Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies
	TASER International, Inc. (“TASER” or the “Company”) is a developer and manufacturer of advanced conducted electrical weapons (“CEWs”) designed for use for use by law enforcement, military, corrections, and private security personnel and by private individuals for personal defense. In addition, the Company has developed full technology solutions for the capture, storage and management of video/audio evidence as well as other tactical capabilities for use in law enforcement. The Company sells its products worldwide through its direct sales force, distribution partners, online store and third-party resellers. The Company was incorporated in Arizona in September 1993, and reincorporated in Delaware in January 2001. The Company’s corporate headquarters and manufacturing facilities are located in Scottsdale, Arizona. The Company’s software development unit facility is located in Seattle, Washington.
	The accompanying consolidated financial statements include the accounts of the Company, and its wholly owned subsidiaries, including TASER International Europe SE (“TASER Europe”). TASER Europe was established in 2009 to facilitate sales and provide customer service to our customers in the European region. All material intercompany accounts, transactions, and profits have been eliminated.
	In 2014, the Company established TASER International, B.V. located in Amsterdam, the Netherlands, that will serve as its international headquarters. No transactions were recorded within TASER International, B.V. during the year ended December 31, 2014.
	a. Basis of Presentation and Use of Estimates
	The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S. of America (“U.S. GAAP”). The preparation of these consolidated financial statements 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions in these consolidated financial statements include:


	•	product warranty reserves,

	•	inventory valuation reserves,

	•	revenue recognition allocated in multiple-deliverable contracts or arrangements,

	•	valuation of goodwill, intangibles and long-lived assets,

	•	recognition, measurement and valuation of current and deferred income taxes,

	•	fair value of stock awards issued, the estimated vesting period for performance-based stock awards and forfeiture rates, and

	•	recognition and measurement of contingencies and accrued litigation expense.
	Actual results could differ materially from those estimates.
	b. Cash, Cash Equivalents and Investments
	Cash, cash equivalents and investments include cash, money market funds, certificates of deposit, state and municipal obligations and corporate bonds. The Company places its cash and cash equivalents with high quality financial institutions. Balances with these institutions regularly exceed FDIC insured limits; however, to manage the related credit exposure, the Company continually monitors the creditworthiness of the financial institutions where it has deposits.
	Cash and cash equivalents include funds on hand and highly liquid investments purchased with initial maturity of three months or less. Short-term investments include securities with an expected maturity date within one year of the balance sheet date that do not meet the definition of a cash equivalent, and long-term investments are securities with an expected maturity date greater than one year. Based on management’s intent and ability, the Company’s investments are classified as held to maturity investments and are recorded at amortized cost. Held-to-maturity investments are reviewed quarterly for impairment to determine if other-than-temporary declines in the carrying value have occurred for any individual investment. Other-than-temporary declines in the value of held-to-maturity investments are recorded as expense in the period the determination is made.

	c. Inventory
	Inventories are stated at the lower of cost or market. Cost is determined using the weighted average cost of raw materials which approximates the first-in, first-out (“FIFO”) method and includes allocations of manufacturing labor and overhead. Provisions are made to reduce potentially excess, obsolete or slow-moving inventories to their net realizable value. These provisions are based on management’s best estimate after considering historical demand, projected future demand, inventory purchase commitments, industry and market trends and conditions and other factors. Management evaluates inventory costs for abnormal costs due to excess production capacity and treats such costs as period costs.
	d. Property and Equipment
	Property and equipment are stated at cost, net of accumulated depreciation and amortization. Additions and improvements are capitalized, while ordinary maintenance and repair expenditures are charged to expense as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets.
	e. Software Development Costs

	The Company expenses software development costs, including costs to develop software products or the software component of products to be marketed to external users, before technological feasibility of such products is reached. The Company has determined that technological feasibility is reached shortly before the release of those products and as a result, the development costs incurred after the establishment of technological feasibility and before the release of those products are not material.

	Software development costs also include costs to develop software programs to be used solely to meet the Company's internal needs and cloud based applications used to deliver its services. The Company capitalizes development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the intended function. Additionally, the Company capitalizes qualifying costs incurred for upgrades and enhancements to existing software that result in additional functionality. Costs related to preliminary project planning activities, post-implementation activities, maintenance and minor modifications are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life. There were no software development costs capitalized for the years ending December 31, 2014, 2013 or 2012. The capitalized development costs related to the Company’s software-as-a-service (“SaaS”) product, EVIDENCE.com, were fully amortized as of December 31, 2013. Amortization of capitalized software development costs was $0.6 million and $1.2 million for the years ended December 31, 2013 and 2012, respectively.
	Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
	f. Valuation of Goodwill, Intangibles and Long-lived Assets
	In the fourth quarter of 2013, the Company recorded goodwill related to the acquisition of Familiar, Inc. ("Familiar"). The recoverability of goodwill is evaluated and tested for impairment at least annually during the fourth quarter or more often, if and when circumstances indicate that goodwill may not be recoverable. Finite-lived intangible assets and other long-lived assets are amortized over their useful lives. Management evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and intangible assets may warrant revision or that the remaining balance of these assets, including intangible assets with indefinite lives, may not be recoverable.
	Circumstances that might indicate long-lived assets might not be recoverable could include, but are not limited to, a change in the product mix, a change in the way products are created, produced or delivered, or a significant change in the way the Company's products are branded and marketed. When performing a review for recoverability, management estimates the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The amount of the impairment loss, if impairment exists, is calculated based on the excess of the carrying amounts of the assets over their estimated fair value computed using discounted cash flows. No impairment losses were recorded during the years ended December 31, 2014, 2013 and 2012.
	g. Customer Deposits
	The Company requires deposits in advance of shipment for certain customer sales orders. Customer deposits are recorded as a current liability in the accompanying consolidated balance sheets.
	h. Revenue Recognition, Deferred Revenue and Accounts and Notes Receivable
	The Company derives revenue from two primary sources: (1) the sale of physical products, including our CEWs, AXON cameras, corresponding extended warranties, and related accessories such as cartridges and batteries, and (2) subscription to the Company's EVIDENCE.com SaaS (including data storage fees and other ancillary services), which includes varying levels of support. To a lesser extent, the Company also recognizes training and other revenue. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, title has transferred, the price is fixed and collectability is reasonably assured. Extended warranty revenue, SaaS revenue and related data storage revenue are recognized ratably over the term of the contract beginning on the commencement date of each contract.
	Revenue arrangements with multiple deliverables are divided into separate units and revenue is allocated using the relative selling price method based upon vendor-specific objective evidence of selling price or third-party evidence of the selling prices if vendor-specific objective evidence of selling prices does not exist. If neither vendor-specific objective evidence nor third-party evidence exists, management uses its best estimate of selling price.
	The Company offers the right to purchase extended warranties that include additional services and coverage beyond the limited warranty for certain products. Revenue for extended warranty purchases is deferred at the time of sale and recognized over the warranty period commencing on the date of sale. Extended warranties range from one to five years.
	EVIDENCE.com and AXON cameras are sometimes sold separately, but in most instances are sold together. In these instances, customers typically purchase and pay for the equipment and one year of EVIDENCE.com in advance. Additional years of service are generally billed annually over a specified service term, which has typically ranged from one to five years. AXON equipment has stand-alone value and represents a deliverable that is provided to the customer at the time of sale, while EVIDENCE.com services are provided over the specified term of the contract. The Company recognizes revenue for the AXON equipment at the time of the sale consistent with the discussion of multiple deliverable arrangements above. Revenue for EVIDENCE.com is deferred at the time of the sale and recognized over the service period. In certain circumstances, not all requirements are met for the recognition of revenue relative to equipment sold in conjunction with EVIDENCE.com at the time the equipment is provided to customers. In such circumstances, based on limitations associated with the allocation of arrangement consideration, part of the revenue may be recognized ratably over the specified term of the contract, or when all conditions for revenue recognition are met, if sooner.
	In 2012, the Company introduced a program, the TASER Assurance Program (“TAP”) whereby a customer purchasing a product and joining the program will have the right to trade-in the original product for a new product of the same or like model in the future. Upon joining TAP, customers also receive an extended warranty for the initial products purchased and spare inventory. Under this program the customer generally pays additional annual installments over the contract period, generally three to five years. The Company records consideration received related to the future product purchase as deferred revenue until all revenue recognition criteria are met, which is generally at the end of the contract period.
	Sales tax collected on sales is netted against government remittances and thus, recorded on a net basis. Training revenue is recorded as the service is provided.
	Deferred revenue consists of payments received in advance related to products and services for which the criteria for revenue recognition have not yet been met. Deferred revenue that will be recognized during the succeeding twelve month period is recorded as current deferred revenue and the remaining portion is recorded as long-term. Deferred revenue does not include future revenue from multi-year contracts for which no invoice has yet been created. Generally, customers are billed in annual installments. See Note 7 for further disclosures about of the Company’s deferred revenue.
	Sales are typically made on credit and the Company generally does not require collateral. Management performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for estimated potential losses. Uncollectible accounts are charged to expense when deemed uncollectible, and accounts and notes receivable are presented net of an allowance for doubtful accounts. This allowance represents management’s best estimate and is based on their judgment after considering a number of factors, including third-party credit reports, actual payment history, cash discounts, customer-specific financial information and broader market and economic trends and conditions.

