[1]	Income (loss) allocated to noncontrolling interest in HHLP has been excluded from the numerator and Common Units and Vested LTIP Units have been omitted from the denominator for the purpose of computing diluted earnings per share since including these amounts in the numerator and denominator would have no impact. In addition, potentially dilutive common shares, if any, have been excluded from the denominator if they are anti-dilutive to income (loss) applicable to common shareholders.
[2]	* Assets are depreciated over a 7 to 40 year life, upon which the latest income statement is computed.
[3]	Income allocated to noncontrolling interest in Hersha Hospitality Limited Partnership (the "Operating Partnership" or "HHLP") has been excluded from the numerator and the Class A common shares issuable upon any redemption of the Operating Partnership's common units of limited partnership interest ("Common Units") and the Operating Partnership's vested LTIP units ("Vested LTIP Units") have been omitted from the denominator for the purpose of computing diluted earnings per share because the effect of including these shares and units in the numerator and denominator would have no impact. In addition, potentially dilutive common shares, if any, have been excluded from the denominator if they are anti-dilutive to income applicable to common shareholders.

Organization And Summary Of Significant Accounting Policies [Abstract]
Organization And Summary Of Significant Accounting Policies	NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Hersha Hospitality Trust (“we” or the “Company”) was formed in May 1998 as a self-administered, Maryland real estate investment trust. We have elected to be taxed and expect to continue to elect to be taxed as a real estate investment trust, or REIT, for federal income tax purposes.  The Company owns a controlling general partnership interest in Hersha Hospitality Limited Partnership (“HHLP” or the “Partnership”), which owns a 99% limited partnership interest in various subsidiary partnerships. Hersha Hospitality, LLC (“HHLLC”), a Virginia limited liability company, owns a 1% general partnership interest in the subsidiary partnerships and the Partnership is the sole member of HHLLC.  The Partnership owns a taxable REIT subsidiary (“TRS”), 44 New England Management Company (“44 New England” or “TRS Lessee”), which leases certain of the Company’s hotels.  Hersha’s common shares of beneficial interest trade on the New York Stock Exchange (“the NYSE”) under the ticker symbol "HT", its 6.875% Series C Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRC”, its 6.500% Series D Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRD”, and it’s 6.500% Series E Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRE.”  As of December 31, 2017, the Company, through the Partnership and subsidiary partnerships, wholly owned 41 limited and full service hotels. All of the wholly owned hotel facilities are leased to the Company’s TRS, 44 New England.  In addition to the wholly owned hotel properties, as of December 31, 2017, the Company owned joint venture interests in another nine properties. The properties owned by the joint ventures are leased to a TRS owned by the joint venture or to an entity owned by the joint venture partners and 44 New England. The following table lists the properties owned by these joint ventures:     Joint Venture Property Location Lessee/Sublessee   Unconsolidated Joint Ventures  Cindat Hersha Owner JV, LLC (1) Hampton Inn Herald Square, NY Cindat Hersha Lessee JV, LLC  Hampton Inn Chelsea, NY Cindat Hersha Lessee JV, LLC  Hampton Inn Times Square, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Express Times Square, NY Cindat Hersha Lessee JV, LLC  Candlewood Suites Times Square, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Wall Street, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Express Water Street, NY Cindat Hersha Lessee JV, LLC  SB Partners, LLC (2) Holiday Inn Express South Boston, MA South Bay Sandeep, LLC  Hiren Boston, LLC (2) Courtyard South Boston, MA South Bay Boston, LLC  (1) Our common ownership interest in the CINDAT JV equals 30% at December 31, 2017. As of December 31, 2017, we owned a $43,194 preferred equity interest in the joint venture. See Note 3 – Investment in Unconsolidated Joint Ventures for a more detailed explanation of our ownership interest and the related distribution of earnings within the venture.  (2) Our common ownership interest in SB Partners, LLC and Hiren Boston, LLC equals 50% .  At December 31, 2016, Mystic Partners, LLC owned an interest in three hotel properties. Our interest in Mystic Partners, LLC is relative to our interest in each of the three properties owned by the joint venture as defined in the joint venture’s governing documents. Each of the three properties owned by Mystic Partners, LLC is leased to a separate entity that is consolidated in Mystic Partners Leaseco, LLC which is owned by 44 New England and our joint venture partner in Mystic Partners, LLC.  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  On January 3, 2017, we transferred to our joint venture partner all of our partnership interests in the Hartford Marriott and the Hartford Hilton for $8.5 million, which represents a 100% recovery of our equity investment in these assets. We also simultaneously assumed full ownership of the Mystic Marriott Hotel & Spa without any additional cash payment to the joint venture partner.  The properties are managed by eligible independent management companies, including Hersha Hospitality Management, LP (“HHMLP”). HHMLP is owned in part by certain of our trustees and executive officers and other unaffiliated third party investors.  Principles of Consolidation and Presentation  The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include all of our accounts as well as accounts of the Partnership, subsidiary partnerships and our wholly owned TRS Lessee. All significant inter-company amounts have been eliminated.  Consolidated properties are either wholly owned or owned less than 100% by the Partnership and are controlled by the Company as general partner of the Partnership. Properties owned in joint ventures are also consolidated if the determination is made that we are the primary beneficiary in a variable interest entity (VIE) or we maintain control of the asset through our voting interest in the entity. Control can be demonstrated when the general partner has the power to impact the economic performance of the partnership, which includes the ability of the general partner to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the limited partners and the inability of the limited partners to replace the general partner. Control can be demonstrated by the limited partners if the limited partners have the right to dissolve or liquidate the partnership or otherwise remove the general partner without cause or have rights to participate in the significant decisions made in the ordinary course of the partnership’s business. We evaluate each of our investments and contractual relationships to determine whether they meet the guidelines for consolidation. Entities are consolidated if the determination is made that we are the primary beneficiary in a VIE or we maintain control of the asset through our voting interest or other rights in the operation of the entity. To determine if we are the primary beneficiary of a VIE, we evaluate whether we have a controlling financial interest in that VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE. Control can also be demonstrated by the ability of a member to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the other member and the inability of the members to replace the managing member. Based on our examination, the following entities were determined to be VIE’s: HHLP; Cindat Hersha Lessee JV, LLC; South Bay Boston, LLC; Hersha Statutory Trust I; and Hersha Statutory Trust II. As noted, HHLP meets the criteria as a VIE. The Company’s most significant asset is its investment in HHLP, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of HHLP. Cindat Hersha Lessee JV, LLC is a VIE that leases hotel property. The entity is consolidated by the lessors, the primary beneficiary. Our maximum exposure to losses due to our investment in Cindat Hersha Owner JV, LLC is limited to our investment in the joint venture which is $0 as of December 31, 2017. Also, South Bay Boston, LLC lease s hotel property is a VIE. The entity is consolidated by the lessors, the primary beneficiary. Hersha Statutory Trust I and Hersha Statutory Trust II are VIEs but HHLP is not the primary beneficiary in these entities. Accordingly, the accounts of Hersha Statutory Trust I and Hersha Statutory Trust II are not consolidated. On September 2, 2016, we exercised our option to acquire the non-controlling equity interests in Brisam Management DE, LLC (“Brisam”), the entity which owns the real estate assets of the Holiday Inn Express, New York, NY. We paid approximately $2,318 to exercise this option. Prior to the exercise of this option, we had consolidated Brisam, a variable interest entity, in our financial statements as we determined we were the primary beneficiary.  We allocate resources and assess operating performance based on individual hotels and consider each one of our hotels to be an operating segment. No operating segment, individually, meets the threshold for a reportable segment as defined within ASC Topic 280 – Segment Reporting, nor do they fully satisfy the requisite aggregation criteria therein. As a result, the Company does not present separate operating segment information within the Notes to the Consolidated Financial Statements.  Use of Estimates  The preparation of financial statements in conformity with accounting principles generally accepted in the United States (US GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.  Although we believe the assumptions and estimates we made are reasonable and appropriate, as discussed in the applicable sections throughout these Consolidated Financial Statements, different assumptions and estimates could materially impact our reported results.  Investment in Hotel Properties  The Company records the value of hotel properties acquired based on the fair value of the acquired real estate, furniture, fixtures and equipment, and intangible assets and the fair value of liabilities assumed, including debt. The fair value allocations were determined using Level 3 inputs, which are typically unobservable and are based on our own assumptions, as there is little, if any, related market activity. The Company’s investments in hotel properties are carried at cost and are depreciated using the straight-line method over the following estimated useful lives:  Building and Improvements 7 to 40 Years Furniture, Fixtures and Equipment 2 to 7 Years The Company periodically reviews the carrying value of each hotel to determine if circumstances indicate impairment to the carrying value of the investment in the hotel or that depreciation periods should be modified. If facts or circumstances indicate the possibility of impairment, the Company will prepare an estimate of the undiscounted future cash flows, without interest charges, of the specific hotel. Based on the property’s undiscounted future cash flows, the Company will determine if the investment in such hotel is recoverable. If impairment is indicated, an adjustment will be made to reduce the carrying value of the hotel to reflect its fair value.  We consider a hotel to be held for sale when management and our independent trustees commit to a plan to sell the property, the property is available for sale, management engages in an active program to locate a buyer for the property and it is probable the sale will be completed within a year of the initiation of the plan to sell.  Acquisition-related cost, such as due diligence, legal and accounting fees, are not capitalized or applied in determining the fair value of the above acquired assets.  Investment in Unconsolidated Joint Ventures  If it is determined that we do not have a controlling interest in a joint venture, either through our financial interest in a VIE or our voting interest in a voting interest entity, the equity method of accounting is used. Under this method, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, limited to the extent of our investment in, advances to and commitments for the investee. Pursuant to our joint venture agreements, allocations of profits and losses of some of our investments in unconsolidated joint ventures may be allocated disproportionately as compared to nominal ownership percentages due to specified preferred return rate thresholds. See Note 3 – Investment in Unconsolidated Joint Ventures for a more detailed explanation of the methodology used in determining the allocation of profits and losses within our joint ventures.  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, we will estimate the fair value of the investment. Our estimate of fair value takes into consideration factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and 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 the impairment is considered other than temporary, the loss will be measured as the excess of the carrying amount over the fair value of our investment in the unconsolidated joint venture.  Cash and Cash Equivalents  Cash and cash equivalents represent cash on hand and in banks plus short-term investments with an initial maturity of three months or less when purchased. NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  Escrow Deposits  Escrow deposits include reserves for debt service, real estate taxes, and insurance and reserves for furniture, fixtures, and equipment replacements, as required by certain mortgage debt agreement restrictions and provisions.  Hotel Accounts Receivable  Hotel accounts receivable consists primarily of meeting and banquet room rental and hotel guest receivables. The Company generally does not require collateral. Ongoing credit evaluations are performed and an allowance for potential losses from uncollectible accounts is provided against the portion of accounts receivable that is estimated to be uncollectible.  Deferred Financing Costs  Deferred financing costs are recorded at cost and amortized over the terms of the related indebtedness using the effective interest method.  Due from/to Related Parties  Due from/to Related Parties represents current receivables and payables resulting from transactions related to hotel management and project management with affiliated entities. Due from related parties results primarily from advances of shared costs incurred. Due to affiliates results primarily from hotel management and project management fees incurred. Both due to and due from related parties are generally settled within a period not to exceed one year.  Intangible Assets and Liabilities  Intangible assets consist of leasehold intangibles for above-market value of in-place leases and deferred franchise fees. The leasehold intangibles are amortized over the remaining lease term. Deferred franchise fees are amortized using the straight-line method over the life of the franchise agreement.  Intangible liabilities consist of leasehold intangibles for below-market value of in-place leases. The leasehold intangibles are amortized over the remaining lease term. Intangible liabilities are included in the accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets.  Development Project Capitalization  We have opportunistically engaged in the development and re-development of hotel assets. We capitalize expenditures related to hotel development projects and renovations, including indirect costs such as interest expense, real estate taxes and utilities related to hotel development projects and renovations.  Noncontrolling Interest  Noncontrolling interest in the Partnership represents the limited partner’s proportionate share of the equity of the Partnership. Income (loss) is allocated to noncontrolling interest in accordance with the weighted average percentage ownership of the Partnership during the period. At the end of each reporting period the appropriate adjustments to the income (loss) are made based upon the weighted average percentage ownership of the Partnership during the period. Our ownership interest in the Partnership as of December 31, 2017, 2016 and 2015 was 92.5% , 93.6% , and 95.0% , respectively.  We define a noncontrolling interest as the portion of equity in a subsidiary not attributable, directly or indirectly, to a parent.  Such noncontrolling interests are reported on the consolidated balance sheets within equity, but separately from the shareholders’ equity. Revenues, expenses and net income or loss attributable to both the Company and noncontrolling interests are reported on the consolidated statements of operations. NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  In accordance with US GAAP, we classify securities that are redeemable for cash or other assets at the option of the holder, or not solely within the control of the issuer, outside of permanent equity in the consolidated balance sheet. The Company makes this determination based on terms in applicable agreements, specifically in relation to redemption provisions. Additionally, with respect to noncontrolling interests for which the Company has a choice to settle the contract by delivery of its own shares, the Company considers the guidance in US GAAP to evaluate whether the Company controls the actions or events necessary to issue the maximum number of common shares that could be required to be delivered at the time of settlement of the contract.  We classify the noncontrolling interests of our consolidated variable interest entity, and certain Common Units (“Nonredeemable Common Units”) as equity. The noncontrolling interests of Nonredeemable Common Units totaled $54,286 as of December 31, 2017 and $44,321 as of December 31, 2016. As of December 31, 2017, there were 3,223,366 Nonredeemable Common Units outstanding with a fair market value of $56,087 , based on the price per share of our common shares on the NYSE on such date.  In accordance with the partnership agreement of the Partnership, holders of these units may redeem them for cash unless we, in our sole and absolute discretion, elect to issue common shares on a one-for-one basis in lieu of paying cash.  Net income or loss attributed to Nonredeemable Common Units and Redeemable Common Units (collectively, “Common Units”), as well as the net income or loss related to the noncontrolling interests of our consolidated variable interest entity, is included in net income or loss in the consolidated statements of operations. Net income or loss attributed to the Common Units and the noncontrolling interests of our consolidated joint ventures and consolidated variable interest entity is excluded from net income or loss applicable to common shareholders in the consolidated statements of operations.  Shareholders’ Equity  On May 31, 2016, we completed a public offering of 7,700,000 (including 700,000 overallotment shares sold on June 14, 2016) 6.50% Series D Cumulative Redeemable Preferred Shares. These shares have a par value of $0.01 per share with a $25.00 liquidation preference per share. Net proceeds of the offering, after deducting the underwriting discount and the offering expenses payable by us, were approximately $185,999 . We utilized the net proceeds of the offering to redeem all outstanding 8.00% Series B Cumulative Redeemable Preferred Shares on June 8, 2016, and for general corporate purposes.  Shares of our 8.00% Series B Cumulative Redeemable Preferred Shares were redeemed at a per share redemption price of $25.00 together with accrued and unpaid dividends to the redemption date for an aggregate per share redemption price of $25.3722 . Dividends ceased accruing on the Series B Preferred Shares on June 8, 2016.  On November 7, 2016, we completed a public offering of 4,000,000 6.50% Series E Cumulative Redeemable Preferred Shares. These shares have a par value of $0.01 per share with a $25.00 liquidation preference per share. Net proceeds of the offering, after deducting the underwriting discount and the offering expenses payable by us, were approximately $96,585 . We utilized the net proceeds of the offering for general corporate purposes.  Terms of the Series C, Series D and Series E Preferred Shares outstanding at December 31, 2017 and 2016 are summarized as follows:     Dividend Per Share  Shares Outstanding Year Ended December 31,  Series December 31, 2017 December 31, 2016 Aggregate Liquidation Preference Distribution Rate 2017 2016  Series C 3,000,000 3,000,000 $ 75,000 6.875% $ 1.7188 $ 1.7188  Series D 7,701,700 7,700,000 $ 192,500 6.500% $ 1.6250 1.0157  Series E 4,000,000 4,000,000 $ 100,000 6.500% $ 1.6250 0.3069  Total 14,701,700 14,700,000  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  On December 23, 2014, we amended our partnership agreement to allow for the issuance of profits interests in HHLP in the form of LTIP Units, a new class of limited partnership units in HHLP, and to establish the terms of the LTIP Units. The LTIP Units vest on December 31 and June 1 of each year, beginning on December 31, 2014 and ending on June 1, 2017. The LTIP Units contain restricted stock awards that were forfeited and replaced with LTIP Unit awards with similar terms. The total number of Restricted Stock Awards forfeited and LTIP Units awarded was 1,948,324 .  In October 2016, our Board of Trustees authorized a new share repurchase from time to time up to an aggregate of $100,000 of our outstanding shares. For the year ended December 31, 2017, the Company repurchased 1,991,573 common shares for an aggregate purchase price of $35,178 under the October 2016 repurchase programs. Upon repurchase by the Company, these common shares ceased to be outstanding and became authorized but unissued common shares.  In April 2017, we entered into Equity Distribution Agreements with four investment banks whereby we agreed to sell up to 8,000,000 Class A common shares, up to 1,000,000 Series D Cumulative Redeemable Preferred Shares, and up to 1,000,000 Series E Cumulative Redeemable Preferred Shares from time to time in an “at the market” offering. In conjunction with this transaction, the Company increased the number of authorized Class A common shares from 90,000,000 to 104,000,000 . For the year ended December 31, 2017, we issued 1,700 Series D Preferred Shares through this program.  In December 2017, our Board of Trustees authorized a new share repurchase program for up to $100,000 of common shares which commenced on January 1, 2018. We expect to complete the new repurchase program prior to December 31, 2018, unless extended by our Board of Trustees.  Stock Based Compensation  We measure the cost of employee service received in exchange for an award of equity instruments based on the grant-date fair value of the award. The compensation cost is amortized on a straight line basis over the period during which an employee is required to provide service in exchange for the award. The compensation cost related to performance awards that are contingent upon market-based criteria being met is recorded at the fair value of the award on the date of the grant and amortized over the performance period.  Derivatives and Hedging  The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and interest rate caps as part of its cash flow hedging strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. Interest rate caps designated as cash flow hedges limit the Company’s exposure to increased cash payments due to increases in variable interest rates.  Revenue Recognition We recognize revenue and expense for all consolidated hotels as hotel operating revenue and hotel operating expense when earned and incurred. These revenues are recorded net of any sales or occupancy taxes collected from our guests. We participate in frequent guest programs sponsored by the brand owners of our hotels and we expense the charges associated with those programs, as incurred.  Other revenues consist primarily of fees earned for asset management services provided to hotels we own through unconsolidated joint ventures. Fees are earned as a percentage of hotel revenue and are recorded in the period earned to the extent of the noncontrolling interest ownership.  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  Income Taxes  The Company has elected to be taxed as a REIT under applicable provisions of the Internal Revenue Code of 1986, as amended, or the Code, and intends to continue to qualify as a REIT. In general, under such provisions, a trust which has made the required election and, in the taxable year, meets certain requirements and distributes to its shareholders at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains, will not be subject to federal income tax to the extent of the income which it distributes. Earnings and profits, which determine the taxability of dividends to shareholders, differ from net income reported for financial reporting purposes due primarily to differences in depreciation of hotel properties for federal income tax purposes.  Deferred income taxes relate primarily to the TRS Lessee and are accounted for using the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial reporting bases of assets and liabilities of the TRS Lessee and their respective tax bases and for their operating loss and tax credit carry forwards based on enacted tax rates expected to be in effect when such amounts are realized or settled. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based on consideration of available evidence, including tax planning strategies and other factors.  The Company may recognize a tax benefit from an uncertain tax position when it is more-likely-than-not (defined as a likelihood of more than 50%) that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. If a tax position does not meet the more-likely-than-not recognition threshold, despite the Company’s belief that its filing position is supportable, the benefit of that tax position is not recognized in the statements of operations. The Company recognizes interest and penalties, as applicable, related to unrecognized tax benefits as a component of income tax expense. The Company recognizes unrecognized tax benefits in the period that the uncertainty is eliminated by either affirmative agreement of the uncertain tax position by the applicable taxing authority, or by expiration of the applicable statute of limitation. For the years ended December 31, 2017, 2016 and 2015, the Company did no t record any uncertain tax positions. As of December 31, 2017, with few exceptions, the Company is subject to tax examinations by federal, state, and local income tax authorities for years 2003 through 2017. Reclassification  Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation.  New Accounting Pronouncements  In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The update will make more financial and nonfinancial hedging strategies eligible for hedge accounting, changes how companies assess hedge effectiveness, and amends the presentation and disclosure requirements for hedging transactions. The provisions of the update will be effective for the Company starting January 1, 2019 with the early adoption available. Based on the type of derivative instruments within the Company’s portfolio, we do not anticipate this update to have a material effect on our consolidated financial statements and related disclosures, however, we are currently assessing the ultimate impact of this update.  In February 2017, the FASB issued ASU No. 2017-05, Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) . The update defines the term “in substance nonfinancial asset” as it is presented in Subtopic 610-20 as a “financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets that are promised to the counterparty in the contract is concentrated in nonfinancial assets.” As it relates to the Company, real estate, such as land and building, would be considered an example of a nonfinancial asset. Additionally, the update provides guidance over partial sale transactions, particularly, when an entity should derecognize a distinct nonfinancial asset or in substance nonfinancial asset in a partial sale transaction, and the extent of gain that should be recognized as a result of the partial sale transaction. This standard is effective in conjunction with ASU No. 2014-09 (presented below), which is effective for periods beginning after December 15, 2017 and the Company will adopt effective January 1, 2018, the same time as the adoption of ASU No. 2014-09. The Company has considered how the provisions of this update affect our adoption of ASU No. 2014-09. See below for our discussion of ASU No. 2014-09 and the effect it will have on our consolidated financial statements and related disclosures. NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business , which clarifies the definition of a business as it relates to acquisitions and business combinations. The update adds further guidance that assists preparers in evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. We expect most of our hotel property acquisitions to qualify as asset acquisitions under the standard which requires the capitalization of acquisition costs to the underlying assets. The Company expects the standard to have an impact on our financial statements in periods during which we complete significant hotel acquisitions. For instance, during the year ended December 31, 2017, the Company incurred $2,203 in expenses related to acquisition costs that would have been subject to capitalization under this ASU. This standard is effective for periods beginning after December 31, 2017, and the Company will adopt it effective January 1, 2018.  Effective January 1, 2017, we adopted ASU No. 2016-09, Improvements to Employee Share-Based Award Payment Accounting , which simplifies various aspects of how share-based payments are accounted for and presented in the financial statements. This standard requires companies to record all of the tax effects related to share-based payments through the income statement, allows companies to elect an accounting policy to either estimate the share based award forfeitures (and expense) or account for forfeitures (and expense) as they occur, and allows companies to withhold a percentage of the shares issuable upon settlement of an award up to the maximum individual statutory tax rate without causing the award to be classified as a liability. The Company has elected to expense forfeitures of share-based award as they occur as our accounting policy. The adoption of ASU No. 2016-09 had no material impact on our consolidated financial statements and related disclosures.  In November 2016 the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) , which provides guidance on the presentation of restricted cash or restricted cash equ

