Court filings indicate Yahoo (YHOO -0.6%) didn't want to use the Yahoo Bing Network as its search ad platform in Taiwan and Hong Kong, in spite of Yahoo and Microsoft's (MSFT -0.6%) search partnership. A U.S. judge has ruled Yahoo can't back out.
Marissa Mayer has expressed "disappointment" over the performance of Yahoo's search partnership with Microsoft, which includes revenue-payment guarantees from Microsoft that were extended by a year this spring.
Yahoo's search paid click volume rose 21% Y/Y in Q3, but its price-per-click (exc. Microsoft payments) fell 4%.
Though Yahoo as reportedly considered abandoning the Microsoft partnership for one with Google in the past, the Microsoft deal isn't set to expire until 2020, and antitrust regulator will likely be unhappy if Google search began powering Yahoo's results instead of Bing.
