(1)	Basis of Presentation and Significant Accounting Policies

Nature of Operations

Merge Healthcare Incorporated and its subsidiaries or affiliates (collectively Merge, we, us, or our) is an enterprise image provider dedicated to healthcare information technology (IT) solutions. We develop software solutions that facilitate the sharing of images to create a more effective and efficient electronic healthcare experience for patients and physicians. Our solutions are designed to help solve some of the most difficult challenges in health information exchange today, such as the incorporation of medical images and diagnostic information into broader healthcare IT applications, the interoperability of proprietary software solutions, the profitability of outpatient imaging practices in the face of declining reimbursement and the ability to improve the efficiency and cost effectiveness of our customers' businesses.

Principles of Consolidation

The consolidated financial statements include the financial statements of our wholly owned subsidiaries, and include the results of all acquisitions from the dates of acquisition. All intercompany balances and transactions have been eliminated in consolidation.

We have certain minority equity interests in various companies accounted for as cost method investments. The operating results of these companies are not included in our results of operations. We also own a 63% equity interest in a company which is included in our consolidated financial statements. These statements are adjusted based on the noncontrolling interest's share.

Use of Estimates

Our consolidated financial statements are prepared in accordance with United States of America (U.S.) generally accepted accounting principles (GAAP). These accounting principles require us to make certain estimates, judgments 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. Estimates are used when accounting for items and matters such as revenue recognition and allowances for uncollectible accounts receivable and sales returns, inventory obsolescence, depreciation and amortization, long-lived and intangible asset valuations, impairment assessments, restructuring reserves, taxes and related valuation allowance, income tax provisions, stock-based compensation, and contingencies. We believe that the estimates, judgments and assumptions are reasonable, based on information available at the time they are made. Actual results may differ from those estimates.

Functional Currency

Certain of our foreign subsidiaries use the United States of America dollar (U.S. Dollar) as their functional currency. Foreign currency denominated revenues and expenses are translated at weighted average exchange rates throughout the year and foreign currency denominated monetary assets and liabilities are translated at rates prevailing at the balance sheet dates. For those foreign subsidiaries which use the U.S. Dollar as their functional currency, adjustments arising from the use of differing exchange rates from period to period are reflected in our consolidated statements of operations as a component of other income (expense), net. For those foreign subsidiaries which use their local currency as the functional currency, translation adjustments arising from the use of differing exchange rates from period to period are included as a component of other comprehensive income (loss). Foreign exchange gains and losses on transactions during the year are reflected in the consolidated statements of operations, as a component of other income (expense), net.

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, accounts receivable, marketable and non-marketable equity securities, accounts payable, notes payable, and certain accrued liabilities. The carrying amounts of these assets and liabilities approximate fair value due to the short maturity of these instruments, except for the notes payable and non-marketable equity securities. The carrying amount of the notes payable approximates fair value due to the interest rate and terms approximating those available to us for similar obligations. The estimated fair values of the non-marketable equity securities have been determined from information obtained from independent valuations and management estimates.

We use a three-tier value hierarchy to prioritize the inputs used in measuring fair value of our financial assets and liabilities. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore, requiring an entity to develop its own assumptions.

We also consider additional information in estimating fair value when the volume and level of activity for the asset or liability have significantly decreased, or circumstances indicate a transaction is not suitable for fair value measurement. See Note 5 for further discussion of the fair value of our financial instruments.

Cash and Cash Equivalents

Cash and cash equivalents consist of balances with banks (including restricted cash), money market accounts and liquid short-term investments with original maturities of ninety days or less and are carried on the balance sheet at cost plus accrued interest. As of December 31, 2012, cash and cash equivalents were $35,875, including restricted cash of $813. Restricted cash consisted of letters-of-credit relating to our leased facilities.

Inventory

Inventory, consisting principally of finished goods (primarily purchased third-party hardware) is stated at the lower of cost or market determined on a first-in, first-out (FIFO) basis. We also maintain inventory reserves for excess and obsolete inventory determined based on the age of our inventory.

Other Current Assets

Other current assets consist primarily of revenue recognized that has not yet been billed to a customer, unbilled A/R from acquisitions, an equity investment and other non-trade receivables, all of which are due within the next twelve months.

