In the opinion of management, the statements for the interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for such periods. Results for these interim periods are not necessarily indicative of full year results.

All intercompany balances and transactions have been eliminated in consolidation. Certain prior year balances have been reclassified in the condensed consolidated unaudited statements of operations to combine acquisition related expenses with general and administrative expenses and to separately present merger related expenses from general and administrative expenses. </font></div><div style="line-height:120%;padding-top:12px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company evaluates its relationships and investments to determine if it has variable interests. A variable interest is an investment or other interest that will absorb portions of an entity’s expected losses or receive portions of the entity’s expected residual returns. If the Company determines that it has a variable interest in an entity, it evaluates whether such interest is in a variable interest entity (“VIE”). A VIE is broadly defined as an entity where either (1) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company consolidates any VIEs when it is determined to be the primary beneficiary of the VIE’s operations.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors include, but are not limited to, the Company’s ability to direct the activities that most significantly impact the entity’s economic performance, its form of ownership interest, its representation on the entity’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and to replace the manager of and/or liquidate the entity.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company continually evaluates the need to consolidate joint ventures, if any, based on standards set forth in GAAP. In determining whether the Company has a controlling interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, power to make decisions and contractual and substantive participating rights of the partners/members as well as whether the entity is a VIE for which the Company is the primary beneficiary. The Company has no relationship, investment or other interests in entities that are or were required to be consolidated because the Company has no variable interests in an entity that qualifies as a VIE.</font></div></div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.Reference 1: http://www.xbrl.org/2003/role/presentationRef

When indicators of potential impairment are present, the Company assesses the recoverability of the assets by determining whether the carrying amount of the assets will be recovered through the undiscounted future cash flows expected from the use of the assets and their eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying amount, the Company will adjust the real estate and related assets to their respective fair values and recognize an impairment loss. Generally, fair value is determined using a discounted cash flow analysis and recent comparable sales transactions.</font></div><div style="line-height:120%;padding-top:12px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company continually monitors certain properties for which it has identified impairment indicators.

Should the conditions related to any of these, or any of the Company’s other properties change, the underlying assumptions used to determine the expected undiscounted future cash flows may change and adversely affect the recoverability of the respective real estate and related assets’ carrying amounts. </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">No</font><font style="font-family:inherit;font-size:10pt;"> impairment losses were recorded related to the </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">Identified Properties</font><font style="font-family:inherit;font-size:10pt;"> during the </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">three and six</font><font style="font-family:inherit;font-size:10pt;"> months ended </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June 30, 2013</font><font style="font-family:inherit;font-size:10pt;">.

As a result, the Company reduced the carrying amount of the real estate and related assets to their estimated fair value by recognizing an impairment loss of </font><font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;">$2.0 million</font><font style="font-family:inherit;font-size:10pt;"> during the </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">three and six</font><font style="font-family:inherit;font-size:10pt;"> months ended </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June 30, 2012</font><font style="font-family:inherit;font-size:10pt;">. </font></div><div style="line-height:120%;padding-top:12px;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When developing estimates of expected future cash flows, the Company makes certain assumptions regarding future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, terminal capitalization and discount rates, the expected number of months it takes to re-lease the property, required tenant improvements and the number of years the property will be held for investment. The use of alternative assumptions in estimating expected future cash flows could result in a different determination of the property’s expected future cash flows and a different conclusion regarding the existence of an impairment, the extent of such loss, if any, as well as the fair value of the real estate and related assets.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When a real estate asset is identified by the Company as held for sale, the Company ceases depreciation and amortization of the assets related to the property and estimates the fair value, net of selling costs.
