SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Accounting Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates these estimates, including those related to allowance for doubtful accounts, inventory valuation, vendor deposits, warranty costs, stock-based compensation and income taxes, among others. The Company bases estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ materially from these estimates.

Segments

Management has determined that it operates as one reportable and operating segment as the Company's Chief Executive Officer, who is the Company's chief operating decision maker, does not make decisions about resources to be allocated or assess performance on a segment basis. See Note 12.

Recognition of Revenues

Revenues consist primarily of revenues from the sale of hardware and management tools, as well as the related implied post contract customer support (“PCS”). The Company recognizes revenues when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and the collectability of the resulting receivable is reasonably assured. In cases where the Company lacks evidence that collectability of the resulting receivable is reasonably assured, it defers recognition of revenue until the receipt of cash.

For the Company’s sales, evidence of the arrangement consists of an order from a customer. The Company considers delivery to have occurred once its products have been shipped and title and risk of loss have been transferred. For the Company’s sales, these criteria are met at the time the products are transferred to the customer. The Company’s arrangements with customers do not, in most cases, include provisions for cancellation, returns, inventory swaps or refunds that would materially impact recognized revenues.

The Company records amounts billed to distributors for shipping and handling costs as revenues. The Company classifies shipping and handling costs incurred by it as cost of revenues.

Deposit payments received from distributors in advance of recognition of revenues are included in current liabilities on the Company’s balance sheet and are recognized as revenues when all the criteria for recognition of revenues are met.

A portion of the Company's revenues related to PCS are deferred. This relates to the Company’s multi-element arrangements, which generally include two deliverables. The first deliverable is the hardware and software essential to the functionality of the hardware device delivered at the time of sale. The second deliverable is the implied right to PCS included with the purchase of certain products. PCS is this right to receive, on a when and if available basis, future unspecified software upgrades and features relating to the product’s essential software as well as bug fixes, email and telephone support.

The Company uses a hierarchy to determine the allocation of revenues to the deliverables. The hierarchy is as follows: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of the selling price (“BESP”).


(i)	VSOE generally exists only when a company sells the deliverable separately and is the price actually charged by the company for that deliverable. Generally, the Company does not sell the deliverables separately and, as such, does not have VSOE.


(ii)	TPE can be substantiated by determining the price that other parties sell similar or substantially similar offerings. The Company does not believe that there is accessible TPE evidence for similar deliverables.


(iii)	BESP reflects the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. The Company believes that BESP is the most appropriate methodology for determining the allocation of revenue among the multiple elements.

The Company allocates revenues between these two deliverables using the relative selling price method which is based on the estimated selling price for all deliverables. Revenues allocated to the delivered hardware and the related essential software are recognized at the time of sale provided the other conditions for recognition of revenues have been met. Revenues allocated to the PCS are deferred and recognized on a straight-line basis over the estimated period for which services will be delivered to support each of these devices which, currently, is two years. If the estimated life of the hardware product should change, the future rate of amortization of the revenues allocated to PCS would also change. All cost of revenues for the delivered hardware and the related essential software, including estimated warranty costs, are recognized at the time of sale. Costs for research and development and sales and marketing are expensed as incurred. Costs for PCS are recognized as they are incurred.

The Company’s process for determining BESP for deliverables involves multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. For PCS, the Company believes its network operators and service providers would be reluctant to pay for such services separately. This view is primarily based on the fact that unspecified upgrade rights do not obligate the Company to provide upgrades at a particular time or at all, and do not specify to network operators and service providers which upgrades or features will be delivered. The Company believes that the relatively low prices of its products and its network operators’ and service providers’ price sensitivity would add to their reluctance to pay for PCS. Therefore, the Company has concluded that if it were to sell PCS on a standalone basis, the selling price would be relatively low.

Key factors considered by the Company in developing the BESP for PCS include reviewing the activities of specific employees engaged in support and software development to determine the amount of time that is allocated to the development of the undelivered elements, determining the cost of this development effort, and then adding an appropriate level of gross profit to these costs. As of June 30, 2017 and 2016, the Company had deferred revenues of $7.9 million and $4.2 million, respectively, related to these obligations.

