Table of Contents

Our calculations of assets under management and fee-earning assets under management may differ from the calculations of other asset managers, and as a result this measure may not be comparable to similar measures presented by other asset managers. In addition, our calculation of assets under management includes commitments to, and the fair value of, invested capital in our funds from Blackstone and our personnel, regardless of whether such commitments or invested capital are subject to fees. Our definitions of assets under management or fee-earning assets under management are not based on any definition of assets under management or fee-earning assets under management that is set forth in the agreements governing the investment funds that we manage.

For our carry funds, total assets under management includes the fair value of the investments held, whereas fee-earning assets under management includes the amount of capital commitments or the remaining amount of invested capital at cost, depending on whether the investment period has or has not expired. As such, fee-earning assets under management may be greater than total assets under management when the aggregate fair value of the remaining investments is less than the cost of those investments.

The Blackstone Group L.P., together with its subsidiaries, (“Blackstone” or the “Partnership”) is a leading global manager of private capital and provider of financial advisory services. The alternative asset management business includes the management of private equity funds, real estate funds, funds of hedge funds, credit-oriented funds, separately managed accounts and publicly traded closed-end mutual funds (collectively referred to as the “Blackstone Funds”). Blackstone also provides various financial advisory services, including financial advisory, restructuring and reorganization advisory and fund placement services. Blackstone’s business is organized into four segments: private equity; real estate; credit and marketable alternatives; and financial advisory.

The Partnership was formed as a Delaware limited partnership on March 12, 2007. The Partnership is managed and operated by its general partner, Blackstone Group Management L.L.C., which is in turn wholly-owned and controlled by one of Blackstone’s founders, Stephen A. Schwarzman (the “Founder”), and Blackstone’s other senior managing directors.

The activities of the Partnership are conducted through its holding partnerships: Blackstone Holdings I L.P.; Blackstone Holdings II L.P.; Blackstone Holdings III L.P. and Blackstone Holdings IV L.P. (collectively, “Blackstone Holdings”, “Blackstone Holdings Partnerships” or the “Holding Partnerships”). On June 18, 2007, in preparation for an initial public offering (“IPO”), the predecessor owners (“Predecessor Owners”) of the Blackstone business completed a reorganization (the “Reorganization”) whereby, with certain limited exceptions, the operating entities of the predecessor organization and the intellectual property rights associated with the Blackstone name were contributed (“Contributed Businesses”) to five holding partnerships (Blackstone Holdings I L.P., Blackstone Holdings II L.P., Blackstone Holdings III L.P., Blackstone Holdings IV L.P. and Blackstone Holdings V L.P.) either directly or indirectly via a sale to certain wholly-owned subsidiaries of the Partnership and then a contribution to the Holding Partnerships. The Partnership, through its wholly-owned subsidiaries, is the sole general partner in each of these Holding Partnerships. The reorganization was accounted for as an exchange of entities under common control for the component of interests contributed by the Founders and the other senior managing directors (collectively, the “Control Group”) and as an acquisition of non-controlling interests using the purchase method of accounting for all the predecessor owners other than the Control Group.

On January 1, 2009, the number of Holding Partnerships was reduced from five to four through the transfer of assets and liabilities of Blackstone Holdings III L.P. to Blackstone Holdings IV L.P. In connection therewith, Blackstone Holdings IV L.P. was renamed Blackstone Holdings III L.P. and Blackstone Holdings V L.P. was renamed Blackstone Holdings IV L.P. Blackstone Holdings refers to the five holding partnerships prior to the January 2009 reorganization and the four holding partnerships subsequent to the January 2009 reorganization.

Holders of the limited partner interests in the four Holding Partnerships may, up to four times each year, exchange their limited partnership interests (“Partnership Units”) for Blackstone Common Units, on a one-to-one basis, exchanging one Partnership Unit in each of the four Holding Partnerships for one Blackstone Common Unit.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Partnership have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q. The condensed consolidated financial statements, including these notes, are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting of only normal recurring items) so that the condensed consolidated financial statements are presented fairly and that estimates made in

9

Notes to Condensed Consolidated Financial Statements—(Continued)

preparing its condensed consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Partnership’s Annual Report on Form 10-K filed with the Securities and Exchange Commission.

