Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. All significant intercompany transactions and balances have been eliminated.

Significant Estimates and Judgments

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of net revenues and expenses during the reporting periods. These estimates and assumptions could have a material effect on our future results of operations and financial position. Significant items subject to our estimates and assumptions include stock-based compensation, income taxes, valuation of acquired goodwill and intangible assets, allowance for doubtful accounts, revenue returns reserve, unrecognized tax benefits, acquisition-related contingent liabilities and the useful lives of property and equipment and intangible assets. As a result, actual amounts could differ from those presented herein.

Business Segment

We have one operating and reporting segment consisting of various products and services that are all related to our marketplace for digital offers. Our chief operating decision maker is our Chief Executive Officer. Our Chief Executive Officer allocates resources and assesses performance of the business and other activities at a single reporting segment level.

Cash and Cash Equivalents

All highly-liquid investments with an original maturity of three months or less at the date of purchase are considered to be cash equivalents.

Accounts Receivable, Net

Accounts receivable, net represent amounts due from retailers, through various performance marketing networks, for commissions earned on consumer purchases and amounts due for premium placement advertising. We record an allowance for doubtful accounts in an amount equal to the estimated probable losses net of recoveries, which are based on an analysis of historical bad debt, current receivables aging and expected future write-offs of uncollectible accounts, as well as an assessment of specific identifiable accounts considered at risk or uncollectible. Accounts receivable are written off against the allowance for doubtful accounts when it is determined that the receivable is uncollectible.

The following table summarizes our allowance for doubtful accounts (in thousands):

Property and Equipment, Net

Property and equipment, net includes assets such as furniture and fixtures, leasehold improvements, computer hardware, office and telephone equipment and certain capitalized internally developed software and website development costs. We record property and equipment at cost less accumulated depreciation and amortization, using the straight-line method. Ordinary maintenance and repairs are charged to expense, while expenditures that extend the physical or economic life of the assets are capitalized. Property and equipment are depreciated over their estimated economic lives, which range from three to five years, using the straight-line method. Leasehold improvements are amortized over the shorter of the estimated useful lives of the improvements or the lease term. Capitalized internally developed software and website development costs are depreciated over their estimated useful lives, which range from two to three years. We perform reviews for the impairment of property and equipment when management believes events or circumstances indicate the carrying amount of an asset may not be recoverable.

Goodwill and Other Intangible Assets

Goodwill arises from business combinations and is measured as the excess of the cost of the business acquired over the sum of the acquisition-date fair values of tangible and identifiable intangible assets acquired, less any liabilities assumed.

We evaluate goodwill for impairment annually on October 1, during the fourth quarter of each year, or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. Events or circumstances that could trigger an impairment test include, but are not limited to, a significant adverse change in the business climate or in legal factors, an adverse action or assessment by a regulator, a loss of key personnel, significant changes in our use of the acquired assets or the strategy for our overall business, significant negative industry or economic trends, significant underperformance relative to operating performance indicators and significant changes in competition. The Company determined that no triggering events occurred during the year ended December 31, 2014.

We evaluate the recoverability of goodwill using a two-step impairment process tested at our sole reporting segment level. In the first step, the fair value for our reporting unit is compared to our book value including goodwill. If the fair value is less than the book value, a second step is performed that compares the implied fair value of goodwill to the book value of the goodwill. The fair value for the implied goodwill is determined based on the difference between the fair value of the sole reporting segment and the net fair value of the identifiable assets and liabilities excluding goodwill. If the implied fair value of the goodwill is less than the book value, the difference is recognized as an impairment charge in the consolidated statements of operations. We did not record any goodwill impairment charges during the years ended December 31, 2014, 2013 and 2012.

Identifiable intangible assets consist of acquired customer intangible assets, marketing-related intangible assets, contract-based intangible assets, and technology-based intangible assets. Intangible assets with definite lives are amortized over their estimated useful lives on a straight-line or accelerated basis. See Note 4, “Goodwill and Other Intangible Assets”. The method of amortization applied represents our best estimate of the distribution of the economic value of the identifiable intangible assets. The factors we consider in determining the useful lives of identifiable intangible assets included the extent to which expected future cash flows would be affected by our intent and ability to retain use of these assets, including the period of time that would capture 90% or more of the assets value on a perpetuity basis.

Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of intangible assets may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. When such events occur, we compare the carrying amounts of the assets to their undiscounted cash flows. If this comparison indicates that there is impairment, the amount of the impairment is calculated as the difference between the carrying value and the fair value.

