This report must be preceded or accompanied by a prospectus. To obtain a summary prospectus, if available, or prospectus for any of our funds, refer to the Account Management Resources information provided in the back of this booklet. We advise you to consider the fund's objectives, risks, charges and expenses carefully before investing. The summary prospectus and prospectus contain this and other important information about the fund. Please read the prospectus carefully before you invest.

The fund invests in commodity-linked derivatives which may subject the fund to special risks. Market price movements or regulatory and economic changes will have a significant impact on the fund’s performance. Any fund that concentrates in a particular segment of the market will generally be more volatile than a fund that invests more broadly. A counterparty with whom the fund does business may decline in financial health and become unable to honor its commitments, which could cause losses for the fund. Bond investments are subject to interest-rate, credit, liquidity and market risks to varying degrees. When interest rates rise, bond prices generally fall. Credit risk refers to the ability of an issuer to make timely payments of principal and interest. Investing in derivatives entails special risks relating to liquidity, leverage and credit that may reduce returns and/or increase volatility. Emerging markets tend to be more volatile than the markets of more mature economies, and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. Investing in foreign securities presents certain risks, such as currency fluctuations, political and economic changes, and market risks. The fund may lend securities to approved institutions. See the prospectus for details.

Letter to Shareholders

Dear Shareholder:

Despite slow growth during the first half of 2015, the U.S. economy’s underlying fundamentals remain sound. Employment growth has been solid, the housing market continues to improve and households have strengthened their finances. Real income is firming thanks to the improving labor market and lower energy prices. And, while consumers remain cautious, they’re likely to loosen their purse strings over time.

In short, our economists see an environment that should support modestly above-trend domestic growth. The strong U.S. dollar continues to act as a headwind to exports and (for those whose positions are not hedged) a detractor from foreign equity returns.

The U.S. Federal Reserve Board is likely to start raising short-term interest rates in the U.S. later this year. However, the specific timing depends on whether the recent slowdown in activity reverses, the labor markets continue to heal and inflation truly bottoms. In any case, analysts expect the process to be gradual.

Meanwhile, the global picture, which had appeared to be brightening, is again in flux due to uncertainties regarding the Greek debt crisis and its potential ramifications. Overall, our strategic view remains generally positive. While we do not see Greece posing a major risk of contagion across the Eurozone, heightened volatility can be expected.

As always, we encourage you to visit us at deutschefunds.com for timely information about economic developments and your Deutsche fund investment. With frequent updates from our Chief Investment Officer and economists, we want to ensure that you have the resources you need to make informed decisions.

Thank you for your continued investment. We appreciate the opportunity to serve your investment needs.

Best regards,

Portfolio Management Review (Unaudited)

Market Overview and Fund Performance

All performance information below is historical and does not guarantee future results. Returns shown are for Class A shares, unadjusted for sales charges. Investment return and principal fluctuate, so your shares may be worth more or less when redeemed. Current performance may differ from performance data shown. Please visit deutschefunds.com for the most recent month-end performance of all share classes. Fund performance includes reinvestment of all distributions. Unadjusted returns do not reflect sales charges and would have been lower if they had. Please refer to pages 12 through 13 for more complete performance information.

Investment Strategy

Under normal circumstances, the fund invests in commodity-linked derivative instruments backed by a portfolio of fixed-income investments.

The fund invests in commodity-linked derivative instruments (a contract whose value is based on a particular commodity), such as commodity-linked swap contracts, commodity-linked structured notes, options and futures contracts, to gain exposure to the investment return of assets that trade in the commodity markets, without investing directly in physical commodities. Physical commodities are assets that have tangible properties, such as gas, heating oil, industrial and other precious metals, livestock or agricultural products.

With respect to the fund’s fixed-income investments, portfolio management uses a relative value style to seek to construct a diversified portfolio of fixed income securities. Management normally targets a dollar-weighted average portfolio duration of three years or less. Please see the fund’s prospectus for a complete description of the commodity-linked derivative and other securities in which the fund invests, including a variety of fixed-income securities.

The fund returned -12.65% during the 12-month period ended June 30, 2015. While negative, this return nonetheless compares favorably to the –23.71% return of the benchmark — the Bloomberg Commodity Index — as well as the –24.74% average return of the funds in its Morningstar peer group, Commodities Broad Basket Funds. In addition, the fund has outpaced both its benchmark and peers during the three-, five- and 10-year periods ended June 30, 2015. We believe these longer-term results underscore the value of our risk-managed approach, which seeks to limit the impact of downside risk during periods of weak market performance.

As the return of the benchmark would indicate, the past year was a very challenging time for the commodity markets. The headline story of the period was the sharp downturn in oil prices, which was brought about by a combination of elevated supply and weaker-than-expected demand. The selling wasn’t limited to oil, however, as base metals, precious metals and agricultural commodities all lost ground to varying degrees. This downturn was brought about, in part, by the continued sluggishness in the global economy and concerns of how slow growth may impact future demand. Additionally, demand from China continued to tail off from the levels of two to three years ago, a development with large implications for both metal- and energy-related commodities. The strength in the U.S. dollar also had a negative impact on commodities’ performance by making them more expensive in U.S. dollar terms.

Fund Performance

The fund gains exposure to commodities using commodity-linked swaps and futures, and the remaining portion of the portfolio is invested in a fixed-income strategy. In the fund’s fixed-income portfolio, we emphasize short-term, higher-quality bonds to manage volatility and interest-rate risk, but we also take on a modest degree of credit risk to capture excess yield.

We were able to cushion the impact of the downturn in commodity prices by virtue of our disciplined, three-pronged investment strategy. The fund’s approach consists of a tactical element, a relative value strategy and a "roll enhancement" strategy. All three strategies made positive contributions to performance during the past year.

