RISK FACTORS

We are subject to a number of significant risks inherent in our business. You should carefully consider the risks and uncertainties described in our Annual Report, including those set forth under “Risk Factors” in our Annual Report. The risks discussed under the caption “Risk Factors” in our Annual Report that reference our Class A units and our organization and structure are generally applicable to the Series B Preferred units unless otherwise addressed herein. In addition, you should carefully consider the risks and uncertainties described below and the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. If any of these risks were to occur, our business and financial results could be seriously harmed. The trading price of our Series B Preferred units could decline as a result of any of these risks, and you could lose all or part of your investment.

Risks Relating to the Series B Preferred units

The Series B Preferred units are equity securities and are subordinated to our existing and future indebtedness.

The Series B Preferred units are our equity interests and do not constitute indebtedness. This means that the Series B Preferred units will rank junior to all of our indebtedness and to other non-equity claims on us and our assets available to satisfy claims on us, including claims in our liquidation.

Further, the Series B Preferred units place no restrictions on our business or operations or on our ability to incur indebtedness or engage in any transactions, subject only to the limited voting rights referred to below under “Risk Factors—Holders of the Series B Preferred units will have limited voting rights.”

We conduct substantially all of our operations through our subsidiaries, which hold the financial assets in which we invest. As a result, our cash flow and our ability to pay distributions on the Series B Preferred units are dependent upon the earnings of our subsidiaries. In addition, we are dependent on the distribution of earnings, loans or other payments by our subsidiaries to us.

Distributions on the Series B Preferred units are discretionary and non-cumulative.

Distributions on the Series B Preferred units are discretionary and non-cumulative. You will only receive distributions of the Series B Preferred units when, as and if declared by our board of directors. Consequently, if our board of directors does not authorize and declare a distribution for a distribution period, holders of the Series B Preferred units would not be entitled to receive any distribution for such distribution period, and such unpaid distribution will not be payable in such distribution period or in later distribution periods. We will have no obligation to pay distributions for a distribution period if our board of directors does not declare such distribution before the scheduled record date for such period, whether or not distributions are declared or paid for any subsequent distribution period with respect to the Series B Preferred units, our Series A Preferred units or any other preferred units we may issue. This may result in holders of the Series B Preferred units not receiving the full amount of distributions that they expect to receive, or any distributions, and may make it more difficult to resell Series B Preferred units or to do so at a price that the holder finds attractive.

Our board of directors may, in its sole discretion, determine to suspend distributions on the Series B Preferred units, which may have a material adverse effect on the market price of the Series B Preferred units. There can be no assurances that our operations will generate sufficient cash flows to enable us to pay distributions on the Series B Preferred units. Our financial and operating performance is subject to prevailing economic and industry conditions and to financial, business and other factors, some of which are beyond our control.

S-18

We may continue to make Permitted Distributions when distributions on the Series B Preferred units are suspended.

If our board of directors determines, in its sole discretion, to suspend distributions on the Series B Preferred units, we may still make Permitted Distributions (as defined under “Description of the Series B Preferred Units—Distributions”), which include, but are not limited to, tax distributions to the holders of our Class A units and to OCGH unitholders, distributions of incentive compensation and distributions to our subsidiaries or OCGH to pay expenses or other obligations. The holders of the Series B Preferred units will have no right to prohibit, and no claim over, any such distributions, which may be material in amount. See “Description of the Series B Preferred Units—Distributions.”

The terms of our future indebtedness may restrict our ability to make distributions on the Series B Preferred units or to redeem the Series B Preferred units.

Distributions will only be paid if the distribution is not restricted or prohibited by law or the terms of any senior equity securities or indebtedness. The instruments governing the terms of future financing or the refinancing of any borrowings may contain covenants that restrict our ability to make distributions on the Series B Preferred units or redeem the Series B Preferred units. The Series B Preferred units place no restrictions on our ability to incur indebtedness with such restrictive covenants.

The market price of the Series B Preferred units could be adversely affected by various factors.

Following the offering, the market price for the Series B Preferred units may fluctuate based on a number of factors, including:

Our performance, market conditions and prevailing interest rates have fluctuated in the past and can be expected to fluctuate in the future. Fluctuations in these factors could have an adverse effect on the price and liquidity of the Series B Preferred units. In general, as market interest rates rise, securities with fixed interest rates or fixed distribution rates, such as the Series B Preferred units, decline in value. Consequently, if you purchase the Series B Preferred units and market interest rates increase, the market price of the Series B Preferred units may decline. We cannot predict the future level of market interest rates.

Our ability to pay quarterly distributions on the Series B Preferred units will be subject to, among other things, our working capital levels, known or anticipated cash needs, business and investment opportunities, general economic and business conditions, our obligations under our debt instruments or other agreements, our

S-19

compliance with applicable laws, our financial results, the amount of ordinary taxable income or loss earned by us, gains or losses recognized by us on the disposition of assets and other liquidity needs. Any reduction or discontinuation of quarterly distributions could cause the market price of the Series B Preferred units to decline significantly. Accordingly, the Series B Preferred units may trade at a discount to their purchase price.

The Series B Preferred units may not be rated and, if rated, their ratings could be lowered.

We expect that Fitch Ratings Inc. and Standard & Poor’s Ratings Services will assign ratings to the Series B Preferred units. Generally, rating agencies base their ratings on such material and information, and such of their own investigative studies and assumptions, as they deem appropriate. A rating is not a recommendation to buy, sell or hold the Series B Preferred units, and there is no assurance that any rating will apply for any given period of time or that a rating may not be adjusted or withdrawn. A downgrade or potential downgrade in these ratings, the assignment of a new rating that is lower than existing ratings, or a downgrade or potential downgrade in ratings assigned to us, our subsidiaries, the Series B Preferred units, our Series A Preferred units or any of our other securities could adversely affect the trading price and liquidity of the Series B Preferred units. We cannot be sure that rating agencies will rate the Series B Preferred units or maintain their ratings once issued. Neither we nor any underwriter undertakes any obligation to obtain a rating, maintain the ratings once issued or advise holders of Series B Preferred units of any change in ratings. A failure to obtain a rating or a negative change in our ratings once issued could have an adverse effect on the market price or liquidity of the Series B Preferred units.

Rating agencies may change rating methodologies, and their ratings may not reflect all risks.

The rating agencies that currently or may in the future publish a rating for us or the Series B Preferred units may from time to time in the future change the methodologies that they use for analyzing securities with features similar to the Series B Preferred units. This may include, for example, changes to the relationship between ratings assigned to an issuer’s senior securities and ratings assigned to securities with features similar to the Series B Preferred units, which is sometimes called “notching.” If the rating agencies change their practices for rating lower-ranking securities in the future, and the ratings of the Series B Preferred units are subsequently lowered or “notched” further, the trading price and liquidity of the Series B Preferred units could be adversely affected. In addition, credit ratings may not reflect the potential impact of all structural risks, market risks, the additional factors discussed above and incorporated by reference herein and other factors that may affect the value of the Series B Preferred units. A credit rating is not a recommendation to buy, sell or hold securities and may be revised or withdrawn by the rating agency at any time. In addition, we may redeem the Series B Preferred units after the occurrence of a Rating Agency Event (as defined and described in “Description of the Series B Preferred Units—Rating Agency Redemption”). See the risk factor titled “Redemption may adversely affect your return on the Series B Preferred units” below.

An active trading market may not develop for the Series B Preferred units, which could adversely affect the price of the Series B Preferred units in the secondary market and your ability to resell the Series B Preferred units.

Because the Series B Preferred units do not have a stated maturity date, investors seeking liquidity will need to rely on the secondary market. The Series B Preferred units are a new issue of securities and there is no established trading market for the Series B Preferred units. We intend to apply for listing of the Series B Preferred units on the NYSE under the symbol “OAK PR B”. However, there is no guarantee that we will be able to list the Series B Preferred units. If the application is approved, we expect trading in the Series B Preferred units on the NYSE to begin within 30 days after the Series B Preferred units are first issued; however, we cannot make any assurance as to:

S-20

If a trading market were to develop, the future trading prices of the Series B Preferred units will depend on many factors, including those discussed above in the risk factor titled “The market price of the Series B Preferred units could be adversely affected by various factors.”

If a trading market does develop, there is no assurance that it will continue. If an active public trading market for the Series B Preferred units does not develop or does not continue, the market price and liquidity of the Series B Preferred units is likely to be adversely affected and Series B Preferred units traded after their purchase may trade at a discount from their purchase price.

Holders of the Series B Preferred units will have limited voting rights.

Holders of the Series B Preferred units will generally have no voting rights and have none of the voting rights given to holders of our Class A units, except that holders of the Series B Preferred units will be entitled to the voting rights described in “Description of the Series B Preferred Units—Voting Rights.” In particular, if distributions on the Series B Preferred units, or our Series A Preferred units or any other series of parity units (as defined in “Description of the Series B Preferred Units—Ranking”), have not been declared and paid for the equivalent of six or more quarterly distribution periods, whether or not consecutive (each, a “Nonpayment”), holders of the Series B Preferred units, together as a class with holders of any other series of parity units then outstanding with like voting rights, will be entitled to vote for the election of two additional directors to our board of directors, subject to the terms and to the limited extent described under “Description of the Series B Preferred Units—Voting Rights.” When quarterly distributions have been declared and paid on the Series B Preferred units, our Series A Preferred units and any other applicable series of parity units for four consecutive quarters following any Nonpayment, the right of the holders of the Series B Preferred units, our Series A Preferred units and such other parity units to elect these two additional directors will cease, the terms of office of these two directors will forthwith terminate and the number of directors constituting our board of directors will be reduced accordingly and, for purposes of determining whether a subsequent Nonpayment has occurred, the number of quarterly distributions payable on the Series B Preferred units that have not been declared and paid shall reset to zero.

In addition, if at any time any person or group (other than our manager and its affiliates, or a direct or subsequently approved transferee of our manager or its affiliates) acquires, in the aggregate, beneficial ownership of 20% or more of the Series B Preferred units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when calculating required votes or for other similar purposes.

Redemption may adversely affect your return on the Series B Preferred units.

On or after September 15, 2023, we will have the right to redeem at a price of $25.00 per Series B Preferred unit, plus declared and unpaid distributions, some or all of the Series B Preferred units, as described under “Description of the Series B Preferred Units—Optional Redemption.” In addition, prior to September 15, 2023, we may redeem the Series B Preferred units after the occurrence of a Change of Control Event (as defined and described in “Description of the Series B Preferred Units—Change of Control Redemption”) at a price of $25.25 per Series B Preferred unit, plus declared and unpaid distributions. Similarly, prior to September 15, 2023, we may redeem the Series B Preferred units after the occurrence of a Tax Redemption Event (as defined and described in “Description of the Series B Preferred Units—Tax Redemption”) or a Rating Agency Event (as defined and described in “Description of the Series B Preferred Units—Rating Agency Redemption”), in each case, at a price of $25.50 per Series B Preferred unit, plus declared and unpaid distributions. To the extent that we redeem the Series B Preferred units at times when prevailing interest rates may be relatively low compared to

S-21

rates at the time of issuance of the Series B Preferred units, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the distribution rate of the Series B Preferred units.

We are not required to redeem the Series B Preferred units when they become redeemable, and we only expect to do so if it is in our best interest as determined by our board of directors in its sole discretion.

The Series B Preferred units are a perpetual equity security. This means that they have no maturity or mandatory redemption date and are not redeemable at the option of investors. The Series B Preferred units may be redeemed by us at our option on or after September 15, 2023, either in whole or in part. In addition, prior to September 15, 2023, after the occurrence of a Change of Control Event, a Tax Redemption Event or a Rating Agency Event, we may, but are not required to, redeem the Series B Preferred units in whole but not in part. Any decision we may make at any time to redeem the Series B Preferred units will be determined by our board of directors in its sole discretion and depend upon, among other things, an evaluation of our capital position, the composition of our unitholders’ equity, our outstanding senior debt and general market conditions at that time.

We are not required to redeem the Series B Preferred units at any time, including upon a Change of Control Event. We may not be able to redeem the Series B Preferred units upon a Change of Control Event or pay the increased distribution rate per annum that applies when the Series B Preferred units remain outstanding subsequent to a Change of Control Event.

As of June 30, 2018, there was $600.0 million in aggregate principal amount of outstanding senior notes issued or guaranteed by certain of our subsidiaries, the holders of which may have the right to require us to repurchase all or any part of such holders’ securities upon a Change of Control. In addition, as of June 30, 2018, certain of our subsidiaries had $150.0 million in aggregate principal amount of term loans outstanding and availability to borrow up to $500.0 million in aggregate principal amount under our senior revolving credit facility, all of which may be required to be repaid upon a Change of Control. We are not required to redeem the Series B Preferred units at any time, and even if we should decide to redeem the Series B Preferred units, since the Series B Preferred units will rank junior to all of our existing and future indebtedness, upon a Change of Control Event, we may not have sufficient financial resources available to redeem the Series B Preferred units, or pay the increased distribution rate per annum described under “Description of the Series B Preferred Units—Change of Control Redemption.” Even if we are able to pay the increased distribution rate per annum, increasing the per annum distribution rate by 5.00% may not be sufficient to compensate holders for the impact of the Change of Control Event on the market price of the Series B Preferred units.

There is no limitation on our issuance of debt securities that rank senior to the Series B Preferred units or equity securities that rank equally with the Series B Preferred units and, under certain circumstances, we may issue equity securities that rank senior to the Series B Preferred units.

The terms of the Series A Preferred units do not, and the terms of the Series B Preferred units will not, limit our ability to incur indebtedness or other liabilities. As a result, we and our subsidiaries may incur indebtedness or other liabilities that will rank senior to the Series A Preferred units and the Series B Preferred units. In addition, we may issue additional equity securities that rank equally with the Series A Preferred units and the Series B Preferred units and, although we do not currently have any outstanding equity securities that rank senior to the Series A Preferred units and the Series B Preferred units, we may, with the approval of the holders of the Series B Preferred units and all other series of voting preferred units (as defined under “Description of the Series B Preferred Units—Voting Rights”) including the Series A Preferred units, acting as a single class, as described under “Description of the Series B Preferred Units—Voting Rights”, issue limited liability company interests senior to the Series B Preferred units. The incurrence of indebtedness or other liabilities that will rank senior to the Series B Preferred units and the issuance of securities ranking equally with or senior to the Series B Preferred units may reduce the amount available for distributions and the amount recoverable by holders of the Series B Preferred units in the event of our liquidation, dissolution or winding-up.

S-22

The terms of the Mirror Interests issued to us (or a wholly-owned subsidiary of ours) by Oaktree Capital I, L.P. in connection with this offering may be amended by Oaktree Capital I, L.P., which we control, in a manner that could be detrimental to you, and the Mirror Interests should not be relied upon to ensure we have sufficient cash flows to pay distributions on or redeem the Series B Preferred units.

We intend to cause the net proceeds from the sale of the Series B Preferred units to be contributed to Oaktree Capital I, L.P. In consideration of such contribution, Oaktree Capital I, L.P. will issue to us (or a wholly-owned subsidiary of ours) a new series of preferred interests with economic terms designed to materially mirror those of the Series B Preferred units, which we refer to as the Mirror Interests. The terms of the Mirror Interests will provide that unless distributions have been declared and paid or declared and set apart for payment on either (i) all Mirror Interests issued by Oaktree Capital I, L.P. for the then-current quarterly distribution period or (ii) the Series B Preferred units, then during such quarterly distribution period only, Oaktree Capital I, L.P. may not repurchase any of its junior interests and may not declare or pay or set apart payment for distributions on its junior interests, other than Oaktree I Permitted Distributions (as defined under “Description of the Series B Preferred Units—Mirror Interests”). These terms, among others, are intended to provide credit support to the Series B Preferred units. However, Oaktree Capital I, L.P. will have no direct obligations with respect to our Series B Preferred units. In addition, Oaktree Capital I, L.P.’s general partner, which is controlled by us, may amend, modify or alter the terms of the Mirror Interests, including the repurchase and distribution terms described above, in a manner that would be detrimental to the holders of the Series B Preferred units and such actions could materially and adversely affect the market price of the Series B Preferred units. Accordingly, the Mirror Interests should not be relied upon to ensure we have sufficient cash flows to enable us to pay distributions on or redeem the Series B Preferred units.