Cash and Cash Equivalents

The Company considers investments purchased with a maturity period of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost which approximates fair value. The Company deposits cash and cash equivalents with financial institutions that management believes are of high credit quality. The Company’s cash and cash equivalents consist primarily of cash deposited in U.S. dollar denominated interest-bearing deposit accounts.

Concentration of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company limits its exposure by primarily placing its cash in interest-bearing deposit accounts with high credit quality financial institutions.

The Company derives its accounts receivable from revenues earned from customers located worldwide. The Company bases credit decisions primarily upon a customer’s past credit history. The Company’s standard credit terms are net 30 to 120 days.

The Company subcontracts with other companies to manufacture most of its products. The Company relies on the ability of these contract manufacturers to produce the products sold to its distributors. A significant portion of the Company’s products are manufactured by a few contract manufacturers.

Inventory and Inventory Valuation

The Company's inventories are primarily finished goods and, to a lesser extent, raw materials, which have been either consigned to the Company's contract manufacturers or are held by the Company. Inventories are stated at the lower of actual cost (computed on a first-in, first-out basis), or Net Realizable Value (NRV). NRV is based upon an estimated average selling price reduced by the estimated costs of disposal. The determination of net realizable value involves numerous judgments including estimating average selling prices based up recent sales, industry trends, existing customer orders, and seasonal factors. Should actual market conditions differ from the Company's estimates, future results of operations could be materially affected. The Company reduces the value of its inventory for estimated obsolescence or lack of marketability by the difference between the cost of the affected inventory and the estimated market value. Write-downs are not reversed until the related inventory has been subsequently sold or scrapped.

The valuation of inventory also requires the Company to estimate excess and obsolete inventory. The determination of excess or obsolete inventory is estimated based on a comparison of the quantity and cost of inventory on hand to the Company's forecast of customer demand. Customer demand is dependent on many factors and requires the Company to use significant judgment in our forecasting process. The Company also makes assumptions regarding the rate at which new products will be accepted in the marketplace and at which customers will transition from older products to newer products. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required, which would have a negative impact on the Company's gross margin. If the Company ultimately sells inventory that has been previously written down, the Company's gross margins in future periods would be positively impacted.

In fiscal 2016, the Company began capitalizing manufacturing overhead expenditures as part of inventory costs. Capitalized

costs primarily include management’s best estimate of the direct labor and materials costs related to inventory produced but not

sold during the period. Manufacturing overhead costs are capitalized to inventory and are recognized as cost of revenues in the following quarter, consistent with the Company's historical inventory turnover.

Product Warranties

The Company offers warranties on certain products, generally for a period of one year, and records a liability for the estimated future costs associated with potential warranty claims. The warranty costs are reflected in the Company’s consolidated statement of operations and comprehensive income within cost of revenues. The warranties are typically in effect for 12 months from the distributor’s purchase date of the product. The Company’s estimate of future warranty costs is largely based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. In certain circumstances, the Company may have recourse from its contract manufacturers for replacement cost of defective products, which it also factors into its warranty liability assessment.

Allowance for Doubtful Accounts

The Company records an allowance for doubtful accounts for estimated probable losses on uncollectible accounts receivable. In estimating the allowance, management considers, among other factors, (i) the aging of the accounts receivable, (ii) the Company’s historical write offs, (iii) the credit worthiness of each distributor based on payment history and (iv) general economic conditions. In cases where the Company is aware of circumstances that may impair a specific distributor’s ability to meet its obligations to the Company, the Company records a specific allowance against amounts due from the distributor, and thereby reduces the net recognized receivable to the amounts it reasonably believes will be collected.

The allowance for doubtful accounts activity was as follows (in thousands):



	Years Ended June 30,
	2017		2016			2015
Beginning balance	$	48	$	1,071		$	1,395
Charged to (released from) expenses	392		(1		)	106
Bad debt write-offs	—		(1,022		)	(430		)
Ending balance	$	440	$	48		$	1,071

Fair Value of Financial Instruments

Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The accounting guidance establishes a three-tier fair value hierarchy that requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The fair value hierarchy prioritizes the inputs into three levels that may be used in measuring fair value as follows:

Level 1—observable inputs which include quoted prices in active markets for identical assets of liabilities.

