2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial reporting and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted pursuant to those rules or regulations. The interim financial statements are unaudited, but reflect all adjustments which are, in the opinion of management, considered necessary for a fair presentation. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes included in our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission on March 11, 2011. The results of operations for the interim periods are not necessarily indicative of results to be expected in future periods.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

On an ongoing basis, we evaluate our estimates, including those related to the accounts receivable allowance, sales return allowance, warranty reserve, reserve for excess and obsolete inventory, useful lives of tangible and intangible long-lived assets, goodwill and intangible asset impairment, income taxes, and our assumptions used for the purpose of determining stock-based compensation, among other things. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented.

Investments

We determine the appropriate classification of our investments at the time of purchase and reevaluate such classification as of each balance sheet date. Our investments are comprised of money market funds, corporate debt investments, commercial paper, government-sponsored enterprise securities, government securities and certificates of deposit. These investments have been classified as available-for-sale. Available-for-sale investments are stated at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income. Amortization is included in interest and investment income. Interest on securities classified as available-for-sale is also included in interest and investment income.

 

7


Table of Contents

We evaluate our investments on a regular basis to determine whether an other-than-temporary impairment in fair value has occurred. If an investment is in an unrealized loss position and we have the intent to sell the investment, or it is more likely than not that we will have to sell the investment before recovery of its amortized cost basis, the decline in value is deemed to be other-than-temporary and is charged against earnings for the period. For investments that we do not intend to sell or it is more likely than not that we will not have to sell the investment, but we expect that we will not fully recover the amortized cost basis, the credit component of the other-than-temporary impairment is charged against earnings for the applicable period and the non-credit component of the other-than-temporary impairment is recognized in other comprehensive income on our consolidated statement of stockholders’ equity and comprehensive income (loss). Unrealized losses entirely caused by non-credit related factors related to investments for which we expect to fully recover the amortized cost basis are recorded in accumulated other comprehensive income.

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, investments, accounts receivable, cash surrender value on our split-dollar life insurance policy, accounts payable and deferred revenue. The fair value of these financial instruments approximates their carrying amounts reported in the consolidated balance sheets. The fair value of available-for-sale investments is determined using quoted market prices for those investments.

Allowance for Doubtful Accounts and Sales Return Allowance

We make estimates regarding the collectability of our accounts receivable. When we evaluate the adequacy of our allowance for doubtful accounts, we consider multiple factors, including historical write-off experience, the need for specific customer reserves, the aging of our receivables, customer creditworthiness and changes in customer payment cycles. Historically, our allowance for doubtful accounts has been adequate based on actual results. If any of the factors used to calculate the allowance for doubtful accounts change or if the allowance does not reflect our actual ability to collect outstanding receivables, additional provisions for doubtful accounts may be needed, and our future results of operations could be materially affected. As of September 30, 2011 and December 31, 2010, the allowance for doubtful accounts was $0.3 million and $0.4 million, respectively.

We also use our judgment to make estimates regarding potential future product returns related to reported product revenue in each period. We analyze factors such as our historical return experience, current product sales volumes, and changes in product warranty claims when evaluating the adequacy of the sales returns allowance. If any of the factors used to calculate the sales return allowance were to change, we may experience a material difference in the amount and timing of our product revenue for any given period. As of September 30, 2011 and December 31, 2010, the sales return allowance was $0.7 million for each period.

Inventory

Inventory consists of hardware and related component parts and is stated at the lower of cost on a first-in, first-out basis, or market, except for evaluation and advance replacement units which are stated at the lower of cost, on a specific identification basis, or market. Evaluation units are used for customer testing and evaluation and are predominantly located at the customers’ premises. Advance replacement units, which include fully functioning appliances and spare parts, are used to provide replacement units under technical support arrangements if a customer’s unit is not functioning properly. We make estimates of forecasted demand for our products, and inventory that is obsolete or in excess of our estimated demand is written down to its estimated net realizable value based on historical usage, expected demand, the timing of new product introductions and age. It is reasonably possible that our estimate of future demand for our products could change in the near term and result in additional inventory write-downs, which would negatively impact our future results of operations.

Inventory write-downs, primarily related to evaluation units and excess and obsolete inventory as a result of the introduction of new products, are recorded as a component of cost of revenues and amounted to approximately $0.3 million and $1.7 million for the three months and nine months ended September 30, 2011, respectively. Inventory write-downs, primarily related to evaluation units and excess and obsolete inventory, amounted to approximately $0.5 million and $0.8 million for the three months and nine months ended September 30, 2010, respectively.

Business Combinations

We recognize all of the assets acquired, liabilities assumed and contingent consideration at their fair value on the acquisition date. The purchase price allocation process requires management to make significant estimates and assumptions, especially at the acquisition date with respect to intangible assets acquired, estimated contingent consideration payments and pre-acquisition contingencies assumed. Unanticipated events and circumstances may occur which may affect the accuracy or validity of such assumptions, estimates or actual results. Additionally, any change in the fair value of the acquisition-related contingent consideration subsequent to the acquisition date, including changes from events after the acquisition date, will be recognized in earnings in the period of the estimated fair value change. All subsequent changes to a valuation allowance or uncertain tax position relating to the acquired company that occur within the measurement period and are based on facts and circumstances that existed at the acquisition date are recognized as an adjustment to goodwill. All other changes in a valuation allowance or uncertain tax positions are recognized as a reduction or increase to income tax expense.

Acquisition-related transaction costs, including legal and accounting fees and other external costs directly related to the acquisition are recognized separately from the acquisition and expensed as incurred in general and administrative expenses in the consolidated statements of operations.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets acquired. We test goodwill resulting from acquisitions for impairment annually on October 1, or whenever events or changes in circumstances indicate a potential impairment. If it is determined that an impairment has occurred, we will record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. Although we believe goodwill is appropriately stated in the consolidated financial statements, changes in strategy or market conditions could significantly impact these judgments and require an adjustment to the recorded balance.

Intangible assets that are not considered to have an indefinite life are amortized over their useful lives on a straight-line basis. On a periodic basis, we evaluate the estimated remaining useful life of acquired intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. The carrying amounts of these assets are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable.

Other Assets

Other assets primarily consist of a prepaid long-term contract for a third-party to provide maintenance and support services for certain product offerings and will be amortized through 2015 based on its expected usage. The amortization will be recorded as a component of cost of revenues.

Revenue Recognition

We derive revenue from arrangements that include hardware products with embedded software, software licenses and royalties, technical support, and professional services. Revenue from products in the accompanying consolidated statements of operations consists primarily of sales of hardware appliances containing software, but also includes fees and royalties for the license of our technology in a software-only format and subscriptions to receive rules released by the Vulnerability Research Team, or VRT, that are used to update the appliances for current exploits and vulnerabilities. Technical support, which generally has a contractual term of 12 months, includes telephone and web-based support, software updates, and rights to software upgrades on a when-and-if-available basis. Professional services include training and consulting.

For each arrangement, we recognize revenue when: (a) persuasive evidence of an arrangement exists (e.g., a signed contract); (b) delivery of the product has occurred and there are no remaining obligations or substantive customer acceptance provisions; (c) the fee is fixed or determinable; and (d) collection of the fee is deemed probable.

For sales through resellers and distributors, we recognize revenue upon the shipment of the product only if those resellers and distributors provide us, at the time of placing their order, with the identity of the end-user customer to whom the product has been sold. To the extent that a reseller or distributor requests an inventory or stock of products, we defer revenue on that product until we receive notification that it has been sold through to an identified end-user.

All amounts billed or received in excess of the revenue recognized are included in deferred revenue. In addition, we defer all direct costs associated with revenue that has been deferred. These amounts are included in either prepaid expenses and other current assets or inventory in the accompanying balance sheets, depending on the nature of the costs and the reason for the deferral.

In October 2009, the Financial Accounting Standards Board, or 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:

 

  (i) 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;

 

  (ii) require an entity to allocate arrangement consideration to each element based on a selling price hierarchy, where the selling price for an element is based on vendor-specific objective evidence, or VSOE, if available; third-party evidence, or TPE, if available and VSOE is not available; or the best estimate of selling price, or BESP, if neither VSOE or TPE is available; and

 

  (iii) eliminate the use of the residual method and require an entity to allocate arrangement consideration based on the relative selling price of each element within the arrangement.

