The "investment group" is the private buyer? And the founder and company CEO Michael Dell is a member of the group?
Context:
Dell announced Tuesday it agreed to a $24.4 billion private buyout deal that would give control of the computer maker to an investment group that includes founder and company CEO Michael Dell and technology investment firm Silver Lake.
The deal is expected to be completed by the end of the second quarter, and Dell's stock will be delisted. Its stockholders will then receive $13.65 in cash for each share. It's a 25% increase over the closing share price on Jan. 11, the last trading day before rumors of a possible buyout deal were leaked.
