Warren Buffett, in his early partnership days, referenced three buckets that he invested in:
- Control Situations
These categories are not necessarily mutually exclusive and often a general might turn into a control situation etc. No category is intrinsically more risky than another but they all contain different types of risks. He let the current markets decide which categories he would emphasize.
Generals refer to generally undervalued companies. These companies didn’t have a catalyst to realize value. This category included both high-quality companies such as the infamous American Express investment and in Disney as well as lesser known cigar-butt-style investments in generally undervalued companies like Western Insurance (technically invested in when Buffett worked for Graham-Newman). Investments such as these often allowed for greater absolute returns than in the workouts category but have higher correlation with the overall market than workouts. These were initially mostly qualitative Graham style net-nets and other similar style investments but later evolved more and more into qualitative style investments. An increase in the size of Buffett’s portfolio and a decrease in obvious shooting dead fish in a barrel investments such as net-nets also helped him to change his ways. Buffett didn’t mention many
Workouts, probably more often referred to as special situations or risk arbitrage nowadays, are situations where a return and time frame are knowable ahead of time. This can be a liquidation, merger, tender offer, spin-off or other complex transactions.
In the 1965 partnership letter Buffett described workouts as:
He had invested in numerous merger arbitrage situations, notably using quite a bit of leverage going so far as to say that, “borrowed money is appropriate in most workout situations.” One area of particular interest during his partnership years was merger arbitrage between Oil and Gas companies. It could have been a sign of the times but also it could have been related to how few holdups there are in O&G mergers. There are/were no unions, trade creditors, regulatory issues etc in any small O&G company getting bought out. Buffett would buy any of the securities of a company if so was warranted, not just the common stock. In the example of Texas National Petroleum he purchased debentures, common stock and warrants making 20%+ annualized returns.
One infamous example, (also from Buffett’s Graham-Newman days) was a split-off transaction involving Rock-wood Cocoa where one could exchange shares of stock priced at $34 for warehouse certificates for Cocoa worth $36 for a profit of $2. Graham instructed Buffett to pursue the arbitrage situation selling the certificates using the futures market. Buffett however, for his personal account, simply bought and held the shares anticipating that because so many other investors were tendering their shares that the reduced amount of shares outstanding would increase the net asset value per share dramatically. Say if Rock-Wood Cocoa had $50/share in net asset value (NAV) before the tender offer and 70% of shareholders accepted the tender offer then the NAV would jump to ~$82.
Control situations are Buffett’s main investment category these days. Back in the partnership days he saw control situations as a way to reduce risk in his portfolio. But also noted that mark to market returns of control situations could often drag behind bluechip stocks of the day.
Many people would perhaps attempt to split control situations into proper control situations and into activist situations. Buffett did a little of both. Ben Graham, Buffett’s investment hero, also did quite a bit of both.
Graham had been the major control investor in Geico, until he was forced to spin-off the company to Graham-Newman shareholders (from Graham initial purchase price to its high price during his lifetime was 605x). Graham had potentially numerous control positions but not many are well known to this day. Graham controlled a company called Philadelphia and Reading Coal & Iron company which he had used to purchase another company (later Philadelphia and Reading would be managed by Howard Newman the son of Ben Graham’s partner Jerry Newman). Graham was an activist in several Rockefeller pipeline companies. In these situations the pipeline companies often had excess investments worth more than the entire market caps of the companies. One company called Northern Pipe Line, had investments worth $95 and the stock was trading for $65. Graham tried to persuade management and when he failed to do so initiated a proxy contest. After a protracted period he was able to persuade investors even the great Rockefeller himself to vote management to distribute excess funds. Rockefeller later instructed many of his other pipe line assets and likewise companies to distribute excess funds.
A very similar situation to the Northern Pipe Line was Buffett’s investment in Sanborn Maps. The stock was selling for $45 a share but had $65 a share in investments. He eventually succeeded in having the company payout (through a tender offer) a significant portion of the cash and investments in-kind making a more than 20% per year for the two year investment.
Buffett later went on into Dempster Mills and Berkshire Hathaway as more of a builder than a liquidator. Although he did partially liquidate both companies he did not do a wholesale tear-down of either company. Dempster mills helped to change Buffett. After the Dempster Mills experience he was less interested in investing in cigar butts and more interested in great companies at fair prices. A similar experience with Carl Icahn in his investment in Dan River has never deterred him from investing in cigar butts. Buffett had control investments through many vehicles including top level vehicles of Berkshire Hathaway, Diversified Retailing Company and Blue-chip Stamps. A list of his many vehicles is as follows:
He would later simplify these vehicles into ownership under Berkshire Hathaway.
As we can see from the foregoing post Buffett’s tactics were close approximations of Ben Graham’s strategies. Even in the field of control/activist investments Buffett initially mimicked Graham. Buffett later made a few twists such as having a way less diversified portfolio as well as buying higher quality businesses.
