Yahoo, which is in the process of auctioning off its search and advertising business, said on Monday its board had made "great progress on strategic alternatives" but did not comment further on the auction process. The company is expected to choose a winner this week.

The company also reported quarterly earnings that fell short of Wall Street expectations in what may be its last financial report before it sells its core business.

Yahoo declined to comment on the article.
