Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements are prepared according to United States generally accepted accounting principles (“U.S. GAAP”), applied on a consistent basis, as follows: a. Use of Estimates: The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company’s management evaluates estimates, including those related to accounts receivable and sales allowances, fair values of stock-based awards, deferred taxes and income tax uncertainties, and contingent liabilities. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. b. Financial Statements in U.S. Dollars: Most of the revenues and costs of VSI are denominated in United States dollars (“dollars”). Some of the subsidiaries’ revenues and costs are primarily incurred in Euros, the Pound Sterling, Canadian dollars and NIS; however, the Company’s management believes that the dollar is the primary currency of the economic environment in which VSI and each of its subsidiaries operate. Thus, the dollar is the Company’s functional and reporting currency. Accordingly, transactions denominated in currencies other than the functional currency are re-measured to the functional currency in accordance with ASC No. 830, c. Principles of Consolidation: The consolidated financial statements include the accounts of VSI and its wholly-owned subsidiaries, VSL, VSUK, VSG, VSF, VSC and VIRE. All intercompany transactions and balances have been eliminated upon consolidation. d. Cash Equivalents: Cash equivalents are short-term highly liquid investments that are readily convertible to cash with original maturities of three e. Short-Term Deposits: A short-term bank deposit is a deposit with a maturity of more than three one 0.55% 1.11% 0.30% 1.00%, December 31, 2016 2015, 0.15% December 31, 2016. December 31, 2015. f. Restricted Cash: Restricted cash is primarily invested in certificates of deposit and is used mostly as security for the Company’s lease commitments. The Company had no short-term restricted cash as of December 31, 2016 2015, $488 $468 December 31, 2016 2015, g. Property and Equipment: Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets at the following annual rates: % Computer equipment 33 Office furniture and equipment 7 - 15 Leasehold improvements Over the shorter of the lease term or estimated useful life h. Impairment of Long-Lived Assets: The Company’s long-lived assets are reviewed for impairment in accordance with ASC No. 360 may December 31, 2016, 2015 2014, i. Long-Term Lease Deposits: Long-term lease deposits include long-term deposits for offices. j. Revenue Recognition: The Company generates revenues in the form of software license fees and related maintenance and services fees. Maintenance and services primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available) and professional services (including training) that are not essential to functionality of the Company’s software. The Company sells its products worldwide directly to a network of distributors and VARs. The Company accounts for the sale of perpetual software in accordance with ASC No. 985 605, 985 605, 985 605 The Company determines the fair value based on the stand alone sales price charged for maintenance, and professional services. The Company has defined classes of transactions, based on the value of licensed software products purchased from the Company. The Company prices renewals for each class of transaction as a fixed percentage of the total gross value of licensed software products the customer purchased. Software license revenues are recognized when persuasive evidence of an arrangement exists, the software license has been delivered, there are no uncertainties surrounding product acceptance, there are no significant future performance obligations, the license fees are fixed or determinable and collection of the license fee is considered probable. Fees for arrangements with payment terms extending beyond customary payment terms are considered not to be fixed or determinable, in which case revenue is deferred and recognized when payments become due from the customer provided that all other revenue recognition criteria have been met. The Company recognizes revenues from the sale of term license arrangements, ratably, on a straight-line basis, over the term of the underlying maintenance contract, and is typically up to one The Company recognizes revenues from maintenance ratably over the term of the underlying maintenance contract term. The term of the maintenance contract is usually one Revenues from professional services consist mostly of time and material services and, accordingly, are recognized as the services are performed or when the service term has expired. Professional services bundled with licensed software and other software related elements are not essential to the functionality of the other elements of the arrangement. Revenues allocable to the services are recognized as the services are performed or when the service term has expired, using VSOE for such services. Deferred revenues represent unrecognized fees billed or collected for maintenance and professional services. The Company does not grant a right of return to its customers, except for one December 31, 2016, 2015 2014, k. Cost of Revenues: Cost of revenues consists of the cost of maintenance and services, resulting from costs associated with support, and professional services. l. Accounting for Stock-Based Compensation: The Company accounts for stock-based compensation in accordance with ASC No. 718, 718 The Company recognizes compensation expenses for the value of its awards granted based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 The Company applies ASC 718 505 50, 505 50. The Company selected the Black-Scholes-Merton option pricing model as the most appropriate fair value method for its stock options awards, whereas the fair value of restricted stock units is based on the market value of the underlying shares at the date of grant. The fair value of options granted to employees and non-employee directors is estimated at the date of grant using the following weighted average assumptions: Year ended December 31, 2016 2015 2014 Dividend yield 0 % 0% 0% Expected volatility 62.1 % 65% 60% - 64% Risk-free interest 1.42 % 1.94 - 2.00% 1.97 - 2.30% Expected life 6.25 6.25 6.25 The Company used its historical volatility in accordance with ASC 718. 110, zero may The non-cash compensation expenses related to employees and consultants for the years ended December 31, 2016, 2015 2014 $12,938, $7,794 $4,664, m. Research and Development Costs: Research and development costs are charged to the statement of operations as incurred. ASC No. 985 20, Based on the Company’s product development process, technological feasibility is established upon the completion of a working model. The Company does not incur material costs between the completion of the working model and the point at which the product is ready for general release. Therefore, research and development costs are charged to the statement of operations as incurred. n. Income Taxes: The Company accounts for income taxes in accordance with Accounting Standards Codification No. 740, ASC 740 two first second 50% o. Derivative Instruments: The Company’s primary objective for holding derivative instruments is to reduce its exposure to foreign currency rate changes. The Company reduces its exposure by entering into forward foreign exchange contracts with respect to operating expenses that are forecast to be incurred in currencies other