Financial Markets Highlights (Unaudited) March 31, 2020

· Emerging Markets (EM) Debt

For the 6-month period ended March 31, 2020, U.S. Dollar (USD)-denominated EM fixed income sovereign and corporate bonds indices, represented by the J.P. Morgan Emerging Markets Bond Index (EMBI) Global Diversified and the J.P. Morgan Corporate Emerging Markets Bond Index (CEMBI) Broad Diversified, respectively, posted significant negative returns. Spreads were broadly tighter in the fourth quarter of 2019 and January 2020, but widened significantly in late February and the first three weeks of March as global markets, including EM, felt the impact of an economic shutdown due to the governmental and market reaction to the spread of COVID-19. While all the regions across both indices posted negative returns over the period, Europe and Asia had the least negative returns in the sovereign index, while Asia and the Middle East outperformed regional peers in the corporate index, as measured by the EMBI and CEMBI. Africa was the worst performing region for both the sovereign and corporate indices. For the period, EM Investment Grade (IG) credits significantly outperformed their High Yield (HY) counterparts in both the EMBI and CEMBI.

· Agency Mortgage-Backed Securities (Agency MBS)

For the 6-month period ended March 31, 2020, the Bloomberg Barclays U.S. MBS Index returned 3.55%, outperforming both the Bloomberg Barclays U.S. Government/Credit Bond Index and the Bloomberg Barclays U.S. Corporate Index. Risk-free rates declined during this reporting period, with 5-year, 10-year, and 30-year U.S. Treasury (UST) yields down 116 basis points (bps), 100 bps, and 79 bps, respectively. In response to the sharp decline in economic activity arising out of the governmental and market reaction to COVID-19 toward the end of the period, the Federal Reserve (the Fed) announced and implemented a Quantitative Easing program which included purchasing Agency MBS in an effort to support smooth market functioning and effective transmission of monetary policy. The Fed’s gross Agency MBS purchases totaled $295 billion as of March 31, 2020. While purchases consisted of TBA-eligible pools, primarily current coupon production, they did not include Agency collateralized mortgage obligations (“CMOs”). Over the period, prepayments remained elevated as the 30-year mortgage rate generally decreased and reached a historical low. The 30-year mortgage rate (based on Freddie Mac U.S. 30-year Commitment Rates) decreased by 14 bps and reached a historical low value of 3.29% in March. Consistent with these factors, overall refinancing activity, as measured by the Mortgage Bankers Association (MBA) Refinance Index Seasonally-Adjusted, increased by over 200% and reached high levels last observed in 2009. Overall purchasing activity experienced a steep decline at the end of the period as well. The duration of the Bloomberg Barclays U.S. MBS Index over the period contracted from 2.73 to 1.67 as interest rates declined.

· Non-Agency Mortgage-Backed Securities (Non-Agency MBS)

For the 6-month period ended March 31, 2020, spreads were significantly wider for Non-Agency MBS. The market was digesting potential outcomes including the probability of many homeowners struggling to make payments and potential forbearance scenarios. Net issuance reached approximately $60 billion over the period, outpacing the same period one year ago of $42 billion. Issuance largely consisted of: Non-performing loans/Re-performing loans, Prime Jumbo, Credit Risk Transfers, and Non-Qualified Mortgages. Refinancing activity remained elevated during the period. Given the material credit spread widening and general market volatility in March 2020, we believe that new issuance across the sector will be muted for the foreseeable future. We believe mortgage servicers are the focal point during this time as borrowers pursue forbearance. Servicers must advance principal and interest payments under particular circumstances but servicers may not have the capital to do so for a prolonged period of time. Any expansion in the Term Asset-Backed Securities Loan Facility (TALF) program by the Fed to include Non-Agency MBS would be a relief for this market. Any support for mortgage servicers directly would also be supportive and perhaps stymie further deleveraging from Real Estate Investment Trusts (REITs) receiving margin calls based upon this bearish premise.

· Commercial Mortgage-Backed Securities (CMBS)

For the 6-month period ended March 31, 2020, new issue CMBS spreads were wider alongside broader spreads in credit and equity indices and a sharp decline in interest rates, as a result of market volatility associated with the governmental and market reaction to COVID-19. New issuance of $66.9 billion in CMBS priced during the period, as compared to $41.9 billion from October 2018 through March 2019. As a result of the year end volatility experienced in December 2018, issuers generally made a concerted effort to market as many deals during the first half of the fourth quarter of 2019. Although 2020 got off to a record start with $11.9 billion pricing in January 2020, there was a material slowdown in new issuance in March. For the period, spreads on 10-year AAA last cash flows (LCFs) and BBB- bonds widened materially, especially over a span of the last two weeks. This was largely liquidity driven as fund redemptions and levered CMBS investors created a liquidity vacuum for CMBS bonds as supply flooded the secondary market with limited dealer support. The Trepp CMBS Delinquency Rate for U.S. Commercial Real Estate (CRE) loans had fallen in 20 of the last 26 months as of

Semi-Annual Report March 31, 2020 5

period end, and was at 2.07%, 44 bps lower than it was at the start of the reporting period. However, we would note that this is backwards looking and we would presume the delinquency rate will increase. The Bloomberg Barclays U.S. CMBS ERISA Eligible Total Return Index returned 0.85% during the period, underperforming the broader Bloomberg Barclays U.S. Aggregate Bond Index return of 3.33%. The Moody’s/RCA Commercial Property Price Index (CPPI) increased by 2.95% on the national level for the period ended February 29, 2020, as compared to 3.51% over the prior reporting period.

· U.S. High Yield (U.S. HY)

For the 6-month period ended March 31, 2020, the Bloomberg Barclays U.S. Corporate High Yield Index returned -10.40%. Intermediate-maturity bonds returned -10.40%, underperforming long maturity bonds, which returned -9.78%. Higher-rated bonds outpaced those with lower ratings, as BB-rated bonds returned -7.95%, single-B bonds returned -10.70%, and CCC-rated bonds returned -17.58%. For the period, notable outperformers by industry were Wireless, Pharmaceuticals, and Apartment REITs. Notable underperformers over the period were Oil Field Services, Independent Energy, and Retail REITs.

· Bank Loans

For the 12-month period ended September 30, 2019, the S&P/LSTA Leveraged Loan Index For the 6-month period ended March 31, 2020, the S&P/LSTA Leveraged Loan Index returned -11.54%, with the sharp decline driven entirely by the -12.37% return in March. Consistent with the negative returns, higher quality credits outperformed lower quality credits. BB-rated loans returned -9.64%, ahead of B-rated loans (-11.89%) and CCC-rated loans (-21.78%). The weighted average bid price of the Index ended March at 82.85, down 14% from the end of September 2019. The trailing 12-month default rate, by issuer count, remains low but was up modestly from 1.58% in September 2019 to 2.02% in March 2020, as reported by the Leveraged Commentary & Data (LCD) team at S&P Capital IQ.

· Collateralized Loan Obligations (CLOs)

For the 6-month period ended March 31, 2020, the CLO market saw $45.67 billion in new issuance. October was the busiest month in the period, contributing $10.43 billion of the total. Although refinancing and reset activity was muted on average, it increased substantially in February. Of the 6-month period’s $31.89 billion in refinancing & reset volume, 61% came to market in February as CLO managers tried to capitalize on tight pricing levels. While spreads remained flat to slightly tighter from the start of October through February month-end, they widened significantly in March as the market reacted to broader economic concerns surrounding COVID-19. Spreads up and down the capital stack ended March at levels nearly double where they began the period, resulting in a -6.95% total return according to the J.P. Morgan CLO Total Return Level Index. Secondary trading volumes were modest, but surged in March as managers looked to source liquidity and buying opportunities given the lull in new issuance. CLO fundamentals, while mixed over the period, ended in a weakened state. Market value metrics deteriorated given the loan sell-off in mid-March, while corporate rating downgrades and distressed rates crept higher. The final week of the period saw signs of some stabilization with the intervention of the Fed as loan prices rallied and spreads tightened from recent wides.

