We strongly believe in our investment process, the consistent results we seek to deliver, and the value we can add for our clients. OUR HISTORY: Delaware Investments traces its roots to an investment advisory firm founded in 1929. We quickly learned how important consistent performance was to our clients, particularly in tough times, and continued to apply those lessons when we launched our first mutual fund in 1938. Delaware has managed money through 75 years of market cycles, and our dedication to consistent performance over the long term endures to this day. OUR PRINCIPLES: CLIENTS FIRST We believe that placing clients' interests ahead of our own is always the right thing to do. We offer a focused lineup of products that is aligned with our core asset management competencies rather than with popular trends. Some of the largest pension plans, endowments and foundations have entrusted their investments to Delaware Investments. Our institutional heritage and expertise serve us well when crafting mutual funds and managed account portfolios for individual investors. PASSION FOR PERFORMANCE Our results-oriented culture puts investors first and begins with our passion for performance. We seek to deliver consistently superior returns over the long term, and to do it in every asset class. This means we look at three-year and five-year track records as starting points in seeking to deliver long-term outperformance. PEOPLE WE'RE PROUD OF We recognize that smart, accomplished people are a competitive advantage. Our research analysts add value to our investors' portfolios, just as our award-winning operations team adds value for shareholders. At Delaware Investments, we are more than just committed -- we are passionate about our mission. That culture of passion flows through everything we do. POWERED BY RESEARCH Whether it's credit research on a corporate bond or a company visit for a small-cap consumer growth name, our deep teams of sector experts eat, sleep and breathe fundamental research. We believe that fundamental research is the key to achieving consistently superior returns over the long term. STRENGTH IN PARTNERSHIP Delaware Investments is the financial engine of the Lincoln Financial Group(R) family. Like our parent company, we understand the power of partnerships in a knowledge-based industry.

Fixed income investors found themselves facing an unusual interest rate environment, as the shrinking difference between short-term and long-term interest rates produced a condition sometimes referred to by economists as a "flattening yield curve." This condition in the past has sometimes preceded a recession, although many economists have recently noted the limits of its predictive nature and voiced optimism about the economic outlook for 2006. January 31 marked not only the close of the six-month period for your Fund, but the end of Alan Greenspan's term as acting Chairman of the U.S. Federal Reserve. New Chairman Ben Bernanke takes over at a time when the Fed is deliberating about monetary policy and how much further to raise its short-term interest rate target in 2006. The past six months have underscored an important lesson: No one can accurately and consistently predict the course of financial markets or the direction of interest rates, and attempts to do so are very often counterproductive. I encourage you to work with your financial advisor to consider building a portfolio that's diversified across the major investment asset classes--stocks, bonds, and short-term reserves -- keeping the allocations appropriate for your personal circumstances and risk tolerance. It is our belief at Delaware Investments that a long-term perspective is always healthy, and we remind you that fixed income investment vehicles may serve to balance investments in stocks, which are historically more volatile. If you are interested in acquiring more information about creating a well-diversified investment plan, speak with your advisor or visit our Web site, which includes more information about our funds and several interactive tools that you might find useful. Thank you as always for entrusting your hard-earned dollars to Delaware Investments. Sincerely, /s/ Jude T. Driscoll Jude T.

(C)2006 Delaware Distributors, L.P. - -------------------------------------------------------------------------------- Delaware Corporate Bond Fund Delaware Extended Duration Bond Fund Disclosure For the Period August 1, 2005 to January 31, 2006 - -------------------------------------------------------------------------------- OF FUND EXPENSES As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. The following examples are intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The Examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period August 1, 2005 to January 31, 2006. Actual Expenses The first section of the tables shown, "Actual Fund Return," provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that 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 first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second section of the tables shown, "Hypothetical 5% Return," provides information about hypothetical account values and hypothetical expenses based on the Funds' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. Each Fund's actual expenses shown in the tables reflect fee waivers in effect. The expenses shown in each table assume reinvestment of all dividends and distributions.