Acquisition-related cost s , such as due diligence, legal and accounting fees, are not capitalized or applied in determining the fair value of the above acquired assets. During the year ended December 31, 201 7 , we incurred $2,203 in acquisition costs related to acquired assets and costs related to terminated transactions . NOTE 2 – INVESTMENT IN HOTEL PROPERTIES (CONTINUED)  Included in the consolidated statements of operations for the year ended December 31, 2017 are total revenues of $62,147 and a total net income of $3,042 for hotels we have acquired and consolidated since the date of acquisition. These amounts represent the results of operations for these hotels since the date of acquisition as presented in the table below:      Year Ended December 31, 2017  Hotel Revenue Net Income (Loss)  Mystic Marriott Hotel & Spa, Groton, CT $ 21,247 $ 1,700  The Ritz-Carlton, Coconut Grove, FL 13,390 (693)  The Pan Pacific Hotel, Seattle, WA 13,128 493  Philadelphia Westin, Philadelphia, PA 14,382 1,542   Total $ 62,147 $ 3,042  Lease Buyout  During November 2016, we signed an agreement with our restaurant lessee at the Courtyard Cadillac Miami to buyout the remainder of their current lease. The agreement was made in conjunction with our overall property improvement plan, which will also include room and common area upgrades, with the intention to rebrand the hotel to a more upscale Marriott brand. As defined by terms of the agreement, we were contractually obligated to pay total consideration to complete the buyout of $10,000 and issue 450,000 operating partnership units. During the fourth quarter of 2016, we paid $5,000 and issued 225,000 units valued at $4,400 with the remainder of the consideration due upon completion of the buyout. During 2016, we accounted for this transaction in accordance with ASU 420 “Exit or Disposal Cost Obligations,” recording the entire amount of consideration as an expense at the time of agreement execution, resulting in a total expense of $18,831 . This recorded expense was partially offset by the write-off of an intangible liability related to the lease of $2,000 during the fourth quarter of 2016. In September 2017, we completed the buy-out through the payment of $5,000 and the issuance of 225,000 units valued at $4,133 .  Impairment of Investment in Hotel Property  During the year ended December 31, 2017, the Company identified one hotel property whereby the carrying value of our investment in hotel property exceeded its fair value and based on the facts and circumstances, management determined the excess carrying value to be unrecoverable. Accordingly, the Company recorded a $4,082 impairment charge for the year ended December 31, 2017. The fair value of this property was determined using Level 3 inputs, which are typically unobservable and are based on our own assumptions. No impairment charges were recorded during the years ended December 31, 2016 and 2015.  Property Damage from Natural Disaster  During September 2017, all six of our hotels located in South Florida incurred property damage and an interruption of business operations as a result of Hurricane Irma. Two of our hotels, the Courtyard Cadillac Miami and the Parrot Key Hotel & Resort, incurred significant physical damage and have been closed since the disaster with the expectation to open for business during the first quarter of 2018. The remaining four properties have resumed normal business activities as of December 3 1 , 2017. Based on our initial assessments, we have recorded estimated property impairment and remediation losses of $14,291 during the year ended December 31 , 2017 offset by a corresponding insurance claim receivable of $10,023 for a net loss in excess of estimated insurance recoveries of $4,268 . Our current insurance policies also contain coverage for income lost due to business interruption from covered losses. Any recoveries obtained through business interruption coverage will be recorded at such time that the recovery is probable. The Company recorded $0 related to business interruption insurance coverage during the year ended December 31 , 2017.

This hotel was acquired by the Company in April 2006.

This hotel was acquired by the Company in August 2010. The operating results for this hotel are included in operating income until the date of sale as shown in the consolidated statements of operations for the years ended December 31, 2016 and 2015 as disposition of this hotel does not represent a strategic shift in our business.  On February 4, 2016, we announced the signing of asset purchase and contribution agreements (the “Contribution Agreements”) with Cindat Manhattan Hotel Portfolio (US) LLC (“Cindat”) to form a joint venture, Cindat Hersha Owner JV, LLC (the “Owner JV”), which initially invested in seven of our limited service hotels in Manhattan (the “JV Properties”). This transaction was consummated on April 29, 2016. The Contribution Agreements valued the JV Properties at $543,500 . Cindat contributed $354,550 and received a 70% senior common equity interest in Owner JV. We contributed the JV Properties to Owner JV and received $354,550 in cash and a preferred equity interest initially valued at $37,000 . In addition, we retained a 30% junior common equity interest in Owner JV. We contributed $12,239 and Cindat contributed an aggregate of $14,105 in working capital and closing costs for the formation of Owner JV, and finance costs related to debt originated on the JV Properties by Owner JV. In addition, we incurred additional closing costs associated with the contribution of the JV Properties to Owner JV of $10,653 .  Prior to the contribution to Owner JV, our basis in the JV Properties was $264,658 . Our preferred equity and junior common equity interest in Owner JV was initially recorded at $104,248 which represents our retained interest in the JV Properties at our basis prior to contribution and additional contributions made for the formation of Owner JV. Please refer to “Note 3 –Investment in Unconsolidated Joint Ventures” more information about the joint venture with Cindat.  Due to our continuing interest in the JV Properties, gain recognized on the properties is limited to cash received less the basis of the properties contributed. As a result, we recognized a gain on the disposition of hotel properties of $89,892 and recorded a deferred gain, which is recorded as a liability in the consolidated balance sheets. The deferred gain will be recognized as income in a future period if an event occurs that changes our retained interest in the JV Properties.  Assets Held For Sale  In September 2017, we entered into a purchase and sale agreement to sell the Hyatt House, Gaithersburg, MD to an unaffiliated buyer for a sales price of $19,000 .

Investment In Unconsolidated Joint Ventures [Abstract]
Investment In Unconsolidated Joint Ventures	NOTE 3 – INVESTMENT IN UNCONSOLIDATED JOINT VENTURES  As of December 31, 201 7 and December 31, 201 6 our investment in unconsolidated joint ventures consisted of the following:      Percent Preferred  Joint Venture Hotel Properties Owned Return December 31, 2017 December 31, 2016   SB Partners, LLC Holiday Inn Express, South Boston, MA 50.0% N/A $ 1,407 $ 913  Hiren Boston, LLC Courtyard by Marriott, South Boston, MA 50.0% N/A 2,162 2,112  Cindat Hersha Owner JV, LLC Hilton and IHG branded hotels in NYC 30.0% * - 3,717  Mystic Partners, LLC Hilton and Marriott branded hotels in CT 8.8% -66.7% 8.5% non-cumulative - 4,699  $ 3,569 $ 11,441 *See explanation below of the Cindat Hersha Owner JV, LLC (“Owner JV”) for more information on the preferred return provisions of this joint venture.  On February 7, 2018, the Cindat Hersha JV refinanced its existing debt with the p roceeds being used to repay the venture’s existing debt, which consisted of $285,000 of mortgage debt and $50,000 of mezzanine debt, and to redeem our $43 ,194 preferred equity interest in the venture. The amount of the cash distribution available to redeem our outstanding accrued return has not been completed as of the date of this filing.  On January 3, 2017, we redeemed our joint venture interest in Mystic Partners, LLC by acquiring a 100% ownership interest in the Mystic Marriott Hotel & Spa and transferring our minority ownership interests in the Hartford Marriott and Hartford Hilton to our joint venture partner. We received $11,623 in cash and assumed a mortgage on the Mystic Marriott Hotel & Spa of $41,333 as consideration for this redemption and transfer of our minority interest. Subsequent to the assumption of the mortgage, the Company fully paid off the outstanding balance of the debt and added the property to the borrowing base of our Credit Facility. As a result of the remeasurement of the consideration received to fair value, the Company recognized a gain of $16,2 40 in conjunction with this transaction.  Income/Loss Allocation  For the Cindat Hersha Owner JV, LLC cash available for distribution will be distributed (1) to us until we receive a 9% annual rate of return on our contributed $43,194 preferred equity interest, (2) then to Cindat until they receive a return on their contributed $142,000 senior common equity interest, currently at 9.5% , and (3) then to us until we receive an 8% return on our contributed $60,857 junior common equity interest. Any cash available for distribution remaining will be split 30% to us and 70% to Cindat. Cindat’s senior common equity return is reduced by 0.5% annually for 4 years following the closing until it is set at a rate of 8% for the remainder of the life of the joint venture. Beginning June 30, 2016, a lender to the Owner JV determined that certain debt coverage ratio covenants contained in its loan agreement were not met. Pursuant to these agreements, the lender elected to escrow the operating cash flow for Owner JV, which continues as of December 31, 2017. The failure to meet these covenants, however, does not constitute an event of default. As of December 31, 2017, based on the income allocation methodology described above, the Company has absorbed cumulative losses equal to our accounting basis in the joint venture resulting in a $0 investment balance in the table above, however, we currently maintain a positive equity balance within the venture. This difference is due to difference in our basis inside the venture versus our basis outside of the venture, which is explained later in this note.  For SB Partners, LLC and Hiren Boston, LLC, income or loss is allocated to us and our joint venture partners consistent with the allocation of cash distributions in accordance with the joint venture agreements. This results in an income allocation consistent with our percentage of ownership interests.  Any difference between the carrying amount of any of our investments noted above and the underlying equity in net assets is amortized over the expected useful lives of the properties and other intangible assets.   NOTE 3 – INVESTMENT IN UNCONSOLIDATED JOINT VENTURES (CONTINUED)  Income recognized during the years ended December 3 1 , 201 7, 2016 and 201 5 , for our investments in unconsolidated joint ventures is as follows:      Year Ended December 31,  2017 2016 2015  SB Partners, LLC $ 494 $ 618 $ 582  Hiren Boston, LLC 750 839 694  Cindat Hersha Owner JV, LLC (3,717) (137) (311)  Mystic Partners, LLC - (3,143) -  (Loss) Income from Unconsolidated Joint Venture Investments $ (2,473) $ (1,823) $ 965  The following tables set forth the total assets, liabilities, equity and components of net income or loss, including the Company’s share, related to the unconsolidated joint ventures disc ussed above as of December 31 , 201 7 and December 31 , 2016 and for the years ended December 31, 2017, 2016 and 2015 .

Deposits with Unaffiliated Third Parties - These deposits represent deposits made by the Company with unaffiliated third parties for items such as lease security deposits, utility deposits, and deposits with unaffiliated third party management companies.  Deferred Tax Asset - We have approximately $10,934 of net deferred tax assets as of December 31, 201 7 . The Tax Cuts and Jobs Act was enacted on December 22, 2017 and instituted significant changes to the federal income tax law. Effective January 1, 2018, the statutory rate applicable to the Company decreased from 34% to 21% . As a result of the decrease in statutory rate, our deferred tax assets and liabilities that will apply to future periods were remeasured as of December 31, 2017. We recognized a decrease of $4,601 to our net deferred tax asset to reflect this change in the tax rate. We have considered various factors, including future reversals of existing taxable temporary differences, future projected taxable income and tax planning strategies in determining a valuation allowance for our deferred tax assets, and we believe that it is more likely than not that we will be able to realize the $10,934 o f net deferred tax assets in the future.  Property Insurance Receivable – This category represents the amount of building impairment & remediation costs as a result of Hurricane Irma that we expect to receive from our insurance companies.

