GENERAL [Abstract]	'
GENERAL	'
	NOTE 1:-	GENERAL
		a.	Optibase Ltd. ("the Company") was incorporated and commenced operations in 1990.
			During 2009 the Company had entered into the fixed-income real estate sector after an acquisition of a commercial building in Switzerland.
	Until the sale of its video solutions business to VITEC Multimedia ("Vitec") in July 2010 (See 1c below), the Company and its U.S subsidiary, Optibase Inc., provided equipment for a wide range of professional video applications in the Broadband IPTV, Broadcast, Government, Enterprise and Post-production markets . (collectively: the Video Activity). Following the sale of the Video Activity, the Company's only operation is the fixed-income real-estate.
	As of December 31, 2013, the Company manages its activity through three active subsidiaries: Optibase Real Estate Europe SARL ("Optibase SARL") in Luxembourg which was incorporated in October 2009, Optibase Inc. in the United States which was incorporated in 1991 ("Optibase Inc.") and OPCTN SA, a Luxembourg company owned 51% by the Company which was incorporated in February 2011 ("Subsidiaries"), (collectively: "the Group").
		b.	Acquisitions and investments in associates:
		1	Centre des Technologies Nouvelles in Geneva, Switzerlan:
	On March 2, 2011 the Company acquired through a newly established subsidiary an office building complex in Geneva, Switzerland known as Centre des Technologies Nouvelles (CTN) (the "Property"). The acquisition was undertaken by OPCTN S.A., a Luxembourg company owned 51% by Optibase and 49% by The Phoenix Insurance Company Ltd and The Phoenix Comprehensive Pension (collectively, "The Phoenix"). OPCTN S.A. undertook the transaction by acquiring all of the ownership interest in the Property owner Eldista GmbH, a Swiss Company ("Eldista").
	CTN is a six-building complex located in the Plan-Les-Ouates business park in the outskirts of Geneva. The complex includes approximately 35,000 square meters (approximately 377,000 square feet) of primarily space and is a center for advanced industries including biotech electronic and information technology industries.
	The total net purchase price for the Eldista shares was CHF 37,720 (representing $ 40,559 - as of the purchase date), subject to a post-closing price adjustment to reflect Eldista's assets and liabilities as of the closing date.
	On the date of the agreement, the Company paid to Apollo CTN S.A.R.L (the "Seller"), CHF 37,420 and additional CHF 300 as post-closing price adjustment (approximately $ 40,234 and $ 319, respectively as of the purchase date).
	The acquisition of the property through the acquisition of Eldista was accounted for by the Company as a business combination in accordance with ASC 805 "Business Combination". The acquired activities and assets of Eldista constitute a business as they consist of inputs and processes applied to those inputs that have the ability to create outputs.
	The results of operations of the acquired property are included in the Company's financial statements from the date the acquisition has been completed.
	The total purchase price was allocated as follows:
			USD
	Cash paid for Eldista shares		$	40,559
	Assets and liabilities acquired:
	Land			23,654
	Building			137,797
	Swap instrument			(392	)

	Lease provision			(7,311	)
	In-place leases, net			1,124
	Deferred tax liabilities			(15,282	)
	Other current net assets			(155	)
	Gain from a bargain purchase			(4,412	)
	Total purchase price			40,559
	Less:
	Purchase price paid by non-controlling interests			(19,875	)
	Net purchase price		$	20,684
	The bargain purchase gain was recorded since the total acquisition date fair value of the identifiable net assets acquired exceeded the total purchase price.
	Accordingly, the Company recorded the bargain purchase gain as other income in the amount of $ 4,412 in the consolidated statement of operations for the year ended December 31, 2011.

		3	Texas Shopping Centers Portfolio:
	On December 31, 2012, the Company through its subsidiary Optibase Inc. acquired approximately 4% beneficial interest in a portfolio of shopping centers located in Texas.
