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, allowances for doubtful accounts, contingent liabilities, the expensing and capitalization of research and development costs for internal-use software, 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, stock-based compensation expense, and the recoverability of the Company’s net 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 and non-controlling interest. All significant intercompany balances and transactions have been eliminated in consolidation.

Non-controlling interest in 2012 represents the minority stockholders’ proportionate share (37%) of the Company’s majority-owned subsidiary, Brightcove KK, a Japanese joint venture, which was formed on July 18, 2008. The portion of net income attributable to non-controlling interest prior to the remaining acquisition in 2013 is presented as net income attributable to non-controlling interest in consolidated subsidiary in the consolidated statements of operations, and the portion of other comprehensive loss of this subsidiary is presented in the consolidated statements of stockholders’ equity and statements of comprehensive loss. See Note 8 for further discussion.

On January 8, 2013, the Company acquired the remaining 37% interest in Brightcove KK. The purchase price of the remaining interest of Brightcove KK was approximately $1.1 million and was funded by cash on hand. The Company owned a 63% interest in the Brightcove KK joint venture since its formation in 2008. Brightcove KK is now 100% owned by the Company. The purchase was accounted for as an equity transaction and, as such, the Company has continued to consolidate Brightcove KK for financial reporting purposes; however, commencing on January 8, 2013, the Company no longer records non-controlling interest in its consolidated financial statements.

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 there are no material recognized or unrecognized subsequent events, except as disclosed Note 14 and elsewhere within these notes to the consolidated financial statements.

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, 2015 or 2014.

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, 2015 and 2014 consist of the following:


	December 31, 2015
Description	Contracted Maturity		Amortized Cost		Fair Market Value		Balance Per Balance Sheet
Cash		Demand	$	18,057	$	18,057	$	18,057
Money market funds		Demand		9,580		9,580		9,580

Total cash and cash equivalents			$	27,637	$	27,637	$	27,637


	December 31, 2014
Description	Contracted Maturity		Amortized Cost		Fair Market Value		Balance Per Balance Sheet
Cash		Demand	$	13,342	$	13,342	$	13,342
Money market funds		Demand		9,574		9,574		9,574

Total cash and cash equivalents			$	22,916	$	22,916	$	22,916

Restricted Cash

At December 31, 2015 and 2014, restricted cash was $201 and was held in certificates of deposit as collateral for letters of credit related to the contractual provisions of the Company’s corporate credit cards and the contractual provisions with a customer.

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 and capital lease liabilities, approximated their fair values at December 31, 2015 and 2014, 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 Recognition

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.

The Company recognizes revenue when all of the following conditions are satisfied: (1) there is persuasive evidence of an arrangement; (2) the service has been provided to the customer; (3) the collection of fees is probable; and (4) the amount of fees to be paid by the customer is fixed or determinable.

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. Accordingly, the Company recognizes revenue in accordance with ASC 605, Revenue Recognition. 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 usage, and provide the rate at which the customer must pay for actual usage above the annual allowable usage. For these services, the Company recognizes the annual fee ratably as revenue each month. Should a customer’s usage of the Company’s services exceed the annual allowable level, revenue is recognized for such excess in the period of the usage. Contracts for volume customers are generally month-to-month arrangements, 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 period in which the related cash is collected.

Revenue recognition commences upon the later of when the application is placed in a production environment, or when all revenue recognition criteria have been met.

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.

Deferred revenue includes amounts billed to customers for which revenue has not been recognized, and primarily consists of the unearned portion of annual software subscription and support fees, and deferred professional service fees.

Revenue is presented net of any taxes collected from customers.

Multiple-Element Arrangements

The Company periodically enters into multiple-element service arrangements that include platform subscription fees, support fees, and, in certain cases, other professional services.

