counterparty risk: the risk that the Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund; that the Fund’s counterparty will be unable or unwilling to perform its obligations; that the Fund will be unable to enforce contractual remedies if its counterparty defaults; that if a counterparty (or an affiliate of a counterparty) becomes bankrupt, the Fund may experience significant delays in obtaining any recovery or may obtain limited or no recovery in a bankruptcy or other insolvency proceeding. The Fund has

historically obtained exposure to the Index through swap transactions with a limited number of counterparties and will likely enter into swap transactions related to the Index with a limited number of counterparties for the foreseeable future. To the extent that the Fund enters into multiple transactions with a small set of counterparties, it will be subject to increased counterparty risk.

defaulted securities risk: the significant risk of the uncertainty of repayment of defaulted securities (e.g., a security on which a principal or interest payment is not made when due) and obligations of distressed issuers (including insolvent issuers or issuers in payment or covenant default, in workout or restructuring or in bankruptcy or similar proceedings). Such investments entail high risk and have speculative characteristics.

financial services risk: the risk that an investment in issuers in the financial services sector or transactions with one or more counterparties in the financial services sector may be adversely affected by, among other things: (i) changes in governmental regulation, which may limit both the amounts and the types of loans and other financial commitments financial services companies can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain; (ii) fluctuations, including as a result of interest rate changes or increased competition, in the availability and cost of capital funds on which the profitability of financial services companies is largely dependent; (iii) deterioration of the credit markets; (iv) credit losses resulting from financial difficulties of borrowers, especially when financial services companies are exposed to non-diversified or concentrated loan portfolios; (v) financial losses associated with investment activities, especially when financial services companies are exposed to financial leverage; (vi) the risk that any financial services company experiences substantial declines in the valuations of its assets, takes action to raise capital, or ceases operations; (vii) the risk that a market shock or other unexpected market, economic, political, regulatory, or other event might lead to a sudden decline in the values of most or all companies in the financial services sector; (viii) events leading to limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, leading to market-wide liquidity problems; and (ix) the interconnectedness or interdependence among financial services companies, including the risk that the financial distress or failure of one financial services company may materially and adversely affect a number of other financial services companies.

foreign investing risk: the risk that investments in foreign securities or in issuers with significant exposure to foreign markets, as compared to investments in U.S. securities or in issuers with predominantly domestic market exposure, may be more vulnerable to economic, political, and social instability and subject to less government supervision, less protective custody practices, lack of transparency, inadequate regulatory and accounting standards, delayed or infrequent settlement of transactions, and non-U.S. taxes. If the Fund buys securities denominated in a foreign currency, receives income in foreign currencies, or holds foreign currencies from time to time, the value of the Fund’s assets, as measured in U.S. dollars, can be affected unfavorably by changes in exchange rates relative to the U.S. dollar or other foreign currencies. Foreign markets are also subject to the risk that a foreign government could restrict foreign exchange transactions or otherwise implement unfavorable currency regulations. In addition, foreign securities may be subject to currency exchange rates or regulations, the imposition of economic sanctions, tariffs or other government restrictions, higher transaction and other costs, reduced liquidity, and delays in settlement.

investment company and exchange-traded fund risk: the risk that an investment company or other pooled investment vehicle, including any ETFs or money market funds, in which the Fund invests will not achieve its investment objective or execute its investment strategies effectively or that significant purchase or redemption activity by shareholders of such an investment company might negatively affect the value of its shares. The Fund must pay its pro rata portion of an investment company’s fees and expenses. To the extent the Adviser determines to invest Fund assets in other investment companies, the Adviser will have an incentive to invest in other DoubleLine funds over investment companies sponsored or managed by others and to maintain such investments once made due to its own financial interest in those products and other business considerations.

