SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	NOTE 2:- SIGNIFICANT ACCOUNTING POLICIES a. Basis of presentation of the financial statements: The preparation of financial statements in conformity with U.S generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. b. Functional currency, presentation currency and foreign currency: The presentation currency of the financial statements is the U.S. dollar. The functional currency of the Company is the U.S Dollar. The functional currencies of Optibase's subsidiaries are U.S dollar, CHF and EUR. Assets and liabilities of these subsidiaries are translated at the year-end exchange rates and their statement of operations items are translated using the average exchange rates for all periods presented. The resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income in shareholders' equity. c. Principles of consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation. d. Non-controlling interests: Non-controlling interests generally represent the portion of equity that the Company does not own in the consolidated entities. The Company accounts for and reports its non-controlling interests in accordance with the provisions required under the Consolidation Topic of the FASB ASC 810. Non-controlling interests are separately presented within the equity section of the consolidated balance sheets. The amounts of consolidated net earnings attributable to the Company and to the non-controlling interests are presented on the consolidated statement of operations. e. Cash equivalents: Cash equivalents include short-term, highly liquid investments that are readily convertible to cash, with original maturities of three months or less at the date acquired. f. Property: Real estate properties are stated at cost net of accumulated depreciation. Costs include those related to acquisition, including building improvements. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: Years Building 25 - 63 Buildings' improvements 5 - 20 Condominium units 30 g. Impairment of long-lived assets, right-of-use assets and intangible assets: The Group's long-lived assets (assets group) to be held or used, including property and equipment, right of use assets and intangible assets subject to amortization are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment" and ASC 350, “Intangibles - Goodwill and other”, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In assessing the recoverability of long-lived assets, the Company makes judgments regarding whether impairment indicators exist based on legal factors, market conditions and operating performances of assets or asset groups. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured by the carrying amount of the assets exceeds the fair value of the assets. The Company reviews assets on a component-level basis, which is the lowest level of assets for which there are identifiable cash flows that can be distinguished operationally and for financial reporting purposes. The carrying amount of the asset was compared with the related expected undiscounted future cash flows to be generated by those assets over the estimated remaining useful life of the primary asset. In cases where the expected undiscounted future cash flows were less than the carrying amounts of the assets, those assets were considered impaired and written down to their fair values. Fair value was established based on discounted cash flows. As of December 31, 2019 and 2018, no impairment losses have been identified. h. Investments in companies: Investments in non-marketable equity securities of companies in which the Company does not have control or the ability to exercise significant influence over their operation and financial policies are recorded at cost. The management evaluates investments in non-marketable equity securities as evidence of other-than temporary declines in value. When relevant factors indicate a decline in value that is other-than temporary the Company recognizes an impairment loss for the decline in value. i. Investments in associates: Associates are companies in which the Company has significant influence over the financial and operating policies without having control. The investment in associates is accounted for using the equity method of accounting. Under the equity method, the investment in associates is accounted for in the financial statements at cost plus changes in the Group's share of net assets, including other comprehensive income (loss) of the associates. The equity method is applied until the loss of significant influence or classification of the investment as non-current asset held-for-sale. The accounting policy in the financial statements of the associates has been applied consistently and uniformly with the policy applied in the financial statements of the Group. j. Intangibles assets: Intangible assets consist of above-market value of in-place leases that were recorded in connection with the acquisition of the properties. Intangible assets are amortized and accreted using the straight-line method over the term of the related leases. When a lease is terminated early, any remaining unamortized balances under lease intangible assets or liabilities are charged to earnings. k. Derivative instruments: The Company accounts for derivatives and hedging based on ASC No. 815, "Derivatives and Hedging". ASC No. 815 requires the Company to recognize all derivatives at fair value. The accounting for changes in the fair value of a derivative instrument (i.e., gains or losses) depends on whether it has been designated and qualified as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualified as hedging instruments, the Company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. If the derivatives meet the definition of a hedge and are so designated, depending on the nature of the hedge, changes in the fair value of such derivatives will either be offset against the change in fair value of the hedged assets, liabilities, firm commitments through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is recognized in earnings. As of December 31, 2019 and 2018, the Company had outstanding hedging instruments in the amount of $ 68 and $ 206 respectively , which included as of December 31, 2019 in short-term liabilities and as of December 31, 2018 in long-term liabilities, and a $ 458 and $ 313, respectively, which included in long-term Assets. At times, the Company may use derivative instruments to manage exposure to variable interest