Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the consolidated financial statements.

The Company believes that a significant accounting policy is one that is both important to the portrayal of the Company’s financial condition and results, and requires management’s most difficult, subjective, or complex judgments, often as the result of the need to make estimates about the effect of matters that are inherently uncertain.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (ASC) and Accounting Standards Update (ASU) of the Financial Accounting Standards Board (FASB).

Use of Estimates and Uncertainties

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts expensed during the reporting period.

Significant estimates relied upon in preparing these consolidated financial statements include revenue recognition and revenue reserves, contingent liabilities, intangible asset valuations, amortization periods, expected future cash flows used to evaluate the recoverability of long-lived assets, the determination of the fair value of stock awards issued, and the recoverability of the Company’s deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made.

The Company is subject to a number of risks and uncertainties common to companies in similar industries and stages of development including, but not limited to, rapid technological changes, competition from substitute products and services from larger companies, customer concentration, management of international activities, protection of proprietary rights, patent litigation, and dependence on key individuals.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Subsequent Events Considerations

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. The Company has evaluated all subsequent events and determined that, other than as reported herein and described below, there are no material recognized or unrecognized subsequent events.

On February 13, 2019, the Company entered into a definitive agreement to acquire a significant portion of the assets of Ooyala, Inc. and certain of its subsidiaries, or “Ooyala”, a provider of cloud video ad insertion technology, in exchange for 1,056,763 unregistered shares of common stock of Brightcove Inc. and approximately $6.25 million of cash, which includes up to $500 as a reimbursement of Ooyala’s audit fees incurred in connection with the transaction. Pursuant to the purchase agreement, approximately $2.65 million of the cash will be placed into an escrow account to settle certain claims for indemnification for breaches or inaccuracies in Ooyala’s representations and warranties, covenants, and agreements. The escrow amount is the equivalent of 18% of the purchase price, and this amount will remain in escrow for 20 months. The expected acquisition will be accounted for as a purchase transaction, and as such the results of operations from the acquired assets will be consolidated with the Company beginning on the closing date of the acquisition. In connection with the acquisition of Ooyala, the Company incurred $716 of merger-related costs during 2018, which the Company recorded as an expense in its consolidated statements of operations for the year ended December 31, 2018. At this time, the Company has not completed its evaluation of the purchase accounting related to this transaction.

Foreign Currency Translation

The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s foreign subsidiaries is the local currency of each subsidiary. All assets and liabilities in the balance sheets of entities whose functional currency is a currency other than the U.S. dollar are translated into U.S. dollar equivalents at exchange rates as follows: (1) asset and liability accounts at period-end rates, (2) income statement accounts at weighted-average exchange rates for the period, and (3) stockholders’ equity accounts at historical exchange rates. The resulting translation adjustments are excluded from income (loss) and reflected as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in net loss for the period. The Company may periodically have certain intercompany foreign currency transactions that are deemed to be of a long-term investment nature; exchange adjustments related to those transactions are made directly to a separate component of stockholders’ equity.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Management determines the appropriate classification of investments at the time of purchase, and re-evaluates such determination at each balance sheet date. The Company did not have any short-term or long-term investments at December 31, 2018 or 2017.

Cash and cash equivalents primarily consist of cash on deposit with banks and amounts held in interest-bearing money market accounts. Cash equivalents are carried at cost, which approximates their fair market value.

Cash and cash equivalents as of December 31, 2018 and 2017 consist of the following:


	December 31, 2018
Description	Contracted Maturity		Amortized Cost		Fair Market Value		Balance Per Balance Sheet
Cash		Demand	$	21,007	$	21,007	$	21,007
Money market funds		Demand		8,299		8,299		8,299

Total cash and cash equivalents			$	29,306	$	29,306	$	29,306


	December 31, 2017
Description	Contracted Maturity		Amortized Cost		Fair Market Value		Balance Per Balance Sheet
Cash		Demand	$	17,972	$	17,972	$	17,972
Money market funds		Demand		8,160		8,160		8,160

Total cash and cash equivalents			$	26,132	$	26,132	$	26,132

Disclosure of Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash, cash equivalents, accounts receivable, accounts payable, accrued expenses, capital lease liabilities and equipment financing, approximated their fair values at December 31, 2018 and 2017, due to the short-term nature of these instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information and management’s estimates. The use of different market assumptions and/or estimation methodologies could have a significant impact on the estimated fair value amounts. See Note 5 for further discussion.

Revenue

The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which was adopted on January 1, 2018 using the applied the modified retrospective method. For further discussion of the Company’s accounting policies related to revenue, see Note 3.

Cost of Revenue

Cost of revenue primarily consists of costs related to supporting and hosting the Company’s product offerings and delivering professional services. These costs include salaries, benefits, incentive compensation and stock-based compensation expense related to the management of the Company’s data centers, customer support team and the Company’s professional services staff, in addition to third-party service provider costs such as data center and networking expenses, allocated overhead, amortization of capitalized internal-use software development costs and intangible assets and depreciation expense.

Allowance for Doubtful Accounts

The Company offsets gross trade accounts receivable with an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable and is based upon historical loss patterns, the number of days that billings are past due, and an evaluation of the potential risk of loss associated with specific accounts. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for allowances for doubtful accounts are recorded in general and administrative expense.

Below is a summary of the changes in the Company’s allowance for doubtful accounts for the years ended December 31, 2018, 2017 and 2016:


	Balance at Beginning of Period		Provision		Write-offs			Balance at End of Period
Year ended December 31, 2018	$	146	$	199	$	(155	)	$	190
Year ended December 31, 2017		154		203		(211	)		146
Year ended December 31, 2016		332		230		(408	)		154

Off-Balance Sheet Risk and Concentration of Credit Risk

The Company has no significant off-balance sheet risk, such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents and trade accounts receivable. The Company maintains its cash and cash equivalents principally with accredited financial institutions of high credit standing. Although the Company deposits its cash with multiple financial institutions, its deposits, at times, may exceed federally insured limits. The Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable.

