(“ACS”), GCI, ACS Wireless, Inc., a wholly owned subsidiary of ACS (“ACS Member”), GCI Wireless Holdings, LLC, a wholly owned subsidiary of GCI, and The Alaska Wireless Network, LLC (“AWN”), pursuant to which the parties agreed to contribute the respective wireless network assets of GCI, ACS and their affiliates to AWN.  This transaction provides a robust, statewide network with the spectrum mix, scale, advanced technology and cost structure necessary to compete with Verizon Wireless and AT&T Mobility, LLC in Alaska.   AWN will provide wholesale services to GCI and ACS.  GCI and ACS will use the AWN network in order to continue to sell services to their respective retail customers.  GCI and ACS will continue to compete against each other and other wireless providers in the retail market. Under the terms of the Wireless Agreement, we purchased certain wireless network assets from ACS and its affiliates for $100.0 million and we contributed the purchased assets, our wireless network assets and certain rights to use capacity to AWN.  ACS contributed its remaining wireless network assets and certain rights to use capacity to AWN.  Upon the contribution of assets to AWN, the ACS Member owns one-third of AWN and we own two-thirds of AWN.  The ACS Member will be entitled to receive preferential cash distributions totaling $190.0 million over the first four years of AWN's operations and we will be entitled to all remaining cash distributions during that period.  Following the initial four year period, we and the ACS Member will receive distributions proportional to our ownership interests.  We are evaluating the accounting treatment for this transaction. Upon closing the AWN transaction our wireless network assets contributed to AWN were released from the lien under our Amended Senior Credit Facility. We funded the purchase of wireless network assets from ACS and its affiliates by borrowing $100.0 million on our Amended Senior Credit Facility delayed draw term loan on July 17, 2013.falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued.
