Organization, Consolidation and Presentation of Financial Statements [Abstract]

GENERAL


a.	ReWalk Robotics Ltd. (“RRL”, and together with its subsidiaries, the “Company”) was incorporated under the laws of the State of Israel on June 20, 2001 and commenced operations on the same date.


b.	RRL has two wholly-owned subsidiaries: (i) ReWalk Robotics Inc., incorporated under the laws of Delaware on February 15, 2012; and (ii) ReWalk Robotics GMBH. incorporated under the laws of Germany on January 14, 2013.

During the six months ended June 30, 2017, the Company issued and sold 3,701,620 ordinary shares at an average price of $1.74 per share under its ATM Offering Program (as defined in Note 8e). The gross proceeds to the Company were $6,447 thousand, and the net aggregate proceeds after deducting commissions, fees and offering expenses in the amount of $313 thousand were $6,134 thousand. As a result, from the inception of the ATM Offering Program in May 2016 until June 30, 2017, the Company has issued and sold 4,393,682 ordinary shares at an average price of $2.51 per share under its ATM Offering Program, with gross proceeds of $11.0 million, and net aggregate proceeds of $10.2 million after deducting commissions, fees and offering expenses in the amount of $781 thousand. The Company may raise up to $25 million under its ATM Offering Program pursuant to the terms of its agreement with the sales agent. However, due to limitations under the rules of Form S-3, which have applied to the Company since it filed its annual report on Form 10-K for the fiscal year ended December 31, 2016 on February 17, 2017, taking into account ordinary shares issued and settled under the Company’s ATM Offering Program since February 17, 2017, as of June 30, 2017, the Company may issue up to $7.3 million in primary offerings under its effective shelf registration statement on Form S-3 (File No. 333- 209833) (the “Form S-3”), including its ATM Offering Program, during the 12 months following February 17, 2017, unless and until it is no longer subject to such limitations. See Note 8e for more information about the Company’s ATM Offering Program and the related limitations under its Form S-3.


d.	The Company depends on one contract manufacturer. Reliance on this vendor makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields and costs. This vendor accounted for 0% and 12% of the Company's total trade payables as of June 30, 2017 and December 31, 2016, respectively.

On January 9, 2017, the Company announced its plan to reduce total operating expenses in 2017 by up to 30% as compared to 2016. These reductions will be achieved through a combination of targeted savings, including the completion of specific projects focused on quality improvement initiatives and efforts to reduce overall product cost, a realignment of and reduction in staffing to match the Company’s 2017 business goals, and a reduction in other corporate spending.

The Company had an accumulated deficit in the total amount of $119.2 million as of June 30, 2017 and further losses are anticipated in the development of its business. Those factors raise substantial doubt about the Company’s ability to continue as a going concern. The ability to continue as a going concern is dependent upon the Company obtaining the necessary financing to meet its obligations and repay its liabilities arising from normal business operations when they become due.

The Company intends to finance operating costs over the next twelve months with existing cash on hand, reductions in operating spend, issuances under the Company's ATM Offering Program or other future issuances of equity and debt securities, or through a combination of the foregoing.

The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and liabilities and commitments in the normal course of business.

The condensed consolidated financial statements for the three and six months ended June 30, 2017 do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from uncertainty related to the Company’s ability to continue as a going concern.

Accounting Policies [Abstract]

SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies applied in the audited consolidated financial statements of the Company as disclosed in the Company's annual report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 17, 2017, as amended on Form 10-K/A filed with the SEC on April 27, 2017 (the “2016 Form 10-K”), are applied consistently in these unaudited interim condensed consolidated financial statements.


b.	Recent Accounting Pronouncements:

Recently Implemented Accounting Pronouncements

Inventory - In July 2015, the FASB issued Accounting Standards Update 2015-11, “Simplifying the Measurement of Inventory.” The standard changes the inventory valuation method from the lower of cost or market to the lower of cost or net realizable value for inventory valued under the first-in, first-out or average cost methods. This standard is effective for fiscal years beginning after December 15, 2016, including interim periods and requires prospective adoption with early adoption permitted. The update was effective for the Company beginning January 1, 2017. The adoption of this standard did not materially impact the Company's financial statements.