	The shopping centers portfolio includes more than two million square feet of leasable area and is located in Houston, Dallas, and San Antonio areas of Texas. The purchase price for the transaction was approximately $ 4,000 in cash. The transaction was based on a portfolio valuation of approximately $ 342,000 including existing nonrecourse mortgage financing in the principal amount of approximately $ 252,000. The primary mortgage loan has a fixed interest rate of 5.73% and matures in April 2016.
	Optibase Inc., undertook this investment by making a $1,000 capital contribution as an approximately 16.5% limited partner in Global Texas, LP a Florida limited partnership that is a limited partner in Global Texas Portfolio, LP, a Delaware limited partnership.  Global Texas Portfolio, LP acquired 49% of the beneficial interests in the shopping center portfolio.
	In connection with the transaction, Optibase Inc., became an owner of approximately 16.5% of the partnership interests in Global Texas Lender, LP a Florida limited partnership and made a $3,000 capital contribution to Global Texas Lender, LP.  Global Texas Lender, LP provided a loan to Global Texas Portfolio, LP, bearing interest at 11% per annum, to finance a portion of the purchase price paid by Global Texas Portfolio, LP to acquire its 49% beneficial interest in the shopping center portfolio.
		4	Luxury Suite Condominium Miami, Florida:
	On April 9, 2013 and on August 22, 2013, the Company through its subsidiary Optibase Inc. acquired two luxury condominium penthouses located in the Marquis Residence in Miami and one condominium penthouse located in the Ocean One condominium in Sunny Isles Beach in Miami Beach, Florida in a cash consideration for a purchase price of approximately $4,800.
		5	Condominium Units in Miami Beach, Florida:
	On December 31, 2013, following the approval of the Company's audit committee, board of directors and the Company's shareholders, the Company, through its subsidiary Optibase Inc., completed the purchase of 12 residential units in the Flamingo South Beach One Condominium and the Continuum on South Beach Condominium, both located in Miami Beach, Florida from two private companies indirectly controlled by the Company's controlling shareholder (the "seller") for an aggregate net consideration of $7,153 following the off set of rental income of one unit for a period of 3 years to the seller, representing the fair value of  1.31 million new ordinary shares of the Company issued to the seller as of the closing date.
		c.	Sale of the Video Activity (Discontinued operations):
			On March 16, 2010, the Company and its subsidiary, Optibase Inc., entered into an asset purchase agreement (the "Agreement") with Optibase Technologies Ltd. and Stradis Inc., wholly owned subsidiaries of  S.A. Vitec (also known as Vitec Multimedia) (S.A. Vitec, Optibase Technologies Ltd. and Stradis Inc., collectively "Vitec") pursuant to which the Company sold to Vitec all of the assets and liabilities related to the Company's Video Solutions Business (the "Video Activity") for an aggregate consideration of $ 8,000, subject to certain price adjustments and an earn-out mechanism pursuant to which 45% of Vitec's revenues  deriving from the Video Activity exceeding $ 14,000 in the year following the closing of the transaction, will be paid to the Company. Closing of the transaction occurred on July 1, 2010. In the year following the closing, the Company did not achieve the earn-out target and no additional consideration was received by the Company.
	Under the Agreement, the Company and Vitec agreed on a price adjustment mechanism to the initial consideration, upon which, Vitec shall add or subtract to the consideration an amount equal to accounts receivable, net plus other receivables and prepaid expenses minus accounts payable and other payables, all as of the Closing date (the "Adjustment Amount"), whereby the Adjustment Amount as calculated by the Company would be deposited by Vitec in escrow within five days from the closing date, to be released over a period of 12 months as Vitec collects amounts owed to the Company from customers.
	Vitec has refrained from depositing any amount in escrow. This led to a dispute between the parties. For further details see Note 9e (1).
	The results of operations of the Video Activity for the years ended December 31, 2011, 2012 and 2013 were reported separately and retroactively as discontinued operations in the consolidated statements of operations. The result of operations for the year ended December 31, 2011 was a net loss in the amount of $ 51 while during the years 2012 and 2013 the Company does not have any result of operations of the video activity.

