Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Basis of Presentation and Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and accounts are eliminated in consolidation.
	Certain amounts from the prior year balance sheet have been recasted. In connection with the Spatial Systems Nominees PTY LTD ("Spatial") acquisition, the consolidated balance sheet at December 31, 2012 has been recast to include retrospective purchase accounting adjustments. These adjustments pertain to measurement period adjustments during the period ended November 30, 2013, based on the reclassification and valuation of assets acquired and liabilities assumed in the Spatial acquisition. The effect on the consolidated balance sheet at December 31, 2012, as a result of the recast, is a decrease in accounts receivable of $2.6 million, an increase in prepaid expenses and other assets of $5.0 million, an increase in goodwill of $11.8 million, an increase in accrued expenses of $4.6 million, and an increase in deferred revenues of $9.6 million.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
	Revenue Recognition and Deferred Revenue
	The Company provides services principally on a transactional or subscription basis or, at times, on a fixed fee basis and recognizes the revenues as the services are performed or delivered as described below:
	Transactional and Subscription Service Arrangements:    Transaction and subscription revenues represented approximately 70%, 67%, and 77% of revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Transaction and subscription revenues consist of revenues derived from the processing of transactions through the Company's service platforms, providing enterprise portal management services on a subscription basis and maintenance agreements on software licenses. Transaction service arrangements include services such as processing equipment orders, new account set-up and activation, number port requests, credit checks and inventory management. Subscription services include hosting and storage and the related maintenance support for those services.
	Transaction revenues are principally based on a contractual price per transaction and are recognized based on the number of transactions processed during each reporting period. Revenues are recorded based on the total number of transactions processed at the applicable price established in the relevant contract. The total amount of revenues recognized is based primarily on the volume of transactions. Subscription revenues are recorded on a straight-line basis over the life of the contract for subscription services and maintenance agreements.
	Many of the Company's contracts guarantee minimum volume transactions from the customer. In these instances, if the customer's total transaction volume for the period is less than the contractual amount, the Company records revenues at the minimum guaranteed amount. At times, transaction revenues may also include billings to customers that reimburse the Company based on the number of individuals dedicated to processing transactions. Set-up fees for transactional service arrangements are deferred and recognized on a straight-line basis over the life of the contract since these amounts would not have been paid by the customer without the related transactional service arrangement. Revenues are presented net of discounts, which are volume level driven, or credits, which are performance driven, and are determined in the period in which the volume thresholds are met or the services are provided.
	Professional Service and Software License Arrangements:    Professional service and software license revenues represented approximately 30%, 33% and 23% of revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Professional services include process and workflow consulting services and development services. Professional services, when sold with non-software transactional or subscription service arrangements, are accounted for separately when the professional services have value to the customer on a standalone basis. Professional services, when sold with software transactional or subscription service arrangements are accounted for separately when the professional services have value to the customer on a standalone basis and there is objective and reliable evidence of fair value of the professional services. When accounted for separately, professional service revenues are recognized on a monthly basis, as services are performed and all other elements of revenue recognition have been satisfied.
	In determining whether professional service revenues can be accounted for separately from transaction or subscription service revenues, the Company considers the following factors for each professional services agreement: availability of the professional services from other vendors, whether objective and reliable evidence of fair value exists of the undelivered elements, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the transaction or subscription service start date and the contractual independence of the transactional or subscription service from the professional services.
	If a professional service arrangement were not to qualify for separate accounting, the Company would recognize the professional service revenues ratably over the remaining term of the transaction or subscription agreement.
	Revenue from software license arrangements is recognized when the license is delivered to its customers and all of the software revenue recognition criteria are met. When software arrangements include multiple elements, the arrangement consideration is allocated at the inception to all deliverables using the residual method providing the Company has vendor specific objective evidence (VSOE) on all undelivered elements. The Company determines VSOE for each element based on historical stand-alone sales to third parties. When sold with non-software transaction or subscription service arrangements, the arrangement consideration is allocated at the inception of an arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable's selling price. The selling price used for each deliverable will be based on VSOE if available, third-party evidence (TPE) if vendor-specific objective evidence is not available, or estimated selling price (ESP) if neither vendor-specific objective evidence nor third-party evidence is available. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The Company determines ESP by considering multiple factors, including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives, and pricing practices. ESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.
	While the Company follows specific and detailed rules and guidelines related to revenue recognition, it makes and uses management judgments and estimates in connection with the revenue recognized in any reporting period, particularly in the areas described above, as well as collectability. If management made different estimates or judgments, differences in the timing of the recognition of revenue could occur.
	Deferred Revenue:    Deferred revenues primarily represent billings to customers for services in advance of the performance of services, with revenues recognized as the services are rendered, and also includes the fair value of deferred revenues recorded as a result of acquisitions.
	Service Level Standards
	Pursuant to certain contracts, the Company is subject to service level standards and to corresponding penalties for failure to meet those standards. All performance-related penalties are reflected as a corresponding reduction of the Company's revenues. These penalties, if applicable, are recorded in the month incurred and were insignificant for the years ended December 31, 2013, 2012 and 2011, respectively.
	Concentration of Credit Risk
	The Company's financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable. The Company maintains its cash and cash equivalents at several major financial institutions. The Company has not experienced any realized losses in such accounts and believes it is not exposed to any significant credit risk related to cash, cash equivalents and securities. The Company's cash equivalents and short-term marketable securities consist primarily of money market funds, certificates of deposit, and municipal and corporate bonds. The Company believes that concentration of credit risk with respect to accounts receivable is limited because of the creditworthiness of the Company's major customers.
	The Company's top five customers accounted for 77%, 76% and 86% of net revenues for 2013, 2012 and 2011, respectively. The Company's top five customers accounted for 76% and 67% of accounts receivable at December 31, 2013 and 2012, respectively. Of these customers, AT&T and Verizon Wireless each accounted for more than 10% of the Company's revenues in 2013. The loss of either AT&T or Verizon as a customer would have a material negative impact on the Company. The Company believes that if either AT&T or Verizon terminated their relationships with Synchronoss, AT&T and Verizon would encounter substantial costs in replacing Synchronoss' transaction management solutions.
	Fair Value of Financial Instruments and Liabilities
	The Company includes disclosures of fair value information about financial instruments and liabilities, whether or not recognized on the balance sheet, for which it is practicable to estimate that value. Due to their short-term nature, the carrying amounts reported in the financial statements approximate the fair value for cash and cash equivalents, marketable securities, accounts receivable and accounts payable.
	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with a maturity of three months or less at the date of acquisition to be cash equivalents.