Debt [Abstract]
Debt	NOTE 5 – DEBT  Mortgages  Mortgages payable at December 31, 2017 and December 31, 2016 consisted of the following:     December 31, 2017 December 31, 2016  Mortgage Indebtedness $ 308,508 $ 338,529  Net Unamortized Premium 1,802 2,313  Net Unamortized Deferred Financing Costs (2,627) (3,021)  Mortgages Payable $ 307,683 $ 337,821   Liabilities Related to Hotel Assets Held for Sale $ - $ 51,428  Net Unamortized Deferred Financing Costs associated with entering into mortgage indebtedness are deferred and amortized over the life of the mortgages. Net Unamortized Premiums are also amortized over the remaining life of the loans.  Mortgage indebtedness balances are subject to fixed and variable interest rates, which ranged from 3.56% to 6.30% as of December 31, 2017. Aggregate interest expense incurred under the mortgage loans payable totaled $12,405, and $20,916 and $26,581 during the years ended December 31, 2017, 2016, and 2015 respectively.  Our mortgage indebtedness contains various financial and non-financial covenants customarily found in secured, non-recourse financing arrangements. Our mortgage loans payable typically require that specified debt service coverage ratios be maintained with respect to the financed properties before we can exercise certain rights under the loan agreements relating to such properties. If the specified criteria are not satisfied, the lender may be able to escrow cash flow generated by the property securing the applicable mortgage loan. We have determined that all debt covenants contained in the loan agreements securing our hotel properties were met as of December 31, 2017.  As of December 31, 2017, the maturity dates for the outstanding mortgage loans ranged from January 2018 to September 2025 .  Subordinated Notes Payable  We have two junior subordinated notes payable in the aggregate amount of $51,548 to the Hersha Statutory Trusts pursuant to indenture agreements which will mature on July 30, 2035 , but may be redeemed at our option, in whole or in part, prior to maturity in accordance with the provisions of the indenture agreements. The $25,774 notes issued to Hersha Statutory Trust I and Hersha Statutory Trust II, bear interest at a variable rate of LIBOR plus 3% per annum. This rate resets two business days prior to each quarterly payment. The face value of the notes payable is offset by $917 and $970 as of December 31, 2017 and 2016, respectively, in net deferred financing costs incurred as a result of entering into these indentures. The deferred financing costs are amortized over the life of the notes payable. The weighted average interest rate on our two junior subordinated notes payable during the years ended December 31, 201 6 , 201 5 and 201 4 was 4.24% , 3.75% and 3.33% , respectively. Also included in the balance of notes payable at December 31, 2017 is $3,150 in seller financing provided in connection with the purchase of the Ritz-Carlton Coconut Grove, which bears interest at a fixed rate of 6% per annum, and matures on February 1, 2018 . Interest expense incurred on notes payable totaled $2,358 , $1,931 and $1,715 for the years ended December 31, 201 6 , 201 5 and 201 4 , respectively.  NOTE 5 – DEBT (CONTINUED)  Credit Facilities  We maintain three unsecured credit agreements which aggregate to $975,000 with Citigroup Global Markets Inc., Wells Fargo Bank, Inc. and various other lenders. The first credit agreement was amended and restated during the third quarter of 2017. The first credit facility now provides for a $475,000 senior unsecured credit facility (“Credit Facility”) which was an increase over the existing credit facility capacity of $460,520 . The Credit Facility consists of a $250,000 senior unsecured revolving line of credit (“Line of Credit”), for which the available balance remained unchanged as a result of the refinance, and a senior unsecured term loan (“First Term Loan”) for which the balance increased to $225,000 from $210,520 during the refinance. The Credit Facility expires on August 10, 2022 , and, provided no event of default has occurred, we may request that the lenders renew the credit facility for an additional one - year period. The Credit Facility is also expandable to $875,000 at our request, subject to the satisfaction of certain conditions.  Our second credit agreement provides for a $300,000 senior unsecured term loan agreement (“Second Term Loan”) and expires on August 10, 2020 .  Our third credit agreement provides for a $200,000 senior unsecured term loan agreement (“Third Term Loan”) and expires on August 2, 2021 .  As of December 31, 2017 and 2016, the Company had an outstanding balance on the term loans of $718,900 and $666,620 , respectively. As of December 31, 2017 and 2016, the Company had an outstanding balance on the line of credit of $16,100 and $0.  The amount that we can borrow at any given time under our Line of Credit, and the First, Second and Third Term Loan (each a “Term Loan” and together the “Term Loans”) is governed by certain operating metrics of designated unencumbered hotel properties known as borrowing base assets. As of December 31, 201 7 , the following hotel properties were borrowing base assets:    - Courtyard, Brookline, MA - Hampton Inn, Washington, DC  - Holiday Inn Express, Cambridge, MA - Ritz Carlton, Washington, DC  - Envoy Hotel, Boston, MA - Hilton Garden Inn, M Street, Washington, DC  - The Boxer, Boston, MA - Residence Inn, Coconut Grove, FL  - Hampton Inn, Seaport, NY - The Winter Haven, Miami, FL  - The Duane Street Hotel, NY - The Blue Moon, Miami, FL  - Hampton Inn, Pearl Street, NY - Courtyard, Miami, FL  - Holiday Inn Express, 29th Street, NY - The Parrot Key Hotel & Resort, Key West, FL  - Sheraton Hotel, JFK Airport, New York, NY - TownePlace Suites, Sunnyvale, CA  - Hilton Garden Inn, JFK Airport, New York, NY - The Ambrose Hotel, Santa Monica, CA  - NU Hotel, Brooklyn, NY - Courtyard, San Diego, CA  - Hyatt House White Plains, NY - The Pan Pacific Hotel, Seattle, WA  - Hampton Inn, Philadelphia, PA - Residence Inn, Tyson's Corner, VA  - The Rittenhouse, Philadelphia, PA - Hyatt House Gaithersburg, MD  - The Westin, Philadelphia, PA - Mystic Marriott Hotel & Spa, Groton, CT  - Sheraton, Wilmington South, DE  NOTE 5 – DEBT (CONTINUED)  The interest rate for borrowings under the Line of Credit and Term Loans are based on a pricing grid with a range of one month U.S. LIBOR plus a spread. The following table summarizes the balances outstanding and interest rate spread for each borrowing:      Outstanding Balance  Borrowing Spread December 31, 2017 December 31, 2016  Line of Credit 1.70% to 2.45% $ 16,100 $ -  First Term Loan 1.45% to 2.20% 225,000 210,520  Second Term Loan 1.50% to 2.25% 300,000 300,000  Third Term Loan 1.45% to 2.20% 193,900 156,100  From December 2012 to November 5, 2016, we maintained an interest rate swap, with a $150,000 notional amount, which effectively fixes the interest rate on $150,000 of the First Term Loan at a blended rate of 2.914% . This interest rate swap agreement matured on November 5, 2016.  On October 7, 2016 we entered into an interest rate swap associated with $150,000 of our $200,000 Third Term Loan. This swap effectively fixes the interest rate of the Third Term Loan at 3.211% and matures on October 3, 2019. See “Note 7 – Fair Value Measurements and Derivative Instruments” for more information regarding interest rate hedging strategies we employ.  On March 14, 2017, we entered into an interest rate swap associated with $50,000 of our $200,000 Third Term Loan, which became effective on April 3, 2017. This swap effectively fixes the interest rate on $50,000 of the Third Term Loan at 3.894%. This swap matures on October 3, 2019.  On March 23, 2017, we entered into an interest rate swap associated with our $300,000 Second Term Loan, which became effective beginning on August 10, 2017. This swap effectively fixes the interest rate of the Second Term Loan at 3.6930% from the effective date through August 9, 2018 . For the period from August 10, 2018 to August 11, 2019, the interest rate will be fixed at 4.1155%. For the period from August 12, 2019 through maturity, the interest rate will be fixed at 4.3925%. This swap matures on August 10, 2020.  The balance of the Term Loans is offset by $3,451 and $2,220 in net deferred financing costs as of December 31, 201 7 and December 31, 201 6 , respectively. These costs were incurred as a result of originating the term loan borrowings and are amortized over the life of these loans. The Credit Facility and the Term Loans include certain financial covenants and require that we maintain: (1) a minimum tangible net worth (calculated as total assets, plus accumulated depreciation, less total liabilities, intangibles and other defined adjustments) of $1,075,000 , plus an amount equal to 75% of the net cash proceeds of all issuances and primary sales of equity interests of the parent guarantor or any of its subsidiaries consummated following the closing date; (2) annual distributions not to exceed 95% of adjusted funds from operations; and (3) certain financial ratios, including the following:  · a fixed charge coverage ratio of not less than 1.50 to 1.00, · a maximum leverage ratio of not more than 60%; and · a maximum secured debt leverage ratio of 45%  The Company is in compliance with each of the covenants listed above as of December 31, 201 7 .

Interest incurred on mortgages and the revolving credit facility that relates to our capital improvement projects is capitalized through the date when the assets are placed in service. For the years ended December 31, 201 7 , 201 6 and 201 5 , we capitalized $76 , $ 0 and $0 respectively, of interest expense related to these projects.  Deferred Financing Costs  As noted above, c osts associated w ith entering into mortgages, notes payable , unsecured term loan and our credit facilities are deferred and amortized over the life of the debt instruments.

Commitments And Contingencies And Related Party Transactions [Abstract]
Commitments And Contingencies And Related Party Transactions	NOTE 6 – COMMITMENTS AND CONTINGENCIES AND RELATED PARTY TRANSACTIONS  Management Agreements  Our wholly-owned TRS, 44 New England Management Company, and certain of our joint venture entities engage eligible independent contractors in accordance with the requirements for qualification as a REIT under the Code including Hersha Hospitality Management Limited Partnership (“HHMLP”), as the property managers for hotels it leases from us pursuant to management agreements . HHMLP is owned, in part, by certain executives and trustees of the Company. Our management agreements with HHMLP provide for five -year terms and are subject to early termination upon the occurrence of defaults and certain other events described therein. As required under the REIT qualification rules, HHMLP must qualify as an “eligible independent contractor” during the term of the management agreements. Under the management agreements, HHMLP generally pays the operating expenses of our hotels. All operating expenses or other expenses incurred by HHMLP in performing its authorized duties are reimbursed or borne by our TRS to the extent the operating expenses or other expenses are incurred within the limits of the applicable approved hotel operating budget. HHMLP is not obligated to advance any of its own funds for operating expenses of a hotel or to incur any liability in connection with operating a hotel. Management agreements with other unaffiliated hotel management companies have similar terms.  For its services, HHMLP receives a base management fee and, if a hotel exceeds certain thresholds, an incentive management fee. The base management fee for a hotel is due monthly and is equal to 3% of gross revenues associated with each hotel managed for the related month. The incentive management fee, if any, for a hotel is due annually in arrears on the ninetieth day following the end of each fiscal year and is based upon the financial performance of the hotels. For the years ended December 31, 2017 , 2016 and 2015 , base management fees incurred totaled $ 13,447 , $13,048 and $13,675 respectively , and are recorded as Other Hotel Operating Expenses. For the years ended December 31, 2017 , 2016 and 2015 , we did no t incur incentive management fees.  Franchise Agreements  Our branded hotel properties are operated under franchise agreements assumed by the hotel property lessee. The franchise agreements have 10 to 20 year terms, but may be terminated by either the franchisee or franchisor on certain anniversary dates specified in the agreements. The franchise agreements require annual payments for franchise royalties, reservation, and advertising services, and such payments are based upon percentages of gross room revenue. These payments are paid by the hotels and charged to expense as incurred. Franchise fee expense s for the years ended December 31, 2017 , 2016 and 2015 were $23,645 , $24,477 and $27,998 respectively, and are recorded in Other Hotel Operating Expenses.

