Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Chatham Lodging Trust (“we,” “us” or the “Company”) was formed as a Maryland real estate investment trust on October 26, 2009. The Company is internally-managed and was organized to invest primarily in upscale extended-stay and premium-branded select-service hotels. The Company has elected to be treated as a real estate investment trust for federal income tax purposes ("REIT"). The Company had no operations prior to the consummation of its initial public offering ("IPO") in April 2010. The net proceeds from our share offerings are contributed to Chatham Lodging, L.P., our operating partnership (the “Operating Partnership”), in exchange for partnership interests. Substantially all of the Company’s assets are held by, and all operations are conducted through, the Operating Partnership. The Company is the sole general partner of the Operating Partnership and owns 100% of the common units of limited partnership interest in the Operating Partnership ("common units"). Certain of the Company’s executive officers hold vested and unvested long-term incentive plan units in the Operating Partnership ("LTIP units"), which are presented as non-controlling interests on our consolidated balance sheets. As of December 31, 2017 , the Company owned 40 hotels with an aggregate of 6,018 (unaudited) rooms located in 15 states and the District of Columbia (unaudited). As of December 31, 2017 , the Company also (i) held a 10.3% noncontrolling interest in a joint venture (the “NewINK JV”) with affiliates of Colony NorthStar, Inc. ("CLNS"), which was formed in the second quarter of 2014 to acquire 47 hotels from a joint venture (the "Innkeepers JV") between the Company and Cerberus Capital Management (“Cerberus”), comprising an aggregate of 6,097 (unaudited) rooms, (ii) held a 10.0% noncontrolling interest in a separate joint venture (the "Inland JV") with CLNS, which was formed in the fourth quarter of 2014 to acquire 48 hotels from Inland American Real Estate Trust, Inc. ("Inland"), comprising an aggregate of 6,401 (unaudited) rooms. The Company sold its 5.0% noncontrolling interest in a joint venture (the "Torrance JV") with Cerberus that owns the 248 -room (unaudited) Residence Inn by Marriott in Torrance, CA on December 30, 2015. We sometimes use the term, "JVs", which refers collectively to, for the period prior to December 31, 2017 , the NewINK JV, Inland JV and Torrance JV and, for the period subsequent to December 30, 2015, the NewINK JV and the Inland JV. To qualify as a REIT, the Company cannot operate its hotels. Therefore, the Operating Partnership and its subsidiaries lease the Company's wholly owned hotels to taxable REIT subsidiary lessees (“TRS Lessees”), which are wholly owned by the Company’s taxable REIT subsidiary (“TRS”) holding company. The Company indirectly (i) owns its 10.3% interest in 47 of the NewINK JV hotels, (ii) 10% interest in 48 of the Inland JV hotels and (iii) owned its 5.0% interest in the Torrance JV, which was sold on December 30, 2015 , through the Operating Partnership. All of the NewINK JV hotels and Inland JV hotels are, and the Torrance JV hotel was leased to TRS Lessees, in which the Company indirectly owns, or owned, as applicable, noncontrolling interests through its TRS holding company. Each hotel is leased to a TRS Lessee under a percentage lease that provides for rental payments equal to the greater of (i) a fixed base rent amount or (ii) a percentage rent based on hotel room revenue. The initial term of each of the TRS leases is 5 years. Lease revenue from each TRS Lessee is eliminated in consolidation. The TRS Lessees have entered into management agreements with third-party management companies that provide day-to-day management for the hotels. As of December 31, 2017 , Island Hospitality Management Inc. (“IHM”), which is 51% owned by Mr. Fisher, managed 40 of the Company’s wholly owned hotels. As of December 31, 2017 , all of the NewINK JV hotels were managed by IHM. As of December 31, 2017 , 34 of the Inland JV hotels were managed by IHM and 14 hotels were managed by Marriott International, Inc. ("Marriott"). The Torrance JV hotel was managed by Marriott.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements and related notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”). These consolidated financial statements, in the opinion of management, include all adjustments consisting of normal, recurring adjustments which are considered necessary for a fair statement of the consolidated balance sheets, consolidated statements of operations, consolidated statements of equity, and consolidated statements of cash flows for the periods presented. The consolidated financial statements include all of the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, restricted cash, hotel receivables, accounts payable and accrued expenses, distributions payable and mortgage debt. Due to their relatively short maturities, the carrying values reported in the consolidated balance sheets for these financial instruments approximate fair value except for debt, the fair value of which is separately disclosed in Note 7. Investment in Hotel Properties The Company allocates the purchase prices of hotel properties acquired based on the fair value of the acquired real estate, furniture, fixtures and equipment, identifiable intangible assets and assumed liabilities. In making estimates of fair value for purposes of allocating the purchase price, the Company utilizes a number of sources of information that are obtained in connection with the acquisition of a hotel property, including valuations performed by independent third parties and information obtained about each hotel property resulting from pre-acquisition due diligence. Hotel property acquisition costs, such as transfer taxes, title insurance, environmental and property condition reviews, and legal and accounting fees were expensed in 2016 and 2015. On January 1, 2017, the Company early adopted ASU 2017-01 "Definition of a Business" and now capitalizes these costs for asset acquisitions. The Company’s investments in hotel properties are carried at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 20 years for land improvements, 5 to 20 years for building improvements and one to ten years for furniture, fixtures and equipment. Renovations and/or replacements at the hotel properties that improve or extend the life of the assets are capitalized and depreciated over their useful lives, 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 Company’s accounts and any resulting gain or loss is recognized in the consolidated statements of operations. The Company will periodically review its hotel properties for impairment whenever events or changes in circumstances indicate that the carrying value of the hotel properties 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 properties 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 will perform an analysis to determine if the estimated undiscounted future cash flows, without interest charges, from operations and the proceeds from the ultimate disposition of a hotel property exceed its carrying value. If the estimated undiscounted future cash flows are less than the carrying amount, an adjustment to reduce the carrying amount to the related hotel property's estimated fair market value is recorded and an impairment loss recognized. For the year ended December 31, 2017 , the Company incurred an impairment loss on its Washington SHS, PA hotel (See footnote 5). For the years ended December 31, 2016 and 2015 , there were no impairment losses. For properties the Company considers held for sale, depreciation and amortization are no longer recorded and the value the properties is recorded at the lower of depreciated cost or fair value, less costs to sell. If circumstances arise that were previously considered unlikely, and, as a result, the Company decides not to sell a property previously classified as held for sale, the Company will reclassify such property as held and used. Such property is measured at the lower of its carrying amount (adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used) or fair value at the date of the subsequent decision not to sell. The Company classifies properties as held for sale when all criteria within the Financial Accounting Standards Board's ("FASB") guidance on the impairment or disposal of long-lived assets are met. As of December 31, 2017 , the Company had no hotel properties held for sale. Investment in Unconsolidated Real Estate Entities If it is determined that the Company does not have a controlling interest in a joint venture, either through its financial interest in a variable investment entity ("VIE") or in a voting interest entity, but does have the ability to exercise significant influence, the equity method of accounting is used. Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, advances to and commitments for the investee. Investment in unconsolidated real estate entities are accounted for under the equity method of accounting and the Company records its equity in earnings or losses under the hypothetical liquidation of book value (“HLBV”) method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, the Company recognizes income and loss in each period based on the change in liquidation proceeds it would receive from a hypothetical liquidation of its investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what the Company may receive in the event of an actual liquidation. In the event a basis difference is created between the carrying amount of the Company's share of partner's capital, the resulting amount is allocated based on the assets of the investee and, if assigned to depreciable or amortizable assets, then amortized as a component of income (loss) from unconsolidated real estate entities. On January 1, 2016, the Company adopted accounting guidance under Accounting Standards Codification (ASC) Topic 810, "Consolidation,” modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The guidance does not amend the existing disclosure requirements for variable interest entities ("VIEs") or voting interest model entities. The guidance, however, modified the requirements to qualify under the voting interest model. Under the revised guidance, the Operating Partnership will be a VIE of the Company. As the Operating Partnership is already consolidated in the financial statements of the Company, the identification of this entity as a VIE has no impact on the consolidated financial statements of the Company. There were no other legal entities qualifying under the scope of the revised guidance that were consolidated as a result of the adoption. In addition, there were no other voting interest entities under prior existing guidance determined to be variable interest entities under the revised guidance. The Company periodically reviews the carrying value of its investment in unconsolidated joint ventures to determine if circumstances indicate impairment to the carrying value of the investment that is other than temporary. When an impairment indicator is present, the Company will estimate the fair value of the investment. The Company’s estimate of fair value takes into consideration factors such as expected future operating income, trends and prospects, as well as other factors. This determination requires significant estimates by management, including the expected cash flows to be generated by the assets owned and operated by the joint venture. To the extent impairment has occurred and is other than temporary, the loss will be measured as the excess of the carrying amount over the fair value of the Company’s investment in the unconsolidated joint venture. As of December 31, 2017 and 2016 , no JV investments were impaired. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, demand deposits with financial institutions and short term liquid investments with an original maturity of three months or less. Cash balances in individual banks may exceed federally insurable limits. Restricted Cash Restricted cash represents purchase price deposits held in escrow for potential hotel acquisitions under contract and escrows for reserves such as reserves for capital expenditures, property taxes or insurance that are required pursuant to the Company’s loans or hotel management agreements. Restricted cash on the accompanying consolidated balance sheets at December 31, 2017 and 2016 is $27.2 million and $25.1 million , respectively. Hotel Receivables Hotel receivables consist of amounts owed by guests staying in the hotels and amounts due from business and group customers. An allowance for doubtful accounts is provided and maintained at a level believed to be adequate to absorb estimated probable losses. At December 31, 2017 and 2016 , the allowance for doubtful accounts was $0.2 million and $0.2 million , respectively. Deferred Costs Deferred costs consist of franchise agreement fees for the Company’s hotels, costs associated with potential future acquistions and loan costs related to the Company’s senior unsecured revolving credit facility. Deferred costs consisted of the following at December 31, 2017 and 2016 (in thousands): December 31, 2017 December 31, 2016 Loan costs $ 4,561 $ 4,561 Franchise fees 4,407 3,568 Other 21 — 8,989 8,129 Less accumulated amortization (4,343 ) (3,487 ) Deferred costs, net $ 4,646 $ 4,642 Loan costs are recorded at cost and amortized over the term of the loan applying the effective interest rate method. Franchise fees are recorded at cost and amortized over a straight-line basis over the term of the franchise agreements. For the years ended December 31, 2017 , 2016 and 2015 , amortization expense related to franchise fees of $0.2 million , $0.2 million and $0.2 million , respectively, is included in depreciation and amortization in the consolidated statements of operations. Amortization expense related to loan costs of $0.6 million , $0.7 million and $1.2 million for the years ended December 31, 2017 , 2016 and 2015 , respectively, is included in interest expense in the consolidated statements of operations. Mortgage Debt, net Mortgage