and currency rate risk. Occasionally, the Company enters into interest and currency rate swaps to manage its exposure to variable interest and currency rate risk and treasury locks to manage the risk of interest and currency rates rising prior to the issuance of debt. The Company generally enters into derivative instruments that qualify as cash flow hedges and it does not enter into derivative instruments for speculative purposes. l. Revenue recognition: The company is a lessor under non-cancellable operating leases and generates revenues from fixed income real-estate according to ASC 842 which derived from its buildings held through its subsidiaries in Switzerland (Rümlang and Geneva), Germany and Miami FL. Rental income includes minimum rents which are recognized on an accrual basis over the terms of the related leases on a straight-line basis. Lease revenue recognition commences when the contract conveys the rights to control the use of the asset to the lessee for a period in exchange to considerations. m. Contingencies: The Company periodically estimates the impact of various conditions, situations and/or circumstances involving uncertain outcomes to its financial condition and operating results. The Company accounts for contingent events as required by ASC 450 "Contingencies". ASC 450 defines a contingency as "an existing condition, situation, or set of circumstances involving uncertainty as to possible gain or loss to an enterprise that will ultimately be resolved when one or more future events occur or fail to occur". Legal proceedings are a form of such contingencies. In accordance with ASC 450, accruals for exposures or contingencies are being provided when the expected outcome is probable. However, it is possible that future results of operations for any particular quarter or annual period could be materially affected by changes in the Company's assumptions, the actual outcome of such proceedings or as a result of the effectiveness of the Company strategies related to these proceedings. n. Income taxes: The Company and its subsidiaries account for income taxes in accordance with ASC Topic 740, "Income Taxes" "ASC 740", prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company and its subsidiaries provide a valuation allowance, if necessary, to reduce deferred tax assets to amounts more likely than not to be realized. ASC 740 clarifies the accounting for uncertainties in income taxes by establishing minimum standards for the recognition and measurement of tax positions taken or expected to be taken in a tax return. Under the requirements of ASC 740, the Company must review all of its tax positions and make a determination as to whether its position is more-likely-than-not to be sustained upon examination by regulatory authorities. If a tax position meets the more-likely–than-not standard, then the related tax benefit is measured based on a cumulative probability analysis of the amount that is more-likely-than-not to be realized upon ultimate settlement or disposition of the underlying issue. The Company policy is to accrue interest and penalties related to unrecognized tax benefits in its tax expenses. The Company believes that its tax positions are all highly certain of being upheld upon examination. As such, as of December 31, 2019 and 2018 the Company has not recorded a liability for uncertain tax positions. o. Concentrations of credit risk: Financial instruments that potentially subject the Company and its subsidiaries to concentrations of credit risk consist principally of cash and cash equivalents, accounts receivables and long-term lease deposits. Cash and cash equivalents are invested in U.S. dollar deposits with major banks in Israel, the United States, Switzerland and Germany. Cash and cash equivalents in the United States may be in excess of insured limits and are not insured in other jurisdictions. The Company maintains cash and cash equivalents with diverse financial institutions and monitors the amount of credit exposure to each financial institution. Accounts receivable includes amounts billed to tenants and accrued expense recoveries due from tenants. The Company makes estimates of un-collectability from its accounts receivable using the specific identification method related to base rents, straight-line rent balances, expense reimbursements and other revenues. The Company also analyzes accounts receivable and historical bad debt levels, tenant credit-worthiness, payment history and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Accounts receivable are written-off when they are deemed to be uncollectible and the Company is no longer actively pursuing collection. The Company's reported net income is directly affected by the management's estimate of the collectability of accounts receivable. p. Earnings (loss) per share: Basic net earnings (losses) per share are computed based on the weighted average number of Ordinary shares outstanding during each year. Diluted net earnings (losses) per share is computed based on the weighted average number of Ordinary shares outstanding during each year, plus dilutive potential Ordinary shares considered outstanding during the year, in accordance with ASC 260, "Earning Per Share". q. Accounting for stock-based compensation: ASC Topic 718 "Compensation - Stock Compensation" "ASC 718", requires companies to estimate the fair value of share-based awards on the date of grant using an option-pricing model. The Company recognizes these compensation costs net of forfeiture rate and recognizes the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of four years. The Company estimates the fair value of stock options granted using the Black-Scholes- Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility and the expected option term. Expected volatility is calculated based upon actual historical stock price movements. The expected term of options granted is based upon historical experience and represents the period of time that options granted are expected to be outstanding. The risk free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. The Company has historically not paid dividends and has no foreseeable plans to pay dividends. During 2019 and 2018 there were no new grants. r. Treasury shares: During the past years, the Company repurchased certain Ordinary shares on the open market and holds such shares as treasury shares. The Company presents the cost to repurchase treasury shares as a reduction from the shareholders' equity. From time to time the Company reissues treasury shares under the stock purchase plan, upon exercise of option and upon vesting of restricted stock units. When treasury stock is reissued, the Company accounts for the re-issuance in accordance with ASC No. 505-30, "Treasury Stock" and charges the excess of the purchase cost, including related stock-based compensation expenses, over the re-issuance price to retained earnings. The purchase cost is calculated based on the specific identification method. In case the purchase cost is lower than the re-issuance price, the Company credits the difference to additional paid-in capital. s. Fair value of financial instruments: The carrying amounts of the Company's financial instruments, including cash and cash equivalents, other accounts receivable, trade payables, other accounts payable, and accrued liabilities, approximate fair value because of their generally short-term maturities. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820 establishes a three-level value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Include other inputs that are directly or indirectly observable in the marketplace. Level 3 - Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Swap instruments are measured at fair value under ASC 820 on a recurring basis as of December 31, 2019 and 2018. t. Comprehensive income: The Company accounts for comprehensive income in accordance with ASC No. 220, "Comprehensive Income". Comprehensive income generally represents all changes in shareholders' equity during the period except those resulting from investments by, or distributions to, shareholders. u. Recently issued and adopted accounting pronouncements: In February 2016, the FASB issued ASU 2016-02, “Leases” ("ASC 842"), on the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also 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 classification. Leases with a term of 12 months or less will be accounted for in a manner similar to the accounting under the prior guidance (ASC 840). The new standard requires lessors to account for leases using an approach that is substantially equivalent to ASC 840 guidance for sales-type leases, direct financing leases and operating leases. The new standard supersedes the previous leases standard, ASC 840, "Leases". The company elected the lessor practical expedient to not separate lease and non-lease components in contract and instead to account for as a single lease component, if certain criteria are met. The Company adopted the new standard as of January 1, 2019, using the modified retrospective approach. Consequently, prior period balances and disclosures have not been restated. The Company have elected to utilize the available package of practical expedients permitted under the transition guidance within the new standard which does not require it to reassess the prior conclusions about lease identification, lease classification and initial direct costs. The Company included in our balance sheet at adoption an operating right-of-use assets, short term operating lease liabilities and long term operating lease liabilities of $ 463, $ 124 and $ 339, respectively. The standard did not materially impact our net earnings and had no material impact on cash flows. For additional information regarding our accounting for leases, please refer to Note 7. New accounting pronouncements not yet effective: In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses on Financial Instruments”, which requires that expected credit losses relating to financial assets measured on an amortized cost basis and available for sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available for sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The new standard will be effective for interim and annual periods beginning after January 1, 2020, and early adoption is permitted. The Company do not expect this standard to have a material effect on our consolidated financial statements.

COMMITMENTS AND CONTINGENT LIABILITIES	NOTE 12:- COMMITMENTS AND CONTINGENT LIABILITIES a. Assets pledged as collateral: As collateral for the Company's loan mortgages, a fixed pledge has been placed on the Company's subsidiaries in Luxemburg shareholders' equity. See Note 10a. b. Israel Innovation Authority commitments: Until the sale of the Video Activity the Company participated in programs sponsored by the Israeli Government and by the European Commission for the support of research and development activities.

As of December 31, 2019, the Company has sufficient provisions to cover the expected outcome of such review process. The provision for the above commitments was recorded under liabilities attributed to discontinued operations as the Company has no further obligation to pay royalties on revenues generated by the Video Activity subsequent to its sale. c.

On October 26, 2014, the Company received a letter on behalf of two purported shareholders (the "Shareholders") demanding the Company to file a derivative claim against its controlling shareholder and directors and officers, according to procedures of the Companies Law and requesting discovery of internal documents. The demand alleges, among other things, breach of fiduciary duties by directors and officers with respect to the approval of the transaction to acquire condominium units in Miami Beach, Florida, (the "Transaction"), in accordance with the Companies Law. The Company presented the Shareholders, at their request, with certain materials in connection with the Transaction for their review. On May 12, 2015 the Company has been served with a motion to approve the filing of a derivative claim against its controlling shareholder, directors and CEO and against certain former controlling shareholder and directors, (the "Motion"). The Claim alleges, among other things, a breach of fiduciary duties by the Company directors, officers and controlling shareholder, and an exploitation of a business opportunity by the Company current and former controlling shareholder with respect to certain private placements of the Company's shares to its controlling shareholder. The Claim further alleges, that such private placements constitute a prohibited distribution as the shares were issued for an unfair consideration. As a result of the above, the Applicants request the Court to allow them to continue with this derivative claim and ultimately to require all the defendants to pay the Company an aggregate amount of approximately $ 41,900, as well