The balances are comprised of the following as of December 31, 2012 and 2011:

	December 31,
	2012		2011
Revenue recognized in excess of billings, net of reserves of $1,763 and $235, respectively	$	18,812	$	18,064
Acquired unbilled A/R		350		1,769
Equity investment		2,016		-
Other non-trade receivables		443		366
	$	21,621	$	20,199

The following table shows the changes in our reserves for revenue recognized in excess of billings:

	Balance at Beginning of Period		Net Additions Charged to Revenue and Expenses		Deductions		Balance at End of Period
For year ended December 31,:
2012	$	235	$	1,528	$	-	$	1,763
2011	$	-	$	235	$	-	$	235

During the fourth quarter of 2012, we recorded a charge of $1,308 related primarily to uncollectible billings from customer contracts obtained through acquisitions in the past few years. The $1,308 related to a change in estimate to our reserve for revenues in excess of billings. The effect of the change in estimate related to our reserve for revenues in excess of billings, which was recorded to general and administrative in our statement of operations, was to increase our net loss by $1,308 ($0.01 per share, net of income tax), for the year ended December 31, 2012.

Property and Equipment

Property and equipment are stated at cost. Depreciation on property and equipment is calculated on the straight-line method over the estimated useful lives of the assets. Property and equipment are evaluated for potential impairment whenever events or circumstances indicate that the carrying amount may not be recoverable, based primarily upon whether expected future undiscounted cash flows are sufficient to support the asset's recovery. Useful lives of our major classes of property and equipment are three years for computer equipment and three to five years for office equipment. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated life of the asset or the term of the lease. We recorded depreciation expense of $3,752, $3,955 and $4,091 in 2012, 2011 and 2010, respectively.

Intangible Assets and Goodwill

Intangible assets include purchased and capitalized technology, customer relationships, backlog, trade names, and non-compete agreements. Finite-lived intangible assets are amortized to reflect the pattern of economic benefits consumed, which is primarily the straight-line method.

Purchased software and capitalized software are tested for impairment quarterly by comparing the net realizable value (estimated using undiscounted future cash flows) to the carrying value of the software. If the carrying value of the software exceeds its net realizable value, we record an impairment charge in the period in which the impairment is incurred equal to the amount of the difference between the carrying value and estimated undiscounted future cash flows.

Customer relationships, backlog, trade names and non-compete agreements are evaluated for potential impairment whenever events or circumstances indicate that the carrying amount may not be recoverable, based primarily upon whether expected future undiscounted cash flows are sufficient to support the asset's recovery. If the actual useful life of the asset is shorter than the useful life estimated by us, the asset may be deemed to be impaired, and, accordingly, a write-down of the value of the asset determined by a discounted cash flow analysis, or a shorter amortization period, may be required. We have reviewed these assets with estimable useful lives and determined that their carrying values as of December 31, 2012 are recoverable in future periods.

All research and development costs incurred prior to the point at which management believes a project has reached technological feasibility or incurred in the preliminary stages of development are expensed as incurred.

We review goodwill for impairment annually on October 1st, or more frequently if impairment indicators arise. During 2012, our reporting units changed from Merge Healthcare and Merge eClinical to Merge Healthcare and Merge Data and Analytics (DNA) due to the level of discrete financial information as well as the aggregation of Merge's components, which exhibit similar long term performance and have similar economic characteristics. In calculating potential impairment losses, we evaluate the fair value of goodwill using either quoted market prices or, if not available, by estimating the expected present value of their future cash flows. Identification of, and assignment of assets and liabilities to, a reporting unit require our judgment and estimates. In addition, future cash flows are based upon our assumptions about future sales activity and market acceptance of our products. We performed our annual goodwill testing and determined that there is no impairment, since the fair value of our reporting units substantially exceeded the carrying value.

Other Current Liabilities

Other current liabilities consist primarily of customer deposits, the current portion of an acquisition obligation, accrued taxes, lease line facility, leases payable,and other non-trade payables, all of which are due within the next twelve months.

The balances are comprised of the following as of December 31, 2012 and 2011:

	December 31,
	2012		2011
Customer deposits	$	3,409	$	2,469
Acquisition obligation		2,815		4,651
Accrued taxes		998		782
Lease line facility		897		-
Leases payable		83		473
Other liabilities		4,404		3,205
	$	12,606	$	11,580

The acquisition obligation relates to the current portion of the balance due for an insignificant acquisition completed in 2011. The non-current portion of $2,041 and $4,558 is recorded in other non-current liabilities in our consolidated balance sheets as of December 31, 2012 and 2011, respectively. Total amounts to be paid under this obligation of $2,815, $1,967 and $273 in 2013, 2014 and 2015, respectively, were recorded at their discounted amounts based on the payment due dates.

