| Organization and Summary of Significant Accounting Policies | Organization and Summary of Significant Accounting Policies Axon Enterprise, Inc. (“Axon” or the “Company”) is a developer and manufacturer of advanced conducted electrical weapons (“CEWs”) designed for use by law enforcement, military, corrections, private security personnel, and by private individuals for personal defense. In addition, the Company has developed full technology solutions for the capture, secure 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 division is located in Seattle, Washington. Axon Public Safety BV, a wholly owned subsidiary of the Company, supports the Company's international sales and marketing efforts, and is located in Amsterdam, Netherlands. Axon Public Safety BV wholly owns two subsidiaries, Axon Public Safety U.K. LTD and Axon Public Safety AU, that serve as direct sales operations in the United Kingdom ("U.K.") and Australia, respectively. The Company also sells to certain international markets through a wholly owned subsidiary, Axon Public Safety Germany SE. In 2015, the Company formed Axon Public Safety Canada, Inc., a wholly owned subsidiary, to facilitate transactions for its products and services with new and existing customers located in Canada. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany accounts, transactions, and profits have been eliminated. a. Basis of Presentation and Use of Estimates These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information related to the Company’s organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“US GAAP”) has been condensed or omitted. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in the Company’s annual consolidated financial statements for the year ended December 31, 2016 , as filed on Form 10-K. In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to fairly state the Company’s financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with the Company’s Form 10-K for the year ended December 31, 2016 . The results of operations for the nine months ended September 30, 2017 and 2016 are not necessarily indicative of the results to be expected for the full year (or any other period). Significant estimates and assumptions in these unaudited condensed consolidated financial statements include: • product warranty reserves, • inventory valuation, • 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 and the estimated vesting period for performance-based stock awards, and • recognition and measurement of contingencies and accrued litigation expense. Actual results could differ materially from those estimates. b. Segment Information The Company is comprised of two reportable segments: the manufacture and sale of CEWs, accessories and other products and services (the “TASER Weapons” segment); and the software and sensors business, which includes the TASER Cam, Axon cameras and related accessories, Evidence.com, and the Axon Artificial Intelligence team ("Axon AI") (collectively, the “Software and Sensors” 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 14. c. Geographic Information and Major Customers For the three and nine months ended September 30, 2017 and 2016 , net sales by geographic area were as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 United States $ 73,203 81.1 % $ 60,558 84.2 % $ 204,155 81.9 % $ 155,245 83.4 % Other Countries 17,059 18.9 11,324 15.8 44,992 18.1 30,923 16.6 Total $ 90,262 100.0 % $ 71,882 100.0 % $ 249,147 100.0 % $ 186,168 100.0 % 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 months ended September 30, 2017, one country, the U.K. represented more than 10% of the Company's net sales at 10.5% . For the nine months ended September 30, 2017 and the three and nine months ended September 30, 2016 , no individual country outside the U.S. represented more than 10% of net sales. Individual sales transactions in the international market are generally larger and occur more intermittently than in the domestic market due to the profile of the Company's customers. For the three and nine months ended September 30, 2017 and 2016 , no customer represented more than 10% of total net sales. At September 30, 2017 , the Company had a trade receivable from one customer comprising 10.3% of the aggregate accounts receivable balance. At December 31, 2016 , the Company had a trade receivable from one customer comprising 14.5% of the aggregate accounts receivable balance. d. 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. Potentially dilutive securities include outstanding stock options and unvested restricted stock units. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. The calculation of the weighted average number of shares outstanding and earnings per share are as follows (in thousands except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Numerator for basic and diluted earnings per share: Net income $ 422 $ 3,843 $ 7,278 $ 10,956 Denominator: Weighted average shares outstanding - basic 52,831 52,206 52,663 52,791 Dilutive effect of stock-based awards 1,012 935 1,099 865 Diluted weighted average shares outstanding 53,843 53,141 53,762 53,656 Anti-dilutive stock-based awards excluded 575 227 506 304 Net income per common share: Basic $ 0.01 $ 0.07 $ 0.14 $ 0.21 Diluted $ 0.01 $ 0.07 $ 0.14 $ 0.20 e. Revenue Recognition, Deferred Revenue and Accounts and Notes Receivable The Company derives revenue from two primary sources: (1) the sale of physical products, including CEWs, Axon cameras, corresponding hardware