The condensed consolidated financial statements include the accounts of the Partnership, its wholly-owned or majority-owned subsidiaries, the consolidated entities which are considered to be variable interest entities and for which the Partnership is considered the primary beneficiary, and certain partnerships or similar entities which are not considered variable interest entities but in which the Partnership has a controlling financial interest.

All intercompany balances and transactions have been eliminated in consolidation.

Certain reclassifications have been made to prior year amounts to conform to the current year presentation as follows:

Consolidation

The Partnership consolidates all entities that it controls through a majority voting interest or otherwise, including those Blackstone Funds in which the general partner is presumed to have control. Although the Partnership has a non-controlling interest in the Blackstone Holdings Partnerships, the limited partners do not have the right to dissolve the partnerships or have substantive kick out rights or participating rights that would overcome the presumption of control by the Partnership. Accordingly, the Partnership consolidates Blackstone Holdings and records non-controlling interests to reflect the economic interests of the limited partners of Blackstone Holdings.

In addition, the Partnership consolidates all variable interest entities (“VIE”) in which it is the primary beneficiary. An enterprise is determined to be the primary beneficiary if it holds a controlling financial interest. A controlling financial interest is defined as (a) the power to direct the activities of a variable interest entity that most significantly impact the entity’s business and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the variable interest entity. The revised consolidation rules require an analysis to (a) determine whether an entity in which the Partnership holds a variable interest is a variable interest entity and (b) whether the Partnership’s involvement, through holding interests directly or indirectly in the entity or contractually through other variable interests (e.g., management and performance related fees), would give it a controlling financial interest. Performance of that analysis requires the exercise of judgment. Where the variable interest entities have qualified for the deferral of the revised consolidation rules as discussed in “Recent Accounting Developments”, the analysis is based on previous consolidation rules. These rules require an analysis to (a) determine whether an entity in which the Partnership holds a variable interest is a variable interest entity and (b) whether the Partnership’s involvement, through holding interests directly or indirectly in the entity or contractually through other variable interests (e.g., management and performance related fees), would be expected to absorb a majority of the variability of the entity. Under both guidelines, the Partnership determines whether it is the primary beneficiary of a VIE at the

10

Notes to Condensed Consolidated Financial Statements—(Continued)

(All Dollars Are in Thousands, Except Unit and Per Unit Data, Except Where Noted)

time it becomes involved with a variable interest entity and reconsiders that conclusion continuously. In evaluating whether the Partnership is the primary beneficiary, Blackstone evaluates its economic interests in the entity held either directly by the Partnership or indirectly through employees. The consolidation analysis can generally be performed qualitatively; however, if it is not readily apparent that the Partnership is not the primary beneficiary, a quantitative analysis may also be performed. Investments and redemptions (either by the Partnership, affiliates of the Partnership or third parties) or amendments to the governing documents of the respective Blackstone Funds could affect an entity’s status as a VIE or the determination of the primary beneficiary. At each reporting date, the Partnership assesses whether it is the primary beneficiary and will consolidate or deconsolidate accordingly.

Blackstone’s other disclosures regarding VIEs are discussed in Note 9. “Variable Interest Entities”.

Fair Value of Financial Instruments

GAAP establishes a hierarchal disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value.

Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows:

11

Table of Contents

THE BLACKSTONE GROUP L.P.

Notes to Condensed Consolidated Financial Statements—(Continued)

(All Dollars Are in Thousands, Except Unit and Per Unit Data, Except Where Noted)

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for any given financial instrument is based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument.

In certain cases, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices, market transactions in comparable investments and various relationships between investments.

