If you're an investor in consumer goods giant Unilever (NYSE: UN), odds are you followed the takeover bid from Kraft Heinz (NASDAQ: KHC) closely in 2017. Ultimately, it fell through, with Unilever's management rebutting that it was better off on its own. There was some mustard left on the face of Kraft Heinz, but major shareholder Warren Buffett claimed there was potentially a misunderstanding of the nature of the offer. It was not intended to be a hostile takeover, he said, but it could have been perceived that way by Unilever.
Nearly a year has passed, and there are no signs of reconciling differences. However, for Unilever shareholders, reflecting on the motives of the deal provides valuable insight into the company. Warren Buffett and Kraft Heinz no doubt had a list of reasons to pursue Unilever. But I expect there's one metric above all else that caught their eye.
It boils down to this
Over the years, Buffett has made it clear he loves name-brand companies, simple-to-understand businesses, and clear visibility into the future of the businesses he buys. But there's one thing that he appreciates more than all of those, and that's high returns on invested capital.
Also referred to as ROIC, return on invested capital rolls off the tongue less casually, but it's not rocket science to understand. Basically, a business is only prosperous over the long haul if it can reinvest money (earnings) at a rate of return that exceeds the cost of raising that money.
In other words, businesses don't grow and compound on their success by reinvesting earnings in low-return projects: Those are essentially destroying value. Businesses grow their value -- what Buffett will call "compound" or "snowball" their value -- by reinvesting earnings in high-return projects.

The greater the returns on invested capital, the better. The lower the cost of capital, the better. And here's the breakdown of how to calculate ROIC:
ROIC = Operating Income (1-Tax Rate)/Invested Capital
The equation might be simple, but the task of finding high ROIC projects is not for many companies. So when Buffett identifies those companies that consistently generate returns in excess of their cost of capital, he springs into action. This, in large part, explains his interest in Unilever last year. Sure, he may appreciate its brands -- from Dove to Seventh Generation -- but it's the company's historical track record of generating juicy returns on invested capital that really got him salivating. Let's take a closer look.
