Risks Related to Our Business

Difficult market conditions can adversely affect our business in many ways, including by reducing the value or performance of the investments made by our investment funds, reducing the ability of our investment funds to raise or deploy capital and reducing the volume of the transactions involving our financial advisory business, each of which could materially reduce our revenue and cash flow and adversely affect our financial condition.

Our business is materially affected by conditions in the global financial markets and economic conditions or events throughout the world that are outside our control, including but not limited to changes in interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws (including laws relating to taxation), trade barriers, commodity prices, currency exchange rates and controls and national and international political circumstances (including wars, terrorist acts or security operations). These factors may affect the level and volatility of securities prices and the liquidity and the value of investments, and we may not be able to or may choose not to manage our exposure to these market conditions and/or other events. In the event of a market downturn each of our businesses could be affected in different ways.

For example, the unprecedented turmoil in the global financial markets during 2008 and 2009 provoked significant volatility of securities prices, contraction in the availability of credit and the failure of a number of companies, including leading financial institutions, had a significant material adverse effect on our investment businesses, particularly our private equity and real estate businesses. During that period, many economies around the world, including the U.S. economy, experienced significant declines in employment, household wealth, and lending. Those events led to a significantly diminished availability of credit and an increase in the cost of financing. The lack of credit materially hindered the initiation of new, large-sized transactions for our private equity and real estate segments and adversely impacted our operating results in those periods. While the adverse effects of that period have abated, there continue to be lingering signs of economic weakness such as relatively high levels of unemployment in major markets such as the U.S. and Europe, and financial institutions have not yet provided debt financing in amounts and on the terms commensurate with what they provided prior to 2008.

Our funds may be affected by reduced opportunities to exit and realize value from their investments, by lower than expected returns on investments made prior to the deterioration of the credit markets and by the fact that we may not be able to find suitable investments for the funds to effectively deploy capital, which could adversely affect our ability to raise new funds. During periods of difficult market conditions or slowdowns (which may be across one or more industries, sectors or geographies), our funds’ portfolio companies may experience adverse operating performance, decreased revenues, financial losses, difficulty in obtaining access to financing and increased funding costs. Negative financial results in our investment funds’ portfolio companies may result in lower investment returns for our investment funds, which could materially and adversely affect our ability to raise new funds as well as our operating results and cash flow. To the extent the operating performance of those portfolio companies (as well as valuation multiples) do not improve or other portfolio companies experience adverse operating performance, our investment funds may sell those assets at values that are less than we projected or even a loss, thereby significantly affecting those investment funds’ performance and consequently our operating results and cash flow. During such periods of weakness, our investment funds’ portfolio companies may also have difficulty expanding their businesses and operations or meeting their debt service obligations or other expenses as they become due, including expenses payable to us. Furthermore, such negative market conditions could potentially result in a portfolio company entering bankruptcy proceedings, thereby potentially resulting in a complete loss of the fund’s investment in such portfolio company and a significant negative impact to the investment fund’s performance and consequently our operating results and cash flow, as well as to our reputation. In addition, negative market conditions would also increase the risk of default with respect to investments held by our investment funds that have significant debt investments, such as our credit-oriented funds. Although market conditions improved during 2010, we are unable to predict whether economic and market conditions will continue to improve. Even if such conditions do improve broadly and significantly over the long term, adverse conditions and/or other events in particular sectors may cause our performance to suffer further.

Our operating performance may also be adversely affected by our fixed costs and other expenses and the possibility that we would be unable to scale back other costs within a time frame sufficient to match any decreases in revenue relating to changes in market and economic conditions. In order to reduce expenses in the face of a difficult economic environment, we may need to cut back or eliminate the use of certain services or service providers, or terminate the employment of a significant number of our personnel that, in each case, could be important to our business and without which our operating results could be adversely affected.

In addition, our financial advisory business can be materially affected by conditions in the global economy and various financial markets. For example, revenues generated by our financial advisory business are directly related to the volume and value of the transactions in which we are involved. During periods of unfavorable market or economic conditions, the volume and value of mergers and acquisitions transactions may decrease, thereby reducing the demand for our financial advisory services and increasing price competition among financial services companies seeking such engagements.

Changes in the debt financing markets could negatively impact the ability of our funds and their portfolio companies to obtain attractive financing or re-financing for their investments and could increase the cost of such financing if it is obtained, which could lead to lower-yielding investments and potentially decreasing our net income.

Any recurrence of the significant contraction in the market for debt financing that occurred in 2008 and 2009 or other adverse change to us relating to the terms of such debt financing with, for example, higher rates, higher equity requirements, and/or more restrictive covenants, particularly in the area of acquisition financings for private equity and real estate transactions, would have a material adverse impact on our business. In the event that our funds are unable to obtain committed debt financing for potential acquisitions or can only obtain debt at an increased interest rate or on unfavorable terms, our funds may have difficulty completing otherwise profitable acquisitions or may generate profits that are lower than would otherwise be the case, either of which could lead to a decrease in the investment income earned by us. Similarly, our funds’ portfolio companies regularly utilize the corporate debt markets in order to obtain financing for their operations. To the extent that the credit markets render such financing difficult to obtain or more expensive, this may negatively impact the operating performance of those portfolio companies and, therefore, the investment returns on our funds. In addition, to the extent that the markets make it difficult or impossible to refinance debt that is maturing in the near term, some of our portfolio companies may be unable to repay such debt at maturity and may be forced to sell assets, undergo a recapitalization or seek bankruptcy protection.

A decline in the pace or size of investment by our private equity and real estate funds or an increase in the amount of transaction and monitoring fees we share with our investors would result in our receiving less revenue from transaction and monitoring fees.

The transaction and monitoring fees that we earn are driven in part by the pace at which our private equity and real estate funds make investments and the size of those investments. Any decline in that pace or the size of such investments would reduce our transaction and monitoring fees. Many factors could cause such a decline in the pace of investment, including the inability of our investment professionals to identify attractive investment opportunities, competition for such opportunities among other potential acquirers, decreased availability of capital on attractive terms and our failure to consummate identified investment opportunities because of business, regulatory or legal complexities and adverse developments in the U.S. or global economy or financial markets. For example, the more limited financing options for large private equity and real estate investments resulting from the credit market dislocations in 2008 and 2009 have reduced the pace and size of investments by our private equity and real estate funds. In addition, we have confronted and expect to continue to confront requests from a variety of investors and groups representing investors to increase the percentage of transaction and monitoring fees we share with our investors. To the extent we accommodate such requests, and in certain cases we have and we expect to continue to do so, it would result in a decrease in the amount of fee revenue we earn.

Our revenue, net income and cash flow are all highly variable, which may make it difficult for us to achieve steady earnings growth on a quarterly basis and may cause the price of our common units to decline.

Our revenue, net income and cash flow are all highly variable. For example, our cash flow may fluctuate significantly due to the fact that we receive carried interest from our carry funds only when investments are realized and achieve a certain preferred return. In addition, transaction fees received by our carry funds and fees received by our advisory business can vary significantly from quarter to quarter. We may also experience fluctuations in our results, including our revenue and net income, from quarter to quarter due to a number of other factors, including changes in the values of our funds’ investments, changes in the amount of distributions, dividends or interest paid in respect of investments, changes in our operating expenses, the degree to which we encounter competition and general economic and market conditions. Such variability may lead to volatility in the trading price of our common units and cause our results for a particular period not to be indicative of our performance in a future period. It may be difficult for us to achieve steady growth in net income and cash flow on a quarterly basis, which could in turn lead to large adverse movements in the price of our common units or increased volatility in our common unit price generally.

The timing and receipt of carried interest generated by our carry funds is uncertain and will contribute to the volatility of our results. Carried interest depends on our carry funds’ performance and opportunities for realizing gains, which may be limited. It takes a substantial period of time to identify attractive investment opportunities, to raise all the funds needed to make an investment and then to realize the cash value (or other proceeds) of an investment through a sale, public offering, recapitalization or other exit. Even if an investment proves to be profitable, it may be several years before any profits can be realized in cash (or other proceeds). We cannot predict when, or if, any realization of investments will occur. In addition, upon the realization of a profitable investment by any of our carry funds and prior to us receiving any carried interest in respect of that investment, 100% of the proceeds of that investment must generally be paid to the investors in that carry fund until they have recovered certain fees and expenses and achieved a certain return on all realized investments by that carry fund as well as a recovery of any unrealized losses. If we were to have a realization event in a particular quarter, it may have a significant impact on our results for that particular quarter which may not be replicated in subsequent quarters. We recognize revenue on investments in our investment funds based on our allocable share of realized and unrealized gains (or losses) reported by such investment funds, and a decline in realized or unrealized gains, or an increase in realized or unrealized losses, would adversely affect our revenue and possibly cash flow, which could further increase the volatility of our quarterly results. Because our carry funds have preferred return thresholds to investors that need to be met prior to Blackstone receiving any carried interest, substantial declines in the carrying value of the investment portfolios of a carry fund can significantly delay or eliminate any carried interest distributions paid to us in respect of that fund since the value of the assets in the fund would need to recover to their aggregate cost basis plus the preferred return over time before we would be entitled to receive any carried interest from that fund.

With respect to most of our funds of hedge funds and credit-oriented and real estate debt funds structured like hedge funds, our incentive income is paid annually or semi-annually, and the varying frequency of these payments will contribute to the volatility of our cash flow. Furthermore, we earn this incentive income only if the net asset value of a fund has increased or, in the case of certain funds, increased beyond a particular return threshold. Certain of these funds also have “high water marks” whereby we do not earn incentive income during a particular period even though the fund had positive returns in such period as a result of losses in prior periods. If one of these funds experiences losses, we will not be able to earn incentive income from the fund until it surpasses the previous high water mark. The incentive income we earn is therefore dependent on the net asset value of the fund, which could lead to significant volatility in our results.

We also earn a portion of our revenue from financial advisory engagements, and in many cases we are not paid until the successful consummation of the underlying transaction, restructuring or closing of the fund. As a result, our financial advisory revenue is highly dependent on market conditions and the decisions and actions of our clients, interested third parties and governmental authorities. If a transaction, restructuring or funding is not

22

Table of Contents

consummated, we often do not receive any financial advisory fees other than the reimbursement of certain out-of-pocket expenses, despite the fact that we may have devoted considerable resources to these transactions.

Because our revenue, net income and cash flow can be highly variable from quarter to quarter and year to year, we do not provide any guidance regarding our expected quarterly and annual operating results. The lack of guidance may affect the expectations of public market analysts and could cause increased volatility in our common unit price.

Adverse economic and market conditions may adversely affect our liquidity position, which could adversely affect our business operations in the future.

We use cash to (a) provide capital to facilitate the growth of our existing businesses, which principally includes funding our general partner and co-investment commitments to our funds; (b) provide capital for business expansion; (c) pay operating expenses and other obligations as they arise; (d) fund capital expenditures; (e) service interest payments on our debt and repay debt; (f) pay income taxes; and (g) make distributions to our unitholders and the holders of Blackstone Holdings Partnership Units. In addition to the cash we received in connection with our IPO, our $600 million debt offering in August 2009 and our $400 million debt offering in September 2010, our principal sources of cash are: (a) Net Fee Related Earnings from Operations, (b) Realized Performance Fees net of related profit sharing interests that are included in Compensation and (c) Blackstone Investment Income related to its investments in liquid funds and its net realized investment income on its illiquid investments. We have also entered into a $1 billion revolving credit facility with a final maturity date of March 23, 2013. Our long-term debt totaled $1 billion in borrowings from the 2009 and 2010 bond issuances and we had no borrowings outstanding against our $1 billion revolving credit facility. At the end of 2010, we had $588.6 million in cash, $1.1 billion invested in our Treasury cash management strategies, $285.2 million invested in liquid Blackstone funds and $1.6 billion invested in illiquid Blackstone funds.

If the global economy and conditions in the financing markets fail to improve or worsen, our fund investment performance could suffer, resulting in, for example, the payment of less or no carried interest to us. The payment of less or no carried interest could cause our cash flow from operations to significantly decrease, which could materially and adversely affect our liquidity position and the amount of cash we have on hand to conduct our operations. Having less cash on hand could in turn require us to rely on other sources of cash (such as the capital markets which may not be available to us on acceptable terms) to conduct our operations, which include, for example, funding significant general partner and co-investment commitments to our carry funds. Furthermore, during adverse economic and market conditions, we might not be able to renew all or part of our existing revolving credit facility or find alternate financing on commercially reasonable terms. As a result, our uses of cash may exceed our sources of cash, thereby potentially affecting our liquidity position.

We depend on our founder and other key senior managing directors and the loss of their services would have a material adverse effect on our business, results and financial condition.

We depend on the efforts, skill, reputations and business contacts of our founder, Stephen A. Schwarzman, our President and Chief Operating Officer, Hamilton E. James, our Vice Chairman, J. Tomilson Hill, and other key senior managing directors, the information and deal flow they and other senior managing directors generate during the normal course of their activities and the synergies among the diverse fields of expertise and knowledge held by our professionals. Accordingly, our success will depend on the continued service of these individuals, who are not obligated to remain employed with us. Several key senior managing directors have left the firm in the past and others may do so in the future, and we cannot predict the impact that the departure of any key senior managing director will have on our ability to achieve our investment objectives. The loss of the services of any of them could have a material adverse effect on our revenues, net income and cash flows and could harm our ability to maintain or grow assets under management in existing funds or raise additional funds in the future. We have historically relied in part on the interests of these professionals in the investment funds’ carried interest and incentive fees to discourage them from leaving the firm. However, to the extent our

23

Table of Contents

investment funds perform poorly, thereby reducing the potential for carried interest and incentive fees, their interests in carried interest and incentive fees become less valuable to them and become less effective as incentives for them to continue to be employed at Blackstone.

Our senior managing directors and other key personnel possess substantial experience and expertise and have strong business relationships with investors in our funds, clients and other members of the business community. As a result, the loss of these personnel could jeopardize our relationships with investors in our funds, our clients and members of the business community and result in the reduction of assets under management or fewer investment opportunities.

