	The Company
	Sizmek Inc. ("Sizmek," the "Company," "we," "us," and "our"), a Delaware corporation formed in 2013, operates a leading independent global online ad campaign management and distribution platform as measured by the number of advertising impressions served and the number of countries in which we serve customers. Our revenues are principally derived from services related to online advertising. We help advertisers, agencies and publishers engage with consumers across multiple online media channels (mobile, display, rich media, video and social) while delivering efficient, impactful and measurable ad campaigns. We connect 17,000 advertisers and 3,500 agencies to audiences in about 60 countries, serving more than 1.4 trillion impressions a year.
	Separation from Digital Generation, Inc.
	Prior to February 7, 2014, we operated as the online segment of Digital Generation, Inc. ("DG"), a leading global television and online advertising management and distribution business. On February 7, 2014, pursuant to the terms of the Agreement and Plan of Merger, dated as of August 12, 2013 (the "Merger Agreement"), by and among Extreme Reach, Inc. ("Extreme Reach"), Dawn Blackhawk Acquisition Corp., a wholly-owned subsidiary of Extreme Reach ("Acquisition Sub"), and DG, all of our issued and outstanding shares of common stock, par value $0.001 per share ("Sizmek Common Stock") were distributed by DG pro rata to its stockholders (the "Spin-Off") with the DG stockholders receiving one share of Sizmek Common Stock for each share of DG common stock ("DG Common Stock") they held. Immediately after the distribution of the Sizmek Common Stock, pursuant to the Merger Agreement, Acquisition Sub merged with and into DG with DG as the surviving corporation (the "Merger") and all of the outstanding shares of DG Common Stock was converted into the right to receive $3.00 per share, and DG became a wholly-owned subsidiary of Extreme Reach. Prior to the Spin-Off, pursuant to the Separation and Redemption Agreement and related documents, DG contributed to us all of the business and operations of its online advertising segment, all of DG's cash, most of the working capital from its television segment, and certain other corporate assets; and we agreed to indemnify DG and affiliates of DG (including Extreme Reach) for all pre-closing liabilities of DG, including stockholder litigation, tax obligations, and employee liabilities. Sizmek now operates as a separate, stand-alone publicly-traded company in the online advertising services business segment.
	Carve-out Financial Statements Prior to Spin-Off
	Prior to our Spin-Off from DG on February 7, 2014, our combined financial statements were derived from the consolidated financial statements and accounting records of DG. These statements reflected the combined historical results of operations, financial position and cash flows of DG's online business primarily conducted through MediaMind Technologies Inc., EyeWonder, LLC, Peer39, Inc., and Unicast EMEA, Ltd., and an allocable portion of DG's corporate costs. Prior to the Spin-Off, our financial statements are presented as if such businesses had been combined for all periods presented.
	All intercompany transactions have been eliminated. All intercompany transactions between us and DG have been included in these combined financial statements and are considered to be effectively settled for cash in the combined financial statements at the time the transaction is recorded. The total net effect of the settlement of these intercompany transactions is reflected in the combined statements of cash flows as a financing activity and in the combined balance sheet as "Parent company investment."
	For periods prior to our Spin-Off on February 7, 2014, the combined financial statements include expense allocations for (1) certain corporate functions historically provided by DG, including, but not limited to, finance, audit, legal, information technology, human resources, communications, compliance, and shared services; (2) employee benefits and incentives; and (3) share-based compensation. These expenses have been allocated to us on the basis of direct usage when identifiable, with the remainder allocated on a pro-rata basis of combined revenues, headcount or other measures of the Company and DG. We consider the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to, or the benefit received by, us during the periods presented. The allocations may not, however, reflect the expense we would have incurred as an independent, publicly-traded company for the periods presented. We benefited from sharing the corporate cost structure of DG rather than incurring such costs ourselves on a stand-alone basis. For 2013, DG reported corporate overhead (excluding share-based compensation) of $24.2 million. The amount of DG's corporate overhead that was allocated to us for 2013 in these carve-out financial statements was $9.1 million, in accordance with the allocation principles for preparing carve-out financial statements (see Note 11 for a summary of DG's expense allocations to us for 2014, 2013 and 2012). As a result, the 2013 carve-out financial statements include corporate overhead expenses which represent about 37% of DG's 2013 total corporate overhead. The majority of the pre Spin-Off expense allocations were charged to general and administrative expense. For the period subsequent to the Spin-Off, general and administrative expense as a percentage of revenues has been comparable to the corresponding period of the prior year. Accordingly, while we benefited from sharing DG's cost structure prior to the Spin-Off, since the Spin-Off we have been able to control our corporate overhead expenses to a level reasonably consistent with the pre Spin-Off periods.
	Historically, DG used a centralized approach to cash management and the financing of its operations. Prior to the Spin-Off, the majority of our cash was transferred to DG on a daily basis, and DG funded our operating and investing activities as needed. Cash transfers to and from DG's cash management accounts are reflected in "Parent company investment."
	Prior to the Spin-Off, the combined financial statements included certain assets and liabilities that were held at the DG corporate level but were specifically identifiable or otherwise allocable to us. The cash and cash equivalents held by DG at the corporate level were not specifically identifiable to us and therefore were not allocated to us for any of the periods presented prior to the Spin-Off; however, at the Spin-Off date, cash and working capital associated with DG's TV business were contributed to us. Cash and cash equivalents in our combined balance sheet prior to the Spin-Off primarily represents cash held locally by entities included in our combined financial statements. DG's third-party debt and the related interest expense have not been allocated to us for any period as we were not the legal obligor and those amounts were paid off on or about February 7, 2014 as part of DG's Merger with Extreme Reach.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies
	2. Summary of Significant Accounting Policies
	Basis of Presentation
	The consolidated and combined financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and include the accounts of our wholly-owned, and majority-owned and controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. For the periods prior to the Spin-Off, the carve-out financial statements have been prepared on a basis that management believes to be reasonable to reflect the financial position, results of operations and cash flows of the Company's operations, including portions of DG's corporate costs and administrative shared services.
	Revenue Recognition
	We derive revenue primarily from volume-based fees for using our online ad serving platform. We recognize revenue only when all of the following criteria have been met:
	•	Persuasive evidence of an arrangement exists,
	•	Delivery has occurred or services have been rendered,
	•	Our price to the customer is fixed or determinable, and
	•	Collectability is reasonably assured.
	We offer online advertising campaign management and deployment products. These products allow publishers, advertisers, and their agencies to manage the process of deploying online advertising campaigns. We charge our customers on a cost per thousand ("CPM") impressions basis, and recognize revenue when the impressions are served. In some instances, we charge a flat fee for a campaign and recognize revenue ratably over the period of the campaign.
	We also offer programmatic managed services. In providing these services, we enter into arrangements with third parties to facilitate our customer's online advertising. The determination of whether we should recognize revenue on a gross or net basis is based on an assessment of whether we are acting as the principal, or an agent, in the transaction. In determining whether we are acting as the principal or an agent, we follow the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because we are the primary obligor in the arrangement and we are responsible for (i) selecting and contracting with third party suppliers for the purchase of inventory, (ii) managing the advertising process including selecting or advising on campaign parameters, monitoring campaign results, and adjusting parameters and modifying publishers throughout the campaign to optimize results, (iii) establishing the selling price, and (iv) assuming credit risk in the transaction, we act as the principal in these arrangements and therefore we report revenues earned and costs incurred on a gross basis.
	For 2014, 2013 and 2012, we reported revenues and cost of revenues from programmatic managed services as follows (dollars in thousands):

			Years Ended December 31,
			2014			2013			2012
	Revenues		$	16,737		$	10,530		$	4,695
	% of total revenues			9.8	%		6.5	%		3.3	%
	Cost of revenues(1)			11,818			7,915			3,924

	Net		$	4,919		$	2,615		$	771




	-1	Includes the cost of purchasing media, but does not include personnel and other overhead related costs that are recorded in cost of revenues.
	Seasonality
	Our business is seasonal. Revenues tend to be the highest in the fourth quarter as a large portion of our revenues follow the advertising patterns of our customers.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the recoverability and useful lives of long-lived assets, the adequacy of our allowance for doubtful accounts and credit memo reserves, contingent consideration and income taxes. We base our estimates on historical experience, future expectations and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
	In 2014 and 2012, we recorded goodwill impairment charges of $98.2 million and $219.6 million, respectively. See Note 5 for a discussion of the risk of a future impairment of our goodwill.
	Effective November 1, 2014, we shortened the estimated remaining useful life of our Sizmek MDX platform assets from an average of 46 months to 20 months in anticipation of our new platform (which is currently in development). We anticipate the new platform will be operational by the end of 2015 and we expect to retire our existing platform by mid-2016. As a result, we recorded additional depreciation expense of $0.6 million during 2014, which increased our net loss and loss per share by $0.5 million and $0.02, respectively.
	Cash and Cash Equivalents
	Cash equivalents consist of liquid investments with original maturities of three months or less at the date of acquisition. We maintain substantially all of our cash and cash equivalents with a few major financial institutions in the United States and Israel.
	Restricted Cash
	Restricted cash principally relates to (i) funding of Israeli statutory employee compensation, (ii) required cash balances for foreign currency forward contracts and options, and (iii) security deposits on office leases.
	Accounts Receivable and Allowances
	Accounts receivable are recorded at the amount invoiced, provided the revenue recognition criteria have been met, less allowances for doubtful accounts and credit memos. We maintain allowances for doubtful accounts and credit memos on an aggregate basis, at a level we consider sufficient to cover estimated losses in the collection of our accounts receivable and credit memos expected to be issued. The allowance is based primarily on known troubled accounts, the collectability of specific customer accounts and customer concentrations, with consideration given to current economic conditions and trends. We charge off accounts that remain uncollected after reasonable collection efforts are made.
	Property and Equipment, Net
	Property and equipment are stated at cost. Depreciation is computed over the estimated useful lives of the assets using the straight-line method. Leasehold improvements are amortized on a straight-line basis over the shorter of the remaining lease term plus expected renewals or the estimated useful life of the asset. The estimated useful lives of our property and equipment (excluding property and equipment acquired in a business combination) are principally as follows:

	Category		Useful Life
	Software—internally developed software costs		2 - 5 years
	Software—purchased		3 years
	Computer equipment		3 years
	Furniture and fixtures		6 - 14 years
	Network equipment		3 years
	Machinery and equipment		3 years
	Long-Term Investments
	We acquired available for sale equity securities with an original cost of $1.2 million. During 2012, these securities declined in value to about $0.3 million. We determined the decline in value was other than temporary and, as a result, recorded an impairment charge of $0.9 million (cost basis of $1.2 million less fair value of $0.3 million). Also during 2012, we made a $1.5 million equity investment in a company that was developing a web-based audience and content measurement platform. Later in 2012, we determined that our investment was impaired and wrote-off the investment. These two charges are recorded in "other (income) and expense, net" in the accompanying statements of operations.
	Leases
	We lease certain properties under operating leases, generally for periods of 3 to 10 years. Some of our leases contain renewal options and escalating rent provisions. For leases that provide for escalating rent payments or free-rent occupancy periods, we recognize rent expense on a straight-line basis over the non-cancelable lease term plus option renewal periods where failure to exercise an option appears, at the inception of the lease, to be reasonably assured. Deferred rent is included in both accrued liabilities and other non-current liabilities in the accompanying balance sheets. See "Leases" under Note 12 for additional information regarding our lease commitments.
	Software Development Costs
	Costs incurred to create software for internal use are expensed during the preliminary project stage and only costs incurred during the application development stage are capitalized. Upon placing the completed project in service, capitalized software development costs are amortized over the estimated useful life, which generally ranges from two to five years.
	Depreciation of capitalized software development costs for the years ended December 31, 2014, 2013 and 2012 was $4.3 million, $1.9 million and $2.9 million, respectively. The net book value of capitalized software development costs was $23.0 million and $13.3 million as of December 31, 2014 and 2013, respectively.
	Assets and Liabilities of DG's TV Business
	Pursuant to the Separation and Redemption Agreement (see Note 1), DG contributed to us substantially all of its television business current assets and certain other assets existing on February 7, 2014, and we agreed to assume substantially all of DG's television business liabilities that existed on February 7, 2014 or were attributable to periods up to and including February 7, 2014. The net assets contributed were recorded at $78.5 million. The details of these assets and liabilities outstanding as of December 31, 2014 were as follows (in thousands):

	Description		December 31, 2014
	Current assets of television business:
	Income tax receivables		$	1,943
	Trade accounts receivable			367
	Springbox revenue sharing			160

Total		$	2,470

Trade accounts payable		$	165
Accrued liabilities			230

Total		$	395


Non-current liabilities of television business:
Uncertain tax positions		$	260


Derivative Instruments
We enter into foreign currency forward contracts and options to hedge a portion of the exposure to the variability in expected future cash flows resulting from changes in related foreign currency exchange rates between the New Israeli Shekel ("NIS") and the U.S. Dollar. These transactions are designated as cash flow hedges, as defined by Accounting Standards Codification ("ASC") Topic 815, "Derivatives and Hedging."
ASC Topic 815 requires that we recognize derivative instruments as either assets or liabilities in our balance sheet at fair value. These contracts are Level 2 fair value measurements in accordance with ASC Topic 820, "Fair Value Measurements and Disclosures." For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss), net of taxes, and reclassified into earnings (various operating expenses) in the same period or periods during which the hedged transaction affects earnings.
Our cash flow hedging strategy is to hedge against the risk of overall changes in cash flows resulting from certain forecasted foreign currency rent and salary payments during the next twelve months. We hedge portions of our forecasted expenses denominated in the NIS with a single counterparty using foreign currency forward contracts and options. At December 31, 2014, we had $14.3 million notional amount of foreign currency forward contracts and options outstanding that had a net fair value liability balance of $0.1 million ($0.2 million liability, net of a $0.1 million asset). The net liability is included in "accrued liabilities" and is expected to be recognized in our results of operations in the next twelve months. At December 31, 2013, we had $5.2 million notional amount of foreign currency forward contracts and options outstanding that had a net fair value asset balance of $0.1 million ($0.1 million asset, net of a $0.0 million liability). The vast majority of any gain or loss from hedging activities is included in our various operating expenses. As a result of our hedging activities, we incurred the following gains and losses in our results of operations (in thousands):

		Years Ended

		2014			2013			2012
Hedging gain (loss) recognized in operations		$	115		$	865		$	(573	)
It is our policy to offset fair value amounts recognized for derivative instruments executed with the same counterparty. In connection with our foreign currency forward contracts and options and other banking arrangements, we have agreed to maintain $1.5 million of cash in bank accounts with our counterparty, which we classify as restricted cash on our balance sheet.

Goodwill
Goodwill represents the excess of the purchase price over the fair value of net identifiable assets acquired. We test goodwill for potential impairment at the reporting unit level on an annual basis, or more frequently if an event occurs or circumstances exist indicating goodwill may not be recoverable. Such events or circumstances may include operating results lower than previously forecasted or declines in future expectations of our operating results, or other significant negative industry trends. In evaluating goodwill for potential impairment, we perform a two-step process that begins with an estimate of the fair value of each reporting unit that contains goodwill (presently, we operate as a single reporting unit). We use a variety of methods, including discounted cash flow models, to determine fair value. In the event a reporting unit's carrying value exceeds its estimated fair value, evidence of a potential impairment exists. In such a case, the second step of the impairment test is required, which involves allocating the fair value of the reporting unit to its assets and liabilities, with the excess of fair value over allocated net assets representing the implied fair value of its goodwill. An impairment loss is measured as the amount, if any, by which the carrying value of a reporting unit's goodwill exceeds its implied fair value. During 2014 and 2012 we recorded goodwill impairment losses of $98.2 million and $219.6 million, respectively. See Note 5 for a discussion of the risk of a future impairment of our goodwill.
Long-Lived Assets
We assess our long-lived assets (other than goodwill), including acquired identifiable intangibles, for potential impairment whenever certain triggering events occur. Events that may trigger an impairment review include the following:
•	significant underperformance relative to historical or projected future operating results;
•	significant changes in the use of our assets or the strategy for our overall business; and
•	significant negative industry or economic trends.
If we determine the carrying value of our long-lived or intangible assets may not be recoverable based upon the occurrence of a triggering event, we assess the recoverability of these assets by determining whether amortization of the asset balance over its remaining life can be recovered through undiscounted future operating cash flows. Any impairment is determined based on a projected discounted cash flow model using a discount rate reflecting the risk inherent in the projected cash flows.
We determine the useful lives of our identifiable intangible assets after considering the specific facts and circumstances related to each asset. Factors considered when determining useful lives include the contractual term of any agreement, the history of the asset, our long-term strategy for using the asset, any laws or other local regulations that could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have finite lives are generally amortized on a straight-line basis over their useful lives which generally range from 3 to 12 years. See "Intangible Assets" under Note 5 for additional information.
Foreign Currency Translation and Measurement
We translate the assets and liabilities of our non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using the average exchange rates that were in effect during the period. Gains and losses from these translations are recognized in foreign currency translation, a component of accumulated other comprehensive income (loss) and part of stockholders' equity (business capital prior to the Spin-Off). Gains or losses from measuring foreign currency transactions into the functional currency are included in our statements of operations. For 2014, 2013 and 2012, we recognized foreign currency transaction gains and (losses) of ($1.2) million, $0.1 million and ($0.4) million, respectively.
Research and Development Expenses
Research and development expenses mainly include costs associated with maintaining our technology platform and are expensed as incurred.
Merger, Integration and Other Expenses
Merger, integration and other expenses reflect the expenses incurred in (i) DG's Merger with Extreme Reach and our Spin-Off from DG, (ii) acquiring or disposing of a business, (iii) integrating an acquired operation (e.g., severance pay, office closure costs) into the Company and (iv) certain other items of income or expense not deemed to be part of our core operations. A summary of our merger, integration and other expenses is as follows (in thousands):

Description		2014			2013			2012
Merger and Spin-Off(1)		$	5,507		$	4,078		$	—
Severance			1,200			569			2,970
Integration and restructuring costs			2,400			321			1,655
MediaMind preacquisition liability			—			720			—
Acquisition legal and due diligence fees			275			—			644
Recovery of TV business assets(2)			(3,078	)		—			—
Other			—			189			683