Management’s Discussion of Fund Performance (Unaudited) March 31, 2020

For the 6-month period ended March 31, 2020, the DoubleLine Income Solutions Fund underperformed the Bloomberg Barclays Global Aggregate Bond Index return of 0.16%. By the end of the period, market risks related to the governmental and market reaction to the COVID-19 pandemic had by far the largest impact on financial markets, causing the Fed to cut interest rates 150 bps in March 2020 and launch their fourth installment of Quantitative Easing. The primary driver of underperformance over this period was asset allocation. The Index maintains a more than 50% allocation to high quality government debt while the Fund primarily invests in below investment grade debt from both EM and domestic issuers. March 2020 featured a historic flight-to-quality in financial markets, causing significant selling pressure on the various credit sectors within the Fund and sending most sector-level returns into negative territory on a 6-month basis. Agency MBS generated positive total returns due to its longer duration in a falling interest rate environment and contributed positively to performance for the period, while the other sectors detracted from performance. As of period-end, the gross leverage for the Fund, which detracted from performance, was approximately 27%.

Opinions expressed herein are as of March 31, 2020 and are subject to change at any time, are not guaranteed and should not be considered investment advice. Fund holdings and sector allocations are subject to change at any time and are not recommendations to buy or sell any security. Please refer to the Schedule of Investments for a complete list of Fund holdings.

Shares of closed-end investment companies frequently trade at a discount to their net asset value, which may increase investors’ risk of loss. There are risks associated with an investment in the Fund. Investors should consider the Fund’s investment objective, risks, charges and expenses carefully before investing. An investment in the Fund should not constitute a complete investment program.

This document is not an offer to sell securities or the solicitation of an offer to buy securities, nor shall there be any sale or offer of these securities, in any jurisdiction where such sale or offer is not permitted.

The Fund’s shares are only offered through broker/dealers on the secondary market. Unlike an open-end mutual fund, a closed-end fund offers a fixed number of shares for sale. After the initial public offering, shares are bought and sold in the secondary marketplace, and the market price of the shares is determined by supply and demand, not by NAV, often at a lower price than the NAV. A closed-end fund is not required to buy its shares back from investors upon request.

Investing involves risk. Principal loss is possible. Investments in debt securities typically decline in value when interest rates rise. This risk is usually greater for longer-term debt securities. Investments in lower rated and non-rated securities present a great risk of loss to principal and interest than higher rated securities. Investments in asset-backed and mortgage-backed securities include additional risks that investors should be aware of including credit risk, prepayment risk, possible illiquidity and default, as well as increased susceptibility to adverse economic developments. The Fund may invest in foreign securities which involves greater volatility and political, economic and currency risks and differences in accounting methods. These risks are greater for investments in emerging markets. Derivatives involve risks different from, and in certain cases, greater than the risks presented by more traditional investments. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could lose more than the amount invested. Exchange-traded fund investments involve additional risks such as the market price trading at a discount to its net asset value, an active secondary trading market may not develop or be maintained, or trading may be halted by the exchange in which they trade, which may impact a fund’s ability to sell its shares. Investment strategies may not achieve the desired results due to implementation lag, other timing factors, portfolio management decision-making, economic or market conditions or other unanticipated factors. In addition, the Fund may invest in other asset classes and investments. Additional principal risks for the Fund can be found in the prospectus.

Diversification does not assure a profit or protect against loss in a declining market.

The Fund’s investment objectives, risks, charges and expenses must be considered carefully before investing.

Notes to Financial Statements (Unaudited) March 31, 2020

1.  Organization

DoubleLine Income Solutions Fund (the “Fund”) was formed as a closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and originally classified as a non-diversified fund. The Fund is currently operating as a diversified fund. Currently under the 1940 Act, a diversified fund generally may not, with respect to 75% of its total assets, invest more than 5% of its total assets in the securities of any one issuer or own more than 10% of the outstanding voting securities of such issuer (except, in each case, U.S. Government securities, cash, cash items and the securities of other investment companies). The remaining 25% of a fund’s total assets is not subject to this limitation. The Fund was organized as a Massachusetts business trust on January 10, 2013 and commenced operations on April 26, 2013. The Fund is listed on the New York Stock Exchange (“NYSE”) under the symbol “DSL”. The Fund’s primary investment objective is to seek high current income and its secondary objective is to seek capital appreciation.

2.  Significant Accounting Policies

The Fund is an investment company that applies the accounting and reporting guidance issued in Topic 946, “Financial Services—Investment Companies”, by the Financial Accounting Standards Board (“FASB”). The following is a summary of the significant accounting policies of the Fund. These policies are in conformity with accounting principles generally accepted in the United States of America (“US GAAP”).

A. Security Valuation. The Fund has adopted US GAAP fair value accounting standards which establish a definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the measurements of fair value and a discussion of changes in valuation techniques and related inputs during the period. These inputs are summarized in the three broad levels listed below:

• Level 1—Unadjusted quoted market prices in active markets for identical securities

• Level 2—Quoted prices for identical or similar assets in markets that are not active, or inputs derived from observable market data

• Level 3—Significant unobservable inputs (including the reporting entity’s estimates and assumptions)

Market values for domestic and foreign fixed income securities are normally determined on the basis of valuations provided by independent pricing services. Vendors typically value such securities based on one or more inputs described in the following table which is not intended to be a complete list. The table provides examples of inputs that are commonly relevant for valuing particular classes of fixed income securities in which the Fund is authorized to invest. However, these classifications are not exclusive, and any of the inputs may be used to value any other class of fixed-income securities. Securities that use similar valuation techniques and inputs as described in the following table are categorized as Level 2 of the fair value hierarchy. To the extent the significant inputs are unobservable, the values generally would be categorized as Level 3. Assets and liabilities may be transferred between levels.

Fixed-income class	Examples of Inputs
All	Benchmark yields, transactions, bids, offers, quotations from dealers and trading systems, new issues, spreads and other relationships observed in the markets among comparable securities; and proprietary pricing models such as yield measures calculated using factors such as cash flows, financial or collateral performance and other reference data (collectively referred to as “standard inputs”)
Corporate bonds and notes; convertible securities	Standard inputs and underlying equity of the issuer
US bonds and notes of government and government agencies	Standard inputs
Residential and commercial mortgage-backed obligations; asset-backed obligations (including collateralized loan obligations)	Standard inputs and cash flows, prepayment information, default rates, delinquency and loss assumptions, collateral characteristics, credit enhancements and specific deal information, trustee reports
Bank loans	Standard inputs

Investments in registered open-end management investment companies will be valued based upon the net asset value (“NAV”) of such investments and are categorized as Level 1 of the fair value hierarchy.

Common stocks, exchange-traded funds and financial derivative instruments, such as futures contracts or options contracts, that are traded on a national securities or commodities exchange, are typically valued at the last reported sales price, in the case of common stocks and exchange-traded funds, or, in the case of futures contracts or options contracts, the settlement price determined by the relevant exchange. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy.

(Unaudited)

March 31, 2020

Securities may be fair valued by the Adviser (as defined below) in accordance with the fair valuation procedures approved by the Board of Trustees (the “Board”). The Adviser’s valuation committee is generally responsible for overseeing the day to day valuation processes and reports periodically to the Board. The Adviser’s valuation committee and the pricing group are authorized to make all necessary determinations of the fair values of portfolio securities and other assets for which market quotations or third party vendor prices are not readily available or if it is deemed that the prices obtained from brokers and dealers or independent pricing services are deemed to be unreliable indicators of market or fair value.

The following is a summary of the fair valuations according to the inputs used to value the Fund's investments as of March 31, 2020:

¹  Purchases include all purchases of securities, payups and corporate actions.

²  Sales include all sales of securities, maturities, and paydowns.

³  Any difference between Net Change in Unrealized Appreciation (Depreciation) and Net Change in Unrealized Appreciation (Depreciation) on securities held at March 31, 2020 may be due to a security that was not held or categorized as Level 3 at either period end.

⁴  Transfers into or out of Level 3 can be attributed to changes in the availability of pricing sources and/or in the observability of significant inputs used to measure the fair value of those instruments.