Deferred Taxes - In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes", which simplifies the presentation of deferred income taxes. ASU 2015-17 provides presentation requirements to classify deferred tax assets and liabilities, along with any related valuation allowance, as noncurrent on the balance sheet. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. The Company elected to implement this ASU-2015-17 prospectively. The update was effective for the Company beginning January 1, 2017. The adoption of this standard did not materially impact the Company's financial statements.

Recent Accounting Pronouncements Not Yet Adopted

Revenues - In May 2014, the Financial Accounting Standards Board (the “FASB") issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In 2016, the FASB issued four amendments to ASU 2014-09. The standard is effective for public companies for annual and interim periods beginning after December 15, 2017. Early adoption is permitted as of one year prior to the current effective date. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company has not selected an implementation approach. The Company elected not to adopt the standard early and is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures.

Leases - In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months. Consistent with current generally accepted accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. This ASU requires additional disclosures. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. The ASU requires adoption based upon a modified retrospective transition approach. Early adoption is permitted. The Company has not yet determined whether it will elect early adoption and is currently evaluating the impact of the pending adoption of this ASU on the Company's consolidated financial statements and related disclosures.

Statement of Cash Flows - In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” The standard addresses several matters of diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows including the presentation of debt extinguishment costs and distributions received from equity method investments. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods and allows for retrospective adoption with early adoption permitted. The Company has not yet determined whether it will elect early adoption. The Company is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures.

Statement of Cash Flows - On November 17, 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force).” This ASU requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents are to be included with cash and cash equivalents when reconciling the beginning of period and end of period amounts shown on the statement of cash flows. ASU No. 2016-18 will be effective for the Company as of January 1, 2018. The Company does not expect the adoption to have a material impact on the Company's consolidated financial statements.

Share Based Compensation - On May 10, 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting.” This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. They will have to make all of the disclosures about modifications that are required today, in addition to disclosing that compensation expense hasn’t changed, if that’s the case. It also clarifies that a modification to an award could be significant and therefore require disclosure, even if modification accounting is not required. ASU No. 2017-09 will be effective for fiscal years beginning after December 15, 2017. Early adoption is permitted, including in any interim period for which financial statements have not yet been issued or made available for issuance. The ASU will be applied prospectively to awards modified on or after the adoption date. The Company is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures.


c.	Concentrations of Credit Risks:

Concentration of credit risk with respect to trade receivable is primarily limited to a customer to which the Company makes substantial sales. One customer represented 8% and 0% of the Company's trade receivable, net balance as of June 30, 2017 and December 31, 2016, respectively. As of June 30, 2017 and December 31, 2016 trade receivables are presented net of allowance for doubtful accounts in the amount of $324 thousand and $333 thousand, respectively and net of sales return reserve of $105 thousand as of June 30, 2017 and December 31, 2016.


d.	Warranty provision

The Company provides a two-year standard warranty for its products. The Company records a provision for the estimated cost to repair or replace products under warranty at the time of sale. Factors that affect the Company’s warranty reserve include the number of units sold, historical and anticipated rates of warranty repairs and the cost per repair.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES


a.	Purchase commitments:

The Company has contractual obligations to purchase goods from its contract manufacturer, Sanmina Corporation. Purchase obligations do not include contracts that may be canceled without penalty. As of June 30, 2017, non-cancelable outstanding obligations amounted to approximately $1.2 million.


b.	Royalties:

The Company’s research and development efforts are financed, in part, through funding from the Israel Innovation Authority, or the IIA (formerly known as the Israeli Office of the Chief Scientist in the Israel Ministry of Economy). During the six months ended June 30, 2017 the Company received $606 thousand from the IIA to fund its research and development efforts. Since the Company’s inception through June 30, 2017, the Company received funding from the IIA in the total amount of $1.3 million. Out of the $1.3 million in funding from the IIA, a total amount of $946 thousand were royalty bearing grants (as of June 30, 2017, the Company paid royalties to the IIA in the total amount of $50 thousand), while a total amount of $400 thousand was received in consideration of 5,237 convertible preferred A shares, which converted after our initial public offering in September 2014 into ordinary shares in a conversion ratio of 1 to 1. The Company is obligated to pay royalties to the IIA, 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. As of June 30, 2017, the contingent liability to the IIA amounted to $896 thousand.


c.	Liens:

As discussed in Note 6 to our audited consolidated financial statements included in the Company's annual report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on February 17, 2017, as amended on Form 10-K/A filed with the SEC on April 27, 2017 (the “2016 Form 10-K”), the Company is party to the Loan Agreement with Kreos pursuant to which Kreos extended a $20.0 million line of credit to the Company. In connection with the Loan Agreement, the Company granted Kreos a first priority security interest over all of its assets, including intellectual property and equity interests in its subsidiaries, subject to certain permitted security interests.

