Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the accounting policies described in the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2014 ("2014 Form 10-K") and should be read in conjunction with such consolidated financial statements and related notes. The 2014 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2014 Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The following notes to these interim consolidated financial statements highlight significant changes to the notes included in the December 31, 2014 audited consolidated financial statements included in our 2014 Form 10-K and present interim disclosures as required by the Securities and Exchange Commission. In order to conform with GAAP, in preparation of our consolidated financial statements we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of March 31, 2015 and December 31, 2014, and the reported amounts of revenues and expenses for the three months ended March 31, 2015 and 2014. Actual results could differ from those estimates. In our opinion, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of our financial position as of March 31, 2015 and December 31, 2014, the results of our operations and comprehensive income for each of the three months ended March 31, 2015 and 2014, and our cash flows for each of the three months ended March 31, 2015 and 2014; all adjustments are of a normal recurring nature. Reclassifications Certain reclassifications have been made to the 2014 financial statements to conform to the 2015 presentation. Discontinued Operations Effective January 1, 2015, we adopted Accounting Standards Update ("ASU") No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08") for all properties not previously sold. ASU 2014-08 revised the reporting requirements to only allow a component of an entity, or group of components of an entity, to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Going forward, we expect the majority of our property dispositions will not qualify as discontinued operations and the results of the dispositions, including gain on sale of real estate, will be presented in Income from Continuing Operations. Recent Accounting Pronouncements In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis" (“ASU 2015-02”). ASU 2015-02 updates consolidation guidance for legal entities such as limited partnerships, limited liability companies and securitization structures in an attempt to simplify consolidation accounting. ASU 2015-02 eliminates the presumption that a general partner should consolidate a limited partnership, modifies the evaluation of whether limited partnerships are variable interest entities or voting interest entities and adds requirements that limited partnerships must meet to qualify as voting interest entities. ASU 2015-02 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted. The adoption of ASU 2015-02 is not expected to have an impact on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"), which amends the current presentation of debt issuance costs in the financial statements. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, instead of as an asset. The amendments are to be applied retrospectively and are effective for interim and annual periods beginning after December 15, 2015. The adoption of the new guidance is not expected to have a material impact on our consolidated financial statements.