We adopted this accounting guidance on January 1, 2011 on a prospective basis for applicable transactions originating or materially modified after December 31, 2010.

The majority of our products are hardware appliances containing software components that operate together to provide the essential functionality of the product. Therefore, our hardware appliances are considered non-software deliverables and are no longer accounted for under the industry-specific software revenue recognition guidance.

Our product revenue also includes revenue from the sale of stand-alone software products. Stand-alone software may operate on our hardware appliance, but is not considered essential to the functionality of the hardware. Stand-alone software sales generally include a perpetual license to our software. Stand-alone software sales continue to be subject to the industry-specific software revenue recognition guidance.

For stand-alone software sales after December 31, 2010 and for all transactions entered into prior to the first quarter of 2011, we recognize revenue based on software revenue recognition guidance. Under the software revenue recognition guidance, we allocate the total arrangement fee among each deliverable based on the fair value of each of the deliverables, determined based on VSOE. If VSOE of fair value does not exist for each of the deliverables, all revenue from the arrangement is deferred

Table of Contents

until the earlier of the point at which sufficient VSOE of fair value can be determined for any undelivered elements or all elements of the arrangement have been delivered. If the only undelivered elements are elements for which we currently have VSOE of fair value, we recognize revenue for the delivered elements based on the residual method. When VSOE of fair value does not exist for undelivered elements such as maintenance and support, the entire arrangement fee is recognized ratably over the performance period.

For all transactions originating or materially modified after December 31, 2010, we recognize revenue in accordance with the amended accounting guidance. Certain arrangements with multiple deliverables may continue to have stand-alone software deliverables that are subject to the existing software revenue recognition guidance along with non-software deliverables that are subject to the amended revenue accounting guidance. The revenue for these multiple deliverable arrangements is allocated to the stand-alone software deliverables as a group and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the fair value hierarchy in the amended revenue accounting guidance.

We have established VSOE of fair value for substantially all of our technical support based upon actual renewals of each type of technical support that is offered and for each customer class. Technical support and technical support renewals are currently priced based on a percentage of the list price of the respective product or software and historically have not varied from a narrow range of values in the substantial majority of our arrangements. Revenue related to technical support is deferred and recognized ratably over the contractual period of the technical support arrangement, which is generally 12 months. The VSOE of fair value of our other services is based on the price for these same services when they are sold separately. Revenue for professional services that are sold either on a stand-alone basis or included in multiple element arrangements is deferred and recognized as the services are performed.

For our non-software deliverables we allocate the arrangement consideration based on the relative selling price of the deliverables. For our hardware appliances we use BESP as our selling price. For our support and services, we generally use VSOE as our selling price.

We are typically not able to determine TPE for our products or services. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis.

When we are unable to establish the selling price of our non-software deliverables using VSOE or TPE, we use BESP in our allocation of arrangement consideration. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We determine BESP for a product or service by considering multiple factors including, but not limited to, gross margin objectives, pricing practices, customer classes and geographies and distribution channels.

For certain arrangements we will be able to account for more transaction consideration upon delivery than allowed under the prior guidance, primarily due to more deliverables being accounted for as separate units of accounting and the elimination of the use of the residual method and a requirement to allocate arrangement consideration using a selling price hierarchy.

An estimate of the revenue that would have been reported if we had applied the new guidance for multiple deliverable arrangements for non-software deliverables for the three months ended September 30, 2010 is $36.6 million compared to the $36.2 million of revenue recognized under the industry specific software revenue recognition rules and for the nine months ended September 30, 2010 is $93.7 million compared to the $92.6 million of revenue recognized under the industry specific software revenue recognition rules.

We record taxes collected on revenue-producing activities on a net basis.

For the three months ended September 30, 2011, two customers, one a reseller of our products and the other a distributor of our products to the U.S. government, accounted for 10% and 34%, respectively, of total revenue. For the nine months ended September 30, 2011, two customers, one a reseller of our products and the other a distributor of our products to the U.S. government, accounted for 11% and 21%, respectively, of total revenue. For the three months ended September 30, 2010, one customer, a distributor of our products to the U.S. government, accounted for 29% of total revenue. For the nine months ended September 30, 2010, two customers, one a reseller and the other a distributor of our products to the U.S. government, accounted for 10% and 18%, respectively, of total revenue.

Table of Contents

As of September 30, 2011, two customers, one a distributor of our products to the U.S. government and the other a reseller of our products, accounted for 40% and 10% of our accounts receivable, respectively. As of December 31, 2010, two customers, a reseller of our products and a distributor of our products to the U.S. government, accounted for 14% and 10%, respectively, of our accounts receivable.

Warranty

Under our standard warranty arrangement, we warrant that our software will perform in accordance with its documentation for a period of 90 days from the date of shipment. Similarly, we warrant that the hardware will perform in accordance with its documentation for a period of one year from date of shipment. We further agree to repair or replace software or products that do not conform to those warranties. The one year warranty on hardware coincides with the hardware warranty that we obtain from the manufacturer. We estimate the additional costs, if any, that may be incurred under our warranties outside of the warranties supplied by the manufacturer and record a liability at the time product revenue is recognized. Factors that affect our warranty liability include the number of units sold, historical and anticipated rates of warranty claims and the estimated cost per claim. We periodically assess the adequacy of our recorded warranty liability and adjust the amounts as necessary. While actual warranty costs have historically been within our cost estimations, it is possible that warranty rates could increase in the future due to new hardware introductions, general hardware component cost and availability, among other factors.

Income Taxes

Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities and for tax carryforwards at enacted statutory tax rates in effect for the years in which the differences are expected to reverse.

We assess the realizability of our deferred tax assets, which primarily consist of net operating loss, or NOL, carryforwards, and temporary differences associated with stock-based compensation expense, deferred revenue and research and experimentation tax credit carryforwards. In assessing the realizability of these deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be realized. In assessing the need for a valuation allowance, we consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies.

With respect to foreign earnings, it is our policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. Any excess tax benefit, above amounts previously recorded for stock-based compensation expense, from the exercise of stock options is recorded in additional paid-in-capital in the consolidated balance sheets to the extent that cash taxes payable are reduced.

Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, we make certain estimates and assumptions, in (i) calculating our provision for income taxes, deferred tax assets and deferred tax liabilities, (ii) determining any valuation allowance recorded against deferred tax assets and (iii) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. Our estimates and assumptions may differ significantly from tax benefits ultimately realized.

Stock-Based Compensation

Stock-based awards granted include stock options, restricted stock awards and restricted stock units under our 2007 Stock Incentive Plan, or 2007 Plan, and stock purchased under our Amended and Restated 2007 Employee Stock Purchase Plan, or ESPP. Stock-based compensation expense is measured at the grant date, based on the fair value of the awards, and is recognized as expense ratably over the requisite service period, net of estimated forfeitures.

We use the Black-Scholes option pricing model for estimating the fair value of stock options granted under the 2007 Plan and for employee stock purchases under the ESPP. The use of option valuation models requires the input of highly subjective assumptions, including the expected term and the expected stock price volatility. Additionally, the recognition of expense requires the estimation of the number of options that will ultimately vest and the number of options that will ultimately be forfeited.

Net Income Per Share

Basic net income per share is computed on the basis of the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and restricted stock units.

Recent Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board, or FASB, issued revised guidance to simplify how entities test goodwill for impairment. Entities are allowed to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If a greater than 50 percent likelihood exists that the fair value is less than the carrying amount then a two-step goodwill impairment test must be performed. This accounting guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We do not believe this guidance will have a significant impact on our consolidated financial statements.

In June 2011, the FASB issued guidance that requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of equity. This guidance is effective for fiscal years beginning after December 15, 2011. We do not believe this guidance will have a significant impact on our consolidated financial statements.

 

3. Acquisition

On December 30, 2010, we acquired all the outstanding securities of Immunet Corporation, or Immunet, a leading provider of advanced cloud-based anti-malware technologies. This acquisition expands our security solutions portfolio, adding an advanced cloud platform for end-point protection. The acquisition price of $21 million consists of $14.9 million in cash payable at closing, of which $7.7 million was paid in 2010 and $7.2 million was paid in the first quarter of 2011. An additional $2.1 million will be paid on the twelve month anniversary of the acquisition date subject to working capital adjustments. The remaining $4.0 million of the acquisition price is contingent consideration and is now expected to be paid within 12 to 15 months of the acquisition date to Immunet common shareholders upon achievement of product delivery milestones related to the enterprise version of Immunet’s product.

