Basis of Presentation and Significant Accounting Policies	'
	NOTE 2—Basis of Presentation and Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of Ellie Mae and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
	Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on revenues, income from operations or net income as previously reported.
	Applicable Accounting Guidance
	Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative generally accepted accounting principles in the United States (“U.S. GAAP”), as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. 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 period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, other intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s consolidated financial statements and footnotes.
	Cash and Cash Equivalents
	All highly liquid investments with original maturities of 90 days or less are considered to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value.
	Fair Value of Financial Instruments
	The fair values of the Company’s cash and cash equivalents, accounts receivable, notes receivable and accounts payable approximate their carrying values due to the short maturities of the instruments. The fair value of the Company’s capital lease obligations approximates the carrying value due to the short-term maturities of the leases.
	All of the Company’s investments that have maturities of greater than 90 days are classified as available-for-sale and are carried at fair value. The Company invests excess cash primarily in investment-grade interest-bearing securities such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government, all of which are subject to minimal credit and market risks. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. The cost of available-for-sale marketable securities sold is based on the specific identification method. Unrealized gains and losses, net of tax, are reported in stockholders’ equity as accumulated other comprehensive loss. Realized gains and losses are included in other income (expense), net. Interest and dividends are included in other income (expense), net when they are earned.
	Allowance for Doubtful Accounts
	The Company analyzes individual trade accounts receivable by considering historical bad debts, customer creditworthiness, current economic trends, changes in customer payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Allowances for doubtful accounts are recognized in the period in which the associated receivable balance is not considered recoverable. Any change in the assumptions used in analyzing accounts receivable may result in changes to the allowance for doubtful accounts and is recognized in the period in which the change occurs. The Company writes off a receivable when all rights, remedies and recourses against the account and its principals are exhausted and records a benefit when previously reserved accounts are collected.
	Concentration of Credit Risk
	The financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. The Company’s cash and cash equivalents are deposited with major financial institutions in the United States. At times, such deposits may be in excess of insured limits. Management believes that the Company’s investments in cash equivalents and available-for-sale investments are financially sound and have minimal credit risk. The Company’s accounts receivable are derived from revenue earned from customers located in the United States. The Company had no customers that represented 10% or more of revenues for the years ended December 31, 2013, 2012 and 2011. No customer represented more than 10% of accounts receivable as of December 31, 2013 and 2012.
	Software and Website Development Costs
	The Company capitalizes internal and external costs incurred to develop internal-use software and website applications. Capitalized internal costs include salaries, benefits and stock-based compensation charges for employees that are directly involved in developing the software or website application, and depreciation of assets used in the development process. Capitalized external costs include third-party consultants involved in the development process, as well as other direct costs incurred as part of the development process.
	Capitalization of costs begins when the preliminary project stage is completed, and management authorizes and commits to funding a project and it is probable that the project will be completed and the software or website application will be used to perform the function intended. Internal and external costs incurred as part of the preliminary project stage are expensed as incurred.
	Capitalization ceases at the point at which the project is substantially complete and ready for its intended use, after all substantial testing is completed. Internal and external training costs and maintenance costs during the post-implementation operation stage are expensed as incurred.
	Internal-use software is amortized on a straight-line basis over its estimated useful life, generally three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The capitalized costs are included in “Property and equipment, net” in the accompanying consolidated balance sheets. For the years ended December 31, 2013 and 2012, the Company capitalized software and website application development costs of $5.0 million and $0.5 million, respectively. There were no such costs capitalized in the year ended December 31, 2011. There was $69,000 in amortization of capitalized internal-use software and website development costs recorded during the year ended December 31, 2013 and no such amortization recorded during the years ended December 31, 2012 and 2011.
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over their estimated useful lives, which is generally three years. Leasehold improvements are amortized over the shorter of the asset’s useful life or term of the lease.
	Business Combinations
	The Company recognizes and measures the identifiable assets acquired in a business combination, the liabilities assumed and any non-controlling interest in the acquiree, measured at their fair values as of the acquisition date. Under ASC 805, the Company recognizes contingent consideration arrangements at their acquisition-date fair values with subsequent changes in fair value reflected in earnings, recognizes pre-acquisition loss and gain contingencies at their acquisition-date fair values (with certain exceptions), capitalizes in-process research and development assets, expenses acquisition-related transaction costs as incurred, and limits the capitalization of acquisition-related restructuring as of the acquisition date. Due to the inherent uncertainty in the Company’s best estimates and assumptions, they are subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any subsequent adjustments, including changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period, are recognized in earnings rather than as an adjustment to the cost of the acquisition.
	Goodwill
	The Company records goodwill in a business combination when the consideration paid exceeds the fair value of the net assets acquired. Goodwill is not amortized, but is tested for impairment at least annually in the fourth quarter of the Company’s fiscal year, or whenever changes in circumstances indicate that the fair value of a reporting unit is less than its carrying amount, including goodwill. The annual test is performed at the reporting unit level using a fair-value based approach. The Company’s operations are organized as one reporting unit. In testing for a potential impairment of goodwill, the Company first compares the carrying value of assets and liabilities to the estimated fair value. If estimated fair value is less than carrying value, then potential impairment exists. The amount of any impairment is then calculated by determining the implied fair value of goodwill using a hypothetical purchase price allocation. Impairment is equivalent to any excess of goodwill carrying value over its implied fair value.
	The process of evaluating the potential impairment of goodwill requires significant judgment at many points during the analysis, including calculating fair value of each reporting unit based on estimated future cash flows and discount rates to be applied.
	The Company completed its annual impairment tests during the fourth quarters of 2013, 2012 and 2011 and determined that goodwill was not impaired.
	Other Intangible Assets
	Other intangible assets are stated at cost less accumulated amortization. Other intangible assets include developed technology, trade names and customer lists and contracts. Intangible assets with finite lives are amortized on a straight-line basis over the estimated periods of benefit, as follows:
	Developed technology	3-5 years
	Trade names	3 years
	Customer lists and contracts	1-9 years
	The Company evaluates its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to future undiscounted net cash flows expected to be generated by the asset group. If such assets are considered to be impaired, the impairment loss to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount and fair value less costs to sell. There have been no such impairments of finite-lived intangible assets for the years ended December 31, 2013, 2012 and 2011.
	Impairment of Long-Lived Assets
	The Company evaluates its long-lived assets for indications of possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. There has been no such impairment of long-lived assets for the years ended December 31, 2013, 2012 and 2011.
	Revenue Recognition
	The Company generates revenue primarily from on-demand and on-premise fees for software and related services. On-demand revenues are revenues generated from company-hosted software subscriptions that customers access through the Internet as well as revenues from a small number of customers that have opted to self-host a portion of the software but pay fees based on a per closed loan, or success, basis subject to monthly base fees, which the Company refers to as Success-Based Pricing. On-demand revenues are also comprised of software services sold transactionally and Ellie Mae Network transaction fees. On-premise revenues are revenues generated from maintenance services, sales of customer-hosted software licenses (except for customer-hosted Success-Based Pricing revenues, which are included in on-demand revenues described above), and professional services, which include consulting, implementation and training services. Sales taxes assessed by governmental authorities are excluded from revenue.
	The Company commences revenue recognition when all of the following conditions are satisfied:
	•There is persuasive evidence of an arrangement
	•The service has been or is being provided to the customer
	•The collection of the fees is reasonably assured; and
	•The amount of fees to be paid by the customer is fixed or determinable.
	On-Demand Revenues
	Subscription Services and Usage-Based Fee Arrangements. Subscription services and usage-based fee arrangements generally include a combination of the Company’s products delivered as software-as-a-service (“SaaS”) and support services. These arrangements are non-cancelable and do not contain refund-type provisions. These revenues generally include the following:
	SaaS Encompass Revenues. The Company offers web-based, on-demand access to Encompass for a monthly recurring fee. The Company provides the right to access its loan origination software and handles the responsibility of managing the servers, providing security, backing up the data and applying updates; however, except where customers self-host a portion of the software in a Success-Based Pricing structure, customers under SaaS arrangements may not take possession of the software at any time during the term of the agreement. Subscription revenues are recognized ratably over the contract terms beginning on the commencement date of each contract, which is the date the Company’s service is made available to customers. Contracts generally range from one year to five years.
	Alternatively, customers can elect to pay on a per closed loan, or success, basis. Success basis contracts generally have a term of one to five years and are subject to monthly base fees, which enable customers to close loans up to a contractually agreed-to minimum number of transactions, and additional closed loan fees, which are assessed for loans closed in excess of the minimum. Revenue is earned from both base fees and additional closed loan fees as the result of the customer’s usage of Encompass. Monthly base fees are recognized over the respective monthly service period as the software is utilized. Additional closed loans fees are recognized when the loans are reported as closed. This offering also includes Encompass CenterWise, Encompass Compliance Service and Encompass Docs Solution for Encompass as integrated components, which are combined elements of the arrangement that is delivered in conjunction with the SaaS Encompass offering and therefore is not accounted for separately.
	Encompass CenterWise Revenues. Encompass CenterWise is a bundled offering of electronic document management (“EDM”) and websites used for customer relationship management. Generally, revenue is recognized for Encompass CenterWise after the service is rendered, except when Encompass CenterWise is automatically included as an integrated component of the SaaS Encompass offering, in which case the associated revenue is recognized as described above.
	Services Revenues. The Company provides mortgage-related and other business services, including automated documentation preparation and compliance reports. Services revenues are recognized after the services are rendered.
	Transaction Revenues. The Company has entered into agreements with various lenders, service providers and certain government agencies participating in the mortgage origination process that provide them access to, and ability to interoperate with, mortgage originators on the Ellie Mae Network. Under these agreements, the Company earns transaction fees when transactions are processed through the Ellie Mae Network. Transaction revenues are recognized when there is evidence that the qualifying transactions have occurred on the Ellie Mae Network and collection of the resulting receivable is reasonably assured.
	On-Premise Revenues
	With the exception of revenue from customers that self-host a portion of the software in a Success-Based Pricing structure (which is recognized as described above), revenue from the sale of software licenses is recognized in the month in which the required revenue recognition criteria are met, generally in the month in which the software is delivered. Revenue from the sale of maintenance services and professional services is recognized over the period in which the services are provided.
	Multiple Element Arrangements
	The Company has entered into both subscription services and software arrangements with multiple elements. When subscription services involve multiple elements that qualify as separate units of accounting, the Company allocates arrangement consideration at the inception of an arrangement to all deliverables based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) if it is available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) the best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE. The Company determines VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range. The Company has not historically priced its subscription services within a narrow range. As a result, the Company has not been able to establish selling prices for subscription services based on VSOE.
	TPE. When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services’ selling prices are on a standalone basis. As a result, the Company has not been able to establish selling prices based on TPE.
	BESP. When the Company is unable to establish a selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service was sold on a standalone basis. When establishing BESP, the Company reviews company specific factors used to determine list price and makes adjustments as appropriate to reflect current market conditions and pricing behavior. The Company’s process for establishing list price includes assessing the cost to provide a particular product or service, surveying customers to determine market expectations, analyzing customer demographics and taking into account similar products and services historically sold by the Company. The Company continues to review the factors used to establish list price and adjusts BESP as necessary.
	Because the Company has determined that neither VSOE nor TPE is available, it uses BESP to allocate the selling price to multiple elements in subscription services arrangements. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
	In order to treat deliverables in a multiple-deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery. Subscription services have standalone value as such services are often sold separately. Additionally, the Company has concluded that professional services have standalone value. In establishing standalone value, the Company considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, and the timing of when the professional services contract was signed in comparison to the subscription service start date.
	For software arrangements with multiple elements (e.g., undelivered maintenance and support contracts bundled with licenses), revenue is allocated to the delivered elements of the arrangement when VSOE is determinable, using the residual value method based on objective evidence of the fair value of the undelivered elements, which is specific to the Company. When VSOE is not determinable, the entire arrangement is recognized ratably over the term of the contract. Revenue is recognized under this model upon receipt of cash payment from the customer if collectability is not reasonably assured and when other revenue recognition criteria have been met. The VSOE of fair value for maintenance and support obligations related to licenses is based upon the prices paid for the separate renewal of these services by the customer. Maintenance revenues are recognized ratably over the period of the maintenance contract.
	Deferred Revenue
Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. Balances consist primarily of maintenance and professional services not yet provided as of the balance sheet date. Deferred revenue that will be recognized during the succeeding 12 month period is recorded as current deferred revenue, and the remaining portion is recorded as other long-term liabilities.
Deferred Commission Expense
Deferred commission expenses are the incremental costs that are directly associated with non-cancelable subscription contracts with customers and consist of sales commissions paid to our direct sales force. Commissions are calculated based on a percentage of the revenues for the non-cancelable term of subscription contracts, which are typically one to five years.
Prior to 2013, commissions were paid and recognized as sales expense when customer payments for contracted services were received on a monthly basis because commissions were earned based on receipt of customer payments. In 2013, we amended our commission plans to provide for payment after the customer's contract is signed. As a result of the change in commission plans, beginning in 2013, commission expense is deferred and amortized to sales expense over the non-cancelable terms of the related subscription contracts. The deferred commission expense amounts are recoverable through the future revenue streams under the non-cancelable customer contracts. The new plans also include claw back provisions, which require repayment of a proportionate amount of commissions, should customers cancel their contracts prior to the end of the initial contractual term.
During year ended December 31, 2013, we deferred $1.9 million of commission expense, of which $1.6 million remained on our consolidated balance sheets at December 31, 2013. No amounts were deferred as of December 31, 2012.
Warranties and Indemnification
The Company provides a warranty for its software products and services to its customers and accounts for its warranties as a contingent liability. The Company’s software is generally warranted to perform substantially as described in the associated product documentation. The Company’s services are generally warranted to be performed consistent with industry standards. If there is a failure of such warranties, the Company generally is obligated to repair or replace the product or service or correct it to conform to the warranty provision. If the Company is unable to do so, the customer is entitled to terminate the agreement with the Company. With respect to Encompass Compliance Service, the Company provides a limited warranty, which limits its liability to the reimbursement for losses incurred by a customer due to fines, penalties or judgments imposed or levied upon a customer as a result of a violation of a specific law, rule or regulation resulting from an error in the provision of the Company’s Encompass Compliance Service. The Company’s maximum exposure is limited under its services agreements to the greater of the total service fees paid by a customer for such services during the specified period preceding the relevant claim, typically six to 12 months, or a specified dollar amount ranging from $50,000 to $5.0 million. The Company has not historically incurred any significant claims and maintains a total of $10.0 million in professional liability insurance coverage. The Company has not provided for a warranty accrual as of December 31, 2013 or 2012. To date, the Company’s product warranty expense has not been significant.
The Company generally agrees to indemnify its customers against legal claims that the Company’s software products infringe certain third-party intellectual property rights and accounts for its indemnification obligations as a contingent liability. In the event of such a claim, the Company is obligated to defend its customer against the claim and to either settle the claim at the Company’s expense or pay damages that the customer is legally required to pay to the third-party claimant. In addition, in the event of an infringement, the Company agrees to modify or replace the infringing product, or, if those options are not reasonably possible, to refund the cost of the software, as pro-rated over a period of years. To date, the Company has not been required to make any payment resulting from infringement claims asserted against its customers. The Company has not recorded a liability for infringement costs as of December 31, 2013 or 2012.
The Company has obligations under certain circumstances to indemnify each member of the Company’s board of directors against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws and certificate of incorporation.
Cost of Revenues
The Company’s cost of revenues consists primarily of salaries, benefits and related costs (including stock-based compensation), allocated facilities costs, customer support, data centers, expenses for document preparation, income verification and compliance services, depreciation on computer equipment used in supporting the Ellie Mae Network, the Company’s SaaS Encompass and Encompass CenterWise offerings, amortization of acquired intangible assets directly involved in revenue producing activities and professional services associated with implementation of software.
Research and Development Costs
Research and development costs are expensed as incurred.
Advertising Expenses
The Company expenses advertising costs as incurred. Advertising expenses for the years ended December 31, 2013, 2012 and 2011 were $0.4 million, $0.3 million, and $0.3 million, respectively.
Stock-Based Compensation
The Company recognizes stock-based compensation related to awards granted under its 2009 Stock Option and Incentive Plan (the “2009 Plan”), 2011 Equity Incentive Award Plan (the “2011 Plan”) and Employee Stock Purchase Plan (“ESPP”).
The Company recognizes compensation expense related to stock option grants that are ultimately expected to vest based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. Such expense is recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period.
The Company recognizes compensation expense related to restricted awards, restricted stock unit awards (“RSUs”), and performance share awards (“Performance Awards”) based on the fair market value of the underlying shares of common stock as of the date of grant. Expense related to the restricted awards and the RSUs are recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period. Expense related to the Performance Awards is recognized under an accelerated method over the requisite service period of the award, which recognizes a larger portion of the expense during the beginning of the vesting period than in the end of the vesting period. Management estimates the probable number of shares of common stock that will be granted until the achievement of the performance goals is known.
The date of grant is the date at which the Company and the employee reach a mutual understanding of the key terms and conditions of the award, appropriate approvals are received by approval by the board of directors and the Company becomes contingently obligated to issue equity instruments to the employee who renders the requisite service.
The Company is required to estimate potential forfeitures of stock grants and adjust recorded compensation cost accordingly. The estimate of forfeitures is based on historical experience and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in estimated forfeitures will be recognized in the period of change and will impact the amount of stock-based compensation expense to be recognized in future periods.
All stock option awards to non-employees are accounted for at the fair value of the consideration received or the fair value of the equity instrument issued, as calculated using the Black-Scholes option-pricing model. The measurement of stock-based compensation for non-employees is subject to periodic adjustments as the options vest, and the expense is recognized over the period services are rendered.
Other Income (Expense), Net
Other income (expense), net consisted of the following:
	Year ended December 31,