If the amount of distributions on the Series A Preferred units and the Series B Preferred units is greater than our gross ordinary income, then the amount that a holder of Series B Preferred units would receive upon liquidation may be less than the Preferred Unit Liquidation Value.

In general, to the extent of our gross ordinary income in any taxable year, we will specially allocate to the Series A Preferred units and the Series B Preferred units items of our gross ordinary income in an amount equal to the distributions paid in respect of the Series A Preferred units and the Series B Preferred units during the taxable year. Similar allocations will be made with respect to any equity securities we issue in the future that rank equally with the Series B Preferred units. Allocations of gross ordinary income will increase the capital account balances of the holders of the Series B Preferred units. Distributions will correspondingly reduce the capital account balances of the holders of the Series B Preferred units. So long as our gross ordinary income equals or exceeds the distributions paid to the holders of the Series A Preferred units and the Series B Preferred units, the capital account balances of the holders of Series B Preferred units with respect to the Series B Preferred units will equal the aggregate Preferred Unit Liquidation Value at the end of each taxable year. If the distributions paid in respect of the Series A Preferred units and the Series B Preferred units in a taxable year exceed our gross ordinary income, items of our gross ordinary income will be allocated to the Series A Preferred units and the Series B Preferred units pro rata based on the amount of distributions paid in respect of the Series A Preferred units and the Series B Preferred units, respectively, in such taxable year. If the distributions paid in respect of the Series B Preferred units in a taxable year exceed the proportionate share of our gross ordinary income allocated in respect of the Series B Preferred units for such year, the capital account balances of the holders of the Series B Preferred units with respect to the Series B Preferred units will be reduced below the aggregate Preferred Unit Liquidation Value by the amount of such excess. In that event, we will allocate additional gross ordinary income, to the extent available in any taxable year, in subsequent years until such excess is eliminated. If we were to have insufficient gross ordinary income to eliminate such excess, holders of Series B Preferred units would be entitled, upon our liquidation, dissolution or winding up, to less than the aggregate Preferred Unit Liquidation Value. In addition, to the extent that we make additional allocations of gross ordinary income in a taxable year to eliminate such excess from prior years, the gross ordinary income allocated to holders of the Series B Preferred units in such taxable year would exceed the distributions paid to the Series B Preferred units during such taxable year. In such taxable year, holders of Series B Preferred units may recognize taxable income in respect of their investments in the Series B Preferred units in excess of our cash

distributions, thus giving rise to an out-of-pocket tax liability for such holders. Future issuances of equity securities that rank equally with the Series B Preferred units could increase the likelihood that the capital account balances of holders of the Series B Preferred units decrease below the aggregate Preferred Unit Liquidation Value and holders of Series B Preferred units bear an out-of-pocket tax liability in future taxable years.

Holders of Series B Preferred 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 holders of Series B Preferred units may be required to file amended income tax returns.

Holders of Series B Preferred units will be required to take into account items of gross ordinary income that are allocated to them for our taxable year ending within or with their taxable year. It may require a substantial period of time after the end of our fiscal year to obtain the requisite information from all lower-tier entities so that tax information (including IRS Schedules K-1) may be prepared by us. For this reason, holders of Series B Preferred 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 the applicable due date of their income tax return for the taxable year. Because holders of our Series B Preferred units will be required to report the items of gross income that are allocated to them, tax reporting for such holders will generally be more complicated than for shareholders of a corporation.

In addition, it is possible that a holder of Series B Preferred units will be required to file amended income tax returns as a result of adjustments to items on the corresponding income tax returns of the Company. Any obligation for a holder of Series B Preferred units to file amended income tax returns for that or any other reason, including any costs incurred in the preparation or filing of such returns, is the responsibility of each holder of Series B Preferred units.

An investment in Series B Preferred units will give rise to UBTI to certain tax-exempt holders.

We will make investments through entities classified as partnerships or disregarded entities for U.S. federal income tax purposes in “debt-financed” property and, thus, an investment in Series B Preferred units will give rise to unrelated business taxable income (“UBTI”) to tax-exempt holders of Series B Preferred units. Moreover, if the IRS successfully asserts that we are engaged in a trade or business, then additional amounts of income could be treated as UBTI. Tax-exempt holders of our Series B Preferred units are strongly urged to consult their tax advisors regarding the tax consequences of owning our Series B Preferred units.

Because we are under no obligation to minimize UBTI, tax-exempt U.S. holders of Series B Preferred units should consult their own tax advisers regarding all aspects of UBTI.

Non-U.S. holders face unique U.S. tax issues from owning Series B Preferred units that may result in adverse tax consequences to them.

In light of our investment activities, we may be, or may become, engaged in a U.S. trade or business for U.S. federal income tax purposes, in which case some portion of our income would be treated as effectively connected income, or “ECI,” with respect to non-U.S. holders of our Series B Preferred units. Moreover, dividends paid by real estate investment trust, or “REIT,” investments that are attributable to gains from the sale of U.S. real property interests may be treated as ECI with respect to non-U.S. holders of our Series B Preferred units. In addition, certain income of non-U.S. holders from U.S. sources not connected to any U.S. trade or business conducted by us could be treated as ECI. We expect that we will earn ECI and/or income treated as ECI. To the extent our income is treated as ECI, each non-U.S. holder generally would be subject to withholding tax on distributions attributable to such income, would be required to file a U.S. federal income tax return for such year reporting such 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

S-24

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 (potentially reduced under an applicable tax treaty) on their allocable share of such income. In addition, if we are treated as being engaged in a U.S. trade or business, a portion of any gain recognized by non-U.S. holders on the sale or exchange of Series B Preferred units may be treated for U.S. federal income tax purposes as ECI. Consequently, such non-U.S. holders could be subject to U.S. federal income tax and branch profits tax on the sale or exchange of Series B Preferred units. In certain circumstances, the transferee of such Series B Preferred units may be required to deduct and withhold a tax equal to 10% of the amount realized (or deemed realized) on the sale or exchange such Series B Preferred units. The IRS recently released a notice suspending the withholding requirements described above for shares of publicly traded partnerships, such as us, until such time as regulations or other guidance have been issued. As a result, it is unclear how this provision may impact transfers of Series B Preferred units in the future. In addition, certain income from U.S. sources that is not ECI allocable to non-U.S. holders may be subject to withholding taxes imposed at the highest effective applicable tax rate. Non-U.S. holders of our Series B Preferred units are strongly urged to consult their tax advisors regarding the tax consequences of owning our Series B Preferred units.

Holders of Series B Preferred units may be subject to state and local taxes and return filing requirements as a result of investing in our Series B Preferred units.

In addition to U.S. federal income taxes, holders of our Series B Preferred units may be 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 the holders of our Series B Preferred units do not reside in any of those jurisdictions. Holders of our Series B Preferred units may also 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, holders of our Series B Preferred units may be subject to penalties for failure to comply with those requirements. It is the responsibility of each unitholder to file all U.S. federal, state and local tax returns that may be required of such unitholder.

Amounts distributed in respect of the Series B Preferred units could be treated as “guaranteed payments” for U.S. federal income tax purposes.

The treatment of interests in a partnership such as the Series B Preferred units and the payments received in respect of such interests is uncertain. The IRS may contend that payments on the Series B Preferred units represent “guaranteed payments,” which would generally be treated as ordinary income and may not have the same character when received by a holder as our gross ordinary income had when earned by us. If distributions on the Series B Preferred units are treated as “guaranteed payments,” a holder’s taxable income would be equal to the guaranteed payment accrued or received, regardless of the amount of our gross ordinary income. Our limited liability company agreement provides that we and all holders agree to treat payments made in respect of the Series B Preferred units as other than guaranteed payments. Potential holders of Series B Preferred units are encouraged to consult their own tax advisors regarding the treatment of payments on the Series B Preferred units as “guaranteed payments.”

Holders of Series B Preferred units who do not hold the units through the record date for a distribution may be allocated gross ordinary income even though no distribution is received.

While distributions (if any) with respect to Series B Preferred units will be made on a quarterly basis, under the allocation methodology we have adopted, we will prorate the total amount of gross ordinary income allocated to Series B Preferred units for a taxable year among holders of the Series B Preferred units on a monthly basis. As a result, a holder of a Series B Preferred unit who does not hold the Series B Preferred unit through the record date for a distribution may be allocated gross ordinary income even though no distribution is received. Holders of Series B Preferred units will remain liable for any income taxes associated with allocations of gross ordinary income even if they do not receive a distribution with respect to their Series B Preferred units or if the amount of such allocations exceed the amount of distributions they receive with respect to their Series B Preferred units. Any such gross ordinary income allocation will increase the holder’s adjusted basis in its Series B Preferred units.

USE OF PROCEEDS

We estimate that our proceeds from this offering net of underwriting commissions and discounts will be approximately $                million (or $                million assuming exercise in full of the over-allotment option).

We intend to use such net proceeds (including any such net proceeds resulting from the exercise of the over-allotment option) for general corporate purposes, including to fund investments. Pending specific application of these proceeds, we expect to invest them primarily in short-term demand deposits at various financial institutions. In addition, we will pay other expenses related to the offering out of cash on hand, which we estimate will total approximately $1 million.

RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED EQUITY DISTRIBUTIONS

The following table sets forth the historical ratio of earnings to fixed charges and preferred equity distributions for us and our consolidated subsidiaries for the periods indicated.

For purposes of computing the ratios of earnings to combined fixed charges and preferred equity distributions, earnings consist of pre-tax income from continuing operations before equity in (earnings) loss from non-controlling interests plus fixed charges, amortization of capitalized interest and distributions from equity investees. Fixed charges consist of interest expense, amortization of debt costs and an estimate of interest within net rental expense. We did not have any preferred equity outstanding for the years ended December 31, 2017, 2016, 2015, 2014 and 2013, and therefore the ratios of earnings to combined fixed charges and preferred equity distributions would be the same as the ratios of earnings to fixed charges presented above. On May 17, 2018, we issued 7,200,000 Series A Preferred units. Distributions on the Series A Preferred units will be payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning September 15, 2018, when, as and if declared by our board of directors out of funds legally available, at a rate per annum equal to 6.625% of the $25.00 liquidation preference per Series A Preferred unit. Assuming a distribution on the Series A Preferred units was declared and paid on June 15, 2018, the ratio of earnings to combined fixed charges and preferred equity distributions for the six months ended June 30, 2018 would be 2.47x.

DESCRIPTION OF THE SERIES B PREFERRED UNITS

The following description of the particular terms of the Series B Preferred units supplements the description of the general terms and provisions of preferred units and our operating agreement in the accompanying prospectus. The following description is a summary and it does not describe every aspect of the Series B Preferred Units. The following summary is subject to, and qualified in its entirety by reference to, all of the provisions of our operating agreement, a copy of which has been or will be incorporated by reference herein and which you may obtain as described under “Where You Can Find More Information and Incorporation by Reference,” and the Delaware Limited Liability Company Act. Therefore, you should read carefully the detailed provisions of the operating agreement. As used in this section, “the Company,” “we,” “us” and “our” mean Oaktree Capital Group, LLC, a Delaware limited liability company, and its successors, but not any of its subsidiaries or affiliates. Capitalized terms used but not otherwise defined herein have the meanings assigned to them in such operating agreement, and those definitions are incorporated herein by reference.

The Series B Preferred units are a single series of authorized preferred units, consisting of                units (or                units if the underwriters exercise their over-allotment option in full), all of which are being initially offered hereby. Our operating agreement permits our board of directors to authorize the issuance of an unlimited number of preferred units, in one or more classes or series without action by holders of outstanding Class A Units, Class B Units or preferred units. As of the date of this prospectus supplement, we have no outstanding Series B Preferred units and we have 7,200,000 outstanding Series A Preferred units that rank equally with the Series B Preferred units. We may from time to time, without notice to or the consent of holders of the Series B Preferred units, issue additional equity securities that rank equally with or junior to the Series B Preferred units. We may also from time to time, without notice to or consent of holders of the Series B Preferred units, issue additional Series B Preferred units. The additional Series B Preferred units would form a single series with the Series B Preferred units offered hereby.

Other than as provided in this section “Description of the Series B Preferred Units”, the Series B Preferred units are subject to the terms and provisions applicable to units generally under our operating agreement. See “Description of Units” in the accompanying prospectus. Each person who purchases or otherwise acquires Series B Preferred units will be admitted as a member of the Company and become bound by the terms of our operating agreement including a power of attorney as provided therein; see “Description of Units—Agreement to be Bound by Our Operating Agreement; Power of Attorney” in the accompanying prospectus.

Distributions

Distributions on the Series B Preferred units will be payable when, as and if declared by our board of directors out of funds legally available, at a rate per annum equal to    % of the $25.00 liquidation preference per unit. The liquidation preference per unit for purposes of calculating distributions will not be adjusted for any changes to the capital account balance per unit as described below under “—Amount Payable in Liquidation.”

Distributions on the Series B Preferred units will be payable quarterly on March 15, June 15, September 15 and December 15 of each year (each, a “distribution payment date”), beginning December 15, 2018, when, as and if declared by our board of directors. If any of those dates is not a business day, then distributions will be payable on the next succeeding business day. A “distribution period” is the period from and including a distribution payment date to, but excluding, the next distribution payment date, except that the initial distribution period will commence on and include the original issue date of the Series B Preferred units and end on December 15, 2018. The amount of distributions payable for the initial distribution period (which is payable on December 15, 2018) and any period shorter than a full distribution period will be computed on the basis of a 360-day year consisting of twelve 30-day months. Declared distributions will be payable on the relevant distribution payment date to holders of record as they appear on our register at the close of business, New York City time, on March 1, June 1, September 1 and December 1, as the case may be, immediately preceding the

S-28

relevant distribution payment date (each, a “record date”). These record dates will apply regardless of whether a particular record date is a business day, provided that if the record date is not a business day, the declared distributions will be payable on the relevant distribution payment date to holders of record as they appear on our register at the close of business, New York City time on the business day immediately preceding such record date. A “business day” means any day that is not a Saturday, Sunday or other day on which banking institutions in New York City are authorized or required by law to close.

Distributions on the Series B Preferred units are non-cumulative. Accordingly, if our board of directors does not declare a distribution before the scheduled record date for any distribution period, we will not make a distribution in that distribution period, whether or not distributions on the Series B Preferred units are declared or paid for any future distribution period.

