Impairment and Restructuring Charges

Asset Impairments.
In accordance with the FASB's authoritative guidance on the impairment and disposal of long-lived assets, we review our long-lived assets for impairment whenever events and circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. The recoverability of an asset or asset group held and used is measured by a comparison of the carrying amount of the asset or asset group to the estimated and undiscounted future cash flows expected to be generated by the asset or asset group.
Although we plan to continue to support our operations in Argentina, we are also exploring various strategic options for this market, such as partnerships, service arrangements and asset sales, to maximize the value of Nextel Argentina and generate additional liquidity. As a result of the review of our long-lived assets and our exploration of strategic options for Nextel Argentina in 2014, we determined that the carrying value of Nextel Argentina's asset group, which includes all of the operating assets and liabilities held by our Argentine segment, was not recoverable. Accordingly, we recorded a non-cash asset impairment charge of $84.7 million to reduce the carrying amount of the asset group to its estimated fair value. We estimated the fair value of Nextel Argentina's asset group using assumed proceeds from a potential disposition, which is a Level 3 input within the fair value hierarchy under the FASB's authoritative guidance on fair value measurements. During 2014, we also tested the long-lived assets in our Nextel Brazil and Nextel Mexico segments for recoverability and, based on our estimates of undiscounted cash flows, determined the carrying values to be recoverable. Our estimates of undiscounted cash flows for each asset group exceeded the carrying value of the respective asset groups.
In 2014, we evaluated strategic options for the next generation of our push-to-talk services and determined that, for one of these options, further development was no longer probable. As a result, we recognized a $47.9 million asset impairment charge, $5.1 million of which was recognized by Nextel Mexico and the remainder of which was recognized at the corporate level.
We recognized a $6.4 million asset impairment charge at the corporate level related to the sale of our corporate aircraft in 2014.
During 2014, we also recognized $25.5 million in asset impairment charges, the majority of which related to the shutdown or abandonment of approximately 300 transmitter and receiver sites in Brazil and Mexico and about 50 retail store closures in Brazil related to the realignment of our distribution channels.
In 2013, we discontinued the use of software previously developed to support our customer relationship management systems. As a result of this evaluation, in the first quarter of 2013, we recognized an asset impairment charge of $85.3 million related to the discontinuation of this software, of which $76.3 million was recognized at the corporate level and $9.0 million was recognized by Nextel Mexico.

We recognized a $5.9 million asset impairment at the corporate level in 2013 related to the discontinuation of the development of certain network features.

During 2012, we recognized $22.8 million in asset impairment charges, the majority of which related to the write-off of certain information technology projects at the corporate level.

Restructuring Charges.

During 2014, we recognized $48.4 million in severance and related costs as a result of the termination of employees at the corporate level and in our markets. These actions included the separation of:
approximately 85 employees at the corporate level, all of whom were severed in the second quarter of 2014;
approximately 800 employees in Brazil, all of whom were severed in the third quarter of 2014;
approximately 1,170 employees in Mexico, 800 of whom were severed in the second quarter of 2014 and the remainder of whom were severed in the third quarter of 2014; and
about 20 employees in Argentina, all of whom were severed in the second half of 2014.
We terminated these employees in an effort to streamline our organizational structure and reduce general and administrative expenses.
In 2009, we outsourced our network operations to a third party. During 2013, we restructured and amended this agreement, reduced the scope of the services provided, added terms to facilitate the transition of those services to us and established the terms on which further transitions of services and the termination of the arrangements could be implemented in each of our markets. Under the outsourcing agreements in effect prior to this restructuring, we classified a portion of the base contractual fees as a prepayment and were recognizing this prepayment over the life of the previous agreement. As a result of this restructuring, we recognized a non-cash charge of $38.2 million relating to the write-off of the remainder of the prepayment during 2013. In 2014, we settled certain refund claims related to this outsourcing agreement, which resulted in a restructuring benefit of $3.2 million.
During 2014, we recognized a $4.5 million charge related to the cessation of our utilization of certain network services in Brazil.
In 2013, we recognized $30.1 million in restructuring charges, the majority of which was related to the separation of approximately 800 employees at the corporate level and in Mexico, in connection with an organizational realignment plan that we designed to simplify the roles and responsibilities of both our headquarters and market organizations and to reduce general and administrative expenses.

During 2013, we recognized $6.8 million in contract termination costs incurred in connection with the sublease of certain excess space located in one of our corporate office buildings.

During 2012, we recognized $7.6 million in restructuring charges at the corporate level, primarily related to the separation of approximately 50 employees in conjunction with certain actions taken to realign resources and roles between our corporate headquarters and operating segments.
