Basis of Presentation

The accompanying consolidated financial statements of the Partnership have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Subsequent to the Reorganization, the 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 Consolidated Statements of Cash Flows.

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

Use of Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Management believes that estimates utilized in the preparation of the consolidated financial statements are prudent and reasonable and that it has made all necessary adjustments (consisting of only normal recurring items) so that the consolidated financial statements are presented fairly. Actual results could differ from those estimates and such differences could be material.

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 VIE 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 VIE. The consolidation guidance requires an analysis to (a) determine whether an entity in which the Partnership holds a variable interest is a VIE 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. VIEs qualify for the deferral of the 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 variable interest entities 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 Consolidated Statements of Financial Condition.

Blackstone's other disclosures regarding VIEs are discussed in Note 9. "Variable Interest Entities".

Business Combinations

For business combinations transacted prior to January 1, 2009, the Partnership has accounted for acquisitions using the purchase method of accounting, under which the purchase price of the acquisition is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date.

For business combinations transacted after January 1, 2009, the Partnership accounted for such combinations by recognizing the full fair value of assets, liabilities, contingencies and contingent consideration obtained in the transaction at the acquisition date. Transaction costs have been expensed as incurred.

Revenue Recognition

Revenues primarily consist of management and advisory fees, performance fees, investment income, interest and dividend revenue and other.

Management and Advisory Fees—Management and Advisory Fees are comprised of management fees, including base management fees, transaction and other fees, management fee reductions and offsets, and advisory fees.

The Partnership earns base management fees from limited partners of funds in each of its managed funds, at a fixed percentage of assets under management, net asset value, total assets, committed capital, invested capital or, in some cases, a fixed fee. Base management fees are based on contractual terms specified in the underlying investment advisory agreements.

Transaction and other fees (including monitoring fees) are fees charged directly to funds and portfolio companies. The investment advisory agreements generally require that the investment adviser reduce the amount of management fees payable by the limited partners to the Partnership ("management fee reductions") by an amount equal to a portion of the transaction and other fees directly paid to the Partnership by the portfolio companies. The amount of the reduction varies by fund, the type of fee paid by the portfolio company and the previously incurred expenses of the fund.

Management fee offsets are reductions to management fees payable by limited partners, which are granted based on the amount they reimburse Blackstone for placement fees.

Advisory fees consist of advisory retainer and transaction-based fee arrangements related to merger, acquisition, restructuring and divestiture activities and fund placement services for alternative investment funds. Advisory retainer fees are recognized when services for the transactions are complete, in accordance with terms set forth in individual agreements. Transaction-based fees are recognized when (a) there is evidence of an arrangement with a client, (b) agreed upon services have been provided, (c) fees are fixed or determinable and (d) collection is reasonably assured. Fund placement fees are recognized as earned upon the acceptance by a fund of capital or capital commitments.

Accrued but unpaid Management and Advisory Fees, net of management fee reductions and management fee offsets, as of the reporting date, are included in Accounts Receivable or Due From Affiliates in the Consolidated Statements of Financial Condition.

Performance Fees—Performance fees earned on the performance of Blackstone's hedge fund structures are recognized based on fund performance during the period, subject to the achievement of minimum return levels, or high water marks, in accordance with the respective terms set out in each hedge fund's governing agreements. Accrued but unpaid performance fees charged directly to investors in Blackstone's offshore hedge funds as of the reporting date are recorded within Due from Affiliates in the Consolidated Statements of Financial Condition. Performance fees arising on Blackstone's onshore hedge funds are allocated to the general partner. Accrued but unpaid performance fees on onshore funds as of the reporting date are reflected in Investments in the Consolidated Statements of Financial Condition.

In certain fund structures, specifically in private equity, real estate and certain credit-oriented funds ("Carry Funds"), performance fees ("Carried Interest") are allocated to the general partner based on cumulative fund performance to date, subject to a preferred return to limited partners. At the end of each reporting period, the Partnership calculates the Carried Interest that would be due to the Partnership for each fund, pursuant to the fund agreements, as if the fair value of the underlying investments were realized as of such date, irrespective of whether such amounts have been realized. As the fair value of underlying investments varies between reporting periods, it is necessary to make adjustments to amounts recorded as Carried Interest to reflect either (a) positive performance resulting in an increase in the Carried Interest allocated to the general partner or (b) negative performance that would cause the amount due to the Partnership to be less than the amount previously recognized as revenue, resulting in a negative adjustment to Carried Interest allocated to the general partner. In each scenario, it is necessary to calculate the Carried Interest on cumulative results compared to the Carried Interest recorded to date and make the required positive or negative adjustments. The Partnership ceases to record negative Carried Interest allocations once previously recognized Carried Interest allocations for such fund have been fully reversed. The Partnership is not obligated to pay guaranteed returns or hurdles, and therefore, cannot have negative Carried Interest over the life of a fund. Accrued but unpaid Carried Interest as of the reporting date is reflected in Investments in the Consolidated Statements of Financial Condition.

