We were founded in 2007 on the premise that industry-specific cloud solutions could best address the operating challenges and regulatory requirements of the life sciences industry. Our products are designed to meet the unique needs of life sciences companies, regardless of size. Targeted to address our customers’ most strategic business functions—from research and development to commercialization—our solutions are designed to help the industry bring products to market faster and more efficiently, market and sell more effectively and maintain compliance with government regulations. We offer solutions for multichannel customer relationship management, regulated content and information management, master data management and data and data services that meet the specialized functional and compliance needs of life sciences companies. Our fiscal year end is January 31.

Principles of Consolidation and Basis of Presentation

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP). The consolidated financial statements include accounts of our wholly owned subsidiaries after elimination of intercompany accounts and transactions.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make certain estimates, judgments and assumptions that affect the consolidated financial statements and the notes thereto. These estimates are based on information available as of the date of the consolidated financial statements. On a regular basis, management evaluates these estimates and assumptions. Significant items subject to such estimates and assumptions include, but are not limited to:

the best estimate of selling price of the deliverables included in multiple-deliverable revenue arrangements;

the collectibility of our accounts receivable;

the fair value of assets acquired and liabilities assumed for business combinations;

the valuation of short-term investments and the determination of other-than-temporary impairments;

the valuation of building and land;

the realizability of deferred income tax assets and liabilities;

the fair value of our stock-based awards and related forfeiture rates; and

the capitalization and estimated useful life of internal-use software development costs.

As future events cannot be determined with precision, actual results could differ significantly from those estimates.

Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. We define the term “chief operating decision maker” to be our Chief Executive Officer. Our Chief Executive Officer reviews the financial information presented on a consolidated basis for purposes of allocating resources and evaluating our financial performance. Accordingly, we have determined that we operate in a single reportable operating segment. Since we operate in one operating segment, all required financial segment information can be found in the consolidated financial statements.

Revenue Recognition

We derive our revenues primarily from subscription services fees and professional services fees. Subscription services revenues consist of fees from customers accessing our cloud-based software solutions and subscription or license fees for our data solutions. Additionally, Zinc Ahead had entered into a limited number of perpetual license agreements prior to the acquisition that had accompanying maintenance and hosting fees. We have included such maintenance and hosting fees in our subscription services revenues. Professional services revenues consist primarily of fees from implementation services, configuration, data services, training and managed services related to our solutions. We commence revenue recognition when all of the following conditions are satisfied:

there is persuasive evidence of an arrangement;

the service has been or is being provided to the customer;

the collection of the fees is reasonably assured; and

the amount of fees to be paid by the customer is fixed or determinable.

Our subscription services arrangements are generally non-cancelable and do not provide for refunds to customers in the event of cancellations. We record revenues net of any sales taxes.

Subscription Services Revenues

Subscription services revenues are recognized ratably over the order term beginning when the solution has been provisioned to the customer. Our subscription arrangements are considered service contracts, and the customer does not have the right to take possession of the software.

Professional Services and Other Revenues

The majority of our professional services arrangements are recognized on a time and material basis. Professional services revenues recognized on a time and material basis are measured monthly based on time incurred and contractually agreed upon rates. Certain professional services revenues are based on fixed fee arrangements and revenues are recognized based on the proportional performance method. In some cases, the terms of our time and materials and fixed fee arrangements may require that we defer the recognition of revenue until contractual conditions are met. Data services and training revenues are generally recognized as the services are performed.

Multiple Element Arrangements

We apply the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2009-13, Multiple—Deliverable Revenue Arrangements, to allocate revenues based on relative best estimated selling price to each unit of accounting in multiple element arrangements, which generally include subscriptions and professional services. Best estimated selling price of each unit of accounting included in a multiple element arrangement is based upon management’s estimate of the selling price of deliverables when vendor specific objective evidence or third-party evidence of selling price is not available.

We enter into arrangements with multiple deliverables that generally include our subscription offerings and professional services. For these arrangements we must: (i) determine whether each deliverable has stand-alone value; (ii) determine the estimated selling price of each element using the selling price hierarchy of vendor-specific objective evidence (VSOE) of fair value, third party evidence (TPE) or best estimated selling price (BESP), as applicable; and (iii) allocate the total price among the various deliverables based on the relative selling price method.

In determining whether professional services and other revenues have stand-alone value, we consider the following factors for each consulting agreement: availability of the consulting services from other vendors, the nature of the consulting services and whether the professional services are required in order for the customer to use the subscription services. If stand-alone value cannot be established for a delivered item in a multiple-element arrangement, the delivered item is accounted for as a combined unit of accounting with the undelivered item(s).

