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, collateralized loan obligation (“CLO”) vehicles, separately managed accounts, publicly traded closed-end mutual funds and registered investment companies (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 five segments: private equity, real estate, hedge fund solutions, credit businesses, 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.

Generally, 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 audited 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 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 for the year ended December 31, 2010 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 general partner is presumed to have control.

All intercompany balances and transactions have been eliminated in consolidation.

Restructurings within consolidated CLOs are treated as investment purchases or sales, as applicable, in the Condensed Consolidated Statements of Cash Flows.

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 economic performance 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 consolidation guidance requires 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. Variable interest entities qualify for the deferral of this consolidation guidance if all of the following conditions have been met:

Where the VIEs have qualified for the deferral of the current consolidation guidance, the analysis is based on previous consolidation guidance. This guidance requires an analysis to determine (a) 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 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 and its affiliates 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.

Assets of consolidated VIEs that can only be used to settle obligations of the consolidated VIE and liabilities of a consolidated VIE for which creditors (or beneficial interest holders) do not have recourse to the

general credit of Blackstone are presented in a separate section in the Condensed Consolidated Statements of Financial Condition.

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:

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

12

Notes to Condensed Consolidated Financial Statements—(Continued)

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

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.

Transfers between levels of the fair value hierarchy are recognized at the beginning of the reporting period.

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.

(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 Investment Company Guide, 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 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. Fair valuing these investments is consistent with how the Partnership accounts for its other principal investments. 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 CLO vehicles that are consolidated as of January 1, 2010, as a result of the initial adoption of variable interest entity consolidation guidance. The Partnership has also elected the fair value option for CLO vehicles consolidated as a result of the acquisitions of CLO management contracts. The adjustment resulting from the difference between the fair value of assets and liabilities for each of these events is presented as a transition and acquisition adjustment to Appropriated Partners’ Capital. Assets of the consolidated CLOs are presented within Investments within the 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. The methodology for measuring the fair value of such assets and liabilities is consistent with the methodology applied to private equity, real estate, and credit-oriented investments. Changes in the fair value of consolidated CLO assets and liabilities and related interest, dividend and other income subsequent to adoption and acquisition are presented within Net Gains from Fund Investment Activities. Amounts attributable to Non-Controlling Interests in Consolidated Entities have a corresponding adjustment to Appropriated Partners’ Capital.

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 in Blackstone Funds are reported at fair value, the carrying value of the Partnership’s equity method investments represents fair value. Other equity method investments are reviewed for impairment.

Repurchase and Reverse Repurchase Agreements

Securities purchased under agreement to resell (“reverse repurchase agreements”) and securities sold under agreements to repurchase (“repurchase agreements”), comprising primarily U.S. and non-U.S. government and agency securities, asset-backed securities and corporate debt, represent collateralized financing transactions. Such transactions are recorded in the Condensed Consolidated Statements of Financial Condition at their contractual amounts and include accrued interest.

The Partnership manages credit exposure arising from repurchase agreements and reverse repurchase agreements by, in appropriate circumstances, entering into master netting agreements and collateral arrangements with counterparties that provide the Partnership, in the event of a customer default, the right to liquidate collateral and the right to offset a counterparty’s rights and obligations.

The Partnership takes possession of securities purchased under reverse repurchase agreements and is permitted to repledge, deliver or otherwise use such securities. The Partnership also pledges its financial instruments to counterparties to collateralize repurchase agreements. Financial instruments pledged that can be repledged, delivered or otherwise used by the counterparty are recorded in Investments on the Condensed Consolidated Statements of Financial Condition.

Securities Sold, Not Yet Purchased

Securities Sold, Not Yet Purchased consist of equity and debt securities that the Partnership has borrowed and sold. The Partnership is required to “cover” its short sale in the future by purchasing the security at prevailing market prices and delivering it to the counterparty from which it borrowed the security. The Partnership is exposed to loss in the event that the price at which a security may have to be purchased to cover a short sale exceeds the price at which the borrowed security was sold short.

Securities Sold, Not Yet Purchased are recorded at fair value in the Condensed Consolidated Statements of Financial Condition.

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 (“freestanding 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 freestanding 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. At least monthly, 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”.

