Organization, Basis of Presentation and Summary of Significant Accounting Policies

1. Organization, Basis of Presentation and Summary of Significant Accounting Policies

Envivio, Inc. (the “Company”) was incorporated in the state of Delaware on January 5, 2000. The Company is a leading provider of IP video processing and distribution solutions to mobile and broadband service providers, cable multiple system operators, direct broadcast satellite service providers and content providers, which includes broadcasters and content publishers, owners, aggregators and licensees. The Company is headquartered in San Francisco, California and maintains operations in North America, Europe (including research and development operations in France) and the Asia Pacific region.

Basis of Presentation

The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenue recognition, allowances for doubtful accounts, valuation of deferred inventory costs, useful lives of property and equipment, valuation of deferred tax assets and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments of the carrying values of assets and liabilities. Actual results could differ materially from these estimates.

Risks and Uncertainties

The Company is subject to a number of risks similar to other comparable companies in the video processing and distribution industry. These risks include, but are not limited to, the level of capital spending by telecommunications, cable and satellite service provider, as well as, more recently, the emerging broadcast, media and Internet content providers, its reliance on channel partners, a lengthy sales cycle, dependence on the development of new products and services, unfavorable economic and market conditions, competition from larger and more established companies, limited management resources, dependence on a single contract manufacturer and a limited number of suppliers, and the rapidly changing nature of the video processing and distribution industry. Failure by the Company to anticipate or to respond adequately to technological developments in its industry, changes in customer or supplier requirements, changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of products could have a material adverse effect on the Company’s operating results, financial condition and cash flows.

Cash and Cash Equivalents

The Company considers all highly liquid marketable securities purchased with an original maturity of 90 days or less at the time of purchase to be cash equivalents. Cash and cash equivalents is comprised of demand deposits and money market funds and is stated at amounts that approximate fair value.

On July 31, 2012, the Company amended its revolving line of credit agreement with a commercial lender to increase the amount available from $5.0 million to $10.0 million for general corporate purposes and to extend the maturity date to July 2014. Under the terms of this amendment, interest accrued at a floating per annum rate equal to the greater of either (x) the prime rate plus 0.75% or (y) 4.00% and the Company was required to pay commitment fees of $25,000 per year. The Company was subject to financial covenants requiring the Company to maintain a ratio of unrestricted cash, cash equivalents and eligible accounts receivable to current liabilities less deferred revenue of at least 1.50 to 1.00. The line of credit expired on July 31, 2014 and the Company did not renew the line of credit. The Company does not have an outstanding balance and has not drawn down any outstanding amount on this line of credit as of January 31, 2015.

In October 2014, the Company entered into an irrevocable standby letter of credit relating to the new San Francisco office lease. The standby letter of credit protects the lessor by ensuring the full and faithful performance by the Company of all its obligations and for all losses and damages the lessor may suffer as a result of any breach or default by the Company under the lease. The letter of credit is for $329,000, payable in the City of San Francisco, California and provides for a right to transfer the letter of credit to another party, person or entity and requires the Company to replenish any amounts drawn down by the lessor pursuant to its rights under the lease agreement.

Accounts Receivable and Allowances for Doubtful Accounts

Trade accounts receivable are recorded at invoiced amounts and do not bear interest. The Company does not require collateral and performs ongoing credit evaluations of its customers and provides an allowance for expected losses. The Company maintains an allowance for doubtful accounts based upon the age of its accounts receivable, current economic trends, credit-worthiness of the customers and customer payment history. The Company writes off accounts receivable against the allowance when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. The following table presents the changes in the allowance for doubtful accounts (in thousands):

Concentration of Risks

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents consist of money market funds and demand deposits with financial institutions which may exceed Federal Deposit Insurance Corporation (“FDIC”) limits. The Company has not experienced any losses related to its cash and cash equivalents. One customer accounted for 19% of accounts receivable as of January 31, 2015 and two customers accounted for 11% and 10% of accounts receivable as of January 31, 2014.

Customers representing 10% or greater of total revenue for the periods presented were as follows (in percentages):

less than 10%

Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers as well as licenses for the Company’s monitoring system. In addition, the Company relies on a single third party to manufacture its products. Although the Company seeks to reduce dependence on those sole source and limited source suppliers and its manufacturer, the partial or complete loss of certain of these sources could have a material adverse effect on the Company’s operating results, financial condition and cash flows, and damage its customer relationships.

Inventories

Inventories are valued at the lower of average cost or market value. Inventories are comprised of hardware and related component parts of its finished goods. The Company establishes provisions for excess and obsolete inventories after evaluating historical sales, future demand, market conditions, expected product lifecycles and current inventory levels to reduce such inventories to their estimated net realizable value.

Deferred Inventory Costs

Deferred inventory costs represent the costs of products that have been delivered to the customer for which product revenue associated with the arrangement has been deferred as a result of not meeting the revenue recognition criteria. The deferred inventory costs are recognized as costs of revenue when the related revenue is recognized.

Property and Equipment, net

Property and equipment, net, is stated at historical cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally two to five years. Leasehold improvements are recorded at cost with any reimbursement from the landlord being accounted for as deferred rent, which is amortized using the straight-line method over the lease term. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the lease term. Costs of demo inventory held by the Company’s customers are also included within property and equipment. Demo inventory is depreciated over an estimated useful life of two years. Expenditures for maintenance and repairs are expensed as incurred.

