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. 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 there are no material recognized or unrecognized subsequent events.

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, 2016 or 2015.

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, 2016 and 2015 consist of the following:


	December 31, 2016
Description	Contracted Maturity		Amortized Cost		Fair Market Value		Balance Per Balance Sheet
Cash		Demand	$	23,942	$	23,942	$	23,942
Money market funds		Demand		12,871		12,871		12,871

Total cash and cash equivalents			$	36,813	$	36,813	$	36,813


	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

Restricted Cash

At December 31, 2015, 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. During 2016, the collateral for the letter of credit related to the contractual provisions of the Company’s corporate credit cards was released, which eliminated the restricted cash balance.

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, 2016 and 2015, 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 guidance also eliminated 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, 2016, 2015 and 2014:


	Balance at Beginning of Period		Provision		Write-offs			Balance at End of Period
Year ended December 31, 2016	$	332	$	230	$	(408	)	$	154
Year ended December 31, 2015		181		408		(257	)		332
Year ended December 31, 2014		461		118		(398	)		181

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, 2016, 2015 and 2014, no individual customer accounted for more than 10% of total revenue.

As of December 31, 2016 and 2015, 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, 2016, 2015 and 2014, the Company capitalized $4,038, $1,488 and $474, respectively, of internal-use software development costs. The Company recorded amortization expense associated with its capitalized internal-use software development costs of $690, $469 and $397 for the years ended December 31, 2016, 2015 and 2014, 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,
			2016		2015
Computer equipment		3	$	18,750	$	20,459
Software		3 - 6		14,648		10,766
Furniture and fixtures		5		1,995		1,942
Leasehold improvements		Shorter of lease term or the estimated useful life		1,202		1,059

				36,595		34,226
Less accumulated depreciation and amortization				27,331		25,537

			$	9,264	$	8,689

Depreciation and amortization expense, which includes amortization expense associated with capitalized internal-use software development costs, for the years ended December 31, 2016, 2015 and 2014 was $4,680, $5,575 and $5,387, respectively.

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

On December 31, 2015, the Company entered into an equipment financing agreement with a lender (the “December 2015 Equipment Financing Agreement”) to finance the purchase of $604 in computer equipment. In February 2016, the Company drew down $604 under the December 2015 Equipment Financing Agreement. Refer to Note 9 for a discussion of the equipment financing.

On December 31, 2016, the Company disposed of a cost value of $1.9 million in computer equipment in connection with the closure of certain facilities for the purpose of consolidating its data centers. The Company recorded cost of revenue of $845, of which $695 represented the settlement amount due upon signing a termination agreement relating to the facilities and $150 represented a loss on disposal of assets in connection with the closure of the facilities.

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, 2016, 2015 and 2014, 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, 2016 and 2015.

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, 2016 and 2015, 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, 2016 and 2015.

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 potentially dilutive common shares have been excluded from the computation of dilutive net loss per share as of December 31, 2016, 2015 and 2014, as their effect would have been antidilutive:


	Year Ended December 31,
	2016		2015		2014
Options outstanding		4,291		4,139		3,805
Restricted stock units outstanding		1,668		1,043		990
Warrants		19		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, 2016 or 2015.

Stock-Based Compensation

At December 31, 2016, 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, 2014, 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% for each of the years ended December 31, 2016, 2015 and 2014 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, 2016, 2015 and 2014, was $4.01, $3.10 and $4.21 per share, respectively. The weighted-average assumptions utilized to determine such values are presented in the following table:


	Year Ended December 31,
	2016			2015			2014
Risk-free interest rate		1.75	%		1.96	%		2.16	%
Expected volatility		45	%		46	%		52	%
Expected life (in years)		6.2			6.2			6.2
Expected dividend yield		—			—			—

As of December 31, 2016, there was $13,327 of total unrecognized stock-based compensation expense related to stock based awards that is expected to be recognized over a weighted-average period of 2.48 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, 2016, 2015 and 2014, 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, 2016, 2015 and 2014, total stock-based compensation expense was $6,012, $6,014 and $6,387, 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, 2016.

Advertising Costs

Advertising costs are charged to operations as incurred. The Company incurred advertising costs of $2,137, $2,081 and $3,515 for the years ended December 31, 2016, 2015 and 2014, respectively.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which modifies how all entities recognize revenue, and consolidates into one ASC Topic (ASC Topic 606, Revenue from Contracts with Customers) the current guidance found in ASC Topic 605, and various other revenue accounting standards for specialized transactions and industries. ASU 2014-09 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. ASU 2014-09 may be applied using either a full retrospective approach, under which all years included in the financial statements will be presented under the revised guidance, or a modified retrospective approach, under which financial statements will be prepared under the revised guidance for the year of adoption, but not for prior years. Under the latter method, entities will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the entity at the date of adoption.