debt, net consists of mortgage loans on certain hotel properties less the costs associated with acquiring those loans. Mortgage debt consisted of the following at December 31, 2017 and 2016 (in thousands): December 31, 2017 December 31, 2016 Mortgage debt $ 508,454 $ 532,563 Deferred financing costs (2,138 ) (2,240 ) Mortgage debt, net $ 506,316 $ 530,323 Deferred financing loan costs are recorded at cost and amortized over the term of the loan applying the effective interest rate method. For the years ended December 31, 2017 , 2016 and 2015 , amortization expense related to loan costs of $0.1 million , $0.4 million , $0.4 million , respectively, is included in interest expense in the consolidated statement of operations. Prepaid Expenses and Other Assets The Company’s prepaid expenses and other assets consist of prepaid insurance, prepaid property taxes, deposits and hotel supplies inventory. Distributions and Losses in Excess of Investments in Unconsolidated Real Estate Entities At times, certain of the Company’s investments in unconsolidated entities share of cumulative allocated losses and cash distributions received exceeds its cumulative allocated share of income and equity contributions. Although the Company typically does not make any guarantees of its investments in unconsolidated real estate entities other than certain customary non-recourse carve-out provisions, due to potential penalties along with potential upside financial returns, the Company generally intends to make any required capital contributions to maintain its ownership percentage and as such will record its share of cumulative allocated losses and cash distributions below zero. As a result, the carrying value of certain investments in unconsolidated entities is negative. Unconsolidated entities with negative carrying values are included in cash distributions and losses in excess of investments in unconsolidated entities in the Company’s consolidated balance sheets. Revenue Recognition Revenue from hotel operations is recognized when rooms are occupied and when services are provided. Revenue consists of amounts derived from hotel operations, including sales from room, meeting room, gift shop, in-room movie and other ancillary amenities. Sales, use, occupancy, and similar taxes are collected and presented on a net basis (excluded from revenue) in the accompanying consolidated statements of operations. Share-Based Compensation The Company measures compensation expense for the restricted share awards based upon the fair market value of its common shares at the date of grant. The Company measures compensation expense for the LTIP and Class A Performance units based upon the Monte Carlo approach using volatility, dividend yield and a risk free interest rate in the valuation. Compensation expense is recognized on a straight-line basis over the vesting period and is included in general and administrative expense in the accompanying consolidated statements of operations. The Company pays dividends on vested and non-vested restricted shares, except for performance-based shares, for which dividends on unvested shares are not paid until those shares are vested. The Company has also issued Class A Performance LTIP units from time to time as part of its compensation practices. Prior to vesting, holders of Class A Performance LTIP Units will not be entitled to vote their Class A Performance LTIP units. In addition, under the terms of the Class A Performance LTIP units, a holder of a Class A Performance LTIP unit will generally (i) be entitled to receive 10% of the distributions made on a common unit of the Operating Partnership during the period prior to vesting of such Class A Performance LTIP unit (the “Pre-Vesting Distributions”), (ii) be entitled, upon the vesting of such Class A Performance LTIP unit, to receive a special one-time “catch-up” distribution equal to the aggregate amount of distributions that were paid on a common unit during the period prior to vesting of such Class A Performance LTIP unit minus the aggregate amount of Pre-Vesting Distributions paid on such Class A Performance LTIP unit, and (iii) be entitled, following the vesting of such Class A Performance LTIP unit, to receive the same amount of distributions paid on a common unit of the Operating Partnership. Earnings Per Share A two class method is used to determine earnings per share. Basic earnings per share ("EPS") is computed by dividing net income (loss) available for common shareholders, adjusted for dividends on unvested share grants, by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income (loss) available for common shareholders, adjusted for dividends or distributions, on unvested share grants and LTIP units, by the weighted average number of common shares outstanding plus potentially dilutive securities such as share grants or shares issuable in the event of conversion of common units. No adjustment is made for shares that are anti-dilutive during the period. The Company’s restricted share awards and LTIP units that are subject solely to time-based vesting conditions are entitled to receive dividends or distributions on the Company's common shares or the Operating Partnership's common units, respectively, if declared. In addition, dividends on the Class A Performance LTIP units are paid the equivalent of 10% of the declared dividends on the Company's common shares. The rights to these dividends or distributions declared are non-forfeitable. As a result, the unvested restricted shares and LTIP units that are subject solely to time-based vesting conditions, as well as 10% of the unvested Class A Performance LTIP units, qualify as participating securities requiring the allocation of earnings under the two-class method to calculate EPS. The percentage of earnings allocated to these participating securities is based on the proportion of the weighted average of these outstanding participating securities to the sum of the basic weighted average common shares outstanding and the weighted average of these outstanding participating securities. Basic EPS is then computed by dividing income less earnings allocable to these participating securities by the basic weighted average number of shares outstanding. Diluted EPS is computed similar to basic EPS, except the weighted average number of shares outstanding is increased to include the effect of potentially dilutive securities. Income Taxes The Company elected to be taxed as a REIT for federal income tax purposes. In order to qualify as a REIT under the Internal Revenue Code of 1986, as amended, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income to its shareholders (which is computed without regard to the dividends paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax to the extent the Company distributes its REIT taxable income to its shareholders. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax on its REIT taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost unless the IRS grants the Company relief under certain statutory provisions. The Company leases its wholly owned hotels to TRS Lessees, which are wholly owned by the Company’s taxable REIT subsidiary (a “TRS”) which, in turn is wholly owned by the Operating Partnership. Additionally, the Company indirectly (i) owns its interest in the hotels owned by the NewINK JV ( 47 hotels) and the Inland JV ( 48 hotels) and (ii) owned its interest in the Torrance JV, which was sold on December 30, 2015 , through the Operating Partnership. All of the NewINK JV hotels and Inland JV hotels are, and the Torrance JV hotel was, leased to TRS Lessees in which the Company indirectly owns, or owned, as applicable, noncontrolling interests through its TRS holding company. The TRS is subject to federal and state income taxes and the Company accounts for taxes, where applicable, in accordance with the provisions of FASB Accounting Standards Codification 740 using the asset and liability method which recognizes deferred tax assets and liabilities for future tax consequences arising from differences between financial statement carrying amounts and income tax bases. On December 22, 2017, the TCJA was enacted. The TCJA includes a number of changes to the existing U.S. tax code, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017. Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, as a result of the TCJA being signed into law, the net deferred tax assets before valuation allowance were reduced by $0.6 million with a corresponding net adjustment to current year tax expense for the remeasurement of the Company’s U.S. net deferred tax assets. Our federal income tax expense for periods beginning in 2018 will be based on the new rate. As of December 31, 2017 , the Company is no longer subject to U.S federal income tax examinations for years before 2014 and with few exceptions to state examinations before 2014. The Company evaluates whether a tax position of the Company is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company has reviewed its tax positions for open tax years and has concluded no provisions for income taxes is required in the Company's consolidated financial statements as of December 31, 2017 . Interest and penalties related to uncertain tax benefits, if any, in the future will be recognized as operating expense. During the first quarter of 2015, management was notified that the Company's TRS was going to be examined by the State of Florida Department of Revenue for the tax years ended December 31, 2009 through 2013. The examination was closed in 2016 and no adjustments were required. Organizational and Offering Costs The Company expenses organizational costs as incurred. Offering costs, which include selling commissions, are recorded as a reduction in additional paid-in capital in shareholders’ equity as shares are sold. For offering costs incurred prior to potential share offerings, these costs are initially recorded in deferred costs on the balance sheet and then recorded as a reduction to additional paid-in capital as shares are sold through the subsequent share offering. As of December 31, 2017 and 2016 , the Company had $0 and $0 recorded in deferred costs related to deferred offering costs, respectively. Segment Information Management evaluates the Company's hotels as a single industry segment because all of the hotels have similar economic characteristics and provide similar services to similar types of customers. Recently Issued Accounting Standards On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard permits the use of either the retrospective or modified retrospective approach. In July 2015, the FASB voted to defer the effective date to January 1, 2018 with early adoption beginning January 1, 2017. We adopted the new accounting guidance on January 1, 2018 on a modified retrospective basis, which requires a cumulative effect adjustment. The Company has finalized its evaluation of each of its revenue streams under the new model and because of the short-term, day-to-day nature of the Company's hotel revenues, the pattern of revenue recognition is not expected to change and we did not recognize any cumulative effect adjustment. Furthermore, we do not expect the updated accounting guidance to materially impact the recognition of or the accounting for disposition of hotels, since we primarily dispose of hotels to third parties in exchange for cash with few contingencies. On February 25, 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases , which relates to the accounting for leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. Leases with a term of 12 months or less will be accounted for similarly to existing guidance for operating leases today. The Company is the lessee on certain air/land rights arrangements and an office lease and expects to record right of use assets and lease liabilities for these leases under the new standard. This guidance is effective for the Company on January 1, 2019, however, early adoption is permitted. The standard requires a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures. On August 26, 2016, the FASB issued ASU 2016-15 ("ASU 2016-15"), Classification of Certain Cash Receipts and Cash Payments, which clarifies and provides specific guidance on eight cash flow classification issues with an objective to reduce the current diversity in practice. This standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with earlier adoption permitted and is to be applied on a retrospective basis. The Company has certain cash payments and receipts related to debt extinguishment and distributions from equity method investments that will be affected by the new standard. The Company does not anticipate that the adoption of ASU 2016-15 will have a material impact to our consolidated financial statements. On November 17, 2016, the FASB issued ASU 2016-18 ("ASU 2016-18"), Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This standard will be effective for public companies for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and all other entities for fiscal years beginning after December 15, 2018 and is to be applied on a retrospective basis. This standard addresses presentation of restricted cash in the consolidated statements of cash flows only and will have no effect on our reported consolidated financial condition or results of operations. On January 5, 2017, the FASB issued ASU 2017-01 ("ASU 2017-01"), Definition of a Business, which will likely result in more acquisitions being accounted for as asset acquisitions across all industries, particularly real estate, pharmaceutical and oil and gas. Application of the changes would also affect the accounting for disposal transactions. The changes to the definition of a business will likely result in more of the Company's property acquisitions qualifying as asset acquisitions, which will permit capitalization of acquisition costs. This standard will be effective for public business entities with a calendar year end in 2018 and all other entities have an additional year to adopt. The Company has adopted this guidance as of 2017. The adoption did not have a material impact on our consolidated financial statements.