Our publicly traded structure may adversely affect our ability to retain and motivate our senior managing directors and other key personnel and to recruit, retain and motivate new senior managing directors and other key personnel, both of which could adversely affect our business, results and financial condition.

Our most important asset is our people, and our continued success is highly dependent upon the efforts of our senior managing directors and other professionals. Our future success and growth depends to a substantial degree on our ability to retain and motivate our senior managing directors and other key personnel and to strategically recruit, retain and motivate new talented personnel. Most of our current senior managing directors and other senior personnel have equity interests in our business that are primarily partnership units in Blackstone Holdings (as defined under “Part III. Item 13. Certain Relationships, Related Transactions and Director Independence—Blackstone Holdings Partnership Agreements”) and which entitle such personnel to cash distributions. However, the value of such Blackstone Holdings partnership units and the distributions in respect of these equity interests may not be sufficient to retain and motivate our senior managing directors and other key personnel, nor may they be sufficiently attractive to strategically recruit, retain and motivate new talented personnel. Moreover, prior to our IPO, many of our senior managing directors and other senior personnel had interests in each of our underlying businesses which may have entitled to them to a larger amount of cash distributions than they receive in respect of Blackstone Holdings partnership units.

Additionally, the retention of an increasingly larger portion of the Blackstone Holdings partnership units held by senior managing directors is not dependent upon their continued employment with us as those equity interests continue to vest as time passes. Moreover, the minimum retained ownership requirements and transfer restrictions to which these interests are subject in certain instances lapse over time, may not be enforceable in all cases and can be waived. There is no guarantee that the non-competition and non-solicitation agreements to which our senior managing directors are subject, together with our other arrangements with them, will prevent them from leaving us, joining our competitors or otherwise competing with us or that these agreements will be enforceable in all cases. In addition, these agreements will expire after a certain period of time, at which point each of our senior managing directors would be free to compete against us and solicit investors in our funds, clients and employees.

We might not be able to provide future senior managing directors with equity interests in our business to the same extent or with the same tax consequences from which our existing senior managing directors previously benefited. For example, if legislation were to be enacted by the U.S. Congress or any state or local governments to treat carried interest as ordinary income rather than as capital gain for tax purposes, such legislation would materially increase the amount of taxes that we and possibly our unitholders would be required to pay, thereby adversely affecting our ability to recruit, retain and motivate our current and future professionals. See “—Risks Related to United States Taxation—Our structure involves complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. Our structure also is subject to potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis.”

Alternatively, the value of the units we may issue senior managing directors at any given time may subsequently fall (as reflected in the market price of our common units), which could counteract the incentives we are seeking to induce in them. Therefore, in order to recruit and retain existing and future senior managing

24

Table of Contents

directors, we may need to increase the level of compensation that we pay to them. Accordingly, as we promote or hire new senior managing directors over time, we may increase the level of compensation we pay to our senior managing directors, which would cause our total employee compensation and benefits expense as a percentage of our total revenue to increase and adversely affect our profitability. In addition, issuance of equity interests in our business in the future to senior managing directors and other personnel would dilute public common unitholders.

We strive to maintain a work environment that reinforces our culture of collaboration, motivation and alignment of interests with investors. If we do not continue to develop and implement the right processes and tools to manage our changing enterprise and maintain this culture, our ability to compete successfully and achieve our business objectives could be impaired, which could negatively impact our business, financial condition and results of operations.

Our organizational documents do not limit our ability to enter into new lines of businesses, and we may expand into new investment strategies, geographic markets and businesses, each of which may result in additional risks and uncertainties in our businesses.

Our plan, to the extent that market conditions permit, is to grow our investment and financial advisory businesses and expand into new investment strategies, geographic markets and businesses. Our organizational documents do not limit us to the investment management and financial advisory businesses. Accordingly, we may pursue growth through acquisitions of other investment management or advisory companies, acquisitions of critical business partners or other strategic initiatives. In addition, we expect opportunities will arise to acquire other alternative or traditional asset managers. To the extent we make strategic investments or acquisitions, undertake other strategic initiatives or enter into a new line of business, we will face numerous risks and uncertainties, including risks associated with (a) the required investment of capital and other resources, (b) the possibility that we have insufficient expertise to engage in such activities profitably or without incurring inappropriate amounts of risk, (c) combining or integrating operational and management systems and controls and (d) the broadening of our geographic footprint, including the risks associated with conducting operations in non-U.S. jurisdictions. Entry into certain lines of business may subject us to new laws and regulations with which we are not familiar, or from which we are currently exempt, and may lead to increased litigation and regulatory risk. If a new business generates insufficient revenues or if we are unable to efficiently manage our expanded operations, our results of operations will be adversely affected. Our strategic initiatives may include joint ventures, in which case we will be subject to additional risks and uncertainties in that we may be dependent upon, and subject to liability, losses or reputational damage relating to systems, controls and personnel that are not under our control.

If we are unable to consummate or successfully integrate additional development opportunities, acquisitions or joint ventures, we may not be able to implement our growth strategy successfully.

Our growth strategy is based, in part, on the selective development or acquisition of asset management businesses, advisory businesses or other businesses complementary to our business where we think we can add substantial value or generate substantial returns. The success of this strategy will depend on, among other things: (a) the availability of suitable opportunities; (b) the level of competition from other companies that may have greater financial resources; (c) our ability to value potential development or acquisition opportunities accurately and negotiate acceptable terms for those opportunities; (d) our ability to identify and enter into mutually beneficial relationships with venture partners; (e) and our ability to successfully integrate and oversee the operations of the new businesses. If we are not successful in implementing our growth strategy, our business, financial results and the market price for our common units may be adversely affected.

The U.S. Congress recently considered legislation that, if enacted, would have (a) for taxable years beginning ten years after the date of enactment, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (b) taxed individual holders of common units with respect to certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, we could incur a material increase in our tax liability and a substantial portion of our income could be taxed at a higher rate to the individual holders of our common units.

On May 28, 2010, the U.S. House of Representatives passed legislation that would have, in general, treated income and gains, including gain on sale, attributable to an interest in an investment services partnership interest, or “ISPI”, as income subject to a new blended tax rate that is higher than the capital gains rate applicable to such income under current law, except to the extent such ISPI would have been considered under the legislation to be a qualified capital interest. Our common units that you hold and the interests that we hold in entities that are entitled to receive carried interest would likely have been classified as ISPIs for purposes of this legislation. In June 2010, the U.S. Senate considered but did not pass legislation that is generally similar to the legislation passed by the U.S. House of Representatives. It is unclear whether or when the U.S. Congress will reconsider similar legislation or what provisions will be included in any final legislation if enacted.

The House bill provided that, for taxable years beginning ten years after the date of enactment, income derived with respect to an ISPI that is not a qualified capital interest and that is treated as ordinary income under the rules discussed above would not meet the qualifying income requirements under the publicly traded partnership rules. Therefore, if similar legislation were to be enacted, following such ten-year period, we would be precluded from qualifying as a partnership for U.S. federal income tax purposes or be required to hold all such ISPIs through corporations. If we were taxed as a U.S. corporation or held all ISPIs through U.S. corporations, our effective tax rate could increase significantly. The federal statutory rate for corporations is currently 35%. In addition, we could be subject to increased state and local taxes. Furthermore, you could be subject to tax on our conversion into a corporation or any restructuring required in order for us to hold our ISPIs through a corporation.

The Obama administration has indicated that it supports the adoption of the May 28, 2010 legislation or legislation that similarly changes the treatment of carried interest for U.S. federal income tax purposes. In its published revenue proposal for 2012, the Obama administration proposed that the current law regarding the treatment of carried interest be changed to subject such income to ordinary income tax (which would be taxed at a higher rate than the proposed blended rate under the House legislation). The Obama administration proposed similar changes in its published revenue proposals for 2010 and 2011.

Over the past several years, a number of similar legislative proposals have been introduced and, in certain cases, have been passed by the U.S. House of Representatives. In 2007, legislation was introduced in the U.S. Congress that would have taxed as corporations publicly traded partnerships that directly or indirectly derived income from investment advisor or asset management services. In 2008, the U.S. House of Representatives passed a bill that would have generally (a) treated carried interest as non-qualifying income under the tax rules applicable to publicly traded partnerships, which could have precluded us from qualifying as a partnership for U.S. federal income tax purposes, and (b) taxed carried interest as ordinary income for U.S. federal income taxes, rather than in accordance with the character of income derived by the underlying fund. In December 2009, the U.S. House of Representatives passed substantially similar legislation. Such legislation would have taxed carried interest as ordinary income starting in the year of enactment. The legislation passed by the House in December 2009 and certain other versions of the proposed legislation contained a transition rule that may have delayed the applicability of certain aspects of the legislation for a partnership that is a publicly traded partnership on the date of enactment of the legislation.

States and other jurisdictions have also considered legislation to increase taxes with respect to carried interest. For example, in 2010, the New York State Assembly passed a bill, which could have caused a non-resident of New York who holds our common units to be subject to New York state income tax on carried

26

Table of Contents

interest earned by entities in which we hold an indirect interest, thereby requiring the non-resident to file a New York state income tax return reporting such carried interest income. This legislation would have been retroactive to January 1, 2010. It is unclear whether or when similar legislation will be enacted. Finally, because of widespread state budget deficits, several states are evaluating ways to subject partnerships to entity level taxation through the imposition of state income, franchise or other forms of taxation. If any state were to impose a tax upon us as an entity, our distribution to you would be reduced.

The potential requirement to convert our financial statements from being prepared in conformity with accounting principles generally accepted in the United States of America to International Financial Reporting Standards may strain our resources and increase our annual expenses.

As a public entity, the SEC may require in the future that we report our financial results under International Financial Reporting Standards (“IFRS”) instead of under accounting principles generally accepted in the United States of America (“U.S. GAAP”). IFRS is a set of accounting principles that has been gaining acceptance on a worldwide basis. These standards are published by the London-based International Accounting Standards Board (“IASB”) and are more focused on objectives and principles and less reliant on detailed rules than U.S. GAAP. Today, there remain significant and material differences in several key areas between U.S. GAAP and IFRS which would affect Blackstone. Additionally, U.S. GAAP provides specific guidance in classes of accounting transactions for which equivalent guidance in IFRS does not exist. The adoption of IFRS is highly complex and would have an impact on many aspects and operations of Blackstone, including but not limited to financial accounting and reporting systems, internal controls, taxes, borrowing covenants and cash management. It is expected that a significant amount of time, internal and external resources and expenses over a multi-year period would be required for this conversion.

Operational risks may disrupt our businesses, result in losses or limit our growth.

We rely heavily on our financial, accounting and other data processing systems. If any of these systems do not operate properly or are disabled, we could suffer financial loss, a disruption of our businesses, liability to our investment funds, regulatory intervention or reputational damage. In addition, we operate in businesses that are highly dependent on information systems and technology. Our information systems and technology may not continue to be able to accommodate our growth, and the cost of maintaining such systems may increase from its current level. Such a failure to accommodate growth, or an increase in costs related to such information systems, could have a material adverse effect on us.

Furthermore, we depend on our headquarters in New York City, where most of our personnel are located, for the continued operation of our business. A disaster or a disruption in the infrastructure that supports our businesses, including a disruption involving electronic communications or other services used by us or third parties with whom we conduct business, or directly affecting our headquarters, could have a material adverse impact on our ability to continue to operate our business without interruption. Our disaster recovery programs may not be sufficient to mitigate the harm that may result from such a disaster or disruption. In addition, insurance and other safeguards might only partially reimburse us for our losses, if at all.

Finally, we rely on third-party service providers for certain aspects of our business, including for certain information systems and technology and administration of our hedge funds. Any interruption or deterioration in the performance of these third parties or failures of their information systems and technology could impair the quality of the funds’ operations and could affect our reputation and hence adversely affect our businesses.

Extensive regulation of our businesses affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus could result in additional burdens on our business. Legislative or regulatory changes could adversely affect us.

Our asset management and financial advisory businesses are subject to extensive regulation. We are subject to regulation, including periodic examinations, by governmental and self regulatory organizations in the

27

Table of Contents

jurisdictions in which we operate around the world. Many of these regulators, including U.S. and foreign government agencies and self-regulatory organizations, as well as state securities commissions in the United States, are empowered to conduct investigations and administrative proceedings that can result in fines, suspensions of personnel or other sanctions, including censure, the issuance of cease-and-desist orders or the suspension or expulsion of a broker-dealer or investment adviser from registration or memberships. Even if an investigation or proceeding did not result in a sanction or the sanction imposed against us or our personnel by a regulator were small in monetary amount, the adverse publicity relating to the investigation, proceeding or imposition of these sanctions could harm our reputation and cause us to lose existing clients or fail to gain new asset management or financial advisory clients. In addition, we regularly rely on exemptions from various requirements of the U.S. Securities Act of 1933, as amended, or “Securities Act,” the Exchange Act, the U.S. Investment Company Act of 1940, as amended, or “1940 Act,” and the U.S. Employee Retirement Income Security Act of 1974, as amended, in conducting our asset management activities. These exemptions are sometimes highly complex and may in certain circumstances depend on compliance by third parties whom we do not control. If for any reason these exemptions were to become unavailable to us, we could become subject to regulatory action or third party claims and our business could be materially and adversely affected. See “—Risks Related to Our Organizational Structure—If The Blackstone Group L.P. were deemed an “investment company” under the 1940 Act, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business”. Lastly, the requirements imposed by our regulators are designed primarily to ensure the integrity of the financial markets and to protect investors in our investment funds and are not designed to protect our common unitholders. Consequently, these regulations often serve to limit our activities and impose burdensome compliance requirements.

Regulatory changes in the United States could adversely affect our business.

As a result of the financial crisis and highly publicized financial scandals, investors have exhibited concerns over the integrity of the U.S. financial markets and the regulatory environment in which we operate in the United States. There has been an active debate over the appropriate extent of regulation and oversight of private investment funds and their managers. In addition, we may be adversely affected as a result of new or revised legislation or regulations imposed by the SEC or other U.S. governmental regulatory authorities or self-regulatory organizations that supervise the financial markets. We also may be adversely affected by changes in the interpretation or enforcement of existing laws and rules by these governmental authorities and self-regulatory organizations.

