Berkshire Hathaway to buy back shares

(Reuters) - Warren Buffett's conglomerate Berkshire Hathaway <BRKa.N> said on Monday it will launch a share buyback program, an extremely rare move from Buffett that comes after months of investor complaints the stock was undervalued.

Berkshire said it would buy back Class A and Class B shares at a premium of no more than 10 percent to book value per share.