Tactical strategy: This strategy allows us to shift the fund’s effective weighting to the broader commodity market from a low of 50% to a high of 100%. Quantitative momentum models determine the investment level of the portfolio. When the momentum trend in the market is stable or rising, we may maintain or increase the fund’s overall exposure to commodities. When the momentum trend in the market is negative and falling, we may reduce the fund’s overall exposure to commodities.

This aspect of our strategy, which is designed to mitigate the impact of potential downside risk in the commodities market, worked as intended during the past year. After entering the reporting period with a nearly full exposure to commodities, we scaled back to the minimum level of 50% early in the third calendar quarter. We maintained this positioning though the fourth quarter of 2014 and the first three months of this year, which significantly dampened the impact of the market’s substantial downturn during this interval.

"We remain focused on capturing commodities’ upside potential while striving to manage the impact of downside volatility."

The tactical strategy continued to make a positive contribution during the final three months of the reporting period. The fund’s quantitative model called for an increase in net exposure to 65% during the second calendar quarter of 2015, and we augmented this by moving the exposure to 85% on a tactical basis. This tactical call worked well and enabled the fund to capture a greater portion of the rally in commodities during late April and into May. The fund closed the period with an exposure of 77%.

Roll enhancement strategy: Commodity investing entails purchasing a contract to buy or sell a specific commodity on a specific date. Since the fund does not want to take physical delivery of the underlying commodity contracts, we "roll" the contracts (i.e., sell one contract and purchase another) on a regular basis. Our roll enhancement strategy seeks to roll into contracts that maximize the fund’s return potential.

This strategy added value in the difficult market environment. We rotated the portfolio toward longer-dated contracts early in the reporting period and maintained that positioning throughout the year. This decision proved instrumental in cushioning some of the market’s downside risk, since front-month contracts (those scheduled to mature the soonest) typically bear the brunt of market downturns.

Relative value strategy: Our relative value strategy actively overweights or underweights each of the most liquid commodities depending on how "cheap" or "expensive" each commodity appears from a quantitative perspective. This portion of our strategy is based on the principle that commodity prices tend to "mean revert" over time. If the short-term, one-year moving average price of a commodity is above its long-term, five-year moving average price, we may underweight the commodity; if the short-term moving average price is below the long-term moving average price, we may overweight the commodity.

The relative value strategy made a positive contribution to performance, with an underweight in oil through the middle six months of the period having the largest impact on fund returns.

The fund's fixed-income strategy generated little in the way of excess performance during the past year. However, as designed, the fixed-income strategy generated enough income to fund the costs of trading in the commodity portion of the fund.

Outlook and Fund Positioning

While we anticipate that headline risk will continue to fuel near-term volatility in the commodity markets, we are also seeing an increasingly firm foundation for prices. The United States is experiencing healthy growth, the European Central Bank is aggressively enacting pro-inflationary policies and the Chinese government is pursuing a pro-growth agenda that is more targeted and efficient than those it has employed in the past. In combination, we believe these factors point to steady demand for commodities.

At the same time, lower prices have prompted producers to rationalize their operations across the commodities complex. In the energy sector, rig counts have declined and production growth has fallen well off of the levels of the past two years. Metals also stand to benefit from lower production due to a wave of consolidation among mining companies in recent years, and we see the potential for unusual weather patterns to disrupt supply in the agricultural space. Taken together, we believe these trends indicate that supplies across the commodities space have begun to move in line with demand, which should help support healthier performance for the market.

As always, we remain focused on capturing commodities’ upside potential while striving to manage the impact of downside volatility.

Terms to Know

Derivatives are contracts whose values can be based on a variety of instruments, including indices, currencies or securities. They can be utilized for a variety of reasons, including for hedging purposes, for risk management, for non-hedging purposes to seek to enhance potential gains, or as a substitute for direct investment in a particular asset class or to keep cash on hand to meet shareholder redemptions. Investing in derivatives entails special risks relating to liquidity, leverage and credit that may reduce returns and/or increase volatility.

A swap is an exchange of cash flows that are dependent on the price of an underlying commodity.

A structured note is a hybrid security whose return typically tracks the performance of an underlying debt obligation and a derivative that is embedded within it. The characteristics of the underlying debt obligation and derivative embedded within it adjust the securities risk/return profile.

Options are financial derivatives that offer the right, but not the obligation, to buy or sell a security or financial asset at an agreed-upon price and during a certain period of time or on a specific date.

Futures contracts are contractual agreements to buy or sell a particular commodity or financial instrument at a predetermined price in the future.

The unmanaged Bloomberg Commodity Index tracks a diversified group of commodities and commodities futures contracts traded on both U.S. and London exchanges. Index returns do not reflect fees or expenses and it is not possible to invest directly into an index.

The Morningstar Commodities Broad Basket Funds category consists of funds that invest in a diversified basket of commodity goods, including but not limited to, grains, minerals, metals, livestock, cotton, oils, sugar, coffee and cocoa. These funds may invest directly in physical assets or commodity-linked derivative instruments, such as commodity swap agreements.

Overweight means the fund holds a higher weighting in a given sector, security, or commodity than the benchmark. Underweight means the fund holds a lower weighting.

Mean reversion is a theory that prices and returns eventually move back toward the mean, or average.

Credit quality is a measure of a bond issuer’s ability to repay interest and principal in a timely manner. Rating agencies assign letter designations, such as AAA, AA and so forth. The lower the rating, the higher the probability of default.

Fair Value Measurements

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities.

The following is a summary of the inputs used as of June 30, 2015 in valuing the Fund's investments. For information on the Fund's policy regarding the valuation of investments, please refer to the Security Valuation section of Note A in the accompanying Notes to Consolidated Financial Statements.

During the year ended June 30, 2015, the amount of transfers between Level 2 and Level 3 was $2,001,758. The investments were transferred from Level 2 to Level 3 because of the lack of observable market data due to a decrease in market activity.

During the year ended June 30, 2015, the amount of transfers between Level 3 and Level 2 was $2,837,888. The investments were transferred from Level 3 to Level 2 due to the availability of a pricing source supported by observable inputs.