	Marketable Securities
	Marketable securities consist of fixed income investments with a maturity of greater than three months and enhanced money market funds. These investments are classified as available-for-sale and are reported at fair value on the Company's balance sheet. The Company classifies its securities with maturity dates of 12 months or more as long term. Unrealized holding gains and losses are reported within accumulated other comprehensive loss as a separate component of stockholders' equity. If a decline in the fair value of a marketable security below the Company's cost basis is determined to be other than temporary, such marketable security is written down to its estimated fair value as a new cost basis and the amount of the write-down is included in earnings as an impairment charge. The Company has recorded temporary changes in fair value of the marketable securities but has not recorded other-than-temporary charges for the periods presented herein.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable consist of amounts due to the Company from normal business activities. The Company maintains an allowance for estimated losses resulting from the inability of its customers to make required payments. The Company estimates uncollectible amounts based upon historical bad debts, current customer receivable balances, the age of customer receivable balances, the customer's financial condition and current economic trends.
	Property and Equipment
	Property and equipment and leasehold improvements are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 5 years, or the lesser of the related initial term of the lease or useful life for leasehold improvements. Amortization of property and equipment recorded under a capital lease is included with depreciation expense. Expenditures for routine maintenance and repairs are charged against operations. Major replacements, improvements and additions are capitalized.
	Business Combinations
	The Company accounts for business combinations in accordance with the acquisition method. The acquisition method of accounting requires that assets acquired and liabilities assumed be recorded at their fair values on the date of a business acquisition. The Company's consolidated financial statements and results of operations reflect an acquired business from the completion date of an acquisition.
	The judgments that the Company makes in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact net income in periods following a business combination. The Company generally uses either the income, cost or market approach to aid in its conclusions of such fair values and asset lives. The income approach presumes that the value of an asset can be estimated by the net economic benefit to be received over the life of the asset, discounted to present value. The cost approach presumes that an investor would pay no more for an asset than its replacement or reproduction cost. The market approach estimates value based on what other participants in the market have paid for reasonably similar assets. Although each valuation approach is considered in valuing the assets acquired, the approach ultimately selected is based on the characteristics of the asset and the availability of information.
	The Company records contingent consideration resulting from a business combination at its fair value on the acquisition date. Each reporting period thereafter, the Company revalues these obligations and records increases or decreases in their fair value as an adjustment to net change in contingent consideration obligation within the consolidated statement of income. Changes in the fair value of the contingent consideration obligation can result from updates in the achievement of financial targets and changes to the weighted probability of achieving those future financial targets. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, any change in the assumptions described above, could have a material impact on the amount of the net change in contingent consideration obligation that the Company records in any given period.
	Goodwill and Other Intangible Assets
	Goodwill represents the excess of the purchase price over the fair value of assets acquired, including other definite-lived intangible assets. Goodwill is not amortized, but reviewed annually for impairment or upon the occurrence of events or changes in circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount. There were no impairment charges recognized during the years ended December 31, 2013, 2012 and 2011.
	Intangible assets that do not have indefinite lives (primarily technology and customer relationships) are amortized over their useful lives. All of intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reevaluates the useful life determinations for these intangible assets each year to determine whether events and circumstances warrant a revision in their remaining useful lives.
	Impairment of Long-Lived Assets
	A review of long-lived assets for impairment is performed when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If an indication of impairment is present, the Company compares the estimated undiscounted future cash flows to be generated by the asset to the asset's carrying amount. If the undiscounted future cash flows are less than the carrying amount of the asset, the Company records an impairment loss equal to the amount by which the asset's carrying amount exceeds its fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. There were no impairment charges recognized during the years ended December 31, 2013, 2012 and 2011.
	Cost of Services
	Cost of services includes all direct materials, direct labor and those indirect costs related to revenues such as indirect labor, materials and supplies and facilities cost, exclusive of depreciation expense.
	Research and Development
	Research and development costs are expensed as incurred, unless they meet U.S. GAAP criteria for deferral and amortization. Software development costs incurred prior to the establishment of technological feasibility do not meet these criteria, and are expensed as incurred. Amortization of software development costs is computed using the straight-line method over the estimated useful lives of the assets, 3 and 5 years. As of December 31, 2013, the Company had $1.8 million of unamortized software development costs and $1.2 million of amortization expense which was recognized during 2013. As of December 31, 2012, the Company had $2.0 million of unamortized software development costs and $1.3 million of amortization expense which was recognized during 2012. Research and development expense consists primarily of costs related to personnel, including salaries and other personnel-related expenses, consulting fees and the cost of facilities, computer and support services used in service technology development. The Company also expenses costs relating to developing modifications and minor enhancements of its existing technology and services.
	Income Taxes
	Since the Company conducts operations on a global basis, its effective tax rate has and will depend upon the geographic distribution of its pre-tax earnings among locations with varying tax rates. The Company accounts for the effects of income taxes that result from its activities during the current and preceding years. Under this method, deferred income tax liabilities and assets are based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse or be utilized. The realization of deferred tax assets is contingent upon the generation of future taxable income. A valuation allowance is recorded if it is "more likely than not" that a portion or all of a deferred tax asset will not be realized.
	The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The amount of the accrual for which an exposure exists is measured by determining the amount that has a greater than 50 percent likelihood of being realized upon the settlement of the position. Components of the reserve are classified as a long-term liability in the consolidated balance sheets. The Company records interest and penalties accrued in relation to uncertain tax benefits as a component of interest expense. The Company expects that the amount of unrecognized tax benefits will change during 2014; however, the Company does not expect the change to have a significant impact on its results of operations or financial position.
	While the Company believes it has identified all reasonably identifiable exposures and that the reserve that the Company has established for identifiable exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures may be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause the Company to either materially increase or reduce the carrying amount of its tax reserves. In general, tax returns for the year 2010 and thereafter are subject to future examination by tax authorities.
	The Company's policy has been to leave its cumulative unremitted foreign earnings invested indefinitely outside the United States, and the Company intends to continue this policy. As such, taxes have not been provided on any of the remaining accumulated foreign unremitted earnings. If the cumulative unremitted foreign earnings exceed the amount the Company intends to reinvest in foreign countries in the future, the Company would provide for taxes on such excess amount.
	Foreign Currency
	Prior to the third quarter of 2013, several of the Company's subsidiaries that operate outside the U.S. used the U.S. dollar as the functional currency. Effective July 1, 2013, the Company changed the functional currencies of those subsidiaries that operate outside the U.S. to their local currency. This change was the result of a change in the Company's international operations and economic strategies driven by the implementation of a global financial system that has allowed the Company's foreign operations to become self-contained and integrated within their resident countries and to the local currency.
	The functional currency is translated into U.S. dollars for balance sheet accounts using the month end rates in effect as of the balance sheet date and average exchange rate for revenue and expense accounts for each respective period. The translation adjustments are deferred as a separate component of stockholders' equity, within accumulated other comprehensive income. Gains or losses resulting from transactions denominated in foreign currencies are included in other income or expense, within the consolidated statements of income. The effects of the change in functional currency were not material to the Company's consolidated financial statements for all years presented.
	Comprehensive Income
	Reporting on comprehensive income requires components of other comprehensive income, including unrealized gains or losses on available-for-sale securities, to be included as part of total comprehensive income. Comprehensive income is comprised of net income, translation adjustments and unrealized gains and losses on available-for-sale securities. The components of comprehensive income are included in the statements of comprehensive income.
	Basic and Diluted Net Income Attributable to Common Stockholders per Common Share
	The Company calculates basic and diluted per share amounts based on net earnings adjusted for the effects to earnings that would result if contingently issuable shares related to contingent consideration to be settled in the Company's stock were reported as equity for the periods presented. Basic earnings per share is calculated by using the weighted average number of common shares outstanding during the period. The diluted earnings per share calculation is based on the weighted average number of shares of common stock outstanding adjusted for the number of additional shares that would have been outstanding had all potentially dilutive common shares been issued. Potentially dilutive shares of common stock include stock options, non-vested share awards and contingently issuable shares related to contingent consideration to be settled in stock. The dilutive effects of stock options and restricted stock awards are based on the treasury stock method. The dilutive effects of the contingent consideration to be settled in stock are calculated as if the contingently issuable shares were outstanding as of the beginning of the period. The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income attributable to common stockholders per common share. Stock options that are anti-dilutive and excluded from the following table totaled 1,367, 1,840, and 947 for the years ended December 31, 2013, 2012 and 2011, respectively.

Stock-Based Compensation
As of December 31, 2013, the Company maintains three stock-based compensation plans. The Company utilizes the Black-Scholes pricing model to determine the fair value of stock options on the dates of grant. Restricted stock awards are measured based on the fair market values of the underlying stock on the dates of grant, unless the awards are subject to market conditions, in which case the Company uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved. The Company recognizes stock-based compensation over the requisite service period with an offsetting credit to additional paid-in capital.
For the Company's performance restricted stock awards the Company estimates the number of shares the recipient is to receive by applying a probability of achieving the performance goals. The actual number of shares the recipient receives is determined at the end of the annual performance period based on the results achieved versus goals based on its annual performance targets, such as operating income. Once the number of awards is determined, the compensation cost is fixed and continues to be recognized using the accelerated attribution recognition over the requisite service period for each vesting tranche.
The Company classifies benefits of tax deductions in excess of the compensation cost recognized (excess tax benefits) as a financing cash inflow with a corresponding operating cash outflow. The Company included $3.0 million, $6.9 million and $3.6 million of excess tax benefits as a financing cash inflow for the years ended December 31, 2013, 2012 and 2011, respectively.
Impact of Recently Issued Accounting Standards
In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-02 which requires additional disclosures regarding the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 requires an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. This guidance is effective for reporting periods beginning after December 15, 2012. The Company adopted this guidance effective January 1, 2013. The Company's adoption of this standard did not have a significant impact on its consolidated financial statements.
In March 2013, the FASB issued ASU 2013-05, which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. The revised standard is effective for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
In July 2013, the FASB issued ASU 2013-11, which provides that a liability related to an unrecognized tax benefit would be offset against a deferred tax asset instead of presented gross for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. This new guidance is effective for fiscal years beginning after December 15, 2013. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
Segment and Geographic Information
The Company's chief operating decision-maker is the Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources. Accordingly, the Company has determined that it currently operates in one business segment: providing cloud solutions and software-based activation for connected devices globally. The Company is not organized by market and is managed and operated as one business. A single management team reports to the chief operating decision maker who comprehensively manages the entire business. The Company does not operate any separate lines of business or separate business entities with respect to its services. Accordingly, the Company does not accumulate a complete set of discrete financial information with respect to separate service lines and does not have separately reportable segments. Although, the Company operates in North America, Europe and Asia-Pacific a majority of the Company's revenue and long lived assets are in the U.S.
Revenues by geography are based on the billing addresses of the Company's customers. The following tables set forth revenues and property and equipment, net by geographic area:

	Strumsoft, Inc. ("Strumsoft")
	On November 6, 2013, the Company acquired 100% of the capital stock of Strumsoft (USA), Inc., a California corporation and Strumsoft (India) Pvt. Ltd., an India company for a total cash consideration of $11.0 million and issued approximately 33 shares of the Company's Common Stock. The total cash consideration was comprised of $10.2 million for the purchase of all the shares of Strumsoft and $774 for the estimated surplus working capital on the date of purchase. The 33 shares of the Company's Common Stock were valued at approximately $1.1 million based on the Company's November 6, 2013 closing stock price per shares. In addition, the Company potentially may make payments ("Strumsoft Earn-out") totaling up to approximately $6.0 million based on the ability to achieve a range of business objectives for the period from January 1, 2014 through December 31, 2014. The maximum that could be paid to existing employees of Strumsoft is $2.0 million and actual amounts will be recorded as compensation expense over the service period. Strumsoft is engaged in the business of providing consultancy services for software development and data processing.
	Management determined the preliminary fair value of net assets acquired during the fourth quarter of 2013. Accordingly, on November 6, 2013 the Company recorded $4.2 million representing the initial fair value estimate of the contingent consideration that will be earned through December 31, 2014. At December 31, 2013 there was no change in the fair value of the contingent consideration. The fair value of this liability is based on future sales projections of Strumsoft and weighting the probability of the sales outcome for the period ended December 31, 2014. These fair value measurements were based on significant inputs not observed in the market and thus represented a Level 3 measurement.
	The goodwill recorded in connection with this acquisition is based on (i) the expertise in cloud computing held by key leaders of Strumsoft, and (ii) intangible assets that do not qualify for separate recognition such as Strumsoft's assembled workforce. The goodwill acquired will not be deductible for tax purposes. The results of Strumsoft's operations have been included in the consolidated financial statements since the acquisition date. Pro forma results of operations for the acquisition have not been presented because the effects of the acquisition were not material to the Company's prior financial statements.
	The Company believes that Strumsoft will help strengthen its user design and messaging development and augment the Company's cloud services offerings and mobile development. In addition, the acquisition of Strumsoft is expected to help increase the Company's penetration of its domestic customer base.

	On December 24, 2012 the Company acquired 100% of the capital stock of Newbay, an Ireland company, and its subsidiaries, for cash consideration of $55.5 million. Newbay had operations in Europe and the U.S.
	The purchase price was allocated to the tangible assets acquired and liabilities assumed based upon their fair values at the acquisition date.