Level 2—inputs which include observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3—inputs which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation.

Long Lived Assets

The Company evaluates its long lived assets including property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or asset group. If impairment is indicated, the asset is written down to its estimated fair value. In fiscal 2016, the Company recorded a $2.5 million impairment charge for capitalized software development costs due to the cancellation of the commercial launch of certain software in development. The Company did not recognize any significant impairment loss for fiscal 2017 or 2015.

Property and Equipment

Furniture, fixtures and equipment are recorded at cost. The Company also capitalizes certain costs of software developed for internal use, which is included as property and equipment on the Company's consolidated balance sheets. Capitalized costs primarily include payroll and payroll-related costs and facilities costs.

The Company computes depreciation or amortization using the straight line method over estimated useful lives, as follows:



		Estimated Useful Life
Testing equipment		3 to 5 years
Computer and other equipment		3 to 5 years
Furniture and fixtures		3 to 5 years
Software		up to 3 years
Leasehold improvements		shorter of lease term or useful life

Upon retirement or disposition, the asset cost and related accumulated depreciation are removed with any gain or loss recognized in the statement of operations. Expenditures for maintenance and repairs are charged to operations as incurred.

Intangible Assets

The Company’s intangible assets consist primarily of legal costs associated with application for and registration of the Company’s trademarks. The Company amortizes all definite-lived intangible assets that are subject to amortization over the estimated useful life based on economic benefit, which is generally 5 years. All patent filing and defense costs are expensed as incurred, however to date these costs have not been significant.

Leases

The Company leases its facilities under cancelable and noncancelable operating leases. For leases that contain rent escalation or rent concessions provisions, the Company records the total rent expense during the lease term on a straight line basis over the term of the lease. The Company records the difference between the rent paid and the straight line rent as a deferred rent liability on the consolidated balance sheets.

Advertising Costs

The Company expenses all advertising costs as incurred.

Income Taxes

The Company accounts for income taxes in accordance with accounting guidance which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in its financial statements or tax returns. Deferred tax assets and liabilities are determined based on the temporary difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company establishes valuation allowances when necessary to reduce deferred tax assets to the amount it expects to realize. The assessment of whether or not a valuation allowance is required often requires significant judgment including current operating results, the forecast of future taxable income and ongoing prudent and feasible tax planning initiatives. In addition, the Company’s calculation of its tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company may be subject to income tax audits in all of the jurisdictions in which it operates and, as a result, must also assess exposures to any potential issues arising from current or future audits of current and prior years’ tax returns. Accordingly, the Company must assess such potential exposures and, where necessary, provide a reserve to cover any expected loss. To the extent that the Company establishes a reserve, its provision for income taxes would be increased. If the Company ultimately determines that payment of these amounts is unnecessary, it reverses the liability and recognizes a tax benefit during the period in which it determines that the liability is no longer necessary. The Company records an additional charge in its provision for taxes in the period in which it determines that tax liability is greater than its original estimate. The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.

Stock-based Compensation

The Company records stock-based awards at fair value as of the grant date and recognize expense, net of forfeitures, ratably on a straight-line basis over the requisite service period, which is generally the vesting term of the awards. The Company did not grant any stock options during fiscal 2017, fiscal 2016, or fiscal 2015. Restricted stock units are valued based on the fair value of the Company's common stock on the date of grant. Since the Company's initial public offering on October 14, 2011, the fair value of our common stock is determined using the closing market price of the Company's common stock as of the date of grant.

Commitments and Contingencies

The Company periodically evaluates all pending or threatened contingencies and any commitments, if any, that are reasonably likely to have a material adverse effect on its results of operations, financial position or cash flows. The Company assesses the probability of an adverse outcome and determines if it is remote, reasonably possible or probable. If information available prior to the issuance of the Company’s financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the Company’s financial statements, and the amount of the loss, or the range of probable loss can be reasonably estimated, then such loss is accrued and charged to operating expenses. If no accrual is made for a loss contingency because one or both of the conditions pursuant to the accounting guidance are not met, but the probability of an adverse outcome is at least reasonably possible, the Company discloses the nature of the contingency and provides an estimate of the possible loss or range of loss, or states that such an estimate cannot be made.

