Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 – Summary of Significant Accounting Policies Nature of Operations VASCO Data Security International, Inc. and its wholly owned subsidiaries design, develop, market and support hardware and software security systems that manage and secure access to information assets. VASCO has operations in Austria, Australia, Belgium, Brazil, China, France, India, Japan, The Netherlands, Singapore, Switzerland, the United Arab Emirates, the United Kingdom (U.K)., and the United States (U.S.). Principles of Consolidation The consolidated financial statements include the accounts of VASCO Data Security International, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. As further described in Note 3, during January 2011 we acquired 100% of the stock of DigiNotar B.V. Effective September 20, 2011, DigiNotar B.V. was declared bankrupt in The Netherlands, transferring effective control over DigiNotar B.V. to the bankruptcy trustee. Accordingly, assets, liabilities and operating activities related to DigiNotar B.V. are reflected as discontinued operations. Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Foreign Currency Translation and Transactions The financial position and results of the operations of the majority of the company’s foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing during the year. Translation adjustments arising from differences in exchange rates are charged or credited to other comprehensive income. Losses resulting from foreign currency transactions were $1,247, $1,382, and $624 in 2015, 2014, and 2013, respectively, and are included in other income (expense) in the consolidated statements of operations. The financial position and results of our operations in Canada, Singapore, and Switzerland are measured in U.S. Dollars. For these subsidiaries, gains and losses that result from foreign currency transactions are included in the consolidated statements of operations in other income (expense). Revenue Recognition We recognize revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605, Software – Revenue Recognition Revenue Recognition – Multiple Element Arrangements Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable. In multiple-element arrangements, some of our products are accounted for under the software provisions of ASC 985-605 and others under the provisions that relate to the sale of non-software products. In our typical multiple-element arrangement, the primary deliverables include: 1. a client component (i.e., an item that is used by the person being authenticated in the form of either a new standalone hardware device or software that is downloaded onto a device the customer already owns), 2. host system software that is installed on the customer’s systems (i.e., software on the host system that verifies the identity of the person being authenticated) or licenses for additional users on the host system software if the host system software had been installed previously, and 3. post contract support (“PCS”) in the form of maintenance on the host system software or support. Our multiple-element arrangements may also include other items that are usually delivered prior to the recognition of any revenue and incidental to the overall transaction such as initialization of the hardware device, customization of the hardware device itself or the packaging in which it is delivered, deployment services where we deliver the device to our customer’s end-use customer or employee and, in some limited cases, professional services to assist with the initial implementation of a new customer. In multiple-element arrangements that include a hardware client device, we allocate the selling price among all elements, delivered and undelivered, based on our internal price lists and the percentage of the selling price of that element, per the price list, to the total of the estimated selling price of all of the elements per the price list. Our internal price lists for both delivered and undelivered elements were determined to be reasonable estimates of the selling price of each element based on a comparison of actual sales made to the price list for each item delivered and to vendor specific objective evidence (VSOE) for undelivered items. Undelivered elements primarily are PCS. The method by which we determine VSOE has validated that the price lists are reasonable estimates of the selling price for PCS. The estimated selling price of PCS items is based on an established percentage of the user license fee attributable to the specific software and is applied consistently to all PCS arrangements. The percentage we use to establish VSOE, which is also generally consistent with the percentage used in the price list, is developed using the “bell curve method”. Under this method, we conclude VSOE exists when a substantial majority of PCS renewals are within a narrow range of pricing. In multiple-element arrangements that include a software client device, we account for each element under the standards of ASC 985-605 related to software. When software client devices and host software are delivered elements, we use the Residual Method (ASC 605-25) for determining the amount of revenue to recognize for token and software licenses if we have VSOE for all of the undelivered elements. Any discount provided to the customer is applied fully to the delivered elements in such an arrangement. VSOE of fair value of PCS agreements is based on customer renewal transactions on a worldwide basis. In sales arrangements where VSOE of fair value