Spatial Systems Nominees PTY LTD("Spatial")
On November 30, 2012, the Company acquired 100% of the capital stock of Spatial, an Australian company with operations in the U.S., for total cash consideration of $30.6 million and issued approximately 240 shares of the Company's Common Stock. The total cash consideration was comprised of $30.0 million for the purchase of all of the shares of Spatial and $625 for the estimated surplus working capital on the date of purchase. Of the 240 shares of the Company's Common Stock issued, only a portion valued at approximately $1.4 million based on the Company's November 30, 2012 closing stock price per share was considered purchase price. The remaining value of the shares will be recognized as compensation expense and amortized over the service period of three years. In addition, the Company could have potentially made payments totaling up to approximately $5.0 million in cash and issue up to 260 shares of stock based on the ability to achieve a range of business objectives for the period from December 1, 2012 through November 30, 2013. However, these objectives were not achieved due to the timing of projected revenues financial milestones required to receive the expected payout and, therefore, the Company has no further obligation to the former Spatial stockholders.
The purchase price was allocated to the tangible assets acquired and liabilities assumed based upon their fair values at the acquisition date. The excess of the purchase price over the net tangible assets and liabilities, approximately $35.9 million, was recorded as goodwill, which is not tax deductible.
Allocation of Consideration Transferred
Total purchase price is summarized as follows:
	November 30, 2012
Cash consideration	$	30,000
Working Capital Surplus		625
Value of Synchronoss common stock issued		1,386
Estimated fair value of the Earn-out payments		4,600
Total purchase price	$	36,611
The Company prepared an initial determination of the fair value of assets acquired and liabilities assumed as of the acquisition date using preliminary information. In accordance with Accounting Standards Codification 805, during the measurement period an acquirer shall retrospectively adjust the provisional amounts recognized at the acquisition date to reflect information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of the acquisition date. Accordingly, the Company has recognized measurement period adjustments made during the first quarter of 2013 to the fair value of certain assets acquired and liabilities assumed as a result of the further refinements in the Company's provisional amounts. These adjustments were retrospectively applied to the November 30, 2012 acquisition date balance sheet. The effect of these adjustments on the preliminary purchase price allocation was a decrease in accounts receivable of $2.6 million, an increase in prepaid expenses and other assets of $5.0 million, an increase to goodwill of $11.8 million, an increase in accrued expenses of $4.6 million, and an increase to deferred revenues of $9.6 million. None of the adjustments had a material impact on the Company's previously reported results of operations.

	4. Fair Value Measurements of Assets and Liabilities
	The Company classifies marketable securities as available-for-sale. The fair value hierarchy established in the guidance adopted by the Company prioritizes the inputs used in valuation techniques into three levels as follows:
	•
	Level 1—Observable inputs—quoted prices in active markets for identical assets and liabilities;
	•
	Level 2—Observable inputs other than the quoted prices in active markets for identical assets and liabilities—includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and
	•
	Level 3—Unobservable inputs—includes amounts derived from valuation models where one or more significant inputs are unobservable and require the Company to develop relevant assumptions.
	The following is a summary of assets and liabilities held by the Company and their related classifications under the fair value hierarchy at December 31, 2013 and 2012:
		December 31,
		2013			2012
	Level 1(A)	$	68,911		$	41,395
	Level 2(B)		8,694			15,474
	Level 3(C)		(4,490	)		(8,379	)
	Total	$	73,115		$	48,490
	(A)
	Level 1 assets include money market funds and enhanced income money market funds which are classified as cash equivalents and marketable securities, respectively.
	(B)
	Level 2 assets include certificates of deposit, municipal bonds and corporate bonds which are classified as marketable securities.
	(C)
	Level 3 liabilities include the contingent consideration obligation.
	The Company utilizes the market approach to measure fair value for its financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The Company's marketable securities investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. No transfers of assets between Level 1 and Level 2 of the fair value measurement hierarchy occurred during the year ended December 31, 2013.
	The aggregate fair value of available for sale securities and aggregate amount of unrealized gains and losses for available for sale securities at December 31, 2013 were as follows:
					Aggregate
					Amount
		Aggregate			of Unrealized
		Fair Value			Gains			Losses
	Due in one year or less	$	9,105		$	5		$	(32	)
	Due after one year, less than five years		4,988			11			(2	)
		$	14,093		$	16		$	(34	)
	The aggregate fair value of available for sale securities and aggregate amount of unrealized gains and losses for available for sale securities at December 31, 2012 were as follows:
					Aggregate
					Amount
		Aggregate			of Unrealized
		Fair Value			Gains			Losses
	Due in one year or less	$	20,188		$	18		$	(41	)
	Due after one year, less than five years		653			1			(1	)
		$	20,841		$	19		$	(42	)
	Unrealized gains and losses are reported as a component of accumulated other comprehensive loss in stockholders' equity. The net unrealized gain net of tax was $2 and $123 as of December 31, 2013 and 2012, respectively. During the year ended December 31, 2012, the Company received $52.8 million in proceeds from the sale of its marketable securities and recognized $264 of net losses. There were no sales of marketable securities during the year ended December 31, 2013. The cost of securities sold is based on specific identification method. The Company evaluates investments with unrealized losses to determine if the losses are other than temporary. The Company has determined that the gross unrealized losses at December 31, 2013 and 2012 are temporary. In making this determination, the Company considered the financial condition, credit ratings and near-term prospects of the issuers, the underlying collateral of the investments, and the magnitude of the losses as compared to the cost and the length of time the investments have been in an unrealized loss position. Additionally, while the Company classifies the securities as available for sale, the Company does not currently intend to sell such investments and it is more likely than not to recover the carrying value prior to being required to sell such investments.
	The Company determined the fair value of the contingent consideration obligation based on a probability-weighted income approach derived from quarterly revenue estimates and a probability assessment with respect to the likelihood of achieving the various performance criteria. The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement. The significant unobservable inputs used in the fair value measurement of the Company's contingent consideration obligation are the probabilities of achieving certain financial targets and contractual milestones. Significant increases (decreases) in any of those probabilities in isolation may result in a higher (lower) fair value measurement. No changes in valuation techniques occurred during the year ended December 31, 2013. During the year ended December 31, 2013, the Company recognized a $5.3 million reduction of the contingent consideration obligation driven by the settlement of the SpeechCycle, Inc. ("SpeechCycle") Earn-out and the Spatial Earn-out not being achieved due to the timing of projected revenues financial milestones required to receive the expected payout. During the year ended December 31, 2013, the Company paid approximately $2.6 million to the former stockholders of SpeechCycle and employees at the completion of the service period for the SpeechCycle contingent consideration obligation and approximately $1.0 million to the former stock-holders of Miyowa, S.A. ("Miyowa") and employees at the completion of the Miyowa contingent consideration obligation.
