Item 8.01 Other Events

As previously announced, on December 16, 2013, Frontier Communications Corporation (the “Company”) entered into an agreement (such agreement as amended, the “Stock Purchase Agreement”) to acquire the wireline properties of AT&T Inc. (“AT&T”) in Connecticut for a purchase price of $2.0 billion in cash. Pursuant to the Stock Purchase Agreement, the Company agreed to acquire all of the issued and outstanding capital stock of The Southern New England Telephone Company and SNET America, Inc. (the “Transferred Companies”) from AT&T. Prior to the closing of the AT&T Transaction (as defined below), (i) AT&T transferred to the Transferred Companies certain assets and caused the Transferred Companies to assume certain liabilities relating to the business to be acquired and (ii) the Transferred Companies transferred to AT&T certain assets, and AT&T assumed certain liabilities of the Transferred Companies, to be retained by AT&T following the closing (the Transferred Companies, after giving effect to such transactions, being referred to as the “Connecticut Operations”). References to the “AT&T Transaction” refer to our acquisition of the Connecticut Operations from AT&T on October 24, 2014 pursuant to the Stock Purchase Agreement.