The Series B Preferred units will rank senior to our Class A units and Class B units and any other non-preferred units (collectively, our “common units”) with respect to the payment of distributions to the extent provided in our operating agreement. Unless distributions have been declared and paid or declared and set apart for payment on the Series B Preferred units for a quarterly distribution period, no distribution may be declared or paid or set apart for payment on our common units (or on any of our other equity securities that we may issue in the future ranking, as to the payment of distributions, junior to the Series B Preferred units (together with our common units, “junior units”)) for the remainder of that quarterly distribution period, and we and our subsidiaries may not directly or indirectly repurchase, redeem or otherwise acquire for consideration our common units (or any junior unit), other than (i) distributions of tax distribution amounts received from the Oaktree Operating Group in accordance with the terms of the limited partnership agreements of the members of the Oaktree Operating Group as in effect on the date the Series B Preferred units are first issued, (ii) the net share settlement of equity-based awards granted under our 2011 Equity Incentive Plan, as amended or restated (or any successor or similar plan) in order to satisfy associated tax obligations (iii) exchanges of common units of us and/or our subsidiaries in connection with the exchange of units of OCGH for our common units or units of our subsidiaries under the exchange agreement, (iv) purchases pursuant to put or call arrangements with current or former Senior Executives, employees or service partners entered into in good faith in connection with the provision of personal services, (v) distributions of incentive compensation to current or former Senior Executives, employees or service partners in respect of their “points” interests in our subsidiaries, (vi) distributions, directly or indirectly, to us, our subsidiaries or OCGH to enable us, our subsidiaries or OCGH to pay expenses or satisfy other obligations (other than obligations in respect of distributions or purchases of junior securities that would not otherwise be Permitted Distributions), (vii) redemptions of common units pursuant to provisions of our operating agreement as in effect on the date of the first issuance of the Series B Preferred units, (viii) purchases in connection with the settlement of a bona fide forward purchase or accelerated unit repurchase arrangement with a third party financial institution that is entered into before the start of the applicable distribution period, (ix) payments made on redemption or conversion of convertible notes or convertible preferred equity or the entry into or settlement of call options, bond hedges and/or warrants to hedge the Company’s exposure in connection with the issuance of the convertible notes or convertible preferred equity, (x) distributions paid in, or exchanges of junior units or OCGH units for, junior units or options, warrants or rights to subscribe for or purchase junior units or distributions or purchases paid, directly or indirectly, with proceeds from the substantially concurrent sale of junior units and (xi) distributions, directly or indirectly, to OCGH or its successor to enable it to (A) make distributions in respect of any outstanding OCGH equity value units, and (B) purchase any OCGH units into which the equity value units have been recapitalized pursuant to any put right exercised by the holder of such units (the items in (i) through (xi) above, each, a “Permitted Distribution”). However, for a subsequent distribution period, payments on and repurchases or redemptions of junior units can be made again as long as distributions have been declared and paid or declared and set apart for payment on the Series B Preferred units for that period (even if no distributions have been made in one or more prior periods).

As discussed above, the distribution calculated for the initial distribution period, which is from the original issue date to but excluding December 15, 2018, is payable on December 15, 2018. If, for example, a distribution payment for the initial distribution period is not paid on December 15, 2018, no distribution may be declared or

S-29

paid or set apart for payment on our common units (or any junior unit) for the quarterly distribution period from and including December 15, 2018 to, but excluding March 15, 2019, and we and our subsidiaries may not repurchase, redeem or otherwise acquire for consideration our common units (or any junior unit) for such period, other than pursuant to a Permitted Distribution. However, payments on and repurchases or redemptions of junior units can be made for the subsequent distribution period from March 15, 2019 to but excluding June 15, 2019 as long as distributions calculated for the period from December 15, 2018 to but excluding March 15, 2019 have been paid on the Series B Preferred units on March 15, 2019. These restrictions are not applicable during the initial distribution period, which is the period from the original issue date to but excluding December 15, 2018.

Our board of directors, or a duly authorized representative thereof, may, in its discretion, choose to pay distributions on the Series B Preferred units without the payment of any distributions on our junior units. No distributions may be declared or paid or set apart for payment on any Series B Preferred units if at the same time any arrears exist or default exists in the payment of distributions on any outstanding class or series of our senior units (as defined below), if any are issued.

When distributions are not paid (or duly provided for) on any distribution payment date (or, in the case of parity units (as defined under “—Ranking”) having distribution payment dates different from the distribution payment dates pertaining to the Series B Preferred units, on a distribution payment date falling within the related distribution period for the Series B Preferred units) in full upon the Series B Preferred units, the Series A Preferred units or any other parity units, all distributions declared upon the Series B Preferred units, the Series A Preferred units and all such other parity units payable on such distribution payment date (or, in the case of parity units having distribution payment dates different from the distribution payment dates pertaining to the Series B Preferred units, on a distribution payment date falling within the related distribution period for the Series B Preferred units) shall be declared pro rata so that the respective amounts of such distributions shall bear the same ratio to each other as all declared and unpaid distributions per unit on the Series B Preferred units and all unpaid distributions, including any accumulations, on all parity units payable on such distribution payment date (or in the case of parity units having distribution payment dates different from the distribution payment dates pertaining to the Series B Preferred units, on a distribution payment date falling within the related distribution period for the Series B Preferred units) bear to each other.

Ranking

The Series B Preferred units will rank senior to our junior units with respect to payment of distributions and distribution of our assets upon our liquidation, dissolution or winding up.

The Series B Preferred units will rank equally with the Series A Preferred units and any of our equity securities, including preferred units, that we may issue in the future, the terms of which provide that such securities will rank equally with the Series B Preferred units with respect to payment of distributions and distribution of our assets upon our liquidation, dissolution or winding up (the Series A Preferred units and such other equity securities, “parity units”).

The Series B Preferred units will rank junior to (i) all of our existing and future indebtedness and (ii) any of our equity securities, including preferred units, that we may issue in the future, the terms of which provide that such securities will rank senior to the Series B Preferred units with respect to payment of unit distributions and distribution of our assets upon our liquidation, dissolution or winding up (such equity securities, “senior units”). We currently have no senior units outstanding. While any Series B Preferred units are outstanding, we may not authorize or create any class or series of senior units without the approval of two-thirds of the votes entitled to be cast by the holders of outstanding Series B Preferred units and all other classes or series of voting preferred units (as defined under “—Voting Rights”), acting as a single class. See “—Voting Rights” below for a discussion of the voting rights applicable if we seek to create any class or series of senior units.

S-30

Maturity

The Series B Preferred units do not have a maturity date, and we are not required to redeem or repurchase the Series B Preferred units. Accordingly, the Series B Preferred units will remain outstanding indefinitely unless we decide to redeem or repurchase them.

Optional Redemption

We may not redeem the Series B Preferred units prior to September 15, 2023 except as provided below under “—Change of Control Redemption,” under “—Tax Redemption” or under “—Rating Agency Event.” At any time or from time to time on or after September 15, 2023 we may, at our option, out of funds legally available, redeem the Series B Preferred units, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at a price of $25.00 per Series B Preferred unit plus declared and unpaid distributions, if any, to, but excluding, the redemption date, without payment of any undeclared distributions. If we choose to redeem less than all of the Series B Preferred units, we will either determine the Series B Preferred units to be redeemed by lot or pro rata or otherwise in accordance with applicable procedures of the Depository Trust Company and in compliance with the requirements of the New York Stock Exchange. Once proper notice has been given and so long as funds legally available and sufficient to pay the redemption price for all of the Series B Preferred units called for redemption have been set aside for payment, from and after the redemption date, distributions on the Series B Preferred units called for redemption will cease to accrue and such Series B Preferred units called for redemption will no longer be deemed outstanding, and all rights of the holders thereof will cease other than the right to receive the redemption price, without interest. In addition, similar to the Class A units and the Series A Preferred units, the Series B Preferred units may be redeemed pursuant to the provision described in the accompanying prospectus under “Description of Units—Limited Call Right” in the event less than 10% of the then outstanding Series B Preferred units are held by persons other than our senior executives, their successors or entities directly or indirectly controlled by them, including OCGH, and may be redeemed or caused to be transferred at the current market price as defined in the operating agreement pursuant to the provisions described in the accompanying prospectus under “Description of Units—Transfer Restrictions” and “Description of Units—Non-Citizen Assignee; Redemption.”

Holders of the Series B Preferred units will have no right to require us or any of our subsidiaries to redeem any of the Series B Preferred units.

Change of Control Redemption

If a Change of Control Event (as defined below) occurs prior to September 15, 2023, we may, at our option, out of funds legally available, redeem the Series B Preferred units, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such Change of Control Event, at a price of $25.25 per Series B Preferred unit, plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. Notices of redemption may, at our sole discretion, be conditional, as described in “—Conditional Redemption.”

If (i) a Change of Control Event occurs (whether before, on or after September 15, 2023) and (ii) we do not give notice prior to the 31st day following the Change of Control Event to redeem all the outstanding Series B Preferred units, the distribution rate per annum on the Series B Preferred units will increase by 5.00%, beginning on the 31st day following such Change of Control Event.

“Below Investment Grade Rating Event” means (x) the rating on any series of the Oaktree Senior Notes (or, if no Oaktree Senior Notes are outstanding, or no Oaktree Senior Notes are then rated by the applicable Rating Agency, our long-term issuer rating by such Rating Agency) is lowered by either of the Rating Agencies in respect of a Change of Control and (y) any series of the Oaktree Senior Notes (or, if no Oaktree Senior Notes are outstanding or no Oaktree Senior Notes are then rated by the applicable Rating Agency, our long-term issuer

S-31

rating by such Rating Agency) is rated below Investment Grade by both Rating Agencies on any date from the date of the public notice by the Company of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended until the ratings are announced if during such 60-day period the rating of any series of the Oaktree Senior Notes (or, if no Oaktree Senior Notes are outstanding or no Oaktree Senior Notes are then rated by the applicable Rating Agency, our long-term issuer rating by such Rating Agency) is under publicly announced consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform us that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event). We will request the Rating Agencies to make such confirmation in connection with any Change of Control.

“Change of Control” means the occurrence of the following:

For the avoidance of doubt, the failure of the Oaktree control condition to be satisfied shall not, in and of itself, be deemed to be a “Change of Control.”

“Change of Control Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“CLO” means a collateralized loan obligation vehicle or similar debt securitization vehicle or entity.

“CLO Subsidiary” means, at any time, (i) any subsidiary that (x) manages or has been established to manage one or more CLOs or (y) is an affiliate of a subsidiary described in clause (x) that purchases or otherwise acquires and/or retains securities, obligations or other interests in such CLO for the purpose of, among other things, satisfying (including on a prospective basis) any applicable risk retention laws, rules, regulations, guidelines, technical standards or guidance of any governmental authority and (ii) any subsidiary of a subsidiary described in the preceding clause (i). For the avoidance of doubt, the assets and obligations of any CLO Subsidiary will not be deemed to include the assets and obligations of any CLO such CLO Subsidiary may manage, except to the extent of any ownership of securities or obligations issued by, or other interests in, such CLO held by the CLO Subsidiary.

“Continuing Oaktree Person” means, immediately prior to and immediately following any relevant date of determination, (a) an individual who is a Senior Executive, (b) an individual who is an executive or other

S-32

employee of Oaktree Capital Group, LLC and/or its subsidiaries who, as of any date of determination, has devoted substantially all of his or her business and professional time to the activities of Oaktree Capital Group, LLC or any of its subsidiaries during the 12 month period immediately preceding such date (each such person, an “Executive”), (c) Oaktree Capital Group Holdings GP, LLC, Oaktree Capital Group Holdings, L.P. or any other Person in which any one or more of such individuals directly or indirectly, singly or as a group, holds a majority of the Voting Units, (d) any Person that is a family member of such individual or individuals, (e) any trust, foundation or other estate planning vehicle for which such individual acts as a trustee or beneficiary (any Person referred to in clause (c), (d) or (e) is referred to as a “Related Party”) or (f) any trust described in the accompanying prospectus under “Description of Units—Grantor Trust”, or any other entity that acquires all of our outstanding Class A units in exchange for common equity interests in such entity immediately following which acquisition the former holders of Class A units and other Continuing Oaktree Persons collectively beneficially own directly or indirectly a majority of the controlling interests in the Company (any such trust or entity, an “Eligible Holding Entity”). Notwithstanding the foregoing, Oaktree Capital Group Holdings GP, LLC, Oaktree Capital Group Holdings, L.P., any Eligible Holding Entity, each of the Senior Executives and any Related Party of such Senior Executive and each of the Executives and any Related Party of such Executive shall be deemed to be a Continuing Oaktree Person.

“Fitch” means Fitch Ratings Inc. or any successor thereto.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch) and BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) (or, in each case, if such Rating Agency ceases to rate a series of the Oaktree Senior Notes (or, if no Oaktree Senior Notes are outstanding, ceases to assign a long-term issuer rating to us) for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Majority Economic Interest” means any right or entitlement to receive more than 50% of the equity distributions or partnership allocations (whether such right or entitlement results from the ownership of partner or other equity interests, securities, instruments or agreements of any kind) made to all holders of equity interests in the Oaktree Issuer Group (other than to entities within the Oaktree Issuer Group).

“Oaktree Issuer Group” means Oaktree Capital Group, LLC, the members of the Oaktree Operating Group and any other entity that, as of the relevant time, is a guarantor to any series of Oaktree Senior Notes, and their direct and indirect subsidiaries (to the extent of their economic ownership interest in such subsidiaries), taken as a whole.

“Oaktree Senior Notes” means (i) the 3.91% Senior Notes, Series A, due 2024 issued by Oaktree Capital Management, L.P., (ii) the 4.01% Senior Notes, Series B, due 2026 issued by Oaktree Capital Management, L.P., (iii) the 4.21% Senior Notes, Series C, due 2029 issued by Oaktree Capital Management, L.P., (iv) the 3.69% Senior Notes due 2031 issued by Oaktree Capital Management, L.P., (v) the 3.78% Senior Notes due 2032 issued by Oaktree Capital Management, L.P. and any similar series of senior unsecured debt securities, in each case, guaranteed by Oaktree Capital I, L.P., Oaktree Capital II, L.P. and Oaktree AIF Investments, L.P., each of which is a member of the Oaktree Operating Group.

“Rating Agency” means:

“Senior Executive” means, as the date the Series B Preferred units are first issued Howard S. Marks, Bruce A. Karsh, Jay S. Wintrob, John B. Frank and Sheldon M. Stone, and any other person who may from time to time, prior to the failure of the Oaktree control condition to be satisfied, be designated by the board of directors as a “principal” of the Company, in each case until his or her death, disability, resignation or removal by the board of directors.

“S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill Financial, Inc., or any successor thereto.

The Change of Control redemption feature of the Series B Preferred units may, in certain circumstances, make more difficult or discourage a sale or takeover of our limited liability company or a member of the Oaktree Operating Group and, thus, the removal of incumbent management. We have no present intention to engage in a transaction involving a Change of Control, although it is possible that we could decide to do so in the future.

Tax Redemption

If a Tax Redemption Event (as defined under “Description of the Series B Preferred units—Tax Redemption Event”) occurs prior to September 15, 2023, we may, at our option, out of funds legally available, redeem the Series B Preferred units, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such Tax Redemption Event, at a price of $25.50 per Series B Preferred unit, plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. Notices of redemption may, at our sole discretion, be conditional, as described in “—Conditional Redemption.”

“Tax Redemption Event” means, after the date the Series B Preferred units are first issued, (a) due to an amendment to, or a change in official interpretation of, the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, or administrative guidance or (b) due to an administrative or judicial determination (i) we are advised by nationally recognized counsel or a “Big Four” accounting firm that the Company will be treated as an association taxable as a corporation for U.S. federal income tax purposes or otherwise subject to U.S. federal income tax (other than any tax imposed pursuant to Section 6225 of the Code, as amended by the Bipartisan Budget Act of 2015), or (ii) the Company files an IRS Form 8832 (or successor form) electing that the Company be treated as an association taxable as a corporation for U.S. federal income tax purposes, the Company converts or merges into a corporation, or the Company is otherwise treated as an association taxable as a corporation for U.S. federal income tax purposes.