	The Company may, from time to time, enter into agreements with its customers to finance their purchases with a note receivable that may range in terms up to five years. Sales are recorded at the fair value of the note, which is generally sold and assigned to a third-party financing company. The terms of the assignments are such that the Company expects to receive payment within 30 days of the original sale. The assignments are non-recourse and the Company has no obligations or continuing involvement with the notes receivable. Prior to entering into an assignment, the Company evaluates the credit quality and financial condition of the third-party financing company. The Company does not generally record interest income on notes receivable due to minimal holding periods, nor has the Company recognized gains or losses upon the assignment of the notes. As of December 31, 2014 and 2013, there was no balance in accounts and notes receivable related to such arrangements.
	i. Cost of Products Sold and Services Provided
	Cost of products sold represents manufacturing costs, consisting of materials, labor and overhead related to finished goods and components. Shipping costs incurred related to product delivery are also included in cost of products sold. Cost of services delivered includes third party cloud services, and software maintenance costs, including personnel costs, associated with supporting EVIDENCE.com.
	j. Advertising Costs
	The Company expenses advertising costs in the period in which they are incurred. The Company incurred advertising costs of $0.3 million, $0.2 million and $0.2 million in the years ended December 31, 2014, 2013 and 2012, respectively. Advertising costs are included in sales, general and administrative expenses in the accompanying statements of operations.
	k. Standard Warranties
	The Company warranties its CEWs, AXON cameras and E-Docks from manufacturing defects on a limited basis for a period of one year after purchase and, thereafter, will replace any defective unit for a fee. Estimated costs for the standard warranty are charged to cost of products sold and services delivered when revenue is recorded for the related product. Future warranty costs are estimated based on historical data related to returns and warranty costs on a quarterly basis and this rate is applied to current product sales. Historically, reserve amounts have been increased if management becomes aware of a component failure that could result in larger than anticipated returns from customers. The accrued warranty liability expense is reviewed quarterly to verify that it sufficiently reflects the remaining warranty obligations based on the anticipated expenditures over the balance of the warranty obligation period, and adjustments are made when actual warranty claim experience differs from estimates. Costs related to extended warranties are charged to cost of products sold and services delivered when incurred. The reserve for warranty returns is included in accrued liabilities on the accompanying consolidated balance sheets.
	Changes in the Company’s estimated product warranty liabilities are as follows (in thousands):


		2014			2013				2012
	Balance, January 1	$	955		$	484			$	427
	Balance, January 1	$	955		$	484			$	427

Balance, December 31	$	675		$	955			$	484
Balance, December 31	$	675		$	955			$	484

l. Research and Development Expenses
The Company expenses as incurred research and development costs that do not meet the qualifications to be capitalized. The Company incurred research and development expense of $14.9 million, $9.9 million and $8.1 million, in 2014, 2013 and 2012, respectively.
m. Income Taxes
Income taxes are accounted for 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 amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in future years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced through the establishment of a valuation allowance if, based upon available evidence, it is determined that it is more likely than not that the deferred tax assets will not be realized.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. Management also assesses whether uncertain tax positions, as filed, could result in the recognition of a liability for possible interest and penalties. The Company’s policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense. Refer to Note 10 for additional information regarding the change in unrecognized tax benefits.
n. Concentration of Credit Risk and Major Customers / Suppliers
Financial instruments that potentially subject the Company to concentrations of credit risk consist of accounts and notes receivable and cash. Sales are typically made on credit and the Company generally does not require collateral. Management performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for estimated losses. Uncollectible accounts are written off when deemed uncollectible, and accounts receivable are presented net of an allowance for doubtful accounts, which totaled $0.3 million and $0.2 million as of December 31, 2014 and 2013, respectively. Historically, the Company has experienced a low level of write-offs related to doubtful accounts.
The Company maintains the majority of its cash and cash equivalents accounts at three depository institutions. As of December 31, 2014, the aggregate balances in such accounts were $48.4 million. The Company’s cash balances with these institutions regularly exceed FDIC insured limits; however, to manage the related credit exposure, management continually monitors the creditworthiness of the financial institutions where the Company has deposits.
The Company sells its products primarily through a network of unaffiliated distributors. The Company also reserves the right to sell directly to the end user to secure the customer’s account. In 2014, no customer represented more than 10% of total net sales. In 2013 and 2012 one distributor represented 12.2% and 12.8%, respectively, of total net sales with no other customers exceeding 10%.
At December 31, 2014, the Company had a trade receivable from one unaffiliated customer comprising 13.4% of the aggregate accounts receivable balance. At December 31, 2013, the Company had a trade receivable from one unaffiliated customer comprising 17.4% of the aggregate accounts receivable balance.
The Company currently purchases finished circuit boards and injection-molded plastic components from suppliers located in the U.S. Although the Company currently obtains many of these components from single source suppliers, the Company owns the injection molded component tooling used in their production. As a result, management believes it could obtain alternative suppliers in most cases without incurring significant production delays. The Company also purchases small, machined parts from a vendor in Taiwan, custom cartridge assemblies from a proprietary vendor in the U.S., and electronic components from a variety of foreign and domestic distributors. Management believes that there are readily available alternative suppliers in most cases who can consistently meet the Company's needs for these components. The Company acquires most of its components on a purchase order basis and does not have long-term contracts with suppliers.