Transfers between price levels are recognized at the beginning of the reporting period.

(k) See Consolidated Investment Portfolio for additional detailed categorizations.

(l) Includes appreciation on unfunded loan commitments.

(m) Derivatives include unrealized appreciation (depreciation) on open futures contracts, commodity-linked swap contracts, interest rate swap contracts, and written options, at value.

Notes to Consolidated Financial Statements

A. Organization and Significant Accounting Policies

Deutsche Enhanced Commodity Strategy Fund (the "Fund'') is a diversified series of Deutsche Securities Trust (the "Trust"), which is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company organized as a Massachusetts business trust.

The Fund offers multiple classes of shares which provide investors with different purchase options. Class A shares are subject to an initial sales charge. Class B shares are closed to new purchases, except exchanges and the reinvestment of dividends or other distributions. Class B shares were not subject to an initial sales charge and are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions. Class B shares automatically convert to Class A shares six years after issuance. Class C shares are not subject to an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. Class C shares do not automatically convert into another class. Class S shares are not subject to initial or contingent deferred sales charges and are only available to a limited group of investors. Institutional Class shares are not subject to initial or contingent deferred sales charges and are generally available only to qualified institutions.

Investment income, realized and unrealized gains and losses, and certain fund-level expenses and expense reductions, if any, are borne pro rata on the basis of relative net assets by the holders of all classes of shares, except that each class bears certain expenses unique to that class such as distribution and service fees, services to shareholders and certain other class-specific expenses. Differences in class-level expenses may result in payment of different per share dividends by class. All shares of the Fund have equal rights with respect to voting subject to class-specific arrangements.

The Fund's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results could differ from those estimates. The policies described below are followed consistently by the Fund in the preparation of its consolidated financial statements.

Principles of Consolidation. The Fund invests indirectly in commodities markets through a wholly owned subsidiary, Cayman Commodity II, Ltd., organized under the laws of the Cayman Islands (the "Subsidiary"). Among other investments, the Subsidiary may invest in commodity-linked derivative instruments, such as swaps and futures. The Subsidiary may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiary's derivatives positions. The Subsidiary may also invest available cash in affiliated money market funds. The Subsidiary is managed by the same portfolio managers that manage the Fund. As of June 30, 2015, the Fund's investment in the Subsidiary was $183,518,364, representing 22.8% of the Fund's net assets. The Fund's Investment Portfolio has been consolidated and includes the portfolio holdings of the Fund and the Subsidiary.

The consolidated financial statements include the accounts of the Fund and the Subsidiary. All inter-company transactions and balances have been eliminated.

Security Valuation. Investments are stated at value determined as of the close of regular trading on the New York Stock Exchange on each day the exchange is open for trading.

Debt securities and loan participations and assignments are valued at prices supplied by independent pricing services approved by the Fund's Board. Such services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, prepayment speeds and other data, as well as broker quotes. If the pricing services are unable to provide valuations, debt securities are valued at the average of the most recent reliable bid quotations or evaluated prices, as applicable, obtained from broker-dealers and loan participations and assignments are valued at the mean of the most recent bid and ask quotations or evaluated prices, as applicable, obtained from one or more broker-dealers. Certain securities may be valued on the basis of a price provided by a single source or broker-dealer. No active trading market may exist for some senior loans and they may be subject to restrictions on resale. The inability to dispose of senior loans in a timely fashion could result in losses. These securities are generally categorized as Level 2.

Investments in open-end investment companies are valued at their net asset value each business day and are categorized as Level 1.

Futures contracts are generally valued at the settlement prices established each day on the exchange on which they are traded and are categorized as Level 1.

Swap contracts are valued daily based upon prices supplied by a Board approved pricing vendor, if available, and otherwise are valued at the price provided by the broker-dealer. Swap contracts are generally categorized as Level 2.

Exchange-traded options are valued at the last sale price or, in the absence of a sale, the mean between the closing bid and asked prices or at the most recent asked price (bid for purchased options) if no bid or asked price are available. Exchange-traded options are generally categorized as Level 1. Over-the-counter written or purchased options are valued at prices supplied by a Board approved pricing vendor, if available, and otherwise are valued at the price provided by the broker-dealer with which the option was traded. Over-the-counter written or purchased options are generally categorized as Level 2.

Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Board and are generally categorized as Level 3. In accordance with the Fund's valuation procedures, factors considered in determining value may include, but are not limited to, the type of the security; the size of the holding; the initial cost of the security; the existence of any contractual restrictions on the security's disposition; the price and extent of public trading in similar securities of the issuer or of comparable companies; quotations or evaluated prices from broker-dealers and/or pricing services; information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities); an analysis of the company's or issuer's financial statements; an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold; and with respect to debt securities, the maturity, coupon, creditworthiness, currency denomination and the movement of the market in which the security is normally traded. The value determined under these procedures may differ from published values for the same securities.

Disclosure about the classification of fair value measurements is included in a table following the Fund's Consolidated Investment Portfolio.

Securities Lending. Brown Brothers Harriman & Co., as lending agent, lends securities of the Fund to certain financial institutions under the terms of the Security Lending Agreement. The Fund retains benefits of owning the securities it has loaned and continues to receive interest and dividends generated by the securities and to participate in any changes in their market value. The Fund requires the borrowers of the securities to maintain collateral with the Fund consisting of either cash or liquid, unencumbered assets having a value at least equal to the value of the securities loaned. When the collateral falls below specified amounts, the lending agent will use its best efforts to obtain additional collateral on the next business day to meet required amounts under the security lending agreement. The Fund may invest the cash collateral into a joint trading account in an affiliated money market fund pursuant to Exemptive Orders issued by the SEC. The Fund receives compensation for lending its securities either in the form of fees or by earning interest on invested cash collateral net of borrower rebates and fees paid to a lending agent. Either the Fund or the borrower may terminate the loan. There may be risks of delay and costs in recovery of securities or even loss of rights in the collateral should the borrower of the securities fail financially. If the Fund is not able to recover securities lent, the Fund may sell the collateral and purchase a replacement investment in the market, incurring the risk that the value of the replacement security is greater than the value of the collateral. The Fund is also subject to all investment risks associated with the reinvestment of any cash collateral received, including, but not limited to, interest rate, credit and liquidity risk associated with such investments.

