Berkshire Hathaway did not change its holdings of GHC during the first quarter of 2014. On March 12, it announced plans to trade roughly 1.6 million Graham Holdings shares for a Miami television station, some Berkshire shares owned by Graham and some cash. Graham Holdings is what remained after The Washington Post Co. sold its namesake newspaper to Amazon chief Jeff Bezos for $250 million last August.
