	(1)	QC Holdings, Inc. (“QC Holdings”) (f/k/a WhiteFence, Inc.) is the entity that holds the remaining assets of WhiteFence following the sale of substantially all of WhiteFence’s assets to Allconnect on October 28, 2013. The $2.8 million of net assets of QC Holdings consist primarily of a receivable related to the deferred payment from Allconnect and the legal rights to a patent. See Note 13, “Other income (loss).”
	(2)	On December 27, 2012, ICG acquired additional equity ownership interests in Bolt, increasing ICG’s ownership in that company to 53%; ICG began consolidating the financial position of Bolt as of that date. The results of operations of Bolt from the date of acquisition through December 31, 2012 were immaterial to ICG; accordingly, the results of operations of Bolt are included on ICG’s Consolidated Statements of Operations beginning on January 1, 2013. See Note 4, “Consolidated Businesses,” for additional information regarding ICG’s consolidation of Bolt.
	(3)	CIML was a consolidated company from July 11, 2012, when ICG increased its ownership in that company to 52%, to February 20, 2013, when ICG’s equity ownership interest in CIML was reduced to 38% as a result of the exercise of existing warrants and options, in conjunction with the sale of Channel Intelligence to Google. As a result of that sale, Channel Intelligence is presented as discontinued operations in the Consolidated Financial Statements for the relevant periods and is not included in the table above; mylist continues to be included in continuing operations in ICG’s Consolidated Financial Statements for the period for which it was consolidated.
	(4)	On March 30, 2012, ICG acquired 96% of MSDSonline and began consolidating the financial position of MSDSonline as of that date. The results of operations of MSDSonline from the date of acquisition through March 31, 2012 were immaterial to ICG; accordingly, the results of operations of MSDSonline are included on ICG’s Consolidated Statements of Operations beginning on April 1, 2012.

	2. Significant Accounting Policies
	Principles of Accounting for Ownership Interests
	The various interests that ICG acquires in its businesses are accounted for under one of three methods: the consolidation method, the equity method and the cost method. The applicable accounting method is generally determined based on ICG’s voting interest in a company.
	Consolidation. Businesses in which (1) ICG directly or indirectly owns more than 50% of the outstanding voting securities, and (2) other stockholders do not possess the right to affect significant management decisions are generally accounted for under the consolidation method of accounting. Participation of other stockholders in the net assets and in the earnings or losses of a consolidated subsidiary is reflected in the line items “Noncontrolling Interest” in ICG’s Consolidated Balance Sheets and “Net income attributable to the noncontrolling interest” in ICG’s Consolidated Statements of Operations. Noncontrolling interest adjusts ICG’s consolidated results of operations to reflect only ICG’s share of the earnings or losses of the consolidated subsidiary.
	Any changes in ICG’s ownership interest in a consolidated subsidiary, through additional equity issuances by the consolidated subsidiary or through ICG acquiring the shares from existing shareholders, in which ICG maintains control is recognized as an equity transaction, with appropriate adjustments to both ICG’s additional paid-in capital and the corresponding noncontrolling interests. The difference between the carrying amount of ICG’s ownership interest in the company and the underlying net book value of the company after the issuance of stock by the company is reflected as an equity transaction in ICG’s Consolidated Statements of Changes in Equity.
	An increase in ICG’s ownership interest in a business accounted for under the equity or cost method of accounting in which ICG obtains a controlling financial interest is accounted for as a step acquisition, with an allocation of the purchase price to the fair value of the net assets acquired. In addition, ICG remeasures its previously held ownership interest in a business that was previously not consolidated at the acquisition date fair value; any gain or loss resulting from this remeasurement is recognized in ICG’s Consolidated Statements of Operations at that time. ICG begins to include the financial position and operating results of the newly-consolidated subsidiary in its Consolidated Financial Statements from the date ICG obtains the controlling financial interest in that subsidiary. If control is lost, any retained interest is measured at fair value, and a gain or loss is recognized in ICG’s Consolidated Statements of Operations at that time. In addition, to the extent ICG maintains a smaller equity ownership, the accounting method used for that business is adjusted to the equity or cost method of accounting, as appropriate, for subsequent periods.
	Equity Method. Businesses that are not consolidated, but over which ICG exercises significant influence, are accounted for under the equity method of accounting and are referred to in the Notes to Consolidated Financial Statements as “equity method businesses.” The determination as to whether or not ICG exercises significant influence with respect to a company depends on an evaluation of several factors, including, among others, representation on the company’s board of directors and equity ownership level, which is generally between a 20% and a 50% interest in the voting securities of an equity method business, as well as voting rights associated with ICG’s holdings in common stock, preferred stock and other convertible instruments in that company. ICG’s share of the earnings and/or losses of the company, as well as any adjustments resulting from prior period finalizations of equity income/losses, are reflected in the line item “Equity loss” in ICG’s Consolidated Statements of Operations.
	An increase in ICG’s ownership interest in an equity method business over which ICG maintains significant influence is accounted for as a step acquisition, with an allocation of the excess purchase price to the fair value of the net assets acquired. A decrease in ICG’s ownership interest in an equity method business over which ICG maintains significant influence is accounted for as a dilution gain or loss in ICG’s Consolidated Statements of Operations and reflects the difference between ICG’s share of the underlying net assets of that company prior to the relevant change in ownership and ICG’s share of the underlying net assets of that company subsequent to the relevant change in ownership.
	Cost Method. Businesses not accounted for under either the consolidation method or equity method of accounting are accounted for under the cost method of accounting and are referred to in these Notes to Consolidated Financial Statements as “cost method businesses.” ICG’s share of the earnings and/or losses of cost method businesses is not included in ICG’s Consolidated Statement of Operations. However, impairment charges related to cost method businesses are recognized in ICG’s Consolidated Statements of Operations. If circumstances suggest that the value of a cost method business with respect to which an impairment charge has been made has subsequently recovered, that recovery is not recorded. The carrying values of ICG’s cost method businesses are reflected in the line item “Equity and cost method investments” in ICG’s Consolidated Balance Sheets.
	ICG initially records its carrying value in businesses accounted for under the cost method at cost, unless the equity securities of a cost method business have readily determinable fair values based on quoted market prices, in which case the interests are valued at fair value and are classified as marketable securities or some other classification in accordance with guidance for ownership interests in debt and equity securities.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Those estimates include evaluation of ICG’s convertible debt and equity holdings in businesses, holdings in marketable securities, asset impairment, revenue recognition, income taxes and commitments and contingencies. Those estimates and assumptions are based on management’s best judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, such as the current economic environment, that management believes to be reasonable under the circumstances. Management adjusts those estimates and assumptions when facts and circumstances dictate that it is necessary or appropriate to do so. It is reasonably possible that ICG’s accounting estimates with respect to the ultimate recoverability of ICG’s ownership interests in convertible debt and equity holdings, goodwill and the useful lives of intangible assets could change in the near term and that the effect of such changes on ICG’s consolidated financial statements could be material. Management believes the recorded amounts of goodwill, intangible assets, equity method businesses and cost method businesses were not impaired as of December 31, 2013.
	Cash and Cash Equivalents
	ICG considers all highly liquid instruments with an original maturity of approximately three months at the time of purchase to be cash equivalents. Cash and cash equivalents at December 31, 2013 and 2012 were invested principally in money market accounts and commercial paper.
	Restricted Cash
	ICG considers cash that is legally restricted and cash that is held as a compensative balance for letter of credit arrangements as restricted cash. ICG had no long-term restricted cash as of December 31, 2013 and 2012.
	Goodwill, Intangible Assets, Equity Method Businesses and Cost Method Businesses
	ICG evaluates its carrying value in equity method businesses and cost method businesses continuously to determine whether an other-than-temporary decline in the fair value of any such business exists and should be recognized. In order to make that determination, ICG considers each such business’ achievement of its business plan objectives and milestones, the fair value of its ownership interest in each such business (which, in the case of any company listed on a public stock exchange, is the quoted stock price of the relevant ownership interest), the financial condition and prospects of each such business, and other relevant factors. The business plan objectives and milestones ICG considers include, among others, those related to financial performance, such as achievement of planned financial results or completion of capital raising activities, and those that are not primarily financial in nature, such as obtaining key business partnerships or the hiring of key employees. Impairment charges are determined by comparing ICG’s carrying value of a business with its estimated fair value. Fair value is determined by using a combination of estimating the cash flows related to the relevant asset, including estimated proceeds on disposition, and an analysis of market price multiples of companies engaged in lines of business similar to the company being evaluated. ICG concluded that the carrying value of its equity method businesses and cost method businesses was not impaired as of December 31, 2013 and 2012.
	ICG tests goodwill for impairment annually during the fourth quarter of each year, or more frequently as conditions warrant, and tests intangible assets for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. ICG concluded that its goodwill and intangible assets were not impaired as of December 31, 2013 and 2012.
	Marketable Securities
	Marketable securities are reported at fair value, based on quoted market prices, with the net unrealized gain or loss reported as a component of “Accumulated Other Comprehensive Income” in ICG Group, Inc. Stockholders’ Equity on ICG’s Consolidated Statements of Changes in Equity.
	Financial Instruments
	Cash and cash equivalents, accounts receivable and accounts payable are carried at cost, which approximates fair value due to the short-term maturity of these instruments. Marketable securities are carried at fair value.
	Deferred Revenue
	Deferred revenue consists primarily of payments received in advance of revenue being earned under the relevant customer agreements.
	Revenue Recognition
	During the year ended December 31, 2013, ICG’s consolidated revenue was primarily attributable to Bolt, GovDelivery and MSDSonline. During the year ended December 31, 2012, ICG’s consolidated revenue was primarily attributable to GovDelivery and MSDSonline. During the year ended December 31, 2011, ICG’s consolidated revenue was attributable to GovDelivery.
	Bolt generates revenue from (1) software licenses, (2) maintenance and support services, (3) professional service fees, (4) insurance commissions and (5) subscription fees. Bolt’s software license revenue derives from licenses of its software products directly to end users and is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable; Bolt’s software license revenue is recognized ratably over the applicable contract term. Bolt’s maintenance and customer support fees are recognized ratably over the life of maintenance and support contracts, which is typically one year. Bolt’s professional service fees revenue relates to professional services for software licenses that require significant customization, integration and installation; that revenue is recognized ratably over the applicable contract term. Bolt’s commissions on the premiums from sales of insurance policies are recognized when Bolt has sufficient information to determine the amount that is owed, it is probable that the economic benefits associated with the transaction will flow to Bolt, and the costs incurred, or to be incurred, with respect to the transaction can be accurately measured. Finally, Bolt recognizes subscription fee revenue over the subscription period, which is generally one month.
	GovDelivery revenue consists of (1) nonrefundable setup fees and (2) monthly maintenance and hosting fees. Those fees generally are deferred and recognized as the services are performed, which is typically over the service term. Costs related to performing setup services are expensed as incurred.
	MSDSonline derives revenue from two sources: (1) subscription fees and (2) professional services fees. The vast majority of MSDSonline’s revenue is derived from subscription fees from customers accessing the business’ database and web-based tools; that revenue is recognized ratably over the applicable contract term, beginning on the contract implementation date. MSDSonline also generates professional services fees from (1) training, (2) authoring of material safety data sheets and (3) compiling customers’ online libraries of material safety data sheet documents and indexing those documents. The revenue derived from those fees is recognized on a percentage of completion basis over the applicable project’s timeline.
	Equity-Based Compensation
	ICG recognizes equity-based compensation expense in the Consolidated Financial Statements for all share options and other equity-based arrangements that are expected to vest. Equity-based compensation expense is measured at the date of grant, based on the fair value of the aware, and is recognized using the straight-line method over the employee’s requisite service period. Equity-based awards with vesting conditions other than service are recognized based on the probability that those conditions will be achieved.
	Research and Development
	Research and development costs are charged to expense as incurred.
	Income Taxes
	Income taxes are accounted for under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	Discontinued Operations
	During the year ended December 31, 2013, Channel Intelligence, InvestorForce and Procurian were sold. Accordingly, ICG has recast all financial information within this Report to conform to the current period presentation; those three businesses are presented as discontinued operations for all periods presented.
	Net Income (Loss) Per Share
	Basic net income (loss) per share (EPS) is computed using the weighted average number of common shares outstanding during a given period. Diluted EPS includes shares, unless anti-dilutive, that would arise from the exercise of stock options and conversion of other convertible securities and is adjusted, if applicable, for the effect on net income (loss) of such transactions. See Note 15, “Net Income (Loss) per Share.”
	Comprehensive Income (Loss)
	ICG reports and displays comprehensive income (loss) and its components in the Consolidated Statements of Operations and Comprehensive Income (Loss). Comprehensive income (loss) is the change in equity of a business enterprise during a period from non-owner sources. ICG’s sources of comprehensive income (loss) are net income (loss), and net unrealized appreciation on its marketable securities. Reclassification adjustments result from the recognition of gains or losses in net income that were included in comprehensive income (loss) in prior periods.
	Supplemental Cash Flow Disclosures
	In 2013, 2012 and 2011, ICG paid interest of $1.2 million, less than $0.1 million and $0.1 million, respectively. ICG made income tax payments of $0.3 million and $0.1 million in 2013 and 2012, respectively. ICG received income tax refunds of $6.5 million in 2011.
	Escrow Information
	When an interest in one of ICG’s businesses is sold, a portion of the proceeds may be held in escrow primarily to satisfy purchase price adjustments and/or indemnity claims. ICG records gains on escrowed proceeds at the time ICG is entitled to receive such proceeds, the amount is fixed or determinable and realization is assured. As of December 31, 2013, $29.1 million related to ICG’s potential proceeds from sales of former businesses remained in escrow to satisfy potential or unresolved indemnification claims. Those outstanding escrows are scheduled to be released at various dates within the next two years, subject to pending and potential indemnity claims pursuant to the terms of the specific sales agreements. On January 15, 2014, $0.3 million related to the sale of StarCite was released from escrow. ICG will recognize a gain in that amount during the first quarter of 2014.
	Concentration of Customer Base and Credit Risk
	For the years ended December 31, 2013, 2012 and 2011, none of the customers of ICG’s consolidated businesses represented more than 10% of ICG’s consolidated revenue.
	Commitments and Contingencies
	From time to time, ICG and its businesses are involved in various claims and legal actions arising in the ordinary course of business. ICG does not expect any liability with respect to any legal claims or actions that would materially affect its consolidated financial position or cash flows.
	Reclassifications
	Certain amounts in the prior year financial statements have been reclassified to conform to the current-year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net income (loss).
	Recent Accounting Pronouncements