Under the acquisition method of accounting, the total estimated purchase price was allocated to Immunet’s net tangible assets and liabilities and intangible assets based on their estimated fair values as of December 30, 2010. We recorded the excess of the purchase price over the net tangible assets and liabilities and intangible assets as goodwill. At the acquisition date, the fair value of consideration transferred and contingent consideration was $20.4 million. This was preliminarily allocated to tangible assets of $0.3 million, liabilities of $0.2 million, net deferred tax liabilities of $1.6 million, identifiable intangible assets of $6.8 million and goodwill of $15.1 million. The goodwill represents factors including expected synergies from combining operations and is not deductible for tax purposes.

Prior to the end of the measurement period for finalizing the purchase price allocation, if information becomes available that would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocation and prior period financial statements will be retroactively adjusted, if material.

As of September 30, 2011, the unrealized holding loss, net of tax, on available-for-sale securities included in accumulated other comprehensive income (loss) totaled $0.1 million. We have evaluated our investments and have determined there were no other-than-temporary impairments as of September 30, 2011. There are 33 corporate debt investments and 8 government-sponsored enterprise investments with unrealized losses that have existed for less than one year. The unrealized losses related to these investments are entirely caused by non-credit related factors. We do not have the intent to sell these securities and we expect to fully recover the amortized cost basis of these investments.

 

5. Goodwill and Intangible Assets

Goodwill represents the excess of the consideration transferred over the fair values assigned to the assets acquired and liabilities assumed. On December 30, 2010, in connection with the acquisition of Immunet, we recorded goodwill of $15.1 million, which was assigned to our one reporting unit.

Also in connection with the acquisition of Immunet, we acquired certain intangible assets of $6.8 million. We allocated $1.8 million to in-process research and development with an indefinite life and $5.0 million to acquired technology with an estimated useful life of 5 years. The in-process research and development will be considered indefinite lived until completion or abandonment of the associated research and development. While it is considered indefinite lived it will be tested for impairment on an annual basis. Once the associated research and development is complete, we will determine the useful life of the assets and amortize the in-process research and development over that time period on a straight-line basis unless another method is determined to be more appropriate.

Amortization expense for the three months and nine months ended September 30, 2011 was $0.3 million and $0.8 million, respectively, and is recorded as a component of product cost of revenue. There was no amortization expense for the three months and nine months ended September 30, 2010.

 

6. Income Taxes

Our effective tax rate for the three months ended September 30, 2011 is an expense of 42%, compared to an expense of 17% in the prior-year period. Our effective tax rate for the nine months ended September 30, 2011 is a benefit of 757%, compared to a benefit of 70% in the prior-year period. Our benefit from income taxes for the nine months ended September 30, 2011 is based on an estimated annual effective tax rate for 2011 of 38.1% and a discrete tax benefit of $2.0 million from research and experimentation tax credits for the years 2003 through 2010 recorded in the first quarter of 2011. Our 2011 estimated annual effective tax rate includes the U.S. federal statutory rate of 34%, state income taxes and foreign income taxed at different rates, partially offset by the impact of research and experimentation tax credits projected for 2011. The net benefit recorded for the nine months ended September 30, 2010 was primarily due to a tax benefit of $7.6 million recorded upon our decision in the second quarter of 2010 to release the valuation allowance recorded against our deferred tax assets in the U.S. Virtually all of our income before income tax expense is considered to be domestic income.

In the first quarter of 2011, we established a liability of $0.3 million for uncertain tax positions recognized in the current year. The amount of the reserve for uncertain tax benefits that, if released, would impact the effective tax rate was $0.3 million as of September 30, 2011.

 

7. Stock-Based Compensation

In March 2007, our Board of Directors and stockholders approved the Sourcefire, Inc. 2007 Stock Incentive Plan, or 2007 Plan, which provides for the granting of equity-based awards, including stock options, restricted or unrestricted stock awards, and stock appreciation rights to employees, officers, directors, and other individuals as determined by the Board of Directors. As of December 31, 2010, we had reserved an aggregate of 6,249,532 shares of common stock for issuance under the 2007 Plan. On January 1, 2011, under the terms of the 2007 Plan, the aggregate number of shares reserved for issuance under the 2007 Plan was increased by an amount equal to 4% of our outstanding common stock as of December 31, 2010, or 1,125,442 shares. Therefore, as of September 30, 2011, we have reserved an aggregate of 7,374,974 shares of common stock for issuance under the 2007 Plan. Prior to adoption of the 2007 Plan, we granted stock options and restricted stock awards under the Sourcefire, Inc. 2002 Stock Incentive Plan, or 2002 Plan.

The 2002 Plan and the 2007 Plan are administered by the Compensation Committee of our Board of Directors. The vesting period for awards under the plans is generally between three and five years. Options granted prior to March 2010 have a maximum term of ten years, and options granted beginning March 2010 have a maximum term of seven years. The exercise price of stock option awards is equal to at least the fair value of the common stock on the date of grant. The fair value of our common stock is determined by reference to the closing trading price of the common stock on the NASDAQ Global Select Market on the date of grant.

Valuation of Stock-Based Compensation

We use the Black-Scholes option pricing model for estimating the fair value of stock options granted and for employee stock purchases under the ESPP. The use of option valuation models requires the input of highly subjective assumptions, including the expected term and the expected stock price volatility. Additionally, the recognition of expense requires the estimation of the number of options that will ultimately vest and the number of options that will ultimately be forfeited. The fair value of stock-based awards is recognized as expense ratably over the requisite service period, net of estimated forfeitures. We rely on historical experience of employee turnover to estimate our expected forfeitures.

The following are the weighted-average assumptions and fair values used in the Black-Scholes option valuation of stock options granted under the 2002 Plan and the 2007 Plan and ESPP grants.

Weighted-average fair value at grant date

Average risk-free interest rate — This is the average U.S. Treasury rate, with a term that most closely resembles the expected life of the option, as of the grant date.

Expected dividend yield — We use an expected dividend yield of zero, as we have never declared or paid dividends on our common stock and do not anticipate paying dividends in the foreseeable future.

Expected life — This is the period of time that the stock options granted under our equity incentive plans and ESPP grants are expected to remain outstanding.

As we do not yet have sufficient historical experience for determining the expected term of the stock options granted, we have based our expected term on the simplified method. This estimate is derived from the average midpoint between the weighted-average vesting period and the contractual term. In future periods, we expect to begin to incorporate our own data in estimating the expected life as we develop appropriate historical experience of employee exercise and post-vesting termination behavior considered in relation to the contractual life of the option. For ESPP grants, the expected life is the plan period.

Expected volatility — Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period.

For stock options granted, since our historical stock data from our IPO in March 2007 is less than the expected life of the stock options, we have used a blended volatility to estimate expected volatility. The blended volatility includes a weighting of our historical volatility from the date of our IPO to the respective grant date and an average of our peer group historical volatility consistent with the expected life of the option. Our peer group historical volatility includes the historical volatility of companies that are similar in revenue size, are in the same industry or are competitors. We expect to continue to use a larger proportion of our historical volatility in future periods as we develop additional historical experience of our own stock price fluctuations considered in relation to the expected life of the option.

For ESPP grants, we use our historical volatility since we have historical data available since our IPO, which is consistent with the expected life.

If we had made different assumptions about the stock price volatility rates, expected life, expected forfeitures and other assumptions, the related stock-based compensation expense and net income could have been significantly different.

The aggregate intrinsic value of all options exercised during the nine months ended September 30, 2011 and 2010 was $6.6 million and $12.4 million, respectively.

Outstanding stock option awards are generally subject to service-based vesting; however, in some instances, awards contain provisions for acceleration of vesting upon performance measures, change in control and in certain other circumstances. On a quarterly basis, we evaluate the probability of achieving performance measures and adjust compensation expense accordingly. Based on the estimated grant date fair value of employee stock options granted, we recognized compensation expense of $1.5 million and $1.0 million for the three months ended September 30, 2011 and 2010, respectively, and $4.2 million and $2.9 million for the nine months ended September 30, 2011 and 2010. The grant date aggregate fair value of options, net of estimated forfeitures, not yet recognized as expense as of September 30, 2011 was $13.5 million, which is expected to be recognized over a weighted average period of 2.84 years.