	(in thousands)
Interest income	650		146		159
Net realized loss on investments	(55	)	—		—
Interest expense	(135	)	(189	)	(83	)
Total other income (expense), net	460		(43	)	76
Income Taxes
The Company accounts for income taxes under the asset and liability method, which requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. The Company’s determination of its valuation allowance is based upon a number of assumptions, judgments and estimates, including forecasted earnings, future taxable income and the relative proportions of revenue and income before taxes in the various jurisdictions in which it operates.
The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. Tax positions are based upon their technical merits, relevant tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax positions. A tax position is only recognized in the financial statements if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments that could result in recognition of additional tax benefits or additional charges to the tax provision and may not accurately reflect actual outcomes. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes.
Comprehensive Income
Comprehensive income consists of net income and other comprehensive gain (loss). Other comprehensive gain (loss) includes certain changes in equity that are excluded from net income, specifically unrealized gains and losses on available-for-sale investments. There were no reclassifications out of accumulated other comprehensive income (“AOCI”) that affected net income during the years ended December 31, 2013 and 2012.
Geographical Information
The Company is domiciled in the United States and had no international operations or sales to customers outside of the United States for the years ended December 31, 2013, 2012 and 2011.
Recent Accounting Pronouncements
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Topic 740 - Income Taxes (“ASU 2013-11”) which provides guidance to improve the presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We intend to adopt this standard in the first fiscal quarter of 2014 and do not expect the adoption will have a material impact on our consolidated financial statements.

