In October 2013, Loeb issued a letter scrutinizing the governance of Sotheby's. It announced that Third Point had acquired "9.3% of the outstanding shares" and addressed Third Point's concerns regarding the governance of Sotheby's. These concerns are summarized as, "we are troubled by the Company's chronically weak operating margins and deteriorating competitive position relative to Christie's, as evidenced by each of the Contemporary and Modern art evening sales over the last several years." The letter expressed strong skepticism of Sotheby's international strategy—"Sotheby's is struggling internationally, lagging in newer markets like China and the Middle East"—and called for the removal of William Ruprecht from all his positions.