We have established stand-alone value with respect to all of our offerings except professional services for the recently acquired Zinc Ahead business. As a result, we account for multiple element arrangements that include Zinc Ahead professional services as a combined unit of accounting and recognize the revenues from such professional services ratably over the term of the associated subscription services.

We have determined that we are not able to establish VSOE of fair value or TPE of selling price for any of our deliverables, and accordingly we use BESP for each deliverable in the arrangement. The objective of BESP is to estimate the price at which we would transact a sale of the service deliverables if the services were sold on a stand-alone basis. Revenue allocated to each deliverable is recognized when the basic revenue recognition criteria are met for each deliverable.

We determine BESP for our subscription services included in a multiple-element arrangement by considering multiple factors including, but not limited to, stated subscription renewal rates offered to the customer to renew the service and other major groupings such as customer type and geography.

BESP for professional services considers the discount of actual professional services sold compared to list price, the experience level of the individual performing the service and geography.

We allocate consideration proportionately based on established BESP and then recognize the allocated revenue over the respective delivery periods for each element.

Deferred Revenue

Deferred revenue includes amounts billed to customers for which the revenue recognition criteria have not been met. Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from our subscription services, and to a lesser extent, professional services and other revenues described above, and is recognized as the revenue recognition criteria are met. We generally invoice our customers in annual, quarterly or monthly installments for the subscription services, which are typically contracted for a term of one year or less. Accordingly, the deferred revenue balance does not generally represent the total contract value of a subscription arrangement. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue and the remaining portion is recorded as noncurrent, which is in the other long-term liabilities on the consolidated balance sheet.

Certain Risks and Concentrations of Credit Risk

Our revenues are derived from subscription services, professional services and other services delivered primarily to the pharmaceutical and life sciences industry. We operate in markets that are highly competitive and rapidly changing. Significant technological changes, shifting customer needs, the emergence of competitive products or services with new capabilities and other factors could negatively impact our operating results.

Our financial instruments that potentially subject us to concentration of credit risk consist primarily of cash and cash equivalents, short-term investments and trade accounts receivable. Our cash equivalents and short-term investments are held in safekeeping by large, credit-worthy financial institutions. We have established guidelines relative to credit ratings, diversification and maturities that seek to maintain safety and liquidity. Deposits in these financial institutions may exceed federally insured limits.

We do not require collateral from our customers and generally require payment within 30 to 60 days of billing. We periodically evaluate the collectibility of our accounts receivable and provide an allowance for doubtful accounts as necessary, based on historical experience. Historically, such losses have not been material.

The following customers individually exceeded 10% of total accounts receivable as of the dates shown:

	January 31,
	2016		2015
Customer 1		16%		11%
Customer 2		15	*
Customer 3	*			16

*	Does not exceed 10%.

In our fiscal years ended January 31, 2016, 2015 and 2014, our top 10 customers accounted for 50%, 54% and 56% of our total revenues, respectively. No single customer accounted for more than 10% of our total revenues for the fiscal years ended January 31, 2016, 2015 or 2014.

Cash Equivalents

We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. We classify certain restricted cash balances within other long-term assets on the accompanying balance sheets based upon the term of the remaining restrictions.

Short-term Investments

We classify short-term investments as available-for-sale at the time of purchase and reevaluate such classification as of each balance sheet date. All short-term investments are recorded at estimated fair value. Unrealized gains and losses for available-for-sale securities are included in accumulated other comprehensive income, a component of stockholders’ equity. We evaluate our investments to assess whether those with unrealized loss positions are other than temporarily impaired. We consider impairments to be other than temporary if they are related to deterioration in credit risk or if it is likely we will sell the securities before the recovery of their cost basis. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net, in the consolidated statements of comprehensive income. Interest, amortization of premiums, and accretion of discount on all short-term investments classified as available for sale are also included as a component of other income (expense), net, in the condensed consolidated statements of comprehensive income.