For the years ended December 31, 2018, 2017 and 2016, no individual customer accounted for more than 10% of total revenue. As of December 31, 2018 and 2017, no individual customer accounted for more than 10% of accounts receivable, net.

Concentration of Other Risks

The Company is dependent on certain content delivery network providers who provide digital media delivery functionality enabling the Company’s on-demand application service to function as intended for the Company’s customers and ultimate end-users. The disruption of these services could have a material adverse effect on the Company’s business, financial position, and results of operations.

Software Development Costs

Costs incurred to develop software applications used in the Company’s on-demand application services consist of (a) certain external direct costs of materials and services incurred in developing or obtaining internal-use computer software, and (b) payroll and payroll-related costs for employees who are directly associated with, and who devote time to, the project. These costs generally consist of internal labor during configuration, coding, and testing activities. Research and development costs incurred during the preliminary project stage or costs incurred for data conversion activities, training, maintenance and general and administrative or overhead costs are expensed as incurred. Capitalization begins when the preliminary project stage is complete, management, with the relevant authority, authorizes and commits to the funding of the software project, it is probable the project will be completed, the software will be used to perform the functions intended and certain functional and quality standards have been met. Qualified costs incurred during the operating stage of the Company’s software applications relating to upgrades and enhancements are capitalized to the extent it is probable that they will result in added functionality, while costs that cannot be separated between maintenance of, and minor upgrades and enhancements to, internal-use software are expensed as incurred. These capitalized costs are amortized on a straight-line basis over the expected useful life of the software, which is estimated to be three years. Capitalized internal-use software development costs are classified as “Software” within “Property and Equipment, net” in the accompanying consolidated balance sheets.

During the years ended December 31, 2018, 2017 and 2016, the Company capitalized $3,152, $3,239 and $4,038, respectively, of internal-use software development costs. The Company recorded amortization expense associated with its capitalized internal-use software development costs of $2,962, $1,867 and $690 for the years ended December 31, 2018, 2017 and 2016, respectively.

Property and Equipment

Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Upon retirement or sale, the cost of assets disposed of, and the related accumulated depreciation, are removed from the accounts, and any resulting gain or loss is included in the determination of net income or loss in the period of retirement.

Property and equipment consists of the following:


	Estimated Useful Life (in Years)		December 31,
			2018		2017
Computer equipment		3	$	14,076	$	17,157
Software		3 - 6		21,208		17,996
Furniture and fixtures		5		2,929		2,396
Leasehold improvements		Shorter of lease term or the estimated useful life		1,665		1,366

				39,878		38,915
Less accumulated depreciation and amortization				30,175		29,772

			$	9,703	$	9,143

Depreciation and amortization expense, which includes amortization expense associated with capitalized internal-use software development costs, for the years ended December 31, 2018, 2017 and 2016 was $4,479, $4,523 and $4,860, respectively.

Expenditures for maintenance and repairs are charged to expense as incurred, whereas major improvements are capitalized as additions to property and equipment.

Long-Lived Assets

The Company reviews long-lived assets and certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During this review, the Company re-evaluates the significant assumptions used in determining the original cost and estimated lives of long-lived assets. Although the assumptions may vary from asset to asset, they generally include operating results, changes in the use of the asset, cash flows, and other indicators of value. Management then determines whether the remaining useful life continues to be appropriate, or whether there has been an impairment of long-lived assets based primarily upon whether expected future undiscounted cash flows are sufficient to support the assets’ recovery. If impairment exists, the Company adjusts the carrying value of the asset to fair value, generally determined by a discounted cash flow analysis.

For the years ended December 31, 2018, 2017 and 2016, the Company has not identified any impairment of its long-lived assets.

Business Combinations

The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the purchase method of accounting. Amounts paid for each acquisition are allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. The Company then allocates the purchase price in excess of net tangible assets acquired to identifiable intangible assets based on detailed valuations that use information and assumptions provided by management. Any excess purchase price over the fair value of the net tangible and intangible assets acquired and liabilities assumed is allocated to goodwill. If the fair value of the assets acquired exceeds the purchase price, the excess is recognized as a gain.

Significant management judgments and assumptions are required in determining the fair value of acquired assets and liabilities, particularly acquired intangible assets. The valuation of purchased intangible assets is based upon estimates of the future performance and cash flows from the acquired business. Each asset is measured at fair value from the perspective of a market participant.

If different assumptions are used, it could materially impact the purchase price allocation and adversely affect our results of operations, financial condition and cash flows.

Intangible Assets and Goodwill

Intangible assets that have finite lives are amortized over their estimated useful lives based on the pattern of consumption of the economic benefit or, if that pattern cannot be readily determined, on a straight-line basis and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, as discussed above.

Goodwill is not amortized, but is evaluated for impairment annually, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Conditions that could trigger a more frequent impairment assessment include, but are not limited to, a significant adverse change in certain agreements, significant underperformance relative to historical or projected future operating results, an economic downturn in customers’ industries, increased competition, a significant reduction in our stock price for a sustained period or a reduction of our market capitalization relative to net book value.

The Company has determined, based on its organizational structure, that it had one reporting unit as of December 31, 2018 and 2017. The Company evaluates impairment by comparing the estimated fair value of its reporting unit to its carrying value. The Company estimates fair value primarily utilizing the market approach, which calculates fair value based on the market values of comparable companies or comparable transactions.