As of June 30, 2015, the Fund had securities on loan. The value of the related collateral exceeded the value of the securities loaned at period end.

When-Issued/Delayed Delivery Securities. The Fund may purchase or sell securities with delivery or payment to occur at a later date beyond the normal settlement period. At the time the Fund enters into a commitment to purchase or sell a security, the transaction is recorded and the value of the transaction is reflected in the net asset value. The price of such security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. At the time the Fund enters into a purchase transaction it is required to segregate cash or other liquid assets at least equal to the amount of the commitment. Additionally, the Fund may be required to post securities and/or cash collateral in accordance with the terms of the commitment.

Certain risks may arise upon entering into when-issued or delayed delivery transactions from the potential inability of counterparties to meet the terms of their contracts or if the issuer does not issue the securities due to political, economic, or other factors. Additionally, losses may arise due to changes in the value of the underlying securities.

Loan Participations and Assignments. Loan Participations and Assignments are portions of loans originated by banks and sold in pieces to investors. These floating rate loans ("Loans") in which the Fund invests, are arranged between the borrower and one or more financial institutions ("Lenders"). These Loans may take the form of Senior Loans, which are corporate obligations often issued in connection with recapitalizations, acquisitions, leveraged buy-outs and refinancing. The Fund invests in such Loans in the form of participations in Loans ("Participations") or assignments of all or a portion of Loans from third parties ("Assignments"). Participations typically result in the Fund having a contractual relationship only with the Lender, not with the borrower. The Fund has the right to receive payments of principal, interest and any fees to which it is entitled from the Lender selling the Participation and only upon receipt by the Lender of the payments from the borrower. In connection with purchasing Participations, the Fund generally has no right to enforce compliance by the borrower with the terms of the loan agreement relating to the Loan, or any rights of set-off against the borrower, and the Fund will not benefit directly from any collateral supporting the Loan in which it has purchased the Participation. As a result, the Fund assumes the credit risk of both the borrower and the Lender that is selling the Participation. Assignments typically result in the Fund having a direct contractual relationship with the borrower, and the Fund may enforce compliance by the borrower with the terms of the loan agreement. Loans held by the Fund are generally in the form of Assignments but the Fund may also invest in Participations. All Loans involve interest rate risk, liquidity risk and credit risk, including the potential default or insolvency of the borrower.

Federal Income Taxes. The Fund's policy is to comply with the requirements of the Internal Revenue Code, as amended, which are applicable to regulated investment companies and to distribute all of its taxable income to its shareholders.

Income from certain commodity-linked derivatives does not constitute "qualifying income" to the Fund. Receipt of such income could cause the Fund to be subject to tax at the Fund level. The IRS has issued a private letter ruling to the Fund stating that such income earned through its wholly-owned Subsidiary constitutes qualifying income. The Fund is required to increase its taxable income by its share of the Subsidiary's income, including net gains from commodity-linked transactions. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income for future periods.

Under the Regulated Investment Company Modernization Act of 2010, net capital losses incurred post-enactment may be carried forward indefinitely, and their character is retained as short-term and/or long-term. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

At June 30, 2015, the Fund had net tax basis capital loss carryforwards of approximately $216,092,000, including $194,919,000 of pre-enactment losses, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until June 30, 2016 ($6,708,000), June 30, 2017 ($102,120,000), June 30, 2018 ($77,996,000) and June 30, 2019 ($8,095,000), the respective expiration dates, whichever occurs first; and approximately $21,173,000 of post-enactment short-term losses, which may be applied against realized net taxable capital gains indefinitely.

The Fund has reviewed the tax positions for the open tax years as of June 30, 2015 and has determined that no provision for income tax and/or uncertain tax provisions is required in the Fund's consolidated financial statements. The Fund's federal tax returns for the prior three fiscal years remain open subject to examination by the Internal Revenue Service.

Distribution of Income and Gains. Distributions from net investment income of the Fund, if any, are declared and distributed to shareholders quarterly. Net realized gains from investment transactions, in excess of available capital loss carryforwards, would be taxable to the Fund if not distributed and, therefore, will be distributed to shareholders at least annually. The Fund may also make additional distributions for tax purposes if necessary.

The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to investments in futures and swap contracts and investment in the Subsidiary. As a result, net investment income (loss) and net realized gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. Accordingly, the Fund may periodically make reclassifications among certain of its capital accounts without impacting the net asset value of the Fund.

At June 30, 2015, the Fund's components of distributable earnings (accumulated losses) on a tax basis were as follows:

Undistributed ordinary income	$	1,588,627
Capital loss carryforward	$	(216,092,000	)
Unrealized appreciation (depreciation) on investments	$	508,611

In addition, the tax character of distributions paid to shareholders by the Fund is summarized as follows:

	Years Ended June 30,
	2015		2014
Distributions from ordinary income*	$	22,075,960	$	1,147,042

* For tax purposes, short-term capital gain distributions, and income and net realized gains from certain commodity-linked derivative instruments are considered ordinary income distributions.

Redemption Fees. The Fund imposes a redemption fee of 2% of the total redemption amount on Fund shares redeemed or exchanged within 15 days of buying them, either by purchase or exchange (subject to certain exceptions). This fee is assessed and retained by the Fund for the benefit of the remaining shareholders. The redemption fee is accounted for as an addition to paid-in capital.