Affiliates

Blackstone considers its Founder, senior managing directors, employees, the Blackstone Funds and the Portfolio Companies to be affiliates.

Distributions

Distributions are reflected in the condensed consolidated financial statements when paid.

Recent Accounting Developments

In January 2010, the FASB issued guidance on improving disclosures about fair value measurements. The guidance required 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 guidance required the reconciliation of beginning and ending balances 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 guidance also required enhanced disclosures on the fair value hierarchy to disaggregate disclosures by each class of assets and liabilities. In addition, the guidance required an entity 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 was effective for interim and annual periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements

16

Notes to Condensed Consolidated Financial Statements—(Continued)

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

in the roll forward of activity in Level III fair value measurements, which was effective for fiscal years beginning after December 15, 2010. Adoption of the guidance, including the gross presentation of activity in Level III, did not have a material impact on the Partnership’s financial statements.

In December 2010, the FASB issued enhanced guidance on when to perform step two of the goodwill impairment test for reporting units with zero or negative carrying amounts. The updated guidance modified existing requirements under step one of the goodwill impairment test for reporting units with zero or negative carrying amounts and required step two to be performed if it is more likely than not that a goodwill impairment exists. The guidance was effective for interim and annual reporting periods beginning after December 15, 2010. Adoption did not have a material impact on the Partnership’s financial statements.

In December 2010, the FASB issued guidance on disclosures around business combinations for public entities that present comparative financial statements. The guidance specified that an entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period. The guidance was effective prospectively for business combinations for which the acquisition date was on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. As the Partnership has not had any business combinations since January 2011, adoption did not have a material impact on the Partnership’s financial statements.

In April 2011, the FASB amended existing guidance for agreements to transfer financial assets that both entitle and obligate the transferor to repurchase or redeem the financial assets before their maturity. The amendments remove from the assessment of effective control (a) the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee and (b) the collateral maintenance implementation guidance related to that criterion. The guidance is effective for the first interim or annual period beginning on or after December 15, 2011. Blackstone enters into repurchase agreements that are currently accounted for as collateralized financing transactions. Adoption is not expected to have a material impact on the Partnership’s financial statements.

In May 2011, the FASB issued amended guidance on fair value measurements to achieve common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards. The amended guidance specifies that the concepts of highest and best use and valuation premise in a fair value measurement are relevant only when measuring the fair value of nonfinancial assets and are not relevant when measuring the fair value of financial assets or of liabilities. The amendments include requirements specific to measuring the fair value of those instruments, such as equity interests used as consideration in a business combination. An entity should measure the fair value of its own equity instrument from the perspective of a market participant that holds the instrument as an asset. With respect to financial instruments that are managed as part of a portfolio, an exception to fair value requirements is provided. That exception permits a reporting entity to measure the fair value of such financial assets and financial liabilities at the price that would be received to sell a net asset position for a particular risk or to transfer a net liability position for a particular risk in an orderly transaction between market participants at the measurement date. The amendments also clarify that premiums and discounts should only be applied if market participants would do so when pricing the asset or liability. Premiums and discounts related to the size of an entity’s holding (e.g., a blockage factor) rather than as a characteristic of the asset or liability (e.g., a control premium) is not permitted in a fair value measurement.

The guidance also requires enhanced disclosures about fair value measurements, including, among other things, (a) for fair value measurements categorized within Level III of the fair value hierarchy, (1) a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, (2) the valuation process used

17

THE BLACKSTONE GROUP L.P.

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

by the reporting entity, and (3) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any, and (b) the categorization by level of the fair value hierarchy for items that are not measured at fair value in the statement of financial position but for which the fair value is required to be disclosed (for example, a financial instrument that is measured at amortized cost in the statement of financial position but for which fair value is disclosed). The guidance also amends disclosure requirements for significant transfers between Level I and Level II and now requires disclosure of all transfers between Levels I and II in the fair value hierarchy.

The amended guidance is effective for interim and annual periods beginning after December 15, 2011. As the impact of the guidance is primarily limited to enhanced disclosures, adoption is not expected to have a material impact on the Partnership’s financial statements.

In June 2011, the FASB issued amended guidance on the presentation of comprehensive income. The amendments provide an entity with an option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. The guidance is effective for fiscal years, and interim periods within those years beginning after December 15, 2011 and should be applied on a retrospective basis. As the amendments are limited to presentation only, adoption is not expected to have a material impact on the Partnership’s financial statements.