The Company assesses arrangements with multiple deliverables under ASU No. 2009-13, Revenue Recognition (Topic 605), Multiple-Deliverable Revenue Arrangements — a Consensus of the FASB Emerging Issues Task Force, which amended the previous multiple-element arrangements accounting guidance. Pursuant to ASU 2009-13, objective and reliable evidence of fair value of the undelivered elements is no longer required in order to account for deliverables in a multiple-element arrangement separately. Instead, arrangement consideration is allocated to deliverables based on their relative selling price. The new guidance also eliminates the use of the residual method.

In order to treat deliverables in a multiple-element arrangement as separate units of accounting, the deliverables must have stand-alone value upon delivery. If the deliverables have stand-alone value upon delivery, the Company accounts for each deliverable separately. Subscription services have stand-alone value as such services are often sold separately. In determining whether professional services have stand-alone value, the Company considers the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the subscription service start date, and the contractual dependence of the subscription service on the customer’s satisfaction with the professional services work. To date, the Company has concluded that all of the professional services included in multiple-element arrangements executed have stand-alone value.

When multiple deliverables included in an arrangement are separated into different units of accounting, the arrangement consideration is allocated to the identified separate units based on a relative selling price hierarchy. The Company determines the relative selling price for a deliverable based on its vendor-specific objective evidence of fair value (VSOE), if available, or its best estimate of selling price (BESP), if VSOE is not available. The Company has determined that third-party evidence of selling price (TPE) is not a practical alternative due to differences in its service offerings compared to other parties and the availability of relevant third-party pricing information. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.

The Company has not established VSOE for its offerings due to the lack of pricing consistency, the introduction of new services and other factors. Accordingly, the Company uses its BESP to determine the relative selling price. The Company determines BESP by considering its overall pricing objectives and market conditions. Significant pricing practices taken into consideration include the Company’s discounting practices, the size and volume of the Company’s transactions, the geographic area where services are sold, price lists, historical contractually stated prices and prior relationships and future subscription service sales with certain classes of customers.

The determination of BESP is made through consultation with and approval by the Company’s management, taking into consideration the go-to-market strategy. As the Company’s go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes in selling prices, including both VSOE and BESP. The Company analyzes the selling prices used in its allocation of arrangement consideration, at a minimum, on an annual basis. Selling prices are analyzed on a more frequent basis if a significant change in the Company’s business necessitates a more timely analysis or if the Company experiences significant variances in its selling prices.

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, 2015, 2014 and 2013:


	Balance at Beginning of Period		Provision		Write-offs			Balance at End of Period
Year ended December 31, 2015	$	181	$	408	$	(257	)	$	332
Year ended December 31, 2014		461		118		(398	)		181
Year ended December 31, 2013		338		449		(326	)		461

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 routinely assesses the creditworthiness of its customers. 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, 2015, 2014 and 2013, no individual customer accounted for more than 10% of total revenue.

As of December 31, 2015 and 2014, no individual customer accounted for more than 10% of net accounts receivable.

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, 2015, 2014 and 2013, the Company capitalized $1,488, $474 and $1,065, respectively, of internal-use software development costs. The Company recorded amortization expense associated with its capitalized internal-use software development costs of $469, $397 and $312 for the years ended December 31, 2015, 2014 and 2013, 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,
		2015		2014
Computer equipment	3	$	20,459	$	19,815
Software	3 - 6		10,766		9,245
Furniture and fixtures	5		1,942		1,827
Leasehold improvements	Shorter of lease term or the estimated useful life		1,059		929

			34,226		31,816
Less accumulated depreciation and amortization			25,537		21,444

		$	8,689	$	10,372

Depreciation and amortization expense, which includes amortization expense associated with capitalized internal-use software development costs, for the years ended December 31, 2015, 2014 and 2013 was $5,575, $5,387 and $4,148, respectively.

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

During the quarter ended December 31, 2015, the Company returned $1.2 million of equipment that was originally purchased in the quarter ended June 30, 2015, and received a refund from the vendor for the full amount. As such, the Company reversed $274 of depreciation expense in the quarter ended December 31, 2015 that was recorded in previous quarters. Refer to Note 10 for a discussion of the return of 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, 2015, 2014 and 2013, 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.