Carried Interest is realized when an underlying investment is profitably disposed of and the fund's cumulative returns are in excess of the preferred return. Performance fees earned on hedge fund structures are realized at the end of each fund's measurement period.

Carried Interest is subject to clawback to the extent that the Carried Interest actually distributed to date exceeds the amount due to Blackstone based on cumulative results. As such, the accrual for potential repayment of previously received performance fees, which is a component of Due to Affiliates, represents all amounts previously distributed to Blackstone Holdings and non-controlling interest holders that would need to be repaid to the Blackstone Funds if the Blackstone Carry Funds were to be liquidated based on the current fair value of the underlying funds' investments as of the reporting date. Generally, the actual clawback liability does not become realized until the end of a fund's life or one year after a realized loss is incurred, depending on the fund.

Investment Income (Loss)—Investment Income (Loss) represents the unrealized and realized gains and losses on the Partnership's principal investments, including its investments in Blackstone Funds that are not consolidated, its equity method investments, and other principal investments. Investment Income (Loss) is realized when the Partnership redeems all or a portion of its investment or when the Partnership receives cash income, such as dividends or distributions, from its non-consolidated funds. Unrealized Investment Income (Loss) results from changes in the fair value of the underlying investment as well as the reversal of unrealized gain (loss) at the time an investment is realized.

Interest and Dividend Revenue—Interest and Dividend Revenue comprises primarily interest and dividend income earned on principal investments held by Blackstone.

Other Revenue—Other Revenue consists of foreign exchange gains and losses arising on transactions denominated in currencies other than U.S. dollars and other revenues.

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 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.

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. Investments for which fair value is measured using NAV per share are reflected within the fair value hierarchy based on the observability of pricing inputs as described above. Further disclosure on instruments for which fair value is measured using NAV per share is presented in Note 5. "Net Asset Value as Fair Value".

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 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 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 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 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 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 as described in Note 3. "Acquisitions, Goodwill and Intangible Assets." 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".

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 Consolidated Statements of Operations. The carrying amounts of equity method investments are reflected in Investments in the 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.

Cash and Cash Equivalents

Cash and cash equivalents represents cash on hand, cash held in banks and liquid investments with original maturities of three months or less. Interest income from cash and cash equivalents is recorded in Interest and Dividend Revenue in the Consolidated Statements of Operations.

Cash Held By Blackstone Funds and Other

Cash held by Blackstone Funds and Other represents cash and cash equivalents held by consolidated Blackstone Funds and other consolidated entities. Such amounts are not available to fund the general liquidity needs of Blackstone.

Accounts Receivable

Accounts Receivable includes management fees receivable from limited partners, receivables from underlying funds in the fund of hedge funds business, placement and advisory fees receivables, and loans extended to unaffiliated third parties. Accounts Receivable, excluding those for which the fair value option has been elected, are assessed periodically for collectibility. Amounts determined to be uncollectible are charged directly to General, Administrative and Other Expenses in the Consolidated Statements of Operations.

Intangibles and Goodwill

Blackstone's intangible assets consist of contractual rights to earn future fee income, including management and advisory fees and Carried Interest from its Carry Funds. Identifiable finite-lived intangible assets are amortized on a straight line basis over their estimated useful lives, ranging from 4 to 20 years, reflecting the contractual lives of such funds. Amortization expense is included within General, Administrative and Other in the accompanying Consolidated Statements of Operations. The Partnership does not hold any indefinite-lived intangible assets.

Goodwill comprises goodwill arising from the contribution and reorganization of the Partnership's predecessor entities in 2007 immediately prior to its IPO and the acquisition of GSO in 2008.

Intangible assets and goodwill are reviewed for impairment at least annually, and more frequently if circumstances indicate impairment may have occurred.