On July 21, 2010, President Obama signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) which imposes significant new regulations on almost every aspect of the U.S. financial services industry, including aspects of our business. Among other things, the Dodd-Frank Act includes the following provisions which could have an adverse impact on our ability to conduct our business:

Table of Contents

In June 2010, the SEC approved Rule 206(4)-5 under the Advisers Act regarding “pay to play” practices by investment advisers involving campaign contributions and other payments to government clients and elected officials able to exert influence on such clients. The rule prohibits investment advisers from providing advisory services for compensation to a government client for two years, subject to very limited exceptions, after the investment adviser, its senior executives or its personnel involved in soliciting investments from government entities make contributions to certain candidates and officials in position to influence the hiring of an investment adviser by such government client. Advisers are required to implement compliance policies designed, among other matters, to track contributions by certain of the adviser’s employees and engagements of third parties that solicit government entities and to keep certain records in order to enable the SEC to determine compliance with the rule. Any failure on our part to comply with the rule could expose us to significant penalties and reputational damage. In addition, there have been similar rules on a state level regarding “pay to play” practices by investment advisers.

In September 2010, California enacted legislation, which became effective on January 1, 2011, requiring placement agents who solicit funds from the California state retirement systems, such as the California Public Employees’ Retirement System and the California State Teachers’ Retirement System to register as lobbyists. In addition to increased reporting requirements, the legislation prohibits placement agents from receiving contingent compensation for soliciting investments from California state retirement systems. Moreover, other states or municipalities may consider similar legislation as that enacted in California or adopt regulations or procedures with similar effect. These types of measures could materially and adversely impact our fund placement business.

Recent regulatory changes in jurisdictions outside the United States could adversely affect our business.

Similar to the environment in the United States, the current environment in jurisdictions outside the United States in which we operate, in particular Europe, has become subject to further regulation. Governmental regulators and other authorities in Europe have proposed or implemented a number of initiatives and additional rules and regulations that could adversely affect our business.

In October 2010, the EU Council of Ministers adopted a directive to amend the revised Capital Requirements Directive, (“CRD III”), which, among other things, requires EU member states to introduce stricter control on remuneration of key employees and risk takers within specific credit institutions and investment firms. The FSA has implemented CRD III by amending its remuneration code, although the extent of the regulatory impact will differ depending on a firm’s size and the nature of its activities. We currently operate two entities in the United Kingdom—The Blackstone Group International Partners LLP and GSO Capital Partners International LLP—neither of which is subject to the quantitative provisions of the remuneration code. Accordingly, we do not currently anticipate that implementation of the FSA remuneration code will have any material impact on us.

In November 2010, the European Parliament voted to approve the EU Directive on Alternative Investment Fund Managers, which establishes a new EU regulatory regime for alternative investment fund managers, including private equity and hedge fund managers. The EU Directive generally applies to managers with a registered office in the EU (or managing an EU-based fund vehicle), as well as non EU-based managers, such as

29

Table of Contents

our affiliates, that market securities of alternative investment funds in the EU. In general, the EU Directive will have a staged implementation over a period of years beginning in mid-2013 for EU-based managers (or EU-based funds) and no later than 2018 for non-EU based managers marketing non-EU-based funds into the EU. Even as early as 2013, we will need to comply with certain provisions of the EU Directive in order to market our investment funds into Europe, including compliance with disclosure and transparency guidelines and asset-stripping restrictions (which prohibit distributions to shareholders for 24 months following closing of an acquisition). Blackstone’s compliance with the EU Directive, which can be no later than 2018, will subject it to a number of additional requirements, including rules relating to the remuneration of certain personnel (principally adopting the provisions of CRD III referred to above), certain capital requirements for alternative investment fund managers, leverage oversight for each investment fund, liquidity management, and retention of depositaries for each investment fund. Compliance with the requirements of the EU Directive will impose additional compliance burdens and expense for us and could reduce our operating flexibility and fund-raising opportunities.

In Denmark and Germany, legislative amendments have been adopted which may limit deductibility of interest and other financing expenses in companies in which our funds have invested or may invest in the future. In brief, the Danish legislative amendments generally entail that annual net financing expenses in excess of a certain threshold amount (approximately €2.9 million in 2010) will be limited on the basis of earnings before interest and taxes and/or asset tax values. According to the German legislative amendments, interest expenses exceeding the interest income of the same fiscal year may be deducted only up to 30% of the (adjusted) taxable earnings before interest, taxes, depreciation and amortization of the relevant German business (Betrieb) (subject to specific certain exemptions), while any additional non-deductible interest may, if at all, only be claimed in subsequent years. These measures will most likely adversely affect portfolio companies in those countries in which our funds have investments and limit the benefits of additional investments in those countries. Our investment businesses are subject to the risk that similar measures might be introduced in other countries in which our funds currently have investments or plan to invest in the future, or that other legislative or regulatory measures that negatively affect their respective portfolio investments might be promulgated in any of the countries in which they invest. Blackstone’s non-U.S. advisory entities are, to the extent required, registered with the relevant regulatory authority of the jurisdiction in which the advisory entity is domiciled. In addition, we voluntarily participate in several transparency initiatives, including those organized by the Private Equity Growth Capital Council, the British Private Equity and Venture Capital Association and others calling for the reporting of information concerning companies in which certain of our funds have investments. The reporting related to such initiatives may divert the attention of our personnel and the management teams of our portfolio companies. Moreover, sensitive business information relating to us or our portfolio companies could be publicly released.

Our use of leverage to finance our business will expose us to substantial risks, which are exacerbated by our funds’ use of leverage to finance investments.

We intend to use borrowings to finance our business operations as a public company. For example, in August 2009, we issued $600 million of ten-year senior notes at a rate of 6.625% per annum, and in September 2010, we issued $400 million of ten-year senior notes at a rate of 5.875% per annum. Borrowing to finance our businesses exposes us to the typical risks associated with the use of leverage, including those discussed below under “—Dependence on significant leverage in investments by our funds could adversely affect our ability to achieve attractive rates of return on those investments”. In order for us to utilize leverage to finance our business, we are dependent on financial institutions such as global banks extending credit to us on terms that are reasonable to us. There is no guarantee that such institutions will continue to extend credit to us or renew any existing credit agreements we may have with them, or that we will be able to refinance outstanding notes when they mature. We have a credit facility which provides for revolving credit borrowings that has a final maturity date of March 23, 2013. As borrowings under the facility or any other indebtedness mature, we may be required to either refinance them by entering into a new facility, which could result in higher borrowing costs, or issuing equity, which would dilute existing unitholders. We could also repay them by using cash on hand, cash provided by our continuing operations or cash from the sale of our assets. We could have difficulty entering into new facilities or issuing equity in the future on attractive terms, or at all. These risks are exacerbated by our funds’ use of leverage to finance investments.

Table of Contents

We are subject to substantial litigation risks and may face significant liabilities and damage to our professional reputation as a result of litigation allegations and negative publicity.

The investment decisions we make in our asset management business and the activities of our investment professionals on behalf of portfolio companies of our carry funds may subject them and us to the risk of third-party litigation arising from investor dissatisfaction with the performance of those investment funds, the activities of our portfolio companies and a variety of other litigation claims. For example, from time to time we and our portfolio companies have been subject to class action suits by shareholders in public companies that we have agreed to acquire that challenge our acquisition transactions and attempt to enjoin them.

In addition, to the extent investors in our investment funds suffer losses resulting from fraud, gross negligence, willful misconduct or other similar misconduct, investors may have remedies against us, our investment funds, our senior managing directors or our affiliates under the federal securities law and/or state law. While the general partners and investment advisers to our investment funds, including their directors, officers, other employees and affiliates, are generally indemnified to the fullest extent permitted by law with respect to their conduct in connection with the management of the business and affairs of our investment funds, such indemnity does not extend to actions determined to have involved fraud, gross negligence, willful misconduct or other similar misconduct.

Our financial advisory activities may also subject us to the risk of liabilities to our clients and third parties, including our clients’ stockholders, under securities or other laws in connection with corporate transactions on which we render advice.

If any lawsuits were brought against us and resulted in a finding of substantial legal liability, it could materially adversely affect our business, financial condition or results of operations or cause significant reputational harm to us, which could seriously harm our business. We depend to a large extent on our business relationships and our reputation for integrity and high-caliber professional services to attract and retain investors and advisory clients and to pursue investment opportunities for our carry funds. As a result, allegations of improper conduct by private litigants or regulators, whether the ultimate outcome is favorable or unfavorable to us, as well as negative publicity and press speculation about us, our investment activities or the private equity industry in general, whether or not valid, may harm our reputation, which may be more damaging to our business than to other types of businesses.

Employee misconduct could harm us by impairing our ability to attract and retain clients and subjecting us to significant legal liability and reputational harm. Fraud and other deceptive practices or other misconduct at our portfolio companies could harm performance.

There is a risk that our employees could engage in misconduct that adversely affects our business. We are subject to a number of obligations and standards arising from our asset management business and our authority over the assets managed by our asset management business. The violation of these obligations and standards by any of our employees would adversely affect our clients and us. Our business often requires that we deal with confidential matters of great significance to companies in which we may invest or our financial advisory clients. If our employees were improperly to use or disclose confidential information, we could suffer serious harm to our reputation, financial position and current and future business relationships. It is not always possible to detect or deter employee misconduct, and the extensive precautions we take to detect and prevent this activity may not be effective in all cases. If one of our employees were to engage in misconduct or were to be accused of such misconduct, our business and our reputation could be adversely affected.

We will also be adversely affected if there is misconduct by senior management of portfolio companies in which our funds invest. Such misconduct might undermine our due diligence efforts with respect to such companies and it might negatively affect the valuation of a fund’s investments.

In recent years, the U.S. Department of Justice and the U.S. Securities and Exchange Commission have devoted greater resources to enforcement of the Foreign Corrupt Practices Act (“FCPA”). In addition, the

31

Table of Contents

United Kingdom has recently significantly expanded the reach of its anti-bribery laws. While we have developed and implemented policies and procedures designed to ensure strict compliance by us and our personnel with the FCPA, such policies and procedures may not be effective in all instances to prevent violations. Any determination that we have violated the FCPA or other applicable anti-corruption laws could subject us to, among other things, civil and criminal penalties, material fines, profit disgorgement, injunctions on future conduct, securities litigation and a general loss of investor confidence, any one of which could adversely affect our business prospects, financial position or the market value of our common units.

Risks Related to Our Asset Management Business

Poor performance of our investment funds would cause a decline in our revenue, income and cash flow, may obligate us to repay carried interest previously paid to us, and could adversely affect our ability to raise capital for future investment funds.

In the event that any of our investment funds were to perform poorly, our revenue, income and cash flow would decline because the value of our assets under management would decrease, which would result in a reduction in management fees, and our investment returns would decrease, resulting in a reduction in the carried interest and incentive fees we earn. Moreover, we could experience losses on our investments of our own principal as a result of poor investment performance by our investment funds. Furthermore, if, as a result of poor performance of later investments in a carry fund’s life, the fund does not achieve certain investment returns for the fund over its life, we will be obligated to repay the amount by which carried interest that was previously distributed to us exceeds amounts to which we are ultimately entitled.

Poor performance of our investment funds could make it more difficult for us to raise new capital. Investors in carry funds might decline to invest in future investment funds we raise and investors in hedge funds or other investment funds might withdraw their investments as a result of poor performance of the investment funds in which they are invested. Investors and potential investors in our funds continually assess our investment funds’ performance, and our ability to raise capital for existing and future investment funds and avoid excessive redemption levels will depend on our investment funds’ continued satisfactory performance. Accordingly, poor fund performance may deter future investment in our funds and thereby decrease the capital invested in our funds and ultimately, our management fee income. Alternatively, in the face of poor fund performance, investors could demand lower fees or fee concessions for existing or future funds which would likewise decrease our revenue. A significant number of fund sponsors have recently decreased the amount of fees they charged investors for managing existing or successor funds as a direct result of poor fund performance.

Our asset management business depends in large part on our ability to raise capital from third party investors. If we are unable to raise capital from third party investors, we would be unable to collect management fees or deploy their capital into investments and potentially collect transaction fees or carried interest, which would materially reduce our revenue and cash flow and adversely affect our financial condition.

Our ability to raise capital from third party investors depends on a number of factors, including certain factors that are outside our control. Certain factors, such as the performance of the stock market or the asset allocation rules or regulations or investment policies to which such third party investors are subject, could inhibit or restrict the ability of third party investors to make investments in our investment funds or the asset classes in which our investment funds invest. For example, during 2008 and 2009, many third party investors that invest in alternative assets and have historically invested in our investment funds experienced significant volatility in valuations of their investment portfolios, including a significant decline in the value of their overall private equity, real estate, venture capital and hedge fund portfolios, which affected our ability to raise capital from them. Coupled with a lack of realizations during that period from their existing private equity and real estate portfolios, many of these investors were left with disproportionately outsized remaining commitments to a number of investment funds, which significantly limited their ability to make new commitments to third party managed investment funds such as those managed by us. Although economic conditions have improved and many investors have increased the amount of commitments they are making to alternative investment funds,

32

Table of Contents

there is no assurance that this will continue. Moreover, as some existing investors cease or significantly curtail making commitments to alternative investment funds, we may need to identify and attract new investors in order to maintain or increase the size of our investment funds. There are no assurances that we can find or secure commitments from those new investors. For instance, we will soon raise capital for our seventh global real estate opportunity fund and if economic conditions were to deteriorate or if we are unable to find new investors, we might raise less than our desired amount for that fund. Moreover, as we seek to expand into other asset classes, such as funds that focus on the clean technology asset class, we may be unable to raise a sufficient amount of capital to adequately support such businesses. If we are unable to successfully raise capital, it could materially reduce our revenue and cash flow and adversely affect our financial condition.