The sales comparison approach uses inputs of recent land sales in the respective hotel markets. The depreciated replacement cost approach uses inputs of both direct and indirect replacement costs using a nationally recognized authority on replacement cost information as well as the age, square footage and number of rooms of the respective assets. The Company incurred acquisition costs of $0.5 million and $1.5 million , respectively, during the years ended December 31, 2016 and 2015 which are included in Other charges in the Consolidated Statement of Operations. Property acquisition costs incurred during 2016 related to prior acquisitions for which final amounts were more than previously accrued. Property acquisition costs of $0.7 million were capitalized in 2017. The amount of revenue and operating income from the hotels acquired in 2017 from their respective date of acquisition through December 31, 2017 is as follows (in thousands): For the Year Ended December 31, 2017 Revenue Operating Income Hilton Garden Inn Portsmouth, NH $ 2,453 $ 1,116 Courtyard Summerville, SC $ 384 $ 152 Embassy Suites Springfield, VA $ 674 $ 161 Total $ 3,511 $ 1,429 Pro Forma Financial Information (unaudited) The following condensed pro forma financial information presents the unaudited results of operations as if the acquisition of the hotels acquired during the year ended December 31, 2015 had taken place on January 1, 2014. There were no hotels acquired in 2016. Supplemental pro forma earnings were adjusted to exclude $0.7 million of acquisition-related costs incurred in the year ended December 31, 2015. The unaudited pro forma results have been prepared for comparative purposes only and are not necessarily indicative of what actual results of operations would have been had the acquisitions taken place on January 1, 2014, nor do they purport to represent the results of operations for future periods (in thousands, except share and per share data). For the year ended December 31, 2015 Pro forma total revenue $ 292,908 Pro forma net income $ 32,137 Pro forma income per share: Basic $ 0.85 Diluted $ 0.84 Weighted average common shares outstanding Basic 37,917,871 Diluted 38,322,285 As a result of the properties being treated as acquired as of January 1, 2014, the Company assumed approximately 38,308,937 shares were issued as of January 1, 2014 to fund the acquisition of the properties. Consequently, the weighted average shares outstanding was adjusted to reflect the treatment of these assumed additional shares as issued outstanding as of the beginning of the periods presented. On August 29, 2017, the Company purchased a parcel of land in Los Angeles county for $6.5 million . On October 18, 2017, the Company entered into an agreement to acquire a additional hotel located in Summerville, SC for $20.8 million . This transaction is expected to close in the second quarter of 2018, subject to satisfactory completion of due diligence and customary closing conditions. The Company intends to fund the purchase price with available cash and borrowings under the Company's unsecured revolving credit facility.

Disposition of Hotel Properties	Disposition of Hotel Properties On December 20, 2017, the Company sold the Homewood Suites by Hilton Carlsbad (North San Diego County) for $33.0 million and recognized a gain on sale of a hotel property of $3.3 million . The buyer assumed the mortgage loan secured by the hotel of $20.0 million . Proceeds from the sale were used to repay amounts outstanding on the Company's senior unsecured revolving credit facility. This sale did not represent a strategic shift that had or will have a major effect on the Company's operations and financial results, and therefore, did not qualify to be reported as discontinued operations. For the years ended December 31, 2017 , 2016 and 2015 , the Company's Consolidated statements of operations included operating income of $2.8 million , $2.5 million and $3.4 million , respectively related to the Homewood Suites by Hilton Carlsbad (North San Diego County).

As such, the Company was required to perform a test of recoverability. This test compared the sum of the estimated future undiscounted cash flows attributable to the hotel over our remaining anticipated holding period and its expected value upon disposition to our carrying value for the hotel. The Company determined that the estimated undiscounted future cash flow attributable to the hotel did not exceed its carrying value and an impairment existed. As a result, the Company recorded a $6.7 million impairment charge in the consolidated statements of operations during the year ended December 31, 2017 . Fair value was determined based on a discounted cash flow model using our estimates of future cash flows and third-party market data, considered Level 3 inputs. We may record additional impairment charges if operating results of this hotel are materially different from our forecasts, the economy and lodging industry weakens, or we shorten our contemplated holding period.

On June 9, 2014, the Company acquired a 10.3% interest in the NewINK JV, a joint venture between affiliates of NorthStar Realty Finance Corp. ("NorthStar") and the operating partnership. The Company accounts for this investment under the equity method. NorthStar merged with Colony Capital, Inc. ("Colony") on January 10, 2017 to form a new company, CLNS, which owns an 89.7% interest and the Company owns a 10.3% interest in the NewINK JV. The value of NewINK JV assets and liabilities were adjusted to reflect estimated fair market value at the time Colony merged with NorthStar. As of December 31, 2017 and December 31, 2016 , the Company's share of partners' capital in the NewINK JV is approximately $51.8 million and $10.1 million , respectively, and the total difference between the carrying amount of the investment and the Company's share of partners' capital is approximately $58.4 million and $16.1 million (for which the basis difference related to amortizing assets is being recognized over the life of the related assets as a basis difference adjustment).

The new non-recourse loan is with Morgan Stanley Bank, N.A. The new loan bears interest at a rate of LIBOR plus a spread of 2.79% , has an initial maturity of June 7, 2019 and three one -year extension options. On June 9, 2017, the Inland JV refinanced the $817.0 million loan collateralized by the 48 hotels with a new $780.0 million non-recourse loan with Column Financial, Inc. On June 9, 2017, the Company contributed an additional $5.0 million of capital related to its share in the Inland JV to reduce the debt collateralized by the 48 hotels and fund capital reserves and deferred financing costs. The new loan bears interest at a rate of LIBOR plus a spread of 3.3% , has an initial maturity of July 9, 2019 and three one -year extension options. The Company’s ownership interests in the JVs are subject to change in the event that either the Company or CLNS calls for additional capital contributions to the respective JVs necessary for the conduct of business, including contributions to fund costs and expenses related to capital expenditures. In connection with (i) the non-recourse mortgage loan secured by the NewINK JV properties and the related non-recourse mezzanine loan secured by the membership interests in the owners of the NewINK JV properties and (ii) the non-recourse mortgage loan secured by the Inland JV properties, the Operating Partnership provided the applicable lenders with customary environmental indemnities, as well as guarantees of certain customary non-recourse carveout provisions such as fraud, material and intentional misrepresentations and misapplication of funds. In some circumstances, such as the bankruptcy of the applicable borrowers, the guarantees are for the full amount of the outstanding debt, but in most circumstances, the guarantees are capped at 15% of the debt outstanding at the time in question (in the case of the NewINK JV loans) or 20% of the debt outstanding at the time in question (in the case of the Inland JV loans). In connection with each of the NewINK JV and Inland JV loans, the Operating Partnership has entered into a contribution agreement with its JV partner whereby the JV partner is, in most cases, responsible to cover such JV partner’s pro rata share of any amounts due by the Operating Partnership under the applicable guarantees and environmental indemnities. The Company manages the JVs and will receive a promote interest in each applicable JV if it meets certain return thresholds for such JV.

The estimated fair value of the Company’s fixed rate debt as of December 31, 2017 and 2016 was $506.6 million and $516.0 million , respectively. The Company estimates the fair value of its variable rate debt by taking into account general market conditions and the estimated credit terms it could obtain for debt with a similar maturity and that is classified within level 3 of the fair value hierarchy. As of December 31, 2017 , the Company’s only variable rate debt is under its senior unsecured revolving credit facility.

