Blue Chip Stamps
Company Overview
Blue Chip Stamps was a California trading-stamp company — retailers issued its stamps to customers at the point of sale, and customers pasted them into books and redeemed them for merchandise — that became, in the 1960s and 1970s, the unlikely vehicle through which Warren Buffett and Charlie Munger first practiced joint capital allocation at scale. Buffett's partnership became the largest shareholder; Munger became the second largest; and through Blue Chip they acquired See's Candies in 1972 and the Buffalo Evening News in 1977, before the company merged into Berkshire Hathaway in 1983.
Blue Chip had itself been born of regulation — created by a consortium of California retailers after an antitrust consent decree restructured the trading-stamp industry, with shares distributed broadly to the retailers who used the service. That origin mattered twice over: the shareholder base was diffuse and unsentimental, so control could be accumulated by outside investors who understood the asset; and the company's central accounting problem — estimating how many issued stamps would ever be redeemed, and at what cost — was genuine actuarial work that the letters discuss with unusual openness.
The trading-stamp business had one property that made it precious to two investors who thought about little else: float. Stamps were issued to shoppers continuously but redeemed slowly, and a meaningful fraction were never redeemed at all. The cash collected from retailers in advance of redemption accumulated into a large, stable, investable pool — economically identical to an insurance company's unearned premiums. Blue Chip's stamp business itself was in terminal decline by the time Munger and Buffett controlled it, but the float thrown off by decades of past issuance was very much alive. The pair's insight was to treat the declining stamp operation as a capital source and to redeploy that capital into businesses with far better economics.
Investment Story
Munger's Own Words
"It's hard for us not to love brands, since we were lucky enough to buy See's candy for $20 million as our first acquisition. We found out fairly quickly that we could raise the price every year 10%, and nobody cared. We didn't make the volumes go up or anything like that. Just made the profits go up. We've been raising the price by 10% a year for all these 40 years or so. It's been a very satisfactory company. It didn't require any new capital. That's what was good about it: very little new capital."
"In our trading stamp business our 'float' — resulting from past issuances of trading stamps when volume was many times greater than the current level — is large in relation to current issuances and is declining. Eventually, unless stamp issuances improve, earnings from investing 'float' will decline greatly."
Investment Lessons
Float exists wherever customers pay before receiving. The trading-stamp industry was dying, and its float was still worth controlling a company for. Munger's generalization — that any business collecting cash long before delivering the product or service has an investable loan from its customers — became one of the central valuation tools of the partnership, applied later to insurance premiums, subscription revenue, and deferred service income.
A declining business can be a good investment if its capital is reallocated well. Blue Chip's stamp revenues fell every year Munger wrote about them, and the investment was still a triumph, because the declining business funded See's, the Buffalo News, and Wesco. The relevant measure of a melting ice cube is not the ice cube but the skill of the person spending the melt water.
Concentrated illiquid holdings teach the difference between quotation and value. Losing 31.9% and 31.5% in consecutive years while believing the underlying assets were sound was the making of Munger's market temperament. Investors who have survived one such episode with their analysis intact behave differently in every subsequent panic.
Corporate structure should serve capital allocation, not history. The 1983 merger sacrificed Blue Chip's separate identity to simplify the ownership chain and eliminate structural inefficiency. Munger's willingness to dissolve the vehicle through which he had learned so much is the same discipline he applied to Mutual Savings: entities are tools, not monuments.
Reserving honesty is the same virtue in every industry. Estimating stamp redemption liability and estimating insurance loss reserves are the same actuarial temptation: the estimate that flatters this year's income is always available. Blue Chip's letters treat the difficulty openly, year after year, rather than hiding it in footnotes — the disclosure habit that later made Wesco's insurance reporting trustworthy.
