Discontinued Operations
Sale of Nextel Peru. In August 2013, we, together with our wholly-owned subsidiaries NII Mercosur Telecom, S.L. and NII Mercosur Moviles, S.L., completed the sale of all of the outstanding equity interests of our wholly-owned subsidiary, Nextel del Peru, S.A., or Nextel Peru, to Empresa Nacional de Telecomunicaciones S.A. and one of its subsidiaries, Entel Inversiones, S.A., which we refer to collectively as Entel, for $405.5 million in cash, which includes $50.0 million that was deposited in escrow on our behalf to satisfy potential indemnification claims. In 2013, we recognized a $2.8 million loss on the disposal of Nextel Peru in connection with this sale. In April 2014, we released $7.5 million of the amounts held in escrow to Entel as a result of the settlement of certain indemnification claims, and in February 2015, we released an additional $2.0 million as a result of the settlement of certain tax indemnification claims. The remaining funds held in escrow continue to be available to satisfy potential future indemnification claims.

In connection with the sale of Nextel Chile and Nextel Peru, we have reported the results of these operating companies as discontinued operations in our consolidated financial statements. Accordingly, we reclassified Nextel Chile's and Nextel Peru's results of operations for all periods presented to reflect Nextel Chile and Nextel Peru as discontinued operations. Unless otherwise noted, amounts included in these notes to our consolidated financial statements exclude amounts attributable to discontinued operations.