Expenses. Expenses of the Trust arising in connection with a specific fund are allocated to that fund. Other Trust expenses which cannot be directly attributed to a fund are apportioned among the funds in the Trust based upon the relative net assets or other appropriate measures.

Contingencies. In the normal course of business, the Fund may enter into contracts with service providers that contain general 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 been made. However, based on experience, the Fund expects the risk of loss to be remote.

Other. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is recorded on the accrual basis. Realized gains and losses from investment transactions are recorded on an identified cost basis. Proceeds from litigation payments, if any, are included in net realized gain (loss) from investments. All discounts and premiums are accreted/amortized for both tax and financial reporting purposes.

B. Derivative Instruments

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on the notional amount of the swap. A bilateral swap is a transaction between the fund and a counterparty where cash flows are exchanged between the two parties. A centrally cleared swap is a transaction executed between the fund and a counterparty, then cleared by a clearing member through a central clearinghouse. The central clearinghouse serves as the counterparty, with whom the fund exchanges cash flows.

The value of a swap is adjusted daily, and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Consolidated Statement of Assets and Liabilities. Gains or losses are realized when the swap expires or is closed. Certain risks may arise when entering into swap transactions including counterparty default; liquidity; or unfavorable changes in interest rates or the value of the underlying reference security, commodity or index. In connection with bilateral swaps, securities and/or cash may be identified as collateral in accordance with the terms of the swap agreement to provide assets of value and recourse in the event of default. The maximum counterparty credit risk is the net present value of the cash flows to be received from or paid to the counterparty over the term of the swap, to the extent that this amount is beneficial to the Fund, in addition to any related collateral posted to the counterparty by the Fund. This risk may be partially reduced by a master netting arrangement between the Fund and the counterparty. Upon entering into a centrally cleared swap, the Fund is required to deposit with a financial intermediary cash or securities ("initial margin") in an amount equal to a certain percentage of the notional amount of the swap. Subsequent payments ("variation margin") are made or received by the Fund dependent upon the daily fluctuations in the value of the swap. In a cleared swap transaction, counterparty risk is minimized as the central clearinghouse acts as the counterparty.

Interest Rate Swaps. Interest rate swaps are agreements in which the Fund agrees to pay to the counterparty a fixed rate payment in exchange for the counterparty agreeing to pay to the Fund a variable rate payment, or the Fund agrees to receive from the counterparty a fixed rate payment in exchange for the counterparty agreeing to receive from the Fund a variable rate payment. The payment obligations are based on the notional amount of the swap. For the year ended June 30, 2015, the Fund entered into interest rate swap agreements to gain exposure to different parts of the yield curve while managing overall duration.

A summary of the open interest rate swap contracts as of the year ended June 30, 2015 is included in a table following the Fund's Consolidated Investment Portfolio. For the year ended June 30, 2015, the investment in interest rate swap contracts had a total notional amount generally indicative of a range from $190,000,000 to $250,000,000.

Commodity-Linked Swaps. Commodity-linked swap agreements involve a commitment to pay interest in exchange for a commodity-linked return based on a notional amount. To the extent the return of the reference commodity or commodity index underlying the commodity-linked swap exceeds or falls short of the offsetting interest rate obligation, the Fund will receive a payment or make a payment to the counterparty, respectively. For the year ended June 30, 2015, the Fund entered into commodity-linked swap agreements to gain exposure to the investment return of assets that trade in the commodity markets, without investing directly in physical commodities.

A summary of the open commodity-linked swap contracts as of June 30, 2015 is included in a table following the Fund's Consolidated Investment Portfolio. For the year ended June 30, 2015, the investment in long commodity-linked swap contracts had a total notional amount generally indicative of a range from $739,380,000 to $976,940,000, and the investment in short commodity-linked swap contracts had a total notional value generally indicative of a range from $0 to $193,100,000.

Options. An option contract is a contract in which the writer (seller) of the option grants the buyer of the option, upon payment of a premium, the right to purchase from (call option), or sell to (put option), the writer a designated instrument at a specified price within a specified period of time. The Fund may write or purchase interest rate swaption agreements which are options to enter into a pre-defined swap agreement. The interest rate swaption agreement will specify whether the buyer of the swaption will be a fixed-rate receiver or a fixed-rate payer upon exercise. Certain options, including options on indices, will require cash settlement by the Fund if exercised. For the year ended June 30, 2015, the Fund entered into options on interest rate swaps in order to hedge against potential adverse interest rate movements of portfolio assets and options on commodity futures contracts to gain exposure to the investment return of assets that trade in the commodity markets, without investing directly in physical commodities.

If the Fund writes a covered call option, the Fund foregoes, in exchange for the premium, the opportunity to profit during the option period from an increase in the market value of the underlying security above the exercise price. If the Fund writes a put option it accepts the risk of a decline in the value of the underlying security below the exercise price. Over-the-counter options have the risk of the potential inability of counterparties to meet the terms of their contracts. The Fund's maximum exposure to purchased options is limited to the premium initially paid. In addition, certain risks may arise upon entering into option contracts including the risk that an illiquid secondary market will limit the Fund's ability to close out an option contract prior to the expiration date and that a change in the value of the option contract may not correlate exactly with changes in the value of the securities or currencies hedged.

There were no open purchased option contracts as of June 30, 2015. A summary of open written option contracts is included in the table following the Fund's Investment Portfolio. For the year ended June 30, 2015, the investment in written option contracts had a total value generally indicative of a range from approximately $2,000 to $320,000, and purchased option contracts had a total value generally indicative of a range from $0 to approximately $174,000.

Futures Contracts. A futures contract is an agreement between a buyer or seller and an established futures exchange or its clearinghouse in which the buyer or seller agrees to take or make a delivery of a specific amount of a financial instrument at a specified price on a specific date (settlement date). For the year ended June 30, 2015, the Fund entered into commodity futures contracts to gain exposure to the investment return of assets that trade in the commodity markets, without investing directly in physical commodities and interest rate futures contracts to gain exposure to different parts of the yield curve while managing overall duration.