	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-02, “Other Comprehensive Income (Topic 220)” (“ASU 2013-02”). The objective of ASU 2013-02 is to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 seeks to attain that objective by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. ASU 2013-02 was effective prospectively for ICG in its first quarter of 2013. The impact of the adoption of ASU 2013-02 was insignificant to the Consolidated Financial Statements.

	ICG has considered all other recently issued accounting pronouncements and does not believe the adoption of such pronouncements will have a material impact on its audited Financial Statements.

	During the year ended December 31, 2013, ICG revised its initial estimates of its allocation of value related to the 2012 consolidation of Bolt. Based on those revisions, ICG retrospectively increased the value of goodwill as of December 31, 2012 by $10.2 million, which was primarily offset by a decrease in intangible assets. See Note 4, “Consolidated Business” for additional information regarding the transactions impacting goodwill detailed in the table above.
	As of December 31, 2013 and 2012, all of ICG’s goodwill was allocated to its consolidated businesses.

	Amortization expense for intangible assets during the years ended December 31, 2013, 2012 and 2011 was $8.5 million, $4.8 million and $1.4 million, respectively. ICG amortizes intangible assets using the straight line method.
	During the year ended December 31, 2013, ICG revised its initial estimates related to the allocated value of Bolt in connection with the 2012 consolidation of that company. Accordingly, based on those revisions, ICG retrospectively decreased the value of intangible assets as of December 31, 2012 by $10.9 million. See Note 4, “Consolidated Business” for additional information regarding the transactions impacting intangibles detailed in the table above.
	Remaining estimated amortization expense is as follows (in thousands):

	Impairment
	ICG completed its annual impairment testing in the fourth quarter of each of 2013, 2012 and 2011. The completion of ICG’s annual impairment testing did not result in an impairment charge related to ICG’s consolidated businesses in any of those years; ICG’s fair value of its reporting units, including goodwill, substantially exceeds its carrying value. ICG estimates the fair value of its reporting units using a “Level 3” input (see Note 8, “Financial Instruments,” for the definition of a “Level 3” input) market approach by determining market multiples from comparable publicly-traded companies and applying those approximate multiples to the revenues of the reporting units, which are then compared to the respective carrying values of the reporting units. See Note 4, “Consolidated Businesses.” ICG also performs ongoing business reviews of its equity method companies and cost method companies. See Note 7, “Equity and Cost Method Businesses.”
	During the year ended December 31, 2012, GovDelivery decreased its liability related to contingent consideration payments for an acquisition because it believed that performance targets related to those contingent payments would not be achieved. As a result, GovDelivery performed an impairment analysis with respect to the associated intangible assets and goodwill recorded related to that acquisition, and recorded an impairment charge of $0.4 million related to the intangible assets and an impairment charge of $0.3 million related to goodwill that are reflected in the line item “Impairment related and other” in ICG’s Consolidated Statements of Operations for the year ended December 31, 2012. The $0.4 million impairment to intangibles is included in the $5.4 million accumulated amortization balance for customer relationships as of December 31, 2012 in the table above. In addition to the $0.7 million of impairments recorded by GovDelivery in 2012, GovDelivery also recorded a gain of $0.7 million to reverse a contingent consideration liability, which is also included in “Impairment related and other” on ICG’s Consolidated Statement of Operations during the year ended December 31, 2012.