In addition, in connection with raising new funds or making further investments in existing funds, we negotiate terms for such funds and investments with existing and potential investors. The outcome of such negotiations could result in our agreement to terms that are materially less favorable to us than for prior funds we have managed or funds managed by our competitors. Such terms could restrict our ability to raise investment funds with investment objectives or strategies that compete with existing funds, add additional expenses and obligations for us in managing the fund or increase our potential liabilities, all of which could ultimately reduce our revenues. In addition, certain institutional investors have publicly criticized certain fund fee and expense structures, including management fees and transaction and advisory fees. Although we have no obligation to modify any of our fees with respect to our existing funds, we may experience pressure to do so in our funds. For example, we have confronted and expect to continue to confront requests from a variety of investors and groups representing investors to decrease fees, which could result in a reduction in the fees and carried interest and incentive fees we earn.

Valuation methodologies for certain assets in our funds can be subject to significant subjectivity and the fair value of assets established pursuant to such methodologies may never be realized, which could result in significant losses for our funds.

There are often no readily ascertainable market prices for illiquid investments in our private equity, real estate and certain of our credit-oriented funds. We determine the value of the investments of each of our private equity, real estate and credit-oriented funds at least quarterly based on the fair value of such investments. The fair value of investments of a private equity, real estate or credit-oriented fund is generally determined using several methodologies described in the investment funds’ valuation policies.

Investments for which market prices are not observable include private investments in the equity of operating companies or real estate properties. Fair values of such 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. In determining fair values of real estate investments, we also consider projected operating cash flows, sales of comparable assets, replacement costs and capitalization rates (“cap rates”) analyses. 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. Private investments may also be valued at cost for a period of time after an acquisition as the best indicator of fair value. These valuation methodologies involve a significant degree of management judgment.

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 matrixes, market transactions in comparable investments and various relationships between investments.

33

Table of Contents

The determination of fair value using these methodologies takes into consideration a range of factors including but not limited to the price at which the investment was acquired, the nature of the investment, local market conditions, trading values on public exchanges for comparable securities, current and projected operating performance and financing transactions subsequent to the acquisition of the investment. These valuation methodologies involve a significant degree of management judgment. For example, as to investments that we share with another sponsor, we may apply a different valuation methodology than the other sponsor does or derive a different value than the other sponsor has derived on the same investment. These differences might cause some investors to question our valuations.

Because there is significant uncertainty in the valuation of, or in the stability of the value of illiquid investments, the fair values of such investments as reflected in an investment fund’s net asset value do not necessarily reflect the prices that would actually be obtained by us on behalf of the investment fund when such investments are realized. Realizations at values significantly lower than the values at which investments have been reflected in prior fund net asset values would result in losses for the applicable fund, a decline in asset management fees and the loss of potential carried interest and incentive fees. Changes in values attributed to investments from quarter to quarter may result in volatility in the net asset values and results of operations and cash flow that we report from period to period. Also, a situation where asset values turn out to be materially different than values reflected in prior fund net asset values could cause investors to lose confidence in us, which would in turn result in difficulty in raising additional funds or redemptions from our hedge funds.

The historical returns attributable to our funds should not be considered as indicative of the future results of our funds or of our future results or of any returns expected on an investment in our common units.

The historical and potential future returns of the investment funds that we manage are not directly linked to returns on our common units. Therefore, any continued positive performance of the investment funds that we manage will not necessarily result in positive returns on an investment in our common units. However, poor performance of the investment funds that we manage would cause a decline in our revenue from such investment funds, and would therefore have a negative effect on our performance and in all likelihood the returns on an investment in our common units.

Moreover, with respect to the historical returns of our investment funds:

34

Table of Contents

In addition, future returns will be affected by the applicable risks described elsewhere in this Form 10-K, including risks of the industries and businesses in which a particular fund invests.

Dependence on significant leverage in investments by our funds could adversely affect our ability to achieve attractive rates of return on those investments.

Many of our carry funds’ investments rely heavily on the use of leverage, and our ability to achieve attractive rates of return on investments will depend on our ability to access sufficient sources of indebtedness at attractive rates. For example, in many private equity investments, indebtedness may constitute approximately 70% or more of a portfolio company’s or real estate asset’s total debt and equity capitalization, including debt that may be incurred in connection with the investment. The absence of available sources of sufficient senior debt financing for extended periods of time could therefore materially and adversely affect our private equity and real estate businesses. In addition, an increase in either the general levels of interest rates or in the risk spread demanded by sources of indebtedness would make it more expensive to finance those businesses’ investments. Increases in interest rates could also make it more difficult to locate and consummate private equity investments because other potential buyers, including operating companies acting as strategic buyers, may be able to bid for an asset at a higher price due to a lower overall cost of capital or their ability to benefit from a higher amount of cost savings following the acquisition of the asset. In addition, a portion of the indebtedness used to finance private equity investments often includes high-yield debt securities issued in the capital markets. Availability of capital from the high-yield debt markets is subject to significant volatility, and there may be times when we might not be able to access those markets at attractive rates, or at all, when completing an investment.

Investments in highly leveraged entities are inherently more sensitive to declines in revenues, increases in expenses and interest rates and adverse economic, market and industry developments. The incurrence of a significant amount of indebtedness by an entity could, among other things:

As a result, the risk of loss associated with a leveraged entity is generally greater than for companies with comparatively less debt. For example, many investments consummated by private equity sponsors during 2005, 2006 and 2007 that utilized significant amounts of leverage subsequently experienced severe economic stress and, in certain cases, defaulted on their debt obligations due to a decrease in revenues and cash flow precipitated by the subsequent economic downturn during 2008 and 2009.

When our BCP and BREP funds’ existing portfolio investments reach the point when debt incurred to finance those investments mature in significant amounts and must be either repaid or refinanced, those investments may materially suffer if they have generated insufficient cash flow to repay maturing debt and there is insufficient capacity and availability in the financing markets to permit them to refinance maturing debt on

35

Table of Contents

satisfactory terms, or at all. If a limited availability of financing for such purposes were to persist for an extended period of time, when significant amounts of the debt incurred to finance our private equity and real estate funds’ existing portfolio investments came due, these funds could be materially and adversely affected.

Many of the hedge funds in which our funds of hedge funds invest and our credit-oriented funds and CLOs may choose to use leverage as part of their respective investment programs and regularly borrow a substantial amount of their capital. The use of leverage poses a significant degree of risk and enhances the possibility of a significant loss in the value of the investment portfolio. A fund may borrow money from time to time to purchase or carry securities or may enter into derivative transactions (such as total return swaps) with counterparties that have embedded leverage. The interest expense and other costs incurred in connection with such borrowing may not be recovered by appreciation in the securities purchased or carried and will be lost—and the timing and magnitude of such losses may be accelerated or exacerbated—in the event of a decline in the market value of such securities. Gains realized with borrowed funds may cause the fund’s net asset value to increase at a faster rate than would be the case without borrowings. However, if investment results fail to cover the cost of borrowings, the fund’s net asset value could also decrease faster than if there had been no borrowings.

Increases in interest rates could also decrease the value of fixed-rate debt investments that our investment funds make.

Any of the foregoing circumstances could have a material adverse effect on our financial condition, results of operations and cash flow.

The asset management business is intensely competitive.

The asset management business is intensely competitive, with competition based on a variety of factors, including investment performance, the quality of service provided to clients, investor liquidity and willingness to invest, fund terms (including fees), brand recognition and business reputation. Our asset management business competes with a number of private equity funds, specialized investment funds, hedge funds, funds of hedge funds and other sponsors managing pools of capital, as well as corporate buyers, traditional asset managers, commercial banks, investment banks and other financial institutions (including sovereign wealth funds). A number of factors serve to increase our competitive risks:

36

Table of Contents

We may lose investment opportunities in the future if we do not match investment prices, structures and terms offered by competitors. Alternatively, we may experience decreased rates of return and increased risks of loss if we match investment prices, structures and terms offered by competitors. Moreover, if we are forced to compete with other alternative asset managers on the basis of price, we may not be able to maintain our current fund fee and carried interest terms. We have historically competed primarily on the performance of our funds, and not on the level of our fees or carried interest relative to those of our competitors. However, there is a risk that fees and carried interest in the alternative investment management industry will decline, without regard to the historical performance of a manager. Fee or carried interest income reductions on existing or future funds, without corresponding decreases in our cost structure, would adversely affect our revenues and profitability.

In addition, the attractiveness of our investment funds relative to investments in other investment products could decrease depending on economic conditions. This competitive pressure could adversely affect our ability to make successful investments and limit our ability to raise future investment funds, either of which would adversely impact our business, revenue, results of operations and cash flow.

The due diligence process that we undertake in connection with investments by our investment funds may not reveal all facts that may be relevant in connection with an investment.

Before making investments in private equity and other investments, we conduct due diligence that we deem reasonable and appropriate based on the facts and circumstances applicable to each investment. When conducting due diligence, we may be required to evaluate important and complex business, financial, tax, accounting, environmental and legal issues. Outside consultants, legal advisors, accountants and investment banks may be involved in the due diligence process in varying degrees depending on the type of investment. Nevertheless, when conducting due diligence and making an assessment regarding an investment, we rely on the resources available to us, including information provided by the target of the investment and, in some circumstances, third-party investigations. The due diligence investigation that we will carry out with respect to any investment opportunity may not reveal or highlight all relevant facts (including fraud) that may be necessary or helpful in evaluating such investment opportunity. Moreover, such an investigation will not necessarily result in the investment being successful.

In connection with the due diligence that our funds of hedge funds conduct in making and monitoring investments in third party hedge funds, we rely on information supplied by third party hedge funds or by service providers to such third party hedge funds. The information we receive from them may not be accurate or complete and therefore we may not have all the relevant facts necessary to properly assess and monitor our funds’ investment in a particular hedge fund.

37

Table of Contents

Our asset management activities involve investments in relatively high-risk, illiquid assets, and we may fail to realize any profits from these activities for a considerable period of time or lose some or all of our principal investments.

Many of our investment funds invest in securities that are not publicly traded. In many cases, our investment funds may be prohibited by contract or by applicable securities laws from selling such securities for a period of time. Our investment funds will generally not be able to sell these securities publicly unless their sale is registered under applicable securities laws, or unless an exemption from such registration is available. The ability of many of our investment funds, particularly our BCP funds, to dispose of investments is heavily dependent on the public equity markets. For example, the ability to realize any value from an investment may depend upon the ability to complete an initial public offering of the portfolio company in which such investment is held. Even if the securities are publicly traded, large holdings of securities can often be disposed of only over a substantial length of time, exposing the investment returns to risks of downward movement in market prices during the intended disposition period. Accordingly, under certain conditions, our investment funds may be forced to either sell securities at lower prices than they had expected to realize or defer—potentially for a considerable period of time—sales that they had planned to make. We have made and expect to continue to make significant principal investments in our current and future investment funds. Contributing capital to these investment funds is risky, and we may lose some or the entire principal amount of our investments.

We have engaged in large-sized investments, which involve certain complexities and risks that are not encountered in small and medium-sized investments.

Our BCP and BREP funds have invested and plan to continue to invest in large transactions. The size of these investments involves certain complexities and risks that are not encountered in small- and medium-sized investments. For example, larger transactions may be more difficult to finance, and exiting larger deals may present challenges in many cases. In addition, larger transactions may entail greater scrutiny by regulators, labor unions and other third parties.

Larger transactions may be structured as “consortium transactions” due to the size of the investment and the amount of capital required to be invested. A consortium transaction involves an equity investment in which two or more private equity firms serve together or collectively as equity sponsors. We participated in a significant number of consortium transactions in prior years due to the increased size of many of the transactions in which we were involved. Consortium transactions generally entail a reduced level of control by Blackstone over the investment because governance rights must be shared with the other private equity investors. Accordingly, we may not be able to control decisions relating to the investment, including decisions relating to the management and operation of the company and the timing and nature of any exit, which could result in the risks described in “—Our investment funds make investments in companies that we do not control.”

Any of these factors could increase the risk that our larger investments could be less successful. The consequences to our investment funds of an unsuccessful larger investment could be more severe given the size of the investment.

We often pursue investment opportunities that involve business, regulatory, legal or other complexities.

As an element of our investment style, we may pursue unusually complex investment opportunities. This can often take the form of substantial business, regulatory or legal complexity that would deter other investment managers. Our tolerance for complexity presents risks, as such transactions can be more difficult, expensive and time-consuming to finance and execute; it can be more difficult to manage or realize value from the assets acquired in such transactions; and such transactions sometimes entail a higher level of regulatory scrutiny or a greater risk of contingent liabilities. Any of these risks could harm the performance of our funds.

Our investment funds make investments in companies that we do not control.

Investments by most of our investment funds will include debt instruments and equity securities of companies that we do not control. Such instruments and securities may be acquired by our investment funds

38

Table of Contents

through trading activities or through purchases of securities from the issuer. In addition, our private equity and real estate funds may acquire minority equity interests (particularly in consortium transactions, as described in “—We have engaged in large-sized investments, which involve certain complexities and risks that are not encountered in small and medium-sized investments”) and may also dispose of a portion of their majority equity investments in portfolio companies over time in a manner that results in the investment funds retaining a minority investment. Those investments will be subject to the risk that the company in which the investment is made may make business, financial or management decisions with which we do not agree or that the majority stakeholders or the management of the company may take risks or otherwise act in a manner that does not serve our interests. If any of the foregoing were to occur, the values of investments by our investment funds could decrease and our financial condition, results of operations and cash flow could suffer as a result.

We expect to make investments in companies that are based outside of the United States, which may expose us to additional risks not typically associated with investing in companies that are based in the United States.

Many of our investment funds generally invest a significant portion of their assets in the equity, debt, loans or other securities of issuers located outside the United States, and we expect that international investments will increase as a proportion of certain of our funds’ portfolios in the future. Investments in non-U.S. securities involve certain factors not typically associated with investing in U.S. securities, including risks relating to:

There can be no assurance that adverse developments with respect to such risks will not adversely affect our assets that are held in certain countries or the returns from these assets.

We may not have sufficient cash to pay back “clawback” obligations if and when they are triggered under the governing agreements with our investors.