has not been established, revenue for all elements is deferred and amortized over the life of the arrangement. For transactions other than multiple-element arrangements, we recognize revenue as follows: 1. Hardware Revenue and License Fees: 2. Maintenance and Support Agreements: 3. Services: 4. Consulting and Education Services: We recognize revenue from sales to distributors and resellers on the same basis as sales made directly to customers. We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable. For large-volume transactions, we may negotiate a specific price that is based on the number of users of the software license or quantities of hardware supplied. The per unit prices for large-volume transactions are generally lower than transactions for smaller quantities and the price differences are commonly referred to as volume-purchase discounts. All revenue is reported on a net basis, excluding any sales or value added taxes. Cash and Cash Equivalents Cash and cash equivalents are stated at cost plus accrued interest, which approximates fair value. Cash equivalents are high-quality short term money market instruments and commercial paper with maturities at acquisition of three months or less. Cash and cash equivalents are held by a number of U.S. and non-U.S. commercial banks and money market investment funds. Short Term Investments Short term investments are stated at cost plus accrued interest, which approximates fair value. Short term investments are high-quality commercial paper and bank certificates of deposit with maturities at acquisition of more than three months and less than twelve months. Accounts Receivable and Allowance for Doubtful Accounts The credit worthiness of customers is reviewed prior to shipment. A reasonable assurance of collection is a requirement for revenue recognition. Verification of credit and/or the establishment of credit limits are part of the customer contract administration process. Credit limit adjustments for existing customers may result from the periodic review of outstanding accounts receivable. The company records trade accounts receivable at invoice values, which are generally equal to fair value. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for goods and services. We analyze accounts receivable balances, customer credit-worthiness, current economic trends and changes in our customer payment timing when evaluating the adequacy of the allowance for doubtful accounts. The allowance is based on a specific review of all significant past-due accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required. Inventories Inventories, consisting principally of hardware and component parts, are stated at the lower of cost or market. Cost is determined using the first-in-first-out (FIFO) method. We write down inventory where it appears that the carrying cost of the inventory may not be recovered through subsequent sale of the inventory. We analyze the quantity of inventory on hand, the quantity sold in the past year, the anticipated sales volume in the form of sales to new customers as well as sales to previous customers, the expected sales price and the cost of making the sale when evaluating the valuation of our inventory. If the sales volume or sales price of a specific model declines significantly, additional write downs may be required. Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets ranging from three to seven years. Additions and improvements are capitalized, while expenditures for maintenance and repairs are charged to operations as incurred. Gains or losses resulting from sales or retirements are recorded as incurred, at which time related costs and accumulated depreciation are removed from the accounts. Research and Development Costs Costs for research and development, principally the design and development of hardware, and the design and development of software prior to the determination of technological feasibility, are expensed as incurred on a project-by-project basis. Software Development Costs We capitalize software development costs in accordance with ASC 985-20, Costs of Software to be Sold, Leased, or Marketed. Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect of a change in tax rates on deferred tax assets and liabilities and in income in the period that includes the enactment date. We monitor our potential income tax exposures as required by ASC 740, Income Taxes We have significant net operating loss and other deductible carryforwards in certain jurisdictions available to reduce the liability on future taxable income. A valuation allowance has been provided to offset some of these future benefits because we have not determined that their realization is more likely than not. Fair Value of Financial Instruments At December 31, 2015, and 2014, our financial instruments were cash equivalents, short term investments, accounts receivable, accounts payable and accrued liabilities. The estimated fair value of our financial instruments has been determined by using available market information and appropriate valuation methodologies, as defined in ASC 820, Fair Value Measurements. Accounting for Leases All of our leases are operating leases. Rent expense on facility leases is charged evenly over the life of the lease, regardless of the timing of actual payments. Goodwill and Other Intangibles We account for goodwill and intangible assets in accordance with ASC 350 Intangibles – Goodwill and Other We assess the impairment of goodwill each November or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment review include significant underperformance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or the strategy for our overall business, and significant negative industry or economic trends. In accordance with ASC 350, we consider the company to be one reporting unit. Fair value is determined using a market approach using our stock price which is a level 1 valuation, as defined by ASC 820, Fair Value Measurements Stock-Based Compensation We have stock-based employee compensation plans, which are described more fully in Note 9. ASC 718, Compensation-Stock Compensation Warranty Warranties are provided on the sale of certain of our products and an accrual for estimated future claims is recorded at the time revenue is recognized. We estimate the cost based on past claims experience, sales history and other considerations. We regularly assess the adequacy of our estimates and adjust the amounts as necessary. Our standard practice is to provide a warranty on our hardware products for either a one or two year period after the date of purchase. Customers may purchase extended warranties covering periods from one to four years after the standard warranty period. We defer the revenue associated with the extended warranty and recognize it into income on a straight-line basis over the extended warranty period. We have historically experienced minimal actual claims over the warranty period. Recently Issued Accounting Pronouncements In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ASU 2014-9 is effective for annual periods beginning after December 15, 2016, and interim periods within such annual periods, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers We are currently evaluating the impact of our pending adoption of ASU 2014-09 and ASU 2015-14 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard and whether we will elect early adoption.

Silanis revenue and net income (loss) included in the results of operations for the year ended December 31, 2015 were $541 and $(2,168), respectively. Acquisition-related expense recognized during 2015 of approximately $2,374 is recorded in general and administrative expenses in the Consolidated Statements of Operations. Aggregate Purchase Price Allocation Total aggregate Purchase Price has been allocated to the tangible and intangible assets and to liabilities assumed based on their respective estimated acquisition-date fair values. The measurement period for purchase price allocations ends as soon as information on the facts and circumstances becomes available, but cannot exceed twelve months. If new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized for assets acquired and liabilities assumed, the Company will adjust the amounts recognized in accordance with U.S. GAAP. The preliminary estimated purchase price allocation is summarized in the following table: Tangible assets and liabilities Cash $ 514 Accounts receivable, net 4,471 Other current assets 4,234 Property and equipment 416 Current liabilities (16,896 ) Other non-current liabilities (8,070 ) Intangible assets 30,000 Goodwill 60,331 Net assets acquired $ 75,000 Accounts receivable acquired were recorded at gross contractual amounts receivable which approximates fair value. We expect gross contractual amounts receivable at the acquisition date to be collected in a relatively short period of time. Other assets acquired include unused investment tax credits of $340, future tax benefit of foreign net operating loss carryforwards of $7,004, future tax benefits of research and development expenses and other carryforwards of $4,217. A full valuation allowance of $11,561 has been recorded as realization of the tax assets has been deemed not to be more likely than not. The excess of purchase consideration over net assets assumed was recorded as goodwill, which represents the strategic value assigned to Silanis, including expected benefits from synergies resulting from the acquisition, as well as the knowledge and experience of the workforce in place. In accordance with applicable accounting standards, goodwill is not amortized and will be tested for impairment at least annually, or more frequently, if certain indicators are present. Goodwill and intangible assets related to this acquisition are not deductible for tax purposes. Based on preliminary estimates of the acquisition valuation, $30,000 of the purchase price has been allocated to identifiable intangible assets. The following table summarizes the major classes of intangible assets, as well as the respective estimated weighted-average amortization periods: Estimated Weighted- (000s) Identifiable Intangible Assets Trademarks and tradenames $ 200 2.0 Technology 29,000 5.0 Patents 100 5.0 Non-compete agreements 300 5.0 Customer Relationships 400 5.0 $ 30,000 Silanis was acquired on November 25, 2015. Due to the short period of time between the acquisition date and December 31, 2015, the complex process of determining all assets acquired and all liabilities assumed and the determination of the fair value thereof, the accounting for the business combination was not complete as of December 31, 2015, nor did any events occur subsequent to the balance sheet date that required a reassessment of the estimates recorded at December 31, 2015. The estimated fair values of all assets acquired and all liabilities assumed are based on preliminary estimates of fair values as of the acquisition date. Management believes the fair values recognized for the assets acquired and liabilities assumed are based on reasonable estimates and