General and Financial Statement Components [Abstract]

General

NOTE A — General

Business Description

We are a leading provider of on-demand supply chain management solutions, providing integration, collaboration, connectivity, visibility and data analytics to thousands of customers worldwide. We provide our solutions through SPSCommerce.net, a hosted software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill orders. We deliver our solutions to our customers over the Internet using a Software-as-a-Service model and derive the majority of our revenues from thousands of monthly recurring subscriptions from businesses that utilize our solutions.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SPS Commerce, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.

Certain reclassifications have been made to present prior year’s cash flow statement and footnote information consistently with the current year presentation.

Use of Estimates

Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Business Combinations

We recognize separately from goodwill the fair value of the assets acquired and the liabilities assumed at the acquisition date. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date amounts of the assets acquired and the liabilities assumed. Assets acquired include tangible and intangible assets. We determine the value and useful lives of purchased intangible assets with the assistance of an independent third-party valuation firm using certain estimates and assumptions.

While we use estimates and assumptions that we believe are reasonable as a part of the purchase price allocation process to accurately value the assets acquired and the liabilities assumed at the acquisition date, they are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the fair value of the assets acquired and the liabilities assumed based on new information about facts and circumstances that existed as of the acquisition date. Any such adjustments would be recorded as an offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair values, whichever comes first, any subsequent adjustments would be recorded in our consolidated statements of operations.

Segment Information

We operate in and report on one segment, supply chain management solutions.

Risk and Uncertainties

We rely on hardware and software licensed from third parties to offer our on-demand solutions. Our management believes alternate sources are available; however, disruption or termination of these relationships could adversely affect our operating results in the near term.

Fair Value of Financial Instruments

The carrying amounts of our financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable and other accrued expenses, approximates fair value due to their short maturities. Based on borrowing rates currently available to us for loans with similar terms, the carrying value of our outstanding debt and capital lease obligations, if any, approximates fair value.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist principally of temporary cash investments in financial institutions in excess of federally insured limits and trade accounts receivable. Temporary cash investments are held with financial institutions that we believe are subject to minimal risk.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid investments with original maturities when purchased of less than 90 days.

Accounts Receivable

Accounts receivable are initially recorded upon the sale of solutions to customers. Credit is granted in the normal course of business without collateral. Accounts receivable are stated net of allowances for doubtful accounts, which represent estimated losses resulting from the inability of customers to make the required payments. Accounts that are outstanding longer than the contractual terms are considered past due. When determining the allowances for doubtful accounts, we take several factors into consideration including the overall composition of the accounts receivable aging, our prior history of accounts receivable write-offs, the type of customers and our day-to-day knowledge of specific customers. We write off accounts receivable when they become uncollectible. Changes in the allowances for doubtful accounts are recorded as bad debt expense and are included in general and administrative expense in our consolidated statements of operations.

Property and Equipment

Property and equipment, including assets acquired under capital lease obligations, are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the shorter of the estimated useful lives of the individual assets or the lease term. The estimated useful lives are:

Computer equipment and purchased software: 2 to 5 years

Office equipment and furniture: 5 to 7 years

Leasehold improvements: 2 to 7 years

Significant additions or improvements extending asset lives beyond one year are capitalized, while repairs and maintenance are charged to expense as incurred. The assets and related accumulated depreciation and amortization accounts are adjusted for asset retirements and disposals with the resulting gain or loss included in net income (loss).

Research and Development

Costs incurred to develop software applications used in our on-demand supply chain management solutions may be capitalized. Capitalizable costs consist of (a) certain external direct costs of materials and services incurred in developing or obtaining internal-use computer software and (b) payroll and payroll-related costs for employees who are directly associated with, and who devote time to, the project. These costs generally consist of internal labor during configuration, coding and testing activities. Research and development costs incurred during the preliminary project stage, or costs incurred for data conversion activities, training, maintenance and general and administrative or overhead costs, are expensed as incurred. Costs that cannot be separated between the maintenance of, and relatively minor upgrades and enhancements to, internal-use software are also expensed as incurred. Capitalization begins when (a) the preliminary project stage is complete, (b) management with the relevant authority authorizes and commits to the funding of the software project, (c) it is probable the project will be completed, (d) the software will be used to perform the functions intended, and (e) certain functional and quality standards have been met. Historically, no projects have had material costs beyond the preliminary project stage.