as required the Companies shareholder (current and former) to pay to the Company approximately $ 2,800 plus interest (for the exploitation of a business opportunity). The Applicants further require reimbursement of expenses, legal fees and award to the Applicants. On November 8, 2015, The Company has submitted its response to the Motion and Claim together with an expert opinion. The Company has raised several arguments against the Motion including, inter alia, preliminary claims to dismiss the Motion in-limine. On November 13, 2015, the directors, CEO and former directors submitted their response to the Motion. On September 6, 2016, the Applicants submitted to the District Court their answer to the Company's response to the motion to approve the filing of a derivative claim, together with an expert opinion. On October 30, 2016, a pre-trial hearing was held during which the Court gave instruction regarding the scope of disclosure that the Company needs to discover. On March 14, 2017 the Company, the Company's directors, CEO and former directors' submitted an expert opinion as a response to the expert opinion submitted by the Applicants. On May 29, 2017 the Company's controlling shareholder submitted an expert opinion as a response to the expert opinion submitted by the Applicants. The first cross-examination hearing was held on October 31, 2017, and additional hearings were held on November 19, 2017, December 5, 2017, February 25, 2018, October 7, 2018, December 2, 2018 and December 18, 2018. On June 16, 2019, the District Court denied the motion to approve the filing of the derivative claim. On September 22, 2019, the Applicants filled an appeal to the District Court's decision to the Supreme Court. On February 20, 2020, the applicants submitted their written summations and the Company should file its summations by May 30, 2020. The hearing of the Appeal is scheduled to September 23, 2020. At this stage the Company cannot provide an assessment as to the chances of the claim and the exposure to the Company. 2. On March 6, 2019, the Company has notified that Swiss Pro Capital Limited, a company organized under the laws of Switzerland, has filed a legal claim against the Company's subsidiaries, Optibase RE 1 s.a.r.l and Optibase Real Estate Europe SARL. The matter of the claim is an option agreement signed between the parties on March 1, 2010, whereby the plaintiff was given the option for 8 years to purchase 20% of the shares of Optibase RE1, which holds a building in Switzerland, at a price to be calculated on the option exercise date according to a formula set forth in the agreement. In the statement of claim, it is claimed that starting at the end of 2014, the plaintiff approached the Company to check the possibility of exercising the option. Accordingly, the plaintiff requested to get data about the property in order for it to be able to check the updated option price. According to the plaintiff, after it was ignored by the Company, the option price as finally presented by the Company does not reflect the correct option price in accordance with the intent of the parties to the agreement and in accordance with the formula specified therein, and the Company artificially raised the option price. Thus, according to the plaintiff, for the price of the options to be without financial merit, Optibase REE did not draw dividends available for distribution from Optibase RE1. In addition, the Company did not refinance the property, and even imposed excess management expenses and other unnecessary expenses on Optibase RE1. The plaintiff claims that the correct option exercise price, and as it was actually exercised on May 25, 2016, is zero Swiss Francs, and it seeks for the court to issue a declaratory order under which it is entitled to receive 20% of the shares of Optibase RE1 at a price of zero Swiss Francs, and to issue orders to remove the discrimination, including that the Company must pay the plaintiff a sum of 400,000 Swiss Francs. On July 29, 2019 the Companies filed a statement of defence. The Company categorically deny the allegations raised in the statement of claim, and claim that the option price as given over by them reflects what is stated in the option agreement and that, in complete contradiction to the plaintiff's claims, they did not artificially raise the price of the option as alleged. The parties were referred to mediation that ended without reaching a settlement. The court is expected to set a preliminary hearing on the claim. At this stage the Company cannot provide an assessment as to the chances of the claim. 3. On April 16, 2015, the Company's subsidiary Eldista GmbH, filed a claim to the court in Switzerland in an amount of CHF 961,000 due to damages and unpaid amounts from a specific tenant. Shortly thereafter, the tenant filed a counterclaim against Eldista GmbH in an amount of CHF 157,000 for damages allegedly caused to it. The court suggested the parties to transfer to mediation proceedings which failed. The court handed down a partial judgment on 31, October 2016, dismissing Eldista GmbH's claim (though it had not yet examined the issue of the damages). Eldista GmbH filed an appeal against the judgment, but it was dismissed on June 12, 2017. On May 2, 2018, the court ruled that the damages owned to the tenant shall amount to approximately CHF 53,000 plus interest 5% as of June 4, 2014. An appeal has been filed and is currently pending before the supreme court. Should the supreme court confirm the first judgment, Eldista GmbH will most likely have a counterclaim against the former real estate agency that was managing the CTN Complex, although there is also a possibility that a judge would consider that the latter committed no breach or that only a portion of the damage can be recovered by the agency. On October 27, 2019 the judgment which dismissed the apal filed by Eldista. Eldista was therefore ordered to pay the tenant CHF 53,000 plus interest 5% as of June 4, 2014, as well as an amout of CHF 17,000 as a participation for the tenant legal fees. These amounts were paid in Junuary and February 2020. 