Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation —The interim consolidated financial statements presented herein include all of the accounts of the Trust and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation. These reclassifications had no effect on previously reported results of operations or retained earnings. The information in these interim consolidated financial statements is unaudited but, in the opinion of management, reflects all adjustments necessary for a fair presentation of the results for the periods covered. All such adjustments are of a normal, recurring nature unless disclosed otherwise. These interim consolidated financial statements, including notes, have been prepared in accordance with the applicable rules of the Securities and Exchange Commission (“SEC”) and do not include all of the information and disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Trust’s Form 10-K for the year ended December 31, 2018 . Cash and Cash Equivalents —The Trust considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted Cash —Restricted cash includes reserves held in escrow for normal replacements of furniture, fixtures and equipment (“FF&E”), property improvement plans (each, a “PIP”), real estate taxes, and property insurance pursuant to certain requirements in the Trust’s hotel management, franchise, and loan agreements. Investments in Hotels —The Trust allocates the purchase prices of hotels acquired based on the fair value of the property, FF&E, and identifiable intangible assets acquired and the fair value of the liabilities assumed. In making estimates of fair value for purposes of allocating the purchase price, the Trust utilizes a number of sources of information that are obtained in connection with the acquisition of a hotel, including valuations performed by independent third parties and cost segregation studies. The Trust also considers information obtained about each hotel as a result of its pre-acquisition due diligence in estimating the fair value of the tangible and intangible assets acquired and liabilities assumed. Hotel acquisition costs, such as transfer taxes, title insurance, environmental and property condition reviews, and legal and accounting fees, are expensed in the period incurred if the acquisition of the hotel is determined to be an acquisition of a business; if the acquisition of the hotel is determined to be an acquisition of an asset, hotel acquisition costs are capitalized. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, generally 15 to 40 years for buildings and building improvements and three to ten years for FF&E. Leasehold improvements are amortized over the shorter of the lease term or the useful lives of the related assets. Replacements and improvements at the hotels are capitalized, while repairs and maintenance are expensed as incurred. Upon the sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the Trust’s accounts and any resulting gain or loss is recognized in the consolidated statements of operations. Intangible assets and liabilities are recorded on non-market contracts, including air rights, management, and franchise agreements, assumed as part of the acquisition of certain hotels. Above-market and below-market contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts assumed and the Trust’s estimate of the fair market contract rates for corresponding contracts measured over a period equal to the remaining non-cancelable term of the contracts assumed. No value is allocated to market contracts. Intangible assets and liabilities are amortized using the straight-line method over the remaining non-cancelable term of the related contracts. The Trust reviews its hotels for impairment whenever events or changes in circumstances indicate that the carrying values of the hotels may not be recoverable. Events or circumstances that may cause a review include, but are not limited to, adverse changes in the demand for lodging at the hotels due to declining national or local economic conditions and/or new hotel construction in markets where the hotels are located. When such conditions exist, management performs an analysis to determine if the estimated undiscounted future cash flows from operations and the proceeds from the ultimate disposition of a hotel exceed its carrying value. If the estimated undiscounted future cash flows are less than the carrying amount of the asset, an adjustment to reduce the carrying amount to the related hotel’s estimated fair market value is recorded and an impairment loss is recognized. No impairment losses have been recognized related to any hotels for the three months ended March 31, 2019 and 2018 . The Trust classifies a hotel as held for sale in the period in which it has made the decision to dispose of the hotel, a binding agreement to purchase the hotel has been signed under which the buyer has committed a significant amount of nonrefundable cash, and no significant financing contingencies exist which could cause the transaction not to be completed in a timely manner. If these criteria are met, depreciation and amortization of the hotel will cease and an impairment loss will be recognized if the fair value of the hotel, less the costs to sell, is lower than the carrying amount of the hotel. If the sale represents a strategic shift that has (or will have) a major effect on the Trust’s operations and financial results, the Trust will classify the loss, together with the related operating results, as