If, at the end of the life of a carry fund (or earlier with respect to certain of our real estate funds), as a result of diminished performance of later investments in any carry fund’s life, the carry fund has not achieved investment returns that (in most cases) exceed the preferred return threshold or (in all cases) the general partner receives in excess of 20% (10% or 15% in the case of certain of our credit-oriented and real estate debt carry funds) of the fund’s net profits over the life of the fund, we will be obligated to repay an amount equal to the extent to which carried interest that was previously distributed to us exceeds the amounts to which we are ultimately entitled. This obligation is known as a clawback obligation and is an obligation of any person who directly received such carried interest, including us and our employees who participate in our carried interest

39

Table of Contents

plans. Although a portion of any distributions by us to our unitholders may include any carried interest received by us, we do not intend to seek fulfillment of any clawback obligation by seeking to have our unitholders return any portion of such distributions attributable to carried interest associated with any clawback obligation. The clawback obligation operates with respect to a given carry fund’s own net investment performance only and performance fees of other funds are not netted for determining this contingent obligation. To the extent one or more clawback obligations were to occur for any one or more carry funds, we might not have available cash at the time such clawback obligation is triggered to repay the carried interest and satisfy such obligation. If we were unable to repay such carried interest, we would be in breach of the governing agreements with our investors and could be subject to liability. Moreover, although a clawback obligation is several, the governing agreements of most of our funds provide that to the extent another recipient of carried interest (such as a current or former employee) does not fund his or her respective share, then we and our employees who participate in such carried interest plans may have to fund additional amounts (generally up to an additional 50%) beyond what we actually received in carried interest, although we will retain the right to pursue any remedies that we have under such governing agreements against those carried interest recipients who fail to fund their obligations.

Investments by our investment funds will in most cases rank junior to investments made by others.

In most cases, the companies in which our investment funds invest will have indebtedness or equity securities, or may be permitted to incur indebtedness or to issue equity securities, that rank senior to our investment. By their terms, such instruments may provide that their holders are entitled to receive payments of dividends, interest or principal on or before the dates on which payments are to be made in respect of our investment. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a company in which an investment is made, holders of securities ranking senior to our investment would typically be entitled to receive payment in full before distributions could be made in respect of our investment. After repaying senior security holders, the company may not have any remaining assets to use for repaying amounts owed in respect of our investment. To the extent that any assets remain, holders of claims that rank equally with our investment would be entitled to share on an equal and ratable basis in distributions that are made out of those assets. Also, during periods of financial distress or following an insolvency, the ability of our investment funds to influence a company’s affairs and to take actions to protect their investments may be substantially less than that of the senior creditors.

Investors in our hedge funds may redeem their investments in these funds. In addition, the investment management agreements related to our separately managed accounts may permit the investor to terminate our management of such account on short notice. Lastly, investors in our other investment funds have the right to cause these investment funds to be dissolved. Any of these events would lead to a decrease in our revenues, which could be substantial.

Investors in our hedge funds may generally redeem their investments on an annual, semi-annual or quarterly basis following the expiration of a specified period of time when capital may not be withdrawn (typically between one and three years), subject to the applicable fund’s specific redemption provisions. In a declining market, the pace of redemptions and consequent reduction in our assets under management could accelerate. The decrease in revenues that would result from significant redemptions in our hedge funds could have a material adverse effect on our business, revenues, net income and cash flows.

We currently manage a significant portion of investor assets through separately managed accounts whereby we earn management and incentive fees, and we intend to continue to seek additional separately managed account mandates. The investment management agreements we enter into in connection with managing separately managed accounts on behalf of certain clients may be terminated by such clients on as little as 30 days’ prior written notice. In addition, the boards of directors of the investment management companies we manage, or the advisor in respect of the registered business development company we sub-advise, could terminate our advisory engagement of those companies, on as little as 30 days’ prior written notice. In the case of any such terminations, the management and incentive fees we earn in connection with managing such account or company would immediately cease, which could result in a significant adverse impact on our revenues.

Table of Contents

The governing agreements of all of our investment funds (with the exception of certain of our funds of hedge funds) provide that, subject to certain conditions, third-party investors in those funds will have the right to remove the general partner of the fund or to accelerate the liquidation date of the investment fund without cause by a simple majority vote, resulting in a reduction in management fees we would earn from such investment funds and a significant reduction in the amounts of total carried interest and incentive fees from those funds. Carried interest and incentive fees could be significantly reduced as a result of our inability to maximize the value of investments by an investment fund during the liquidation process or in the event of the triggering of a “clawback” obligation. Finally, the applicable funds would cease to exist. In addition, the governing agreements of our investment funds provide that in the event certain “key persons” in our investment funds do not meet specified time commitments with regard to managing the fund (for example, both of Stephen A. Schwarzman and Hamilton E. James in the case of our private equity funds), then investors in certain funds have the right to vote to terminate the investment period by a simple majority vote in accordance with specified procedures, accelerate the withdrawal of their capital on an investor-by-investor basis, or the fund’s investment period will automatically terminate and the vote of a simple majority of investors is required to restart it. In addition to having a significant negative impact on our revenue, net income and cash flow, the occurrence of such an event with respect to any of our investment funds would likely result in significant reputational damage to us.

In addition, because all of our investment funds have advisers that are registered under the Advisers Act, the management agreements of all of our investment funds would be terminated upon an “assignment,” without investor consent, of these agreements, which may be deemed to occur in the event these advisers were to experience a change of control. We cannot be certain that consents required for assignments of our investment management agreements will be obtained if a change of control occurs. In addition, with respect to our publicly traded closed-end mutual funds, each investment fund’s investment management agreement must be approved annually by the independent members of such investment fund’s board of directors and, in certain cases, by its stockholders, as required by law. Termination of these agreements would cause us to lose the fees we earn from such investment funds.

Third party investors in our investment funds with commitment-based structures may not satisfy their contractual obligation to fund capital calls when requested by us, which could adversely affect a fund’s operations and performance.

Investors in all of our carry funds (and certain of our hedge funds) make capital commitments to those funds that we are entitled to call from those investors at any time during prescribed periods. We depend on investors fulfilling their commitments when we call capital from them in order for those funds to consummate investments and otherwise pay their obligations (for example, management fees) when due. We have not had investors fail to honor capital calls to any meaningful extent. Any investor that did not fund a capital call would generally be subject to several possible penalties, including having a significant amount of its existing investment forfeited in that fund. However, the impact of the penalty is directly correlated to the amount of capital previously invested by the investor in the fund and if an investor has invested little or no capital, for instance early in the life of the fund, then the forfeiture penalty may not be as meaningful. Investors may also negotiate for lesser or reduced penalties at the outset of the fund, thereby inhibiting our ability to enforce the funding of a capital call. If investors were to fail to satisfy a significant amount of capital calls for any particular fund or funds, the operation and performance of those funds could be materially and adversely affected.

Certain policies and procedures implemented to mitigate potential conflicts of interest and address certain regulatory requirements may reduce the synergies across our various businesses.

Because of our various lines of asset management and advisory businesses, we will be subject to a number of actual and potential conflicts of interest and subject to greater regulatory oversight than that to which we would otherwise be subject if we had just one line of business. In addressing these conflicts and regulatory requirements across our various businesses, we have implemented certain policies and procedures (for example, information walls) that may reduce the positive synergies that we cultivate across these businesses. For example,

41

Table of Contents

we may come into possession of material non-public information with respect to issuers in which we may be considering making an investment or issuers that are our advisory clients. As a consequence, we may be precluded from providing such information or other ideas to our other businesses that might be of benefit to them.

Our failure to deal appropriately with conflicts of interest in our investment business could damage our reputation and adversely affect our businesses.

As we have expanded and as we continue to expand the number and scope of our businesses, we increasingly confront potential conflicts of interest relating to our funds’ investment activities. Certain of our funds may have overlapping investment objectives, including funds that have different fee structures, and potential conflicts may arise with respect to our decisions regarding how to allocate investment opportunities among those funds. For example, a decision to acquire material non-public information about a company while pursuing an investment opportunity for a particular fund gives rise to a potential conflict of interest when it results in our having to restrict the ability of other funds to take any action. Also, our decision to pursue a fund investment opportunity could preclude our ability to obtain a related advisory assignment, and vice versa. In addition, conflicts of interest may exist in the valuation of our investments and regarding decisions about the allocation of specific investment opportunities among us and our funds and the allocation of fees and costs among us, our funds and their portfolio companies. Lastly, in certain, infrequent instances we may purchase an investment alongside one of our investment funds or sell an investment to one of our investment funds and conflicts may arise in respect of the allocation, pricing and timing of such investments and the ultimate disposition of such investments. To the extent we failed to appropriately deal with any such conflicts, it could negatively impact our reputation and ability to raise additional funds or result in potential litigation against us.

Risk management activities may adversely affect the return on our funds’ investments.

When managing our exposure to market risks, we may (on our own behalf or on behalf of our funds) from time to time use forward contracts, options, swaps, caps, collars and floors or pursue other strategies or use other forms of derivative instruments to limit our exposure to changes in the relative values of investments that may result from market developments, including changes in prevailing interest rates, currency exchange rates and commodity prices. The success of any hedging or other derivative transactions generally will depend on our ability to correctly predict market changes, the degree of correlation between price movements of a derivative instrument, the position being hedged, the creditworthiness of the counterparty and other factors. As a result, while we may enter into a transaction in order to reduce our exposure to market risks, the transaction may result in poorer overall investment performance than if it had not been executed. Such transactions may also limit the opportunity for gain if the value of a hedged position increases.

Our real estate funds are subject to the risks inherent in the ownership and operation of real estate and the construction and development of real estate.

Investments in our real estate funds will be subject to the risks inherent in the ownership and operation of real estate and real estate related businesses and assets. These risks include those associated with the burdens of ownership of real property, general and local economic conditions, changes in supply of and demand for competing properties in an area (as a result, for instance, of overbuilding), fluctuations in the average occupancy and room rates for hotel properties, the financial resources of tenants, changes in building, environmental and other laws, energy and supply shortages, various uninsured or uninsurable risks, natural disasters, changes in government regulations (such as rent control), changes in real property tax rates, changes in interest rates, the reduced availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable, negative developments in the economy that depress travel activity, environmental liabilities, contingent liabilities on disposition of assets, terrorist attacks, war and other factors that are beyond our control. In addition, if our real estate funds acquire direct or indirect interests in undeveloped land or underdeveloped real

42

Table of Contents

property, which may often be non-income producing, they will be subject to the risks normally associated with such assets and development activities, including risks relating to the availability and timely receipt of zoning and other regulatory or environmental approvals, the cost and timely completion of construction (including risks beyond the control of our fund, such as weather or labor conditions or material shortages) and the availability of both construction and permanent financing on favorable terms.

Certain of our investment funds may invest in securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Such investments are subject to a greater risk of poor performance or loss.

Certain of our investment funds, especially our credit-oriented funds, may invest in business enterprises involved in work-outs, liquidations, spin-offs, reorganizations, bankruptcies and similar transactions and may purchase high risk receivables. An investment in such business enterprises entails the risk that the transaction in which such business enterprise is involved either will be unsuccessful, will take considerable time or will result in a distribution of cash or a new security the value of which will be less than the purchase price to the fund of the security or other financial instrument in respect of which such distribution is received. In addition, if an anticipated transaction does not in fact occur, the fund may be required to sell its investment at a loss. Investments in troubled companies may also be adversely affected by U.S. federal and state laws relating to, among other things, fraudulent conveyances, voidable preferences, lender liability and a bankruptcy court’s discretionary power to disallow, subordinate or disenfranchise particular claims. Investments in securities and private claims of troubled companies made in connection with an attempt to influence a restructuring proposal or plan of reorganization in a bankruptcy case may also involve substantial litigation. Because there is substantial uncertainty concerning the outcome of transactions involving financially troubled companies, there is a potential risk of loss by a fund of its entire investment in such company. Moreover, a major economic recession could have a materially adverse impact on the value of such securities. In addition, adverse publicity and investor perceptions, whether or not based on fundamental analysis, may also decrease the value and liquidity of securities rated below investment grade or otherwise adversely affect our reputation.

Certain of our fund investments may be concentrated in certain asset types or in a geographic region, which could exacerbate any negative performance of those funds to the extent those concentrated investments perform poorly.

The governing agreements of our investment funds contain only limited investment restrictions and only limited requirements as to diversification of fund investments, either by geographic region or asset type. For example, over 80% of the investments of our real estate funds (based on current fair values) are in office building and hotel assets. During periods of difficult market conditions or slowdowns in these sectors, the decreased revenues, difficulty in obtaining access to financing and increased funding costs experienced by our real estate funds may be exacerbated by this concentration of investments, which would result in lower investment returns for our real estate funds.

The financial projections of our portfolio companies could prove inaccurate.

Our funds generally establish the capital structure of portfolio companies on the basis of financial projections prepared by the management of such portfolio companies. These projected operating results will normally be based primarily on judgments of the management of the portfolio companies. In all cases, projections are only estimates of future results that are based upon assumptions made at the time that the projections are developed. General economic conditions, which are not predictable, along with other factors may cause actual performance to fall short of the financial projections that were used to establish a given portfolio company’s capital structure. Because of the leverage we typically employ in our investments, this could cause a substantial decrease in the value of our equity holdings in the portfolio company. The inaccuracy of financial projections could thus cause our funds’ performance to fall short of our expectations.

43

Table of Contents

Contingent liabilities could harm fund performance.

We may cause our funds to acquire an investment that is subject to contingent liabilities. Such contingent liabilities could be unknown to us at the time of acquisition or, if they are known to us, we may not accurately assess or protect against the risks that they present. Acquired contingent liabilities could thus result in unforeseen losses for our funds. In addition, in connection with the disposition of an investment in a portfolio company, a fund may be required to make representations about the business and financial affairs of such portfolio company typical of those made in connection with the sale of a business. A fund may also be required to indemnify the purchasers of such investment to the extent that any such representations are inaccurate. These arrangements may result in the incurrence of contingent liabilities by a fund, even after the disposition of an investment. Accordingly, the inaccuracy of representations and warranties made by a fund could harm such fund’s performance.

Our funds may be forced to dispose of investments at a disadvantageous time.