In assessing the recoverability of goodwill, the Company must make assumptions regarding the estimated future cash flows, and other factors, to determine the fair value of these assets. If these estimates or their related assumptions change in the future, the Company may be required to record impairment charges against these assets in the reporting period in which the impairment is determined. The Company has determined, based on its organizational structure, that it had one reporting unit as of December 31, 2015 and 2014.

For goodwill, the impairment evaluation includes a comparison of the carrying value of the reporting unit to the fair value of the reporting unit. If the reporting unit’s estimated fair value exceeds the reporting unit’s carrying value, no impairment of goodwill exists. If the fair value of the reporting unit does not exceed its carrying value, then further analysis would be required to determine the amount of the impairment, if any.

In accordance with ASU No. 2011-08, Intangibles — Goodwill and Other (Topic 350) Testing Goodwill for Impairment, the Company has the option to assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount to determine whether further impairment testing is necessary. Based on the results of the qualitative review of goodwill performed as of December 31, 2015 and 2014, the Company did not identify any indicators of impairment. As such, the two-phase process described above was not necessary.

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, 2015 and 2014.

Net Loss per Share

The Company calculates basic and diluted net loss per common share by dividing the net loss attributable to common stockholders 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 potentially dilutive common shares have been excluded from the computation of dilutive net loss per share as of December 31, 2015, 2014 and 2013, as their effect would have been antidilutive:


	Year Ended December 31,
	2015		2014		2013
	(in thousands)
Options outstanding		4,139		3,805		3,331
Restricted stock units outstanding		1,043		990		1,398
Warrants		28		28		28

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, 2015 or 2014.

Stock-Based Compensation

At December 31, 2015, the Company had four stock-based compensation plans, which are more fully described in Note 7.

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, and an estimated forfeiture rate is used when calculating stock-based compensation expense for the period. For service-based options, the Company recognizes compensation expense on a straight-line basis over the requisite service period of the award. 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.

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. Prior to 2015, as there was no public market for its common stock prior to February 17, 2012, the effective date of the Company’s IPO, and as the trading history of the Company’s common stock was limited through December 31, 2015, the Company determined the volatility for options granted based on an analysis of reported data for a peer group of companies that issued options with substantially similar terms. The expected volatility of options granted had been determined using a weighted average of the historical volatility measures of this peer group of companies. Beginning in 2015, as there was at least three years of trading history of the Company’s common stock, the expected volatility of options granted has been determined using a weighted-average of the historical volatility measures of this peer group of companies 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. In addition, based on an analysis of the historical actual forfeitures, the Company applied an estimated forfeiture rate of approximately 17%, 17% and 15% for the years ended December 31, 2015, 2014 and 2013, respectively, in determining the expense recorded in the accompanying consolidated statements of operations.

The weighted-average fair value of options granted during the years ended December 31, 2015, 2014 and 2013, was $3.10, $4.21 and $5.34 per share, respectively. The weighted-average assumptions utilized to determine such values are presented in the following table:


	Year Ended December 31,
	2015			2014			2013
Risk-free interest rate		1.96	%		2.16	%		1.80	%
Expected volatility		46	%		52	%		54	%
Expected life (in years)		6.2			6.2			6.2
Expected dividend yield		—			—			—

As of December 31, 2015, there was $11,937 of total unrecognized stock-based compensation expense related to stock based awards that is expected to be recognized over a weighted-average period of 2.91 years. The total unrecognized stock-based compensation expense will be adjusted for future changes in estimated forfeitures.

The Company accounts for transactions in which services are received from non-employees in exchange for equity instruments based on the fair value of such services received, or of the equity instruments issued, whichever is more reliably measured. The Company determines the total stock-based compensation expense related to non-employee awards using the Black-Scholes option-pricing model. Additionally, in accordance with ASC 505, Equity-Based Payments to Non-Employees, the Company accounts for awards to non-employees prospectively, such that the fair value of the awards is remeasured at each reporting date until the earlier of (a) the performance commitment date or (b) the date the services required under the arrangement have been completed.