Restricted stock awards are generally subject to service-based vesting; however, in some instances, awards contain provisions for acceleration of vesting upon performance measures, change in control and in certain other circumstances. Holders of restricted stock awards have the right to vote such shares and receive dividends. The restricted stock awards are considered issued and outstanding at the date the award is granted. On a quarterly basis, we evaluate the probability of achieving performance measures and adjust compensation expense accordingly. The compensation expense is recognized ratably over the estimated vesting period. The vesting restrictions for outstanding restricted stock awards generally lapse over a period of 36 to 60 months.

The fair value of the unvested restricted stock awards is measured using the closing price of our stock on the date of grant. We recognized compensation expense related to restricted stock awards of $0.4 million and $0.6 million for the three months ended September 30, 2011 and 2010, respectively, and $1.1 million and $1.4 million for the nine months ended September 30, 2011 and 2010, respectively.

As of September 30, 2011, there was $0.7 million of unrecognized compensation expense, net of estimated forfeitures, related to unvested restricted stock awards. This amount is expected to be recognized over a weighted-average period of 0.81 years.

The compensation expense is recognized ratably over the estimated vesting period. The vesting restrictions for outstanding restricted stock units generally lapse over a period of 48 to 60 months.

The fair value of the unvested restricted stock units is measured using the closing price of our stock on the date of grant. We recognized compensation expense related to restricted stock units of $2.3 million and $1.2 million for the three months ended

September 30, 2011 and 2010, respectively, and $5.0 million and $2.3 million for the nine months ended September 30, 2011 and 2010, respectively. For the three months and nine months ended September 30, 2011, stock-based compensation expense was adjusted by $0.7 million as the achievement of certain performance measures was deemed probable. For the three months and nine months ended September 30, 2010, stock-based compensation expense was adjusted by $0.5 million as the achievement of certain performance measures was deemed probable.

As of September 30, 2011, there was $15.0 million of unrecognized compensation expense, net of estimated forfeitures, related to unvested restricted stock units. This amount is expected to be recognized over a weighted-average period of 2.79 years.

Employee Stock Purchase Plan

The ESPP allows eligible employees to purchase our common stock at 85% of the lower of the stock price at the beginning or end of the offering period, which generally is a six-month period. During the nine months ended September 30, 2011, 41,558 shares were purchased under the ESPP for $0.8 million. We recognized compensation expense related to the ESPP of $0.1 million for each of the three months ended September 30, 2011 and 2010, and $0.4 million and $0.3 million for the nine months ended September 30, 2011 and 2010, respectively.

10. Fair Value Measurement

We measure the fair value of assets and liabilities using a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

 

   

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities.

 

   

Level 2 — Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

 

   

Level 3 — Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

The fair value measurement of an asset or liability is based on the lowest level of any input that is significant to the fair value assessment. Our investments that are measured at fair value on a recurring basis are generally classified within Level 1 or Level 2 of the fair value hierarchy.

The following table presents our financial assets and liabilities that were accounted for at fair value as of September 30, 2011 by level within the fair value hierarchy (in thousands):

We estimated the fair value of the acquisition-related contingent consideration using a probability-weighted discounted cash flow model. This fair value was classified as Level 3 because it was based on significant unobservable inputs that are supported by little or no market activity and reflect our own assumptions. During the period ended September 30, 2011, we recognized a $0.1 million increase in the fair value of the acquisition-related contingent consideration related primarily to the change in the discount period (accretion due to the passage of time).

Assets and liabilities that are measured at fair value on a non-recurring basis include intangible assets and goodwill. These items are adjusted to fair value if and when they are considered to be impaired. For the nine months ended September 30, 2011, there were no fair value adjustments for assets and liabilities measured on a non-recurring basis.

12. Commitments and Contingencies

Contract Manufacturer Commitments – We purchase components for our products from a variety of suppliers and use several contract manufacturers to provide manufacturing services for our products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, we enter into agreements with contract manufacturers and suppliers that allow them to procure inventory based upon information we provide. In certain instances, these agreements allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to firm orders being placed. A portion of our reported purchase commitments arising from these agreements are firm, non-cancelable, and unconditional commitments. As of September 30, 2011, we had total purchase commitments for inventory of approximately $21.1 million due within the next 12 months. Of this amount, $14.6 million relates to our newly introduced FirePOWER line of products and $6.5 million relates to our existing line of products. For the three months ended September 30, 2011, we recognized $1.0 million of expense for purchase commitments we have made to our contract manufacturers for the product and component inventory that has been estimated to be in excess of future demand for existing products due to the introduction of our new products. We recorded this cost as a component of product cost of revenue and a liability in other accrued expenses. It is reasonably possible that our estimate of future demand for our products could change in the near term and result in additional inventory or commitment reserves which would negatively impact our future results of operations.

Asset Retirement Obligation – We maintain office space in the United Kingdom for which the lease agreement requires that we return the office space to its original condition upon vacating the premises. The present value of the costs associated with this retirement obligation is approximately $140,000, payable upon termination of the lease. This liability is being accreted over the lease term.

Indemnification – Our agreements with customers, as well as our reseller agreements, include certain provisions for indemnifying customers and resellers and their affiliated parties against damages and liabilities arising from third-party claims if our products infringe another party’s intellectual property rights. Our exposure under these indemnification provisions is generally limited to the total amount paid by the customer or reseller, as applicable, under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to liabilities in excess of the amount received under the agreement. To date, there have been no liabilities incurred under such indemnification provisions.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes that appear elsewhere in this Quarterly Report on Form 10-Q and with our Annual Report on Form 10-K for the fiscal year ended December 31, 2010.

Introduction

Management’s discussion and analysis of financial condition, changes in financial condition and results of operations is provided as a supplement to the accompanying consolidated financial statements and notes to help provide an understanding of Sourcefire, Inc.’s financial condition and results of operations. This item of our Quarterly Report on Form 10-Q is organized as follows:

 

   

Overview. This section provides a general description of our business, the key financial metrics that we use in assessing our performance, and anticipated trends that we expect to affect our financial condition and results of operations.

 

   

Results of Operations. This section provides an analysis of our results of operations for the three months and nine months ended September 30, 2011 and 2010.

 

   

Non-GAAP Financial Measures. This section discusses non-GAAP financial results that we use in evaluating the operating performance of our business. These measures should be considered in addition to results prepared in accordance with United States generally accepted accounting principles, or GAAP, but should not be considered a substitute for, or superior to, GAAP results. The non-GAAP measures discussed have been reconciled to the nearest GAAP measure in a table included in this section.

 

   

Liquidity and Capital Resources. This section provides an analysis of our cash flows for the nine months ended September 30, 2011 and a discussion of our capital requirements and the resources available to us to meet those requirements.

 

   

Critical Accounting Policies and Estimates. This section discusses accounting policies that are considered important to our financial condition and results of operations, require significant judgment or require estimates on our part in applying them. Our significant accounting policies, including those considered to be critical accounting policies, are summarized in Note 2 to the accompanying consolidated financial statements.

Key Financial Metrics and Trends

For the first three quarters of 2011, we have seen strong sales to U.S. commercial and international customers. Our revenues from U.S. commercial customers increased by 25% and 31% for the three months and nine months ended September 30, 2011, respectively, as compared to the prior-year period. Similarly, our revenues from international customers increased by 41% and 28% for the three months and nine months ended September 30, 2011, respectively, as compared to the prior-year period. We expect to continue to see growth in our U.S. commercial and international business through the remainder of 2011, although our ability to achieve this expected growth and the rate of any growth is subject to numerous factors as discussed in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2010.

The growth rate in our sales to U.S. federal government agencies for the first three quarters of 2011 has been negatively affected by reduced federal spending levels. We expect this trend to continue for the remainder of 2011 and into 2012 as a result of the federal government again operating under a continuing budget resolution and related disruptions in the procurement activities of federal agencies. Our revenues from U.S. federal and state government agencies increased by 16% and 1% for the three months and nine months ended September 30, 2011, respectively, as compared to the prior-year period. We expect our revenue from U.S. federal and state government agencies for the year ended December 31, 2011 to increase slightly as compared to the prior year. We further expect that a low growth rate in federal revenue will result in a decline in our overall revenue growth rate for 2011, as compared to the prior year, although we continue to expect positive overall revenue growth, primarily as a result of strength in our U.S. commercial and international business.