Impairment of Long-lived Assets

The Company evaluates its long-lived assets for indicators of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment exists if the carrying amounts of such assets exceed the estimates of future net undiscounted cash flows expected to be generated by such assets. Should an impairment exist, the impairment loss would be measured based on the excess of the carrying value of the asset over the estimated fair value of the asset. As of January 31, 2015 and 2014, the Company has not written down any of its long-lived assets as a result of an impairment.

Revenue Recognition

The Company derives revenue from the sale of its IP video processing and distribution solutions which consist of hardware and integrated software, that is essential to the functionality of the hardware the Company sells, and stand-alone software. The Company also derives revenue from related professional services and support and maintenance agreements.

The Company recognizes revenue only when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is deemed probable. The Company evaluates each of these criteria as follows:

•

Evidences of an arrangement — Contracts or customer purchase orders are used to determine the existence of an arrangement.

•

Delivery — Delivery is considered to occur when title has been transferred, except in instances when final acceptance of the product, system or solution is specified by the customer. In these instances, revenue is deferred until acceptance criteria have been met. In the case of electronic delivery of the licensed software, title transfers when the customer is given access to download the software.

•

Fixed or determinable fee — The Company assesses whether fees are fixed or determinable at the time of sale. The Company only considers the fee to be fixed or determinable if the fee is not subject to refund or adjustment. The Company’s payment terms may vary based on the country in which the agreement is executed and the credit standing of the individual customer, among other factors. If the arrangement fee is not fixed or determinable, revenue is recognized as amounts become due and payable.

•

Collection is deemed probable — Collection is deemed probable if the Company expects that the customer will be able to pay amounts under the arrangement as payments become due. If the Company determines that collection is not probable, revenue is deferred until cash collection.

In October 2009, the Financial Accounting Standards Board (“FASB”) amended the accounting standards for revenue recognition to remove from the scope of industry-specific software revenue recognition guidance, any tangible products containing software components and non-software components that operate together to deliver the product’s essential functionality. In addition, the FASB amended the accounting standards for certain multiple element revenue arrangements to:

•

Provide updated guidance on whether multiple elements exist, how the elements in an arrangement should be separated, and how the arrangement consideration should be allocated to the separate elements;

•

Provide for price hierarchy, where the selling price for an element is based on vendor specific objective evidence (“VSOE”), if available; third-party evidence (“TPE”), if available and VSOE is not available; or the best estimate of selling price (“BESP”), if neither VSOE nor TPE is available;

•

Eliminate the use of the residual method and require an entity to allocate arrangement consideration using the selling price hierarchy.

The new accounting guidance was adopted by the Company on a prospective basis at the beginning of the fiscal year ending January 31, 2012 for all transactions, except for stand-alone sales of software, entered into or materially modified on or after February 1, 2011.

The Company enters into multiple element revenue arrangements in which a customer may purchase a combination of hardware, software, hardware and software maintenance, professional services and training. The Company accounts for multiple agreements with a single customer as one arrangement if the contractual terms or substance of those agreements indicate that they may be so closely related that they are, in effect, parts of a single arrangement.

For stand-alone software arrangements, the Company allocates revenue for arrangements with multiple deliverables, such as sales of our solution with software that include support or other professional services, to the delivered elements of the arrangement using the residual value method based on VSOE of fair value of the undelivered items. VSOE of fair value for undelivered elements is determined based upon prices paid by the customers for the separate renewal or sales of such services.

For transactions, other than stand-alone sales of software, entered into on or subsequent to February 1, 2011, the Company allocates the arrangement fee to each element based upon the relative selling price of such element and, if software and software-related elements, such as maintenance for the software elements, are also included in the arrangement, the Company allocates the arrangement fee to each of those software and software-related elements as a group based on its BESP for those elements. When applying the relative selling price method, the Company determines the selling price for each element using VSOE of selling price, if it exists, or TPE of selling price, if it exists and VSOE does not exist. If neither VSOE nor TPE of selling price exist for an element, the Company uses its BESP for that element. The revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for that element. The manner in which the Company accounts for multiple element arrangements that contain only software and software-related elements remains unchanged.

Consistent with the Company’s methodology under previous accounting guidance, it determines VSOE for each element based on historical stand-alone sales to third parties. For hardware and software maintenance and professional services, the Company determines the VSOE of fair value based on the Company’s history of stand-alone sales demonstrating that a substantial majority of transactions fall within a narrow range for each service offering.

The Company is presently not able to determine TPE for its products, maintenance or professional services. TPE is determined based on competitor prices for similar elements when sold separately. The Company’s offerings contain a significant level of differentiation such that comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company’s go-to-market strategy differs from that of its peers and it is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis.

When the Company is unable to establish the selling price of an element using VSOE or TPE, it uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The Company determines BESP for a product or service by considering multiple factors including, but not limited to, historical pricing practices by geography, customer class and distribution channel and gross margin objectives.

The Company regularly reviews VSOE and BESP data provided by actual transactions to update these estimates and the relative selling prices allocated to each element.

