The unaudited pro forma condensed statements of operations for the fiscal year ended December 31, 2012 and for the six months ended June 30, 2013 give effect to the Transactions as if they were consummated on January 1, 2012.  The unaudited pro forma condensed balance sheet as of June 30, 2013 gives effect to the Transactions as if they were consummated on June 30, 2013.  The unaudited pro forma consolidated information has been derived from (i) the audited consolidated financial statements of each of Security Networks and the Company for the year ended December 31, 2012 and (ii) the unaudited consolidated financial statements of each of Security Networks and the Company as of and for the three and six months ended June 30, 2013 incorporated by reference herein.

The unaudited pro forma consolidated financial information has been presented for informational purposes only and does not purport to represent, and is not necessarily indicative of, what our financial position or results of operations would have been had the Transactions been completed as of January 1, 2012 and June 30, 2013, as applicable, and should not be taken as representative of our future consolidated financial position or results of operations.  This information is only a summary and should be read in conjunction with the accompanying notes to the unaudited pro forma condensed consolidated financial statements and our historical consolidated financial statements and related notes thereto and Security Networks’ historical consolidated financial statements and related notes thereto incorporated by reference herein.

The Acquisition will be accounted for as a business combination utilizing the purchase accounting method in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations.  The pro forma information presented below, including the purchase price and allocation of purchase price, is based on estimates of the fair values of assets acquired and liabilities assumed, available information as of the date of this report and management assumptions, and may be revised as additional information becomes available.  The final purchase price and purchase price allocation is dependent upon, among other things, the finalization of the asset and liability valuations by our independent appraisal firm.  Any post-closing adjustments may change the purchase price or the allocation of the purchase price, which could affect the fair value assigned to the assets and liabilities and could result in a change to the unaudited pro forma condensed consolidated financial information, including a change to goodwill. The unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 2012 has been revised from the preliminary pro forma financial information included in previous filings due to changes in estimates associated with the allocation of purchase price.

The historical consolidated financial information has been adjusted to give effect to pro forma events that are (a) directly attributable to the Transactions, (b) factually supportable, and (c) with respect to the statements of income, expected to have a continuing impact on the combined results.
