Earlier this week Answers.com (ANSW) announced the acquisition of Lexico for $100 million in cash. At the time of the announcement this acquisition price was slightly greater than Answers.com's market cap.
Lexico operates websites at dictionary.com, thesaurus.com, and reference.com. Because Lexico generates minimal revenues, many are basically calling this an asset acquisition.