	The changes in fair value of the Company's Level 3 contingent consideration obligation during the year ended December 31, 2013 were as follows:
		Level 3
	Balance at December 31, 2012	$	8,379
	Fair value adjustment to contingent consideration obligation included in net income		(5,324	)
	Earn-out compensation due to SpeechCycle employees		511

	8. Stock Plans
	As of December 31, 2013, the Company maintains three stock incentive plans, the 2000 Plan, the 2006 Plan and the 2010 Plan. The Company's Board of Directors administers the 2000 Plan, the 2006 Plan, and the 2010 Plan and is responsible for determining the individuals to be granted options or shares, the number of options or shares each individual will receive, the price per share and the exercise period of each option.
	Under the 2000 Plan, the Company has the ability to provide employees, outside directors and consultants an opportunity to acquire a proprietary interest in the success of the Company or to increase such interest by receiving options or purchasing shares of the Company's stock at a price not less than the fair market value at the date of grant for incentive stock options and a price not less than 30% of the fair market value at the date of grant for non-qualified options. Under the 2006 Plan and 2010 Plan, the Company may grant to its employees, outside directors and consultants awards in the form of incentive stock options, non-qualified stock options, shares of restricted stock and stock units or stock appreciation rights. During the year ended December 31, 2013, options to purchase 624 shares of common stock were granted under the 2006 Plan. Under the Company's Plans, options may be exercised in whole or in part for 100% of the shares subject to vesting at any time after the date of grant. Options under the Company's 2000 and 2006 Plans generally vest 25% on the first year anniversary of the date of grant plus an additional 1/48th for each month of continuous service thereafter. Options under the Company's 2010 Plan generally vest the first 50% on the second year anniversary from July 19, 2010 and an additional 1/48th for each month of continuous service thereafter.
	During 2013, the Company issued approximately 308 shares of restricted stock and increased the amount reserved to grant 128 shares of stock related to the 2012 performance share grant. As of December 31, 2013, the Company had a remaining 187 shares of restricted stock reserved for the 2013 performance share grant. The actual number of shares to be issued, which could range from 0 to 187, is dependent upon the Company's revenue and operating income levels compared to targets. For certain executives, the 2013 and 2012 performance share grants also contain a market condition that adjusts the number of performance shares otherwise earned based on the achievement of operating targets. Specifically, the percentage of the target performance shares earned based on achievement of operating targets could be adjusted (upward or downward) based on the Company's Total Shareholder Return (TSR) performance, as compared to the TSR of the companies in the S&P 500 at the beginning and end of the following year. The additional shares, if any, will be issued in early 2014. As of December 31, 2013, there were 3,749 shares available for grant or award under the Company's Plans.
	The Company utilizes the Black-Scholes option pricing model for determining the estimated fair value for stock option awards. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility was calculated based on a weighted-average of the Company's historical stock information. The average expected life was determined using the Company's historical data. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The Company has never declared or paid cash dividends on its common or preferred equity and does not anticipate paying any cash dividends in the foreseeable future. Forfeitures are estimated based on voluntary termination behavior, as well as a historical analysis of actual option forfeitures. The weighted-average assumptions used in the Black-Scholes option pricing model are as follows:
		Year Ended
		December 31,
		2013			2012			2011
	Expected stock price volatility		66	%		68	%		69	%
	Risk-free interest rate		0.87	%		0.8	%		1.12	%
	Expected life of options (in years)		4.5			4.8			4.7
	Expected dividend yield		0	%		0	%		0	%
	The weighted-average fair value (as of the date of grant) of the options granted during the year ended December 31, 2013, 2012 and 2011 was $15.79, $13.47 and $17.04, respectively. During the years ended December 31, 2013, 2012 and 2011, the Company recorded total pre-tax stock-based compensation expense of $25.2 million ($16.8 million after tax or $0.42 per diluted share), $20.4 million ($12.9 million after tax or $0.33 per diluted share), and $22.1 million ($14.1 million after tax or $0.37 per diluted share), respectively, which includes the fair value for equity awards issued after January 1, 2006. The total stock-based compensation cost related to non-vested equity awards not yet recognized as an expense as of December 31, 2013 was approximately $40.3 million. That cost is expected to be recognized over a weighted-average period of approximately 2.41 years.

Employee Stock Purchase Plan
On February 1, 2012, the Company established a ten year Employee Stock Purchase Plan ("ESPP" or "the Plan") for certain eligible employees. The Plan is to be administered by the Company's Board of Directors. The total number of shares available for purchase under the Plan is 500 shares of the Company's Common Stock. Employees participate over a six month period through payroll withholdings and may purchase, at the end of the six month period, the Company's Common Stock at the lower of 85% of the fair market value on the first day of the offering period or the fair market value on the purchase date. No participant will be granted a right to purchase Common Stock under the Plan if such participant would own more than 5% of the total combined voting power of the Company. In addition, no participant may purchase more than a thousand shares of Common Stock within any purchase period.
The expected life of ESPP shares is the average of the remaining purchase period under each offering period. The weighted-average assumptions used to value employee stock purchase rights during December 31, 2013 were as follows:
	Year Ended
	December 31,
	2013			2012
Expected stock price volatility		65	%		68	%
Risk-free interest rate		1.04	%		0.92	%
Expected life of ESPP shares (in years)		0.5			0.5
Expected dividend yield		0	%		0	%
During the years ended December 31, 2013 and 2012, the Company recorded $640 and $457, respectively, of compensation expense related to the ESPP. During the years ended December 31, 2013 and 2012, the Company sold a total of 66 and 33 shares, respectively, of its Treasury Stock pursuant to purchases under its ESPP Plan. Cash received from purchases through the ESPP Plan during the years ended December 31, 2013 and 2012, was approximately $1.5 million and $612, respectively, and is included within the financing activities section of the consolidated statements of cash flows. There were no shares purchased during the year ending December 31, 2011. The total unrecognized compensation expense related to the ESPP as of December 31, 2013 was approximately $44, which is expected to be recognized over the remainder of the offering period.
Treasury Stock
On May 8, 2012, the Company's Board of Directors authorized a stock repurchase program to purchase up to $25 million of the Company's outstanding Common Stock. The duration of the repurchase program is twelve months. Under the program, the Company may purchase shares of its Common Stock in the open market, through block trades or otherwise at prices deemed appropriate by the Company. The timing and amount of repurchase transactions under the program will depend on available working capital. As of December 31, 2012, a total of 1.2 million shares were purchased under the program for an aggregate purchase price of $24.6 million. The Company classifies Common Stock repurchased as Treasury Stock on its balance sheet. There were no repurchases of Common Stock under the stock repurchase program for the year ended December 31, 2013.

At December 31, 2013, the Company had approximately $60.2 million of federal net operating losses, approximately $51.0 million of state net operating losses, and approximately $48.3 million of foreign net operating losses. These federal and state net operating loss carryforwards begin to expire in 2014 and are subject to certain limitations under Internal Revenue Code Section 382 due to the changes in ownership of the acquired companies. The foreign net operating losses generally do not expire.
