(1) | Includes future minimum rental commitments related to leases executed for two office buildings in Cambridge, Massachusetts, which completed construction in July and November 2013. The leases both have 15 year terms and we have options to extend the term of each lease for two additional five-year terms. Future minimum rental commitments under these leases will total approximately $340.0 million over the initial 15 year lease terms.
As a result of our decision to relocate our corporate headquarters to Cambridge, Massachusetts, we vacated part of our Weston, Massachusetts facility in the fourth quarter of 2013. We incurred a charge of $27.2 million in connection with this move. This charge represents our remaining lease obligation for the vacated portion of our Weston facility, net of sublease income expected to be received. The term of our sublease to the vacated portion of our Weston facility started in January 2014 and will continue through the remaining term of our lease agreement. For additional information related to these transactions, please read Note 11, Property, Plant and Equipment to these consolidated financial statements.
