It is unclear why Buffett appeared to have soured on Exxon, or whether Berkshire made money on the investment.

Exxon Mobil declined to comment.
Berkshire also reported a new stake of 4.7 million shares in Rupert Murdoch's media company Twenty-First Century Fox.
It further reported a new 8.4 million-share stake in Restaurant Brands International, the parent of the Burger King and Tim Hortons restaurant chains. Berkshire helped finance Burger King's purchase of Tim Hortons last year and got Restaurant Brands shares through the merger.
Berkshire also added to holdings in IBM, General Motors, Phillips 66, Suncor Energy and DirecTV, among others, and shed stakes in oil company ConocoPhillips and pharmacy benefits management company Express Scripts.