Deferred Financing Costs

We capitalize underwriting, legal and other direct costs incurred related to the issuance of debt, which are recorded as deferred charges and amortized to interest expense over the term of the related debt using the effective interest method. Upon the extinguishment of the related debt, any unamortized capitalized deferred financing costs are recorded to interest expense.

Lease Obligations

We categorize leases at their inception as either operating or capital leases, and may receive renewal or expansion options, rent holidays, leasehold improvement allowances and other incentives on certain lease agreements. We recognize operating lease costs on a straight-line basis over the term of the agreement, taking into account adjustments for market provisions, such as free or escalating base monthly rental payments, or deferred payment terms, such as rent holidays, that defer the commencement date of required payments. We record rent expense associated with operating lease obligations in general and administrative expenses in the consolidated statements of operations.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, services have been rendered, the fee to the paid retailer is fixed or determinable and collectability of the resulting receivable is reasonably assured. For commission revenues, which represent the substantial majority of our net revenues, revenue recognition generally occurs when a consumer, having visited one of our websites and clicked on a digital offer for a paid retailer, defined as a retailer with which we have a contract, makes a purchase with such paid retailer, and completion of the order is reported to us by such paid retailer, either directly or through a performance marketing network. The reporting by the paid retailer includes the amount of commissions the paid retailer has calculated as owing to us. Certain paid retailers do not provide reporting until a commission payment is made. In those cases, which have historically not been significant, we record commission revenues on a cash basis. For advertising revenues, revenue recognition occurs ratably over the period that we display a retailer’s advertisements on our websites and mobile applications. We estimate and record a reserve, based upon actual, historical return rates as reported to us by the paid retailers, to provide for end-user cancelations or product returns, which may not be reported by the paid retailer or performance marketing network until a subsequent date. As such, we report commission revenues net of the estimated returns reserve. Net revenues are reported net of sales taxes, where applicable. The following table summarizes our revenue returns reserve (in thousands):

Our payment arrangements with paid retailers are both direct and through performance marketing networks, which act as intermediaries between the paid retailers and us. No paid retailer individually accounted for more than 10% of net revenues or accounts receivable for any of the years ended December 31, 2014, 2013 and 2012.

Cost of Net Revenues

Cost of net revenues is composed of direct and indirect costs incurred to generate revenue. These costs consist of personnel costs of our salaried merchandising and technology support employees and fees paid to third-party contractors engaged in the operation and maintenance of our existing websites and mobile applications. Such technology costs also include website hosting and Internet service costs. Other costs include allocated facility and general information technology costs.

Sales and Marketing Expense

Our sales and marketing expense consists of personnel costs for our sales, marketing, search engine optimization, search engine marketing and business intelligence employees, as well as online, brand and other marketing expenses. Our online, brand and other marketing costs include search engine fees, advertising on social networks, television advertising, promotions, display advertisements, creative development fees, public relations, email campaigns, trade shows and other general marketing costs. Other costs include allocated facility and general information technology costs.

Advertising Expenses

We expense all advertising costs as incurred. Advertising expenses included in sales and marketing expense were $23.1 million, $22.2 million and $13.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Product Development

Our product development expense consists primarily of personnel costs of our product management and software engineering teams, as well as fees paid to third-party contractors and consultants engaged in the design, development, testing and improvement of the functionality and user experience of our websites and mobile applications.

General and Administrative Expense

Our general and administrative expense represents personnel costs for employees involved in general corporate functions, including finance, accounting, legal and human resources, among others. Additional costs included in general and administrative expense include professional fees for legal, audit and other consulting services, the provision for doubtful accounts receivable, travel and entertainment, charitable contributions, recruiting, allocated facility and general information technology costs and other general corporate overhead expenses.

Stock-Based Compensation Expense

Stock-based compensation expense is measured at the grant date based on the estimated fair value of the award, net of estimated forfeitures. We recognize these compensation costs on a straight-line basis over the requisite service period of the award. Forfeiture rates are estimated at grant date based on historical experience and adjusted in subsequent periods for differences in actual forfeitures from those estimates. We include stock-based compensation expense in cost of net revenues and operating expenses in our consolidated statements of operations, consistent with the respective employees’ cash compensation. We determine the fair value of stock options on the grant date using the Black-Scholes-Merton valuation model.

Fair Value of Financial Instruments

The carrying amounts of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and notes payable, approximate fair value due to the instruments’ short-term maturities or, in the case of the long-term notes payable, based on the variable interest rate feature. We record derivative liabilities at fair value.