Guarantees

We recognize the fair value of guarantee and indemnification arrangements issued or modified by us, as applicable. In addition, we must continue to monitor the conditions that are subject to the guarantees and indemnifications in order to identify if a loss has occurred. If we determine it is probable that a loss has occurred, then any such estimable loss would be recorded under those guarantees and indemnifications.

Under our standard software license agreements, we agree to indemnify, defend and hold harmless our licensees from and against certain losses, damages and costs arising from claims alleging the licensees' use of our software infringes the intellectual property rights of a third party. Historically, we have not been required to pay material amounts in connection with claims asserted under these provisions, and, accordingly, we have not recorded a liability relating to such provisions. We also represent and warrant to licensees that our software products will operate substantially in accordance with published specifications, and that the services we perform will be undertaken by qualified personnel in a professional manner conforming to generally accepted industry standards and practices. Historically, only minimal costs have been incurred relating to the satisfaction of product warranty claims.

Other guarantees include promises to indemnify, defend and hold harmless each of our executive officers, non-employee directors and certain key employees from and against losses, damages and costs incurred by each such individual in administrative, legal or investigative proceedings arising from alleged wrongdoing by the individual while acting in good faith within the scope of his or her job duties on our behalf.

Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate income taxes in each of the jurisdictions in which we operate. Our provision for income taxes is determined using the asset and liability approach to account for income taxes. A current liability is recorded for the estimated taxes payable for the current year. Deferred tax assets and liabilities are recorded for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates in effect for the year in which the timing differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of changes in tax rates or tax laws are recognized in the provision for income taxes in the period that includes the enactment date.

Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount more-likely-than-not to be realized. Changes in valuation allowances will flow through the statement of operations unless related to deferred tax assets that expire unutilized or are modified through translation, in which case both the deferred tax asset and related valuation allowance are similarly adjusted. Where a valuation allowance was established through purchase accounting for acquired deferred tax assets, any future change will be credited or charged to income tax expense.

The determination of our provision for income taxes requires significant judgment, the use of estimates, and the interpretation and application of complex tax laws. We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes and recording the related tax assets and liabilities. In the ordinary course of our business, there are transactions and calculations for which the ultimate tax determination is uncertain. In spite of our belief that we have appropriate support for all the positions taken on our tax returns, we acknowledge that certain positions may be successfully challenged by the taxing authorities. We determine the tax benefits more likely than not to be recognized with respect to uncertain tax positions. Unrecognized tax benefits are evaluated quarterly and adjusted based upon new information, resolution with taxing authorities and expiration of the statute of limitations. The provision for income taxes includes the impact of changes in the liability for our uncertain tax positions. Although we believe our recorded tax assets and liabilities are reasonable, tax laws and regulations are subject to interpretation and inherent uncertainty; therefore, our assessments can involve both a series of complex judgments about future events and rely on estimates and assumptions. Although we believe these estimates and assumptions are reasonable, the final determination could be materially different than that which is reflected in our provision for income taxes and recorded tax assets and liabilities.

Accumulated Other Comprehensive Income

Foreign currency translation adjustments and unrealized gains or losses on our available-for-sale securities, net of applicable taxes, are included in accumulated other comprehensive income, and are further detailed in Note 5 for the years ended December 31, 2012 and 2011.

Revenue Recognition

Revenues are derived primarily from the licensing of software, sales of hardware and related ancillary products, hosted clinical trial software-as-a-service (SaaS) offerings, installation and engineering services, training, consulting, and software maintenance and support. Inherent to software revenue recognition are significant management estimates and judgments in the interpretation and practical application of the complex rules to individual contracts. These interpretations generally would not influence the amount of revenue recognized, but could influence the timing of such revenues. Typically, our contracts contain multiple elements, and while the majority of our contracts contain standard terms and conditions, there are instances where our contracts contain non-standard terms and conditions. As a result, contract interpretation is sometimes required to determine the appropriate accounting, including whether the deliverables specified in a multiple-element arrangement should be treated as separate units of accounting for revenue recognition purposes, and if so, the relative selling price that should be allocated to each of the elements and when to recognize revenue for each element.