Revenue from support and maintenance agreements is recognized ratably over the term of the maintenance agreement, which is typically one year, and the Company defers the unrecognized revenue portion of the maintenance agreements. The Company recognizes revenue from professional services upon performance of the services and recognizes costs associated with services as incurred.

Shipping and Handling Costs

Shipping and handling costs incurred for inventory purchases and product shipments are recorded in cost of revenue in the Company’s consolidated statements of operations.

Deferred Revenue

A portion of the Company’s deferred revenue represents customer payments made in advance for support and maintenance contracts because the Company typically bills support contracts on an annual basis in advance and recognizes the associated revenue ratably over the support period, which can range from one to four years.

Deferred revenue also includes arrangements where final acceptance of the product, system or solution is specified by the customer, and the recognition of revenue for these arrangements is deferred until all acceptance criteria are met.

Deferred Rent

The Company recognizes rental expense on a straight-line basis over the lease term, and records the difference between rent expense and the amounts currently paid and payable as deferred rent. The cost of leasehold improvements paid by the Company’s landlord and repayable to the landlord are also included in deferred rent.

Capitalized Software Development Costs

The Company charges product development costs to expense as incurred until technological feasibility is attained and all other research and development activities for the hardware components of the product have been completed. Technological feasibility is attained when the planning, design and testing phases related to the development of the Company’s software have been completed and the software has been determined viable for its intended use. The time between the attainment of technological feasibility and the completion of software development has historically been relatively short with immaterial amounts of development costs incurred during this period. Accordingly, the Company has not capitalized any software development costs.

Foreign Currency Translation

For each of the Company’s foreign subsidiaries, the functional currency is its local currency. Assets and liabilities of foreign operations are translated into U.S. dollars using period-end exchange rates, and revenues and expenses are translated into U.S. dollars using average exchange rates in effect during each period. The effects of foreign currency translation adjustments are included in accumulated other comprehensive loss, a separate component of stockholders’ equity. Also recorded as foreign currency translation adjustments are transaction gains and losses on long-term intercompany balances for which settlement is not planned or anticipated in the foreseeable future.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where, based upon the available evidence, management concludes that it is more likely than not that the deferred tax assets will not be realized.

The Company follows the accounting guidance for accounting for uncertainty in income taxes. The accounting guidance requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the benefit recognized and measured and the tax position taken or expected to be taken on the Company’s tax return. To the extent that the assessment of such tax positions change, the change in estimate is recorded in the period in which the determination is made. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that the tax return positions are fully supportable. The reserves are adjusted in light of changing facts and circumstances, such as the outcome of a tax audit. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate.

The Company recognizes interest and penalties related to unrecognized tax benefits within the provision for income taxes in the accompanying consolidated statements of operations. Accrued interest and penalties are included within other non-current liabilities in the consolidated balance sheets.

Warranty

The Company provides a warranty for its products, software and services. The initial warranty period for all products commences on the date of purchase and continues in effect for the following consecutive 12 months for hardware and 90 days for software. The warranty period can be extended if the customer has purchased a support agreement. The warranty period continues for the duration of a valid support agreement between the Company and the customer under which the payment of support and maintenance fees is current. To date, the Company’s warranty expense has not been significant. Therefore, the Company did not provide for a warranty accrual as of January 31, 2015 and 2014.

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based payment awards made to employees and directors based on the estimated fair value of the awards on the date of grant. The Company determines the grant date fair value of the awards using the Black-Scholes option-pricing model and recognizes the related stock-based compensation generally on a straight-line basis over the vesting period of the awards. The Company uses a modified binary option pricing model (European, call option) to establish the expected value of restricted stock awards with market and performance vesting conditions. Stock-based compensation expense is based on the value of the portion of the stock-based payment awards that are ultimately expected to vest. As such, the Company’s stock-based compensation expense is reduced for the estimated forfeitures and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Comprehensive Loss

Comprehensive loss is comprised of net loss and other comprehensive loss. For the Company, other comprehensive loss includes foreign currency translation adjustments and unrealized gains and losses on investments. The changes in the components of accumulated comprehensive loss have been disclosed in the consolidated statements of stockholders’ equity (deficit) and comprehensive loss.

Fair Value Measurements

The Company measures and reports its cash equivalents, short-term investments and preferred stock warrant liabilities at fair value. The accounting guidance for fair value measurements provides a framework for measuring fair value and expanding related disclosures. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The guidance also establishes a hierarchy which requires an entity to maximize the use of observable inputs, when available. The guidance requires that each fair value measurement be classified and disclosed in one of the following three categories:

•

Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities.

•

Level 2: Observable inputs (other than Level 1 prices) such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly.

•

Level 3: Unobservable inputs that involve management judgment and are supported by little or no market activity.

The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s Level 1 assets consist of its money market accounts. The Company does not have level 2 and level 3 categories.

Foreign Tax Credits

The Company’s foreign tax credit asset consists primarily of amounts due from the Government of France for research and development incentives provided to the Company’s French subsidiary. The French research tax credit is general and does not target any specific sector or type of company. Eligible expenditures include human and material resources allocated to research and development, subcontracted research and development costs, technological costs and patent protection. The amounts due from the Government of France are determined on a cost reimbursement basis. The French research tax credit is deducted from the French tax to be paid, or in the event taxes are not due is refunded. As the French research tax credit is related to the Company’s research and development expenditures and is refundable regardless of whether any French tax is owed, the credits earned of $2.8 million, $2.7 million and $1.6 million during the years ended January 31, 2015, 2014 and 2013, respectively, were recorded as a reduction of research and development expenses.