The Company's other long-term assets, which were in the amount of $855 thousand as of June 30, 2017, have been pledged as security in respect of a guarantee granted to a third party. Such deposit cannot be pledged to others or withdrawn without the consent of such third party.


d.	Legal Claims:

Occasionally the Company is involved in various claims, lawsuits, regulatory examinations, investigations and other legal matters arising, for the most part, in the ordinary course of business. The outcome of litigation and other legal matters is inherently uncertain. In making a determination regarding accruals, using available information, the Company evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings to which the Company is a party and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. Where the Company determines an unfavorable outcome is not probable or reasonably estimable, the Company does not accrue for any potential litigation loss. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of our defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the Company’s current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to the Company’s consolidated results of operations, liquidity or financial condition.

As set forth below, between September 2016 and January 2017, eight substantially similar putative securities class actions were filed against the Company. Four of these actions have been dismissed on procedural grounds, one was voluntarily dismissed and three are pending, including two actions which have been consolidated and one action brought by the plaintiffs whose actions were dismissed.


•	Dismissed Actions:

◦

On September 20, November 3, November 9, and November 10, 2016, respectively, four putative class actions on behalf of alleged shareholders that purchased or acquired the Company's ordinary shares pursuant and/or traceable to the registration statement used in connection with the Company's IPO were commenced in the Superior Court of the State of California, County of San Mateo. The actions were filed against the Company, certain of the Company's current and former directors and officers, and the underwriters of the Company's IPO. We refer to these actions as the “California State Court Actions.” The complaints in the California State Court Actions asserted various claims under the Securities Act. Each of the California State Court Actions was dismissed for lack of personal jurisdiction in January 2017.

◦

On January 24, 2017, a substantially similar class action was commenced in the United States District Court for the Northern District of California (Case No. 4:17-cv-362) against the same defendants as in the California State Court Actions plus certain additional defendants. This action is referred to as the “California Federal Court Action.” On March 23, 2017, this case was voluntarily dismissed.


•	Pending Actions:

◦

On or about October 31, 2016, a class action with claims substantially similar to the California State Court Actions was commenced in the Massachusetts Superior Court, Suffolk County, by a different plaintiff (Civ. Action No. 16-3336), alleging claims under Section 11 of the Securities Act against the Company, certain of the Company's current and former directors and officers, and the underwriters of the Company's IPO, and alleging claims under Section 15 of the Securities Act against the Company and certain of the Company's current and former directors and officers.

◦

On or about November 30, 2016, a substantially similar class action was commenced in the Massachusetts Superior Court, Suffolk County, by a different plaintiff (Civ. Action No. 16-3670) alleging claims under Sections 11 and 15 of the Securities Act against the same defendants as in the action commenced on October 31, 2016, and also alleging claims under Section 12(a)(2) of the Securities Act against the Company, certain of the Company's current and former directors and officers, and the underwriters of the Company's IPO. This action was ordered consolidated in the Massachusetts Superior Court, Suffolk County on January 9, 2017 with the action commenced on October 31, 2016, and the two actions are referred to as the “Consolidated Massachusetts State Court Actions”.

◦

On or about January 31, 2017, a substantially similar class action was commenced in the United States District Court for the District of Massachusetts (Case No. 1:17-cv-10169) by four of the same plaintiffs who commenced the California State Court Actions, and two additional plaintiffs, alleging claims under Sections 11 and 12(a)(2) of the Securities Act against the Company, certain of the Company's current and former directors and officers, and the underwriters of the Company's IPO, and alleging claims under Section 15 of the Securities Act against certain of the Company's current and former directors and officers. This action is referred to as the “Massachusetts Federal Court Action.”

The plaintiffs in the Consolidated Massachusetts State Court Actions filed a consolidated amended complaint on March 20, 2017. The Company moved to dismiss the Consolidated Massachusetts State Court Actions on June 2, 2017.