The TCJA includes a number of changes to the existing U.S. tax code, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017. Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, as a result of the TCJA being signed into law, the net deferred tax assets before valuation allowance were reduced by $0.6 million with a corresponding net adjustment to current year tax expense for the remeasurement of the Company’s U.S. net deferred tax assets. Our federal income tax expense for periods beginning in 2018 will be based on the new rate. At December 31, 2017 , our TRS had a gross deferred tax asset associated with future tax deductions of $ 30.0 thousand . The tax effect of each type of temporary difference and carry forward that gives rise to the deferred tax asset as of December 31, 2017 and 2016 are as follows (in thousands): For the year ended December 31, 2017 2016 Total deferreds: Allowance for doubtful accounts $ 51 $ 59 Accrued compensation 505 627 AMT credit 30 65 Total book to tax difference in partnership (579 ) (404 ) Net operating loss 1,312 79 Valuation allowance (1,289 ) — Net deferred tax asset $ 30 $ 426 As of each reporting date, the Company's management considers new evidence, both positive and negative, that could impact management's view with regard to future realization of deferred tax assets. The Company's TRS is expecting increased taxable losses in 2018. As of December 31, 2017 , the TRS continues to recognize a full valuation allowance equal to 100% of the gross deferred tax assets, with the exception of the AMT tax credit, due to the uncertainty of the TRS's ability to utilize these deferred tax assets. Management will continue to monitor the need for a valuation allowance.

(2) The Company sold 500,000 common shares to Jeffrey H. Fisher, the Company’s Chairman, President and Chief Executive Officer (“Mr. Fisher”) in a private placement concurrent with its IPO. In January 2014, we established a $25 million dividend and reinvestment and stock purchase plan (the "Prior DRSPP"). We filed a new $50 million registration statement for the dividend reinvestment and stock purchase plan (the "New DRSPP" and together with the Prior DRSPP, the "DRSPPs") on December 28, 2017 to replace the prior expiring program. Under the DRSPPs, shareholders may purchase additional common shares by reinvesting some or all of the cash dividends received on the Company's common shares. Shareholders may also make optional cash purchases of the Company's common shares subject to certain limitations detailed in the prospectuses for the DRSPPs. As of December 31, 2017 and December 31, 2016 , respectively, we had issued 741,730 and 29,333 shares under the DRSPPs at a weighted average price of $21.00 and $21.22 per share, respectively. As of December 31, 2017 , there were common shares having a maximum aggregate sales price of approximately $50.0 million available for issuance under the New DRSPP. In January 2014, the Company established the Prior ATM Plan whereby, from time to time, the Company may publicly offer and sell up to $50 million of its common shares by means of ordinary brokers' transactions on the New York Stock Exchange (the "NYSE"), in negotiated transactions or in transactions that are deemed to be "at the market" offerings as defined in Rule 415 under the Securities Act, with Cantor Fitzgerald & Co. acting as sales agent. On January 13, 2015, the Company entered into a sales agreement with Barclays Capital Inc. (“Barclays”) to add Barclays as an additional sales agent under the Company’s Prior ATM Plan. We filed a $100 million registration statement for a new ATM program (the "ATM Plan" and together with the Prior ATM Plan, the "ATM Plans") on December 28, 2017 to replace the prior program.

Preferred Shares The Company is authorized to issue up to 100,000,000 preferred shares, $.01 par value per share. No preferred shares were outstanding at December 31, 2017 and 2016 . Operating Partnership Units Holders of common units in the Operating Partnership, if and when issued, will have certain redemption rights, which will enable the unit holders to cause the Operating Partnership to redeem their units in exchange for, at the Company’s option, cash per unit equal to the market price of the Company’s common shares at the time of redemption or for the Company’s common shares on a one-for-one basis. The number of shares issuable upon exercise of the redemption rights will be adjusted upon the occurrence of share splits, mergers, consolidations or similar pro-rata share transactions, which otherwise would have the effect of diluting the ownership interests of limited partners or shareholders. As of December 31, 2017 and 2016 , there were no Operating Partnership common units held by unaffiliated third parties. At December 31, 2017 and 2016 , an aggregate of 257,775 and 257,775 LTIP units, respectively, a special class of operating partnership units, were held by executive officers. The LTIP units receive per unit distributions equal to the per share distribution paid on common shares. Upon the closing of the Company's equity offering on September 30, 2013, the Company determined that a revaluation event occurred, as defined in the Internal Revenue Code of 1986, as amended (the "Code"), and 26,250 LTIP units awarded in 2010 and held by one of the officers of the Company achieved full parity with the common units of the Operating Partnership with respect to liquidating distributions and all other purposes. 100% of these LTIP units have vested as of December 31, 2017 . As of June 4, 2014, the Company determined that a revaluation event occurred, as defined in the Code, and 231,525 LTIP units awarded in 2010 and held by the other two officers of the Company achieved full parity with the common units of the Operating Partnership with respect to liquidating distributions and all other purposes. 100% of the units have reached parity as of December 31, 2017 . Accordingly, these LTIP units awarded in 2010 are allocated their pro-rata share of the Company's net income. At December 31, 2017 and 2016 , an aggregate of 356,933 and 222,585 Class A Performance LTIP units, respectively, were held by executive officers. Prior to vesting, holders of Class A Performance LTIP Units will not be entitled to vote their Class A Performance LTIP units. In addition, under the terms of the Class A Performance LTIP units, a holder of a Class A Performance LTIP unit will generally (i) be entitled to receive 10% of the distributions made on a common unit of the Operating Partnership during the period prior to vesting of such Class A Performance LTIP unit (the “Pre-Vesting Distributions”), (ii) be entitled, upon the vesting of such Class A Performance LTIP unit, to receive a special one-time “catch-up” distribution per LTIP unit equal to the aggregate amount of distributions that were paid on a common unit during the period prior to vesting of such Class A Performance LTIP unit minus the aggregate amount of Pre-Vesting Distributions paid on such Class A Performance LTIP unit, and (iii) be entitled, following the vesting of such Class A Performance LTIP unit, to receive the same amount of distributions paid on a common unit of the Operating Partnership. As of June 1 2017, the Company determined that a revaluation event occurred, as defined in the Code, and 118,791 and 128,859 LITP units awarded in 2016 and 2017, respectively, and held by six officers of the Company had achieved full parity with the common units of the Operating Partnership with respect to liquidating distributions and all other purposes. As of December 31, 2017 , 33% and 0% of these units awarded in 2016 and 2017, respectively, have vested. Accordingly, these LTIP units awarded in 2016 and 2017 are allocated their pro-rata share of the Company's net income. At December 31, 2017 and 2016 , an aggregate of 162,540 and 72,966 2016 Time-Based LTIP Unit Awards, respectively, a special class of operating partnership units, were held by executive officers. The 2017 Time-Based LTIP Unit Awards will vest ratably on each of March 1, 2018, March 1, 2019 and March 1, 2020. The 2016 Time-Based LTIP Unit Awards will vest ratably on each of January 28, 2017, January 28, 2018 and January 28, 2019. Prior to vesting, a holder is entitled to receive distributions on and to vote the LTIP Units that comprise the 2016 Time-Based LTIP Unit Awards.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The two class method is used to determine earnings per share because unvested restricted shares and unvested LTIP units are considered to be participating shares. The LTIP units held by the non-controlling interest holders, which may be converted to common shares of beneficial interest, have been excluded from the denominator of the diluted earnings per share calculation as there would be no effect on the amounts since limited partners' share of income or loss would also be added back to net income or loss. Unvested restricted shares, unvested long-term incentive plan units and unvested Class A Performance LTIP units that could potentially dilute basic earnings per share in the future would not be included in the computation of diluted loss per share for the periods where a loss has been recorded, because they would have been anti-dilutive for the periods presented. The following is a reconciliation of the amounts used in calculating basic and diluted net income per share (in thousands, except share and per share data): For the year ended December 31, 2017 2016 2015 Numerator: Net income $ 29,478 $ 31,483 $ 32,966 Dividends paid on unvested shares and LTIP units (235 ) (189 ) (151 ) Net income attributable to common shareholders $ 29,243 $ 31,294 $ 32,815 Denominator: Weighted average number of common shares - basic 39,859,143 38,299,067 37,917,871 Effect of dilutive securities: Unvested shares 253,123 183,808 404,414 Weighted average number of common shares - diluted 40,112,266 38,482,875 38,322,285 Basic income per Common Share: Net income attributable to common shareholders per weighted average common share $ 0.73 $ 0.82 $ 0.87 Diluted income per Common Share: Net income attributable to common shareholders per weighted average common share $ 0.73 $ 0.81 $ 0.86