Upon entering into a futures contract, the Fund is required to deposit with a financial intermediary cash or securities ("initial margin") in an amount equal to a certain percentage of the face value indicated in the futures contract. Subsequent payments ("variation margin") are made or received by the Fund dependent upon the daily fluctuations in the value and are recorded for financial reporting purposes as unrealized gains or losses by the Fund. Gains or losses are realized when the contract expires or is closed. Since all futures contracts are exchange traded, counterparty risk is minimized as the exchange's clearinghouse acts as the counterparty, and guarantees the futures against default.

Certain risks may arise upon entering into futures contracts, including the risk that an illiquid market will limit the Fund's ability to close out a futures contract prior to the settlement date and the risk that the futures contract is not well correlated with the security, index or currency to which it relates. Risk of loss may exceed amounts disclosed in the Consolidated Statement of Assets and Liabilities.

A summary of the open futures contracts as of June 30, 2015 is included in the table following the Fund's Consolidated Investment Portfolio. For the year ended June 30, 2015, the investment in futures contracts purchased had a total notional value generally indicative of a range from approximately $59,515,000 to $114,928,000, and the investment in futures contracts sold had a total notional value generally indicative of a range from approximately $20,919,000 to $126,561,000.

D. Related Parties

Management Agreement. Under the Investment Management Agreement with Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the Advisor directs the investments of the Fund in accordance with its investment objectives, policies and restrictions. The Advisor determines the securities, instruments and other contracts relating to investments to be purchased, sold or entered into by the Fund.

Under the Investment Management Agreement with the Advisor, the Fund pays a monthly management fee based on the Fund's average daily net assets, computed and accrued daily and payable monthly, at the following annual rates:

First $500 million of the Fund's average daily net assets	.950	%
Next $500 million of such net assets	.900	%
Next $500 million of such net assets	.850	%
Over $1.5 billion of such net assets	.825	%

Accordingly, for the year ended June 30, 2015, the fee pursuant to the Investment Management Agreement was equivalent to an annual rate (exclusive of any applicable waivers/reimbursements) of 0.94% of the Fund's average daily net assets.

For the period from July 1, 2014 through September 30, 2014, the Advisor had contractually agreed to waive all or a portion of its fees and/or reimburse certain operating expenses of the Fund to the extent necessary to maintain the total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) of each class as follows:

("DDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.75% of average daily net assets of each of Class B and C shares. In accordance with the Fund's Underwriting and Distribution Services Agreement, DDI enters into related selling group agreements with various firms at various rates for sales of Class B and C shares.

DDI in turn has various agreements with financial services firms that provide these services and pays these fees based upon the assets of shareholder accounts the firms service. For the year ended June 30, 2015, the Service Fee was as follows:

Service Fee	Total Aggregated		Unpaid at June 30, 2015		Annual Rate
Class A	$	294,187	$	74,881		.23	%
Class B		449		74		.24	%
Class C		90,796		20,033		.25	%
	$	385,432	$	94,988

Underwriting Agreement and Contingent Deferred Sales Charge. DDI is the principal underwriter for the Fund. Underwriting commissions paid in connection with the distribution of Class A shares for the year ended June 30, 2015 aggregated $422.

In addition, DDI receives any contingent deferred sales charge ("CDSC") from Class B share redemptions occurring within six years of purchase and Class C share redemptions occurring within one year of purchase. There is no such charge upon redemption of any share appreciation or reinvested dividends. The CDSC is based on declining rates ranging from 4% to 1% for Class B and 1% for Class C, of the value of the shares redeemed. For the year ended June 30, 2015, the CDSC for the Fund's Class B and C shares was $546 and $3,352, respectively. A deferred sales charge of up to 1% is assessed on certain redemptions of Class A shares. For the year ended June 30, 2015, DDI received $50 for Class A shares.

Typesetting and Filing Service Fees. Under an agreement with DIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Fund. For the year ended June 30, 2015, the amount charged to the Fund by DIMA included in the Consolidated Statement of Operations under "Reports to shareholders" aggregated $24,792, of which $10,164 is unpaid.

Trustees' Fees and Expenses. The Fund paid retainer fees to each Trustee not affiliated with the Advisor, plus specified amounts to the Board Chairperson and Vice Chairperson and to each committee Chairperson.

Affiliated Cash Management Vehicles. The Fund may invest uninvested cash balances in Central Cash Management Fund and Deutsche Variable NAV Money Fund, affiliated money market funds which are managed by the Advisor. Each affiliated money market fund seeks to provide a high level of current income consistent with liquidity and the preservation of capital. Each affiliated money market fund is managed in accordance with Rule 2a-7 under the 1940 Act, which governs the quality, maturity, diversity and liquidity of instruments in which a money market fund may invest. Central Cash Management Fund seeks to maintain a stable net asset value, and Deutsche Variable NAV Money Fund maintains a floating net asset value. The Fund indirectly bears its proportionate share of the expenses of each affiliated money market fund in which it invests. Central Cash Management Fund does not pay the Advisor an investment management fee. To the extent that Deutsche Variable NAV Money Fund pays an investment management fee to the Advisor, the Advisor will waive an amount of the investment management fee payable to the Advisor by the Fund equal to the amount of the investment management fee payable on the Fund's assets invested in Deutsche Variable NAV Money Fund.

E. Line of Credit

The Fund and other affiliated funds (the "Participants") share in a $400 million revolving credit facility provided by a syndication of banks. The Fund may borrow for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee which is allocated based on net assets, among each of the Participants. Interest is calculated at a rate per annum equal to the sum of the Federal Funds Rate plus 1.25 percent plus if the one-month LIBOR exceeds the Federal Funds Rate, the amount of such excess. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement. The Fund had no outstanding loans at June 30, 2015.