The complaints in all of the actions listed above allege that the Company's registration statement used in connection with its IPO failed to disclose that the Company was unprepared or unable to comply with certain regulatory special controls and to provide the FDA with a postmarket surveillance study on the Company's ReWalk Personal device, and that, as a result of such alleged omission, the plaintiffs suffered damages. The Company believes that the allegations made in the complaints are without merit and intends to defend itself vigorously against the complaints relating to the three pending actions.

Based on information currently available and the early stage of the litigation, the Company is unable to reasonably estimate a possible loss or range of possible losses, if any, with regard to these lawsuits; therefore, no litigation reserve has been recorded in the Company's consolidated balance sheet as of June 30, 2017. The Company will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is probable that a loss will be incurred and the amount of the loss is reasonably estimable.

LOAN AGREEMENT WITH KREOS AND RELATED WARRANT TO PURCHASE ORDINARY SHARES	6 Months Ended

Debt Disclosure [Abstract]
LOAN AGREEMENT WITH KREOS AND RELATED WARRANT TO PURCHASE ORDINARY SHARES	LOAN AGREEMENT WITH KREOS AND RELATED WARRANT TO PURCHASE ORDINARY SHARES On December 30, 2015, the Company entered into the loan agreement (the "Loan Agreement") with Kreos Capital V (Expert Fund) Limited ("Kreos"), pursuant to which Kreos extended a line of credit to the Company in the amount of $20.0 million. For more information, see Note 6 to our audited consolidated financial statements included in our 2016 Form 10-K. On June 9, 2017, the Company and Kreos entered into the First Amendment of the Loan Agreement (the "Loan Amendment"). As of that date the outstanding principal amount under the Loan Agreement (the "Outstanding Principal") was $17.2 million. Under the Loan Amendment $3.0 million of the Outstanding Principal is extended by an additional 3 years with the same interest rate and is subject to repayment in accordance with, and subject to the terms of, a secured convertible promissory note (the "Kreos Convertible Note") into up to 2,365,931 ordinary shares of the Company at a fixed conversion price of $1.268 per share (subject to customary antidilution adjustments), thus reducing the Outstanding Principal Amount amount to $14.2 million. Kreos may convert the then-outstanding principal under the Kreos Convertible Note in whole or in part, in one or more occasions, at any time until the earlier of (i) the maturity date of June 9, 2020 or (ii) a Change of Control, as defined in the Loan Agreement. The Outstanding Principal Amount under the Loan Agreement is not convertible and remains subject to repayment in accordance with the terms and conditions of the Loan Agreement, provided that such amount shall be repaid by the Company in accordance with an amended repayment schedule. The Company concluded that the exchange of the $3.0 million for the convertible promissory note is not a troubled debt restructuring under applicable accounting guidance because the lenders did not grant a concession. The modification was analyzed under ASC 470 Debt to determine if extinguishment accounting was applicable. Under ASC 470-50-40-10 a modification or an exchange that adds or eliminates a substantive conversion option as of the conversion date is always considered substantial and requires extinguishment accounting. Since this modification added a substantive conversion option, extinguishment accounting is applicable. The difference between the fair value of the new debt with the pre-modification carrying amount of the old debt represented a loss on extinguishment in the amount of $313 thousand. According to the Loan Agreement the repayment period will be extended to 36 months if the Company raises $20 million or more in connection with the issuance of shares of its capital stock (including debt securities convertible into shares of the Company’s capital stock). As of June 30, 2017 the Company had raised more than $20 million and therefore the repayment period was extended by an additional 12 months to 36 months.