We may sell our short-term investments at any time, without significant penalty, for use in current operations or for other purposes, even if they have not yet reached maturity. As a result, we classify our investments, including securities with maturities beyond 12 months as current assets in the accompanying consolidated balance sheets.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest. We establish an allowance for doubtful accounts for estimated losses expected in our accounts receivable portfolio. In establishing the required allowance, we use the specific-identification method, and management considers historical losses adjusted to take into account current market conditions and the customers’ financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. We review our allowance for doubtful accounts periodically. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Activity related to our allowance for doubtful accounts was as follows (in thousands):

	Fiscal Year Ended January 31,
	2016			2015			2014
Balance at beginning of period	$	413		$	305		$	305
Add: charges (credits) to costs and expenses		201			227			(35	)
Less: recoveries (write-offs)		(72	)		(119	)		35
Balance at end of period	$	542		$	413		$	305

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated on the straight-line method over the estimated useful lives of the assets and commences once the asset is placed in service or ready for its intended use. Construction in progress is related to the construction or development of property (including land) and equipment that have not yet been placed in service for our intended use. The estimated useful lives by asset classification are generally as follows:

Asset Classification		Estimated Useful Life
Land		Not depreciated
Building		30 years
Land and building improvements		Shorter of remaining life of building or estimated useful life
Equipment and computers		3 years
Furniture and fixtures		5 years
Leasehold improvements		Shorter of remaining life of the lease term or estimated useful life

Upon sale or retirement of an asset, the cost and related accumulated depreciation are removed from the general ledger and any related gains or losses are reflected in operating expenses. Repairs and maintenance are charged to our statement of comprehensive income as incurred.

Internal-Use Software

We capitalize certain costs incurred for the development of computer software for internal use. These costs generally relate to the development of our customer relationship management, content and information management and customer master solutions. We capitalize these costs during the development of the project, when it is determined that it is probable that the project will be completed, and the software will be used as intended. Costs related to preliminary project activities, post-implementation activities, training and maintenance are expensed as incurred. Internal-use software is amortized on a straight-line basis over its estimated useful life, generally three years, and the amortization expense is recorded as a component of cost of subscription services. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. We exercise judgment in determining the point at which various projects may be capitalized, in assessing the ongoing value of the capitalized costs and in determining the estimated useful lives over which the costs are amortized. To the extent that we change the manner in which we develop and test new features and functionalities related to our solutions, assess the ongoing value of capitalized assets or determine the estimated useful lives over which the costs are amortized, the amount of internal-use software development costs we capitalize and amortize could change in future periods.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with business combinations accounted for using the acquisition method of accounting. Goodwill is not amortized, but instead goodwill is required to be tested for impairment annually and under certain circumstances. We perform such testing of goodwill in the fourth quarter of each year, or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

If we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then conduct a two-step test for impairment of goodwill. The first step of the test for goodwill impairment compares the fair value of the applicable reporting unit with its carrying value. If the fair value of a reporting unit is less than the reporting unit’s carrying value, we will perform the second step of the test for impairment of goodwill. During the second step of the test for impairment of goodwill, we will compare the implied fair value of the reporting unit’s goodwill with the carrying value of that goodwill. If the carrying value of the goodwill exceeds the calculated implied fair value, the excess amount will be recognized as an impairment loss. We have one reporting unit and evaluate goodwill for impairment at the entity level. We completed our annual impairment test in our fourth quarter of fiscal 2016, which did not result in any impairment of the goodwill balance.

All other intangible assets associated with purchased intangibles, consisting of existing technology, databases, customer contracts and relationships, software, and brand are stated at cost less accumulated amortization and are amortized on a straight-line basis over their estimated remaining economic lives. Amortization expense related to existing technology, databases and software is included in cost of subscription services. Amortization expense related to customer contracts and relationships and brand are included in sales and marketing expense.

Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, we first compare undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. There were no impairment charges recognized during fiscal 2016, 2015 and 2014.

Business Combinations

We use our best estimates and assumptions to accurately assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Our estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions and tax-related valuation allowances are initially established in connection with a business combination as of the acquisition date. We continue to collect information and reevaluate these estimates and assumptions quarterly and record any adjustments to our preliminary estimates to goodwill provided that we are within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of comprehensive income.

Stock-based Compensation

We recognize compensation expense for all stock-based awards, including stock options and restricted stock units (RSUs), based on the estimate of fair value of the award at the grant date. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and a single option award approach. This model requires that at the date of grant we determine the fair value of the underlying common stock, the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The compensation expense recorded is based on awards ultimately expected to vest and therefore is reduced by estimated forfeitures. Forfeitures are estimated at the time of grant based on an analysis of our actual historical forfeitures, and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The compensation expense, net of estimated forfeitures, is recognized using a straight-line basis over the requisite service periods of the awards, which is generally four to nine years. We estimate a forfeiture rate to calculate the stock-based compensation expense for our awards.