o. Fair Value of Financial Instruments
The Company uses the fair value framework that prioritizes the inputs to valuation techniques for measuring financial assets and liabilities measured on a recurring basis and for non-financial assets and liabilities when these items are re-measured. Fair value is considered to be the exchange price in an orderly transaction between market participants, to sell an asset or transfer a liability at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:


•	Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

•	Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

•	Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Company's own assumptions about inputs that market participants would use in pricing an asset or liability.
The Company has cash equivalents and investments, which at December 31, 2014 and 2013, were comprised of money market funds, state and municipal obligations, corporate bonds, and certificates of deposits. See additional disclosure regarding the fair value of the Company’s cash equivalents and investments in Note 2. Included in the balance of other assets as of December 31, 2014 and 2013 was $1.1 million and $0.4 million, respectively, related to corporate-owned life insurance policies which are used to fund the Company’s deferred compensation plan. The Company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer, a Level 2 valuation technique.
The Company’s financial instruments also include accounts and notes receivable, accounts payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the balance sheet.
p. Segment and Geographic Information
The Company is comprised of two reportable segments: the sale of CEWs, accessories and other products and services (the “TASER Weapons” segment); and the video business which includes the TASER Cam, AXON camera products and EVIDENCE.com (the “AXON” segment). Reportable segments are determined based on discrete financial information reviewed by the Company’s Chief Executive Officer who is the Chief Operating Decision Maker (the “CODM”) for the Company. The Company organizes and reviews operations based on products and services, and currently there are no operating segments that are aggregated. The Company performs an annual analysis of its reportable segments. Additional information related to the Company’s business segments is summarized in Note 15.

For the three years ended December 31, 2014, 2013 and 2012, net sales by geographic area were as follows (in thousands):


	Year Ended December 31,
	2014						2013						2012

Total	$	164,525		100	%		$	137,831			100	%	$	114,753	100	%

Sales to customers outside of the U.S. are typically denominated in U.S. dollars and are attributed to each country based on the shipping address of the distributor or customer. For the three years ended December 31, 2014, 2013 and 2012, no individual country outside the U.S. represented more than 10% of net sales. Substantially all of the Company’s assets are located in the U.S.
q. Stock-Based Compensation
The Company calculates the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock units is estimated as the closing price of our common stock on the date of grant. No options were awarded during the years ended December 31, 2014, 2013 or 2012.
The expected life of the options represents the estimated period of time from grant date until exercise and is based on historical experience of similar awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. Expected stock price volatility is based on a combination of historical volatility of the Company’s stock and the one-year implied volatility of its publicly traded options for the related vesting periods. The risk-free interest rate is based on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term. The Company has not paid dividends in the past and does not plan to pay any dividends in the near future.
The estimated fair value of stock-based compensation awards is amortized to expense on a straight-line basis over the requisite service periods. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company’s forfeiture rate was calculated based on its historical experience of awards which ultimately vested. See Note 12 for further disclosure about of the Company’s stock-based compensation.

r. Income per Common Share
Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted income per share reflects the potential dilution that would occur if outstanding stock options were exercised utilizing the treasury stock method. The calculation of the weighted average number of shares outstanding and earnings per share are as follows (in thousands except per share data):

s. Recently Issued Accounting Guidance

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation—Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (i) prospectively to all awards granted or modified after the effective date; or (ii) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company is currently evaluating the potential impact of the adoption of this guidance on its consolidated financial statements, however does not expect there to be a material impact at this time.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, ASU 2014-09 provides for the following steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification Topic No. 605, “Revenue Recognition,” most industry-specific guidance throughout the industry topics of the Accounting Standards Codification, and some cost guidance related to construction-type and production-type contracts. ASU 2014-09 is effective for public entities for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company is currently evaluating the potential impact of the adoption of this guidance on its consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11 to standardize the balance sheet presentation of unrecognized tax benefits. This update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The new guidance was effective for fiscal years beginning after December 15, 2013. The adoption of this guidance resulted in an immaterial reclassification on the Company’s consolidated balance sheet.

t. Foreign Currency Translation
The Company’s foreign subsidiary uses the local currency as its functional currency. Assets and liabilities are translated at exchange rates in effect at the balance sheet date. Income and expense accounts are translated at the average monthly exchange rates during the year. Resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss) on the consolidated balance sheets.

u. Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations.

	The Company believes the unrealized losses on the Company’s investments are due to interest rate fluctuations. As these investments are either short-term in nature, are expected to be redeemed at par value and/or because the Company has the ability and intent to hold these investments to maturity, the Company does not consider these investments to be other than temporarily impaired at December 31, 2014. None of Company’s investments have been in an unrealized loss position for more than one year.

b. Purchase commitments

The Company routinely enters into cancelable purchase orders with many of its key vendors. Based on the strategic relationships with many of these vendors, the Company’s ability to cancel these purchase orders and maintain a favorable relationship would be limited. As of December 31, 2014, the Company has $19.1 million of open purchase orders.

c. Litigation

Product Litigation

The Company is currently named as a defendant in 12 lawsuits in which the plaintiffs allege either wrongful death or personal injury in situations in which a TASER CEW was used (or present) by law enforcement officers in connection with arrests or during training exercises. In addition, two other product litigation matters in which the Company is involved are currently on appeal. While the facts vary from case to case, the product liability claims are typically based on an alleged product defect resulting in injury or death, usually involving a failure to warn, and the plaintiffs are seeking monetary damages.

As a general rule, it is the Company’s policy not to settle suspect injury or death cases. Exceptions are sometimes made where the settlement is strategically beneficial to the Company. Also, on occasion, the Company’s insurance company has settled such lawsuits over the Company’s objection where the risk is over the Company’s liability insurance deductibles. Due to the confidentiality of our litigation strategy and the confidentiality agreements that are executed in the event of a settlement, the Company does not identify or comment on which specific lawsuits have been settled or the amount of any settlement.

In 2009, the Company implemented new risk management strategies, including revisions to product warnings and training to better protect both the Company and its customers from litigation based on ‘failure to warn’ theories – which comprise the vast majority of the cases against the Company. These risk management strategies have been highly effective in reducing the rate and exposure from litigation post-2009. From the third quarter of 2011 to the fourth quarter of 2014, product liability cases have been reduced from 55 active to 12 active cases, with two new lawsuits filed in the fourth quarter of 2014.