In the absence of observable market prices, Blackstone values its investments using valuation methodologies applied on a consistent basis. For some investments little market activity may exist; management’s determination of fair value is then based on the best information available in the circumstances, and may incorporate management’s own assumptions and involves a significant degree of judgment, taking into consideration a combination of internal and external factors, including the appropriate risk adjustments for non-performance and liquidity risks. Investments for which market prices are not observable include private investments in the equity of operating companies, real estate properties or certain funds of hedge funds. The valuation technique for each of these investments is described below:

Private Equity Investments — The fair values of private equity investments are determined by reference to projected net earnings, earnings before interest, taxes, depreciation and amortization (“EBITDA”), the discounted cash flow method, public market or private transactions, valuations for comparable companies and other measures which, in many cases, are unaudited at the time received. Valuations may be derived by reference to observable valuation measures for comparable companies or transactions (e.g., multiplying a key performance metric of the investee company such as EBITDA by a relevant valuation multiple observed in the range of comparable companies or transactions), adjusted by management for differences between the investment and the referenced comparables, and in some instances by reference to option pricing models or other similar methods. Private equity investments may also be valued at cost for a period of time after an acquisition as the best indicator of fair value.

Real Estate Investments — The fair values of real estate investments are determined by considering projected operating cash flows, sales of comparable assets, if any, and replacement costs among other measures. The methods used to estimate the fair value of real estate investments include the discounted cash flow method and/or capitalization rates (“cap rates”) analysis. Valuations may be derived by reference to observable valuation measures for comparable companies or assets (e.g., multiplying a key performance metric of the investee company or asset, such as EBITDA, by a relevant valuation multiple observed in the range of comparable companies or transactions), adjusted by management for differences between the investment and the referenced comparables, and in some instances by reference to option pricing models or other similar methods. Additionally, where applicable, projected distributable cash flow through debt maturity will also be considered in support of the investment’s carrying value.

Funds of Hedge Funds — Blackstone Funds’ direct investments in funds of hedge funds (“Investee Funds”) are valued at net asset value (“NAV”) per share of the Investee Fund. If the Partnership determines, based on its own due diligence and investment procedures, that NAV per share does not represent fair value, the Partnership will estimate the fair value in good faith and in a manner that it reasonably chooses, in accordance with its valuation policies.

Notes to Condensed Consolidated Financial Statements—(Continued)

(All Dollars Are in Thousands, Except Unit and Per Unit Data, Except Where Noted)

Credit-Oriented Investments — The fair values of credit-oriented investments are generally determined on the basis of prices between market participants provided by reputable dealers or pricing services. In some instances, Blackstone may utilize other valuation techniques, including the discounted cash flow method.

Investments, at Fair Value

The Blackstone Funds are accounted for as investment companies under the AICPA Audit and Accounting Guide, Investment Companies , and reflect their investments, including majority-owned and controlled investments (the “Portfolio Companies”), at fair value. Blackstone has retained the specialized accounting for the consolidated Blackstone Funds. Thus, such consolidated funds’ investments are reflected in Investments on the Condensed Consolidated Statements of Financial Condition at fair value, with unrealized gains and losses resulting from changes in fair value reflected as a component of Net Gains (Losses) from Fund Investment Activities in the Condensed Consolidated Statements of Operations. Fair value is the amount 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 (i.e., the exit price).

Blackstone’s principal investments are presented at fair value with unrealized appreciation or depreciation and realized gains and losses recognized in the Condensed Consolidated Statements of Operations within Investment Income (Loss).