than the U.S. dollar. A majority of the Company’s revenues and a majority of its operating expenditures are transacted in U.S. dollars. However, certain operating expenditures are incurred in or exposed to other currencies, primarily the NIS. The Company has established forecasted transaction currency risk management programs to protect against fluctuations in fair value and the volatility of future cash flows caused by changes in exchange rates. The Company’s currency risk management program includes forward foreign exchange contracts designated as cash flow hedges. These forward foreign exchange contracts generally mature within 12 Derivative instruments measured at fair value and their classification on the consolidated balance sheets are presented in the following table (in thousands): Liabilities as of Liabilities as of Notional Fair Notional Fair Foreign Exchange Forward Contract Derivatives in cash flow hedging relationships—included in accrued expenses and other liabilities $ 46,116 $ (479 ) $ 36,070 $ (331 ) For the years ended December 31, 2016 2015, $332 $307, December 31, 2016 2015. p. Concentrations of Credit Risks: Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, short-term deposits and trade receivables. The Company’s cash, cash equivalents and short-term deposits are invested in major banks mainly in the United States but also in the United Kingdom, France, Germany, Israel and Canada. Such deposits in the United States may The Company’s trade receivables are geographically diversified and derived primarily from sales to a network of distributors and VARs mainly in the United States and Europe. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation and account monitoring procedures. The Company performs ongoing credit evaluations of its channel partners and establishes an allowance for doubtful accounts based upon a specific review of all significant outstanding invoices. The Company writes off receivables when they are deemed uncollectible and having exhausted all collection efforts. q. Retirement and Severance Pay: VSI makes available to its employees a retirement plan (the “U.S. Plan”) that qualifies as a deferred salary arrangement under Section 401(k) may 100% 3% 50% 3% 5% may 80% Pursuant to Israel’s Severance Pay Law, Israeli employees are entitled to severance pay equal to one 14 1963 14”). 8.33% 14 The Company’s liability for severance pay for the employees of its French subsidiary is calculated pursuant to French law, according to which French employees are entitled to an indemnity (a statutory redundancy). The law provides for the payment of severance payment to any employee working for the French subsidiary for at least a year. VSUK makes available to certain eligible employees a pension plan whereby participants in the plan may 100% 3% Total Company expenses related to retirement and severance pay amounted to $3,775, $3,085 $2,651 December 31, 2016, 2015 2014, r. Fair Value of Financial Instruments: 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. A three • Level 1: • Level 2: • Level 3: 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. The carrying amounts of cash and cash equivalents, trade receivables, short-term deposits and trade payables approximate their fair value due to the short-term maturity of such instruments. s. Basic and Diluted Net Loss Per Share: Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, convertible preferred stock warrants stock, to the extent dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive. t. Contingent Liabilities: The Company accounts for its contingent liabilities in accordance with ASC No. 450 With respect to legal matters, provisions are reviewed and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter.

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	a. Use of Estimates: The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company’s management evaluates estimates, including those related to accounts receivable and sales allowances, fair values of stock-based awards, deferred taxes and income tax uncertainties, and contingent liabilities. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	b. Financial Statements in U.S. Dollars: Most of the revenues and costs of VSI are denominated in United States dollars (“dollars”). Some of the subsidiaries’ revenues and costs are primarily incurred in Euros, the Pound Sterling, Canadian dollars and NIS; however, the Company’s management believes that the dollar is the primary currency of the economic environment in which VSI and each of its subsidiaries operate. Thus, the dollar is the Company’s functional and reporting currency. Accordingly, transactions denominated in currencies other than the functional currency are re-measured to the functional currency in accordance with ASC No. 830,
Consolidation, Policy [Policy Text Block]	c. Principles of Consolidation: The consolidated financial statements include the accounts of VSI and its wholly-owned subsidiaries, VSL, VSUK, VSG, VSF, VSC and VIRE. All intercompany transactions and balances have been eliminated upon consolidation.

Revenue Recognition, Policy [Policy Text Block]	j. Revenue Recognition: The Company generates revenues in the form of software license fees and related maintenance and services fees. Maintenance and services primarily consist of fees for maintenance services (including support and unspecified upgrades and enhancements when and if they are available) and professional services (including training) that are not essential to functionality of the Company’s software. The Company sells its products worldwide directly to a network of distributors and VARs. The Company accounts for the sale of perpetual software in accordance with ASC No. 985 605, 985 605, 985 605 The Company determines the fair value based on the stand alone sales price charged for maintenance, and professional services. The Company has defined classes of transactions, based on the value of licensed software products purchased from the Company. The Company prices renewals for each class of transaction as a fixed percentage of the total gross value of licensed software products the customer purchased. Software license revenues are recognized when persuasive evidence of an arrangement exists, the software license has been delivered, there are no uncertainties surrounding product acceptance, there are no significant future performance obligations, the license fees are fixed or determinable and collection of the license fee is considered probable. Fees for arrangements with payment terms extending beyond customary payment terms are considered not to be fixed or determinable, in which case revenue is deferred and recognized when payments become due from the customer provided that all other revenue recognition criteria have been met. The Company recognizes revenues from the sale of term license arrangements, ratably, on a straight-line basis, over the term of the underlying maintenance contract, and is typically up to one The Company recognizes revenues from maintenance ratably over the term of the underlying maintenance contract term. The term of the maintenance contract is usually one Revenues from professional services consist mostly of time and material services and, accordingly, are recognized as the services are performed or when the service term has expired. Professional services bundled with licensed software and other software related elements are not essential to the functionality of the other elements of the arrangement.