SIGNIFICANT 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 revenue and expenses during the reporting period. Actual results could differ from those estimates.
		b.	Functional currency, presentation currency and foreign currency:
			The functional currency of the Company is the U.S Dollar.
			The functional currencies of Optibase's subsidiaries are CHF and U.S dollar. The Company has elected to use U.S dollar as its reporting currency for all years presented.
			While the functional currency of the Company's subsidiaries in the United States is the U.S dollars, the functional currency of the subsidiaries in Switzerland is their lead currency, i.e. CHF. Since the Company's functional and reporting currency is the USD, the financial statements of Optibase Real Estate SARL and OPCTN S.A. whose functional currency has been determined to be CHF have been translated into U.S. dollars.  Assets and liabilities of these subsidiaries are translated at the year-end exchange rates and their statement of operations items are translated using the actual exchange rates at the dates on which those items are recognized. Such 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 those entities that it consolidates. 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 income.
		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 and equipment:
			Real estate and equipment 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 and buildings' improvements			20-63
		g.	Long-lived assets including intangible assets:
			The Company and its subsidiaries long-lived assets are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment", whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be 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 to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
			The Company reviewed 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 group 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 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, 2012 and 2013, 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.
			Management evaluates investments in non-marketable equity securities for 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. As for impairment charges recorded during 2012 see Note 6a.
		i.	Investments in associates:
			Associates are companies in which the Group 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.	Goodwill and bargain purchase gain:
	Goodwill reflects the excess of the fair value of the acquired business over the fair value of net identifiable assets acquired in various business acquisitions. The Company accounts for goodwill in accordance with the Intangibles - Goodwill and Other Topic of the FASB ASC 350.
	A bargain purchase gain in the Eldista acquisition, represents the excess of 100% of the recognized bases of identifiable assets acquired, net of assumed liabilities, over the aggregate of the acquisition-date fair values of (1) the acquirer's interest in the acquiree, (2) noncontrolling interests in the acquiree and (3) any equity interest held in the acquiree by the acquirer immediately before the acquisition date.
	With respect to bargain purchase, the Company recognized a gain in the amount of $ 4,412 a corresponding deduction from net income attributable to non-controlling interest in the amount of $ 2,162 in the consolidated statement of operations for the year ended December 31, 2011 (See note 1.b(1)).
		k.	Intangibles assets:
	Intangible assets consist of in-place lease values, tenant origination costs and above-market rents 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.
		l.	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 on the balance sheet at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify 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, or 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, 2012 and 2013, the Company had no outstanding hedging instruments. At times, it may use derivative instruments to manage exposure to variable interest rate risk. From time to time, the Company enters into interest rate swaps to manage its exposure to variable interest rate risk and treasury locks to manage the risk of interest 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.
		m.	Business Combinations:
			The Company allocated the purchase price of acquired properties to land, building, intangible assets and other liabilities in accordance with the Business Combinations Topic of the FASB ASC 805-10.  The Company allocated the initial purchase price of assets acquired (net tangible and identifiable intangible assets) and liabilities assumed based on their relative fair values at the date of acquisition. There are two categories of intangible assets to be considered:
			(1) in-place leases; (2) above and below-market value of in-place leases. The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to depreciation expense over the estimated remaining term of the respective leases. The value of above-market and below-market in-place leases is amortized to rental revenue over the estimated remaining term of the leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off. Other than as discussed above, the Company has determined that our real estate properties do not have any other significant identifiable intangibles. The results of operations of acquired properties are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with property acquisitions are included in other assets and other liabilities in our consolidated balance sheets.
		n.	Revenue recognition:
			The Company generates revenues from fixed income real-estate derived from its buildings held through its subsidiaries in Switzerland (Rümlang and Geneva) 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 lessee is given possession of the leased space and there are no contingencies offsetting the lessee's obligation to pay rent.
		o.	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. It is possible, however, 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.
		p.	Income taxes:
			The Company and its subsidiaries account for income taxes in accordance with ASC Topic 740, "Income Taxes" ("ASC 740"),  which 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 financial expenses.
		q.	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 and Switzerland. 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 the uncollectability of its accounts receivable using the specific identification method related to base rents, straight-line rent balances, expense reimbursements and other revenues. It 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 management's estimate of the collectability of accounts receivable.
		r.	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".
		s.	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 a 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. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
	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.