Our funds may make investments that they do not advantageously dispose of prior to the date the applicable fund is dissolved, either by expiration of such fund’s term or otherwise. Although we generally expect that investments will be disposed of prior to dissolution or be suitable for in-kind distribution at dissolution, and the general partners of the funds have only a limited ability to extend the term of the fund with the consent of fund investors or the advisory board of the fund, as applicable, our funds may have to sell, distribute or otherwise dispose of investments at a disadvantageous time as a result of dissolution. This would result in a lower than expected return on the investments and, perhaps, on the fund itself.

Hedge fund investments are subject to numerous additional risks.

Investments by our funds of hedge funds in other hedge funds, as well as investments by our credit-oriented and real estate debt hedge funds, are subject to numerous additional risks, including the following:

Risks Related to Our Financial Advisory Business

Financial advisory fees are not long-term contracted sources of revenue and are not predictable.

The fees earned by our financial advisory business are typically payable upon the successful completion of a particular transaction or restructuring. A decline in our financial advisory engagements or the market for advisory services would adversely affect our business.

Our financial advisory business operates in a highly competitive environment where typically there are no long-term contracted sources of revenue. Each revenue generating engagement typically is separately solicited, awarded and negotiated. In addition, many businesses do not routinely engage in transactions requiring our services. As a consequence, our fee-paying engagements with many clients are not predictable and high levels of financial advisory revenue in one quarter are not necessarily predictive of continued high levels of financial advisory revenue in future periods. In addition to the fact that most of our financial advisory engagements are

45

Table of Contents

single, non-recurring engagements, we lose clients each year as a result of a client’s decision to retain other financial advisors, the sale, merger or restructuring of a client, a change in a client’s senior management and various other causes. Moreover, in any given year our financial advisory engagements may be limited to a relatively smaller number of clients and an even smaller number of those clients may account for a disproportionate percentage of our financial advisory revenues in any such year. As a result, the adverse impact on our results of operations of one lost engagement or the failure of one transaction or restructuring on which we are advising to be completed could be significant. Revenue volumes in our financial advisory business tend to be affected by economic and capital market conditions, with greater merger activity—and therefore higher revenues in our Financial and Strategic Advisory Services business—generally resulting when the economy is growing, and more bankruptcies and restructurings—and therefore higher revenues in our Restructuring and Reorganization Advisory Services business—generally resulting in weak economic periods. Accordingly, our financial advisory revenue can fluctuate up or down considerably depending on economic conditions.

The fees earned by Park Hill Group, our fund placement business, are generally recognized by us for accounting purposes upon the successful subscription by an investor in a client’s fund and/or the closing of that fund. However, those fees are typically actually paid by a Park Hill Group client over a period of time (e.g., two to three years) following such successful subscription by an investor in a client’s fund and/or the closing of that fund with interest. There is a risk that during that period of time, Park Hill Group may not be able to collect on all or a portion of the fees Park Hill is due for the placement services it has already provided to such client. For instance, a Park Hill client’s fund may be liquidated prior to the time that all or a portion of the fees due to Park Hill for its placement services are due to be paid. Moreover, to the extent fewer assets are raised for funds or interest by investors in alternative asset funds declines, the fees earned by Park Hill Group would be adversely affected. During 2009, a difficult year for fund-raising for funds in the alternative asset class, Park Hill experienced a material decline in revenue due to fewer placement mandates and fewer assets being raised.

We face strong competition from other financial advisory firms.

The financial advisory industry is intensely competitive, and we expect it to remain so. We compete on the basis of a number of factors, including the quality of our employees, transaction execution, our products and services, innovation and reputation and price. We have always experienced intense competition over obtaining advisory mandates, and we may experience pricing pressures in our financial advisory business in the future as some of our competitors seek to obtain increased market share by reducing fees. Our primary competitors in our financial advisory business are large financial institutions, many of which have far greater financial and other resources and much broader client relationships than us and (unlike us) have the ability to offer a wide range of products, from loans, deposit taking and insurance to brokerage and a wide range of investment banking services, which may enhance their competitive position. They also have the ability to support investment banking, including financial advisory services, with commercial banking, insurance and other financial services and products in an effort to gain market share, which puts us at a competitive disadvantage and could result in pricing pressures that could materially adversely affect our revenue and profitability. In the current market environment, we are also seeing increased competition from independent boutique advisory firms focused primarily on mergers and acquisitions advisory and/or restructuring services. In addition, Park Hill Group operates in a highly competitive environment and the barriers to entry into the fund placement business are low.

Risks Related to Our Organizational Structure

Our common unitholders do not elect our general partner or vote on our general partner’s directors and have limited ability to influence decisions regarding our business.

Our general partner, Blackstone Group Management L.L.C., which is owned by our senior managing directors, manages all of our operations and activities. Blackstone Group Management L.L.C. has a board of directors that is responsible for the oversight of our business and operations. Our general partner’s board of directors is elected in accordance with its limited liability company agreement, where our senior managing directors have agreed that our founder, Stephen A. Schwarzman, will have the power to appoint and remove the

46

Table of Contents

directors of our general partner. The limited liability company agreement of our general partner provides that at such time as Mr. Schwarzman should cease to be a founder, Hamilton E. James will thereupon succeed Mr. Schwarzman as the sole founding member of our general partner, and thereafter such power will revert to the members of our general partner (our senior managing directors) holding a majority in interest in our general partner.

Our common unitholders do not elect our general partner or its board of directors and, unlike the holders of common stock in a corporation, have only limited voting rights on matters affecting our business and therefore limited ability to influence decisions regarding our business. Furthermore, if our common unitholders are dissatisfied with the performance of our general partner, they have little ability to remove our general partner. Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than two-thirds of the voting power of our outstanding common units and special voting units (including common units and special voting units held by the general partner and its affiliates) and we receive an opinion of counsel regarding limited liability matters. As of December 31, 2010, Blackstone Partners L.L.C., an entity wholly owned by our senior managing directors, had 69.4% of the voting power of The Blackstone Group L.P. limited partners. Therefore, our senior managing directors have the ability to remove or block any removal of our general partner and thus control The Blackstone Group L.P.

Blackstone personnel collectively own a controlling interest in us and will be able to determine the outcome of those few matters that may be submitted for a vote of the limited partners.

Our senior managing directors generally have sufficient voting power to determine the outcome of those few matters that may be submitted for a vote of the limited partners of the Blackstone Group L.P., including any attempt to remove our general partner.

Our common unitholders’ voting rights are further restricted by the provision in our partnership agreement stating that any common units held by a person that beneficially owns 20% or more of any class of The Blackstone Group L.P. common units then outstanding (other than our general partner and its affiliates, or a direct or subsequently approved transferee of our general partner or its affiliates) cannot be voted on any matter. In addition, our partnership agreement contains provisions limiting the ability of our common unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the ability of our common unitholders to influence the manner or direction of our management. Our partnership agreement also does not restrict our general partner’s ability to take actions that may result in our being treated as an entity taxable as a corporation for U.S. federal (and applicable state) income tax purposes. Furthermore, the common unitholders are not entitled to dissenters’ rights of appraisal under our partnership agreement or applicable Delaware law in the event of a merger or consolidation, a sale of substantially all of our assets or any other transaction or event. In addition, we have the right to acquire all of our then-outstanding common units if not more than 10% of our common units are held by persons other than our general partner and its affiliates.

As a result of these matters and the provisions referred to under “—Our common unitholders do not elect our general partner or vote on our general partner’s directors and have limited ability to influence decisions regarding our business”, our common unitholders may be deprived of an opportunity to receive a premium for their common units in the future through a sale of The Blackstone Group L.P., and the trading prices of our common units may be adversely affected by the absence or reduction of a takeover premium in the trading price.

We are a limited partnership and as a result fall within exceptions from certain corporate governance and other requirements under the rules of the New York Stock Exchange.

We are a limited partnership and fall within exceptions from certain corporate governance and other requirements of the rules of the New York Stock Exchange. Pursuant to these exceptions, limited partnerships may elect not to comply with certain corporate governance requirements of the New York Stock Exchange, including the requirements (a) that a majority of the board of directors of our general partner consist of

47

Table of Contents

independent directors, (b) that we have a nominating/corporate governance committee that is composed entirely of independent directors and (c) that we have a compensation committee that is composed entirely of independent directors. In addition, we are not required to hold annual meetings of our common unitholders. We will continue to avail ourselves of these exceptions. Accordingly, common unitholders generally do not have the same protections afforded to equityholders of entities that are subject to all of the corporate governance requirements of the New York Stock Exchange.

Potential conflicts of interest may arise among our general partner, its affiliates and us. Our general partner and its affiliates have limited fiduciary duties to us and our common unitholders, which may permit them to favor their own interests to the detriment of us and our common unitholders.

Conflicts of interest may arise among our general partner and its affiliates, on the one hand, and us and our common unitholders, on the other hand. As a result of these conflicts, our general partner may favor its own interests and the interests of its affiliates over the interests of our common unitholders. These conflicts include, among others, the following:

48

Table of Contents

See “Part III. Item 13. Certain Relationships, Related Transactions and Director Independence” and “Part III. Item 10. Directors, Executive Officers and Corporate Governance—Partnership Management and Governance—Conflicts Committee.”

Our partnership agreement contains provisions that reduce or eliminate duties (including fiduciary duties) of our general partner and limit remedies available to common unitholders for actions that might otherwise constitute a breach of duty. It will be difficult for a common unitholder to successfully challenge a resolution of a conflict of interest by our general partner or by its conflicts committee.

Our partnership agreement contains provisions that waive or consent to conduct by our general partner and its affiliates that might otherwise raise issues about compliance with fiduciary duties or applicable law. For example, our partnership agreement provides that when our general partner is acting in its individual capacity, as opposed to in its capacity as our general partner, it may act without any fiduciary obligations to us or our common unitholders whatsoever. When our general partner, in its capacity as our general partner, is permitted to or required to make a decision in its “sole discretion” or “discretion” or that it deems “necessary or appropriate” or “necessary or advisable,” then our general partner is entitled to consider only such interests and factors as it desires, including its own interests, and has no duty or obligation (fiduciary or otherwise) to give any consideration to any interest of or factors affecting us or any limited partners and will not be subject to any different standards imposed by the partnership agreement, the Delaware Limited Partnership Act or under any other law, rule or regulation or in equity. These modifications of fiduciary duties are expressly permitted by Delaware law. Hence, we and our common unitholders only have recourse and are able to seek remedies against our general partner if our general partner breaches its obligations pursuant to our partnership agreement. Unless our general partner breaches its obligations pursuant to our partnership agreement, we and our common unitholders do not have any recourse against our general partner even if our general partner were to act in a manner that was inconsistent with traditional fiduciary duties. Furthermore, even if there has been a breach of the obligations set forth in our partnership agreement, our partnership agreement provides that our general partner and its officers and directors are not liable to us or our common unitholders for errors of judgment or for any acts or omissions unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that the general partner or its officers and directors acted in bad faith or engaged in fraud or willful misconduct. These modifications are detrimental to the common unitholders because they restrict the remedies available to common unitholders for actions that without those limitations might constitute breaches of duty (including fiduciary duty).

Whenever a potential conflict of interest exists between us and our general partner, our general partner may resolve such conflict of interest. If our general partner determines that its resolution of the conflict of interest is on terms no less favorable to us than those generally being provided to or available from unrelated third parties or is fair and reasonable to us, taking into account the totality of the relationships between us and our general partner, then it will be presumed that in making this determination, our general partner acted in good faith. A common unitholder seeking to challenge this resolution of the conflict of interest would bear the burden of overcoming such presumption. This is different from the situation with Delaware corporations, where a conflict resolution by an interested party would be presumed to be unfair and the interested party would have the burden of demonstrating that the resolution was fair.

Also, if our general partner obtains the approval of the conflicts committee of our general partner, the resolution will be conclusively deemed to be fair and reasonable to us and not a breach by our general partner of any duties it may owe to us or our common unitholders. This is different from the situation with Delaware

49

Table of Contents

corporations, where a conflict resolution by a committee consisting solely of independent directors may, in certain circumstances, merely shift the burden of demonstrating unfairness to the plaintiff. Common unitholders, in purchasing our common units, are deemed as having consented to the provisions set forth in the partnership agreement, including provisions regarding conflicts of interest situations that, in the absence of such provisions, might be considered a breach of fiduciary or other duties under applicable state law. As a result, common unitholders will, as a practical matter, not be able to successfully challenge an informed decision by the conflicts committee. See “Part III. Item 10. Directors, Executive Officers and Corporate Governance—Partnership Management and Governance—Conflicts Committee.”

The control of our general partner may be transferred to a third party without common unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or consolidation without the consent of our common unitholders. Furthermore, at any time, the members of our general partner may sell or transfer all or part of their limited liability company interests in our general partner without the approval of the common unitholders, subject to certain restrictions as described elsewhere in this annual report. A new general partner may not be willing or able to form new investment funds and could form funds that have investment objectives and governing terms that differ materially from those of our current investment funds. A new owner could also have a different investment philosophy, employ investment professionals who are less experienced, be unsuccessful in identifying investment opportunities or have a track record that is not as successful as Blackstone’s track record. If any of the foregoing were to occur, we could experience difficulty in making new investments, and the value of our existing investments, our business, our results of operations and our financial condition could materially suffer.

We intend to pay regular distributions to our common unitholders, but our ability to do so may be limited by our holding partnership structure, applicable provisions of Delaware law and contractual restrictions.

Our current intention is to distribute to our common unitholders substantially all of The Blackstone Group L.P.’s net after-tax share of our annual Distributable Earnings in excess of amounts determined by our general partner to be necessary or appropriate to provide for the conduct of our business, to make appropriate investments in our business and our funds, to comply with applicable law, any of our debt instruments or other agreements, or to provide for future distributions to our unitholders for any ensuing quarter. The declaration and payment of any distributions will be at the sole discretion of our general partner, which may change our distribution policy at any time. The Blackstone Group L.P. is a holding partnership and has no material assets other than the ownership of the partnership units in Blackstone Holdings held through wholly owned subsidiaries. The Blackstone Group L.P. has no independent means of generating revenue. Accordingly, we intend to cause Blackstone Holdings to make distributions to its partners, including The Blackstone Group L.P.’s wholly-owned subsidiaries, to fund any distributions The Blackstone Group L.P. may declare on the common units. Distributable Earnings is a non-GAAP measure intended to show the amount of our net realized earnings.