Total		$	6,304		$	5,877		$	5,952




-1	Merger and Spin-Off includes costs incurred prior to the transactions while DG was evaluating strategic alternatives. See discussion of Merger and Spin-Off under "Separation from Digital Generation, Inc." in Note 1.
-2	Represents a reduction in expense due to realizing more TV net assets than originally estimated at the time of the Spin-Off.
Severance costs primarily relate to consolidating the workforces of MediaMind, EyeWonder, and Unicast and eliminating redundancy. All costs shown above were paid in the period the expense was recognized, or shortly thereafter. As of December 31, 2014, our integration efforts were substantially complete.
Share-Based Payments
Subsequent to the Spin-Off, the compensation committee of our board of directors authorizes the issuance of stock options, time-based restricted stock units ("RSUs") and performance-based RSUs to our employees, directors and consultants. The committee approves grants only out of shares previously authorized by our stockholders.
We recognize compensation expense based on the estimated fair value of the share-based payments. The fair value of our RSUs is based on the closing price of our common stock the day prior to the date of grant. The fair value of our stock options is calculated using the Black-Scholes option pricing model. Share-based awards that do not require future service are expensed immediately. Share-based awards that only require future service are amortized over the relevant service period on a straight-line basis. Share-based awards that require satisfaction of performance conditions, such as performance-based RSUs, are amortized over the performance period provided it is probable that the performance conditions will be satisfied. Subsequently, if the performance conditions are no longer probable of achievement, then all previously recognized compensation expense for that award will be reversed.
Prior to the Spin-Off, we participated in DG's compensation programs that included equity-based incentive awards. Those equity-based awards related to shares of DG's common stock, not to our equity. For DG equity awards, we recognized an allocated cost equal to the cost recognized by DG. Allocations of share-based payments also arose from acquisitions when DG agreed to assume the share-based obligations of the acquired company on our behalf; such as the case in our acquisition of MediaMind. In connection with completing the Merger and Spin-Off, all of DG's outstanding equity awards became fully vested and, to the extent the award had an intrinsic value, were converted into shares of DG stock. Equity awards with no intrinsic value were cancelled. Following the Spin-Off, we did not assume any equity award previously issued by DG.
We recognized $9.4 million, $6.4 million and $8.9 million in share-based compensation expense related to stock options, restricted stock and RSUs during the years ended December 31, 2014, 2013 and 2012, respectively. For 2014, $2.9 million relates to our equity awards and $6.5 million relates to the allocated cost of DG's equity awards. See Note 10.
Income Taxes
Subsequent to the Spin-Off, we file our income tax returns on a stand-alone basis. Prior to the Spin-Off, our results of operations were included in the combined federal and state income tax returns of DG. For those periods, the income tax amounts reflected in the accompanying financial statements have been allocated to us based on taxable income (loss) directly attributable to us on a stand-alone basis. Management believes that the assumptions underlying the allocation of income taxes are reasonable. However, the amounts allocated for income taxes in the accompanying financial statements are not necessarily indicative of the amount of income taxes that would have been recorded had we operated as a separate, stand-alone entity during those periods. Prior to the Spin-Off, the U.S. federal and state tax losses generated by us were utilized by DG in its consolidated U.S. tax return. We are reflecting these U.S. federal and state tax losses as a distribution to DG for the year they were included in DG's U.S. tax returns.
We establish deferred income tax assets and liabilities for temporary differences between the tax and financial accounting bases of our assets and liabilities. The tax effects of such differences are recorded in the balance sheet at the enacted tax rates expected to be in effect when the differences reverse. A valuation allowance is recorded to reduce the carrying amount of deferred tax assets if it is more likely than not that all or a portion of the asset will not be realized. The ultimate realization of our deferred tax assets is primarily dependent upon generating taxable income during the periods in which those temporary differences become deductible. The need for a valuation allowance is assessed each year. We forecast the reversal of our deferred tax assets and liabilities in determining the need for a valuation allowance. For 2014, 2013 and 2012, we recorded a valuation allowance.
The tax balances and income tax expense recognized by us are based on our interpretation of the tax statutes of multiple jurisdictions and judgment. Differences between the anticipated and actual outcomes of these future tax consequences could have a material impact on our consolidated results of operations, financial position and cash flows.
We account for uncertain tax positions in accordance with ASC 740, which contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining whether the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any 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 reevaluate our income tax positions periodically to consider factors such as changes in facts or circumstances, changes in or interpretations of tax law, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in recognition of a tax benefit or an additional charge to the tax provision.
We include interest related to tax issues as part of income tax expense in our consolidated or combined financial statements. We record any applicable penalties related to tax issues within the income tax provision. See Note 8.
Business Combinations
Business combinations are accounted for using the acquisition method. The purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess purchase price over the fair value of the net identifiable assets acquired is recorded as goodwill. Operating results of an acquired business are included in our results of operations from the date of acquisition. See Note 3.
Financial Instruments and Concentration of Credit Risk
Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The vast majority of our cash and cash equivalents is held at large financial institutions in the United States and Israel that management believes to be of high credit quality. At certain financial institutions, our cash and cash equivalents regularly exceeds the federally insured limit. We have not experienced any losses on our cash and cash equivalents to date. We perform ongoing credit evaluations of our customers, generally do not require collateral and maintain a reserve for potential credit losses. We only recognize revenue when collection is reasonably assured. Our receivables are principally from advertising agencies and direct advertisers. Our receivables and the related revenues are not contingent on our customers' sales or collections. We believe the fair value of our accounts receivable approximate their carrying value. For the years ended December 31, 2014, 2013 and 2012, there was no single customer that accounted for more than 10% of our revenue. At December 31, 2014 and 2013, there was no single customer that accounted for more than 10% of our accounts receivables.
Israel Operations
The majority of our research and development activities and a large portion of our accounting functions are performed in Herzliya, Israel. In total, about 28% of our workforce is located in Israel. As a result, we are subject to risks associated with operating in the Middle East.
Recently Adopted and Recently Issued Accounting Guidance
Adopted
Effective January 1, 2014, we adopted ASU 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" on a prospective basis. ASU 2013-11 amends the accounting guidance related to the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. The guidance requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset where a net operating loss, a similar tax loss, or a tax credit carryforward exists and certain criteria are met. The adoption of ASU 2013-11 did not have a material impact on our financial statements.
Issued
In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 modifies revenue recognition guidance for GAAP. Previous revenue recognition guidance in GAAP comprised broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes resulted in different accounting for economically similar transactions. In contrast, International Accounting Standards Board ("IASB") provided limited guidance on revenue recognition. Accordingly, the FASB and IASB initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards ("IFRS"). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps:
Step 1: Identify the contract(s) with a customer.
Step 2: Identify the performance obligations in the contract.
Step 3: Determine the transaction price.
Step 4: Allocate the transaction price to the performance obligations in the contract.
Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.
For Sizmek, the amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. An entity shall adopt the amendments in ASU 2014-09 by either (i) retrospectively adjusting each prior reporting period presented or (ii) retrospectively adjusting for the cumulative effect of initially applying ASU 2014-09 at the date of initial adoption. We have not as yet determined (i) the extent to which we expect ASU 2014-09 will impact our reported revenues or (ii) the manner in which it will be adopted.

Acquisitions
	3. Acquisitions
	Over the last three years, we acquired four businesses in the media services industry. The objective of each transaction was to expand our product offerings, customer base, and global digital distribution network, and/or to better serve the advertising community. We expect to realize operating synergies from each of the transactions, or the acquired operation has created, or will create, opportunities for the acquired entity to sell its services to our customers. Both of these factors resulted in a purchase price that contributed to the recognition of goodwill. The acquisitions are summarized as follows:

	Business Acquired	Date of Closing			Net Assets			Form of
					Acquired			Consideration
					(in millions)
	Pixel		September 4, 2014		$	0.5		Cash/Note
	Aerify Media		August 11, 2014		$	6.3		Cash/Note
	Republic Project		October 4, 2013		$	1.4		Cash/Note
	Peer 39		April 30, 2012		$	15.7		Cash/Stock
	Each of the acquired businesses has been included in our results of operations since the date of closing. Accordingly, the operating results for the periods presented are not entirely comparable due to these acquisitions and related costs. In each acquisition, the excess of the purchase price over the fair value of the net identifiable assets acquired has been allocated to goodwill. A brief description of each acquisition is as follows:
	Pixel
	On September 4, 2014, we acquired all of the outstanding shares of Zestraco Investments Limited including its wholly-owned subsidiary PixelCo. D.O.O. ("Pixel") for $0.45 million in cash and a deferred payment obligation of $0.05 million which was paid in December 2014. Pixel performed advertising service operations principally for us prior to our purchase and had virtually no assets.
	The objective of the transaction was to bring in-house the group of technology service personnel that had been providing advertising operations service to us through a contract. We expect to realize operating synergies from this transaction. Pixel has been included in our results of operations since the date of closing. The $0.5 million purchase price was allocated to goodwill and is not deductible for income tax purposes. The purchase price allocation is final.
	Aerify Media
	On August 11, 2014, we acquired substantially all the assets and operations of privately-held Aerify Media LLC ("Aerify"), a firm specializing in mobile tracking and retargeting, for $5.625 million in cash and a $0.625 million deferred payment obligation due in one-year. Aerify's mobile in-app and web tracking technology expands our capabilities in the fast-growing mobile segment, adding both talent and technology to our platform.
	The objective of the transaction was to accelerate the development of our mobile technology in order to better serve the advertising community. We expect to realize operating synergies from this transaction. Aerify has been included in our results of operations since the date of closing.
	The $6.25 million purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values. We allocated $2.05 million to developed technology, $0.4 million to customer relationships and $3.8 million to goodwill. The developed technology and customer relationships acquired in the transaction are being amortized on a straight-line basis over 4 years and 5 years, respectively. The weighted average amortization period is 4.2 years. The goodwill and other intangible assets created in the acquisition are deductible for income tax purposes. For 2013, prior to our purchase, Aerify reported revenues of $3.1 million and a loss before income taxes of $0.6 million. For the period from the acquisition date through December 31, 2014, we recognized $0.9 million of revenues and a $0.4 million loss before income taxes from Aerify in our results of operations. The purchase price allocation is final.
	Purchase of Republic Project
	On October 4, 2013, we acquired the assets and operations of privately-held Republic Project, a cloud-based ad platform that enables agencies and brands to create, deliver and measure social and mobile rich media campaigns, for $1.1 million in cash, a $0.3 million deferred payment obligation and contingent consideration we valued at zero. The contingent consideration payment ranges from zero to $13.1 million based on reaching revenue and adjusted EBITDA performance targets in 2014 and 2015. For 2014, the performance targets were not reached.
	The purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values. We allocated $0.3 million to customer relationships, $0.6 million to developed technology and $0.4 million to noncompetition agreements. The customer relationships, developed technology and noncompetition agreements acquired in the transaction are being amortized on a straight-line basis over 5 years, 4 years and 4 years, respectively. The weighted average amortization period is 4.2 years. The intangible assets created in the acquisition are deductible for income tax purposes. For the period from the acquisition date through December 31, 2013, we recognized $0.1 million of revenue and a $0.3 million loss before income taxes from Republic Project in our results of operations. The Republic Project purchase price allocation is final.
	Purchase of Peer39
	On April 30, 2012, we acquired Peer39, Inc. ("Peer39"), a provider of webpage level data for approximately $15.7 million in cash, shares of DG's common stock and an installment payment. Peer39 is the leading provider of data based on the content and structure of web pages for the purpose of improving the relevance and effectiveness of online display advertising. Peer39 analyzes web pages in terms of quality, safety and brand category which allows advertisers to make better buying decisions.
	In connection with the transaction, (i) we paid $10.1 million in cash, (ii) DG issued 357,143 shares of its common stock and (iii) we agreed to pay up to $2.3 million in an installment payment within one year of the acquisition. The installment payment represented amounts we withheld to address any unrecorded liabilities or other unreported claims that may have existed on the purchase date.
	The purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values. In 2012, we finalized the Peer39 purchase price allocation. The customer relationships, trade name, developed technology and noncompetition agreements acquired in the transaction are being amortized on a straight-line basis over 10 years, 10 years, 6 years and 4 years, respectively. The weighted average amortization period is 7.1 years. The goodwill and intangible assets created in the acquisition are not deductible for income tax purposes. The acquired assets include $0.8 million of gross receivables which we recognized at their estimated fair value of $0.8 million. For the eight months ended December 31, 2012, we recognized $4.4 million of revenue and a $1.4 million loss before income taxes from Peer39 in our results of operations.
	Transfer Majority of Chors
	In September 2011, we acquired EyeWonder LLC ("EyeWonder") and chors GmbH (a German limited liability company "Chors"). On April 2, 2012, in consideration of $0.1 million, we transferred the majority of the assets, agreements and employees of Chors to 24/7 Real Media Deutschland GmbH ("24/7 Germany"), a German limited liability company, and an affiliate of WPP plc, an international advertising and media investment management firm. For the three months ended March 31, 2012, we reported $1.3 million of revenue and $0.3 million of income before income taxes from Chors. We did not report a significant gain or loss in connection with the transfer.

