Overview and Basis of Presentation

Note 1: Overview and Basis of Presentation

Ooma, Inc. and its wholly-owned subsidiaries (collectively, “Ooma” or the “Company”) provides leading communications services and related technologies for businesses and consumers, delivered from its smart cloud-based SaaS and unified communications platforms. The Company is headquartered in Sunnyvale, California.

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 in 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 2022, fiscal 2021 and fiscal 2020 refer to the fiscal years ended January 31, 2022, January 31, 2021 and January 31, 2020, 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. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, deferred sales commissions, valuation of goodwill and intangible assets, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation and income taxes (including valuation allowances). The Company bases its estimates and assumptions on historical experience, where applicable, and other factors that it believes to be reasonable under the circumstances. These estimates are based on information available as of the date of the consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s 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, who reviews the Company’s 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 a single reportable segment.

Revenue was principally derived from customers located in the United States for all periods presented, with a small portion attributable to customers located in Canada and other countries. Long-lived assets located outside of the United States were not significant.

Note 2: Significant Accounting Policies

Revenue Recognition

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 “channel partners”), and Ooma sales representatives.

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

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. Service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. Subscription revenue is generally recognized ratably over the contractual service term. A small portion of total revenue is recognized 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 primarily from the sale of on-premise devices and end-point devices, and to a lesser extent from porting fees that enable customers to transfer their existing phone numbers. The Company recognizes product and other 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. The Company’s distribution agreements with channel partners typically contain clauses for price protection and right of return. Credits and/or rebates issued for expected product returns and customer sales incentives are deemed to be variable consideration, which the Company estimates and records as a reduction to revenue at the point of sale. Product returns and sales incentives are estimated based on the Company’s historical experience, current trends and expectations regarding future experience. As of January 31, 2022 and 2021, total reserves for product returns and sales incentives were approximately $1.2 million and $1.1 million, respectively.

Revenue is recorded net of any sales and telecommunications taxes collected from customers to be remitted to government authorities. Amounts billed to customers related to shipping and handling are classified as product and other 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 communications services and related product(s). For these contracts, individual performance obligations are accounted for 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 a substantial majority of selling prices must fall within a reasonably narrow pricing range. The Company determines the SSP for its on-premise devices and end-point devices based upon management’s best estimates and judgments, considering company-specific factors such as pricing strategies, discounting practices, and estimated product and other costs.

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 (loss) income. 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

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.

Concentrations. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable and convertible note receivable (Note 5). The Company’s cash, cash equivalents and short-term investments are held by financial institutions that management believes are of high-credit quality although the balances, at times, may exceed federally insured limits. The Company performs credit evaluations of its customers’ financial condition and generally does not require collateral for sales made on credit.

Customers who represented 10% or more of net accounts receivable were as follows:

	As of
	January 31, 2022	January 31, 2021
Customer A	19%	*
Customer B	11%	*
Customer C	*	10%

*As of January 31, 2022 and 2021, these customers accounted for less than 10% of net accounts receivable.

Accounts Receivable. Accounts receivable are recorded net of an allowance for doubtful accounts for estimated credit losses. Allowances are recorded based upon assessment of several factors, including historical experience, aging of receivable balances and economic conditions. As of January 31, 2022 and 2021, the allowance for doubtful accounts was $0.3 million. Bad debt expense recorded in the consolidated statement of operations was not material for the periods presented.

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 and net realizable value on a first-in, first-out basis. The Company writes down the carrying value of inventory to net realizable value for estimated excess and obsolete inventory based upon assumptions about forecast demand and market conditions. Inventory carrying value adjustments are recognized as a component of cost of product and other 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. 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. The Company has determined the period of benefit taking into consideration 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.

The Company pays sales commissions on initial contracts, contracts for increased purchases with existing customers (expansion contracts) and certain 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 material impairment losses related to the costs capitalized.

Internal-Use Website Development Costs. The Company capitalizes certain costs to develop its customer-facing 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 office and data center space 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. The accounting lease term 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. The Company evaluates goodwill 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 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.

The Company did not record any material impairment charges for fiscal 2022 or fiscal 2021. 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.

