Mark Bertolini spoke out for the first time about the reason he's decided to move Aetna's headquarters out of Hartford, Connecticut, where the company was founded more than 160 years ago.

"We haven't told anybody where yet, but it will be sort of an investment in attracting different kinds of people into our organization," said Bertolini on CNBC Europe's "Street Signs," adding "as we have to move away from being just an insurance company to actually impacting the underlying health of the population, that requires younger people, technologists, innovation."
