Time Warner Inc. will be soon be completely separated from its Time magazine unit, which will become an independent, publicly traded company.

Time Warner aims to complete the proposed transaction by the end of the calendar year.

Time Warner Chairman and Chief Executive Officer Jeff Bewkes said: "After a thorough review of options, we believe that a separation will better position both Time Warner and Time Inc. A complete spin-off of Time Inc. provides strategic clarity for Time Warner Inc., enabling us to focus entirely on our television networks and film and TV production businesses, and improves our growth profile. Time Inc. will also benefit from the flexibility and focus of being a stand-alone public company and will now be able to attract a more natural stockholder base. As we saw with the prior spin-offs of Time Warner Cable and AOL, we expect the separation will create additional value for our stockholders."

Time Inc. is a multi-platform publishing and branded content company, reaching nearly half of U.S. adults each month and millions of consumers around the world.

The proposed transaction will be structured as tax-free to Time Warner stockholders. The transaction is contingent on the satisfaction of a number of conditions, including completion of the review process by the Securities and Exchange Commission of required filings under applicable securities regulations and the final approval of transaction terms by Time Warner's Board of Directors.

Magazines are challenged as people turn to smart phones and tablets to read and advertisers have been spending money on electronic media.