Research and Development. Research and development costs are charged to operating expenses as incurred in the consolidated statements of operations, except for internal-use website development costs that qualify for capitalization, as per above. Research and development expenses consist primarily of personnel-related costs for employees and contractors, including stock-based compensation, as well as license and product certification fees and allocated overhead costs.

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 $14.5 million, $12.2 million and $13.6 million for fiscal 2022, 2021 and 2020, respectively.

Advertising payments to the Company’s channel partners recorded as a reduction in revenue totaled $0.3 million, $0.3 million and $0.4 million for fiscal 2022, 2021 and 2020, respectively.

Stock-Based Compensation. Stock-based compensation expense for all stock-based awards granted to employees and non-employee directors are measured at the grant date fair value of the equity award. The fair value of options granted and purchase rights under the Company’s ESPP are estimated on the date of grant using the Black-Scholes pricing model. The fair value of each RSU granted is determined using the closing market price of the Company’s common stock on the date of grant. Compensation expense is recognized using the straight-line method over the requisite service period, which is generally the vesting period. Forfeitures are recorded in the period in which they occur.

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 (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.

Adopted Accounting Standards

Financial Instruments-Credit Losses. On February 1, 2021, the Company adopted Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplified certain aspects of the accounting for income taxes as well as clarified and amended existing guidance to improve consistent application. Adoption did not have a material impact on the Company’s consolidated financial statements and related disclosures.

Customer Acquisition Costs. Amortization expense for total deferred sales commissions was $6.0 million, $3.9 million and $2.2 million for fiscal 2022, 2021 and 2020, respectively.

Global Telecom Corporation (“GTC”). In December 2018, the Company invested $1.3 million in cash in GTC, a privately-held technology company, in exchange for a convertible promissory note that will convert to shares of GTC stock upon the occurrence of certain future events. As amended, the promissory note and accrued interest is due and payable upon the Company’s demand at any time after June 30, 2022. The Company has also partnered with GTC on certain inventory procurement and research and development activities. GTC is a variable interest entity for accounting purposes and the Company does not consolidate GTC into its financial statements because the Company is not the primary beneficiary. The Company’s maximum exposure to loss is equal to the carrying value of the convertible note receivable, including accrued interest. During fiscal 2022, the Company made total payments to GTC of approximately $2.7 million for inventory purchases and related shipping costs. As of January 31, 2022 and 2021, the Company’s non-cancelable inventory purchase commitments to GTC were immaterial.

Leases [Abstract]

Operating Leases

Note 7: Operating Leases

The Company leases its headquarters located in Sunnyvale, California, as well as office and data center space in several locations under non-cancelable operating lease agreements, with expiration dates through fiscal 2030. The lease agreements often include escalating rent payments, renewal provisions and other provisions which require the Company to pay common area maintenance costs, property taxes and insurance. The lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Operating lease right-of-use assets and long-term operating lease liabilities are included on the face of the consolidated balance sheet. Short-term operating lease liabilities are presented within accrued expenses and other current liabilities.

Supplemental balance sheet information related to leases was as follows (in thousands):

(1) Recognized on a straight-line basis over the lease term. Includes rent for leases with initial terms of twelve months or less, which were not material.

(2) Primarily included common area maintenance, utilities and property taxes and insurance, which were expensed as incurred.

Effective May 2021, the Company extended the sublease term for its corporate headquarters in Sunnyvale, California from an end date of January 31, 2022 to March 15, 2029. The total undiscounted rental payments associated with the sublease extension are approximately $11.1 million from February 2022 onwards. The Company is also required to continue paying common area maintenance costs, property taxes and insurance. This sublease extension is a lease modification that qualifies as a change of accounting for the original sublease and not a separate contract. Accordingly, in the second quarter of fiscal 2022, the Company remeasured its operating lease liability using the present value of the revised rental payments and recognized the difference of $9.5 million between the new lease liability and the old lease liability as an increase to the operating lease right-of-use asset.

