1. Organization and Summary of Significant Accounting Policies

Organization

Apple Hospitality REIT, Inc., together with its wholly-owned subsidiaries (the “Company”), is a Virginia corporation that has elected to be treated as a real estate investment trust (“REIT”) for federal income tax purposes. The Company is a self-advised REIT that invests in income-producing real estate, primarily in the lodging sector, in the United States. The Company’s fiscal year end is December 31. The Company has no foreign operations or assets and its operating structure includes only one reportable segment. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated. Although the Company has interests in potential variable interest entities through its purchase commitments, it is not the primary beneficiary as the Company does not have any elements of power in the decision making process of these entities, and therefore does not consolidate the entities. As of March 31, 2017, the Company owned 236 hotels with an aggregate of 30,203 rooms located in 33 states, including one hotel with 224 rooms classified as held for sale, which was sold to a third party in April 2017. The Company’s common shares are listed on the New York Stock Exchange under the ticker symbol “APLE.”

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include all of the information required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These unaudited financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in its 2016 Annual Report on Form 10-K. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the twelve month period ending December 31, 2017.

Use of Estimates

The preparation of the financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Net Income Per Common Share

Basic net income per common share is computed based upon the weighted average number of shares outstanding during the period. Diluted net income per common share is calculated after giving effect to all potential common shares that were dilutive and outstanding for the period. Basic and diluted net income per common share were the same for each of the periods presented.

Accounting Standards Recently Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which is intended to add guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for annual and interim periods beginning after December 15, 2017 with early adoption permitted. The Company adopted this standard effective January 1, 2017 on a prospective basis. Prior to the adoption of this standard, the Company’s acquisitions of hotel properties were accounted for as existing businesses, and therefore all transaction costs associated with the acquisitions, including title, legal, accounting, brokerage commissions and other related costs were expensed as incurred. Under the new standard, effective January 1, 2017, acquisitions of hotel properties (including the acquisition of one hotel during the first quarter of 2017, as discussed in Note 3) will generally be accounted for as acquisitions of a group of assets, with costs incurred to effect an acquisition being capitalized as part of the cost of the assets acquired, instead of accounted for separately as expenses in the period that they are incurred. Asset acquisitions now require the Company to complete its allocation of the purchase price at the time of the acquisition as the measurement period applicable to business combinations does not apply to asset acquisitions.

Accounting Standards Recently Issued

In February 2017, the FASB issued ASU No. 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20), Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which clarifies the scope of Accounting Standards Codification (“ASC”) Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets. The standard is effective for annual and interim periods beginning after December 15, 2017 with early adoption permitted. The standard requires a retrospective or modified retrospective transition approach. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