For the years ended December 31, 2015, 2014 and 2013, stock-based compensation expense for stock options granted to non-employees in the accompanying consolidated statements of operations was not material.

For the years ended December 31, 2015, 2014 and 2013, total stock-based compensation expense was $6,014, $6,387 and $6,401, respectively.

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, 2015.

Advertising Costs

Advertising costs are charged to operations as incurred. The Company incurred advertising costs of $2,081, $3,515 and $3,215 for the years ended December 31, 2015, 2014 and 2013, respectively.

Recent Accounting Pronouncements

In May 2014, the FASB and the International Accounting Standards Board jointly issued ASU No. 2014-9, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards. The core principle of the guidance is 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 and services. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2017 and allows for either full retrospective or modified retrospective application, with early adoption not permitted. Accordingly, the standard is effective for the Company on January 1, 2018. The Company is currently evaluating the adoption method it will apply and the impact that this guidance will have on its financial statements and related disclosures. Early adoption is permitted, but not before the original public organization effective date (that is, annual periods beginning after December 15, 2016).

In August 2014, the FASB issued ASU No. 2014-15,Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires management to evaluate, at each annual or interim reporting period, whether there are conditions or events that exist that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016 and earlier application is permitted. The adoption of ASU 2014-15 is not expected to have a material effect on the Company’s consolidated financial statements or disclosures.

In February 2015, the FASB issued updated accounting guidance on consolidation requirements. This update changes the guidance with respect to the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. This guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on its financial statements.

In April 2015, the FASB issued ASU 2015-03, Interest — Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs, which provides that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of the related debt liability, rather than classifying the costs separately in the balance sheet as a deferred charge. The ASU aims to reduce complexity. This standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, with early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements or disclosures.

Business Combinations [Abstract]
Business Combinations	3. Business Combinations *Unicorn Media, Inc.* On January 31, 2014, the Company acquired substantially all of the assets of Unicorn Media, Inc. and certain of its subsidiaries, or Unicorn, a provider of cloud video ad insertion technology, for total consideration of approximately $39.7 million, which was funded by cash on hand of $9.1 million and the issuance of 2,850,547 shares of common stock (the Acquisition). This transaction was accounted for under the purchase method of accounting in accordance with ASC 805 — Business Combinations. Accordingly, the results of operations of Unicorn have been included in the Company’s consolidated financial statements since the date of acquisition. All of the assets acquired and liabilities assumed in the transaction have been recognized at their acquisition date fair values, which were finalized at December 31, 2014. The Acquisition did not result in the addition of any reportable segments. Pursuant to the asset purchase agreement, 1,285,715 shares were placed into an escrow account to settle certain claims for indemnification for breaches or inaccuracies in Unicorn’s representations and warranties, covenants and agreements. Prior to the expiration of the indemnity period, the Company posted claims against the escrow account related to liabilities discovered after the date of the acquisition and related matters. In December 2015, the Company entered into a settlement agreement with the Securityholders’ Representative, on behalf of the former stockholders of Unicorn Media, Inc., and received 135,000 shares in exchange for settling the escrow matters and releasing the counterparty from all future liabilities relating to the claims. The Company accounted for the settlement of shares as treasury stock and recorded a corresponding gain of $871 to other expense, net in the consolidated statement of operations.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

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, 2015 and 2014:


	December 31, 2015
	Quoted Prices in Active Markets for Identical Items (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Assets:

Restricted cash		—		201		—		201

Total assets	$	9,574	$	201	$	—	$	9,775

Realized gains and losses from sales of the Company’s investments are included in “Other 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, 2015 or 2014.

- Definition

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, 2015 and 2014, the Company had deferred rent and rent incentives of $1,653 and $1,548, respectively, of which $1,565 and $1,483, respectively, is classified as a long-term liability in the accompanying consolidated balance sheets. Rent expense for the years ended December 31, 2015, 2014 and 2013 was $6,831, $6,280 and $5,328, respectively. Income from sublease rental activity amounted to $185, $0 and $0, respectively, for the years ended December 31, 2015, 2014 and 2013.

