Berkshire Hathaway Inc. CEO Warren Buffett told the company's shareholders in a letter on Saturday that they can rest assured that a substantial majority of their money will "forever [be] deployed" in equities. He stressed that Berkshire will "never" prefer to own cash-equivalent assets over "good businesses."

"Paper money can see its value evaporate if fiscal folly prevails. In some countries, this reckless practice has become habitual, and, in our country’s short history, the US has come close to the edge. Fixed-coupon bonds provide no protection against runaway currency," Buffett explained.