The Company adopted ASU 2017-04 during the year ended December 31, 2018. The updated guidance eliminates Step 2 of the impairment test, which requires entities to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value, determined in Step 1. For the year ended December 31, 2018, the Company has not identified any impairment of its goodwill.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions, other events, and circumstances from non-owner sources. Accumulated other comprehensive loss is presented separately on the consolidated balance sheets and consists entirely of cumulative foreign translation adjustments as of December 31, 2018 and 2017.

Net Loss per Share

The Company calculates basic and diluted net loss per common share by dividing the net loss by the weighted-average number of common shares outstanding during the period. The Company has excluded (a) all unvested restricted shares that are subject to repurchase and (b) the Company’s other potentially dilutive shares, which include warrants to purchase common stock and outstanding common stock options and unvested restricted stock units, from the weighted-average number of common shares outstanding as their inclusion in the computation for all periods would be anti-dilutive due to net losses incurred.

The following outstanding common shares have been excluded from the computation of dilutive net loss per share as of December 31, 2018, 2017 and 2016:


	Year Ended December 31,
	2018		2017		2016
Options outstanding		2,738		4,127		4,291
Restricted stock units outstanding		3,034		2,050		1,668
Warrants		—		—		19

Income Taxes

The Company accounts for income taxes in accordance with the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. In addition, this method requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions recognized in the consolidated financial statements by prescribing a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Interest and penalties, if applicable, related to uncertain tax positions would be recognized as a component of income tax expense. The Company has no recorded liabilities for uncertain tax positions as of December 31, 2018 or 2017.

Stock-Based Compensation

At December 31, 2018, the Company had five stock-based compensation plans, which are more fully described in Note 7.

The Company values its shares of common stock in connection with the issuance of stock-based equity awards using the closing price of the Company’s shares of common stock on the NASDAQ Global Market on the date of the grant. Accounting guidance requires employee stock-based payments to be accounted for under the fair value method. Under this method, the Company is required to record compensation cost based on the estimated fair value for stock-based awards granted over the requisite service periods for the individual awards, which generally equals the vesting periods. The Company uses the straight-line amortization method for recognizing stock-based compensation expense associated with equity awards to employees.

For stock options issued under the Company’s stock-based compensation plans, the fair value of each option grant is estimated on the date of grant. For service-based options, the Company recognizes compensation expense on a straight-line basis over the requisite service period of the award.

The fair value of each option grant issued under the Company’s stock-based compensation plans was estimated using the Black-Scholes option-pricing model. The expected volatility of options granted has been determined using a weighted-average of the historical volatility measures of a peer group of companies that issued options with substantially similar terms as well as the historical volatility of the Company’s own common stock. The expected life of options has been determined utilizing the “simplified method”. The simplified method is based on the average of the vesting tranches and the contractual life of each grant. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid, and does not anticipate paying, cash dividends on its common stock; therefore, the expected dividend yield is assumed to be zero.

The weighted-average fair value of options granted during the years ended December 31, 2018, 2017 and 2016, was $4.11, $3.08 and $4.01 per share, respectively. The weighted-average assumptions utilized to determine such values are presented in the following table:


	Year Ended December 31,
	2018			2017			2016
Risk-free interest rate		2.88	%		2.08	%		1.75	%
Expected volatility		43	%		42	%		45	%
Expected life (in years)		6.2			6.1			6.2
Expected dividend yield		—			—			—

For restricted stock units issued under the Company’s stock-based compensation plans, the fair value of each grant is calculated based on the Company’s stock price on the date of grant. For performance-based awards with service-based vesting conditions, the Company recognizes compensation expense based upon a review of the Company’s expected achievement against the specified targets.

As of December 31, 2018, there was $16,967 of total unrecognized stock-based compensation expense related to stock-based awards that is expected to be recognized over a weighted-average period of 2.77 years. The following table summarizes stock-based compensation expense as included in the consolidated statement of operations for the years ended December 31, 2018, 2017 and 2016:


	Year Ended December 31,
	2018		2017		2016
Cost of subscription and support revenue	$	481	$	439	$	324
Cost of professional services and other revenue		242		251		217
Research and development		1,281		1,563		1,275
Sales and marketing		2,377		2,750		2,320
General and administrative		2,268		2,240		1,876

	$	6,649	$	7,243	$	6,012

Upon the adoption of ASU 2016-09 on January 1, 2017, we have elected to recognize prospectively gross stock-based compensation expense with actual forfeitures recognized as they occur. Prior to the adoption of ASU 2016-09, we estimated forfeitures at the time of grant and revised those estimates in subsequent periods if actual forfeitures differed from estimates.

For the years ended December 31, 2018, 2017 and 2016, stock-based compensation expense for stock options granted to non-employees in the accompanying consolidated statements of operations was not material.

See Note 7 for a summary of the stock option and restricted stock activity under the Company’s stock-based compensation plans for the year ended December 31, 2018.

Advertising Costs

Advertising costs are charged to operations as incurred. The Company incurred advertising costs of $2,657, $2,485 and $2,137 for the years ended December 31, 2018, 2017 and 2016, respectively.

Recent Accounting Pronouncements and Standards

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), Amendments to the FASB Accounting Standards Codification, which replaces the existing guidance for leases. ASU 2016-02 requires the identification of arrangements that should be accounted for as leases by lessees. In general, lease arrangements exceeding a twelve month term must now be recognized as assets and liabilities on the balance sheet of the lessee. Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. The balance sheet amount recorded for existing leases at the date of adoption of ASU 2016-02 must be calculated using the applicable incremental borrowing rate at the date of adoption. This guidance is effective for annual and interim periods beginning after December 15, 2018. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements, which provides an additional, optional transition method with which to adopt the new leases standard. This additional transition method allows for a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, rather than in the earliest period presented in the financial statements, as originally required by ASU 2016-02. The Company will to adopt the standard using the additional transition method introduced by ASU 2018-11. The Company completed its scoping assessment and determined that less than 15 leases will be impacted by the new standard. While the Company is still in the process of determining the effect that the new standard will have on its consolidated financial statements and related disclosures, the Company will be recognizing a significant amount of additional assets and corresponding liabilities on its consolidated balance sheet, as a result of its existing operating lease portfolio.

