NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.                 Basis of Presentation

thinkorswim Group Inc., a leading provider of online brokerage and investor education services completed the conversion of its corporate identity from Investools Inc. on June 6, 2008. The Condensed Consolidated Financial Statements include the accounts of thinkorswim Group Inc. and its wholly-owned subsidiaries (the “Company” or “thinkorswim”). All intercompany balances and transactions have been eliminated in consolidation.

The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2007 included in the Company’s Annual Report on Form 10-K.

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (“SEC”) and do not include all the information and footnotes required by accounting principles generally accepted in the United States. However, in the opinion of management, the information furnished reflects all adjustments, consisting of normal recurring adjustments, which are necessary to make a fair presentation of financial position and operating results for the interim periods. The results of operations for the three and nine month periods ended September 30, 2008 are not necessarily indicative of the results to be expected for the full year.

2.                 Summary of Significant Accounting Policies

Use of Estimates

Preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosed amounts of contingent assets and liabilities and the reported amounts of revenues and expenses. Management believes the most significant estimates and assumptions are associated with the valuation of intangibles, goodwill, income taxes, and revenue recognition. If the underlying estimates and assumptions, upon which the financial statements are based, change in future periods, actual amounts may differ from those included in the accompanying Condensed Consolidated Financial Statements.

Except as described in the following paragraphs, there have been no changes in significant accounting policies from those included in the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2007.

Reclassifications

Certain prior period amounts in the Condensed Consolidated Financial Statements have been reclassified to conform to the current period’s presentation. In the Condensed Consolidated Statements of Income for the nine months ended September 30, 2008, $1.1 million of trade errors and customer debit write-offs were reclassified from General and Administrative expense to Cost of Revenue related to the six month period ended June 30, 2008. In addition, for the three and nine months ended September 30, 2007, $0.2 and $0.3 million were reclassified from General and Administrative expense to Cost of Revenue in the Condensed Consolidated Statements of Income

Fair Value Measurements

In February 2007, the FASB issued Statement No. 159, Fair Value Option for Financial Assets and Financial Liabilities — Including an amendment of FASB Statement No. 115 (“FAS 159”). This Statement permits entities to choose to measure selected financial assets and liabilities at fair value and report unrealized gains and losses on these instruments in earnings. FAS 159 was effective January 1, 2008. The Company did not elect the fair value option. The Company’s adoption of FAS 159 did not have a material impact on its results of operations or financial position.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Deferred income taxes are recognized by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax carryforwards. 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. The measurement of deferred tax assets

6

Table of Contents

is reduced, if necessary, by a valuation allowance for any tax benefits for which future realization is uncertain. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

The Company has utilized an estimated effective annual tax rate for interim reporting for the three and nine month periods ended September 30, 2008. Under this method generally accepted accounting principles require that the interim period tax provision be determined as follows:

·                  At the end of each quarter, the Company estimates the tax that will be provided for the fiscal year stated as a percentage of estimated “ordinary” income for the fiscal year. The term ordinary income refers to income from continuing operations before income taxes, excluding significant unusual or infrequently occurring items.

·                  The estimated annual effective tax rate is applied to the year-to-date “ordinary” income at the end of each quarter to compute the year-to-date tax applicable to ordinary income. The tax expense or benefit related to ordinary income in each quarter is the difference between the most recent year-to-date and the prior quarter year-to-date computations.

·                  The tax effects of significant unusual or infrequently occurring items are recognized as discrete items in the interim period in which the event occurs.

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income of the Company in each tax jurisdiction in which it operates and the development of tax planning strategies during the year. In addition, the Company’s tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews, as well as other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax positions.

Accounting Pronouncements Issued Not Yet Adopted

On January 1, 2008, the Company adopted certain provisions of Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards (“SFAS”) No. 157, Fair Value Measurements (“FAS 157”), which establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and expands on required disclosures about fair value measurement. The provisions of FAS 157 adopted on January 1, 2008 relate to financial assets and liabilities as well as other assets and liabilities carried at fair value on a recurring basis and did not have a material impact on the Company’s Condensed Consolidated Financial Statements. The provisions of FAS 157 related to other nonfinancial assets and liabilities will be effective for the Company on January 1, 2009, and will be applied prospectively. The Company is currently evaluating the impact that these additional FAS 157 provisions will have on the Company’s Consolidated Financial Statements.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007), “Business Combinations”. This standard establishes that an acquiring entity will be required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition-date fair value with limited exceptions. This standard also defines how goodwill acquired in a business combination or a gain from a bargain purchase should be recognized and updates certain disclosure requirements for business combinations. This standard applies prospectively to business combinations for which the acquisition date is on or after the fiscal year beginning after December 15, 2008.