liquidity risk: the risk that the Fund may be unable to sell a portfolio investment at a desirable time or at the value the Fund has placed on the investment. Illiquidity may be the result of, for example, low trading volume, lack of a market maker, or contractual or legal restrictions that limit or prevent the Fund from selling securities or closing derivative positions. During periods of substantial market disruption, a large portion of the Fund’s assets could potentially experience significant levels of illiquidity. The values of illiquid investments are often more volatile than the values of more liquid investments. It may be more difficult for the Fund to determine a fair value of an illiquid investment than that of a more liquid comparable investment.

operational and information security risks: an investment in the Fund, like any fund, can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The rapid development and increasingly widespread use of artificial intelligence in the financial services industry, including machine learning technology and generative artificial intelligence such as ChatGPT, could exacerbate these risks. The occurrence of any of these failures, errors or breaches could result in investment losses to the Fund, a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

structured products and structured notes risk: the risk that an investment in a structured product, which includes, among other things, CDOs, mortgage-backed securities, other types of asset-backed securities and certain types of structured notes, may decline in value due to changes in the underlying instruments, indexes, interest rates or other factors on which the product is based (“reference measure”). Depending on the reference measure used and the use of multipliers or deflators (if any), changes in interest rates and movement of the reference measure may cause significant price and cash flow fluctuations. Application of a multiplier is comparable to the use of financial leverage, a speculative technique. Holders of structured products indirectly bear risks associated with the reference measure, are subject to counterparty risk and typically do not have direct rights against the reference measure. Structured products are generally privately offered and sold, and thus, are not registered under the securities laws and may be thinly traded or have a limited trading market and may have the effect of increasing the Fund’s illiquidity, reducing the Fund’s income and the value of the investment. At a particular point in time, the Fund may be unable to find qualified buyers for these securities. Investments in structured notes involve risks including interest rate risk, credit risk and market risk.

asset-backed securities investment risk: the risk that borrowers may default on the obligations that underlie the asset-backed security and that, during periods of falling interest rates, asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate, and the risk that the impairment of the value of the collateral underlying a security in which the Fund invests (due, for example, to non-payment of loans) will result in a reduction in the value of the security.

loan risk: the risk that (i) if the Fund holds a loan through another financial intermediary, or relies on a financial intermediary to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial intermediary; (ii) any collateral securing a loan may be insufficient or unavailable to the Fund, because, for example, the value of the collateral securing a loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate, and the Fund’s rights to collateral may be limited by bankruptcy or insolvency laws; (iii) investments in highly leveraged loans or loans of stressed, distressed, or defaulted issuers may be subject to significant credit and liquidity risk; (iv) a bankruptcy or other court proceeding could delay or limit the ability of the Fund to collect the principal and interest payments on that borrower’s loans or adversely affect the Fund’s rights in collateral relating to a loan; (v) there may be limited public information available regarding the loan and the relevant borrower(s); (vi) the use of a particular interest rate benchmark may limit the Fund’s ability to achieve a net return to shareholders that consistently approximates the average published Prime Rate of U.S. banks; (vii) the prices of certain floating rate loans that include a feature that prevents their interest rates from adjusting if market interest rates are below a specified minimum level may appreciate less than other instruments in response to changes in interest rates should interest rates rise but remain below the applicable minimum level; (viii) if a borrower fails to comply with various restrictive covenants that may be found in loan agreements, the borrower may default in payment of the loan; (ix) if the Fund invests in loans

that contain fewer or less restrictive constraints on the borrower than certain other types of loans (“covenant-lite” loans), it may have fewer rights against the borrowers of such loans, including fewer protections against the possibility of default and fewer remedies in the event of default; (x) the loan is unsecured; (xi) there is a limited secondary market; (xii) transactions in loans may settle on a delayed basis, and the Fund may not receive the proceeds from the sale of a loan for a substantial period of time after the sale, which may result in sale proceeds related to the sale of loans not being available to make additional investments or to meet the Fund’s redemption obligations until potentially a substantial period after the sale of the loans; and (xiii) loans may be difficult to value and may be illiquid, which may adversely affect an investment in the Fund. The Fund may invest in loans directly or indirectly by investing in shares of another investment company and in either case will be subject to the risks described above.