Our research and development efforts during 2011, 2010 and 2009 were primarily maintenance and data conversion activities related to our on-demand supply chain management solutions. As such, we did not capitalize any research and development costs during 2011, 2010 or 2009.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. We test goodwill for impairment annually at December 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test is conducted by comparing the fair value of the net assets with the carrying value of the reporting unit. Fair value is determined using the direct market observation of market price and outstanding equity of the reporting unit at December 31. If the carrying value of the goodwill exceeds the fair value of the reporting unit, goodwill may be impaired. If this occurs, the fair value is then allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of goodwill. This implied fair value is then compared to the carrying amount of goodwill and, if it is less, we would recognize an impairment loss. For the year ended December 31, 2009, the impairment test compared the carrying value of the company to the fair value of the company, which was based on an analysis of the discounted future cash flows. The methodology for evaluating the fair value of the company was changed with the completion of our initial public offering to use the per share prices as a direct market observable measure. There has been no impairment of our goodwill to date.

Intangible Assets

Assets acquired in business combinations may include identifiable intangible assets such as subscriber relationships and non-competition agreements. We recognize separately from goodwill the fair value of the identifiable intangible assets acquired. We have determined the fair value and useful lives of our purchased intangible assets with the assistance of an independent third-party valuation firm using certain estimates and assumptions.

The purchased intangible assets are being amortized on a straight-line basis over their estimated useful lives, which is three to seven years for subscriber relationships and two to three years for non-competition agreements. We also have non-competition agreements from a previous acquisition that are amortized on a straight-line basis over the term of the agreements, which begins with the termination of employment of the respective employee(s).

Impairment of Long-Lived Assets

We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset at the date it is tested for recoverability, whether in use or under development. An impairment loss is measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. There has been no impairment of our long-lived assets to date.

Revenue Recognition

We generate revenues by providing a number of solutions to our customers. These solutions include Trading Partner Integration, Trading Partner Enablement and Trading Partner Intelligence. All of our solutions are hosted applications that allow customers to meet their supply chain management requirements. Revenues from our Trading Partner Integration and Trading Partner Intelligence solutions are generated through set-up fees and a recurring monthly hosting fee. Revenues from our Trading Partner Enablement solutions are generally one-time service fees. Sales taxes are presented on a net basis within revenue.

Revenues are recorded in accordance with Staff Accounting Bulletin 104, Revenue Recognition in Financial Statements and Accounting Standards Update (“ASU”) 2009-13, Multiple-Deliverable Revenue Arrangements, when all of the following criteria are met: (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the fee is fixed and determinable, and (4) collectability is probable. If collection is not considered probable, revenues are recognized when the fees are collected. The services related to these fees have standalone value which is determined using vendor specific objective evidence (“VSOE”).

Fees related to our Trading Partner Integration and Trading Partner Intelligence solutions consist of two revenue sources: set-up fees and recurring monthly hosting fees. All set-up fees are deferred and recognized ratably over the expected life of the customer relationship, which is generally two years. We continue to evaluate and adjust the length of these amortization periods as more experience is gained with customer renewals, contract cancellations and technology changes requested by our customers. It is possible that, in the future, the estimates of expected customer lives may change and, if so, the periods over which such subscription set-up fees and costs are amortized will be adjusted. Any such change in estimated expected customer lives will affect our future results of operations. Set-up fees are further broken down as initial set-up fees and add-on set-up fees. Add-on set-up fees, which are nonrefundable, and our Trading Partner Integration revenues represent arrangements providing standalone value for our customers. Because these revenues are not dependent on the delivery of any future performance and the arrangement includes VSOE for pricing, ASU 2009-13 has not impacted how we separate and price these two elements. Initial setup fees are nonrefundable upfront fees that do not have standalone value and are not part of the multiple element arrangement. These fees are deferred and recognized over the customer relationship period as discussed above.