In March 2008, the FASB issued SFAS No. 161, “ Disclosure about Derivative Instruments and Hedging Activities, an Amendment of FASB Statement No. 133”  (“SFAS No. 161”). SFAS No. 161 is intended to improve transparency in financial reporting by requiring enhanced disclosures of an entity’s derivative instruments and hedging activities and their effects on the entity’s financial position, financial performance, and cash flows. SFAS No. 161 applies to all derivative instruments within the scope of SFAS No. 133. It also applies to non-derivative hedging instruments and all hedged items designated and qualifying as hedges under SFAS No. 133. SFAS No. 161 amends the current qualitative and quantitative disclosure requirements for derivative instruments and hedging activities set forth in SFAS No. 133 and generally increases the level of disaggregation that will be required in an entity’s financial statements. SFAS No. 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk related contingent features in derivative agreements. SFAS No. 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The Company is currently evaluating the impact that SFAS 161 will have on our consolidated financial statements.

In April 2008, the FASB issued FASB Staff Position FAS 142-3, “Determination of Useful Life of Intangible Assets” (“FSP 142-3”). FSP 142-3 amends the factors that should be considered in developing the renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FAS 142, “Goodwill and Other Intangible Assets.” FSP 142-3 also requires expanded disclosure regarding the determination of intangible asset useful lives. FSP 142-3 is effective for fiscal years beginning after

7

Table of Contents

December 15, 2008. Earlier adoption is not permitted. We are currently evaluating the potential impact the adoption of FSP 142-3 will have on our consolidated financial statements.

In May 2008, the FASB issued Statement No. 162, The Hierarchy of Generally Accepted Accounting Principles (FAS 162). FAS 162 identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements that are presented in conformity with generally accepted accounting principles in the United States. FAS 162 is effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, “The Meaning of ‘Present fairly in conformity with generally accepted accounting principles’”. FAS 162 is not expected to have a material impact on our financial statements.

3.                 Acquisitions

thinkorswim Holdings, Inc.

In September 2006, the Company and thinkorswim Holdings, Inc. (“thinkorswim Holdings”), prior to June 6, 2008 known as thinkorswim Group Inc., a Delaware corporation, entered into an Agreement and Plan of Merger pursuant to which the Company would acquire 100% of the outstanding stock of thinkorswim Holdings. On February 15, 2007, the Company’s wholly-owned subsidiary, Atomic Acquisition Corp., merged with and into thinkorswim Holdings, and the results of thinkorswim Holdings’ operations have been included in the Condensed Consolidated Financial Statements since that date. The total purchase price of $360.9 million included cash of $182.8 million, shares of common stock worth $167.1 million (19.1 million shares of common stock), and $11.0 million in direct acquisition costs. In connection with the merger, JPMorgan Chase Bank, N.A. and J.P. Morgan Securities Inc. provided the Company a senior secured term loan of $125.0 million to fund a portion of the cash purchase price.

As part of the Merger Agreement, the Company agreed to issue up to a maximum of 728,608 additional shares of common stock to thinkorswim Holdings shareholders in the event the stock’s average trading price fell below $8.75 per share during the twenty-day period prior to certain dates subsequent to the Merger (with an $8.00 floor on such share price). No such additional shares have been issued as of September 30, 2008. Of the remaining additional shares that may be issuable under the Merger Agreement, up to a maximum of 117,586 and 100,788 shares could be issuable as of February 15, 2009 and February 15, 2010, respectively (or, in each case, such later date when a shelf registration statement is first effective for the shares that become freely transferable as of such date) if the trading price falls below $8.75 as described above prior to such dates. At the time the Merger was announced, the fair market value of the Company’s stock was $8.59. Because the additional shares are contingently issuable if the price falls below $8.75 per share, the value of the portion of the purchase price attributable to the issuance of common stock has been increased to $8.75 per share in accordance with EITF No. 97-15, “Accounting for Contingency Arrangements Based on Security Prices in a Purchase Business Combination ”.