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plan	Equity Incentive Plan The Company maintains its Equity Incentive Plan to attract and retain independent trustees, executive officers and other key employees and service providers. The plan provides for the grant of options to purchase common shares, share awards, share appreciation rights, performance units, and other equity-based awards. The plan was amended and restated as of May 17, 2013 to increase the maximum number of shares available under the plan to 3,000,000 shares. Share awards under this plan generally vest over three to five years, though compensation for the Company’s independent trustees includes shares granted that vest immediately. The Company pays dividends on unvested shares and units, except for performance-based shares and outperformance based units, for which dividends on unvested performance-based shares and units are accrued and not paid until those shares or units vest. Class A Performance LTIP units, for which dividends are paid based on 10% of the declared amount until the Class A Performance LTIP units vest, at which time the remaining 90% of the dividends is paid. Certain awards may provide for accelerated vesting if there is a change in control. As of December 31, 2017 , there were 1,871,942 common shares available for issuance under the Equity Incentive Plan. Restricted Share Awards A summary of the restricted shares granted to executive officers that have not fully vested pursuant to the Equity Incentive Plan as of December 31, 2017 are: Award Type Award Date Total Shares Granted Vested as of December 31, 2017 2014 Time-based Awards 1/31/2014 48,213 48,213 2014 Performance-based Awards 1/31/2014 38,805 12,935 2015 Time-based Awards 1/30/2015 40,161 26,774 2015 Performance-based Awards 1/30/2015 36,144 — 2015 Time-based Awards 6/1/2015 8,949 5,966 2017 Restricted Board Awards 1/11/2017 5,000 — Time-based shares will vest over a three -year period. The performance-based shares will be issued and vest over a three -year period only if and to the extent that long-term performance criteria established by the Board of Trustees are met and the recipient remains employed by the Company through the vesting date. The Company measures compensation expense for time-based share awards based upon the fair market value of its common shares at the date of grant. For the performance-based shares granted in 2014 and 2015, compensation expense is based on a valuation of $13.17 and $ 21.21 , respectively, per performance share granted, which takes into account that some or all of the awards may not vest if long-term performance criteria are not met during the vesting period. The 2014 performance-based shares did not meet the vesting criteria for 2015 or 2016 causing the last two tranches of the 2014 performance grants not to be eligible for future vesting. Neither of the first two tranches of the 2015 performance grants vested. The grant date fair values of the performance-based share awards were determined using a Monte Carlo simulation method with the following assumptions: Performance Award Grant Date Volatility Dividend Yield Risk Free Interest Rate 1/31/2014 27 % — % 0.71 % 1/30/2015 29 % — % 0.84 % Compensation expense is recognized on a straight-line basis over the vesting period and is included in general and administrative expense in the accompanying consolidated statements of operations. The Company pays dividends on unvested time-based restricted shares. Dividends for performance-based shares are accrued and paid annually only if and to the extent that long-term performance criteria established by the Board of Trustees are met and the recipient remains employed by the Company on the vesting date. A summary of the Company’s restricted share awards for the years ended December 31, 2017 , 2016 and 2015 is as follows: December 31, 2017 December 31, 2016 December 31, 2015 Number of Shares Weighted - Average Grant Date Fair Value Number of Shares Weighted - Average Grant Date Fair Value Number of Shares Weighted - Average Grant Date Fair Value Non-vested at beginning of the period 110,825 $ 22.05 170,480 $ 21.38 179,641 $ 14.92 Granted 5,000 20.20 — — 85,254 26.59 Vested (32,441 ) 25.77 (59,655 ) 20.14 (94,415 ) 13.80 Forfeited (25,870 ) 13.17 — — — — Unvested at end of the period 57,514 $ 23.78 110,825 $ 22.05 170,480 $ 21.38 As of December 31, 2017 and 2016 , there were $0.1 million and $0.9 million , respectively, of unrecognized compensation costs related to restricted share awards. As of December 31, 2017 , these costs were expected to be recognized over a weighted–average period of approximately 1.1 years . For the years ended December 31, 2017 , 2016 and 2015 , the Company recognized approximately $0.8 million , $1.3 million and $1.6 million , respectively, of expense related to the restricted share awards. This expense is included in general and administrative expenses in the accompanying consolidated statements of operations. Long-Term Incentive Plan Units LTIP units are a special class of partnership interests in the Operating Partnership which may be issued to eligible participants for the performance of services to or for the benefit of the Company. Under the Equity Incentive Plan, each LTIP unit issued is deemed equivalent to an award of one common share thereby reducing the availability for other equity awards on a one -for-one basis. The Company does not receive a tax deduction for the value of any LTIP units granted to employees. LTIP units, whether vested or not, receive the same per unit profit distributions as other outstanding units of the Operating Partnership, which profit distribution will generally equal per share dividends on the Company’s common shares. Initially, LTIP units have a capital account balance of zero, and do not have full parity with common units with respect to liquidating distributions. The Operating Partnership will revalue its assets upon the occurrence of certain specified events and any increase in valuation will be allocated first to the holders of LTIP units to equalize the capital accounts of such holders with the capital accounts of the Operating Partnership unit holders. If such parity is reached, vested LTIP units may be converted by the holder, at any time, into an equal number of common units in the Operating Partnership, which may be redeemed, at the option of the holder, for cash or at the Company’s option an equivalent number of the Company’s common shares. A summary of the Company's LTIP Unit awards for the years ended years ended December 31, 2017 , 2016 and 2015 is as follows: December 31, 2017 December 31, 2016 December 31, 2015 Number of Shares Weighted - Average Grant Date Fair Value Number of Shares Weighted - Average Grant Date Fair Value Number of Shares Weighted - Average Grant Date Fair Value Non-vested at beginning of the period 295,551 $ 14.36 183,300 $ 14.13 51,555 $ 15.18 Granted 223,922 19.20 112,251 14.73 183,300 14.13 Vested (37,417 ) 14.73 — — (51,555 ) (15.18 ) Non-vested at end of period 482,056 $ 16.58 295,551 $ 14.36 183,300 $ 14.13 On April 21, 2010, the Company’s Operating Partnership granted 246,960 LTIP units to the Company’s executive officers pursuant to the Equity Incentive Plan, all of which are accounted for in accordance with FASB Codification Topic (“ASC”) 718, “Stock Compensation”. On September 9, 2010, the Company’s Operating Partnership granted 26,250 LTIP units to the Company’s then new Chief Financial Officer and 15,435 LTIP units granted to the Company’s former Chief Financial Officer were forfeited. These LTIP units vested ratably over a five year period beginning on the date of grant. All of these LTIP units have vested. On June 1, 2015, the Company's Operating Partnership granted 183,300 Class A Performance LTIP units, as recommended by the Compensation Committee of the Board (the “Compensation Committee”), pursuant to a long-term, multi-year performance plan (the “Outperformance Plan”). The awards granted pursuant to the Outperformance Plan are subject to two separate performance measurements, with 60% of the award (the "Absolute Award") based solely on the Company's total shareholder return ("TSR") (the "Absolute TSR Component") and 40% of the award (the "Relative Award") measured by the Company's TSR (the "Relative TSR Component") relative to the other companies (the "Index Companies") that were constituents of the SNL US REIT Hotel Index (the "Index") during the entire measurement period. Under the Absolute TSR Component, 37.5% of the Absolute Award is earned if the Company achieves a 25% TSR over the measurement period. That percentage increases on a linear basis with the full Absolute Award being earned at a 50% TSR over the measurement period. For TSR performance below 25% , no portion of the Absolute Award will be earned. Under the Relative TSR Component, 37.5% of the Relative Award is earned if the Company is at the 50 th percentile of the Index Companies at the end of the measurement period. That percentage increases on a linear basis with the full Relative Award earned if the Company is at the 75 th percentile of the Index Companies at the end of the measurement period. If the Company is below the 50 th percentile of the Index Companies at the end of the measurement period, no portion of the Relative Award will be earned. Compensation expense is based on an estimated value of $14.13 per Class A Performance LTIP unit, which takes into account that some or all of the awards may not vest if long-term performance criteria are not met during the vesting period. Awards earned under the Outperformance Plan will vest 50% at the end of the three -year measurement period on June 1, 2018 and 25% each on the one -year and two -year anniversaries of the end of the three -year measurement period, or June 1, 2019 and 2020, respectively, and provided that the recipient remains employed by the Company through the vesting dates. In the event of a Change in Control (as defined in the executive officers’ employment agreements), Outperformance Plan awards will be earned contingent upon the attainment of a pro rata TSR hurdle for the Absolute Award and achievement of the relative TSR percentile for the Relative Award based upon the in-place formula and using the Change of Control as the end of measurement period. Vesting continues to apply to awards earned upon a Change of Control, subject to full acceleration upon termination without cause or resignation for good reason within 18 months of the Change of Control. Prior to vesting, holders of Class A Performance LTIP Units will not be entitled to vote their Class A Performance LTIP units. In addition, under the terms of the Class A Performance LTIP units, a holder of a Class A Performance LTIP unit will generally (i) be entitled to receive 10% of the distributions made on a common unit of the Operating Partnership during the period prior to vesting of such Class A Performance LTIP unit (the “Pre-Vesting Distributions”), (ii) be entitled, upon the vesting of such Class A Performance LTIP unit, to receive a special one-time “catch-up” distribution equal to the aggregate amount of distributions that were paid on a common unit during the period prior to vesting of such Class A Performance LTIP unit minus the aggregate amount of Pre-Vesting Distributions paid on such Class A Performance LTIP unit, and (iii) be entitled, following the vesting of such Class A Performance LTIP unit, to receive the same amount of distributions paid on a common unit of the Operating Partnership. Time-Based Equity Incentive Awards On January 28, 2016, the Company’s Operating Partnership, upon the recommendation of the Compensation Committee, granted 72,966 time-based awards (the “2016 Time-Based LTIP Unit Award”). The grants were made pursuant to award agreements that provide for time-based vesting (the "LTIP Unit Time-Based Vesting Agreement"). The 2016 Time-Based LTIP Unit Awards will vest ratably on each of January 28, 2017, January 28, 2018 and January 28, 2019 (provided that the recipient remains employed by the Company through the applicable vesting date , subject to acceleration of vesting in the event of the recipient’s death, disability, termination without cause or resignation with good reason, or in the event of a change of control of the Company ). Prior to