Shares reserved under ESPP		1,370		1,131
Total shares reserved for issuance		6,361		5,825

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, non-employee 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 2022 was as follows:

				Weighted-Average		Aggregate
	Shares			Exercise Price		Intrinsic Value
	(in thousands)			Per Share		(in thousands)
Balance as of January 31, 2021		1,366		$	7.95	$	7,803
Granted		120		$	16.28
Exercised		(125	)	$	3.81
Canceled		(36	)	$	13.79
Balance as of January 31, 2022		1,325		$	8.93	$	12,064
Vested and exercisable as of January 31, 2022		1,152		$	8.18	$	11,363

The aggregate intrinsic value of vested options exercised during fiscal 2022, 2021 and 2020 was $1.9 million, $1.4 million and $2.2 million, respectively. The weighted-average grant date fair value of options granted during fiscal 2022, 2021 and 2020 was $7.89, $4.72 and $7.13, respectively.

Restricted Stock Units. Under the 2015 Plan, RSUs may be granted to employees, non-employee directors 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 2022 was as follows:

	Shares (in thousands)			Weighted-Average Grant-Date Fair Value Per Share
Balance as of January 31, 2021		1,441		$	12.54
Granted		919		$	17.04
Vested		(824	)	$	13.19
Canceled		(224	)	$	13.93
Balance as of January 31, 2022		1,312		$	15.05

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 $2.1 million, $1.6 million and $1.5 million in fiscal 2022, 2021 and 2020, 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 each of the fiscal years 2022, 2021 and 2020, employees purchased 0.2 million shares at a weighted-average purchase price of $10.22, $9.98 and $9.97 per share, respectively.

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock-Based Compensation

Stock-Based Compensation

Note 9: Stock-Based Compensation

Total stock-based compensation recognized for stock-based awards in the consolidated statements of operations was as follows (in thousands):

	Fiscal Year Ended January 31,
	2022		2021		2020
Cost of revenue	$	979	$	1,015	$	1,262
Sales and marketing		1,856		1,910		1,929
Research and development		4,216		4,267		4,610
General and administrative		5,631		5,083		4,960
Total stock-based compensation expense	$	12,682	$	12,275	$	12,761

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, 2022, there was $19.0 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 2.5 years.

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

	Fiscal Year Ended January 31,
	2022	2021	2020
Stock Options:
Expected volatility	51%	47%	44%
Expected term (in years)	6.1	6.1	6.1
Risk-free interest rate	0.9%	0.6%	2.5%
Dividend yield	NA	NA	NA

	Fiscal Year Ended January 31,
	2022	2021	2020
ESPP:
Expected volatility	41%-58%	46%-83%	40%-51%
Expected term (in years)	0.5-2.0	0.5-2.0	0.5-2.0
Risk-free interest rate	0.1%-0.2%	0.1%-0.4%	1.7%-2.5%
Dividend yield	NA	NA	NA

The expected term of options granted to employees is based on the simplified method as the Company does not have sufficient historical exercise data, and the expected term of the ESPP is based on the contractual term. For fiscal 2022, expected volatility is derived from the average historical volatility of the Company’s own common stock. In prior fiscal years, expected volatility was derived from a combination of the average historical volatility of the Company’s own common stock and a group of comparable publicly traded companies. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term.

The tax effects of temporary differences that give rise to significant portions of the Company’s deferred tax assets and liabilities are as follows (in thousands):

	As of January 31,
	2022			2021
Deferred tax assets:
Net operating loss carryforwards	$	34,808		$	33,211
Tax credit carryover		10,905			8,963
Operating lease right-of-use assets		3,482			1,686
Stock-based compensation		1,114			1,101
Acquired intangible assets		256			53
Deferred revenue		18			19
Other		26			14
Gross deferred tax assets		50,609			45,047
Valuation allowance		(45,111	)		(42,153	)

Deferred tax liabilities:

Accruals and reserves		(1,994	)		(1,265	)
Fixed assets depreciation		(36	)		(96	)
Gross deferred tax liabilities	$	(5,498	)	$	(2,894	)
Net deferred taxes	$	—		$	—

Management believes that, based upon the 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 net change in the total valuation allowance for fiscal 2022 and 2021 were increases of $3.0 million and $0.6 million, respectively.