Foreign Currency Remeasurement

The functional currency of the Company and its subsidiaries is the U.S. dollar. For foreign operations, local currency denominated monetary assets and liabilities are remeasured at the period end exchange rates, and revenues, costs and expenses are remeasured at the average exchange rates during the fiscal year. Foreign exchange gains and losses have been immaterial to the Company’s results of operations to date.

Research and Development Costs

Research and development expenses are expensed as incurred and consist primarily of payroll and payroll-related costs and facilities costs. Research and development expenses associated with software development are typically expensed as incurred as our software is usually released to end customers immediately after technological feasibility has been established. However, the Company capitalizes development costs when material costs are incurred subsequent to technological feasibility but prior to commercial release.

Earnings Per Share

The Company applies the treasury stock method for calculating and presenting earnings per share (“EPS”). Basic EPS is computed by dividing the net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS available to common stockholders is computed by dividing the amount of net income available to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options and restricted stock units using the treasury stock method.

Recent Accounting Pronouncements

Effective July 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-03, regarding simplifying the presentation of debt issuance costs. The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Previously the Company reported these costs as assets on its balance sheet. The guidance is applied on a retrospective basis whereby prior-period financial statements must be adjusted to reflect the adoption of the new guidance. The guidance only resulted in a reclassification on the Company's consolidated balance sheet. The Company has reclassified $0.3 million from "prepaid expenses and other current assets" to "Debt - short-term", and $0.7 million from "Other long-term assets"

to "Debt - long-term" on the June 30, 2016 consolidated balance sheet.

Effective July 1, 2016, the Company adopted ASU 2015-11, "Inventory (Topic 330)-Simplifying the Measurement of Inventory, ("ASU 2015-11"). The guidance requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this update prospectively, and it did not have a material impact on the Company's consolidated financial statements.

Effective July 1, 2016, the Company early adopted ASU 2016-09,"Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting," ("ASU 2016-09"), regarding the Improvements to Employee Share-Based Payment Accounting. The Company applied the guidance relating to accounting for excess tax benefits and the presentation of excess tax benefits in the consolidated statement of cash flows on a prospective basis; accordingly, prior period amounts have not been adjusted. During fiscal 2017, the Company recognized the excess tax benefits of $7.9 million, within the provision for income taxes rather than additional paid-in capital. The Company classified the excess tax benefits within cash flows from operating activities for year ended June 30, 2017, rather than within cash flows from financing activities. In regard to the forfeiture policy election, we will continue to estimate the number of awards expected to be forfeited, rather than electing to account for forfeitures as they occur. No other terms of the adopted guidance resulted in an impact on the Company's consolidated financial statements.

In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other Than Inventory," (“ASU 2016-16”). ASU 2016-16 eliminates the exception for all intra-entity sales of assets other than inventory. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017, and early adoption is permitted but can only be adopted in the first interim period of a fiscal year. The Company is evaluating the impact that adoption of this new standard will have on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (TOPIC 326): Measurement of Credit Losses On Financial Instruments” ("ASU 2016-13"). ASU 2016-13 implements a comprehensive change in estimating the allowances for loan losses from the current model of losses inherent in the loan portfolio to a current expected credit loss model that generally is expected to result in earlier recognition of allowances for losses. Additionally, purchase accounting rules have been modified as well as credit losses on held-to-maturity debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is evaluating the impact that adoption of this new standard will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for leases with lease terms greater than twelve months and disclose key information about leasing arrangements. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years, with early application permitted. The Company is evaluating the impact that adoption of this new standard will have on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , with amendments in 2015 and 2016, which creates new ASC Topic 606 (Topic 606) that will replace most existing revenue recognition guidance in GAAP when it becomes effective. Topic 606 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The new standard will be effective for the Company’s first quarter of fiscal year 2019 and early application for the Company's first quarter of fiscal year 2018 is permitted. Topic 606 may be applied retrospectively to each prior period presented or with the cumulative effect recognized as of the date of initial application. The Company is still evaluating the impact of adopting Topic 606 on its consolidated financial statements and related financial statement disclosures and has determined that it will not early adopt this standard in fiscal 2018, however it has not yet selected a transition method for its adoption of this standard in fiscal 2019.
