Accounting Policies [Abstract]

Overview and Basis of Presentation

Note 1: Overview and Basis of Presentation

Ooma, Inc. and its wholly-owned subsidiaries (collectively, “Ooma” or the “Company”) create new communications experiences for businesses and consumers, delivered from its smart cloud-based SaaS platforms.

Principles of Presentation and Consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation.

Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2020, fiscal 2019 and fiscal 2018 refer to the fiscal years ended January 31, 2020, January 31, 2019 and January 31, 2018, respectively.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the consolidated statements of operations and differences were not material. Therefore, the consolidated statements of comprehensive loss have been omitted.

Segment Reporting. The chief operating decision maker for the Company is the chief executive officer. The Company’s subscription plans, services and product offerings operate on SaaS platforms and the chief executive officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates in one reportable segment.

Revenue was principally derived from customers located in the United States for all periods presented. All of the Company’s long-lived assets were attributable to operations in the United States, with a small portion attributable to operations in Canada and other countries, for all periods presented.

Note 2: Significant Accounting Policies

Revenue Recognition

On February 1, 2018, the Company adopted Topic 606, Revenue from Contracts with Customers. The Company’s financial results for fiscal years 2020 and 2019 are presented in accordance with the provisions under Topic 606. Comparative prior period amounts for fiscal 2018 have not been adjusted and continue to be reported under Topic 605, Revenue Recognition, which is materially similar to Topic 606.

The Company derives its revenue from two sources: (1) subscription and services revenue, which is derived primarily from the sale of subscription plans for communications services and other connected services; and (2) product and other revenue. Subscriptions and services are sold directly to end-customers. Products are sold to end-customers through several channels, including but not limited to, distributors, retailers and resellers (collectively the “channel partners”), and Ooma sales representatives.

Under Topic 606, the Company determines revenue recognition through the following steps:

•

identification of the contract(s) with a customer;

•

identification of the performance obligations in the contract;

•

determination of the transaction price;

•

allocation of the transaction price to the performance obligations in the contract; and

•

recognition of revenue when, or as, the Company satisfies a performance obligation

Revenue is recorded net of any sales and telecommunications taxes collected from customers to be remitted to government authorities.

Revenue disaggregated by revenue source consisted of the following (in thousands):

	Fiscal Year Ended January 31,
	2020		2019		2018
Subscription and services revenue	$	139,499	$	116,429	$	101,999
Product and other revenue		12,094		12,802		12,491
Total revenue	$	151,593	$	129,231	$	114,490

The Company derived approximately 58%, 68% and 71% of its total revenue from Ooma Residential and approximately 39%, 28% and 22% from Ooma Business in fiscal 2020, 2019 and 2018, respectively. No individual country outside of the United States represented 10% or more of total revenue for the periods presented. No single customer accounted for 10% or more of total revenue for the periods presented.

Subscription and Services Revenue. Most of the Company’s revenue is derived from recurring subscription fees related to service plans such as Ooma Business, Ooma Residential and other communications services. Subscription revenue is generally recognized ratably over the contractual service term. The Company’s service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. A small portion of the Company’s revenue is recognized on an over-time basis from installation-related services and on a point-in-time basis from services such as: prepaid international calls, directory assistance, and advertisements displayed through its Talkatone mobile application.

Product and Other Revenue. Product and other revenue is generated from the sale of on-premise appliances and end-point devices, including shipping and handling fees for direct customers, and to a lesser extent from porting fees that enable customers to transfer their existing phone numbers. The Company recognizes revenue from sales to direct end-customers and channel partners at the point-in-time that control transfers, which is typically when it delivers the product or when all customer contractual provisions have been met, if any. The Company’s distribution agreements with channel partners typically contain clauses for price protection and right of return. Therefore, the amount of product revenue recognized is adjusted for any variable consideration, such as expected returns and customer sales incentives as described in “Sales Allowances” below.

Amounts billed to customers related to shipping and handling are classified as revenue. Shipping and handling costs are expensed as incurred and classified as cost of revenue.

