(Telecompaper) AT&T has closed its acquisition of NII Holdings' Nextel Mexico business for USD 1.875 million after the deal was approved by Mexico's telecom regulator IFT and the US Bankruptcy Court for the Southern District of New York, which is overseeing the restructuring of NII Holdings. The acquisition excludes around USD 427 million of net debt and other adjustments. The deal marks AT&T's second purchase of a Mexican mobile operator this year following its January acquisition of Iusacell for USD 2.5 billion. AT&T acquired all the companies operating under the name Nextel, including spectrum licenses, network assets, retail stores and subscribers, and the company said it will now integrate Iusacell and Nextel into a single operator.
