Amendment Description The Company is restating its interim unaudited consolidated financial statements for the quarter ended March 31, 2015. See the Company's Current Report on Form 8-K filed with the SEC on October 19, 2016 for additional details. When the Company disposes of real estate assets, if the real estate assets constitute a business, a portion of the Company’s goodwill should be allocated to the carrying value of the business disposed of to determine the gain/loss on disposal. Further, when the Company classifies real estate assets that constitute a business as held for sale, the carrying amount used to determine an impairment loss, if any, should include an allocation of goodwill, in accordance with ASC 350 “Intangibles - Goodwill and Other." Historically, the Company did not allocate goodwill resulting from the Cole II Merger to real estate assets disposed of or consider the amount of goodwill attributable to real estate assets held for sale in assessing impairment in the Company’s consolidated financial statements as of and for the three months ended March 31, 2015. As explained in Note 2 to the consolidated financial statements included within this Form 10-Q/A (as defined below), the restatement is a correction of an error in the application of the accounting treatment under ASC 350. For each real estate asset that constitutes a business that was disposed of or classified as held for sale, the restatement reflects an allocation of goodwill that has been derived based upon the proportionate fair value of the real estate asset to the fair value of the Company’s reporting unit (i.e. the Company's equity). This Amendment No. 1 on Form 10-Q/A (“Form 10-Q/A”) to our Quarterly Report on Form 10-Q for the quarter ended March 31, 2015, initially filed with the Securities and Exchange Commission (the “SEC”) on May 8, 2015 (the “Original Filing”), is being filed to reflect the restatement of (i) the Company’s consolidated balance sheet at March 31, 2015 and (ii) the Company’s consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for the three months ended March 31, 2015, and the notes related thereto. Additionally, although the effects were determined to be immaterial, the Company’s consolidated balance sheet as of December 31, 2014 and the Company’s consolidated statements of operations, comprehensive income and cash flows for the three months ended March 31, 2014 included in this Form 10-Q/A are being restated to reflect the correction of these errors. For the convenience of the reader, this Form 10-Q/A sets forth the Original Filing in its entirety and only amends and restates Items 1, 2, and 4 of Part I of the Original Filing to reflect the adjustments described above. No other information in the Original Filing is amended. For a more detailed description of these matters, see Note 2 to the accompanying consolidated financial statements in this Form 10-Q/A. Additionally, the Company remains in compliance with all of its debt agreements and financial covenants. Pursuant to the rules of the SEC, Item 6 of Part II of the Original Filing has been amended to contain the currently-dated certifications from our Chief Executive Officer and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002. The certifications of our Chief Executive Officer and Chief Financial Officer are attached to this Form 10-Q/A as Exhibits 31.1, 31.2 and 32.1, respectively.
