Readers often ask how I carry out valuations. The starting point is calculating owner-earnings. Here's an extract from Berkshire-Hathaway's 1986 report, in which Warren Buffett sets out his thoughts on owner-earnings.

Warren Buffett on owner-earnings

First a short quiz: below are abbreviated 1986 statements of earnings for two companies. Which business is the more valuable?

As you've probably guessed, Companies O and N are the same business - Scott Fetzer. In the "O" (for "old") column we have shown what the company's 1986 GAAP earnings would have been if we had not purchased it; in the "N" (for "new") column we have shown Scott Fetzer's GAAP earnings as actually reported by Berkshire.

It should be emphasized that the two columns depict identical economics - i.e., the same sales, wages, taxes, etc. And both "companies" generate the same amount of cash for owners. Only the accounting is different.

So, fellow philosophers, which column presents truth? Upon which set of numbers should managers and investors focus?

Before we tackle those questions, let's look at what produces the disparity between O and N. We will simplify our discussion in some respects, but the simplification should not produce any inaccuracies in analysis or conclusions.

The contrast between O and N comes about because we paid an amount for Scott Fetzer that was different from its stated net worth. Under GAAP, such differences - such premiums or discounts - must be accounted for by "purchase-price adjustments." In Scott Fetzer's case, we paid $315 million for net assets that were carried on its books at $172.4 million. So we paid a premium of $142.6 million.

The first step in accounting for any premium paid is to adjust the carrying value of current assets to current values. In practice, this requirement usually does not affect receivables, which are routinely carried at current value, but often affects inventories. Because of a $22.9 million LIFO reserve and other accounting intricacies, Scott Fetzer's inventory account was carried at a $37.3 million discount from current value. So, making our first accounting move, we used $37.3 million of our $142.6 million premium to increase the carrying value of the inventory.

Assuming any premium is left after current assets are adjusted, the next step is to adjust fixed assets to current value. In our case, this adjustment also required a few accounting acrobatics relating to deferred taxes. Since this has been billed as a simplified discussion, I will skip the details and give you the bottom line: $68.0 million was added to fixed assets and $13.0 million was eliminated from deferred tax liabilities. After making this $81.0 million adjustment, we were left with $24.3 million of premium to allocate.

Had our situation called for them two steps would next have been required: the adjustment of intangible assets other than Goodwill to current fair values, and the restatement of liabilities to current fair values, a requirement that typically affects only long-term debt and unfunded pension liabilities. In Scott Fetzer's case, however, neither of these steps was necessary.

The final accounting adjustment we needed to make, after recording fair market values for all assets and liabilities, was the assignment of the residual premium to Goodwill (technically known as "excess of cost over the fair value of net assets acquired"). This residual amounted to $24.3 million. Thus, the balance sheet of Scott Fetzer immediately before the acquisition, which is summarized below in column O, was transformed by the purchase into the balance sheet shown in column N. In real terms, both balance sheets depict the same assets and liabilities - but, as you can see, certain figures differ significantly.

The higher balance sheet figures shown in column N produce the lower income figures shown in column N of the earnings statement presented earlier. This is the result of the asset write-ups and of the fact that some of the written-up assets must be depreciated or amortized. The higher the asset figure, the higher the annual depreciation or amortization charge to earnings must be. The charges that flowed to the earnings statement because of the balance sheet write-ups were numbered in the statement of earnings shown earlier:

1. $4,979,000 for non-cash inventory costs resulting, primarily, from reductions that Scott Fetzer made in its inventories during 1986; charges of this kind are apt to be small or non-existent in future years.

2. $5,054,000 for extra depreciation attributable to the write-up of fixed assets; a charge approximating this amount will probably be made annually for 12 more years.

3. $595,000 for amortization of Goodwill; this charge will be made annually for 39 more years in a slightly larger amount because our purchase was made on January 6 and, therefore, the 1986 figure applies to only 98% of the year.

4. $998,000 for deferred-tax acrobatics that are beyond my ability to explain briefly (or perhaps even non-briefly); a charge approximating this amount will probably be made annually for 12 more years.

It is important to understand that none of these newly-created accounting costs, totaling $11.6 million, are deductible for income tax purposes. The "new" Scott Fetzer pays exactly the same tax as the "old" Scott Fetzer would have, even though the GAAP earnings of the two entities differ greatly. And, in respect to operating earnings, that would be true in the future also. However, in the unlikely event that Scott Fetzer sells one of its businesses, the tax consequences to the "old" and "new" company might differ widely.

By the end of 1986 the difference between the net worth of the "old" and "new" Scott Fetzer had been reduced from $142.6 million to $131.0 million by means of the extra $11.6 million that was charged to earnings of the new entity. As the years go by, similar charges to earnings will cause most of the premium to disappear, and the two balance sheets will converge. However, the higher land values and most of the higher inventory values that were established on the new balance sheet will remain unless land is disposed of or inventory levels are further reduced.

What does all this mean for owners? Did the shareholders of Berkshire buy a business that earned $40.2 million in 1986 or did they buy one earning $28.6 million? Were those $11.6 million of new charges a real economic cost to us? Should investors pay more for the stock of Company O than of Company N? And, if a business is worth some given multiple of earnings, was Scott Fetzer worth considerably more the day before we bought it than it was worth the following day?