Rating Agency Redemption

If a Rating Agency Event (as defined herein) occurs prior to September 15, 2023, we may, at our option, out of funds legally available, redeem the Series B Preferred units, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such Rating Agency Event, at a price of $25.50 per Series B Preferred unit, plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. Notices of redemption may, at our sole discretion, be conditional, as described in “—Conditional Redemption.”

S-34

A “Rating Agency Event” means a change to the methodology or criteria that were employed by an applicable nationally recognized statistical rating organization for purposes of assigning equity credit to securities with features similar to the Series B Preferred units on the date of original issuance (the “current methodology”), which change either (x) shortens the period of time during which equity credit pertaining to Series B Preferred units would have been in effect had the current methodology not been changed or (y) reduces the amount of equity credit assigned to the Series B Preferred units as compared with the amount of equity credit that such rating agency had assigned to the Series B Preferred units as of the date of original issuance.

Conditional Redemption

Notice of any redemption that is to occur prior to September 15, 2023, whether in connection with a Change of Control Event, Tax Redemption Event or Rating Agency Event, may be given prior to the completion thereof, and any such redemption or notice may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related Change of Control Event, Tax Redemption Event or Rating Agency Event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed; provided, however, that the redemption date, if such redemption is conditional, shall not be delayed beyond September 15, 2023. In addition, we may provide in such notice that payment of the redemption price and performance of our obligations with respect to such redemption may be performed by another Person (as defined herein).

We and our affiliates may acquire the Series B Preferred units by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise.

Voting Rights

Except as indicated below in this section “Voting Rights,” the holders of the Series B Preferred units will have no voting or approval rights.

If and whenever six quarterly distributions (whether or not consecutive) payable on the Series B Preferred units have not been declared and paid (a “Nonpayment”), the number of directors then constituting our board of directors will be increased by two and the holders of the Series B Preferred units, voting together as a single class with the holders of any other series of parity units then outstanding upon which like voting rights have been conferred and are exercisable (any such other series, which for the avoidance of doubt includes the Series A Preferred units, the “voting preferred units”), will have the right to elect these two additional directors at a meeting of the holders of the Series B Preferred units and such other voting preferred units. When quarterly distributions have been declared and paid on the Series B Preferred units and any other applicable voting preferred units for four consecutive quarters following any Nonpayment, the right of the holders of the Series B Preferred units and any other voting preferred units to elect these two additional directors will cease, the terms of office of these two directors will forthwith terminate and the number of directors constituting our board of directors will be reduced accordingly and, for purposes of determining whether a Nonpayment has occurred, the number of quarterly distributions payable on the Series B Preferred units that have not been declared and paid shall reset to zero. However, the right of the holders of the Series B Preferred units and any other voting preferred units to elect two additional directors will again vest if and whenever a Nonpayment occurs.

The approval of two-thirds of the votes entitled to be cast by the holders of outstanding Series B Preferred units and all other series of voting preferred units, acting as a single class regardless of series, either at a meeting of unitholders or by written consent, is required in order:

S-35

provided that in the case of clause (i) above, if such amendment affects materially and adversely the rights, preferences, privileges or voting powers of one or more but not all of the classes or series of voting preferred units (including the Series B Preferred units for this purpose), only the consent of the holders of at least two-thirds (66-2/3%) of the outstanding units of the classes or series so affected, voting as a class, is required in lieu of (or, if such consent is required by law, in addition to) the consent of the holders of two-thirds (66-2/3%) of the voting preferred units (including the Series B Preferred units for this purpose) as a class.

However, we may create additional series or classes of parity units and junior units and issue additional classes or series of parity units and junior units without notice to or the consent of any holder of the Series B Preferred units.

The foregoing voting provisions will not apply with respect to the Series B Preferred units if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, the Series B Preferred units shall have been redeemed or proper notice of redemption of the Series B Preferred units has been given and funds sufficient to pay the redemption price for all of the Series B Preferred units have been set aside for payment pursuant to the terms of our operating agreement.

In addition, if at any time any person or group (other than our manager and its affiliates, or a direct or subsequently approved transferee of our manager or its affiliates) acquires, in the aggregate, beneficial ownership of 20% or more of the Series B Preferred units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when calculating required votes or for other similar purposes.

Amount Payable in Liquidation

Upon any voluntary or involuntary liquidation, dissolution or winding up of our limited liability company (“Liquidation”), each holder of the Series B Preferred units will be entitled to a payment out of our assets available for distribution to the holders of the Series B Preferred units following the satisfaction of all claims ranking senior to the Series B Preferred units. Such payment will equal the sum of the $25.00 liquidation preference per Series B Preferred unit and declared and unpaid distributions, if any, to, but excluding, the date of Liquidation (the “Preferred Unit Liquidation Value”), to the extent that we have sufficient gross income (excluding any gross income attributable to the sale or exchange of capital assets) in the year of Liquidation and in the prior years in which the Series B Preferred units have been outstanding to ensure that each holder of Series B Preferred units will have a capital account balance equal to the Preferred Unit Liquidation Value.

The capital account balance for each Series B Preferred unit will equal $25.00 initially and will be increased each year by an allocation of gross ordinary income recognized by us (including any gross ordinary income recognized in the year of Liquidation). We refer to our gross income (excluding any gross income attributable to the sale or exchange of capital assets) as our “gross ordinary income.” The allocations of gross ordinary income

S-36

to the capital account balances for the Series B Preferred units in any year will not exceed the sum of the amount of distributions paid on the Series B Preferred units during such year and, to the extent the amount of our distributions in prior years exceeded the cumulative gross ordinary income allocated to the capital account balances for the Series B Preferred units in those years, the amount of such excess for all prior years. If our board of directors declares a distribution on the Series B Preferred units, the amount of the distribution paid on each such Series B Preferred unit will be deducted from the capital account balance for such Series B Preferred unit, whether or not such capital account balance received an allocation of gross ordinary income in respect of such distribution. The allocation of gross ordinary income to the capital account balances for the Series B Preferred units is intended to entitle the holders of the Series B Preferred units to a preference over the holders of outstanding common units upon our Liquidation, to the extent required to permit each holder of a Series B Preferred unit to receive the Preferred Unit Liquidation Value in respect of such unit. If, however, we were to have insufficient gross ordinary income to achieve this result, holders of Series B Preferred units would be entitled, upon Liquidation, to less than the Preferred Unit Liquidation Value and may receive less than $25.00 per Series B Preferred unit. See “Risk Factors—If the amount of distributions on the Series A Preferred units and the Series B Preferred units is greater than our gross ordinary income, then the amount that a holder of Series B Preferred units would receive upon liquidation may be less than the Preferred Unit Liquidation Value.”

After each holder of Series B Preferred units receives a payment equal to the lesser of the Preferred Unit Liquidation Value and the capital account balance for such holder’s Series B Preferred units, holders will not be entitled to any further participation in any distribution of our assets.

Based on current information, we believe we will have sufficient gross ordinary income in calendar year 2018 to ensure that holders of Series B Preferred units will have capital account balances as of the end of calendar year 2018, that entitle each holder, upon Liquidation, to the Preferred Unit Liquidation Value, but no assurance can be provided regarding the level of our calendar year 2018 gross ordinary income or of our future gross ordinary income. In our 2017 and 2016 taxable years, our gross ordinary income was $79.9 million and $102.3 million respectively.

If upon any Liquidation, the amounts payable with respect to the Series B Preferred units and any other outstanding class or series of parity units, including the Series A Preferred units, are not paid in full, then the holders of the Series B Preferred units and the holders of such parity units, including the Series A Preferred units, will share equally and ratably in any distribution of our assets in proportion to the full distributable amounts to which each such holder is entitled. As of the date of this prospectus supplement, there are 7,200,000 Series A Preferred units outstanding.

None of the sale, conveyance, exchange or transfer, for cash, shares of capital stock, securities or other consideration, of all or substantially all of our property or assets nor the consolidation, merger or amalgamation of our limited liability company with or into any other entity or the consolidation, merger or amalgamation of any other entity with or into our limited liability company will be deemed to be a voluntary or involuntary liquidation, dissolution or winding up of our limited liability company, notwithstanding that for other purposes, such as for tax purposes, such an event may constitute a liquidation, dissolution or winding up. We refer to the foregoing transactions as “Permitted Transfers.” In addition, no payment will be made to the holders of the Series B Preferred units pursuant to this “—Amount Payable in Liquidation” section (i) upon the voluntary or involuntary liquidation, dissolution or winding up of any of our subsidiaries or upon any reorganization of our limited liability company into another limited liability entity pursuant to provisions of our operating agreement that allow us to convert, merge or convey our assets to another limited liability entity with or without approval of our members (including a merger or conversion of our limited liability company into a corporation if the board of directors determines in its sole discretion that it is no longer in the interests of our limited liability company to continue as a partnership for U.S. federal income tax purposes) or (ii) if our limited liability company engages in a reorganization or other transaction in which a successor to our limited liability company issues equity securities to the holders of the Series B Preferred units that have rights, powers and preferences that are substantially similar to the rights, powers and preferences of the Series B Preferred units pursuant to provisions of our

S-37

operating agreement that allow us to do so without approval of our members. We refer to the foregoing transactions as “Permitted Reorganizations.” The board of directors may, in its sole discretion, modify the terms of the Series B Preferred units to provide for a Permitted Transfer or a Permitted Reorganization.

No Conversion Rights

The Series B Preferred units will not be convertible into common units or any other class or series of interests or any other security at any time.

Mirror Interests

We intend to cause the net proceeds from the sale of the Series B Preferred units to be contributed to Oaktree Capital I, L.P. (“Oaktree I”), which is a member of the Oaktree Operating Group. In consideration of our contribution, Oaktree I will issue to us (or a wholly-owned subsidiary of ours) a new series of preferred interests with economic terms designed to materially mirror those of the Series B Preferred units, which we refer to as the Mirror Interests. The terms of the Mirror Interests will provide that unless distributions have been declared and paid or declared and set apart for payment on either (x) the Mirror Interests or (y) the Series B Preferred units, then during such quarterly distribution period only, Oaktree I may not repurchase its common units or any junior units and may not declare or pay or set apart payment for distributions on its junior units, other than the following, or repurchases or distributions the proceeds of which are used, directly or indirectly, to effect the following: (i) distributions of tax distribution amounts in accordance with the terms of the limited partnership agreement of Oaktree I as in effect on the date the Series B Preferred units are first issued, (ii) the net share settlement of equity-based awards granted under our 2011 Equity Incentive Plan, as amended or restated (or any successor or similar plan) in order to satisfy associated tax obligations (iii) exchanges of common units of us and/or our subsidiaries in connection with the exchange of units of OCGH for our common units or units of our subsidiaries under the exchange agreement, (iv) purchases pursuant to put or call arrangements with current or former Senior Executives, employees or service partners entered into in good faith in connection with the provision of personal services, (v) distributions of incentive compensation to current or former Senior Executives, employees or service partners in respect of their “points” interests in our subsidiaries, (vi) distributions, directly or indirectly, to us, our subsidiaries or OCGH to enable us, our subsidiaries or OCGH to pay expenses or satisfy other obligations (other than obligations in respect of distributions or purchases of junior securities that would not otherwise be Permitted Distributions), (vii) redemptions of common units pursuant to provisions of our operating agreement as in effect on the date of the first issuance of the Series B Preferred units, (viii) purchases in connection with the settlement of a bona fide forward purchase or accelerated unit repurchase arrangement with a third party financial institution that is entered into before the start of the applicable distribution period, (ix) payments made on redemption or conversion of convertible notes or convertible preferred equity or the entry into or settlement of call options, bond hedges and/or warrants to hedge the Company’s exposure in connection with the issuance of the convertible notes or convertible preferred equity, (x) distributions paid in, or exchanges of junior units or OCGH units for, junior units or options, warrants or rights to subscribe for or purchase junior units or distributions or purchases paid, directly or indirectly, with proceeds from the substantially concurrent sale of junior units and (xi) distributions, directly or indirectly, to OCGH or its successor to enable it to (A) make distributions in respect of any outstanding OCGH equity value units, and (B) purchase any OCGH units into which the equity value units have been recapitalized pursuant to any put right exercised by the holder of such units (the items in (i) through (xi) above, each, an “Oaktree I Permitted Distribution”). In connection with the issuance of the Series A Preferred units, Oaktree I issued an aggregate of 7,200,000 Series A Preferred Mirror Units, which are preferred units with economic terms designed to mirror those of the Series A Preferred units.

The terms of the Mirror Interests will also provide that Oaktree I may not liquidate, dissolve or wind-up unless the outstanding liquidation preference on all outstanding Mirror Interests has been repaid via redemption or otherwise. The foregoing would not apply to (i) a Substantially All Merger or a Substantially All Sale whereby a member of the Oaktree Operating Group is the surviving Person and has expressly assumed all of the

S-38

obligations under the Mirror Interests, (ii) the sale or disposition of Oaktree I (whether by merger, consolidation or the sale of all or substantially all of its assets) if such sale or disposition is not a Substantially All Merger or Substantially All Sale, (iii) the sale or disposition of Oaktree I if Oaktree I does not then constitute a “significant subsidiary” of ours under Rule 1-02(w) of Regulation S-X promulgated by the Securities and Exchange Commission, (iv) an event where the Series B Preferred units have been fully redeemed pursuant to terms of our operating agreement or if proper notice of redemption of the Series B Preferred units has been given and funds sufficient to pay the redemption price for all of the Series B Preferred units called for redemption have been set aside for payment pursuant to the terms of our operating agreement, (v) transactions where the assets of Oaktree I upon liquidation, dissolution or winding up are immediately contributed to another member of the Oaktree Operating Group that expressly assumes all of the obligations under the Mirror Interests and (vi) with respect to Oaktree I, a Permitted Transfer or a Permitted Reorganization.

“Person” means any individual, corporation, firm, partnership, joint venture, limited liability company, estate, trust, business association, organization, governmental entity or other entity.

“Substantially All Merger” means a merger or consolidation of Oaktree I with or into another Person that would, in one or a series of related transactions, result in the transfer or other disposition, directly or indirectly, of all or substantially all of the assets of Oaktree I to a Person that is not a member of the Oaktree Operating Group immediately prior to such transaction.

“Substantially All Sale” means a sale, assignment, transfer, lease or conveyance, in one or a series of related transactions, directly or indirectly, of all or substantially all of the assets of Oaktree I to a Person that is not a member of the Oaktree Operating Group immediately prior to such transaction.

Forum Selection

Each person that holds or has held a Series B Preferred unit and each person that holds or has held any beneficial interest in a Series B Preferred unit (whether through a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing or otherwise), to the fullest extent permitted by law, (i) irrevocably agrees that any claims, suits, actions or proceedings against us, or any director, officer, employee, control person, underwriter or agent of Oaktree Capital Group, LLC, asserted under United States federal securities laws, otherwise arising under such laws, or that could have been asserted as a claim arising under such laws, shall be exclusively brought in the federal district courts of the United States of America (except, and only to the extent, that any such claims, actions or proceedings are of a type for which a member may not waive its right to maintain a legal action or proceeding in the courts of the State of Delaware with respect to matters relating to the organization or internal affairs of Oaktree Capital Group, LLC as set forth under Section 18-109(d) of the Delaware Limited Liability Company Act); (ii) irrevocably submits to the exclusive jurisdiction of such courts in connection with any such claim, suit, action or proceeding; and (iii) irrevocably agrees not to, and waives any right to, assert in any such claim, suit, action or proceeding that (A) it is not personally subject to the jurisdiction of such courts or any other court to which proceedings in such courts may be appealed, (B) such claim, suit, action or proceeding is brought in an inconvenient forum, or (C) the venue of such claim, suit, action or proceeding is improper.

Transfer Agent, Registrar and Paying Agent

American Stock Transfer & Trust Company, LLC will be the transfer agent, registrar and paying agent for the Series B Preferred units.

