I wonder why they're deciding to offer an All-Cash offer rather than some part of the offer being in Stock. Yahoo's stock has done well lately and should be fairly attractive to Tumblr investors and management. Given the size of the potential acquisition, there aren't that many alternative suitors, so Yahoo should have pretty good leverage here, especially since Tumblr has gotten heat over the last few years regarding their lack of a business model. Maybe Yahoo is afraid that offering say ~$400MM in stock would dilute the existing shares and irritate existing shareholders?