The purchase price has been allocated to tangible and intangible assets acquired and liabilities assumed based on their respective fair values. The excess purchase price over the fair value of tangible and intangible assets and liabilities assumed was recorded as goodwill. The fair values of intangible assets were based upon cash flow analysis and other market considerations of identifiable intangible assets acquired, including useful lives. The following table summarizes the allocation of the purchase consideration (in thousands) and the estimated amortization period for the acquired intangibles:

Table of Contents

The goodwill that was recorded in this acquisition is associated with the Brokerage Services segment. None of the recorded goodwill is tax deductible. Of the total value assigned to intangible assets, $16.1 million was allocated to trade names, which are not subject to amortization.

In connection with the merger with thinkorswim Holdings, certain employees and consultants of thinkorswim Holdings have the opportunity to participate in a retention bonus pool which equals, in the aggregate, $20 million conditioned upon continued employment. The bonus pool does not extend to Messrs. Sosnoff, President, thinkorswim Holdings, Inc. and Sheridan, Executive Vice President, thinkorswim Holdings, Inc. The bonuses will be paid in equal annual installments over the three-year period following the closing of the Merger. Such amounts are being expensed on a straight-line basis over the retention period of three years. The first payments, totaling approximately $6.5 million were made in the quarter ending March 31, 2008. The accrual for retention bonuses is included in the Condensed Consolidated Balance Sheets within accrued payroll.

In addition, the Company granted certain employees and consultants of thinkorswim Holdings options to purchase 2,255,563 shares of Common Stock which vest over four years, under the Company’s 2001 Stock Option Plan, half with an exercise price equal to the fair market value of the underlying Common Stock at the time of grant, and half with an exercise price equal to 150% of such fair market value. Approximately 125,000 of these stock options were granted to consultants to thinkorswim Holdings. We have accounted for stock options granted to consultants in accordance with EITF No. 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring or in Conjunction with Selling Goods or Services.”

At the time of the acquisition, approximately $8.5 million was placed in escrow pending the resolution of various contingencies and tax-related matters. When the resolution of these contingencies is determinable beyond a reasonable doubt, this amount will be recorded as goodwill. Subsequent to the merger date cash payments and deductions made from funds held in escrow totaled $1.1 million as of September 30, 2008 and are included in the total purchase price. The remaining escrow balance related to these contingencies was $7.4 million as of September 30, 2008.

Additionally, in November 2007, the Company received a refund of approximately $8.5 million related to carryback claims generated by stock option exercises of pre-merger thinkorswim Holdings shareholders. This amount was recorded as an income tax receivable and as a corresponding payable at the time of the merger representing the funds due to former pre-merger thinkorswim Holdings shareholders. The refund was placed in escrow upon receipt. The refund is currently under audit by the Internal Revenue Service (“IRS”). Upon completion of the IRS audit the escrow funds will be paid to the pre-merger thinkorswim Holdings shareholders less any claims paid to the IRS, if any. The escrow amounts of $15.9 million as of September 30, 2008 are included in the Condensed Consolidated Balance Sheets within Other long-term assets.

The following table contains unaudited and pro forma results of operations for the nine month period ended September 30, 2007. The pro forma results of operations give pro forma effect as if the thinkorswim Holdings merger had occurred on January 1, 2007, after giving effect to certain adjustments including the amortization of the intangible assets, interest expense, tax adjustments, and assumes the purchase price has been allocated to the assets purchased and the liabilities assumed based on their values at the date of purchase. The effect of the change in fair value of the interest rate swap (See Note 4) has not been included in the following pro forma results of operations. The following unaudited pro forma results of operations are presented for illustrative purposes only, and are not necessarily indicative of the operating results that would have occurred had the transaction been consummated for the dates indicated. Furthermore, such unaudited pro forma results of operations are not necessarily indicative of future operating results of the combined companies, due to changes in operating activities following the purchase, and should not be construed as representative of the operating results of the combined companies for any future dates or periods.

