When Michael Dell took over the reins of Dell and took the company private in 2013, one of the stated reasons was to gain new flexibility that wasn’t possible as a publicly traded company. Today, Dell announced it would purchase EMC in a deal worth $67 billion that’s already been hailed as the largest tech deal of all time. Michael Dell will become CEO of the new company, but it’s not clear what role Joe Tucci, the CEO of EMC and chairman of the company, will play going forward.

Buying EMC gives Dell access to a huge market for information storage and virtualization technology. EMC owns companies like VMWare and Mozy as well as RSA Security. Dell agreed to pay a significant premium for the company through issuing new common equity, tracking stock, debt financing, and cash on hand.