	Acquisitions
	During 2012 and 2013, ICG completed the following acquisitions:
	(1) On March 30, 2012, ICG acquired 96% of the equity of MSDSonline. The acquisition was accounted for under the acquisition method. ICG allocated the purchase price to the acquired tangible and identifiable intangible assets and liabilities based upon their respective fair values as of the date of acquisition.
	(2) On December 27, 2012, ICG acquired additional equity ownership interests in Bolt (then an equity method business) for consideration of $13.2 million, increasing ICG’s ownership interest in that business from 38% to 53%. ICG consolidated the financial position of Bolt as of the date the additional equity interests were acquired and accounted for the transaction as a business combination. ICG allocated the value of Bolt to its tangible and identifiable intangible assets and liabilities based upon their respective estimated fair values as of the date of acquisition. Additionally, ICG recorded a gain on the transaction of $25.5 million, representing the excess of ICG’s portion of the enterprise value of Bolt over its carrying value for its prior equity interest in Bolt as an equity method company. That gain is included in the line item “Other income (loss), net” in ICG’s Consolidated Statements of Operations for the year ended December 31, 2012. The primary valuation technique used to measure the acquisition date fair value of Bolt immediately before the business combination was the backsolve option-pricing method.
	(3) On August 9, 2013, Bolt acquired Superior Access for $8.7 million in cash. Bolt has estimated the allocation of purchase price to the acquired tangible and identifiable intangible assets and liabilities based upon their respective estimated fair values at the date of acquisition. ICG expects the acquisition accounting related to Bolt’s acquisition of Superior Access to be complete by June 30, 2014.
	No other acquisitions occurred in 2013 or 2012 that were significant to ICG’s consolidated results.
	The allocations of the purchase price related to the acquisition of MSDSonline and Superior Access and the allocation of the value upon consolidation of Bolt to identified intangible assets and tangible assets and liabilities are as follows (in thousands):

		MSDSonline				Bolt			Superior

	-1	ICG estimated the fair value of the noncontrolling interest in Bolt and MSDSonline with consideration of discounts for lack of control and lack of marketability. See “Redeemable Noncontrolling Interest” in this Note 4 with respect to MSDSonline.
	Redeemable Noncontrolling Interest
	Certain GovDelivery stockholders have the ability to require GovDelivery to redeem their shares in 2014 based on a fair value determination. Because that redemption is outside the control of GovDelivery, ICG has classified this noncontrolling interest outside of equity and will accrete to its estimated redemption value with an offset to additional paid-in capital. This noncontrolling interest is classified as “Redeemable noncontrolling interest” on ICG’s Consolidated Balance Sheets.
	Certain MSDSonline stockholders have the ability to require MSDSonline to redeem their shares beginning in 2015 based on a fair value determination. Because that redemption is outside the control of MSDSonline, ICG has classified this noncontrolling interest outside of equity and will accrete to its estimated redemption value with an offset to additional paid-in capital. This noncontrolling interest is classified as “Redeemable noncontrolling interest” on ICG’s Consolidated Balance Sheets.
	The following reconciles the activity related to the redeemable noncontrolling interest during the years ended December 31, 2013, 2012 and 2011 (in thousands):

	Balance at December 31, 2010	$	1,182

	Impact of subsidiary equity transactions		(924	)
	Balance at December 31, 2013	$	3,442
	Other Consolidated Businesses Transactions
	From time to time, ICG acquires additional equity ownership interests in its consolidated businesses. Purchasing equity ownership interests from a consolidated business’s existing shareholders results in an increase in ICG’s controlling interest in that business and a corresponding decrease in the noncontrolling interest ownership. Those transactions are accounted for as a decrease to “Noncontrolling Interest” and a decrease to “Additional paid-in capital” on ICG’s Consolidated Balance Sheets for the relevant period. During the year ended December 31, 2013, ICG paid $11.0 million and $3.0 million to the noncontrolling interest holders of Bolt and GovDelivery, respectively, to purchase equity interests in those companies. ICG may also acquire additional equity ownership interests in its consolidated businesses as a result of share issuances by those companies or may be diluted by such share issuances. An issuance of equity securities by a consolidated business that results in a decrease in ICG’s equity ownership interests is accounted for in accordance with the policy for “Principles of Accounting for Ownership Interests” described in Note 2, “Significant Accounting Policies.” Other changes to ICG’s equity ownership interests in its consolidated businesses, as well as equity-based compensation award activity at those businesses, also result in adjustments to “Additional paid-in capital” and “Noncontrolling Interest” on ICG’s Consolidated Balance Sheets. The impact of any equity-related transactions at ICG’s consolidated businesses is included in the line item “Impact of subsidiary equity transactions” on ICG’s Consolidated Statements of Changes in Equity. The impact of these changes to the noncontrolling interest are also included in the line item “Impact of subsidiary equity transactions” on ICG’s Consolidated Statements of Changes in Equity for the years ended 2013, 2012 and 2011. These amounts primarily relate to ICG’s acquisition of additional equity ownership interests in our consolidated businesses from noncontrolling interests, as well as the impact of ICG’s consolidation of Bolt and CIML in 2012 on the noncontrolling interest.

	Other Equity Method Businesses Information
	During the year ended December 31, 2012, ICG participated in a follow-on equity financing transaction for Bolt (prior to ICG’s consolidation of the company). ICG acquired $9.0 million of Bolt preferred stock in the transaction, increasing its ownership in Bolt from 26% to 38%. Also during the year ended December 31, 2012, ICG purchased $13.2 million of Bolt preferred stock from existing shareholders, collectively increasing its ownership in Bolt from 38% to 53%. See Note 4, “Consolidated Businesses,” subsection “Acquisitions,” for additional information related to the consolidation of Bolt.
	Cost Method Businesses
	ICG’s carrying value of its holdings in cost method businesses was $19.6 million and $13.0 million as December 31, 2013 and 2012, respectively. Those amounts are reflected in the line item “Equity and cost method businesses” on ICG’s Consolidated Balance Sheets as of the relevant dates.

	ICG owns approximately 9% of Anthem Ventures Fund, L.P. (formerly eColony, Inc.) and Anthem Ventures Annex Fund, L.P. (collectively, “Anthem”), which invest in technology companies. ICG acquired its interest in Anthem in 2000 and currently has no carrying value in Anthem. Accordingly, the receipt of distributions from Anthem by ICG would result in a gain at the time ICG receives those distributions.

	Marketable Securities

	Marketable securities represent ICG’s holdings of publicly-traded equity securities and are accounted for as available-for-sale securities. During the years ended December 31, 2012 and 2011, ICG received, and subsequently sold, publicly-traded equity securities that it has accounted for as marketable securities. ICG does not hold any marketable securities as of December 31, 2013. The fair value of the shares of Active common stock held by ICG as of December 31, 2012 of $0.7 million is reflected in both the line item “Marketable Securities” ($0.3 million) and the line item “Prepaid expenses and other current assets” ($0.4 million) on ICG’s Consolidated Balance Sheets. See Note 13, “Other Income (Loss)” for additional information related to the receipt and sale of marketable securities.
	Impairments
	ICG performs ongoing business reviews of its equity and cost method businesses to determine whether ICG’s carrying value in those businesses is impaired. ICG determined its carrying value in its equity and cost method businesses was not impaired during the years ended December 31, 2013, 2012 and 2011.