	The fair value was estimated at the date of grant using the following weighted average assumptions for the Black-Scholes model for the year ended December 31, 2011. During 2012 and 2013 there were no grants.
			December 31,
			2011
	Dividend yield			0	%
	Volatility			67	%
Risk free interest			0.9%-1.7	%
Expected term (years)			4.75
	t.	Treasury Shares:
		During the past years, the Company repurchased certain of its 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 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.
	u.	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-tier 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 instrument (see note 1b(1)) are measured at fair value under ASC 820 on a recurring basis as of December 31,2012 and 2013.
	v.	Comprehensive income:
In June 2011, the FASB issued ASU 2011-05 Presentation of Comprehensive Income, codified in ASC 220 "Comprehensive Income". The guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The guidance also eliminates the option to present the components of other comprehensive income as part of the statement of equity. The Company adopted the new guidance commencing January 1, 2012.  The Company chose to present the Comprehensive Income in two separate but consecutive statements.
	w.	Accounting Pronouncements
In July 2013, the FASB issued ASU 2013-11, Topic 740, " Income Taxes", which limits the situations in which unrecognized tax benefits are offset against a deferred tax asset for a net operating loss carry-forward, similar tax loss or tax credit carry forward. ASU 2013-11 is effective for reporting periods beginning after December 15, 2013. We intend to adopt this standard in 2014 and do not expect the adoption will have a material impact on our consolidated results of operations or financial condition.

LONG TERM LOANS	'
	NOTE 8:-	LONG TERM LOANS
		a.	On October 29, 2009, Optibase SARL received a mortgage loan ("the Loan") from a financial institution in Switzerland, in the amount of CHF 18,800 for the purpose of purchasing the real estate property located in Rümlang, Switzerland ("the Property"). The loan bears a variable interest rate based on current money and capital markets in Switzerland plus the bank's customary margins (0.8%). The financial institution may increase margin at any time if creditworthiness of the borrower or quality of the property is impaired. Principal and interest of the loan are payable quarterly. The mortgage loan may be repaid at any time with a three months prior written notice by the Company. The mortgage loan is governed by the laws of Switzerland and bears other terms and conditions customary for that type of mortgage loans. The Company pledged to the bank the property and all accounts and assets of the Company's subsidiary which are deposited with the bank against the loan received. The Company is required to meet certain covenants under this mortgage loan. As of December 31, 2013, the Company met these covenants.
			Maturities of the loan by years are as follows:
	Year ended December 31,
	2014 (current maturity)		$	422
	Long-term portion:
	2015			422
	2016			422

		b.	On September, 2010, Eldista was granted a mortgage loan from a financial institution in Switzerland, in the amount of CHF 85,250 for the purpose of purchasing its real estate property located in Geneva, Switzerland. The Company pledged to the bank the property and all accounts and assets of the Company's subsidiary which are deposited with the bank against the loan received.
	On October 2011, OPCTN and Eldista entered into a CHF 100,000 bank loan refinancing with Credit Suisse for the above mentioned loan. Under the new financing agreement, Credit Suisse provided a new loan to OPCTN and Eldista which replaced the mortgage loan that Credit Suisse provided to Eldista. The combined interest rate of the new loans is 0.83% compared with 1.8% that Credit Suisse charged on the previous mortgage loan. The loans are repaid at a rate of CHF 2,000 per year and are secured by a first mortgage over the property and by a pledge of Eldista's shares.