We evaluate our performance on the basis of several key financial metrics, including revenue, cost of revenue, gross profit, and operating expenses. We compare these key performance indicators, on a quarterly basis, to both target amounts established by management and to our performance for prior periods. We also evaluate performance on the basis of adjusted income from operations, adjusted income from operations as a percentage of revenue, adjusted net income, adjusted net income per share and free cash flow, which are non-GAAP financial measures. Information regarding our non-GAAP financial measures and a reconciliation of each to the nearest GAAP measure is provided under “Non-GAAP Financial Measures” below.

Revenue

We currently derive revenue from product sales and services. Product revenue is principally derived from the sale of our network security solutions. Our network security solutions include a perpetual software license bundled with a third-party hardware platform. Services revenue is principally derived from technical support and professional services. We typically sell technical support to complement our network security product solutions.

Technical support entitles a customer to product updates and new rule releases on a when and if available basis and both telephone and web-based assistance for using our products. Our professional services revenue includes optional installation, configuration and tuning, which we refer to collectively as network security deployment services. These services typically occur on-site after delivery has occurred.

Product sales are typically recognized as revenue upon shipment of the product to the customer. For sales through resellers and distributors, we recognize revenue upon the shipment of the product only if those resellers and distributors provide us, at the time of placing their order, with the identity of the end-user customer to whom the product has been sold. We recognize revenue from services when the services are performed. For technical support services, we recognize revenue ratably over the term of the support arrangement, which is generally 12 months. Our support agreements generally provide for payment in advance.

We sell our network security solutions globally. However, 77% and 80% of our revenue for the three months ended September 30, 2011 and 2010, respectively, and 75% and 76% of our revenue for the nine months ended September 30, 2011 and 2010, respectively, was generated by sales to U.S.-based customers. We expect that our revenue from customers based outside of the United States will increase in absolute dollars and as a percentage of revenue as we strengthen our international presence.

We continue to generate a majority of our product revenue through sales to existing customers, both for new locations and for additional technology to protect existing networks and locations. Product sales to existing customers accounted for 54% and 59% of total product revenue for the three months ended September 30, 2011 and 2010, respectively, and 65% and 62% of total product revenue for the nine months ended September 30, 2011 and 2010, respectively. We expect product sales to existing customers to continue to account for a significant portion of our product revenue in 2011.

Table of Contents

Historically, our product revenue has been seasonal, with a significant portion of our total product revenue in recent fiscal years generated in the third and fourth quarters. Revenue from our government customers has been influenced by the September 30th fiscal year-end of the U.S. federal government, which has historically resulted in our revenue from government customers being highest in the second half of the year. While we expect these historical trends to continue, they could be affected by a number of factors, including another decline in general economic conditions, changes in the timing or amounts of U.S. government spending and our planned international expansion. Notwithstanding these general seasonal patterns, our revenue within a particular quarter is often affected significantly by the unpredictable procurement patterns of our customers. Our prospective customers usually spend a long time evaluating and making purchase decisions for network security solutions. Historically, many of our customers have not finalized their purchasing decisions until the final weeks or days of a quarter. We expect these purchasing patterns to continue in the future. Therefore, a delay in even one large order beyond the end of the quarter could materially reduce our anticipated revenue for a quarter. In addition, because we typically recognize revenue upon shipment, the timing of our quarter-end and year-end shipments could materially affect our reported product revenue for a given quarter or year. Delayed orders could negatively impact our results of operations and cash flows for a particular period and could therefore cause us to fail to meet the financial performance expectations of financial and industry research analysts or investors.

Cost of Revenue

Cost of product revenue includes the cost of the hardware platform, third-party manufacturing costs, royalties for third-party software, personnel costs associated with logistics and quality control, stock-based compensation expense, amortization of acquired intangible assets, supplies, warranty, shipping and handling costs, expense for inventory excess and obsolescence and depreciation in the instances where we lease our network security solutions to our customers. We allocate overhead costs, including facilities, supplies, communication and information systems and employee benefits, to the cost of product revenue. Overhead costs are reflected in each cost of revenue and operating expense category. As our product volume increases, we anticipate incurring an increased amount of both direct and overhead expenses to supply and manage the increased volume. In addition, hardware unit costs or other costs of manufacturing could increase in the future. For the nine months ended September 30, 2011, write-downs for excess and obsolete inventory increased significantly compared to the prior-year period as a result of new product introductions. In addition, in the third quarter of 2011, we recognized $1.0 million of expense in product cost of revenue for purchase commitments we have made to our contract manufacturers for the product and component inventory that has been estimated to be in excess of future demand for existing products due to the introduction of our new products. It is reasonably possible that our estimate of future demand for our products could change in the near term and result in additional inventory or commitment reserves which would negatively impact our future results of operations.

Cost of services revenue includes the direct labor costs of our employees and outside consultants engaged to furnish those services, as well as their travel and associated direct material costs and stock-based compensation expense. Additionally, we include in cost of services revenue an allocation of overhead costs, as well as the cost of time and materials to service or repair the hardware component of our products covered under a renewed support arrangement beyond the manufacturer’s warranty, the amortization of a long-term contract for a third-party to provide maintenance and support services for certain product offerings and the expense for advance replacement unit inventory excess and obsolescence. As our customer base continues to grow, we anticipate incurring an increasing amount of these service and repair costs, as well as costs for additional personnel to provide support and service to our customers.

Gross Profit

Our gross profit is affected by a variety of factors, including competition, the mix and average selling prices of our products, our pricing policy, new product introductions, the cost of hardware platforms, expense for inventory excess and obsolescence, warranty expense, the cost of labor and materials and the mix of distribution channels through which our products are sold. Our gross profit would be adversely affected by price declines or pricing discounts if we are unable to reduce costs on existing products and fail to introduce new products with higher margins. Currently, product sales typically have a lower gross profit as a percentage of revenue than our services due to the cost of the hardware platform. Our gross profit for any particular quarter could be adversely affected if we do not complete a sufficient level of sales of higher-margin products by the end of the quarter. As discussed above, many of our customers do not finalize purchasing decisions until the final weeks or days of a quarter, so a delay in even one large order of a high-margin product could significantly reduce our total gross profit percentage for that quarter.

Operating Expenses

Research and Development. Research and development expenses consist primarily of salaries, incentive compensation and allocated overhead costs for our engineers; stock-based compensation expense; retention obligations related to our hiring of former Immunet employees; costs for professional services to design, test and certify our products; and costs associated with data used by us in our product development.

We have expanded our research and development capabilities and expect to continue to expand these capabilities in the future. We are committed to increasing the level of innovative design and development of new products as we strive to enhance our ability to serve our existing commercial and federal government markets as well as new markets for security solutions. To meet the changing requirements of our customers, we will need to fund investments in several development projects in parallel. Accordingly, we anticipate that our research and development expenses will continue to increase in absolute dollars and increase significantly as a percentage of revenue for the year ending December 31, 2011.

Sales and Marketing. Sales and marketing expenses consist primarily of salaries, incentive compensation and allocated overhead costs for sales and marketing personnel; stock-based compensation expense; trade show, advertising, marketing and other brand-building costs; marketing consultants and other professional services; training, seminars and conferences; and travel and related costs.

As we continue to focus on increasing our market penetration, expanding internationally, increasing our indirect sales channel and building brand awareness, we anticipate that selling and marketing expenses will continue to increase in absolute dollars and increase modestly as a percentage of revenue for the year ending December 31, 2011.

General and Administrative. General and administrative expenses consist primarily of salaries, incentive compensation and allocated overhead costs for executive, legal, finance, information technology, human resources and administrative personnel; stock-based compensation expense; corporate development expenses and professional fees related to legal, audit, tax and regulatory compliance; travel and related costs; and corporate insurance. We anticipate that general and administrative expenses will increase in absolute dollars for the year ending December 31, 2011.

Stock-Based Compensation. Stock-based compensation expense is based on the grant date fair value of stock awards. We use the Black-Scholes option pricing model to estimate the fair value of stock options granted and employee stock purchases. The use of option valuation models requires the input of highly subjective assumptions, including the expected term and the expected stock price volatility. Based on the estimated grant date fair value of stock-based awards, we recognized aggregate stock-based compensation expense of $4.3 million and $3.0 million for the three months ended September 30, 2011 and 2010, respectively, and $10.8 million and $6.9 million for the nine months ended September 30, 2011 and 2010, respectively.