The recurring monthly fee is comprised of both fixed and transaction based fees that provide standalone value and are recognized as incurred. From time-to-time, we may provide discounts on set-up fees; however it is not possible to allocate the discount on the set-up fees because the contract period is unknown and the complete value of the deliverables is unknown. Variables preventing allocation include the variability of the recurring revenue due to transaction levels and the ability of customers to cancel the contract upon 30 days’ notice. If estimation of the customer relationship became necessary, we would rely on the existing customer relationship period that set-up fees are currently being recognized over, resulting in no change in the revenues recognized.

Stock-Based Compensation

We recognize the cost of all share-based payments to employees, including grants of employee stock options, in the financial statements based on the grant date fair value of those awards. This cost is recognized over the period for which an employee is required to provide service in exchange for the award. Benefits associated with tax deductions in excess of recognized compensation expense are reported as a cash flow from financing activities.

We estimate the fair value of options granted using the Black-Scholes option pricing model. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results differ from our estimates, such amounts will be recorded as an adjustment in the period estimates are revised. In valuing share-based awards, significant judgment is required in determining the expected volatility of common stock and the expected term individuals will hold their share-based awards prior to exercising. Expected volatility of the stock is based on a peer group in the industry in which we do business because we do not have sufficient historical volatility data for our own common stock. The expected term of the options is based on the simplified method which does not consider historical or expected employee exercise behavior.

Advertising Costs

Advertising costs are charged to expense as incurred. Advertising costs were approximately $93,000, $94,000 and $56,000 for the years ended December 31, 2011, 2010 and 2009, respectively. Advertising costs are included in operating expenses in our consolidated statements of operations.

Income Taxes

We account for income taxes using the liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance to the extent that utilization is not presently more likely than not.

We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

Net Income per Share

Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, such as options, warrants and redeemable convertible preferred stock. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.

Recent Accounting Pronouncements

In October 2009, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2009-13, Revenue Recognition (ASC Topic 605), Multiple-Deliverable Revenue Arrangements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the fair value requirements of ASC subtopic 605-25, Revenue Recognition-Multiple Element Arrangements, by allowing the use of the “best estimate of selling price” in addition to Vendor Specific Objective Evidence (“VSOE”) and third-party evidence (“TPE”) for determining the selling price of a deliverable. A vendor is now required to use its best estimate of the selling price when VSOE or TPE of the selling price cannot be determined. In addition, the residual method of allocating arrangement consideration is no longer permitted.

In October 2009, the FASB issued ASU No. 2009-14, Software (ASC Topic 985), Certain Revenue Arrangements That Include Software Elements, a consensus of the FASB Emerging Issues Task Force. This guidance modifies the scope of ASC subtopic 965-605, Software-Revenue Recognition, to exclude from its requirements (a) non-software components of tangible products and (b) software components of tangible products that are sold, licensed or leased with tangible products when the software components and non-software components of the tangible product function together to deliver the tangible product’s essential functionality.

ASU No. 2009-13 and ASU No. 2009-14 both require expanded qualitative and quantitative disclosures and are effective for fiscal years beginning on or after June 15, 2010. We have adopted these updates and they did not have a material impact on our financial statements.

In December 2010, the FASB issued ASU No. 2010-29, Business Combinations (ASC Topic 805), Disclosure of Supplementary Pro Forma Information for Business Combinations. ASU No. 2010-29 amends the disclosure requirements for supplementary pro forma information for business combinations. This update addresses the diversity in practice about the interpretation of the pro forma revenue and earnings disclosure requirements for business combinations. The update specifies that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. It also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. This update is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. We have adopted this update and, with the acquisition of Direct EDI in May 2011, the required supplementary pro forma information is presented in Note B.

