	1.  Basis of Presentation
	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 nearly 13,000 advertisers and over 5,000 agencies to audiences in about 70 countries, serving more than 1.5 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 the common stock of DG (“DG Common Stock”).  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 were 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, 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 pursuant to the separation and redemption agreement and related documents, 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, 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 believe we have benefited from sharing the corporate cost structure of DG rather than incurring such costs ourselves on a stand-alone basis. For the three months ended March 31, 2013, DG reported corporate overhead (excluding share-based compensation) of $5.8 million. The amount of such corporate overhead that was allocated to us in these carve-out financial statements was $2.3 million, in accordance with the allocation principals for preparing carve-out financial statements.  As a result, these carve-out financial statements include corporate overhead expenses which represent approximately 39% of DG’s total corporate overhead for the first quarter of 2013.  After the Spin-Off, we ultimately expect about 70% to 75% of DG’s total corporate overhead will shift to us, rather than the 39% that was allocated to us during the three months ended March 31, 2013.  Accordingly, we expect our corporate overhead costs as a stand-alone public company will be substantially greater than the amounts that were allocated to us in the carve-out financial statements prior to completion of the Spin-Off.
	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 was 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.

	2. General
	Principles of Consolidation and Combination
	The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and include the accounts of our subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation or combination.  For the period 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. These unaudited financial statements should be read in conjunction with the audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	These financial statements have been prepared by us without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.  However, we believe the disclosures are adequate to make the information presented not misleading.  The unaudited consolidated and combined financial statements reflect all adjustments, which are, in the opinion of management, of a normal and recurring nature and necessary for a fair presentation of our financial position as of the balance sheet dates, and the results of operations and cash flows for the periods presented.
	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 our 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 on 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.
	See Note 5 for a discussion of the risk of a future impairment of our goodwill.
	Assets and Liabilities of DG’s TV Business
	Pursuant to the Separation and Redemption Agreement, 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.  These net assets contributed were recorded at $75.7 million.  The details of these assets and liabilities outstanding as of March 31, 2014 were as follows (in thousands):
	Description	March 31, 2014
		(in thousands)
	Current assets of television business:
	Trade accounts receivable	$	15,904
	Income tax receivables	4,163
	Prepaid expenses	700
	Total	$	20,767
	Non-current assets of television business:
	Springbox revenue sharing	$	160
	Current liabilities of television business:
	Trade accounts payable	$	1,625
	Accrued liabilities	500
	Total	$	2,125
	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 foreign currency forward contracts and options.  At March 31, 2014, we had $3.7 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 net asset is included in “other current assets” and is expected to be recognized in our results of operations in the next twelve months.  As a result of our hedging activities, we incurred the following gains in our results of operations (in thousands):
		Three Months Ended March 31,
		2014			2013
	Hedging gain recognized in operations	$	86		$	199
	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.  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 $1.7 million of cash in bank accounts with our counterparty, which we classify as restricted cash on our balance sheet.
	Accumulated Other Comprehensive Income (Loss)
	Components of accumulated other comprehensive income (loss) (“AOCI” or “AOCL”), net of tax, for the three months ended March 31, 2014 and 2013 were as follows (in thousands):

Recently Adopted Accounting Guidance
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.

	3. Fair Value Measurements
	ASC 820, Fair Value Measurements and Disclosures, 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.
	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 March 31, 2014 and December 31, 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 an adjusted 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.  Under the arrangement, to the extent North Country’s revenues exceed a specified amount for the twelve months ended July 31, 2014; we are obligated to pay the North Country sellers a fee equal to a percentage of those revenues up to a maximum of $225,000. We have estimated North Country’s future revenues based on the historical revenues and certain other factors.  The following table provides a reconciliation of changes in the fair values of our Level 3 liabilities (in thousands):

	Balance at beginning of period	$	—
	Additions	225
	Balance at end of period	$	225
	Revenue and other earnout arrangements sometimes require a minimum level of performance (e.g., revenues, adjusted EBITDA) before any earnout payment becomes due.  Accordingly, there can be significant volatility in the earnout liability. Each reporting period, we update our estimates of the performance indicators (e.g., revenue, adjusted EBITDA) and the corresponding earnout levels achieved, discounted to their present values.  Changes in fair value are recorded in cost of revenues in the accompanying statements of operations.
	In connection with our acquisition of Republic Project, we agreed to a contingent consideration component of the purchase price based on 2014 and 2015 revenues and adjusted EBITDA.  The earnouts have minimum levels for revenue and adjusted EBITDA before any earnout payment becomes due.  As of March 31, 2014, we do not expect to make any payments with respect to the Republic Project contingent consideration arrangement.  See Note 4—Acquisition of Republic Project.