Earnings Per Share [Abstract]	'
Net Income Per Share of Common Stock	'
	NOTE 3—Net Income Per Share of Common Stock
	Net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted net income per share of common stock is calculated by dividing net income by the weighted average shares of common stock outstanding and potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of stock options, warrants and employee stock purchase plan shares using the treasury stock method, and RSUs, if dilutive.
	The components of net income per share of common stock were as follows:
		Year ended December 31,
		2013			2012			2011
		(in thousands, except share and per share amounts)
	Net income	$	12,576		$	19,464		$	3,620

	Diluted shares:
	Weighted average shares used to compute basic net income per share	26,581,962			23,523,222			15,618,053
	Effect of potentially dilutive securities:
	Employee stock options, RSUs, Performance Awards and ESPP shares	1,920,441			2,013,970			5,031,398
	Weighted average shares used to compute diluted net income per share	28,502,403			25,537,192			20,649,451
	Net income per share:
	Basic	$	0.47		$	0.83		$	0.23
	Diluted	$	0.44		$	0.76		$	0.18
	The following potential common shares were excluded from the computation of diluted net income per share, as their effect would have been anti-dilutive:
		Twelve months ended December 31,
		2013		2012			2011
	Employee stock options and awards	758,900		252,462			1,128,632
	Performance-based awards are included in the diluted shares outstanding for each period if the established performance criteria have been met at the end of the respective periods. However, if none of the required performance criteria have been met for such awards, the Company includes the number of shares that would be issuable if the end of the reporting period were the end of the contingency period. Accordingly, in addition to the shares noted above, 0, 588,000 and 583,333 performance-based shares were excluded from the dilutive shares outstanding for the years ended December 31, 2013, 2012 and 2011, respectively.

Financial Instruments and Fair Value Measurements [Abstract]	'
Financial Instruments and Fair Value Measurements	'
	NOTE 4—Financial Instruments and Fair Value Measurements
	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories:
	Level 1— Valuations based on quoted prices in active markets for identical assets or liabilities.
	Level 2— Valuations based on other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3— Valuations based on inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities.
	The following tables set forth by level within the fair value hierarchy the Company’s financial assets that were accounted for at fair value on a recurring basis, according to the valuation techniques the Company used to determine their values:
		Fair value at		Fair value measurements
				using inputs considered as
		December 31, 2013		Level 1			Level 2			Level 3

	Money market funds	$	16,431	$	16,431		$	—		$	—

		$	96,879	$	41,164		$	55,715		$	—
	Financial instruments include cash, cash equivalents and investments including investment-grade interest-bearing securities such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government. The Company classifies its money market funds that are specifically backed by debt securities and U.S. government obligations as Level 1 instruments due to the use of observable market prices for identical securities that are traded in active markets.
	When we use observable market prices for identical securities that are traded in less active markets, we classify our marketable financial instruments as Level 2. When observable market prices for identical securities are not available, we price our marketable financial instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. We corroborate non-binding market consensus prices with observable market data as such data exists.
	As of December 31, 2013 and December 31, 2012, the Company did not have any assets or liabilities that were valued using Level 3 inputs. For the years ended December 31, 2013, 2012 and 2011, there were no transfers of financial instruments between Level 1, Level 2 or Level 3 classifications.
	For the years ended December 31, 2013, 2012 and 2011, the Company recognized interest income from financial instruments of $2.1 million, $0.2 million and $0.1 million, respectively. Gross realized gains and gross realized losses from the sale of investments were not significant during the years ended December 31, 2013, 2012 and 2011.

