Notes to Condensed Consolidated Financial Statements (unaudited)

(1) Organization and Basis of Presentation

Investment Technology Group, Inc. was formed as a Delaware corporation on July 22, 1983. Its principal subsidiaries include: (1) ITG Inc., AlterNet Securities, Inc. (“AlterNet”) and ITG Derivatives LLC (“ITG Derivatives”), United States (“U.S.”) broker-dealers, (2) ITG Canada Corp. (“ITG Canada”), a broker-dealer in Canada, (3) Investment Technology Group Limited, a broker-dealer in Europe, (4) ITG Australia Limited (“ITG Australia”), a broker-dealer in Australia, (5) ITG Hong Kong Limited (“ITG Hong Kong”), a broker-dealer in Hong Kong, (6) ITG Software Solutions, Inc., an intangible property, software development and maintenance subsidiary in the U.S., and (7) ITG Solutions Network, Inc., a holding company for ITG Analytics, Inc. (“ITG Analytics”), a provider of pre- and post-trade analysis, fair value and trade optimization services, The MacGregor Group, Inc. (“MacGregor”), a provider of trade order management technology and network connectivity services for the financial community and ITG Investment Research, Inc. (“ITG Investment Research”), a provider of independent data driven investment and market research.

ITG is an independent agency research broker that partners with asset managers globally to improve performance throughout the investment process. A leader in electronic trading since launching the POSIT crossing network in 1987, ITG takes a consultative approach in delivering the highest quality institutional liquidity, execution services, analytical tools and proprietary research insights grounded in data.  Asset managers rely on ITG’s independence, experience and intellectual capital to help mitigate risk, improve performance and navigate increasingly complex markets. The firm is headquartered in New York with offices in North America, Europe, and the Asia Pacific region.

The Company’s reportable operating segments are: U.S. Operations, Canadian Operations, European Operations and Asia Pacific Operations (see Note 16, Segment Reporting, to the consolidated financial statements, which also includes financial information about geographic areas). The U.S. Operations segment provides trade execution, trade order management, network connectivity and research services. The Canadian Operations segment provides trade execution, network connectivity and research services. The European Operations segment provides trade execution, trade order management, network connectivity and research services in Europe and includes a technology research and development facility in Israel.

The condensed consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”). All material intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for the fair presentation of results.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets, liabilities, revenues and expenses. Actual results could differ from those estimates.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with Securities and Exchange Commission (“SEC”) rules and regulations; however, management believes that the disclosures herein are adequate to make the information presented not misleading. This report should be read in conjunction with the audited financial statements and the notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

Recent Accounting Pronouncements

In September 2011, the FASB issued Accounting Standards Update (ASU) 2011-08, Intangibles — Goodwill and Other (Topic 350): Testing Goodwill for Impairment in an effort to simplify goodwill impairment testing.  The amendments permit companies to first assess qualitative factors to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350.  The more-likely-than-not threshold is defined as having a likelihood of more than 50%.  The amendments will be effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted.

In June 2011, the FASB issued ASU 2011-5, Comprehensive Income (Topic 220).  Companies will have two choices of how to present items of net income, items of comprehensive income and total comprehensive income.  Companies can create one continuous statement of comprehensive income or two separate consecutive statements and will be required to present reclassification

adjustments in both other comprehensive income and net income.  The guidance is effective for interim and annual periods beginning after December 15, 2011 with early adoption permitted.  The Company will apply the new presentation beginning in 2012.

The adoption of these standards is not expected to have a material impact on our consolidated results of operations or financial condition.

(2) Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, various methods are used including market, income and cost approaches. Based on these approaches, certain assumptions that market participants would use in pricing the asset or liability are used, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market-corroborated, or generally unobservable firm inputs. Valuation techniques that are used maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques, fair value measured financial instruments are categorized according to the fair value hierarchy prescribed by ASC 820, Fair Value Measurements and Disclosures. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:

·                  Level 1: Fair value measurements using unadjusted quoted market prices in active markets for identical, unrestricted assets or liabilities.