	The modification of the loan was accounted for by the Company in accordance with ASC 470-50 "Debtor's Accounting for a Modification or Exchange of Debt Instruments". The new debt instrument was initially recorded at fair value and that amount was used to determine the debt extinguishment gain or loss to be recognized and the effective rate of the new instrument.
	As a result of the refinancing of the loan, the Company recorded during 2011 financial expense in the amount of $ 400 (representing CHF 375).
	Maturities of the loan by years are as follows:
	Year ended December 31,
	2014 (current maturity)		$	2,247
	Long-term portion:
	2015			2,247

	NOTE 9:-	COMMITMENTS AND CONTINGENT LIABILITIES
		a.	Lease commitments:
	The Company and its subsidiaries facilities and motor vehicles are leased under several operating lease agreements for periods ending in 2015.
	Future minimum lease commitments under non-cancelable operating leases are as follows:
	Year ended December 31
	2014			56
	2015			47
			$	103
		b.	Guarantees:
	As of December 31, 2013, the Company has obtained bank guarantees in the amount of $ 144.
		c.	Assets pledged as collateral:
	As collateral for the Company's lines of credit and bank guarantees, a fixed charge has been placed on the Company's property and equipment, shareholders' equity, a floating charge (security interest in assets of the Company as they exist from time to time) has been placed on all the other assets of the Company and a specific charge has been placed on the Company's bank deposit as described in Notes 8a and 8b.
		d.	Office of the Chief Scientist and European Commission 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.
	The Company was obligated to pay royalties to the Office of the Chief Scientist ("OCS"), amounting to 3%-3.5% of the sales of the products and other related revenues generated from such projects, up to 100% of the grants received, linked to the U.S. dollar and for grants received after January 1, 1999 also bearing interest at the rate of LIBOR. The obligation to pay these royalties is contingent on actual sales of the products and in the absence of such sales, no payment is required. The Company is currently undergoing an audit by the OCS for royalties paid before the sale of our Video business. As of December 31, 2013, the Company believes it has sufficient provisions to cover the 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.
	Through the sale of the Video Activity, the Company has paid or accrued royalties to the OCS in the amount of $ 4,308, and had an outstanding contingent obligation to pay royalties in the amount of approximately $ 4,248 plus interest.
	In addition, during 2010 and 2011 the Company was audited by the European Commission for grants received under 3 FP6 contracts. As results of the audit findings implementation the Company paid during 2012 an amount of $ 430 which settled and closed the financial audit.
		e.	Legal claim and  contingent liabilities:
	In connection with the sale of Video Activity (as further described in Note 1c) and as part of a dispute arose between Vitec and us, since October, 2010 Vitec and the Company have filed several and separate motions with the Tel-Aviv District Court, seeking, inter alia, fixed and temporary injunctions. The motions filed by both parties have been dismissed by the court and were transferred to arbitration proceedings, which were undergoing during the past three years and until recently.
	On July 30, 2013, the final decision of the arbitrator regarding the arbitration proceedings against Vitec (the "Arbitration Award") was submitted to the parties. The arbitrator accepted the majority of the Company's claims whilst most of Vitec's claims were rejected. In its entirely, the Arbitration Award mentions that the Company acted in the ordinary course of business and Vitec's claims regarding injury to reputation, loss of profits and loss of business opportunities, which constituted a major part of its claim, were totally rejected.
	The arbitrator did award Vitec a total sum of $442. Regarding the costs of the arbitration and lawyers' fees, the Arbitrator awarded Vitec a total sum of $69 considering the fact that only a small portion of the claimed sum was granted to Vitec.
	After the Arbitration Award was given, the Company has made its efforts to execute the Arbitration Award with no further delay, in order to comply with the Arbitrator's decision and to avoid paying unnecessary interests. The Company didn't come to any understating with Vitec regarding the above. Hence, on September 1, 2013, the Company submitted with the Tel-Aviv District Court a motion requesting the confirmation and validation of the Arbitration Award.
