Fee Waiver and/or Expense Reimbursement⁴

Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement⁴

The Fund enters into index-related swap transactions, under which the Fund incurs fees payable to its counterparties and other costs. Those fees and costs reduce the index-based returns to the Fund under the swaps. During the Fund’s most recent fiscal year, those expenses and charges were approximately 0.21% of the Fund’s net assets. None of these fees and costs are reflected in the table above or in the example below. See “Index Risk – Note regarding Index-Based Swaps” for more information regarding such fees and costs.

Other expenses have been restated to reflect current contractual fees.

“Acquired Fund Fees and Expenses” are expenses indirectly incurred by the Fund as a result of its investments in one or more underlying funds, including exchange-traded funds (“ETFs”) and money market funds. Because these costs are indirect, the Total Annual Fund Operating Expenses in this fee table will not correlate to the expense ratio in the Fund’s financial statements, since financial statements only include direct costs of the Fund and not the indirect costs of investing in the underlying funds. The Fund’s Acquired Fund Fees and Expenses have been restated to reflect current expenses.

DoubleLine Alternatives LP (the “Adviser” or “DoubleLine Alternatives”) has contractually agreed to waive its investment advisory fee and to reimburse the Fund for other ordinary operating expenses to the extent necessary to limit ordinary operating expenses to an amount not to exceed 1.10% for Class I shares, 1.17% for Class I2 shares and 1.35% for Class N shares. Ordinary operating expenses exclude taxes, commissions, mark-ups, litigation expenses, indemnification expenses, interest expenses, Acquired Fund Fees and Expenses, and any extraordinary expenses. These expense limitations will apply until at least August 1, 2027, except that they may be terminated by the Board of Trustees at any time. To the extent that the Adviser waives its investment advisory fee and/or reimburses the Fund for other ordinary operating expenses, it may seek reimbursement of a portion or all of such amounts at any time within three

fiscal years after the fiscal year in which such amounts were waived or reimbursed. Any such recoupment may not cause the Fund’s ordinary operating expenses to exceed the expense limitation that was in place when the fees were waived or expenses were reimbursed. Additionally, the Adviser would generally seek recoupment only in accordance with the terms of any expense limitation that is in place at the time of recoupment.

Long Basket or Index-Related Exposure. The Adviser may create one or more long commodity-related positions in the Fund’s portfolio, representing what the Adviser considers from time to time to be efficient, broad-based exposure to a number of commodities. For example, the Adviser may identify one or more baskets or indexes of commodities, which will typically be administered and maintained by a third party, although the Adviser may provide recommendations to the basket or index sponsor during the construction of the basket or index or from time to time thereafter as to the exposures to be reflected in the basket or index. In pursuit of this strategy, the Adviser will normally attempt to replicate within the Fund’s portfolio the commodity exposures of the basket or index. These basket- or index-based exposures will typically comprise at least 50% of the Fund’s commodity exposures, and may constitute as much as 100% of the Fund’s commodity exposures. The Adviser, in its discretion, may add to or replace the baskets or indexes, or may determine to implement the Fund’s investment program without relying on any baskets or indexes. In the latter case, the Adviser would rely principally on the investment techniques described under “Tactical Commodity Exposure,” below.

“MSBFMCI Beta Exposure.” As of the date of this Prospectus, the Adviser has licensed the right to use the Morgan Stanley Backwardation-Focused Multi-Commodity Index (described below) (the “Morgan Stanley Index”), and the Fund invests in derivative instruments intended to provide exposure to the Morgan Stanley Index in implementing this aspect of the Fund’s principal investment strategies. However, the Adviser at any time may discontinue the use of the Morgan Stanley Index or may use other commodities-related indices at any time and without notice or may work with another index sponsor to create a custom commodities-related index. There can be no assurance that the Fund will continue to use the Morgan Stanley Index in implementing its principal investment strategies. For more information regarding the Morgan Stanley Index, see “The Morgan Stanley Index” below.