As of January 31, 2022, the Company had net operating loss carryforwards for federal and state tax purposes of approximately $125.1 million and $94.8 million, respectively, available to offset future taxable income. 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 research and development tax credits for federal and state purposes of approximately $10.5 million and $9.8 million, 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.

Immaterial Corrections of Prior Period Disclosures. Subsequent to the Company’s filing of its Annual Report on Form 10-K for the year ended January 31, 2021, the Company identified certain errors relating to its presentation of deferred tax assets, specifically net operating loss carryforwards and the associated valuation allowance for state tax purposes. As a result, the previously reported net operating loss carryforwards deferred tax asset and the valuation allowance were each reduced by $7.4 million. These corrections had no impact on the Company’s income tax provision (benefit) reported in the consolidated statements of operations and no impact on net deferred taxes in the consolidated balance sheet as of and for the year ended January 31, 2021. The Company has evaluated the materiality of these errors based on an analysis of quantitative and qualitative factors and concluded they were not material to the prior period financial statements, individually or in the aggregate.

Uncertain Tax Positions

The Company has unrecognized tax benefits of approximately $8.1 million as of January 31, 2022. Deferred tax assets associated with these unrecognized tax benefits are fully offset by a valuation allowance. If recognized, these benefits would not affect the effective tax rate before consideration of the valuation allowance.

The following table summarizes the activity related to unrecognized tax benefits (in thousands):

Balance at January 31, 2020	$	6,017
Decrease related to prior year positions		(362	)
Increase related to current year tax positions		987
Balance at January 31, 2021		6,642
Increase related to current year tax positions		1,448
Balance at January 31, 2022	$	8,090

The Company had no interest or penalty accruals associated with uncertain tax benefits in its balance sheets and statements of operations. 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, 2022.

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 tax years from 2009 through the current period.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Commitments and Contingencies

Note 11: Commitments and Contingencies

Purchase Commitments

As of January 31, 2022 and 2021, non-cancelable inventory purchase commitments to contract manufacturers and other parties were approximately $19.4 million and $5.4 million, respectively.

Additionally, the Company has a non-cancelable service agreement with a telecommunications provider that contains total annual minimum purchase commitments of $0.6 million between August 2021 and July 2022, $1.5 million between August 2022 and July 2023 and $2.5 million between August 2023 and July 2024.

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, 2022 and 2021, the Company does not have any accrued liabilities recorded for loss contingencies in its consolidated financial statements.

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 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 and on December 23, 2021, the Supreme Court of Oregon issued a decision upholding the assessment. The Company intends to file a petition for writ of certiorari with the United States Supreme Court. Litigation is unpredictable and there can be no assurances that the Company will obtain a favorable final outcome, even assuming the United States Supreme Court grants the Company’s petition. In prior fiscal years, the Company recorded and has paid cumulative charges of $0.6 million to the DOR as its best estimate of probable loss related to the Assessments.

Canadian Litigation

On February 3, 2021, plaintiff Fiona Chiu filed a class action complaint against the Company and Ooma Canada Inc. in the Federal Court of Canada, alleging violations of Canada’s Trademarks Act and Competition Act. The complaint seeks monetary and other damages and/or injunctive relief enjoining the Company to cease describing and marketing its Basic Home Phone using the word “free” or otherwise representing that it is free. On November 9, 2021, the Federal Court of Canada removed Ms. Chiu and substituted John Zanin as the new plaintiff in the proceeding. In connection with the substitution of Mr. Zanin as the new plaintiff, the Federal Court of Canada deemed the proceeding as having commenced on November 8, 2021 instead of February 3, 2021. During the week of January 17, 2022, the Federal Court of Canada heard arguments from counsel representing each of the Company and Mr. Zanin regarding jurisdiction and class action certification issues, and the parties are awaiting the Court to issue its ruling. The Company intends to continue to defend itself vigorously against this complaint. Based on the Company’s current knowledge, the Company has determined that the amount of any reasonably possible loss resulting from the Canadian Litigation is not estimable.

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.