Acquisition of Direct EDI

12 Months Ended

Dec. 31, 2011

Acquisition of Direct EDI [Abstract]

Acquisition of Direct EDI

NOTE B — Acquisition of Direct EDI

On May 17, 2011, we entered into an asset purchase agreement with Direct EDI LLC, a privately-held provider of cloud-based integration solutions for electronic data interchange, and we completed the asset purchase on May 18, 2011. Under the asset purchase agreement, we purchased and acquired substantially all of the assets of Direct EDI for $10.8 million in cash and assumed certain liabilities of Direct EDI. The acquisition of Direct EDI allows us to expand our base of recurring revenue customers.

Purchase Price Allocation

We accounted for the acquisition as a business combination. We allocated the purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. We engaged an independent third-party valuation firm to assist us in the determination of the value of the purchased intangible assets. The excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. Goodwill is attributed to a trained workforce and other buyer-specific value resulting from expected synergies, including long-term cost savings that are not included in the fair values of assets. Goodwill will not be amortized; however it is deductible for tax purposes. During the fourth quarter of 2011, we completed our evaluation of the purchase price allocation and recorded a purchase price adjustment of approximately $25,000 related to working capital.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands):


Current assets	$	195
Property and equipment		42
Intangible assets		6,120
Goodwill		4,688
Current liabilities		(204	)

Total purchase price	$	10,841

Purchased Intangible Assets

The following table summarizes the estimated fair value of the purchased intangible assets and their estimated useful lives:


Purchased Intangible Assets	Estimated Fair Value (in thousands)		Estimated Life (in years)
Subscriber relationships	$	5,250		7
Non-competition agreements		870		3

Total	$	6,120

The purchased intangible assets are being amortized on a straight-line basis over their estimated useful lives. Amortization expense related to these intangible assets was $643,000 for the year ended December 31, 2011.

Acquisition-Related Costs and Post-Acquisition Operating Results

Acquisition-related costs were approximately $232,000 and are included in general and administrative expense in our consolidated statements of operations for the year ended December 31, 2011. The operating results of Direct EDI have been included in our consolidated financial statements from May 18, 2011, the date of the acquisition. For the year ended December 31, 2011, approximately $2.7 million of our revenues were derived from Direct EDI customers. The amount of operating income or loss from Direct EDI was not separately identifiable due to our integration.

Unaudited Pro Forma Financial Information

The unaudited pro forma financial information in the table below presents the combined operating results of SPS Commerce and Direct EDI as if the acquisition had occurred on January 1, 2010. The unaudited pro forma information includes the historical operating results of each company and certain pro forma adjustments, including annual amortization expense for purchased intangible assets of approximately $1.0 million and additional annual compensation expense of approximately $280,000 related to employment arrangements entered into as part of the acquisition.


	Year Ended December 31,
	2011		2010
	(in thousands, except per share data)
Pro forma total revenue	$	59,815	$	48,746
Pro forma net income		13,576		2,299
Pro forma net income per share
Basic		1.14		0.29
Diluted		1.07		0.20

The unaudited pro forma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that would have actually been reported had the acquisition occurred on January 1, 2010, nor is it necessarily indicative of our results of operations for any future periods.

- Definition

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

Fair Value of Financial Instruments

Fair Value of Financial Instruments [Abstract]

Fair Value of Financial Instruments

NOTE D — Fair Value of Financial Instruments

Fair value represents the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair value:

•

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

•

Level 2 — observable inputs other than quoted prices in active markets for identical assets and liabilities.

•

Level 3 — unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions.

We previously had warrants outstanding to purchase 68,201 shares of our Series B redeemable convertible preferred stock. With the completion of our initial public offering in April 2010, these warrants were converted into warrants to purchase common stock and the related liability was transferred to additional paid-in capital in our consolidated balance sheets. See Note G for additional information. The table below presents a reconciliation of these preferred stock warrants, which were measured at fair value on a recurring basis using significant unobservable inputs (Level 3 inputs) (in thousands):


Balance at January 1, 2010	$	569
Total losses recognized		27
Converted into warrants to purchase common stock and liability transferred to additional paid-in capital		(596	)

Proceeds from the credit facility are anticipated to be used for acquisitions and our capital needs.

Interest on amounts borrowed under the credit facility is based on (i) an Adjusted LIBO Rate (as defined in the revolving credit agreement) plus an applicable margin of 175 to 225 basis points based on our net working capital, or (ii) JPMorgan’s prime rate (provided it is not less than the Adjusted One Month LIBO Rate (as defined in the revolving credit agreement)) plus an applicable margin of -25 to 25 basis points based on our net working capital. Interest is payable monthly in arrears. Availability under the credit facility is subject to a borrowing base equal to the sum of 250% of our eligible monthly recurring revenue (as defined in the revolving credit agreement) and all borrowings are due in full no later than the maturity date of the agreement.

The revolving credit agreement contains customary representations, warranties, covenants and events of default, including, but not limited to financial covenants requiring us to maintain a fixed charge coverage ratio of not less than 1.20 to 1.00, cash and cash equivalents of not less than $10 million and a minimum number of recurring revenue customers. If an event of default occurs, among other things, the applicable interest rate is subject to an increase of 2% and all outstanding obligations may become immediately due and payable.

There were no borrowings under the revolving credit agreement during 2011. As of December 31, 2011, there were no borrowings outstanding and approximately $11.6 million was available for borrowings. We were in compliance with all covenants under the revolving credit agreement as of that date.

Redeemable Convertible Preferred Stock and Stockholders' Equity (Deficit) [Abstract]

Redeemable Convertible Preferred Stock and Stockholders' Equity (Deficit)

NOTE G — Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit)

Reverse Stock Split

On April 13, 2010, we effected a 0.267 for 1 reverse stock split in the form of a combination of our outstanding stock. All share and per share amounts in the accompanying financial statements and notes have been retroactively adjusted for all periods presented to give effect to the reverse stock split.

Initial Public Offering

On April 27, 2010, we completed our initial public offering of 4,711,198 shares of common stock at an offering price of $12.00 per share. We issued and sold 3,114,504 shares, including 614,504 shares sold pursuant to the exercise in full of the underwriters’ over-allotment option, and the selling stockholders sold 1,596,694 shares. We received proceeds of approximately $33.0 million, after payment of underwriting discounts and commissions and legal, accounting and other fees incurred in connection with the offering. On April 30, 2010, approximately $555,000 of the net proceeds was used to repay principal and interest on certain outstanding equipment loans.

At the close of the initial public offering, our previously outstanding shares of redeemable convertible preferred stock were automatically converted into 8,093,826 shares of common stock and warrants to purchase 68,201 shares of redeemable convertible preferred stock were converted into warrants to purchase 68,201 shares of common stock. Accordingly, the related warrant liability of approximately $596,000 was transferred to additional paid-in capital in our consolidated balance sheet. These common stock warrants have an exercise price of $3.67 per share and expiration dates ranging from May 2011 to February 2016.

Secondary Stock Offering

On December 3, 2010, we completed a secondary stock offering of 3,301,926 shares of common stock at an offering price of $12.25 per share. We issued and sold 115,000 shares, including 15,000 shares sold pursuant to the exercise in full of the underwriters’ over-allotment option, and the selling stockholders sold 3,186,926 shares. We received proceeds of approximately $1.0 million after payment of underwriting discounts and commissions and legal, accounting and other fees incurred in connection with the offering.

Preferred Stock Warrants

As discussed above, we previously had warrants outstanding to purchase 68,201 shares of our Series B redeemable convertible preferred stock. These warrants had an exercise price of $3.67 per share and expiration dates ranging from May 2011 to February 2016. We classified these outstanding warrants as a liability in our consolidated balance sheets. These warrants were subject to revaluation at each balance sheet date and any change in fair market value was recognized as a component of other income (expense) in our consolidated statements of operations.

Prior to the conversion of the preferred stock warrants into common stock warrants, we recorded other expense of $27,000 and $381,000 for the years ended December 31, 2010 and 2009, respectively, for changes in the fair market value of these warrants.