Multiple performance obligations. The Company’s contracts with customers typically contain multiple performance obligations that consist of product(s) and related communications services. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The contract transaction price is then allocated to the separate performance obligations on a relative stand-alone selling price basis. The Company determines the SSP for its communications services based on observable historical stand-alone sales to customers, for which the Company requires that a substantial majority of selling prices fall within a reasonably narrow pricing range. The Company does not have a directly observable SSP for its on-premise appliance and end-point devices, and therefore establishes SSP based on its best estimates and judgments, considering company-specific factors such as pricing strategies, estimated product and other costs, and bundling and discounting practices.

Sales allowances. Credits and/or rebates issued to customers for product returns and sales incentives are deemed to be variable consideration under Topic 606, which the Company estimates and records as a reduction to revenue at the point of sale. Product returns and customer sales incentives are estimated based on the Company’s historical experience, current trends and expectations regarding future experience. Trends are influenced by product life cycles, new product introductions, market acceptance of products, the type of customer, seasonality and other factors. Product return and sales incentive rates may fluctuate over time but are sufficiently predictable to allow the Company to estimate expected future amounts. If actual future returns and sales incentives differ from past experience, additional reserves may be required. As of January 31, 2020 and 2019, the Company had total reserves for product returns and customer sales incentives of $1.4 million and $0.6 million, respectively.

Cash Equivalents and Short-term Investments. All highly liquid investments with an original maturity of three months or less at the date of purchase are classified as cash equivalents. Short-term investments are classified as available-for-sale and carried at fair value, with unrealized gains and losses, net of tax, recorded as a separate component of stockholders’ equity within accumulated other comprehensive income (loss). The cost of securities sold is based upon the specific identification method.

Fair Value of Financial Instruments. The Company records its financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. The Company estimates and categorizes the fair value of its financial assets by applying the following hierarchy:

▪

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets.

▪

Level 2: Observable prices based on inputs not quoted in active markets but are corroborated by market data.

▪

Level 3: Unobservable inputs that are supported by little or no market activity

Transfers among Level classifications are recognized as of the actual date of the events or change in circumstances that caused the transfers. The carrying value of the Company’s financial instruments, including cash equivalents, accounts receivable, inventory, accounts payable and other current assets and current liabilities approximates fair value due to their short maturities.

Concentration of Credit Risk. Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash equivalents, short-term investments, accounts receivables and other receivables. The Company’s cash equivalents and short-term investments are held by financial institutions that management believes are of high-credit quality. Such investments and deposits may, at times, exceed federally insured limits. The Company performs credit evaluations of its channel partners’ financial condition and generally does not require collateral for sales made on credit.

As of January 31, 2020, no single customer accounted for 10% or more of the Company’s net accounts receivable balance. As of January 31, 2019, one customer accounted for 15% of the Company’s net accounts receivable balance.

Accounts Receivable. Accounts receivable are stated at invoice value less estimated allowances for doubtful accounts, product returns and customer sales incentives. The Company records its allowances for doubtful accounts based upon its assessment of several factors, including historical experience, aging of receivable balances and economic conditions. As of January 31, 2020 and 2019, the Company recorded allowances for doubtful accounts of $0.2 million and $0.1 million, respectively. (See “Sales Allowances” above regarding allowances for product returns and sales incentives.)

Inventories. Inventories, which consist of raw materials and finished goods, include the cost to purchase manufactured products, allocated labor and overhead. Inventories are stated at the lower of actual cost or market on a first-in, first-out basis. The Company’s assessment of market value requires the use of estimates regarding the net realizable value of its inventory balances, including management’s assessment of excess or obsolete inventory based upon forecast demand and market conditions. Adjustments to reduce inventory to net realizable value are recognized as a component of cost of revenue in the consolidated statement of operations.

Customer Acquisition Costs. Sales commissions and other costs paid to internal sales personnel, third-party sales entities and value-added resellers are considered incremental and recoverable costs of obtaining customer contracts. (The resellers are selling agents for the Company and earn sales commissions that are directly tied to the value of the contracts that the Company enters with the end-user customers.) Beginning fiscal 2019, under Topic 606, these costs are capitalized and amortized on a systematic basis over the expected period of benefit of five years, or customer contractual term for multi-year contracts, calculated based on both qualitative and quantitative factors, such as expected subscription term and expected renewal periods of its customer contracts, product life cycles and customer attrition. Amortization expense is recorded in sales and marketing expenses in the consolidated statement of operations. Prior to fiscal 2019, such costs were expensed as incurred.