The following is a summary of quantitative information about Level 3 Fair Value Measurements:

	Fair Value as of 3/31/2020			Valuation Techniques	Unobservable Input	Unobservable Input Values (Weighted Average)+	Impact to valuation from an increase to input
Non-Agency Commercial Mortgage Backed Obligations		$	70,555,691	Market Comparables	Yields	13.04%-35.00% (17.95%)	Increase in yields would have resulted in the decrease in the fair value of the security
Non-Agency Residential Collateralized Mortgage Obligations		$	55,156,738	Market Comparables	Market Quotes	$91.58-$92.56 ($91.93)	Significant changes in the market quotes would have resulted in direct and proportional changes in the fair value of the security
Common Stocks		$	3,793,251	Market Comparables	Market Quotes	$6.00-$17.50 ($9.39)	Significant changes in the market quotes would have resulted in direct and proportional changes in the fair value of the security
Collateralized Loan Obligations		$	2,737,722	Market Comparables	Market Quotes	$38.33-$72.16 ($51.74)	Significant changes in the market quotes would have resulted in direct and proportional changes in the fair value of the security

⁺  Unobservable inputs were weighted by the relative fair value of the instruments.

B. Federal Income Taxes. The Fund has elected to be taxed as a “regulated investment company” and intends to distribute substantially all of its taxable income to its shareholders and otherwise comply with the provisions of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no provision for federal income taxes has been made.

The Fund may be subject to a nondeductible 4% excise tax calculated as a percentage of certain undistributed amounts of net investment income and net capital gains.

26 DoubleLine Income Solutions Fund

(Unaudited)

March 31, 2020

The Fund has followed the authoritative guidance on accounting for and disclosure of uncertainty in tax positions, which requires the Fund to determine whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Fund has determined that there was no effect on the financial statements from following this authoritative guidance. In the normal course of business, the Fund is subject to examination by federal, state and local jurisdictions, where applicable, for tax years for which applicable statutes of limitations have not expired. The Fund identifies its major tax jurisdictions as U.S. Federal, the Commonwealth of Massachusetts and the State of California.

C. Security Transactions, Investment Income. Investment securities transactions are accounted for on trade date. Gains and losses realized on sales of securities are determined on a specific identification basis. Interest income, including non-cash interest, is recorded on an accrual basis. Discounts/premiums on debt securities purchased, which may include residual and subordinate notes, are accreted/amortized over the life of the respective securities using the effective interest method except for certain deep discount bonds where management does not expect the par value above the bond’s cost to be fully realized. Dividend income and corporate action transactions, if any, are recorded on the ex-date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of securities received. Paydown gains and losses on mortgage-related and other asset-backed securities are recorded as components of interest income on the Statement of Operations.

D. Dividends and Distributions to Shareholders. Dividends from net investment income will be declared and paid monthly. The Fund will distribute any net realized long or short-term capital gains at least annually. Distributions are recorded on the ex-dividend date.

Income and capital gain distributions are determined in accordance with income tax regulations which may differ from US GAAP. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications between paid-in capital, undistributed (accumulated) net investment income (loss), and/or undistributed (accumulated) realized gain (loss). Undistributed (accumulated) net investment income or loss may include temporary book and tax basis differences which will reverse in a subsequent period. Any taxable income or capital gain remaining at fiscal year end is distributed in the following year.

E. Use of Estimates. The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates.

F. Share Valuation. The NAV per share of the Fund is calculated by dividing the sum of the value of the securities held by the Fund, plus cash and other assets, minus all liabilities (including estimated accrued expenses), by the total number of shares outstanding, rounded to the nearest cent. The Fund’s NAV is typically calculated on days when the NYSE opens for regular trading.

G. Unfunded Loan Commitments. The Fund may enter into certain credit agreements, of which all or a portion may be unfunded. As of March 31, 2020, the Fund had no outstanding unfunded loan commitments. The Fund may also enter into certain credit agreements designed to provide standby short term or “bridge” financing to a borrower. Typically the borrower is not economically incented to draw on the bridge loan and as such the likelihood of funding is remote. As of March 31, 2020, the Fund had no outstanding bridge loan commitments. The Fund is obligated to fund these commitments at the borrower’s discretion. The Fund generally will maintain with its custodian liquid investments having an aggregate value at least equal to the par value of unfunded loan commitments and bridge loans.

H. Contingencies. Between 2011 and 2014, the Commonwealth of Puerto Rico issued certain general obligation bonds, which are currently the subject of litigation. The Fund previously purchased and sold certain of these general obligation bonds and may have some exposure to this litigation. At this time, it is anticipated that a material adverse effect on the Fund as a result of this litigation is remote.”

I. Guarantees and Indemnifications. Under the Fund’s organizational documents, each Trustee and officer of the Fund is indemnified, to the extent permitted by the 1940 Act, against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts.

3.  Related Party Transactions

DoubleLine Capital LP (the “Adviser” or “DoubleLine Capital”) provides the Fund with investment management services under an Investment Management Agreement (the “Agreement”). Under the Agreement, the Adviser manages the investment of the assets of the Fund, places orders for the purchase and sale of its portfolio securities and is responsible for providing certain resources to assist with the day-to-day management of the Fund’s business affairs. As compensation for its services, the Adviser is entitled to a monthly fee at the annual rate of 1.00% of the average daily total managed assets of the Fund. Total managed assets means the total assets of the Fund (including assets attributable to any reverse repurchase agreements, dollar roll transactions or similar transactions, borrowings, and/or preferred shares that may be outstanding) minus accrued liabilities (other than liabilities in respect of reverse repurchase agreements, dollar roll transactions or similar transactions, and borrowings). For purposes of calculating total managed assets, the liquidation preference of any preferred shares outstanding shall not be considered a liability. DAMCO, a wholly owned subsidiary of the Adviser, owned 7,839 shares of the Fund as of March 31, 2020. The Adviser has arrangements with DoubleLine Group LP to provide personnel and other resources to the Fund.

4.  Purchases and Sales of Securities

For the period ended March 31, 2020, purchases and sales of investments, excluding short term investments, were $483,936,076 and $868,081,267, respectively. There were no transactions in U.S. Government securities (defined as long-term U.S. Treasury bills, notes and bonds) during the period.

5.  Income Tax Information

The tax character of distributions for the Fund were as follows:

	Period Ended March 31, 2020			Year Ended September 30, 2019
Distributions Paid From:
Ordinary Income		$	96,012,075		$	182,575,029
Total Distributions Paid		$	96,012,075		$	182,575,029

The amount and character of tax-basis distributions and composition of net assets, including undistributed (accumulated) net investment income (loss), are finalized at fiscal year-end; accordingly, tax-basis balances have not been determined as of the date of this report.

The cost basis of investments for federal income tax purposes as of September 30, 2019, was as follows:

Tax Cost of Investments	$	3,047,482,554
Gross Tax Unrealized Appreciation		98,556,691
Gross Tax Unrealized Depreciation		(324,586,112	)
Net Tax Unrealized Appreciation (Depreciation)		(226,019,421	)

As of September 30, 2019, the components of accumulated earnings (losses) for income tax purposes were as follows:

Net Tax Unrealized Appreciation (Depreciation)	$	(226,019,421	)
Undistributed Ordinary Income		5,368,635
Total Distributable Earnings		5,368,635
Other Accumulated Gains (Losses)		(241,960,778	)
Total Accumulated Earnings (Losses)		(462,611,564	)

As of September 30, 2019, $241,923,343 was available as a capital loss carryforward.

The Fund may elect to defer to the first day of the next taxable year all or part of any late-year ordinary loss or post-October capital loss. As of September 30, 2019, the Fund deferred, on a tax basis, qualified late year losses of $0.

Additionally, US GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The permanent differences primarily relate to consent income, market discount, Passive Foreign Investment Companies (PFICs), paydown losses, return of capital and defaulted securities. For the year ended September 30, 2019, the following table shows the reclassifications made:

Undistributed (Accumulated) Net Investment Income  (Loss)		Accumulated Net Realized Gain (Loss)				Paid-In Capital
	$9,898,323		$	(9,898,323	)		$	—

6.  Share Transactions

Transactions in the Fund’s shares were as follows:

	Period Ended March 31, 2020					For the Year Ended September 30, 2019
	Shares		Amount			Shares		Amount
Reinvested Dividends		267,904		$	4,853,765		191,327		$	3,739,274

7.  Trustees Fees

Trustees who are not affiliated with the Adviser and its affiliates received, as a group, fees of $77,598 from the Fund during the period ended March 31, 2020. These trustees may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the Fund, are treated as if invested in shares of the Fund or other funds managed by the Adviser and its affiliates. These amounts represent general, unsecured liabilities of the Fund and vary according to the total returns of the selected funds. Trustees Fees in the Fund’s Statement of Operations are shown as $77,598, which includes $76,027 in current fees (either paid in cash or deferred) and an increase of $1,571 in the value of the deferred amounts. Certain trustees and officers of the Fund are also officers of the Adviser; such trustees and officers are not compensated by the Fund.