Furniture, Equipment and Leasehold Improvements

Furniture, equipment and leasehold improvements consist primarily of leasehold improvements, furniture, fixtures and equipment, computer hardware and software and are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight line method over the assets' estimated useful economic lives, which for leasehold improvements are the lesser of the lease terms or the life of the asset, generally fifteen years, and three to seven years for other fixed assets. The Partnership evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Foreign Currency  

In the normal course of business, the Partnership may enter into transactions not denominated in United States dollars. Foreign exchange gains and losses arising on such transactions are recorded as Other Revenue in the Consolidated Statements of Operations. Foreign currency transaction gains and losses arising within consolidated Blackstone Funds are recorded in Net Gains (Losses) from Fund Investment Activities. In addition, the Partnership consolidates a number of entities that have a non-U.S. dollar functional currency. Non-U.S. dollar denominated assets and liabilities are translated to U.S. dollars at the exchange rate prevailing at the reporting date and income, expenses, gains and losses are translated at the prevailing exchange rate on the dates that they were recorded. Cumulative translation adjustments arising from the translation of non-U.S. dollar denominated operations are recorded in Other Comprehensive Income.  

Comprehensive Income

Comprehensive Income consists of Net Income and Other Comprehensive Income. The Partnership's Other Comprehensive Income is comprised of foreign currency cumulative translation adjustments.

Non-Controlling Interests in Consolidated Entities

Non-Controlling Interests in Consolidated Entities represent the component of Partners' Capital in consolidated entities held by third party investors. Such interests are adjusted for general partner allocations and by subscriptions and redemptions in funds of hedge funds and certain credit-oriented funds which occur during the reporting period. Non-controlling interests related to funds of hedge funds and certain other credit-oriented funds are subject to annual, semi-annual or quarterly redemption by investors in these funds following the expiration of a specified period of time (typically between one and three years), or may be withdrawn subject to a redemption fee in the funds of hedge funds and certain credit-oriented funds during the period when capital may not be withdrawn. As limited partners in these types of funds have been granted redemption rights, amounts relating to third party interests in such consolidated funds are presented as Redeemable Non-Controlling Interests in Consolidated Entities within the Consolidated Statements of Financial Condition. When redeemable amounts become legally payable to investors, they are classified as a liability and included in Accounts Payable, Accrued Expenses and Other in the Consolidated Statements of Financial Condition. For all consolidated funds in which redemption rights have not been granted, non-controlling interests are presented within Partners' Capital in the Consolidated Statements of Financial Condition as Non-Controlling Interests in Consolidated Entities.

Compensation and Benefits

Compensation and Benefits—Compensation—Compensation and benefits consists of (a) employee compensation, comprising salary and bonus, and benefits paid and payable to employees, including senior managing directors, and (b) equity-based compensation associated with the grants of equity-based awards to employees, including senior managing directors.

Equity-Based Compensation—Compensation cost relating to the issuance of share-based awards to senior managing directors and employees is measured at fair value at the grant date, taking into consideration expected forfeitures, and expensed over the vesting period on a straight line basis. Equity-based awards that do not require future service are expensed immediately. Cash settled equity-based awards are classified as liabilities and are re-measured at the end of each reporting period.

Compensation and Benefits—Performance Fee—Performance fee compensation and benefits consists of Carried Interest and performance fee allocations to employees, including senior managing directors, participating in certain profit sharing initiatives. Such compensation expense is subject to both positive and negative adjustments. Unlike Carried Interest and performance fees, compensation expense is based on the performance of individual investments held by a fund rather than on a fund by fund basis.

Other Income

Other Income includes the amount attributable to the Reversal of the Tax Receivable Liability. This is non-recurring income attributable to a change in tax rate as discussed in Note 13. "Income Taxes".

Net Gains (Losses) from Fund Investment Activities on the Consolidated Statements of Operations include net realized gains (losses) from realizations and sales of investments, the net change in unrealized gains (losses) resulting from changes in the fair value and interest income and expense and dividend attributable to the consolidated Blackstone Funds' investments.

Income Taxes

The Blackstone Holdings partnerships and certain of their subsidiaries operate in the U.S. as partnerships for U.S. federal income tax purposes and generally as corporate entities in non-U.S. jurisdictions. Accordingly, these entities in some cases are subject to New York City unincorporated business taxes or non-U.S. income taxes. In addition, certain of the wholly-owned subsidiaries of the Partnership and the Blackstone Holdings partnerships will be subject to federal, state and local corporate income taxes at the entity level and the related tax provision attributable to the Partnership's share of this income is reflected in the consolidated financial statements.