For certain instruments, the Partnership has elected the fair value option. Such election is irrevocable and is applied on an investment by investment basis at initial recognition. The Partnership has applied the fair value option for certain loans and receivables and certain investments in private debt and equity securities, that otherwise would not have been carried at fair value with gains and losses recorded in net income, to consistently account for principal investments held by the Partnership. Loans extended to third parties are recorded within Accounts Receivable within the Condensed Consolidated Statements of Financial Condition. Debt and equity securities for which the fair value option has been elected are recorded within Investments. The methodology for measuring the fair value of such investments is consistent with the methodology applied to private equity, real estate, credit-oriented and funds of hedge funds investments. Changes in the fair value of such instruments are recognized in Investment Income (Loss) in the Condensed Consolidated Statements of Operations. Interest income on interest bearing loans and receivables and debt securities on which the fair value option has been elected is based on stated coupon rates adjusted for the accretion of purchase discounts and the amortization of purchase premiums. This interest income is recorded within Interest and Dividend Revenue.

In addition, the Partnership has elected the fair value option for the assets and liabilities of certain collateralized loan obligations (“CLO”) vehicles that are consolidated as of January 1, 2010, as a result of the initial adoption of revised variable interest entity consolidation rules. The Partnership has also elected the fair value option for CLO vehicles consolidated as of April 1, 2010 as a result of the acquisitions of CLO management contracts as described in Note 3. “Acquisitions, Goodwill and Intangibles.” The transition adjustment resulting from the difference between the fair value of assets and liabilities for each of these events is presented within the Condensed Consolidated Statement of Changes in Partners’ Capital as Appropriated Partners’ Capital. Assets of the consolidated CLOs are presented within Investments within the Condensed Consolidated Statements of Financial Condition and Liabilities within Loans Payable for the amounts due to unaffiliated third parties and Due to Affiliates for the amounts held by non-consolidated affiliates. Changes in the fair value of consolidated CLO assets and liabilities and related interest, dividend and other income subsequent to adoption are presented within Net Gains (Losses) from Fund Investment Activities and are attributable to Non-Controlling Interests in Consolidated Entities in the Condensed Consolidated Statements of Operations.

Further disclosure on instruments for which the fair value option has been elected is presented in Note 7. “Fair Value Option” to the Condensed Consolidated Financial Statements.

Security and loan transactions are recorded on a trade date basis.

Equity Method Investments

Investments where the Partnership is deemed to exert significant influence, but not control, are accounted for using the equity method of accounting. Under the equity method of accounting, the Partnership’s share of earnings (losses) from equity method investments is included in Investment Income (Loss) in the Condensed Consolidated Statements of Operations. The carrying amounts of equity method investments are reflected in Investments in the Condensed Consolidated Statements of Financial Condition. As the underlying investments of the Partnership’s equity method investments are reported at fair value, the carrying value of the Partnership’s equity method investments are at fair value.

Derivative Instruments

The Partnership recognizes all derivatives as assets or liabilities on its Condensed Consolidated Statements of Financial Condition at fair value. On the date the Partnership enters into a derivative contract, it designates and documents each derivative contract as one of the following: (a) a hedge of a recognized asset or liability (“fair value hedge”), (b) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”); (c) a hedge of a net investment in a foreign operation; or (d) a derivative instrument not designated as a hedging instrument (“free standing derivative”). For a fair value hedge, Blackstone records changes in the fair value of the derivative and, to the extent that it is highly effective, changes in the fair value of the hedged asset or liability attributable to the hedged risk, in current period earnings in the same caption in the Condensed Consolidated Statements of Operations as the hedged item. Changes in the fair value of derivatives designated as hedging instruments caused by factors other than changes in the risk being hedged, which are excluded from the assessment of hedge effectiveness, are recognized in current period earnings. For free standing derivative contracts, the Partnership presents changes in fair value in current period earnings.

The Partnership formally documents at inception its hedge relationships, including identification of the hedging instruments and the hedged items, its risk management objectives, strategy for undertaking the hedge transaction and the Partnership’s evaluation of effectiveness of its hedged transaction. On a monthly basis, the Partnership also formally assesses whether the derivative it designated in each hedging relationship is expected to be, and has been, highly effective in offsetting changes in estimated fair values or cash flows of the hedged items using either the regression analysis or the dollar offset method. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued.

Blackstone’s other disclosures regarding derivative financial instruments are discussed in Note 6. “Derivative Financial Instruments”.

