Summary Box: Yahoo encounters more turbulence

NEW CHALLENGES: Yahoo’s negotiations to sell most of its Asian holdings fell apart Tuesday and a major shareholder outlined plans to win four seats on the company’s board.

ASIA DISCORD: The talks to sell Yahoo Inc.’s stakes in China’s Alibaba Group and Yahoo Japan ended in a disagreement over the sales price, according to a person familiar with the matter. Another knowledgeable person said Yahoo had second thoughts after agreeing to terms in late December.

SHAREHOLDER UNREST: New York hedge fund manager Daniel Loeb says he doesn’t trust Yahoo’s current board to make smart decisions.