discontinued operations in the consolidated statements of operations and will classify the related assets and liabilities as held for sale in the consolidated balance sheets. As of March 31, 2019 and December 31, 2018, the Trust had no assets held for sale or liabilities related to assets held for sale. Revenue Recognition —Revenues from operations of the hotels are recognized when goods and services are provided and the performance obligations are satisfied, net of any sales, occupancy, or other similar taxes collected from customers. Revenues consist of room sales, food and beverage sales, and other hotel revenues and are presented on a disaggregated basis on the consolidated statements of operations. Room revenue is generated through short-term contracts with customers whereby customers agree to pay a daily rate for the right to use hotel rooms for one or more nights. The Trust’s performance obligations are fulfilled at the end of each night that the customers are provided the rooms and room revenue is recognized daily at the contract rate in effect for each room night. Food and beverage revenue is generated when customers agree to pay for food and beverage at a hotel’s restaurant or bar outlets or for banquet and catering services at a hotel. The Trust’s performance obligations are fulfilled at the time that the food and beverage is provided or when the banquet facilities and related dining and other amenities (e.g., audio visual services) are provided. Other revenue (e.g., parking, marina, resort and cancellation fees, theater, leasing, spa, telephone, and gift shop sales) is recognized at the point in time or over the time period that the associated good or service is provided. Ancillary services (e.g., parking) at certain hotels are provided by third parties and the Trust assesses whether the Trust is the principal or agent in such arrangements. If the Trust is determined to be the agent, revenue is recognized based upon the commission earned from the third party on the provided service. If the Trust is determined to be the principal, revenue is recognized based upon the gross contract price of the provided service. Certain of the Trust’s hotels have retail spaces, restaurants or other spaces which the Trust leases to third parties. Lease revenue is recognized on a straight-line basis over the life of the lease and included within other revenue. Advance deposits are generally provided when a customer or group of customers provides a deposit for a future stay or banquet event at the Trust’s hotels. Advance deposits are converted to revenue when the associated goods or services are provided to the customer or when a customer with a noncancellable reservation fails to arrive for part or all of the reservation. Conversely, advance deposits are generally refundable upon guest cancellation of the related reservation within an established period of time prior to the reservation. Prepaid Expenses and Other Assets —Prepaid expenses and other assets consist of prepaid real estate taxes, prepaid insurance, deposits on hotel acquisitions and loan applications, deferred franchise costs, inventories, deferred tax assets, and other assets. Deferred Financing Costs —Deferred financing costs are recorded at cost and consist of loan fees and other costs incurred in issuing debt. Amortization of deferred financing costs is computed using a method that approximates the effective interest method over the term of the related debt and is included in interest expense in the consolidated statements of operations. Unamortized deferred financing costs are included as a direct deduction from long-term debt in the consolidated balance sheets. Derivative Instruments —From time to time, the Trust is a party to interest rate swaps, which are considered derivative instruments, in order to manage its interest rate exposure. The Trust’s interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows. The Trust records derivative instruments at fair value as either assets or liabilities and designates them as cash flow hedging instruments at inception. The Trust evaluates the hedge effectiveness of the designated cash flow hedging instruments on a quarterly basis and records the effective portion of the change in the fair value of the cash flow hedging instruments as other comprehensive income (loss). Amounts reported in accumulated other comprehensive income (loss) related to cash flow hedging instruments are reclassified to interest expense as interest payments are made on the variable-rate debt being hedged. The Trust does not enter into derivative instruments for trading or speculative purposes and monitors the financial stability and credit standing of its counterparties. Fair Value Measurements —The Trust accounts for certain assets and liabilities at fair value. In evaluating the fair value of both financial and non-financial assets and liabilities, GAAP outlines a valuation framework and creates a fair value hierarchy that distinguishes between market assumptions based on market data (observable inputs) and the reporting entity’s own assumptions about market data (unobservable inputs). The three levels of the fair value hierarchy are as follows: Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is defined as a market in which transactions occur with sufficient frequency and volume to provide pricing on an ongoing basis. Level 2 – Inputs include quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates, yield curves), and inputs