S-39

BOOK-ENTRY, DELIVERY AND FORM

The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the Series B Preferred units. The Series B Preferred units will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC.

DTC has advised us that: DTC, the world’s largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s rating of AA+. The DTC Rules applicable to its Participants are on file with the SEC. More information about DTC can be found at www.dtcc.com.

Purchases of Series B Preferred units under the DTC system must be made by or through Direct Participants, which will receive a credit for the Series B Preferred units on DTC’s records. The ownership interest of each actual purchaser of each Series B Preferred unit (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Series B Preferred units are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Series B Preferred units, except in the event that use of the book-entry system for the Series B Preferred units is discontinued.

To facilitate subsequent transfers, all Series B Preferred units deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Series B Preferred units with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Series B Preferred units; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Series B Preferred units are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

S-40

Redemption notices shall be sent to DTC. If less than all of the Series B Preferred units within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Series B Preferred units unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Series B Preferred units are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Redemption proceeds and distributions on the Series B Preferred units will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or American Stock Transfer & Trust Company, LLC on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, its nominee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds and distributions to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is our responsibility, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

Except as provided herein, a Beneficial Owner of the Series B Preferred units will not be entitled to receive physical delivery of the Series B Preferred units. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the Series B Preferred units. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in the Series B Preferred units.

DTC may discontinue providing its services as depository with respect to the Series B Preferred units at any time by giving us reasonable notice. Under such circumstances, in the event that a successor depository is not obtained, share certificates are required to be printed and delivered.

We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, share certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS

This summary discusses the material U.S. federal income and estate tax considerations related to the purchase, ownership and disposition of our Series B Preferred units as of the date hereof. This summary is based on provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), on the regulations promulgated thereunder and on published administrative rulings and judicial decisions, all of which are subject to change at any time, possibly with retroactive effect. This discussion is limited to the material U.S. federal income and estate tax considerations related to the purchase, ownership and disposition of our Series B Preferred units and does not cover all U.S. federal income and estate tax considerations that may be applicable to a particular investor. In particular, some categories of investors, such as dealers in securities, financial institutions, regulated investment companies, real estate investment trusts, thrifts, insurance companies, persons holding our Series B Preferred units as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle, traders in securities that have elected the mark-to-market method of accounting for securities, persons subject to the alternative minimum tax, persons who own or are deemed to own 10% or more of our stock (by vote or value), persons required to accelerate the recognition of any item of gross income with respect to Series B Preferred units as a result of such income being recognized on an applicable financial statement, U.S. expatriates, persons with a functional currency other than the dollar, dealers, foreign pension funds, “controlled foreign corporations,” “passive foreign investment companies,” partnerships or other pass-through entities for U.S. federal income tax purposes, and other investors that do not own their Series B Preferred units as capital assets, may be subject to special rules not described herein. Such investors should consult with their tax advisors concerning the U.S. federal, state and local income tax and estate tax consequences in their particular situations of the purchase, ownership and disposition of a Series B Preferred unit. Tax-exempt organizations and mutual funds are discussed separately below. The actual tax consequences of the purchase and ownership of Series B Preferred units will vary depending on your circumstances. This discussion, to the extent it states matters of U.S. federal tax law or legal conclusions and subject to the qualifications herein, represents the opinion of Simpson Thacher & Bartlett LLP. Such opinion is based in part on facts described in this prospectus and on various other factual assumptions, representations and determinations, including representations contained in certificates provided to Simpson Thacher & Bartlett LLP. The failure of such facts, assumptions, representations or determinations to be true and accurate could adversely impact the accuracy of this summary and such opinion. Moreover, opinions of counsel are not binding on the Internal Revenue Service (“IRS”) or any court, and the IRS could challenge the conclusions herein, and a court could sustain such a challenge.

For purposes of this discussion, a “U.S. Holder” is a beneficial holder of a Series B Preferred unit that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States; (2) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or (4) a trust if it (a) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person. A “non-U.S. Holder” is a holder that is not a U.S. Holder.

If a partnership holds Series B Preferred units, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our Series B Preferred units, you should consult your tax advisers. This discussion does not constitute tax advice and is not intended to be a substitute for tax planning.

Prospective holders of Series B Preferred units should consult their own tax advisers concerning the U.S. federal, state and local income tax and estate tax consequences in their particular situations of the purchase, ownership and disposition of a Series B Preferred unit, as well as any consequences under the laws of any other taxing jurisdiction.

Taxation of Oaktree Capital Group, LLC

Subject to the discussion in the next two paragraphs, an entity that is treated as a partnership for U.S. federal income tax purposes is generally not a taxable entity for U.S. federal income tax purposes and incurs no U.S. federal income tax liabilities. Instead, each partner of a partnership is required to take into account its allocable share of items of income, gain, loss and deduction of the partnership in computing its U.S. federal income tax liability, regardless of whether cash distributions are made. Distributions of cash by a partnership to a partner are not taxable unless the amount of cash distributed to a partner is in excess of the partner’s adjusted basis in its partnership interest.

Legislation that became effective for taxable years beginning after December 31, 2017 may impose liability for adjustments to a partnership’s tax returns on the partnership itself in certain circumstances absent an election to the contrary. The effects of the application of this legislation on us are uncertain, and prospective investors should consult their own tax advisors regarding all aspects of this legislation as it affects their particular circumstances. See discussion below under “Administrative Matters—Partnership Audit Legislation.”

An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes may nonetheless be taxable as a corporation if it is a “publicly traded partnership,” unless an exception applies. An entity that would otherwise be classified as a partnership is a publicly traded partnership if (1) interests in the partnership are traded on an established securities market or (2) interests in the partnership are readily tradable on a secondary market or the substantial equivalent thereof. We are a publicly traded partnership. However, an exception to taxation as a corporation, referred to as the “Qualifying Income Exception,” exists if at least 90% of such partnership’s gross income for every taxable year consists of “qualifying income” and the partnership is not required to register under the Investment Company Act. Qualifying income includes certain interest income, dividends, real property rents, gains from the sale or other disposition of real property and any gain from the sale or disposition of a capital asset or other property held for the production of income that otherwise constitutes qualifying income.

We intend to manage our affairs so that we will meet the Qualifying Income Exception in each taxable year. We believe we are and will be treated as a partnership and not as a corporation for U.S. federal income tax purposes. It is the opinion of Simpson Thacher & Bartlett LLP that we will be treated as a partnership and not as an association or publicly traded partnership (within the meaning of Section 7704 of the Code) subject to tax as a corporation for U.S. federal income tax purposes based on factual statements and representations made by us, including statements and representations as to the manner in which we intend to manage our affairs and the composition of our income. However, this opinion will be based solely on current law and will not take into account any proposed or potential changes in law, which may be enacted with retroactive effect. Moreover, opinions of counsel are not binding upon the IRS or any court, and the IRS may challenge this conclusion and a court may sustain such a challenge.

If we fail to meet the Qualifying Income Exception, other than for a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery, or if we are required to register under the Investment Company Act, we will be treated as if we had transferred all of our assets, subject to liabilities, to a newly formed corporation on the first day of the year in which we fail to meet the Qualifying Income Exception in return for stock in that corporation, and then distributed the stock to the holders of Series B Preferred units in liquidation of their interests in us. This contribution and liquidation should be tax-free to holders so long as we do not have liabilities in excess of the tax basis of our assets. Thereafter, we would be treated as a corporation for U.S. federal income tax purposes.

If we were treated as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, our items of income, gain, loss and deduction would be reflected only on our tax return rather than being passed through to holders of Series B Preferred units, and we would be subject to U.S. corporate income tax on our taxable income. Distributions made to holders of our Series B Preferred units would

S-43

be treated as either taxable dividend income, which may be eligible for reduced rates of taxation, to the extent of our current or accumulated earnings and profits, or in the absence of earnings and profits, as a nontaxable return of capital, to the extent of the holder’s tax basis in the Series B Preferred units, or as taxable capital gain, after the holder’s basis is reduced to zero. In addition, in the case of non-U.S. Holders, income that we receive with respect to investments may be subject to a higher rate of U.S. withholding tax if we are treated as a corporation. Accordingly, treatment as a corporation could materially reduce a holder’s after-tax return and thus could result in a substantial reduction of the value of the Series B Preferred units.

If at the end of any taxable year we fail to meet the Qualifying Income Exception, we may still qualify as a partnership if we are entitled to relief under the Code for an inadvertent termination of partnership status. This relief will be available if (1) the failure is cured within a reasonable time after discovery, (2) the failure is determined by the IRS to be inadvertent and (3) we agree to make such adjustments (including adjustments with respect to our partners) or to pay such amounts as are required by the IRS. It is not possible to state whether we would be entitled to this relief in any or all circumstances. If this relief provision is inapplicable to a particular set of circumstances involving us, we will not qualify as a partnership for federal income tax purposes. Even if this relief provision applies and we retain our partnership status, we or the holders of our Series B Preferred units (during the failure period) will be required to pay such amounts as are determined by the IRS.

The remainder of this section assumes that Oaktree Capital Group, LLC will be treated as a partnership for U.S. federal income tax purposes.

Taxation of Oaktree Holdings, Inc., Oaktree AIF Holdings, Inc. and Oaktree Holdings, Ltd.

Oaktree Capital Group, LLC holds a portion of its interests in our subsidiaries through Oaktree Holdings, Inc., Oaktree AIF Holdings, Inc. and Oaktree Holdings, Ltd. (the “Corporations”). The Corporations are taxable as corporations for U.S. federal income tax purposes. We are not taxed directly on earnings of entities we hold through the Corporations. Distributions of cash or other property that the Corporations pay to us will constitute dividends for U.S. federal income tax purposes to the extent paid from current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If the amount of a distribution by a Corporation exceeds its current and accumulated earnings and profits, such excess will be treated as a tax-free return of capital to the extent of our tax basis in the Corporation’s stock, and thereafter will be treated as a capital gain.

Each of Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. will incur U.S. federal income taxes on income earned by such Corporation. With respect to Oaktree Holdings, Ltd., we intend to operate Oaktree Holdings, Ltd. to minimize its income that is effectively connected with a U.S. trade or business, or ECI. Oaktree Holdings, Ltd.’s income will not be subject to U.S. federal income tax to the extent it has a foreign source and is not treated as ECI. Oaktree Holdings, Ltd. is a controlled foreign corporation (“CFC”) for U.S. federal income tax purposes subject to the rules described under “—Consequences to U.S. Holders of Series B Preferred Units—Controlled Foreign Corporations.”

Personal Holding Companies

Each of Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. could be subject to additional U.S. federal income tax on a portion of its income if it is determined to be a personal holding company (“PHC”) for U.S. federal income tax purposes. A U.S. corporation will be classified as a PHC for U.S. federal income tax purposes in a given taxable year if (1) at any time during the last half of such taxable year, five or fewer individuals (without regard to their citizenship or residency and including as individuals for this purpose certain entities such as certain tax-exempt organizations and pension funds) own or are deemed to own (pursuant to certain constructive ownership rules) more than 50% of the stock of the corporation by value and (2) at least 60% of the corporation’s adjusted ordinary gross income, as determined for U.S. federal income tax purposes, for such taxable year, consists of PHC income (which includes, among other things, dividends, interest, royalties, annuities and, under certain circumstances, rents). The PHC rules do not apply to non-U.S. corporations. Due to

S-44

applicable attribution rules, it is likely that five or fewer individuals or tax-exempt organizations will be treated as owning actually or constructively more than 50% of the value of the stock in each of Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. Consequently, each of Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. could be or become a PHC, depending on whether it fails the PHC gross income test. Certain aspects of the gross income test cannot be predicted with certainty. Thus, no assurance can be given that Oaktree Holdings, Inc. or Oaktree AIF Holdings, Inc. will not become a PHC in the future.

If Oaktree Holdings, Inc. or Oaktree AIF Holdings, Inc. is or were to become a PHC in a given taxable year, it would be subject to an additional 20% PHC tax on its undistributed PHC income, which includes the company’s taxable income, subject to certain adjustments. If Oaktree Holdings, Inc. or Oaktree AIF Holdings, Inc. were to become a PHC and had significant amounts of undistributed PHC income, the amount of PHC tax could be material; in that event, distribution of such income would reduce the PHC income subject to tax.

Certain State, Local and Non-U.S. Tax Matters

We and our subsidiaries are subject to state, local and non-U.S. taxation in various jurisdictions, including those in which we or they transact business, own property or reside. We may be required to file tax returns in some or all of those jurisdictions. The state, local or non-U.S. tax treatment of us and our holders may not conform to the U.S. federal income tax treatment discussed herein. We may be subject to significant amounts of non-U.S. taxes as a result of our investments and operations. Any non-U.S. taxes incurred by us may not pass through to Series B Preferred unitholders as a credit against their federal income tax liability. For non-corporate U.S. shareholders, the deductibility of state and local taxes will also be subject to substantial limitations for taxable years 2018 through 2025.

Consequences to U.S. Holders of Series B Preferred Units

The following is a summary of the material U.S. federal income tax consequences that will apply to you if you are a U.S. Holder of Series B Preferred units.

Taxation of Holders of Series B Preferred Units on Our Gross Ordinary Income.

As a partnership for tax purposes, we are not a taxable entity and incur no U.S. federal income tax liability except as described below under “—Administrative Matters—Partnership Audit Legislation.” Instead, each holder of Series B Preferred units in computing such holder’s U.S. federal income tax liability for a taxable year will be required to take into account items of gross ordinary income we allocate to it, including any Subpart F income or GILTI (as defined below). We refer to our gross income (excluding any gross income attributable to the sale or exchange of capital assets) as our “gross ordinary income.” In general, to the extent of our gross ordinary income in any taxable year, we will specially allocate to the Series B Preferred units items of our gross ordinary income in an amount equal to the distributions paid in respect of the Series B Preferred units during the taxable year. If the distributions paid in respect of the Series B Preferred units in a taxable year exceed our gross ordinary income, items of our gross ordinary income will be allocated to the Series B Preferred units pro-rata based on the amount of distributions paid in respect of the Series B Preferred units in such taxable year. The gross ordinary income allocated to a holder of Series B Preferred units will generally have the same character as our gross ordinary income (e.g., interest, dividends, rents from real property, UBTI, etc.). To the extent our distributions in prior years exceeded the cumulative gross ordinary income allocated to the Series B Preferred units, we will allocate additional gross ordinary income, to the extent available in any taxable year, to the Series B Preferred units until such excess is eliminated. In such circumstance, the gross ordinary income allocated to holders of the Series B Preferred units during a taxable year would exceed the distributions to the Series B Preferred units during such taxable year. However, we expect we will have sufficient gross ordinary income in calendar year 2018 to allocate gross ordinary income to the Series B Preferred units in an amount equal to the distributions paid on the Series B Preferred units. We believe that for U.S. federal income tax purposes, such allocations will be given effect, and we intend to prepare tax returns based on such allocations. If the IRS

S-45

successfully challenges the allocations made pursuant to our limited liability company agreement, the resulting allocations for U.S. federal income tax purposes might be less favorable than the allocation set forth in the limited liability company agreement. The treatment of interests in a partnership such as the Series B Preferred units and the payments received in respect of such interests is uncertain. The IRS may contend that payments on the Series B Preferred units represent “guaranteed payments,” which would generally be treated as ordinary income and may not have the same character when received by a holder as our gross ordinary income had when earned by us. If distributions on the Series B Preferred units were treated as “guaranteed payments,” a holder would always be treated as receiving income equal to the amount distributed or accrued, regardless of the amount of our gross ordinary income. Holders of Series B Preferred units are encouraged to consult their own tax advisors regarding the treatment of payments on the Series B Preferred units as “guaranteed payments.”