Income Taxes

The provision for income taxes is determined using the asset and liability method. Deferred tax assets and liabilities are calculated based upon the temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases using the enacted tax rates that are applicable in a given year. The deferred tax assets are recorded net of a valuation allowance when, based on the available supporting evidence, we believe it is more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods.

The Company may be subject to income tax audits by the respective tax authorities in any or all of the jurisdictions in which the Company operates, including the United States, the United Kingdom, France, Germany, and the Netherlands. Significant judgment is required in determining uncertain tax positions. We utilize a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. We adjust these reserves in light of changing facts and circumstances, such as the closing of an audit or the refinement of an estimate. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We include interest and penalties related to uncertain tax positions in the provision for income taxes on our consolidated statements of operations. See Note 12, “Income Taxes.”

Foreign Currency

Our operations outside of the U.S. generally use the local currency as their functional currency. Assets and liabilities for these operations are translated at exchange rates in effect at the balance sheet date. Income and expense accounts are translated at average exchange rates for the period. Foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss). Gains and losses from foreign currency denominated transactions, which were a $0.9 million loss, net, in 2014, a $0.7 million gain, net, in 2013 and not significant in 2012, are recorded in other income (expense), net in our consolidated statements of operations.

Derivative Financial Instruments

Our operations outside of the U.S. expose us to various market risks that may affect our consolidated results of operations, cash flows and financial position. These market risks include, but are not limited to, fluctuations in currency exchange rates. Our primary foreign currency exposures are in Euros and British Pound Sterling. As a result, we face exposure to adverse movements in currency exchange rates as the financial results of our operations are translated from local currency into U.S. dollars upon consolidation.

We have entered into a derivative instrument to hedge certain exposures of nonfunctional currency denominated intercompany loans and may enter into further such instruments in the future. We have not elected to apply hedge accounting or hedge accounting does not apply. Gains and losses resulting from a change in fair value for these derivatives are reflected in the period in which the change occurs and are recorded in other income (expense), net in our consolidated statement of operations. During the year ended December 31, 2014, we recorded a gain of $0.2 million related to our foreign exchange derivative instruments. The fair value and notional principal amount of our outstanding foreign exchange derivative instrument as of December 31, 2014 are $0.0 and $9.0 million, respectively. We did not enter into any foreign exchange derivative instruments prior to the year ended December 31, 2014.

We do not use financial instruments for trading or speculative purposes. Derivative instruments are recorded on the balance sheet at fair value and are short-term in duration. We are exposed to the risk that counterparties to derivative contracts may fail to meet their contractual obligations.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued new guidance that supersedes existing revenue recognition requirements. The guidance provides a five-step process to recognize revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration expected in exchange for those goods and services. The guidance requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, using one of two retrospective application methods. Early application is not permitted. We are currently evaluating which of the two retrospective application methods we will use and the effect that the adoption of this guidance will have on our financial statements.