	Goodwill
	We operate as a single reporting unit. Changes in the carrying value of our goodwill for the years ended December 31, 2014 and 2013 are as follows (in thousands):

			Goodwill			Accumulated			Net
						Impairment			Carrying
						Losses			Value
	Balance at December 31, 2012		$	376,417		$	(242,331	)	$	134,086

	Balance at December 31, 2014		$	380,681		$	(340,527	)	$	40,154


	We evaluate goodwill for possible impairment each year on December 31st and whenever events or changes in circumstances indicate the carrying value of our goodwill may not be recoverable. Generally, the goodwill impairment test involves a two-step process. In the first step, we compare the fair value of the Company to its carrying value. If the fair value of the Company exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of the Company is less than its carrying value, we must perform the second step of the impairment test to measure the amount of the impairment loss. In the second step, the Company's fair value is allocated to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the Company was being acquired in a business combination. If the implied fair value of the Company's goodwill is less than the carrying value, the difference is recorded as an impairment loss.
	ASC 350-20-35 allows an entity to assess qualitatively whether it is necessary to perform step one of the prescribed two-step annual goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, the two-step goodwill impairment test is not required. At December 31, 2014, we performed a qualitative assessment of our goodwill and determined that the two-step process was not necessary. We considered that as of September 30, 2014 we had adjusted our goodwill to its fair value (see below), and since then (i) our operating results were in line with our September 2014 forecast, (ii) our December 2014 forecast reflects a slightly improved outlook and (iii) our market capitalization (an indicator of the fair value of the Company) has improved from the level used in our third quarter impairment analysis.
	2014 Goodwill Impairment Loss
	At December 31, 2013, based on a variety of methods including a discounted cash flow model (a Level 3 fair value measurement) that used our internal forecast, we determined the fair value of the Company was only 5% in excess of its carrying value. In preparing our discounted cash flow model, we made assumptions about future revenues and expenses to determine the cash flows that would result from our operations.
	We noted at the time, and at each of the next two quarters, there was substantial risk our forecasted cash flows may fall short of our expectations. We noted that if actual or expected future cash flows should fall sufficiently below our forecast, it would likely require us to record another goodwill impairment charge (in addition to the impairment charge taken in 2012). We noted future net cash flows are impacted by a variety of factors including revenues, operating margins, capital expenditures, income tax rates, and a discount rate.
	We also noted the market value of our common stock plus a reasonable control premium is an indicator of the fair value of our Company. We noted that if the market value of our common stock should decline sufficiently below its initial trading value (initial trading began in February 2014) for an extended period of time, it would likely cause us to conclude that our goodwill was impaired and we would be required to record another goodwill impairment charge. At each of March 31, 2014 and June 30, 2014, we continued to monitor our goodwill and determined an interim goodwill impairment test was not required.
	During the third quarter of 2014, we determined that indicators of potential impairment existed requiring us to perform an interim goodwill impairment test. These indicators included (i) revenues and operating results sufficiently below our earlier forecast which prompted us to revise our future forecast, (ii) our market capitalization continuing to decline throughout 2014 such that our market capitalization plus a reasonable control premium was well below the book value of our total stockholders' equity, (iii) a decreasing trend in our revenue growth, and (iv) turnover within the sales executive team.
	In performing our interim goodwill impairment test, we estimated the fair value of the Company using an income approach, specifically a discounted cash flow model (a Level 3 fair value measurement). Under the income approach, we calculated the fair value of the Company based on the present value of its estimated future cash flows. Cash flow projections are based on a variety of estimates including revenue growth rates, operating margins, tax rates, capital expenditures and a discount rate. The discount rate used was based on our weighted average cost of capital adjusted for the risks associated with the Company's projected cash flows.
	Upon estimating the fair value of our goodwill, we determined it was less than its carrying value. As a result, we performed the second step of the impairment analysis and allocated the fair value of the Company to each of its assets and liabilities (including identifiable intangible assets) with the excess fair value being the implied goodwill. Estimating the fair value of certain assets and liabilities requires significant judgment about future cash flows. The implied fair value of the Company's goodwill was $98.2 million less than its carrying value, which we recorded as a goodwill impairment loss during the third quarter of 2014.
	To verify the reasonableness of the fair value of the Company, we compared the Company's adjusted carrying value to its market capitalization plus a reasonable control premium. We determined the implied control premium of about 42% was reasonable based upon a review of historical control premiums of comparable companies. In accordance with our policy, at December 31, 2014 we performed our annual goodwill impairment test and determined no additional impairment was required.
	Risk of Future Impairment
	At December 31, 2014, based on our discounted cash flow model that uses our internal forecast, we determined the fair value of the Company was only slightly in excess of its carrying value. In preparing our discounted cash flow model, we made assumptions about future revenues and expenses for several periods to determine the cash flows that will result.
	As with any forecast, there is substantial risk our forecasted cash flows may fall short of our current expectations. If actual or expected future cash flows should fall sufficiently below our current forecast, it is likely we would be required to record another goodwill impairment charge. Future net cash flows are impacted by a variety of factors including revenues, operating margins, capital expenditures, income tax rates, and a discount rate.
	Further, the market value of our common stock plus a reasonable control premium is an indicator of the fair value of our Company. If the market value of our common stock should fall sufficiently below the current level for an extended period of time, it would likely cause us to conclude that our goodwill is impaired and we would be required to record another goodwill impairment charge.

Intangible assets are initially stated at their estimated fair value at the date of acquisition. Subsequently, intangible assets are adjusted for amortization expense and any impairment losses recognized. Net intangible assets decreased during the year ended December 31, 2014 as a result of amortization expense, partially offset by our acquisition of Aerify Media (see Note 3). Amortization expense related to intangible assets totaled $15.6 million, $15.8 million and $15.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Fair Value Measurements

7. Fair Value Measurements

ASC 820, Fair Value Measurements, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.

ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

•

Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

Financial Assets and Liabilities Measured on a Recurring Basis

We have classified our assets and liabilities that are measured at fair value on a recurring basis (at least annually) into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date.

The tables below set forth by level assets and liabilities that were accounted for at fair value as of December 31, 2014 and 2013. The carrying values of our accounts receivable and accounts payable approximate their respective fair values due to the short-term nature of these financial instruments. The tables do not include cash on hand or assets and liabilities that are measured at historical cost or any basis other than fair value (in thousands).

The fair value of our money market funds was determined based upon quoted market prices. The currency forward derivatives/options are derivative instruments whose value is based upon quoted market prices from various market participants. We have a zero cost basis in these derivative instruments. Our marketable equity securities relate to a single issuer that has a cost basis of $0.3 million.

In connection with our Spin-Off from DG, DG contributed a revenue sharing asset to us that resulted from DG's sale of its Springbox unit. We are entitled to a percentage of the revenues collected by the business for three years after the closing date (June 1, 2012). Revenue sharing payments are generally made once a year. We have estimated the future revenues of Springbox based on the historical revenues and certain other factors, discounted to their present value. The following table provides a reconciliation of changes in the fair values of our Level 3 assets (in thousands):

Also, in connection with our Spin-Off from DG, we assumed a portion of a revenue earnout arrangement that DG had agreed to in its purchase of North Country. Further, in connection with an acquisition of a business, we sometimes include a contingent consideration component of the purchase price based on (i) future revenues or (ii) future revenues and operating results (e.g., adjusted EBITDA), that require minimum thresholds be met before any earnout payment becomes due. Accordingly, there can be significant volatility in the earnout liability. Each reporting period, we review our estimates of the performance indicators (e.g., revenue, adjusted EBITDA) and the corresponding earnout levels achieved, discounted to their present values. The change in fair value is recorded in cost of revenues in the accompanying statements of operations.

In connection with our acquisition of Republic Project, we agreed to make additional payments to the sellers if Republic's 2014 or 2015 revenues and adjusted EBITDA exceed certain levels. As of December 31, 2014, we do not expect to make any payments with respect to the Republic Project contingent consideration arrangement. See Note 3—Purchase of Republic Project.

Abakus Convertible Notes

In May 2014, we purchased $1.0 million of Abakus convertible promissory notes ("Convertible Notes") for $1.0 million. The Convertible Notes are due 90 days after written notice after the earlier of (i) May 30, 2016 or (ii) an occurrence of an Event of Default (as defined in the Convertible Notes). Abakus is a small private company that has developed a digital attribution software solution. The Convertible Notes bear interest at 5% per annum payable at maturity. The Convertible Notes are convertible into Abakus Series A Preferred Stock ("Series A Preferred") as follows:

Automatic conversion if Abakus sells $2.0 million of Series A Preferred ("Qualified Financing"), whereupon the Convertible Notes shall be converted, at Sizmek's option, at either (i) 75% of the share price in the Qualified Financing, or (ii) the quotient of $7.0 million divided by the number of shares outstanding upon exercise of all dilutive securities, and

Optional conversion at Sizmek's election if Abakus completes an Equity Financing (as defined in the Convertible Notes) that is not a Qualified Financing, whereupon the Convertible Notes shall be converted at 75% of the share price in the Equity Financing.

In addition, upon a Change in Control, as defined in the Convertible Notes, the Convertible Notes shall be paid off at the greater of (i) the outstanding balance, or (ii) the amount the holder would have received upon conversion of the Convertible Notes. The Convertible Notes are considered held-to-maturity securities and are carried at amortized cost. The fair value of the Convertible Notes is not readily determinable. We are not aware of a market for the Convertible Notes. The Convertible Notes are included in other non-current assets.

Financial Assets and Liabilities Measured on a Nonrecurring Basis

Except for the impairments of our goodwill during 2014 and 2012, we did not record any material other-than-temporary impairments on financial assets required to be measured at fair value on a nonrecurring basis. See Note 5.