8.  Bank Loans

The Fund may make loans directly to borrowers and may acquire or invest in loans made by others (“loans”). The Fund may acquire a loan interest directly by acting as a member of the original lending syndicate. Alternatively, the Fund may acquire some or all of the interest of a bank or other lending institution in a loan to a particular borrower by means of a novation, an assignment or a participation. The loans in which the Fund may invest include those that pay fixed rates of interest and those that pay floating rates—i.e., rates that adjust periodically based on a known lending rate, such as a bank’s prime rate. The Fund may purchase and sell interests in bank loans on a when-issued and delayed delivery basis, with payment delivery scheduled for a future date. Securities purchased on a delayed delivery basis are marked to market daily and no income accrues to the Fund prior to the date the Fund actually takes delivery of such securities. These transactions are subject to market fluctuations and are subject, among other risks, to the risk that the value at delivery may be more or less than the trade purchase price.

9.  Credit Facility

The Fund currently maintains a Liquidity Agreement (the “Liquidity Agreement”) with State Street Bank & Trust Company (“SSB”) that allows the Fund to borrow up to $1 billion (maximum facility amount) and includes an agency securities lending arrangement with SSB. As of March 31, 2020, the amount of total outstanding borrowings was $585,000,000, which approximates fair value. The borrowings are categorized as Level 2 within the fair value hierarchy.

The Fund pledges its assets as collateral to secure obligations under the Liquidity Agreement. The Fund retains the risks and rewards of the ownership of assets pledged to secure obligations under the Liquidity Agreement and generally expects to make these assets available for securities lending transactions. Under the terms of the Liquidity Agreement, the Fund may enter into securities lending transactions initiated by SSB, acting as the Fund’s authorized securities lending agent. All securities lent through SSB are required to be secured with cash collateral received from the securities lending counterparty in amounts at least equal to 102% of the initial market value of the securities lent. Cash collateral received by SSB, in its role as securities lending agent for the Fund, may be used by SSB to fund amounts drawn by the Fund under the Liquidity Agreement. The amount that can be funded through securities lending is limited to 90% of the outstanding borrowings under the Liquidity Agreement. As of March 31, 2020, the fair value of securities on loan is $199,543,353. Any amounts credited against the Liquidity Agreement are considered leverage and would be subject to various limitations in the Liquidity Agreement and the 1940 Act. Upon return to the Fund of loaned securities, the collateral must be returned to the securities lending counterparty, and SSB may either lend other securities of the Fund or may replace such amount through direct loans from SSB. SSB has the option under the Liquidity Agreement to replace amounts lent to the Fund directly by SSB with the proceeds of securities lending transactions, and vice versa, without notice to or consent from the Fund. SSB retains all amounts paid by securities lending counterparties for loaned securities. Borrowers of Fund securities are required to pay the Fund substitute interest, dividends and other distributions paid with respect to any borrowed security. The Fund has the right to call a loan and obtain the securities loaned at any time. In an event of default, any deposits or other sums credited by or due from SSB to the Fund and any collateral in the possession of SSB may be applied to or set off by SSB against the payment of the obligations under the Liquidity Agreement.

Semi-Annual Report March 31, 2020 29

Notes to Financial Statements  (Cont.) (Unaudited) March 31, 2020

In the event of a securities lending counterparty default, SSB has agreed to indemnify the Fund for certain losses that may arise in connection with the default. Although the risk of the loss by the Fund of the securities lent may be mitigated by receiving collateral from the securities lending counterparty and through SSB’s indemnification, the Fund could experience losses on securities loans, a delay in recovering, or an inability to recover, securities on loan, and the Fund could experience a lower than expected return if the securities lending counterparty fails to return the securities on a timely basis.

Interest charged is at the rate of one-month LIBOR (London Interbank Offered Rate) plus 0.70%, subject to certain conditions that may cause that rate of interest to increase. The Fund will also be responsible for paying a non-usage fee of 0.25% of available credit over $150,000,000 that has not been borrowed by the Fund.

The Fund may terminate the Liquidity Agreement with 60 days’ notice. If certain asset coverage and collateral requirements, minimum net assets or other covenants are not met, the Liquidity Agreement could be deemed in default and result in termination. Absent a default or facility termination event, SSB is required to provide the fund with 360 days’ notice prior to terminating the Liquidity Agreement.

For the period ended March 31, 2020, the Fund’s activity under the Liquidity Agreement was as follows:

Maximum Amount Available		Average Borrowings		Maximum Amount Outstanding		Interest Expense		Average Interest Rate
	$1,000,000,000	$	820,191,257	$	870,000,000	$	9,659,353		2.30%

10.  Principal Risks

Below are summaries of some, but not all, of the principal risks of investing in the Fund, each of which could adversely affect the Fund’s NAV, market price, yield, and total return. The Fund’s prospectus provided additional information regarding these and other risks of investing in the Fund at the time of the initial public offering of the Fund’s shares.

• 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.

• collateralized debt obligations risk:  The risks of an investment in a collateralized debt obligation (“CDO”) depend largely on the quality and type of the collateral and the tranche of the CDO in which the Fund invests. Normally, collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other CDOs are privately offered and sold, and thus are not registered under the securities laws. As a result, there may be a limited secondary market for investments in CDOs and such investments may be illiquid. In addition to the risks associated with debt instruments (e.g., interest rate risk and credit risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the Fund may invest in CDOs that are subordinate to other classes of the issuer’s securities; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

• confidential information access risk:  The risk that the intentional or unintentional receipt of material, non-public information by the Adviser could limit the Fund’s ability to sell certain investments held by the Fund or pursue certain investment opportunities on behalf of the Fund, potentially for a substantial period of time.

• counterparty risk:  The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts (whether a clearing corporation in the case of exchange-traded or cleared instruments or another third party in the case of over-the-counter instruments) and other instruments such as repurchase and reverse repurchase agreements entered into by the Fund. Subject to certain limitations for U.S. federal income tax purposes, the Fund is not subject to any limit with respect to the number of transactions it can enter into with a single counterparty. To the extent that the Fund enters into multiple transactions with a single or a small set of counterparties, it will be subject to increased counterparty risk.

• credit default swaps risk:  Credit default swaps involve greater risks than investing in the reference obligation directly as well as liquidity risk, counterparty risk and credit risk. A buyer will lose its investment and recover nothing should no event of default occur. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein since if an event of default occurs the seller must pay the buyer the full notional value of the reference obligation.

30 DoubleLine Income Solutions Fund

(Unaudited)

March 31, 2020

• credit risk:  Credit risk is the risk that one or more of the Fund’s investments in debt securities or other instruments will decline in price, or fail to pay interest, liquidation value or principal when due, because the issuer of the obligation or the issuer of a reference security experiences an actual or perceived decline in its financial status.

• 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 underlying investment; 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 markets 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 the risk of expropriation, nationalization or other adverse political or economic developments.

• 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.

• foreign (non-U.S.) investment risk:  The Fund’s investments in and exposure to foreign securities involve special risks. For example, the value of these investments may decline in response to unfavorable political and legal developments, unreliable or untimely information or economic and financial instability. Foreign securities may experience more rapid and extreme changes in value than investments in securities of U.S. issuers. Investing in securities of issuers based or doing business in emerging markets entails all of the risks of investing in securities of foreign issuers, but to a heightened degree. To the extent that the investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. 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.

• foreign currency risk:  The Fund’s investments in or exposure to foreign currencies or in securities or instruments that trade, or receive revenues, in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions (if used), that the U.S. dollar will decline in value relative to the currency being hedged.

• high yield risk:  The risk that debt instruments rated below investment grade or debt instruments that are unrated and of comparable or lesser quality are predominantly speculative. These instruments, commonly known as “junk bonds,” have a higher degree of default risk and may be less liquid than higher-rated bonds. These instruments may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of high yield investments generally, and less secondary market liquidity.

• interest rate risk:  Interest rate risk is 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.

• inverse floaters and related securities risk:  Investments in inverse floaters, residual interest tender option bonds and similar instruments expose the Fund to the same risks as investments in debt securities and derivatives, as well as other risks, including those associated with leverage and increased volatility. An investment in these securities typically will involve greater risk than an investment in a fixed rate security. Distributions on inverse floaters, residual interest tender option bonds and similar instruments will typically bear an inverse relationship to short term interest rates and typically will be reduced or, potentially, eliminated as interest rates rise.