4.                 Fair Value Measurements

Effective January 1, 2008, the Company adopted FAS 157, Fair Value Measurements, for all financial assets and liabilities and non-financial assets and liabilities accounted for at fair value on a recurring basis. FAS 157 establishes a new framework for measuring fair value and expands related disclosures. Broadly, the FAS 157 framework requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for

9

Table of Contents

the asset or liability in an orderly transaction between market participants. FAS 157 establishes market or observable inputs as the preferred source of values, followed by assumptions based on hypothetical transactions in the absence of market inputs.

The valuation techniques required by FAS 157 are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 Quoted prices for identical instruments in active markets.

Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Significant inputs to the valuation model are unobservable.

The following table presents information about assets and liabilities required to be carried at fair value on a recurring basis as of September 30, 2008 (in thousands):

(1)             Securities owned are included in Other current assets on the Condensed Consolidated Balance Sheet.

(2)             Securities sold, not yet purchased are included in Other current liabilities on the Condensed Consolidated Balance Sheet.

(3)             Interest Rate Swap is included in Other long-term accrued liabilities on the Condensed Consolidated Balance Sheet.

The Company primarily applies the market approach for recurring fair value measurements. In addition, the Company uses the income approach with significant observable market inputs to value the Company’s interest rate swap.

For the three and nine months ended September 30, 2008, the company recorded $0.2 million loss and $0.1 million gain from change in fair value of the swap, respectively. For the three and nine months ended September 30, 2007 the company recorded $1.0 million and $0.5 million losses from change in fair value of the swap, respectively. These amounts were classified into interest expense as a yield adjustment to that portion of the term loans designated as a hedged debt obligation. The Company’s adoption of FAS 157 had no impact on net income and no impact on earnings per share.

5.                 Capitalized Software Development Costs

The Company complies with the American Institute of Certified Public Accountants (“AICPA”) Statement of Position (“SOP”) No. 98-1, “Accounting For Costs of Computer Software Developed or Obtained for Internal Use,” and EITF No. 00-2, “Accounting for Website Development Costs”  when accounting for internal use software . In accordance with SOP 98-1, software development costs incurred as part of an approved project plan that result in additional functionality to internal use software are capitalized and amortized on a straight-line basis over the estimated useful life of the software. The Company capitalized $1.3 million and $3.5 million during the three and nine months ended September 30, 2008, respectively, and $4.4 million and $13.3 million for the three and nine months ended September 30, 2007, respectively, of software development costs related to internal use software for the implementation of the Company’s integrated enterprise resource planning and customer relationship management software solution and software and website assets developed for internal use by the brokerage services segment.

Amortization of software developed for internal use begins when the internal use software is ready for its intended use. The integrated enterprise resource planning software was placed in service in March 2007. The customer relationship management software was placed in service in December 2007, except for certain functionality that will be placed in service when completed in 2008. Internally developed software and website assets developed for internal use by the brokerage services segment have been placed in service on various dates during 2007 and 2008. Amortization expense was approximately $1.4 million and $3.8 million during the three and nine months ended September 30, 2008, respectively, and $0.6 million and $2.3 million for the three and nine months ended September 30, 2007, respectively.

6.                 Securities Owned and Securities Sold, Not Yet Purchased

Securities owned and securities sold, not yet purchased, are carried at market value and recorded on a trade date basis. The Company does not actively trade securities for its own benefit. Securities sold, not yet purchased represent obligations of the Company to make future delivery of specified securities and correspondingly create an obligation to purchase securities at prevailing market prices. Equities and options included in securities owned and securities sold, not yet purchased generally result from trade corrections.

 Securities owned and securities sold, not yet purchased, are composed of the following (in thousands):

Securities owned and securities sold, not yet purchased are included in Other current assets and Other current liabilities, respectively, within the Condensed Consolidated Balance Sheets.

7.             Acquired Intangibles and Goodwill

Amortizable Intangibles

8.                 Stock-Based Compensation

The Company’s purpose of granting stock options is to attract, retain, motivate and reward officers, directors and employees of the Company.

Employee Stock Option Plan Activity

The following table represents stock option activity for the nine months ended September 30, 2008:

At September 30, 2008, the aggregate intrinsic value of options outstanding was $17.1 million and the aggregate intrinsic value of exercisable options was $16.0 million. The total intrinsic value of options exercised was $5.4 million and $7.2 million for the three and nine months ended September 30, 2008, respectively, and $0.3 million and $1.6 million for the three and nine months ending September 30, 2007, respectively.