	Fair Value Measurements
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. There are three levels of inputs that may be used to measure fair value, which are as follows:
	Level 1 – Observable inputs, such as quoted market prices for identical assets and liabilities in active public markets.
	Level 2 – Observable inputs other than Level 1 prices based on quoted prices in markets with insufficient volume or infrequent transactions, or valuations in which all significant inputs are observable for substantially the full term of the asset or liability.
	Level 3 – Unobservable inputs to the valuation techniques that are significant to the fair value of the asset or liability.
	Assets and liabilities are measured at fair value based on one or more of the following three valuation techniques:
	Market Approach – Fair value is determined based on prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities.
	Income Approach – Fair value is determined by converting relevant future amounts to a single present amount, based on market expectations (including present value techniques and option pricing models).
	Cost Approach – Fair value represents the amount that currently would be required to replace the service capacity of the relevant asset (often referred to as replacement cost).
	The fair value hierarchy of ICG’s financial assets measured at fair value on a recurring basis was as follows (in thousands):

		Asset (liability) at		Valuation		Level 1		Level 2		Level 3

	During the year ended December 31, 2012, GovDelivery determined that the estimated fair value of its acquisition contingent consideration obligations had changed with respect to a prior acquisition. The contingent consideration liability had an estimated fair value of $0.7 million, which was determined at the acquisition date, and was written down to the current estimated fair value of zero which resulted in a gain of $0.7 million that is included in “Impairment related and other” on ICG’s Consolidated Statements of Operations. In conjunction with this determination, GovDelivery also performed an impairment analysis of intangible assets and goodwill that were recorded related to the acquisition. See Note 3, “Goodwill and Intangibles, net.”
	The carrying value of certain of ICG’s other financial instruments, including accounts receivable and accounts payable approximates fair value due to the short-term nature of those instruments. The fair value of ICG’s long-term debt is based on assumptions concerning the amount and timing of estimated future cash flows and assumed risk-adjusted discount rates. See Note 9, “Debt” for further discussion. ICG’s non-financial assets measured on a non-recurring basis using the market approach were as follows (in thousands):

Both debt instruments are secured by Bolt’s assets, and both mature on May 1, 2016. Those debt instruments have a fair value as of December 31, 2013 and 2012 of $9.2 million and $9.3 million, respectively, due to warrants issued by Bolt to Horizon in connection with the debt agreement, and are included in the line item “Term loans and lines of credit” in the table above. As of December 31, 2013 and 2012, $9.7 million and $10.0 million, respectively, was outstanding under those loan agreements. There are prepayment penalties associated with these arrangements.
	On August 9, 2013, as part of a debt financing, Bolt entered into certain debt agreements with Neurone II Investments G.P. Ltd. (“Neurone”). Those agreements provide for a term loan of $0.5 million that is subject to an interest rate of 8.0% and matures on August 9, 2014. Those debt instruments have a fair value as of December 31, 2013 of $0.5 million, due to warrants issued by Bolt to Neurone in connection with the debt agreement. As of December 31, 2013, $0.5 million is outstanding under the term loan, which is included in the line item “Term loans and lines of credit” in the table above.
	On November 30, 2012, GovDelivery entered into loan agreements with Venture Bank that provided for a $2.0 million revolving credit facility that matured on November 30, 2013, and a $2.5 million term loan that matures on November 30, 2017, in order to fund GovDelivery’s 2013 initiatives of replacing existing equipment and expanding the company’s data centers. Both the revolving credit facility and the term loan are secured by GovDelivery’s assets and mature. Each of the line of credit and the term loan bears interest at a base rate equal to the prime rate plus 2.0% but in no case will be less than 5.5%. There was no amount outstanding under the line of credit as of December 31, 2013 and $2.2 million was outstanding under the term loan as of December 31, 2013. The term loan has a fair value as of December 31, 2013 of $2.2 million. There was no amount outstanding under the line of credit as of December 31, 2012; there was $2.5 million outstanding under the term loan as of December 31, 2012. The fair value of the term loan as of December 31, 2012 was $2.4 million. The amounts outstanding for each period are included in the line item “Term loans and lines of credit” in the table above. In January 2014, GovDelivery repaid the term loan; accordingly, the $2.2 million outstanding balance as of December 31, 2013 was included in the line item “Current maturities of long term debt” on ICG’s Consolidated Balance Sheets as of December 31, 2013.

Generally, the grants vest over a period from one to four years and expire eight to ten years after the grant date. Most businesses in which ICG holds equity ownership interests also maintain their own equity incentive/compensation plans.
	ICG issues the following types of equity-based compensation to its employees and non-employee directors: (1) stock appreciation rights (SARs), (2) stock options, (3) restricted stock (often subject to performance-based or market-based conditions) and (4) deferred stock units (DSUs). ICG’s grants of equity-based compensation are approved by the Compensation Committee of its Board of Directors.

	Each SAR represents the right of the holder to receive, upon exercise of that SAR, shares of ICG Common Stock equal to the amount by which the fair market value of a share of that Common Stock on the date of exercise of the SAR exceeds the base price of the SAR. The base price is determined by the NASDAQ closing price of ICG’s Common Stock on the date of grant (or the closing price on the next trading day if there are no trades in ICG’s stock on the date of grant). The fair value of each SAR is estimated on the grant date using the Black-Scholes option-pricing model. SARs generally vest over four years, with 25% vesting on the first anniversary of the grant date, and the remaining 75% vesting ratably each month over the subsequent 36 months.

	Stock Options
	The fair value of each stock option is estimated on the grant date using the Black-Scholes option-pricing model. Stock options generally vest ratably over four years: 25% vest on the first anniversary of the grant date, and the remaining 75% vest ratably on a monthly basis over the subsequent 36 months.

The weighted average remaining contractual life of the stock options outstanding as of December 31, 2013 was 5.3 years; those stock options had an aggregate intrinsic value as of December 31, 2013 of less than $0.1 million.
SARs and Stock Options Fair Value Assumptions
ICG estimates the grant date fair value of SARs and stock options using the Black-Scholes option-pricing model, which requires the input of highly subjective assumptions. Those assumptions include estimating the expected life of the award and estimating volatility of ICG’s stock price over the expected term. Expected volatility approximates the historical volatility of ICG’s Common Stock over the period commensurate with the expected term of the award. The expected term calculation is based on an average of the award vesting term and the life of the award. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for an instrument with a maturity that is commensurate with the expected term of the award. Changes in the above assumptions, the estimated forfeitures and/or the requisite service period can materially affect the amount of equity-based compensation recognized on ICG’s Consolidated Statements of Operations.
The following assumptions were used to determine the fair value of SARs granted to employees and a non-management director by ICG during the years ended December 31, 2013, 2012 and 2011:

		Years Ended December 31,
		2013				2012			2011
Expected volatility			56	%			56	%		56	%
Average expected life of SAR (in years)			6.25				6.25			5.25-6.25
Risk-free interest rate			1.86	%			0.92	%		1.62-1.97	%
Dividend yield			0	%			0	%		0	%
Restricted Stock
ICG periodically issues shares of restricted stock to its employees and non-management directors. Recipients of restricted stock do not pay cash consideration for the shares and have the right to vote all shares subject to the grant and receive all dividends with respect to the shares, whether or not the shares have vested. As of December 31, 2013, issued and unvested shares of restricted stock granted to ICG’s employees vest as follows: (1) 57,248 shares of restricted stock vest 25% each year over a four-year period, (2) 49,967 shares of restricted stock vest 12.5% on the nine-month anniversary of the grant date, and the remaining 87.5% every six months subsequent to the first vesting date and (3) 130,440 shares of restricted stock vest upon the achievement of certain performance goals, as discussed below. Additionally, as of December 31, 2013, 916,666 shares of restricted stock granted to ICG’s Chief Executive Officer and ICG’s President are subject to vesting in accordance with the lapse of specified service periods, and the achievement of certain performance goals and market conditions, as discussed below.
During the year ended December 31, 2013, in lieu of their right to receive 50% of their respective target bonus amounts under the ICG 2013 Performance Plan (the “Performance Plan”) in cash, senior ICG employees, including each of ICG’s executive officers, were issued a total of 130,440 shares of restricted stock (the “Performance Shares”) (determined based on the value of 50% of their respective individual target bonuses under the Performance Plan and the closing price of ICG’s common stock of $13.09 per share on March 1, 2013, the date of the restricted stock grant). If and to the extent that an individual’s achievement percentage under the Performance Plan (1) is greater than or equal to 50%, all of that employee’s Performance Shares will vest or (2) is greater than 0% but less than 50%, a portion of that employee’s Performance Shares equal to two times the achievement percentage will vest. All of those performance-based restricted stock awards vested during the first quarter of 2014.