Redeemable Convertible Preferred Stock

As discussed above, we previously had issued various classes of redeemable convertible preferred stock. The holders of our Series A, B, and C redeemable convertible preferred stock had the option to put their shares back to the company at the liquidation preference value, as defined in the Certificate of Incorporation, in the event of any liquidation, dissolution or winding up of the company, as defined.

None of the Series A, B and C redeemable convertible preferred stock had a mandatory redemption feature. In the event of a liquidation, as defined, the holders of Series C redeemable convertible preferred stock were entitled to receive, prior to and in preference to any distribution of any assets or surplus funds of the company to the holders of Series A and B redeemable convertible preferred stock or common stock, an amount in cash equal to $5.99 per share plus accrued unpaid dividends. After the liquidation payment to Series C redeemable convertible preferred stockholders, the holders of Series B redeemable convertible preferred stock were entitled to receive, prior to and in preference to any distribution of any assets or surplus funds of the company to the holders of Series A redeemable convertible preferred stock or common stock, an amount in cash equal to $3.67 per share plus accrued unpaid dividends. After the liquidation payment of Series B redeemable convertible preferred stockholders, the holders of Series A redeemable convertible preferred stock were entitled to receive, prior to and in preference to any distribution of any assets or surplus funds of the company to the holders of common stock, an amount in cash equal to $8.65 per share plus accrued unpaid dividends. After the liquidation payment to Series A, B and C redeemable convertible preferred stockholders, holders of common stock and Series A, B and C redeemable convertible preferred stock would share pro rata in the remaining assets of the company.

Each share of Series A, B, and C redeemable convertible preferred stock, at the option of the holder, was convertible into common shares at a conversion ratio equal to the conversion value divided by the conversion price. The conversion ratio was 1 to 1 at December 31, 2009. The conversion value and conversion price were initially set in our Fifth Amended and Restated Certificate of Incorporation at $8.65, $3.67 and $5.99 for the Series A, B and C redeemable convertible preferred stock, respectively. The conversion price was subject to adjustment for certain dilutive issuances. We had not issued any dilutive instruments which would adjust the conversion price and, therefore, the conversion value and the conversion price had not changed since they were initially set.

Each share of Series A, B and C redeemable convertible preferred stock were to be automatically and immediately converted into shares of common stock upon the closing of a public offering pursuant to an effective registration statement at the then effective conversion ratio, if the offering price per share was not less than $13.45 and the gross proceeds to the company were at least $20,000,000. Each share of redeemable convertible preferred stock was subject to weighted-average anti-dilution price protection. The holders of the redeemable convertible preferred stock were entitled to dividends only when declared. No dividends had been declared since the issuance of the redeemable convertible preferred stock. The holders of Series A, B and C redeemable convertible preferred stock were generally entitled to vote on all matters submitted to a vote of stockholders, except those required by law to be submitted to a class vote.

Stock-Based Compensation

12 Months Ended

Stock-Based Compensation [Abstract]

Stock-Based Compensation

NOTE H — Stock-Based Compensation

Our equity compensation plans provide for the grant of incentive and nonqualified stock options, as well as other stock-based awards, to employees, non-employee directors and other consultants who provide services to us. Stock options generally vest over three to four years and have a contractual term of ten years from the date of grant. During 2011, approximately 711,000 additional shares were authorized under our 2010 Equity Incentive Plan as available for grant and, at December 31, 2011, there were approximately 660,000 shares available for grant under approved equity compensation plans. Each award exercised results in the issuance of new shares.

We recorded non-cash stock-based compensation expense of $1.8 million, $750,000 and $228,000 for the years ended December 31, 2011, 2010 and 2009, respectively. This expense was allocated as follows (in thousands):


	Year Ended December 31,
	2011		2010		2009
Cost of revenues	$	255	$	103	$	46
Operating expenses
Sales and marketing		471		211		91
Research and development		56		20		4
General and administrative		986		416		88

Total stock-based compensation expense	$	1,768	$	750	$	229

As of December 31, 2011, there was approximately $4.3 million of unrecognized stock-based compensation expense under our equity compensation plans, which is expected to be recognized on a straight line basis over a weighted average period of approximately 2 years.