Tactical Commodity Exposure (also referred to as the “DoubleLine Commodity Long Short Strategy” or “DCLSS Alpha Exposure”). The Adviser may seek to generate additional returns or modify the Fund’s broad-based commodities exposures by taking long and/or short positions in individual commodities or in other baskets of commodities or commodity indexes. These investments may be made in commodities, such as precious metals, that are not represented in the basket or index of commodities through which the Fund may be obtaining broad-based commodities exposures. The Adviser will determine whether to take such positions based on the Adviser’s quantitative models as well as the Adviser’s views of changing market, economic and political factors, market fundamentals, macroeconomic trends, and global or local events. The Adviser may also seek to pursue “market neutral” returns by creating roughly equal “long” and “short” exposures on different commodities of any kind. The Fund’s tactical commodity exposures will be actively managed, and the allocation of the Fund’s assets to various commodities will change over time, sometimes rapidly.

active management risk: the risk that the Fund will fail to meet its investment objective and that the Fund’s investment performance will depend, at least in part, on how its assets are allocated and reallocated among asset classes, sectors, underlying funds and/or investments and that such allocation will focus on asset classes, sectors, underlying funds, and/or investments that perform poorly or underperform other asset classes, sectors, underlying funds, and/or available investments. Any given investment strategy may fail to produce the intended results, and the Fund’s portfolio may underperform other comparable funds because of portfolio management decisions related to, among other things, the selection of investments, portfolio construction, risk assessments, and/or the outlook on market trends and opportunities.

cash position risk: the risk that to the extent that the Fund holds assets in cash, cash equivalents, and other short-term investments, the ability of the Fund to meet its objective may be limited.

commodities risk: the risk that the value of the Fund’s shares may be affected by changes in the values of the Fund’s investment exposures to commodities or commodity-related instruments, which may be extremely volatile and difficult to value. The value of commodities and commodity-related instruments may be affected by, among other factors, market movements, commodity index volatility, changes in interest rates, or factors affecting supply, demand and/or other market fundamentals with respect to a particular sector, industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The Fund will likely at times have significant exposure to particular sectors through its commodities- related investments, including, for example, the energy, industrial metals, and agricultural and livestock sectors and may be exposed to greater risk associated with events affecting those sectors.

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 directly by the Fund or held by special purpose or structured vehicles in which the Fund invests; 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 Morgan Stanley Index through swap transactions with a limited number of counterparties, and will likely enter into swap transactions related to the Morgan Stanley 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.

debt securities risks:

credit risk: the risk that an issuer, counterparty or other obligor to the Fund will fail to pay its obligations to the Fund when they are due, which may reduce the Fund’s income and/or reduce, in whole or in part, the value of the Fund’s investment. Actual or perceived changes in the financial condition of an obligor, changes in economic, social or political conditions that affect a particular type of security, instrument, or obligor, and changes in economic, social or political conditions generally can increase the risk of default by an obligor, which can affect a security’s or other instrument’s credit quality or value and an obligor’s ability to honor its obligations when due. The values of lower-quality debt securities (including debt securities commonly known as “high yield” securities or “junk bonds”), including floating rate loans, tend to be particularly sensitive to these changes. Certain debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics by certain rating agencies. The values of securities or instruments also may decline for a number of other reasons that relate directly to the obligor, such as management performance, financial leverage, and reduced demand for the obligor’s goods and services, as well as the historical and prospective earnings of the obligor and the value of its assets.

extension risk: the risk that if interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply.

interest rate risk: the risk that debt instruments will change in value because of changes in interest rates. The value of an instrument with a longer duration (whether positive or negative) will be more sensitive to changes in interest rates than a similar instrument with a shorter duration. Bonds and other debt instruments typically have a positive duration. The value of a debt instrument with positive duration will generally decline if interest rates increase. Certain other investments, such as inverse floaters and certain derivative instruments, may have a negative duration. The value of instruments with a negative duration will generally decline if interest rates decrease. Inverse floaters, interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments. Inflationary price movements may cause the fixed income securities markets to experience heightened levels of interest rate volatility and liquidity risk. Fiscal, economic, monetary or other government policies or measures have in the past, and may in the future, cause or exacerbate risks associated with interest rates, including changes in interest rates. Further, in market environments where interest rates are rising, issuers may be less willing or able to make principal and interest payments on fixed-income investments when due.