·                  Level 2: Fair value measurements using correlation with (directly or indirectly) observable market-based inputs, unobservable inputs that are corroborated by market data, or quoted prices in markets that are not active.

·                  Level 3: Fair value measurements using significant inputs that are not readily observable in the market.

Level 1 consists of financial instruments whose value is based on quoted market prices such as exchange-traded mutual funds and listed equities.

Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models are primarily standard models that consider various assumptions including time value, yield curve and other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Financial instruments in this category include non-exchange-traded derivatives such as currency forward contracts.

Level 3 is comprised of financial instruments whose fair value is estimated based on internally developed models or methodologies utilizing significant inputs that are generally less readily observable.

Fair value measurements for those items measured on a recurring basis are as follows (dollars in thousands):

Table of Contents

Cash and cash equivalents other than bank deposits are measured at fair value and include U.S. government money market mutual funds.

Securities owned, at fair value and securities sold, not yet purchased, at fair value includes common stocks, equity index mutual funds and bond mutual funds, all of which are exchange traded.

Currency forward contracts are valued based upon forward exchange rates and approximate the credit risk adjusted discounted net cash flow that would have been realized if the contracts had been sold at the balance sheet date.

Certain items are measured at fair value on a non-recurring basis. The table below details the portion of those items that were measured at fair value during the nine months ended September 30, 2011 and the resultant loss recorded (dollars in thousands):

Goodwill allocated to the Company’s U.S. Operations reporting unit with a carrying value of $470.1 million was written down to its implied fair value of $245.1 million resulting in an impairment charge of $225.0 million in the second quarter of 2011.

(3) Restructuring Charges

2011 Restructuring

In the second quarter of 2011, the Company decided to implement a restructuring plan to improve margins and enhance stockholder returns primarily focused on reducing workforce, consulting and infrastructure costs in the U.S. and Europe. The following table summarizes the pre-tax charges by segment (dollars in thousands).  Employee severance costs relate to the termination of approximately 100 employees and the lease consolidation costs relate to office space that was vacated. These charges are classified as restructuring charges in the Condensed Consolidated Statements of Operations.

10

Table of Contents

Most of the accrued costs are expected to be paid in 2011, except payments related to the vacated leased facilities, which will continue until March 2013, certain cash severance payments which will continue until August 2012 and the settlement of restricted share awards which will continue through February 2014.

Activity and liability balances recorded as part of the 2011 restructuring plan through September 30, 2011 are as follows:

Westchester Office Closing - 2010

In the fourth quarter of 2010, the Company decided to close its Westchester, NY office, relocate the staff, primarily sales traders and support, to its New York City office, and incurred a restructuring charge of $2.3 million.  The restructuring charge consisted of lease abandonment costs ($2.2 million) and employee severance costs ($0.1 million).

The following table summarizes the changes in the Company’s liability balance related to the Westchester office restructuring plan, which is included in accounts payable and accrued expenses in the Condensed Consolidated Statements of Financial Condition (dollars in thousands):

The remaining accrued costs related to employee separation are expected to be paid during 2011 while the payments related to the leased facilities will continue through 2016.

Asia Pacific Restructuring - 2010

In the second quarter of 2010, the Company implemented a plan to close its on-shore operations in Japan to lower costs and reduce capital requirements.  The annual expenses for the on-shore Japanese operations were approximately $4 million and the amount of regulatory capital deployed exceeded $20 million. In connection with this move, a one-time charge of $2.3 million was recorded for employee severance, contract termination costs and non-cash write-offs of fixed assets and capitalized software, which was partially offset in the fourth quarter of 2010 by $0.2 million for cumulative translation gains that were reclassified to operations following the substantial liquidation of the Japanese subsidiary.