Our stock option activity was as follows:


	Options (#)			Weighted Average Exercise Price ($/share)
Outstanding at January 1, 2009		1,187,583		$	2.69
Granted		339,187			2.86
Exercised		(15,640	)		0.37
Forfeited		(262,925	)		7.98

Outstanding at December 31, 2009		1,248,205			1.65
Granted		479,691			11.87
Exercised		(157,056	)		0.82
Forfeited		(21,496	)		23.92

Outstanding at December 31, 2010		1,549,344			4.59
Granted		431,790			17.04
Exercised		(289,286	)		2.15
Forfeited		(22,439	)		11.38

Outstanding at December 31, 2011		1,669,409			8.14

Of the total outstanding options at December 31, 2011, 955,342 were exercisable with a weighted average exercise price of $3.23 per share. The total outstanding options had a weighted average remaining contractual life of 6.2 years.

The fair value of options vested during the years ended December 31, 2011, 2010 and 2009 was $1.3 million, $200,000 and $228,000, respectively.

The intrinsic value of options exercised during the years ended December 31, 2011, 2010 and 2009 was $4.9 million, $1.7 million and $101,000, respectively. The intrinsic value of outstanding options was $29.7 million, $17.4 million and $12.9 million at December 31, 2011, 2010 and 2009 respectively.

The weighted-average fair values per share of options granted during 2011, 2010 and 2009 were $8.25, $5.82 and $1.54, respectively. The fair value of the options granted was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:


	2011	2010	2009
Weighted-average volatility	45%	46% - 49%	49% - 53%
Expected dividend yield	—	—	—
Expected life (in years)	6.25	6.25	4.0 - 7.0
Weighted-average risk-free interest rate	1.58% - 3.05%	1.79% - 3.14%	2.71% - 4.01%

Prior to becoming a public entity in 2010, historic volatility was not available for our shares. As a result, we estimated volatility based on a peer group of companies, which collectively provided a reasonable basis for estimating volatility. We intend to continue to consistently use the same group of publicly traded peer companies to determine volatility in the future until sufficient information regarding volatility of our share price becomes available or the selected companies are no longer suitable for this purpose.

We have not issued dividends on our common stock and do not expect to do so in the foreseeable future. The expected term of the options is based on evaluations of historical and expected future employee exercise behavior. The estimated pre-vesting forfeiture rate is based on our historical experience. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date.

Income Taxes [Abstract]

Income Taxes

NOTE I — Income Taxes

The provision (benefit) for income taxes was as follows (in thousands):


	Year Ended December 31,
	2011			2010		2009
Current
Federal	$	—		$	41	$	36
State		89			23		27
Deferred
Federal		(12,282	)		26		26
State		(426	)		2		2

	$	(12,619	)	$	92	$	91

Our provision (benefit) for income taxes includes state income and franchise taxes and the release of a substantial portion of the valuation allowance on our deferred tax assets. The release of the valuation allowance is a non-cash event that indicates we expect the probability is more likely than not that we will generate sufficient future profits to fully utilize our deferred tax assets.

A reconciliation of the provision (benefit) for income taxes to the statutory federal rate was as follows (in thousands):


	Year Ended December 31,
	2011			2010			2009
Expected federal income tax at statutory rate	$	396		$	1,013		$	420

Total provision (benefit) for income taxes	$	(12,619	)	$	92		$	91

As of December 31, 2011, we had an income tax receivable of $90,000, which is included in prepaid expenses and other current assets in the consolidated balance sheets.

As of December 31, 2011, we had net operating loss carryforwards of $51.1 million for U.S. federal tax purposes and $22.5 million of various state net operating loss carryforwards. Our net operating loss carryforwards will expire between 2012 and 2031 if not utilized.