Cash Distribution Policy

Blackstone’s current intention is to distribute to its common unitholders substantially all of The Blackstone Group L.P.’s net after-tax share of annual Distributable Earnings in excess of amounts determined by Blackstone’s general partner to be necessary or appropriate to provide for the conduct of the Partnership’s business, to make appropriate investments in the business and funds, to comply with applicable law, any of Blackstone’s debt instruments or other agreements, or to provide for future distributions to Blackstone’s common unitholders for any ensuing quarter. Because Blackstone will not know what Distributable Earnings will be for

14

Table of Contents

THE BLACKSTONE GROUP L.P.

Notes to Condensed Consolidated Financial Statements—(Continued)

(All Dollars Are in Thousands, Except Unit and Per Unit Data, Except Where Noted)

any fiscal year until the end of such year, the Partnership expects that the first three quarterly distributions in respect of any given year will be based on the anticipated annualized Net Fee Related Earnings only. As such, the distribution for the first three quarters will likely be smaller than the final quarterly distribution in respect of such year. Blackstone expects to also reflect realized Performance Fees and Allocations net of related compensation and realized net investment income in its determination of the amount of the fourth quarter distribution.

In most years the aggregate amounts of distributions to unitholders will not equal Distributable Earnings for that year. Distributable Earnings will only be a starting point for the determination of the amount to be distributed to unitholders because as noted above, in determining the amount to be distributed Blackstone will subtract from Distributable Earnings any amounts determined by its general partner to be necessary or appropriate to provide for the conduct of its business, to make appropriate investments in its business and its funds, to comply with applicable law, any of its debt instruments or other agreements, or to provide for future distributions to its unitholders for any ensuing quarter.

All of the foregoing is subject to the qualification that the declaration and payment of any distributions are at the sole discretion of the general partner and the general partner may change the distribution policy at any time.

Because The Blackstone Group L.P. is a holding partnership and has no material assets other than its ownership of partnership units in Blackstone Holdings held through wholly-owned subsidiaries, distributions by The Blackstone Group L.P., if any, are funded in three steps:

As a result of the expiration on December 31, 2009 of the distribution priority previously accorded to holders of Blackstone common units, the Partnership no longer has two classes of equity. The calculation of net loss per common unit is presented using one class of equity for the period ended June 30, 2010, as shown in Note 12. “Net Loss Per Common Unit.”

Because the wholly-owned subsidiaries of The Blackstone Group L.P. must pay taxes and make payments under the tax receivable agreements described in Note 14. “Related Party Transactions”, the amounts ultimately distributed by The Blackstone Group L.P. to common unitholders in respect of fiscal 2010 and subsequent years are expected to be different, and likely less, on a per unit basis, than the amounts distributed by the Blackstone Holdings partnerships to the Blackstone personnel and others who are limited partners of the Blackstone Holdings partnerships in respect of their Blackstone Holdings partnership units.

In addition, the partnership agreements of the Blackstone Holdings partnerships provide for cash distributions, which are referred to as “tax distributions,” to the partners of such partnerships if the wholly-owned subsidiaries of The Blackstone Group L.P. which are the general partners of the Blackstone Holdings partnerships determine that the taxable income of the relevant partnership will give rise to taxable income for the partners. Generally, these tax distributions will be computed based on the Partnership’s estimate of the net

15

THE BLACKSTONE GROUP L.P.

Notes to Condensed Consolidated Financial Statements—(Continued)

(All Dollars Are in Thousands, Except Unit and Per Unit Data, Except Where Noted)

taxable income of the relevant partnership allocable to a partner multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate prescribed for an individual or corporate resident in New York, New York (taking into account the nondeductibility of certain expenses and the character of the Partnership’s income). The Blackstone Holdings partnerships will make tax distributions only to the extent distributions from such partnerships for the relevant year were otherwise insufficient to cover such estimated assumed tax liabilities.