	NOTE 5—Acquisitions
	Del Mar Datatrac, Inc.
	On August 15, 2011, the Company entered into a Stock Purchase Agreement and acquired all of the outstanding shares of Del Mar Datatrac, Inc. (“DMD”), a mortgage lending automation business, for a total purchase consideration of $25.1 million in cash, of which $17.2 million was paid at closing and the remaining $8.0 million (“the holdback”), net of $0.1 million measurement period closing settlement adjustments, was to be paid without interest as follows: $3.0 million on August 15, 2012, $3.0 million on August 15, 2013 and $2.0 million on August 15, 2014. The 2012 and 2013 payments were made as scheduled and reduced the acquisition holdback liability on the Company’s consolidated balance sheet.
	Subject to certain exceptions and limitations, the Company and DMD agreed to indemnify each other for breaches of representations, warranties and covenants and other specified matters. The indemnity period expired on February 15, 2013.
	The acquisition was accounted for as a business combination. The operating results of DMD including revenue of $2.5 million and net loss of $1.3 million for the year ended December 31, 2011 were included in the Company’s consolidated financial statements commencing as of the acquisition date of August 15, 2011. In connection with the acquisition, the Company incurred related transaction expenses of approximately $0.4 million which have been recorded in general and administrative expenses in the Company’s consolidated statement of comprehensive income for the year ended December 31, 2011.
	The allocation of the purchase consideration of $25.1 million, net of $0.4 million of imputed interest related to the holdback, to the identifiable tangible and intangible assets acquired and liabilities assumed, based on their estimated fair values as of the acquisition date is summarized in the following table (in thousands):
		(in thousands)
	Current assets (consisting primarily of accounts receivable)	$	521
	Property and equipment	329
	Other long-term assets	31
	Amortizable intangible assets:
	Customer relationships and contracts	4,220
	Maintenance relationships	2,490
	Developed technology	960
	Trade name	230
	Deferred revenue, current	(964		)
	Other current liabilities	(539		)
	Long-term liabilities	(22		)
	Deferred tax liabilities, net	(1,654		)
	Goodwill	19,086
	Total purchase consideration	$	24,688
	Customer relationships and contracts relate to the Company’s ability to sell existing and future versions of the Company’s products and services to existing DMD customers. The fair value of the customer relationships was determined by discounting the estimated net future cash flows from the customer contracts. The Company is amortizing customer relationships and contracts on a straight-line basis over an estimated life of 6 years.
	Maintenance relationships relate to DMD‘s existing maintenance contracts and the Company’s ability to sell existing and future versions of the Company’s products and services to existing DMD customers. The fair value of the maintenance relationships was determined by discounting the estimated net future cash flows from those maintenance customer contracts. The Company is amortizing the assets on a straight-line basis over an estimated life of 9 years.
	Developed technology consists of products which have reached technological feasibility and relate to mortgage lending solutions. The value of the developed technology was determined by discounting the estimated net future cash flows of these products. The Company is amortizing the existing and core technology on a straight-line basis over estimated lives of 3 years.
	Trade name represents various DMD brands, registered product names and marks. The fair value of trade name was determined by estimating a benefit from owning the asset rather than paying a royalty to a third party for the use of the asset. The Company is amortizing the asset on a straight-line basis over an estimated life of 3 years.
	Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets and is not deductible for tax purposes. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets was the acquisition of an assembled workforce of experienced mortgage origination software development engineers, synergies in products, technologies, skill sets, operations, customer base and organizational cultures that can be leveraged to enable the Company to build an enterprise value greater than the sum of its parts.
	Mortgage Pricing System, LLC
	On January 3, 2011, the Company purchased substantially all of the assets of Mortgage Pricing System, LLC (“MPS”), a developer of sophisticated pricing solutions for mortgage lenders. The acquisition was accounted for as a business combination and, accordingly, the purchase consideration was allocated to the assets acquired and liabilities assumed based on their respective fair values. MPS‘s results of operations are included in the Company’s consolidated statements of comprehensive income from the date of acquisition.
	The aggregate purchase consideration was cash of $1.0 million. The amount allocated to intangible assets was determined based on management’s estimate of fair value using a probability weighted discounted cash flow model.
	The purchase price of $1.0 million exceeded the fair value of the net assets acquired of $0.6 million, resulting in goodwill of $0.4 million, none of which is deductible for income tax purposes. Goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from integrating the service offering and operations of MPS with those of the Company.
	The allocation of the fair value of assets acquired and liabilities assumed was as follows:
		(in thousands)
	Current assets	$	6
	Property and equipment	10
	Developed technology	210
	Customer relationships and contracts	339
	Accounts payable and accrued liabilities	(9		)
	Goodwill	444
	Total purchase consideration	$	1,000
	Developed technology, customer relationships and contracts are being amortized over a period of five years, five years and one year, respectively.
	MortgageCEO
	In January 2014, the Company acquired substantially all the assets of ARG Interactive, LLC (dba MortgageCEO), a SaaS company specializing in customer relationship management and marketing solutions for the residential mortgage industry. The purchase price was $5.0 million. The Company retained $0.5 million from the purchase price to cover closing capital settlement adjustments and any indemnity claims, which will be paid 18 months after the date of acquisition.

	Excess tax benefits associated with stock option exercises and other equity awards were credited to stockholders’ equity. The income tax benefits resulting from stock awards that were credited to stockholders’ equity were $6.7 million and 2.0 million for the years ended December 31, 2013 and 2012. There was no income tax benefits resulting from stock awards in 2011.
	The components of net deferred tax assets (liabilities) were as follows:

	Total deferred tax liabilities	(4,620		)		(4,567		)
	Net deferred tax assets	$	3,502			$	515
	At December 31, 2013, the Company had recorded $25,000 of net current deferred tax assets in “Prepaid expenses and other current assets” and $3.5 million of net long-term deferred tax assets in “Deposits and other assets” on the consolidated balance sheet. At December 31, 2012, the Company had recorded $0.6 million in net current deferred tax assets and $0.1 million in net long-term deferred tax liabilities.
	The Company continues to maintain a valuation allowance against the deferred tax assets related to certain state research and development tax credits, the realization of which is uncertain as the Company expects to generate additional such credits at a faster rate than it is able to utilize them. The valuation allowance decreased by $2.0 million in 2011, decreased by $6.5 million in 2012 and increased by $0.5 million in 2013.
	The Company utilized all of its federal net operating loss (“NOL”) during the year ended December 31, 2013. As of December 31, 2013, the Company had state NOL carryforwards of $11.2 million, available to reduce future taxable income. These state NOL carryforwards will begin to expire commencing in 2015. As of December 31, 2013, the Company also had federal and state research and development tax credit carryforwards of $3.1 million and $4.4 million, respectively. If it were to be utilized, the related federal tax benefit of $3.1 million would be credited to additional paid-in capital. The federal tax credit carryforwards begin to expire commencing in 2028. The state tax credit carryforwards may be carried forward indefinitely.
	Internal Revenue Code Section 382 places a limitation (the “Section 382 Limitation”) on the amount of taxable income that can be offset by NOL carryforwards after a change in control (generally greater than 50% change in ownership) of a loss corporation. California has similar rules. The Company’s capitalization as described herein may have created such a change. Generally, after a control change, a loss corporation cannot deduct NOL carryforwards in excess of the Section 382 Limitation. Due to these “change in ownership” provisions, utilization of the NOL carryforwards may be subject to an annual limitation regarding their utilization against taxable income in future periods. The Company has prepared a Section 382 Limitation analysis and does not believe that any of its NOL carryforwards are subject to expiration prior to utilization. Limitations have been imposed on the Company’s acquired subsidiaries.
	At December 31, 2013, the Company had $1.8 million of cumulative unrecognized tax benefits. If the benefits were to be recognized, $0.9 million would affect the effective tax rate and $0.9 million would reverse the valuation allowance against the deferred tax assets. The Company does not expect a significant change to its unrecognized tax benefits over the next twelve months. The unrecognized tax benefits may increase or change during the year for items that arise in the ordinary course of business.
	A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows:
		Year ended December 31,
		2013				2012				2011
		(in thousands)
	Beginning balance	$	1,262			$	1,855			$	1,328
	Additions based on tax positions related to the current year	402				130				301
	(Deductions) additions based on tax positions related to prior years including acquisitions	142				(723		)		226
	Ending balance	$	1,806			$	1,262			$	1,855
	The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. The Company’s tax years for 2001 and forward are subject to examination by the U.S. tax authorities and for 2010 and forward are subject to examination by the California tax authorities due to the carryforward of unutilized net operating losses and research and development credits.
	The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years, and that it does not have any tax positions that it is reasonably possible would materially increase or decrease the gross unrecognized tax benefits within the next twelve months.
	The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes. The Company did not incur any interest expense or penalties associated with unrecognized tax benefits during the years ended December 31, 2013, 2012 and 2011.
	Enactment of the American Tax Relief Act
	On January 2, 2013, the President signed into law The American Taxpayer Relief Act of 2012.  Under prior law, a taxpayer was entitled to a research tax credit for qualifying amounts paid or incurred on or before December 31, 2011. The 2012 Taxpayer Relief Act extended the research credit for two years to December 31, 2013.  The extension of the research credit was retroactive and included amounts paid or incurred after December 31, 2011.  As a result of the retroactive extension, the Company recognized a benefit of approximately $0.6 million  during the year ended December 31, 2013 for qualifying amounts incurred during calendar year 2012.
	IRS release of final tangible property regulations under IRC Sections 162(a) and 263(a)
	In September 2013, the IRS released final tangible property regulations (“repair regulations”) under Sections 162(a) and 263(a) of the Internal Revenue Code, regarding the deduction and capitalization of amounts paid to acquire, produce, or improve tangible property. The final repair regulations replace temporary repair regulations that were issued in December 2011 and are effective for tax years beginning January 1, 2014, with early adoption permitted for tax years beginning January 1, 2012. The Company is currently evaluating the impact of the final repair regulations on its consolidated financial statements but does not expect this to have a material impact to the financial statements.