If we think through these questions, we can gain some insights about what may be called "owner earnings." These represent (a) reported earnings plus (b) depreciation, depletion, amortization, and certain other non-cash charges such as Company N's items (1) and (4) less ( c) the average annual amount of capitalized expenditures for plant and equipment, etc. that the business requires to fully maintain its long-term competitive position and its unit volume. (If the business requires additional working capital to maintain its competitive position and unit volume, the increment also should be included in ( c) . However, businesses following the LIFO inventory method usually do not require additional working capital if unit volume does not change.)

Our owner-earnings equation does not yield the deceptively precise figures provided by GAAP, since( c) must be a guess - and one sometimes very difficult to make. Despite this problem, we consider the owner earnings figure, not the GAAP figure, to be the relevant item for valuation purposes - both for investors in buying stocks and for managers in buying entire businesses. We agree with Keynes's observation: "I would rather be vaguely right than precisely wrong."

The approach we have outlined produces "owner earnings" for Company O and Company N that are identical, which means valuations are also identical, just as common sense would tell you should be the case. This result is reached because the sum of (a) and (b) is the same in both columns O and N, and because( c) is necessarily the same in both cases.

And what do Charlie and I, as owners and managers, believe is the correct figure for the owner earnings of Scott Fetzer? Under current circumstances, we believe ( c) is very close to the "old" company's (b) number of $8.3 million and much below the "new" company's (b) number of $19.9 million. Therefore, we believe that owner earnings are far better depicted by the reported earnings in the O column than by those in the N column. In other words, we feel owner earnings of Scott Fetzer are considerably larger than the GAAP figures that we report.

That is obviously a happy state of affairs. But calculations of this sort usually do not provide such pleasant news. Most managers probably will acknowledge that they need to spend something more than (b) on their businesses over the longer term just to hold their ground in terms of both unit volume and competitive position. When this imperative exists - that is, when ( c) exceeds (b) - GAAP earnings overstate owner earnings. Frequently this overstatement is substantial. The oil industry has in recent years provided a conspicuous example of this phenomenon. Had most major oil companies spent only (b) each year, they would have guaranteed their shrinkage in real terms.

All of this points up the absurdity of the "cash flow" numbers that are often set forth in Wall Street reports. These numbers routinely include (a) plus (b) - but do not subtract ( c) . Most sales brochures of investment bankers also feature deceptive presentations of this kind. These imply that the business being offered is the commercial counterpart of the Pyramids - forever state-of-the-art, never needing to be replaced, improved or refurbished. Indeed, if all U.S. corporations were to be offered simultaneously for sale through our leading investment bankers - and if the sales brochures describing them were to be believed - governmental projections of national plant and equipment spending would have to be slashed by 90%.

"Cash Flow", true, may serve as a shorthand of some utility in descriptions of certain real estate businesses or other enterprises that make huge initial outlays and only tiny outlays thereafter. A company whose only holding is a bridge or an extremely long-lived gas field would be an example. But "cash flow" is meaningless in such businesses as manufacturing, retailing, extractive companies, and utilities because, for them, ( c) is always significant. To be sure, businesses of this kind may in a given year be able to defer capital spending. But over a five- or ten-year period, they must make the investment - or the business decays.

Why, then, are "cash flow" numbers so popular today? In answer, we confess our cynicism: we believe these numbers are frequently used by marketers of businesses and securities in attempts to justify the unjustifiable (and thereby to sell what should be the unsalable). When (a) - that is, GAAP earnings - looks by itself inadequate to service debt of a junk bond or justify a foolish stock price, how convenient it becomes for salesmen to focus on (a) + (b). But you shouldn't add (b) without subtracting ( c) : though dentists correctly claim that if you ignore your teeth they'll go away, the same is not true for ( c) . The company or investor believing that the debt-servicing ability or the equity valuation of an enterprise can be measured by totaling (a) and (b) while ignoring ( c) is headed for certain trouble.

* * *

To sum up: in the case of both Scott Fetzer and our other businesses, we feel that (b) on an historical-cost basis - i.e., with both amortization of intangibles and other purchase-price adjustments excluded - is quite close in amount to ( c) . (The two items are not identical, of course. For example, at See's we annually make capitalized expenditures that exceed depreciation by $500,000 to $1 million, simply to hold our ground competitively.) Our conviction about this point is the reason we show our amortization and other purchase-price adjustment items separately in the table on page 8 and is also our reason for viewing the earnings of the individual businesses as reported there as much more closely approximating owner earnings than the GAAP figures.

Questioning GAAP figures may seem impious to some. After all, what are we paying the accountants for if it is not to deliver us the "truth" about our business. But the accountants' job is to record, not to evaluate. The evaluation job falls to investors and managers.

Accounting numbers, of course, are the language of business and as such are of enormous help to anyone evaluating the worth of a business and tracking its progress. Charlie and I would be lost without these numbers: they invariably are the starting point for us in evaluating our own businesses and those of others. Managers and owners need to remember, however, that accounting is but an aid to business thinking, never a substitute for it.