4. On March 1 2017, the Company's subsidiary Eldista Gmbh, received a notice from its largest tenant in Switzerland, LEM Switzerland SA, or LEM, regarding the deposit of the monthly rent for March 2017 amounting to approximately CHF 279,000 vat inclusive with Banque cantonale de Genève under the control of the Pouvoir judiciaire of the Canton of Geneva, as a preliminary process for filing a claim with the Commission de Conciliation en Matière de Baux et Loyers of the Canton of Geneva, or the Commission. LEM claims that there are serious defects affecting the rented premises, which merit LEM with a reimbursement of approximately CHF 2,400,000 ((excluding VAT) as well as approximately CHF 69,000 as indemnification for consequential damages for the years 2014 and 2015. LEM also reserves its claims regarding damages suffered before year 2014. On April 5, 2017 LEM withdrew the deposit of the monthly rent for March 2017 with Banque cantonale de Genève under the control of the Pouvoir judiciaire of the Canton of Geneva and released the amount to the Company. Thus, paying the full payment of the rent. Based on LEM’s submissions filed during the first hearing before the court, LEM is requesting a 20% rent reduction amounting to a capital amount of CHF 3,094,000 for the period starting from February 1, 2012, until June 30, 2017, with 5% moratory interest per year starting from October 23, 2017, corresponding to approximately CHF 154,000 per year, based on the various defects allegedly affecting the rented premises. In addition, LEM is claiming for related damages an amount of approximately CHF 168,000, subject to amplification, with 5% moratory interest per year starting from October 23, 2017. LEM’s claim for rent reduction was reduced to 10% from July 1, 2017, until repair of the alleged defects or entry into force of the judgment, that is to say a capital amount of approximately CHF 714,000 if considered from July 1, 2017, until December 31, 2019. LEM further demands to be reserved the right to claim the reimbursement of all ancillary costs paid in axcess to Eldista, without however indicating any amount to support its claim. A first hearing took place on June 26, 2018, before the first instance court for lease matters, and a second hearing took place on November 7, 2018. Following an appeal filed by Eldista on September 12, 2019 against a procedural ordinance of the court rendered on August 30, 2019 regarding the non limitation of the scope of the investigation phase contrarily to Eldista's request in this respect to accelerate the duration of the proceedings, followed by an appeal with the Swiss Supreme Court filed on February 21, 2020, a decision (expected to be negative given the restrictive conditions applying for such appeal) is expected from the Swiss Supreme Court for the next weeks. The change of President that took place in August 2019, and the appeals made in September 2019 and February 2020 by Eldista, did not accelerate the starting of the proceedings and would thus postpone the possible risk of Eldista of being condemned to pay LEM the requested amounts. An out-of-court settlement was proposed by LEM’s counsel on May 15, 2019 without prejudice, including the complete withdrawal of LEM’s pending claim in full and final settlement provided that Eldista authorizes LEM to stay in the building after the end of the lease for a determined period starting from 1st April 2020 until December 31, 2021 with a reduced rent of 20% justified by the market conditions that would correspond to a capital amount of CHF 1,000,000 approximately. Eldista made a counterproposal on August 29, 2019 of CHF 346,000 which was refused by LEM on September 9, 2019. LEM made a counterproposal at CHF 700,000 plus the right to vacate the premises without any obligation to reinstate, to which Eldista did not answer to date focusing on the proceedings. For further details regarding new litigation between Eldista and LEM see note 19a. As of December 31, 2019, the Company has sufficient provisions to cover the expected outcome of this claim.

Income Tax Disclosure [Abstract]
TAXES ON INCOME	NOTE 14:- TAXES ON INCOME a. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "TCJA"). The TCJA makes broad and complex changes to the Code. The changes include, but are not limited to: 1. A corporate income federal tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017 ("Rate Reduction"); 2. The transition of U.S international taxation from a worldwide tax system to a territorial system by providing a 100 percent deduction to an eligible U.S. shareholder on foreign sourced dividends received from a foreign subsidiary; 3. A one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017; and 4. Taxation of GILTI earned by foreign subsidiaries beginning after December 31, 2017. The Global Intangible Low-Taxed Icome GILTI tax imposes a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. b. Corporate tax rates: Israeli companies are generally subject to corporate tax on their taxable income. As of 2019 and 2018 the corporate tax rate is 23% (in 2017 and 2016, the corporate tax rate was 24% and 25%, respectively). In December 2016, the Israeli Parliament approved the Economic Efficiency Law (Legislative Amendments for Applying the Economic Policy for the 2017 and 2018 Budget Years), 2016 which reduces the corporate income tax rate to 24% (instead of 25%) effective from January 1, 2017 and to 23% effective from January 1, 2018. Capital gains derived by an Israeli company are subject to the prevailing corporate tax rate. Taxable income of the Company's subsidiary in Luxemburg, Switzerland and the United States may be subject to the following statutory federal (approximate) tax rates: Year ended December 31, 2019 2018 2017 Luxemburg 29 % 29 % 29 % Switzerland 24 % 24 % 24 % United States 21 % 21 % 34 % Germany 16 % 16 % 16 % c. Tax assessments: The Company has final tax assessments in Israel through the tax year 2014. d. Deferred tax assets and liabilities: Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets and liabilities mainly derive from the acquisitions of commercial buildings in Switzerland. The deferred taxes are computed at the average tax rate of 24%, based on the corporate income tax in Switzerland, which is the tax rate that will be in effect when the differences are expected to reverse. Significant components of the Company and its subsidiary deferred tax assets are as follows: December 31, 2019 2018 Deferred tax assets: Net Operating losses and other temporary diffs. $ 28,941 $ 25,892 Lease provision 1,466 1,472 Other 193 196 Deferred tax assets 30,600 27,560 Deferred tax liabilities: Land (5,437 ) (5,362 ) Building (10,020 ) (10,058 ) Other (3,331 ) (2,571 ) Deferred tax liabilities (18,788 ) (17,991 ) Valuation allowance (25,613 ) (23,321 ) Deferred tax liabilities, net $ (13,801 ) $ (13,752 ) e.