Financing Arrangements

Note 12: Financing Arrangements

Revolving Credit Facility

On January 8, 2021, the Company, as borrower, entered into a three year credit and security agreement (“Credit Agreement”) with KeyBank National Association as Administrative Agent (“Agent”) and lender, and KeyBanc Capital Markets Inc. as sole lead arranger and sole book runner. The Credit Agreement provides for a secured revolving credit facility (“Credit Facility”) under which the Company may borrow up to an aggregate amount of $25.0 million, which includes a $10.0 million sub-facility for letters of credit. The Company and its lenders may increase the total commitments under the Credit Facility to up to an aggregate amount of $45.0 million, subject to certain conditions. Funds borrowed under the Credit Agreement may be used for working capital and other general corporate purposes.

Loans under the Credit Agreement will bear interest, at the Company’s option, at either a rate equal to the “Base Rate” (as defined in the Credit Agreement) or (b) “Eurodollar Rate” (as defined in the Credit Agreement) plus 2.50%. The Base Rate is the highest of (i) the Agent’s prime rate, (ii) the federal funds effective rate plus 0.5%, and (iii) the Eurodollar Rate with an interest period of one month plus 1%. The Eurodollar Rate is the London Interbank Offered Rate with various interest periods as may be selected by the Company but shall not be less than 0.75%. Upon the occurrence of any event of default, the interest rate on any borrowings increases by 2.0%. The Credit Agreement also contains customary provisions for the replacement of the London Interbank Offered Rate/Eurodollar Rate. The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% per annum.

The Credit Agreement contains customary representations, warranties, affirmative and negative covenants, events of default and indemnification provisions in favor of the Agent, lenders and their affiliates. Among other covenants, the Credit Agreement includes restrictive financial covenants that require the Company to meet minimum recurring revenue levels and maintain specified amounts of available liquidity on a quarterly basis.

As of January 31, 2022, the Company had zero outstanding borrowings and was in compliance with the covenants contained in the Credit Agreement. Accordingly, $25.0 million of borrowing capacity was available for the purposes permitted by the Credit Agreement.

Business Acquisitions

Note 13: 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. The Company acquired Broadsmart to 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. The acquisition of Broadsmart was treated as an asset purchase for income tax purposes, and 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 was deductible for U.S. income tax purposes.

Net Loss Per Share

Earnings Per Share [Abstract]

Net Loss Per Share

Note 14: 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,
	2022			2021			2020
Numerator
Net loss	$	(1,751	)	$	(2,441	)	$	(18,801	)
Denominator
Weighted-average common shares		23,473,849			22,361,312			21,051,039
Basic and diluted net loss per share	$	(0.07	)	$	(0.11	)	$	(0.89	)

Potentially dilutive securities of approximately 2.8 million, 3.3 million and 3.2 million were excluded from the computation of diluted net loss per share for fiscal 2022, 2021 and 2020, respectively. 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 purchase 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.

Borrowing capacity description				On January 8, 2021, the Company, as borrower, entered into a three year credit and security agreement (“Credit Agreement”) with KeyBank National Association as Administrative Agent (“Agent”) and lender, and KeyBanc Capital Markets Inc. as sole lead arranger and sole book runner. The Credit Agreement provides for a secured revolving credit facility (“Credit Facility”) under which the Company may borrow up to an aggregate amount of $25.0 million, which includes a $10.0 million sub-facility for letters of credit. The Company and its lenders may increase the total commitments under the Credit Facility to up to an aggregate amount of $45.0 million, subject to certain conditions. Funds borrowed under the Credit Agreement may be used for working capital and other general corporate purposes.
Credit agreement, Interest rate description			Loans under the Credit Agreement will bear interest, at the Company’s option, at either a rate equal to the “Base Rate” (as defined in the Credit Agreement) or (b) “Eurodollar Rate” (as defined in the Credit Agreement) plus 2.50%. The Base Rate is the highest of (i) the Agent’s prime rate, (ii) the federal funds effective rate plus 0.5%, and (iii) the Eurodollar Rate with an interest period of one month plus 1%. The Eurodollar Rate is the London Interbank Offered Rate with various interest periods as may be selected by the Company but shall not be less than 0.75%. Upon the occurrence of any event of default, the interest rate on any borrowings increases by 2.0%. The Credit Agreement also contains customary provisions for the replacement of the London Interbank Offered Rate/Eurodollar Rate. The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% per annum.