These financial statements and the related notes pertain to the Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund (each referred to as a "Fund" or collectively as the "Funds"). The Trust is an open-end investment company. The Funds are considered diversified under the Investment Company Act of 1940, as amended. The Funds offer Class A, Class B, Class C, Class R and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. Class R and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to a limited group of investors. The investment objective of the Funds is to seek to provide investors with total return. 1. Significant Accounting Policies The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Funds. Security Valuation - Equity securities, except those traded on the Nasdaq Stock Markets, Inc. (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange (NYSE) on the valuation date. Securities traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If on a particular day an equity security does not trade, then the mean between the bid and asked prices will be used. Securities listed on a foreign exchange are valued at the last quoted sales price before the Fund is valued. U.S. government and agency securities are valued at the mean between the bid and asked prices. Other long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Forward foreign currency exchange contracts and forward foreign cross currency exchange contracts are valued at the mean between the bid and asked prices of the contracts and are marked-to-market daily. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Futures contracts are valued at the daily quoted settlement prices. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Funds' Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, or with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes - Each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting - Investment income and common expenses are allocated to the classes of the Fund on the basis of "settled shares" of each class in relation to the net assets of the Funds. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Funds on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Repurchase Agreements - Each Fund may invest in a pooled cash account along with other members of the Delaware Investments(R) Family of Funds pursuant to an exemptive order issued by the Securities and Exchange Commission. The aggregate daily balance of the pooled cash account is invested in repurchase agreements secured by obligations of the U.S. government. The respective collateral is held by each Fund's custodian bank until the maturity of the respective repurchase agreements. Each repurchase agreement is 102% collateralized. However, in the event of default or bankruptcy by the counterparty to the agreement, realization of the collateral may be subject to legal proceedings. Foreign Currency Transactions - Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar daily. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Funds isolate that portion of realized gains and losses on investments in debt securities which are due to changes in foreign exchange rates from that which are due to changes in market prices of debt securities. The Funds report certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, where such components are treated as ordinary income (loss) for federal income tax purposes. Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other - Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. Realized gains (losses) on paydowns of mortgage-and asset-backed securities are classified as interest income. Each Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. 2. Investment Management, Administration Agreements and Other Transactions with Affiliates In accordance with the terms of its respective investment management agreement, each Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee which is calculated based on each Fund's average daily net assets as follows: Delaware Delaware Corporate Extended Duration Bond Fund Bond Fund --------- ----------------- On the first $500 million 0.500% 0.550% On the next $500 million 0.475% 0.500% On the next $1.5 billion 0.450% 0.450% In excess of $2.5 billion 0.425% 0.425% DMC has contractually agreed to waive that portion, if any, of its management fee and reimburse each Fund to the extent necessary to ensure the annual operating expenses, exclusive of taxes, interest, brokerage commissions, distribution fees, certain insurance costs and extraordinary expenses, do not exceed 0.55% of average daily net assets for each Fund through November 30, 2006. 29 - -------------------------------------------------------------------------------- Delaware Corporate Bond Fund Notes Delaware Extended Duration Bond Fund - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 2. Investment Management, Administration Agreements and Other Transactions with Affiliates (continued) Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Each Fund pays DSC a monthly fee computed at the annual rate of 0.04% of the Fund's average net assets for accounting and administration services. The Funds pay DSC a monthly fee based on shareholder accounts for dividend disbursing and transfer agent services. Pursuant to a distribution agreement and distribution plan, each Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.30% of the average daily net assets of the Class A shares, 1.00% of the average daily net assets of the Class B and C shares and 0.60% of the average daily net assets of Class R shares. Institutional Class shares pay no distribution and service expenses. DDLP has contracted to waive distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class A shares from exceeding 0.25% of average daily net assets. DDLP has contracted to limit distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class R shares from exceeding 0.50% of average daily net assets. At January 31, 2006, each Fund had liabilities payable to affiliates as follows: Delaware Delaware Corporate Extended Duration Bond Fund Bond Fund --------- ----------------- Investment Management fee payable to DMC $ 111,570 $ 13,782 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 55,213 32,860 Distribution fee payable to DDLP 178,857 64,284 Other expenses payable to DMC and affiliates* 9,715 13,284 * DMC, as part of its administrative services, pays operating expenses on behalf of each Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. As provided in the investment management agreement, each Fund bears the cost of certain legal services expenses, including internal legal services provided to the Funds by DMC employees. For the six months ended January 31, 2006, the Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund were charged $14,905 and $5,198, respectively for internal legal services provided by DMC. For the six months ended January 31, 2006, DDLP earned commissions on sales of Class A shares for each Fund as follows: Delaware Delaware Corporate Extended Duration Bond Fund Bond Fund --------- ----------------- $ 34,885 $ 32,290 For the six months ended January 31, 2006, DDLP received gross contingent deferred sales charge commissions on redemption of each Fund's Class A, Class B, and Class C shares, respectively, and these commissions were entirely used to offset up-front commissions previously paid by DDLP to broker-dealer on sales of those shares.