	Total	$	11,564		$	20,788		$	3,145


	Tangible assets, which include cash and cash equivalents and accounts receivable, were valued at their respective carrying amounts, which we believe approximate their fair values at the respective acquisition dates. The liabilities assumed in connection with these acquisitions, which were recorded at their fair value at the acquisition dates, include accrued liabilities, accounts payable and deferred tax liabilities. For all acquisitions, goodwill represents the excess of the purchase price over the aggregate fair value of the net identifiable assets acquired. In connection with our acquisition efforts we incurred approximately $0.1 million, $1.4 million and $0.6 million in direct acquisition costs in the years ended December 31, 2014, 2013 and 2012, respectively, all of which were expensed as incurred and are included in general and administrative expenses on the consolidated statements of operations.
	Goodwill resulted primarily from acquiring a business in a market characterized by high profitability, numerous participants, with none having a dominant market position and specialized processes and procedures, none of which qualify as a separate intangible asset.
	The valuation of identifiable intangible assets acquired reflects our estimates based on, among other factors, use of established valuation methods. The value of customer relationships was determined using the income approach. The value of marketing-related intangible assets was determined using the relief from royalty method. Contract-based intangible assets have been valued based on an income-based approach, specifically the with/without method. The value of acquired technology was determined based on a cost-to-recreate methodology. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line or accelerated method and the estimated useful lives of one to 15 years. The method of amortization applied represents our best estimate of the distribution of the economic value of the identifiable intangible assets.
	The acquired marketing-related intangible assets consist primarily of trade names, domain names and well-developed traffic acquisition strategies. These trade and domain names play a pivotal role in generating visits and consumer leads for retailers. In addition, the traffic acquisition methodologies such as search engine optimization processes and techniques, email subscriber lists and campaign processes and other direct marketing capabilities also contribute significantly to generating consumer leads and visits. Our intent is to use the brand and domain names for the foreseeable future and to build upon the established traffic-acquisition methodologies. Accordingly, we utilized a 15 year useful life to both value and amortize these assets.
	The acquired customer-related intangible assets consist solely of contracts with retailers. The businesses we acquired typically had relationships with a substantial portion of the major online retailers that offered digital coupons through affiliate marketing relationships. The customer relationships were valued predominantly using an income approach (multi-period excess earnings method.) Based on the attrition factors applied, the expected useful life of customer relationships from this income approach is 15 years. Although the contracts we enter into with retailers are cancelable upon short or no notice and without penalty, we determined the useful life of these relationships to be longer-term in nature based upon consideration of several factors. These factors included the fact that couponing has been used in-store by retailers for an extended period; the growth in revenues of the acquired businesses which indicated growing use of coupons by retailers and consumers; the higher level of retailer relationship management that we provide as compared to the periods prior to acquisition; and historically low attrition rates. Based on these factors, we determined that the useful life of these relationships would extend to the foreseeable future and, accordingly, utilized a period of 15 years both to value and amortize these assets.
	YSL Ventures, Inc.
	On October 9, 2013, we acquired 100% of the outstanding capital stock of YSL Ventures, Inc., a private company that operated under the name Zendeals, for $11.6 million of cash consideration.
	In conjunction with the acquisition of YSL Ventures, Inc., we entered into deferred compensation arrangements with the former owners of YSL Ventures, Inc., at which time we transferred $6.2 million into an escrow account, to be paid to the owners over a two year period, with $3.1 million paid in October 2014, and the remainder to be paid in equal quarterly installments over the following year, contingent upon the former employees’ continued employment with RetailMeNot.

	The goodwill resulting from the acquisition of YSL Ventures, Inc. is not deductible for tax purposes.
	Ma-Reduc.com
	On July 1, 2013, our wholly owned subsidiary, RetailMeNot, France, acquired 100% of the outstanding capital stock of ABCYNE, a private company and the operator of Ma-Reduc.com, a digital coupon website in France. The total purchase price of $20.8 million was comprised of: (i) $15.0 million initial cash consideration, (ii) notes payable issued by RetailMeNot, France, with an aggregate principal amount of $4.9 million to the shareholders, bearing interest at a rate of 3.0% per annum and due, and paid in full, in 2014 and (iii) additional cash consideration for working capital of $0.9 million.
	The goodwill resulting from the acquisition of Ma-Reduc.com is not deductible for tax purposes.
	Actiepagina.nl
	On March 1, 2013, we acquired certain assets and liabilities of Actiepagina B.V. associated with Actiepagina.nl, its website based in the Netherlands. The total purchase price of $3.1 million was comprised of: (i) $2.0 million cash consideration and (ii) a $1.1 million note payable issued to the seller, due, and paid in full, in 2014.
	The resulting goodwill from the acquisition of Actiepagina.nl is not deductible for tax purposes.

	Senior Debt

	On December 23, 2014, we entered into a second amended and restated revolving credit and term loan agreement with certain lenders, or Senior Debt. The Senior Debt consists of a $125.0 million revolving credit facility, an additional uncommitted revolving credit facility of up to $65.0 million and a $50.0 million term loan facility. The term loan facility was fully borrowed on December 23, 2014, and was used, in part, to fully repay the $26.3 million of borrowings outstanding under our prior senior debt facility, which obligations were repaid in full effective upon the closing of the Senior Debt. On December 31, 2014, we had the full $125.0 million available for borrowings under the revolving credit facility.

	We pay a quarterly revolving credit facility fee of 50 basis points per annum. At our option, borrowings under both the term loan facility and the revolving credit facility bear interest at either the base rate or a eurodollar-based rate (each as more fully described in the second amended and restated revolving credit and term loan agreement) plus an applicable margin as determined based on the senior secured debt to EBITDA ratio (as more fully described in the second amended and restated revolving credit and term loan agreement). These rates are summarized in the following table:



	Basis for Pricing		Level I		Level II	Level III		Level IV
	Consolidated Senior Secured Debt/EBITDA		<1.00:1.00		>1.00:1.00	>1.50:1.00		>2.00:1.00

					<1.50:1.00	<2.00:1.00

	Term Loan Base Rate Margin		75 basis points		125 basis points	175 basis points		225 basis points