The following table summarizes the changes in the Company’s liability balance related to the Asia Pacific restructuring plan, which is included in accounts payable and accrued expenses in the Condensed Consolidated Statements of Financial Condition (dollars in thousands):

2009 Restructuring

In the fourth quarter of 2009, the Company committed to a restructuring plan (aimed primarily at its U.S. Operations) to reengineer its operating model to focus on a leaner cost structure and a more selective deployment of resources towards those areas of our business that provide a sufficiently profitable return. As a result, a $25.4 million restructuring charge was recorded, which

11

Table of Contents

included costs related to employee separation, the consolidation of leased facilities and write-offs of capitalized software and certain intangible assets primarily due to changes in product priorities.  Employee separation and related costs pertain to the termination of 144 employees primarily from the U.S. Operations. The consolidation of leased facilities charges relate to non-cancelable leases which were vacated.

The following table summarizes the changes in the Company’s liability balance related to the 2009 restructuring plan included in accounts payable and accrued expenses in the Consolidated Statements of Financial Condition (dollars in thousands):

The remaining accrued costs relate to payments related to the leased facilities and the settlement of restricted share awards which will continue through April 2012.

(4) Derivative Instruments

Derivative Contracts

All derivative instruments are recorded on the Condensed Consolidated Statements of Financial Condition at fair value in other assets or accounts payable and accrued expenses. Recognition of the gain or loss that results from recording and adjusting a derivative to fair value depends on the intended purpose for entering into the derivative contract. Gains and losses from derivatives that are not accounted for as hedges under ASC 815, Derivatives and Hedging, are recognized immediately in income. For derivative instruments that are designated and qualify as a fair value hedge, the gains or losses from adjusting the derivative to its fair value will be immediately recognized in income and, to the extent the hedge is effective, offset the concurrent recognition of changes in the fair value of the hedged item. Gains or losses from derivative instruments that are designated and qualify as a cash flow hedge will be recorded on the Consolidated Statements of Financial Condition in accumulated other comprehensive income (“OCI”) until the hedged transaction is recognized in income. However, to the extent the hedge is deemed ineffective, the ineffective portion of the change in fair value of the derivative will be recognized immediately in income. For discontinued cash flow hedges, prospective changes in the fair value of the derivative are recognized in income. Any gain or loss in accumulated OCI at the time the hedge is discontinued will continue to be deferred until the original forecasted transaction occurs. However, if it is determined that the likelihood of the original forecasted transaction is no longer probable, the entire related gain or loss in accumulated OCI is immediately reclassified into income.

Economic Hedges

The Company enters into three month forward contracts to sell Euros and buy British Pounds to economically hedge against the risk of currency movements on Euro deposits held in banks across Europe for equity trade settlement. When a contract matures, an assessment is made as to whether or not the contract value needs to be amended prior to entering into another, to ensure continued economic hedge effectiveness. As these contracts are not designated as hedges, the changes to their fair value are recognized immediately in income. The related counterparty agreements do not contain any credit-risk related contingent features. There were no open three month forward contracts outstanding at September 30, 2011.

When clients request trade settlement in a currency other than the currency in which the trade was executed, the Company enters into foreign exchange contracts in order to close out the resulting foreign currency position. The foreign exchange deals are executed the same day as the underlying equity trade.  As these contracts are not designated as hedges, the changes to their fair value are recognized immediately in income. These foreign exchange contracts are reflected in the tables below.

Fair Values and Effects of Derivatives Held

Asset derivatives are included in other assets while liability derivatives are included in accounts payable and accrued expenses on the Condensed Consolidated Statements of Financial Condition.  The following table summarizes the fair values of our derivative instruments at September 30, 2011 and December 31, 2010 (dollars in thousands).  There were no derivatives designated as hedging instruments in either period.

12

Table of Contents

The following table summarizes the impact that derivative instruments not designated as hedging instruments under ASC 815 had on the results of operations for the three and nine month periods ended September 30, which are recorded in other general and administrative expense in the Condensed Consolidated Statements of Operations (dollars in thousands).

(5) Cash Restricted or Segregated Under Regulations and Other

Cash restricted or segregated under regulations and other represents (i) funds on deposit for the purpose of securing working capital facilities for clearing and settlement activities in Hong Kong, (ii) a special reserve bank account for the exclusive benefit of customers and brokers (“Special Reserve Bank Account”) maintained by ITG Inc. in accordance with Rule 15c3-3 of the Exchange Act (“Customer Protection Rule”), (iii) funds relating to the collateralization of a letter of credit and a bank guarantee supporting two MacGregor leases, (iv) funds on deposit for European trade clearing and settlement activity, (v) segregated balances under a collateral account control agreement for the benefit of certain customers, (vi) funds relating to the securitization of bank guarantees supporting Australian and Israeli leases and (vii) funds relating to the securitization of a letter of credit supporting an ITG Investment Research lease.