Dividend and Distribution Information Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, gains (losses) on foreign currency transactions and net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the six months ended January 31, 2006 and the year ended July 31, 2005 was as follows: Delaware Corporate Delaware Extended Bond Fund Duration Bond Fund ---------------------------- -------------------------- Six Months Year Six Months Year Ended Ended Ended Ended 1/31/06* 7/31/05 1/31/06* 7/31/05 Ordinary income $ 11,811,148 $ 16,740,938 $ 4,426,881 $ 6,102,484 Long-term capital gain 1,108,860 985,235 688,411 1,443,554 ------------ ------------ ----------- ------------ Total $ 12,920,008 $ 17,726,173 $ 5,115,292 $ 7,546,038 ============ ============ =========== ============ * Tax information for the period ended January 31, 2006 is an estimate and the tax character of dividends and distributions may be redesignated at fiscal year end. As of January 31, 2006, the components of net assets are estimated since final tax characteristics cannot be determined until fiscal year end. As of January 31, 2006, the estimated components of net assets on a tax basis were as follows: Delaware Delaware Corporate Extended Duration Bond Fund Bond Fund ------------- ----------------- Shares of beneficial interest $ 447,373,072 $ 168,021,710 Capital loss carry forward (622,198) (808,041) Undistributed ordinary income 176,468 244,721 Post-October losses (1,959,787) (191,021) Post-October currency losses (153,307) (61,952) Unrealized appreciation on investments (4,335,862) (969,107) ------------- ----------------- Net Assets $ 440,478,386 $ 166,236,310 ============= ================= Post-October losses represent losses realized on investments and foreign currency transactions from November 1, 2005 through January 31, 2006 that, in accordance with federal income tax regulations, the Funds have elected to defer and treat as having arisen in the following fiscal year. The differences between book basis and tax basis components of the net assets are primarily attributable to tax deferral of losses on wash sales, mark-to-market on futures contracts, mark-to-market on foreign currency contracts, straddle deferrals and tax treatment of market discount and premium on debt instruments. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of gain (loss) on foreign currency transactions, dividends and distributions, market discount and premium on certain debt instruments and paydowns of mortgage- and asset-backed securities. Results of operations and net assets were not affected by these reclassifications. For the six months ended January 31, 2006, the Funds recorded an estimate of these differences since the final tax characteristics cannot be determined until fiscal year end.