The increase in our product revenue for the three months and nine months ended September 30, 2011, as compared to the prior-year period, was primarily due to increased sales revenue from U.S. commercial and international customers and the sales product mix favoring our higher priced sensor products.

The increase in our services revenue for the three months and nine months ended September 30, 2011, as compared to the prior-year period, resulted from an increase in our installed customer base due to new product sales in which associated support was purchased, as well as technical support renewals by our existing customers.

Research and development expenses for the three months ended September 30, 2011 increased over the prior-year period, primarily due to an increase of $1.7 million in salaries, incentive compensation and benefits as a result of additional personnel, including the hiring of former Immunet employees, an increase of $0.8 million in consulting fees, $0.7 million for the accrual of retention obligations related to our hiring of former Immunet employees and an increase of $0.6 million in stock-based compensation expense.

Research and development expenses for the nine months ended September 30, 2011 increased over the prior-year period, primarily due to an increase of $4.6 million in salaries, incentive compensation and benefits as a result of additional personnel, including the hiring of former Immunet employees, an increase of $2.2 million in consulting fees, $2.0 million for the accrual of retention obligations related to our hiring of former Immunet employees and an increase of $1.4 million in stock-based compensation expense.

Sales and marketing expenses for the three months ended September 30, 2011 increased over the prior-year period, primarily due to an increase of $2.4 million in salaries, commissions and incentive compensation, and benefits as a result of additional personnel, an increase of $0.5 million in stock-based compensation expense, an increase of $0.5 million in travel and travel-related expenses and an increase of $0.2 million in advertising, promotion, partner-marketing programs and trade show expenses.

Sales and marketing expenses for the nine months ended September 30, 2011 increased over the prior-year period, primarily due to an increase of $6.4 million in salaries, commissions and incentive compensation, and benefits as a result of additional personnel, an increase of $1.8 million in stock-based compensation expense, an increase of $1.0 million in travel and travel-related expenses and an increase of $0.5 million in advertising, promotion, partner-marketing programs and trade show expenses.

General and administrative expenses for the three months ended September 30, 2011 decreased from the prior-year period, primarily due to a net decrease of $0.2 million in professional fees and a decrease of $0.2 million in salaries, incentive compensation, and benefits, partially offset by an increase of $0.1 million in stock-based compensation expense.

General and administrative expenses for the nine months ended September 30, 2011 increased slightly from the prior-year period, primarily due to an increase of $0.6 million in stock-based compensation expense, offset by a net decrease of $0.5 million in professional fees.

Depreciation and amortization expense for the three months and nine months ended September 30, 2011 increased from the prior-year period, primarily due to depreciation of additional lab and testing equipment purchased for our engineering department and computers purchased for personnel hired.

Our effective tax rate for the three months ended September 30, 2011 is an expense of 42%, compared to an expense of 17% in the prior-year period. Our effective tax rate for the nine months ended September 30, 2011 is a benefit of 757%, compared to a benefit of 70% in the prior-year period. Our benefit from income taxes for the nine months ended September 30, 2011 is based on an estimated annual effective tax rate for 2011 of 38.1% and a discrete tax benefit of $2.0 million from research and experimentation tax credits for the years 2003 through 2010 recorded in the first quarter of 2011. Our 2011 estimated annual effective tax rate includes the U.S. federal statutory rate of 34%, state income taxes and foreign income taxed at different rates, partially offset by the impact of research and experimentation tax credits projected for 2011. The net benefit recorded for the nine months ended September 30, 2010 was primarily due to a tax benefit of $7.6 million recorded upon our decision in the second quarter of 2010 to release the valuation allowance recorded against our deferred tax assets in the U.S.

In the first quarter of 2011, we established a liability of $0.3 million for uncertain tax positions recognized in the current year. The amount of the reserve for uncertain tax benefits that, if released, would impact the effective tax rate was $0.3 million as of September 30, 2011.

Our future effective tax rate may be materially impacted by the amount of income taxes associated with our foreign earnings, which are taxed at rates different from the U.S. federal statutory rate, as well as the timing and extent of the realization of deferred tax assets and changes in the tax law. Further, our effective tax rate may fluctuate within a fiscal year, including from quarter-to-quarter, due to items arising from discrete events, including the resolution or identification of tax position uncertainties and acquisitions of other companies.

Our product revenue has tended to be seasonal, with a significant portion generated in the third and fourth quarters. Revenue from our government customers has been influenced by the September 30th fiscal year-end of the U.S. federal government, which has historically resulted in our revenue from government customers being highest in the second half of the year. In the fourth quarter, revenues have historically been strong due to purchases by North American enterprise customers, which operate on a calendar year budget and often wait until the fourth quarter to make their most significant capital equipment purchases. In addition, increased fourth quarter sales in Europe have historically resulted in higher fourth quarter revenues following a decline in sales in the summer months due to vacation practices in Europe and the resulting delay in capital purchase activities until the fall. While we expect these historical trends to continue, they could be affected by a number of factors, including another decline in general economic conditions, changes in the timing or amounts of U.S. government spending, and our planned international expansion. The timing of transactions could materially affect our quarterly or annual product revenue.

Quarterly Timing

On a quarterly basis, we have usually generated the majority of our sales in the final month of the quarter. We believe this occurs for two reasons. First, many customers wait until the end of the quarter to extract favorable pricing terms from their vendors, including Sourcefire. Second, our sales personnel, who have a strong incentive to meet quarterly sales targets, have tended to increase their sales activity as the end of a quarter nears, while their participation in sales management review and planning activities is typically scheduled at the beginning of a quarter. The timing of our quarter-end and year-end shipments also affects our quarterly and annual product revenue, since we typically recognize revenue upon shipment of the product.

Non-GAAP Financial Measures

Adjusted Net Income, Adjusted Net Income per Share, Adjusted Income from Operations and Adjusted Income from Operations as a Percentage of Revenue: In evaluating the operating performance of our business, we exclude certain charges and credits that are required by GAAP. We believe these non-GAAP results provide useful information to both management and investors by excluding (i) stock-based compensation, which does not involve the expenditure of cash, (ii) amortization of acquisition-related intangible assets, which does not involve the expenditure of cash, and (iii) other acquisition-related expenses, which are unrelated to the ongoing operation of our business in the ordinary course. For all of 2011 we expect that non-GAAP results will continue to be adjusted to reflect the effect of an assumed tax rate of 35%. We believe this adjustment provides useful information to both management and investors.

Free Cash Flow: We define free cash flow as net cash provided by operating activities minus capital expenditures. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the purchase of property and equipment, can be used for strategic opportunities, including investing in the business, making strategic acquisitions and strengthening the balance sheet.

These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.

Operating Activities. Cash used in operating activities for the nine months ended September 30, 2011 is the result of changes in our operating assets and liabilities of $17.4 million, which includes a payment of $11.0 million for a long-term contract for a third-party to provide maintenance and support services for certain product offerings, offset by our net income of $2.1 million and $14.9 million of net non-cash revenues and expenses. Cash provided by operating activities for the nine months ended September 30, 2010 is the result of our net income of $15.6 million, $2.2 million of net non-cash revenues and expenses, which includes $7.6 million related to the release of the valuation allowance on our deferred tax assets, and changes in our operating assets and liabilities of $1.8 million.

Investing Activities. Cash used in investing activities for the nine months ended September 30, 2011 was primarily the result of purchases of investments of $118.1 million, $7.1 million for acquisition-related payments and capital expenditures of $4.3 million, partially offset by maturities of investments of $122.9 million. Cash used in investing activities for the nine months ended September 30, 2010 was primarily the result of purchases of investments of $80.1 million and capital expenditures of $4.4 million, partially offset by maturities of investments of $81.9 million.

Financing Activities. Cash provided by financing activities for the nine months ended September 30, 2011 and 2010 was primarily the result of proceeds from the issuance of common stock under our employee stock-based plans.

Liquidity Requirements

We manufacture our products through contract manufacturers and other third parties. This approach provides us with the advantage of relatively low capital expenditure requirements and significant flexibility in scheduling production and managing inventory levels. The majority of our products are delivered to our customers directly from our contract manufacturers. Accordingly, our contract manufacturers are responsible for purchasing and stocking the components required to produce our products, and they invoice us when the finished goods are shipped. By leasing our office facilities, we also minimize the cash needed for expansion. Our capital spending is generally limited to leasehold improvements, computers, office furniture and lab and test equipment.

Our short-term liquidity requirements through September 30, 2012 consist primarily of the funding of working capital requirements, capital expenditures and the remaining payments related to our acquisition of Immunet. We expect to meet these short-term requirements primarily through cash flow from operations. To the extent that cash flow from operations is not sufficient to meet these requirements, we expect to fund these amounts through the use of existing cash and investment resources. As of September 30, 2011, we had cash, cash equivalents and investments of $144.1 million and working capital of $124.4 million.

As described above, our product sales are, and are expected to continue to be, highly seasonal. We believe that our current cash reserves are sufficient for any short-term needs arising from the seasonality of our business.

Table of Contents

Our long-term liquidity requirements consist primarily of obligations under our operating leases. We expect to meet these long-term requirements primarily through cash flow from operations.

In addition, we may utilize cash resources, equity financing or debt financing to fund acquisitions or investments in complementary businesses, technologies or product lines.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates.

We believe that, of our significant accounting policies, which are described in Note 2 to the consolidated financial statements contained in this report, the following accounting policies involve a greater degree of judgment and complexity. Accordingly, we believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our consolidated financial condition and results of operations.

Revenue Recognition. We derive revenue from arrangements that include hardware products with embedded software, software licenses and royalties, technical support, and professional services. Revenue from products in the accompanying consolidated statements of operations consists primarily of sales of hardware appliances containing software, but also includes fees and royalties for the license of our technology in a software-only format and subscriptions to receive rules released by the Vulnerability Research Team, or VRT, that are used to update the appliances for current exploits and vulnerabilities. Technical support, which generally has a contractual term of 12 months, includes telephone and web-based support, software updates, and rights to software upgrades on a when-and-if-available basis. Professional services include training and consulting.

For each arrangement, we recognize revenue when: (a) persuasive evidence of an arrangement exists (e.g., a signed contract); (b) delivery of the product has occurred and there are no remaining obligations or substantive customer acceptance provisions; (c) the fee is fixed or determinable; and (d) collection of the fee is deemed probable.

For sales through resellers and distributors, we recognize revenue upon the shipment of the product only if those resellers and distributors provide us, at the time of placing their order, with the identity of the end-user customer to whom the product has been sold. To the extent that a reseller or distributor requests an inventory or stock of products, we defer revenue on that product until we receive notification that it has been sold through to an identified end-user.

All amounts billed or received in excess of the revenue recognized are included in deferred revenue. In addition, we defer all direct costs associated with revenue that has been deferred. These amounts are included in either prepaid expenses and other current assets or inventory in the accompanying balance sheets, depending on the nature of the costs and the reason for the deferral.

In October 2009, the Financial Accounting Standards Board, or 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:

 

  (i) 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;

 

  (ii) require an entity to allocate arrangement consideration to each element based on a selling price hierarchy, where the selling price for an element is based on vendor-specific objective evidence, or VSOE, if available; third-party evidence, or TPE, if available and VSOE is not available; or the best estimate of selling price, or BESP, if neither VSOE or TPE is available; and

 

  (iii) eliminate the use of the residual method and require an entity to allocate arrangement consideration based on the relative selling price of each element within the arrangement.

 

31


Table of Contents

We adopted this accounting guidance on January 1, 2011 on a prospective basis for applicable transactions originating or materially modified after December 31, 2010.

The majority of our products are hardware appliances containing software components that operate together to provide the essential functionality of the product. Therefore, our hardware appliances are considered non-software deliverables and are no longer accounted for under the industry-specific software revenue recognition guidance.

Our product revenue also includes revenue from the sale of stand-alone software products. Stand-alone software may operate on our hardware appliance, but is not considered essential to the functionality of the hardware. Stand-alone software sales generally include a perpetual license to our software. Stand-alone software sales continue to be subject to the industry-specific software revenue recognition guidance.

For stand-alone software sales after December 31, 2010 and for all transactions entered into prior to the first quarter of 2011, we recognize revenue based on software revenue recognition guidance. Under the software revenue recognition guidance, we allocate the total arrangement fee among each deliverable based on the fair value of each of the deliverables, determined based on VSOE. If VSOE of fair value does not exist for each of the deliverables, all revenue from the arrangement is deferred until the earlier of the point at which sufficient VSOE of fair value can be determined for any undelivered elements or all elements of the arrangement have been delivered. If the only undelivered elements are elements for which we currently have VSOE of fair value, we recognize revenue for the delivered elements based on the residual method. When VSOE of fair value does not exist for undelivered elements such as maintenance and support, the entire arrangement fee is recognized ratably over the performance period.

For all transactions originating or materially modified after December 31, 2010, we recognize revenue in accordance with the amended accounting guidance. Certain arrangements with multiple deliverables may continue to have stand-alone software deliverables that are subject to the existing software revenue recognition guidance along with non-software deliverables that are subject to the amended revenue accounting guidance. The revenue for these multiple deliverable arrangements is allocated to the stand-alone software deliverables as a group and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the fair value hierarchy in the amended revenue accounting guidance.

We have established VSOE of fair value for substantially all of our technical support based upon actual renewals of each type of technical support that is offered and for each customer class. Technical support and technical support renewals are currently priced based on a percentage of the list price of the respective product or software and historically have not varied from a narrow range of values in the substantial majority of our arrangements. Revenue related to technical support is deferred and recognized ratably over the contractual period of the technical support arrangement, which is generally 12 months. The VSOE of fair value of our other services is based on the price for these same services when they are sold separately. Revenue for professional services that are sold either on a stand-alone basis or included in multiple element arrangements is deferred and recognized as the services are performed.

For our non-software deliverables we allocate the arrangement consideration based on the relative selling price of the deliverables. For our hardware appliances we use BESP as our selling price. For our support and services, we generally use VSOE as our selling price.

We are typically not able to determine TPE for our products or services. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis.

When we are unable to establish the selling price of our non-software deliverables using VSOE or TPE, we use BESP in our allocation of arrangement consideration. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. We determine BESP for a product or service by considering multiple factors including, but not limited to, gross margin objectives, pricing practices, customer classes and geographies and distribution channels.

For certain arrangements we will be able to account for more transaction consideration upon delivery than allowed under the prior guidance, primarily due to more deliverables being accounted for as separate units of accounting and the elimination of the use of the residual method and a requirement to allocate arrangement consideration using a selling price hierarchy.

An estimate of the revenue that would have been reported if we had applied the new guidance for multiple deliverable arrangements for non-software deliverables for the three months ended September 30, 2010 is $36.6 million compared to the $36.2 million of revenue recognized under the industry specific software revenue recognition rules and for the nine months ended September 30, 2010 is $93.7 million compared to the $92.6 million of revenue recognized under the industry specific software revenue recognition rules.

We record taxes collected on revenue-producing activities on a net basis.

Changes in our judgments and estimates about these assumptions could materially impact the timing of our revenue recognition.

Accounting for Stock-Based Compensation. Stock-based awards granted include stock options, restricted stock awards, restricted stock units and stock purchased under our Amended and Restated 2007 Employee Stock Purchase Plan, or ESPP. Stock-based compensation expense is measured at the grant date, based on the fair value of the awards, and is recognized as expense over the requisite service period, net of estimated forfeitures.

We use the Black-Scholes option pricing model for estimating the fair value of stock options granted and for employee stock purchases under the ESPP. The use of option valuation models requires the input of highly subjective assumptions, including the expected term and the expected stock price volatility. Additionally, the recognition of expense requires the estimation of the number of options that will ultimately vest and the number of options that will ultimately be forfeited. The fair value of stock-based awards is recognized as expense ratably over the requisite service period, net of estimated forfeitures. We rely on historical experience of employee turnover to estimate our expected forfeitures.

The key assumptions used in the Black-Scholes option valuation of stock options granted under the 2002 Plan and the 2007 Plan and ESPP grants include the following:

Average risk-free interest rate — This is the average U.S. Treasury rate, with a term that most closely resembles the expected life of the option, as of the grant date.

Expected dividend yield — We use an expected dividend yield of zero, as we have never declared or paid dividends on our common stock and do not anticipate paying dividends in the foreseeable future.