This right of first refusal would apply to each party until one year after such party ceases to be an officer or trustee of the Company. Our Acquisition Committee of the Board of Trustees is comprised solely of independent trustees, and the purchase prices and all material terms of the purchase of hotels from related parties are approved by the Acquisition Committee.

Fair Value Measurements And Derivative Instruments [Abstract]
Fair Value Measurements And Derivative Instruments	NOTE 7 – FAIR VALUE MEASUREMENTS AND DERIVATIVE INSTRUMENTS  Fair Value Measurements  Our determination of fair value measurements are based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, we utilize a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).  Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liabilities, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.  As of December 31, 201 7 , the Company’s derivative instruments represented the only financial instruments measured at fair value. Currently, the Company uses derivative instruments, such as interest rate swaps and caps, to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs.  We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees.  Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and the counterparties. However, as of December 31, 201 7 we have assessed the significance of the effect of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.  Derivative Instruments  The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and interest rate caps as part of its cash flow hedging strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. Interest rate caps designated as cash flow hedges limit the Company’s exposure to increased cash payments due to increases in variable interest rates. The table on the following page presents our derivative instruments as of December 31 , 2017 and 2 016.

This swap effectively fixes the interest rate of the Third Term Loan at 3.894% . This swap matures on October 3, 2019 .  (2) On March 23, 2017, we entered into an interest rate swap associated with our $300,000 Second Term Loan, which became effective beginning on August 10, 2017 . This swap effectively fixes the interest rate of the Second Term Loan at 3.6930% from the effective date through August 9, 2018. For the period from August 10, 2018 to August 11, 2019, the interest rate will be fixed at 4.1155% . For the period from August 12, 2019 through maturity, the interest rate will be fixed at 4.3925% . This swap matures on August 10, 2020 .  (3) On February 24, 2017, we refinanced the debt associated with the Hilton Garden Inn 52nd Street, New York, NY. As a result, we entered into an interest rate swap with a strike rate of 1.60%. The interest rate swap designated as a hedge a gainst the refinanced mortgage note matured on February 21, 2017.  (4) On August 1, 2017, we refinanced debt associated with the Courtyard, LA Westside, Culver City, CA. Concurrently, we entered into an interest rate swap with a strike rate of 1.683%. The interest rate cap designated as a hedge against the old refinanced mortgage note was due to mature on September 29, 2017 and was terminated upon the refinance.  NOTE 7 – FAIR VALUE MEASUREMENTS AND DERIVATIVE INSTRUMENTS (CONTINUED)  The fair value of certain swaps and our interest rate caps is included in other assets at December 31, 201 7 and December 31, 201 6 and the fair value of certain of our interest rate swaps is included in accounts payable, accrued expenses and other liabilities at December 31, 201 7 and December 31, 201 6 .  The net change in fair value of derivative instruments designated as cash flow hedges was a gain of $2,536 , a gain of $1,839 , and a loss of $108 for the years ended December 31, 201 7 , 201 6 and 201 5 , respectively. These unrealized gains and losses were reflected on our consolidated balance sheet in accumulated other comprehensive income.  Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate derivative. The change in net unrealized gains/losses on cash flow hedges reflects a reclassification of $594 of net unrealized gains/losses from accumulated other comprehensive income as an increase to interest expense during 201 7 . During 201 8 , the Company estimates that an additional $1,343 will be reclassified as an increase to interest expense.  Fair Value of Debt  The Company estimates the fair value of its fixed rate debt and the credit spreads over variable market rates on its variable rate debt by discounting the future cash flows of each instrument at estimated market rates or credit spreads consistent with the maturity of the debt obligation with similar credit policies. Credit spreads take into consideration general market conditions and maturity. The inputs utilized in estimating the fair value of debt are classified in Level 2 of the fair value hierarchy. As of December 31, 201 7 , the carrying value and estimated fair value of the Company’s debt were $1,093,013 and $1,073,190 , respectively. As of December 31, 201 6 , the carrying value and estimated fair value of the Company’s debt were $1,103,327 and $1,098,248 , respectively.

Share Based Payments [Abstract]
Share Based Payments	NOTE 8 – SHARE BASED PAYMENTS  We measure the cost of employee service received in exchange for an award of equity instruments based on the grant-date fair value of the award. The compensation cost is amortized on a straight line basis over the period during which an employee is required to provide service in exchange for the award. The compensation cost related to performance awards that are contingent upon market-based criteria being met is recorded at the fair value of the award on the date of the grant and amortized over the performance period. As discussed in Note 1 f orfeitures of share-based awards are expensed as they occur.  The Company established and our shareholders approved the Hersha Hospitality Trust 2012 Equity Incentive Plan, as amended, (the “2012 Plan”) for the purpose of attracting and retaining executive officers, employees, trustees and other persons and entities that provide services to the Company.  Executives & Employees  Annual Long Term Equity Incentive Programs  To further align the interests of the Company’s executives with those of shareholders, the Compensation Committee grants annual long term equity incentive awards that are both “performance based” and “time based.”  On March 10, 2017, the Compensation Committee approved the 2017 Annual Long Term Equity Incentive Program (“2017 Annual EIP”) for the executive officers, pursuant to which the executive officers are eligible to earn equity awards in the form of stock awards, LTIP Units, or performance share awards issuable pursuant to the 2012 Plan. These awards are earned under the 2017 Annual EIP based on achieving a threshold, target or maximum level of performance in the performance of RevPAR growth in certain defined areas. In addition, the Compensation Committee provided the option to the executive officers to elect shares in lieu of cash payment under the 2017 annual cash incentive program (“2017 ACIP”). The Company accounts for these grants as performance awards for which the Company assesses the probability of achievement of the performance conditions at the end of each period. As of December 31, 2017 , no shares or LTIP Units have been issued in accordance with the 2012 Plan to the executive officers in settlement of 2017 Annual EIP awards.   The following table is a summary of all unvested LTIP Units issued to executives:     Units Vested Unearned Compensation  Issuance Date Weighted Average Share Price LTIP Units Issued Vesting Period Vesting Schedule December 31, 2017 December 31, 2016 December 31, 2017 December 31, 2016  March 28, 2017  (2016 Annual EIP) $ 18.53 122,727 3 years 25%/year (1) 61,362 - $ 510 $ -  March 30, 2016  (2015 Annual EIP) 21.11 183,396 3 years 25%/year (1) 137,544 91,696 258 868  March 30, 2015  (2014 Annual EIP) 26.24 128,832 3 years 25%/year (1) 128,832 96,623 - 225  December 23, 2014 21.88 258,899 5 years 33% Year 3, 4, 5 (2) 258,899 172,599 - 457  693,854 586,637 360,918 $ 768 $ 1,550  (1) 25% of the issued shares or LTIP Units vested immediately upon issuance. In general, the remaining shares or LTIP Units vest 25% on the first through third anniversaries of the end of the performance period, which is a calendar year-end (subject to continuous employment through the applicable vesting date). (2) On April 18, 2012, the Company entered into amended and restated employment agreements with the Company’s executive officers. To induce the executives to agree to the substantial reduction in benefits upon certain terminations following a change of control as described in the agreements, the Company awarded an aggregate of 258,899 restricted common shares to the executives pursuant to the 2012 Plan, which were subsequently forfeited and replaced with LTIP Units on December 23, 2014. One-third of each award of LTIP Units vested or will vest on each of the third, fourth and fifth anniversaries of the original date of issuance. Vesting will accelerate upon a change of control or if the relevant executive’s employment with the Company were to terminate for any reason other than for cause (as defined in the employment agreements). NOTE 8 – SHARE BASED PAYMENTS (CONTINUED)  Stock based compensation expense related to the Annual Long Term Equity Incentive Prog ram s and 2017 ACIP of $6,062 , $4,800 and $4,490 was incurred during the years ended December 31, 201 7 , 201 6 and 201 5 , respectively. Unearned compens ation related to the Annual Long Term Equity Incentive Programs as of December 31, 201 7 and December 31, 201 6 was $768 and $1,550 , respectively.  Unearned compensation related to the grants and amortization of LTIP Units is included in Noncontrolling Interests on the Company’s Consolidated Balance Sheets and Consolidated Statements of Equity.  Multi-Year Long Term Equity Incentive Programs  On March 10, 2017, the Compensation Committee approved the 2017 Multi-Year Long Term Equity Incentive Program (“2017 Multi-Year EIP”). This program has a three -year performance period which commenced on January 1, 2017 and ends December 31, 2019. As of December 31, 2017, no shares or LTIP Units have been issued to the executive officers in settlement of 2017 Multi-Year EIP awards.  The following table is a summary of the approved Multi-Year Long Term Equity Incentive Programs:     Units Vested Unearned Compensation  Compensation Committee Approval Date Weighted Average Share Price LTIP Units Issued LTIP Issuance Date Performance Period December 31, 2017 December 31, 2016 December 31, 2017 December 31, 2016  March 10, 2017  (2017 Multi-Year EIP) $ 9.25 - N/A 1/1/2017 to 12/31/2019 - - $ 898 $ -  March 17, 2016  (2016 Multi-Year EIP) 11.25 - N/A 1/1/2016 to 12/31/2018 - - 592 888  March 18, 2015  (2015 Multi-Year EIP) 10.06 - N/A 1/1/2015 to 12/31/2017 - - 198 397  April 11, 2014  (2014 Multi-Year EIP) 14.38 61,057 3/28/2017 1/1/2014 to 12/31/2016 61,057 - - 283  61,057 61,057 - $ 1,688 $ 1,568  The shares or LTIP Units issuable under the Multi-Year Long Term Incentive Programs, including the 2017 Multi-Year EIP, are based on the Company’s achievement of a certain level of (1) absolute total shareholder return ( 37.50% of the award), (2) relative total shareholder return as compared to the Company’s peer group ( 37.50% of the award), and (3) relative growth in revenue per available room (RevPar) compared to the Company’s peer group ( 25% of the award).  The Company accounts for the total shareholder return components of these grants as market based awards where the Company estimates unearned compensation at the grant date fair value which is then amortized into compensation cost over the vesting period of each individual plan. The Company accounts for the RevPAR component of the grants as performance-based awards for which the Company assesses the probable achievement of the performance conditions at the end of the reporting period.  Stock based compensation expense of $ 1,598 , $1,869 and $818 was recorded for the years ended December 31, 201 7 , 201 6 and 201 5 , respe ctively, for the Multi-Year Long Term Equity Incentive Programs . Unearned compensation related to the multi-year program as of December 31, 201 7 and December 31, 201 6 , respectively, was $ 1,688 and $1, 568 . NOTE 8 – SHARE BASED PAYMENTS (CONTINUED)  Restricted Share Awards  In addition to share based compensation expense related to awards to executives under the Multi-Year and Annual Long Term Equity Incentive Programs, share based compensation expense related to restricted common shares issued to employees of the Company of $620 , $541 and $455 was incurred during the years ended December 31, 201 7 , 201 6 and 201 5 respectively. Unearned compensation related to the restricted share awards as of December 31, 201 7 and December 31, 201 6 was $648 and $505 , respectively.