	Interest is payable quarterly in arrears for base rate borrowings and on the last day of the applicable eurodollar-interest period for any eurodollar-based borrowings. Principal payments on the term loan facility of $2.5 million are due on the first day of each quarter beginning April1, 2015, with any remaining balance due in December 2019. Borrowings under the revolving credit facility carry the same maturity date as the $50.0 million term loan. Mandatory prepayments include net cash proceeds from certain asset sales, 100% of the net cash proceeds of any subordinated debt and 50% of the net cash proceeds of certain equity transactions, excluding the cash proceeds from any permitted senior unsecured debt, any equity interests issued under certain stock option or employer incentive plans, and any other equity interests issued if consolidated senior secured debt to EBITDA is less than or equal to 2.00 to 1.00.

	The Senior Debt has priority in repayment to all other outstanding debt except certain senior secured notes that we are permitted to issue in the future. We have granted our lenders a security interest in substantially all of our assets, including intellectual property, pursuant to a security agreement and an intellectual property security agreement, except that the security interest shall apply only after the total debt to EBITDA ratio is greater than or equal to 1:50 to 1:00. We are subject to complying with certain financial covenants, including minimum trailing 12 month EBITDA levels, total debt to EBITDA ratio, a fixed charge coverage ratio and a consolidated senior secured debt to EBITDA ratio (each as more fully described in the second amended and restated revolving credit and term loan agreement). The second amended and restated revolving credit and term loan agreement contains customary affirmative and negative covenants and prohibits, among other things and subject to certain exceptions, the incurrence of additional debt, payment of other debt obligations, incurrence of liens, acquisitions of businesses, capital expenditures, sales of businesses or assets, payment of dividends, repurchases of our capital stock, making loans or advances and certain other restrictions. The exceptions to the foregoing include capital expenditures of up to $20 million in any fiscal year and our right to repurchase up to $100 million of our outstanding capital stock, each subject to certain conditions set forth in the second amended and restated revolving credit and term loan agreement. The second amended and restated revolving credit and term loan agreement also contains customary events of default including, among others, payment defaults, breaches of covenants, bankruptcy and insolvency events, cross defaults with certain material indebtedness, judgment defaults, change of control and breaches of representations and warranties.

	Seller Notes

	In July 2013, our wholly owned subsidiary, RetailMeNot, France, issued seller notes payable, or Ma-Reduc Notes, in connection with our acquisition of ABCYNE. The Ma-Reduc Notes had an aggregate principal amount of €3.75 million, translated to $5.2 million on our balance sheet as of December 31, 2013 and matured in July 2014. The Ma-Reduc Notes were repaid in full in July 2014.

	In March 2013, we issued seller notes payable, Actiepagina Notes, in connection with our acquisition of Actiepagina B.V. The Actiepagina Notes had an aggregate principal amount of $1.2 million and matured in September 2014. The Actiepagina Notes were repaid in full in September 2014.

	Other Notes

	In conjunction with our acquisition of Miwim (Bons-de-Reduction.com and Poulpeo.com) in May 2012, we entered into deferred compensation arrangements with the former owners of Miwim, at which time we issued promissory notes, or the Miwim Notes, with an aggregate principal amount $3.5 million. We paid $1.75 million of the principal, along with accompanying interest, during 2013, and we paid the remaining $1.75 million upon maturity in May 2014.

	Operating Leases
	We lease office space, including our corporate headquarters in Austin, Texas, under non-cancelable operating leases. Rent expense under these operating leases was $4.9 million, $3.2 million and $1.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Certain of these lease arrangements have renewal or expansion options and adjustments for market provisions, such as free or escalating base monthly rental payments. Amounts reported in the table below are reported net of rent concessions. We recognize rent expense under such lease arrangements on a straight-line basis over the initial term of the lease. The difference between the straight-line expense and the cash paid for rent has been recorded as deferred rent.
	We are responsible for paying our proportionate share of the actual operating expenses and real estate taxes under certain of these lease agreements. These operating expenses are not included in the table below.

	Legal Matters
	From time to time, we may be involved in litigation relating to claims arising in the ordinary course of business. Management believes that there are no claims or actions pending or threatened against the Company, the ultimate disposition of which would have a material impact on our consolidated financial position, results of operations or cash flows.
	Employment Agreements
	We have entered into employment and change of control arrangements with certain of our executive officers and with certain employees in Europe.
	Indemnification
	In the normal course of business, to facilitate transactions related to our operations, we indemnify certain parties, including lessors, service providers and, from time to time, retailers and performance marketing networks with respect to certain matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations or covenants, or other claims, including intellectual property infringement claims made against those certain parties by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, we have entered into indemnification agreements with our officers and directors, and our bylaws contain similar indemnification obligations.