assumptions. The fair value of the acquired assets and liabilities assumed are provisional pending finalization of valuations for those assets and liabilities. Preliminary fair value estimates may change as additional information becomes available. There can be no assurance that the final determination will not result in material changes from these preliminary amounts. Amounts preliminarily allocated to tangible assets, assumed liabilities, intangible assets and goodwill may change significantly, and amortization methods and useful lives may differ from the assumptions that have been used in these preliminary estimates, any of which could result in a material change to the purchase price allocation and operating expenses. Unaudited Pro Forma Financial Information The following unaudited pro forma financial information presents the results of operations as if the acquisition had taken place on January 1, 2014. These amounts were prepared in accordance with the acquisition method of accounting under existing standards and are not necessarily indicative of the results of operations that would have occurred if the acquisition had been completed on the first day of 2014, nor are they indicative of our future operating results. Income tax impacts resulting from pro forma adjustments were calculated utilizing the statutory income tax rate of 35% for the years ended December 31, 2015 and 2014. These unaudited pro forma amounts include the following adjustments to historical results shown net of tax; • To reflect estimated amortization of acquired identifiable intangible assets of $6,060 and $6,060 for the year ended December 31, 2015 and 2014, respectively. • To reflect estimated amortization of fair value adjustment of acquired deferred revenue of $(4,000) and $0 for the year ended December 31, 2015 and 2014, respectively. • To reclassify non-recurring transaction expenses of $5,812 from 2015 to 2014. • To reverse benefit of certain refundable tax credits of $1,021 and $1,588 for the year ended December 31, 2015 and 2014, respectively.

Similarly, long-term deferred tax assets and liabilities are netted by tax jurisdiction. Earnings of certain subsidiaries are deemed available for distribution. At December 31, 2015 and 2014, unremitted foreign earnings available for distribution are $22,672, and $19,849, respectively. The deferred tax liability for the incremental U.S. tax to be paid upon remittance as dividends at December 31, 2015 and 2014 was $137 and $955, respectively. The earnings of certain designated subsidiaries remain permanently invested. At December 31, 2015 and 2014, total unremitted foreign earnings considered permanently invested are $131,327 and $83,122, respectively. It is not practicable to estimate the incremental U.S. tax liability which would be incurred if these earnings were repatriated. At December 31, 2015, we held $30,018 of cash in banks in the United States and $48,504 of cash in banks outside of the United States. Of the cash in banks outside of the United States, $45,520 is not subject to significant repatriation restrictions, but may be subject to tax upon repatriation. Cash in banks outside of the United States includes $29,335 held in tax jurisdictions where we consider retained earnings to be available for distribution and $19,169 held in jurisdictions where we consider retained earnings to be permanently invested. A portion of tax benefits related to certain restricted stock and stock options are credited to additional paid-in capital. For the years ended December 31, 2015, 2014, and 2013, credits to additional paid-in capital were $318, $253, and $3,318, respectively U.S. foreign tax credit carryforwards expiring in 2023 were $3,309 at December 31, 2015. We have not provided a valuation reserve for the foreign tax credits as we believe it is more likely than not they will be realized due to our tax strategy to distribute foreign earnings to utilize foreign tax credits prior to expiration. At December 31, 2015, we had foreign and state net operating loss (NOL) carryforwards and other foreign deductible carryforwards as shown in the following table; Carryforward Deferred Valuation Expiration NOL Carryforward Canada $ 28,691 $ 7,379 $ (7,379 ) 2027-2035 Other foreign 3,850 1,241 (1,056 ) None U.S. states 4,853 248 (133 ) 2019-2027 37,394 8,868 (8,568 ) Other Carryforwards Canada 21,682 4,184 (4,184 ) None Other foreign 2,846 967 (967 ) 2016-2022 24,528 5,151 (5,151 ) $ 61,922 $ 14,019 $ (13,719 ) The net change in the valuation allowance for the years ended December 31, 2015, 2014, and 2013, were increases of $11,219, $101, and $115, respectively. This valuation allowance is reviewed on a regular basis and adjustments made as appropriate. The increase in the valuation allowance in 2015 reflects NOL and other carryforwards related to the Silanis acquisition further described in Note 4. The change in the valuation allowance also reflects other factors including, but not limited to, changes in our assessment of our ability to use existing NOLs and other deduction carryforwards, changes in currency rates, and adjustments to reflect differences between the actual returns filed and the estimates we made at financial reporting dates. The company expects to generate adequate taxable income to realize deferred tax assets in foreign jurisdictions where no valuation allowance exists. We had no accrued interest or penalties for income tax liabilities at December 31, 2015. Our policy is to record interest expense and penalties on income taxes as income tax expense.