The Company pays sales commissions on initial contracts and contracts for increased purchases with existing customers (expansion contracts) and does not pay commissions for contract renewals. The Company periodically evaluates whether there have been any changes in its business, the market conditions in which it operates or other events which would indicate that its amortization period should be changed or if there are potential indicators of impairment. To date, there have been no impairment losses related to the costs capitalized.

Internal-Use Website Development Costs. The Company capitalizes certain costs to develop its websites when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Such costs primarily include payroll-related costs for engineers and contractors directly associated with the development project. Capitalized website development costs are included in property and equipment and are amortized on a straight-line basis over an estimated useful life of two years. Costs related to preliminary project activities and post-implementation activities are expensed as incurred.

Property and Equipment, net. Property and equipment, net is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is computed on a straight-line basis over the estimated useful lives of those assets, generally two to five years. Leasehold improvements are amortized over the shorter of the lease term or estimated useful lives of the respective assets. Repairs and maintenance costs that do not extend the life or improve the asset are expensed as incurred.

Operating Leases. The Company determines if an arrangement is a lease at inception. The Company’s leases primarily consist of real property and are classified as operating leases. The Company does not have any finance leases nor material arrangements as a lessor. Right-of-use lease assets and lease liabilities are recognized at the lease commencement date based upon the present value of the remaining lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. Lease terms may include options to renew or extend when it is reasonably certain that the option will be exercised. Lease agreements that contain both lease and non-lease components are accounted for as a single component. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet.

Goodwill. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is evaluated for impairment annually in the fourth quarter of its fiscal year, or more frequently if indicators of potential impairment arise. The Company has a single reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. No impairment has been recognized for any of the periods presented.

Intangible Assets. Acquired intangible assets other than goodwill, which primarily consist of developed technology and customer relationships, are amortized over their useful lives unless the lives are determined to be indefinite. For intangible assets acquired in a business combination, the estimated fair values of the assets received are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value.

Impairment of Long-Lived Assets. Long-lived assets, such as property and equipment, capitalized website development costs, and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

During fiscal 2020, the Company recorded impairment charges of $0.7 million to cost of product revenue for abandoned developed technology and trade names associated with the Ooma Smart Cam, which was acquired through the fiscal 2018 acquisition of Butterfleye, Inc. and discontinued in October 2019. See Note 15: Restructuring Charges below. The Company did not record any material impairment charges for fiscal 2019 and 2018.

Research and Development. Research and development costs, including new product development, are charged to operating expenses as incurred in the consolidated statements of operations. Research and development included personnel-related costs (including stock-based compensation), allocated costs of facilities and information technology, supplies, software tools and product certification.

Advertising. Advertising costs are included in sales and marketing and expensed as incurred, except for production costs associated with television and radio advertising, which are expensed on the first date of airing. Advertising costs were $13.6 million, $13.7 million and $14.4 million for fiscal 2020, 2019 and 2018, respectively.

Advertising payments to the Company’s channel partners recorded as a reduction in revenue totaled $0.4 million for fiscal 2020 and $0.3 million for fiscal 2019 and 2018.

Stock-Based Compensation. Stock-based compensation expense for all stock-based awards granted to employees is measured at the grant date based on the fair value of the equity award and is recognized as expense over the requisite service period, which is generally the vesting period. The fair value of options granted is estimated on the date of grant using the Black-Scholes option pricing model. The fair value of each RSU granted is determined using the fair value of the Company’s common stock on the date of grant. The fair value of each stock purchase right under the Company's ESPP is calculated based on the closing price of the Company's stock on the date of grant and the value of a call and put option is estimated using the Black-Scholes pricing model.

Income Taxes. Income taxes are recorded using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income (or loss) in the 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 rates is recognized in income in the period that includes the enactment date.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. A tax position is recognized when it is more-likely-than-not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority.

Interest and penalties associated with unrecognized tax benefits are classified as income tax expense. The Company had no interest or penalty accruals associated with uncertain tax benefits in its consolidated balance sheets and statements of operations for any periods presented.

Foreign currency. The U.S. dollar is the functional currency of the Company's foreign subsidiaries. Remeasurement and transaction gains and losses are included in interest and other income, net and were not material for any periods presented.