The fair value of each stock-based payment award and stock purchase right granted under the 2013 Employee Stock Purchase Plan (ESPP) was estimated on the date of grant using the Black-Scholes option pricing model. We recognized stock-based compensation expenses related to our ESPP on a straight-line basis over the offering period, which was seven months.

The determination of the grant date fair value of stock based payment awards using an option-pricing model are affected by assumptions regarding a number of other complex and subjective variables, which include our expected stock price volatility over the expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends.

Cost of Revenues

Cost of subscription services and professional services and other revenues are expensed as incurred. Cost of subscription services revenues primarily consists of expenses related to third-party data centers, personnel related costs associated with hosting our subscription services and providing support, including our data stewards, operating lease expense associated with computer equipment and software and allocated overhead, amortization expense associated with capitalized internal-use software related to our subscription services and amortization expense associated with purchased intangibles related to our subscription services. Cost of subscription services revenues for Veeva CRM and certain of our multichannel customer relationship management applications also include fees paid to salesforce.com, inc. for our use of the Salesforce1 Platform and the associated hosting infrastructure and data center operations that are provided by salesforce.com.

Cost of professional services and other revenues primarily consists of employee-related expenses associated with providing these services, including salaries, benefits and stock-based compensation expense, the cost of third-party subcontractor costs, travel costs and allocated overhead.

Sales Commissions

Sales commissions paid for subscriptions are recorded as a component of sales and marketing expenses when earned by our sales team. Commissions are typically earned upon booking of a customer contract. Sales commission expense was $16.4 million, $13.2 million and $11.8 million for the fiscal years ended January 31, 2016, 2015 and 2014, respectively.

Advertising Expenses

Advertising is expensed as incurred. Advertising expense was $0.2 million, $0.1 million and $0.2 million for the fiscal years ended January 31, 2016, 2015 and 2014, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We regularly assess the realizability of our deferred tax assets and establish a valuation allowance if it is more-likely-than-not that some or all of our deferred tax assets will not be realized. We evaluate and weigh all available positive and negative evidence such as historic results, future reversals of existing deferred tax liabilities, projected future taxable income, as well as prudent and feasible tax-planning strategies. Generally, more weight is given to objectively verifiable evidence, such as the cumulative loss in recent years.

We establish liabilities or reduce assets for uncertain tax positions when we believe certain tax positions are not more likely than not of being sustained if challenged. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining whether the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If we determine that a tax position will more likely than not be sustained on audit, the second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement with the tax authority. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately forecast actual outcomes. Determining whether an uncertain tax position is effectively settled requires judgment. Such a change in status or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.

We recognize interest accrued and penalties related to unrecognized tax benefits in our income tax expense.

Other Comprehensive Income

Accumulated other comprehensive income is reported as a component of stockholders’ equity and include unrealized gains and losses on marketable securities that are available-for-sale and foreign currency translation adjustment.

Foreign Currency Exchange

The functional currency for Brazil, China, India, Japan, Korea and the Zinc subsidiaries in the United Kingdom is their local currency and for all other foreign subsidiaries their functional currency is the U.S. dollar. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars for those entities that do not have U.S. dollars as their functional currency are recorded as part of a separate component of the consolidated statements of comprehensive income. Foreign currency transaction gains and losses are included in the consolidated statements of operations for the period. All assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average exchange rate during the period. Equity transactions are translated using historical exchange rates.

Warranties and Indemnification

Our cloud applications are generally warranted to perform materially in accordance with our standard services description documentation. Additionally, our contracts generally include provisions for indemnifying customers against liabilities if our solutions infringe a third party’s intellectual property rights, and we may also incur liabilities if we breach the security and/or confidentiality obligations in our contracts. To date, we have not incurred any material costs, and we have not accrued any liabilities in the accompanying consolidated financial statements, as a result of these obligations. We also entered into service-level agreements with our customers that specify required levels of application uptime and permit customers to receive credits or to terminate their agreements and receive a refund of prepaid amounts related to unused subscription services in the event that we fail to meet required performance levels. To date, we have not experienced any significant failures to meet defined levels of performance and, as a result, we have not accrued any liabilities related to these agreements in the consolidated financial statements.

Recent Accounting Pronouncements

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “Leases”. ASU 2016-02 requires that lease arrangements longer than twelve months result in an entity recognizing an asset and liability. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. We have not evaluated the impact of the updated guidance on our consolidated financial statements.