	On September 17, 2013, Vitec responded to the Company's motion by submitting a motion of its own, asking the Court to nullify or complete some parts of the Arbitration Award, or alternatively ask the arbitrator to do so, mainly regarding sums received by the Company after the closing of the transaction. Vitec claimed that the Arbitration Award did not include final rulings regarding such sums. Vitec also claimed that the arbitrator has made a calculating mistake in favor of the Company, in the amount of $400 which should be paid to Vitec.
	On February 27, 2014, the Court gave its final ruling. The Court rejected all of Vitec's claims, dismissed its motion to nullify the Arbitration Award and confirmed and validated the Arbitration Award in its entirely. The Court also ruled that Vitec will bear the legal expenses of this proceeding including the costs of the translation of the Arbitration Award.

SIGNIFICANT ACCOUNTING POLICIES (Policy)	12 Months Ended
	Dec. 31, 2013
SIGNIFICANT ACCOUNTING POLICIES [Abstract]	'
Basis of presentation of the financial statements	'
		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 revenue and expenses during the reporting period. Actual results could differ from those estimates.
Functional currency, presentation currency and foreign currency	'
	Functional currency, presentation currency and foreign currency:
	The functional currency of the Company is the U.S Dollar.
	The functional currencies of Optibase's subsidiaries are CHF and U.S dollar. The Company has elected to use U.S dollar as its reporting currency for all years presented.
			While the functional currency of the Company's subsidiaries in the United States is the U.S dollars, the functional currency of the subsidiaries in Switzerland is their lead currency, i.e. CHF. Since the Company's functional and reporting currency is the USD, the financial statements of Optibase Real Estate SARL and OPCTN S.A. whose functional currency has been determined to be CHF have been translated into U.S. dollars.  Assets and liabilities of these subsidiaries are translated at the year-end exchange rates and their statement of operations items are translated using the actual exchange rates at the dates on which those items are recognized. Such translation adjustments are recorded as a separate component of accumulated other comprehensive income in shareholders' equity.
Principles of consolidation	'
	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	'
	Non-controlling Interests:
			Non-controlling interests generally represent the portion of equity that the Company does not own in those entities that it consolidates. 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 income.
Cash equivalents	'
	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 and equipment	'
	Property and equipment:
			Real estate and equipment 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 and buildings' improvements			20-63
Long-lived assets including intangible assets	'
	Long-lived assets including intangible assets:
			The Company and its subsidiaries long-lived assets are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment", whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be 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 to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
			The Company reviewed 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 group 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 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, 2012 and 2013, no impairment losses have been identified.
Investments in companies	'
	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.
	Management evaluates investments in non-marketable equity securities for 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. As for impairment charges recorded during 2012 see Note 6a.
Investments in associates	'
	Investments in associates:
	Associates are companies in which the Group 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.
Goodwill and bargain purchase gain	'
	Goodwill and bargain purchase gain:
	Goodwill reflects the excess of the fair value of the acquired business over the fair value of net identifiable assets acquired in various business acquisitions. The Company accounts for goodwill in accordance with the Intangibles - Goodwill and Other Topic of the FASB ASC 350.
	A bargain purchase gain in the Eldista acquisition, represents the excess of 100% of the recognized bases of identifiable assets acquired, net of assumed liabilities, over the aggregate of the acquisition-date fair values of (1) the acquirer's interest in the acquiree, (2) noncontrolling interests in the acquiree and (3) any equity interest held in the acquiree by the acquirer immediately before the acquisition date.
	With respect to bargain purchase, the Company recognized a gain in the amount of $ 4,412 a corresponding deduction from net income attributable to non-controlling interest in the amount of $ 2,162 in the consolidated statement of operations for the year ended December 31, 2011 (See note 1.b(1)).