Shareholders' Equity And Noncontrolling Interests In Partnership [Abstract]
Shareholders' Equity And Noncontrolling Interests In Partnership	NOTE 11 – SHAREHOLDERS’ EQUITY AND NONCONTROLLING INTERESTS IN PARTNERSHIP  Common Shares  The Company’s outstanding common shares have been duly authorized, and are fully paid and non-assessable. Common shareholders are entitled to receive dividends if and when authorized and declared by the Board of Trustees of the Company out of assets legally available and to share ratably in the assets of the Company legally available for distribution to its shareholders in the event of its liquidation, dissolution or winding up after payment of, or adequate provision for, all known debts and liabilities of the Company.  Preferred Shares  The Declaration of Trust authorizes our Board of Trustees to classify any unissued preferred shares and to reclassify any previously classified but unissued preferred shares of any series from time to time in one or more series, as authorized by the Board of Trustees. Prior to issuance of shares of each series, the Board of Trustees is required by Maryland REIT Law and our Declaration of Trust to set for each such series, subject to the provisions of our Declaration of Trust regarding the restriction on transfer of shares of beneficial interest, the terms, the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each such series. Thus, our Board of Trustees could authorize the issuance of additional preferred shares with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control in us that might involve a premium price for holders of common shares or otherwise be in their best interest.  Common Units  Common Units are issued in connection with the acquisition of wholly owned hotels and joint venture interests in hotel properties. The total number of Common Units outstanding as of December 31, 201 7 , 201 6 and 201 5 was 2,129,422 , 1,928,386 and 1,7 03,386 , respectively. These units can be redeemed for cash or converted to common shares, at the Company’s option, on a one-for-one basis.

Income Taxes [Abstract]
Income Taxes	NOTE 1 2 – INCOME TAXES  The Company elected to be taxed as a REIT under Sections 856 through 860 of the Code commencing with its taxable year ended December 31, 1999. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its REIT taxable income , determined without regard to the deduction for dividends paid and excluding net capital gain, to its shareholders. It is the Company’s current intention to adhere to these requirements and maintain the Company’s qualification for taxation as a REIT. As a REIT, the Company generally will not be subject to federal corporate income tax on that portion of its net income that is currently distributed to shareholders. If the Company fails to qualify for taxation as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax for taxable years prior to 2018 ) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income.  Taxable income from non-REIT activities managed through TRSs is subject to federal, state and local income taxes. As a TRS, 44 New England is subject to income taxes at the applicable federal, state and local tax rates.  The provision for income taxes differs from the amount of income tax determined by applying the applicable statutory federal income tax rate to pretax income from continuing operations as a result of the following differences:     For the year ended December 31,  2017 2016 2015  Statutory federal income tax provision $ 37,469 $ 39,633 $ 13,282  Adjustment for nontaxable income for Hersha Hospitality Trust (37,670) (44,078) (15,853)  Remeasurement of net deferred tax asset - Tax Cuts & Jobs Act 4,601 - -  State income taxes, net of federal income tax effect 338 (725) (581)  Recognition of deferred tax assets 524 282 11   Total income tax expense (benefit) $ 5,262 $ (4,888) $ (3,141)  The Tax Cuts and Jobs Act was enacted on December 22, 2017 and institutes significant changes to the federal income tax law. Effective January 1, 2018, the U.S. statutory rate applicable to the Company decreases from 34% to 21% . As a result of the decrease in statutory rate, our deferred tax assets and liabilities that will apply to future periods were remeasured as of December 31, 2017. We recognized a deferred tax expense of $4,601 to reflect this change in the tax rate.  NOTE 12 – INCOME TAXES (CONTINUED)  The components of the Company’s income tax expense (benefit) from continuing operations for the years ended December 31, 201 7 , 201 6 and 201 5 were as follows:    For the year ended December 31,  2017 2016 2015  Income tax expense (benefit):  Current:  Federal $ - $ - $ -  State - - -  Deferred:  Federal 4,750 (3,790) (2,261)  State 512 (1,098) (880)  Total $ 5,262 $ (4,888) $ (3,141)   Income tax expense (benefit):  From continuing operations 5,262 (4,888) (3,141)  From discontinued operations - - -  Total $ 5,262 $ (4,888) $ (3,141)  The components of consolidated TRS’s net deferred tax asset as of December 31, 201 7 and 201 6 were as follows:     As of December 31,  2017 2016  Deferred tax assets:  Net operating loss carryforwards $ 9,881 $ 18,448  Accrued expenses and other 1,438 1,494  Tax credit carryforwards 444 567  Total gross deferred tax assets 11,763 20,509  Valuation allowance (497) (804)  Total net deferred tax assets $ 11,266 $ 19,705  Deferred tax liabilities:  Depreciation and amortization 332 3,508  Total Net deferred tax assets $ 10,934 $ 16,197  In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on limitations related to the utilization of certain tax attribute carryforwards, the Company recorded a valuation allowance of approximately $497 as these attributes are not more likely than not to be realized prior to their expiration. Based on the level of historical taxable income, tax planning strategies and projections for future taxable income over the periods in which the remaining deferred tax assets are deductible, Management believes it is more likely than not that the remaining deferred tax assets will be realized. As of December 31, 201 7 , we have gross federal net operating loss carryforwards of $ 36,829 which expire over various periods from 2023 through 203 6 . As of December 31, 201 7 , we have gross state net operating loss carryforwards of $ 38,492 which expire over various periods from 201 8 to 203 6 . The Company has tax credits of $ 444 available which begin to expire in 2028.  NOTE 12 – INCOME TAXES (CONTINUED)  Earnings and profits, which will determine the taxability of distributions to shareholders, will differ from net income reported for financial reporting purposes due to the differences for federal tax purposes in the estimated useful lives and methods used to compute depreciation. The following table sets forth certain per share information regarding the Company’s common and preferred share distributions for the years ended December 31, 201 7 , 201 6 and 201 5 .     2017 2016 2015  Preferred Shares - 8% Series B  Ordinary income N/A 100.00% 100.00%  Return of Capital N/A 0.00% 0.00%  Capital Gain Distribution N/A 0.00% 0.00%  Preferred Shares - 6.875% Series C  Ordinary income 100.00% 100.00% 100.00%  Return of Capital 0.00% 0.00% 0.00%  Capital Gain Distribution 0.00% 0.00% 0.00%  Preferred Shares - 6.5% Series D  Ordinary income 100.00% 100.00% N/A  Return of Capital 0.00% 0.00% N/A  Capital Gain Distribution 0.00% 0.00% N/A  Preferred Shares - 6.5% Series E  Ordinary income 100.00% N/A N/A  Return of Capital 0.00% N/A N/A  Capital Gain Distribution 0.00% N/A N/A  Common Shares - Class A  Ordinary income 70.95% 100.00% 79.49%  Return of Capital 29.05% 0.00% 20.51%  Capital Gain Distribution 0.00% 0.00% 0.00%