Management believes that pre-2009 cases have a different risk profile than cases which have occurred since the risk management procedures were introduced in 2009. Therefore, the Company necessarily treats certain pre-2009 cases as exceptions to the Company’s general no settlement policy in order to reduce caseload, legal costs and liability exposure. The Company intends to continue its successful practice of aggressively defending and generally not settling litigation except in very limited and unusual circumstances as described above.

With respect to each of the pending lawsuits, the following table lists the name of plaintiff, the date the Company was served with process, the jurisdiction in which the case is pending, the type of claim and the status of the matter.

General

From time to time, the Company is notified that it may be a party to a lawsuit or that a claim is being made against it. It is the Company’s policy to not disclose the specifics of any claim or threatened lawsuit until the summons and complaint are actually served on the Company. After carefully assessing the claim, and assuming we determine that we are not at fault or we disagree with the damages or relief demanded, we vigorously defend any lawsuit filed against the Company. In certain legal matters, we record a liability when losses are deemed probable and reasonably estimable. In evaluating matters for accrual and disclosure purposes, we take into consideration factors such as our historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood of our prevailing, and the severity of any potential loss. We reevaluate and update our accruals as matters progress over time.

Based on our assessment of outstanding litigation and claims as of December 31, 2014, the Company has determined that it is not reasonably possible that these lawsuits will individually, or in the aggregate, materially affect our results of operations, financial condition or cash flows. However, the outcome of any litigation is inherently uncertain and there can be no assurance that any expense, liability or damages that may ultimately result from the resolution of these matters will be covered by our insurance or will not be in excess of amounts recognized or provided by insurance coverage and will not have a material adverse effect on our operating results, financial condition or cash flows.

d. Employment Agreements

The Company has employment agreements with certain key executives. The Company may terminate the agreements with or without cause. Should the Company terminate the agreements without cause, or upon a change of control of the Company or death or disability of the employee, the employee, or family of the employee, are entitled to additional compensation. Under these circumstances, these officers and employees would receive the amounts remaining under their contracts upon termination, which total approximately $1.0 million in the aggregate at December 31, 2014. In March 2015, the Company finalized its severance agreement with a former executive whose position was eliminated in 2014, and accordingly, the Company accrued approximately $0.5 million as of December 31, 2014.

	The Company’s net deferred tax assets are presented as follows on the accompanying consolidated balance sheets at December 31 (in thousands):


		2014				2013
	Current deferred tax assets, net	$	5,186			$	7,101

	Long-term deferred tax assets, net	10,877				13,679

	Total	$	16,063			$	20,780


	For the years ended December 31, 2014, 2013 and 2012 the provision for income taxes includes $8.0 million, $6.8 million and $4.7 million, respectively, of tax expense resulting from the fact that stock-based compensation tax benefits have been recorded as increases to additional paid-in capital on the consolidated statement of changes in stockholders’ equity.
	The Company has deferred tax assets of $0.1 million related to state NOLs which expire at various dates between 2016 and 2031. The Company also has deferred tax assets of approximately $0.2 million related to federal NOLs which expire between 2031 and 2033, and are subject to limitation under IRC Section 382. The Company has Arizona R&D credit carry forwards for financial reporting purposes of $3.2 million, which expire at various dates between 2018 and 2028, and California R&D credit carry forwards for financial reporting purposes of $0.2 million which do not expire. The Company has a minimum tax credit carryover of $1.1 million which does not expire.
	The Company recognizes the income tax benefits associated with certain stock compensation deductions only when such deductions produce a reduction to the Company’s actual tax liability. Accordingly, in 2014 and 2013, the Company recognized benefits of $8.0 million and $6.8 million, respectively, for the reduction of federal and state taxes payable, which was recorded as a credit to additional paid-in capital. At each of December 31, 2014 and 2013, the Company had income tax receivables of $1.3 million and $2.3 million, respectively.

	In preparing the Company’s consolidated financial statements, management has assessed the likelihood that deferred income tax assets will be realized from future taxable income. In evaluating the ability to recover its deferred income tax assets, management considers all available evidence, positive and negative; including the Company’s operating results, ongoing tax planning and forecasts of future taxable income on a jurisdiction by jurisdiction basis. A valuation allowance is established if it is determined that it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. Management exercises significant judgment in determining the Company’s provisions for income taxes, its deferred income tax assets and liabilities and its future taxable income for purposes of assessing its ability to utilize any future tax benefit from its deferred income tax assets.

	Although management believes that its tax estimates are reasonable, the ultimate tax determination involves significant judgments that could become subject to audit by tax authorities in the ordinary course of business. As of each reporting date, management considers new evidence, both positive and negative, that could impact management’s view with regards to future realization of deferred tax assets. As of December 31, 2012, in part because in that year the Company achieved three years of cumulative pre-tax income in the U.S. federal and Arizona tax jurisdictions, management determined that sufficient positive evidence existed to conclude that it is more likely than not that additional deferred taxes related to Arizona R&D credits are realizable, and therefore, reversed in full the valuation allowance related to that item. As of December 31, 2014, the Company continues to demonstrate three-year cumulative pre-tax income in the U.S. federal and Arizona tax jurisdictions; however, the Arizona R&D Tax Credits start to expire in 2018 with a significant tranche with a gross value of $1.2 million expiring in 2019. Under the Company’s new tax structure, it appears that long term investments which impact short term profits will likely result in some of the R&D credits expiring before they are utilized. Therefore, management has concluded that it is more likely than not that a portion of the Company’s deferred tax assets will not be realized.
	Significant components of the provision for income taxes are as follows for the years ended December 31 (in thousands):


		2014				2013				2012
	Current:
	Federal	$	7,793			$	7,963			$	4,605

Tax provision recorded as an increase in liability for unrecorded tax benefits	202				219				920

Provision for income taxes	$	12,393			$	9,790			$	7,874


The Company is subject to federal, state, local and foreign taxes; however, no separate calculation of the foreign provision for deferred tax assets was calculated for the periods presented due to the minimal amount of book income in the Company’s foreign subsidiary and the comparability of the foreign tax rate to the tax rate in the U.S. A reconciliation of the Company’s effective income tax rate to the federal statutory rate for the years ended December 31, 2014, 2013 and 2012 is as follows (in thousands):


	2014				2013				2012

Effective tax rate	38.4		%		34.9		%		34.8		%


(i)	Permanent differences include certain expenses that are not deductible for tax purposes including lobbying fees as well as favorable items including the domestic production activities deduction