Line of Credit Each Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $225,000,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Funds had no amounts outstanding as of January 31, 2006, or at any time during the period. 7. Foreign Exchange Contracts The Funds may enter into forward foreign currency exchange contracts and forward foreign cross currency exchange contracts as a way of managing foreign exchange rate risk. The Funds may enter into these contracts to fix the U.S. dollar value of a security that it has agreed to buy or sell for the period between the date the trade was entered into and the date the security is delivered and paid for. The Funds may also use these contracts to hedge the U.S. dollar value of securities it already owns that are denominated in foreign currencies. The change in market value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. The use of forward foreign currency exchange contracts and forward foreign cross currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although forward foreign currency exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. In addition, the Funds could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. 32 - -------------------------------------------------------------------------------- Delaware Corporate Bond Fund Notes Delaware Extended Duration Bond Fund - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 8. Futures Contracts Each Fund may invest in financial futures contracts to hedge its existing portfolio securities against fluctuations in value caused by changes in prevailing market interest rates. Upon entering into a futures contract, the Fund deposits cash or pledges U.S. government securities to a broker, equal to the minimum "initial margin" requirements of the exchange on which the contract is traded. (In some cases, due to the form of the futures agreement, initial margin is held in a segregated account with the Fund's custodian, rather than directly with the broker). Subsequent payments are received from the broker or paid to the broker (or added to the segregated account) each day, based on the daily fluctuation in the market value of the contract. These receipts or payments are known as "variation margin" and are recorded daily by each Fund as unrealized gains or losses until the contracts are closed. When the contracts are closed, each Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risk of entering into futures contracts include potential imperfect correlation between the futures contracts and the underlying securities and the possibility of an illiquid secondary market for these instruments. The unrealized gain (loss) is included in liabilities net of receivables and other assets. 9. Credit and Market Risk Each Fund may invest in high yield fixed income securities, which carry ratings of BB or lower by Standard and Poor's Rating Group and/or Ba or lower by Moody's Investor Services, Inc. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities. Each Fund invests in fixed income securities whose value is derived from an underlying pool of mortgages or consumer loans. Investors receive principal and interest payments as the underlying mortgages and consumer loans are paid back. Some of these securities are collateralized mortgage obligations (CMOs). CMOs are debt securities issued by U.S. government agencies or by financial institutions and other mortgage lenders, which are collateralized by a pool of mortgages held under an indenture. Prepayment of mortgages may shorten the stated maturity of the obligation and can result in a loss of premium, if any has been paid. Certain of these securities may be stripped (securities, which provide only the principal or interest feature of the underlying security). The yield to maturity on an interest-only CMO is extremely sensitive not only to changes in prevailing interest rates, but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets. A rapid rate of principal payments may have a material adverse effect on each Fund's yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, each Fund may fail to fully recoup its initial investment in these securities even if the securities are rated in the highest rating categories. Each Fund may invest up to 15% of its total assets in illiquid securities which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Fund's Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. Rule 144A and illiquid securities have been denoted on the Statement of Net Assets. 10. Contractual Obligations The Funds enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these contracts. Management has reviewed the Funds' existing contracts and expects the risk of loss to be remote. 33 - -------------------------------------------------------------------------------- About - -------------------------------------------------------------------------------- THE ORGANIZATION This semiannual report is for the information of Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund and the Delaware Investments(R) Performance Update for the most recently completed calendar quarter.

THIS PAGE IS NOT PART OF THE SEMIANNUAL REPORT. ii - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- DEAR SHAREHOLDER: February 7, 2006 In the six months ended January 31, 2006, investors received mixed signals about the direction of the U.S. economy, which during the period was absorbing the effects of hurricanes Rita and Katrina. Fixed income investors found themselves facing an unusual interest rate environment, as the shrinking difference between short-term and long-term interest rates produced a condition sometimes referred to by economists as a "flattening yield curve." This condition in the past has sometimes preceded a recession, although many economists have recently noted the limits of its predictive nature and voiced optimism about the economic outlook for 2006. January 31 marked not only the close of the six-month period for your Fund, but the end of Alan Greenspan's term as acting Chairman of the U.S. Federal Reserve. New Chairman Ben Bernanke takes over at a time when the Fed is deliberating about monetary policy and how much further to raise its short-term interest rate target in 2006. The past six months have underscored an important lesson: No one can accurately and consistently predict the course of financial markets or the direction of interest rates, and attempts to do so are very often counterproductive. I encourage you to work with your financial advisor to consider building a portfolio that's diversified across the major investment asset classes -- stocks, bonds, and short-term reserves -- keeping the allocations appropriate for your personal circumstances and risk tolerance. It is our belief at Delaware Investments that a long-term perspective is always healthy, and we remind you that fixed income investment vehicles may serve to balance investments in stocks, which are historically more volatile. If you are interested in acquiring more information about creating a well-diversified investment plan, speak with your advisor or visit our Web site, which includes more information about our funds and several interactive tools that you might find useful. Thank you as always for entrusting your hard-earned dollars to Delaware Investments. Sincerely, /s/ Jude T. Driscoll Jude T.