	4. Acquisition 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.
	The objective was to expand our product offerings and to better serve the advertising community. We expect to realize operating synergies from this transaction, and we expect Republic Project to create opportunities to sell its services to our customers. Republic Project has been included in our results of operations since the date of closing.
	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 tax purposes.

	We operate as a single reporting unit. Changes in the carrying value of our goodwill for the three months ended March 31, 2014 are as follows (in thousands):
		Goodwill		Accumulated			Net Carrying
				Impairment			Value
				Losses
	Balance at December 31, 2013	$	376,417	$	(242,331	)	$	134,086
	2014 activity	—		—			—
	Balance at March 31, 2014	$	376,417	$	(242,331	)	$	134,086
	We test 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. The goodwill impairment test involves a two-step process. In the first step, we compare the fair value of our online reporting unit to its carrying value. If the fair value of our online reporting unit exceeds its carrying value, goodwill is not impaired and no further testing is required. If the fair value of our online reporting unit 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 reporting unit’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 reporting unit was being acquired in a business combination. If the implied fair value of the reporting unit’s goodwill is less than the carrying value, the difference is recorded as an impairment loss. At December 31, 2013, we performed our annual goodwill impairment test for our online reporting unit and determined it was not impaired.  At March 31, 2014, we are not aware of any indicators of impairment of our goodwill.
	Risk of Future Impairment
	At December 31, 2013, based on a variety of methods including a discounted cash flow model (a Level 3 fair value measurement) that uses our internal forecast, we determined the fair value of our online reporting unit was only 5% in excess of its carrying value.  In preparing our discounted cash flow model, we make assumptions about future revenues and expenses to determine the cash flows that will result from the online reporting unit.
	As with any forecast, there is substantial risk the forecasted cash flows of our online reporting unit may fall short of our 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 decline sufficiently below the book value of our shareholders’ equity 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.

	Prior to our Spin-Off from DG on February 7, 2014, certain of our employees participated in DG’s equity based incentive programs.  Share-based compensation expense reflected in the accompanying financial statements up until February 7, 2014 relates to DG’s stock plan awards and not to our stock awards.  Immediately prior to completing the Spin-Off transaction, all outstanding equity awards became fully vested and were converted into shares of DG Common Stock, to the extent the award had an intrinsic value. 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 related to the stock awards (in thousands):

	Total	$	6,589	$	1,840
	Subsequent to the Spin-Off on February 7, 2014, Sizmek’s Compensation Committee granted (i) 134,760 performance-based Restricted Stock Units (“RSUs”), (ii) 89,839 time-based RSUs and (iii) 141,118 time-based stock options, to certain of our executive officers.  The RSUs and stock options expected to vest were valued at $2.2 million and $0.8 million, respectively.  The awards (i) vest over a three-year period, (ii) are subject to the employees’ continued employment with us, and (iii) with respect to the performance-based RSUs, are subject to reaching certain (a) revenue, (b) adjusted EBITDA and (c) free cash flow growth targets (i.e., performance conditions).  For the three months ended March 31, 2014, we recognized $0.1 million in share-based compensation expense related to the Sizmek equity awards.  Unrecognized compensation costs related to unvested RSUs and stock options were $2.9 million at March 31, 2014. These costs are expected to be recognized over the weighted average remaining vesting period of 2.8 years.

	7.  Income Taxes
	For the three months ended March 31, 2014, our effective tax rate was 2.7% compared to (16.3%) for the three months ended March 31, 2013. The effective tax rates for each period differ from the expected federal statutory rate of 35.0% as a result of state and foreign income taxes; certain non-deductible expenses; and valuation allowances in the U.S. and state jurisdictions within the U.S.  The valuation allowance creates an effective tax rate of zero for income or loss earned in the U.S., substantially reducing our effective tax rate.
	For the period from January 1, 2014 through the Spin-Off from DG on February 7, 2014, our operations were included in the consolidated income tax returns of DG.  However, income taxes were calculated and provided for Sizmek on a separate return basis for all periods presented.  The amount of assets and liabilities related to income taxes prior to the Spin-Off that were retained by Sizmek are reflected in our consolidated balance sheet.
	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.  During the three months ended March 31, 2014, there were no additional uncertain tax positions. Interest and penalties related to uncertain tax positions are recognized in income tax expense.  For the three months ended March 31, 2014, we recognized less than $0.1 million of interest or penalties related to uncertain tax positions in our financial statements compared to less than $0.1 million for the three months ended March 31, 2013.
	The changes in uncertain tax positions for the three months ended March 31, 2014 and 2013 were as follows (in thousands):
		Three Months Ended March 31,