RESEARCH COLLABORATION AND LICENSE AGREEMENT	6 Months Ended
RESEARCH COLLABORATION AND LICENSE AGREEMENT	Jun. 30, 2017
Research and Development [Abstract]
RESEARCH COLLABORATION AGREEMENT AND LICENSE AGREEMENT	RESEARCH COLLABORATION AGREEMENT AND LICENSE AGREEMENT On May 16, 2016, the Company entered into a Research Collaboration Agreement (“Collaboration Agreement”) and an Exclusive License Agreement (“License Agreement”) with Harvard. Under the Collaboration Agreement, Harvard and the Company have agreed to collaborate on research regarding the development of lightweight “soft suit” exoskeleton system technologies for lower limb disabilities, which are intended to treat stroke, multiple sclerosis, mobility limitations for the elderly and other medical applications. The Company has committed to pay in quarterly installments for the funding of this research, subject to a minimum funding commitment under applicable circumstances. The Collaboration Agreement will expire on May 16, 2021. Under the License Agreement, Harvard has granted the Company an exclusive, worldwide royalty-bearing license under certain patents of Harvard relating to lightweight “soft suit” exoskeleton system technologies for lower limb disabilities, a royalty-free license under certain related know-how and the option to obtain a license under certain inventions conceived under the joint research collaboration. The License Agreement requires the Company to pay Harvard an upfront fee, reimbursements for expenses that Harvard incurred in connection with the licensed patents, royalties on net sales and several milestone payments contingent upon the achievement of certain product development and commercialization milestones. The License Agreement will continue in full force and effect until the expiration of the last-to-expire valid claim of the licensed patents. As of June 30, 2017, the Company did not achieve any of these milestones, and is evaluating the likelihood that the milestones will be achieved on a quarterly basis. Moreover, since such royalties are dependent on future product sales which are neither determinable nor reasonably estimable, these royalty payments are not recorded on the Company's condensed consolidated balance sheet as of June 30, 2017. The Company's total payment obligation under the Collaboration Agreement and the License Agreement is $6.3 million, some of it is subject to a minimum funding commitment under applicable circumstances as indicated above. The Company has recorded expense in the amount of $383 thousand and $1.1 million during the three months period ended June 30, 2017 and June 30, 2016 respectively. The Company has recorded expenses in the amount of $689 thousand and $1.1 million during the six months period ended June 30, 2017 and June 30, 2016 respectively. Those expenses are part of the total payment obligation indicated above, as research and development expenses related to the License Agreement and to the Collaboration Agreement.

SHAREHOLDERS' EQUITY

SHAREHOLDERS’ EQUITY



	a.	Share option plans:

As of June 30, 2017, and December 31, 2016, the Company had reserved 583,423 and 380,153 ordinary shares, respectively, for issuance to the Company’s and its affiliates’ respective employees, directors, officers and consultants pursuant to equity awards granted under the Company's 2014 Incentive Compensation Plan (the “2014 Plan”).

Options to purchase ordinary shares generally vest over four years, with certain options to non-employee directors vesting quarterly over one year. Any option that is forfeited or canceled before expiration becomes available for future grants under the 2014 Plan.

The fair value for options granted during the six months ended June 30, 2017 and June 30, 2016 was estimated at the date of the grant using a Black-Scholes-Merton option pricing model with the following assumptions:



	Six Months Ended June 30,
	2017	2016
Expected volatility	56% - 58%	53% - 60%
Risk-free rate	1.85% - 2.07%	1.28%-1.60%
Dividend yield	—%	—%
Expected term (in years)	5.31-6.11	5.31-6.11
Share price	$1.3- $2.1	$8.48- $11.88

The fair value of restricted share units (“RSUs”) granted is determined based on the price of the Company's ordinary shares on the date of grant.

A summary of employee options to purchase ordinary shares and RSUs during the six months ended June 30, 2017 is as follows:



	Six Months Ended June 30, 2017
	Number		Average exercise price		Average remaining contractual life (in years) (1)	Aggregate intrinsic value (in thousands)
Options and RSUs outstanding at the beginning of the period	2,251,014		$	6.47	7.80	$	1,740
Options granted	401,846		2.03
RSUs granted	230,484		—

Options and RSUs outstanding at the end of the period	2,635,209		$	5.38	7.54	$	912

Options exercisable at the end of the period	1,217,605		$	5.92	6.36	$	262


(1)	Calculation of weighted average remaining contractual term does not include RSUs, which have an indefinite contractual term.


(2)	During the six months period ended June 30, 2017, the aggregate number of ordinary shares that were issued pursuant to RSUs that became vested and options that were exercised on a net basis was 64,332 ordinary shares.

The weighted average grant date fair value of options granted during the six months ended June 30, 2017 and June 30, 2016 was $1.10 and $4.79, respectively. The weighted average grant date fair value of RSUs granted during the six month period ended June 30, 2017 and June 30, 2016 was $2.01 and $9.36, respectively.

The aggregate intrinsic value in the table above represents the total intrinsic value that would have been received by the option holders had all option holders that hold options with positive intrinsic value exercised their options on the last date of the exercise period. Total intrinsic value of options exercised for each of the three months ended June 30, 2017 and June 30, 2016 was $25 thousand and $830 thousand respectively. As of June 30, 2017, there were $5.9 million of total unrecognized compensation costs related to non-vested share-based compensation arrangements granted under the Company's 2012 Equity Incentive Plan and its 2014 Plan. This cost is expected to be recognized over a period of approximately 2.3 years.