For periods subsequent to our Spin-Off, we file separate tax returns on a stand-alone basis.
For periods prior to our Spin-Off, we calculated the benefit for income taxes as if we were a stand-alone entity and filed separate tax returns. For periods prior to the Spin-Off, if we had filed separate tax returns we would have generated U.S. federal and state NOLs. Those hypothetical NOLs and the corresponding tax benefits were fully utilized by DG, our former parent, in the same period. For the losses incurred in the financial statement periods, we evaluated whether or not such losses could be realized if we did not have the benefit of filing a consolidated income tax return with DG. For the period of January 1 to February 7, 2014 we determined under ASC 740 that generated losses were not realizable and therefore the tax benefits for the losses generated and contributed to DG were not provided. These unbenefited losses did not result in additional valuation allowance on the balance sheet, as they were contributed through net parent funding/equity. Any U.S. tax benefit utilized by the parent is reclassified to net parent funding in the same period. Any valuation allowance and corresponding tax expense relate to separate company deferred tax assets, mainly acquired NOLs that will be carried forward into 2015.
For periods prior to our Spin-Off, any tax attributes utilized by the parent were reclassified to business capital in the same period. As of December 31, 2014, we had NOL carryforwards with a tax-effected carrying value of approximately $4.4 million for federal purposes. Our federal NOLs will expire in 2030. Utilization of these carryforwards will be limited on an annual basis as a result of previous business combinations pursuant to Section 382 of the Internal Revenue Code. Expected future limitations are as follows (in millions, amounts shown are not tax effected):

Years		Annual
Years		Limitation
2015		$	1.4
2016		$	0.8
2017 - 2030 (per year)		$	0.5
We provide a valuation allowance for deferred tax assets when we do not have sufficient positive evidence to conclude that it is more likely than not that some portion, or all, of our deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon future taxable income during the periods in which those temporary differences become deductible. In assessing the need for a valuation allowance for our deferred tax assets, we considered all available positive and negative evidence, including our ability to carry back operating losses to prior periods, the reversal of deferred tax liabilities, tax planning strategies and projected future taxable income. Given our history of losses, we do not believe we have sufficient positive evidence to conclude that future realization of all of our federal net deferred tax assets is more likely than not. As such, we have maintained a valuation allowance on deferred tax assets to the extent they exceed our deferred tax liabilities in the same jurisdiction. We will continue to reassess the valuation allowance quarterly, and if future events or sufficient evidence exists to suggest such amounts are more likely than not to be realized, a tax benefit will be recorded to adjust the valuation allowance.
We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Interest and penalties related to uncertain tax positions are recognized in income tax expense. For the year ended December 31, 2014, we recognized $0.7 million of interest or penalties related to uncertain tax positions in our consolidated financial statements. For the year ended December 31, 2013, we recognized $0.2 million of interest or penalties related to uncertain tax positions in our combined financial statements. For the year ended December 31, 2012, we did not recognize any interest or penalties related to uncertain tax positions in our combined financial statements. At December 31, 2014 and 2013, $0.7 million and $0.2 million of interest and penalties were included in our balance sheets, respectively.
The change in unrecognized tax benefits for the years ended December 31, 2014, 2013, and 2012, was as follows (in thousands):

		Years Ended December 31,
		2014			2013			2012

Balance at end of year		$	1,507		$	1,701		$	1,801


If we reduced our reserve for uncertain tax positions, it would result in us recognizing a tax benefit. Upon the taxing authority accepting those tax returns, we expect substantially all of the uncertain tax positions to be effectively settled within 12 months.
As of December 31, 2014, we provided a valuation allowance against substantially all of our U.S. and state NOL carryforwards as ultimate realization of these NOLs was not determined to be more likely than not. Accordingly, we have NOL carryforwards available to us (should we have sufficient future taxable income to utilize them) that are not reflected in our consolidated and combined balance sheets at December 31, 2014 and 2013, respectively.
We are subject to U.S. federal income tax, income tax from multiple foreign jurisdictions including Israel and the United Kingdom, and income taxes of multiple state jurisdictions. U.S. federal, state and local income tax returns for 2011 through February 7, 2014 remain open to examination. Israeli and United Kingdom income tax returns remain open to examination for 2008 through 2014 and 2009 through 2014, respectively. Prior to our Spin-Off, our operating results had been included in DG's U.S. federal and state tax returns or tax returns of non-U.S. jurisdictions. Subsequent to our Spin-Off, we will file stand-alone income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and various foreign jurisdictions. Prior to our Spin-Off, we entered into a tax matters agreement with DG that governs the parties' respective rights, responsibilities and obligations with respect to taxes. The tax matters agreement generally provides that the filing of tax returns, the control of audit proceedings, and the payment of any additional tax liability relative to periods prior to February 8, 2014 is our responsibility.
We do not provide deferred taxes on the undistributed earnings of our non-U.S. subsidiaries in situations where our intention is to reinvest such earnings indefinitely. Furthermore, all of our U.S. and non-U.S. subsidiaries have significant net assets, liquidity, and other financial resources available to meet their operational and capital investment requirements. As of December 31, 2014, we recorded a deferred tax liability for undistributed earnings, including applicable withholding taxes, in the amount of $0.3 million that are expected to be remitted in the foreseeable future. This deferred tax liability is a result of dissolving, merging, or liquidating purchased legal entities according to management's stated plan of integration. As of December 31, 2014, the aggregate undistributed earnings of our non-U.S. subsidiaries subject to indefinite reinvestment totaled $6.8 million. Should we make a distribution in the form of dividends or otherwise, we may be subject to additional income taxes. The unrecognized deferred tax liability related to the undistributed earnings of our non-U.S. subsidiaries is estimated to be $2.5 million as of December 31, 2014. This assumes we will not be able to recognize the benefits of a foreign tax credit upon remittance of the foreign earnings due to expected losses in the United States.

We match 25% of the amount contributed by employees, up to a maximum employee contribution of 6% of gross earnings. Prior to the Spin-Off, our U.S. based employees participated in DG's 401(k) retirement plan. During 2014, 2013 and 2012, we made matching contributions on behalf of our employees of approximately $303,000, $252,000 and $261,000, respectively.

	Since the Spin-Off on February 7, 2014, all share-based compensation expense relates to the Sizmek 2014 Incentive Award Plan (the "2014 Plan"). All share-based compensation recognized prior to the Spin-Off relates to DG's equity-based incentive programs. Prior to the Spin-Off, certain of our employees participated in DG's equity incentive programs. Immediately prior to completing the Spin-Off, all of DG's outstanding equity awards became fully vested and, to the extent the award had an intrinsic value, were converted into shares of DG common stock. Equity awards with no intrinsic value were cancelled. DG's equity incentive plans were terminated in connection with the Merger Agreement (see Note 1). Below is a summary of our share-based compensation expense (in thousands):

	Shares in the Plan, Terms and Vesting
	Under the 2014 Plan, the compensation committee of our Board of Directors (the "Committee") is authorized to grant awards to our employees, non-employee directors and consultants. Awards can take the form of (i) stock options, (ii) restricted stock, (iii) restricted stock units ("RSUs"), (iv) performance awards, (v) dividend equivalents, (vi) stock payments and (vii) stock appreciation rights. The 2014 Plan provides that the maximum number of shares of common stock with respect to which awards may be granted shall not exceed 4,500,000, plus
	(i)	any shares tendered or withheld to satisfy the exercise price of an option or any tax withholding obligation pursuant to any award under the 2014 Plan,
	(ii)	any shares subject to a stock appreciation right that are not issued in connection with the stock settlement of the stock appreciation right on its exercise, and
	(iii)	any shares purchased on the open market with the cash proceeds from the exercise of options.
	In addition, to the extent all or a portion of an award is forfeited, expires or is settled for cash, the shares subject to the award shall, to the extent of such forfeiture, expiration or cash settlement, again be available for future grants. Further, any shares of restricted stock repurchased by us or surrendered to us shall again be available for future grant. Further, awards granted under the 2014 Plan upon the assumption of, or in substitution for, outstanding equity awards of an entity we acquire (substitute awards), will not reduce the shares authorized for grant under the 2014 Plan. Further, in the event that a company acquired by us has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant may be used for awards under the 2014 Plan and will not reduce the shares authorized for grant under the 2014 Plan, but such awards will only be made to individuals who were not employed by or providing services to us immediately prior to such acquisition or combination.
	Generally, the granting of share-based awards including the terms and vesting schedules thereof is authorized by the Committee. The exercise price of stock options shall not be less than the fair value of our common stock on the date of grant. Stock option grants typically have terms of ten years, vest over three years, and are recognized on a straight-line basis over the vesting term. At December 31, 2014, there were a total of 3,389,471 shares of common stock available for future grant under the 2014 Plan.
	Stock Options
	A summary of 2014 stock option activity pursuant to the 2014 Plan is presented below:

			2014

				542,846			9.25	$	9.66		7,713	$	12.39


	Options granted in 2014 had a weighted average grant-date fair value of $5.65 per share. The weighted average remaining contractual life of vested stock options at December 31, 2014 was 0.2 years. At December 31, 2014, the intrinsic value of options outstanding and options exercisable was less than $0.1 million and $0.0 million, respectively. The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the option exercise price.
	Unrecognized compensation costs related to our stock options was $2.2 million at December 31, 2014. These costs are expected to be recognized over the weighted average remaining vesting period of 2.0 years. The fair value of each option was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

			2014
	Number of options granted			620,841
	Weighted average exercise price of options granted		$	9.74
	Volatility(1)			62.7	%
	Risk free interest rate(2)			1.94	%
	Expected term (years)(3)			5.94
	Expected annual dividends			None


-1	Since our common stock has a limited trading history (trading began in February 2014), we based our expected volatility on the historical volatility of DG's common stock over a preceding period commensurate with the expected term of the option.
-2	The risk free rate is based on the U.S. Treasury yield curve at the time of grant for periods consistent with the expected term of the option.
-3	The expected term was calculated as the average between the vesting term and the contractual term, weighted by tranche. We used the simplified method discussed in ASC 718-10-S99-1 as we do not have sufficient historical data in order to calculate a more appropriate estimate.
RSUs—Time Based
In 2014, subsequent to the Spin-Off, the Committee awarded 410,332 time-based RSUs to our employees and non employee directors. The total grant date fair value of the time-based RSUs was $4.2 million. As of December 31, 2014, the total fair value of outstanding time-based RSUs that have vested or we expect to vest was $2.4 million. The awards (i) vest over periods ranging from nine months to three years and (ii) are subject to the awardees' continued employment with us or continuing to provide services to us.
In 2014, we recognized $1.4 million in share-based compensation expense related to time-based RSUs. At December 31, 2014, the unrecognized compensation costs related to time-based RSUs was $2.5 million. The amount of share-based compensation expense we ultimately recognize will depend on the degree to which the time-based service conditions are satisfied. The grant date fair value of the time-based RSUs that vested during 2014 was less than $0.1 million. At December 31, 2014, the nonvested time-based RSUs had a weighted average remaining vesting period of 1.8 years and an intrinsic value of $2.4 million.
A summary of our time-based RSU activity for 2014 is presented below:

		2014
		Shares			Weighted Average
					Grant-Date
					Fair Value
					per Share
Nonvested shares at beginning of year			—		$	—
Granted			410,332			10.15
Vested			(4,910	)		12.39
Forfeited			(25,345	)		11.14

