Each year, Warren Buffett writes an open letter to Berkshire Hathaway shareholders which many value investors can’t wait to jump on reading. In this post, we have summarised the key learnings from the letter written in 1981, to save you the time from reading the whole letter (although still strongly recommended).
Berkshire Hathaway – 1981 Letter Learnings
Buffett: In aggregate, our non-controlled business interests have more favorable underlying economic characteristics than our controlled businesses. That’s understandable; the area of choice has been far wider. Small portions of exceptionally good businesses are usually available in the securities markets at reasonable prices. But such businesses are available for purchase in their entirety only rarely, and then almost always at high prices.
MoneyWiseSmart (MWS): That’s our benefit of being (rather) small fish. Do you use it?
Buffett: For inflation acts as a gigantic corporate tapeworm. That tapeworm preemptively consumes its requisite daily diet of investment dollars regardless of the health of the host organism. Whatever the level of reported profits (even if nil), more dollars for receivables, inventory and fixed assets are continuously required by the business in order to merely match the unit volume of the previous year. The less prosperous the enterprise, the greater the proportion of available sustenance claimed by the tapeworm.
MWS: Do your companies face the imminent attack of the gigantic corporate inflation tapeworms? Are they capital-light enough to tackle them, particularly so during high inflationary periods?
Buffett: In other words, investors can always buy toads at the going price for toads. If investors instead bankroll princesses who wish to pay double for the right to kiss the toad, those kisses had better pack some real dynamite. We’ve observed many kisses but very few miracles. Nevertheless, many managerial princesses remain serenely confident about the future potency of their kisses – even after their corporate backyards are knee-deep in unresponsive toads.
In fairness, we should acknowledge that some acquisition records have been dazzling. Two major categories stand out. The first involves companies that, through design or accident, have purchased only businesses that are particularly well adapted to an inflationary environment. Such favored business must have two characteristics: (1) an ability to increase prices rather easily (even when product demand is flat and capacity is not fully utilized) without fear of significant loss of either market share or unit volume, and (2) an ability to accommodate large dollar volume increases in business (often produced more by inflation than by real growth) with only minor additional investment of capital…
The second category involves the managerial superstars – men who can recognize that rare prince who is disguised as a toad, and who have managerial abilities that enable them to peel away the disguise.
MWS: Do your management like to kiss toads? If so, do they have good track records (as good kissers)?
Buffett: While investors and managers must place their feet in the future, their memories and nervous systems often remain plugged into the past. It is much easier for investors to utilize historic p/e ratios or for managers to utilize historic business valuation yardsticks than it is for either group to rethink their premises daily. When change is slow, constant rethinking is actually undesirable; it achieves little and slows response time. But when change is great, yesterday’s assumptions can be retained only at great cost. And the pace of economic change has become breathtaking.
MWS: Do you live in the past & extrapolate, or rethink ahead?