Capital Lease Commitments

In connection with the acquisition of substantially all of the assets of Unicorn, the Company assumed various capital lease arrangements for certain computer equipment for a total obligation of $2,899 as of the closing of the acquisition. During 2015, the Company entered into additional capital lease arrangements for computer equipment and support for a total obligation of $1,294. Amortization expense relating to assets acquired under capital lease is included within depreciation expense. Amortization expense related to assets acquired under capital lease was $469, $408, and $0 for the years ended December 31, 2015, 2014 and 2013, respectively. The lease arrangements expire at various dates through September 2018. Future minimum rental commitments under capital leases at December 31, 2015 are as follows:


Year Ending December 31	Capital Lease Commitments
2016	$	895
2017		508
2018		231

	$	1,567

At December 31, 2015, total assets under capital leases were $3,607 and related accumulated amortization was $2,006.

In addition to the operating lease and capital lease commitments discussed above, as of December 31, 2015, the Company had non-cancelable commitments of $8,649 payable in 2016 and $8,000 payable in 2017 primarily for content delivery network and storage services.

Legal Matters

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.

On August 27, 2012, a complaint was filed by Blue Spike, LLC naming the Company in a patent infringement case (Blue Spike, LLC v. Audible Magic Corporation, et al., United States District Court for the Eastern District of Texas). The complaint alleges that the Company has infringed U.S. Patent No. 7,346,472 with a listed issue date of March 18, 2008, entitled “Method and Device for Monitoring and Analyzing Signals,” U.S. Patent No. 7,660,700 with a listed issue date of February 9, 2010, entitled “Method and Device for Monitoring and Analyzing Signals,” U.S. Patent No. 7,949,494 with a listed issue date of May 24, 2011, entitled “Method and Device for Monitoring and Analyzing Signals” and U.S. Patent No. 8,214,175 with a listed issue date of July 3, 2012, entitled “Method and Device for Monitoring and Analyzing Signals.” The complaint seeks an injunction enjoining infringement, damages and pre- and post-judgment costs and interest. The Company answered and filed counterclaims against Blue Spike on December 3, 2012. The Company amended its answer and counterclaims on July 15, 2013. This complaint is subject to indemnification by one of the Company’s vendors. 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.

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 claim 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, 2015, 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.

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, 2015 with a cost of $871. See Note 3 for additional information.

Equity Incentive Plans

At December 31, 2015, the Company had four 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), and the Brightcove Inc. 2014 Stock Option Inducement Plan (the 2014 Stock Inducement Plan).

The 2004 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, up to an aggregate of 7,397,843 shares of the Company’s common stock. The Company also established a UK Sub-Plan of the 2004 Plan under which the Company was permitted to make grants of options to employees subject to tax in the United Kingdom. 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.

In 2012, the Board and stockholders adopted the 2012 Plan, which became effective on February 16, 2012. The 2012 Plan provides for the issuance of incentive and non-qualified stock options, restricted stock and other stock-based awards to the Company’s officers, employees, non-employee directors and certain other key persons of the Company as are selected by the Board or the compensation committee thereof. In connection with the approval of the 2012 Plan, the Company reserved 1,700,000 shares of common stock for issuance under the 2012 Plan, and 124,703 shares were transferred from 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 and made awards of restricted stock units pursuant to the RSU Plan to 15 new employees in connection with the acquisition of Zencoder. The awards of restricted stock units cover an aggregate of 77,100 shares of the Company’s common stock and were made as a material inducement to the employees entering into employment with the Company in connection with the acquisition of Zencoder. The restricted stock units will be settled in shares of the Company’s common stock upon vesting.

In 2014, the Company adopted the 2014 Stock Inducement Plan and made awards of options pursuant to the 2014 Stock Inducement Plan to 61 new employees in connection with the asset purchase agreement. The awards of options cover an aggregate of 578,350 shares of the Company’s common stock in the form of options to purchase shares of the Company’s common stock as an inducement to the employees entering into employment with the Company in connection with the asset purchase agreement.