Recently Adopted Accounting Standards

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The standard addresses eight specific cash flow issues with the objective of reducing diversity in practice. ASU 2016-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The amendment requires the use of the retrospective transaction approach for adoption. The adoption of ASU 2016-15 did not have any effect on the Company’s consolidated financial statements or disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires an entity to reconcile and explain the period-over-period change in total cash, cash equivalents and restricted cash within its statement of cash flows. ASU 2016-18 is effective for annual and interim periods beginning after December 15, 2017. A reporting entity must apply the amendments in ASU 2016-18 using a full retrospective approach. The adoption of ASU 2016-18 did not have a material effect on the Company’s consolidated financial statements or disclosures.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendment changes the definition of a business to assist entities in evaluating when a set of transferred assets and activities constitutes a business. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. The adoption of ASU 2017-01 did not have a material effect on the Company’s consolidated financial statements or disclosures.

In May 2017 the FASB issued ASU 2017-09, Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU 2017-09 is effective for financial statements issued for annual reporting periods beginning after December 15, 2017 and interim periods within those years. The adoption of ASU 2017-09 did not have a material effect on the Company’s consolidated financial statements and related disclosures.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was enacted in the United States. The Act reduces the U.S. federal corporate tax rate from 34% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. In December 2017, the Securities and Exchange Commission (“SEC”) issued guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) directing taxpayers to consider the impact of the U.S. legislation as “provisional” when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. As of December 31, 2018, the Company had completed its accounting for all of the tax effects of the enactment of the Act, including the effects on its existing deferred tax balances and the one-time transition tax. The Company has not recognized any material adjustment to the provisional tax expense estimate previously recorded related to the Act. Refer to Note 9, Income Taxes, for additional information regarding this new tax legislation.

The Company has taken into consideration the other impacts of the Act that became effective in 2018, including the provisions related to Global Intangible Low Taxed Income (“GILTI”), Foreign Derived Intangible Income, Base Erosion Anti-Abuse Tax, as well as other provisions which would limit the deductibility of future expenses. Interpretive guidance on the accounting for GILTI states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. For the year ended December 31, 2018, the Company made the accounting policy election to recognize GILTI as a period expense.

Revenue from Contracts with Customers

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

3. Revenue from Contracts with Customers

The Company primarily derives revenue from the sale of its online video platform, which enables its customers to publish and distribute video to Internet-connected devices quickly, easily and in a cost-effective and high-quality manner. Revenue is derived from three primary sources: (1) the subscription to its technology and related support; (2) hosting, bandwidth and encoding services; and (3) professional services, which include initiation, set-up and customization services.

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which modifies how all entities recognize revenue, and consolidates revenue recognition guidance into one ASC Topic (ASC Topic 606, Revenue from Contracts with Customers). The Company adopted ASC 606 on January 1, 2018 and applied the modified retrospective method of adoption with a cumulative catch-up adjustment to the opening balance of retained earnings at January 1, 2018. Under this method, the Company applied the revised guidance for the year of adoption and applied ASC Topic 605, Revenue Recognition (“ASC 605”), in the prior years. As a result, the Company applied ASC 606 only to contracts that were not yet completed as of January 1, 2018. The Company recognized a cumulative catch-up adjustment to the opening balance of accumulated deficit at the effective date for contracts that still require performance by the entity at the date of adoption. ASC 606 outlines a comprehensive five-step revenue recognition model based on the principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Identify the contract with a customer

Identify the performance obligations in the contract

Determine the transaction price

Allocate the transaction price to performance obligations in the contract

Recognize revenue when or as the Company satisfies a performance obligation

The Company satisfies performance obligations as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised service to a customer.

Disaggregation of Revenue

The Company classifies its customers by including them in either premium or volume offerings. For premium offerings, the Company organizes its go-to-market approach by focusing its sales and marketing teams on selling primarily to (i) media companies, who generally want to distribute video content to a broad audience and (ii) enterprises and organizations, who generally use video for marketing or enterprise communication purposes.

The following table summarizes revenue from contracts with customers by business unit for the years ended December 31, 2018, 2017 and 2016.


	Year Ended December 31,
	2018		2017		2016
Revenue by Business Unit
Media	$	88,748	$	85,562	$	84,380
Enterprise		71,537		64,742		58,460
Volume		4,548		5,609		7,426

Total		164,833		155,913		150,266

Subscription and Support

The Company’s subscription arrangements provide customers the right to access its hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement. Contracts for premium customers generally have a term of one year and are non-cancellable. These contracts generally provide the customer with a maximum annual level of entitlement, and provide the rate at which the customer must pay for actual usage above the annual entitlement allowance. These subscription arrangements are considered stand ready obligations that are providing a series of distinct services that are substantially the same and are transferred with the same pattern to the customer. As such, these subscription arrangements are treated as a single performance obligation and the related fees are recognized as revenue ratably over the term of the underlying arrangement.