The number of options and RSUs outstanding as of June 30, 2017 is set forth below, with options separated by range of exercise price.



Range of exercise price	Options and RSUs outstanding as of June 30, 2017	Weighted average remaining contractual life (years) (1)	Options exercisable as of June 30, 2017	Weighted average remaining contractual life (years) (1)

(1)	Calculation of weighted average remaining contractual term does not include the RSUs that were granted, which have an indefinite contractual term.

On June 27, 2017, at the annual meeting of shareholders, the Company’s shareholders voted on, and approved by the requisite majority, a one-time equity award exchange program (the “Exchange Program”). If implemented, the Exchange Program will allow the Company to cancel certain outstanding stock options issued under the 2014 Plan currently held by some of the Company's employees and executive officers in exchange for the grant under the 2014 Plan of a lesser number of equity awards, either in the form of stock options with exercise prices equal to the market value of the Company's ordinary shares on the date of grant or in the form of RSUs, as will be determined by the Company's board of directors, prior to commencement of the Exchange Program (collectively, the “New Awards”). The exchange ratio will be designed to result in a “value-for-value” exchange pursuant to which the Company will grant a new equity award with a value approximately equal to the value of the options that are surrendered. The Company will use the 52-week high closing price of its ordinary shares (as measured at the commencement of the Exchange Program) as a threshold for options eligible to be exchanged. The New Awards issued in exchange for outstanding vested or unvested stock options will vest over a three-year period, with one-third (1/3) vesting on the first anniversary of the date of grant and one-third (1/3) on each of the next two successive anniversaries.

Participation in the Exchange Program will be voluntary. The Exchange Program will only be open to certain stock option holders employed by the Company or providing services to the Company at the time of the Exchange Program, including certain officers. The Company's non-employee directors and retirees will not be eligible to participate in the Exchange Program. In addition, the Exchange Program will not be offered to employees located in countries where the Company determines that it is either impractical or undesirable to offer the Exchange Program. Following the approval by the Company's shareholders at the annual meeting of shareholders, the Board will determine whether and when to initiate the Exchange Program and any exchange offer made to implement the Exchange Program. However, the Company must commence the Exchange Program within 12 months following the date of shareholder approval. The stock options exchanged pursuant to the Exchange Program will be canceled and the ordinary shares underlying such options will become available for issuance under the 2014 Plan.



	b.	Share-based awards to non-employee consultants:

The Company granted options to a non-employee consultant on March 12, 2007, which were exercised during the six months ended June 30, 2017. The Company granted 1,500 fully vested RSUs on January 1, 2017 to a non-employee consultant. As of June 30, 2017, there are no outstanding options or RSUs held by non-employee consultants.



	c.	Warrants to purchase ordinary shares:

The following table summarizes information about warrants outstanding and exercisable as of June 30, 2017:

	e.	At-the-market offering program:

On May 10, 2016, the Company entered into an equity distribution agreement (the “Equity Distribution Agreement”) with Piper Jaffray, pursuant to which it may offer and sell, from time to time, ordinary shares having an aggregate offering price of up to $25 million, through Piper Jaffray acting as its agent. Subject to the terms and conditions of the Equity Distribution Agreement, Piper Jaffray will use its commercially reasonable efforts to sell on the Company’s behalf all of the ordinary shares requested to be sold by the Company, consistent with its normal trading and sales practices. Piper Jaffray may also act as principal in the sale of ordinary shares under the Equity Distribution Agreement. Sales may be made under the Company's registration statement on Form S-3, which was declared effective on May 9, 2016 (the “Form S-3”), in what may be deemed “at-the-market” equity offerings as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “ATM Offering Program”). Sales may be made directly on or through the NASDAQ Capital Market, the existing trading market for the Company's ordinary shares, to or through a market maker other than on an exchange or otherwise, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices, and/or any other method permitted by law, including in privately negotiated transactions. Piper Jaffray is entitled to compensation at a fixed commission rate of 3.0% of the gross sales price per share sold through it as agent under the Equity Distribution Agreement. Where Piper Jaffray acts as principal in the sale of ordinary shares under the Equity Distribution Agreement, such rate of compensation will not apply, but in no event will the total compensation of Piper Jaffray, when combined with the reimbursement of Piper Jaffray for the out-of-pocket fees and disbursements of its legal counsel, exceed 8.0% of the gross proceeds received from the sale of the ordinary shares. The Company is not required to sell any of its ordinary shares at any time.