At September 30, 2008, there was $14.6 million of unrecognized compensation cost related to options which is expected to be recognized over a weighted-average period of 2.5 years.

The total compensation expense related to the Company’s stock option plans, which is included in results of operations within the Condensed Consolidated Statements of Income, was $1.5 million and $4.7 million for the three and nine months ended September 30, 2008, respectively, and $1.6 million and $12.6 million for the three and nine month periods ended September 30, 2007, respectively. Of the expense during the nine months ended September 30, 2007, $8.5 million relates to a grant to the Company’s chief executive which terms were modified.

The Company uses the Black-Scholes option pricing model to estimate the fair value of option awards with the following weighted average assumptions for the periods indicated:

12

Table of Contents

On April 25, 2008 the Compensation Committee approved and the Board ratified, an amendment to the 2001 Stock Option Plan to make mandatory, instead of permissive, adjustments in the number of shares awarded and the number of shares available for award under the 2001 Stock Option Plan in the event of a reorganization, merger, consolidation, reclassification, recapitalization, combination or exchange of share, stock split, stock dividend, rights offering, or other similar transaction or event occurs of or by the Company.

For the three and nine month periods ended September 30, 2008, the Company repurchased and retired 0.1 million shares of common stock for a total cost of $1.5 million or $9.72 per share, under the terms of the program. The price of the shares was the closing market price on the date of repurchase.  At September 30, 2008, 4,850,209 shares may be repurchased under the stock repurchase plan.

Restricted Stock

On June 6, 2008, the shareholders approved an amendment to the 2004 restricted stock plan increasing the amount of common stock available for issuance under the plan from 500,000 to 1,500,000. There are 1,122,075 shares of Company common stock available for issuance under the 2004 Restricted Stock Plan as of September 30, 2008, as amended. Shares of Company common stock awarded under the plan may be either previously authorized but unissued shares or issued shares which have been reacquired by the Company after their original issuance (including but not limited to shares purchased on the open market).

A summary of the status of the Company’s non-vested shares as of September 30, 2008, and changes during the nine months ended September 30, 2008, is as follows:

As of September 30, 2008, there was $2.2 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the 2004 Plan. The expense is expected to be recognized over a weighted-average period of 1.6 years. The compensation cost related to restricted stock issued under the 2004 Plan and included in operating expenses within the Condensed Consolidated Statements of Income was $0.5 million and $1.6 million for the three and nine months ended September 30, 2008, respectively, and $0.3 million and $0.8 million for the three and nine months ended September 30, 2007, respectively. The fair value of the restricted stock awards is recognized in compensation expense as the restrictions lapse over their respective vesting periods based on their fair value on the date of grant.

The total fair value of shares vested during the three and nine months ended September 30, 2008 and 2007 was $5,245 and $1.2 million and $0 and $47,070, respectively.

In conjunction with the vesting of restricted stock, several individuals elected to pay the taxes on the vested shares by allowing the Company to withhold some of the shares to cover the amount of required minimum tax withholdings. For the three month period ended September 30, 2008, the Company withheld no shares and for the nine month period ended September 30, 2008 the Company withheld 26,482 shares worth $0.4 million or $16.27 per share. The price of the shares was the closing market price on the date repurchased.

9.                 Net Income Per Share

Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive common stock equivalents outstanding during the period. Potential common stock equivalents amounting to 2.9 million and 2.8 million for the three and nine months ended September 30, 2008, respectively, and 2.5 million and 2.4 million for the three and nine months ended September 30, 2007, respectively, are excluded from the computation because their effect is anti-dilutive.

The aggregate maturities of notes payable were as follows as of September 30, 2008 (in thousands):

The Company incurred approximately $4.5 million of debt issuance costs related to these notes payable during the first quarter of 2007. The debt issuance costs are being amortized using the effective interest rate method over the notes payable term. Amortization expense was $0.2 million and $0.8 million for the three and nine months ended September 30, 2008, respectively, and $0.3 million and $0.8 million for the three and nine months ended September 30, 2007, respectively.
