FORWARD-LOOKING STATEMENTS
This quarterly report contains forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended (the Securities Act), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the Exchange Act), which reflect our current views with respect to, among other things, our future results of operations and financial performance. In some cases, you can identify forward-looking statements by words such as anticipate, approximately, believe, continue, could, estimate, expect, intend, may, outlook, plan, potential, predict, seek, should, will and would or the negative version of these words or other comparable or similar words. These statements identify prospective information. Important factors could cause actual results to differ, possibly materially, from those indicated in these statements. Forward-looking statements are based on our beliefs, assumptions and expectations of our future performance, taking into account all information currently available to us. Such forward-looking statements are subject to risks and uncertainties and assumptions relating to our operations, financial results, financial condition, business prospects, growth strategy and liquidity.
In addition to factors previously disclosed in Brookfield Asset Management Inc.’s (“Brookfield”) and Oaktree Capital Group, LLC’s (“OCG”) reports filed with securities regulators in Canada and the United States and those identified elsewhere in this quarterly report, the following factors, among others, could cause actual results to differ materially from forward-looking statements and information or historical performance: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of Brookfield and OCG to terminate the definitive merger agreement between Brookfield and OCG; the outcome of any legal proceedings that may be instituted against Brookfield, OCG or their respective unitholders, shareholders or directors; the ability to obtain regulatory approvals and meet other closing conditions to the merger, including the risk that regulatory approvals required for the merger are not obtained or are obtained subject to conditions that are not anticipated or that are material and adverse to Brookfield’s or OCG’s business; a delay in closing the merger; business disruptions from the proposed merger that will harm Brookfield’s or OCG’s business, including current plans and operations; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the merger; certain restrictions during the pendency of the merger that may impact Brookfield’s or OCG’s ability to pursue certain business opportunities or strategic transactions; the ability of Brookfield or OCG to retain and hire key personnel; uncertainty as to the long-term value of the Class A shares of Brookfield following the merger; the continued availability of capital and financing following the merger; the business, economic and political conditions in the markets in which Brookfield and OCG operate; changes in OCG’s or Brookfield’s anticipated revenue and income, which are inherently volatile; changes in the value of OCG’s or Brookfield’s investments; the pace of OCG’s or Brookfield’s raising of new funds; changes in assets under management; the timing and receipt of, and impact of taxes on, carried interest; distributions from and liquidation of OCG’s existing funds; the amount and timing of distributions on OCG’s preferred units and Class A units; changes in OCG’s operating or other expenses; the degree to which OCG or Brookfield encounters competition; and general political, economic and market conditions.
Any forward-looking statements and information speak only as of the date of this quarterly report or as of the date they were made, and except as required by law, neither Brookfield nor OCG undertakes any obligation to update forward-looking statements and information. For a more detailed discussion of these factors, also see the information under the captions “Cautionary Information Regarding Forward-Looking Statements” and “Risk Factors” in the consent solicitation statement/prospectus that forms part of the Registration Statement on Form F-4 (No. 333-231335) filed with the SEC by Brookfield in connection with the proposed merger, and the captions “Business Environment and Risks” in Brookfield’s most recent report on Form 40-F for the year ended December 31, 2018, and under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in OCG’s most recent report on Form 10-K for the year ended December 31, 2018, and in each case any material updates to these factors contained in any of Brookfield’s or OCG’s future filings.
As for the forward-looking statements and information that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material. Given these uncertainties, you should not place any reliance on these forward-looking statements and information.
This quarterly report and its contents do not constitute and should not be construed as (a) a recommendation to buy, (b) an offer to buy or solicitation of an offer to buy, (c) an offer to sell or (d) advice in relation to, any securities of OCG or securities of any Oaktree investment fund.