Under ASC 605, if usage exceeded the annual allowance level for a particular customer arrangement, the associated revenue was recognized in the period that the additional usage occurred. Under ASC 606, when the transaction price includes a variable amount of consideration, an entity is required to estimate the consideration that is expected to be received for a particular customer arrangement. The Company evaluates variable consideration for usage-based fees at contract inception and re-evaluates quarterly over the course of the contract. Specifically, the Company estimates the revenue pertaining to a customer’s usage that is expected to exceed the annual entitlement allowance and allocates such revenue to the distinct service within the related contract that gives rise to the variable payment. Estimates of variable consideration include analyzing customer usage against the applicable entitlement limit at the end of each reporting period and estimating the amount and timing of additional amounts to be invoiced in connection with projected usage. Estimates of variable consideration relating to customer usage do not include amounts for which it is probable that a significant reversal will occur. Determining the amount of variable consideration to recognize as revenue involves significant judgment on the part of management and it is possible that actual revenue will deviate from estimates over the course of a customer’s committed contract term.

Contracts with customers that are month-to-month arrangements (volume customers) have a maximum monthly level of usage and provide the rate at which the customer must pay for actual usage above the monthly allowable usage. The monthly volume subscription and support and usage fees are recognized as revenue during the related period of performance. Contracts with customers that are invoiced on a pay-as-you-go basis, where there is no monthly or annual commitment for usage, provide the rate at which the customer must pay for actual usage for a particular period. Fees that are invoiced on a pay-as-you-go basis are recognized as revenue during the period of performance.

Professional Services and Other Revenue

Professional services and other revenue consist of services such as implementation, software customizations and project management for customers who subscribe to our premium editions. These arrangements are priced either on a fixed fee basis with a portion due upon contract signing and the remainder due when the related services have been completed, or on a time and materials basis. Professional services and other revenue sold on a stand-alone basis are recognized as the services are performed, subject to any refund or other obligation.

Contracts with Multiple Performance Obligations

The Company periodically enters into multiple-element service arrangements that include platform subscription fees, support fees, and, in certain cases, other professional services. These contracts include multiple promises that the Company evaluates to determine if the promises are separate performance obligations. Performance obligations are identified based on services to be transferred to a customer that are both capable of being distinct and are distinct within the context of the contract. Once the Company determines the performance obligations, the Company determines the transaction price, which includes estimating the amount of variable consideration to be included in the transaction price, if any. The Company then allocates the transaction price to each performance obligation in the contract based on a relative stand-alone selling price method. The transaction price post allocation is recognized as revenue as the related performance obligation is satisfied.

Costs to Obtain a Contract

Commissions are paid to internal sales representatives as compensation for obtaining contracts. Under the new guidance, the Company capitalizes commissions that are incremental, as a result of costs incurred to obtain a customer contract, if those costs are not within the scope of another topic within the accounting literature and meet the specified criteria. Assets recognized for costs to obtain a contract are amortized over the period of performance for the underlying customer contracts. The commission expense on contracts with new customers was previously recorded over the respective contract term. Under the new guidance, the commission expense on contracts with new customers will be recorded over the average life of a customer given the commission amount associated with sales to new customers is not commensurate with the commission amount associated with the contract renewal for those same customers. The commission amount associated with the renewal of a contract in addition to any commission amount related to incremental sales was previously recorded as expense in the quarter the commission was earned; however, under ASC 606 these commission amounts are recorded as expense over the term of the renewed contract. These assets are periodically assessed for impairment.

Financial Statement Impact of Adoption ASC 606

The cumulative effect of applying the new guidance to all contracts with customers that were not completed as of January 1, 2018 was recorded as an adjustment to accumulated deficit as of the adoption date. As a result of applying the modified retrospective method to adopt the new revenue guidance, the following adjustments were made on the condensed consolidated balance sheet as of January 1, 2018.

Subscription and Support

Under ASC 606, the Company estimates the variable consideration to be received and recognizes those amounts, subject to constraint, as the Company satisfies its performance obligation. In conjunction with the January 1, 2018 adoption of ASC 606, the Company reduced accumulated deficit by $1,243 reflecting the recognition of revenue primarily relating to variable consideration, for contracts that still require performance by the entity at the date of adoption.

Costs to Obtain a Contract

Under the new guidance, the commission expense on contracts with new customers will be recorded over the average life of a customer given the commission amount associated with sales to new customers is not commensurate with the commission amount associated with the contract renewal for those same customers. The commission amount associated with the renewal of a contract in addition to any related incremental sale is recorded as expense over the term of the renewed contract. The net impact of these changes resulted in a $4,362 reduction to accumulated deficit for contracts that still require performance by the Company at the date of adoption.

Income Taxes

The adoption of ASC 606 primarily resulted in an acceleration of revenue and the reduction of expense as of December 31, 2017, which in turn generated additional deferred tax liabilities. As the Company fully reserves its net deferred tax assets in the jurisdictions impacted by the adoption of ASC 606, this impact was offset by a corresponding reduction to the valuation allowance.

Impact of New Revenue Guidance on Financial Statement Line Items

The following tables compare the reported condensed consolidated balance sheet, statement of operations and cash flows, as of and for the year ended December 31, 2018, to the pro-forma amounts had the previous guidance been in effect.

Total reported assets were $7,631 greater than the pro-forma balance sheet, which assumes the previous guidance remained in effect as of December 31, 2018. This was largely due to impacts of variable consideration and costs to obtain a contract.

Total reported liabilities were $1,424 greater than the pro-forma balance sheet, which assumes the previous guidance remained in effect as of December 31, 2018. This was largely due to the impact of variable consideration.

The following summarizes the significant changes on the Company’s condensed consolidated statement of operations for the year ended December 31, 2018 as a result of the adoption of ASC 606 on January 1, 2018 compared to if the Company had continued to recognize revenues under ASC 605.