Financial Instruments

In January 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-1, “Financial Instruments.” This guidance outlines the classification and measurement of financial instruments. The requirement to disclose the methods and significant assumptions used to estimate fair value is removed. In addition, financial assets and financial liabilities are to be presented separately in the notes to the financial statements, grouped by measurement category and form of financial asset. This standard will be effective for our fiscal year beginning in February 1, 2017. Early adoption is permitted. We do not expect this standard to have a material impact on our financial statements.

Deferred Taxes

In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes.” This guidance simplifies the presentation of deferred income taxes, which requires that deferred income tax liabilities and assets be presented as a net non-current deferred tax asset or liability by jurisdiction on the balance sheet. The current requirement that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is unchanged. The ASU is effective for periods beginning after December 15, 2016, however earlier adoption is permitted for all entities for any interim or annual financial statements that have not been issued. The Company early adopted the standard in the fourth quarter of 2016 on a prospective basis and, accordingly, reclassified $4.1 million of current deferred tax assets from “Deferred income taxes” to “Deferred income taxes, noncurrent” in the consolidated balance sheet at January 31, 2016. The prior year balances were not retrospectively adjusted.

Business Combinations

In September 2015, the FASB issued ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments.” This guidance requires the acquirer to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings for changes in depreciation or amortization, or other income effects (if any) as a result of the change to the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, must be recorded in the reporting period in which the adjustment amounts are determined rather than retrospectively. This standard will be applied prospectively to adjustments to provisional amounts that occur after the effective date. This standard will be effective for our fiscal year beginning in February 1, 2016. Early adoption is permitted. We do not expect this standard to have a material impact on our financial statements.

Cloud Computing Arrangements

In April 2015, the FASB issued ASU 2015-05, “Customer's Accounting for Fees Paid in a Cloud Computing Arrangement.” This guidance is intended to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement, primarily to determine whether the arrangement includes a sale or license of software. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. This standard will be adopted on a prospective basis for our fiscal year beginning February 1, 2016. Early adoption is permitted. We do not expect this standard to have a material impact on our financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” This guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model requires revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 supersedes the existing revenue recognition guidance in “Revenue Recognition (Topic 605)”. This update should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” This Update defers the effective date of ASU 2014-09 for all entities by one year, although companies still have the option to begin applying the new guidance as of the original effective date. In accordance with the deferral, this guidance will be effective for our fiscal year beginning February 1, 2018. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures and have not selected a transition method yet.

Net Income per Share Attributable to Common Stockholders

We compute net income per share of Class A and Class B common stock using the two-class method required for participating securities. Prior to the date of our IPO in October 2013, we considered all series of our convertible preferred stock to be participating securities due to their non-cumulative dividend rights. Immediately prior to the completion of our IPO, all outstanding shares of convertible preferred stock converted to Class B common stock. Additionally, we consider unvested shares issued upon the early exercise of options to be participating securities as the holders of these shares have a non-forfeitable right to dividends in the event of our declaration of a dividend for common shares.

Under the two-class method, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income, less (i) current period convertible preferred stock non-cumulative dividends and (ii) earnings attributable to participating securities.

The net income per share attributable to common stockholders is allocated based on the contractual participation rights of the Class A common stock and Class B common stock as if the income for the year has been distributed. As the liquidation and dividend rights are identical, the net income attributable to common stockholders is allocated on a proportionate basis.

Basic net income per share of common stock is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. All participating securities are excluded from the basic weighted-average shares of common stock outstanding. Unvested shares of common stock resulting from the early exercises of stock options are excluded from the calculation of the weighted-average shares of common stock until they vest as they are subject to repurchase until they are vested.

Diluted net income per share attributable to common stockholders is computed by dividing net income attributable to common stockholders by the weighted-average shares outstanding, including potentially dilutive shares of common stock assuming the dilutive effect of potential shares of common stock for the period determined using the treasury stock method.

Undistributed net income for a given period is apportioned to participating securities based on the weighted-average shares of each class of common stock outstanding during the applicable period as a percentage of the total weighted-average shares outstanding during the same period.

For purposes of the diluted net income per share attributable to common stockholders calculation, unvested shares of common stock resulting from the early exercises of stock options and unvested options to purchase common stock are considered to be potentially dilutive shares of common stock. In addition, the computation of the fully diluted net income per share of Class A common stock assumes the conversion from Class B common stock, while the fully diluted net income per share of Class B common stock does not assume the conversion of those shares.