prepayment risk: the risk that the issuer of a debt security, including floating rate loans and mortgage-related securities, repays all or a portion of the principal prior to the security’s maturity. In times of declining interest rates, there is a greater likelihood that the Fund’s higher yielding securities will be pre-paid with the Fund being unable to reinvest the proceeds in an investment with as great a yield. Prepayments can therefore result in lower yields to shareholders of the Fund.

derivatives risk: the risk that an investment in derivatives will not perform as anticipated by the 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.

emerging market country risk: the risk that investing in emerging markets, as compared to foreign developed markets, increases the likelihood that the Fund will lose money, due to more limited information about the issuer and/or the security; higher brokerage costs; different accounting, auditing and financial reporting standards; less developed legal systems and thinner trading markets; the possibility of currency blockages or transfer restrictions; an emerging market country’s dependence on revenue from particular commodities or international aid; and expropriation, nationalization or other adverse political or economic developments.

focused investment risk: the risk that a fund that invests a substantial portion of its assets in a particular market, industry, sector, group of industries or sectors, country, region, group of countries or asset class is, relative to a fund that invests in a more diverse investment portfolio, more susceptible to any single economic, market, political, regulatory or other occurrence. This is because, for example, issuers in a particular market, industry, region, sector or asset class may react similarly to specific economic, market, regulatory, political or other developments. The particular markets, industries, regions, sectors or asset classes in which the Fund may focus its investments may change over time and the Fund may alter its focus at inopportune times.

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.

index risk: the risk that the portion of the Fund invested in instruments based on an index or basket of commodities or that use an index or basket of commodities as the reference asset may not match or may underperform the return of the index or basket for a number of reasons, including, for example, (i) the performance of derivatives related to an index or basket in which the Fund invests may not correlate with the performance of the index or basket and/or may underperform the index or basket 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 basket, or the Fund may be unable to 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 an index’s methodology, or an index provider may incorrectly report information concerning the index. There can be no guarantee that any index, including the Morgan Stanley Index, will be maintained indefinitely or that the Fund will be able to continue to utilize a specific index to implement the Fund’s principal investment strategies indefinitely.

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.

large transactions risk: the risk that certain account holders, including the Adviser or funds or accounts over which the Adviser (or related parties of the Adviser) has investment discretion, may from time to time own or control a significant percentage of the Fund’s shares. The Fund is subject to the risk that a redemption by those shareholders of all or a portion of their Fund shares, including as a result of an asset allocation decision made by the Adviser (or related parties of the Adviser), will adversely affect the Fund’s performance if it is forced to sell portfolio securities or invest cash when the Adviser would not otherwise choose to do so. In addition, a large number of shareholders collectively may purchase or sell Fund shares in large amounts rapidly or unexpectedly. Redemptions of a large number of shares may affect the liquidity of the Fund’s portfolio, increase the Fund’s transaction costs, and accelerate the realization of taxable income and/or gains to shareholders.

leveraging risk: the risk that certain investments by the Fund involving leverage may have the effect of increasing the volatility of the value of the Fund’s portfolio, and the risk of loss in excess of invested capital.

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.

market risk: the risk that markets will perform poorly or that the returns from the securities in which the Fund invests will underperform returns from the general securities markets or other types of investments. Markets may, in response to governmental actions or intervention or general market conditions, including real or perceived adverse political, economic or market conditions, tariffs and trade disruptions, armed conflicts and/or wars, inflation, recession, changes in interest or currency rates, lack of liquidity in the bond markets or adverse investor sentiment, or other external factors, experience periods of high volatility and reduced liquidity. During those periods, the Fund may experience high levels of shareholder redemptions, and may have to sell securities at times when the Fund would otherwise not do so, and potentially at unfavorable prices. Certain securities may be difficult to value during such periods. Market risk involves the risk that the value of the Fund’s investment portfolio will change, potentially frequently and in large amounts, as the prices of its investments go up or down. During periods of severe market stress, it is possible that the market for some or all of the Fund’s investments may become highly illiquid. Inflationary price movements may cause the fixed income securities markets to experience heightened levels of interest rate volatility and liquidity risk. Please see “debt securities risks – interest rate risk” herein for more information.