The primary difference in subscription and support revenue relates to the impacts of applying the variable consideration guidance under ASC 606. Under the previous guidance, subscription and support revenue would have been approximately $175 higher, for the year ended December 31, 2018 as revenue for usage based fees, for contracts with annual entitlement allowances, was recognized in the month of such usage. Under ASC 606, usage based fees, for contracts with annual entitlement allowances, are recognized as revenue over the term of the underlying arrangement.

Sales and marketing expense, under the previous guidance, would have increased by approximately $777 for the year ended December 31, 2018. Sales and marketing expense would have increased by $777 for the year ended December 31, 2018, due to a portion of the commission payments being recorded immediately to expense at the time a liability was recorded. In addition, certain commission amounts that were amortized to expense over the underlying term of the arrangement are now amortized over the average customer life under ASC 606.

The net impact of accounting for revenue under the new guidance decreased net loss per share by $0.02 per basic and diluted share for the year ended December 31, 2018.

The adoption of ASC 606 had no impact on the Company’s cash flows from operations. The aforementioned impacts resulted in offsetting shifts in cash flows between net loss and various working capital balances.

The following summarizes the opening and closing balances of receivables, contract assets and contract liabilities from contracts with customers.


	Accounts Receivable, net		Contract Assets (current)		Deferred Revenue (current)		Deferred Revenue (non-current)		Total Deferred Revenue

Balance at December 31, 2018		23,264		1,640		39,846		146		39,992

Revenue recognized during the year ended December 31, 2018 from amounts included in deferred revenue at the beginning of the period was approximately $40.5 million. During the year ended December 31, 2018, the Company did not recognize revenue from performance obligations satisfied or partially satisfied in previous periods.

The assets recognized for costs to obtain a contract were $5.9 million and $5.4 million as of December 31, 2018 and January 1, 2018, respectively. Amortization expense recognized during the year ended December 31, 2018 related to costs to obtain a contract was $7.2 million.

Transaction Price Allocated to Future Performance Obligations

ASC 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as December 31, 2018. ASC 606 provides certain practical expedients that limit the requirement to disclose the aggregate amount of transaction price allocated to unsatisfied performance obligations.

Subscription and Support Revenue

As of December 31, 2018, the total aggregate transaction price allocated to the unsatisfied performance obligations for subscription and support contracts was approximately $109.4 million, of which approximately $90.7 million is expected to be recognized over the next 12 months. The Company expects to recognize substantially all of the remaining unsatisfied performance obligations by the end of 2020. The Company applied the practical expedient to not disclose the amount of transaction price allocated to unsatisfied performance obligations for variable consideration that the Company is able to allocate to one or more of the performance obligations in its contracts.

Professional Services

The Company applied the practical expedient to not disclose the amount of transaction price allocated to unsatisfied performance obligations when the performance obligation is part of a contract that has an original expected duration of one year or less. The Company does not have material future obligations associated with professional services that extend beyond one year.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

5. Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as an exit price, representing the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants based on the highest and best use of the asset or liability. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company uses valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

•

Level 1: Observable inputs, such as quoted prices for identical assets or liabilities in active markets;

•

Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly, such as quoted prices for similar assets or liabilities, or market-corroborated inputs; and

•

Level 3: Unobservable inputs for which there is little or no market data which require the reporting entity to develop its own assumptions about how market participants would price the assets or liabilities.

The valuation techniques that may be used to measure fair value are as follows:

A. Market approach — Uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

B. Income approach — Uses valuation techniques to convert future amounts to a single present amount based on current market expectations about those future amounts, including present value techniques, option-pricing models, and excess earnings method.

C. Cost approach — Based on the amount that currently would be required to replace the service capacity of an asset (replacement cost).

The following tables set forth the Company’s financial instruments carried at fair value using the lowest level of input as of December 31, 2018 and 2017:


	December 31, 2018
	Quoted Prices in Active Markets for Identical Items (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Assets:
Money market funds	$	8,299	$	—	$	—	$	8,299

Total assets	$	8,299	$	—	$	—	$	8,299

Total assets	$	8,160	$	—	$	—	$	8,160

Realized gains and losses from sales of the Company’s investments are included in “Other income (expense), net”.

The Company measures eligible assets and liabilities at fair value, with changes in value recognized in earnings. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities, and did not elect the fair value option for any financial assets and liabilities transacted in the years ended December 31, 2018 or 2017.

The Company’s primary office lease has the option to renew the lease for two successive periods of five years each. In connection with the office lease, the Company entered into a letter of credit in the amount of $2.4 million.

Certain of the Company’s operating leases include escalating payment amounts and lease incentives. The Company is recognizing the related rent expense on a straight-line basis over the term of the lease. The lease incentives are considered an inseparable part of the lease agreement, and are recognized as a reduction of rent expense on a straight-line basis over the term of the lease. As of December 31, 2018 and 2017, the Company had deferred rent and rent incentives of $1,264 and $1,464, respectively, of which $876 and $1,102, respectively, is classified as a long-term liability in the accompanying consolidated balance sheets. Rent expense for the years ended December 31, 2018, 2017 and 2016 was $7,857, $6,608 and $6,334, respectively. Income from sublease rental activity amounted to $92, $285 and $219, respectively, for the years ended December 31, 2018, 2017 and 2016. The Company’s existing sublease agreement expired in June 2018, and as of December 31, 2018, the Company was not party to any sublease agreements.

Capital Lease Commitments

The Company leases certain computer equipment and support under non-cancelable capital leases. The lease arrangements expire at various dates through April 2020. Future minimum rental commitments under capital leases at December 31, 2018 are as follows:

In addition to the operating lease and capital lease commitments discussed above, as of December 31, 2018, the Company had non-cancelable commitments of $17,415 and $3,000 payable in 2019 and 2020, respectively, primarily for content delivery network services, hosting and other support services.