(ii)	The 2012 return to provision adjustment was driven by higher than estimated 2011 R&D tax credits which increased the net tax benefit and therefore, reduced the effective tax rate. The 2013 return to provision adjustment was driven by the domestic production activities deduction which decreased taxable income, and therefore, reduced the effective tax rate.
The Company has completed research and development tax credit studies which identified approximately $10.4 million in tax credits for federal, Arizona and California income tax purposes related to the 2003 through 2014 tax years. Management has made the determination that it is more likely than not that the full benefit of the R&D tax credit will not be sustained on examination and recorded a liability for unrecognized tax benefits of $3.1 million as of December 31, 2013. In addition, management accrued approximately $0.2 million for estimated uncertain tax positions related to certain state income tax liabilities. The Company is currently under an IRS audit for the tax year 2012. Depending on the outcome of the audit, the uncertain tax positions relating to 2012 may significantly change in the next 12 months. Should the unrecognized tax benefit of $3.3 million be recognized, the Company’s effective tax rate would be favorably impacted.
The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying Consolidated Statement of Operations. As of December 31, 2014 and 2013, respectively, the Company had accrued interest of $46,000 and $12,000.
The following table presents a roll forward of our liability for unrecognized tax benefits, exclusive of accrued interest, as of December 31 (in thousands):


	2014				2013				2012
Balance, beginning of period	$	3,110			$	2,903			$	1,982

Increase (decrease) related to adjustment of previous estimates of activity	94				6				111

Balance, end of period	$	3,325			$	3,110			$	2,903


Federal income tax returns for 2004 through 2013 remain open to examination by the U.S. Internal Revenue Service (the “IRS”), while state and local income tax returns for 2004 through 2013 also remain open to examination. The 2004 through 2009 income tax returns are only open to the extent that net operating loss or other tax attributes carrying forward from those years were utilized in 2010 through 2013. The foreign tax returns for 2011 through 2013 also remain open to examination. The Company is currently under examination by the IRS for tax year 2012. As of December 31, 2014 the exam is still ongoing. No adjustments have been proposed to date. The Company has not been notified by any major state tax jurisdiction that it will be subject to examination.

Line of Credit	12 Months Ended
Line of Credit	Dec. 31, 2014
Debt Disclosure [Abstract]
Line of Credit	Line of Credit
Line of Credit	The Company has a $10.0 million revolving line of credit with a domestic bank. At December 31, 2014 and 2013, there were no borrowings under the line. As of December 31, 2014, the Company had letters of credit outstanding of $0.4 million under the facility and available borrowing of $9.6 million. The line is secured by substantially all of the assets of the Company, and bears interest at varying rates (currently LIBOR plus 1.5% or Prime less 0.75%). The line of credit matures on July 31, 2016, and requires monthly payments of interest only. The Company’s agreement with the bank requires it to comply with certain financial and other covenants including maintenance of a minimum leverage ratio and fixed charge coverage ratio. The leverage ratio (ratio of total liabilities to tangible net worth) can be no greater than 1:1, and the fixed charge coverage ratio can be no less than 1.25:1, based upon a trailing twelve-month period. At December 31, 2014, the Company’s tangible net worth ratio was 0.45:1 and its fixed charge coverage ratio was 2.82:1. Accordingly, the Company was in compliance with these covenants.

Stockholders_Equity

Stockholders' Equity	12 Months Ended
	Dec. 31, 2014
Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity
	a. Common Stock and Preferred Stock
	The Company has authorized the issuance of two classes of stock designated as “common stock” and “preferred stock,” each having a par value of $0.00001 per share. The Company is authorized to issue 200 million shares of common stock and 25 million shares of preferred stock.
	b. Stock Repurchase

	In May 2014, the Company announced that TASER’s Board of Directors authorized a stock repurchase program to acquire up to $30.0 million of the Company’s outstanding common stock subject to stock market conditions and corporate considerations. Under this program, the Company purchased approximately 1.7 million common shares for a total cost of approximately $22.4 million, or a weighted average cost, including commissions of $12.99 per share. As of December 31, 2014, $7.6 million remains available under the plan for future purchases.
	In February 2013, the Company announced that TASER’s Board of Directors authorized a stock repurchase program to acquire up to $25 million of the Company’s outstanding common stock subject to stock market conditions and corporate considerations. Under this program, which was completed in the second quarter of 2013, the Company purchased approximately 3.0 million common shares for a total cost of approximately $25.0 million, or a weighted average cost, including commissions, of $8.20 per share.
	On April 25, 2012, TASER’s Board of Directors authorized a stock repurchase program to acquire up to $20.0 million of the Company’s outstanding common stock subject to stock market conditions and corporate considerations. The Company purchased approximately 3.8 million common shares under this program for a total cost of $20.0 million, or a weighted average cost, including commissions, of $5.22 per share. The buyback was completed in the third quarter of 2012.
	c. Stock-based Compensation Plans
	The Company has historically utilized stock-based compensation, consisting of restricted stock units (“RSUs”) and stock options, for key employees and non-employee directors as a means of attracting and retaining quality personnel. Service-based grants generally have a vesting period of 3 to 4 years and a contractual maturity of ten years. Performance-based grants generally have vesting periods ranging from 1 to 4 years and a contractual maturity of ten years.

	On February 25, 2013, the Company’s Board of Directors approved the 2013 Stock Incentive Plan (the “2013 Plan) which was subsequently approved by stockholders at the Annual Meeting of Stockholders on May 23, 2013. Under the 2013 Plan, the Company reserved for future grants: (i) 1.6 million shares of common stock, plus (ii) the number of shares of common stock that were authorized but unissued under the Company’s 2009 Stock Incentive Plan (the “2009 Plan”) as of the effective date of the 2013 Plan, and (iii) the number of shares of stock that have been granted under the 2009 Plan that either terminate, expire or lapse for any reason after the effective date of the 2013 Plan. As of December 31, 2014, 1.7 million shares remain available for future grants. Shares issued upon exercise of stock awards from these plans have historically been issued from the Company’s authorized unissued shares.
	d. Performance-based stock awards
	The Company has issued performance-based stock options and performance-based RSUs, the vesting of which is contingent upon the achievement of certain performance criteria related to the operating performance of the Company as well as successful and timely development and market acceptance of future product introductions. In addition, certain of the performance RSUs have additional service requirements subsequent to the achievement of the performance criteria. Compensation expense is recognized over the implicit service period (the longer of the period the performance condition is expected to be achieved or the required service period) based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date.
	e. Restricted Stock Units
	The following table summarizes RSU activity for the years ended December 31, 2014, 2013 and 2012:


		2014								2013						2012
		Number				Weighted				Number			Weighted			Number			Weighted
		of				Average				of			Average			of			Average

	Released	(432,706		)		7.61				(257,693	)		5.44			(97,007	)		5.3

	Forfeited	(174,657		)		13.08				(99,689	)		6.86			(35,025	)		5.29

	Units outstanding, end of year	1,226,088				13.23				1,279,123			9.67			582,212			5.42

	Aggregate intrinsic value at year end (in thousands)	$	32,467

	Aggregate intrinsic value represents the Company’s closing stock price on the last trading day of the period, which was $26.48 per share, multiplied by the number of restricted stock units. In 2014, 2013 and 2012, the Company granted approximately 0.1 million, 0.3 million and 0.2 million performance-based RSUs, respectively (included in the table above). As of December 31, 2014, the performance criteria has been met for approximately 0.1 million of the 0.2 million performance-based RSUs outstanding. The Company recognized $1.0 million, $1.4 million and $0.7 million of compensation expense related to performance-based RSUs during the years ended December 2014, 2013 and 2012, respectively.
	Certain RSUs that vested in 2014 were net-share settled such that the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. Total shares withheld were approximately 74,000 and had a value of approximately $1.3 million on their respective vesting dates as determined by the Company’s closing stock price. Payments for the employees’ tax obligations are reflected as a financing activity within the statement of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced the amount of shares that would have otherwise been issued as a result of the vesting.