• investment and market risk:  An investment in the Fund is subject to the risk of loss. The value of the Fund’s securities and financial assets may move up or down, sometimes rapidly and unpredictably. Further, the value of securities held by the Fund may decline in value due to factors affecting securities markets generally or particular industries. Securities markets

Semi-Annual Report March 31, 2020 31

Notes to Financial Statements  (Cont.) (Unaudited) March 31, 2020

may, in response to governmental actions or intervention, economic or market developments, or other external factors, such as those experienced recently in the first calendar quarter of 2020 in response to an outbreak of respiratory disease caused by a novel coronavirus designated as COVID-19, experience periods of high volatility and reduced liquidity. Certain securities may be difficult to value during such periods. These risks may be heightened for fixed income securities due to the current low interest rate environment.

• issuer risk:  The value of securities may decline for a number of reasons that directly relate to the issuer, such as its financial strength, management performance, financial leverage and reduced demand for the issuer’s goods and services, as well as the historical and prospective earnings of the issuer and the value of its assets.

• leverage risk:  Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. When leverage is used, the net asset value and market price of the Fund’s shares and the Fund’s investment return will likely be more volatile.

• LIBOR risk:  The terms of many investments, financings or other transactions to which the Fund may be a party have been historically tied to the London Interbank Offered Rate, or “LIBOR.” LIBOR is the offered rate at which major international banks can obtain wholesale, unsecured funding, and LIBOR may be available for different durations (e.g., 1 month or 3 months) and for different currencies. LIBOR may be a significant factor in determining the Fund’s payment obligations under a derivative investment, the cost of financing to the Fund or an investment’s value or return to the Fund, and may be used in other ways that affect the Fund’s investment performance. In July 2017, the Financial Conduct Authority, the United Kingdom’s financial regulatory body, announced that after 2021 it will cease its active encouragement of banks to provide the quotations needed to sustain LIBOR. That announcement suggests that LIBOR may cease to be published after that time. Various financial industry groups have begun planning for that transition, but there are obstacles to converting certain securities and transactions to a new benchmark. Transition planning is at an early stage, and neither the effect of the transition process nor its ultimate success can yet be known. The transition away from LIBOR might lead to increased volatility and illiquidity in markets for instruments whose terms currently include LIBOR, reduce the effectiveness of new hedges placed against existing LIBOR-based investments, increased costs for certain LIBOR-related instruments or financing transactions and cause prolonged adverse market conditions for the Fund. All of the aforementioned may adversely affect the Fund’s performance or NAV.

• liquidity risk:  The risk that a Fund may be unable to sell a portfolio investment at a desirable time or at the value the Fund has placed on the investment.

• loan risk:  Investments in loans are in many cases subject to the risks associated with below-investment grade securities. Investments in loans are also subject to special risks, including, among others, the risk that (i) if the Fund holds a loan through another financial institution, or relies on a financial institution to administer the loan, the Fund’s receipt of principal and interest on the loan is subject to the credit risk of that financial institution; (ii) loans in which the Fund invests typically pay interest at floating rates, and the borrower may have the ability to change or adjust the interest rate on a loan or under circumstances that would be unfavorable to the Fund; (iii) it is possible that any collateral securing a loan may be insufficient or unavailable to the Fund; (iv) investments in highly leveraged loans or loans of stressed, distressed, or defaulted issuers may be subject to significant credit and liquidity risk; (v) transactions in loans may settle on a delayed basis, and the Fund potentially may not receive the proceeds from the sale of a loan for a substantial period of time after the sale; (vi) 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; and (vii) loans may be difficult to value and may be illiquid, which may adversely affect an investment in the Fund. It is unclear whether the protections of the securities laws against fraud and misrepresentation extend to loans and other forms of direct indebtedness. In the absence of definitive regulatory guidance, the Fund relies on the Adviser’s research in an attempt to avoid situations where fraud or misrepresentation could adversely affect the Fund. There can be no assurance that the Adviser’s efforts in this regard will be successful.

• market discount risk:  The price of the Fund’s common shares of beneficial interest will fluctuate with market conditions and other factors. Shares of closed-end management investment companies frequently trade at a discount from their net asset value.

• mortgage-backed securities risk:  The risk that borrowers may default on their mortgage obligations or the guarantees underlying the mortgage-backed securities will default or otherwise fail and that, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security’s duration, and reduce the value of the

security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates. The Fund may invest in mortgage-backed securities that are subordinate in their right to receive payment of interest and re-payment of principal to other classes of the issuer’s securities.

• operational risk:  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 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.

• restricted securities risk:  The risk that the Fund may be prevented or limited by law or the terms of an agreement from selling a security (a “restricted security”). To the extent that the Fund is permitted to sell a restricted security, there can be no assurance that a trading market will exist at any particular time and the Fund may be unable to dispose of the security promptly at reasonable prices or at all. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the values of restricted securities may have significant volatility.

• sovereign debt obligations risk:  Investments in countries’ government debt obligations involve special risks. The issuer or governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of such debt or otherwise in a timely manner.

11.  Subsequent Events

In preparing these financial statements, the Fund has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued. The Fund has determined there are no additional subsequent events that would need to be disclosed in the Fund’s financial statements.

At an in-person meeting in February 2020, the Boards of Trustees (the “Board” or the “Trustees”) of the DoubleLine open-end mutual funds and closed-end funds (the “Funds”) approved the continuation of the investment advisory and sub-advisory agreements (the “Advisory Agreements”) between DoubleLine and those Funds. That approval included approval by the Trustees who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Funds (the “Independent Trustees”) voting separately. When used in this summary, “DoubleLine” refers collectively to DoubleLine Capital LP and to DoubleLine Alternatives LP.

The Trustees’ determination to approve the continuation of each Advisory Agreement was made on the basis of each Trustee’s business judgment after an evaluation of all of the information provided to the Trustees, including information provided for their consideration at their February 2020 meeting with management and at meetings held in preparation for that February 2020 meeting, including portions held outside the presence of management, specifically to review and consider materials related to the proposed continuation of each Advisory Agreement. The Trustees meet over the course of the year with investment advisory, compliance, and other personnel from DoubleLine and regularly review detailed information, presented both orally and in writing, regarding the services performed by DoubleLine for the benefit of the Funds and the investment program, performance, and operations of each Fund. In considering whether to approve the continuation of the Advisory Agreements, the Trustees took into account information presented to them over the course of the past year.

This summary describes a number, but not necessarily all, of the most important factors considered by the Board and the Independent Trustees. Individual Trustees may have given different weights to certain factors and assigned various degrees of materiality to information received in connection with the approval process. No single factor was determined to be decisive. In all of their deliberations, the Independent Trustees were advised by independent counsel.

The Trustees considered the nature, extent, and quality of the services, including the expertise and experience of investment personnel, provided and expected to be provided by DoubleLine to each Fund. In this regard, the Trustees considered that DoubleLine provides a full investment program for the Funds, and noted DoubleLine’s representation that it seeks to provide attractive returns with a strong emphasis on risk management. The Board considered in particular the difficulty of managing debt related portfolios, noting that managing such portfolios requires a portfolio management team to balance a number of factors, which may include, among others, securities of varying maturities and durations, actual and anticipated interest rate changes and volatility, prepayments, collateral management, counterparty management, pay-downs, credit events, workouts, and net new issuances. In their evaluation of the services provided by DoubleLine and the Funds’ contractual relationships with DoubleLine, the Trustees considered generally the long-term performance record of the firm’s portfolio management personnel, including among others Mr. Jeffrey Gundlach, and the strong overall demand for products managed by DoubleLine.

(Unaudited)

March 31, 2020

The Trustees reviewed reports (the “Strategic Insight Reports”) provided by Strategic Insight, an Asset International Company (“Strategic Insight”), that compared each open-end Fund’s net management fee ratio and net total expense ratio (Class I shares) against its Strategic Insight peer group, and each open-end Fund’s performance records (Class I shares) for the one-year, three-year (where applicable) and five-year (where applicable) periods ended December 31, 2019 against its Morningstar category. The Independent Trustees met with Strategic Insight representatives to review Strategic Insight’s selection of peer groups, including the factors Strategic Insight considers in assembling peer groups of funds for the various Funds.