At December 31, 2015, 883,129 shares were available for issuance under all stock-based compensation plans.

The following is a summary of the stock option activity for all stock options plans during the year ended December 31, 2015:


	Shares			Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value ⁽²⁾
Outstanding at December 31, 2014		4,077,074		$	7.02
Granted		1,299,249		$	6.60
Exercised		(58,449	)	$	2.21			$	281

Vested and expected to vest at December 31, 2015 ⁽¹⁾		4,003,461		$	6.58		6.64	$	5,039

(1)	This represents the number of vested options as of December 31, 2015 plus the number of unvested options expected to vest as of December 31, 2015, based on the unvested options outstanding at December 31, 2015 and adjusted for the estimated forfeiture rate.

(2)	The aggregate intrinsic value was calculated based on the positive difference between the estimated fair value of the Company’s common stock on December 31, 2015 of $6.20 per share, or the date of exercise, as appropriate, and the exercise price of the underlying options.

The aggregate intrinsic value for options exercised during the years ended December 31, 2014 and 2013 was $1,499 and $7,104, 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, 2015:


	Shares			Weighted Average Grant Date Fair Value

Warrants

In September 2006, the Company issued fully vested warrants to purchase an aggregate of 46,713 shares of Series B Preferred Stock, at a purchase price of $3.21 per share, to two lenders in connection with a line of credit agreement. The warrants are exercisable at any time up until the expiration date of August 31, 2016. The fair value of the warrants was recorded as a discount on the related debt, and was amortized to interest expense over the life of the debt. The debt was fully repaid in March 2007. The warrant liability was reported at fair value until completion of the Company’s IPO in February 2012, whereupon the warrants automatically converted into warrants to purchase shares of the Company’s common stock. At the time of conversion of the warrants in connection with the Company’s IPO, the fair value of the warrants was $395, which was reclassified as a component of additional paid-in capital.

During 2012, 18,685 shares exercisable under the warrants were exercised pursuant to a net exercise provision, which resulted in the issuance of 15,781 common shares. There have been no additional exercises through December 31, 2015. The warrants expire in August 2016.

Noncontrolling Interest [Abstract]

Non-controlling Interest

8. Non-controlling Interest

On May 30, 2008, the Company formed Brightcove KK, a wholly owned subsidiary of Brightcove Inc. On July 18, 2008, the Company entered into a joint venture agreement with J-Stream Inc. (J-Stream), Dentsu, Inc. (Dentsu), Cyber Communications, Inc. and Transcosmos Investments & Business Development, Inc. (collectively, the minority stockholders). The minority stockholders invested cash of approximately $4.8 million in Brightcove KK such that their cumulative ownership interest in the entity was 37%, while the Company retained a 63% ownership interest in the entity. The Company determined that it had a controlling interest and was the primary beneficiary of the entity. As such, the Company consolidated Brightcove KK for financial reporting purposes, and a non-controlling interest was recorded for the third parties’ interest in the net assets and operations of Brightcove KK to the extent of the non-controlling partners’ individual investments.

On January 8, 2013, the Company acquired the remaining 37% interest in Brightcove KK and, as a result, Brightcove KK is now 100% owned by the Company. The purchase price of the remaining equity interest was approximately $1.1 million and was funded by cash on hand. The Company continues to consolidate Brightcove KK for financial reporting purposes, however, commencing on January 8, 2013, the Company no longer records a non-controlling interest in the consolidated financial statements. The purchase was accounted for as an equity transaction in accordance with ASC 810, Consolidation. Accordingly, the non-controlling interest in the consolidated subsidiary on the accompanying consolidated balance sheet was reduced to zero on the transaction date to reflect the Company’s increased ownership percentage, with the excess of the non-controlling interest balance on the date of the acquisition over the $1.1 million purchase price recorded as additional paid-in capital.