Organization And Summary Of Significant Accounting Policies [Abstract]
Collaborative Arrangement, Accounting Policy	Hersha Hospitality Trust (“we” or the “Company”) was formed in May 1998 as a self-administered, Maryland real estate investment trust. We have elected to be taxed and expect to continue to elect to be taxed as a real estate investment trust, or REIT, for federal income tax purposes.  The Company owns a controlling general partnership interest in Hersha Hospitality Limited Partnership (“HHLP” or the “Partnership”), which owns a 99% limited partnership interest in various subsidiary partnerships. Hersha Hospitality, LLC (“HHLLC”), a Virginia limited liability company, owns a 1% general partnership interest in the subsidiary partnerships and the Partnership is the sole member of HHLLC.  The Partnership owns a taxable REIT subsidiary (“TRS”), 44 New England Management Company (“44 New England” or “TRS Lessee”), which leases certain of the Company’s hotels.  Hersha’s common shares of beneficial interest trade on the New York Stock Exchange (“the NYSE”) under the ticker symbol "HT", its 6.875% Series C Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRC”, its 6.500% Series D Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRD”, and it’s 6.500% Series E Cumulative Redeemable Preferred Shares of Beneficial Interest trade on the NYSE under the ticker symbol “HT PRE.”  As of December 31, 2017, the Company, through the Partnership and subsidiary partnerships, wholly owned 41 limited and full service hotels. All of the wholly owned hotel facilities are leased to the Company’s TRS, 44 New England.  In addition to the wholly owned hotel properties, as of December 31, 2017, the Company owned joint venture interests in another nine properties. The properties owned by the joint ventures are leased to a TRS owned by the joint venture or to an entity owned by the joint venture partners and 44 New England. The following table lists the properties owned by these joint ventures:     Joint Venture Property Location Lessee/Sublessee   Unconsolidated Joint Ventures  Cindat Hersha Owner JV, LLC (1) Hampton Inn Herald Square, NY Cindat Hersha Lessee JV, LLC  Hampton Inn Chelsea, NY Cindat Hersha Lessee JV, LLC  Hampton Inn Times Square, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Express Times Square, NY Cindat Hersha Lessee JV, LLC  Candlewood Suites Times Square, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Wall Street, NY Cindat Hersha Lessee JV, LLC  Holiday Inn Express Water Street, NY Cindat Hersha Lessee JV, LLC  SB Partners, LLC (2) Holiday Inn Express South Boston, MA South Bay Sandeep, LLC  Hiren Boston, LLC (2) Courtyard South Boston, MA South Bay Boston, LLC  (1) Our common ownership interest in the CINDAT JV equals 30% at December 31, 2017. As of December 31, 2017, we owned a $43,194 preferred equity interest in the joint venture. See Note 3 – Investment in Unconsolidated Joint Ventures for a more detailed explanation of our ownership interest and the related distribution of earnings within the venture.  (2) Our common ownership interest in SB Partners, LLC and Hiren Boston, LLC equals 50% .  At December 31, 2016, Mystic Partners, LLC owned an interest in three hotel properties. Our interest in Mystic Partners, LLC is relative to our interest in each of the three properties owned by the joint venture as defined in the joint venture’s governing documents. Each of the three properties owned by Mystic Partners, LLC is leased to a separate entity that is consolidated in Mystic Partners Leaseco, LLC which is owned by 44 New England and our joint venture partner in Mystic Partners, LLC.  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  On January 3, 2017, we transferred to our joint venture partner all of our partnership interests in the Hartford Marriott and the Hartford Hilton for $8.5 million, which represents a 100% recovery of our equity investment in these assets. We also simultaneously assumed full ownership of the Mystic Marriott Hotel & Spa without any additional cash payment to the joint venture partner.  The properties are managed by eligible independent management companies, including Hersha Hospitality Management, LP (“HHMLP”). HHMLP is owned in part by certain of our trustees and executive officers and other unaffiliated third party investors.
Principles Of Consolidation And Presentation	Principles of Consolidation and Presentation  The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and include all of our accounts as well as accounts of the Partnership, subsidiary partnerships and our wholly owned TRS Lessee. All significant inter-company amounts have been eliminated.  Consolidated properties are either wholly owned or owned less than 100% by the Partnership and are controlled by the Company as general partner of the Partnership. Properties owned in joint ventures are also consolidated if the determination is made that we are the primary beneficiary in a variable interest entity (VIE) or we maintain control of the asset through our voting interest in the entity. Control can be demonstrated when the general partner has the power to impact the economic performance of the partnership, which includes the ability of the general partner to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the limited partners and the inability of the limited partners to replace the general partner. Control can be demonstrated by the limited partners if the limited partners have the right to dissolve or liquidate the partnership or otherwise remove the general partner without cause or have rights to participate in the significant decisions made in the ordinary course of the partnership’s business. We evaluate each of our investments and contractual relationships to determine whether they meet the guidelines for consolidation. Entities are consolidated if the determination is made that we are the primary beneficiary in a VIE or we maintain control of the asset through our voting interest or other rights in the operation of the entity. To determine if we are the primary beneficiary of a VIE, we evaluate whether we have a controlling financial interest in that VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE. Control can also be demonstrated by the ability of a member to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the other member and the inability of the members to replace the managing member. Based on our examination, the following entities were determined to be VIE’s: HHLP; Cindat Hersha Lessee JV, LLC; South Bay Boston, LLC; Hersha Statutory Trust I; and Hersha Statutory Trust II. As noted, HHLP meets the criteria as a VIE. The Company’s most significant asset is its investment in HHLP, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of HHLP. Cindat Hersha Lessee JV, LLC is a VIE that leases hotel property. The entity is consolidated by the lessors, the primary beneficiary. Our maximum exposure to losses due to our investment in Cindat Hersha Owner JV, LLC is limited to our investment in the joint venture which is $0 as of December 31, 2017. Also, South Bay Boston, LLC lease s hotel property is a VIE. The entity is consolidated by the lessors, the primary beneficiary. Hersha Statutory Trust I and Hersha Statutory Trust II are VIEs but HHLP is not the primary beneficiary in these entities. Accordingly, the accounts of Hersha Statutory Trust I and Hersha Statutory Trust II are not consolidated. On September 2, 2016, we exercised our option to acquire the non-controlling equity interests in Brisam Management DE, LLC (“Brisam”), the entity which owns the real estate assets of the Holiday Inn Express, New York, NY. We paid approximately $2,318 to exercise this option. Prior to the exercise of this option, we had consolidated Brisam, a variable interest entity, in our financial statements as we determined we were the primary beneficiary.  We allocate resources and assess operating performance based on individual hotels and consider each one of our hotels to be an operating segment. No operating segment, individually, meets the threshold for a reportable segment as defined within ASC Topic 280 – Segment Reporting, nor do they fully satisfy the requisite aggregation criteria therein. As a result, the Company does not present separate operating segment information within the Notes to the Consolidated Financial Statements.
Use Of Estimates	Use of Estimates  The preparation of financial statements in conformity with accounting principles generally accepted in the United States (US GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.  Although we believe the assumptions and estimates we made are reasonable and appropriate, as discussed in the applicable sections throughout these Consolidated Financial Statements, different assumptions and estimates could materially impact our reported results.
Investment In Hotel Properties	Investment in Hotel Properties  The Company records the value of hotel properties acquired based on the fair value of the acquired real estate, furniture, fixtures and equipment, and intangible assets and the fair value of liabilities assumed, including debt. The fair value allocations were determined using Level 3 inputs, which are typically unobservable and are based on our own assumptions, as there is little, if any, related market activity. The Company’s investments in hotel properties are carried at cost and are depreciated using the straight-line method over the following estimated useful lives:  Building and Improvements 7 to 40 Years Furniture, Fixtures and Equipment 2 to 7 Years The Company periodically reviews the carrying value of each hotel to determine if circumstances indicate impairment to the carrying value of the investment in the hotel or that depreciation periods should be modified. If facts or circumstances indicate the possibility of impairment, the Company will prepare an estimate of the undiscounted future cash flows, without interest charges, of the specific hotel. Based on the property’s undiscounted future cash flows, the Company will determine if the investment in such hotel is recoverable. If impairment is indicated, an adjustment will be made to reduce the carrying value of the hotel to reflect its fair value.  We consider a hotel to be held for sale when management and our independent trustees commit to a plan to sell the property, the property is available for sale, management engages in an active program to locate a buyer for the property and it is probable the sale will be completed within a year of the initiation of the plan to sell.  Acquisition-related cost, such as due diligence, legal and accounting fees, are not capitalized or applied in determining the fair value of the above acquired assets.
Investment In Unconsolidated Joint Ventures	Investment in Unconsolidated Joint Ventures  If it is determined that we do not have a controlling interest in a joint venture, either through our financial interest in a VIE or our voting interest in a voting interest entity, the equity method of accounting is used. Under this method, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, limited to the extent of our investment in, advances to and commitments for the investee. Pursuant to our joint venture agreements, allocations of profits and losses of some of our investments in unconsolidated joint ventures may be allocated disproportionately as compared to nominal ownership percentages due to specified preferred return rate thresholds. See Note 3 – Investment in Unconsolidated Joint Ventures for a more detailed explanation of the methodology used in determining the allocation of profits and losses within our joint ventures.  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, we will estimate the fair value of the investment. Our estimate of fair value takes into consideration factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and 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 the impairment is considered other than temporary, the loss will be measured as the excess of the carrying amount over the fair value of our investment in the unconsolidated joint venture.
Cash And Cash Equivalents	Cash and Cash Equivalents  Cash and cash equivalents represent cash on hand and in banks plus short-term investments with an initial maturity of three months or less when purchased.
Escrow Deposits	Escrow Deposits  Escrow deposits include reserves for debt service, real estate taxes, and insurance and reserves for furniture, fixtures, and equipment replacements, as required by certain mortgage debt agreement restrictions and provisions.
Hotel Accounts Receivable	Hotel Accounts Receivable  Hotel accounts receivable consists primarily of meeting and banquet room rental and hotel guest receivables. The Company generally does not require collateral. Ongoing credit evaluations are performed and an allowance for potential losses from uncollectible accounts is provided against the portion of accounts receivable that is estimated to be uncollectible.
Deferred Financing Costs	Deferred Financing Costs  Deferred financing costs are recorded at cost and amortized over the terms of the related indebtedness using the effective interest method.
Due From/To Related Parties	Due from/to Related Parties  Due from/to Related Parties represents current receivables and payables resulting from transactions related to hotel management and project management with affiliated entities. Due from related parties results primarily from advances of shared costs incurred. Due to affiliates results primarily from hotel management and project management fees incurred. Both due to and due from related parties are generally settled within a period not to exceed one year.
Intangible Assets and Liabilities	Intangible Assets and Liabilities  Intangible assets consist of leasehold intangibles for above-market value of in-place leases and deferred franchise fees. The leasehold intangibles are amortized over the remaining lease term. Deferred franchise fees are amortized using the straight-line method over the life of the franchise agreement.  Intangible liabilities consist of leasehold intangibles for below-market value of in-place leases. The leasehold intangibles are amortized over the remaining lease term. Intangible liabilities are included in the accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets.
Development Project Capitalization	Development Project Capitalization  We have opportunistically engaged in the development and re-development of hotel assets. We capitalize expenditures related to hotel development projects and renovations, including indirect costs such as interest expense, real estate taxes and utilities related to hotel development projects and renovations.
Noncontrolling Interest	Noncontrolling Interest  Noncontrolling interest in the Partnership represents the limited partner’s proportionate share of the equity of the Partnership. Income (loss) is allocated to noncontrolling interest in accordance with the weighted average percentage ownership of the Partnership during the period. At the end of each reporting period the appropriate adjustments to the income (loss) are made based upon the weighted average percentage ownership of the Partnership during the period. Our ownership interest in the Partnership as of December 31, 2017, 2016 and 2015 was 92.5% , 93.6% , and 95.0% , respectively.  We define a noncontrolling interest as the portion of equity in a subsidiary not attributable, directly or indirectly, to a parent.  Such noncontrolling interests are reported on the consolidated balance sheets within equity, but separately from the shareholders’ equity. Revenues, expenses and net income or loss attributable to both the Company and noncontrolling interests are reported on the consolidated statements of operations. NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  In accordance with US GAAP, we classify securities that are redeemable for cash or other assets at the option of the holder, or not solely within the control of the issuer, outside of permanent equity in the consolidated balance sheet. The Company makes this determination based on terms in applicable agreements, specifically in relation to redemption provisions. Additionally, with respect to noncontrolling interests for which the Company has a choice to settle the contract by delivery of its own shares, the Company considers the guidance in US GAAP to evaluate whether the Company controls the actions or events necessary to issue the maximum number of common shares that could be required to be delivered at the time of settlement of the contract.  We classify the noncontrolling interests of our consolidated variable interest entity, and certain Common Units (“Nonredeemable Common Units”) as equity. The noncontrolling interests of Nonredeemable Common Units totaled $54,286 as of December 31, 2017 and $44,321 as of December 31, 2016. As of December 31, 2017, there were 3,223,366 Nonredeemable Common Units outstanding with a fair market value of $56,087 , based on the price per share of our common shares on the NYSE on such date.  In accordance with the partnership agreement of the Partnership, holders of these units may redeem them for cash unless we, in our sole and absolute discretion, elect to issue common shares on a one-for-one basis in lieu of paying cash.  Net income or loss attributed to Nonredeemable Common Units and Redeemable Common Units (collectively, “Common Units”), as well as the net income or loss related to the noncontrolling interests of our consolidated variable interest entity, is included in net income or loss in the consolidated statements of operations. Net income or loss attributed to the Common Units and the noncontrolling interests of our consolidated joint ventures and consolidated variable interest entity is excluded from net income or loss applicable to common shareholders in the consolidated statements of operations.