F. Investing in Commodities-Related Investments

The Fund invests in commodity-linked derivative instruments such as commodity-linked swaps, structured notes and futures contracts that are designed to provide exposure to the investment return of assets that trade in the commodity markets, without investing directly in physical commodities. The commodities-linked derivatives instruments in which the Fund invests are more volatile than many other types of securities and may subject the Fund to special risks that do not apply to all derivatives transactions. The value of a commodity-linked derivative investment generally is based upon the price movements of a physical commodity (such as energy, minerals, or agricultural products), a futures contract, swap or commodity index, or other economic variables based upon changes in the value of commodities or the commodities markets. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, changes in storage costs, embargoes, tariffs, policies of commodity cartels and international economic, political and regulatory developments. Also, a liquid secondary market may not exist for the types of commodity-linked derivative instruments the Fund buys, which may make it difficult for the Fund to sell them at an acceptable price.

I. Reverse Stock Split

On December 6, 2013, the Fund implemented a 1 for 5 reverse stock split for each class of shares of the Fund. The net effect of the reverse stock split was to decrease the number of outstanding shares and increase the net asset value per share by a proportionate amount for each class of shares of the Fund. The reverse stock split had no impact on the overall value of a shareholder's investment in the Fund. Capital share activity referenced in Note G (Share Transactions) and per share and net asset value data in the Consolidated Financial Highlights tables have been restated to reflect the reverse stock split.

Report of Independent Registered Public Accounting Firm

To the Trustees of Deutsche Securities Trust and Shareholders of Deutsche Enhanced Commodity Strategy Fund:

In our opinion, the accompanying consolidated statement of assets and liabilities, including the consolidated investment portfolio, and the related consolidated statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Deutsche Enhanced Commodity Strategy Fund (the "Fund") at June 30, 2015, and the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These consolidated financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at June 30, 2015 by correspondence with the custodian, brokers, agent banks and the application of alternative auditing procedures where confirmations had not been received, provide a reasonable basis for our opinion.

Information About Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include management fees, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and account maintenance fees, which are not shown in this section. The following tables are intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. In the most recent six-month period, Class A, B, C and S shares limited these expenses; had it not done so, expenses would have been higher. The example in the table is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period (January 1, 2015 to June 30, 2015).

The tables illustrate your Fund's expenses in two ways:

—Actual Fund Return. This helps you estimate the actual dollar amount of ongoing expenses (but not transaction costs) paid on a $1,000 investment in the Fund using the Fund's actual return during the period. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the "Expenses Paid per $1,000" line under the share class you hold.

—Hypothetical 5% Fund Return. This helps you to compare your Fund's ongoing expenses (but not transaction costs) with those of other mutual funds using the Fund's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical fund return may be found in the shareholder reports of other mutual funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expense of owning different funds. Subject to certain exceptions, an account maintenance fee of $20.00 assessed once per calendar year for Classes A, B, C and S shares may apply for accounts with balances less than $10,000. This fee is not included in these tables. If it was, the estimate of expenses paid for Classes A, B, C and S shares during the period would be higher, and account value during the period would be lower, by this amount.

Advisory Agreement Board Considerations and Fee Evaluation

The Board of Trustees approved the renewal of Deutsche Enhanced Commodity Strategy Fund’s investment management agreement (the "Agreement") with Deutsche Investment Management Americas Inc. ("DIMA") in September 2014.

In terms of the process that the Board followed prior to approving the Agreement, shareholders should know that:

— In September 2014, all of the Fund’s Trustees were independent of DIMA and its affiliates.

— The Trustees met frequently during the past year to discuss fund matters and dedicated a substantial amount of time to contract review matters. Over the course of several months, the Board’s Contract Committee, in coordination with the Board’s Equity Oversight Committee, reviewed comprehensive materials received from DIMA, independent third parties and independent counsel. These materials included an analysis of the Fund’s performance, fees and expenses, and profitability compiled by a fee consultant retained by the Fund’s Independent Trustees (the "Fee Consultant"). The Board also received extensive information throughout the year regarding performance of the Fund.

— The Independent Trustees regularly meet privately with counsel to discuss contract review and other matters. In addition, the Independent Trustees were advised by the Fee Consultant in the course of their review of the Fund’s contractual arrangements and considered a comprehensive report prepared by the Fee Consultant in connection with their deliberations.

— In connection with reviewing the Agreement, the Board also reviewed the terms of the Fund’s Rule 12b-1 plan, distribution agreement, administrative services agreement, transfer agency agreement and other material service agreements.

— Based on its evaluation of the information provided, the Contract Committee presented its findings and recommendations to the Board. The Board then reviewed the Contract Committee’s findings and recommendations.

In connection with the contract review process, the Contract Committee and the Board considered the factors discussed below, among others. The Board also considered that DIMA and its predecessors have managed the Fund since its inception, and the Board believes that a long-term relationship with a capable, conscientious advisor is in the best interests of the Fund. The Board considered, generally, that shareholders chose to invest or remain invested in the Fund knowing that DIMA managed the Fund. DIMA is part of Deutsche Bank AG ("DB"), a major global banking institution that is engaged in a wide range of financial services. The Board believes that there are advantages to being part of a global asset management business that offers a wide range of investing expertise and resources, including hundreds of portfolio managers and analysts with research capabilities in many countries throughout the world.

As part of the contract review process, the Board carefully considered the fees and expenses of each Deutsche fund overseen by the Board in light of the fund’s performance. In many cases, this led to the negotiation and implementation of expense caps. As part of these negotiations, the Board indicated that it would consider relaxing these caps in future years following sustained improvements in performance, among other considerations.

In 2012, DB combined its Asset Management (of which DIMA was a part) and Wealth Management divisions into a new Asset and Wealth Management ("AWM") division. DB has advised the Independent Trustees that the U.S. asset management business is a critical and integral part of DB, and that DB will continue to invest in AWM a significant portion of the savings it has realized by combining its Asset and Wealth Management divisions, including ongoing enhancements to AWM’s investment capabilities. DB also has confirmed its commitment to maintaining strong legal and compliance groups within the AWM division.