Non-controlling interest represents the minority shareholders’ proportionate share of the Company’s majority owned subsidiary, Brightcove KK. The following table sets forth the changes in non-controlling interest for the year ended December 31, 2013:


	Year Ended December 31, 2013
Balance at beginning of period	$	1,842
Net income attributable to non-controlling interest in consolidated subsidiary		20

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, 2015 and 2014, 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 2014 to 2015 of $1.6 million principally relates to the current year taxable loss.

Based upon the level of historical income in Japan and future projections, the Company believes it is probable it will realize the benefits of its future deductible differences. As such, the Company has not recorded a valuation allowance against its net deferred tax assets in Japan as of December 31, 2015 and 2014.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, or ASU 2015-17, which simplifies the presentation of deferred income taxes. ASU 2015-17 requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for financial statements issued for fiscal years beginning after December 15, 2016 (and interim periods within those fiscal years) with early adoption permitted. ASU 2015-17 may be either applied prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. Company has elected to early adopt ASU 2015-17 retrospectively in the fourth quarter of 2015. As a result, the Company has reclassified $109 from current to noncurrent deferred tax assets as of December 31, 2014. There was no impact on the Company’s results of operations as a result of the adoption of ASU 2015-17.

As of December 31, 2015, the Company had federal and state net operating losses of approximately $131.5 million and $48.0 million, respectively, which are available to offset future taxable income, if any, through 2035. Included in the federal and state net operating losses are deductions attributable to excess tax benefits from the exercise of non-qualified stock options of $12.3 million and $7.8 million, respectively. The tax benefits attributable to these net operating losses will be credited directly to additional paid-in capital when realized. The Company also had federal and state research and development tax credits of $4.7 million and $2.9 million, respectively, which expire in various amounts through 2035. 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. Through June 30, 2014, the Company completed an assessment to determine whether there may have been a Section 382 ownership change and determined that it is more-likely-than-not that the Company’s net operating and tax credit amounts as disclosed are not subject to any material Section 382 limitations.

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, 2015 and 2014, the Company had no recorded liabilities for uncertain tax positions.

At December 31, 2015 and 2014, 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 2012 through 2015. 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 2010.

The Company’s current intention is to reinvest the total amount of its unremitted earnings in the local international tax jurisdiction or to repatriate the earnings only when tax effective. As such, the Company has not provided for U.S. taxes on the unremitted earnings of its international subsidiaries. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company may be subject to U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. Determination of the amount of the unrecognized deferred U.S. income tax liability is not practical due to the complexity associated with this hypothetical calculation.

Debt	12 Months Ended
Debt	Dec. 31, 2015
Debt Disclosure [Abstract]
Debt	10. Debt On November 19, 2015, the Company entered into a loan and security agreement with a lender (the Loan Agreement) providing for up to a $20.0 million asset based line of credit (the Line of Credit). The Company had previously entered into a loan and security agreement dated March 30, 2011 followed by three loan modification agreements. The new Loan Agreement replaces all prior loan agreements in their entirety. Under the Line of Credit, the Company can borrow up to $20.0 million. Borrowings under the Line of Credit are secured by substantially all of the Company’s assets. Outstanding amounts under the Line of Credit accrue interest at a rate equal to the prime rate plus the prime rate margin or the LIBOR rate plus the LIBOR rate margin, as defined. Under the Loan Agreement, the Company 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 lender 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. The Company was in compliance with all covenants under the Line of Credit as of December 31, 2015. On June 1, 2015, the Company entered into an equipment financing agreement with a lender (the June 2015 Equipment Financing Agreement) to finance the purchase of $1.7 million in computer equipment and support. The liability relating to the June 2015 Equipment Financing Agreement was recorded at fair value using a market interest rate. During the quarter ended December 31, 2015, the Company returned the equipment that was originally purchased and received a refund from the vendor for all amounts paid by the Company under the June 2015 Equipment Financing Agreement. As part of this transaction, the vendor repaid the outstanding debt obligation on behalf of the Company. There are no amounts outstanding as of December 31, 2015.