With respect to the comparative performance information in the Strategic Insight Reports, the Trustees noted in particular that each open-end Fund, other than DoubleLine Floating Rate Fund (“Floating Rate”), DoubleLine Low Duration Emerging Markets Fixed Income Fund (“Low Duration EMFI”), DoubleLine Global Bond Fund (“Global Bond”), DoubleLine Ultra Short Fund (“Ultra Short”), and DoubleLine Shiller Enhanced International CAPE (“International CAPE”), was in the first or second performance quartile relative to its respective Morningstar category for the longest period ended December 31, 2019 for which comparative performance information was presented by Strategic Insight. The Trustees considered specific factors cited by DoubleLine for any relative underperformance of the open-end Funds, which in most cases resulted from decisions of the Funds’ portfolio management team as to risk management and the overall positioning and strategy of the Funds. In respect of Low Duration EMFI and Ultra Short, the Trustees considered DoubleLine’s explanation that conservative credit and duration positioning contributed significantly to the relative performance of those Funds. In respect of Floating Rate, the Trustees considered DoubleLine’s representation that conservative credit positioning contributed to the relative underperformance of that Fund. The Trustees also considered information Strategic Insight and DoubleLine provided regarding peer group construction issues and differences in investment mandate in their evaluations of the relative performance of Low Duration EMFI, Global Bond and International CAPE.

The Trustees considered the portion of the Strategic Insight Reports covering the open-end Funds’ expenses and advisory fees, noting that the reports showed that each open-end Fund, other than DoubleLine Emerging Markets Fixed Income Fund (“EMFI”), DoubleLine Multi-Asset Growth Fund (“MAG”), DoubleLine Long Duration Total Return Fund (“Long Duration Total Return”), DoubleLine Strategic Commodity Fund (“Strategic Commodity”), and DoubleLine Infrastructure Income Fund (“Infrastructure Income”), had a net total expense ratio in the first or second quartile of its peer group. The Trustees noted that none of the Funds had a net total expense ratio that was in the fourth comparative quartile of its peer group and that EMFI and Infrastructure Income were within four basis points (or less) of its expense group median.

The Trustees considered each open-end Fund’s net management fee ratio relative to its expense peer group and, in respect of those Funds with a net management fee ratio above the median of its peer group, the Trustees considered DoubleLine’s pricing policy for its advisory fees and that DoubleLine does not seek to be a lowest cost provider, nor does it have a policy to set its advisory fees below the median of a Fund’s peers. In respect of MAG, Long Duration Total Return, Strategic Commodity and Infrastructure Income, each of which had a net management fee that fell in the fourth quartile of its expense peer group, the Trustees considered the long-term relative performance of those Funds and that each had performed in either the first or second quartile of its Morningstar category over the longest-period of performance shown in the Strategic Insight report. The Trustees also considered information provided by DoubleLine that reflected differences in investment mandate, approach or flexibility between each of those Funds and the bulk of their peers generally, as well as DoubleLine’s undertaking to reduce the management fee of Long Duration Total Return to a level that would have been below the median of its expense peer group had it been in effect at the time the comparative information was compiled.

As to the Opportunistic Credit Fund (“DBL”), the Trustees noted that DBL’s net management fee ratio and net total expense ratio were shown in the Strategic Insight Reports to be higher than the median of the Fund’s peer group. The Trustees noted DBL’s favorable relative long-term performance, with its performance ranking in the second quartile of its Morningstar peer group for the five-year period ended December 31, 2019. They also noted its less favorable performance over the three- and one-year periods ended December 31, 2019. The Trustees considered DoubleLine’s explanation for DBL’s recent underperformance, including its greater focus on investment in mortgage-backed securities and its more limited exposure to credit risk than many of its more diversified peers.

As to the Income Solutions Fund (“DSL”), the Trustees noted that, although DSL was shown in the Strategic Insight Reports to have performed in the fourth quartile of its peers over the one-year period ended December 31, 2019, it performed in the first quartile of its Morningstar peer group over the three- and five-year periods ended December 31, 2019. They noted that DSL’s net management fee ratio and net total expense ratio were higher than the median of its peer group, though both were in the third quartile of the peer group. In evaluating the comparative net management fee and net total expense ratio of DSL, the Trustees considered DSL’s favorable relative performance and DoubleLine’s statement that the Fund’s fees reflect the experience and expertise DoubleLine brings to managing the Fund. The Trustees noted that both DBL and DSL had employed leverage for the

Semi-Annual Report March 31, 2020 35

Evaluation of Advisory Agreement by the Board of Trustees  (Cont.) (Unaudited) March 31, 2020

period shown in the Strategic Insight Reports, and considered information from DoubleLine intended to show that each Fund’s use of leverage was accretive to the Fund’s investment performance, after taking into account any expenses related to the leverage.

The Trustees considered that DoubleLine provides a variety of other services to the Funds in addition to investment advisory services, including, among others, a number of back-office services, valuation services, compliance services, certain forms of information technology services (such as internal reporting), assistance with accounting and distribution services, and supervision and monitoring of the Funds’ other service providers. The Trustees considered DoubleLine’s ongoing efforts to keep the Trustees informed about matters relevant to the Funds and their shareholders. The Trustees also considered the nature and structure of the Funds’ compliance program, including the policies and procedures of the Funds and their various service providers (including DoubleLine). The Trustees considered the quality of those non-investment advisory services and determined that their quality appeared to support the continuation of the Funds’ arrangements with DoubleLine.

The Trustees considered DoubleLine’s reports, provided at the Board’s regular meetings, that it had continued to hire additional resources and to invest in technology enhancements to support DoubleLine’s ability to provide services to the Funds. The Trustees concluded that it appeared that DoubleLine continued to have sufficient quality and depth of personnel, resources, and investment methods.

The Trustees considered materials relating to the fees charged by DoubleLine to non-Fund clients for which DoubleLine employs investment strategies substantially similar to one or more Funds’ investment strategies, including institutional separate accounts advised by DoubleLine and mutual funds for which DoubleLine serves as subadviser. The Trustees noted the information DoubleLine provided regarding certain institutional separate accounts advised by it and funds subadvised by it that are subject to fee schedules that differ from, including those that are lower than, the rates paid by a Fund with substantially similar investment strategies. The Trustees noted DoubleLine’s representations that administrative, compliance, operational, legal, and other burdens of providing investment advice to mutual funds exceed in many respects those required to provide advisory services to non-mutual fund clients, such as institutional accounts for retirement or pension plans, which may have differing contractual requirements. The Trustees noted DoubleLine’s representations that DoubleLine bears substantially greater legal and other responsibilities and risks in managing and sponsoring mutual funds than in managing private accounts or in subadvising mutual funds sponsored by others, and that the services and resources required of DoubleLine when it subadvises mutual funds sponsored by others generally are less extensive than those required of DoubleLine to serve the Funds, because, where DoubleLine serves as a subadviser, many of the sponsorship, operational, and compliance responsibilities related to the advisory function are retained by the primary adviser.

The Trustees reviewed information as to general estimates of DoubleLine’s profitability with respect to each Fund, taking into account both the direct and the indirect benefits to DoubleLine from managing the Funds. The Trustees considered information provided by DoubleLine as to the methods it uses, and the assumptions it makes, in calculating its profitability. The Trustees considered representations from DoubleLine that its compensation and incentive policies and practices enable DoubleLine to attract, retain, and motivate highly qualified and experienced employees. The Trustees noted that DoubleLine experienced significant profitability in respect of certain of the Funds, but noted that in those cases it would be appropriate to consider that profitability in light of various other considerations such as the nature, extent, and quality of the services provided by DoubleLine, the relative performance of the Funds, and the competitiveness of the management fees and total operating expenses of the Funds. The Trustees separately considered DoubleLine’s statement that it is continuing to invest in its business to maintain its ability to provide high-quality services to the Funds, and noted DoubleLine’s need to invest in technology, infrastructure, and staff to continue to provide services and accommodate rapidly changing regulatory requirements.