	Common Stock
	All share and per share information for all periods presented has been adjusted to reflect the effect of a four-for-one reverse stock split in June 2013. Our certificate of incorporation authorizes shares of stock as follows: 150,000,000 shares of Series 1 common stock, 6,107,494 shares of Series 2 common stock, and 10,000,000 shares of preferred stock. The common and preferred stock have a par value of $0.001 per share. As of December 31, 2014 and 2013, 54,253,452 and 46,569,376 shares of Series 1 common stock were outstanding, respectively. As of December 31, 2014 and 2013, zero and 6,107,494 shares of Series 2 common stock were outstanding, respectively.
	In March 2014, the holders of all 6,107,494 shares of Series 2 common stock outstanding converted such shares into 6,107,494 fully paid and nonassessable shares of Series 1 common stock. Following such conversion, no shares of Series 2 common stock remained outstanding.
	Each share of common stock is entitled to one vote at all meetings of stockholders, except each share of Series 2 common stock is not entitled to vote in connection with the election of the members of our board of directors. The number of authorized shares of common stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of shares of capital stock of the Company representing a majority of the votes represented by all outstanding shares of capital stock of the Company entitled to vote. The holders of common stock are also entitled to receive dividends, when, if and as declared by our board of directors, whenever funds are legally available therefore, subject to the priority rights of any outstanding preferred stock.
	Initial Public Offering
	On July 24, 2013, we completed our initial public offering of 10,454,544 shares of Series 1 common stock, at a price of $21.00 per share, before underwriting discounts and commissions. We sold 4,545,454 of such shares and existing stockholders sold an aggregate of 5,909,090 of such shares, including 1,363,636 shares sold by selling stockholders as a result of the underwriters’ exercise of their over-allotment option to purchase additional shares. Our initial public offering generated net proceeds to us of approximately $85.4 million, after deducting underwriting discounts and commissions. Expenses incurred by us for our initial public offering were approximately $3.4 million and were recorded against the net proceeds received by us from our initial public offering. We did not receive any proceeds from the sale of shares by the selling stockholders in our initial public offering.
	Follow-on Offering
	On December 16, 2013, we completed our follow-on offering of 7,207,207 shares of Series 1 common stock, at a price of $26.00 per share before underwriting discounts and commissions. We sold 2,000,000 of such shares and existing stockholders sold an aggregate of 5,207,207 of such shares, including 940,070 shares sold by selling stockholders as a result of the underwriters’ exercise of their option to purchase additional shares. The offering generated net proceeds to us of $49.1 million, after deducting underwriting discounts and commissions. Expenses incurred by us for the follow-on offering were approximately $0.6 million and were recorded against the proceeds received from the follow-on offering. We did not receive any proceeds from the sale of shares by the selling stockholders in the follow-on offering.
	Stock-Based Compensation
	In July 2013, our board of directors and stockholders approved our 2013 Equity Incentive Plan (the “2013 Plan”) and our 2013 Employee Stock Purchase Plan (the “2013 Purchase Plan”). When the 2013 Plan took effect, all shares available for grant under our 2007 Stock Plan, as amended (the “2007 Plan”), were transferred into the share pool of the 2013 Plan. Subsequent to our initial public offering, we have not granted, and will not grant in the future, any additional awards under the 2007 Plan. However, the 2007 Plan will continue to govern the terms and conditions of all outstanding equity awards granted under the 2007 Plan.
	2013 Equity Incentive Plan
	Under our 2013 Plan, the following awards types may be granted: stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units and other cash-based or stock-based awards. To date we have granted non-statutory stock options and restricted stock units. Restricted stock units represent rights to receive shares of our Series 1 common stock (or their value in cash) at a future date without payment of a purchase price. Holders of restricted stock units have no voting rights or rights to receive cash dividends unless and until shares of Series 1 common stock are issued in settlement of such awards. The compensation committee of our board of directors, or a committee appointed by the compensation committee, determines the term of the option, option price, number of shares for which each option and restricted stock unit is granted, whether restrictions will be imposed on the shares subject to the option or restricted stock unit, and the vesting period for each option and restricted stock unit. Awards granted under the 2013 Plan generally vest over four years. The term of each option is no more than ten years from grant date.

