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, 2012 (“2012 Form 10-K”) and should be read in conjunction with such consolidated financial statements and related notes. The 2012 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2012 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, 2012 audited consolidated financial statements included in our 2012 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 June 30, 2013 and December 31, 2012, and the reported amounts of revenues and expenses for the three and six months ended June 30, 2013 and 2012. 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 June 30, 2013 and December 31, 2012, and the results of our operations and comprehensive income for each of the three and six months ended June 30, 2013 and 2012, and our cash flows for each of the six months ended June 30, 2013 and 2012, and all adjustments are of a normal recurring nature. Reclassifications Certain reclassifications have been made to the 2012 financial statements to conform to the 2013 presentation. Additionally, the results of operations for the six months ended June 30, 2013 include an adjustment of $1,561 to decrease depreciation and amortization expense which should have been recorded during previous periods. Management evaluated the impact of the adjustment and does not believe it is material to the results of the anticipated full year, current period or any previous period. IRS Tax Refund On August 24, 2009, we received a private letter ruling from the IRS granting favorable loss treatment under Sections 331 and 336 of the Code on the tax liquidation of one of our former taxable REIT subsidiaries. On November 6, 2009, legislation was signed that allowed businesses with net operating losses for 2008 or 2009 to carry back those losses for up to five years. As a result, we received a refund from the IRS of $40,418 in the fourth quarter of 2009 (the “Refund”) in connection with this tax liquidation. The IRS examination team, which is required by statute to review all refund claims in excess of $2,000 on behalf of the Joint Committee on Taxation, indicated to us that it disagreed with certain of the property valuations we obtained from an independent valuation expert in support of our fair value of the liquidated taxable REIT subsidiary and our claim for the Refund. During the year ended December 31, 2012, we reached an agreement with the regional office of the IRS on a proposed adjustment to the Refund. The total agreed-upon adjustment to taxable income was $13,700, which equates to $4,806 of taxes owed. We were also required to pay accrued interest of $490. During the year ended December 31, 2012, the Operating Partnership recorded the charge for the agreed-upon adjustment and the related estimated accrued interest which was reflected as a component of income tax expense. During 2013, the settlement amount was approved by the Joint Committee on Taxation. As a result of the Joint Committee on Taxation's approval, during 2013, we entered into closing agreements with the IRS that determined the timing of the settlement on the tax characterization of the limited partners of the Operating Partnership and the stockholders of the Company. Pursuant to these closing agreements, $8,238 of the preferred stock distributions for the year ended December 31, 2012 are taxable as capital gain. During the three months ended June 30, 2013, we paid the agreed upon taxes and related accrued interest. Recent Accounting Pronouncements In February 2013, the FASB issued Accounting Standards Update No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). ASU 2013-02 requires that public companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. ASU 2013-02 is effective for annual periods beginning after December 15, 2012, and is to be applied prospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.