In September 2011, the FASB issued enhanced guidance on testing goodwill for impairment. The amended guidance provides an entity with the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if any. Under the amended guidance, an entity has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The amended guidance includes examples of events or circumstances that an entity must consider in evaluating whether it is more likely than not that the fair value of reporting units is less than its carrying amount. The amended guidance no longer permits the carry forward of detailed calculations of a reporting unit’s fair value from a prior year. The guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. Blackstone is evaluating the impact of the amended guidance on its annual and interim goodwill impairment tests. The amended guidance is not expected to have a material impact on the Partnership’s financial statements.

Acquisition

On May 16, 2011, the Partnership, through GSO, completed the acquisition of management agreements relating to four collateralized loan obligation vehicles previously managed by Allied Irish Bank for net consideration of $23.4 million. The assets acquired are finite-lived contractual rights.

Goodwill and Intangible Assets

In January 2011, Blackstone separated its Credit and Marketable Alternatives segment into two new segments. Goodwill previously allocated to the Credit and Marketable Alternatives segment has been reallocated to the Hedge Fund Solutions and Credit Businesses segments. Goodwill has been allocated to each of the Partnership’s five segments as follows: Private Equity ($694.5 million), Real Estate ($421.7 million), Hedge Fund Solutions ($172.1 million), Credit Businesses ($346.4 million) and Financial Advisory ($68.9 million).

The carrying value of goodwill was $1.7 billion as of September 30, 2011 and December 31, 2010. As of September 30, 2011 and December 31, 2010, the fair value of the Partnership’s operating segments substantially exceeded their respective carrying values.

Intangible Assets, Net consists of the following:

Amortization expense associated with Blackstone’s intangible assets was $42.4 million and $124.8 million for the three and nine month periods ended September 30, 2011, respectively, and $40.9 million and $121.2 million for the three and nine month periods ended September 30, 2010, respectively.

Amortization of Intangible Assets held at September 30, 2011 is expected to be $167.1 million, $114.6 million, $63.1 million, $58.2 million, and $52.0 million for each of the years ending December 31, 2011, 2012, 2013, 2014, and 2015, respectively. Blackstone’s intangible assets as of September 30, 2011 are expected to amortize over a weighted-average period of 9.6 years.

Blackstone’s share of Investments of Consolidated Blackstone Funds totaled $449.5 million and $500.2 million at September 30, 2011 and December 31, 2010, respectively.

At September 30, 2011 and December 31, 2010, consideration was given as to whether any individual investment, including derivative instruments, had a fair value which exceeded 5% of Blackstone’s net assets. At September 30, 2011 and December 31, 2010, no investment exceeded the 5% threshold.

Investments of Consolidated Blackstone Funds

Net Gains (Losses) from Fund Investment Activities on the Condensed Consolidated Statements of Operations includes net realized gains (losses) from realizations and sales of investments and the net change in unrealized gains (losses) resulting from changes in the fair value of the consolidated Blackstone Funds’ investments. The following table presents the realized and net change in unrealized gains (losses) on investments held by the consolidated Blackstone Funds:

Certain of the consolidated Blackstone funds of hedge funds and credit-oriented funds measure their investments in underlying funds at fair value using NAV per share without adjustment. The terms of the investee’s investment generally provide for minimum holding periods or lock-ups, the institution of gates on redemptions or the suspension of redemptions or an ability to side-pocket investments, at the discretion of the investee’s fund manager, and as a result, investments may not be redeemable at, or within three months of, the reporting date. A side-pocket is used by hedge funds and funds of hedge funds to separate investments that may lack a readily ascertainable value, are illiquid or are subject to liquidity restriction. Redemptions are generally not permitted until the investments within a side pocket are liquidated or it is deemed that the conditions existing at the time that required the investment to be included in the side-pocket no longer exist. As the timing of either of these events is uncertain, the timing at which the Partnership may redeem an investment held in a side-pocket cannot be estimated. A summary of fair value by strategy type alongside the consolidated funds of hedge funds’ remaining unfunded commitments and ability to redeem such investments as of September 30, 2011 is presented below:
