at $3. Break-even.

Push the after-tax borrowing rate to 6%. EPS falls. The rule: buybacks financed with debt help EPS only when the earnings yield beats the after-tax cost of debt. Internal financing helps only when the repurchased cash would not earn its cost of capital if kept in the business.

Do not confuse EPS with value. The same idle cash could have been paid as a dividend. The EPS pop from a buyback can come at the expense of dividend yield. Higher EPS from fewer shares is not free money.

Book value per share: it depends on price vs. book

Company A: market price $20, book value $10 per share. Company B: market price $20, book value $30 per share. Both buy back 250,000 shares at $20 for $5 million.

• Company A (price > book): BVPS falls from $10.00 to $9.74.
• Company B (price < book): BVPS rises from $30.00 to $30.26.

Buy back above book, BVPS drops. Buy back below book, BVPS rises. Simple but easy to forget when people cite price-to-book ratios after a buyback.

Dividends and buybacks: equivalent in a perfect world

Waynesboro Chemical has 10 million shares at $20 and $50 million of free cash flow to distribute.

Cash dividend option: Pay $5 per share. After ex-date, each share is worth $15. Add the $5 cash. Total wealth = $20.

Buyback option: Repurchase 2.5 million shares at $20. Remaining 7.5 million shares still worth $20 each. Total wealth = $20.

Whether you sold into the buyback or held does not matter for wealth. Cash in hand or stock at market value counts the same.

The baseline assumption: same tax treatment and same information content. In the real world, those differ. That is where Chapter 7 picks up.

When equivalence breaks: Florida Citrus wanted to buy back shares from activist Kirk Parent at $25 (a $5 premium) instead of $20 market. That would have dropped the post-buyback price to $18.75 for everyone else. Wealth transfers to Parent. Total wealth is conserved, but remaining shareholders lose $1.25 per share.

What announcements actually signal

The book closes with research and real examples. Buyback announcements tend to bring positive excess returns. Management often buys when it thinks the stock is cheap.

Dividend initiations and surprise increases also tend to bring positive returns. Healy and Palepu found earnings rose 43% in the year of dividend initiation and 164% over the next four years. Oracle’s tiny 2009 dividend ($0.05 quarterly) signaled confidence despite the recession. Eurotunnel’s first-ever dividend after restructuring said the same thing.

Dividend cuts and omissions send the opposite signal. IBM’s 1993 dividend cut of more than 50% was painful but funded a pivot away from mainframes. It worked. The company resumed increases in 1996.

The chapter summary boils down to: cash dividends and buybacks are both payouts. Stock dividends and splits are accounting reshuffles. Regular cash dividends are commitments. Buybacks are flexible. A buyback of equal size can match a dividend in wealth terms. EPS can rise, but that is not the same as creating value.

My take: The EPS section is the one I see misused most in earnings calls. “We bought back shares, so EPS grew 8%.” Okay, but did total free cash flow grow? Did the earnings yield on the stock beat the cost of the debt you used? The Waynesboro equivalence example is the mental model worth keeping. If $50 million leaves the company either way, your per-share claim on what is left should be the same. Everything after that is taxes, signaling, and who actually sells.