vesting, a holder is entitled to receive distributions on and to vote the LTIP Units that comprise the 2016 Time-Based LTIP Unit Awards. Compensation expense is based on an estimated value of $16.69 per 2016 Time-Based LTIP Unit Award. On March 1, 2017, the Company's Operating Partnership, upon recommendation of the Compensation Committee, granted 89,574 time-based awards (the "2017 Time-Based LTIP Unit Awards"). The grants were made pursuant to the award agreements that provided for time-based vesting. The 2017 Time-Based LTIP Unit Awards will vest ratably on each March 1, 2018, March 1, 2019 and March 1, 2020 (provided that the recipient remains employed by the Company through the applicable vesting date, subject to acceleration of vesting in the event of the recipient's death, disability, termination without cause or resignation with good reason, or in the event of a change in control of the Company). Prior to vesting, a holder is entitled to receive distributions on the LTIP Units that comprise the 2017 Time-Based LTIP Unit Awards. Compensation expense is based on an estimated value of $18.53 per 2017 Time-Based LTIP Unit Award. Performance-Based Equity Incentive Awards On January 28, 2016, the Company’s Operating Partnership, upon the recommendation of the Compensation Committee, also granted 39,285 performance-based awards (the "2016 Performance-Based LTIP Unit Awards"). The grants were made pursuant to award agreements that provide for performance-based vesting (the "LTIP Unit Performance-Based Vesting Agreement"). The 2016 Performance-Based LTIP Unit Awards are comprised of Class A Performance LTIP Units of the Operating Partnership (“Class A Performance LTIP Units”) that will vest only if and to the extent that (i) the Company achieves certain long-term performance criteria established by the Compensation Committee and set forth in the LTIP Unit Performance-Based Vesting Agreement and (ii) the recipient remains employed by the Company through the applicable vesting date, subject to acceleration of vesting in the event of the recipient’s death, disability, termination without cause or resignation with good reason, or in the event of a change of control of the Company. Compensation expense is based on an estimated value of $11.09 per 2016 Performance-Based LTIP Unit Awards, which takes into account that some or all of the awards may not vest if long-term performance criteria are not met during the vesting period. The 2016 Performance-Based LTIP Unit Awards shall vest based on the following: (a) The number of Class A Performance LTIP Units that most nearly equals (but does not exceed) one-third of the Class A Performance LTIP Units issued pursuant to such 2016 Performance-Based LTIP Unit Award shall vest on January 28, 2017, if the Total Shareholder Return for the 12-month period beginning January 28, 2016 and ending on January 27, 2017 is 8% or more. These Performance-Based LTIP Unit Awards vested on January 27, 2017. (b) The number of Class A Performance LTIP Units that most nearly equals (but does not exceed) one-third of the Class A Performance LTIP Units issued pursuant to such 2016 Performance-Based LTIP Unit Award shall vest on January 28, 2018, if the Total Shareholder Return for the 12-month period beginning January 28, 2017 and ending on January 27, 2018 is 8% or more. (c) The number of Class A Performance LTIP Units that most nearly equals (but does not exceed) one-third of the Class A Performance LTIP Units issued pursuant to such 2016 Performance-Based LTIP Unit Award shall vest on January 28, 2019, if the Total Shareholder Return for the 12-month period beginning January 28, 2018 and ending on January 27, 2019 is 8% or more. (d) All of the Class A Performance LTIP Units issued pursuant to such 2016 Performance-Based LTIP Unit Award (less any Class A Performance LTIP Units that previously vested under paragraphs (a), (b) or (c) above), shall vest on January 28, 2019, if the average Total Shareholder Return for the 36-month period ending on January 27, 2019 is 8% or more. For purposes of the 2016 Performance-Based LTIP Unit Awards, "Total Shareholder Return" means, with respect to the measurement periods described in paragraphs (a), (b), (c) and (d) above, the total percentage return per common share of the Company based on the closing price of the Company’s common shares on the New York Stock Exchange (“NYSE”) on the last trading day immediately preceding the first day of the applicable measurement period compared to the closing price of the Company’s common shares on the NYSE on the last trading day of such measurement period and assuming contemporaneous reinvestment in Company common shares of all dividends and other distributions at the closing price of the Company’s common shares on the date such dividend or other distribution was paid. On March 1, 2017, the Company's Operating Partnership, upon the recommendation of the Compensation Committee, also granted 134,348 performance-based awards (the "2017 Performance-Based LTIP Unit Awards"). The grants were made pursuant to award agreements that provide for performance-based vesting. The 2017 Performance-Based LTIP Unit Awards are comprised of Class A Performance LTIP Units that will vest only if and to the extent that (i) the Company achieves certain long-term performance criteria established by the Compensation Committee and (ii) the recipient remains employed by the Company through the vesting date, subject to acceleration of vesting in the event of the recipient's death, disability, termination without cause or resignation with good reason, or in the event of a change of control of the Company. Compensation expense is based on an estimated value of $19.65 per 2017 Performance-Based LTIP Unit Award, which takes into account that some or all of the awards may not vest if long-term performance criteria are not met during the vesting period. The 2017 Performance-Based LTIP Unit Awards may be earned based on the Company's relative TSR performance for the three-year period beginning on March 1, 2017 and ending on February 28, 2020. The 2017 Performance-Based LTIP Unit Awards, if earned, will be paid out between 50% and 150% of target value as follows: Relative TSR Hurdles (Percentile) Payout Percentage Threshold 25th 50% Target 50th 100% Maximum 75th 150% Payouts at performance levels in between the hurdles will be calculated by straight-line interpolation. The TSR hurdles are based on the Company's performance relative to the average TSR for the companies included in the SNL US Hotel REIT Index. TSR will be calculated to include share price appreciation plus dividends assuming the reinvestment of dividends as calculated by a third-party such as SNL Financial. The Company will estimate the aggregate compensation cost to be recognized over the service period determined as of the grant date under ASC 718, excluding the effect of estimate forfeitures, and will calculate the value at the grant date based on the probable outcome of the performance conditions. A holder of a Class A Performance LTIP Unit will generally (i) only be entitled, during the period prior to the vesting of such Class A Performance LTIP Unit, to receive 10% of the distributions made on a common unit of limited partnership interest (“Common Unit”) in the Operating Partnership (the “Pre-Vesting Distributions”), and (ii) be entitled, upon the vesting of such Class A Performance LTIP Unit, to a special one-time “catch-up” distribution equal to the aggregate amount of distributions that were paid on a Common Unit during the period prior to vesting of such Class A Performance LTIP Unit minus the aggregate amount of Pre-Vesting Distributions paid on such Class A Performance LTIP Unit. In addition, prior to the vesting of a Class A Performance LTIP Unit, the holder of such Class A Performance LTIP Unit will not be entitled to vote on such Class A Performance LTIP Unit. The LTIP units' fair value was determined using a Monte Carlo approach. In determining the discounted value of the LTIP units, the Company considered the inherent uncertainty that the LTIP units would never reach parity with the other common units of the Operating Partnership and thus have an economic value of zero to the grantee. Additional factors considered in reaching the assumptions of uncertainty included discounts for illiquidity; expectations for future dividends; limited or no operations history as of the date of the grant; significant dependency on the efforts and services of our executive officers and other key members of management to implement the Company's business plan; available acquisition opportunities; and economic environment and conditions. The grant date fair value of the performance LTIP awards were determined using a Monte Carlo simulation method with the following assumptions (based on the three year risk free U.S. Treasury yield over the measurement period of the LTIP awards): Grant Date Volatility Dividend Yield Risk Free Interest Rate Discount Outperformance Plan 6/1/2015 26% 4.5% 0.95% —% 2016 Time-Based LTIP Unit Awards 1/28/16 28% —% 0.79% 7.5% 2016 Performance-Based LTIP Unit Awards 1/28/16 30% 5.8% 1.13% —% 2017 Time-Based LTIP Unit Awards 3/1/17 24% —% 0.92% 7.5% 2017 Performance-Based LTIP Unit Awards 3/1/17 25% 5.8% 1.47% —% The Company recorded $2.5 million , $1.2 million and $0.7 million in compensation expense related to the LTIP units for years ended December 31, 2017 , 2016 and 2015 , respectively. As of December 31, 2017 and 2016 , there was $4.4 million and $2.6 million , respectively, of total unrecognized compensation cost related to LTIP units. This cost is expected to be recognized over approximately 1.9 years , which represents the weighted average remaining vesting period of the LTIP units. As of June 1, 2017, the Company determined that a revaluation event occurred as defined in the Code, and 112,251 and 223,922 LTIP units awarded in 2016 and 2017, respectively, and held by six officers of the Company had achieved full parity with the common units of the Operating Partnership with respect to liquidating distributions and all other purposes. As of December 31, 2017 , 33% and 0% of these units awarded in 2016 and 2017, respectively, have vested. Accordingly, these LTIP units awarded in 2010, 2016 and 2017 were allocated their pro-rata share of the Company's net income. The cumulative number of LTIPs that have achieved full parity are 593,948 of the total LTIPs granted of 777,248 . Board of Trustee Share Compensation For 2017, 2016 and 2015, each independent trustee was compensated $0.1 million for their services. Each trustee may elect to receive up to 100% of their compensation in the form of shares, but must receive at least 50% in the form of shares. In January 2017 , 2016 and 2015 , the Company issued 23,980 , 26,488 and 16,542 common shares, respectively, to its independent trustees as compensation for services performed in 2016 , 2015 and 2014 , respectively. The quantity of shares was calculated based on the average of the closing price for the Company’s common shares on the NYSE for the last ten trading days preceding the reporting date. On January 16, 2018, the Company distributed 21,670 common shares to its independent trustees for services performed in 2017 .