Important Additional Information and Where to Find It
In connection with the proposed mergers, Brookfield filed with the SEC a Registration Statement on Form F-4 (No. 333-231335) that includes a consent solicitation statement of OCG and a prospectus of Brookfield, as well as other relevant documents regarding the proposed transactions. The Registration Statement, as amended, was declared effective by the SEC on June 20, 2019. OCG commenced mailing the definitive consent solicitation statement/prospectus to OCG common unitholders on or about June 24, 2019. This quarterly report does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction.
INVESTORS ARE URGED TO READ THE REGISTRATION STATEMENT AND THE CONSENT SOLICITATION STATEMENT/PROSPECTUS REGARDING THE MERGERS AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC, AS WELL AS ANY AMENDMENTS OR SUPPLEMENTS TO THOSE DOCUMENTS, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.

“assets under management,” or “AUM,” generally refers to the assets we manage and equals the NAV (as defined below) of the assets we manage, the leverage on which management fees are charged, the undrawn capital that we are entitled to call from investors in our funds pursuant to their capital commitments, and our pro-rata portion of AUM managed by DoubleLine (as defined below) in which we hold a minority ownership interest. For our collateralized loan obligation vehicles (“CLOs”), AUM represents the aggregate par value of collateral assets and principal cash, for our publicly-traded BDCs, gross assets (including assets acquired with leverage), net of cash, and for DoubleLine funds, NAV. Our AUM amounts include AUM for which we charge no management fees. Our definition of AUM is not based on any definition contained in our operating agreement or the agreements governing the funds that we manage. Our calculation of AUM and the two AUM-related metrics described below may not be directly comparable to the AUM metrics of other investment managers.
“management fee-generating assets under management,” or “management fee-generating AUM,” is a forward-looking metric and generally reflects the beginning AUM on which we will earn management fees in the following quarter, as more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Measures—Assets Under Management—Management Fee-generating Assets Under Management.”
“incentive-creating assets under management,” or “incentive-creating AUM,” refers to the AUM that may eventually produce incentive income, as more fully described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Measures—Assets Under Management—Incentive-creating Assets Under Management.”
“Class A units” refer to the common units of OCG designated as Class A units.
“common units” or “common unitholders” refer to the Class A common units of OCG or Class A common unitholders, respectively, unless otherwise specified.

“initial public offering” refers to the listing of our Class A units on the New York Stock Exchange on April 12, 2012 whereby Oaktree sold 7,888,864 Class A units and selling unitholders sold 954,159 Class A units.
“Intermediate Holding Companies” collectively refers to the subsidiaries wholly owned by us.
“net asset value,” or “NAV,” refers to the value of all the assets of a fund (including cash and accrued interest and dividends) less all liabilities of the fund (including accrued expenses and any reserves established by us, in our discretion, for contingent liabilities) without reduction for accrued incentives (fund level) because they are reflected in the partners capital of the fund.  
“preferred units” or “preferred unitholders” refer to the Series A and Series B preferred units of OCG or Series A and Series B preferred unitholders, respectively, unless otherwise specified.



“Relevant Benchmark” refers, with respect to:

our non-U.S. Convertible Securities strategy, to an Oaktree custom non-U.S. convertible index that represents the JACI Global ex-U.S. (Local) Index from inception through December 31, 2014 and the Thomson Reuters Global Focus ex-U.S. (USD hedged) Index thereafter;
our High Income Convertible Securities strategy, to the FTSE US High-Yield Market Index; and
our Emerging Markets Equities strategy, to the Morgan Stanley Capital International Emerging Markets Index (Net).
“senior executives” refers collectively to Howard S. Marks, Bruce A. Karsh, Jay S. Wintrob, John B. Frank and Sheldon M. Stone.
“Sharpe Ratio” refers to a metric used to calculate risk-adjusted return. The Sharpe Ratio is the ratio of excess return to volatility, with excess return defined as the return above that of a riskless asset (based on the three-month U.S. Treasury bill, or for our European Senior Loan strategy, the Euro Overnight Index Average) divided by the standard deviation of such return. A higher Sharpe Ratio indicates a return that is higher than would be expected for the level of risk compared to the risk-free rate.