Income taxes are accounted for using the asset and liability method of accounting. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis, using tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current and deferred tax liabilities are recorded within Accounts Payable, Accrued Expenses and Other Liabilities in the Consolidated Statements of Financial Position.

Blackstone analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Partnership determines that uncertainties in tax positions exist, a reserve is established. Blackstone recognizes accrued interest and penalties related to uncertain tax positions in General, Administrative, and Other expenses within the Consolidated Statements of Operations.

Blackstone records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process: (a) determination is made whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (b) those tax positions that meet the more-likely-than-not threshold are recognized as the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

Net Income (Loss) Per Common Unit

Basic Income (Loss) Per Common Unit is calculated by dividing Net Income (Loss) Attributable to The Blackstone Group L.P. by the weighted-average number of common units and unvested participating common units outstanding for the period. Diluted Income (Loss) Per Common Unit reflects the assumed conversion of all dilutive securities. Diluted Income (Loss) Per Common Unit excludes the anti-dilutive effect of unvested deferred restricted common units and Blackstone Holdings Partnership Units.

Prior to December 31, 2009, certain common unit holders were entitled to priority distributions. Basic and Diluted Net Income (Loss) Per Common Unit—Common Units Entitled to Priority Distributions and Common Units Not Entitled Priority Distributions for 2009 is calculated by dividing total undistributed loss allocated to common unitholders entitled to priority distributions and not entitled to priority distributions by the weighted-average number of common units entitled to priority distributions, including unvested participating common units due to their equivalent distribution rights, and common units not entitled to priority distributions, respectively. Diluted Net Income (Loss) Per Common Unit excludes the anti-dilutive effect of unvested deferred restricted common units and Blackstone Holdings Partnership Units. As a result of the expiration on December 31, 2009 of the distribution priority previously accorded to certain holders of Blackstone common units, the Partnership no longer has two classes of equity, resulting in the calculation of Basic and Diluted Net Income (Loss) Per Common Unit as noted above for the current reporting period.

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 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 counterparty 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 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 Consolidated Statements of Financial Condition.

Derivative Instruments

The Partnership recognizes all derivatives as assets or liabilities on its 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 General, Administrative and Other in the Consolidated Statements of Operations. 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.

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. The fair value of the derivative instrument is reflected within Other Assets in the Consolidated Statements of Financial Condition.

For freestanding derivative contracts, the Partnership presents changes in fair value in current period earnings. Changes in the fair value of derivative instruments held by consolidated Blackstone Funds are reflected in Net Gains from Funds Investment Activities or, where derivative instruments are held by the Partnership, within Investment Income (Loss), in the Consolidated Statements of Operations. The fair value of freestanding derivative assets are recorded within Investments and freestanding derivative liabilities are recorded within Accounts Payable, Accrued Expenses and Other Liabilities in the Consolidated Statements of Financial Condition.

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 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 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. 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 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. In addition, an entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. 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 December 2011, the FASB issued a deferral of the effective date for certain disclosures relating to the comprehensive income, specifically with respect to the presentation of reclassifications of items out of accumulated other comprehensive income. The deferral is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. 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. The amended guidance is not expected to have a material impact on the Partnership's financial statements.

In December 2011, the FASB issued guidance to enhance disclosures about financial instruments and derivative instruments that are either (a) offset or (b) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset. Under the amended guidance, an entity is required to disclose quantitative information relating to recognized assets and liabilities that are offset or subject to an enforceable master netting arrangement or similar agreement, including (a) the gross amounts of those recognized assets and liabilities, (b) the amounts offset to determine the net amount presented in the statement of financial position, and (c) the net amount presented in the statement of financial position. With respect to amounts subject to an enforceable master netting arrangement or similar agreement which are not offset, disclosure is required of (a) the amounts related to recognized financial instruments and other derivative instruments, (b) the amount related to financial collateral (including cash collateral), and (c) the overall net amount after considering amounts that have not been offset. The guidance is effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods and retrospective application is required. As the amendments are limited to disclosure only, adoption is not expected to have a material impact on the Partnership's financial statements.