Legal Matters

On May 22, 2017, a lawsuit was filed against Brightcove and two individuals by Ooyala, Inc. (“Ooyala”) and Ooyala Mexico S. de R.L. de C.V. (“Ooyala Mexico”). The lawsuit, which was filed in the United States District Court for the District of Massachusetts, concerned allegations that the two individuals, who were former employees of Ooyala Mexico, misappropriated customer information and other trade secrets and used that information in working for Brightcove. The complaint was amended on June 1, 2017 to remove claims against the two former employees of Ooyala Mexico. The remaining claims against Brightcove were for violation of the Defend Trade Secrets Act of 2016 (18 U.S.C. §1836), violation of the Massachusetts trade secret statute (M.G.L. c. 93, §42), violation of Massachusetts Chapter 93A (M.G.L. c. 93A, §11), and tortious interference with advantageous business relationships. Ooyala and Ooyala Mexico also filed a motion for preliminary injunction (amended at the same time the complaint was amended), seeking to enjoin Brightcove from using any of the allegedly misappropriated information or communicating with customers whose information was taken, and seeking the return of any information that was allegedly taken. On June 16, 2017, Brightcove filed an opposition to the motion for preliminary injunction, and also moved to dismiss the lawsuit. The motion to dismiss was denied on September 6, 2017. The court issued a preliminary injunction on July 10, 2018. The injunction required Brightcove to delete any Ooyala confidential information obtained from the former Ooyala employees and prohibited Brightcove from using such information to pursue business with twenty-two specified Latin American prospective customers. On October 19, 2018, the parties settled the matter for an immaterial amount, and the case was dismissed on October 24, 2018.

On October 26, 2017, Realtime Adaptive Streaming LLC filed a complaint against Brightcove and its subsidiary Brightcove Holdings, Inc. in the United States District Court for the District of Delaware. The complaint alleged that Brightcove infringed five patents related to file compression technology. The complaint sought monetary damages and injunctive relief. On December 1, 2017, Realtime filed an amended complaint, adding two additional patents to its claims. Brightcove filed a motion to dismiss on January 26, 2018. The plaintiff filed an opposition to the motion to dismiss on February 9, 2018 and Brightcove filed a reply on February 16, 2018. A ruling on the motion to dismiss was not issued by the court. On July 31, 2018, Brightcove filed a Motion to Transfer Venue, which motion was opposed by the plaintiff. On October 18, 2018, Brightcove, via its insurer, entered into a Patent License Agreement which provides Brightcove a license to the patents-in-suit (as well as additional patents and patent applications owned by Realtime) in exchange for a one-time payment, which is immaterial in amount. As a result of entering into the Patent License Agreement, the case was dismissed on October 31, 2018.

On January 30, 2019, Uniloc 2017 LLC filed a complaint against the Company and its subsidiary, Brightcove Holdings, Inc. in the United States District Court for the District of Delaware. The complaint alleges that Brightcove infringed four patents and seeks monetary damages and other relief. The Company cannot yet determine whether it is probable that a loss will be incurred in connection with this complaint, nor can the Company reasonably estimate the potential loss, if any.

The Company, from time to time, is party to litigation arising in the ordinary course of business. Management does not believe that the outcome of these claims will have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company based on the status of proceedings at this time.

Guarantees and Indemnification Obligations

The Company typically enters into indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses and costs incurred by the indemnified party, generally the Company’s customers, in connection with patent, copyright, trade secret, or other intellectual property or personal right infringement claims by third parties with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual after execution of the agreement. Based on when customers first subscribe for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited, however, more recently the Company has typically limited the maximum potential value of such potential future payments in relation to the value of the contract. Based on historical experience and information known as of December 31, 2018, the Company has not incurred any costs for the above guarantees and indemnities. The Company has received requests for indemnification from customers in connection with patent infringement suits brought against the customer by a third party. To date, the Company has not agreed that the requested indemnification is required by the Company’s contract with any such customer.

In certain circumstances, the Company warrants that its products and services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the licensed products and services to the customer for the warranty period of the product or service. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

Stockholders' Equity

7. Stockholders’ Equity

Common Stock

Common stockholders are entitled to one vote per share. Holders of common stock are entitled to receive dividends, when and if declared by the Board.

Treasury Stock

The Company has recorded 135,000 shares as treasury stock as of December 31, 2018 and 2017.

Equity Incentive Plans

At December 31, 2018, the Company had five stock-based compensation plans, the Amended and Restated 2004 Stock Option and Incentive Plan (the 2004 Plan), the 2012 Stock Incentive Plan (the 2012 Plan), the Brightcove Inc. 2012 RSU Inducement Plan (the RSU Plan), the Brightcove Inc. 2014 Stock Option Inducement Plan (the 2014 Stock Inducement Plan), and the 2018 Inducement Plan (the 2018 plan). The 2004 Plan and the 2012 Plan provided for the issuance of incentive and non-qualified stock options, restricted stock, and other equity awards to the Company’s employees, officers, directors, consultants and advisors. In conjunction with the effectiveness of the 2012 Plan, the Board voted that no further stock options or other equity-based awards may be granted under the 2004 Plan.

The number of shares reserved and available for issuance under the 2012 Plan automatically increases each January 1, beginning in 2013, by 4% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31 or such lesser number of shares as determined by the Company’s compensation committee subject to an overall overhang limit of 30%. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization.

In 2012, the Company adopted the RSU Plan in connection with the acquisition of Zencoder. The restricted stock units were settled in shares of the Company’s common stock upon vesting.

In 2014, the Company adopted the 2014 Stock Inducement Plan in connection with the Unicorn asset purchase agreement.