Section 382 of the U.S. Internal Revenue Code generally imposes an annual limitation on the amount of net operating loss carryforwards that might be used to offset taxable income when a corporation has undergone significant changes in stock ownership. We have performed a Section 382 analysis for the time period from our inception through December 8, 2010. During this time period it was determined that we had six separate ownership changes under Section 382. We have not updated the Section 382 analysis subsequent to December 8, 2010; however, we believe there have not been any events subsequent to that date that would impact the analysis. We believe that approximately $17.6 million of federal losses and $13.0 million of state losses will expire unused due to Section 382 limitations. The maximum annual limitation of federal net operating losses under Section 382 is approximately $990,000. The limitation could be further restricted if ownership changes occur in future years.

Our federal and state net operating losses at December 31, 2011 include $5.9 million and $0.9 million, respectively, of income tax deductions in excess of previously recorded tax benefits. Although these additional tax deductions are included in the net operating losses referenced above, the related tax benefit will not be recognized until the deductions reduce our income taxes payable. The tax benefit of these excess deductions will be reflected as a credit to additional paid in capital when recognized. Accordingly, our deferred tax assets are reported net of the excess tax deductions for stock compensation and Section 382 limitations.

Realization of our net operating loss carryforwards and other deferred tax temporary differences are contingent upon future taxable earnings. We assess our ability to realize our deferred tax assets on a regular and periodic basis. Based on our assessments prior to the fourth quarter of 2011, we had provided full valuation allowances against all of our deferred tax assets. The valuation allowances had been provided because our management determined that it was more-likely-than-not that we would not realize these deferred tax assets, largely due to our history of taxable losses since inception.

Based on our assessment during the fourth quarter of 2011, we determined that it was more-likely-than-not that we would be able to realize $12.8 million of our deferred tax assets, which enabled us to release a substantial portion of the valuation allowance previously recorded. This determination was based on weighing both the positive and negative evidence available including, but not limited to, our earnings history, our projected future taxable income, our business strategy and the nature of each of our deferred tax assets. The remaining valuation allowance of $369,000 relates to various state net operating loss carryforwards, state credit carryforwards and foreign net operating loss carryforwards that we do not expect to utilize.

The assessment of our valuation allowance against our deferred tax assets requires significant judgment. If our estimates of future taxable income vary from actual results, our assessment regarding the realization of our deferred tax assets could change. Future changes in the estimated amount of deferred taxes that are expected to be realized will be reflected in our consolidated financial statements in the period the estimate is changed, with a corresponding adjustment to our operating results.

The significant components of our deferred tax assets (liabilities) were as follows (in thousands):


	December 31,
	2011			2010
Current
Current net operating loss and credit carryforwards	$	856		$	—
Accounts receivable allowance		126			115
Accrued expenses		390			346

Total current deferred tax asset		1,372			461

Deferred operations		(589	)		(315	)

Total current deferred tax liability		(589	)		(315	)

Valuation allowance		—			(146	)

Net current deferred tax asset	$	783		$	—

Non-current
Net operating loss and credit carryforwards	$	9,342		$	12,636
Deferred operations		1,413			1,116
Stock option expense		718			—
Depreciation and amortization		672			444
Other		11			—

Total non-current deferred tax asset		12,156			14,196
Valuation allowance		(369	)		(14,334	)

Net non-current deferred tax asset	$	11,787		$	(138	)

We are subject to income taxes in the U.S. federal and various state and international jurisdictions. We are generally subject to U.S. federal and state tax examinations for all tax years since 1995 due to our net operating loss carryforwards and the utilization of the carryforwards in years still open under statute. As of December 31, 2011 we are not under any income tax audits by tax authorities.

As of December 31, 2011, we do not have any unrecognized tax benefits. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We do not expect any material changes in our unrecognized tax positions over the next 12 months.

- Definition

On February 14, 2012, we executed a new lease agreement for our current headquarters location which commences on November 1, 2012 and expires on April 30, 2020. The lease includes additional square footage upon commencement, an automatic expansion of space on or about September 1, 2013, a right of first offer to lease certain additional space, and two options to extend the term of the lease for three years at a market rate determined in accordance with the lease. In connection with this new lease, we will deliver to the landlord cash or an irrevocable letter of credit for approximately $172,000, subject to increase based on square footage expansion, as security for performance of our obligations under the lease.