	f. Stock Option Activity
	The following table summarizes stock option activity for the years ended December 31, 2014, 2013 and 2012:

	Options expected to vest, end of year	4,443			4.66

	No stock options were granted in 2014, 2013 or 2012. Total intrinsic value of options exercised was $20.2 million, $15.7 million and $3.2 million for the years ended December 31, 2014, 2013 and 2012, respectively. The intrinsic value for options exercised was calculated as the difference between the exercise price of the underlying stock option awards and the market price of the Company’s common stock on the date of exercise.
	The following table summarizes information about stock options outstanding and exercisable as of December 31, 2014:


	Options Outstanding									Options Exercisable

The aggregate intrinsic value of options outstanding and options exercisable at December 31, 2014, was $34.8 million and $34.1 million, respectively. Aggregate intrinsic value represents the difference between the exercise price of the underlying stock option awards and the closing market price of the Company’s common stock of $26.48 on December 31, 2014.
At December 31, 2014, the Company had 35,294 unvested options outstanding with a weighted average exercise price of $4.74 per share, weighted average fair value of $2.51 per share and weighted average remaining contractual life of 4.3 years. The aggregate intrinsic value of unvested options at December 31, 2014 was $0.8 million.
The Company granted approximately 1.0 million performance-based stock options (included in the table above) from 2008 through 2011. As of December 31, 2014, approximately 0.3 million performance-based stock options are outstanding, of which approximately 30,600 are unvested and none are expected to vest. The aggregate grant-date fair value of the 0.3 million performance-based stock options vested and expected to vest as of December 31, 2014 is approximately $0.8 million. Performance-based stock options were expensed in full as of December 31, 2013. The Company recognized $0.1 million of stock-based compensation expense related to performance-based stock options during each of 2013 and 2012.


g. Stock-based Compensation Expense
The Company accounts for stock-based compensation using the fair-value method. Reported stock-based compensation was classified as follows for the years ended December 31 (in thousands):

Pension and Other Postretirement Benefits Disclosure	Employee Benefit Plans
	The Company has a defined contribution profit sharing 401(k) plan for eligible employees, which is qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended. Employees are entitled to make tax-deferred contributions of up to the maximum allowed by law of their eligible compensation.
	The Company also has a non-qualified deferred compensation plan for certain executives, key employees and non-employee directors through which participants may elect to postpone the receipt and taxation of a portion of their compensation, including stock-based compensation, received from the Company. The non-qualified deferred compensation plan allows eligible participants to defer up to 80% of their base salary and up to 100% of other types of compensation. The plan also allows for (i) matching and discretionary employer contributions and (ii) the deferral of vested RSU awards. Employee deferrals are deemed 100% vested upon contribution. Distributions from the plan are made upon retirement, death, separation of service, specified date or upon the occurrence of an unforeseeable emergency. Distributions can be paid in a variety of forms from lump sum to installments over a period of years. Participants in the plan are entitled to select from a wide variety of investments available under the plan and are allocated gains or losses based upon the performance of the investments selected by the participant. All gains or losses are allocated fully to plan participants and the Company does not guarantee a rate of return on deferred balances. Assets related to this plan consist of corporate-owned life insurance contracts and are included in other assets in the consolidated balance sheets. Participants have no rights or claims with respect to any plan assets and any such assets are subject to the claims of the Company’s general creditors.
	Contributions to the plans are made by both the employee and the Company. Company contributions are based on the level of employee contributions and are immediately vested. The Company’s matching contributions to the plan for the years ended December 31, 2014, 2013 and 2012, were approximately $0.9 million, $0.7 million and $0.5 million, respectively. The Company expects to make contributions to the non-qualified deferred compensation plan related to the year ended December 31, 2014, of approximately $27,000. Future matching or profit sharing contributions to the plans are at the Company’s sole discretion.

Organization and Summary of Significant Accounting Policies (Policies)

Dec. 31, 2014

Accounting Policies [Abstract]

Basis of Presentation and Use of Estimates

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S. of America (“U.S. GAAP”). The preparation of these consolidated financial statements 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions in these consolidated financial statements include:

•

product warranty reserves,

•

inventory valuation reserves,

•

revenue recognition allocated in multiple-deliverable contracts or arrangements,

•

valuation of goodwill, intangibles and long-lived assets,

•

recognition, measurement and valuation of current and deferred income taxes,

•

fair value of stock awards issued, the estimated vesting period for performance-based stock awards and forfeiture rates, and

•

recognition and measurement of contingencies and accrued litigation expense.

Actual results could differ materially from those estimates.

Cash, Cash Equivalents and Investments

Cash, cash equivalents and investments include cash, money market funds, certificates of deposit, state and municipal obligations and corporate bonds. The Company places its cash and cash equivalents with high quality financial institutions. Balances with these institutions regularly exceed FDIC insured limits; however, to manage the related credit exposure, the Company continually monitors the creditworthiness of the financial institutions where it has deposits.

Cash and cash equivalents include funds on hand and highly liquid investments purchased with initial maturity of three months or less. Short-term investments include securities with an expected maturity date within one year of the balance sheet date that do not meet the definition of a cash equivalent, and long-term investments are securities with an expected maturity date greater than one year. Based on management’s intent and ability, the Company’s investments are classified as held to maturity investments and are recorded at amortized cost. Held-to-maturity investments are reviewed quarterly for impairment to determine if other-than-temporary declines in the carrying value have occurred for any individual investment. Other-than-temporary declines in the value of held-to-maturity investments are recorded as expense in the period the determination is made.

Inventory

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average cost of raw materials which approximates the first-in, first-out (“FIFO”) method and includes allocations of manufacturing labor and overhead. Provisions are made to reduce potentially excess, obsolete or slow-moving inventories to their net realizable value. These provisions are based on management’s best estimate after considering historical demand, projected future demand, inventory purchase commitments, industry and market trends and conditions and other factors. Management evaluates inventory costs for abnormal costs due to excess production capacity and treats such costs as period costs.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Additions and improvements are capitalized, while ordinary maintenance and repair expenditures are charged to expense as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets.

Software Development Costs

The Company expenses software development costs, including costs to develop software products or the software component of products to be marketed to external users, before technological feasibility of such products is reached. The Company has determined that technological feasibility is reached shortly before the release of those products and as a result, the development costs incurred after the establishment of technological feasibility and before the release of those products are not material.

