There has been a company restructuring recipe that has worked for decades. Buy a company, trim the fat, then reinvest to facilitate growth, and make lots of money. But sometimes this recipe doesn’t work — and the story of Kraft Heinz is a prime example. Earlier this year, the company suffered a massive loss in less than 24 hours — $4.3 billion, to be precise. And over a two-year period, the fiasco cost Berkshire Hathaway $20 billion, possibly its worst loss ever.