Utilization of U.S. net operating losses may be subject to the substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986, and similar state provisions. The annual limitation may result in the expiration of net operating losses before utilization. Based upon the weight of available evidence, which includes the Company's historical operating performance and the recorded cumulative net losses in all prior fiscal periods, the Company has provided a full valuation allowance against it Israeli and U.S deferred tax assets. f.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 19:- SUBSEQUENT EVENTS a. On Junuary 27, 2020, a formal filing of a claim was submitted by LEM against Eldista. LEM is claiming a first extension of its current lease until December 31, 2021, or until September 30, 2022 at the latest. LEM is also claiming a rent reduction of 16.94% (that is a reduction of approximately CHF 40,000 per month) from April 2020 until the end of the extension (the latest term being 30 September 2022) which corresponds to a total amount of CHF 1,189,000. A first conciliation hearing is appointed on April 29, 2020. b. On February 11, 2020 the Company by its wholly owned European subsidiary, Optibase Bavaria GmbH & Co. KG, had entered into a definitive agreement with an unrelated third party buyer, to sell its retail portfolio in Germany comprised of twentyseven (27) separate commercial properties, located in Bavaria, Germany, for an aggregate cash consideration of EUR 35,000,000 (approximately $ 38,900). The closing of the transaction is subject, among other things, to customary conditions, including (i) the waiver of a right of first refusal by the main tenant; and (ii) the waiver by the local municipalities of their right of first refusal on each of the properties. The exercise of the right of first refusal in regard to certain properties, will not affect the closing of the transaction with respect to the other properties. The closing will be conducted in tranches with respect to certain groups of properties and is expected to occur over the course of first and second quarters of 2020. The property net balanc is approximately $ 29,700 (including PPA in amount of $ 157) and presented in the Company's balance sheet as property held for sale. c. In December 2019, a novel strain of coronavirus (COVID-19) was reported in China and has since been reported in other countries. On March 11, 2020 the World Health Organization declared COVID-19 as a global pandemic and recommended containment and mitigation measures worldwide. The current outbreak, including the resulting travel restrictions and quarantines already imposed by several countries, present concerns that may dramatically affect the Company's ability to conduct the Company's business effectively and may affect the Company’s ability to dispose of or liquidate part of its real estate. The Company may suffer decline in rents or an increased incidence of defaults under existing leases and in general declining demand for real estate. If the Company cannot operate the Company's properties so as to meet the Company's financial expectations, the Company's business, financial condition, results of operations, cash flow or the Company's ability to satisfy the Company's debt service obligations may be negatively impacted. At this stage, the Company is unable to assess the scope of the impact on the business and operations and in the event that the economic effect of the outbreak deepens and has a long term effect on the global economy, the Company's business and operations may be adversely effected.

The functional currencies of Optibase's subsidiaries are U.S dollar, CHF and EUR. Assets and liabilities of these subsidiaries are translated at the year-end exchange rates and their statement of operations items are translated using the average exchange rates for all periods presented. The resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income in shareholders' equity.
Principles of consolidation	c. Principles of consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation.
Non-controlling Interests	d. Non-controlling interests: Non-controlling interests generally represent the portion of equity that the Company does not own in the consolidated entities. The Company accounts for and reports its non-controlling interests in accordance with the provisions required under the Consolidation Topic of the FASB ASC 810. Non-controlling interests are separately presented within the equity section of the consolidated balance sheets. The amounts of consolidated net earnings attributable to the Company and to the non-controlling interests are presented on the consolidated statement of operations.
Cash equivalents	e. Cash equivalents: Cash equivalents include short-term, highly liquid investments that are readily convertible to cash, with original maturities of three months or less at the date acquired.
Property	f. Property: Real estate properties are stated at cost net of accumulated depreciation. Costs include those related to acquisition, including building improvements. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: Years Building 25 - 63 Buildings' improvements 5 - 20 Condominium units 30
Impairment of long-lived assets, right-of-use assets and intangible assets	g. Impairment of long-lived assets, right-of-use assets and intangible assets: The Group's long-lived assets (assets group) to be held or used, including property and equipment, right of use assets and intangible assets subject to amortization are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment" and ASC 350, “Intangibles - Goodwill and other”, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In assessing the recoverability of long-lived assets, the Company makes judgments regarding whether impairment indicators exist based on legal factors, market conditions and operating performances of assets or asset groups. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured by the carrying amount of the assets exceeds the fair value of the assets. The Company reviews assets on a component-level basis, which is the lowest level of assets for which there are identifiable cash flows that can be distinguished operationally and for financial reporting purposes. The carrying amount of the asset was compared with the related expected undiscounted future cash flows to be generated by those assets over the estimated remaining useful life of the primary asset. In cases where the expected undiscounted future cash flows were less than the carrying amounts of the assets, those assets were considered impaired and written down to their fair values. Fair value was established based on discounted cash flows. As of December 31, 2019 and 2018, no impairment losses have been identified.