We recognize revenue on software arrangements involving multiple elements, including separate arrangements with the same customer executed within a short time frame of each other, based on the vendor-specific objective evidence (VSOE) of fair values of those elements. For the majority of our business, we determine the fair value of the maintenance and support portion of the arrangement based on the substantive renewal price of the maintenance offered to customers, which generally is stated in the contract. The fair value of installation, engineering services, training, and consulting is based upon the price charged when these services are sold separately. For sales transactions where the software is incidental or the only contract deliverable is engineering or other services, as well as hardware transactions where no software is involved, we recognize revenue based on VSOE of fair value, other third-party evidence of fair value or our best estimated selling price of those elements.

Revenue from multiple-element arrangements including software is recognized using the residual method. Under the residual method, revenue is recognized in a multiple element arrangement when fair value exists for all of the undelivered elements in the arrangement, even if fair value does not exist for one or more of the delivered elements in the arrangement, assuming all other conditions for revenue recognition have been satisfied. If evidence of fair value cannot be established for the maintenance and support element of a sale, and it represents the only undelivered element, all contract elements are deferred and recognized ratably over the related maintenance and support period.

Revenue from multiple-element arrangements not including software is typically recognized using the relative method. Under the relative method, revenue is recognized in a multiple element arrangement based on selling prices for all of the elements in the arrangement, assuming all other conditions for revenue recognition have been satisfied.

Provided that evidence of an arrangement exists, fees are fixed or determinable, collection of the related receivable is probable, fair value for the undelivered elements exist and there are no other contract considerations resulting in the deferral of revenue, we typically recognize revenue in the following manner:

Software licenses and hardware are recognized upon delivery, while installation, engineering services, training, and consulting services are recognized as performed and maintenance and support is recognized ratably over the period in which the services are performed. This is the primary method used for sales of software products which are typically fully functional upon delivery and do not require significant modification or alteration. Any subsequent software royalties associated with such contracts are generally recognized as reported by the customer. Revenue is also recognized in this manner for the majority of sales of additional modules to existing customers.

Merge sells software with or without various standard hardware components (i.e. servers, monitors, storage disk arrays, etc.). The hardware items are sold primarily as a convenience for its customers who may choose not to purchase it because either they already have the applicable hardware or they purchased the hardware directly from a third party vendor. We have a sufficient number of stand-alone sales of hardware to allow it to obtain vendor-specific objective evidence of fair value for the hardware. These arrangements include software that is more-than-incidental to the hardware. Therefore, the software is not essential to the functionality of the hardware (and vice versa).

Software licenses sold through annual contracts that include software maintenance and support are deferred and recognized ratably over the one-year period.

Revenues derived from SaaS offerings are generally recognized ratably as we provide software application-hosting and are recognized using the proportional performance method for services provided to customers under fixed-price contracts. Such contracts are entered into by certain customers with clinical trial products comprising the vast majority. These contracts consist of master agreements containing general terms and conditions and separately negotiated addendums (called task orders) which include services, software subscription and usage fees, and hosting fees. Customers generally have the ability to terminate contracts upon 30 days notice. However, these contracts typically require payment of fees earned from all services provided through the termination date.

If services are considered essential to the functionality of the software, revenue is recognized based on service hours expended through project completion and maintenance and support is recognized ratably over the applicable period.

EDI revenues are typically recognized monthly based on transactional volumes or a fixed fee.

If services are considered essential, we recognize revenue using either the proportional performance guidelines or percentage of completion accounting, as appropriate. Revenue is determined by the input method based upon the amount of labor hours expended compared to the total labor hours expended plus the estimated amount of labor hours to complete the project. Total estimated labor hours are based on management's best estimate of the total amount of time it will take to complete a project. These estimates require the use of judgment. A significant change in one or more of these estimates could affect the profitability of one or more of our contracts. We review our contract estimates periodically to assess the possible need for revisions in contract values and estimated labor hours, and reflect changes in estimates in the period that such estimates are revised under the cumulative catch-up method. When estimates indicate a loss, such loss is recognized in the current period in its entirety. Because of the inherent uncertainties in estimating total labor hours, it is possible that the estimates will change and could result in a material change of revenue recognized in the applicable period. We record a loss for a contract at the point it is determined that the total estimated contract costs will exceed management's estimates of contract revenues. As of December 31, 2012, we have not experienced any material losses on uncompleted contracts.

We assess collectability based on a number of factors, including past transaction history with the customer and the credit worthiness of the customer. We must exercise our judgment when we assess the probability of collection and the current credit worthiness of each customer. We have provided for an allowance for estimated returns and credits based on our historical experience of returns and customer credits.