Expected life — This is the period of time that the stock options granted under our equity incentive plans and ESPP grants are expected to remain outstanding.

As we do not yet have sufficient historical experience for determining the expected term of the stock options granted, we have based our expected term on the simplified method. This estimate is derived from the average midpoint between the weighted-average vesting period and the contractual term. In future periods, we expect to begin to incorporate our own data in estimating the expected life as we develop appropriate historical experience of employee exercise and post-vesting termination behavior considered in relation to the contractual life of the option. For ESPP grants, the expected life is the plan period.

Expected volatility — Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period.

For stock options granted, since our historical stock data from our IPO in March 2007 is less than the expected life of the stock options, we have used a blended volatility to estimate expected volatility. The blended volatility includes a weighting of our historical volatility from the date of our IPO to the respective grant date and an average of our peer group historical volatility consistent with the expected life of the option. Our peer group historical volatility includes the historical volatility of companies that are similar in revenue size, are in the same industry or are competitors. We expect to continue to use a larger proportion of our historical volatility in future periods as we develop additional historical experience of our own stock price fluctuations considered in relation to the expected life of the option.

For ESPP grants, we use our historical volatility since we have historical data available since our IPO, which is consistent with the expected life.

If we were to employ different assumptions for estimating stock-based compensation expense in future periods, or if we were to decide to use a different valuation model, the amount of expense recorded in future periods could differ significantly from what we have recorded in recent periods.

The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable, which are characteristics that are not present in our option grants. Existing valuation models, including the Black-Scholes and Lattice models, may not provide reliable measures of the fair values of our stock-based compensation awards. Consequently, there is a risk that our estimates of the fair values of our stock-based compensation awards on the grant dates may be significantly different than the actual values upon the exercise, expiration, early termination or forfeiture of those stock-based payments in the future. Certain stock-based payments, such as employee stock options, may expire worthless or otherwise result in zero intrinsic value as compared to the fair values originally estimated on the grant date and reported in our financial statements. Alternatively, values may be realized from these instruments that are significantly higher than the fair values originally estimated on the grant date and reported in our financial statements.

The application of these principles may be subject to further interpretation and refinement over time. There are significant differences among valuation models, and there is a possibility that we will adopt different valuation models in the future. This may result in a lack of consistency between past and future periods and materially affect the fair value estimate of stock-based payments. It may also result in a lack of comparability with other companies that use different models, methods, and assumptions.

Our stock awards are generally subject to service-based vesting; however, in some instances, awards contain provisions for acceleration of vesting upon achievement of performance measures, change in control and in certain other circumstances. On a quarterly basis, we evaluate the probability of achieving performance measures and adjust stock-based compensation expense accordingly. The stock-based compensation expense is recognized ratably over the estimated vesting period. Stock-based compensation expense may fluctuate within a fiscal year, including from quarter-to-quarter, based on the probability of achieving those performance measures.

Accounting for Income Taxes. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities and for tax carryforwards at enacted statutory tax rates in effect for the years in which the differences are expected to reverse.

We assess the realizability of our deferred tax assets, which primarily consist of net operating loss, or NOL, carryforwards, and temporary differences associated with stock-based compensation expense, deferred revenue and research and experimentation tax credit carryforwards. In assessing the realizability of these deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be realized. In assessing the need for a valuation allowance, we consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies.

With respect to foreign earnings, it is our policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. Any excess tax benefit, above amounts previously recorded for stock-based compensation expense, from the exercise of stock options is recorded in additional paid-in-capital in the consolidated balance sheets to the extent that cash taxes payable are reduced.

Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, we make certain estimates and assumptions, in (i) calculating our provision for income taxes, deferred tax assets and deferred tax liabilities, (ii) determining any valuation allowance recorded against deferred tax assets and (iii) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. Our estimates and assumptions may differ significantly from tax benefits ultimately realized.

Allowance for Doubtful Accounts and Sales Return Allowance. We make estimates regarding the collectability of our accounts receivable. When we evaluate the adequacy of our allowance for doubtful accounts, we consider multiple factors, including historical write-off experience, the need for specific customer reserves, the aging of our receivables, customer creditworthiness and changes in customer payment cycles. Historically, our allowance for doubtful accounts has been adequate based on actual results. If any of the factors used to calculate the allowance for doubtful accounts change or if the allowance does not reflect our future ability to collect outstanding receivables, additional provisions for doubtful accounts may be needed, and our future results of operations could be materially affected.

 

34


Table of Contents

We also use our judgment to make estimates regarding potential future product returns related to reported product revenue in each period. We analyze factors such as our historical return experience, current product sales volumes, and changes in product warranty claims when evaluating the adequacy of the sales returns allowance. If any of the factors used to calculate the sales return allowance were to change, we may experience a material difference in the amount and timing of our product revenue for any given period.

Inventory. Inventory consists of hardware and related component parts and is stated at the lower of cost on a first-in, first-out basis, or market, except for evaluation and advance replacement units which are stated at the lower of cost, on a specific identification basis, or market. Evaluation units are used for customer testing and evaluation and are predominantly located at the customers’ premises. Advance replacement units, which include fully functioning appliances and spare parts, are used to provide replacement units under technical support arrangements if a customer’s unit is not functioning properly. We make estimates of forecasted demand for our products, and inventory that is obsolete or in excess of our estimated demand is written down to its estimated net realizable value based on historical usage, expected demand, the timing of new product introductions and age. It is reasonably possible that our estimate of future demand for our products could change in the near term and result in additional inventory write-downs, which would negatively impact our gross margin.

Investments. We determine the appropriate classification of our investments at the time of purchase and reevaluate such classification as of each balance sheet date. Our investments are comprised of money market funds, corporate debt investments, commercial paper, government-sponsored enterprise securities, government securities and certificates of deposit. These investments have been classified as available-for-sale. Available-for-sale investments are stated at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income. Amortization is included in interest and investment income. Interest on securities classified as available-for-sale is also included in interest and investment income.

We evaluate our investments on a regular basis to determine whether an other-than-temporary impairment in fair value has occurred. If an investment is in an unrealized loss position and we have the intent to sell the investment, or it is more likely than not that we will have to sell the investment before recovery of its amortized cost basis, the decline in value is deemed to be other-than-temporary and is charged against earnings for the period. For investments that we do not intend to sell or it is more likely than not that we will not have to sell the investment, but we expect that we will not fully recover the amortized cost basis, the credit component of the other-than-temporary impairment is charged against earnings for the applicable period and the non-credit component of the other-than-temporary impairment is recognized in other comprehensive income on our consolidated statement of stockholders’ equity and comprehensive income (loss). Unrealized losses entirely caused by non-credit related factors related to investments for which we expect to fully recover the amortized cost basis are recorded in accumulated other comprehensive income.

 

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

No material changes in our market risk occurred from December 31, 2010 through September 30, 2011. Information regarding our market risk at December 31, 2010, is contained in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the year ended December 31, 2010.

 

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which are controls and other procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Use of Proceeds

In March 2007, we completed the initial public offering of shares of our common stock. Our portion of the net proceeds from the initial public offering was approximately $83.9 million after deducting underwriting discounts and commissions of $6.5 million and $2.4 million in offering expenses.

We intend to use the net proceeds from the offering for working capital and other general corporate purposes, including financing our growth, developing new products and funding capital expenditures. Pending such usage, we have invested the net proceeds primarily in short-term, interest-bearing investment grade securities.

Repurchase of Equity Securities During the Period Ended September 30, 2011

The following table provides information about purchases by us during the three months ended September 30, 2011 of equity securities that are registered by us pursuant to Section 12 of the Securities Exchange Act.

Repurchases are made under the terms of our 2007 Equity Incentive Plan. Under this plan, we may award shares of restricted stock to our employees. These shares of restricted stock typically are subject to a lapsing right of repurchase by us. We may exercise this right of repurchase in the event that a restricted stock recipient’s service to us is terminated. If we exercise this right, we are required to repay the purchase price paid by or on behalf of the recipient for the repurchased restricted shares, which typically is the par value per share of $0.001. Repurchased shares are returned to the 2007 Equity Incentive Plan and are available for future awards under the terms of that plan.

These were the only repurchases of equity securities made by us during the three months ended September 30, 2011. We do not currently have a stock repurchase program.