We include various types of indemnification clauses in our agreements. These indemnifications may include, but are not limited to, infringement claims related to our intellectual property, direct damages and consequential damages. The type and amount of such indemnifications vary substantially based on our assessment of risk and reward associated with each agreement. We believe the estimated fair value of these indemnification clauses is minimal and there have been no previous indemnification claims, and we cannot determine the maximum amount of potential future payments, if any, related to such indemnification provisions. We have no liabilities recorded for these clauses as of December 31, 2015. During the second quarter of 2015, our management became aware that certain of our products which were sold by our European subsidiary to a third-party distributor may have been resold by the distributor to parties in Iran, potentially including parties whose property and interests in property may be blocked pursuant to Executive Order 13224, Executive Order 13382 or that may be identified under Section 560.304 of 31 C.F.R. Part 560 as the “Government of Iran”. We ceased shipping to such distributor. In addition, the Audit Committee of the Company’s Board of Directors initiated an internal review of this matter with the assistance of outside counsel. As a precautionary matter, concurrent initial notices of voluntary disclosure were submitted on June 25, 2015 to each of the U.S. Department of the Treasury, Office of Foreign Assets Control (“OFAC”), and the U.S. Department of Commerce, Bureau of Industry and Security (“BIS”). The Audit Committee with the assistance of outside counsel has completed their review. On December 15, 2015, we filed a letter with BIS (Office of Export Enforcement) with the conclusion that the products supplied to the distributor were not subject to United States Export Control jurisdiction. The Office of Export Enforcement issued a “no action” letter, concluding the voluntary self-disclosure process under the Export Administration Regulations. On January 13, 2016, we filed a letter with OFAC, with the conclusions that VASCO and its subsidiaries made no direct sales to Iran or any party listed by OFAC as a Specially Designated National over the five-year period under review (i.e., June 1, 2010 to June 30, 2015). The letter further noted that the investigation did not identify any involvement on the part of senior management officials of VASCO, and to the contrary, noted that VASCO executive management officials had sought to implement procedures and provided notices to VASCO’s sales personnel to prevent the diversion of VASCO products to unauthorized destinations and end users. We have not received any response to the letter to OFAC and we cannot predict when OFAC will conclude their review of our voluntary self-disclosures. Based upon the OFAC guidelines for monetary penalties, we have accrued $900 for potential penalties if they are assessed by OFAC. Ultimately no penalty may be assessed or the penalty may be less or greater than the accrual, but in any event we do not believe that the final settlement will have a material adverse impact on our business. On July 28, 2015 a putative class action complaint was filed in the United States District Court for the Northern District of Illinois, captioned Linda J. Rossbach v. Vasco Data Security International, Inc., et al., case number 1:15-cv-06605, naming VASCO and certain of its current executive officers as defendants and alleging violations under the Securities Exchange Act of 1934, as amended. The suit was purportedly filed on behalf of a putative class of investors who purchased VASCO securities between February 18, 2014 and July 21, 2015, and seeks to recover damages allegedly caused by the defendants’ alleged violations of the federal securities laws and to pursue remedies under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. The complaint seeks certification as a class action and unspecified compensatory damages plus interest and attorneys’ fees. Pursuant to a September 1, 2015 scheduling order entered by the court, the lead plaintiff, once appointed, will have sixty days to file an amended complaint or notify the defendants that the lead plaintiff intends to rely on the current complaint. The