Nonvested shares at end of year			380,077		$	10.06


RSUs—Performance Based
In 2014, subsequent to the Spin-Off, the Committee awarded 204,280 performance-based RSUs to certain of our employees. The total grant date fair value of the performance-based RSUs was $2.2 million. As of December 31, 2014, the total fair value of outstanding performance-based RSUs that have vested or we expect to vest was $1.2 million.
The awards (i) vest over periods ranging from seven months to 34 months, (ii) are subject to the awardees' continued employment with us and (iii) are subject to reaching certain (a) revenue, (b) adjusted EBITDA and (c) free cash flow growth targets (i.e., performance conditions). The amount of share-based compensation expense we ultimately recognize will depend on the degree to which the performance conditions are satisfied. As a result, there can be significant volatility in the amount of share-based compensation expense we recognize from period to period due to differences between actual and expected results, and changes in our estimates of future results.
In 2014, we recognized $0.7 million in share-based compensation expense related to performance-based RSUs. At December 31, 2014, the unrecognized compensation costs related to performance-based RSUs was $0.2 million. The unrecognized compensation costs is based on our current estimate of future operating results and could change significantly in the future. At December 31, 2014, the nonvested performance-based RSUs had a weighted average remaining vesting period of 1.2 years and an intrinsic value of $1.2 million.
According to the terms of the performance-based RSU agreements, after the performance period has ended, the RSUs do not vest until the performance results are certified by the Committee. The first performance period ended on December 31, 2014 and, once the performance results are certified, we expect to issue 52,407 shares of common stock with a weighted average grant-date fair value $10.79 per share.
A summary of our performance-based RSU activity for 2014 is presented below:

		2014
		Shares			Weighted Average
					Grant-Date
					Fair Value

Nonvested shares at beginning of year			—		$	—
Granted			204,280			10.59

Nonvested shares at end of year			196,199		$	10.64


Pre Spin-Off—Participation in DG's Stock Plans
Prior to the Spin-Off, certain of our employees participated in DG's equity-based incentive programs. DG allocated the cost of our employees' participation in those plans to us. Prior to the Spin-Off, we did not have any equity-based incentive plans ourselves. In addition, DG allocated a portion of the cost of share-based awards for their corporate services personnel to us. As discussed above, in connection with the Spin-Off all DG equity-based incentive awards became fully vested and, to the extent they had intrinsic value, were converted into shares of DG common stock. Immediately prior to the Spin-Off, equity awards with no intrinsic value were cancelled and DG's equity incentive plans were terminated. Below is a summary of DG's equity-based incentive awards in which our employees participated:
DG Stock Options
In 2012, certain of our employees were awarded DG stock options to purchase 120,000 shares of DG's common stock. The weighted-average exercise price for the 2012 grants was $9.20. The stock options had a four year vesting period and a ten year contractual life. The fair value of the DG stock options granted was determined using the Black-Scholes option pricing model. The various inputs used to determine the fair value were specific to DG, and were not necessarily representative of the inputs we may have used.
DG RSUs
In 2013 and 2012, certain of our employees were awarded DG RSUs. The RSUs were granted to our employees at no cost and restrictions on transfer lapsed over a three year period. The fair value of each award was equal to the fair value of DG's common stock on the date of grant. For 2013 and 2012, the fair value of the DG RSUs granted to our employees was $1.0 million and $1.2 million, respectively, and the weighted-average fair value per share was $6.20 and $10.04, respectively.
Allocating Share-based Compensation of DG's Corporate Services Personnel
A portion of the cost of DG's corporate-related services, which includes executive management and administrative personnel, has been allocated to us in these financial statements. In addition, DG has allocated to us a portion of the cost of its share-based compensation programs for these corporate-related services personnel. For 2014, 2013 and 2012, DG allocated $3.8 million, $3.0 million and $1.8 million, respectively, to us for share-based compensation of its corporate services personnel.
Stock Repurchase Program
In August 2014, our Board of Directors approved a $15 million share repurchase program. In March 2015, our Board of Directors increased the share repurchase program to $30 million. The program allows us to repurchase shares of our common stock through open market purchases, privately negotiated transactions or otherwise, subject to certain conditions. The share repurchase program does not have an expiration date. Through December 31, 2014, we made share repurchases totaling $2.0 million. Depending on market conditions and other factors, these repurchases may be commenced or suspended from time to time without notice. We have no obligation to repurchase shares under the share repurchase program.

	Prior to the Spin-Off, DG provided certain management and administrative services to us. These services included, among others, accounting, treasury, audit, tax, legal, executive oversight, human resources, real estate, information technology and risk management. These expenses have been allocated to us on a basis of direct usage when identifiable, with the remainder allocated on the basis of revenue, headcount, or other measures. Further, DG also allocated to us (i) merger, integration and other expenses and (ii) share-based compensation, largely based on revenues. DG's allocation of these expenses to us was as follows (in thousands):

	DG's Expense Allocation to Sizmek		2014			2013			2012
	Management and administrative services		$	637		$	9,056		$	8,837
	Merger, integration and other			4,038			4,297			1,127
	Share-based compensation			3,817			3,012			1,778

	Total		$	8,492		$	16,365		$	11,742


	Included in the above allocations are costs of DG's employee benefit plans and other employee incentives. Employee benefits and incentives include 401(k) matching contributions, participation in DG's long-term incentive compensation award plans and healthcare plans. The employee benefit and incentive costs are reflected in the statements of operations and are classified consistently with how the underlying employee's salary and other compensation costs have been recorded.
	We consider the allocated cost for corporate services, employee benefits and incentives to be reasonable based on our utilization of such services. However, we believe the allocated cost for the services are different from the cost we would have incurred if we had been an independent publicly-traded company during those periods.
	In addition, DG primarily used a centralized approach to cash management and the financing of its operations with all related activity between DG and us reflected in stockholders' equity or business capital in the accompanying balance sheets. The transactions included:
	•	our cash deposits that were transferred to DG's bank accounts on a regular basis;
	•	cash infusions from DG to fund our operations, capital expenditures and acquisitions;
	•	allocations of DG's corporate services, employee benefits and other incentives; and
	•	intercompany charges for expenses related to facilities we shared with DG's other business segment.
	The following is a reconciliation of the amounts presented as "Net contributions from Parent" on the statement of stockholders' equity or business capital and the amounts presented as "Net contributions from Parent" and monetization of other Parent contributions on the statements of cash flows (in thousands):

	Pursuant to the Merger Agreement, shortly prior to the Spin-Off, DG contributed to us all of its cash, and most of its other current assets and liabilities relating to its TV business. The vast majority of the assets have since been monetized and the liabilities have been paid. The remaining identifiable TV assets and liabilities are summarized in Note 2.

	Litigation
	Although the Company is not a party to any of the litigation discussed below, under the Separation and Redemption Agreement that we entered into with DG in connection with the Spin-Off, we have agreed to indemnify and hold harmless DG and its former directors for the costs of defending the cases, and any damages that may be awarded to the plaintiff and purported class of former DG stockholders.
	On January 14, 2014, a purported holder of common stock of Digital Generation, Inc. ("DG"), Equity Trading ("Plaintiff"), filed a complaint in the Supreme Court of the State of New York, County of New York, Equity Trading v. Scott K. Ginsburg, et al., No. 050112/2014, on behalf of itself and all others similarly situated, against DG, all directors of DG, Extreme Reach, Inc. ("Extreme Reach") and Dawn Blackhawk Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of Extreme Reach ("Acquisition Sub"), alleging breaches of fiduciary duty in connection with the then pending Agreement and Plan of Merger, dated as of August 12, 2013, by and among Extreme Reach, Acquisition Sub and DG. The complaint sought an injunction barring the consummation of the transaction and unspecified monetary damages.
	On January 16, 2014, Plaintiff filed with the New York state court a request seeking an order (i) preliminarily enjoining the Merger, (ii) requiring expedited discovery and (iii) scheduling a post-discovery hearing to continue the injunction (Plaintiff's "Request"), and on January 17, 2014, the New York state court issued an order setting a briefing schedule and a hearing for January 30, 2014, on Plaintiff's Request. On January 27, 2014, the defendants removed this action from the New York state court to the United States District Court for the Southern District of New York, causing the matter to now be captioned Equity Trading v. Scott K. Ginsburg, et al., 14 Civ. 499 (RWS) (RLE). The defendants also submitted briefing in opposition to the Request. At a hearing held on January 30, 2014, the Court denied Plaintiff's Request. On February 4, 2014, the Court agreed to a Stipulation for Extension of Time and Order (the "Scheduling Order"), providing a proposed briefing schedule. On February 26, 2014, Plaintiff filed a Motion to Remand the action to the Supreme Court of the State of New York, County of New York. On March 12, 2014, the defendants stipulated to remand. On April 11, 2014, Plaintiff filed an amended complaint, asserting the same causes of action as the initial complaint and adding certain additional factual allegations. On July 18, 2014, the defendants filed motions to dismiss the amended complaint. On September 16, 2014, Plaintiff filed oppositions to the motions to dismiss and a cross-motion to strike exhibits to the motions to dismiss. On October 24, 2014, the defendants filed replies in support of the motions to dismiss and an opposition to the cross-motion to strike. On November 14, 2014, Plaintiff filed a reply in support of the cross-motion to strike. Oral argument on the motions to dismiss and cross-motion to strike took place on February 5, 2015.
	On March 13, 2015, Plaintiff and the defendants entered into a stipulation providing for the above-described action to be discontinued in its entirety without prejudice, with all of the parties bearing their own costs. The stipulation was filed with the Supreme Court of the State of New York, County of New York on March 15, 2015, and the court thereafter dismissed the action.
	Leases
	We lease office and storage facilities under non-cancelable operating leases. Generally, these leases are for periods of three to ten years and usually contain one or more renewal options. Our two most significant leases are in New York City, NY and Herzliya, Israel. The New York lease is for ten years and expires in 2024. The Herzliya lease is for ten years and expires in 2021. The table below summarizes our lease obligations for office and storage facilities, including amounts for escalating operating lease rental payments, at December 31, 2014 (in thousands):

	Basic earnings (loss) per common share excludes dilution and is calculated by dividing net earnings (loss) by the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per common share is calculated by dividing net earnings (loss) by the weighted-average number of common shares outstanding during the period, as adjusted for the potential dilutive effect of non-participating share-based awards such as stock options and RSUs.
	On February 7, 2014, 30.4 million shares of our common stock were distributed to DG stockholders in conjunction with the Spin-Off. For comparative purposes, and to provide a more meaningful calculation of the weighted-average shares outstanding, we have assumed this amount to be outstanding throughout each period presented prior to the Spin-Off in the calculation of weighted-average shares outstanding.

Summary of Significant Accounting Policies
Basis of Presentation
	Basis of Presentation
	The consolidated and combined financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and include the accounts of our wholly-owned, and majority-owned and controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. For the periods prior to the Spin-Off, the carve-out financial statements have been prepared on a basis that management believes to be reasonable to reflect the financial position, results of operations and cash flows of the Company's operations, including portions of DG's corporate costs and administrative shared services.