With respect to U.S. Holders who are individuals, certain dividends paid by Oaktree Holdings, Inc., Oaktree AIF Holdings Inc. or certain qualified foreign corporations to us and that are allocable to such U.S. Holders may be subject to reduced rates of taxation. A qualified foreign corporation includes a foreign corporation that is eligible for the benefits of specified income tax treaties with the United States. In addition, a foreign corporation is treated as a qualified corporation with respect to shares that are readily tradable on an established securities market in the United States. Among other exceptions, a U.S. Holder who is an individual will not be eligible for reduced rates of taxation on any dividend if the payer is a passive foreign investment company (“PFIC”) (as defined below) in the taxable year in which such dividend is paid or in the preceding taxable year or on any income required to be reported by the U.S. Holder as a result of a QEF election (as defined below) that is attributable to an entity that is a PFIC and in which we hold a direct or indirect interest. Dividends paid by Oaktree Holdings, Ltd. and Subpart F and GILTI inclusions attributable to Oaktree Holdings, Ltd. will not be eligible for such reduced rates of taxation. Prospective investors should consult their own tax advisers regarding the application of the foregoing rules to their particular circumstances.

U.S. Holders that are individuals, estates or trusts are subject to a Medicare tax of 3.8% on “net investment income” (or undistributed “net investment income,” in the case of estates and trusts) for each taxable year, with such tax applying to the lesser of such income or the excess of such person’s adjusted gross income (with certain adjustments) over a specified amount. Net investment income includes net income from interest, dividends, annuities, royalties and rents and net gain attributable to the disposition of investment property. Net income and gain attributable to an investment in our Series B Preferred units will be included in a U.S. Holder’s “net investment income” subject to this Medicare tax.

Basis

You will have an initial tax basis for your Series B Preferred unit equal to the amount you paid for the Series B Preferred unit. That basis will be increased by your share of our gross ordinary income. That basis will be decreased, but not below zero, by distributions from us.

Holders who purchase Series B Preferred units in separate transactions must combine the basis of those units and maintain a single adjusted tax basis for all those units. Upon a sale or other disposition of less than all of the Series B Preferred units, a portion of that tax basis must be allocated to the Series B Preferred units sold.

Treatment of Distributions

Distributions of cash by us generally will not be taxable to you to the extent of your adjusted tax basis (described above) in your Series B Preferred units. Any cash distributions in excess of your adjusted tax basis will be considered to be gain from the sale or exchange of Series B Preferred units (described below). Under current laws, such gain would be treated as capital gain and would be long-term capital gain if your holding period for your Series B Preferred units exceeds one year, subject to certain exceptions (described below).

S-46

Sale or Exchange of Series B Preferred Units

You will recognize gain or loss on a sale of Series B Preferred units equal to the difference, if any, between the amount realized and your tax basis in the Series B Preferred units sold.

Gain or loss recognized by you on the sale or exchange of a Series B Preferred unit will be taxable as capital gain or loss and will be long-term capital gain or loss if all of the Series B Preferred units you hold were held for more than one year on the date of such sale or exchange. The deductibility of capital losses is subject to limitations.

Holders who purchase Series B Preferred units at different times and intend to sell all or a portion of the units within a year of their most recent purchase are urged to consult their tax advisers regarding the application of certain “split holding period” rules to them and the treatment of any gain or loss as long-term or short-term capital gain or loss. Holders in publicly traded partnerships may choose to use the actual holding period for each unit sold provided certain requirements are met. You should consult your tax adviser regarding these rules.

Foreign Tax Credit Limitations

You may be entitled to a foreign tax credit with respect to your allocable share of creditable foreign taxes paid on our gross ordinary income. Complex rules may, depending on your particular circumstances, limit the availability or use of foreign tax credits. Certain losses that we incur may be treated as foreign source losses, which could reduce the amount of foreign tax credits otherwise available. You should consult your tax adviser with respect to whether you will be entitled to any foreign tax in light of your particular circumstances.

Tax Accounting Methods

We have tax accounting positions that may not conform with all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could have a negative impact on our Series B Preferred units or result in audits of and adjustments to our Series B Preferred unitholders’ tax returns.

Foreign Currency Gain or Loss

Our functional currency is the U.S. dollar, and our income or loss is calculated in U.S. dollars. It is likely that we will recognize “foreign currency” gain or loss with respect to transactions involving non-U.S. dollar currencies. In general, foreign currency gain or loss is treated as ordinary income or loss. You should consult your tax adviser with respect to the tax treatment of foreign currency gain or loss.

Passive Foreign Investment Companies

You may be subject to special rules applicable to indirect investments in foreign corporations, including an investment in a PFIC.

A PFIC is defined as any foreign corporation with respect to which either (1) 75% or more of the gross income for a taxable year is “passive income” or (2) 50% or more of its assets in any taxable year (in most instances based on the quarterly average of the value of its assets) produce “passive income.” There are no minimum stock ownership requirements for PFICs. Once a corporation qualifies as a PFIC, it is, with respect to a shareholder of the corporation during the time it qualifies as a PFIC, and absent certain taxpayer elections to recognize taxable income or gains, always treated as a PFIC with respect to such shareholder, regardless of whether it satisfies either of the qualification tests in subsequent years. In the case of PFICs, the share of a U.S. Holder of certain distributions from such corporations could be subject to an interest charge and certain other disadvantageous tax treatment. If we make a QEF election with respect to a PFIC, each U.S. Holder would avoid the interest charge described above. We cannot give any assurance that the QEF election will be available with respect to a PFIC that we invest in or that we will make a QEF election.

S-47

Controlled Foreign Corporations

A non-U.S. entity will be treated as a CFC if it is treated as a corporation for U.S. federal income tax purposes and if more than 50% of (1) the total combined voting power of all classes of stock of the non-U.S. entity entitled to vote or (2) the total value of the stock of the non-U.S. entity is owned by U.S. Shareholders on any day during the taxable year of such non-U.S. entity. For purposes of this discussion, a “U.S. Shareholder” with respect to a non-U.S. entity means a U.S. person that owns 10% or more of the total combined voting power of all classes of stock of the non-U.S. entity entitled to vote or 10% or more of the total value of shares of all classes of stock of the non-U.S. entity.

When making investment or other decisions, we will consider whether an investment will be a CFC and the consequences related thereto. If we are a U.S. Shareholder in a non-U.S. entity that is treated as a CFC, each Series B Preferred unitholder’s allocable share of gross ordinary income may include the CFC’s “Subpart F” income reported by us. Subpart F income includes dividends, interest, net gain from the sale or disposition of securities, non-actively managed rents, fees for services provided to certain related persons and certain other passive types of income. The aggregate Subpart F income inclusions in any taxable year relating to a particular CFC are limited to such entity’s current earnings and profits. These inclusions are treated as ordinary income (whether or not such inclusions are attributable to net capital gains). Such income will not be eligible for the reduced rate of tax applicable to “qualified dividend income” for individual U.S. persons. See the introduction to this “—Consequences to U.S. Holders of Series B Preferred Units” section. Amounts included as such income with respect to direct and indirect investments will not be taxable again when actually distributed.

If a non-U.S. entity held by us is classified as both a CFC and a PFIC during the time we are a U.S. Shareholder of such non-U.S. entity, a holder will be required to include amounts in income with respect to such non-U.S. entity pursuant to this subheading, and the consequences described under the subheading “—Passive Foreign Investment Companies” above will not apply. If our ownership percentage in a non-U.S. entity changes such that we are not a U.S. Shareholder with respect to such non-U.S. entity, then Series B Preferred unitholders may be subject to the PFIC rules. The interaction of these rules is complex, and prospective holders are urged to consult their tax advisers in this regard.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law. Under the Tax Act, effective for the first tax year of a CFC beginning after December 31, 2017, any U.S. person who is a U.S. Shareholder of a CFC is taxed currently on its share of the CFC’s global intangible low-taxed income (“GILTI”). GILTI is generally defined to include most business income of a CFC reduced by 10% of the adjusted basis of the CFC’s depreciable tangible property. A U.S. Shareholder that is not a corporation for U.S. federal income tax purposes is subject to tax on such U.S. Shareholder’s share of a CFC’s GILTI at a significantly higher rate than U.S. Shareholders that are corporations for U.S. federal income tax purposes.

Oaktree Holdings, Ltd. is a CFC subject to the foregoing rules and as such, each Series B Preferred unitholder that is a U.S. person will be required to include in income its share of Oaktree Holdings, Ltd.’s Subpart F and GILTI income reported by us.

Investment Structure

To manage our affairs so as to meet the Qualifying Income Exception and comply with certain requirements in our operating agreement, we may need to structure certain investments through an entity classified as a corporation for U.S. federal income tax purposes. Such investment structures will be entered into as determined in the sole judgment of our board of directors in order to create a tax structure that we expect will be efficient for our Series B Preferred unitholders. However, because our Series B Preferred unitholders will be located in numerous taxing jurisdictions, no assurances can be given that any such investment structure will be beneficial to all our Series B Preferred unitholders to the same extent, and may even impose additional tax burdens on some of our Series B Preferred unitholders. As discussed above, if the entity were a non-U.S. corporation it may be

S-48

considered a PFIC or a CFC. If the entity were a U.S. corporation, it would be subject to U.S. federal income tax on its operating income, including any gain recognized on its disposal of its investments. In addition, if the investment involves U.S. real estate, gain recognized on disposition would be subject to such tax, whether the corporation is a U.S. or a non-U.S. corporation.

Taxes in Other State, Local, and Non-U.S. Jurisdictions

In addition to U.S. federal income tax consequences, you may be subject to potential U.S. state and local taxes because of an investment in us in the U.S. state or locality in which you are a resident for tax purposes or in which we have investments or activities. You may also be subject to tax return filing obligations and income, franchise or other taxes, including withholding taxes, in state, local or non-U.S. jurisdictions in which we invest, or in which entities in which we own interests conduct activities or derive income. Income or gains from investments held by us may be subject to withholding or other taxes in jurisdictions outside the United States, subject to the possibility of reduction under applicable income tax treaties. If you wish to claim the benefit of an applicable income tax treaty, you may be required to submit information to tax authorities in such jurisdictions. You should consult your own tax advisers regarding the U.S. state, local and non-U.S. tax consequences of an investment in us.

Transferor/Transferee Allocations

Our taxable income and losses will be determined and apportioned among investors using conventions we regard as consistent with applicable law. As a result, if you transfer your Series B Preferred units, you may be allocated gross ordinary income realized by us after the date of transfer.

Although Section 706 of the Code provides guidelines for allocations of items of partnership income and deductions between transferors and transferees of partnership interests, it is not clear that our allocation method complies with its requirements. If our convention were not permitted, the IRS might contend that our gross ordinary income must be reallocated among the holders of Series B Preferred units. If such a contention were sustained, your respective tax liabilities would be adjusted to your possible detriment. Our board of directors is authorized to revise our method of allocation between transferors and transferees (as well as among investors whose interests otherwise vary during a taxable period).

Deduction for Certain Qualified Business Income

Under the Tax Act, individual taxpayers may be allowed a deduction of 20% of certain domestic business income (excluding capital gains, dividend income, and certain types of compensation) received from publicly traded partnerships. We expect that a substantial amount of our income may not be eligible for the deduction.

U.S. Federal Estate Taxes

If Series B Preferred units are included in the gross estate of a U.S. citizen or resident for U.S. federal estate tax purposes, then a U.S. federal estate tax might be payable in connection with the death of such person. Prospective individual U.S. Holders should consult their own tax advisers concerning the potential U.S. federal estate tax consequences with respect to our Series B Preferred units.

U.S. Taxation of Tax-Exempt U.S. Holders of Series B Preferred Units

A holder of Series B Preferred units that is a tax-exempt entity for U.S. federal income tax purposes (including an individual retirement account or 401(k) plan participant) and therefore exempt from most U.S. federal income taxation will nevertheless be subject to “unrelated business income tax” to the extent, if any, that its share of our gross ordinary income consists of “unrelated business taxable income,” or UBTI. A tax-exempt partner of a partnership that regularly engages in a trade or business which is unrelated to the exempt function of

S-49

the tax-exempt partner must include in computing its UBTI its share (whether or not distributed) of such partnership’s gross income derived from such unrelated trade or business. Moreover, a tax-exempt partner of a partnership could be treated as earning UBTI to the extent that such partnership derives income from “debt-financed property,” or if the partnership interest itself is debt financed. Debt-financed property means property held to produce income with respect to which there is “acquisition indebtedness” (that is, indebtedness incurred in acquiring or holding property). We will make investments through entities classified as partnerships or disregarded entities for U.S. federal income tax purposes in debt-financed property and, thus, an investment in Series B Preferred units will give rise to UBTI to tax-exempt holders of Series B Preferred units.

Additionally, as a result of changes introduced by the Tax Act, a tax-exempt holder will be required to calculate UBTI separately with respect to each trade or business in which it has an interest and will not be able to use a net operating loss from one trade or business to offset UBTI from another trade or business. Accordingly, losses generated by one operating pass-through entity, in which such tax-exempt holder has an interest, may not be used to reduce UBTI generated by another operating pass-through entity in which such tax-exempt holder has an interest, and such loss must instead be carried forward to subsequent years to offset UBTI generated by the same operating pass-through entity. The use of a net operating loss arising in a taxable year beginning before January 1, 2018, is not subject to such limitation. It is unclear how this limitation will apply to income from investments that are “debt-financed.”

Because we are under no obligation to minimize UBTI, tax-exempt U.S. Holders of Series B Preferred units should consult their own tax advisers regarding all aspects of UBTI.

Investments by U.S. Mutual Funds

U.S. mutual funds that are treated as regulated investment companies, or RICs, for U.S. federal income tax purposes are required, among other things, to meet an annual 90% gross income and a quarterly 50% asset value test under Section 851(b) of the Code to maintain their favorable U.S. federal income tax status. The treatment of an investment by a RIC in Series B Preferred units for purposes of these tests will depend on whether we are treated as a “qualifying publicly traded partnership.” If our limited liability company is so treated, then the Series B Preferred units themselves are the relevant assets for purposes of the 50% asset value test and the net income from the Series B Preferred units is the relevant gross income for purposes of the 90% gross income test. RICs may not invest greater than 25% of their assets in one or more qualifying publicly traded partnerships. All income derived from a qualifying publicly traded partnership is considered qualifying income for purposes of the RIC 90% gross income test described above. However, if we are not treated as a qualifying publicly traded partnership for purposes of the RIC rules, then the relevant assets for the RIC asset test will be the RIC’s allocable share of the underlying assets held by us and the relevant gross income for the RIC income test will be the RIC’s allocable share of the underlying gross income earned by us. Whether we will qualify as a “qualifying publicly traded partnership” depends on the exact nature of our future investments, but we do not expect to be treated as a “qualifying publicly traded partnership.” RICs should consult their own tax advisers about the U.S. tax consequences of an investment in Series B Preferred units.

Consequences to Non-U.S. Holders of Series B Preferred Units

U.S. Income Tax Consequences

In light of our intended investment activities, we may 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 (“ECI”) with respect to non-U.S. Holders. 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 certain non-U.S. Holders. We expect that we will earn ECI and/or income treated as ECI.

S-50

To the extent our income is treated as ECI, non-U.S. Holders would be (1) subject to withholding tax on their allocable share of such income, (2) required to file a U.S. federal income tax return for such year reporting their allocable share, if any, of income or loss effectively connected with such trade or business, including certain income from U.S. sources not related to us, and (3) required to pay U.S. federal income tax at regular U.S. federal income tax rates on any such income. Moreover, a corporate non-U.S. Holder might be subject to a U.S. branch profits tax on its allocable share of its ECI. Any amount so withheld would be creditable against such non-U.S. Holder’s U.S. federal income tax liability, and such non-U.S. Holder could claim a refund to the extent that the amount withheld exceeded such non-U.S. Holder’s U.S. federal income tax liability for the taxable year.