While shareholders may focus primarily on fund performance and fees, the Fund’s Board considers these and many other factors, including the quality and integrity of DIMA’s personnel and such other issues as back-office operations, fund valuations, and compliance policies and procedures.

Nature, Quality and Extent of Services. The Board considered the terms of the Agreement, including the scope of advisory services provided under the Agreement. The Board noted that, under the Agreement, DIMA provides portfolio management services to the Fund and that, pursuant to a separate administrative services agreement, DIMA provides administrative services to the Fund. The Board considered the experience and skills of senior management and investment personnel, the resources made available to such personnel, the ability of DIMA to attract and retain high-quality personnel, and the organizational depth and stability of DIMA. The Board reviewed the Fund’s performance over short-term and long-term periods and compared those returns to various agreed-upon performance measures, including a market index and a peer universe compiled by the Fee Consultant using information supplied by Morningstar Direct ("Morningstar"), an independent fund data service. The Board also noted that it has put into place a process of identifying "Focus Funds" (e.g., funds performing poorly relative to a peer universe), and receives more frequent reporting and information from DIMA regarding such funds, along with DIMA’s plans to address underperformance. The Board believes this process is an effective manner of identifying and addressing underperforming funds. Based on the information provided, the Board noted that for the one-, three- and five-year periods ended December 31, 2013, the Fund’s performance (Class A shares) was in the 2nd quartile, 3rd quartile and 1st quartile, respectively, of the applicable Morningstar universe (the 1st quartile being the best performers and the 4th quartile being the worst performers). The Board also observed that the Fund has outperformed its benchmark in each of the one-, three- and five-year periods ended December 31, 2013.

Fees and Expenses. The Board considered the Fund’s investment management fee schedule, operating expenses and total expense ratios, and comparative information provided by Lipper Inc. ("Lipper") and the Fee Consultant regarding investment management fee rates paid to other investment advisors by similar funds (1st quartile being the most favorable and 4th quartile being the least favorable). With respect to management fees paid to other investment advisors by similar funds, the Board noted that the contractual fee rates paid by the Fund, which include a 0.10% fee paid to DIMA under the Fund’s administrative services agreement, were higher than the median (3rd quartile) of the applicable Lipper peer group (based on Lipper data provided as of December 31, 2013). The Board noted that the Fund’s Class A shares total (net) operating expenses (excluding 12b-1 fees) were expected to be higher than the median (3rd quartile) of the applicable Lipper expense universe (based on Lipper data provided as of December 31, 2013, and analyzing Lipper expense universe Class A (net) expenses less any applicable 12b-1 fees) ("Lipper Universe Expenses"). The Board also reviewed data comparing each share class’s total (net) operating expenses to the applicable Lipper Universe Expenses. The Board also considered how the Fund’s total (net) operating expenses compared to the total (net) operating expenses of a more customized peer group selected by Lipper (based on such factors as asset size). The Board also noted that the expense limitations agreed to by DIMA helped to ensure that the Fund’s total (net) operating expenses would remain competitive. The Board considered the Fund’s management fee rate as compared to fees charged by DIMA to comparable funds and considered differences between the Fund and the comparable funds.

The information requested by the Board as part of its review of fees and expenses also included information about institutional accounts and funds offered primarily to European investors ("Deutsche Europe funds") managed by DIMA and its affiliates. The Board noted that DIMA indicated that it manages an institutional account comparable to the Fund, but does not manage any comparable Deutsche Europe funds. The Board took note of the differences in services provided to Deutsche U.S. mutual funds ("Deutsche Funds") as compared to institutional accounts and that such differences made comparison difficult.

The Board noted that, in connection with the 2011 contract renewal process, DIMA agreed to implement a new management fee breakpoint.

On the basis of the information provided, the Board concluded that management fees were reasonable and appropriate in light of the nature, quality and extent of services provided by DIMA.

Profitability. The Board reviewed detailed information regarding revenues received by DIMA under the Agreement. The Board considered the estimated costs and pre-tax profits realized by DIMA from advising the Deutsche Funds, as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability of DIMA and its affiliates with respect to all fund services in totality and by fund. The Board and the Fee Consultant reviewed DIMA’s methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by DIMA in connection with the management of the Fund were not unreasonable.

Economies of Scale. The Board considered whether there are economies of scale with respect to the management of the Fund and whether the Fund benefits from any economies of scale. The Board noted that the Fund’s management fee schedule includes fee breakpoints. The Board concluded that the Fund’s fee schedule represents an appropriate sharing between the Fund and DIMA of such economies of scale as may exist in the management of the Fund at current asset levels.

Other Benefits to DIMA and Its Affiliates. The Board also considered the character and amount of other incidental benefits received by DIMA and its affiliates, including any fees received by DIMA for administrative services provided to the Fund and any fees received by an affiliate of DIMA for distribution services. The Board also considered benefits to DIMA related to brokerage and soft-dollar allocations, including allocating brokerage to pay for research generated by parties other than the executing broker dealers, which pertain primarily to funds investing in equity securities, along with the incidental public relations benefits to DIMA related to Deutsche Funds advertising and cross-selling opportunities among DIMA products and services. The Board concluded that management fees were reasonable in light of these fallout benefits.

Compliance. The Board considered the significant attention and resources dedicated by DIMA to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of DIMA’s and the Fund’s chief compliance officer; (ii) the large number of DIMA compliance personnel; and (iii) the substantial commitment of resources by DIMA and its affiliates to compliance matters.

Based on all of the information considered and the conclusions reached, the Board unanimously determined that the continuation of the Agreement is in the best interests of the Fund. In making this determination, the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, certain of which were in executive session with only the Independent Trustees and counsel present. It is possible that individual Trustees may have weighed these factors differently in reaching their individual decisions to approve the continuation of the Agreement.