As of December 31, 2013, outstanding shares of restricted stock granted to ICG’s Chief Executive Officer and ICG’s President vest as follows: (1) 183,334 shares of restricted stock vest in equal installments each November and May through November 9, 2015, (2) 366,666 shares of restricted stock vest based on the achievement of stipulated performance goals related to ICG’s consolidated revenue and EBITDA performance on or before December 31, 2015, and (3) 366,666 shares of restricted stock vest based on stipulated market thresholds related to ICG’s Common Stock price through December 31, 2015. As of December 31, 2013, ICG determined that, following the closing of the sale of Procurian to an affiliate of Accenture on December 4, 2013, the stipulated performance goals related to the performance-based restricted stock awards are improbable of achievement. Accordingly, ICG has reversed previously-recorded equity compensation cost related to those awards in the amount of $1.5 million. That equity compensation cost had been recognized as follows: $0.4 million, $0.9 million and $0.2 million was recognized during the years ended December 31, 2013, 2012 and 2011, respectively. Subsequent to December 31, 2013, in light of the sale of Procurian and the improbability of the achievement of the performance-based awards, both ICG’s Chief Executive Officer and ICG’s President elected to forfeit those shares of restricted stock. In the event of a change of control (as defined by the Plan) before December 31, 2015, all of the shares contingent upon the achievement of the stock price metrics would automatically vest, and any unrecognized equity-based compensation expense associated with those awards would be immediately recognized. Additionally, in the event of a change of control during which ICG’s Chief Executive Officer and ICG’s President are terminated, any remaining service-based awards would automatically vest, and any unrecognized equity-based compensation expense associated with those awards would be immediately recognized.

During the years ended December 31, 2013 and 2012, ICG granted 30,750 shares and 18,750 shares, respectively, of restricted stock under ICG’s Amended and Restated Non-Management Director Compensation Plan (the “Director Plan”), which are included in the table below. See “Non-Management Director Equity-Based Compensation” in this Note 12 for additional details related to vesting.
Share activity with respect to restricted stock awards during the years ended December 31, 2013, 2012 and 2011 was as follows:

		Number of				Weighted Average

The total aggregate fair value of restricted stock awards that vested and were converted to ICG’s Common Stock during the years ended December 31, 2013, 2012 and 2011 was $2.6 million, $1.3 million and $0.2 million, respectively. During the years ended December 31, 2013, 2012 and 2011, 46,616 shares, 39,817 shares and 3,351 shares, respectively, were surrendered for satisfying withholding taxes. As of December 31, 2013, ICG expects 818,405 shares of restricted stock to vest in the future.

Subsequent to December 31, 2013, ICG granted 158,942 shares of restricted stock to certain ICG employees that will vest upon the achievement of performance metrics in accordance with ICG’s established 2014 performance plan. These shares were valued at approximately $3.2 million.

Subsequent to December 31, 2013, ICG granted 2,575,000 shares of restricted stock to ICG’s executive officers and management valued at $52.3 million. These shares vest upon the achievement of stipulated market thresholds related to ICG’s Common Stock price through February 28, 2016.
Non-Management Director Equity-Based Compensation
ICG periodically issues DSUs and/or shares of restricted stock to its non-management directors in accordance with the Director Plan. Each DSU represents a share of Common Stock into which that DSU will be converted upon the termination of the recipient’s service at ICG. DSUs issued annually under the Director Plan vest on the one-year anniversary of the grant date.
Share activity with respect to the annual DSU awards for the years ended December 31, 2013, 2012 and 2011 are as follows:

		Number of				Weighted Average
		DSUs				Grant Date
						Fair Value
Issued and unvested as of December 31, 2010			31,500			$	6.8
Granted			60,000			$	13.32
Vested			(39,000	)		$	8.05
Issued and unvested as of December 31, 2011			52,500			$	13.32
Granted			41,250			$	8.4
Vested			(52,500	)		$	13.32
Issued and unvested as of December 31, 2012			41,250			$	8.4
Granted			29,250			$	13.09
Vested			(41,250	)		$	8.4
Issued and unvested as of December 31, 2013			29,250			$	13.09
As of December 31, 2013, ICG expects 29,250 DSUs related to the annual grant program under the Director Plan to vest in the future.
Each non-management director is also entitled to receive quarterly cash payments for his service on the Board of Directors and its committees, as applicable, under the Director Plan. Each director may elect to receive DSUs in lieu of all or a portion of those cash fees. Each participating director receives DSUs representing shares of ICG’s Common Stock with a fair market value equal to the relevant cash fees (with such fair market value determined by reference to the closing Common Stock price reported by NASDAQ on the date these cash fees otherwise would have been paid). DSUs received in lieu of cash fees are fully vested at the time they are granted and are settled in shares of ICG’s Common Stock upon the termination of the recipient’s service at ICG. The expense for those DSUs is recorded when the fees to which the DSUs relate are earned and is included in the line item “general and administrative” on ICG’s Consolidated Statements of Operations (but is not reflected in the summarized Equity-Based Compensation table above).
Share activity with respect to periodically-issued DSUs for the years ended December 31, 2013, 2012 and 2011 was as follows:

		Number of				Weighted Average
		DSUs				Grant Date
						Fair Value
Issued and unvested as of December 31, 2010			—			$	—

Expense associated with the DSUs periodically issued in lieu of cash for the years ended December 31, 2013, 2012 and 2011 was $0.4 million, $0.3 million and $0.2 million, respectively.
Consolidated Businesses
All of ICG’s consolidated businesses issue equity-based compensation awards to their employees. Those awards are most often in the form of stock options that vest over four years. The fair value of the stock option awards is estimated on the grant date using the Black-Scholes option pricing model. The majority of the stock options vest 25% on the first anniversary of the grant date, and the remaining 75% vest ratably each month over the subsequent 36 months. The other awards generally vest ratably over four years, with 25% vesting on each anniversary date over that term.

	On December 27, 2012, ICG acquired additional equity interests in Bolt and began to consolidate the financial position and results of Bolt as of that date. ICG recorded a gain on the transaction of $25.5 million, which represents the excess of the fair value at the date of consolidation over its carrying value from its previous equity interest as an equity method business. That gain is included in the line item “Gain on fair value of prior equity interests” for the year ended December 31, 2012 in the table above. See Note 4, “Consolidated Businesses” for the allocation of the enterprise value.

	On July 11, 2012, ICG acquired additional equity interests in CIML and began to consolidate the financial position and results of CIML as of that date. In conjunction with the fair value determination of ICG’s previous equity interest in CIML, ICG recorded a gain of $26.2 million, representing the excess of ICG’s portion of the value of CIML over its carrying value from its previous equity interest as an equity method business at the date of consolidation; that gain is included in the line item “Gain on fair value of prior equity interests” for the year ended December 31, 2012 in the table above. The primary valuation technique used to measure the acquisition date fair value of CIML immediately before the acquisition was the backsolve option-pricing method.

	On October 18, 2013, Freeborders was sold to Symbio. ICG received an equity ownership interest in Symbio as consideration for this transaction. ICG recorded a gain on that transaction of $0.3 million that is included in the line item “Gain (loss) on sales/distributions of ownership interests” for the year ended December 31, 2013 in the table above.

	On October 28, 2013, substantially all of the assets of WhiteFence were sold to Allconnect. ICG’s portion of the proceeds was $5.4 million of cash, $1.6 million of which was deferred for one year. ICG recorded a loss on that transaction of $4.3 million that is included in the line item “Gain (loss) on sales/distributions of ownership interests” for the year ended December 31, 2013 in the table above.

	On July 5, 2012, GoIndustry was sold to Liquidity Services. ICG’s portion of the proceeds was $2.9 million of cash, which was received in July 2012. During the three-month period ended September 30, 2012, ICG recorded its share of the sale transaction costs incurred by GoIndustry, and, accordingly, ICG’s carrying value of GoIndustry was reduced to zero as of the date of the transaction. ICG recorded a gain of $2.9 million for the proceeds received during the year ended December 31, 2012, which is included in the line item “Gain (loss) on sales/distributions of ownership interests” in the table above.
	On February 17, 2011, Metastorm was sold to Open Text. ICG’s portion of the sale proceeds was $53.0 million; $51.3 million of those proceeds were received at closing on February 17, 2011, and the remaining proceeds were placed in escrow in connection with a customary indemnification holdback. As a result of that transaction and the related receipt of escrowed proceeds, ICG recorded gains of $26.0 million during the year ended December 31, 2011. During the year ended December 31, 2012, ICG received $0.2 million of escrowed proceeds, representing the final distribution of escrowed proceeds. ICG recorded those amounts as gains, which are included in the line item “Gain (loss) on sales/distributions of ownership interests” in the relative periods in the table above.