If we are treated as being engaged in a U.S. trade or business, any gain recognized by a non-U.S. Holder on the sale or exchange of Series B Preferred units that is attributable to assets that if sold would produce income that would be effectively connected with such U.S. trade or business will be treated for U.S. federal income tax purposes as ECI, and hence, such Series B Preferred unitholders would be subject to U.S. federal income tax on the sale or exchange of such Series B Preferred units. Under the Tax Act, unless an applicable non-foreign affidavit is furnished or other exception applies, if any portion of gain, if any, on a disposition of Series B Preferred units would be treated as ECI, the transferee of an interest in us is required to withhold 10% of the amount realized on such disposition (and we may be required to withhold from future distributions to the transferee if the transferee fails to properly withhold). Even if a non-U.S. holder disposes of its shares in a transaction that otherwise qualifies as a non-recognition transaction, such non-U.S. holder may recognize gain and be subject to the withholding if we are treated as engaged in a U.S. trade or business. The U.S. Treasury Department has the regulatory authority to prescribe circumstances in which certain non-recognition provisions will continue to apply to defer the recognition of gain. In addition, the U.S. Treasury Department and the IRS recently released a notice suspending the withholding requirements described above for interests in publicly traded partnerships, such as us, until such time as regulations or other guidance have been issued. As a result, it is unclear how this provision may impact transfers of Series B Preferred units in the future.

Such withholding tax provisions, when effective for publicly traded partnerships, could impose material tax and administrative burdens on us and our Series B Preferred unitholders.

To the extent we receive dividends from a U.S. corporation through the Oaktree Operating Group and its investment vehicles, your share of distributions of such dividend income will be subject to U.S. withholding tax at a rate of 30%, unless you are eligible for a reduced rate of such withholding and provide us with certain relevant tax status information. Distributions to you may also be subject to withholding to the extent they are considered fixed or determinable annual or periodic income under the Code, provided that an exemption from or a reduced rate of such withholding may apply if certain tax status information is provided. If such information is not provided and you would not be subject to U.S. tax based on your tax status or are eligible for a reduced rate of U.S. withholding, you may need to take additional steps to receive a credit or refund of any excess withholding tax paid on your account, which may include the filing of a non-resident U.S. income tax return with the IRS. Among other limitations, if you reside in a treaty jurisdiction which does not treat our limited liability company as a pass-through entity, you may not be eligible to receive a refund or credit of excess U.S. withholding taxes. You should consult your tax advisers regarding the treatment of U.S. withholding taxes.

Special rules may apply in the case of a non-U.S. Holder that (1) has an office or fixed place of business in the United States, (2) is present in the United States for 183 days or more in a taxable year or (3) is a former citizen of the United States, a foreign insurance company that is treated as holding interests in us in connection with their U.S. business, a PFIC or a corporation that accumulates earnings to avoid U.S. federal income tax. You should consult your tax advisers regarding the application of these special rules.

U.S. Federal Estate Tax Consequences

The U.S. federal estate tax treatment of our Series B Preferred units with regards to the estate of a non-citizen who is not a resident of the United States is not entirely clear. If our Series B Preferred units are

S-51

includable in the U.S. gross estate of such person, then a U.S. federal estate tax might be payable in connection with the death of such person. Prospective individual non-U.S. Holders who are non-citizens and not residents of the United States should consult their own tax advisers concerning the potential U.S. federal estate tax consequences with regard to our units.

Administrative Matters

Taxable Year

We currently use the calendar year as our taxable year for U.S. federal income tax purposes. Under certain circumstances which we currently believe are unlikely to apply, a taxable year other than the calendar year may be required for such purposes.

Tax Matters Member and Partnership Representative

OCGH acts as our “tax matters member” or “partnership representative,” as applicable. As the tax matters member or partnership representative, OCGH has the authority, subject to certain restrictions, to act on our behalf in connection with any administrative or judicial review of our items of income, gain, loss, deduction or credit.

Information Returns

It may require a substantial period of time after the end of our fiscal year to obtain the requisite information from all lower-tier entities to enable us to prepare and deliver Schedule K-1s to IRS Form 1065. If we cannot provide timely Schedule K-1s, we expect to provide estimates of such tax information (including your allocable share of gross ordinary income for our preceding year) by the deadline for filing U.S. income tax returns each year; in that event, however, there is no assurance that the Schedule K-1s, which would be provided after the estimates, will be the same as our estimates. For this reason, holders of Series B Preferred units who are U.S. taxpayers may want to file annually with the IRS (and certain states) a request for an extension past the due date of their income tax return.

In addition, in the event we provide separate estimates and subsequent Schedule K-1s, it is possible that a Series B Preferred 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 of a Series B Preferred 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, is the responsibility of each Series B Preferred unitholder.

In preparing this information, we will use various accounting and reporting conventions, some of which have been mentioned in the previous discussion, to determine your share of income, gain, loss and deduction. The IRS may successfully contend that certain of these reporting conventions are impermissible, which could result in an adjustment to your income or loss.

We may be audited by the IRS. Adjustments resulting from an IRS audit may require you to adjust a prior year’s tax liability and possibly may result in an audit of your own tax return. Any audit of your tax return could result in adjustments not related to our tax returns as well as those related to our tax returns.

Tax Shelter Regulations

If we were to engage in a “reportable transaction,” we (and possibly you and others) would be required to make a detailed disclosure of the transaction to the IRS in accordance with recently issued regulations governing tax shelters and other potentially tax-motivated transactions. A transaction may be a reportable transaction based upon any of several factors, including the fact that it is a type of tax avoidance transaction publicly identified by

S-52

the IRS as a “listed transaction” or that it produces certain kinds of losses in excess of $2 million. An investment in us may be considered a reportable transaction if, for example, we recognize certain significant losses in the future. In certain circumstances, a Series B Preferred unitholder who disposes of an interest in a transaction resulting in the recognition by such holder of significant losses in excess of certain threshold amounts may be obligated to disclose its participation in such transaction. Our participation in a reportable transaction also could increase the likelihood that our U.S. federal income tax information return (and possibly your tax return) would be audited by the IRS. Certain of these rules are currently unclear and it is possible that they may be applicable in situations other than significant loss transactions.

Moreover, if we were to participate in a reportable transaction with a significant purpose to avoid or evade tax, or in any listed transaction, you may be subject to (1) significant accuracy-related penalties with a broad scope, (2) for those persons otherwise entitled to deduct interest on federal tax deficiencies, nondeductibility of interest on any resulting tax liability and (3) in the case of a listed transaction, an extended statute of limitations.

Series B Preferred unitholders should consult their tax advisers concerning any possible disclosure obligation under the regulations governing tax shelters with respect to the dispositions of their interests in us.

Withholding and Backup Withholding

For each calendar year, we will report to you and the IRS the amount of distributions we made to you and the amount of U.S. federal income tax (if any) that we withheld on those distributions. The proper application to us of rules for withholding under Section 1441 of the Code (applicable to certain dividends, interest and similar items) is unclear. Because the documentation we receive may not properly reflect the identities of partners at any particular time (in light of possible sales of Series B Preferred units), we may over-withhold or under-withhold with respect to a particular holder of Series B Preferred units. For example, we may impose withholding, remit that amount to the IRS and thus reduce the amount of a distribution paid to a non-U.S. Holder. It may turn out, however, the corresponding amount of our income was not properly allocable to such holder, and the withholding should have been less than the actual withholding. Such holder would be entitled to a credit against the holder’s U.S. tax liability for all withholding, including any such excess withholding, but if the withholding exceeded the holder’s U.S. tax liability, the holder would have to apply for a refund to obtain the benefit of the excess withholding. Similarly, we may fail to withhold on a distribution, and it may turn out the corresponding income was properly allocable to a non-U.S. Holder and withholding should have been imposed. In that event, we intend to pay the under-withheld amount to the IRS, and we may treat such under-withholding as an expense that will be borne by all holders of Series B Preferred units on a pro-rata basis (since we may be unable to allocate any such excess withholding tax cost to the relevant non-U.S. Holder).

Under the backup withholding rules, you may be subject to backup withholding tax (at the rate of 24%) with respect to distributions paid unless: (1) you are a corporation or come within another exempt category and demonstrate this fact when required or (2) you provide a taxpayer identification number, certify as to no loss of exemption from backup withholding tax and otherwise comply with the applicable requirements of the backup withholding tax rules. If you are an exempt holder, you should indicate your exempt status on a properly completed IRS Form W-9. A non-U.S. Holder may qualify as an exempt recipient by submitting a properly completed IRS Form W-8BEN or Form W-8 BEN-E. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund.

If an investor does not timely provide us (or the clearing agent or other intermediary, as appropriate) with IRS Form W-8 or W-9, as applicable, or such form is not properly completed, we may become subject to U.S. backup withholding taxes in excess of what would have been imposed had we received certifications from all investors. Such excess U.S. backup withholding taxes may be treated by us as an expense that will be borne by all investors on a pro-rata basis (since we may be unable to allocate any such excess withholding tax cost to the holders that failed to timely provide the proper U.S. tax certifications).

S-53

Additional Withholding Requirements

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% U.S. withholding tax may apply to certain payments or, for a disposition occurring after December 31, 2018, the gross proceeds from a disposition of any U.S. stock or securities, in each case paid to (i) a “foreign financial institution” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial U.S. beneficial owners of such entity (if any). Non-U.S. and U.S. Holders are encouraged to consult their own tax advisors regarding the implications of FATCA on their investment in our Series B Preferred units.

Nominee Reporting

Persons who hold an interest in our limited liability company as a nominee for another person are required to furnish to us:

Brokers and financial institutions are required to furnish additional information, including whether they are U.S. persons and specific information on Series B Preferred units they acquire, hold or transfer for their own account. A penalty of $50 per failure, up to a maximum of $100,000 per calendar year, is imposed by the Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the Series B Preferred units with the information furnished to us.

Partnership Audit Legislation

Legislation was enacted that significantly changes the rules for U.S. federal income tax audits of partnerships. Such audits will continue to be conducted at the partnership level, but with respect to tax returns for taxable years beginning after December 31, 2017, and, unless a partnership qualifies for and affirmatively elects an alternative procedure, any adjustments to the amount of tax due (including interest and penalties) will be payable by the partnership. Under an alternative procedure, if elected, a partnership would issue information returns to persons who were partners in the audited year, who would then be required to take the adjustments into account in calculating their own tax liability, and the partnership would not be liable for the adjustments. If we are able to and in fact elect the alternative procedure for a given adjustment, the amount of taxes for which such persons will be liable will be increased by any applicable penalties and a special interest charge.

There can be no assurance that we will be eligible to make such an election or that we will, in fact, make such an election for any given adjustment. If we do not or are unable to make such an election, then (1) the then current holders of the Series B Preferred units, in the aggregate, could indirectly bear income tax liabilities in excess of the aggregate amount of taxes that would have been due had we elected the alternative procedure, and (2) a given holder may indirectly bear taxes attributable to income allocable to other holders or former holders,

S-54

including taxes (as well as interest and penalties) with respect to periods prior to such holder’s ownership of the Series B Preferred units. Accordingly, it is possible that a holder will bear tax liabilities unrelated to its ownership of the Series B Preferred units. Amounts available for distribution to the holders of the Series B Preferred units may be reduced as result of our obligations to pay any taxes associated with an adjustment.

The partnership representative of OCG will be the only person with the authority to act on our behalf with respect to audits and certain other tax matters and may decide not to elect (or may be unable to elect) the alternative procedure for any particular adjustment. In addition, we and each holder will be bound by the actions taken by the partnership representative on our behalf during any audit or litigation proceeding concerning U.S. federal income taxes.

Many issues and the overall effect of this legislation on us are uncertain, and holders should consult their own tax advisors regarding all aspects of this legislation as it affects their particular circumstances.

New Legislation or Administrative or Judicial Action

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process, the 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. No assurance can be given as to whether, or in what form, any proposals affecting us or our Series B Preferred unitholders will be enacted.

In particular, there is limited guidance regarding the application and interpretation of the Tax Act, and as a result, there is significant uncertainty regarding how the provisions of the Tax Act will be interpreted. In addition, it is possible that technical corrections legislation may be passed during 2018 that could alter or clarify the Tax Act, likely with retroactive effect. There can be no assurance, however, that technical clarifications or other legislative changes that may be needed to prevent unintended or unforeseen adverse tax consequences will be enacted by Congress.

In addition, the present U.S. federal income tax treatment of an investment in our Series B Preferred units may be modified by administrative, legislative or judicial interpretation at any time, and any such action may affect 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 Qualifying Income Exception for us to be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, affect or cause us to change our investments and commitments, affect the tax considerations of an investment in us and adversely affect an investment in our Series B Preferred units. See “Risk Factors—Risks Relating to United States Taxation” in our most recent Annual Report on Form 10-K. We and our Series B Preferred unitholders could be adversely affected by any such change in, or any new, tax law, regulation or interpretation.

Our organizational documents and agreements permit our board of directors to modify the amended and restated operating agreement from time to time, without the consent of the Series B Preferred unitholders, in order 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 of our Series B Preferred unitholders.

THE FOREGOING DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING. THE TAX MATTERS RELATING TO US AND OUR UNITHOLDERS ARE COMPLEX AND ARE SUBJECT TO VARYING INTERPRETATIONS. MOREOVER, THE EFFECT OF EXISTING INCOME TAX LAWS, THE MEANING AND IMPACT OF WHICH IS UNCERTAIN AND OF PROPOSED CHANGES IN INCOME TAX LAWS WILL VARY WITH THE PARTICULAR CIRCUMSTANCES OF EACH PROSPECTIVE HOLDER AND IN REVIEWING THIS PROSPECTUS THESE MATTERS SHOULD BE CONSIDERED. PROSPECTIVE UNITHOLDERS SHOULD CONSULT THEIR TAX ADVISERS WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND OTHER TAX CONSEQUENCES OF ANY INVESTMENT IN THE SERIES B PREFERRED UNITS.

S-55

CERTAIN ERISA AND RELATED CONSIDERATIONS

A fiduciary of a pension, profit-sharing or other employee benefit plan subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended, ERISA (each, an “ERISA Plan”), should consider the fiduciary standards of ERISA in the context of the ERISA Plan’s particular circumstances before authorizing an investment in the Series B Preferred units. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA, would be consistent with its fiduciary responsibilities and with the documents and instruments governing the ERISA Plan, and would involve a prohibited transaction under ERISA or the Code.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans, as well as individual retirement accounts (“IRAs”, each an “IRA”), Keogh plans and any other plans that are subject to Section 4975 of the Code (together with ERISA Plans, “Plans”), from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to the Plan. A violation of these prohibited transaction rules may result in an excise tax or other liabilities under ERISA or the Code for those persons, unless exemptive relief is available under an applicable statutory, regulatory or administrative exemption.

Whether or not the underlying assets of Oaktree Capital Group, LLC, as issuer of the Series B Preferred units, were deemed to include “plan assets,” as described below, we, certain of our subsidiaries and the underwriters, the transfer agent, registrar and paying agent, our manager and our and their respective affiliates may each be considered a “party in interest” or a “disqualified person” with respect to many Plans. Prohibited transactions within the meaning of ERISA or the Code could arise, for example, if the Series B Preferred units are acquired by or with the assets of a Plan with respect to which our manager, we or any of our subsidiaries or our or our manager’s respective affiliates and the other persons referenced above is a party in interest or disqualified person, unless the transaction qualifies for an exemption from the prohibited transaction rules.