In their evaluation of economies of scale, the Trustees considered, among other things, the pricing of the Funds, DoubleLine’s reported profitability and that a number of the open-end Funds had achieved significant size. They noted also that none of the Funds has breakpoints in its advisory fee schedule, though the Trustees considered management’s view that the fee schedules for the Funds remained consistent with DoubleLine’s original pricing philosophy of proposing an initial management fee rate that generally reflects reasonably foreseeable economies of scale instead of relying on breakpoints in a Fund’s management fee rate. In this regard, the Trustees noted also that the information provided by Strategic Insight supported the view that the largest open-end Funds’ net management fees remained fairly priced, with all but two of the open-end Funds with $1 billion in assets under management or more having net management fees below the median of their peer groups. The Trustees noted that, although DoubleLine Total Return Bond Fund and EMFI had net management fees above their median, their net management fees were within 4 and 2 basis points, respectively, of their respective medians. The Trustees further noted that DoubleLine was subsidizing the expenses of a number of other Funds with less scale, with the prospect of recouping those fees at a later date. In evaluating economics of scale more generally, the Trustees also noted DoubleLine’s continued growth and ongoing changes to the regulatory

(Unaudited)

March 31, 2020

environment, each of which required DoubleLine to re-invest in its business and infrastructure. On the basis of these factors and others, the Trustees concluded that it was not necessary at the present time to implement breakpoints for any of the Funds, although they would continue to consider the question periodically in the future.

With regard to DBL and DSL, the Trustees noted that these Funds have not increased in assets significantly from their initial offerings due principally to their status as closed-end investment companies and that there were therefore no substantial increases in economies of scale realized with respect to these Funds since their inception. They noted DoubleLine’s view that the levels of its profitability in respect of DBL and DSL are appropriate in light of the investment it has made in these Funds, the quality of the investment management and other teams provided by it, and its continued investments in its own business.

On the basis of these considerations as well as others and in the exercise of their business judgment, the Trustees determined that they were satisfied with the nature, extent, and quality of the services provided to each Fund under its Advisory Agreement(s); that it appeared that the management fees paid by each Fund to DoubleLine were generally within the range of management fees paid by its peer funds, and, with respect to a number of Funds, lower than the median management fees paid by their peer funds, and generally reasonable in light of the services provided, the quality of the portfolio management teams, and each Fund’s performance to date; that the fees paid by each Fund did not appear inappropriate in light of the fee schedules charged to DoubleLine’s other clients with substantially similar investment strategies (where applicable) in light of the differences in the services provided and the risks borne by DoubleLine; that the profitability of each Fund to DoubleLine did not appear excessive or such as to preclude continuation of the Fund’s Advisory Agreement; that absence of breakpoints in any Fund’s management fee did not render that Fund’s fee unreasonable or inappropriate under the circumstances, although the Trustees would continue to consider the topic over time; and that it would be appropriate to approve each Advisory Agreement for an additional one-year period.

Statement Regarding the Fund’s Liquidity Risk Management Program (Unaudited) March 31, 2020

The Fund has adopted a liquidity risk management program. The program’s principal objectives include mitigating the risk that the Fund is unable to meet its redemption obligations timely and supporting the Fund’s compliance with its limits on investments in illiquid assets. Since the program’s inception through the end of the period covered by this report, the program administrator determined that the program supported the Fund’s ability to honor redemption requests timely and the Adviser’s management of the Fund’s liquidity profile. The program includes a number of elements that support the assessment and management of liquidity risk, including the periodic classification and re-classification of the Fund’s investments into groupings based on the Adviser’s view of their liquidity. There can be no assurance that the program will achieve its objectives. Please refer to your Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other risks to which an investment in the Fund may be subject.

Semi-Annual Report March 31, 2020 39

Additional Information Regarding the Fund’s Investment Activities (Unaudited) March 31, 2020

Investments in Pools of Loans: The Fund may invest in pools of loans through mortgage- or other asset-backed securities, where a trust or other entity issues interests in the loans, some of which interests may be senior to others. Alternatively, the Fund may invest directly in pools of loans, itself or with other clients of the Adviser or their related parties. The Fund’s direct investments in pools of loans present risks that may differ from the Fund’s investments in mortgage- and other asset-backed securities. For example, if it were to invest directly in such a pool without any co-investors, the Fund would incur all losses incurred on the loans acquired in the pool. However, if the Fund were to invest in a senior tranche of a mortgage- or other asset-backed security, it might have a more limited exposure to losses on the loans. In connection with the Fund’s direct purchase of certain loan portfolios, the Fund will incur costs, which may include the costs of various diligence-related services. The diligence-related services the Fund may require in connection with such investments may include, without limitation, loan file review, underwriting documentation review, and site visits. The Adviser would typically rely on information and analyses furnished as part of these diligence-related services in determining whether to invest in a particular loan portfolio. The costs associated with investments in a pool of loans may be significant and will reduce the performance contribution of such investments. The Fund may invest in pools of loans through CDOs and other structured products sponsored or managed by, or otherwise affiliated with, the Adviser or related parties of the Adviser. Such investments may include investments in debt or equity interests issued of the CDO or structured product as well as investments purchased on the secondary market, and the Fund may invest in any tranche of the CDO or structured product, including an equity tranche.

Original Issuance, Subordinated Tranche Investments: The Fund may invest in any level of the capital structure of an issuer of mortgage-backed or asset-backed securities, including the equity or “first loss” tranche. Senior tranche investments in mortgage-backed or asset-backed securities are paid from the cash flows from the underlying assets before the junior tranches and equity or “first loss” tranches. Any losses on the underlying assets are first borne by the equity tranches, next by less junior tranches, and finally by the senior tranches. Accordingly, subordinated tranche investments, and especially “first loss” tranches, involve greater risk of loss than more senior tranches. The subordinated tranches the Fund may buy include those rated below investment grade or unrated instruments of similar credit quality. Below investment grade bonds are high yield, high risk bonds, commonly known as junk bonds.

The Adviser may aggregate the Fund’s order for an investment in, or sale of, an interest in a subordinated tranche, including investments at original issuance, with orders of one or more other DoubleLine funds or other DoubleLine accounts. Certain diligence-related or structuring costs and expenses will be allocated to all of the accounts, including the Fund, participating in the aggregated transaction pro rata based on the amount of investment made by each account participating in the transaction. The Fund’s participation in any such aggregated transaction will be subject to a number of conditions intended to result in the fair and equitable treatment of each participating account, including the Fund. For example, the Fund will not incur diligence- or structuring-related expenses in connection with any such transaction in excess of 0.50% of the value of the Fund’s investment in the structured product without the Fund’s Board of Trustees review of those expenses. The Adviser may advance diligence- or structuring-related expenses relating to such transactions on behalf of the Fund and seek to receive reimbursement (without interest) of any such expenses advanced on behalf of the Fund at a later date.

Affiliated Investments: The Adviser is, and may be in the future, affiliated with certain large financial institutions (“affiliates”) that hold interests in an entity that are of a different class or type than the class or type of interest held by the Fund. Conflicts may arise in cases where the Fund and affiliates invest in different parts of an issuer’s capital structure, such as when an affiliate holds securities in an entity that are senior or junior to the securities held by the Fund, which could mean that the affiliate will be entitled to different payments or other rights, or that in a workout or other distressed scenario the interests of the affiliate might be adverse to those of the Fund and the affiliate and the Fund might have disparate investment outcomes. For example, an affiliate may acquire a loan, loan participation, or a loan assignment of a particular borrower in which one or more Funds have an equity investment. In negotiating the terms and conditions of any such investments, or any subsequent amendments or waivers, the Adviser may find that its own interests, the interests of an affiliate, and/or the interests of the Fund could conflict. The Adviser may seek to avoid such conflicts in certain circumstances when investing on behalf of its clients, including the Fund, and, as a result, the Adviser may choose not to make certain investments on behalf of the Fund and/or its other clients. Those foregone investment opportunities may adversely affect the Fund’s performance if similarly attractive opportunities are not available or cannot be identified.

Stapled Securities: The Fund may invest in stapled securities, which are financial instruments comprised of two or more different instruments that are contractually bound to form a single salable unit; they cannot be bought or sold separately. Stapled securities may often include a share in a company and a unit in a trust related to that company. The resulting security is influenced by both parts, and must be treated as one unit at all times, such as when buying or selling a security. The value of stapled securities and the income, if any, derived from them may fall as well as rise. The market for stapled securities may be illiquid at times, even for those securities that are listed on a domestic or foreign exchange.