that are derived principally from or corroborated by observable market data correlation or other means. Level 3 – Unobservable inputs reflect the reporting entity’s own assumptions about the pricing of an asset or liability when observable inputs are not available or when there is minimal, if any, market activity for an identical or similar asset or liability at the measurement date. Income Taxes —The Trust has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code. As a REIT, the Trust generally will not be subject to federal income tax on that portion of its net income that does not relate to any of the Trust’s TRSs, and that is currently distributed to its shareholders. The Trust’s TRSs, which lease the Trust’s hotels from the subsidiaries of the Operating Partnership owning them, are subject to federal and state income taxes. The Trust accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Valuation allowances are provided if based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Share-Based Compensation —From time to time, the Trust grants restricted share awards to employees and trustees. To date, the Trust has granted two types of restricted share awards: (1) awards that vest solely on continued employment or service (time-based awards) and (2) awards that vest based on the Trust achieving specified levels of relative total shareholder return and continued employment (performance-based awards). The Trust measures share-based compensation expense for the restricted share awards based on the fair value of the awards on the date of grant. The fair value of time-based awards is determined based on the closing price of the Trust’s common shares on the measurement date, which is generally the date of grant. The fair value of performance-based awards is determined using a Monte Carlo simulation performed by an independent third party. For time-based awards, share-based compensation expense is recognized on a straight-line basis over the life of the entire award. For performance-based awards, share-based compensation expense is recognized over the requisite service period for each award. No share-based compensation expense is recognized for awards for which employees or trustees do not render the requisite service. Earnings Per Share —Basic earnings per share is computed by dividing net income, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding, plus potentially dilutive securities, such as unvested performance-based awards, during the period. The Trust’s unvested time-based awards are entitled to receive non-forfeitable dividends, if declared. Therefore, unvested time-based awards qualify as participating securities, requiring the allocation of dividends and undistributed earnings under the two-class method to calculate basic earnings per share. The percentage of undistributed earnings allocated to the unvested time-based awards is based on the proportion of the weighted-average unvested time-based awards outstanding during the period to the total of the weighted-average common shares and unvested time-based awards outstanding during the period. No adjustment is made for shares that are anti-dilutive during the period. Segment Information —The Trust has determined that its business is conducted in one reportable segment, hotel ownership. Use of Estimates —The preparation of the interim consolidated financial statements in conformity with GAAP requires management 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 interim consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements —In February 2016, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new accounting guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on whether or not the lease is effectively a financed purchase by the lessee. The classification of the lease will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases. The Trust adopted the new accounting guidance on January 1, 2019 and applied it based on the optional transition method provided for, which allows entities to recognize a cumulative-effect adjustment to the balance sheet on the adoption date. The Trust applied certain practical expedients made available under the new accounting guidance under which the Trust was not required to reassess at the adoption date (1) whether any expired or existing contracts were or contained leases, (2) the lease classification for existing leases, (3) initial direct costs for any existing leases, and (4) whether any existing or expired land easements that were not previously accounted for as leases under the previous accounting guidance are or contain leases under the new accounting guidance. The Trust also made an accounting policy election to not recognize right-of-use assets or lease liabilities for leases with terms of 12 months or less. For its ground lease agreements and corporate office lease agreement, all of which were previously accounted for as operating leases, the Trust recognized on its consolidated balance sheet on January 1, 2019 operating lease liabilities of $72.1 million and operating lease right-of-use assets of $75.0 million , of which $3.1 million was reclassified from intangible assets related to a previously recognized favorable ground lease asset and $0.2 million was reclassified from other liabilities related to a deferred rent liability associated with the Trust’s corporate office lease agreement. See Note 4, “Leases,” for additional disclosures related to the adoption of this new accounting guidance. |