defendants will then have sixty days to answer or otherwise respond to the operative complaint. Although the ultimate outcome of litigation cannot be predicted with certainty, the Company believes that this lawsuit is without merit and intends to defend against the action vigorously. On October 9, 2015, a derivative complaint was filed in the United States District Court for the Northern District of Illinois, captioned Elizabeth Herrera v. Hunt, et al., case number 1:15-cv-08937, naming VASCO’s Board of Directors and certain of its executive officers as individual defendants and the Company as a nominal defendant. On February 23, 2016, the court in Herrera granted a stay of the action pending the resolution of a certain motion to dismiss that the parties anticipate will be filed in Rossbach. On October 22, 2015, a second derivative complaint was filed in the Circuit Court of Cook County, Illinois, captioned Beth Seltzer v. Hunt, et al., case number 2015-ch-15541, naming the same defendants. The complaints assert, among other things, that the individual defendants breached their fiduciary duties by making material misstatements in, and omitting material information from, the Company’s public disclosures and by failing to maintain adequate internal controls and properly manage the Company. Among other things, the complaints seek unspecified compensatory damages and injunctive relief. On October 29, 2015, a defendant removed the Seltzer action to the United States District Court for the Northern District of Illinois. Thereafter, the plaintiff led a motion to remand the action back to the Circuit Court of Cook County, Illinois, which was denied on February 3, 2016. On February 9, 2016, the court granted an agreed motion for voluntary dismissal of the Seltzer action, which dismissed the action with prejudice as to the named plaintiff’s individual claims. From time to time, we have been involved in litigation incidental to the conduct of our business. Excluding matters disclosed above, we are not a party to any lawsuit or proceeding that, in management’s opinion, is likely to have a material adverse effect on its business, financial condition or results of operations.

Summary of Significant Accoun23

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations VASCO Data Security International, Inc. and its wholly owned subsidiaries design, develop, market and support hardware and software security systems that manage and secure access to information assets. VASCO has operations in Austria, Australia, Belgium, Brazil, China, France, India, Japan, The Netherlands, Singapore, Switzerland, the United Arab Emirates, the United Kingdom (U.K)., and the United States (U.S.).
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of VASCO Data Security International, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. As further described in Note 3, during January 2011 we acquired 100% of the stock of DigiNotar B.V. Effective September 20, 2011, DigiNotar B.V. was declared bankrupt in The Netherlands, transferring effective control over DigiNotar B.V. to the bankruptcy trustee. Accordingly, assets, liabilities and operating activities related to DigiNotar B.V. are reflected as discontinued operations.
Estimates and Assumptions	Estimates and Assumptions The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions The financial position and results of the operations of the majority of the company’s foreign subsidiaries are measured using the local currency as the functional currency. Accordingly, assets and liabilities are translated into U.S. Dollars using current exchange rates as of the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing during the year. Translation adjustments arising from differences in exchange rates are charged or credited to other comprehensive income. Losses resulting from foreign currency transactions were $1,247, $1,382, and $624 in 2015, 2014, and 2013, respectively, and are included in other income (expense) in the consolidated statements of operations. The financial position and results of our operations in Canada, Singapore, and Switzerland are measured in U.S. Dollars. For these subsidiaries, gains and losses that result from foreign currency transactions are included in the consolidated statements of operations in other income (expense).