Capital Controls: Capital controls are measures a nation’s government can use to regulate capital entering and/or exiting a country and may include residency-based measures such as transaction taxes, limits or outright prohibitions on the transfer of currencies, securities or other assets. These measures may be economy-wide, sector-specific (usually the financial sector), or industry specific (for example, “strategic” industries). They may apply to all flows, or may differentiate by type or duration of the flow (debt, equity, direct investment; short-term vs. medium- and long-term). Types of capital controls include exchange controls that prevent or limit the buying and selling of a national currency at the market rate, caps on the allowed volume for the international sale or purchase of various financial assets, transaction taxes, minimum stay requirements, requirements for mandatory approval, or even limits on the amount of money a private citizen is allowed to remove from the country. The imposition of capital controls by a government of a country in which the Fund invests may significantly and adversely affect the values and liquidity of a Fund’s investments in the affected jurisdiction and may prevent indefinitely the repatriation of a Fund’s assets from the affected jurisdiction.

Dividend Reinvestment Plan (Unaudited) March 31, 2020

Unless the registered owner of Common Shares elects to receive cash by contacting U.S. Bancorp Fund Services, LLC (the “Plan Administrator”), all dividends, capital gains and returns of capital, if any, declared on Common Shares will be automatically reinvested by the Plan Administrator for shareholders in the Fund’s Automatic Dividend Reinvestment Plan (the “Plan”), in additional Common Shares. Common Shareholders who elect not to participate in the Plan will receive all dividends and other distributions payable in cash directly to the shareholder of record (or, if the Common Shares are held in street or other nominee name, then to such nominee) by the Plan Administrator as dividend disbursing agent. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by providing notice in writing to the Plan Administrator at least 5 days prior to the dividend/distribution record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution.

Whenever the Fund declares an income dividend, a capital gain distribution or other distribution (collectively referred to as “dividends”) payable either in shares or cash, non-participants in the Plan will receive cash and participants in the Plan will receive a number of Common Shares, determined in accordance with the following provisions. The Common Shares will be acquired by the Plan Administrator for the participants’ accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized Common Shares from the Fund (“Newly Issued Common Shares”) or (ii) by purchase of outstanding Common Shares on the open market (“Open- Market Purchases”) on the New York Stock Exchange or elsewhere. If, on the payment date for any Dividend, the market price per Common Share plus estimated brokerage trading fees is equal to or greater than the NAV per Common Share (such condition is referred to here as “market premium”), the Plan Administrator shall receive Newly Issued Common Shares, including fractions of shares from the Fund for each Plan participant’s account. The number of Newly Issued Common Shares to be credited to each participant’s account will be determined by dividing the dollar amount of the Dividend by the NAV per Common Share on the date of issuance; provided that, if the NAV per Common Share is less than or equal to 95% of the current market value on the date of issuance, the dollar amount of the Dividend will be divided by 95% of the market price per Common Share on the date of issuance for purposes of determining the number of shares issuable under the Plan. If, on the payment date for any Dividend, the NAV per Common Share is greater than the market value plus estimated brokerage trading fees (such condition being referred to here as a “market discount”), the Plan Administrator will seek to invest the Dividend amount in Common Shares acquired on behalf of the participants in Open-Market Purchases.

In the event of a market discount on the payment date for any Dividend, the Plan Administrator will have until the last business day before the next date on which the Common Shares trade on an “ex-dividend” basis or in no event more than 30 days after the record date for such Dividend, whichever is sooner (the “Last Purchase Date”), to invest the Dividend amount in Common Shares acquired in Open-Market Purchases. It is contemplated that the Fund will pay monthly Dividends. If, before the Plan Administrator has completed its Open-Market Purchases, the market price per Common Share exceeds the NAV per Common Share, the average per Common Share purchase price paid by the Plan Administrator may exceed the NAV of the Common Shares, resulting in the acquisition of fewer Common Shares than if the Dividend had been paid in Newly Issued Common Shares on the Dividend payment date. If the Plan Administrator is unable to invest the full Dividend amount in Open-Market Purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Administrator may cease making Open-Market Purchases and may instead receive the Newly Issued Common Shares from the Fund for each participant’s account, in respect of the uninvested portion of the Dividend, at the NAV per Common Share at the close of business on the Last Purchase Date provided that, if the NAV is less than or equal to 95% of the then current market price per Common Share, the dollar amount of the Dividend will be divided by 95% of the market price on the date of issuance for purposes of determining the number of shares issuable under the Plan.

The Plan Administrator maintains all registered shareholders’ accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by shareholders for tax records. Common Shares in the account of each Plan participant will be held by the Plan Administrator in non-certificated form in the name of the Plan participant, and each shareholder proxy will include those shares purchased or received pursuant to the Plan. The Plan Administrator will forward all proxy solicitation materials to participants and vote proxies for shares held under the Plan in accordance with the instructions of the participants.

In the case of Common Shares owned by a beneficial owner but registered with the Plan Administrator in the name of a nominee, such as a bank, a broker or other financial intermediary (each, a “Nominee”), the Plan Administrator will administer the Plan on the basis of the number of Common Shares certified from time to time by the Nominee as participating in the Plan. The Plan Administrator will not take instructions or elections from a beneficial owner whose Common Shares are registered with the Plan Administrator in the name of a Nominee. If a beneficial owner’s Common Shares are held through a Nominee and are not registered with the Plan Administrator as participating in the Plan, neither the beneficial owner nor the Nominee will be participants in or have distributions reinvested under the Plan with respect to those Common Shares. If a beneficial owner of

Semi-Annual Report March 31, 2020 43

Dividend Reinvestment Plan  (Cont.) (Unaudited) March 31, 2020

Common Shares held in the name of a Nominee wishes to participate in the Plan, and the Shareholder’s Nominee is unable or unwilling to become a registered shareholder and a Plan participant with respect to those Common Shares on the beneficial owner’s behalf, the beneficial owner may request that the Nominee arrange to have all or a portion of his or her Common Shares registered with the Plan Administrator in the beneficial owner’s name so that the beneficial owner may be enrolled as a participant in the Plan with respect to those Common Shares. Please contact your Nominee for details or for other possible alternatives. Participants whose shares are registered with the Plan Administrator in the name of one Nominee may not be able to transfer the shares to another firm or Nominee and continue to participate in the Plan.

There will be no brokerage charges with respect to Common Shares issued directly by the Fund as a result of dividends payable either in Common Shares or in cash. However, each participant will pay a pro rata share of brokerage trading fees incurred in connection with Open-Market Purchases. The automatic reinvestment of Dividends will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such Dividends. Participants that request a sale of Common Shares through the Plan Administrator are subject to brokerage commissions.

The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants with regard to purchases in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants.

All correspondence, questions, or requests for additional information concerning the Plan should be directed to the Plan Administrator by calling toll-free 877-DLine11 (877-354-6311) or by writing to U.S. Bancorp Fund Services, LLC at P.O. Box 701, Milwaukee, WI 53201. Be sure to include your name, address, daytime phone number, Social Security or tax I.D. number and a reference to DoubleLine Income Solutions Fund on all correspondence.

The Plan Administrator accepts instructions only from the registered owners of accounts. If you purchased or hold your Fund shares through an intermediary, in most cases your intermediary’s nominee will be the registered owner with the Fund. Accordingly, questions regarding your participation in the Plan or the terms of any reinvestments should be directed to your intermediary in the first instance.

• where the recipient is located in the U.S., it may be a certified member of the EU-U.S. Privacy Shield scheme.

In other circumstances, the law may permit us to otherwise transfer your personal information outside the EEA. In all cases, however, any transfer of your personal information will be compliant with applicable data protection law.

Retention of personal information and security

Your personal information will be retained for as long as required:

• for the purposes for which the personal information was collected;

• in order to establish or defend legal rights or obligations or to satisfy any reporting or accounting obligations; and/or

• as required by data protection laws and any other applicable laws or regulatory requirements, including, but not limited to, U.S. laws and regulations applicable to our business.

We will undertake commercially reasonable efforts to protect the personal information that we hold with appropriate security measures.

If you are an investor in the DoubleLine funds, certain of the rights described above that may apply to direct clients of DoubleLine domiciled or resident outside the United States will not apply to you. In addition, if you invest in a DoubleLine fund through a financial intermediary, DoubleLine may not have access to personal information about you.

If you wish to exercise any of the rights set out above, please contact privacy@doubleline.com.