Our ability to make cash distributions to our unitholders will depend on a number of factors, including among others general economic and business conditions, our strategic plans and prospects, our business and investment opportunities, our financial condition and operating results, working capital requirements and anticipated cash needs, contractual restrictions and obligations including fulfilling our current and future capital commitments, legal, tax and regulatory restrictions, restrictions and other implications on the payment of distributions by us to our common unitholders or by our subsidiaries to us and such other factors as our general partner may deem relevant.

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

Under the Delaware Limited Partnership Act, we may not make a distribution to a partner if after the distribution all our liabilities, other than liabilities to partners on account of their partnership interests and

50

Table of Contents

liabilities for which the recourse of creditors is limited to specific property of the partnership, would exceed the fair value of our assets. If we were to make such an impermissible distribution, any limited partner who received a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Limited Partnership Act would be liable to us for the amount of the distribution for three years. In addition, the terms of our revolving credit facility or other financing arrangements may from time to time include covenants or other restrictions that could constrain our ability to make distributions.

We expect to record significant net losses for a number of years as a result of the amortization of finite-lived intangible assets and non-cash equity-based compensation.

As part of the reorganization related to our initial public offering we acquired interests in our business from our predecessor owners. This transaction has been accounted for partially as a transfer of interests under common control and partially as an acquisition of non-controlling interests. We accounted for the acquisition of the non-controlling interests using the purchase method of accounting, and reflected the excess of the purchase price over the fair value of the tangible assets acquired and liabilities assumed as goodwill and other intangible assets on our statement of financial condition. As of December 31, 2010, we have recorded $779.3 million of finite-lived intangible assets (in addition to $1.7 billion of goodwill). We are amortizing these finite-lived intangibles over their estimated useful lives, which range between five and fifteen years, using the straight-line method. In addition, as part of the reorganization at the time of our IPO, Blackstone personnel received an aggregate of 827,516,625 Blackstone Holdings Partnership Units, of which 439,711,537 were unvested. The grant date fair value of the unvested Blackstone Holdings Partnership Units (which was $31) is being charged to expense as the Blackstone Holdings Partnership Units vest over the assumed service periods, which range up to eight years, on a straight-line basis. The amortization of these finite-lived intangible assets and of this non-cash equity-based compensation will increase our expenses substantially during the relevant periods.

We are required to pay our senior managing directors for most of the benefits relating to any additional tax depreciation or amortization deductions we may claim as a result of the tax basis step-up we received as part of the reorganization we implemented in connection with our IPO or receive in connection with future exchanges of our common units and related transactions.

As part of the reorganization we implemented in connection with our IPO, we purchased interests in our business from our pre-IPO owners. In addition, holders of partnership units in Blackstone Holdings (other than The Blackstone Group L.P.’s wholly owned subsidiaries), subject to the vesting and minimum retained ownership requirements and transfer restrictions set forth in the partnership agreements of the Blackstone Holdings partnerships, may up to four times each year (subject to the terms of the exchange agreement) exchange their Blackstone Holdings Partnership Units for The Blackstone Group L.P. common units on a one-for-one basis. A Blackstone Holdings limited partner must exchange one partnership unit in each of the four Blackstone Holdings partnerships to effect an exchange for a common unit. The purchase and subsequent exchanges are expected to result in increases in the tax basis of the tangible and intangible assets of Blackstone Holdings that otherwise would not have been available. These increases in tax basis may increase (for tax purposes) depreciation and amortization and therefore reduce the amount of tax that certain of The Blackstone Group L.P.’s wholly owned subsidiaries that are taxable as corporations for U.S. federal income tax purposes, which we refer to as the “corporate taxpayers,” would otherwise be required to pay in the future, although the IRS may challenge all or part of that tax basis increase, and a court could sustain such a challenge.

One of the corporate taxpayers has entered into a tax receivable agreement with our senior managing directors and other pre-IPO owners that provides for the payment by the corporate taxpayer to the counterparties of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the corporate taxpayers actually realize as a result of these increases in tax basis and of certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. In addition, additional tax receivable agreements have been executed, and others may continue to be executed, with newly admitted Blackstone senior managing directors and certain others who

receive Blackstone Holdings Partnership Units. This payment obligation is an obligation of the corporate taxpayer and not of Blackstone Holdings. As such, the cash distributions to public common unitholders may vary from holders of Blackstone Holdings units (held by Blackstone personnel and others) to the extent payments are made under the tax receivable agreements to selling holders of Blackstone Holdings units. As the payments reflect actual tax savings received by Blackstone entities, there may be a timing difference between the tax savings received by Blackstone entities and the cash payments to selling holders of Blackstone Holdings units. While the actual increase in tax basis, as well as the amount and timing of any payments under this agreement, will vary depending upon a number of factors, including the timing of exchanges, the price of our common units at the time of the exchange, the extent to which such exchanges are taxable and the amount and timing of our income, we expect that as a result of the size of the increases in the tax basis of the tangible and intangible assets of Blackstone Holdings, the payments that we may make under the tax receivable agreements will be substantial. The payments under a tax receivable agreement are not conditioned upon a tax receivable agreement counterparty’s continued ownership of us. We may need to incur debt to finance payments under the tax receivable agreement to the extent our cash resources are insufficient to meet our obligations under the tax receivable agreements as a result of timing discrepancies or otherwise.

Although we are not aware of any issue that would cause the IRS to challenge a tax basis increase, the tax receivable agreement counterparties will not reimburse us for any payments previously made under the tax receivable agreement. As a result, in certain circumstances payments to the counterparties under the tax receivable agreement could be in excess of the corporate taxpayers’ actual cash tax savings. The corporate taxpayers’ ability to achieve benefits from any tax basis increase, and the payments to be made under the tax receivable agreements, will depend upon a number of factors, as discussed above, including the timing and amount of our future income.

If The Blackstone Group L.P. were deemed an “investment company” under the 1940 Act, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business.

An entity will generally be deemed to be an “investment company” for purposes of the 1940 Act if: (a) it is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities; or (b) absent an applicable exemption, it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We believe that we are engaged primarily in the business of providing asset management and financial advisory services and not in the business of investing, reinvesting or trading in securities. We also believe that the primary source of income from each of our businesses is properly characterized as income earned in exchange for the provision of services. We hold ourselves out as an asset management and financial advisory firm and do not propose to engage primarily in the business of investing, reinvesting or trading in securities. Accordingly, we do not believe that The Blackstone Group L.P. is an “orthodox” investment company as defined in section 3(a)(1)(A) of the 1940 Act and described in clause (a) in the first sentence of this paragraph. Furthermore, The Blackstone Group L.P. does not have any material assets other than its equity interests in certain wholly owned subsidiaries, which in turn will have no material assets (other than intercompany debt) other than general partner interests in the Blackstone Holdings partnerships. These wholly owned subsidiaries are the sole general partners of the Blackstone Holdings partnerships and are vested with all management and control over the Blackstone Holdings partnerships. We do not believe the equity interests of The Blackstone Group L.P. in its wholly owned subsidiaries or the general partner interests of these wholly owned subsidiaries in the Blackstone Holdings partnerships are investment securities. Moreover, because we believe that the capital interests of the general partners of our funds in their respective funds are neither securities nor investment securities, we believe that less than 40% of The Blackstone Group L.P.’s total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis are comprised of assets that could be considered investment securities. Accordingly, we do not believe The Blackstone Group L.P. is an inadvertent investment company by virtue of the 40% test in section 3(a)(1)(C) of the 1940 Act as described in clause (b) in the first sentence of this paragraph. In addition, we believe The Blackstone Group L.P. is not an investment company under section 3(b)(1) of the 1940 Act because it is primarily engaged in a non-investment company business.

The 1940 Act and the rules thereunder contain detailed parameters for the organization and operation of investment companies. Among other things, the 1940 Act and the rules thereunder limit or prohibit transactions with affiliates, impose limitations on the issuance of debt and equity securities, generally prohibit the issuance of options and impose certain governance requirements. We intend to conduct our operations so that The Blackstone Group L.P. will not be deemed to be an investment company under the 1940 Act. If anything were to happen which would cause The Blackstone Group L.P. to be deemed to be an investment company under the 1940 Act, requirements imposed by the 1940 Act, including limitations on our capital structure, ability to transact business with affiliates (including us) and ability to compensate key employees, could make it impractical for us to continue our business as currently conducted, impair the agreements and arrangements between and among The Blackstone Group L.P., Blackstone Holdings and our senior managing directors, or any combination thereof, and materially adversely affect our business, financial condition and results of operations. In addition, we may be required to limit the amount of investments that we make as a principal or otherwise conduct our business in a manner that does not subject us to the registration and other requirements of the 1940 Act.

Risks Related to Our Common Units

Our common unit price may decline due to the large number of common units eligible for future sale and for exchange.

The market price of our common units could decline as a result of sales of a large number of common units in the market in the future or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell common units in the future at a time and at a price that we deem appropriate. We had a total of 343,303,073 voting common units outstanding as of February 18, 2011. Subject to the lock-up restrictions described below, we may issue and sell in the future additional common units. Limited partners of Blackstone Holdings own an aggregate of 640,170,462 Blackstone Holdings Partnership Units outstanding as of February 18, 2011. In connection with our initial public offering, we entered into an exchange agreement with holders of Blackstone Holdings Partnership Units (other than The Blackstone Group L.P.’s wholly owned subsidiaries) so that these holders, subject to the vesting and minimum retained ownership requirements and transfer restrictions set forth in the partnership agreements of the Blackstone Holdings partnerships, may up to four times each year (subject to the terms of the exchange agreement) exchange their Blackstone Holdings Partnership Units for The Blackstone Group L.P. common units on a one-for-one basis, subject to customary conversion rate adjustments for splits, unit distributions and reclassifications. A Blackstone Holdings limited partner must exchange one partnership unit in each of the four Blackstone Holdings partnerships to effect an exchange for a common unit. The common units we issue upon such exchanges would be “restricted securities,” as defined in Rule 144 under the Securities Act, unless we register such issuances. However, we have entered into a registration rights agreement with the limited partners of Blackstone Holdings that would require us to register these common units under the Securities Act. See “Part III. Item 13. Certain Relationships, Related Transactions and Director Independence—Transactions with Related Persons—Registration Rights Agreement”. While the partnership agreements of the Blackstone Holdings partnerships and related agreements contractually restrict the ability of Blackstone personnel to transfer the Blackstone Holdings Partnership Units or The Blackstone Group L.P. common units they hold and require that they maintain a minimum amount of equity ownership during their employ by us, these contractual provisions may lapse over time or be waived, modified or amended at any time.

In addition, in June 2007, we entered into an agreement with Beijing Wonderful Investments, an investment vehicle established and controlled by The People’s Republic of China, pursuant to which we sold to it 101,334,234 non-voting common units for $3.00 billion at a purchase price per common unit of $29.605. Beijing Wonderful Investments will be able to sell these common units subject to certain transfer restrictions. We have agreed to provide Beijing Wonderful Investments with registration rights to effect certain sales.

As of February 18, 2011, we had granted 30,571,950 outstanding deferred restricted common units and 15,460,142 outstanding deferred restricted Blackstone Holdings Partnership Units, which are subject to specified

53

Table of Contents

vesting requirements, to our non-senior managing director professionals and senior managing directors under our 2007 Equity Incentive Plan. The aggregate number of common units and Blackstone Holdings Partnership Units covered by our 2007 Equity Incentive Plan is increased on the first day of each fiscal year during its term by a number of units equal to the positive difference, if any, of (a) 15% of the aggregate number of common units and Blackstone Holdings Partnership Units outstanding on the last day of the immediately preceding fiscal year (excluding Blackstone Holdings Partnership Units held by The Blackstone Group L.P. or its wholly-owned subsidiaries) minus (b) the aggregate number of common units and Blackstone Holdings Partnership Units covered by our 2007 Equity Incentive Plan as of such date (unless the administrator of the 2007 Equity Incentive Plan should decide to increase the number of common units and Blackstone Holdings Partnership Units covered by the plan by a lesser amount). An aggregate of 157,046,304 additional common units and Blackstone Holdings Partnership Units were available for grant under our 2007 Equity Incentive Plan as of February 19, 2011. We have filed a registration statement and intend to file additional registration statements on Form S-8 under the Securities Act to register common units covered by our 2007 Equity Incentive Plan (including pursuant to automatic annual increases). Any such Form S-8 registration statement will automatically become effective upon filing. Accordingly, common units registered under such registration statement will be available for sale in the open market.

In addition, our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and options, rights, warrants and appreciation rights relating to partnership securities for the consideration and on the terms and conditions established by our general partner in its sole discretion without the approval of any limited partners. In accordance with the Delaware Limited Partnership Act and the provisions of our partnership agreement, we may also issue additional partnership interests that have certain designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to common units. Similarly, the Blackstone Holdings partnership agreements authorize the wholly owned subsidiaries of The Blackstone Group L.P. which are the general partners of those partnerships to issue an unlimited number of additional partnership securities of the Blackstone Holdings partnerships with such designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the Blackstone Holdings partnerships units, and which may be exchangeable for our common units.

The market price of our common units may be volatile, which could cause the value of your investment to decline.

Securities markets worldwide experience significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could reduce the market price of common units in spite of our operating performance. In addition, our operating results could be below the expectations of public market analysts and investors, and in response the market price of our common units could decrease significantly. You may be unable to resell your common units at or above the price you paid for them.

Risks Related to United States Taxation

Our structure involves complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. Our structure also is subject to potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis.