	On December 30, 2011, StarCite was sold to Active. ICG’s portion of the sale proceeds was $24.9 million, which consisted of $15.8 million of cash and 615,862 shares of Active common stock valued at $8.4 million, based on the $13.60 closing price of the stock on December 30, 2011. Approximately $0.1 million of the cash consideration and 102,199 shares of the stock consideration were placed in escrow to satisfy potential indemnity claims. ICG recorded a gain on that transaction of $14.1 million during the year ended December 31, 2011 that is included in the line item “Gain (loss) on sales/distributions of ownership interests” in the table above. During the year ended December 31, 2012, in conjunction with the release of 83,627 shares of Active common stock and a deminimis amount of cash from escrow, ICG recorded a gain of $0.4 million, which is also included in the line item “Gain (loss) on sales/distributions of ownership interests” for that year in the table above.

	As noted above, ICG’s portion of the StarCite sale proceeds included shares of Active common stock, some of which were held in escrow for a period of time to satisfy potential indemnity claims. During the years ended December 31, 2013 and 2012, ICG realized proceeds of $0.8 million and $7.5 million, respectively, from the sale of 150,233 shares of Active common stock at an average price of $5.10 per share in the 2013 period, and 447,057 shares of Active common stock at an average price of $16.88 per share in the 2012 period. ICG recorded a gain on the sale of those securities of less than $0.1 million and $1.4 million during the years ended December 31, 2013 and 2012, respectively. Those gains are included in the line item “Realized gains on sales of marketable securities” in the relative periods in the table above. On various dates during the year ended December 31, 2012, ICG determined that the price per share at which shares of Active common stock were recorded on ICG’s Consolidated Balance Sheets exceeded the fair value price per share of those securities. Accordingly, during the year ended December 31, 2012, ICG recorded impairment charges of $0.6 million related to the mark-to-market adjustment on Active common stock. That impairment charge is included in the line item “Other” for the year ended December 31, 2012 in the table above.

	During the year ended December 30, 2012, ICG received 12,989 shares of Intercontinental Exchange, Inc. (“ICE”), representing the final distribution of escrow proceeds related to the disposition of Creditex Group, Inc. ICG recorded a gain during the year ended December 31, 2012 of $1.7 million based on the closing stock price of the ICE common stock on the day it was released from escrow; that gain is included in the line item “Gain (loss) on sales/distributions of ownership interests” in the relative period in the table above. Subsequent to the receipt of those shares of ICE common stock, ICG sold the shares and received total proceeds of $1.8 million. The incremental gain on the sale of those shares of $0.1 million is included in the line item “Realized gains on the sales of marketable securities” for the year ended December 31, 2012 in the table above.

	On June 14, 2011, Channel Intelligence acquired substantially all of the assets of ClickEquations, primarily in exchange for Channel Intelligence preferred stock that was distributed to ClickEquations’ stockholders, including ICG. The transaction diluted ICG’s ownership in Channel Intelligence and, accordingly, ICG recorded a dilution gain of $0.5 million during the year ended December 31, 2011, which is included in the line item “Dilution gain on equity method businesses” in the table above. Based on the excess of the specified value of the Channel Intelligence preferred stock received by ICG in the transaction over ICG’s carrying value of ClickEquations on the transaction date, ICG recorded a loss on the sale of ClickEquations in the amount of $0.8 million. The loss on the sale transaction is included in the line item “Gain (loss) on sales/distributions of ownership interests” during the year ended December 31, 2011 in the table above.

	During the year ended December 31, 2011, ICG received escrowed proceeds and/or settlement payments related to several former businesses in which ICG had debt or equity ownership interests. ICG recorded aggregate gains of $1.6 million related to the receipt of those funds, which are included in the line item “Gain (loss) on sales/distributions of ownership interests” for the year ended December 31, 2011 in the table above.

	Also during the year ended December 31, 2011, ICG received a distribution from Anthem in the amount of $1.9 million, which was recorded as a gain and is included in the line item “Gains on other distributions” in the table above.

	Income tax (benefit) expense
	ICG Group, Inc., GovDelivery, InvestorForce (through January 29, 2013, the date of disposition), MSDSonline (beginning March 30, 2012, the date of acquisition) and Procurian (through December 4, 2013, the date of disposition) file a consolidated federal income tax return. ICG recorded consolidated income tax expense of $0.1 million for the year ended December 31, 2013. A significant amount of ICG’s overall tax expense relates to Procurian which is now presented as discontinued operations. The current federal income tax benefit recognized in 2013 of $17.7 million is offset by a $17.7 million income tax expense in discontinued operations since there was a loss in continuing operations and income in discontinued operations in that same year. There was not a similar benefit in 2012 or 2011, as there was income in both continuing operations and discontinued operations in those years. There was current tax expense recognized for state income taxes. For deferred income taxes, after evaluating all the positive and negative evidence, both historical and prospective, and determining it is not more likely than not to be realized, ICG maintains a full valuation allowance against its net deferred tax assets; therefore, no deferred tax expense was recorded in 2013. Amounts for 2012 and 2011 included in the table above are not recast to reflect what is reported in discontinued operations; rather, it is noted that $1.2 million of the $1.3 million income tax expense for 2012 and $3.8 million of the $4.3 million income tax benefit for 2011 are included in the line item “Income (loss) from discontinued operations, including gain on sale, net of tax” on ICG’s Consolidated Statements of Operations for those respective years. ICG recorded a consolidated income tax expense of $1.3 million during the year ended December 31, 2012. That income tax expense includes a benefit of $0.8 million related to the result of reconciliation of tax depreciation expense on fixed assets, which relates to periods prior to Procurian being a consolidating member of our consolidated tax return. ICG has determined that this amount is immaterial to all applicable periods, which encompasses the years of 2009 to 2012. ICG recorded a consolidated income tax benefit of $4.3 million during the year ended December 31, 2011. That benefit is comprised of $4.5 million of net deferred tax benefit related to the release of certain valuation allowances at Procurian, a tax benefit of $0.3 million for a return-to-provision adjustment for alternative minimum taxes from 2010 and a tax benefit of $0.2 million related to interest received on an income tax refund, partially offset by state and foreign tax expense from operations at Procurian.
	As a result of a change in ownership under Internal Revenue Code Section 382 that occurred in 2004, ICG’s net operating loss carryforwards and capital loss carryforwards are subject to an annual limitation. The annual limitation on the utilization of these carryforwards is approximately $14.5 million. This annual limitation can be carried forward if it is not used. ICG did not use the limitation in 2009; therefore, the amount available for 2010 was $29.0 million, all of which was used in 2010. ICG did not use the limitation in 2011 or 2012; therefore, the amount available for 2013 was $43.5 million, all of which was used in 2013 to offset the capital gains realized in 2013. The total amount available in future years for these carryforwards at December 31, 2013 was $145.2 million. These losses expire in varying amounts between 2018 and 2023.
	Additionally, as of December 31, 2013, ICG consolidated had $82.0 million of net operating loss carryforwards that are not subject to the Section 382 annual limitation. These net operating losses expire between 2018 and 2033. Of this amount, approximately $15.0 million is attributable to excess deductions for equity compensation, the benefit of which will be recorded to additional paid-in capital when realized.
	GovDelivery joined in filing a consolidated federal income tax return with ICG beginning in 2010. At the time of acquisition, GovDelivery had approximately $2.8 million of net operating loss carryforwards. ICG’s acquisition of GovDelivery constituted a change in ownership under Internal Revenue Code Section 382. As a result, these net operating losses are limited to approximately $1.0 million per year, plus any recognized built-in gains. As of December 31, 2013, all of these NOLs are available. GovDelivery’s net deferred tax liability after acquisition accounting of $4.8 million reduced ICG’s valuation allowance.
	MSDSonline joined in ICG’s consolidated federal tax return beginning on March 30, 2012 (when it was acquired). MSDSonline had NOLs totaling approximately $50.9 million when it was acquired. These NOLs expire in varying amounts between 2019 and 2031. The acquisition of MSDSonline constituted a change in ownership under Internal Revenue Code Section 382. The annual limitation on the utilization of MSDSonline’s NOLs equals approximately $1.7 million plus recognized built-in gains. Approximately $47.4 million of NOLs are expected to be available as a result of this limitation, of which, $9.4 million is currently available and included in the $82.0 million of NOLs that are not subject to the Section 382 limitations noted above.
	ICG’s net deferred tax asset (liability) consists of the following (in thousands):

	After evaluating all positive and negative evidence, both historical and prospective, and determining it is not more likely than not to be realized, ICG has recorded a full valuation allowance against its net deferred tax assets as of December 31, 2013. The net deferred tax asset as of December 31, 2012 is included in the line item “Assets of Discontinued Operations” on ICG’s Consolidated Balance Sheets.

