Goodwill, more plug than asset

17 December, 2012

There is no asset on a company’s balance sheet that wreaks more havoc on valuation and good sense than goodwill. The first problem with goodwill is that it sounds good, and when something sounds good, people feel the urge to pay for it. The second problem is that, notwithstanding claims to the contrary, it is not an asset but a plug variable that measures everything and nothing at the same time.

A short history of acquisition accounting

To understand the treatment of goodwill in GAAP, it is worth taking a quick look at how acquisitions have been accounted for over time, at least in the United States. Until a decade ago, companies that acquired other companies could pick one of two approaches to “account” for the acquisition.

  • In the first, termed pooling, the acquiring firm was allowed to incorporate just the book value of the target firm’s assets into its balance sheet, and essentially ignore or hide the premium paid over this book value. Thus, there was no goodwill on the balance sheet, but to qualify for pooling, the acquiring firm was required to jump through hoops (some of which were very expensive); for instance, only acquisitions financed entirely with stock qualified for pooling. 
  • In the second, purchase accounting, the acquiring firm had to incorporate the market value of what it paid for the target firm on its balance sheet, and to show the difference between the market value and the book value as “goodwill” on its balance sheet. Under this old system, goodwill was amortized over a fixed period not to exceed 40 years, though this amortization was not tax deductible (at least in the United States).

In spite of the fact that goodwill was a purely accounting variable and that its “non tax deductibility” made it irrelevant for cash flows, the fear of the earnings hit from amortization led companies to go through contortions (and to pay more) to qualify for pooling. AT&T, for instance, paid an additional $325 million when it bought NCR, to qualify for pooling, making an awful deal even worse. The prevalence of two different acquisition accounting systems also made it difficult to compare the balance sheet numbers for acquisitive companies that used purchase as opposed to pooling. Finally, amortizing goodwill over 40 years for all acquirers essentially resulted in both good and bad acquisitions being treated the same way for accounting purposes.

To remedy these problems, the accounting rules were changed on June 30, 2001, with four key modifications. First, pooling was disallowed and all firms were required to use purchase accounting. Second, accounting rules were changed to give accountants more discretion, albeit within strict limits, to do a reassessment of the value of a target firm’s existing assets at the time of the acquisition. To the extent that a target firm had assets on its books that were recorded at below (or above) their “fair” value today, this accounting adjustment could lead to an adjusted book value (which is different from the actual book value). In addition, accountants were also allowed some leeway to bring in the values of “intangible assets” such as customer lists and technology patents into the book value of the target firm. Third, the goodwill was then computed to be the difference between the market value paid for the target company and the “adjusted” book value. Finally, rather than amortize this goodwill over 40 years, accountants were required to revalue the acquired company at regular intervals and impair the goodwill, if they felt that the target company had declined in value.

While these changes made sense at an intuitive level, there are two things worth emphasizing about them. First, for better or worse, it has been a lucrative jobs program for accountants & appraisers, since their services are now required both at the time of the acquisition (to reappraise the value of the existing assets) and each period thereafter (to assess target company values). Second, as is the case with most accounting rules, the rules have obscured the principles of what the changes were meant to accomplish: create more transparency for investors about acquisition costs and more accountability for bad acquisitions.

So, what does goodwill measure?

If goodwill is the difference between what an acquiring company pays and the “adjusted” value of its existing assets, what exactly goes into it? To answer that question, let me compare two visions of balance sheets:


The balance sheet to the top is a conventional accounting balance sheet, with book values recorded based on what was originally paid for the existing assets, net of depreciation and debt & equity, reflecting the company’s history. The balance sheet at the bottom is a intrinsic value balance sheet, with assets broken down into investments already made and growth investments (based upon expectations for the future).

Within this framework, here is what happens after an acquisition. The accountants are called in to reestimate the value of the existing assets and replace the conventional accounting book value with the estimated value. Goodwill then becomes the difference between the price paid by the acquiring company and the reassessed value for existing assets. So, what else goes into the price that an acquirer may pay, besides the value of the existing assets? Here is my attempt to break it down:

Thus, accounting goodwill is composed of both goodwill that has a rational basis (a fair value of growth assets, control, synergy) and goodwill that is built on sand. Why should you care? As a stockholder in the acquiring firm, you first want to separate out overpayment from the remaining reasons, since it is an immediate transfer of your wealth to the target company. You could, of course, wait for accountants to impair this portion of the goodwill but it not only happens too late to help investors, but it may also reflect unexpected disappointments on control, synergy and growth assets.

