Acquisitions
There are four building blocks that add value to Berkshire: (1) sizable stand-alone acquisitions; (2) bolt-on acquisitions that fit with businesses we already own; (3) internal sales growth and margin improvement at our many and varied businesses; and (4) investment earnings from our huge portfolio of stocks and bonds. In this section, we will review 2017 acquisition activity.
In our search for new stand-alone businesses, the key qualities we seek are durable competitive strengths; able and high-grade management; good returns on the net tangible assets required to operate the business; opportunities for internal growth at attractive returns; and, finally, a sensible purchase price.
That last requirement proved a barrier to virtually all deals we reviewed in 2017, as prices for decent, but far from spectacular, businesses hit an all-time high. Indeed, price seemed almost irrelevant to an army of optimistic purchasers.
Why the purchasing frenzy? In part, it’s because the CEO job self-selects for “can-do” types. If Wall Street analysts or board members urge that brand of CEO to consider possible acquisitions, it’s a bit like telling your ripening teenager to be sure to have a normal sex life.
Once a CEO hungers for a deal, he or she will never lack for forecasts that justify the purchase. Subordinates will be cheering, envisioning enlarged domains and the compensation levels that typically increase with corporate size. Investment bankers, smelling huge fees, will be applauding as well. (Don’t ask the barber whether you need a haircut.) If the historical performance of the target falls short of validating its acquisition, large “synergies” will be forecast. Spreadsheets never disappoint.
The ample availability of extraordinarily cheap debt in 2017 further fueled purchase activity. After all, even a high-priced deal will usually boost per-share earnings if it is debt-financed. At Berkshire, in contrast, we evaluate acquisitions on an all-equity basis, knowing that our taste for overall debt is very low and that to assign a large portion of our debt to any individual business would generally be fallacious (leaving aside certain exceptions, such as debt dedicated to Clayton’s lending portfolio or to the fixed-asset commitments at our regulated utilities). We also never factor in, nor do we often find, synergies.
Our aversion to leverage has dampened our returns over the years. But Charlie and I sleep well. Both of us believe it is insane to risk what you have and need in order to obtain what you don’t need. We held this view 50 years ago when we each ran an investment partnership, funded by a few friends and relatives who trusted us. We also hold it today after a million or so “partners” have joined us at Berkshire.