Note 3: Recent Accounting Standards

Adopted Accounting Standards

Leases. On February 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) which superseded the guidance in Topic 840 and required the Company to recognize operating leased assets and corresponding liabilities on the balance sheet and to provide enhanced disclosures. The Company adopted Topic 842 using the modified retrospective transition method by applying the new standard to all leases existing at the date of initial adoption and not restating comparative periods. The Company elected the package of practical expedients, which among other things, allowed it to carry forward its historical lease classification and its assessment of whether any existing leases as of the date of adoption are or contain leases.

Adoption on February 1, 2019 resulted in the recognition of $4.1 million of operating right-of-use assets and $4.3 million of operating lease liabilities on the consolidated balance sheet, with no adjustment to accumulated deficit. The difference of $0.2 million represented deferred rent for leases that existed as of the date of adoption, which was an offset to the opening balance of right-of-use assets.

Adoption of the new standard did not materially impact the Company’s consolidated statements of operations, consolidated statements of stockholders’ equity and consolidated statements of cash flows. The Company has implemented policies, processes and controls to support the standard's measurement and disclosure requirements. See Note 2: Significant Accounting Policies above and Note 7: Operating Leases below.

Accounting Standards Not Yet Adopted

Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost, which includes accounts receivables, certain financial instruments and contract assets. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. The amendment is effective for the Company beginning in fiscal 2021. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

Fair Value Measurement. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurements, which expands the disclosure requirements for Level 3 fair value measurements as well as eliminates, adds and modifies certain other disclosure requirements for fair value measurements. The amendment is effective for the Company beginning in fiscal 2021. The Company does not expect adoption to have a material impact on its consolidated financial statements.

Income Taxes. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies certain aspects of the accounting for income as well as clarifies and amends existing guidance to improve consistent application. The amendment is effective for the Company beginning fiscal 2022. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

The Company classifies its cash equivalents and short-term investments within Level 1 or Level 2 because it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value. The fair value of Level 2 financial instruments were obtained from an independent pricing service, which used quoted market prices for identical or comparable instruments or model driven valuations that used observable market data or inputs corroborated by observable market data. Commercial paper was valued using market prices, if available, adjusted for accretion of the purchase price to face value at maturity.

For the periods presented, the amortized cost of cash equivalents and marketable securities approximated their fair value and there were no material realized or unrealized gains or losses, either individually or in the aggregate. No investments in the Company’s portfolio were other-than-temporarily impaired. The Company had no material Level 3 assets or liabilities and there have been no transfers between levels.

Global Telecomm Corporation (“GTC”). In December 2018, the Company invested $1.3 million in cash to Global Telecomm Corporation, a small privately-held technology company, in exchange for an 18-month convertible promissory note, bearing interest at 10% annually, that will convert to shares of GTC common or preferred stock upon the occurrence of certain future events. The Company has partnered with GTC on certain research and development and inventory procurement activities. GTC is considered a variable interest entity (“VIE”) for accounting purposes. However, the Company is not required to consolidate GTC into its financial statements because the Company is not the primary beneficiary. As of January 31, 2020, the Company’s maximum exposure to loss was equal to the carrying value of its convertible note receivable, including accrued interest. For all periods presented, the Company held no other variable interests in VIEs.

Deferred revenue

Deferred revenue primarily consists of billings or payments received in advance of meeting revenue recognition criteria. Deferred services revenue is recognized on a ratable basis over the term of the contract as the services are provided. For all arrangements, any revenue that has been deferred and is expected to be recognized beyond one year is classified in long term liabilities on the consolidated balance sheets.

Stock Options. Under the Company's 2015 Equity Incentive Plan, or the 2015 Plan, options to purchase shares of common stock may be granted to employees, directors and consultants. These options vest from the date of grant to up to four years and expire ten years from the date of grant. Options may be exercised anytime during their term in accordance with the vesting/exercise schedule specified in the recipient’s stock option agreement and in accordance with the 2015 plan provisions.

Stock option activity for fiscal 2020 was as follows:

The weighted average grant date fair value of options granted during fiscal 2020, 2019 and 2018 was $7.13, $5.28 and $4.81 per share, respectively.