extended warranties, and related accessories such as Axon docks, cartridges and batteries, among others, and (2) subscription to the Company's Evidence.com digital evidence management software as a service ("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 professional services 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. Contractual arrangements may contain explicit customer acceptance provisions, and under such arrangements, the Company defers recognition of revenue until formal customer acceptance is received. Extended warranty revenue, SaaS revenue and related data storage revenue are recognized ratably over the term of the contract commencing on a pre-determined date subsequent to the delivery of the hardware. Training and professional service revenues are generally recorded once the services are completed. 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 ("VSOE") 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 majority of the Company’s allocations of arrangement consideration under multiple element arrangements are performed utilizing prices charged to customers for deliverables when sold separately. The Company’s multiple element arrangements may include future CEWs and/or Axon devices to be delivered at defined points within a multi-year contract, and in those arrangements, the Company allocates total arrangement consideration over the life of the multi-year contract to future deliverables using management’s best estimate of selling price. The Company has not utilized third party evidence of selling price. The Company offers the right to purchase extended warranties that include additional services and coverage beyond the standard 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 and related accessories have stand-alone value to the customer and are sometimes sold separately, but in most instances are sold together. In most instances, customers generally 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. Generally, 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. At times the Company discounts the cost of Axon devices provided to customers to secure long-term Evidence.com service contracts. In such circumstances, revenue related to the Axon devices recognized at the time of delivery is limited to the amount allocated to the Axon device deliverable that the Company is contractually entitled to that is not contingent upon the delivery of future Evidence.com services. The Company recognizes the remaining allocated revenue related to discounted Axon devices over the remaining period it provides the contracted Evidence.com services. 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 when the new product is delivered. Consideration related to future product purchases is determined at the inception of the arrangement using management’s best estimate of selling price. Management’s estimate is principally based on the current selling price for such products, with due evaluation of the impact of any expected product and pricing changes, which have historically had an immaterial influence on management’s best estimate of selling price. In 2015, The Company introduced the Officer Safety Plan (“OSP”) whereby a customer enters into a five -year Evidence.com subscription that includes all of its standard advanced features along with unlimited storage. The OSP also includes a service plan that includes upgrades of (i) the Axon devices every 2.5 years and (ii) a TASER CEW at any point within the contract period. Upon entering into the OSP, customers also receive extended warranties on the Axon and CEW devices upon delivery to cover the contract periods as well as spare inventory units. Under this program the customer generally makes an initial purchase of Axon cameras and related accessories, and CEWs at inception along with annual installments for services and future hardware deliverables over the contract period. The Company records consideration received related to the future deliverables as deferred revenue until all revenue recognition criteria are met, which is generally when the products or services are delivered. In 2016, the Company introduced the TASER 60 Plan ("TASER 60") whereby a customer typically enters into a five year CEW installment purchase arrangement. TASER 60 also includes extended warranties on the CEW devices upon delivery covering the contract periods as well as on-site spares, holsters and cartridges. Generally, the Company allocates revenue to the deliverables using the relative selling price method and recognizes revenue for the amount allocated to the CEW devices at the time of sale for the amount allocated to the CEW devices, net of imputed interest, and the amount allocated to the extended warranty is recognized over five years. The Company performs an initial credit evaluation prior to execution of TASER 60 arrangements and subsequently performs quarterly credit evaluations by monitoring public municipal bond ratings, as applicable, and any subsequent credit upgrades or downgrades, to monitor for each customer's credit risk. Additionally, the Company tracks payment activity for amounts currently due to assess the credit quality of its notes receivable portfolio. As the Company’s customers generally have investment-grade municipal bond ratings, the Company considers collectability of the contracted amounts in such installment purchase arrangements to be reasonably assured, unless other factors or payment history indicate otherwise. For customers where