Revenue Recognition	Revenue Recognition We recognize revenue in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605, Software – Revenue Recognition Revenue Recognition – Multiple Element Arrangements Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable. In multiple-element arrangements, some of our products are accounted for under the software provisions of ASC 985-605 and others under the provisions that relate to the sale of non-software products. In our typical multiple-element arrangement, the primary deliverables include: 1. a client component (i.e., an item that is used by the person being authenticated in the form of either a new standalone hardware device or software that is downloaded onto a device the customer already owns), 2. host system software that is installed on the customer’s systems (i.e., software on the host system that verifies the identity of the person being authenticated) or licenses for additional users on the host system software if the host system software had been installed previously, and 3. post contract support (“PCS”) in the form of maintenance on the host system software or support. Our multiple-element arrangements may also include other items that are usually delivered prior to the recognition of any revenue and incidental to the overall transaction such as initialization of the hardware device, customization of the hardware device itself or the packaging in which it is delivered, deployment services where we deliver the device to our customer’s end-use customer or employee and, in some limited cases, professional services to assist with the initial implementation of a new customer. In multiple-element arrangements that include a hardware client device, we allocate the selling price among all elements, delivered and undelivered, based on our internal price lists and the percentage of the selling price of that element, per the price list, to the total of the estimated selling price of all of the elements per the price list. Our internal price lists for both delivered and undelivered elements were determined to be reasonable estimates of the selling price of each element based on a comparison of actual sales made to the price list for each item delivered and to vendor specific objective evidence (VSOE) for undelivered items. Undelivered elements primarily are PCS. The method by which we determine VSOE has validated that the price lists are reasonable estimates of the selling price for PCS. The estimated selling price of PCS items is based on an established percentage of the user license fee attributable to the specific software and is applied consistently to all PCS arrangements. The percentage we use to establish VSOE, which is also generally consistent with the percentage used in the price list, is developed using the “bell curve method”. Under this method, we conclude VSOE exists when a substantial majority of PCS renewals are within a narrow range of pricing. In multiple-element arrangements that include a software client device, we account for each element under the standards of ASC 985-605 related to software. When software client devices and host software are delivered elements, we use the Residual Method (ASC 605-25) for determining the amount of revenue to recognize for token and software licenses if we have VSOE for all of the undelivered elements. Any discount provided to the customer is applied fully to the delivered elements in such an arrangement. VSOE of fair value of PCS agreements is based on customer renewal transactions on a worldwide basis. In sales arrangements where VSOE of fair value has not been established, revenue for all elements is deferred and amortized over the life of the arrangement. For transactions other than multiple-element arrangements, we recognize revenue as follows: 1. Hardware Revenue and License Fees: 2. Maintenance and Support Agreements: 3. Services: 4. Consulting and Education Services: We recognize revenue from sales to distributors and resellers on the same basis as sales made directly to customers. We recognize revenue when there is persuasive evidence that an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the revenue is probable. For large-volume transactions, we may negotiate a specific price that is based on the number of users of the software license or quantities of hardware supplied. The per unit prices for large-volume transactions are generally lower than transactions for smaller quantities and the price differences are commonly referred to as volume-purchase discounts. All revenue is reported on a net basis, excluding any sales or value added taxes.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are stated at cost plus accrued interest, which approximates fair value. Cash equivalents are high-quality short term money market instruments and commercial paper with maturities at acquisition of three months or less. Cash and cash equivalents are held by a number of U.S. and non-U.S. commercial banks and money market investment funds.
Short Term Investments	Short Term Investments Short term investments are stated at cost plus accrued interest, which approximates fair value. Short term investments are high-quality commercial paper and bank certificates of deposit with maturities at acquisition of more than three months and less than twelve months.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The credit worthiness of customers is reviewed prior to shipment. A reasonable assurance of collection is a requirement for revenue recognition. Verification of credit and/or the establishment of credit limits are part of the customer contract administration process. Credit limit adjustments for existing customers may result from the periodic review of outstanding accounts receivable. The company records trade accounts receivable at invoice values, which are generally equal to fair value. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments for goods and services. We analyze accounts receivable balances, customer credit-worthiness, current economic trends and changes in our customer payment timing when evaluating the adequacy of the allowance for doubtful accounts. The allowance is based on a specific review of all significant past-due accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.