Restricted Stock Units. Under the 2015 Plan, RSUs may be granted to employees, non-employee board members and consultants. These RSUs vest ratably over a period ranging from one to four years, and are subject to the participant’s continuing service to the Company over that period. Until vested, RSUs do not have the voting and dividend participation rights of common stock and the shares underlying the awards are not considered issued and outstanding.

RSU activity for fiscal 2020 and 2019 was as follows:

	Shares (in thousands)			Weighted Average Grant-Date Fair Value Per Share
Balance as of January 31, 2018		1,967		$	8.85

Balance as of January 31, 2020		1,657		$	12.82

Vested RSUs included shares of common stock that the Company withheld on behalf of certain employees to satisfy the minimum statutory tax withholding requirements, as defined by the Company. The Company withheld an aggregate amount of $1.5 million, $2.9 million and $2.4 million in fiscal 2020, 2019 and 2018, respectively, which were classified as financing cash outflows in the consolidated statements of cash flows. The Company canceled and returned these shares to the 2015 Plan, which are available under the plan terms for future issuance.

Employee Stock Purchase Plan

The ESPP allows eligible employees to purchase shares of common stock at a discount through payroll deductions of up to 15% of their eligible compensation (subject to plan limitations). The ESPP provides for a 24-month offering period comprised of four purchase periods of approximately six months. Employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock as of the first date or the ending date of each six-month offering period. The offering periods are scheduled to start on the first trading day on or after March 15 and September 15 of each year.

During fiscal 2020, 2019 and 2018, employees purchased 0.2 million, 0.3 million and 0.3 million shares, respectively, at a weighted purchase price of $9.97, $6.82 and $5.48 per share, respectively.

Total stock-based compensation expense	$	12,761	$	10,370	$	10,921

The income tax benefit related to stock-based compensation expense was zero for all periods presented due to a full valuation allowance on the Company's deferred tax assets (see Note 10: Income Taxes below). As of January 31, 2020, there was $21.0 million of unrecognized stock-based compensation expense related to unvested RSUs, stock options and ESPP that will be recognized on a straight-line basis over the remaining weighted-average vesting period of approximately 2.4 years.

Fair value disclosures. The fair value of stock options granted and purchased under the Company's ESPP was estimated using the Black-Scholes option pricing model. The expected term of options granted to employees was based on the simplified method as the Company does not have sufficient historical exercise data, and the expected term of the ESPP was based on the contractual term. Expected volatility was determined using a combination of the average historical volatility of a group of comparable publicly traded companies and the Company’s own common stock. Risk-free interest rate was based on the yields of U.S. Treasury securities with maturities similar to the expected term. Dividend yield was zero as the Company does not have any history of, nor plans to make, dividend payments.

The fair value of employee stock options and ESPP was estimated using the Black–Scholes model with the following assumptions, as applicable:

	Fiscal Year Ended January 31,
	2020	2019	2018
Stock Options:
Expected volatility	44%	43%	47%

Income tax expense differs from the amount computed by applying the statutory federal income tax rate primarily as the result of changes in the valuation allowance. On December 22, 2017, the Tax Cuts and Jobs Act was enacted, reducing the corporate income tax rate from 35% to 21%, effective January 1, 2018.

Gross deferred tax liabilities	$	(2,182	)	$	(761	)
Total deferred tax liabilities	$	—		$	(144	)

Management believes that, based on available evidence, both positive and negative, it is more likely than not that the deferred tax assets will not be utilized, such that a full valuation allowance has been recorded. The valuation allowance for deferred tax assets was $47.8 million, $34.3 million and $28.7 million as of January 31, 2020, 2019 and 2018, respectively. The net change in the total valuation allowance for fiscal 2020 and 2019 was an increase of $13.5 million and $5.7 million, respectively.

As of January 31, 2020, the Company had approximately $121.5 million and $70.6 million of net operating loss carryforwards available to offset future taxable income for both federal and state purposes, respectively. If not utilized, these available carryforward losses will expire in various amounts for federal and state tax purposes beginning in 2030. In addition, the Company had approximately $7.9 million and $7.1 million of federal and state research and development tax credits, respectively, available to offset future taxes. If not utilized, the available federal credits will begin to expire in 2030. California state research and development tax credits can be carried forward indefinitely.