Common Stock

The Company is authorized to issue 100,000,000 shares of common stock as a result of the Company’s initial public offering in April 2012. All previously outstanding classes of common stock and all outstanding classes of preferred stock were converted on a one to one basis to shares of common stock.

Net Income (Loss) per Share of Common Stock

Basic net income (loss) per share is calculated by dividing the net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Net income (loss) attributable to common stockholders is calculated using the two class method, by subtracting from net income (loss) the noncumulative dividends on all outstanding shares of convertible preferred stock and the accretion of the redeemable convertible preferred stock to its redemption amount, to reflect the rights of the preferred stockholders to receive dividends in preference to common stock.

The diluted net income (loss) per share attributable to common stockholders is computed by giving effect to all potential common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, convertible preferred stock, stock options to purchase common stock, stock purchase rights and warrants to purchase convertible preferred stock and common stock are considered to be common stock equivalents but have been excluded from the calculation of diluted net income (loss) per share attributable to common stockholders as their effect is not dilutive.

Recent Accounting Pronouncements

In April 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance is effective for the Company beginning in the first quarter of the fiscal year ended January 31, 2016. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its financial position, results of operations or cash flows.

In May 2014, he FASB issued ASU 2014-09 regarding the Accounting Standards Codification (“ASC”) Topic 606 “Revenue from Contracts with Customers.” This ASU provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU will be effective for the Company’s fiscal year beginning February 1, 2017. Early adoption is not permitted. The Company is currently evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

In November 2014, the FASB issued ASU No. 2014-16 (“ASU 2014-16”), “Derivatives and Hedging (Topic 815) — Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity”. ASU 2014-16 was issued to clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risk of a host contract in a hybrid financial instrument that is issued in the form of a share. In addition, ASU 2014-16 was issued to clarify that in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (that is, the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. ASU 2014-16 is effective with fiscal years beginning after December 15, 2015. Early adoption in an interim period is permitted. The Company is currently evaluating the impact of the adoption of ASU 2014-16 on its consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810) — Amendments to the Consolidation Analysis”, intended to improve targeted areas of consolidation guidance for all entities. ASU 2015-02 is effective with fiscal years beginning after December 15, 2015. Early adoption in an interim period is permitted. The Company is currently evaluating the impact of the adoption of ASU 2015-02 on its consolidated financial statements.

The Company has classified all available-for-sale securities with readily available markets as short-term, regardless of whether the stated maturity is greater than one year from the current balance sheet date, because of the Company’s intent to sell those securities as necessary. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive loss in stockholders’ equity. For the periods presented, realized and unrealized gains and losses on investments were not material. Amounts reclassified out of accumulated other comprehensive loss due to sales or maturities of investments are reflected in interest income (expense), net, in the statements of operations and were not material. An impairment charge is recorded in the consolidated statements of operations for declines in fair value below the cost of an individual investment that are deemed to be other than temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline, as well as the Company’s intent and ability to hold, or plans to sell, the investment.

	The Company did not have any debt outstanding as of January 31, 2015 and January 31, 2014.

	Line of Credit

	In November 2010, the Company entered into a revolving line of credit with a commercial lender that allowed for draws of up to $5.0 million for general corporate purposes. Amounts borrowed were to be repaid prior to the maturity date in November 2012. Interest accrued at a floating per annum rate equal to either the (i) greater of (x) the prime rate plus 2.75% or (y) 6.75% if the liquidity ratio for the immediately preceding month did not meet a minimum threshold or (ii) greater of (x) the prime rate plus 1.75% or (y) 5.75% in all other instances. The Company paid commitment fees in the amount of $106,000 and a good faith deposit of $25,000 to facilitate the agreement. The lender for this line of credit had a first priority perfected security interest in all of the Company’s assets. The credit facility contained financial covenants which effectively required the Company to maintain no less than $1.0 million in outstanding borrowings throughout the term of the arrangement as well as maintain a ratio of unrestricted cash and eligible accounts receivable to current liabilities of at least 1.50 to 1.00.

	On July 31, 2012, the Company amended its revolving line of credit agreement with a commercial lender to increase the amount available from up to $5.0 million to $10.0 million for general corporate purposes and extend the maturity date to July 2014. Under the terms of this amendment, interest accrues at a floating per annum rate equal to the greater of either (x) the prime rate plus 0.75% or (y) 4.00% and the Company is required to pay commitment fees of $25,000 per year. The line of credit expired in July 2014.

	The Company does not have an outstanding balance and did not draw down any outstanding amount on this line of credit during the year ended January 31, 2015. The line of credit expired in July 2014 and the Company did not renew it.