Recent Accounting Developments

On January 1, 2010, the Partnership adopted guidance issued by the Financial Accounting Standards Board (“FASB”) on issues related to variable interest entities (“VIEs”). The amendments significantly affect the overall consolidation analysis, changing the approach taken by companies in identifying which entities are VIEs and in determining which party is the primary beneficiary. The guidance requires continuous assessment of the reporting entity’s involvement with such VIEs. The revised guidance also enhances the disclosure requirements for a reporting entity’s involvement with VIEs, including presentation on the Condensed Consolidated Statements of Financial Condition of assets and liabilities of consolidated VIEs which meet the separate presentation criteria and disclosure of assets and liabilities recognized in the Condensed Consolidated Statements of Financial Condition and the maximum exposure to loss for those VIEs in which a reporting entity is determined to not be the primary beneficiary but in which it has a variable interest. The guidance provides a limited scope deferral for a reporting entity’s interest in an entity that meets all of the following conditions: (a) the entity has all the attributes of an investment company as defined under AICPA Audit and Accounting Guide, Investment Companies , or does not have all the attributes of an investment company but is an entity for which it is acceptable based on industry practice to apply measurement principles that are consistent with the AICPA Audit and Accounting Guide, Investment Companies , (b) the reporting entity does not have explicit or implicit obligations to fund any losses of the entity that could potentially be significant to the entity, and (c) the entity is not a securitization entity, asset-backed financing entity or an entity that was formerly considered a qualifying special-purpose entity. The reporting entity is required to perform a consolidation analysis for entities that qualify for the deferral in accordance with previously issued guidance on variable interest entities. Blackstone’s involvement with its funds is such that all three of the above conditions are met with the exception of certain CLO vehicles which fail condition (c) above and certain funds in which leveraged employee interests in dedicated funds are financed by third parties with Blackstone acting as an intermediary which fail condition (b) above. Such employee funds are currently consolidated as it is concluded that Blackstone is the primary beneficiary based on its implicit interest. The incremental impact of the revised consolidation rules has resulted in the consolidation of certain CLO vehicles managed by Blackstone. Additional disclosures relating to Blackstone’s involvement with VIEs are presented in Note 9. “Variable Interest Entities” of the Partnership’s financial statements.

In January 2010, the FASB issued guidance on improving disclosures about fair value measurements. The guidance requires additional disclosure on transfers in and out of Levels I and II fair value measurements in the fair value hierarchy and the reasons for such transfers. In addition, for fair value measurements using significant unobservable inputs (Level III), the reconciliation of beginning and ending balances shall be presented on a gross basis, with separate disclosure of gross purchases, sales, issuances and settlements and transfers in and transfers out of Level III. The new guidance also requires enhanced disclosures on the fair value hierarchy to disaggregate disclosures by each class of assets and liabilities. In addition, an entity is required to provide further disclosures on valuation techniques and inputs used to measure fair value for fair value measurements that fall in either Level II or Level III. The guidance is effective for interim and annual periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level III fair value measurements, which are effective for fiscal years beginning after December 15, 2010. The

Partnership adopted the guidance, excluding the reconciliation of Level III activity, with the issuance of its March 31, 2010 financial statements. As the guidance is limited to enhanced disclosures, adoption did not have a material impact on the Partnership’s financial statements.

In April 2010, the FASB issued guidance on the accounting for stock awards to employees of a foreign operation or employees whose pay is denominated in a currency other than the one in which the equity security trades. The guidance clarifies that share-based payment awards with an exercise price denominated in the currency of a market in which a substantial portion of the entity’s equity securities trade shall not be considered to contain a condition that is not a market, performance, or service condition. Such an award shall not be classified as a liability if it otherwise qualifies for equity classification. The guidance is effective for fiscal years and interim periods ending after December 15, 2010. Blackstone makes share-based payment awards to employees in foreign operations. The guidance is not expected to have a material impact on the Partnership’s financial statements.

Acquisition
