Are Two Better than One?
“Co-CEOs are ideal in many situations, especially when the executives provide oversight of each other’s actions and have complementary skill sets,” says Stephen Ferris, a finance professor and Rogers Chair of Money, Credit and Banking at the University of Missouri’s Trulaske College of Business. Ferris has studied the efficacy of the co-CEO model and argues that it is a highly effective way of running a business. “Co-CEOs are ideal in many situations, especially when the executives provide oversight of each other’s actions and have complementary skill sets,” he explains. “It’s actually a very successful model.” From his research on more than 100 shared-governance examples, Ferris offers the following highlights:
“Job Complementarity.” Of more than 100 shared leadership structures examined in the study, Ferris found that 45 percent had what he calls “job complementarity,” while another 45 percent had “educational complementarity” (i.e. one CEO with a graduate degree in engineering and the other with an MBA or law degree). “Ninety percent of the sample had some complementarity in terms of duties and backgrounds, which allows for a much broader set of experience and ideas with which to chart a strategy or make a decision,” Ferris says.
Compensation Gap. Another interesting finding—co-CEOs earn a little less than twice what a single CEO would earn. This seems excessive, but Ferris says the expense may be worth it, given differences in the type of compensation. “Co-CEOs get a lot less incentive-type compensation, but equivalent amounts of cash compensation,” he says. “The median co-CEO team receives 35.7 percent of the options of a solitary CEO, which we interpret positively.”
The reason a single CEO’s compensation is geared to maximizing shareholder value is to incent the individual to perform. However, with co-CEOs, “There is more of a self-policing aspect in play,” Ferris says. “Each ensures the other works as hard as he or she can to boost results—hence there is less need to link pay to performance.”
Tenure. A similarity in both leadership models is tenure—a median 4.5 years for co-CEOs and a bit more than a median five years for a sole CEO. Says Ferris, “This tells me that the co-CEO model is working just as well as the CEO model; otherwise we would see a bigger disparity.”
Double the Pleasure
Aspen Insurance had been steered by co-CEOs for the past year and one-half; so when the time came for a change at the top of the ladder, the company opted for the same shared governance model.
The reason is simple—the model worked for the diversified provider of insurance and reinsurance products—with assets of $9.3 billion and more than 670 employees in eight countries. “We were becoming increasingly diverse by geography and products, and it was very hard for one person to cover all the time zones and still maintain the sort of control we wanted to see over the business,” explains Rupert Villers, co-CEO (formerly with John Cavoores). “John and I got along great, we’ve known each other a long time, we have different skill sets, and we’re both plain speakers. Sometimes people thought we were having a tremendous row, but we were just sorting things out.”
A tremendous row? Does this give pause to Mario Vitale, former CEO of insurance broker Willis North America and Villers’ new teammate? “I’ve been in shared positions before, though not as a co-CEO,” Vitale says. “If you don’t have a big ego, it can work. They key is to complement each other in terms of strengths. Rupert and I have some overlapping expertise, but a great deal of our experience is diverse—we bring different things to the table. He’ll lead on certain responsibilities and I will on others, which eases the decisionmaking process.”
Vitale believes two people may be required to run a farflung global enterprise. “The world of business is more global and complex, with more regulations and reporting requirements than ever before,” he notes. “That’s a lot of responsibility for one person.”
There is another reason why he is excited about sharing the helm. “For the first time in my career, I can go on a vacation and not take my BlackBerry,” he says. “I know Rupert can handle whatever comes up.”
The Market Values Co-CEO Structure
Performance data for 30 companies that transitioned from a traditional single-CEO leadership to a co-CEO structure shows a positive reaction from the market.
Given the relative rarity of co-CEO leadership structures, one might expect the market to view them with suspicion. Not so, says Professor Stephen Ferris of the University of Missouri, who has conducted extensive studies of the efficacy of the co-CEO model. “Our research shows that the market reacts positively and significantly to the announcement of a dual CEO appointment,” says Ferris, who crunched the numbers on 30 companies announcing such transitions to get a bead on the market’s response to a co-CEO structure. “The average abnormal announcement return—or the return after adjusting for regular market movement and the firm’s expected return, given its level of risk—after such an announcement was 2.58 percent. If the market didn’t like these arrangements or was indifferent, then the announcement returns would be zero.”
The table below presents those findings, as well as the “abnormal announcement” returns for event windows before and after the announcement. “We wanted to look at what happened if the announcement was late in the day and the market couldn’t capture the impact on that first day, as well as what happened if there had been some leakage and people knew the announcement was coming,” explains Ferris. In all cases, the impact was both positive and significant—suggesting the market generally views a co-CEO arrangement as a positive development.

Too Many Cooks
The single CEO model is the primary paradigm of corporate leadership, although co-CEO partnerships show promise. But five CEOs? Is it possible for five people to run a large, growing enterprise without shooting each other?
Mobi Wireless Management seems to think so. Launched in 2008 with five CEOs who became friends in high school, the Indianapolis-based company manages mobile accounts for clients. The company is an offshoot of another business started 10 years ago by the fearsome five—Bluefish Wireless Management. So are they still friends?
“We’re still here,” replies Scott Kraege, one of both companies’ five managing partners. “We’ve been struggling together and succeeding together for a decade, not that we don’t trip over each other. If we’re not prepared for confrontation, dialogue and debate, we’re not going to make it.”
“Make it” is what they are doing. Since 2009, revenues at Mobi have skyrocketed 600 percent, and the number of managed wireless lines grew 78 percent. Both companies together employ 130 people. The leadership team meets to discuss all strategies and plans once a week at what the CEOs call the “roundtable.” “When we first got together, it was at the house of one of us, a bachelor at the time, and he had nothing but a small, round table, so that’s what we called it,” Kraege explains. “Now we’ve got a big round table.”
At these confabs, the CEOs draw upon each other’s respective skills, sidestepping the usual power struggles and finger pointing that doom many management-by-committee structures. “Each of us has our own department we’re in charge of,” says Kraege, who heads up new business marketing. Others are responsible for IT, finance, HR and business development, although there is overlap. Most discussions end with the five CEOs in agreement on whatever decision is on the table that day.
“We’ve had some heated, knock-down, dragged-out battles,” Kraege admits, “but that’s all healthy. Everything is out in the open, everyone gets his points across, and we all end up supporting whatever we agree on.”