Mutual fund advisory services provided by Delaware Management Company, a series of Delaware Management Business Trust, which is a registered investment advisor. (C)2006 Delaware Distributors, L.P. - -------------------------------------------------------------------------------- Disclosure For the Period August 1, 2005 to January 31, 2006 - -------------------------------------------------------------------------------- OF FUND EXPENSES As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period August 1, 2005 to January 31, 2006. Actual Expenses The first section of the table shown, "Actual Fund Return," provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that 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 first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second section of the table shown, "Hypothetical 5% Return," provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

See accompanying notes 12 - -------------------------------------------------------------------------------- Delaware Delchester Fund Notes January 31, 2006 (Unaudited) - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS Delaware Group Income Funds (the "Trust") is organized as a Delaware statutory trust and offers four series: Delaware Corporate Bond Fund, Delaware Delchester Fund, Delaware Extended Duration Bond Fund and Delaware High-Yield Opportunities Fund. These financial statements and the related notes pertain to Delaware Delchester Fund (the "Fund"). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended, and offers Class A, Class B, Class C, Class R, and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. Class R and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to a limited group of investors. As of January 31, 2006, Class R has not commenced operations. The investment objective of the Fund is to seek total return, and as a secondary objective, high current income. 1. Significant Accounting Policies The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Fund. Security Valuation -- Equity securities, except those traded on the Nasdaq Stock Market, Inc. (Nasdaq), are valued at the last quoted sales price as of the time of regular close of the New York Stock Exchange (NYSE) on the valuation date. Securities traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If on a particular day an equity security does not trade, then the mean between the bid and asked prices will be used. Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Securities lending collateral is valued at amortized cost, which approximates market value. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Fund's Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, or with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes -- The Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting -- Investment income and common expenses are allocated to the classes of the Fund on the basis of "settled shares" of each class in relation to the net assets of the Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Repurchase Agreements -- The Fund may invest in a pooled cash account along with other members of the Delaware Investments(R) Family of Funds pursuant to an exemptive order issued by the Securities and Exchange Commission. The aggregate daily balance of the pooled cash account is invested in repurchase agreements secured by obligations of the U.S government. The respective collateral is held by the Fund's custodian bank until the maturity of the respective repurchase agreements. Each repurchase agreement is 102% collateralized. However, in the event of default or bankruptcy by the counterparty to the agreement, realization of the collateral may be subject to legal proceedings. Use of Estimates -- The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other -- Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. Realized gains (losses) on paydowns of mortgage-and asset-backed securities are classified as interest income. The Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. The Fund may receive earnings credits from its custodian when positive cash balances are maintained, which are used to offset custody fees. There were no earnings credits for the six months ended January 31, 2006. 2. Investment Management, Administration Agreements and Other Transactions with Affiliates In accordance with the terms of its investment management agreement, the Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the Investment Manager, an annual fee which is calculated daily at the rate of 0.65% on the first $500 million of average daily net assets of the Fund, 0.60% on the next $500 million, 0.55% on the next $1.5 billion and 0.50% on average daily net assets in excess of $2.5 billion. DMC has contractually agreed to waive that portion, if any, of its management fee and reimburse the Fund to the extent necessary to ensure that annual operating expenses, exclusive of taxes, interest, brokerage commissions, distribution fees, certain insurance costs and extraordinary expenses, do not exceed 0.91% of average daily net assets until November 30, 2006. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. The Fund pays DSC a monthly fee computed at the annual rate of 0.04% of the Fund's average daily net assets for accounting and administration services. The Fund pays DSC a monthly fee based on the number of shareholder accounts for dividend disbursing and transfer agent services. 