	ICG’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. ICG had no material accrual for interest or penalties on ICG’s Consolidated Balance Sheets at December 31, 2013, 2012 or 2011. ICG recognized an income tax benefit related to $0.2 million of interest received in conjunction with the aforementioned refunds, which is included in ICG’s Consolidated Statements of Operations for the year ended December 31, 2011. There were no interest and/or penalties in ICG’s Consolidated Statements of Operations for the year ended December 31, 2012 or 2013.
	Tax years 2009 and forward are subject to examination for federal tax purposes. Tax years 1998 through 2008 are subject to examination for federal tax purposes to the extent of net operating losses used in future years.
	The effective tax rate differs from the federal statutory rate as follows:

		Year Ended December 31,
		2013			2012			2011
	Tax expense (benefit) at statutory rate		(35.0	)%		35	%		35	%

	The results of operations of our businesses are reported in two segments: the “vertical cloud” reporting segment and the “vertical cloud (venture)” reporting segment. Our vertical cloud reporting segment reflects the aggregate financial results of our businesses (1) that share the economic and other characteristics described above, (2) in which our management takes a very active role in providing strategic direction and operational support and (3) towards which we devote relatively large proportions of our personnel, financial capital and other resources. As of the date of this Report, we own majority controlling equity positions in (and therefore consolidate the financial results of) each of the three businesses in our vertical cloud segment. Our vertical cloud (venture) reporting segment includes businesses with many characteristics similar to those of the businesses in our vertical cloud segment, but in which we take a less active role in terms of strategic direction and operational support, and, accordingly, towards which we devote relatively small amounts of personnel, financial capital and other resources.
	Approximately $2.5 million, $1.0 million and $0.6 million of ICG’s consolidated revenue for the years ended December 31, 2013, 2012 and 2011, respectively, relates to sales generated outside of the United States, primarily Europe and Canada. As of December 31, 2013 and 2012, ICG’s assets were located primarily in the United States.
	The following summarizes selected information related to ICG’s segments for the years ended December 31, 2013, 2012 and 2011. The amounts presented as “Dispositions” in the following table represent businesses reported as discontinued operations as of December 31, 2013 and ICG’s share of businesses’ results that had been accounted for under the equity method of accounting that were disposed during the years ended December 31, 2013, 2012 and 2011. Businesses reported as discontinued operations as of December 31, 2013 include the following: (1) Procurian, which was sold to Accenture on December 4, 2013, (2) Channel Intelligence, which was sold to Google on February 20, 2013, and (3) InvestorForce, which was sold to MSCI on January 29, 2013. Businesses that were accounted for under the equity method of accounting and were disposed of during the three years ended December 31, 2013 include the following: (1) WhiteFence, substantially all of the assets of which were acquired by Allconnect on October 28, 2013, (2) Freeborders, which was merged with Symbio on October 18, 2013, (3) GoIndustry, which was sold to Liquidity Services on July 5, 2012, (4) StarCite, which was sold to Active on December 30, 2011, (5) ClickEquations, substantially all of the assets of which were acquired by Channel Intelligence on June 14, 2011, and (6) Metastorm, which was sold to Open Text on February 17, 2011.