I have a simple proposal that I know has zero chance of being adopted that may give investors at least a heads up, with acquiring companies. At the time of the acquisition, I noted in an earlier post that the acquiring company’s stock price drops in about 55% of acquisitions. If you accept the argument that this is the market’s collective judgment of how much was overpaid, why not break goodwill down into two components: the “market correction” can be called foolhardy goodwill and the rest can be rational goodwill. Thus, if a company pays $12 billion for a company with an adjusted book value of $ 4 billion, and sees its market cap drop by $ 3 billion on the announcement, you should see $ 3 billion in foolhardy goodwill and $ 5 billion in rational goodwill on its balance sheet. While both types of goodwill may turn out to be wrong, in hindsight, and may need to be impaired, I would argue that firms (their top managers and bankers) should be held much more accountable for failures on the former, because they chose to do the acquisition in the face of investor opposition.

The Goodwill Games: The Bottom Line

  • There is no correlation, positive or negative, between the magnitude of goodwill and the quality of a deal: Given the time and resources that accountants bring to the measurement and subsequent impairment of goodwill, you would think that their actions have substantial impacts on markets. In an accounting world, you should expect to see a differentiation across acquiring companies, based upon how much goodwill is created at the time of the deal. Presumably, if you accept the accounting interpretation of goodwill, deals that result in less goodwill should be better than deals that create more, with “better” measured as market reaction to the announcement of the deal or as performance after. As far as I know, I do not know of a single study that finds a correlation between the two. (If you do find any, please let me know….)
  • The presence of goodwill on the balance sheets of acquiring firms make it difficult to compare these firms to those that don’t do acquisitions, because it exposes the inconsistency in accounting rules on the treatment of growth assets. A growth firm that grows entirely through internal investments will not show its growth assets on its balance sheet, until it makes those investments. If that growth firm is acquired by another firm, the goodwill that shows up on the company’s balance sheets will include growth assets. Investors therefore have to wrestle with what to do about goodwill in both relative and DCF valuation: (a) If you use earnings multiples (PE, for instance) or book value multiples (Price to Book, EV to Invested Capital), comparing acquisitive firms to non-acquisitive firms can be skewed by the presence of goodwill. Since goodwill inflates the book values (of both equity and invested capital), acquisitive companies can look cheap on both price to book and EV to invested capital measures. Analysts and investors often respond by using only “tangible” book value, where goodwill is removed from the equation. (b) In discounted cash flow valuation, a key ingredient that determines value is return on equity (or return on invested capital) and both can be pushed down for acquisitive firms, if goodwill is treated as part of book capital. Analysts again respond by eliminating goodwill from book value and invested capital for accounting return measures. That may tilt the scales too far in the other direction, because it gives acquiring companies a free pass on acquisitions and makes them look better than they really are in terms on returns on invested capital. I would argue for an intermediate solution, where the foolhardy goodwill (see above) is left in invested capital and the control/synergy portions are phased in over a 3-5 year period. Firms that consistently over pay for acquisitions or fail to deliver on synergy or control will therefore be assigned lower returns on invested capital and lower value.
  • The impairment of goodwill does have an effect on stock prices but it may have also damaged earnings quality. Since for an accounting impairment assessment, there is an open question as to whether the impairment is a surprise to investors. Looking at the studies over the last decade, there is evidence that even though goodwill impairment lags economic impairment by many years, stock prices still drop on the impairment of goodwill, with the price impact of goodwill impairment being greatest at small firms that have little analyst following. However, there are also many who contend that goodwill impairments have contributed to making earnings reports more difficult to decipher and thus reduced earnings quality. Finally, there is also evidence that the initial market reaction to the acquisition is a good predictor of the subsequent impairment of goodwill. Perhaps, my proposal to separate goodwill into foolhardy and rational goodwill is not so outlandish, after all…

In summary, then, the new rules on goodwill have not reduced the propensity of acquirers to overpay for target firms, have not made their financial statements more informative, and might have made it more difficult for investors to value serial acquirers. So, would it not make more sense to move back to a simpler, automated system for reporting on acquisitions, with less accounting judgment and more reporting of facts?

Great Article Aswath. I think objective of article was to help investors/shareholders look though more clearly through goodwill. In this case, I would prefer to value acquired business separately and compare how much value was paid by Management. If acquired business is being valued significant lower (for a reasonably long time) than the value paid by management than clearly management has been wasting money, time and resources of organization and management should be held accountable explicitly (fired by Board) or implicitly (lowering of share price).