In January 2013, the Income Tax Department of India closed the 2009 income tax examination of the Company's wholly-owned subsidiary, Synchronoss Technologies India, without changes. Examinations of 2010 and 2011 are in progress. The Company believes the result of these audits will not have a material effect on its financial position or results of operations.
The Company is currently under income tax examinations in several states but does not believe that the results of these audits will have a material effect on its financial position or results of operations
The Company has not provided taxes for undistributed earnings of its foreign subsidiaries except to the extent that the Company does not plan to reinvest such earnings indefinitely outside the United States. If the cumulative foreign earnings exceed the amount the Company intends to reinvest in foreign countries in the future, the Company would provide for taxes on such excess amount. The undistributed earnings of the foreign subsidiaries, which the Company plans to reinvest indefinitely outside the United States, are approximately $26.8 million.

In December 2013, Eurowebfund and Bakamar, two former shareholders of Miyowa SA filed a complaint against the Company in the Commercial Court of Paris, France claiming that they are entitled to certain earn-out payments under the acquisition agreement. The Company was served with a copy of this complaint in January 2014. The Company believes Miyowa SA failed to meet the criteria required for it to pay the claimed amounts and that no earn-out payments are owed. Although the Company cannot predict the outcome of the lawsuit due to the inherent uncertainties of litigation, it believes the positions of Eurowebfund and Bakamar are without merit, and the Company intends to vigorously defend against all claims brought by them.
	The Company is not currently subject to any legal proceedings that could have a material adverse effect on its operations; however, it may from time to time become a party to various legal proceedings arising in the ordinary course of its business. The Company is currently the plaintiff in several patent infringement cases. The defendants in several of these cases have filed counterclaims.

Basis of Presentation and Consolidation	'
	Basis of Presentation and Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and accounts are eliminated in consolidation.
	Certain amounts from the prior year balance sheet have been recasted. In connection with the Spatial Systems Nominees PTY LTD ("Spatial") acquisition, the consolidated balance sheet at December 31, 2012 has been recast to include retrospective purchase accounting adjustments. These adjustments pertain to measurement period adjustments during the period ended November 30, 2013, based on the reclassification and valuation of assets acquired and liabilities assumed in the Spatial acquisition. The effect on the consolidated balance sheet at December 31, 2012, as a result of the recast, is a decrease in accounts receivable of $2.6 million, an increase in prepaid expenses and other assets of $5.0 million, an increase in goodwill of $11.8 million, an increase in accrued expenses of $4.6 million, and an increase in deferred revenues of $9.6 million.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Revenue Recognition and Deferred Revenue	'
	Revenue Recognition and Deferred Revenue
	The Company provides services principally on a transactional or subscription basis or, at times, on a fixed fee basis and recognizes the revenues as the services are performed or delivered as described below:
	Transactional and Subscription Service Arrangements:    Transaction and subscription revenues represented approximately 70%, 67%, and 77% of revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Transaction and subscription revenues consist of revenues derived from the processing of transactions through the Company's service platforms, providing enterprise portal management services on a subscription basis and maintenance agreements on software licenses. Transaction service arrangements include services such as processing equipment orders, new account set-up and activation, number port requests, credit checks and inventory management. Subscription services include hosting and storage and the related maintenance support for those services.
	Transaction revenues are principally based on a contractual price per transaction and are recognized based on the number of transactions processed during each reporting period. Revenues are recorded based on the total number of transactions processed at the applicable price established in the relevant contract. The total amount of revenues recognized is based primarily on the volume of transactions. Subscription revenues are recorded on a straight-line basis over the life of the contract for subscription services and maintenance agreements.
	Many of the Company's contracts guarantee minimum volume transactions from the customer. In these instances, if the customer's total transaction volume for the period is less than the contractual amount, the Company records revenues at the minimum guaranteed amount. At times, transaction revenues may also include billings to customers that reimburse the Company based on the number of individuals dedicated to processing transactions. Set-up fees for transactional service arrangements are deferred and recognized on a straight-line basis over the life of the contract since these amounts would not have been paid by the customer without the related transactional service arrangement. Revenues are presented net of discounts, which are volume level driven, or credits, which are performance driven, and are determined in the period in which the volume thresholds are met or the services are provided.
	Professional Service and Software License Arrangements:    Professional service and software license revenues represented approximately 30%, 33% and 23% of revenues for the years ended December 31, 2013, 2012 and 2011, respectively. Professional services include process and workflow consulting services and development services. Professional services, when sold with non-software transactional or subscription service arrangements, are accounted for separately when the professional services have value to the customer on a standalone basis. Professional services, when sold with software transactional or subscription service arrangements are accounted for separately when the professional services have value to the customer on a standalone basis and there is objective and reliable evidence of fair value of the professional services. When accounted for separately, professional service revenues are recognized on a monthly basis, as services are performed and all other elements of revenue recognition have been satisfied.
	In determining whether professional service revenues can be accounted for separately from transaction or subscription service revenues, the Company considers the following factors for each professional services agreement: availability of the professional services from other vendors, whether objective and reliable evidence of fair value exists of the undelivered elements, the nature of the professional services, the timing of when the professional services contract was signed in comparison to the transaction or subscription service start date and the contractual independence of the transactional or subscription service from the professional services.
	If a professional service arrangement were not to qualify for separate accounting, the Company would recognize the professional service revenues ratably over the remaining term of the transaction or subscription agreement.
	Revenue from software license arrangements is recognized when the license is delivered to its customers and all of the software revenue recognition criteria are met. When software arrangements include multiple elements, the arrangement consideration is allocated at the inception to all deliverables using the residual method providing the Company has vendor specific objective evidence (VSOE) on all undelivered elements. The Company determines VSOE for each element based on historical stand-alone sales to third parties. When sold with non-software transaction or subscription service arrangements, the arrangement consideration is allocated at the inception of an arrangement to all deliverables using the relative selling price method. The relative selling price method allocates any discount in the arrangement proportionally to each deliverable on the basis of each deliverable's selling price. The selling price used for each deliverable will be based on VSOE if available, third-party evidence (TPE) if vendor-specific objective evidence is not available, or estimated selling price (ESP) if neither vendor-specific objective evidence nor third-party evidence is available. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The Company determines ESP by considering multiple factors, including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives, and pricing practices. ESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.
	While the Company follows specific and detailed rules and guidelines related to revenue recognition, it makes and uses management judgments and estimates in connection with the revenue recognized in any reporting period, particularly in the areas described above, as well as collectability. If management made different estimates or judgments, differences in the timing of the recognition of revenue could occur.