(6) Securities Owned and Sold, Not Yet Purchased

The following is a summary of securities owned and securities sold, not yet purchased (dollars in thousands):

Trading securities owned and sold, not yet purchased primarily consists of temporary positions obtained in the normal course of agency trading activities, including positions held in connection with the creation and redemption of exchange-traded funds on behalf of clients.

Available-for-Sale Securities

Unrealized holding gains and losses on available-for-sale securities, net of tax effects, which are reported in accumulated other comprehensive income until realized, are as follows (dollars in thousands):

13

Table of Contents

Unrealized holding gains on securities, available-for-sale as of December 31, 2010 relates to shares of NYSE Euronext, Inc. the Company received as part of the merger of the New York Stock Exchange and Archipelago Holdings Inc. on March 9, 2006.  During the first quarter of 2011, the Company sold all of the available-for-sale securities it held for gross proceeds of $2.1 million and recorded a pre-tax gain of $0.5 million in other revenues.  There were no sales of available-for-sale securities during the nine month period ending September 30, 2010.

(7) Income Taxes

The tax benefit from an uncertain tax position is recognized only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution.

During the nine months ended September 30, 2010, uncertain tax positions in the U.S. were resolved for the 2006 and 2008 fiscal years resulting in a decrease in our tax liability of $1.7 million and the related deferred tax asset of $0.3 million.  As a result of this, we recognized a net tax benefit of $0.9 million.

During the nine months ended September 30, 2011, no uncertain tax positions in the U.S. were resolved.

The Company had unrecognized tax benefits for tax positions taken of $13.6 million and $12.4 million at September 30, 2011 and December 31, 2010, respectively.  The Company had accrued interest expense of $1.5 million and $1.2 million, net of related tax effects, related to unrecognized tax benefits at September 30, 2011 and December 31, 2010, respectively.

(8) Acquisitions

Ross Smith Energy Group Ltd.

On June 3, 2011, the Company completed its acquisition of Ross Smith Energy Group Ltd. (“RSEG”), a Calgary-based independent provider of research on the oil and gas industry. RSEG provides detailed technical and financial analysis of North American resource plays, public and private corporations, as well as coverage of international and macroeconomic energy issues, for more than 200 clients in North America and Europe, a number of which are new clients for ITG. The acquisition of RSEG expands the ITG Investment Research platform to include differentiated views into the exploration and production activities of North American and international energy companies.

The results of RSEG have been included in the Company’s condensed consolidated financial statements since its acquisition date. The $38.6 million purchase price for RSEG consists of all cash with no contingent payment provisions. In connection with the acquisition, the Company also incurred approximately $0.7 million of acquisition related costs, including legal fees and other professional fees, as well as $1.8 million in connection with the termination of a distribution agreement with a third party, net of a $1.0 million recovery from RSEG’s former owners.  These costs were classified in the Condensed Consolidated Statements of Operations as acquisition related costs.

The assets and liabilities of RSEG were recorded as of the acquisition date, at their respective fair values, under business combination accounting. The purchase price allocation is based on estimates of the fair value of assets acquired and liabilities assumed as follows (dollars in thousands):

14

Table of Contents

The goodwill and customer related intangible asset were assigned to the U.S. Operations segment, which is expected to be the primary beneficiary of the synergies achieved from the business combination. The goodwill is deductible for tax purposes over 15 years. The acquired customer related intangible asset of $7.0 million has a 10 year useful life. The pro forma results of the RSEG acquisition would not have been material to the Company’s result of operations.

(9) Goodwill and Other Intangibles

The following table presents the changes in the carrying amount of goodwill by reportable segment for the period ended September 30, 2011 (dollars in thousands):