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, which defers the effective date of ASU 2014-09 by one year. ASU 2014-09 is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. The Company has developed an implementation plan to adopt this new guidance. As part of this plan, the Company is currently assessing the impact of the new guidance on its results of operations. Based on the Company’s procedures performed to date, nothing has come to its attention that would indicate that the adoption of ASU 2014-09 will have a material impact on its revenue recognition on cloud offerings, however, further analysis is required and the Company will continue to evaluate this assessment in 2017. While the Company is still evaluating the impact that this guidance will have on its financial statements and related disclosures, the Company’s preliminary assessment is that there will be an impact relating to the accounting for costs to acquire a contract. Under the standard, the Company will be required to capitalize certain costs, primarily commission expense to sales representatives, on its consolidated balance sheet and amortize such costs over the period of performance for the underlying customer contracts. The Company is still evaluating the impact of capitalizing costs to execute a contract.

The Company intends to adopt ASU 2014-09 on January 1, 2018. The Company currently expects to apply the modified retrospective method of adoption; however, it has not yet finalized its transition method, but expects to do so in 2017 upon completion of further analysis.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share based payments, including income tax consequences, classification of awards as either equity or liabilities, an option to make a policy election to recognize gross share based compensation expense with actual forfeitures recognized as they occur as well as certain classification changes on the statement of cash flows. This guidance is effective for annual and interim reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact that adopting ASU 2016-09 will have on its consolidated financial statements and related disclosures. The Company does not believe that the impact of recording actual forfeitures as they occur, rather than estimating forfeitures by applying a forfeiture rate, will result in a significant impact to accumulated deficit upon recording the cumulative effect adjustment.

In February 2016 the FASB issued 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. In addition, ASU 2016-02 requires the use of the modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. This guidance is effective for annual and interim periods beginning after December 15, 2018 and requires retrospective application. The Company is currently assessing the impact that adopting ASU 2016-02 will have on its consolidated financial statements and related 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.

Intangible Assets and Goodwill

4. Intangible Assets and Goodwill

On March 10, 2016, the Company purchased an intangible asset for $300 plus a contingent amount of up to an additional $250 to be determined on the 90^th day following the closing date. In June 2016, it was determined that no additional consideration was to be provided in connection with the intangible asset purchase. The useful life of the intangible asset was determined to be three years. As of December 31, 2016, the net carrying value of the intangible asset was $219.

Finite-lived intangible assets consist of the following as of December 31, 2016.

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, 2016 and 2015:


	December 31, 2016
	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	$	12,871	$	—	$	—	$	12,871

Total assets	$	12,871	$	—	$	—	$	12,871

Total assets	$	9,580	$	201	$	—	$	9,781

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, 2016 or 2015.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Certain amounts included in the table above relating to co-location leases for the Company’s servers include usage based charges in addition to base rent.

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 $2,404.

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, 2016 and 2015, the Company had deferred rent and rent incentives of $1,579 and $1,653, respectively, of which $1,320 and $1,565, respectively, is classified as a long-term liability in the accompanying consolidated balance sheets. Rent expense for the years ended December 31, 2016, 2015 and 2014 was $6,334, $6,831 and $6,280, respectively. Income from sublease rental activity amounted to $219, $185 and $0, respectively, for the years ended December 31, 2016, 2015 and 2014.

In addition to the operating obligations noted in the table above, as of December 31, 2016, the Company recorded cost of revenue of $845 of which $695 represented the settlement amount due upon signing a termination agreement relating to the facilities and $150 represented a loss on disposal of assets in connection with the closure of the facilities for the purpose of consolidating data centers.

Capital Lease Commitments

The Company leases certain computer equipment and support under non-cancelable capital leases. The lease arrangements expire at various dates through September 2018. Future minimum rental commitments under capital leases at December 31, 2016 are as follows:


Year Ending December 31,	Capital Lease Commitments
2017	$	508
2018		231
Less – interest on capital leases		21

	$	718

At December 31, 2016, total assets under capital leases were $1.2 million and related accumulated amortization was $557,000.