Uncertain Tax Positions

The Company has unrecognized tax benefits (“UTBs”) of approximately $6.0 million as of January 31, 2020. Deferred tax assets associated with these UTBs are fully offset by a valuation allowance. If recognized, these UTBs would not affect the effective tax rate before consideration of the valuation allowance. The following table summarizes the activity related to UTBs (in thousands):

Balance at January 31, 2018	$	2,825
Increase related to prior year positions		8
Increase related to current year tax positions		1,592
Balance at January 31, 2019		4,425
Increase related to prior year positions		—
Increase related to current year tax positions		1,592
Balance at January 31, 2020	$	6,017

The Company had no interest or penalty accruals associated with uncertain tax benefits in its balance sheets and statements of operations for both fiscal 2020 and 2019. The Company does not have any tax positions for which it is reasonably possible the total amount of gross unrecognized benefits will increase or decrease within 12 months of the year ended January 31, 2020. Because the Company has net operating loss and credit carryforwards, there are open statutes of limitations in which federal, state and foreign taxing authorities may examine the Company’s tax returns for all years from 2009 through the current period.

Commitments and Contingencies

Note 11: Commitments and Contingencies

Purchase Commitments. As of January 31, 2020 and 2019, non-cancelable purchase commitments with the Company’s contract manufacturers and other parties were $4.0 million and $4.2 million, respectively.

Legal Proceedings

In addition to the litigation matters described below, from time to time, the Company may be involved in a variety of other claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. Defending such proceedings is costly and can impose a significant burden on management and employees, the Company may receive unfavorable preliminary or interim rulings in the course of litigation, and there can be no assurances that favorable final outcomes will be obtained.

The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information. The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Legal fees are expensed in the period in which they are incurred.

As of January 31, 2020, the Company does not have any accrued liabilities recorded for loss contingencies in its consolidated financial statements.

Berks County Litigation

On January 21, 2016, the County of Berks, Pennsylvania filed a lawsuit in the Berks County Court of Common Pleas (the “Court”) naming the Company and 113 other telephone service providers as defendants (the “Berks County Litigation”), alleging breach of fiduciary duty, fraud, and negligent misrepresentation in connection with alleged violations of the Pennsylvania 911 Emergency Communication Services Act (“PA 911 Act”) for failure to collect from subscribers and remit certain fees pursuant to the PA 911 Act. On June 13, 2019, the case was dismissed by the Court and on June 26, 2019, the parties to the litigation entered into a Joint Stipulation of Dismissal, which was approved by the Court.

Deep Green Wireless Litigation

On June 8, 2016, plaintiff Deep Green Wireless LLC (“Deep Green”) filed a complaint in the U.S. District Court for the Eastern District of Texas against Ooma, Inc., alleging infringement of U.S. Patent No. RE42,714 (the “Deep Green Wireless Patent”, and such litigation, the “Deep Green Wireless Litigation”). The complaint seeks unspecified monetary damages, costs, attorneys’ fees and other appropriate relief. In February 2017, the Court granted the Company’s motion to transfer the case to the Northern District of California, which proceeding has been stayed pending the outcome of an inter partes review of the Deep Green Wireless Patent by the United States Patent Trial and Appeal Board (“PTAB”). On December 17, 2018, the PTAB issued its final decision regarding the claims at issue in the Deep Green Wireless Litigation, in which it determined that all challenged claims of the Deep Green Wireless Patent are obvious and unpatentable. On February 19, 2019, the plaintiff filed a Notice of Appeal to the Court of Appeals for the Federal Circuit. The matter was fully briefed and oral argument was held on February 7, 2020. On March 31, 2020, the Federal Circuit affirmed the final decision by the PTAB with respect to all asserted claims of the Deep Green Wireless Patent. Deep Green has 30 days to petition for rehearing by the Federal Circuit. Deep Green may also petition the Supreme Court to hear the case, provided a petition is filed on the later of 90 days from March 31, 2020 or 90 days from the date of denial of any petition for rehearing. If Deep Green does not petition for rehearing by the Federal Circuit or for the Supreme Court to hear the case, or if the petition for rehearing is denied, we expect the Deep Green Wireless Litigation will be dismissed.

