Zero-Coupon Bonds

Origin: 1989 Letter Category: Tactical & Accounting

📖 Definition

A Zero-Coupon Bond is a debt security that does not pay periodic interest. Instead, it is issued at a deep discount to its face value, and the investor's return is the difference between the purchase price and the maturity value.

🧠 Benign vs. Malign Variations

In the 1989 Letter, Buffett distinguishes between two types of zero-coupon instruments:

1. Benign Variations

  • Series E Savings Bonds: Simple, retail-friendly government bonds.
  • Stripped Treasuries: Created by investment bankers to solve "reinvestment risk" for long-term investors like pension funds.
  • Quote: "Nobody, of course, called the Series E a zero-coupon bond... But that's precisely what the Series E was."

2. Malign Variations (The "Mischief")

  • Junk/PIK Bonds: High-yield bonds issued by shaky companies that pay interest in more bonds (Pay-In-Kind) or defer it entirely for years.
  • Delayed Default: Buffett notes that it is "impossible to default on a promise to pay nothing." These instruments allow promoters to delay the consequences of foolish deals for years, collecting fees while "chickens" wait to come home to roost.
  • Accounting Nonsense: These bonds often allow companies to create "income" for bondholders without experiencing the "pain" of current cash expenditure.

🏛️ Bartender Morality

Buffett critiques the role of investment bankers in these deals, suggesting they should have the morality of a "responsible bartender" who refuses the next drink to a drunk to prevent a disaster.

  • Quote: "In recent years, unfortunately, many leading investment firms have found bartender morality to be an intolerably restrictive standard."

🔄 Berkshire's Own Zero-Coupon Issue

In 1989, Berkshire issued $400 million of its own zero-coupon convertible debentures.

  • Key Difference: Berkshire’s credit was rock-solid, and the deal was structured to provide a tax-efficient "interest-free loan" through the tax deductibility of the 5.5% annual accrual.

Neither our bonds nor those of certain other companies that issued similar bonds last year (notably Loews and Motorola) resemble the great bulk of zero-coupon bonds that have been issued in recent years. Of these, Charlie and I have been, and will continue to be, outspoken critics. As I will later explain, such bonds have often been used in the most deceptive of ways and with deadly consequences to investors. But before we tackle that subject, let’s travel back to Eden, to a time when the apple had not yet been bitten. If you’re my age you bought your first zero-coupon bonds during World War II, by purchasing the famous Series E U. S. Savings Bond, the most widely-sold bond issue in history. (After the war, these bonds were held by one out of two U. S. households.) Nobody, of course, called the Series E a zero-coupon bond, a term in fact that I doubt had been invented. But that’s precisely what the Series E was.
