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 (“U.S.”). 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 June 30, 2019, the Company owned 234 hotels with an aggregate of 30,046 rooms located in 34 states. The Company’s common shares are listed on the New York Stock Exchange (“NYSE”) 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 U.S. generally accepted accounting principles (“GAAP”) 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 Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”). Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the twelve month period ending December 31, 2019. Use of Estimates The preparation of the financial statements in conformity with GAAP 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which replaces Leases (Topic 840), and along with subsequent amendments, provides the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). Under the new standard, lessees are required to recognize most leases on their balance sheets as right-of-use assets and lease liabilities. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. Leases with a term of 12 months or less are accounted for similarly to the previous accounting guidance under Leases (Topic 840), for operating leases. Topic 842 requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which provides entities another optional transition method, which the Company elected, to apply the new standard using the modified retrospective approach at its effective date, versus restating the prior periods presented, and recognizing a cumulative-effect adjustment to the opening balance of retained earnings for the effect of initially applying Topic 842 in the period of adoption. Consequently, an entity’s reporting for periods presented prior to adoption of the new lease requirements in the consolidated financial statements would continue in accordance with Leases (Topic 840), including disclosures. The Company adopted Topic 842 effective January 1, 2019, electing to recognize and measure its leases prospectively at the beginning of the period of adoption through a cumulative-effect adjustment to shareholders’ equity, without restating the presentation of periods prior to the effective date, which continue to be reported in accordance with the Company’s historical accounting policy. At adoption, the Company recorded a cumulative-effect adjustment totaling approximately $5.2 million to distributions greater than net income, a component of shareholders’ equity in the Company’s consolidated balance sheet. The Company elected to apply certain practical expedients allowed under the new standard including (i) to use hindsight in determining the term as well as assessing the impairment of its existing leases, (ii) to not assess whether existing land easements not previously accounted for as leases are or contain leases, and (iii) to not evaluate short-term leases with terms of 12 months or less. The Company elected not to apply the package of practical expedients under the new standard which would have allowed the Company to not reassess at the date of adoption: (i) whether any existing contracts meet the definition of a lease, (ii) the lease classification for any existing leases, and (iii) the accounting for initial direct costs of any existing leases. At adoption of the new standard, the Company recorded right-of-use assets and lease liabilities for its ground leases and certain other operating leases (including hotel equipment leases and office space leases) measured at the estimated present value of the remaining minimum lease payments under the leases. Four of the Company’s ground leases that were previously classified as operating leases under Topic 840 are classified as financing leases under Topic 842. For these finance leases, effective January 1, 2019, the Company recognizes amortization expense, included in depreciation and amortization expense, and interest expense, included in interest and other expense, net, instead of operating ground lease expense, in the Company’s consolidated statements of operations. While the total expense recognized over the life of a lease is unchanged, the timing of expense recognition for these finance leases results in higher expense recognition during the earlier years of the lease and lower expense during the later years of the lease. In addition to recording operating and financing right-of-use assets and lease liabilities, the Company also reclassified at adoption of the new standard its intangible assets for below market leases and intangible liabilities for above market leases, as well as its accrued straight-line lease liabilities for its operating leases, to the beginning right-of-use assets. The Company derecognized its accrued straight-line lease liabilities related to its finance leases, which are included in the cumulative-effect adjustment noted above. The Company is also a lessor in certain retail lease agreements related to its real estate, however, there was no material change to the accounting for these leasing arrangements. See Note 9 for additional disclosures pertaining to the Company’s adoption of the new leasing standard.

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 (“U.S.”). 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 June 30, 2019, the Company owned 234 hotels with an aggregate of 30,046 rooms located in 34 states. The Company’s common shares are listed on the New York Stock Exchange (“NYSE”) 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 U.S. generally accepted accounting principles (“GAAP”) 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 Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”). Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the twelve month period ending December 31, 2019.

Use of Estimates

The preparation of the financial statements in conformity with GAAP 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 February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which replaces Leases (Topic 840), and along with subsequent amendments, provides the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). Under the new standard, lessees are required to recognize most leases on their balance sheets as right-of-use assets and lease liabilities. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. Leases with a term of 12 months or less are accounted for similarly to the previous accounting guidance under Leases (Topic 840), for operating leases. Topic 842 requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which provides entities another optional transition method, which the Company elected, to apply the new standard using the modified retrospective approach at its effective date, versus restating the prior periods presented, and recognizing a cumulative-effect adjustment to the opening balance of retained earnings for the effect of initially applying Topic 842 in the period of adoption. Consequently, an entity’s reporting for periods presented prior to adoption of the new lease requirements in the consolidated financial statements would continue in accordance with Leases (Topic 840), including disclosures.

The Company adopted Topic 842 effective January 1, 2019, electing to recognize and measure its leases prospectively at the beginning of the period of adoption through a cumulative-effect adjustment to shareholders’ equity, without restating the presentation of periods prior to the effective date, which continue to be reported in accordance with the Company’s historical accounting policy. At adoption, the Company recorded a cumulative-effect adjustment totaling approximately $5.2 million to distributions greater than net income, a component of shareholders’ equity in the Company’s consolidated balance sheet. The Company elected to apply certain practical expedients allowed under the new standard including (i) to use hindsight in determining the term as well as assessing the impairment of its existing leases, (ii) to not assess whether existing land easements not previously accounted for as leases are or contain leases, and (iii) to not evaluate short-term leases with terms of 12 months or less. The Company elected not to apply the package of practical expedients under the new standard which would have allowed the Company to not reassess at the date of adoption: (i) whether any existing contracts meet the definition of a lease, (ii) the lease classification for any existing leases, and (iii) the accounting for initial direct costs of any existing leases.

At adoption of the new standard, the Company recorded right-of-use assets and lease liabilities for its ground leases and certain other operating leases (including hotel equipment leases and office space leases) measured at the estimated present value of the remaining minimum lease payments under the leases. Four of the Company’s ground leases that were previously classified as operating leases under Topic 840 are classified as financing leases under Topic 842. For these finance leases, effective January 1, 2019, the Company recognizes amortization expense, included in depreciation and amortization expense, and interest expense, included in interest and other expense, net, instead of operating ground lease expense, in the Company’s consolidated statements of operations. While the total expense recognized over the life of a lease is unchanged, the timing of expense recognition for these finance leases results in higher expense recognition during the earlier years of the lease and lower expense during the later years of the lease. In addition to recording operating and financing right-of-use assets and lease liabilities, the Company also reclassified at adoption of the new standard its intangible assets for below market leases and intangible liabilities for above market leases, as well as its accrued straight-line lease liabilities for its operating leases, to the beginning right-of-use assets. The Company derecognized its accrued straight-line lease liabilities related to its finance leases, which are included in the cumulative-effect adjustment noted above. The Company is also a lessor in certain retail lease agreements related to its real estate, however, there was no material change to the accounting for these leasing arrangements. See Note 9 for additional disclosures pertaining to the Company’s adoption of the new leasing standard.