	Legal Proceedings
	On March 25, 2011, Industry Access Incorporated (“Industry Access”) filed a patent infringement lawsuit against us and another defendant in the U.S. District Court for the Central District of California. The complaint alleges, among other things, that certain aspects of our Encompass loan management software system and related operations infringe a single patent, and seeks declaratory relief and unspecified damages from the defendants, including enhanced damages for willful infringement and reasonable attorneys’ fees. On June 24, 2011, the Court issued an order requiring plaintiff to serve the complaint on all defendants within three days of the order. On June 28, 2011, plaintiff served us with the complaint and we filed its answer on August 5, 2011 denying all material allegations of the complaint. On November 18, 2011 the other defendant filed with the United States Patent and Trademark Office (the “PTO”) a request for ex parte reexamination of Industry Access’ US Patent No 7,769,681, which the PTO granted on February 14, 2012. On December 15, 2011, we filed a motion to stay the litigation pending the reexamination, which the Court granted on February 28, 2012. On October 9, 2012, the PTO issued the reexamination certificate. The Court granted a motion to dismiss the other defendant from this action on April 7, 2013 and lifted the stay on April 11, 2013. The parties are in the claims construction phase of the litigation with a claim construction hearing that was scheduled for December 2, 2013. Discovery is ongoing and the trial has been rescheduled for December 2014 as further discussed below.
	On March 19, 2013, Industry Access filed a second patent infringement lawsuit against us in the U.S. District Court for the Central District of California. The complaint alleges, among other things, that our Encompass loan management software system, including the Encompass software, the Ellie Mae Network, Encompass Originator, Encompass Compliance Service, Encompass CenterWise, Encompass Electronic Document Management, Encompass Docs Solution and Encompass Product and Pricing Service, infringes U.S. Patent Nos. 8,117,120 and 8,145,563, which are continuations of U.S. Patent No. 7,769,681, asserted in the lawsuit described above. Plaintiff is seeking unspecified damages. On June 12, 2013, we filed a motion to dismiss or, in the alternative, to transfer this case to the Northern District of California, which the Court denied on September 18, 2013. Trial is set for December 2014.
	On September 12, 2013, we filed a motion to relate and consolidate the two Industry Access lawsuits so that all of Industry Access’ related patent infringement claims would be heard before the same judge on the same schedule.  Industry Access responded to this motion on October 11, 2013.  The Court granted our motion to consolidate on October 31, 2013.   The Court has scheduled the claim construction hearing for June 2, 2014.  Trial is set for December 2014.
	We believe that we have substantial and meritorious defenses in the newly consolidated case and, if similar claims are pursued, we intend to defend these and similar claims vigorously.
	We are also subject to various other legal proceedings and claims arising in the ordinary course of business. With respect to these matters and the litigations described above, we cannot predict the ultimate outcome of these legal proceedings and the amounts and ranges of potential damages associated with such proceedings cannot be estimated or assessed. An unfavorable outcome of these or the litigation could materially adversely affect our business, financial condition and results of operations.

As of December 31, 2013, 984,924 shares of the Company’s common stock previously available for issuance under the 2009 Plan were available for issuance under the 2011 Plan. The number of common shares reserved for issuance under the 2011 Plan increase automatically in January of each year by the least of (a) 1,666,666 shares, (b) five percent (5%) of the shares of common stock outstanding on the last day of the immediately preceding fiscal year and (c) such smaller number of shares of common stock as determined by the Company’s board of directors; provided, however that no more than 23,333,333 shares of common stock may be issued upon the exercise of incentive stock options.
	In December 2001, the Company replaced employee options for 758,049 shares with an exercise price of $13.83 per share with options having an exercise price of $3.75 per share. The Company recognized stock-based compensation benefit of $0.4 million for the year ended December 31, 2011. There was no stock-based compensation expense (benefit) recognized for the years ended December 31, 2013 and 2012.
	In April 2009, the Company replaced employee options for 1,993,923 shares with exercise prices of $5.40 and $5.94 with options having an exercise price of $1.38 and which included new vesting periods in accordance with the terms of the repricing plan (“April 2009 repricing”). The replacement options resulted in incremental stock-based compensation expense of $0.7 million, which was recognized ratably as the awards vested between March 2009 and October 2012.
	In August 2007, the Company granted an option to purchase 450,000 shares of the Company’s common stock at an exercise price of $5.94 per share to an executive officer of the Company. The option was canceled and repriced at $1.38 as part of the April 2009 repricing. Such option contains a performance requirement with vesting triggered by a liquidity event of the Company and the number of vested shares is determined based upon a return multiple as defined in the agreement. Upon the IPO in April 2011, as a liquidity event defined in the agreement occurred, the Company began recognizing compensation expense. The options were fully vested as of December 31, 2012. The related compensation expense recognized for the years ended December 31, 2012 and 2011 was $0.2 million and $0.3 million, respectively.
	In December 2010, the Company accepted promissory notes receivable from non-officer employees in consideration for the exercise of 36,400 fully vested nonqualified stock options. The promissory notes are secured by the underlying shares of common stock and bear interest at 0.32% per annum. The notes receivable are considered to be non-recourse notes under relevant accounting guidance. Since the notes are non-recourse for accounting purposes, the resulting exercises of the stock options have been determined to not be substantive and therefore not reflected in the Company’s balance sheet as of December 31, 2012 or 2013.
	In February 2011, the Company accepted promissory notes receivable from non-officer employees in consideration for the exercise of 29,163 fully vested incentive stock options that were subject to variable accounting.
	In November 2011, the Company’s board of directors approved extending the maturity date of each of the above outstanding secured promissory notes held by the Company. As a result of the extension approved by the Company’s board of directors, the promissory notes were due on the earlier of: (i) (x) November 11, 2013 for the promissory notes related to the 36,400 nonqualified options and (y) May 11, 2012 for the promissory notes related to the 29,163 incentive stock options; (ii) immediately prior to the dissolution or liquidation of the Company or upon a transaction resulting in a change of control, including by merger or by sale of all or substantially all of the Company’s assets; (iii) the employee’s termination as an employee or consultant of the Company; or (iv) the occurrence of an event of default as defined in the promissory note. As such, the Company collected all of the promissory notes prior to December 31, 2013. The modification resulting from this extension did not have a material impact on the financial statements.

	Intrinsic value of an option is the difference between the fair value of the Company’s common stock at the time of exercise and the exercise price to be paid. The aggregate intrinsic value for options outstanding at December 31, 2013 in the table above represents the total intrinsic value, based on the Company’s closing stock price of $26.87 as of December 31, 2013. Options outstanding that are expected to vest are net of estimated future option forfeitures. For the majority of stock options outstanding, the options vest over a four-year period and have a maximum contractual term of ten years.
	Following is additional information pertaining to the Company’s stock option activity:

	Proceeds received from options exercised	$	4,605		$	8,713			$	1,127
	As of December 31, 2013, total unrecognized compensation cost related to unvested stock options, adjusted for estimated forfeitures, was $11.4 million and is expected to be recognized over a weighted average period of 2.44 years.
	Restricted Stock Units and Performance Awards
	The fair value of the Company’s RSUs and Performance Awards is measured based upon the closing price of its underlying common stock as of the grant date and is recognized over the vesting term. Upon vesting, RSUs convert into an equivalent number of shares of common stock.
	In August 2012, the Company granted 147,000 Performance Awards (“2012 Performance Awards”) to designated participants under the 2011 Plan. The 2012 Performance Awards represented the right to receive between zero and 4 shares of the Company’s common stock upon achievement of certain performance goals during the performance period of July 1, 2012 through June 30, 2013. After the Company filed with the SEC its Quarterly Report on Form 10-Q for the quarter ended June 30, 2013, the Compensation Committee determined the level of achievement of the performance goals (the “Determination Date”), at which time the designated participants earned 588,000 shares of common stock. Of the issued shares, 25% were vested upon issuance and the remaining shares will vest 25% on each of the first three anniversaries of the Determination Date, subject to the continuous employment of the participant through such dates.
	In February 2013, the Company granted 113,000 Performance Awards (“2013 Performance Awards”) to designated participants under the 2011 Plan. The 2013 Performance Awards represent the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of January 1, 2013 through December 31, 2013. After the Company files with the SEC its Annual Report on Form 10-K for the year ended December 31, 2013, the Compensation Committee will determine the level of achievement of the performance goals (the “2013 Award Determination Date”), at which time the designated participants may earn between zero and 2.5 shares of common stock for each 2013 Performance Award. Shares of common stock earned, if any, will be issued after the 2013 Award Determination Date with 25% of the shares to vest upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the 2013 Award Determination Date, subject to the continuous employment of the participant through such dates. As of December 31, 2013, we expect that each award will convert to 1.1 shares of common stock on the 2013 Award Determination Date. As of December 31, 2013, the Compensation Committee has not determined the level of achievement of the performance goals. No forfeitures are expected.
	The following table summarizes the Company’s RSU and Performance Award activity:

Ending vested and expected to vest at December 31, 2013	236,637						565,300
RSUs and Performance Awards that are expected to vest are net of estimated future forfeitures. RSUs released during the year ended December 31, 2013 and 2012 had an aggregate intrinsic value of $0.5 million and $0.2 million, respectively, and an aggregate grant-date fair value of $0.3 million and $83,000, respectively. Performance Awards released during the year ended December 31, 2013 had an aggregate intrinsic value of $4.5 million and an aggregate grant-date fair value of $3.8 million. The number of RSUs released includes shares that we withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements.
As of December 31, 2013, total unrecognized compensation expense related to unvested RSUs and Performance Awards was $12.8 million and is expected to be recognized over a weighted average period of 2.4 years.
In February 2014, the Company granted 62,500 Performance Awards (“2014 Performance Awards”) to designated participants under the 2011 Plan. The 2014 Performance Awards represent the right to receive shares of the Company’s common stock upon achievement of certain performance goals during the performance period of January 1, 2014 through December 31, 2014. After the Company files with the SEC its Annual Report on Form 10-K for the year ending December 31, 2014, the Compensation Committee will determine the level of achievement of the performance goals (the “2014 Award Determination Date”), at which time the designated participants may earn between zero and 2.5 shares of common stock for each 2014 Performance Award. Shares of common stock earned, if any, will be issued after the 2014 Award Determination Date with 25% of the shares to vest upon issuance and the remaining shares to vest 25% on each of the first three anniversaries of the 2014 Award Determination Date, subject to the continuous employment of the participant through such dates.
Stock Options Issued to Non-employees
During the year ended December 31, 2013 and 2012, the Company granted options to purchase approximately 6,000 and 28,000 shares of common stock to individual consultants at an exercise price of $28.00 and $15.57 per share, respectively. The options were granted in exchange for consulting services. The grants vest over a period of two years. These options were granted under the 2011 Plan and are included in the option table above. The options issued to consultants are remeasured to fair value at the end of each accounting period. The Company recorded expense related to the issuance of options to consultants of $0.2 million in each of the years ended December 31, 2013 and 2012.
Employee Stock Purchase Plan
On March 7, 2011, the Company adopted an ESPP, which became effective on the date of adoption. The Company’s stockholders approved the ESPP on March 24, 2011. Employee participation in the ESPP began in the second quarter of 2011. Qualified employees are permitted to purchase the Company’s common stock at 85% of the fair market value of the common stock as of the commencement date of the offering period or as of the specified purchase date, whichever is lower. The ESPP is deemed compensatory and stock-based compensation is recognized in accordance with ASC 718, Stock Compensation.
The ESPP is designed to allow eligible employees and the eligible employees of the Company’s participating subsidiaries to purchase shares of common stock, at semi-annual intervals, with their accumulated payroll deductions.
The maximum aggregate number of shares which may be issued over the term of the ESPP is the sum of (a) 666,666 shares of common stock and (b) an annual increase on the first day of each year beginning in 2012 and ending in 2021, equal to the least of (i) 1,666,666 shares of common stock, (ii) one percent (1%) of the shares of common stock outstanding (on an as converted basis) on the last day of the immediately preceding fiscal year and (iii) such smaller number of shares of common stock as determined by the board of directors, which may be either authorized but unissued common stock or reacquired common stock, including shares of common stock purchased on the open market. In addition, no participant shall be permitted to participate in the ESPP if: (i) immediately after his or her election to participate, the participant would control 5% or more of the total combined voting power or value of all classes of the stock of the Company or any of its affiliates, or (ii) under the terms of the ESPP, the rights of the participant to purchase the Company’s common stock under the ESPP and all of its other qualified employee stock purchase plans or those of the Company’s affiliates would accrue at a rate exceeding $25,000 of fair market value of the common stock for each calendar year for which such right is outstanding at any time.
The weighted-average grant-date fair value of awards issued pursuant to the ESPP during the years ended December 31, 2013 and 2012 were $5.24 and $1.98 per share, respectively.
For the years ended December 31, 2013 and 2012, employees purchased 109,270 and 126,242 shares under the ESPP for a total of $1.9 million and $0.7 million, respectively. As of December 31, 2013, unrecognized compensation cost related to the current ESPP period which ends on February 28, 2014 is approximately $0.1 million and is expected to be recognized over the next 2 months.
Stock-Based Compensation Expense
Total stock-based compensation expense recognized by the Company consisted of:
	Year ended December 31,

The Company capitalized $0.1 million of stock compensation costs as software and website application development costs for the year ended December 31, 2013. The Company did not capitalize any stock-based compensation for the years ended December 31, 2012 and 2011 as such amounts were not material.
Valuation Information
The fair value of stock options and stock purchase rights granted under the 2009 Plan, the 2011 Plan and the ESPP were estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions:
	Year ended December 31,
	2013		2012			2011
Stock option plans:
Risk-free interest rate	0.95-1.87	%	0.74-1.10	%		1.17-2.20		%

Expected dividend yield	—	%	—	%		—		%
Volatility	36-37	%	37-47	%		52	%
(1) Employee Stock Purchase Plan established in 2011.
Stock compensation expense during the year ended December 31, 2013 and 2012 was recorded net of an estimated forfeiture rate of 4.4%. and 4.1%, respectively.
Due to the Company’s limited trading history as a publicly held company, the simplified method was used to estimate the expected term of options granted by taking the average of the vesting term and the contractual term of the option. To estimate volatility, management identified a group of publicly traded peer companies that operate in a similar industry and an estimate was determined based on the average historical volatilities of these peer companies. The risk-free interest rate used was the Federal Reserve Bank’s constant maturities interest rate commensurate with the expected life of the options. The expected dividend yield was zero, as the Company does not anticipate paying a dividend within the relevant time frame.

Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of Ellie Mae and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. 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 period. Management evaluates estimates on a regular basis including those relating to revenue recognition, the allowance for doubtful accounts, goodwill, other intangible assets, the valuation of deferred income taxes, stock-based compensation and unrecognized tax benefits, among others. Actual results could differ from those estimates and such differences may have a material impact on the Company’s consolidated financial statements and footnotes.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	All highly liquid investments with original maturities of 90 days or less are considered to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The fair values of the Company’s cash and cash equivalents, accounts receivable, notes receivable and accounts payable approximate their carrying values due to the short maturities of the instruments. The fair value of the Company’s capital lease obligations approximates the carrying value due to the short-term maturities of the leases.
	All of the Company’s investments that have maturities of greater than 90 days are classified as available-for-sale and are carried at fair value. The Company invests excess cash primarily in investment-grade interest-bearing securities such as money market accounts, certificates of deposit, commercial paper, corporate bonds, municipal and government agency obligations and guaranteed obligations of the U.S. government, all of which are subject to minimal credit and market risks. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. The cost of available-for-sale marketable securities sold is based on the specific identification method. Unrealized gains and losses, net of tax, are reported in stockholders’ equity as accumulated other comprehensive loss. Realized gains and losses are included in other income (expense), net. Interest and dividends are included in other income (expense), net when they are earned.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	The Company analyzes individual trade accounts receivable by considering historical bad debts, customer creditworthiness, current economic trends, changes in customer payment terms and collection trends when evaluating the adequacy of the allowance for doubtful accounts. Allowances for doubtful accounts are recognized in the period in which the associated receivable balance is not considered recoverable. Any change in the assumptions used in analyzing accounts receivable may result in changes to the allowance for doubtful accounts and is recognized in the period in which the change occurs. The Company writes off a receivable when all rights, remedies and recourses against the account and its principals are exhausted and records a benefit when previously reserved accounts are collected.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	The financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. The Company’s cash and cash equivalents are deposited with major financial institutions in the United States. At times, such deposits may be in excess of insured limits. Management believes that the Company’s investments in cash equivalents and available-for-sale investments are financially sound and have minimal credit risk. The Company’s accounts receivable are derived from revenue earned from customers located in the United States. The Company had no customers that represented 10% or more of revenues for the years ended December 31, 2013, 2012 and 2011. No customer represented more than 10% of accounts receivable as of December 31, 2013 and 2012.
Software and Web Site Development Costs	'
	Software and Website Development Costs
	The Company capitalizes internal and external costs incurred to develop internal-use software and website applications. Capitalized internal costs include salaries, benefits and stock-based compensation charges for employees that are directly involved in developing the software or website application, and depreciation of assets used in the development process. Capitalized external costs include third-party consultants involved in the development process, as well as other direct costs incurred as part of the development process.
	Capitalization of costs begins when the preliminary project stage is completed, and management authorizes and commits to funding a project and it is probable that the project will be completed and the software or website application will be used to perform the function intended. Internal and external costs incurred as part of the preliminary project stage are expensed as incurred.
	Capitalization ceases at the point at which the project is substantially complete and ready for its intended use, after all substantial testing is completed. Internal and external training costs and maintenance costs during the post-implementation operation stage are expensed as incurred.
	Internal-use software is amortized on a straight-line basis over its estimated useful life, generally three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The capitalized costs are included in “Property and equipment, net” in the accompanying consolidated balance sheets. For the years ended December 31, 2013 and 2012, the Company capitalized software and website application development costs of $5.0 million and $0.5 million, respectively.
Property and Equipment	'
	during the year ended December 31, 2013 and no such amortization recorded during the years ended December 31, 2012 and 2011.
	Property and Equipment
	Property and equipment are stated at cost less accumulated depreciation and are depreciated on a straight-line basis over their estimated useful lives, which is generally three years. Leasehold improvements are amortized over the shorter of the asset’s useful life or term of the lease.
Business Combinations	'
	Business Combinations
	The Company recognizes and measures the identifiable assets acquired in a business combination, the liabilities assumed and any non-controlling interest in the acquiree, measured at their fair values as of the acquisition date. Under ASC 805, the Company recognizes contingent consideration arrangements at their acquisition-date fair values with subsequent changes in fair value reflected in earnings, recognizes pre-acquisition loss and gain contingencies at their acquisition-date fair values (with certain exceptions), capitalizes in-process research and development assets, expenses acquisition-related transaction costs as incurred, and limits the capitalization of acquisition-related restructuring as of the acquisition date. Due to the inherent uncertainty in the Company’s best estimates and assumptions, they are subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with the corresponding offset to goodwill. Any subsequent adjustments, including changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties after the measurement period, are recognized in earnings rather than as an adjustment to the cost of the acquisition.
Goodwill and Other Intangible Assets	'
	isition.
	Goodwill
	The Company records goodwill in a business combination when the consideration paid exceeds the fair value of the net assets acquired. Goodwill is not amortized, but is tested for impairment at least annually in the fourth quarter of the Company’s fiscal year, or whenever changes in circumstances indicate that the fair value of a reporting unit is less than its carrying amount, including goodwill. The annual test is performed at the reporting unit level using a fair-value based approach. The Company’s operations are organized as one reporting unit. In testing for a potential impairment of goodwill, the Company first compares the carrying value of assets and liabilities to the estimated fair value. If estimated fair value is less than carrying value, then potential impairment exists. The amount of any impairment is then calculated by determining the implied fair value of goodwill using a hypothetical purchase price allocation. Impairment is equivalent to any excess of goodwill carrying value over its implied fair value.
	The process of evaluating the potential impairment of goodwill requires significant judgment at many points during the analysis, including calculating fair value of each reporting unit based on estimated future cash flows and discount rates to be applied.
	The Company completed its annual impairment tests during the fourth quarters of 2013, 2012 and 2011 and determined that goodwill was not impaired.
	Other Intangible Assets
	Other intangible assets are stated at cost less accumulated amortization. Other intangible assets include developed technology, trade names and customer lists and contracts. Intangible assets with finite lives are amortized on a straight-line basis over the estimated periods of benefit, as follows:
	Developed technology	3-5 years
	Trade names	3 years
	Customer lists and contracts	1-9 years
	The Company evaluates its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to future undiscounted net cash flows expected to be generated by the asset group. If such assets are considered to be impaired, the impairment loss to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount and fair value less costs to sell.
Impairment of Long-Lived Assets	'

	Impairment of Long-Lived Assets
	The Company evaluates its long-lived assets for indications of possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Revenue Recognition	'
	r the years ended December 31, 2013, 2012 and 2011.
	Revenue Recognition
	The Company generates revenue primarily from on-demand and on-premise fees for software and related services. On-demand revenues are revenues generated from company-hosted software subscriptions that customers access through the Internet as well as revenues from a small number of customers that have opted to self-host a portion of the software but pay fees based on a per closed loan, or success, basis subject to monthly base fees, which the Company refers to as Success-Based Pricing. On-demand revenues are also comprised of software services sold transactionally and Ellie Mae Network transaction fees. On-premise revenues are revenues generated from maintenance services, sales of customer-hosted software licenses (except for customer-hosted Success-Based Pricing revenues, which are included in on-demand revenues described above), and professional services, which include consulting, implementation and training services. Sales taxes assessed by governmental authorities are excluded from revenue.
	The Company commences revenue recognition when all of the following conditions are satisfied:
	•There is persuasive evidence of an arrangement
	•The service has been or is being provided to the customer
	•The collection of the fees is reasonably assured; and
	•The amount of fees to be paid by the customer is fixed or determinable.
	On-Demand Revenues
	Subscription Services and Usage-Based Fee Arrangements. Subscription services and usage-based fee arrangements generally include a combination of the Company’s products delivered as software-as-a-service (“SaaS”) and support services. These arrangements are non-cancelable and do not contain refund-type provisions. These revenues generally include the following:
	SaaS Encompass Revenues. The Company offers web-based, on-demand access to Encompass for a monthly recurring fee. The Company provides the right to access its loan origination software and handles the responsibility of managing the servers, providing security, backing up the data and applying updates; however, except where customers self-host a portion of the software in a Success-Based Pricing structure, customers under SaaS arrangements may not take possession of the software at any time during the term of the agreement. Subscription revenues are recognized ratably over the contract terms beginning on the commencement date of each contract, which is the date the Company’s service is made available to customers. Contracts generally range from one year to five years.
	Alternatively, customers can elect to pay on a per closed loan, or success, basis. Success basis contracts generally have a term of one to five years and are subject to monthly base fees, which enable customers to close loans up to a contractually agreed-to minimum number of transactions, and additional closed loan fees, which are assessed for loans closed in excess of the minimum. Revenue is earned from both base fees and additional closed loan fees as the result of the customer’s usage of Encompass. Monthly base fees are recognized over the respective monthly service period as the software is utilized. Additional closed loans fees are recognized when the loans are reported as closed. This offering also includes Encompass CenterWise, Encompass Compliance Service and Encompass Docs Solution for Encompass as integrated components, which are combined elements of the arrangement that is delivered in conjunction with the SaaS Encompass offering and therefore is not accounted for separately.
	Encompass CenterWise Revenues. Encompass CenterWise is a bundled offering of electronic document management (“EDM”) and websites used for customer relationship management. Generally, revenue is recognized for Encompass CenterWise after the service is rendered, except when Encompass CenterWise is automatically included as an integrated component of the SaaS Encompass offering, in which case the associated revenue is recognized as described above.
	Services Revenues. The Company provides mortgage-related and other business services, including automated documentation preparation and compliance reports. Services revenues are recognized after the services are rendered.
	Transaction Revenues. The Company has entered into agreements with various lenders, service providers and certain government agencies participating in the mortgage origination process that provide them access to, and ability to interoperate with, mortgage originators on the Ellie Mae Network. Under these agreements, the Company earns transaction fees when transactions are processed through the Ellie Mae Network. Transaction revenues are recognized when there is evidence that the qualifying transactions have occurred on the Ellie Mae Network and collection of the resulting receivable is reasonably assured.
	On-Premise Revenues
	With the exception of revenue from customers that self-host a portion of the software in a Success-Based Pricing structure (which is recognized as described above), revenue from the sale of software licenses is recognized in the month in which the required revenue recognition criteria are met, generally in the month in which the software is delivered. Revenue from the sale of maintenance services and professional services is recognized over the period in which the services are provided.
	Multiple Element Arrangements
	The Company has entered into both subscription services and software arrangements with multiple elements. When subscription services involve multiple elements that qualify as separate units of accounting, the Company allocates arrangement consideration at the inception of an arrangement to all deliverables based on the relative selling price method in accordance with the selling price hierarchy, which includes: (i) vendor specific objective evidence (“VSOE”) if it is available; (ii) third-party evidence (“TPE”) if VSOE is not available; and (iii) the best estimate of selling price (“BESP”) if neither VSOE nor TPE is available.
	VSOE. The Company determines VSOE based on its historical pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range. The Company has not historically priced its subscription services within a narrow range. As a result, the Company has not been able to establish selling prices for subscription services based on VSOE.
	TPE. When VSOE cannot be established for deliverables in multiple element arrangements, the Company applies judgment with respect to whether it can establish a selling price based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of differentiation such that the comparable pricing of services with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor services’ selling prices are on a standalone basis. As a result, the Company has not been able to establish selling prices based on TPE.
	BESP. When the Company is unable to establish a selling price using VSOE or TPE, the Company uses BESP in its allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the service was sold on a standalone basis. When establishing BESP, the Company reviews company specific factors used to determine list price and makes adjustments as appropriate to reflect current market conditions and pricing behavior. The Company’s process for establishing list price includes assessing the cost to provide a particular product or service, surveying customers to determine market expectations, analyzing customer demographics and taking into account similar products and services historically sold by the Company. The Company continues to review the factors used to establish list price and adjusts BESP as necessary.
	Because the Company has determined that neither VSOE nor TPE is available, it uses BESP to allocate the selling price to multiple elements in subscription services arrangements. The amount of revenue allocated to delivered items is limited by contingent revenue, if any.
	In order to treat deliverables in a multiple-deliverable arrangement as separate units of accounting, the deliverables must have standalone value upon delivery. Subscription services have standalone value as such services are often sold separately. Additionally, the Company has concluded that professional services have standalone value. In establishing standalone value, the Company considered the following factors for each professional services agreement: availability of the services from other vendors, the nature of the professional services, and the timing of when the professional services contract was signed in comparison to the subscription service start date.
	For software arrangements with multiple elements (e.g., undelivered maintenance and support contracts bundled with licenses), revenue is allocated to the delivered elements of the arrangement when VSOE is determinable, using the residual value method based on objective evidence of the fair value of the undelivered elements, which is specific to the Company. When VSOE is not determinable, the entire arrangement is recognized ratably over the term of the contract. Revenue is recognized under this model upon receipt of cash payment from the customer if collectability is not reasonably assured and when other revenue recognition criteria have been met. The VSOE of fair value for maintenance and support obligations related to licenses is based upon the prices paid for the separate renewal of these services by the customer. Maintenance revenues are recognized ratably over the period of the maintenance contract.