Intangible assets	'
	Intangibles assets:
	Intangible assets consist of in-place lease values, tenant origination costs and above-market rents 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	'
	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 on the balance sheet at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify 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, or 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, 2012 and 2013, the Company had no outstanding hedging instruments. At times, it may use derivative instruments to manage exposure to variable interest rate risk. From time to time, the Company enters into interest rate swaps to manage its exposure to variable interest rate risk and treasury locks to manage the risk of interest 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.
Business Combinations	'
	Business Combinations:
	The Company allocated the purchase price of acquired properties to land, building, intangible assets and other liabilities in accordance with the Business Combinations Topic of the FASB ASC 805-10.  The Company allocated the initial purchase price of assets acquired (net tangible and identifiable intangible assets) and liabilities assumed based on their relative fair values at the date of acquisition. There are two categories of intangible assets to be considered:
	(1) in-place leases; (2) above and below-market value of in-place leases. The aggregate value of other acquired intangible assets, consisting of in-place leases, is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates over (ii) the estimated fair value of the property as-if-vacant, determined as set forth above. The value of in-place leases exclusive of the value of above-market and below-market in-place leases is amortized to depreciation expense over the estimated remaining term of the respective leases. The value of above-market and below-market in-place leases is amortized to rental revenue over the estimated remaining term of the leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be written off. Other than as discussed above, the Company has determined that our real estate properties do not have any other significant identifiable intangibles. The results of operations of acquired properties are included in our financial statements as of the dates they are acquired. The intangible assets and liabilities associated with property acquisitions are included in other assets and other liabilities in our consolidated balance sheets.
Revenue recognition	'
	Revenue recognition:
	The Company generates revenues from fixed income real-estate derived from its buildings held through its subsidiaries in Switzerland (Rümlang and Geneva) 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 lessee is given possession of the leased space and there are no contingencies offsetting the lessee's obligation to pay rent.
Contingencies	'
	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. It is possible, however, 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	'
	Income taxes:
	The Company and its subsidiaries account for income taxes in accordance with ASC Topic 740, "Income Taxes" ("ASC 740"),  which 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 financial expenses.
Concentrations of credit risk	'
	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 and Switzerland. 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 the uncollectability of its accounts receivable using the specific identification method related to base rents, straight-line rent balances, expense reimbursements and other revenues. It 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 management's estimate of the collectability of accounts receivable.
Earnings (loss) per share	'
	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	'
	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 a 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. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
	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.
	The fair value was estimated at the date of grant using the following weighted average assumptions for the Black-Scholes model for the year ended December 31, 2011. During 2012 and 2013 there were no grants.
			December 31,
			2011
	Dividend yield			0	%
	Volatility			67	%
	Risk free interest			0.9%-1.7	%
	Expected term (years)			4.75
Treasury Shares	'
	Treasury Shares:
	During the past years, the Company repurchased certain of its 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 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	'
	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-tier 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 instrument (see note 1b(1)) are measured at fair value under ASC 820 on a recurring basis as of December 31,2012 and 2013.
Comprehensive income	'
	Comprehensive income:
	In June 2011, the FASB issued ASU 2011-05 Presentation of Comprehensive Income, codified in ASC 220 "Comprehensive Income". The guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The guidance also eliminates the option to present the components of other comprehensive income as part of the statement of equity. The Company adopted the new guidance commencing January 1, 2012.  The Company chose to present the Comprehensive Income in two separate but consecutive statements.
Accounting Pronouncements	'
	Accounting Pronouncements
	In July 2013, the FASB issued ASU 2013-11, Topic 740, " Income Taxes", which limits the situations in which unrecognized tax benefits are offset against a deferred tax asset for a net operating loss carry-forward, similar tax loss or tax credit carry forward. ASU 2013-11 is effective for reporting periods beginning after December 15, 2013. We intend to adopt this standard in 2014 and do not expect the adoption will have a material impact on our consolidated results of operations or financial condition.
