Third Point's letter, released in a regulatory filing Wednesday, comes a week after the hedge fund said it would launch a campaign to get its four nominees on the board if the Yahoo's management didn't accept them.
The proposed directors are Daniel Loeb, the hedge fund's manager; former NBC Universal CEO Jeff Zucker; former MTV Networks executive Michael Wolf and turnaround specialist Harry Wilson.
The company's board is in the midst of changes. Of the 11 directors, four, including Chairman Roy Bostock, have said they will step down at Yahoo's annual meeting, which is usually held in late June. The departures are part of an attempt to placate shareholders frustrated with a long-running financial funk that has depressed the company's stock price.
The company also appointed two new directors to its board last month. But Third Point's letter said that the appointed directors were not in the best interests of Yahoo, and the board still lacked expertise in the media and entertainmentindustries, as well as in corporate restructurings.
Yahoo shares were up in morning trading Wednesday. Shares have ranged from $11.09 to $18.84 in the past 12 months. (Click here for the latest Yahoo quote)