real estate sector risk: the risk that real estate-related investments may decline in value as a result of factors affecting the real estate sector, such as the supply of real property in certain markets, changes in zoning laws, delays in completion of construction, changes in real estate values, changes in property taxes, levels of occupancy, and local, regional, and general market conditions. Along with the risks common to different types of real estate-related investments, REITs, no matter the type, involve additional risk factors, including poor performance by the REIT’s manager, adverse changes to the tax laws, and the possible failure by the REIT to qualify for the favorable tax treatment available to REITs under the Internal Revenue Code of 1986, as amended, or the exemption from registration under the Investment Company Act of 1940, as amended. REITs are not diversified and are heavily dependent on cash flow earned on the property interests they hold.

derivatives risk: the risk that an investment in derivatives will not perform as anticipated by an Adviser, may not be available at the time or price desired, cannot be closed out at a favorable time or price, will increase the Fund’s transaction costs, or will increase the Fund’s volatility; that derivatives may create investment leverage; that, when a derivative is used as a substitute for or alternative to a direct cash investment, the transaction may not provide a return that corresponds precisely or at all with that of the cash investment; that the positions may be improperly executed or constructed; that the Fund’s counterparty will be unable or unwilling to perform its obligations; or that, when used for hedging purposes, derivatives will not provide the anticipated protection, causing the Fund to lose money on both the derivatives transaction and the exposure the Fund sought to hedge.

index risk: the risk that the Fund’s investments in derivatives based on the Index or that use the Index as the reference asset, or other substitute investment exposure to the Index, may underperform the return of the Index for a number of reasons, including, for example, (i) the performance of derivatives related to the Index may not correlate with the Index and/or may underperform the Index due to transaction costs, fees, or other aspects of the transaction’s pricing; (ii) the Fund may not be able to find counterparties willing to enter into derivative instruments whose returns are based on the return of the Index or find parties who are willing to do so at an acceptable cost or level of risk to the Fund; and (iii) errors may arise in carrying out the Index’s methodology, or the Index provider may incorrectly report information concerning the Index. Although the Adviser has licensed from the Index’s sponsor the right to use the Index as part of implementing the

Fund’s principal investment strategies, there can be no guarantee that the Index will be maintained indefinitely or that the Fund will be able to continue to utilize the Index to implement the Fund’s principal investment strategies indefinitely. If the sponsor of the Index ceases to maintain the Index, the Fund no longer has the ability to utilize the Index to implement its principal investment strategies, or other circumstances exist that the Adviser or the Fund’s Board of Trustees concludes substantially limit the Fund’s ability to create cost-effective synthetic investment exposure to the Index, the Adviser or the Fund’s Board of Trustees may substitute the Index with another index that it chooses in its sole discretion and without advance notice to shareholders. There can be no assurance that any substitute index so selected will be similar to the Index or will perform in a manner similar to the Index. Unavailability of the Index could affect adversely the ability of the Fund to achieve its investment objective.

market capitalization risk: the risk that investing substantially in issuers in one market capitalization category (large, medium or small) may adversely affect the Fund because of unfavorable market conditions particular to that category of issuers, such as larger, more established companies being unable to respond quickly to new competitive challenges or attain the high growth rates of successful smaller companies, or, conversely, stocks of smaller companies being more volatile than those of larger companies due to, among other things, narrower product lines, more limited financial resources, fewer experienced managers and there typically being less publicly available information about small capitalization companies.

portfolio turnover risk: the risk that frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in larger distributions of taxable capital gains to investors as compared to a fund that trades less frequently.

equity issuer risk: the risk that the market price of common stocks and other equity securities may go up or down, sometimes rapidly or unpredictably, including due to factors affecting equity securities markets generally, particular industries represented in those markets, or the issuer itself.