	In October 2014, the Company entered into an irrevocable standby letter of credit relating to the new San Francisco office lease. The standby letter of credit protects the lessor by ensuring the full and faithful performance by the Company of all its obligations and for all losses and damages the lessor may suffer as a result of any breach or default by the Company under the lease. The letter of credit is for $329,000, payable in the City of San Francisco, California and provides for a right to transfer the letter of credit to another party, person or entity as well as requires the Company to replenish any amounts drawn down by the lessor pursuant to its rights under the lease agreement. The letter of credit is secured by a $329,000 deposit, which is classified as restricted cash on the balance sheet as of January 31, 2015.



	Other Non-current Liabilities

	The Company receives repayable research grants from regional French governmental agencies to fund research and development activities. The French governmental research grants payable were $125,000, included in accrued liabilities as of January 31, 2015 and $447,000, included in both accrued liabilities and other non-current liabilities as of January 31, 2014.

	Rental expense totaled $1.2 million, $1.1 million and $1.2 million for the years ended January 31, 2015, 2014 and 2013, respectively.

	Litigation Matters

	On October 5, 2012 a complaint captioned Wiley v. Envivio, Inc., et al. CIV-517185 was filed in the Superior Court of California, County of San Mateo, naming as defendants the Company, each of its directors, its chief executive officer, its chief financial officer, and certain underwriters of its IPO. The lawsuit purports to be a class action on behalf of purchasers of shares issued in the IPO and generally alleges that the registration statement for the IPO contained materially false or misleading statements. The complaint purports to assert claims under the Securities Act of 1933, as amended, and seeks unspecified damages and other relief. On October 19, 2012 a similar complaint captioned Toth v. Envivio, Inc. et al. CIV-517481 was filed in the same court. On November 2, 2012 defendants removed the cases to the United States District Court for the Northern District of California where they were assigned case numbers 12-cv-05637-CRB and 12-cv- 05636-CW. A similar complaint was filed in the United States District Court for the Northern District of California on December 20, 2012 entitled Thomas v. Envivio, Inc., et al. C 12-06464. The Wiley and Toth actions were subsequently remanded to the San Mateo Superior Court, where they are now pending, and the Thomas case was voluntarily dismissed without prejudice. On February 28, 2014, a complaint was filed in the United States District Court for the Northern District of California entitled Gary Silverberg v. Envivio, Inc. et al., Civil No. 14-cv-00933-PJH. The complaint purports to be on behalf of a class of purchasers of the Company’s securities between April 25, 2012 and September 7, 2012. It names as defendants the Company and the Company’s chief executive officer and chief financial officer, and seeks unspecified damages and other relief for alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. On June 25, 2014, the Silverberg case was voluntarily dismissed without prejudice. In November 2014, the Company and the named defendants reached an agreement in principle to settle the above-described actions without any admission of any wrongdoing by the Company or any of the named defendants. The parties subsequently entered into a formal settlement agreement, which must be approved by the court before becoming final. The agreement requires the Company to contribute approximately $1.0 million toward the settlement. On March 16, 2015, the Company funded into an escrow account its portion of the settlement of approximately $1.0 million, and the remaining settlement payment will be covered by the Company’s director and officer insurance providers. The settlement payment will be released from escrow subject to and upon final court approval of the settlement.

	The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company is not currently a party to any other litigation matters that, individually or in the aggregate, are expected to have a material adverse effect on the Company’s business, financial condition or results of operations.

	Indemnification

	The Company may in the ordinary course of business agree to defend and indemnify some customers against legal claims that the Company’s products infringe on certain U.S. patents or copyrights. To date, the Company has not been required to make any payments resulting from any such infringement, and no amounts have been accrued for such matters. Certain of the Company’s employment agreements with its officers, arrangements with members of the board of directors and the Company’s Restated Certificate of Incorporation and Bylaws, also include indemnification provisions. As a result, the Company intends to indemnify its directors and officers in connection with being named as defendants in the purported class action IPO-related litigation and other related lawsuits. In addition, pursuant to the terms of the Company’s underwriting agreement with the representatives of the several underwriters of the Company’s initial public offering, the Company may be required to indemnify the underwriters for certain matters, subject to the terms and conditions contained in the underwriting agreement and applicable law. As a result, the Company is indemnifying the underwriters for their expenses incurred in connection with being named as defendants in the purported class action IPO-related litigation. The Company expenses such costs in the period in which such costs are incurred. The terms of the Company’s indemnification obligations may vary.

At January 31, 2012, the designations and rights of the Series 1 and Series 2 common stock were identical except for their respective voting rights as the Series 1 shares did not have the right to vote, except as required by law, and the Series 2 shares were allowed one vote on all matters subject to a vote of the stockholders. The holders of common stock, including shares legally outstanding from stock purchase rights that were exercised with notes, were also entitled to receive non-cumulative dividends whenever funds were legally available and if declared by the board of directors, subject to the rights of all classes of stock outstanding.

Immediately prior to the closing of the initial public offering (“IPO”) in April 2012, all outstanding shares of convertible preferred stock converted into common stock on a one-for-one basis. In addition, the Series 1 common stock and Series 2 common stock converted into one class of common stock.