	Deferred Revenue:    Deferred revenues primarily represent billings to customers for services in advance of the performance of services, with revenues recognized as the services are rendered, and also includes the fair value of deferred revenues recorded as a result of acquisitions.
Service Level Standards	'
	Service Level Standards
	Pursuant to certain contracts, the Company is subject to service level standards and to corresponding penalties for failure to meet those standards. All performance-related penalties are reflected as a corresponding reduction of the Company's revenues. These penalties, if applicable, are recorded in the month incurred and were insignificant for the years ended December 31, 2013, 2012 and 2011, respectively.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	The Company's financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable. The Company maintains its cash and cash equivalents at several major financial institutions. The Company has not experienced any realized losses in such accounts and believes it is not exposed to any significant credit risk related to cash, cash equivalents and securities. The Company's cash equivalents and short-term marketable securities consist primarily of money market funds, certificates of deposit, and municipal and corporate bonds. The Company believes that concentration of credit risk with respect to accounts receivable is limited because of the creditworthiness of the Company's major customers.
	The Company's top five customers accounted for 77%, 76% and 86% of net revenues for 2013, 2012 and 2011, respectively. The Company's top five customers accounted for 76% and 67% of accounts receivable at December 31, 2013 and 2012, respectively. Of these customers, AT&T and Verizon Wireless each accounted for more than 10% of the Company's revenues in 2013. The loss of either AT&T or Verizon as a customer would have a material negative impact on the Company. The Company believes that if either AT&T or Verizon terminated their relationships with Synchronoss, AT&T and Verizon would encounter substantial costs in replacing Synchronoss' transaction management solutions.
Fair Value of Financial Instruments and Liabilities	'
	Fair Value of Financial Instruments and Liabilities
	The Company includes disclosures of fair value information about financial instruments and liabilities, whether or not recognized on the balance sheet, for which it is practicable to estimate that value. Due to their short-term nature, the carrying amounts reported in the financial statements approximate the fair value for cash and cash equivalents, marketable securities, accounts receivable and accounts payable.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company considers all highly liquid investments purchased with a maturity of three months or less at the date of acquisition to be cash equivalents.
Marketable Securities	'
	Marketable Securities
	Marketable securities consist of fixed income investments with a maturity of greater than three months and enhanced money market funds. These investments are classified as available-for-sale and are reported at fair value on the Company's balance sheet. The Company classifies its securities with maturity dates of 12 months or more as long term. Unrealized holding gains and losses are reported within accumulated other comprehensive loss as a separate component of stockholders' equity. If a decline in the fair value of a marketable security below the Company's cost basis is determined to be other than temporary, such marketable security is written down to its estimated fair value as a new cost basis and the amount of the write-down is included in earnings as an impairment charge. The Company has recorded temporary changes in fair value of the marketable securities but has not recorded other-than-temporary charges for the periods presented herein.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable consist of amounts due to the Company from normal business activities. The Company maintains an allowance for estimated losses resulting from the inability of its customers to make required payments. The Company estimates uncollectible amounts based upon historical bad debts, current customer receivable balances, the age of customer receivable balances, the customer's financial condition and current economic trends.
Property and Equipment	'
	Property and Equipment
	Property and equipment and leasehold improvements are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 5 years, or the lesser of the related initial term of the lease or useful life for leasehold improvements. Amortization of property and equipment recorded under a capital lease is included with depreciation expense. Expenditures for routine maintenance and repairs are charged against operations. Major replacements, improvements and additions are capitalized.
Business Combinations	'
	Business Combinations
	The Company accounts for business combinations in accordance with the acquisition method. The acquisition method of accounting requires that assets acquired and liabilities assumed be recorded at their fair values on the date of a business acquisition. The Company's consolidated financial statements and results of operations reflect an acquired business from the completion date of an acquisition.
	The judgments that the Company makes in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact net income in periods following a business combination. The Company generally uses either the income, cost or market approach to aid in its conclusions of such fair values and asset lives. The income approach presumes that the value of an asset can be estimated by the net economic benefit to be received over the life of the asset, discounted to present value. The cost approach presumes that an investor would pay no more for an asset than its replacement or reproduction cost. The market approach estimates value based on what other participants in the market have paid for reasonably similar assets. Although each valuation approach is considered in valuing the assets acquired, the approach ultimately selected is based on the characteristics of the asset and the availability of information.
	The Company records contingent consideration resulting from a business combination at its fair value on the acquisition date. Each reporting period thereafter, the Company revalues these obligations and records increases or decreases in their fair value as an adjustment to net change in contingent consideration obligation within the consolidated statement of income. Changes in the fair value of the contingent consideration obligation can result from updates in the achievement of financial targets and changes to the weighted probability of achieving those future financial targets. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, any change in the assumptions described above, could have a material impact on the amount of the net change in contingent consideration obligation that the Company records in any given period.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	Goodwill represents the excess of the purchase price over the fair value of assets acquired, including other definite-lived intangible assets. Goodwill is not amortized, but reviewed annually for impairment or upon the occurrence of events or changes in circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount. There were no impairment charges recognized during the years ended December 31, 2013, 2012 and 2011.
	Intangible assets that do not have indefinite lives (primarily technology and customer relationships) are amortized over their useful lives. All of intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reevaluates the useful life determinations for these intangible assets each year to determine whether events and circumstances warrant a revision in their remaining useful lives.
Impairment of Long-Lived Assets	'

	A review of long-lived assets for impairment is performed when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If an indication of impairment is present, the Company compares the estimated undiscounted future cash flows to be generated by the asset to the asset's carrying amount. If the undiscounted future cash flows are less than the carrying amount of the asset, the Company records an impairment loss equal to the amount by which the asset's carrying amount exceeds its fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. There were no impairment charges recognized during the years ended December 31, 2013, 2012 and 2011.
Cost of Services	'
	Cost of Services
	Cost of services includes all direct materials, direct labor and those indirect costs related to revenues such as indirect labor, materials and supplies and facilities cost, exclusive of depreciation expense.
Research and Development	'
	Research and Development
	Research and development costs are expensed as incurred, unless they meet U.S. GAAP criteria for deferral and amortization. Software development costs incurred prior to the establishment of technological feasibility do not meet these criteria, and are expensed as incurred. Amortization of software development costs is computed using the straight-line method over the estimated useful lives of the assets, 3 and 5 years. As of December 31, 2013, the Company had $1.8 million of unamortized software development costs and $1.2 million of amortization expense which was recognized during 2013. As of December 31, 2012, the Company had $2.0 million of unamortized software development costs and $1.3 million of amortization expense which was recognized during 2012. Research and development expense consists primarily of costs related to personnel, including salaries and other personnel-related expenses, consulting fees and the cost of facilities, computer and support services used in service technology development. The Company also expenses costs relating to developing modifications and minor enhancements of its existing technology and services.