The Company may raise up to $25 million under its ATM Offering Program pursuant to the terms of its agreement with the sales agent. However, due to limitations under the rules of Form S-3, which have applied to the Company since it filed its annual report on Form 10-K for the fiscal year ended December 31, 2016 on February 17, 2017, taking into account ordinary shares issued and settled under the Company’s ATM Offering Program since February 17, 2017, as of June 30, 2017, the Company may issue up to $7.3 million in primary offerings under its effective shelf registration statement on Form S-3 (File No. 333- 209833) (the “Form S-3”), including its ATM Offering Program, during the 12 months following February 17, 2017, unless and until it is no longer subject to such limitations.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2017
Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles and standards of the Public Company Accounting Oversight Board for interim financial information. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States for complete financial statements. In the opinion of management, the accompanying financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company's (i)consolidated financial position as of June 30, 2017, (ii) consolidated results of operations for the three and six months ended June 30, 2017 and (iii) consolidated cash flows for the six months ended June 30, 2017. The results for the three and six months periods ended June 30, 2017, as applicable, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: Recently Implemented Accounting Pronouncements Inventory - In July 2015, the FASB issued Accounting Standards Update 2015-11, “Simplifying the Measurement of Inventory.” The standard changes the inventory valuation method from the lower of cost or market to the lower of cost or net realizable value for inventory valued under the first-in, first-out or average cost methods. This standard is effective for fiscal years beginning after December 15, 2016, including interim periods and requires prospective adoption with early adoption permitted. The update was effective for the Company beginning January 1, 2017. The adoption of this standard did not materially impact the Company's financial statements. Deferred Taxes - In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes", which simplifies the presentation of deferred income taxes. ASU 2015-17 provides presentation requirements to classify deferred tax assets and liabilities, along with any related valuation allowance, as noncurrent on the balance sheet. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. The Company elected to implement this ASU-2015-17 prospectively. The update was effective for the Company beginning January 1, 2017. The adoption of this standard did not materially impact the Company's financial statements. Recent Accounting Pronouncements Not Yet Adopted Revenues - In May 2014, the Financial Accounting Standards Board (the “FASB") issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In 2016, the FASB issued four amendments to ASU 2014-09. The standard is effective for public companies for annual and interim periods beginning after December 15, 2017. Early adoption is permitted as of one year prior to the current effective date. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. The Company has not selected an implementation approach. The Company elected not to adopt the standard early and is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures. Leases - In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than 12 months. Consistent with current generally accepted accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. This ASU requires additional disclosures. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. The ASU requires adoption based upon a modified retrospective transition approach. Early adoption is permitted. The Company has not yet determined whether it will elect early adoption and is currently evaluating the impact of the pending adoption of this ASU on the Company's consolidated financial statements and related disclosures. Statement of Cash Flows - In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” The standard addresses several matters of diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows including the presentation of debt extinguishment costs and distributions received from equity method investments. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods and allows for retrospective adoption with early adoption permitted. The Company has not yet determined whether it will elect early adoption. The Company is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures. Statement of Cash Flows - On November 17, 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force).” This ASU requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents are to be included with cash and cash equivalents when reconciling the beginning of period and end of period amounts shown on the statement of cash flows. ASU No. 2016-18 will be effective for the Company as of January 1, 2018. The Company does not expect the adoption to have a material impact on the Company's consolidated financial statements. Share Based Compensation - On May 10, 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting.” This ASU clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. They will have to make all of the disclosures about modifications that are required today, in addition to disclosing that compensation expense hasn’t changed, if that’s the case. It also clarifies that a modification to an award could be significant and therefore require disclosure, even if modification accounting is not required. ASU No. 2017-09 will be effective for fiscal years beginning after December 15, 2017. Early adoption is permitted, including in any interim period for which financial statements have not yet been issued or made available for issuance. The ASU will be applied prospectively to awards modified on or after the adoption date. The Company is currently evaluating the impact of the pending adoption of this ASU on its consolidated financial statements and related disclosures.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