models and data risk: the risk that the quantitative models or related data used in managing the Fund fail to identify profitable opportunities. In addition, failures to properly gather, organize, and analyze large amounts of data or errors in a model or data, or in the application of such models, may result in, among other things, execution and investment allocation failures and investment losses. For example, the models may incorrectly identify opportunities or data used in the construction and application of models may prove to be inaccurate or stale, which may result in misidentified opportunities that may lead to substantial losses for the Fund. A given model may be more effective with certain instruments or strategies than others, and there can be no assurance that any model can identify and incorporate all factors that will affect an investment’s price or performance.

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.

securities or sector selection risk: the risk that the securities held by the Fund will underperform securities held in other funds investing in similar asset classes or comparable benchmarks because of the portfolio managers’ choice of securities or sectors for investment. To the extent the Fund allocates a higher percentage of its investment portfolio to a particular sector or related sectors, the Fund will be more susceptible to events or factors affecting companies in that sector or related sectors. For example, the values of securities of companies in the same or related sectors may be negatively affected by the common characteristics they share, the common business risks to which they are subject, common regulatory burdens, or regulatory changes that affect them similarly. Such characteristics, risks, burdens or changes include, but are not limited to, changes in governmental regulation, inflation or deflation, rising or falling interest rates, competition from new entrants, and other economic, market, political or other developments specific to that sector or related sectors.

short position risk: the risk that an increase in the value of an instrument, index or interest rate with respect to which the Fund has established a short position will result in a loss to the Fund.

structured products and structured notes risk: the risk that an investment in a structured product, which includes, among other things, collateralized debt obligations, 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.

tax risk: in order to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended, the Fund must meet requirements regarding, among other things, the source of its income. Certain investments in commodity-linked derivatives do not give rise to qualifying income for this purpose, and it is possible that certain investments in other commodity-linked instruments, ETFs and other investment pools will not give rise to qualifying income. Any income the Fund derives from investments in instruments that do not generate qualifying income must be limited to a maximum of 10% of the Fund’s annual gross income. If the Fund were to earn non-qualifying income in excess of 10% of its annual gross income, it could fail to qualify as a regulated investment company for that year. If the Fund were to fail to qualify as a regulated investment company, the Fund would be subject to tax and shareholders of the Fund would be subject to the risk of diminished returns.

U.S. Government securities risk: the risk that debt securities issued or guaranteed by certain U.S. Government agencies, instrumentalities, and sponsored enterprises are not supported by the full faith and credit of the U.S. Government, and so investments in their securities or obligations issued by them involve credit risk greater than investments in other types of U.S. Government securities.

valuation risk: the risk that the Fund will not value its investments in a manner that reflects their market values or that the Fund will not be able to sell any investment at a price equal to the valuation ascribed to that investment for purposes of calculating the Fund’s net asset value (“NAV”). The valuation of the Fund’s investments involves subjective judgment. Certain securities in which the Fund may invest may be more difficult to value, especially during periods of market disruptions or extreme market volatility. Valuations that do not reflect the market value that will be realized upon the disposition of the Fund’s portfolio holdings could result in the Fund’s shareholder transactions being effected at an NAV that does not accurately reflect the underlying value of the Fund’s portfolio, resulting in the dilution of shareholder interests.

Class I2 shares of the Fund were not available for purchase until November 3, 2025. Performance shown prior to that inception date is that of Class I shares (which invest in the same portfolio of securities as Class I2 shares), reduced by an estimate of the additional operating expenses that would have applied to Class I2 shares prior to November 3, 2025. The actual additional expenses incurred had Class I2 shares begun operations earlier may have been greater or less than that estimate.
