Yahoo's Q1 does not change value for Microsoft -sources

SAN FRANCISCO, April 22 (Reuters) - Yahoo Inc's (YHOO.O) first-quarter results have not changed Microsoft Corp's (MSFT.O) view of the Internet company's value, people familiar with Microsoft's thinking said on Tuesday.

Microsoft sees Yahoo's decision not to raise its full-year revenue forecast as a reflection that the company's value has not changed since January, when it provided the same 2008 revenue estimates, pushing its shares down to a four-year low, these people said.

That point of view reiterates Microsoft Chief Executive Steve Ballmer's comments from Morocco earlier on Tuesday.

"I wish Yahoo all the success with its results, but it doesn't affect the value of Yahoo to Microsoft," Ballmer said. (Reporting by Anupreeta Das and Daisuke Wakabayashi)