Shareholders' Equity	Shareholders’ Equity  On May 31, 2016, we completed a public offering of 7,700,000 (including 700,000 overallotment shares sold on June 14, 2016) 6.50% Series D Cumulative Redeemable Preferred Shares. These shares have a par value of $0.01 per share with a $25.00 liquidation preference per share. Net proceeds of the offering, after deducting the underwriting discount and the offering expenses payable by us, were approximately $185,999 . We utilized the net proceeds of the offering to redeem all outstanding 8.00% Series B Cumulative Redeemable Preferred Shares on June 8, 2016, and for general corporate purposes.  Shares of our 8.00% Series B Cumulative Redeemable Preferred Shares were redeemed at a per share redemption price of $25.00 together with accrued and unpaid dividends to the redemption date for an aggregate per share redemption price of $25.3722 . Dividends ceased accruing on the Series B Preferred Shares on June 8, 2016.  On November 7, 2016, we completed a public offering of 4,000,000 6.50% Series E Cumulative Redeemable Preferred Shares. These shares have a par value of $0.01 per share with a $25.00 liquidation preference per share. Net proceeds of the offering, after deducting the underwriting discount and the offering expenses payable by us, were approximately $96,585 . We utilized the net proceeds of the offering for general corporate purposes.  Terms of the Series C, Series D and Series E Preferred Shares outstanding at December 31, 2017 and 2016 are summarized as follows:     Dividend Per Share  Shares Outstanding Year Ended December 31,  Series December 31, 2017 December 31, 2016 Aggregate Liquidation Preference Distribution Rate 2017 2016  Series C 3,000,000 3,000,000 $ 75,000 6.875% $ 1.7188 $ 1.7188  Series D 7,701,700 7,700,000 $ 192,500 6.500% $ 1.6250 1.0157  Series E 4,000,000 4,000,000 $ 100,000 6.500% $ 1.6250 0.3069  Total 14,701,700 14,700,000  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  On December 23, 2014, we amended our partnership agreement to allow for the issuance of profits interests in HHLP in the form of LTIP Units, a new class of limited partnership units in HHLP, and to establish the terms of the LTIP Units. The LTIP Units vest on December 31 and June 1 of each year, beginning on December 31, 2014 and ending on June 1, 2017. The LTIP Units contain restricted stock awards that were forfeited and replaced with LTIP Unit awards with similar terms. The total number of Restricted Stock Awards forfeited and LTIP Units awarded was 1,948,324 .  In October 2016, our Board of Trustees authorized a new share repurchase from time to time up to an aggregate of $100,000 of our outstanding shares. For the year ended December 31, 2017, the Company repurchased 1,991,573 common shares for an aggregate purchase price of $35,178 under the October 2016 repurchase programs. Upon repurchase by the Company, these common shares ceased to be outstanding and became authorized but unissued common shares.  In April 2017, we entered into Equity Distribution Agreements with four investment banks whereby we agreed to sell up to 8,000,000 Class A common shares, up to 1,000,000 Series D Cumulative Redeemable Preferred Shares, and up to 1,000,000 Series E Cumulative Redeemable Preferred Shares from time to time in an “at the market” offering. In conjunction with this transaction, the Company increased the number of authorized Class A common shares from 90,000,000 to 104,000,000 . For the year ended December 31, 2017, we issued 1,700 Series D Preferred Shares through this program.  In December 2017, our Board of Trustees authorized a new share repurchase program for up to $100,000 of common shares which commenced on January 1, 2018. We expect to complete the new repurchase program prior to December 31, 2018, unless extended by our Board of Trustees.
Stock Based Compensation	Stock Based Compensation  We measure the cost of employee service received in exchange for an award of equity instruments based on the grant-date fair value of the award. The compensation cost is amortized on a straight line basis over the period during which an employee is required to provide service in exchange for the award. The compensation cost related to performance awards that are contingent upon market-based criteria being met is recorded at the fair value of the award on the date of the grant and amortized over the performance period.
Derivatives And Hedging	Derivatives and Hedging  The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and interest rate caps as part of its cash flow hedging strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. Interest rate caps designated as cash flow hedges limit the Company’s exposure to increased cash payments due to increases in variable interest rates.
Revenue Recognition	Revenue Recognition We recognize revenue and expense for all consolidated hotels as hotel operating revenue and hotel operating expense when earned and incurred. These revenues are recorded net of any sales or occupancy taxes collected from our guests. We participate in frequent guest programs sponsored by the brand owners of our hotels and we expense the charges associated with those programs, as incurred.  Other revenues consist primarily of fees earned for asset management services provided to hotels we own through unconsolidated joint ventures. Fees are earned as a percentage of hotel revenue and are recorded in the period earned to the extent of the noncontrolling interest ownership.
Income Taxes	NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  Income Taxes  The Company has elected to be taxed as a REIT under applicable provisions of the Internal Revenue Code of 1986, as amended, or the Code, and intends to continue to qualify as a REIT. In general, under such provisions, a trust which has made the required election and, in the taxable year, meets certain requirements and distributes to its shareholders at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains, will not be subject to federal income tax to the extent of the income which it distributes. Earnings and profits, which determine the taxability of dividends to shareholders, differ from net income reported for financial reporting purposes due primarily to differences in depreciation of hotel properties for federal income tax purposes.  Deferred income taxes relate primarily to the TRS Lessee and are accounted for using the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial reporting bases of assets and liabilities of the TRS Lessee and their respective tax bases and for their operating loss and tax credit carry forwards based on enacted tax rates expected to be in effect when such amounts are realized or settled. However, deferred tax assets are recognized only to the extent that it is more likely than not that they will be realized based on consideration of available evidence, including tax planning strategies and other factors.  The Company may recognize a tax benefit from an uncertain tax position when it is more-likely-than-not (defined as a likelihood of more than 50%) that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. If a tax position does not meet the more-likely-than-not recognition threshold, despite the Company’s belief that its filing position is supportable, the benefit of that tax position is not recognized in the statements of operations. The Company recognizes interest and penalties, as applicable, related to unrecognized tax benefits as a component of income tax expense. The Company recognizes unrecognized tax benefits in the period that the uncertainty is eliminated by either affirmative agreement of the uncertain tax position by the applicable taxing authority, or by expiration of the applicable statute of limitation. For the years ended December 31, 2017, 2016 and 2015, the Company did no t record any uncertain tax positions. As of December 31, 2017, with few exceptions, the Company is subject to tax examinations by federal, state, and local income tax authorities for years 2003 through 2017.
Reclassification	Reclassification  Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. 
New Accounting Pronouncements	New Accounting Pronouncements  In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The update will make more financial and nonfinancial hedging strategies eligible for hedge accounting, changes how companies assess hedge effectiveness, and amends the presentation and disclosure requirements for hedging transactions. The provisions of the update will be effective for the Company starting January 1, 2019 with the early adoption available. Based on the type of derivative instruments within the Company’s portfolio, we do not anticipate this update to have a material effect on our consolidated financial statements and related disclosures, however, we are currently assessing the ultimate impact of this update.  In February 2017, the FASB issued ASU No. 2017-05, Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) . The update defines the term “in substance nonfinancial asset” as it is presented in Subtopic 610-20 as a “financial asset promised to a counterparty in a contract if substantially all of the fair value of the assets that are promised to the counterparty in the contract is concentrated in nonfinancial assets.” As it relates to the Company, real estate, such as land and building, would be considered an example of a nonfinancial asset. Additionally, the update provides guidance over partial sale transactions, particularly, when an entity should derecognize a distinct nonfinancial asset or in substance nonfinancial asset in a partial sale transaction, and the extent of gain that should be recognized as a result of the partial sale transaction. This standard is effective in conjunction with ASU No. 2014-09 (presented below), which is effective for periods beginning after December 15, 2017 and the Company will adopt effective January 1, 2018, the same time as the adoption of ASU No. 2014-09. The Company has considered how the provisions of this update affect our adoption of ASU No. 2014-09. See below for our discussion of ASU No. 2014-09 and the effect it will have on our consolidated financial statements and related disclosures. NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business , which clarifies the definition of a business as it relates to acquisitions and business combinations. The update adds further guidance that assists preparers in evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. We expect most of our hotel property acquisitions to qualify as asset acquisitions under the standard which requires the capitalization of acquisition costs to the underlying assets. The Company expects the standard to have an impact on our financial statements in periods during which we complete significant hotel acquisitions. For instance, during the year ended December 31, 2017, the Company incurred $2,203 in expenses related to acquisition costs that would have been subject to capitalization under this ASU. This standard is effective for periods beginning after December 31, 2017, and the Company will adopt it effective January 1, 2018.  Effective January 1, 2017, we adopted ASU No. 2016-09, Improvements to Employee Share-Based Award Payment Accounting , which simplifies various aspects of how share-based payments are accounted for and presented in the financial statements. This standard requires companies to record all of the tax effects related to share-based payments through the income statement, allows companies to elect an accounting policy to either estimate the share based award forfeitures (and expense) or account for forfeitures (and expense) as they occur, and allows companies to withhold a percentage of the shares issuable upon settlement of an award up to the maximum individual statutory tax rate without causing the award to be classified as a liability. The Company has elected to expense forfeitures of share-based award as they occur as our accounting policy. The adoption of ASU No. 2016-09 had no material impact on our consolidated financial statements and related disclosures.  In November 2016 the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) , which provides guidance on the presentation of restricted cash or restricted cash equivalents within the statement of cash flows. Accordingly, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This standard is effective for the Company for periods beginning after December 15, 2017. The adoption of ASU No. 2016-18 will change the presentation of the statement of cash flows for the Company and we will utilize a retrospective transition method for each period presented within financial statements for periods subsequent to the date of adoption.  In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which provides the principles for the recognition, measurement, presentation and disclosure of leases. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that certain initial direct costs be expensed rather than capitalized. Under the standard, lessees apply a dual approach, classifying leases as either finance or operating leases. A lessee is required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months, regardless of their lease classification. Based on the review of our leases, we are a lessee on ground leases in certain markets, hotel equipment leases, and office space leases. We are also a lessor in certain office space and retail lease agreements related to our hotels. While we do not anticipate any material change to the accounting for leases under which we are a lessor, we are still evaluating the impact this ASU will have on the accounting for our leasing arrangements as well as our disclosures within the notes to our financial statements. This standard will be effective for the first annual reporting period beginning after December 15, 2018.  NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  On May 28, 2014, the FASB issued ASU No. 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. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or modified retrospective transition method. The modified retrospective method allows for, among other things, a cumulative adjustment to opening equity upon adoption of the standard. The Company will utilize the modified retrospective transition method along with the available practical expedients upon adoption of ASU No. 2014-09. We evaluated each of our revenue streams and related recognition under the standard. Based on our analysis to date, we do not expect the new revenue recognition model to have a material impact on our hotel operating revenue, including room revenue, food and beverage, and other revenue. Our evaluation under the standard also includes sales to third parties, primarily a result of dispositions of real estate. Our evaluation over sales of real estate is impacted by the FASB definition of a business and in substance nonfinancial assets, which have recently been addressed through the issuance of ASU No. 2017-01 and ASU No. 2017-05, respectively. Based on the provisions of ASU No. 2017-01 and ASU No. 2017-05, the Company expects any future sales of interests or partial interests in hotel properties resulting in gains to likely meet the criteria for full gain recognition. This treatment is not different from our historical position when selling our entire interest in hotel properties, however, this is different than the historical treatment in certain instances where the Company sold partial interests in hotel properties. In particular, during 2016 the Company sold partial interests in seven hotel properties to a third party (“Cindat Sale”) resulting in an approximate $81 million deferred gain based on prevailing GAAP at the time of the transaction. As permitted under the available practical expedients, the Company will apply existing accounting principles for the impacts of any contracts that are determined to be closed contracts at the date of adoption. Accordingly, the Company analyzed the Cindat Sale to assess whether it meets the definition of a closed contract under the guidance of ASU No. 2014-09 and concluded it is a closed contract. Accordingly, there will be no change to the deferred gain amount recorded in conjunction with the Cindat Sale and the Company will continue to follow existing GAAP for the transaction.