Commitments and Contingencies	Commitments and Contingencies Litigation The nature of the operations of the Company's hotels exposes those hotels, the Company and the Operating Partnership to the risk of claims and litigation in the normal course of their business. IHM is currently a defendant in a class action lawsuit pending in the Santa Clara County Superior Court. The class action lawsuit was filed on October 21, 2016 under the title Ruffy, et al, v. Island Hospitality Management, LLC, et al. Case No. 16-CV-301473. The class action relates to hotels operated by IHM in the state of California and owned by affiliates of the Company and the NewINK JV, and/or certain third parties. The complaint alleges various wage and hour law violations based on alleged misclassification of certain hotel managerial staff and violation of certain California statutes regarding incorrect information contained on employee paystubs. The plaintiffs seek injunctive relief, money damages, penalties, and interest. None of the potential classes has been certified and we are defending our case vigorously. As of December 31, 2017, included in accounts payable and expenses is $0.2 million which represents an estimate of the Company’s exposure to the litigation and is also its estimated maximum possible loss that the Company may incur. Hotel Ground Rent The Courtyard Altoona hotel is subject to a ground lease with an expiration date of April 30, 2029 with an extension option by the Company of up to 12 additional terms of five years each. Monthly payments are determined by the quarterly average room occupancy of the hotel. Rent currently is equal to approximately $8,000 per month when monthly occupancy is less than 85% and can increase up to approximately $20,000 per month if occupancy is 100% , with minimum rent increased by two and one-half percent ( 2.5% ) on an annual basis. The Residence Inn San Diego Gaslamp hotel is subject to a ground lease with an expiration of January 31, 2065 with an extension option by the Company of up to three additional terms of ten years each. Monthly payments are currently approximately $40,000 per month and increase 10% every 5 years. The hotel is subject to supplemental rent payments annually calculated as 5% of gross revenues during the applicable lease year, minus 12 times the monthly base rent scheduled for the lease year. At the Residence Inn New Rochelle hotel is subject to an air rights lease and garage lease that each expires on December 1, 2104 . The lease agreements with the City of New Rochelle cover the space above the parking garage that is occupied by the hotel as well as 128 parking spaces in a parking garage that is attached to the hotel. The annual base rent for the garage lease is the hotel’s proportionate share of the city’s adopted budget for the operations, management and maintenance of the garage and established reserves to fund the cost of capital repairs.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements and related notes have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”). These consolidated financial statements, in the opinion of management, include all adjustments consisting of normal, recurring adjustments which are considered necessary for a fair statement of the consolidated balance sheets, consolidated statements of operations, consolidated statements of equity, and consolidated statements of cash flows for the periods presented. The consolidated financial statements include all of the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, restricted cash, hotel receivables, accounts payable and accrued expenses, distributions payable and mortgage debt. Due to their relatively short maturities, the carrying values reported in the consolidated balance sheets for these financial instruments approximate fair value except for debt, the fair value of which is separately disclosed in Note 7.
Investment in Hotel Properties	Investment in Hotel Properties The Company allocates the purchase prices of hotel properties acquired based on the fair value of the acquired real estate, furniture, fixtures and equipment, identifiable intangible assets and assumed liabilities. In making estimates of fair value for purposes of allocating the purchase price, the Company utilizes a number of sources of information that are obtained in connection with the acquisition of a hotel property, including valuations performed by independent third parties and information obtained about each hotel property resulting from pre-acquisition due diligence. Hotel property acquisition costs, such as transfer taxes, title insurance, environmental and property condition reviews, and legal and accounting fees were expensed in 2016 and 2015. On January 1, 2017, the Company early adopted ASU 2017-01 "Definition of a Business" and now capitalizes these costs for asset acquisitions. The Company’s investments in hotel properties are carried at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 20 years for land improvements, 5 to 20 years for building improvements and one to ten years for furniture, fixtures and equipment. Renovations and/or replacements at the hotel properties that improve or extend the life of the assets are capitalized and depreciated over their useful lives, 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 Company’s accounts and any resulting gain or loss is recognized in the consolidated statements of operations. The Company will periodically review its hotel properties for impairment whenever events or changes in circumstances indicate that the carrying value of the hotel properties 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 properties 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 will perform an analysis to determine if the estimated undiscounted future cash flows, without interest charges, from operations and the proceeds from the ultimate disposition of a hotel property exceed its carrying value. If the estimated undiscounted future cash flows are less than the carrying amount, an adjustment to reduce the carrying amount to the related hotel property's estimated fair market value is recorded and an impairment loss recognized. For the year ended December 31, 2017 , the Company incurred an impairment loss on its Washington SHS, PA hotel (See footnote 5). For the years ended December 31, 2016 and 2015 , there were no impairment losses. For properties the Company considers held for sale, depreciation and amortization are no longer recorded and the value the properties is recorded at the lower of depreciated cost or fair value, less costs to sell. If circumstances arise that were previously considered unlikely, and, as a result, the Company decides not to sell a property previously classified as held for sale, the Company will reclassify such property as held and used. Such property is measured at the lower of its carrying amount (adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used) or fair value at the date of the subsequent decision not to sell. The Company classifies properties as held for sale when all criteria within the Financial Accounting Standards Board's ("FASB") guidance on the impairment or disposal of long-lived assets are met.
Investment in Unconsolidated Real Estate Entities	Investment in Unconsolidated Real Estate Entities If it is determined that the Company does not have a controlling interest in a joint venture, either through its financial interest in a variable investment entity ("VIE") or in a voting interest entity, but does have the ability to exercise significant influence, the equity method of accounting is used. Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, advances to and commitments for the investee. Investment in unconsolidated real estate entities are accounted for under the equity method of accounting and the Company records its equity in earnings or losses under the hypothetical liquidation of book value (“HLBV”) method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, the Company recognizes income and loss in each period based on the change in liquidation proceeds it would receive from a hypothetical liquidation of its investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what the Company may receive in the event of an actual liquidation. In the event a basis difference is created between the carrying amount of the Company's share of partner's capital, the resulting amount is allocated based on the assets of the investee and, if assigned to depreciable or amortizable assets, then amortized as a component of income (loss) from unconsolidated real estate entities. On January 1, 2016, the Company adopted accounting guidance under Accounting Standards Codification (ASC) Topic 810, "Consolidation,” modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The guidance does not amend the existing disclosure requirements for variable interest entities ("VIEs") or voting interest model entities. The guidance, however, modified the requirements to qualify under the voting interest model. Under the revised guidance, the Operating Partnership will be a VIE of the Company. As the Operating Partnership is already consolidated in the financial statements of the Company, the identification of this entity as a VIE has no impact on the consolidated financial statements of the Company. There were no other legal entities qualifying under the scope of the revised guidance that were consolidated as a result of the adoption. In addition, there were no other voting interest entities under prior existing guidance determined to be variable interest entities under the revised guidance. The Company periodically reviews the carrying value of its investment in unconsolidated joint ventures to determine if circumstances indicate impairment to the carrying value of the investment that is other than temporary. When an impairment indicator is present, the Company will estimate the fair value of the investment. The Company’s estimate of fair value takes into consideration factors such as expected future operating income, trends and prospects, as well as other factors. This determination requires significant estimates by management, including the expected cash flows to be generated by the assets owned and operated by the joint venture. To the extent impairment has occurred and is other than temporary, the loss will be measured as the excess of the carrying amount over the fair value of the Company’s investment in the unconsolidated joint venture.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, demand deposits with financial institutions and short term liquid investments with an original maturity of three months or less. Cash balances in individual banks may exceed federally insurable limits.
Restricted Cash	Restricted Cash Restricted cash represents purchase price deposits held in escrow for potential hotel acquisitions under contract and escrows for reserves such as reserves for capital expenditures, property taxes or insurance that are required pursuant to the Company’s loans or hotel management agreements.
Hotel Receivables	Hotel Receivables Hotel receivables consist of amounts owed by guests staying in the hotels and amounts due from business and group customers. An allowance for doubtful accounts is provided and maintained at a level believed to be adequate to absorb estimated probable losses.
Deferred Costs	Deferred Costs Deferred costs consist of franchise agreement fees for the Company’s hotels, costs associated with potential future acquistions and loan costs related to the Company’s senior unsecured revolving credit facility. Loan costs are recorded at cost and amortized over the term of the loan applying the effective interest rate method. Franchise fees are recorded at cost and amortized over a straight-line basis over the term of the franchise agreements.
Mortgage Debt, net	Mortgage Debt, net Mortgage debt, net consists of mortgage loans on certain hotel properties less the costs associated with acquiring those loans.
Prepaid Expenses And Other Assets	Prepaid Expenses and Other Assets The Company’s prepaid expenses and other assets consist of prepaid insurance, prepaid property taxes, deposits and hotel supplies inventory.
Distributions and Losses in Excess of Investments in Unconsolidated Real Estate Entities	Distributions and Losses in Excess of Investments in Unconsolidated Real Estate Entities At times, certain of the Company’s investments in unconsolidated entities share of cumulative allocated losses and cash distributions received exceeds its cumulative allocated share of income and equity contributions. Although the Company typically does not make any guarantees of its investments in unconsolidated real estate entities other than certain customary non-recourse carve-out provisions, due to potential penalties along with potential upside financial returns, the Company generally intends to make any required capital contributions to maintain its ownership percentage and as such will record its share of cumulative allocated losses and cash distributions below zero. As a result, the carrying value of certain investments in unconsolidated entities is negative. Unconsolidated entities with negative carrying values are included in cash distributions and losses in excess of investments in unconsolidated entities in the Company’s consolidated balance sheets.