In addition to the operating lease and capital lease commitments discussed above, as of December 31, 2016, the Company had non-cancelable commitments of $9,876, $10,996 and $6,942 payable in 2017, 2018 and 2019, respectively, primarily for content delivery network services, hosting and other support services. In January 2017, the company entered into an agreement with a non-cancelable commitment, primarily for content delivery and network storage service, of $15.8 million through December 31, 2018.

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 July 8, 2016, a complaint was filed by Brand Technologies, Inc. naming the Company, along with several others, as a defendant in a case alleging copyright infringement, violations of the Lanham Act, unfair competition and related claims (Brand Technologies, Inc. v. Cox Enterprises, Inc., et al., United States District Court for the Central District of California). The complaint alleges that Cox Media Group (CMG) engaged in the unlicensed provision of copyrighted videos, acquired from AOL and owned by the plaintiff, on CMG websites by using a Brightcove technology. The complaint seeks actual and statutory damages, costs and injunctive relief. Brightcove is being indemnified in this matter. 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.

On July 30, 2016, a complaint was filed by Autumn Cloud LLC naming the Company as a defendant in a patent infringement case (Autumn Cloud LLC v. Brightcove Inc., United States District Court for the Eastern District of Texas). The complaint alleged that Brightcove infringed U.S. Patent 7,606,843 with an issue date of October 20, 2009, entitled “System and Method for Customizing the Storage and Management of Device Data in a Networked Environment,” and U.S. Patent 8,239,347 with an issue date of August 7, 2012, entitled “System and Method for Customizing the Storage and Management of Device Data in a Networked Environment.” The complaint sought monetary damages and declarations of infringement. Brightcove acquired a license to the patents-in-suit via a third-party and as a result the complaint has been dismissed with prejudice. Brightcove did not incur any loss in this matter.

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, 2016, 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, 2016 and 2015 with a cost of $871. See Note 3 for additional information.

Equity Incentive Plans

At December 31, 2016, 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 were 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, 2016, 945,238 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, 2016:


	Number of Shares			Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value ⁽²⁾
Outstanding at December 31, 2015		4,622,886		$	6.63
Granted		816,902			8.83
Exercised		(886,085	)		5.14			$	5,159
Cancelled		(403,119	)		8.84

Outstanding at December 31, 2016		4,150,584		$	7.17		7.14	$	7,107

Exercisable at December 31, 2016		1,923,596		$	6.49		5.37	$	4,867

Vested or expected to vest at December 31, 2016 ⁽¹⁾		3,612,724		$	7.08		6.87	$	6,577

(1)	This represents the number of vested options as of December 31, 2016 plus the number of unvested options expected to vest as of December 31, 2016, based on the unvested options outstanding at December 31, 2016 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, 2016 of $8.05 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, 2015 and 2014 was $281 and $1,499, 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, 2016:


	Shares			Weighted Average Grant Date Fair Value
Unvested by December 31, 2015		1,503,814		$	6.69
Granted		1,061,958			9.77
Vested and issued		(425,898	)		7.35
Cancelled		(237,297	)		7.59

Unvested by December 31, 2016		1,902,577		$	7.84

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 were 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. In August 2016, the remaining 28,028 shares exercisable under the warrants were exercised pursuant to a net exercise provision, which resulted in the issuance of 20,528 common shares.

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, 2016 and 2015, 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 2015 to 2016 of $3.9 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, 2016 and 2015.

As of December 31, 2016, the Company had federal and state net operating losses of approximately $155.5 million and $57.4 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 $16.9 million and $10.2 million, respectively. The Company also had federal and state research and development tax credits of $5.4 million and $3.5 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, 2016 and 2015, the Company had no recorded liabilities for uncertain tax positions.

At December 31, 2016 and 2015, 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 2016. 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, 2016
Debt Disclosure [Abstract]
Debt	9. Debt On November 19, 2015, the Company entered into an amended and restated 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”). 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, excluding intellectual property. Outstanding amounts under the Line of Credit accrue interest at a rate equal to the prime rate or the LIBOR rate plus 2.5%. 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, 2016. As the Company has not drawn on the Line of Credit, there are no amounts outstanding as of December 31, 2016. On December 31, 2015, the Company entered into an equipment financing agreement with a lender (the “December 2015 Equipment Financing Agreement”) to finance the purchase of $604 in computer equipment. In February 2016, the Company drew down $604 under the December 2015 Equipment Financing Agreement, and the liability was recorded at fair value using a market interest rate. The Company is repaying its obligation over a two year period through January 2018, and the amount outstanding was $333 as of December 31, 2016.