Investments in companies	h. Investments in companies: Investments in non-marketable equity securities of companies in which the Company does not have control or the ability to exercise significant influence over their operation and financial policies are recorded at cost. The management evaluates investments in non-marketable equity securities as evidence of other-than temporary declines in value. When relevant factors indicate a decline in value that is other-than temporary the Company recognizes an impairment loss for the decline in value.
Investments in associates	i. Investments in associates: Associates are companies in which the Company has significant influence over the financial and operating policies without having control. The investment in associates is accounted for using the equity method of accounting. Under the equity method, the investment in associates is accounted for in the financial statements at cost plus changes in the Group's share of net assets, including other comprehensive income (loss) of the associates. The equity method is applied until the loss of significant influence or classification of the investment as non-current asset held-for-sale. The accounting policy in the financial statements of the associates has been applied consistently and uniformly with the policy applied in the financial statements of the Group.
Intangibles assets	j. Intangibles assets: Intangible assets consist of above-market value of in-place leases that were recorded in connection with the acquisition of the properties. Intangible assets are amortized and accreted using the straight-line method over the term of the related leases. When a lease is terminated early, any remaining unamortized balances under lease intangible assets or liabilities are charged to earnings.
Derivative instruments	k. Derivative instruments: The Company accounts for derivatives and hedging based on ASC No. 815, "Derivatives and Hedging". ASC No. 815 requires the Company to recognize all derivatives at fair value. The accounting for changes in the fair value of a derivative instrument (i.e., gains or losses) depends on whether it has been designated and qualified as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualified as hedging instruments, the Company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. If the derivatives meet the definition of a hedge and are so designated, depending on the nature of the hedge, changes in the fair value of such derivatives will either be offset against the change in fair value of the hedged assets, liabilities, firm commitments through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value is recognized in earnings. As of December 31, 2019 and 2018, the Company had outstanding hedging instruments in the amount of $ 68 and $ 206 respectively , which included as of December 31, 2019 in short-term liabilities and as of December 31, 2018 in long-term liabilities, and a $ 458 and $ 313, respectively, which included in long-term Assets. At times, the Company may use derivative instruments to manage exposure to variable interest and currency rate risk. Occasionally, the Company enters into interest and currency rate swaps to manage its exposure to variable interest and currency rate risk and treasury locks to manage the risk of interest and currency rates rising prior to the issuance of debt. The Company generally enters into derivative instruments that qualify as cash flow hedges and it does not enter into derivative instruments for speculative purposes.
Revenue recognition	l. Revenue recognition: The company is a lessor under non-cancellable operating leases and generates revenues from fixed income real-estate according to ASC 842 which derived from its buildings held through its subsidiaries in Switzerland (Rümlang and Geneva), Germany and Miami FL. Rental income includes minimum rents which are recognized on an accrual basis over the terms of the related leases on a straight-line basis. Lease revenue recognition commences when the contract conveys the rights to control the use of the asset to the lessee for a period in exchange to considerations.
Contingencies	m. Contingencies: The Company periodically estimates the impact of various conditions, situations and/or circumstances involving uncertain outcomes to its financial condition and operating results. The Company accounts for contingent events as required by ASC 450 "Contingencies". ASC 450 defines a contingency as "an existing condition, situation, or set of circumstances involving uncertainty as to possible gain or loss to an enterprise that will ultimately be resolved when one or more future events occur or fail to occur". Legal proceedings are a form of such contingencies. In accordance with ASC 450, accruals for exposures or contingencies are being provided when the expected outcome is probable. However, it is possible that future results of operations for any particular quarter or annual period could be materially affected by changes in the Company's assumptions, the actual outcome of such proceedings or as a result of the effectiveness of the Company strategies related to these proceedings.
Income taxes	n. Income taxes: The Company and its subsidiaries account for income taxes in accordance with ASC Topic 740, "Income Taxes" "ASC 740", prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company and its subsidiaries provide a valuation allowance, if necessary, to reduce deferred tax assets to amounts more likely than not to be realized. ASC 740 clarifies the accounting for uncertainties in income taxes by establishing minimum standards for the recognition and measurement of tax positions taken or expected to be taken in a tax return. Under the requirements of ASC 740, the Company must review all of its tax positions and make a determination as to whether its position is more-likely-than-not to be sustained upon examination by regulatory authorities. If a tax position meets the more-likely–than-not standard, then the related tax benefit is measured based on a cumulative probability analysis of the amount that is more-likely-than-not to be realized upon ultimate settlement or disposition of the underlying issue. The Company policy is to accrue interest and penalties related to unrecognized tax benefits in its tax expenses. The Company believes that its tax positions are all highly certain of being upheld upon examination. As such, as of December 31, 2019 and 2018 the Company has not recorded a liability for uncertain tax positions.