	Changes to tax positions related to current or prior periods	—		—
	Balance at end of period	$	1,701	$	1,801
	If we reduced our reserve for uncertain tax positions, it would result in us recognizing a tax benefit.
	As of March 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 March 31, 2014 and December 31, 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 2010 through 2013 remain open to examination.  Israeli and United Kingdom income tax returns remain open to examination for 2007 through 2013 and 2008 through 2013, respectively.  Historically, our operating results have been included DG’s U.S. federal and state tax returns or tax returns of non-U.S. jurisdictions.  Effective for the period beginning February 8, 2014, 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 the 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, we believe both 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.

	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 as of the beginning of each period presented prior to the Spin-Off in the calculation of weighted-average shares outstanding.

	Prior to the Spin-Off, DG provided certain management and administrative services to us.  These services include, 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 allocated merger, integration and other expenses to us largely based on revenues.  The allocations of such expenses to us were as follows:
		Three Months Ended March 31,

	Management and administrative services	$	514		$	1,726

	Total	$	4,552		$	2,236
	The above expense allocations do not include share-based compensation which is discussed in Note 6.
	Included in the above are allocated 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 consistent with how the underlying employee’s salary and other compensation costs have been recorded.
	DG and the Company consider the allocated cost for corporate services, employee benefits and incentives to be reasonable based on the utilization of the services. However, we believe the allocated cost for these services differs from what would have resulted from transactions among third parties if we were a stand-alone entity.  See Note 1—Basis of Presentation — Carve-out Financial Statements Prior to Spin-Off regarding our expectation that Sizmek’s corporate overhead expenses will increase following the Spin-Off.
	In addition, DG primarily used a centralized approach to cash management and financing of its operations with all related activity between DG and us reflected in business capital in our December 31, 2013 balance sheet.  The transactions included:
	·                  cash deposits from our customers to us that were transferred to DG’s bank accounts on a regular basis;
	·                  cash infusions from DG to fund our operations, capital expenditures or 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.

	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 May 29, 2013, a purported shareholder derivative suit was filed captioned Boyler v. Certain Officers and Directors of Digital Generation, Inc., Case No: DC-13-05971-I, in the 162nd Judicial District Court of Dallas County, Texas. The action alleges breach of fiduciary duty, abuse of control and gross mismanagement related to DG’s acquisition of several online media companies, its subsequent write-down of these assets, and the inability of a Special Committee of the Board of Directors to find a strategic buyer for DG. The suit seeks damages, restitution, disgorgement, attorneys’ fees and corporate governance reforms. On March 4, 2014, the plaintiff filed a notice of nonsuit without prejudice.
	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, a Stipulation for Extension of Time and Order (the “Scheduling Order”) providing a proposed briefing schedule was ordered by the Court. On February 26, 2014, in accordance with the Scheduling Order, Plaintiff filed a Motion to Remand the action to the Supreme Court of the State of New York, County of New York.
	The Company believes Plaintiff’s allegations and its Request are without merit and intends to defend this action vigorously. We believe the purported claims and our defense costs will qualify for reimbursement under DG’s and/or our insurance coverage, which are subject to the applicable deductible and the limits of the policies.

All significant intercompany balances and transactions have been eliminated in consolidation or combination.  For the period 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. These unaudited financial statements should be read in conjunction with the audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

On an ongoing basis, we evaluate our estimates, including those related to the recoverability and useful lives of our 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 on 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.

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 foreign currency forward contracts and options.  At March 31, 2014, we had $3.7 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 net asset is included in “other current assets” and is expected to be recognized in our results of operations in the next twelve months.  As a result of our hedging activities, we incurred the following gains in our results of operations (in thousands):
		Three Months Ended March 31,

The vast majority of any gain or loss from hedging activities is included in our various operating expenses.  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 $1.7 million of cash in bank accounts with our counterparty, which we classify as restricted cash on our balance sheet.

Recently Adopted Accounting Guidance	'
	Recently Adopted Accounting Guidance
	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.
