Problem with this letter is now the Yahoo board is responsible for bringing close to that value or more to shareholders or they'll be sued and lose.

Dear Marissa,

Starboard Value LP, together with its affiliates ("Starboard"), is currently a significant shareholder of Yahoo! Inc. ("Yahoo" or the "Company").

By way of background, Starboard Value LP is an investment management firm that seeks to invest in undervalued and underperforming public companies. Our approach to such investments is to actively engage and work closely with management teams and boards of directors in a constructive manner to identify and execute on opportunities to unlock value for the benefit of all shareholders. Our principals and investment team have extensive experience and a successful track record of enhancing value at portfolio companies through a combination of strategic refocusing, improved operational execution, and more efficient capital allocation.

The purpose of this letter is to highlight several opportunities to unlock tremendous value for the benefit of all Yahoo shareholders. These opportunities include:

Unlocking the substantial value from Yahoo's non-core minority equity stakes in Alibaba Group Holding Limited ("Alibaba") and Yahoo Japan in a structure that delivers value directly to Yahoo shareholders in a tax-efficient manner;
Realizing substantial cost efficiencies by reducing expenses throughout the Company, specifically with a goal of reducing losses in the Display business by between $250 and $500 million;
Halting Yahoo's aggressive acquisition strategy which has resulted in $1.3 billion of capital spent since Q2 2012 while consolidated revenues have remained stagnant and EBITDA has materially decreased; and
Exploring a strategic combination with AOL, Inc. – a company we know well – which could improve Yahoo's competitive position, deliver cost synergies of up to $1 billion, and potentially facilitate the realization of value from Yahoo's non-core equity stakes with minimal tax leakage.

We believe that the execution of these initiatives would produce tremendous value for shareholders, and are squarely within the control of the Company's management and board of directors (the "Board"). We look forward to engaging directly with you to discuss the details of how these actions can be implemented in a timely manner.... http://finance.yahoo.com/news/starboard-delivers-letter-ceo-board-160700399.html