	2007 Stock Plan
	Options granted under the 2007 Plan are either incentive stock options or nonstatutory stock options. Our board of directors determined the term of the option, option price, number of shares for which each option was granted, whether restrictions were imposed on the shares subject to the option, and the vesting period for each option. Generally, options become 25% vested after one year of service, with the remaining 75% vesting on a pro-rata basis over the remaining three years. The term of each option is ten years from grant date.
	Stock-based compensation expense for all employee share-based payment awards is based upon the grant date fair value. We recognize compensation costs, net of estimated forfeitures, on a straight-line basis over the requisite service period of the award. Forfeiture rates are estimated at grant date based on historical experience and adjusted in subsequent periods for differences in actual forfeitures from our previous estimates. We recorded $24.5 million, $10.5 million and $4.0 million of stock-based compensation expense for the years ended December 31, 2014, 2013 and 2012, respectively. We include stock-based compensation expense in cost and expenses consistent with the classification of respective employees’ cash compensation in the consolidated statements of operations.
	The fair value of stock options granted during the years ended December 31, 2014, 2013 and 2012 was estimated on the grant date using the Black-Scholes-Merton option pricing model. The weighted-average assumptions for stock options granted are outlined in the following table:


			Year Ended December 31,
			2014				2013				2012
	Expected volatility			56.39	%			60.27	%			64.46	%
	Expected term (in years)			6				6				6
	Risk-free rate of return			1.94	%			1.34	%			0.95	%
	Expected dividend yield			—				—				—
	Due to our short history as a public company, our expected volatility is based on the volatility of comparable publicly traded entities. The expected term represents the period of time the stock options are expected to be outstanding and is based on the “simplified method”. We used the “simplified method” due to the lack of sufficient historical exercise data to provide a reasonable basis upon which to otherwise estimate the expected life of the stock options. The risk-free interest rate assumptions we use are based on observed market interest rates appropriate for the term of our stock options.

	The following tables summarize the stock option activity of our 2007 Plan and 2013 Plan for the years ended December 31, 2014, 2013 and 2012:

Earnings Per Share [Abstract]
Earnings Per Share	10. Earnings Per Share
	Basic and diluted net income per common share is presented in conformity with the two-class method required for participating securities. Prior to our initial public offering, holders of preferred stock were each entitled to receive cumulative dividends payable prior and in preference to any dividends on any shares of our common stock. In the event a dividend was paid on common stock, the holders of preferred stock were entitled to a proportionate share of any such dividend as if they were holders of common stock (on an as-if converted basis). Accordingly, all of our outstanding series of preferred stock were considered to be participating securities. The holders of our preferred stock did not have a contractual obligation to share in our losses; therefore, no amount of total undistributed loss is allocated to preferred stock.
	The rights of the holders of Series 1 and Series 2 common stock are identical, except with respect to voting. Each share of Series 1 and Series 2 common stock is entitled to one vote per share; however holders of Series 2 common stock are not entitled to vote in connection with the election of the members of our board of directors. Shares of Series 2 common stock may be converted into shares of Series 1 common stock at any time at the option of the stockholder. As of December 31, 2014, no shares of Series 2 common stock were outstanding.
	Under the two-class method, basic net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period preferred stock dividends, between common stock and preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. Diluted net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding, including potential dilutive shares of common stock assuming the dilutive effect of outstanding stock options and warrants using the treasury stock method or if-converted method, whichever is more dilutive.

	The following table sets forth the computation of basic and diluted earnings per share of common stock (in thousands, except per share amounts):


		Year Ended December 31,

Fair Value Disclosures [Abstract]
Fair Value Measurements	11. Fair Value Measurements
	Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Generally accepted accounting principles set forth a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The three tiers are Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop our own assumptions.
	Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands):

	Liabilities:

	Money market funds are reported on our consolidated balance sheets as cash and cash equivalents, and derivative instruments are reported on our consolidated balance sheets as accrued expenses and other current liabilities. The fair value of our derivative instruments has been determined using pricing models that take into account the underlying contract terms, as well as all applicable inputs, such as interest rate yield curves and currency rates. Our other financial instruments consist primarily of accounts receivable, accounts payable, accrued liabilities and notes payable. The carrying value of these assets and liabilities approximate their respective fair values as of December 31, 2014 and 2013 due to the short-term maturities, or in the case of our long-term notes payable, based on the variable interest rate feature. As of December 31, 2014, 2013 and 2012 no significant fair value adjustments were required for nonfinancial assets and liabilities.

In July 2013, our wholly owned subsidiary, RetailMeNot, France, acquired 100% of the outstanding capital stock of Ma-Reduc.com. See Note 3, “Acquisitions”. A net deferred tax liability of approximately $2.5 million was recorded primarily related to acquired intangibles.