Based on the Company’s current knowledge, the Company has determined that the amount of any material loss or range of any losses that is reasonably possible to result from the Deep Green Wireless Litigation is not estimable.

Oregon Tax Litigation

On August 30, 2016, the Oregon Department of Revenue (the “DOR”) issued tax assessments against the Company for the Oregon Emergency Communications Tax (the “Tax”), which the DOR alleges Ooma should have collected from its subscribers in Oregon and remitted to the DOR during the period between January 1, 2013 and March 31, 2016 (collectively, the “Assessments”).

The Company believes that the Commerce Clause of the United States Constitution bars the application of the Tax and the Assessments to the Company, since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Oregon. On January 17, 2019, the Regular Division of the Oregon Tax Court heard oral arguments on the parties’ cross motions for summary judgment. During fiscal 2019, the Company paid $0.6 million to the State of Oregon in connection with the Oregon Tax Litigation, of which $0.3 million was charged to the consolidated statement of operations as the amount of loss deemed probable and reasonably estimable, and $0.3 million was recorded as a receivable in other current assets on the consolidated balance sheet for interest and penalties. As of January 31, 2020, the Company determined the $0.3 million receivable was not probable of recovery and charged the amount to general and administrative expense in the consolidated statement of operations.

On March 2, 2020, Oregon Tax Court issued a decision upholding the Assessments. On April 1, 2020, the Company filed a Notice of Appeal with the Supreme Court of the State of Oregon. However, litigation is unpredictable and there can be no assurances that the Company will obtain a favorable final outcome or that it will be able to avoid further unfavorable interim rulings in the course of litigation that may significantly add to the expense of its defense and could result in substantial costs and diversion of resources.

Securities Litigation

On January 14, 2016, Michael Barnett filed a purported stockholder class action in the San Mateo County Superior Court of the State of California (Case No. CIV536959) against the Company, certain of its officers and directors, and certain of the underwriters of the Company’s IPO on July 17, 2015. After the case was consolidated with two other identical lawsuits, a “consolidated complaint” was filed on behalf of all persons who purchased shares of common stock in the Company’s IPO in reliance upon the Registration Statement and Prospectus the Company filed with the SEC. The consolidated complaint alleged that the Company and the other defendants violated the Securities Act of 1933, as amended (the “Securities Act”) by issuing the Registration Statement and Prospectus, which the plaintiffs alleged contained material misstatements and omissions in violation of Sections 11, 12(a)(2) and 15 of the Securities Act.

On May 30, 2019, the parties filed with the Court a Stipulation of Settlement, and on October 18, 2019 the Court entered final approval of the settlement. Under the terms of the settlement, the Company’s directors’ and officers’ liability insurers deposited $8.65 million into a settlement fund for payment to class members, and paid plaintiff’s attorneys’ fees and costs of administering the settlement. The Stipulation of Settlement contains no admissions of wrongdoing, and the Company and the other defendants have maintained and continue to deny liability and wrongdoing of any kind with respect to the class action claims. As part of the final settlement approval, the Court dismissed the class action lawsuit with prejudice and the plaintiff released all claims against the Company and all other defendants relating to the allegations in the class action.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for certain losses suffered or incurred by the indemnified party. In some cases, the term of these indemnification agreements is perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future but have not yet been made.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid.

To date the Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with such indemnifications has been recorded to date.

Business Acquisitions

Note 12: Business Acquisitions

Broadsmart Global, Inc.

On May 24, 2019, the Company acquired all outstanding stock of Broadsmart, a provider of cloud-based UCaaS solutions based in Florida. The cash consideration transferred for Broadsmart was $7.1 million, net of cash assumed of $0.6 million, and of which approximately $0.9 million will be held in escrow for a period of up to two years. The Company expects Broadsmart will provide scale for the Ooma Office and Ooma Enterprise platforms, which aligns with the Company’s overall enterprise growth strategy.

