Yahoo says Microsoft search providing 31 percent of revenues

Bloomberg is reporting that a U.S. Securities and Exchange Commission (SEC) request has resulted in Yahoo disclosing on December 9 that 31 percent of its latest quarterly revenues are attributable to the search deal it forged with Microsoft.

As the December 10 Bloomberg report noted, that's substantially more than the 10 percent of sales Yahoo had publicly claimed that it was earning from the Microsoft pact.

A quick refresher: In July 2009, Microsoft and Yahoo signed a 10-year deal following Microsoft's decision against buying Yahoo for $45 billion, as it had hoped back in 2008. The 2009 deal specified that Microsoft would power Yahoo search, and Yahoo become the ad sales force for Microsoft's premium properties.