Revenue Recognition
	Revenue Recognition
	We derive revenue primarily from volume-based fees for using our online ad serving platform. We recognize revenue only when all of the following criteria have been met:
	•	Persuasive evidence of an arrangement exists,
	•	Delivery has occurred or services have been rendered,
	•	Our price to the customer is fixed or determinable, and
	•	Collectability is reasonably assured.
	We offer online advertising campaign management and deployment products. These products allow publishers, advertisers, and their agencies to manage the process of deploying online advertising campaigns. We charge our customers on a cost per thousand ("CPM") impressions basis, and recognize revenue when the impressions are served. In some instances, we charge a flat fee for a campaign and recognize revenue ratably over the period of the campaign.
	We also offer programmatic managed services. In providing these services, we enter into arrangements with third parties to facilitate our customer's online advertising. The determination of whether we should recognize revenue on a gross or net basis is based on an assessment of whether we are acting as the principal, or an agent, in the transaction. In determining whether we are acting as the principal or an agent, we follow the accounting guidance for principal-agent considerations. While none of the factors identified in this guidance is individually considered presumptive or determinative, because we are the primary obligor in the arrangement and we are responsible for (i) selecting and contracting with third party suppliers for the purchase of inventory, (ii) managing the advertising process including selecting or advising on campaign parameters, monitoring campaign results, and adjusting parameters and modifying publishers throughout the campaign to optimize results, (iii) establishing the selling price, and (iv) assuming credit risk in the transaction, we act as the principal in these arrangements and therefore we report revenues earned and costs incurred on a gross basis.
	For 2014, 2013 and 2012, we reported revenues and cost of revenues from programmatic managed services as follows (dollars in thousands):

			Years Ended December 31,
			2014			2013			2012
	Revenues		$	16,737		$	10,530		$	4,695
	% of total revenues			9.8	%		6.5	%		3.3	%
	Cost of revenues(1)			11,818			7,915			3,924

	Net		$	4,919		$	2,615		$	771




	-1	Includes the cost of purchasing media, but does not include personnel and other overhead related costs that are recorded in cost of revenues.


Seasonality
	Seasonality
	Our business is seasonal. Revenues tend to be the highest in the fourth quarter as a large portion of our revenues follow the advertising patterns of our customers.

Use of Estimates
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the recoverability and useful lives of long-lived assets, the adequacy of our allowance for doubtful accounts and credit memo reserves, contingent consideration and income taxes. We base our estimates on historical experience, future expectations and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
	In 2014 and 2012, we recorded goodwill impairment charges of $98.2 million and $219.6 million, respectively. See Note 5 for a discussion of the risk of a future impairment of our goodwill.
	Effective November 1, 2014, we shortened the estimated remaining useful life of our Sizmek MDX platform assets from an average of 46 months to 20 months in anticipation of our new platform (which is currently in development). We anticipate the new platform will be operational by the end of 2015 and we expect to retire our existing platform by mid-2016. As a result, we recorded additional depreciation expense of $0.6 million during 2014, which increased our net loss and loss per share by $0.5 million and $0.02, respectively.

Cash and Cash Equivalents
	Cash and Cash Equivalents
	Cash equivalents consist of liquid investments with original maturities of three months or less at the date of acquisition. We maintain substantially all of our cash and cash equivalents with a few major financial institutions in the United States and Israel.

Restricted Cash
	Restricted Cash
	Restricted cash principally relates to (i) funding of Israeli statutory employee compensation, (ii) required cash balances for foreign currency forward contracts and options, and (iii) security deposits on office leases.

Accounts Receivable and Allowances
	Accounts Receivable and Allowances
	Accounts receivable are recorded at the amount invoiced, provided the revenue recognition criteria have been met, less allowances for doubtful accounts and credit memos. We maintain allowances for doubtful accounts and credit memos on an aggregate basis, at a level we consider sufficient to cover estimated losses in the collection of our accounts receivable and credit memos expected to be issued. The allowance is based primarily on known troubled accounts, the collectability of specific customer accounts and customer concentrations, with consideration given to current economic conditions and trends. We charge off accounts that remain uncollected after reasonable collection efforts are made.

Property and Equipment, Net
	Property and Equipment, Net
	Property and equipment are stated at cost. Depreciation is computed over the estimated useful lives of the assets using the straight-line method. Leasehold improvements are amortized on a straight-line basis over the shorter of the remaining lease term plus expected renewals or the estimated useful life of the asset. The estimated useful lives of our property and equipment (excluding property and equipment acquired in a business combination) are principally as follows:

	Category		Useful Life
	Software—internally developed software costs		2 - 5 years
	Software—purchased		3 years
	Computer equipment		3 years
	Furniture and fixtures		6 - 14 years
	Network equipment		3 years
	Machinery and equipment		3 years


Long-Term Investments
	Long-Term Investments
	We acquired available for sale equity securities with an original cost of $1.2 million. During 2012, these securities declined in value to about $0.3 million. We determined the decline in value was other than temporary and, as a result, recorded an impairment charge of $0.9 million (cost basis of $1.2 million less fair value of $0.3 million). Also during 2012, we made a $1.5 million equity investment in a company that was developing a web-based audience and content measurement platform. Later in 2012, we determined that our investment was impaired and wrote-off the investment. These two charges are recorded in "other (income) and expense, net" in the accompanying statements of operations.

Leases
	Leases
	We lease certain properties under operating leases, generally for periods of 3 to 10 years. Some of our leases contain renewal options and escalating rent provisions. For leases that provide for escalating rent payments or free-rent occupancy periods, we recognize rent expense on a straight-line basis over the non-cancelable lease term plus option renewal periods where failure to exercise an option appears, at the inception of the lease, to be reasonably assured. Deferred rent is included in both accrued liabilities and other non-current liabilities in the accompanying balance sheets. See "Leases" under Note 12 for additional information regarding our lease commitments.

Software Development Costs
	Software Development Costs
	Costs incurred to create software for internal use are expensed during the preliminary project stage and only costs incurred during the application development stage are capitalized. Upon placing the completed project in service, capitalized software development costs are amortized over the estimated useful life, which generally ranges from two to five years.
	Depreciation of capitalized software development costs for the years ended December 31, 2014, 2013 and 2012 was $4.3 million, $1.9 million and $2.9 million, respectively. The net book value of capitalized software development costs was $23.0 million and $13.3 million as of December 31, 2014 and 2013, respectively.

Assets and Liabilities of DG's TV Business
	Assets and Liabilities of DG's TV Business
	Pursuant to the Separation and Redemption Agreement (see Note 1), DG contributed to us substantially all of its television business current assets and certain other assets existing on February 7, 2014, and we agreed to assume substantially all of DG's television business liabilities that existed on February 7, 2014 or were attributable to periods up to and including February 7, 2014. The net assets contributed were recorded at $78.5 million. The details of these assets and liabilities outstanding as of December 31, 2014 were as follows (in thousands):

	Description		December 31, 2014
	Current assets of television business:
	Income tax receivables		$	1,943
	Trade accounts receivable			367
	Springbox revenue sharing			160

	Total		$	2,470


	Current liabilities of television business:
	Trade accounts payable		$	165
	Accrued liabilities			230

	Total		$	395


	Non-current liabilities of television business:
	Uncertain tax positions		$	260




Derivative Instruments
	Derivative Instruments
	We enter into foreign currency forward contracts and options to hedge a portion of the exposure to the variability in expected future cash flows resulting from changes in related foreign currency exchange rates between the New Israeli Shekel ("NIS") and the U.S. Dollar. These transactions are designated as cash flow hedges, as defined by Accounting Standards Codification ("ASC") Topic 815, "Derivatives and Hedging."
	ASC Topic 815 requires that we recognize derivative instruments as either assets or liabilities in our balance sheet at fair value. These contracts are Level 2 fair value measurements in accordance with ASC Topic 820, "Fair Value Measurements and Disclosures." For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss), net of taxes, and reclassified into earnings (various operating expenses) in the same period or periods during which the hedged transaction affects earnings.
	Our cash flow hedging strategy is to hedge against the risk of overall changes in cash flows resulting from certain forecasted foreign currency rent and salary payments during the next twelve months. We hedge portions of our forecasted expenses denominated in the NIS with a single counterparty using foreign currency forward contracts and options. At December 31, 2014, we had $14.3 million notional amount of foreign currency forward contracts and options outstanding that had a net fair value liability balance of $0.1 million ($0.2 million liability, net of a $0.1 million asset). The net liability is included in "accrued liabilities" and is expected to be recognized in our results of operations in the next twelve months. At December 31, 2013, we had $5.2 million notional amount of foreign currency forward contracts and options outstanding that had a net fair value asset balance of $0.1 million ($0.1 million asset, net of a $0.0 million liability). The vast majority of any gain or loss from hedging activities is included in our various operating expenses. As a result of our hedging activities, we incurred the following gains and losses in our results of operations (in thousands):

			Years Ended
			December 31,
			2014			2013			2012
	Hedging gain (loss) recognized in operations		$	115		$	865		$	(573	)
	It is our policy to offset fair value amounts recognized for derivative instruments executed with the same counterparty. In connection with our foreign currency forward contracts and options and other banking arrangements, we have agreed to maintain $1.5 million of cash in bank accounts with our counterparty, which we classify as restricted cash on our balance sheet.

Accumulated Other Comprehensive Income (Loss)
	Accumulated Other Comprehensive Income (Loss)

Goodwill
	Goodwill
	Goodwill represents the excess of the purchase price over the fair value of net identifiable assets acquired. We test goodwill for potential impairment at the reporting unit level on an annual basis, or more frequently if an event occurs or circumstances exist indicating goodwill may not be recoverable. Such events or circumstances may include operating results lower than previously forecasted or declines in future expectations of our operating results, or other significant negative industry trends. In evaluating goodwill for potential impairment, we perform a two-step process that begins with an estimate of the fair value of each reporting unit that contains goodwill (presently, we operate as a single reporting unit). We use a variety of methods, including discounted cash flow models, to determine fair value. In the event a reporting unit's carrying value exceeds its estimated fair value, evidence of a potential impairment exists. In such a case, the second step of the impairment test is required, which involves allocating the fair value of the reporting unit to its assets and liabilities, with the excess of fair value over allocated net assets representing the implied fair value of its goodwill. An impairment loss is measured as the amount, if any, by which the carrying value of a reporting unit's goodwill exceeds its implied fair value. During 2014 and 2012 we recorded goodwill impairment losses of $98.2 million and $219.6 million, respectively. See Note 5 for a discussion of the risk of a future impairment of our goodwill.