The fair values of assets acquired and liabilities assumed as of the date of acquisition was as follows (in thousands):

	Fair Value
Cash	$	649
Accounts receivable		1,003
Other current and non-current assets		639
Intangible assets		6,107
Goodwill		366
Accounts payable and other liabilities		(1,043	)
Net assets acquired	$	7,721

Intangible assets acquired consisted of customer relationships of $5.8 million and trade names of $0.3 million. Customer relationships represented the estimated fair values of the underlying relationships with Broadsmart’s customer base and have an estimated useful life of seven years as of the date of acquisition. The goodwill recognized was attributable to the assembled workforce and expanded market opportunities when integrating Broadsmart’s offerings with Ooma Business. The Company made an election under Section 338(h)(10) of the Internal Revenue Code, which resulted in the acquisition being treated as an asset purchase for income tax purposes. Therefore, the transaction did not result in the recording of deferred taxes as the Company's tax basis in the acquired assets equaled its book basis. The resulting goodwill from this acquisition is deductible for U.S. income tax purposes.

Broadsmart revenue included in the Company’s consolidated statement of operations from the May 24, 2019 acquisition date through January 31, 2020 was approximately $7.0 million. On an unaudited pro forma basis, had the Broadsmart acquisition been included in the Company’s consolidated results of operations beginning February 1, 2018, the Company’s total revenue for fiscal 2020 and 2019 would have approximated $153 million and $138 million, respectively. These pro forma revenue amounts were adjusted to exclude revenue associated with a legacy Broadsmart customer that was not expected to be a continuing customer for the combined entity. These pro forma revenue amounts do not necessarily represent what would have occurred if the business combination had taken place on February 1, 2018, nor do these amounts represent the results that may occur in the future. Actual and pro forma net loss for the Broadsmart acquisition have not been presented because the impact was not material to the Company's consolidated statement of operations.

Acquisition-related transaction costs charged to expense during fiscal 2020 were approximately $0.3 million.

Voxter Communications, Inc.

On March 12, 2018, the Company acquired all outstanding stock of Voxter, a privately-held provider of UCaaS offerings for mid-market and enterprise businesses. The acquisition date fair value consideration transferred for Voxter was approximately $3.9 million, which primarily consisted of cash and common stock. The final purchase price allocation included identifiable intangible assets of approximately $2.1 million, net assets acquired of approximately $0.4 million, deferred tax liabilities of approximately $0.4 million and residual goodwill of approximately $2.0 million, based on the best estimates of management. Acquisition-related transaction costs charged to expense were $0.4 million. The goodwill recognized was attributable primarily to expected synergies in the acquired technologies that may be leveraged by the Company in future Ooma Business offerings. Goodwill was not deductible for U.S. or Canadian income tax purposes.

The operating results of the acquired company were included in the Company's consolidated financial statements from the date of acquisition. Actual and pro forma results of operations for the Voxter acquisition have not been presented because it does not have a material impact on the Company's consolidated results of operations.

Earnings Per Share [Abstract]

Net Loss Per Share

Note 13: Net Loss Per Share

Basic and diluted net loss per share of common stock is calculated by dividing the net loss allocable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per share of common stock is the same as basic net loss per share because the effects of potentially dilutive securities are antidilutive because the Company reported net losses for all periods presented.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except share and per share data):

	Fiscal Year Ended January 31,
	2020			2019			2018
Numerator
Net loss	$	(18,801	)	$	(14,572	)	$	(13,121	)
Denominator
Weighted-average common shares		21,051,039			19,799,781			18,570,128
Basic and diluted net loss per share	$	(0.89	)	$	(0.74	)	$	(0.71	)

Potentially dilutive securities of approximately 3.2 million, 3.9 million and 4.1 million were excluded from the computation of diluted net loss per share for fiscal 2020, 2019 and 2018, respectively. These dilutive securities included the Company’s RSUs, stock options and shares to be purchased under the ESPP. These shares include the Company’s outstanding RSUs, outstanding stock options and shares to be purchased under the ESPP at the end of the respective period. In the event the Company reported net income for the periods presented, a portion of these outstanding securities would be reflected in weighted-average shares outstanding for diluted earnings per share by application of the treasury method.

Restructuring Charges

Note 15: Restructuring Charges

In October 2019, the Company approved a restructuring plan designed to better align resources around its long-term business strategy. The restructuring provided for the discontinuation of Ooma Smart Cam, given the increased level of competition in the market, accompanied with a small reduction-in-force.

For fiscal 2020, the Company recorded aggregate restructuring charges of $3.1 million in its consolidated statement of operations, which consisted of the following major components (in thousands):
