Yahoo CEO Carol Bartz assured stock market analysts that the Internet company is trying to repair the damage caused by a recent change in a key investment in China, according to AP. Bartz made her remarks Wednesday at the start of a six-hour meeting scheduled to update Wall Street on Yahoo's turnaround strategy. But investors have been focused on a surprising May 10 disclosure that threatens to diminish the value of Yahoo's 43 percent stake in Chinese Internet company Alibaba Group. Yahoo's market value has dropped by 12 percent, or nearly $3 billion, since the company revealed Alibaba had spun off its online payment service Alipay into another company. Although she didn't offer a timetable for reaching an agreement, Bartz said is confident Yahoo will be «appropriately compensated» for the Alipay spinoff.