Long-Lived Assets
	Long-Lived Assets
	We assess our long-lived assets (other than goodwill), including acquired identifiable intangibles, for potential impairment whenever certain triggering events occur. Events that may trigger an impairment review include the following:
	•	significant underperformance relative to historical or projected future operating results;
	•	significant changes in the use of our assets or the strategy for our overall business; and
	•	significant negative industry or economic trends.
	If we determine the carrying value of our long-lived or intangible assets may not be recoverable based upon the occurrence of a triggering event, we assess the recoverability of these assets by determining whether amortization of the asset balance over its remaining life can be recovered through undiscounted future operating cash flows. Any impairment is determined based on a projected discounted cash flow model using a discount rate reflecting the risk inherent in the projected cash flows.
	We determine the useful lives of our identifiable intangible assets after considering the specific facts and circumstances related to each asset. Factors considered when determining useful lives include the contractual term of any agreement, the history of the asset, our long-term strategy for using the asset, any laws or other local regulations that could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have finite lives are generally amortized on a straight-line basis over their useful lives which generally range from 3 to 12 years. See "Intangible Assets" under Note 5 for additional information.

Foreign Currency Translation and Measurement
	Foreign Currency Translation and Measurement
	We translate the assets and liabilities of our non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Revenue and expenses for these subsidiaries are translated using the average exchange rates that were in effect during the period. Gains and losses from these translations are recognized in foreign currency translation, a component of accumulated other comprehensive income (loss) and part of stockholders' equity (business capital prior to the Spin-Off). Gains or losses from measuring foreign currency transactions into the functional currency are included in our statements of operations. For 2014, 2013 and 2012, we recognized foreign currency transaction gains and (losses) of ($1.2) million, $0.1 million and ($0.4) million, respectively.

Research and Development Expenses
	Research and Development Expenses
	Research and development expenses mainly include costs associated with maintaining our technology platform and are expensed as incurred.

Merger, Integration and Other Expenses
	Merger, Integration and Other Expenses
	Merger, integration and other expenses reflect the expenses incurred in (i) DG's Merger with Extreme Reach and our Spin-Off from DG, (ii) acquiring or disposing of a business, (iii) integrating an acquired operation (e.g., severance pay, office closure costs) into the Company and (iv) certain other items of income or expense not deemed to be part of our core operations. A summary of our merger, integration and other expenses is as follows (in thousands):

	Description		2014			2013			2012
	Merger and Spin-Off(1)		$	5,507		$	4,078		$	—
	Severance			1,200			569			2,970
	Integration and restructuring costs			2,400			321			1,655
	MediaMind preacquisition liability			—			720			—
	Acquisition legal and due diligence fees			275			—			644
	Recovery of TV business assets(2)			(3,078	)		—			—
	Other			—			189			683

	Total		$	6,304		$	5,877		$	5,952




	-1	Merger and Spin-Off includes costs incurred prior to the transactions while DG was evaluating strategic alternatives. See discussion of Merger and Spin-Off under "Separation from Digital Generation, Inc." in Note 1.
	-2	Represents a reduction in expense due to realizing more TV net assets than originally estimated at the time of the Spin-Off.
	Severance costs primarily relate to consolidating the workforces of MediaMind, EyeWonder, and Unicast and eliminating redundancy. All costs shown above were paid in the period the expense was recognized, or shortly thereafter. As of December 31, 2014, our integration efforts were substantially complete.

Share-Based Payments
	Share-Based Payments
	Subsequent to the Spin-Off, the compensation committee of our board of directors authorizes the issuance of stock options, time-based restricted stock units ("RSUs") and performance-based RSUs to our employees, directors and consultants. The committee approves grants only out of shares previously authorized by our stockholders.
	We recognize compensation expense based on the estimated fair value of the share-based payments. The fair value of our RSUs is based on the closing price of our common stock the day prior to the date of grant. The fair value of our stock options is calculated using the Black-Scholes option pricing model. Share-based awards that do not require future service are expensed immediately. Share-based awards that only require future service are amortized over the relevant service period on a straight-line basis. Share-based awards that require satisfaction of performance conditions, such as performance-based RSUs, are amortized over the performance period provided it is probable that the performance conditions will be satisfied. Subsequently, if the performance conditions are no longer probable of achievement, then all previously recognized compensation expense for that award will be reversed.
	Prior to the Spin-Off, we participated in DG's compensation programs that included equity-based incentive awards. Those equity-based awards related to shares of DG's common stock, not to our equity. For DG equity awards, we recognized an allocated cost equal to the cost recognized by DG. Allocations of share-based payments also arose from acquisitions when DG agreed to assume the share-based obligations of the acquired company on our behalf; such as the case in our acquisition of MediaMind. In connection with completing the Merger and Spin-Off, all of DG's outstanding equity awards became fully vested and, to the extent the award had an intrinsic value, were converted into shares of DG stock. Equity awards with no intrinsic value were cancelled. Following the Spin-Off, we did not assume any equity award previously issued by DG.
	We recognized $9.4 million, $6.4 million and $8.9 million in share-based compensation expense related to stock options, restricted stock and RSUs during the years ended December 31, 2014, 2013 and 2012, respectively. For 2014, $2.9 million relates to our equity awards and $6.5 million relates to the allocated cost of DG's equity awards. See Note 10.

Income Taxes
	Income Taxes
	Subsequent to the Spin-Off, we file our income tax returns on a stand-alone basis. Prior to the Spin-Off, our results of operations were included in the combined federal and state income tax returns of DG. For those periods, the income tax amounts reflected in the accompanying financial statements have been allocated to us based on taxable income (loss) directly attributable to us on a stand-alone basis. Management believes that the assumptions underlying the allocation of income taxes are reasonable. However, the amounts allocated for income taxes in the accompanying financial statements are not necessarily indicative of the amount of income taxes that would have been recorded had we operated as a separate, stand-alone entity during those periods. Prior to the Spin-Off, the U.S. federal and state tax losses generated by us were utilized by DG in its consolidated U.S. tax return. We are reflecting these U.S. federal and state tax losses as a distribution to DG for the year they were included in DG's U.S. tax returns.
	We establish deferred income tax assets and liabilities for temporary differences between the tax and financial accounting bases of our assets and liabilities. The tax effects of such differences are recorded in the balance sheet at the enacted tax rates expected to be in effect when the differences reverse. A valuation allowance is recorded to reduce the carrying amount of deferred tax assets if it is more likely than not that all or a portion of the asset will not be realized. The ultimate realization of our deferred tax assets is primarily dependent upon generating taxable income during the periods in which those temporary differences become deductible. The need for a valuation allowance is assessed each year. We forecast the reversal of our deferred tax assets and liabilities in determining the need for a valuation allowance. For 2014, 2013 and 2012, we recorded a valuation allowance.
	The tax balances and income tax expense recognized by us are based on our interpretation of the tax statutes of multiple jurisdictions and judgment. Differences between the anticipated and actual outcomes of these future tax consequences could have a material impact on our consolidated results of operations, financial position and cash flows.
	We account for uncertain tax positions in accordance with ASC 740, which contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining whether the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any 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 reevaluate our income tax positions periodically to consider factors such as changes in facts or circumstances, changes in or interpretations of tax law, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in recognition of a tax benefit or an additional charge to the tax provision.
	We include interest related to tax issues as part of income tax expense in our consolidated or combined financial statements. We record any applicable penalties related to tax issues within the income tax provision. See Note 8.

Business Combinations
	Business Combinations
	Business combinations are accounted for using the acquisition method. The purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values. Any excess purchase price over the fair value of the net identifiable assets acquired is recorded as goodwill. Operating results of an acquired business are included in our results of operations from the date of acquisition. See Note 3.

Financial Instruments and Concentration of Credit Risk
	Financial Instruments and Concentration of Credit Risk
	Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The vast majority of our cash and cash equivalents is held at large financial institutions in the United States and Israel that management believes to be of high credit quality. At certain financial institutions, our cash and cash equivalents regularly exceeds the federally insured limit. We have not experienced any losses on our cash and cash equivalents to date. We perform ongoing credit evaluations of our customers, generally do not require collateral and maintain a reserve for potential credit losses. We only recognize revenue when collection is reasonably assured. Our receivables are principally from advertising agencies and direct advertisers. Our receivables and the related revenues are not contingent on our customers' sales or collections. We believe the fair value of our accounts receivable approximate their carrying value. For the years ended December 31, 2014, 2013 and 2012, there was no single customer that accounted for more than 10% of our revenue. At December 31, 2014 and 2013, there was no single customer that accounted for more than 10% of our accounts receivables.

Israel Operations
	Israel Operations
	The majority of our research and development activities and a large portion of our accounting functions are performed in Herzliya, Israel. In total, about 28% of our workforce is located in Israel. As a result, we are subject to risks associated with operating in the Middle East.

Recently Adopted and Recently Issued Accounting Guidance
	Recently Adopted and Recently Issued Accounting Guidance
	Adopted
	Effective January 1, 2014, we adopted ASU 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" on a prospective basis. ASU 2013-11 amends the accounting guidance related to the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. The guidance requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset where a net operating loss, a similar tax loss, or a tax credit carryforward exists and certain criteria are met. The adoption of ASU 2013-11 did not have a material impact on our financial statements.
	Issued
	In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 modifies revenue recognition guidance for GAAP. Previous revenue recognition guidance in GAAP comprised broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes resulted in different accounting for economically similar transactions. In contrast, International Accounting Standards Board ("IASB") provided limited guidance on revenue recognition. Accordingly, the FASB and IASB initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards ("IFRS"). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps:
	Step 1: Identify the contract(s) with a customer.
	Step 2: Identify the performance obligations in the contract.
	Step 3: Determine the transaction price.
	Step 4: Allocate the transaction price to the performance obligations in the contract.
	Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.
	For Sizmek, the amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. An entity shall adopt the amendments in ASU 2014-09 by either (i) retrospectively adjusting each prior reporting period presented or (ii) retrospectively adjusting for the cumulative effect of initially applying ASU 2014-09 at the date of initial adoption. We have not as yet determined (i) the extent to which we expect ASU 2014-09 will impact our reported revenues or (ii) the manner in which it will be adopted.

	Expected term (years)(3)			5.94
	Expected annual dividends			None


	-1	Since our common stock has a limited trading history (trading began in February 2014), we based our expected volatility on the historical volatility of DG's common stock over a preceding period commensurate with the expected term of the option.
	-2	The risk free rate is based on the U.S. Treasury yield curve at the time of grant for periods consistent with the expected term of the option.
	-3	The expected term was calculated as the average between the vesting term and the contractual term, weighted by tranche. We used the simplified method discussed in ASC 718-10-S99-1 as we do not have sufficient historical data in order to calculate a more appropriate estimate.
