Organization and Basis of Presentations	Organization and Basis of Presentations Organization Ramco-Gershenson Properties Trust, together with its subsidiaries (the “Company” or "RPT"), is a real estate investment trust (“REIT”) engaged in the business of owning, developing, redeveloping, acquiring, managing and leasing community shopping centers in strategic metropolitan markets throughout the Eastern, Midwestern and Central United States. As of March 31, 2014, our property portfolio consists of 66 wholly owned shopping centers and one office building comprising approximately 13.2 million square feet. In addition, we are co-investor in and manager of two institutional joint ventures that own portfolios of shopping centers. We own 20% of Ramco 450 Venture LLC, an entity that owns eight shopping centers comprising approximately 1.6 million square feet. We own 30% of Ramco/Lion Venture L.P., an entity that owns three shopping centers comprising approximately 0.8 million square feet. We also have ownership interests in two smaller joint ventures that each own a shopping center. In addition, we own interests in three parcels of land held for development or available for sale and five parcels of land adjacent to certain of our existing developed properties located in Florida, Georgia, Michigan, Tennessee, and Virginia. Most of our properties are anchored by supermarkets and/or national chain stores. The Company’s credit risk, therefore, is concentrated in the retail industry. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Company and our majority owned subsidiary, the Operating Partnership, Ramco-Gershenson Properties, L.P. (96.8% owned by the Company at March 31, 2014 and December 31, 2013), and all wholly-owned subsidiaries, including entities in which we have a controlling financial interest. We have elected to be a REIT for federal income tax purposes. All intercompany balances and transactions have been eliminated in consolidation. The information furnished is unaudited and reflects all adjustments which are, in the opinion of management, necessary to reflect a fair statement of the results for the interim periods presented, and all such adjustments are of a normal recurring nature. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2013. The preparation of our unaudited financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts that are not readily apparent from other sources. Actual results could differ from those estimates. Reclassifications Certain reclassifications of prior period amounts, primarily related to discontinued operations, have been made in the condensed consolidated financial statements in order to conform to the current presentation. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-08 "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" which amends the requirements for reporting discontinued operations. Under ASU 2014-08, a disposal of a component of an entity or a group of components of an entity is required 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. For public entities, ASU 2014-08 is effective prospectively for fiscal years beginning after December 15, 2014; however, early adoption is permitted, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We adopted the provisions of ASU 2014-08 beginning with the period ended March 31, 2014, and have applied the provisions prospectively. Prior to the adoption of ASU 2014-08, the results of operations for operating properties sold or held for sale during the reported periods were shown under Discontinued Operations on the Consolidated Statements of Operations. Beginning with the period ended March 31, 2014, activity related to individual sales of properties wholly-owned or co-owned with joint ventures will no longer be classified as Discontinued Operations. In July 2013, the FASB updated ASC 740 "Income Taxes" with ASU 2013-11 "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carry forward, a Similar Tax Loss, or a Tax Credit Carry forward Exists." The objective of this update is to reduce the diversity in practice related to the presentation of certain unrecognized tax benefits. The amendments in this update require an entity to present an unrecognized tax benefit in the financial statements as a reduction to a deferred tax asset for those instances described above, except in certain situations described in the update. For public entities, ASU 2013-11 is effective for fiscal years beginning after December 15, 2013 and interim periods within those years. The guidance should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Early adoption and retrospective application are permitted. The adoption of this guidance did not have an impact on our consolidated financial statements. In July 2013, the FASB updated ASC 815 "Derivatives and Hedging" with ASU 2013-10 "Inclusion of the Fed Funds Effective Swap Rate (of Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes." ASU 2013-10 permits the Overnight Index Swap ("OIS") Rate, also referred to as the Fed Funds effective Swap Rate, to be used as a U.S. benchmark for hedge accounting purposes, in addition to London Interbank Offered Rate ("LIBOR") and the interest rate on direct U.S. Treasury obligations. The guidance also removes the restriction on using different benchmarks for similar hedges. ASU 2013-10 is effective prospectively for qualifying new or re-designated hedges entered into on or after July 17, 2013. The adoption of this guidance did not have an impact on our consolidated financial statements.