Deferred revenue is comprised of deferrals for license fees, support and maintenance and other services. Long-term deferred revenue as of December 31, 2012 represents license fees, support and maintenance and other services to be earned or provided beginning January 1, 2014. Revenue recognized that has not yet been billed to a customer results in an asset as of the end of the period. As of December 31, 2012 and 2011, there was $18,812 and $18,064 net of reserves recorded within other current assets related to revenue recognized that has not yet been billed.

We record reimbursable out-of-pocket expenses in both services and maintenance net sales and as a direct cost of services and maintenance. The reimbursement by customers of shipping and handling costs are recorded in software and other net sales and the associated cost as a cost of sale. Sales tax, if any, is passed on to our customers.

Share-Based Compensation

We calculate share-based compensation expense for option awards based on the estimated grant-date fair value using the Black-Scholes option pricing model, and recognize the expense on a straight-line basis over the vesting period, net of estimated forfeitures. We evaluate the assumptions used to value stock options and restricted stock awards on a quarterly basis. The estimation of share-based awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. We consider different factors when estimating expected forfeitures, including types of awards, employee class, and historical experience.

Recent Accounting Pronouncements

We describe below recent pronouncements that have had or may have a significant effect on our financial statements or have an effect on our disclosures. We do not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to our financial condition, statement of operations, or related disclosures.

In October 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2012-04, Technical Corrections and Improvements. The amendments in this update cover a wide range of Topics in the Accounting Standards Codification. These amendments include technical corrections and improvements to the Accounting Standards Codification and conforming amendments related to fair value measurements. The amendments in this update will be effective for fiscal periods beginning after December 15, 2012. The adoption of ASU No. 2012-014 did not have a material impact on our statement of operations, financial position or cash flows.

In August 2012, the FASB issued ASU No. 2012-03, Technical Amendments and Corrections to SEC Sections: Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 114, Technical Amendments Pursuant to SEC Release No. 33-9250, and Corrections Related to FASB Accounting Standards Update No. 2010-22 (SEC Update). This update amends various SEC paragraphs pursuant to the issuance of SAB No. 114. The adoption of ASU No. 2012-03 did not have a material impact on our statement of operations, financial position, or cash flows.

In July 2012, the FASB issued ASU No. 2012-02, Intangibles — Goodwill and Other — Testing Indefinite-Lived Intangible Assets for Impairment, to establish an optional two-step analysis for impairment testing of indefinite-lived intangibles other than goodwill. The two-step analysis establishes an optional qualitative assessment to precede the quantitative assessment, if necessary. In the qualitative assessment, the entity must evaluate the totality of qualitative factors, including any recent fair value measurements, that impact whether an indefinite-lived intangible asset other than goodwill has a carrying amount that more likely than not exceeds its fair value. The entity must proceed to conducting a quantitative analysis, according to which the entity would record an impairment charge for the amount of the asset's fair value exceeding the carrying amount, if (1) the entity determines that such an impairment is more likely than not to exist, or (2) the entity foregoes the qualitative assessment entirely. The standards update will be effective for financial statements of periods beginning after September 15, 2012, with early adoption permitted. The adoption of ASU No. 2012-02 is not expected to have a material impact on our statement of operations, financial position, or cash flows.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. This ASU permits a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value before applying the two-step goodwill impairment test. If an entity can support the conclusion that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not need to perform the two-step impairment test for that reporting unit. This ASU is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011. The adoption of ASU No. 2011-08 did not have a material impact on our statement of operations, financial position, or cash flows.

In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU No. 2011-05 amends the FASB Accounting Standards Codification (Codification) to allow an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In either case, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU No. 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments to the Codification in the ASU do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. We adopted ASU No. 2011-05 as of January 1, 2012, and it did not impact the presentation of comprehensive income in our consolidated condensed financial statements.

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements. This ASU represents the converged guidance of the FASB and the International Accounting Standards Board (the Boards) on fair value measurement. The collective efforts of the Boards and their staffs, reflected in ASU No. 2011-04, have resulted in common requirements for measuring fair value and for disclosing information about fair value measurements, including a consistent meaning of the term "fair value." The Boards have concluded the common requirements will result in greater comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and International Financial Reporting Standards. The amendments to this ASU are to be applied prospectively. ASU No. 2011-04 is effective during interim and annual periods beginning after December 15, 2011. The adoption of ASU No. 2011-04 did not have a material impact on our statement of operations, financial position or cash flows.