The $54.4 million in proceeds from the IPO, net of underwriters’ discounts and commissions, but before deducting offering-related expenses payable by the Company of $5.8 million, were received on April 30, 2012, which was the closing date of the IPO. The Company has blank check preferred stock authorized. The convertible preferred stock converted into 6,988,120 shares of common stock and 1,006,206 shares of Series 1 common stock and 12,909,470 shares of Series 2 common stock converted into one class of common stock. In addition to the 6,500,000 shares of common stock sold in the IPO, certain selling stockholders of the Company also sold 1,255,000 shares of common stock in the IPO. The shares sold by the selling stockholders consisted of 503,496 shares of convertible preferred stock and 751,504 shares of Series 1 and Series 2 common stock, which were converted to common stock immediately prior to the closing of the IPO.

	Stock Option Plans

	The Company adopted its stock option plan in 2000 (the “2000 Plan”). Under the 2000 Plan, as amended, the Company was able to grant options to purchase up to 1,181,689 shares of common stock to certain employees, directors and consultants. Under the terms of the 2000 Plan, the Company may grant incentive stock options (“ISO”), nonstatutory stock options (“NSO”), common stock purchase agreements (“CSPA”) and stock purchase rights (“SPR”). Such awards are exercisable at prices generally equal to the fair value of the Company’s common stock at the date of grant, as determined by the board of directors. Awards granted under the 2000 Plan generally vest over four years with a six-month cliff period and may be exercised for a period of up to ten years. Vested options generally expire 30 days after termination of employment. In December 2010, the board of directors approved a decrease in the number of shares of common stock reserved for issuance under the 2000 Plan to 644,366 shares. No shares were available for future grant under the 2000 Plan as of January 31, 2015 and 2014, due to the adoption of the stock incentive plan described below.

	The Company adopted the 2010 stock incentive plan (the “2010 Plan”) in June 2010. The 2010 Plan provides that only employees are eligible for the grant of ISOs and that employees, consultants and outside directors are eligible for the grant of NSOs. The 2010 Plan also allows for the grant of SPRs and restricted stock units (“RSU”). Awards granted under the 2010 Plan also generally vest over four years with a six-month cliff period and may be exercised for a period of up to ten years. Vested options generally expire three months after termination of employment. No shares were available for future grant under the 2010 Plan as of January 31, 2015 and 2014 due to the adoption of a new stock incentive plan as more fully described below.

	The Company adopted the 2012 stock incentive plan (the “2012 Plan”) in June 2011, as amended in April 2012. The 2012 Plan provides that only employees are eligible for the grant of ISOs and that employees, consultants and outside directors are eligible for the grant of NSOs. The 2012 Plan also allows for the grant of SPRs, RSUs and other types of equity awards. Awards granted under the 2012 Plan also generally vest over four years with a twelve-month cliff period and may be exercised for a period of up to ten years. In general, the vesting of awards granted under the 2012 Plan accelerates as to 25% of the then remaining unvested portion of the awards upon a change in control of the Company. Vested options generally expire three months after termination of employment. Shares of common stock reserved for issuance under the 2012 Plan consist of 1,409,021 and 1,003,608 shares as of January 31, 2015 and 2014, respectively. In addition, up to 1,773,879 shares subject to outstanding awards under the 2000 Plan or 2010 Plan that are subsequently forfeited or terminated for any reason before being exercised will be made available for issuance under the 2012 Plan. The number of shares that have been authorized for issuance under the 2012 Plan will be automatically increased on the first day of each fiscal year beginning in fiscal 2014 and ending in fiscal 2023, in an amount equal to the lesser of (i) 2,000,000 shares, (ii) 4% of the outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year, or (iii) another amount determined by the Company’s board of directors.

	At the beginning of fiscal 2016, the board of directors ratified an increase in the number of shares authorized for issuance under the 2012 Plan based on 4% of the outstanding shares of the Company’s common stock on the last day of fiscal year 2015, or 1,190,311 shares. These shares will be registered under the Securities Act of 1933 on Securities and Exchange Commission Form S-8 filed in conjunction with this Form 10-K.

All of the Company’s outstanding stock-based awards are exercisable at any time without regard to vesting. Accordingly shares exercised prior to vesting are included within the outstanding stock options as of each year end.

Stock Purchase Rights and Common Stock Purchase Agreements

The Company grants SPRs to its French employees and in limited past instances, CSPAs to service providers in the U.S. The SPRs and CSPAs provide the holder with a note equal to the aggregate exercise price of the related options, therefore, allowing the holder to legally exercise the related options at the time of issuance in consideration of the notes. Generally, the SPRs and CSPAs are subject to a vesting period of four years with the Company retaining the right to repurchase unvested shares at the aggregate exercise price of the underlying options. In the event that a holder’s status as an employee ceases for any reason, the notes and the related options are cancelled. As of January 31, 2015 and January 31, 2014, 392,479 shares were subject to repurchase under the provisions of the SPRs and 97,464 shares were subject to repurchase under the provisions of the CSPAs.

The notes receivable issued to employees in conjunction with the SPRs and CSPAs are secured by the underlying shares and carry interest rates ranging from 2.1% to 5.9%. While the note terms indicate that they are full recourse, the Company has not pursued recourse in instances when a note receivable balance exceeds the fair value of the shares at the date of repurchase, and accordingly, the exercises of the SPRs and CSPAs has been considered to be non-substantive. Notes receivable relating to the SPRs and CSPAs are not recorded on the consolidated balance sheet due to the non-substantive exercise consideration. Accordingly, the SPRs and CSPAs have been accounted for as stock options and are included within the outstanding stock options as of each year end.

Restricted Stock Units

The Company grants RSUs to employees, executives and directors of the Company. As of January 31, 2015 the Company had 342,408 RSUs outstanding.

Of the total RSUs outstanding, 190,896 are subject to service, market and performance-based vesting terms that include the requirement that the Company’s stock price exceed specified milestones relative to the Company’s stock price following the initial public offering and, in some cases, are subject to acceleration under certain circumstances, including a change in control. The Company uses a modified binary option pricing model (European call option) to establish the expected value of these RSUs.

During the year ended January 31, 2015, the Company recorded $80,000 of stock-based compensation related to RSUs with service, market and performance-based vesting. During the year ended January 31, 2015, the Company recorded $313,000 of stock-based compensation related to RSUs with only service-based vesting.

A summary of the Company’s restricted stock unit activity for the years ended January 31, 2013, 2014 and 2015 is presented below:

Stock-based Compensation

Total stock-based compensation expense for the years ended January 31, 2015, 2014 and 2013 is recognized in the consolidated statements of operations as follows (in thousands):



		Year Ended January 31,
		2015				2014				2013
Cost of revenue		$	34			$	3			$	5
Research and development			95				122				129

The Company uses the Black-Scholes option-pricing model to estimate the fair value of the Company’s stock options on each grant date. The Black-Scholes option-pricing model takes into account inputs such as the exercise price, the fair value of the underlying common stock at the grant date, expected term, expected volatility, risk-free interest rate and expected dividend.


	•		Expected term — The expected term represents the period that the stock-based awards are expected to be outstanding. For option grants that are considered to be “plain vanilla,” the Company used the simplified method to determine the expected term as provided by the Securities and Exchange Commission. The simplified method calculates the expected term as the average of the time-to-vesting and the contractual life of the options. For option grants that are not considered “plain vanilla,” the expected term is based on historical option exercise behavior and post-vesting cancellations of options by employees.


	•		Expected volatility — The expected volatility is a weighted average based on the stock price volatility of a basket of similar companies and the historical volatility of the Company’s share price measured from the date of the Company’s initial public offering.


	•		Risk-free interest rate — The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the awards.


	•		Expected dividend — The expected dividend is assumed to be zero as the Company has never paid dividends and has no current plans to do so.

The weighted average assumptions used to estimate the fair value of the Company’s employee stock options at the grant dates for the years ended January 31, 2015, 2014 and 2013 were as follows:



		Year Ended January 31,
		2015				2014				2013
Expected term (in years)			6.25				6.25				6.25
Volatility			65	%			57	%			57	%
Risk-free interest rate			1.97	%			1.68	%			1.2	%
Expected dividend			0	%			0	%			0	%

As of January 31, 2015, total compensation cost not yet recognized for unvested stock option grants and unvested stock awards were $1.9 million and $168,000 respectively, which are expected to be recognized over the following 3.1 years and 1.0 years based on the weighted average vesting term, respectively.

In addition to the assumptions used in the Black-Scholes option-pricing model, the Company must also estimate a forfeiture rate to calculate the stock-based compensation for the awards. The forfeiture rate is based on an analysis of actual forfeitures and the Company will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover and other factors. The rate was 1.6% during the year ended January 31, 2015.

The Company is also required to estimate the fair value of the common stock underlying the stock-based awards when performing the fair value calculations with the Black-Scholes option-pricing model. The fair value of the common stock underlying the stock- based awards for the common stock after the Company was public was determined by the Company’s board of directors using the closing price of our common stock as reported on the Nasdaq Global Market on the date of grant. The fair value of the common stock underlying the stock-based awards for the common stock before the Company was public was estimated on each grant date by the board of directors, with input from management. The board of directors is comprised of a majority of non-employee directors with significant experience in the digital media and communications software industries. Given the then absence of a public trading market of the Company’s common stock, and in accordance with the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, the board of directors exercised reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of the fair value of the common stock, including among other things, the rights, preferences and privileges of the convertible preferred stock, business performance, present value of expected future cash flows, likelihood of achieving a liquidity event, illiquidity of the Company’s capital stock, management experience, stage of development, industry information and macroeconomic conditions. In addition, the Company’s board of directors utilized independent valuations performed by an unrelated third-party specialist to assist with the valuation of the common stock; however, the Company and the board of directors have assumed full responsibility for the estimates. These third-party specialist valuations were performed as of January 31, 2010, April 6, 2011, May 15, 2011, November 30, 2011 and February 29, 2012. The board utilized the fair values of the common stock derived in the third-party valuations to set the exercise price for options granted during the years ended January 31, 2011 and 2012, and also for options granted prior to the IPO in the Company’s 2013 fiscal year. Although the board of directors continued to believe the original value of the Company’s common stock determined was appropriate based on the facts known at that time, the fair value of the underlying common stock for options granted during the years ended January 31, 2011 and 2012 was subsequently revisited by the board of directors for financial reporting purposes and reassessed on a retrospective basis so that the fair value of the underlying common stock used to calculate the related stock-based compensation expense was increased accordingly.