(2) On April 18, 2012, the Company entered into amended and restated employment agreements with the Company’s executive officers. To induce the executives to agree to the substantial reduction in benefits upon certain terminations following a change of control as described in the agreements, the Company awarded an aggregate of 258,899 restricted common shares to the executives pursuant to the 2012 Plan, which were subsequently forfeited and replaced with LTIP Units on December 23, 2014. One-third of each award of LTIP Units vested or will vest on each of the third, fourth and fifth anniversaries of the original date of issuance. Vesting will accelerate upon a change of control or if the relevant executive’s employment with the Company were to terminate for any reason other than for cause (as defined in the employment agreements).

[1]	Income (loss) allocated to noncontrolling interest in HHLP has been excluded from the numerator and Common Units and Vested LTIP Units have been omitted from the denominator for the purpose of computing diluted earnings per share since including these amounts in the numerator and denominator would have no impact. In addition, potentially dilutive common shares, if any, have been excluded from the denominator if they are anti-dilutive to income (loss) applicable to common shareholders.
[2]	* Assets are depreciated over a 7 to 40 year life, upon which the latest income statement is computed.
[3]	Income allocated to noncontrolling interest in Hersha Hospitality Limited Partnership (the "Operating Partnership" or "HHLP") has been excluded from the numerator and the Class A common shares issuable upon any redemption of the Operating Partnership's common units of limited partnership interest ("Common Units") and the Operating Partnership's vested LTIP units ("Vested LTIP Units") have been omitted from the denominator for the purpose of computing diluted earnings per share because the effect of including these shares and units in the numerator and denominator would have no impact.

[1]	Income (loss) allocated to noncontrolling interest in HHLP has been excluded from the numerator and Common Units and Vested LTIP Units have been omitted from the denominator for the purpose of computing diluted earnings per share since including these amounts in the numerator and denominator would have no impact. In addition, potentially dilutive common shares, if any, have been excluded from the denominator if they are anti-dilutive to income (loss) applicable to common shareholders.
[2]	* Assets are depreciated over a 7 to 40 year life, upon which the latest income statement is computed.
[3]	Income allocated to noncontrolling interest in Hersha Hospitality Limited Partnership (the "Operating Partnership" or "HHLP") has been excluded from the numerator and the Class A common shares issuable upon any redemption of the Operating Partnership's common units of limited partnership interest ("Common Units") and the Operating Partnership's vested LTIP units ("Vested LTIP Units") have been omitted from the denominator for the purpose of computing diluted earnings per share because the effect of including these shares and units in the numerator and denominator would have no impact.