Significant Accounting Policies (Policies)	Dec. 31, 2013
Principles of Accounting for Ownership Interests	'
	Principles of Accounting for Ownership Interests
	The various interests that ICG acquires in its businesses are accounted for under one of three methods: the consolidation method, the equity method and the cost method. The applicable accounting method is generally determined based on ICG’s voting interest in a company.
Consolidation	'
	Consolidation. Businesses in which (1) ICG directly or indirectly owns more than 50% of the outstanding voting securities, and (2) other stockholders do not possess the right to affect significant management decisions are generally accounted for under the consolidation method of accounting. Participation of other stockholders in the net assets and in the earnings or losses of a consolidated subsidiary is reflected in the line items “Noncontrolling Interest” in ICG’s Consolidated Balance Sheets and “Net income attributable to the noncontrolling interest” in ICG’s Consolidated Statements of Operations. Noncontrolling interest adjusts ICG’s consolidated results of operations to reflect only ICG’s share of the earnings or losses of the consolidated subsidiary.
	Any changes in ICG’s ownership interest in a consolidated subsidiary, through additional equity issuances by the consolidated subsidiary or through ICG acquiring the shares from existing shareholders, in which ICG maintains control is recognized as an equity transaction, with appropriate adjustments to both ICG’s additional paid-in capital and the corresponding noncontrolling interests. The difference between the carrying amount of ICG’s ownership interest in the company and the underlying net book value of the company after the issuance of stock by the company is reflected as an equity transaction in ICG’s Consolidated Statements of Changes in Equity.
	An increase in ICG’s ownership interest in a business accounted for under the equity or cost method of accounting in which ICG obtains a controlling financial interest is accounted for as a step acquisition, with an allocation of the purchase price to the fair value of the net assets acquired. In addition, ICG remeasures its previously held ownership interest in a business that was previously not consolidated at the acquisition date fair value; any gain or loss resulting from this remeasurement is recognized in ICG’s Consolidated Statements of Operations at that time. ICG begins to include the financial position and operating results of the newly-consolidated subsidiary in its Consolidated Financial Statements from the date ICG obtains the controlling financial interest in that subsidiary. If control is lost, any retained interest is measured at fair value, and a gain or loss is recognized in ICG’s Consolidated Statements of Operations at that time. In addition, to the extent ICG maintains a smaller equity ownership, the accounting method used for that business is adjusted to the equity or cost method of accounting, as appropriate, for subsequent periods.
Equity Method	'
	Equity Method. Businesses that are not consolidated, but over which ICG exercises significant influence, are accounted for under the equity method of accounting and are referred to in the Notes to Consolidated Financial Statements as “equity method businesses.” The determination as to whether or not ICG exercises significant influence with respect to a company depends on an evaluation of several factors, including, among others, representation on the company’s board of directors and equity ownership level, which is generally between a 20% and a 50% interest in the voting securities of an equity method business, as well as voting rights associated with ICG’s holdings in common stock, preferred stock and other convertible instruments in that company. ICG’s share of the earnings and/or losses of the company, as well as any adjustments resulting from prior period finalizations of equity income/losses, are reflected in the line item “Equity loss” in ICG’s Consolidated Statements of Operations.
	An increase in ICG’s ownership interest in an equity method business over which ICG maintains significant influence is accounted for as a step acquisition, with an allocation of the excess purchase price to the fair value of the net assets acquired. A decrease in ICG’s ownership interest in an equity method business over which ICG maintains significant influence is accounted for as a dilution gain or loss in ICG’s Consolidated Statements of Operations and reflects the difference between ICG’s share of the underlying net assets of that company prior to the relevant change in ownership and ICG’s share of the underlying net assets of that company subsequent to the relevant change in ownership.
Cost Method	'
	Cost Method. Businesses not accounted for under either the consolidation method or equity method of accounting are accounted for under the cost method of accounting and are referred to in these Notes to Consolidated Financial Statements as “cost method businesses.” ICG’s share of the earnings and/or losses of cost method businesses is not included in ICG’s Consolidated Statement of Operations. However, impairment charges related to cost method businesses are recognized in ICG’s Consolidated Statements of Operations. If circumstances suggest that the value of a cost method business with respect to which an impairment charge has been made has subsequently recovered, that recovery is not recorded. The carrying values of ICG’s cost method businesses are reflected in the line item “Equity and cost method investments” in ICG’s Consolidated Balance Sheets.
	ICG initially records its carrying value in businesses accounted for under the cost method at cost, unless the equity securities of a cost method business have readily determinable fair values based on quoted market prices, in which case the interests are valued at fair value and are classified as marketable securities or some other classification in accordance with guidance for ownership interests in debt and equity securities.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Those estimates include evaluation of ICG’s convertible debt and equity holdings in businesses, holdings in marketable securities, asset impairment, revenue recognition, income taxes and commitments and contingencies. Those estimates and assumptions are based on management’s best judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, such as the current economic environment, that management believes to be reasonable under the circumstances. Management adjusts those estimates and assumptions when facts and circumstances dictate that it is necessary or appropriate to do so. It is reasonably possible that ICG’s accounting estimates with respect to the ultimate recoverability of ICG’s ownership interests in convertible debt and equity holdings, goodwill and the useful lives of intangible assets could change in the near term and that the effect of such changes on ICG’s consolidated financial statements could be material. Management believes the recorded amounts of goodwill, intangible assets, equity method businesses and cost method businesses were not impaired as of December 31, 2013.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	ICG considers all highly liquid instruments with an original maturity of approximately three months at the time of purchase to be cash equivalents. Cash and cash equivalents at December 31, 2013 and 2012 were invested principally in money market accounts and commercial paper.
Restricted Cash	'
	Restricted Cash
	ICG considers cash that is legally restricted and cash that is held as a compensative balance for letter of credit arrangements as restricted cash. ICG had no long-term restricted cash as of December 31, 2013 and 2012.
Goodwill, Intangible Assets, Equity Method Business and Cost Method Businesses	'
	Goodwill, Intangible Assets, Equity Method Businesses and Cost Method Businesses
	ICG evaluates its carrying value in equity method businesses and cost method businesses continuously to determine whether an other-than-temporary decline in the fair value of any such business exists and should be recognized. In order to make that determination, ICG considers each such business’ achievement of its business plan objectives and milestones, the fair value of its ownership interest in each such business (which, in the case of any company listed on a public stock exchange, is the quoted stock price of the relevant ownership interest), the financial condition and prospects of each such business, and other relevant factors. The business plan objectives and milestones ICG considers include, among others, those related to financial performance, such as achievement of planned financial results or completion of capital raising activities, and those that are not primarily financial in nature, such as obtaining key business partnerships or the hiring of key employees. Impairment charges are determined by comparing ICG’s carrying value of a business with its estimated fair value. Fair value is determined by using a combination of estimating the cash flows related to the relevant asset, including estimated proceeds on disposition, and an analysis of market price multiples of companies engaged in lines of business similar to the company being evaluated. ICG concluded that the carrying value of its equity method businesses and cost method businesses was not impaired as of December 31, 2013 and 2012.
	ICG tests goodwill for impairment annually during the fourth quarter of each year, or more frequently as conditions warrant, and tests intangible assets for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. ICG concluded that its goodwill and intangible assets were not impaired as of December 31, 2013 and 2012.
Marketable Securities	'
	Marketable Securities
	Marketable securities are reported at fair value, based on quoted market prices, with the net unrealized gain or loss reported as a component of “Accumulated Other Comprehensive Income” in ICG Group, Inc. Stockholders’ Equity on ICG’s Consolidated Statements of Changes in Equity.
Financial Instruments	'
	Financial Instruments
	Cash and cash equivalents, accounts receivable and accounts payable are carried at cost, which approximates fair value due to the short-term maturity of these instruments. Marketable securities are carried at fair value.
Deferred Revenue	'
	Deferred Revenue
	Deferred revenue consists primarily of payments received in advance of revenue being earned under the relevant customer agreements.
Revenue Recognition	'
	Revenue Recognition
	During the year ended December 31, 2013, ICG’s consolidated revenue was primarily attributable to Bolt, GovDelivery and MSDSonline. During the year ended December 31, 2012, ICG’s consolidated revenue was primarily attributable to GovDelivery and MSDSonline. During the year ended December 31, 2011, ICG’s consolidated revenue was attributable to GovDelivery.
	Bolt generates revenue from (1) software licenses, (2) maintenance and support services, (3) professional service fees, (4) insurance commissions and (5) subscription fees. Bolt’s software license revenue derives from licenses of its software products directly to end users and is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable; Bolt’s software license revenue is recognized ratably over the applicable contract term. Bolt’s maintenance and customer support fees are recognized ratably over the life of maintenance and support contracts, which is typically one year. Bolt’s professional service fees revenue relates to professional services for software licenses that require significant customization, integration and installation; that revenue is recognized ratably over the applicable contract term. Bolt’s commissions on the premiums from sales of insurance policies are recognized when Bolt has sufficient information to determine the amount that is owed, it is probable that the economic benefits associated with the transaction will flow to Bolt, and the costs incurred, or to be incurred, with respect to the transaction can be accurately measured. Finally, Bolt recognizes subscription fee revenue over the subscription period, which is generally one month.
	GovDelivery revenue consists of (1) nonrefundable setup fees and (2) monthly maintenance and hosting fees. Those fees generally are deferred and recognized as the services are performed, which is typically over the service term. Costs related to performing setup services are expensed as incurred.
	MSDSonline derives revenue from two sources: (1) subscription fees and (2) professional services fees. The vast majority of MSDSonline’s revenue is derived from subscription fees from customers accessing the business’ database and web-based tools; that revenue is recognized ratably over the applicable contract term, beginning on the contract implementation date. MSDSonline also generates professional services fees from (1) training, (2) authoring of material safety data sheets and (3) compiling customers’ online libraries of material safety data sheet documents and indexing those documents. The revenue derived from those fees is recognized on a percentage of completion basis over the applicable project’s timeline.
Equity-Based Compensation	'
	Equity-Based Compensation
	ICG recognizes equity-based compensation expense in the Consolidated Financial Statements for all share options and other equity-based arrangements that are expected to vest. Equity-based compensation expense is measured at the date of grant, based on the fair value of the aware, and is recognized using the straight-line method over the employee’s requisite service period. Equity-based awards with vesting conditions other than service are recognized based on the probability that those conditions will be achieved.
Research and Development	'
	Research and Development
	Research and development costs are charged to expense as incurred.
Income Taxes	'
	Income Taxes
	Income taxes are accounted for under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Discontinued Operations	'
	Discontinued Operations
	During the year ended December 31, 2013, Channel Intelligence, InvestorForce and Procurian were sold. Accordingly, ICG has recast all financial information within this Report to conform to the current period presentation; those three businesses are presented as discontinued operations for all periods presented.
Net Income (Loss) Per Share	'
	Net Income (Loss) Per Share
	Basic net income (loss) per share (EPS) is computed using the weighted average number of common shares outstanding during a given period. Diluted EPS includes shares, unless anti-dilutive, that would arise from the exercise of stock options and conversion of other convertible securities and is adjusted, if applicable, for the effect on net income (loss) of such transactions. See Note 15, “Net Income (Loss) per Share.”
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	ICG reports and displays comprehensive income (loss) and its components in the Consolidated Statements of Operations and Comprehensive Income (Loss). Comprehensive income (loss) is the change in equity of a business enterprise during a period from non-owner sources. ICG’s sources of comprehensive income (loss) are net income (loss), and net unrealized appreciation on its marketable securities. Reclassification adjustments result from the recognition of gains or losses in net income that were included in comprehensive income (loss) in prior periods.
Supplemental Cash Flow Disclosures	'
	Supplemental Cash Flow Disclosures
	In 2013, 2012 and 2011, ICG paid interest of $1.2 million, less than $0.1 million and $0.1 million, respectively. ICG made income tax payments of $0.3 million and $0.1 million in 2013 and 2012, respectively. ICG received income tax refunds of $6.5 million in 2011.
Escrow Information	'
	Escrow Information
	When an interest in one of ICG’s businesses is sold, a portion of the proceeds may be held in escrow primarily to satisfy purchase price adjustments and/or indemnity claims. ICG records gains on escrowed proceeds at the time ICG is entitled to receive such proceeds, the amount is fixed or determinable and realization is assured. As of December 31, 2013, $29.1 million related to ICG’s potential proceeds from sales of former businesses remained in escrow to satisfy potential or unresolved indemnification claims. Those outstanding escrows are scheduled to be released at various dates within the next two years, subject to pending and potential indemnity claims pursuant to the terms of the specific sales agreements. On January 15, 2014, $0.3 million related to the sale of StarCite was released from escrow. ICG will recognize a gain in that amount during the first quarter of 2014.
Concentration of Customer Base and Credit Risk	'
	Concentration of Customer Base and Credit Risk
	For the years ended December 31, 2013, 2012 and 2011, none of the customers of ICG’s consolidated businesses represented more than 10% of ICG’s consolidated revenue.
Commitments and Contingencies	'
	Commitments and Contingencies
	From time to time, ICG and its businesses are involved in various claims and legal actions arising in the ordinary course of business. ICG does not expect any liability with respect to any legal claims or actions that would materially affect its consolidated financial position or cash flows.
Reclassifications	'
	Reclassifications
	Certain amounts in the prior year financial statements have been reclassified to conform to the current-year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net income (loss).
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements

	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-02, “Other Comprehensive Income (Topic 220)” (“ASU 2013-02”). The objective of ASU 2013-02 is to improve the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 seeks to attain that objective by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. ASU 2013-02 was effective prospectively for ICG in its first quarter of 2013. The impact of the adoption of ASU 2013-02 was insignificant to the Consolidated Financial Statements.

	ICG has considered all other recently issued accounting pronouncements and does not believe the adoption of such pronouncements will have a material impact on its audited Financial Statements.