The total estimated fair value of employee options and stock purchase rights granted during the years ended January 31, 2015, 2014 and 2013 was $1.3 million, $1.7 million and $2.3 million, respectively. The weighted average estimated fair value of those options granted during the years ended January 31, 2015, 2014 and 2013 was determined to be $1.38, $2.72 and $2.90 per share. The intrinsic value of options exercised during the years ended January 31, 2015, 2014 and 2013 was $1.2 million, $249,000 and $2.3 million, respectively.

The total estimated fair value of employee restricted stock awards granted during the years ended January 31, 2015, 2014 and 2013 was $300,000, $300,000 and $499,000, respectively. The weighted average estimated fair value of those awards granted during the years ended January 31, 2015, 2014 and 2013 was determined to be $2.02, $2.46 and $6.47 per share, respectively.

Options Granted to Non-Employee

During the year ended January 31, 2015, the Company granted options to purchase 26,575 shares of common stock to a non-employee at an exercise price of $3.55 per share. The Company records stock-based compensation equal to the fair value of the awards in the period they vest. In connection with option granted to the non-employee, the company recognized stock-based compensation expense of $16,000 in the year ended January 31, 2015.

Reconciliations of the statutory federal income tax to the Company’s effective income tax rate during the years ended January 31, 2015, 2014 and 2013 are as follows:

Provision for income taxes			(2.5	)%			(3.0	)%			(2.3	)%


The Company provided a full valuation allowance for net operating losses, credits and other deferred tax assets for the state of California and U.S. Foreign deferred tax assets are immaterial. A valuation allowance is provided when based upon the available evidence, management concludes that it is more likely than not that some portion of the deferred tax assets will not be realized. The Company maintained a full valuation allowance as of January 31, 2013, 2014 and 2015 due to the uncertainty of realizing future tax benefits from its net operating loss carry-forwards and other deferred tax assets. The increases in the valuation allowance during the years ended January 31, 2015, 2014 and 2013 were $6.2 million, $5.5 million and $4.1 million, respectively.

As of January 31, 2015, the Company had federal net operating loss carry-forwards of $85.8 million, and California net operating loss carry-forwards of $80.6 million. The Company’s federal and state net operating loss carry-forwards begin to expire in 2021 and 2015, respectively.

As of January 31, 2015, the Company had federal foreign tax credit carry-forwards in the amount of $222,000, available to offset U.S. federal income taxes. Unutilized foreign tax credits are allowed as a business deduction upon expiration. The Company also has state research tax credit carry-forwards in the amount of $84,000 as of January 31, 2015. This credit has no expiration period and is carried forward indefinitely until utilized.

Utilization of U.S. net operating losses and tax credit carryforwards may be limited by “ownership change” rules, as defined in Section 382 of the Internal Revenue Code. Similar rules may apply under state tax laws. The Company has completed a 382 study through the year ended January 31, 2012 and accordingly has reduced its net operating loss carry-forwards for federal and state purposes by $8.6 million and $3.4 million. In addition, the Company has reduced federal research tax credit carry-forwards by $173,000. The Company has not completed a formal Section 382 study since January 2012 but has continued to monitor activities since then. In the event the Company determines that an ownership change has occurred since January 2012, the Company previously experienced an ownership change, or should experience an ownership change in the future, the amount of net operating losses and research and development credit carryovers available in any taxable year could be limited and may expire unutilized.

The table of deferred tax assets shown above does not include certain deferred tax assets at January 31, 2015 that arose directly from tax deductions related to equity compensation in excess of compensation recognized for book purposes. Additional paid in capital will be increased by approximately $0 if and when such deferred tax assets are ultimately realized.

Uncertain Tax Positions

The Company remains open for audit by the United States Internal Revenue Service and state tax authorities since inception. The Company remains open for audit by the French tax authorities for the years 2009 through 2014. Most other foreign jurisdictions have statute of limitations that range from three to six years. The Company is not currently under examination by income tax authorities in federal, state or other foreign jurisdictions.



A reconciliation of the beginning and ending balances of the gross unrecognized tax benefits during the years ended January 31, 2015, 2014 and 2013 is as follows (in thousands):



		Year ended January 31,
		2015				2014				2013
Unrecognized benefit-beginning of period		$	1,436			$	1,314			$	1,277
Gross increases-current period tax adjustments			429				342				65
Gross decreases-prior period tax adjustments			(167	)			(220	)			(28	)

Unrecognized benefit-end of period		$	1,698			$	1,436			$	1,314


As of January 31, 2015, the total amount of gross unrecognized tax benefits was $1.7 million of which $153,000 offsets tax attributes. Unrecognized tax benefits of $1.5 million, if recognized, would affect the effective income tax rate in the period or periods recognized. The net unrecognized tax benefits were included in other non-current liabilities in the consolidated balance sheet as of January 31, 2015 and 2014.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. The Company accrued net interest and penalties of $18,000, $15,000 and $15,000 during the years ended January 31, 2015, 2014 and 2013. In addition, the Company recorded liabilities for accrued interest and penalties of $67,000 and $50,000 as of January 31, 2015 and 2014.

The Company does not believe there will be an increase or decrease of unrecognized tax benefits that may occur within the next 12 months. To the extent there is an increase or decrease, the Company believes any impact to the effective tax rate would be immaterial.