The U.S. federal income tax treatment of common unitholders depends in some instances on determinations of fact and interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. The U.S. federal income tax rules are constantly under review by persons involved in the legislative process, the U.S. Internal Revenue Service, or “IRS,” and the U.S. Treasury Department, frequently resulting in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations. The IRS pays close attention to the proper application of tax laws to partnerships. The present U.S. federal income tax treatment of an investment in our common units may be modified by administrative, legislative or judicial interpretation at any time, and any such action may affect

54

Table of Contents

investments and commitments previously made. Changes to the U.S. federal income tax laws and interpretations thereof could make it more difficult or impossible to meet the exception for us to be treated as a partnership for U.S. federal income tax purposes that is not taxable as a corporation (referred to as the “Qualifying Income Exception”), affect or cause us to change our investments and commitments, affect the tax considerations of an investment in us, change the character or treatment of portions of our income (including, for instance, the treatment of carried interest as ordinary income rather than capital gain) and adversely affect an investment in our common units. For example, as discussed above under “—The U.S. Congress recently considered legislation that, if enacted, would have (a) for taxable years beginning ten years after the date of enactment, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (b) taxed individual holders of common units with respect to certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, we could incur a material increase in our tax liability and a substantial portion of our income could be taxed at a higher rate to the individual holders of our common units”, the U.S. Congress recently considered various legislative proposals to treat all or part of the capital gain and dividend income that is recognized by an investment partnership and allocable to a partner affiliated with the sponsor of the partnership (i.e., a portion of the carried interest) as ordinary income to such partner for U.S. federal income tax purposes.

Our organizational documents and governing agreements permit our general partner to modify our amended and restated limited partnership agreement from time to time, without the consent of the common unitholders, to address certain changes in U.S. federal income tax regulations, legislation or interpretation. In some circumstances, such revisions could have a material adverse impact on some or all common unitholders. Moreover, we will apply certain assumptions and conventions in an attempt to comply with applicable rules and to report income, gain, deduction, loss and credit to common unitholders in a manner that reflects such common unitholders’ beneficial ownership of partnership items, taking into account variation in unitholder ownership interests during each taxable year because of trading activity. More specifically, our allocations of items of taxable income and loss between transferors and transferees of our units will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the unitholders in proportion to the number of units owned by each of them determined as of the opening of trading of our units on the New York Stock Exchange on the first business day of every month. As a result, a unitholder transferring units may be allocated income, gain, loss and deductions realized after the date of transfer. However, those assumptions and conventions may not be in compliance with all aspects of applicable tax requirements. It is possible that the IRS will assert successfully that the conventions and assumptions used by us do not satisfy the technical requirements of the Internal Revenue Code and/or Treasury regulations and could require that items of income, gain, deductions, loss or credit, including interest deductions, be adjusted, reallocated or disallowed in a manner that adversely affects common unitholders.

If we were treated as a corporation for U.S. federal income tax or state tax purposes, then our distributions to our common unitholders would be substantially reduced and the value of our common units would be adversely affected.

The value of our common units depends in part on our being treated as a partnership for U.S. federal income tax purposes, which requires that 90% or more of our gross income for every taxable year consist of qualifying income, as defined in Section 7704 of the Internal Revenue Code and that The Blackstone Group L.P. not be registered under the 1940 Act. Qualifying income generally includes dividends, interest, capital gains from the sale or other disposition of stocks and securities and certain other forms of investment income. We may not meet these requirements or current law may change so as to cause, in either event, us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject to U.S. federal income tax. Moreover, the anticipated after-tax benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes. We have not requested, and do not plan to request, a ruling from the IRS on this or any other matter affecting us.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate. Distributions to our common unitholders would generally be

55

Table of Contents

taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to you. Because a tax would be imposed upon us as a corporation, our distributions to our common unitholders would be substantially reduced, likely causing a substantial reduction in the value of our common units.

Current law may change, causing us to be treated as a corporation for U.S. federal or state income tax purposes or otherwise subjecting us to entity level taxation. See “—The U.S. Congress recently considered legislation that, if enacted, would have (a) for taxable years beginning ten years after the date of enactment, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (b) taxed individual holders of common units with respect to certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, we could incur a material increase in our tax liability and a substantial portion of our income could be taxed at a higher rate to the individual holders of our common units.” For example, because of widespread state budget deficits, several states are evaluating ways to subject partnerships to entity level taxation through the imposition of state income, franchise or other forms of taxation. If any state were to impose a tax upon us as an entity, our distributions to our common unitholders would be reduced.

Our common unitholders may be subject to U.S. federal income tax on their share of our taxable income, regardless of whether they receive any cash distributions from us.

As long as 90% of our gross income for each taxable year constitutes qualifying income as defined in Section 7704 of the Internal Revenue Code and we are not required to register as an investment company under the 1940 Act on a continuing basis, we will be treated, for U.S. federal income tax purposes, as a partnership and not as an association or a publicly traded partnership taxable as a corporation. Accordingly, each unitholder will be required to take into account its allocable share of items of income, gain, loss and deduction of the Partnership. Distributions to a unitholder will generally be taxable to the unitholder for U.S. federal income tax purposes only to the extent the amount distributed exceeds the unitholder’s tax basis in the unit. That treatment contrasts with the treatment of a shareholder in a corporation. For example, a shareholder in a corporation who receives a distribution of earnings from the corporation will generally report the distribution as dividend income for U.S. federal income tax purposes. In contrast, a holder of our units who receives a distribution of earnings from us will not report the distribution as dividend income (and will treat the distribution as taxable only to the extent the amount distributed exceeds the unitholder’s tax basis in the units), but will instead report the holder’s allocable share of items of our income for U.S. federal income tax purposes. As a result, our common unitholders may be subject to U.S. federal, state, local and possibly, in some cases, foreign income taxation on their allocable share of our items of income, gain, loss, deduction and credit (including our allocable share of those items of any entity in which we invest that is treated as a partnership or is otherwise subject to tax on a flow through basis) for each of our taxable years ending with or within your taxable year, regardless of whether or not a common unitholder receives cash distributions from us.

Our common unitholders may not receive cash distributions equal to their allocable share of our net taxable income or even the tax liability that results from that income. In addition, certain of our holdings, including holdings, if any, in a Controlled Foreign Corporation, or “CFC,” and a Passive Foreign Investment Company, or “PFIC,” may produce taxable income prior to the receipt of cash relating to such income, and common unitholders that are U.S. taxpayers will be required to take such income into account in determining their taxable income. In the event of an inadvertent termination of our partnership status for which the IRS has granted us limited relief, each holder of our common units may be obligated to make such adjustments as the IRS may require to maintain our status as a partnership. Such adjustments may require persons holding our common units to recognize additional amounts in income during the years in which they hold such units.

The Blackstone Group L.P.’s interest in certain of our businesses are held through Blackstone Holdings I/II GP Inc. or Blackstone Holdings IV GP L.P., which are treated as corporations for U.S. federal income tax purposes; such corporations may be liable for significant taxes and may create other adverse tax consequences, which could potentially adversely affect the value of your investment.

In light of the publicly traded partnership rules under U.S. federal income tax law and other requirements, The Blackstone Group L.P. holds its interest in certain of our businesses through Blackstone Holdings I/II GP Inc. or Blackstone Holdings IV GP L.P., which are treated as corporations for U.S. federal income tax purposes. Each such corporation could be liable for significant U.S. federal income taxes and applicable state, local and other taxes that would not otherwise be incurred, which could adversely affect the value of our common units.

Complying with certain tax-related requirements may cause us to invest through foreign or domestic corporations subject to corporate income tax or enter into acquisitions, borrowings, financings or arrangements we may not have otherwise entered into.

In order for us to be treated as a partnership for U.S. federal income tax purposes and not as an association or publicly traded partnership taxable as a corporation, we must meet the Qualifying Income Exception discussed above on a continuing basis and we must not be required to register as an investment company under the 1940 Act. In order to effect such treatment, we (or our subsidiaries) may be required to invest through foreign or domestic corporations subject to corporate income tax, or enter into acquisitions, borrowings, financings or other transactions we may not have otherwise entered into. This may adversely affect our ability to operate solely to maximize our cash flow.

Tax gain or loss on disposition of our common units could be more or less than expected.

If a holder of our common units sells the common units it holds, it will recognize a gain or loss equal to the difference between the amount realized and the adjusted tax basis in those common units. Prior distributions to such common unitholder in excess of the total net taxable income allocated to such common unitholder, which decreased the tax basis in its common units, will in effect become taxable income to such common unitholder if the common units are sold at a price greater than such common unitholder’s tax basis in those common units, even if the price is less than the original cost. A portion of the amount realized, whether or not representing gain, may be ordinary income to such common unitholder.

If we were not to make, or cause to be made, an otherwise available election under Section 754 of the Internal Revenue Code to adjust our asset basis or the asset basis of certain of the Blackstone Holdings partnerships, a holder of common units could be allocated more taxable income in respect of those common units prior to disposition than if such an election were made.

We currently do not intend to make, or cause to be made, an election to adjust asset basis under Section 754 of the Internal Revenue Code with respect to us, Blackstone Holdings III L.P. or Blackstone Holdings IV L.P. If no such election is made, there will generally be no adjustment to the basis of the assets of Blackstone Holdings III L.P. or Blackstone Holdings IV L.P. upon our acquisition of interests in Blackstone Holdings III L.P. or Blackstone Holdings IV L.P. in connection with our initial public offering, or to our assets or to the assets of Blackstone Holdings III L.P. or Blackstone Holdings IV L.P. upon a subsequent transferee’s acquisition of common units from a prior holder of such common units, even if the purchase price for those interests or units, as applicable, is greater than the share of the aggregate tax basis of our assets or the assets of Blackstone Holdings III L.P. or Blackstone Holdings IV L.P. attributable to those interests or units immediately prior to the acquisition. Consequently, upon a sale of an asset by us, Blackstone Holdings III L.P. or Blackstone Holdings IV L.P., gain allocable to a holder of common units could include built-in gain in the asset existing at the time we acquired those interests, or such holder acquired such units, which built-in gain would otherwise generally be eliminated if a Section 754 election had been made.

Non-U.S. persons face unique U.S. tax issues from owning common units that may result in adverse tax consequences to them.

In light of our investment activities, we will be treated as engaged in a U.S. trade or business for U.S. federal income tax purposes, which may cause some portion of our income to be treated as effectively connected income with respect to non-U.S. holders, or “ECI.” Moreover, dividends paid by an investment that we make in a real estate investment trust, or “REIT,” that are attributable to gains from the sale of U.S. real property interests and sales of certain investments in interests in U.S. real property, including stock of certain U.S. corporations owning significant U.S. real property, may be treated as ECI with respect to non-U.S. holders. In addition, certain income of non-U.S. holders from U.S. sources not connected to any such U.S. trade or business conducted by us could be treated as ECI. To the extent our income is treated as ECI, non-U.S. holders generally would be subject to withholding tax on their allocable shares of such income, would be required to file a U.S. federal income tax return for such year reporting their allocable shares of income effectively connected with such trade or business and any other income treated as ECI, and would be subject to U.S. federal income tax at regular U.S. tax rates on any such income (state and local income taxes and filings may also apply in that event). Non-U.S. holders that are corporations may also be subject to a 30% branch profits tax on their allocable share of such income. In addition, certain income from U.S. sources that is not ECI allocable to non-U.S. holders may be reduced by withholding taxes imposed at the highest effective applicable tax rate.

Tax-exempt entities face unique tax issues from owning common units that may result in adverse tax consequences to them.

In light of our investment activities, we will be treated as deriving income that constitutes “unrelated business taxable income,” or “UBTI.” Consequently, a holder of common units that is a tax-exempt organization may be subject to “unrelated business income tax” to the extent that its allocable share of our income consists of UBTI. A tax-exempt partner of a partnership could be treated as earning UBTI if the partnership regularly engages in a trade or business that is unrelated to the exempt function of the tax-exempt partner, if the partnership derives income from debt-financed property or if the partnership interest itself is debt-financed.

We cannot match transferors and transferees of common units, and we have therefore adopted certain income tax accounting positions that may not conform with all aspects of applicable tax requirements. The IRS may challenge this treatment, which could adversely affect the value of our common units.

Because we cannot match transferors and transferees of common units, we have adopted depreciation, amortization and other tax accounting positions that may not conform with all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to our common unitholders. It also could affect the timing of these tax benefits or the amount of gain on the sale of common units and could have a negative impact on the value of our common units or result in audits of and adjustments to our common unitholders’ tax returns.

The sale or exchange of 50% or more of our capital and profit interests will result in the termination of our partnership for U.S. federal income tax purposes. We will be considered to have been terminated for U.S. federal income tax purposes if there is a sale or exchange of 50% or more of the total interests in our capital and profits within a 12-month period. Our termination would, among other things, result in the closing of our taxable year for all common unitholders and could result in a deferral of depreciation deductions allowable in computing our taxable income.

Common unitholders will be subject to state and local taxes and return filing requirements as a result of investing in our common units.

In addition to U.S. federal income taxes, our common unitholders are subject to other taxes, including state and local taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we do business or own property now or in the future, even if our common

58

Table of Contents

unitholders do not reside in any of those jurisdictions. Our common unitholders are likely to be required to file state and local income tax returns and pay state and local income taxes in some or all of these jurisdictions. Further, common unitholders may be subject to penalties for failure to comply with those requirements. It is the responsibility of each common unitholder to file all U.S. federal, state and local tax returns that may be required of such common unitholder. Our counsel has not rendered an opinion on the state or local tax consequences of an investment in our common units.

We do not expect to be able to furnish to each unitholder specific tax information within 90 days after the close of each calendar year, which means that holders of common units who are U.S. taxpayers should anticipate the need to file annually a request for an extension of the due date of their income tax return. In addition, it is possible that common unitholders may be required to file amended income tax returns.

It will most likely require longer than 90 days after the end of our fiscal year to obtain the requisite information from all lower-tier entities so that K-1s may be prepared for the Partnership. For this reason, holders of common units who are U.S. taxpayers should anticipate the need to file annually with the IRS (and certain states) a request for an extension past April 15 or the otherwise applicable due date of their income tax return for the taxable year. In addition, it is possible that a common unitholder will be required to file amended income tax returns as a result of adjustments to items on the corresponding income tax returns of the partnership. Any obligation for a unitholder to file amended income tax returns for that or any other reason, including any costs incurred in the preparation or filing of such returns, are the responsibility of each common unitholder.