municipal bond information is not available, the Company considers factors such as payment history, customer-specific information and broader market and economic trends and conditions to determine whether collectability is reasonably assured. The Company considers this information when establishing its allowance for doubtful accounts. For the three and nine months ended September 30, 2017 , the Company recorded revenue of $7.5 million and $20.8 million , respectively under the Company’s TASER 60 plan, and recorded $5.0 million and $8.6 million , respectively, for the same periods in 2016. In 2017, the Company introduced new subscription programs that allow for agencies to purchase the Company's training and duty cartridges over a five -year term whereby the customer would make five equal annual installments. The Company offers two tiers under this program: the basic and unlimited plan. The Axon Basic Cartridge Plan entitles customers to a fixed number of training and duty cartridges per year as well as a fixed number of battery replacements over the contractual term. For the Basic Cartridge Plan, the Company allocates the contractual consideration to all identified deliverables using the relative selling price method. Generally, the Company recognizes revenue for the amounts allocated to the cartridges when they are delivered to the customer. The Unlimited Cartridge Plan entitles customers to a fixed number of training cartridges per year and an unlimited amount of duty cartridges and replacement batteries. Due to the unlimited nature of the arrangement whereby the Company is obligated to deliver unlimited products at the customer’s request, the Company accounts for these arrangements as stand-ready obligations, and recognizes revenue ratably over the contract period. Cost of product sales is recognized as the products are delivered to the customer. Sales tax collected on sales is netted against government remittances and thus, recorded on a net basis. 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 6 for further disclosures about the Company’s deferred revenue. The Company records reductions to net sales for expected future product returns based on the Company’s historical experience. 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 use of estimates, and is based on 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. f. Standard Warranties The Company warranties its CEWs, Axon cameras and certain related accessories 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 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 or other issue that could result in larger than anticipated returns from customers. The accrued warranty liability 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. The reserve for warranty returns is included in accrued liabilities on the accompanying condensed consolidated balance sheets. Changes in the Company’s estimated product warranty liabilities were as follows (in thousands): Nine Months Ended September 30, 2017 2016 Balance, beginning of period $ 780 $ 314 Utilization of accrual (178 ) (97 ) Warranty expense 117 531 Balance, end of period $ 719 $ 748 g. 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 September 30, 2017 and December 31, 2016 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 September 30, 2017 and December 31, 2016 was $3.7 million and $3.2 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, notes payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the accompanying condensed consolidated balance sheets. h. Valuation of Goodwill, Intangibles and Long-lived Assets Management evaluates whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and identifiable intangible assets, excluding goodwill and intangible assets with indefinite useful lives, may warrant revision or that the remaining balance of these assets may not be recoverable. Such circumstances 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 products are branded and marketed. In performing the 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. The Company does not amortize goodwill and intangible assets with indefinite useful lives, rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. The Company performs its goodwill and intangible asset impairment tests in the fourth quarter of each year. i. Recently Issued Accounting Guidance In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations and recognition of revenue as the entity satisfies the performance obligations. Subsequently, the FASB issued the following accounting standard updates related to Topic 606, Revenue from Contracts with Customers: • ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) in March 2016. ASU 2016-08 does not change the core principle of revenue recognition in Topic 606 but clarifies the implementation guidance on principal versus agent considerations. • ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing in April 2016. ASU 2016-10 does not change the core principle of revenue recognition in Topic 606 but clarifies the implementation guidance on identifying performance obligations and its licensing. • ASUs 2016-12 and 2016-20, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, respectively, issued in May and December 2016, respectively. These ASUs do not change the core principle of revenue recognition in Topic 606 but clarify the implementation guidance on a few narrow areas and add some practical expedients to the guidance. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company's internal implementation team has completed the initial evaluation of the new standard, and is now working on the implementation of new technology systems and internal controls necessary to adopt the new guidance effective January 1, 2018. The Company intends to elect the modified retrospective method of adoption for all contracts that are not completed as of the adoption date. While the Company's assessment is not finalized, it believes the areas most significantly impacted will be contracts with contingent hardware revenue, the timing of recognition of contracts containing software licenses and post-contract customer support, and the treatment of incremental costs of obtaining contracts with customers. However, due to the complexity of certain customer contracts, the actual revenue recognition treatment required under the new standard will be dependent on contract-specific terms, and may vary in some instances from the recognition discussed below. • Currently, for bundled arrangements containing Evidence.com services where the Company has provided significantly discounted or free of charge hardware, the Company recognizes the revenue allocated to the hardware in excess of the invoiced amount over the contractual term when it is contingent on delivery of Evidence.com. Under ASU 2014-09, the Company anticipates being required to generally recognize hardware revenue upon fulfillment of the distinct hardware performance obligation when control transfers to the customer. • Currently, for sales of the Company's Axon Commander software product containing post-contract customer support ("PCS"), because the Company does not have sufficient VSOE to allocate the fee to the separate elements, the entire arrangement fee is recognized ratably over the support period term. Under the new standard, the Company expects to recognize the full amount of revenue attributable to the distinct software license predominately at the time the software is delivered to the customer, while the amount allocated to the PCS performance obligation will be recognized ratably over the support term. • Currently, the Company has an established policy to capitalize direct incremental costs of obtaining long-term customer contracts within the Software and Sensors segment as assets and recognize them as expense over the contractual term as the goods and services are delivered to the customer. The new guidance specifies that all incremental costs of obtaining customer contracts and direct costs of fulfilling our contracts with customers should be deferred and recognized when the related performance obligations are fulfilled over the contract term or expected customer life. The Company will modify its policy to defer all direct and incremental costs related to all customer contracts within both the Software and Sensors and TASER Weapons segments. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330). The amendments require that an entity should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this guidance effective January 1, 2017 and it did not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for the fiscal year beginning after December 15, 2018 (including interim periods within that year) using a modified retrospective approach and early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption of this ASU on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification (Topic 718), Compensation – Stock Compensation. ASU 2016-09 impacts several aspects of the accounting for share-based payment transactions. The Company adopted this guidance effective January 1, 2017, which required the following changes to the presentation of the Company's financial statements: • Excess tax benefits or deficiencies for share-based payments are now recorded as a discrete item in the period shares vest or stock options are exercised as an adjustment to income tax expense or benefit rather than additional paid-in capital. This change was applied prospectively as of January 1, 2017. The Company did not have any excess tax benefits that were not previously recognized as of January 1, 2017. • As of January 1, 2017, the calculation of diluted weighted average shares outstanding was changed prospectively to no longer include excess tax benefits as assumed proceeds. This change resulted in recording an increased number of dilutive shares, but did not have a material impact on the Company's current year diluted earnings per share; • Cash flows related to excess tax benefits or deficiencies are included in the statement of cash flows as an operating activity rather than as a financing activity. The Company adopted this change prospectively. • Cash paid to taxing authorities when withholding shares from an employee's vesting or exercise of equity-based compensation awards for tax-withholding purposes is now considered a repurchase of the Company's equity instruments and is classified as cash used in financing activities. The Company already classifies these transactions as a financing activity, and as such, there was no impact upon adoption. • The Company has made the election to account for forfeitures when they occur rather than estimating forfeitures. The Company adopted this change on a modified retrospective basis, which resulted in an increase to additional paid-in capital and decrease to retained earnings of $0.5 million as of December 31, 2016. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, which amends ASC 326. The new guidance differs from existing GAAP wherein prev |