Exemptive relief from the prohibited transaction rules under Section 406 of ERISA and Section 4975 of the Code may be available for direct or indirect prohibited transactions resulting from the purchase, holding or disposition of our units. Exemptions that potentially could apply include PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 95-60 (for transactions involving certain insurance company general accounts), and PTCE 96-23 (for transactions managed by in-house asset managers). In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide exemptive relief for certain arm’s-length transactions with a person (other than a fiduciary or an affiliate of a fiduciary that (directly or indirectly) has or exercises discretionary authority or control or renders investment advice with respect to the assets involved in the transaction) that is a party in interest or disqualified person solely by reason of providing services to Plans or being an affiliate of such a service provider (the “Service Provider Exemption”). Each of the above-noted exemptions contains conditions and limitations on its application. Fiduciaries of Plans considering acquiring and/or holding the Series B Preferred units in reliance on these or any other exemption should carefully review the exemption to assure it is applicable. There can be no assurance that any of the class exemptions, the Service Provider Exemption or any other exemption will be available with respect to any particular transaction involving the Series B Preferred units or that all of the conditions of any such exemptions will be satisfied.

S-56

Plan Asset Issues

Regulations, promulgated under ERISA by the U.S. Department of Labor, as modified by Section 3(42) of ERISA (the “Plan Asset Regulations”) generally provide, that when a Plan acquires an equity interest in an entity that is neither a “publicly offered security” nor a security issued by an investment company registered under the 1940 Act, the Plan’s assets include both the equity interest and an undivided interest in each of the underlying assets of the entity unless it is established either that equity participation in the entity by “benefit plan investors” is not significant or that the entity is an “operating company,” in each case, as defined in the Plan Asset Regulations. For purposes of the Plan Asset Regulations, equity participation in an entity by benefit plan investors will not be significant if they hold, in the aggregate, less than 25% of the total value of each class of such entity’s equity, excluding equity interests held by persons (other than benefit plan investors) with discretionary authority or control over the assets of the entity or who provide investment advice for a fee (direct or indirect) with respect to such assets, and any affiliates thereof. Under the Plan Asset Regulation, Plans, including any entity whose underlying assets are regarded as plan assets by reason of any Plan’s investment in the entity, are “benefit plan investors.” Any such entity, or any other entity whose assets are regarded as assets of a Non-ERISA Arrangement under applicable Similar Laws, (collectively, “Plan Asset Entities”).

For purposes of the Plan Asset Regulations, a “publicly offered security” is a security that is (a) “freely transferable”, (b) part of a class of securities that is “widely held,” and (c) (i) sold to a Plan as part of an offering of securities to the public pursuant to an effective registration statement under the Securities Act and the class of securities to which such security is a part is registered under the Exchange Act within 120 days after the end of the fiscal year of the issuer during which the offering of such securities to the public has occurred, or (ii) is part of a class of securities that is registered under Section 12 the Exchange Act. The Series B Preferred units are being offered pursuant to a registered offering under the Securities Act, and the Series B Preferred units will be registered under the Exchange Act. The Plan Asset Regulations provide that a security is “widely held” only if it is part of a class of securities that is owned by 100 or more investors independent of the issuer and one another. A security will not fail to be “widely held” because the number of independent investors falls below 100 subsequent to the initial offering thereof as a result of events beyond the control of the issuer. It is anticipated that our Series B Preferred units will be “widely held” within the meaning of the Plan Asset Regulations, although no assurance can be given in this regard. The Plan Asset Regulations provide that, whether a security is “freely transferable” is a factual question to be determined on the basis all the relevant facts and circumstances. It is anticipated that our Series B Preferred units will be “freely transferable” within the meaning of the Plan Asset Regulations, although no assurance can be given in this regard.

Accordingly, although no assurances can be given in this regard, we anticipate that the Series B Preferred units we are selling hereunder should qualify as a “publicly offered security” within the meaning of the Plan Asset Regulations.

Employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) (collectively, “Non-ERISA Arrangements”) are not subject to the fiduciary responsibility provisions of Title I of ERISA or the prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code, but may be subject to substantially similar provisions under applicable federal, state, local, non-U.S. or other laws (“Similar Laws”). Fiduciaries of any such Non-ERISA Arrangements should consult with their counsel before purchasing the Series B Preferred units.

Plan Asset Consequences

If the assets of Oaktree Capital Group, LLC, as issuer of the Series B Preferred units, were deemed to be “plan assets” under ERISA, this would result, among other things, in (i) the unintended application of the prudence and other fiduciary responsibility standards of ERISA to investments made by Oaktree Capital Group, LLC and (ii) the possibility that certain transactions in which Oaktree Capital Group, LLC, might seek to engage

S-57

could constitute “prohibited transactions” under ERISA and the Code. Violations of these rules could result in liabilities for, among others, Oaktree Capital Group, LLC and parties related to or dealing with it, and Plan fiduciaries.

Certain Restrictions

Due to the foregoing requirements, the Series B Preferred units may not be purchased or held by any Plan, Plan Asset Entity, or any person investing plan assets of any Plan or Non-ERISA Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under Section 406 of ERISA and Section 4975 of the Code or a violation of any applicable Similar Law.

Accordingly, each purchaser and subsequent transferee, including any fiduciary purchasing or holding the Series B Preferred units with the assets of any Plan, Plan Asset Entity or Non-ERISA Arrangement will be deemed to have represented by its purchase or holding of the Series B Preferred units offered hereby or any interest therein that it either (a) is not a Plan, Plan Asset Entity or a Non-ERISA Arrangement and is not purchasing or holding the Series B Preferred units on behalf of or with the assets of any Plan, Plan Asset Entity or Non-ERISA Arrangement or (b) the purchase and holding of the Series B Preferred units will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws.

The following representations are intended to comply with the U.S. Department of Labor’s Reg. Sections 29 C.F.R. 2510.3-21(a) and (c)(1) as promulgated on April 8, 2016 (81 Fed. Reg. 20,997). If these regulations are revoked, repealed or no longer effective, these representations shall be deemed to be no longer in effect. Any purchaser of the Series B Preferred units in this offering or any interest therein that is a Plan or Plan Asset Entity and that acquires Series B Preferred units in connection with this offering will, by its purchase of the Series B Preferred units offered hereby, be deemed to represent, warrant and acknowledge, for so long as it holds such investment that a fiduciary (the “Fiduciary”) independent of us, our manager, the underwriters or our or their respective affiliates (the “Transaction Parties”) acting on behalf of the Plan or Plan Asset Entity is responsible for the decision of the Plan or Plan Asset Entity to acquire and hold the Series B Preferred units in this offering and that such Fiduciary:

S-58

The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is important that fiduciaries or other persons considering purchasing Series B Preferred units on behalf of or with the assets of any Plan, Plan Asset Entity or Non-ERISA Arrangement consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether such investment will constitute or result in a prohibited transaction or any other violation of an applicable requirement of ERISA, Section 4975 of the Code or any applicable Similar Laws, as described above.

S-59

UNDERWRITING

Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, UBS Securities LLC, Wells Fargo Securities, LLC and RBC Capital Markets, LLC are acting as joint book-running managers of the offering and as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the number of Series B Preferred units set forth opposite the underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the Series B Preferred units included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the Series B Preferred units (other than those covered by the over-allotment option described below) if they purchase any of the Series B Preferred units.

The Series B Preferred units sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. Any Series B Preferred units sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price less a concession not to exceed $        per unit; provided that the concession will be $        per unit for sales to institutions. The underwriters may allow, and dealers may reallow, a concession not to exceed $        per unit on sales to other dealers. If all the Series B Preferred units are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to                additional Series B Preferred units at the public offering price less the underwriting discount, solely to cover over-allotments. To the extent the option is exercised, each underwriter must purchase a number of additional Series B Preferred units approximately proportionate to that underwriter’s initial purchase commitment. Any Series B Preferred units issued or sold under the option will be issued and sold on the same terms and conditions as the other Series B Preferred units that are the subject of this offering.

We have agreed that, for a period of 30 days from the date of this prospectus supplement, we will not, without the prior written consent of Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, UBS Securities LLC, Wells Fargo Securities, LLC and RBC Capital Markets, LLC, offer, sell, contract to sell, pledge, otherwise dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by us or any affiliate of us or any person in privity with us or any affiliate of us, directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, or announce the offering, of any debt securities issued or guaranteed by us or units of any class of our capital stock (other than the Series B Preferred units) that is preferred as to the payment of distributions, or as to the distribution of assets upon any liquidation or dissolution of us, over units of any other class of our capital stock; provided that we may issue and sell the Series B Preferred units to the underwriters pursuant to the underwriting agreement. Morgan Stanley & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, UBS Securities LLC, Wells Fargo Securities,

S-60

LLC and RBC Capital Markets, LLC in their sole discretion may release any of the securities subject to this lock-up agreement at any time.

We intend to apply to list the Series B Preferred units on the NYSE under the symbol “OAK PR B.” If the application is approved, we expect trading in the Series B Preferred units on the NYSE to begin within 30 days after the Series B Preferred units are first issued.

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering.

The estimated offering expenses payable by us (excluding the underwriting discount) are approximately $1 million, which includes legal, accounting and printing costs and various other fees associated with registering the units.

In connection with the offering, the underwriters may purchase and sell units in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions, and stabilizing purchases. Short sales involve secondary market sales by the underwriters of a greater number of units than they are required to purchase in the offering. Covering transactions involve purchases of Series B Preferred units in the open market after the distribution has been completed to cover short positions. To close a naked short position, the underwriters must purchase Series B Preferred units in the open market after the distribution has been completed. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Series B Preferred units in the open market after pricing that could adversely affect investors who purchase in the offering. To close a covered short position, the underwriters must purchase Series B Preferred units in the open market after the distribution has been completed. Stabilizing transactions involve bids to purchase Series B Preferred units so long as the stabilizing bids do not exceed a specified maximum.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the units. They may also cause the price of the units to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

We expect to deliver the units against payment for the units on or about the date specified in the last paragraph of the cover page of this prospectus supplement, which will be the fifth business day following the date of the pricing of the units (“T+5”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade units on the date of pricing or the next two succeeding business day will be required, by virtue of the fact that the units initially will settle in T+5, to specify alternative settlement arrangements to prevent a failed settlement.

S-61

The underwriters and their respective affiliates have performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses. The underwriters and their respective affiliates may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and instruments of ours or our affiliates. Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Series B Preferred units. Any such short positions could adversely affect future trading prices of the Series B Preferred units. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or financial instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

DESCRIPTION OF UNITS

General

The following is a summary of some of the terms of our units, the material provisions of the Third Amended and Restated Operating Agreement of Oaktree Capital Group, LLC, which provides for the issuance of our units (as amended as of the date of this prospectus, our “operating agreement”), and certain relevant provisions of the Delaware Limited Liability Company Act (the “Act”). The following summary is not complete and is subject to, and qualified in its entirety by reference to, all of the provisions of our operating agreement, a copy of which has been incorporated by reference herein and which you may obtain as described under “Where You Can Find More Information and Incorporation by Reference,” and the Act. As of May 6, 2016, there were 62,619,464 Class A units outstanding, 92,440,656 Class B units outstanding and no preferred units outstanding.

Our operating agreement authorizes our board of directors to issue an unlimited number of additional units and options, rights, warrants and appreciation rights relating to such units for consideration or for no consideration and on the terms and conditions established by our board of directors in its sole discretion without the approval of any Class A unitholders. These additional securities may be used for a variety of purposes, including future offerings to raise additional capital, acquisitions and equity incentive plans. Our operating agreement currently designates the terms of Class A units and Class B units.

Class A Units

All of our outstanding Class A units are duly issued. Upon payment in full of the consideration payable upon original issuance with respect to our Class A units, as determined by our board of directors, the holders of such units will not be liable to us to make any additional capital contributions with respect to such units (except as otherwise required by Sections 18-607 and 18-804 of the Act). No holder of our Class A units is entitled to preemptive, redemption or conversion rights.

Voting Rights

Holders of Class A units are entitled to one vote per unit held of record on all matters submitted to a vote of our unitholders. Generally, all matters to be voted on by our unitholders must be approved by a majority (or, in the case of election of directors when the Oaktree control condition (as defined below under “Our Operating Agreement — Duties of Officers, Directors and Manager”) is no longer satisfied, by a plurality) of the votes entitled to be cast by all Class A units and Class B units present in person or represented by proxy at a meeting of unitholders, voting together as a single class.

Distribution Rights

Holders of Class A units share ratably (based on the number of units held) in any distribution authorized by our board of directors out of funds legally available therefor, subject to any statutory or contractual restrictions or limitations on distributions or as otherwise determined by our board of directors and to any restrictions on distributions imposed by the terms of any outstanding preferred units.

Liquidation Rights

Upon our dissolution, liquidation or winding up, after payment in full of all amounts required to be paid to creditors and to the holders of preferred units having liquidation preferences, if any, the holders of our Class A units and any other equity securities we may subsequently issue that are pari passu with our Class A units will be entitled to receive our remaining assets available for distribution in proportion to the Class A units and other equity securities held by them as of a record date determined by the liquidator.

6

Other Matters

Under our operating agreement, in the event that our board of directors determines that we should seek relief pursuant to Section 7704(e) of the Code (as defined below), to preserve our status as a partnership for U.S. federal (and applicable state) income tax purposes, we and each of our unitholders will be required to agree to adjustments required by the tax authorities, and we will pay such amounts as required by the tax authorities to preserve our status as a partnership.

Class B Units

All of our Class B units have been duly issued and are held by OCGH, which is controlled by our senior executives. No holder of Class B units is entitled to preemptive, redemption or conversion rights.

Voting Rights

Holders of our Class B units are entitled to ten votes per unit held of record on all matters submitted to a vote of our unitholders. However, in the event that the Oaktree control condition is no longer satisfied, our Class B units will be entitled to only one vote per unit. Generally, all matters to be voted on by our unitholders must be approved by a majority (or, in the case of election of directors when the Oaktree control condition is no longer satisfied, a plurality) of the votes entitled to be cast by all Class A units and Class B units present in person or represented by proxy at a meeting of unitholders, voting together as a single class.

Distribution Rights

Holders of our Class B units do not have any right to receive distributions other than distributions consisting of Class B units paid proportionally with respect to each outstanding Class B unit.

Liquidation Rights

Upon our liquidation, dissolution or winding up, no holder of Class B units has any right to receive distributions in respect of its Class B units.

Preferred Units

Our operating agreement authorizes our board of directors to establish one or more series of preferred units. Unless required by law or by any securities exchange on which our units are listed for trading, the authorized preferred units will be available for issuance without further action by Class A unitholders. Our board of directors is able to determine, with respect to any series of preferred units, the terms and rights of that series, including:

7

We could issue a series of preferred units that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of Class A units might believe to be in their best interests or in which holders of Class A units might receive a premium for their Class A units over the market price of the Class A units.

Class Structure

Our Class B units have ten votes per unit, while our Class A units have one vote per unit. All of our Class B units, representing 94% of the voting power of our outstanding membership interests as of May 6, 2016, are controlled indirectly by our senior executives through their control of OCGH. Because of our dual-class structure, as long as the Oaktree control condition is satisfied, our senior executives are able to control all matters submitted to our unitholders for approval even if OCGH owns significantly less than 50% of our outstanding units. This concentrated control could discourage others from initiating any potential merger, takeover or other change of control transaction that other unitholders may view as beneficial.

Listing and Trading

Our Class A units are listed on the New York Stock Exchange under the trading symbol “OAK.”

Transfer Agent and Registrar

The transfer agent and registrar for our Class A units is American Stock Transfer & Trust Company.