Income Taxes	'
	Income Taxes
	Since the Company conducts operations on a global basis, its effective tax rate has and will depend upon the geographic distribution of its pre-tax earnings among locations with varying tax rates. The Company accounts for the effects of income taxes that result from its activities during the current and preceding years. Under this method, deferred income tax liabilities and assets are based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse or be utilized. The realization of deferred tax assets is contingent upon the generation of future taxable income. A valuation allowance is recorded if it is "more likely than not" that a portion or all of a deferred tax asset will not be realized.
	The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The amount of the accrual for which an exposure exists is measured by determining the amount that has a greater than 50 percent likelihood of being realized upon the settlement of the position. Components of the reserve are classified as a long-term liability in the consolidated balance sheets. The Company records interest and penalties accrued in relation to uncertain tax benefits as a component of interest expense. The Company expects that the amount of unrecognized tax benefits will change during 2014; however, the Company does not expect the change to have a significant impact on its results of operations or financial position.
	While the Company believes it has identified all reasonably identifiable exposures and that the reserve that the Company has established for identifiable exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures may be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause the Company to either materially increase or reduce the carrying amount of its tax reserves. In general, tax returns for the year 2010 and thereafter are subject to future examination by tax authorities.
	The Company's policy has been to leave its cumulative unremitted foreign earnings invested indefinitely outside the United States, and the Company intends to continue this policy. As such, taxes have not been provided on any of the remaining accumulated foreign unremitted earnings. If the cumulative unremitted foreign earnings exceed the amount the Company intends to reinvest in foreign countries in the future, the Company would provide for taxes on such excess amount.
Foreign Currency	'
	Foreign Currency
	Prior to the third quarter of 2013, several of the Company's subsidiaries that operate outside the U.S. used the U.S. dollar as the functional currency. Effective July 1, 2013, the Company changed the functional currencies of those subsidiaries that operate outside the U.S. to their local currency. This change was the result of a change in the Company's international operations and economic strategies driven by the implementation of a global financial system that has allowed the Company's foreign operations to become self-contained and integrated within their resident countries and to the local currency.
	The functional currency is translated into U.S. dollars for balance sheet accounts using the month end rates in effect as of the balance sheet date and average exchange rate for revenue and expense accounts for each respective period. The translation adjustments are deferred as a separate component of stockholders' equity, within accumulated other comprehensive income. Gains or losses resulting from transactions denominated in foreign currencies are included in other income or expense, within the consolidated statements of income. The effects of the change in functional currency were not material to the Company's consolidated financial statements for all years presented.
Comprehensive Income	'
	Comprehensive Income
	Reporting on comprehensive income requires components of other comprehensive income, including unrealized gains or losses on available-for-sale securities, to be included as part of total comprehensive income. Comprehensive income is comprised of net income, translation adjustments and unrealized gains and losses on available-for-sale securities. The components of comprehensive income are included in the statements of comprehensive income.
Basic and Diluted Net Income Attributable to Common Stockholders per Common Share	'
	Basic and Diluted Net Income Attributable to Common Stockholders per Common Share
	The Company calculates basic and diluted per share amounts based on net earnings adjusted for the effects to earnings that would result if contingently issuable shares related to contingent consideration to be settled in the Company's stock were reported as equity for the periods presented. Basic earnings per share is calculated by using the weighted average number of common shares outstanding during the period. The diluted earnings per share calculation is based on the weighted average number of shares of common stock outstanding adjusted for the number of additional shares that would have been outstanding had all potentially dilutive common shares been issued. Potentially dilutive shares of common stock include stock options, non-vested share awards and contingently issuable shares related to contingent consideration to be settled in stock. The dilutive effects of stock options and restricted stock awards are based on the treasury stock method. The dilutive effects of the contingent consideration to be settled in stock are calculated as if the contingently issuable shares were outstanding as of the beginning of the period. The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income attributable to common stockholders per common share. Stock options that are anti-dilutive and excluded from the following table totaled 1,367, 1,840, and 947 for the years ended December 31, 2013, 2012 and 2011, respectively.

Stock-Based Compensation	'
	Stock-Based Compensation
	As of December 31, 2013, the Company maintains three stock-based compensation plans. The Company utilizes the Black-Scholes pricing model to determine the fair value of stock options on the dates of grant. Restricted stock awards are measured based on the fair market values of the underlying stock on the dates of grant, unless the awards are subject to market conditions, in which case the Company uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved. The Company recognizes stock-based compensation over the requisite service period with an offsetting credit to additional paid-in capital.
	For the Company's performance restricted stock awards the Company estimates the number of shares the recipient is to receive by applying a probability of achieving the performance goals. The actual number of shares the recipient receives is determined at the end of the annual performance period based on the results achieved versus goals based on its annual performance targets, such as operating income. Once the number of awards is determined, the compensation cost is fixed and continues to be recognized using the accelerated attribution recognition over the requisite service period for each vesting tranche.
	The Company classifies benefits of tax deductions in excess of the compensation cost recognized (excess tax benefits) as a financing cash inflow with a corresponding operating cash outflow. The Company included $3.0 million, $6.9 million and $3.6 million of excess tax benefits as a financing cash inflow for the years ended December 31, 2013, 2012 and 2011, respectively.
Impact of Recently Issued Accounting Standards	'
	Impact of Recently Issued Accounting Standards
	In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-02 which requires additional disclosures regarding the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 requires an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. This guidance is effective for reporting periods beginning after December 15, 2012. The Company adopted this guidance effective January 1, 2013. The Company's adoption of this standard did not have a significant impact on its consolidated financial statements.
	In March 2013, the FASB issued ASU 2013-05, which permits an entity to release cumulative translation adjustments into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided, or, if a controlling financial interest is no longer held. The revised standard is effective for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, which provides that a liability related to an unrecognized tax benefit would be offset against a deferred tax asset instead of presented gross for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. This new guidance is effective for fiscal years beginning after December 15, 2013. The Company does not expect adoption of this ASU to significantly impact its consolidated financial statements.
Segment and Geographic Information	'
	Segment and Geographic Information
	The Company's chief operating decision-maker is the Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources. Accordingly, the Company has determined that it currently operates in one business segment: providing cloud solutions and software-based activation for connected devices globally. The Company is not organized by market and is managed and operated as one business. A single management team reports to the chief operating decision maker who comprehensively manages the entire business. The Company does not operate any separate lines of business or separate business entities with respect to its services. Accordingly, the Company does not accumulate a complete set of discrete financial information with respect to separate service lines and does not have separately reportable segments. Although, the Company operates in North America, Europe and Asia-Pacific a majority of the Company's revenue and long lived assets are in the U.S.
	Revenues by geography are based on the billing addresses of the Company's customers. The following tables set forth revenues and property and equipment, net by geographic area:
