Warren Buffett on Kraft Heinz: 'We paid too much'
Kraft Heinz has been a thorn for Berkshire, which in February took a $3 billion writedown on its 26.7 percent stake.
While Buffet said its current problems can't be blamed on a lack of investment,
he also said Berkshire Hathaway had paid too much for Kraft.
You can turn any investment into a bad deal by paying too much.