Effective April 11, 2018, the Company adopted the 2018 Plan. The 2018 Plan provides for the issuance of stock options and restricted stock units to the Company’s Chief Executive Officer (“CEO”).

During 2018, the Company granted an aggregate of 1,169,000 restricted stock units to certain key executives, which contain both performance-based and service-based vesting conditions. The Company measures compensation expense for these performance-based awards based upon a review of the Company’s expected achievement against specified financial performance targets. Compensation cost is recognized on a ratable basis over the requisite service period for each series of grants to the extent management has deemed that such awards are probable of vesting based upon the expected achievement against the specified targets. On a periodic basis, management reviews the Company’s expected performance and adjusts the compensation cost, if needed, at such time.

At December 31, 2018, 2,105,806 shares were available for issuance under all stock-based compensation plans.

The following is a summary of the stock option activity for all stock option plans during the year ended December 31, 2018:

The aggregate intrinsic value for options exercised during the years ended December 31, 2017 and 2016 was $1,243 and $5,159, respectively.

The Company has entered into restricted stock unit (RSU) agreements with certain of its employees pursuant to the 2012 Plan and the RSU Plan. Vesting occurs periodically at specified time intervals, ranging from three months to four years, and in specified percentages. Upon vesting, the holder will receive one share of the Company’s common stock for each unit vested.

The following table summarizes the RSU activity during the year ended December 31, 2018:

The Company is required to compute income tax expense in each jurisdiction in which it operates. This process requires the Company to project its current tax liability and estimate its deferred tax assets and liabilities, including net operating loss (NOL) and tax credit carry-forwards. In assessing the ability to realize the net deferred tax assets, management considers whether it is more likely than not that some portion or all of the net deferred tax assets will not be realized.

The Company has provided a valuation allowance against its remaining U.S. net deferred tax assets as of December 31, 2018 and 2017, as based upon the level of historical U.S. losses and future projections over the period in which the net deferred tax assets are deductible, at this time, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences. The increase in the valuation allowance from 2017 to 2018 of $2.7 million principally relates to the current year taxable loss. The Company maintains net deferred tax liabilities for temporary differences related to its foreign subsidiaries.

As of December 31, 2018, the Company had federal and state net operating losses of approximately $161.8 million and $76.8 million, respectively, which are available to offset future taxable income, if any, through 2038. The Company had federal and state net operating losses of approximately $13.8 million and $0.7 million, respectively, which are available to offset future taxable income, if any, indefinitely. The Company also had federal and state research and development tax credits of $6.9 million and $4.4 million, respectively, which expire in various amounts through 2038. The net operating loss and tax credit amounts are subject to annual limitations under Section 382 change of ownership rules under the U.S. Internal Revenue Code of 1986, as amended. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. The Company has not conducted an assessment to determine whether there may have been a Section 382 ownership change from June 30, 2014, the date of the most recent completed study, through December 31, 2018. If a change in ownership were to have occurred during that period, and resulted in the restriction of net operating loss and tax credit carryforwards, the reduction in the related deferred tax asset would be offset with a corresponding reduction in the valuation allowance.

On January 1, 2009, the Company adopted the provision for uncertain tax positions under ASC 740, Income Taxes. The adoption did not have an impact on the Company’s retained earnings balance. At December 31, 2018 and 2017, the Company had no recorded liabilities for uncertain tax positions.

At December 31, 2018 and 2017, the Company had no accrued interest or penalties related to uncertain tax positions.

The Company files income tax returns in the U.S. federal tax jurisdiction, various state and various foreign jurisdictions. The Company is currently open to examination under the statute of limitations by the Internal Revenue Service and state jurisdictions for the tax years ended 2015 through 2018. Since the Company is in a U.S. loss carryforward position, carryforward tax attributes generated in prior years may still be adjusted upon future examination if they have or will be used in a future period. Additionally, certain non-U.S. jurisdictions are no longer subject for income tax examinations by authorities for tax years before 2013.

As of December 31, 2018, the Company had completed its accounting for all of the tax effects of the enactment of the Act, including the effects on its existing deferred tax balances and the one-time transition tax. The Company had not recognized any material adjustment to the provisional tax expense estimate previously recorded related to the Act.

No additional U.S. income taxes or foreign withholding taxes have been provided for any additional outside basis differences inherent in the Company’s foreign entities as these amounts continue to be indefinitely reinvested in foreign operations based on management’s current intentions. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities (i.e., basis difference in excess of that subject to the one-time transition tax) is not practicable.

Debt Disclosure [Abstract]
Debt	9. Debt On December 14, 2018, we entered into an amended and restated loan and security agreement with a lender (the “Loan Agreement”) providing for up to a $30.0 million asset based line of credit (the “Line of Credit”). Under the Line of Credit, we can borrow up to $30.0 million. Borrowings under the Line of Credit are secured by substantially all of our assets, excluding our intellectual property. Outstanding amounts under the Line of Credit accrue interest at a rate as follows; (i) for prime rate advances, the greater of (A) the prime rate and (B) 4%, and (ii) for LIBOR advances, the greater of (A) the LIBOR rate plus 225 basis points (the “LIBOR rate margin”) and (B) 4%. Under the Loan Agreement, we must comply with certain financial covenants, including maintaining a minimum asset coverage ratio. If the outstanding principal during any month is at least $15.0 million, the Company must also maintain a minimum net income threshold based on non-GAAP operating measures. Failure to comply with these covenants, or the occurrence of an event of default, could permit the Lenders under the Line of Credit to declare all amounts borrowed under the Line of Credit, together with accrued interest and fees, to be immediately due and payable. We were in compliance with all covenants under the Line of Credit as of December 31, 2018 and there were no borrowings outstanding.