Software development costs also include costs to develop software programs to be used solely to meet the Company's internal needs and cloud based applications used to deliver its services. The Company capitalizes development costs related to these software applications once the preliminary project stage is complete and it is probable that the project will be completed and the software will be used to perform the intended function. Additionally, the Company capitalizes qualifying costs incurred for upgrades and enhancements to existing software that result in additional functionality. Costs related to preliminary project planning activities, post-implementation activities, maintenance and minor modifications are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life. There were no software development costs capitalized for the years ending December 31, 2014, 2013 or 2012. The capitalized development costs related to the Company’s software-as-a-service (“SaaS”) product, EVIDENCE.com, were fully amortized as of December 31, 2013. Amortization of capitalized software development costs was $0.6 million and $1.2 million for the years ended December 31, 2013 and 2012, respectively.

Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

Valuation of Goodwill, Intangibles and Long-lived Assets

In the fourth quarter of 2013, the Company recorded goodwill related to the acquisition of Familiar, Inc. ("Familiar"). The recoverability of goodwill is evaluated and tested for impairment at least annually during the fourth quarter or more often, if and when circumstances indicate that goodwill may not be recoverable. Finite-lived intangible assets and other long-lived assets are amortized over their useful lives. Management evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and intangible assets may warrant revision or that the remaining balance of these assets, including intangible assets with indefinite lives, may not be recoverable.

Circumstances that might indicate long-lived assets might not be recoverable could include, but are not limited to, a change in the product mix, a change in the way products are created, produced or delivered, or a significant change in the way the Company's products are branded and marketed. When performing a review for recoverability, management estimates the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The amount of the impairment loss, if impairment exists, is calculated based on the excess of the carrying amounts of the assets over their estimated fair value computed using discounted cash flows.

Customer Deposits

The Company requires deposits in advance of shipment for certain customer sales orders. Customer deposits are recorded as a current liability in the accompanying consolidated balance sheets.

Revenue Recognition, Deferred Revenue and Accounts and Notes Receivable

The Company derives revenue from two primary sources: (1) the sale of physical products, including our CEWs, AXON cameras, corresponding extended warranties, and related accessories such as cartridges and batteries, and (2) subscription to the Company's EVIDENCE.com SaaS (including data storage fees and other ancillary services), which includes varying levels of support. To a lesser extent, the Company also recognizes training and other revenue. Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, title has transferred, the price is fixed and collectability is reasonably assured. Extended warranty revenue, SaaS revenue and related data storage revenue are recognized ratably over the term of the contract beginning on the commencement date of each contract.

Revenue arrangements with multiple deliverables are divided into separate units and revenue is allocated using the relative selling price method based upon vendor-specific objective evidence of selling price or third-party evidence of the selling prices if vendor-specific objective evidence of selling prices does not exist. If neither vendor-specific objective evidence nor third-party evidence exists, management uses its best estimate of selling price.

The Company offers the right to purchase extended warranties that include additional services and coverage beyond the limited warranty for certain products. Revenue for extended warranty purchases is deferred at the time of sale and recognized over the warranty period commencing on the date of sale. Extended warranties range from one to five years.

EVIDENCE.com and AXON cameras are sometimes sold separately, but in most instances are sold together. In these instances, customers typically purchase and pay for the equipment and one year of EVIDENCE.com in advance. Additional years of service are generally billed annually over a specified service term, which has typically ranged from one to five years. AXON equipment has stand-alone value and represents a deliverable that is provided to the customer at the time of sale, while EVIDENCE.com services are provided over the specified term of the contract. The Company recognizes revenue for the AXON equipment at the time of the sale consistent with the discussion of multiple deliverable arrangements above. Revenue for EVIDENCE.com is deferred at the time of the sale and recognized over the service period. In certain circumstances, not all requirements are met for the recognition of revenue relative to equipment sold in conjunction with EVIDENCE.com at the time the equipment is provided to customers. In such circumstances, based on limitations associated with the allocation of arrangement consideration, part of the revenue may be recognized ratably over the specified term of the contract, or when all conditions for revenue recognition are met, if sooner.

In 2012, the Company introduced a program, the TASER Assurance Program (“TAP”) whereby a customer purchasing a product and joining the program will have the right to trade-in the original product for a new product of the same or like model in the future. Upon joining TAP, customers also receive an extended warranty for the initial products purchased and spare inventory. Under this program the customer generally pays additional annual installments over the contract period, generally three to five years. The Company records consideration received related to the future product purchase as deferred revenue until all revenue recognition criteria are met, which is generally at the end of the contract period.

Sales tax collected on sales is netted against government remittances and thus, recorded on a net basis. Training revenue is recorded as the service is provided.

Deferred revenue consists of payments received in advance related to products and services for which the criteria for revenue recognition have not yet been met. Deferred revenue that will be recognized during the succeeding twelve month period is recorded as current deferred revenue and the remaining portion is recorded as long-term. Deferred revenue does not include future revenue from multi-year contracts for which no invoice has yet been created. Generally, customers are billed in annual installments. See Note 7 for further disclosures about of the Company’s deferred revenue.

Sales are typically made on credit and the Company generally does not require collateral. Management performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for estimated potential losses. Uncollectible accounts are charged to expense when deemed uncollectible, and accounts and notes receivable are presented net of an allowance for doubtful accounts. This allowance represents management’s best estimate and is based on their judgment after considering a number of factors, including third-party credit reports, actual payment history, cash discounts, customer-specific financial information and broader market and economic trends and conditions.

The Company may, from time to time, enter into agreements with its customers to finance their purchases with a note receivable that may range in terms up to five years. Sales are recorded at the fair value of the note, which is generally sold and assigned to a third-party financing company. The terms of the assignments are such that the Company expects to receive payment within 30 days of the original sale. The assignments are non-recourse and the Company has no obligations or continuing involvement with the notes receivable. Prior to entering into an assignment, the Company evaluates the credit quality and financial condition of the third-party financing company. The Company does not generally record interest income on notes receivable due to minimal holding periods, nor has the Company recognized gains or losses upon the assignment of the notes. As of December 31, 2014 and 2013, there was no balance in accounts and notes receivable related to such arrangements.

Cost of Products Sold and Services Provided

Cost of products sold represents manufacturing costs, consisting of materials, labor and overhead related to finished goods and components. Shipping costs incurred related to product delivery are also included in cost of products sold. Cost of services delivered includes third party cloud services, and software maintenance costs, including personnel costs, associated with supporting EVIDENCE.com.

Advertising Costs

The Company expenses advertising costs in the period in which they are incurred. The Company incurred advertising costs of $0.3 million, $0.2 million and $0.2 million in the years ended December 31, 2014, 2013 and 2012, respectively. Advertising costs are included in sales, general and administrative expenses in the accompanying statements of operations.

Standard Warranties

The Company warranties its CEWs, AXON cameras and E-Docks from manufacturing defects on a limited basis for a period of one year after purchase and, thereafter, will replace any defective unit for a fee. Estimated costs for the standard warranty are charged to cost of products sold and services delivered when revenue is recorded for the related product. Future warranty costs are estimated based on historical data related to returns and warranty costs on a quarterly basis and this rate is applied to current product sales. Historically, reserve amounts have been increased if management becomes aware of a component failure that could result in larger than anticipated returns from customers. The accrued warranty liability expense is reviewed quarterly to verify that it sufficiently reflects the remaining warranty obligations based on the anticipated expenditures over the balance of the warranty obligation period, and adjustments are made when actual warranty claim experience differs from estimates. Costs related to extended warranties are charged to cost of products sold and services delivered when incurred. The reserve for warranty returns is included in accrued liabilities on the accompanying consolidated balance sheets.