Concentrations of credit risk	o. Concentrations of credit risk: Financial instruments that potentially subject the Company and its subsidiaries to concentrations of credit risk consist principally of cash and cash equivalents, accounts receivables and long-term lease deposits. Cash and cash equivalents are invested in U.S. dollar deposits with major banks in Israel, the United States, Switzerland and Germany. Cash and cash equivalents in the United States may be in excess of insured limits and are not insured in other jurisdictions. The Company maintains cash and cash equivalents with diverse financial institutions and monitors the amount of credit exposure to each financial institution. Accounts receivable includes amounts billed to tenants and accrued expense recoveries due from tenants. The Company makes estimates of un-collectability from its accounts receivable using the specific identification method related to base rents, straight-line rent balances, expense reimbursements and other revenues. The Company also analyzes accounts receivable and historical bad debt levels, tenant credit-worthiness, payment history and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Accounts receivable are written-off when they are deemed to be uncollectible and the Company is no longer actively pursuing collection. The Company's reported net income is directly affected by the management's estimate of the collectability of accounts receivable.
Earnings (loss) per share	p. Earnings (loss) per share: Basic net earnings (losses) per share are computed based on the weighted average number of Ordinary shares outstanding during each year. Diluted net earnings (losses) per share is computed based on the weighted average number of Ordinary shares outstanding during each year, plus dilutive potential Ordinary shares considered outstanding during the year, in accordance with ASC 260, "Earning Per Share".
Accounting for stock-based compensation	q. Accounting for stock-based compensation: ASC Topic 718 "Compensation - Stock Compensation" "ASC 718", requires companies to estimate the fair value of share-based awards on the date of grant using an option-pricing model. The Company recognizes these compensation costs net of forfeiture rate and recognizes the compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of four years. The Company estimates the fair value of stock options granted using the Black-Scholes- Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility and the expected option term. Expected volatility is calculated based upon actual historical stock price movements. The expected term of options granted is based upon historical experience and represents the period of time that options granted are expected to be outstanding. The risk free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. The Company has historically not paid dividends and has no foreseeable plans to pay dividends. During 2019 and 2018 there were no new grants.
Treasury Shares	r. Treasury shares: During the past years, the Company repurchased certain Ordinary shares on the open market and holds such shares as treasury shares. The Company presents the cost to repurchase treasury shares as a reduction from the shareholders' equity. From time to time the Company reissues treasury shares under the stock purchase plan, upon exercise of option and upon vesting of restricted stock units. When treasury stock is reissued, the Company accounts for the re-issuance in accordance with ASC No. 505-30, "Treasury Stock" and charges the excess of the purchase cost, including related stock-based compensation expenses, over the re-issuance price to retained earnings. The purchase cost is calculated based on the specific identification method. In case the purchase cost is lower than the re-issuance price, the Company credits the difference to additional paid-in capital.
Fair value of financial instruments	s. Fair value of financial instruments: The carrying amounts of the Company's financial instruments, including cash and cash equivalents, other accounts receivable, trade payables, other accounts payable, and accrued liabilities, approximate fair value because of their generally short-term maturities. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820 establishes a three-level value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Include other inputs that are directly or indirectly observable in the marketplace. Level 3 - Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Swap instruments are measured at fair value under ASC 820 on a recurring basis as of December 31, 2019 and 2018.
Comprehensive income	t. Comprehensive income: The Company accounts for comprehensive income in accordance with ASC No. 220, "Comprehensive Income". Comprehensive income generally represents all changes in shareholders' equity during the period except those resulting from investments by, or distributions to, shareholders.
Recently issued and adopted accounting pronouncements	u. Recently issued and adopted accounting pronouncements: In February 2016, the FASB issued ASU 2016-02, “Leases” ("ASC 842"), on the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also 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 classification. Leases with a term of 12 months or less will be accounted for in a manner similar to the accounting under the prior guidance (ASC 840). The new standard requires lessors to account for leases using an approach that is substantially equivalent to ASC 840 guidance for sales-type leases, direct financing leases and operating leases. The new standard supersedes the previous leases standard, ASC 840, "Leases". The company elected the lessor practical expedient to not separate lease and non-lease components in contract and instead to account for as a single lease component, if certain criteria are met. The Company adopted the new standard as of January 1, 2019, using the modified retrospective approach. Consequently, prior period balances and disclosures have not been restated. The Company have elected to utilize the available package of practical expedients permitted under the transition guidance within the new standard which does not require it to reassess the prior conclusions about lease identification, lease classification and initial direct costs. The Company included in our balance sheet at adoption an operating right-of-use assets, short term operating lease liabilities and long term operating lease liabilities of $ 463, $ 124 and $ 339, respectively. The standard did not materially impact our net earnings and had no material impact on cash flows. For additional information regarding our accounting for leases, please refer to Note 7. New accounting pronouncements not yet effective: In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses on Financial Instruments”, which requires that expected credit losses relating to financial assets measured on an amortized cost basis and available for sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available for sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The new standard will be effective for interim and annual periods beginning after January 1, 2020, and early adoption is permitted. The Company do not expect this standard to have a material effect on our consolidated financial statements.
