In the acquisition arena, restructuring has been raised to an art form: Managements now frequently use mergers to dishonestly rearrange the value of assets and liabilities in ways that will allow them to both smooth and swell future earnings. Indeed, at deal time, major auditing firms sometimes point out the possibilities for a little accounting magic (or for a lot). Getting this push from the pulpit, first-class people will frequently stoop to third-class tactics. CEOs understandably do not find it easy to reject auditor-blessed strategies that lead to increased future “earnings".

The reality of merging is usually far different: There is indisputably an acquirer and an acquiree, and the latter has been “purchased,” no matter how the deal has been structured. If you think otherwise, just ask employees severed from their jobs which company was the conqueror and which was the conquered. You will find no confusion. So on this point the FASB is correct: In most mergers, a purchase has been made. Yes, there are some true “mergers of equals,” but they are few and far between.

From the economic standpoint of the acquiring company, the worst deal of all is a stock-for-stock acquisition. Here, a huge price is often paid without there being any step-up in the tax basis of either the stock of the acquiree or its assets. If the acquired entity is subsequently sold, its owner may owe a large capital gains tax (at a 35% or greater rate), even though the sale may truly be producing a major economic loss.

...we don’t want to read messages that a public relations department or consultant has turned out. Instead, we expect a company’s CEO to explain in his or her own words what’s happening.

The problem arising from lofty predictions is not just that they spread unwarranted optimism. Even more troublesome is the fact that they corrode CEO behavior. Over the years, Charlie and I have observed many instances in which CEOs engaged in uneconomic operating maneuvers so that they could meet earnings targets they had announced. Worse still, after exhausting all that operating acrobatics would do, they sometimes played a wide variety of accounting games to “make the numbers.” These accounting shenanigans have a way of snowballing: Once a company moves earnings from one period to another, operating shortfalls that occur thereafter require it to engage in further accounting maneuvers that must be even more “heroic.” These can turn fudging into fraud. (More money, it has been noted, has been stolen with the point of a pen than at the point of a gun.)

Errors will usually be honest, reflecting only the human tendency to take an optimistic view of one’s commitments. But the parties to derivatives also have enormous incentives to cheat in accounting for them. Those who trade derivatives are usually paid (in whole or part) on “earnings” calculated by mark-to-market accounting. But often there is no real market (think about our contract involving twins) and “mark-to-model” is utilized. This substitution can bring on large-scale mischief. As a general rule, contracts involving multiple reference items and distant settlement dates increase the opportunities for counter-parties to use fanciful assumptions. In the twins scenario, for example, the two parties to the contract might well use differing models allowing both to show substantial profits for many years. In extreme cases, mark-to-model degenerates into what I would call mark-to-myth.

I can assure you that the marking errors in the derivatives business have not been symmetrical. Almost invariably, they have favored either the trader who was eyeing a multi-million dollar bonus or the CEO who wanted to report impressive “earnings” (or both). The bonuses were paid, and the CEO profited from his options. Only much later did shareholders learn that the reported earnings were a sham.

...beware of companies displaying weak accounting. If a company still does not expense options, or if its pension assumptions are fanciful, watch out. When managements take the low road in aspects that are visible, it is likely they are following a similar path behind the scenes. There is seldom just one cockroach in the kitchen. Trumpeting EBITDA (earnings before interest, taxes, depreciation and amortization) is a particularly pernicious practice. Doing so implies that depreciation is not truly an expense, given that it is a “non-cash” charge. That’s nonsense. In truth, depreciation is a particularly unattractive expense because the cash outlay it represents is paid up front, before the asset acquired has delivered any benefits to the business. Imagine, if you will, that at the beginning of this year a company paid all of its employees for the next ten years of their service (in the way they would lay out cash for a fixed asset to be useful for ten years). In the following nine years, compensation would be a “non-cash” expense – a reduction of a prepaid compensation asset established this year. Would anyone care to argue that the recording of the expense in years two through ten would be simply a bookkeeping formality?

...unintelligible footnotes usually indicate untrustworthy management. If you can’t understand a footnote or other managerial explanation, it’s usually because the CEO doesn’t want you to. Enron’s descriptions of certain transactions still baffle me.

I know of no reporting mechanism that would come close to describing and measuring the risks in a huge and complex portfolio of derivatives. Auditors can’t audit these contracts, and regulators can’t regulate them. When I read the pages of “disclosure” in 10-Ks of companies that are entangled with these instruments, all I end up knowing is that I don’t know what is going on in their portfolios (and then I reach for some aspirin).

Fisher's Research Questions: POINT 10. How good are the company's cost analysis and accounting controls? No company is going to continue to have outstanding success for a long period of time if it cannot break down its over-all costs with sufficient accuracy and detail to show the cost of each small step in its operation.

In that 1997 letter, we wrote, “When forced to choose between optimizing the appearance of our GAAP accounting and maximizing the present value of future cash flows, we’ll take the cash flows.” Why focus on cash flows? Because a share of stock is a share of a company's future cash flows, and, as a result, cash flows more than any other single variable seem to do the best job of explaining a company's stock price over the long term.