In October 2013, we acquired 100% of the outstanding stock of YSL Ventures, Inc. See Note 3, “Acquisitions”. A net deferred tax liability of approximately $0.3 million was recorded primarily related to acquired intangibles, offset by net operating loss and research and development tax credit carryforwards.



A valuation allowance is established if, based on the Company’s review of both positive and negative evidence, it is more likely than not that all or a portion of the deferred tax asset will not be realized. We recorded a valuation allowance of approximately $1.0 million at December 31, 2014, related to the uncertainty of the utilization of certain state research and development tax credit carryforwards.

As of December 31, 2014, we had federal net operating loss carryforwards of $0.9 million, federal research and development tax credit carryforwards of $22,000 and state research and development tax credit carryforwards of $1.3 million. These carryforwards expire between 2031 and 2034 if not utilized. As of December 31, 2014 and 2013, no provision has been made for U.S. income taxes and foreign withholding taxes related to undistributed earnings of our foreign subsidiaries, as those earnings are considered to be permanently reinvested outside the United States. As of December 31, 2014, we did not have an unrecognized deferred tax liability related to undistributed earnings of our foreign subsidiaries, as we have incurred foreign taxes during our 2014 global corporate restructuring which, if repatriated, would generate foreign tax credits sufficient to reduce additional taxes on repatriated earnings. As of December 31, 2013, the unrecognized deferred tax liability related to undistributed earnings of our foreign subsidiaries was $3.5 million.

The exercise of certain of our stock options results in taxable compensation, which is includable in the taxable income of the exercising option holder and which we can deduct from our taxable income for federal and state income tax purposes. Such compensation results from increases in the fair value of our common stock subsequent to the date of grant of the exercised stock options. Option-related excess tax benefits (tax deduction over cumulative book deduction) are recorded as an increase to additional paid-in capital, while option-related tax deficiencies (cumulative book deduction over tax deduction) are recorded as a decrease to additional paid-in capital to the extent of our additional paid-in capital option pool, then to the income tax provision. During the years ended December 31, 2014 and 2013, we recorded increases to additional paid-in capital of $11.1 million and $2.0 million, respectively, offset by reductions in current taxes payable.

We follow the guidance on accounting for uncertainty in income taxes, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The aggregate changes in the balance of unrecognized tax benefits for the years ended December 31, 2014 and 2013 were as follows, excluding interest and penalties (in thousands):



Balance at December 31, 2012		$	—
Increases for tax positions related to the current year			282
Increases for tax positions related to prior years			948

Balance at December 31, 2013		$	1,230
Increases for tax positions related to the current year			2,269
Increases for tax positions related to prior years			513
Decreases for tax positions related to prior years			(73	)
Lapses in statutes of limitations			(10	)

Balance at December 31, 2014		$	3,929


Included in the balance of unrecognized tax benefits at December 31, 2014 are $0.3 million of unrecognized tax benefits that are offset against related deferred tax assets for which a valuation allowance exists. If we were to recognize the unrecognized tax benefits, the benefit would be offset by a change in the valuation allowance and would not have an impact on the effective tax rate.

Our practice is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. In 2014, 2013 and 2012, we recognized interest and penalties of $0.1 million, $0.3 million, and $0.0 million, respectively, within income tax expense on our consolidated statements of operations. Amounts for interest and penalties accrued are included within the related tax liability line in the consolidated balances sheets and were $0.4 million and $0.3 million for the years ended December 31, 2014 and 2013, respectively.

We file U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. As of December 31, 2014, in the United States, the tax years 2011 through 2014 remain open to examination in the federal jurisdiction and most state jurisdictions. The Internal Revenue Service has not conducted an examination for any tax year. Additionally, various foreign income tax returns are subject to examinations for years 2011 through 2014. For uncertain tax positions as of December 31, 2014, we do not anticipate that the total amounts of unrecognized tax benefits will significantly increase or decrease within the coming year.

As of December 31, 2014, the unamortized tax effects of corporate restructuring transactions of $0.8 million and $2.3 million are included within “Prepaids and other current assets, net “ and “Other assets, net,” respectively, on the consolidated balance sheet. As of December 31, 2014, the estimated future amortization of the tax effects of corporate restructuring transactions to income tax expense is $0.8 million for 2015 and $2.3 million, cumulatively, for the years 2016 through 2020. These amounts exclude the benefits, if any, for tax deductions in other jurisdictions that we may be entitled to as a result of the related corporate restructuring transactions.