Maintenance revenues are recognized ratably over the period of the maintenance contract.
	Deferred Revenue
	Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. Balances consist primarily of maintenance and professional services not yet provided as of the balance sheet date. Deferred revenue that will be recognized during the succeeding 12 month period is recorded as current deferred revenue, and the remaining portion is recorded as other long-term liabilities.
	Deferred
Deferred Commission Expense	'
	ilities.
	Deferred Commission Expense
	Deferred commission expenses are the incremental costs that are directly associated with non-cancelable subscription contracts with customers and consist of sales commissions paid to our direct sales force. Commissions are calculated based on a percentage of the revenues for the non-cancelable term of subscription contracts, which are typically one to five years.
	Prior to 2013, commissions were paid and recognized as sales expense when customer payments for contracted services were received on a monthly basis because commissions were earned based on receipt of customer payments. In 2013, we amended our commission plans to provide for payment after the customer's contract is signed. As a result of the change in commission plans, beginning in 2013, commission expense is deferred and amortized to sales expense over the non-cancelable terms of the related subscription contracts. The deferred commission expense amounts are recoverable through the future revenue streams under the non-cancelable customer contracts. The new plans also include claw back provisions, which require repayment of a proportionate amount of commissions, should customers cancel their contracts prior to the end of the initial contractual term.
Warranties and Indemnification	'
	, 2012.
	Warranties and Indemnification
	The Company provides a warranty for its software products and services to its customers and accounts for its warranties as a contingent liability. The Company’s software is generally warranted to perform substantially as described in the associated product documentation. The Company’s services are generally warranted to be performed consistent with industry standards. If there is a failure of such warranties, the Company generally is obligated to repair or replace the product or service or correct it to conform to the warranty provision. If the Company is unable to do so, the customer is entitled to terminate the agreement with the Company. With respect to Encompass Compliance Service, the Company provides a limited warranty, which limits its liability to the reimbursement for losses incurred by a customer due to fines, penalties or judgments imposed or levied upon a customer as a result of a violation of a specific law, rule or regulation resulting from an error in the provision of the Company’s Encompass Compliance Service. The Company’s maximum exposure is limited under its services agreements to the greater of the total service fees paid by a customer for such services during the specified period preceding the relevant claim, typically six to 12 months, or a specified dollar amount ranging from $50,000 to $5.0 million. The Company has not historically incurred any significant claims and maintains a total of $10.0 million in professional liability insurance coverage. The Company has not provided for a warranty accrual as of December 31, 2013 or 2012. To date, the Company’s product warranty expense has not been significant.
	The Company generally agrees to indemnify its customers against legal claims that the Company’s software products infringe certain third-party intellectual property rights and accounts for its indemnification obligations as a contingent liability. In the event of such a claim, the Company is obligated to defend its customer against the claim and to either settle the claim at the Company’s expense or pay damages that the customer is legally required to pay to the third-party claimant. In addition, in the event of an infringement, the Company agrees to modify or replace the infringing product, or, if those options are not reasonably possible, to refund the cost of the software, as pro-rated over a period of years. To date, the Company has not been required to make any payment resulting from infringement claims asserted against its customers. The Company has not recorded a liability for infringement costs as of December 31, 2013 or 2012.
	The Company has obligations under certain circumstances to indemnify each member of the Company’s board of directors against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws and certificate of incorporation.
Cost of Revenues	'
	Cost of Revenues
	The Company’s cost of revenues consists primarily of salaries, benefits and related costs (including stock-based compensation), allocated facilities costs, customer support, data centers, expenses for document preparation, income verification and compliance services, depreciation on computer equipment used in supporting the Ellie Mae Network, the Company’s SaaS Encompass and Encompass CenterWise offerings, amortization of acquired intangible assets directly involved in revenue producing activities and professional services associated with implementation of software.

Stock-Based Compensation	'
	were $0.4 million, $0.3 million, and $0.3 million, respectively.
	Stock-Based Compensation
	The Company recognizes stock-based compensation related to awards granted under its 2009 Stock Option and Incentive Plan (the “2009 Plan”), 2011 Equity Incentive Award Plan (the “2011 Plan”) and Employee Stock Purchase Plan (“ESPP”).
	The Company recognizes compensation expense related to stock option grants that are ultimately expected to vest based on estimated fair values on the date of grant using the Black-Scholes option-pricing model. Such expense is recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period.
	The Company recognizes compensation expense related to restricted awards, restricted stock unit awards (“RSUs”), and performance share awards (“Performance Awards”) based on the fair market value of the underlying shares of common stock as of the date of grant. Expense related to the restricted awards and the RSUs are recognized on a straight-line basis over the requisite service period of the award, which generally equals the vesting period. Expense related to the Performance Awards is recognized under an accelerated method over the requisite service period of the award, which recognizes a larger portion of the expense during the beginning of the vesting period than in the end of the vesting period. Management estimates the probable number of shares of common stock that will be granted until the achievement of the performance goals is known.
	The date of grant is the date at which the Company and the employee reach a mutual understanding of the key terms and conditions of the award, appropriate approvals are received by approval by the board of directors and the Company becomes contingently obligated to issue equity instruments to the employee who renders the requisite service.
	The Company is required to estimate potential forfeitures of stock grants and adjust recorded compensation cost accordingly. The estimate of forfeitures is based on historical experience and is adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from the prior estimates. Changes in estimated forfeitures will be recognized in the period of change and will impact the amount of stock-based compensation expense to be recognized in future periods.
	All stock option awards to non-employees are accounted for at the fair value of the consideration received or the fair value of the equity instrument issued, as calculated using the Black-Scholes option-pricing model. The measurement of stock-based compensation for non-employees is subject to periodic adjustments as the options vest, and the expense is recognized over the period services are rendered.
Income Taxes	'
	Income Taxes
	The Company accounts for income taxes under the asset and liability method, which requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. The Company’s determination of its valuation allowance is based upon a number of assumptions, judgments and estimates, including forecasted earnings, future taxable income and the relative proportions of revenue and income before taxes in the various jurisdictions in which it operates.
	The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. Tax positions are based upon their technical merits, relevant tax law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax positions. A tax position is only recognized in the financial statements if it is “more likely than not” to be sustained based solely on its technical merits as of the reporting date. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments that could result in recognition of additional tax benefits or additional charges to the tax provision and may not accurately reflect actual outcomes. The Company has a policy to classify accrued interest and penalties associated with uncertain tax positions together with the related liability, and the expenses incurred related to such accruals are included in the provision for income taxes.

	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Topic 740 - Income Taxes (“ASU 2013-11”) which provides guidance to improve the presentation of an unrecognized benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We intend to adopt this standard in the first fiscal quarter of 2014 and do not expect the adoption will have a material impact on our consolidated financial statements.