Research and Development Expenses

The Company expenses as incurred research and development costs that do not meet the qualifications to be capitalized.

Income Taxes

Income taxes are accounted for 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 amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in future years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced through the establishment of a valuation allowance if, based upon available evidence, it is determined that it is more likely than not that the deferred tax assets will not be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. Management also assesses whether uncertain tax positions, as filed, could result in the recognition of a liability for possible interest and penalties. The Company’s policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense. Refer to Note 10 for additional information regarding the change in unrecognized tax benefits.

Concentration of Credit Risk and Major Customers / Suppliers

Financial instruments that potentially subject the Company to concentrations of credit risk consist of accounts and notes receivable and cash. Sales are typically made on credit and the Company generally does not require collateral. Management performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for estimated losses. Uncollectible accounts are written off when deemed uncollectible, and accounts receivable are presented net of an allowance for doubtful accounts, which totaled $0.3 million and $0.2 million as of December 31, 2014 and 2013, respectively. Historically, the Company has experienced a low level of write-offs related to doubtful accounts.

The Company maintains the majority of its cash and cash equivalents accounts at three depository institutions. As of December 31, 2014, the aggregate balances in such accounts were $48.4 million. The Company’s cash balances with these institutions regularly exceed FDIC insured limits; however, to manage the related credit exposure, management continually monitors the creditworthiness of the financial institutions where the Company has deposits.

The Company sells its products primarily through a network of unaffiliated distributors. The Company also reserves the right to sell directly to the end user to secure the customer’s account. In 2014, no customer represented more than 10% of total net sales. In 2013 and 2012 one distributor represented 12.2% and 12.8%, respectively, of total net sales with no other customers exceeding 10%.

At December 31, 2014, the Company had a trade receivable from one unaffiliated customer comprising 13.4% of the aggregate accounts receivable balance. At December 31, 2013, the Company had a trade receivable from one unaffiliated customer comprising 17.4% of the aggregate accounts receivable balance.

The Company currently purchases finished circuit boards and injection-molded plastic components from suppliers located in the U.S. Although the Company currently obtains many of these components from single source suppliers, the Company owns the injection molded component tooling used in their production. As a result, management believes it could obtain alternative suppliers in most cases without incurring significant production delays. The Company also purchases small, machined parts from a vendor in Taiwan, custom cartridge assemblies from a proprietary vendor in the U.S., and electronic components from a variety of foreign and domestic distributors. Management believes that there are readily available alternative suppliers in most cases who can consistently meet the Company's needs for these components. The Company acquires most of its components on a purchase order basis and does not have long-term contracts with suppliers.

Fair Value of Financial Instruments

The Company uses the fair value framework that prioritizes the inputs to valuation techniques for measuring financial assets and liabilities measured on a recurring basis and for non-financial assets and liabilities when these items are re-measured. Fair value is considered to be the exchange price in an orderly transaction between market participants, to sell an asset or transfer a liability at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

•

Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

•

Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

•

Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Company's own assumptions about inputs that market participants would use in pricing an asset or liability.

The Company has cash equivalents and investments, which at December 31, 2014 and 2013, were comprised of money market funds, state and municipal obligations, corporate bonds, and certificates of deposits. See additional disclosure regarding the fair value of the Company’s cash equivalents and investments in Note 2. Included in the balance of other assets as of December 31, 2014 and 2013 was $1.1 million and $0.4 million, respectively, related to corporate-owned life insurance policies which are used to fund the Company’s deferred compensation plan. The Company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer, a Level 2 valuation technique.

The Company’s financial instruments also include accounts and notes receivable, accounts payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the balance sheet.

Segment and Geographic Information

The Company is comprised of two reportable segments: the sale of CEWs, accessories and other products and services (the “TASER Weapons” segment); and the video business which includes the TASER Cam, AXON camera products and EVIDENCE.com (the “AXON” segment). Reportable segments are determined based on discrete financial information reviewed by the Company’s Chief Executive Officer who is the Chief Operating Decision Maker (the “CODM”) for the Company. The Company organizes and reviews operations based on products and services, and currently there are no operating segments that are aggregated. The Company performs an annual analysis of its reportable segments. Additional information related to the Company’s business segments is summarized in Note 15.

For the three years ended December 31, 2014, 2013 and 2012, net sales by geographic area were as follows (in thousands):

Sales to customers outside of the U.S. are typically denominated in U.S. dollars and are attributed to each country based on the shipping address of the distributor or customer. For the three years ended December 31, 2014, 2013 and 2012, no individual country outside the U.S. represented more than 10% of net sales. Substantially all of the Company’s assets are located in the U.S.

Stock-Based Compensation

The Company calculates the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock units is estimated as the closing price of our common stock on the date of grant. No options were awarded during the years ended December 31, 2014, 2013 or 2012.

The expected life of the options represents the estimated period of time from grant date until exercise and is based on historical experience of similar awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. Expected stock price volatility is based on a combination of historical volatility of the Company’s stock and the one-year implied volatility of its publicly traded options for the related vesting periods. The risk-free interest rate is based on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term. The Company has not paid dividends in the past and does not plan to pay any dividends in the near future.

The estimated fair value of stock-based compensation awards is amortized to expense on a straight-line basis over the requisite service periods. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company’s forfeiture rate was calculated based on its historical experience of awards which ultimately vested. See Note 12 for further disclosure about of the Company’s stock-based compensation.

Income per Common Share

Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted income per share reflects the potential dilution that would occur if outstanding stock options were exercised utilizing the treasury stock method.

Recently Issued Accounting Guidance

In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation—Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (i) prospectively to all awards granted or modified after the effective date; or (ii) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company is currently evaluating the potential impact of the adoption of this guidance on its consolidated financial statements, however does not expect there to be a material impact at this time.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, ASU 2014-09 provides for the following steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification Topic No. 605, “Revenue Recognition,” most industry-specific guidance throughout the industry topics of the Accounting Standards Codification, and some cost guidance related to construction-type and production-type contracts. ASU 2014-09 is effective for public entities for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company is currently evaluating the potential impact of the adoption of this guidance on its consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11 to standardize the balance sheet presentation of unrecognized tax benefits. This update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The new guidance was effective for fiscal years beginning after December 15, 2013. The adoption of this guidance resulted in an immaterial reclassification on the Company’s consolidated balance sheet.

Foreign Currency Translation

The Company’s foreign subsidiary uses the local currency as its functional currency. Assets and liabilities are translated at exchange rates in effect at the balance sheet date. Income and expense accounts are translated at the average monthly exchange rates during the year. Resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss) on the consolidated balance sheets.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations.