Inventories	Inventories Inventories, consisting principally of hardware and component parts, are stated at the lower of cost or market. Cost is determined using the first-in-first-out (FIFO) method. We write down inventory where it appears that the carrying cost of the inventory may not be recovered through subsequent sale of the inventory. We analyze the quantity of inventory on hand, the quantity sold in the past year, the anticipated sales volume in the form of sales to new customers as well as sales to previous customers, the expected sales price and the cost of making the sale when evaluating the valuation of our inventory. If the sales volume or sales price of a specific model declines significantly, additional write downs may be required.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets ranging from three to seven years. Additions and improvements are capitalized, while expenditures for maintenance and repairs are charged to operations as incurred. Gains or losses resulting from sales or retirements are recorded as incurred, at which time related costs and accumulated depreciation are removed from the accounts.
Research and Development Costs	Research and Development Costs Costs for research and development, principally the design and development of hardware, and the design and development of software prior to the determination of technological feasibility, are expensed as incurred on a project-by-project basis.
Software Development Costs	Software Development Costs We capitalize software development costs in accordance with ASC 985-20, Costs of Software to be Sold, Leased, or Marketed.
Income Taxes	Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We recognize the effect of a change in tax rates on deferred tax assets and liabilities and in income in the period that includes the enactment date. We monitor our potential income tax exposures as required by ASC 740, Income Taxes We have significant net operating loss and other deductible carryforwards in certain jurisdictions available to reduce the liability on future taxable income. A valuation allowance has been provided to offset some of these future benefits because we have not determined that their realization is more likely than not.
Fair Value of Financial Instruments	Fair Value of Financial Instruments At December 31, 2015, and 2014, our financial instruments were cash equivalents, short term investments, accounts receivable, accounts payable and accrued liabilities. The estimated fair value of our financial instruments has been determined by using available market information and appropriate valuation methodologies, as defined in ASC 820, Fair Value Measurements.
Accounting for Leases	Accounting for Leases All of our leases are operating leases. Rent expense on facility leases is charged evenly over the life of the lease, regardless of the timing of actual payments.
Goodwill and Other Intangibles	Goodwill and Other Intangibles We account for goodwill and intangible assets in accordance with ASC 350 Intangibles – Goodwill and Other We assess the impairment of goodwill each November or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment review include significant underperformance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or the strategy for our overall business, and significant negative industry or economic trends. In accordance with ASC 350, we consider the company to be one reporting unit. Fair value is determined using a market approach using our stock price which is a level 1 valuation, as defined by ASC 820, Fair Value Measurements
Stock-Based Compensation	Stock-Based Compensation We have stock-based employee compensation plans, which are described more fully in Note 9. ASC 718, Compensation-Stock Compensation
Warranty	Warranty Warranties are provided on the sale of certain of our products and an accrual for estimated future claims is recorded at the time revenue is recognized. We estimate the cost based on past claims experience, sales history and other considerations. We regularly assess the adequacy of our estimates and adjust the amounts as necessary. Our standard practice is to provide a warranty on our hardware products for either a one or two year period after the date of purchase. Customers may purchase extended warranties covering periods from one to four years after the standard warranty period. We defer the revenue associated with the extended warranty and recognize it into income on a straight-line basis over the extended warranty period. We have historically experienced minimal actual claims over the warranty period.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ASU 2014-9 is effective for annual periods beginning after December 15, 2016, and interim periods within such annual periods, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers We are currently evaluating the impact of our pending adoption of ASU 2014-09 and ASU 2015-14 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard and whether we will elect early adoption.