Revenue Recognition	Revenue Recognition Revenue from hotel operations is recognized when rooms are occupied and when services are provided. Revenue consists of amounts derived from hotel operations, including sales from room, meeting room, gift shop, in-room movie and other ancillary amenities. Sales, use, occupancy, and similar taxes are collected and presented on a net basis (excluded from revenue) in the accompanying consolidated statements of operations.
Share-Based Compensation	Share-Based Compensation The Company measures compensation expense for the restricted share awards based upon the fair market value of its common shares at the date of grant. The Company measures compensation expense for the LTIP and Class A Performance units based upon the Monte Carlo approach using volatility, dividend yield and a risk free interest rate in the valuation. Compensation expense is recognized on a straight-line basis over the vesting period and is included in general and administrative expense in the accompanying consolidated statements of operations. The Company pays dividends on vested and non-vested restricted shares, except for performance-based shares, for which dividends on unvested shares are not paid until those shares are vested. The Company has also issued Class A Performance LTIP units from time to time as part of its compensation practices. Prior to vesting, holders of Class A Performance LTIP Units will not be entitled to vote their Class A Performance LTIP units. In addition, under the terms of the Class A Performance LTIP units, a holder of a Class A Performance LTIP unit will generally (i) be entitled to receive 10% of the distributions made on a common unit of the Operating Partnership during the period prior to vesting of such Class A Performance LTIP unit (the “Pre-Vesting Distributions”), (ii) be entitled, upon the vesting of such Class A Performance LTIP unit, to receive a special one-time “catch-up” distribution equal to the aggregate amount of distributions that were paid on a common unit during the period prior to vesting of such Class A Performance LTIP unit minus the aggregate amount of Pre-Vesting Distributions paid on such Class A Performance LTIP unit, and (iii) be entitled, following the vesting of such Class A Performance LTIP unit, to receive the same amount of distributions paid on a common unit of the Operating Partnership.
Earnings Per Share	Earnings Per Share A two class method is used to determine earnings per share. Basic earnings per share ("EPS") is computed by dividing net income (loss) available for common shareholders, adjusted for dividends on unvested share grants, by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income (loss) available for common shareholders, adjusted for dividends or distributions, on unvested share grants and LTIP units, by the weighted average number of common shares outstanding plus potentially dilutive securities such as share grants or shares issuable in the event of conversion of common units. No adjustment is made for shares that are anti-dilutive during the period. The Company’s restricted share awards and LTIP units that are subject solely to time-based vesting conditions are entitled to receive dividends or distributions on the Company's common shares or the Operating Partnership's common units, respectively, if declared. In addition, dividends on the Class A Performance LTIP units are paid the equivalent of 10% of the declared dividends on the Company's common shares. The rights to these dividends or distributions declared are non-forfeitable. As a result, the unvested restricted shares and LTIP units that are subject solely to time-based vesting conditions, as well as 10% of the unvested Class A Performance LTIP units, qualify as participating securities requiring the allocation of earnings under the two-class method to calculate EPS. The percentage of earnings allocated to these participating securities is based on the proportion of the weighted average of these outstanding participating securities to the sum of the basic weighted average common shares outstanding and the weighted average of these outstanding participating securities. Basic EPS is then computed by dividing income less earnings allocable to these participating securities by the basic weighted average number of shares outstanding. Diluted EPS is computed similar to basic EPS, except the weighted average number of shares outstanding is increased to include the effect of potentially dilutive securities.
Income Taxes	Income Taxes The Company elected to be taxed as a REIT for federal income tax purposes. In order to qualify as a REIT under the Internal Revenue Code of 1986, as amended, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its annual REIT taxable income to its shareholders (which is computed without regard to the dividends paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax to the extent the Company distributes its REIT taxable income to its shareholders. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax on its REIT taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost unless the IRS grants the Company relief under certain statutory provisions. The Company leases its wholly owned hotels to TRS Lessees, which are wholly owned by the Company’s taxable REIT subsidiary (a “TRS”) which, in turn is wholly owned by the Operating Partnership. Additionally, the Company indirectly (i) owns its interest in the hotels owned by the NewINK JV ( 47 hotels) and the Inland JV ( 48 hotels) and (ii) owned its interest in the Torrance JV, which was sold on December 30, 2015 , through the Operating Partnership. All of the NewINK JV hotels and Inland JV hotels are, and the Torrance JV hotel was, leased to TRS Lessees in which the Company indirectly owns, or owned, as applicable, noncontrolling interests through its TRS holding company. The TRS is subject to federal and state income taxes and the Company accounts for taxes, where applicable, in accordance with the provisions of FASB Accounting Standards Codification 740 using the asset and liability method which recognizes deferred tax assets and liabilities for future tax consequences arising from differences between financial statement carrying amounts and income tax bases. On December 22, 2017, the TCJA was enacted. The TCJA includes a number of changes to the existing U.S. tax code, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017. Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, as a result of the TCJA being signed into law, the net deferred tax assets before valuation allowance were reduced by $0.6 million with a corresponding net adjustment to current year tax expense for the remeasurement of the Company’s U.S. net deferred tax assets. Our federal income tax expense for periods beginning in 2018 will be based on the new rate. As of December 31, 2017 , the Company is no longer subject to U.S federal income tax examinations for years before 2014 and with few exceptions to state examinations before 2014. The Company evaluates whether a tax position of the Company is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company has reviewed its tax positions for open tax years and has concluded no provisions for income taxes is required in the Company's consolidated financial statements as of December 31, 2017 . Interest and penalties related to uncertain tax benefits, if any, in the future will be recognized as operating expense. During the first quarter of 2015, management was notified that the Company's TRS was going to be examined by the State of Florida Department of Revenue for the tax years ended December 31, 2009 through 2013. The examination was closed in 2016 and no adjustments were required.
Organizational and Offering Costs	Organizational and Offering Costs The Company expenses organizational costs as incurred. Offering costs, which include selling commissions, are recorded as a reduction in additional paid-in capital in shareholders’ equity as shares are sold. For offering costs incurred prior to potential share offerings, these costs are initially recorded in deferred costs on the balance sheet and then recorded as a reduction to additional paid-in capital as shares are sold through the subsequent share offering.
Segment Information	Segment Information Management evaluates the Company's hotels as a single industry segment because all of the hotels have similar economic characteristics and provide similar services to similar types of customers.
Recently Issued Accounting Standards	Recently Issued Accounting Standards On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09 ("ASU 2014-09"), Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard permits the use of either the retrospective or modified retrospective approach. In July 2015, the FASB voted to defer the effective date to January 1, 2018 with early adoption beginning January 1, 2017. We adopted the new accounting guidance on January 1, 2018 on a modified retrospective basis, which requires a cumulative effect adjustment. The Company has finalized its evaluation of each of its revenue streams under the new model and because of the short-term, day-to-day nature of the Company's hotel revenues, the pattern of revenue recognition is not expected to change and we did not recognize any cumulative effect adjustment. Furthermore, we do not expect the updated accounting guidance to materially impact the recognition of or the accounting for disposition of hotels, since we primarily dispose of hotels to third parties in exchange for cash with few contingencies. On February 25, 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases , which relates to the accounting for leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than 12 months. In addition, this standard requires both lessees and lessors to disclose certain key information about lease transactions. Leases with a term of 12 months or less will be accounted for similarly to existing guidance for operating leases today. The Company is the lessee on certain air/land rights arrangements and an office lease and expects to record right of use assets and lease liabilities for these leases under the new standard. This guidance is effective for the Company on January 1, 2019, however, early adoption is permitted. The standard requires a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures. On August 26, 2016, the FASB issued ASU 2016-15 ("ASU 2016-15"), Classification of Certain Cash Receipts and Cash Payments, which clarifies and provides specific guidance on eight cash flow classification issues with an objective to reduce the current diversity in practice. This standard will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years with earlier adoption permitted and is to be applied on a retrospective basis. The Company has certain cash payments and receipts related to debt extinguishment and distributions from equity method investments that will be affected by the new standard. The Company does not anticipate that the adoption of ASU 2016-15 will have a material impact to our consolidated financial statements. On November 17, 2016, the FASB issued ASU 2016-18 ("ASU 2016-18"), Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This standard will be effective for public companies for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and all other entities for fiscal years beginning after December 15, 2018 and is to be applied on a retrospective basis. This standard addresses presentation of restricted cash in the consolidated statements of cash flows only and will have no effect on our reported consolidated financial condition or results of operations. On January 5, 2017, the FASB issued ASU 2017-01 ("ASU 2017-01"), Definition of a Business, which will likely result in more acquisitions being accounted for as asset acquisitions across all industries, particularly real estate, pharmaceutical and oil and gas. Application of the changes would also affect the accounting for disposal transactions. The changes to the definition of a business will likely result in more of the Company's property acquisitions qualifying as asset acquisitions, which will permit capitalization of acquisition costs. This standard will be effective for public business entities with a calendar year end in 2018 and all other entities have an additional year to adopt. The Company has adopted this guidance as of 2017. The adoption did not have a material impact on our consolidated financial statements.

Unvested restricted shares and unvested LTIP units could potentially dilute basic earnings per share in the future were not included in the computation of diluted loss per share, for the periods where a loss has been recorded, because they would have been anti-dilutive for the periods presented.