13 - -------------------------------------------------------------------------------- Delaware Delchester Fund Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 2. Investment Management, Administration Agreements and Other Transactions with Affiliates (continued) Pursuant to a distribution agreement and distribution plan, the Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.30% of the average daily net assets of the Class A shares, 1.00% of the average daily net assets of the Class B and C shares, and 0.60% of the average daily net assets of Class R shares. Effective August 1, 2005, DDLP has contracted to limit distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class R shares from exceeding 0.50% of average daily net assets. Institutional Class shares pay no distribution and service expenses. The Board of Trustees has adopted a formula for calculating 12b-1 plan fees for the Fund's Class A shares that went into effect on June 1, 1992. The total 12b-1 fees to be paid by Class A shareholders of the Fund will be the sum of 0.10% of the average daily net assets representing shares that were acquired prior to June 1, 1992 and 0.30% of the average daily net assets representing shares that were acquired on or after June 1, 1992. All Class A shareholders will bear 12b-1 fees at the same rate, the blended rate based upon the allocation of the 0.10% and 0.30% rates described above. At January 31, 2006, the Fund had liabilities payable to affiliates as follows: Investment management fees payable to DMC $150,481 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 70,687 Distribution fee payable to DDLP 102,455 Other expenses payable to DMC and affiliates* 7,470 * DMC, as part of its administrative services, pays operating expenses on behalf of the Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. As provided in the investment management agreement, the Fund bears the cost of certain legal services expenses, including internal legal services provided to the Fund by DMC employees. For the six months ended January 31, 2006, the cost for internal legal services provided by DMC was $10,859. For the six months ended January 31, 2006, DDLP earned $7,541 for commissions on sales of the Fund's Class A shares. For the six months ended January 31, 2006, DDLP received gross contingent deferred sales charge commissions of $419, $24,593 and $214 on redemption of the Fund's Class A, Class B and Class C shares, respectively, and these commissions were entirely used to offset up-front commissions previously paid by DDLP to broker-dealers on sales of those shares. Certain officers of DMC, DSC and DDLP are officers and/or trustees of the Trust. These officers and trustees are paid no compensation by the Fund. 3. Investments For the six months ended January 31, 2006, the Fund made purchases of $220,836,333 and sales of $252,691,400 of investment securities other than short-term investments. At January 31, 2006, the cost of investments for federal income tax purposes has been estimated since the final tax characteristics cannot be determined until fiscal year end. At January 31, 2006, the cost of investments was $372,448,767. At January 31, 2006, the net unrealized depreciation was $4,383,171, of which $9,519,890 related to unrealized appreciation of investments and $13,903,061 related to unrealized depreciation of investments. 4. Dividend and Distribution Information Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the six months ended January 31, 2006 and year ended July 31, 2005 was as follows: Six Months Year Ended Ended 1/31/06* 7/31/05 ----------- ----------- Ordinary income $11,784,232 $27,495,811 * Tax information for the period ended January 31, 2005 is an estimate and the tax character of dividends and distributions may be redesignated at fiscal year end. The components of net assets are estimated since final tax characteristics cannot be determined until fiscal year end. As of January 31, 2006, the estimated components of net assets on a tax basis were as follows: Shares of beneficial interest $ 944,871,930 Undistributed ordinary income 4,506 Capital loss carryforwards (638,109,336) Unrealized depreciation of investments (4,383,171) Net assets ------------- $ 302,383,929 ============= The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales and tax treatment of market discount and premium on debt instruments. For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. Capital loss carryforwards remaining at July 31, 2005 will expire as follows: $123,490,311 expires in 2008, $284,053,994 expires in 2009, $211,481,773 expires in 2010 and $20,031,318 expires in 2011. For the six months ended January 31, 2006, the Fund had capital gains of $948,060 which may reduce the capital loss carryforwards. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. For the six months ended January 31, 2006, the Fund recorded an estimate of these differences since final tax characteristics cannot be determined until fiscal year end. Reclassifications are primarily due to tax treatment of market discount and premium on certain debt instruments and paydowns of mortgage- and asset-backed securities. Results of operations and net assets were not affected by these reclassifications. Undistributed net investment income $ (64,006) Accumulated net realized loss 64,006 14 - -------------------------------------------------------------------------------- Delaware Delchester Fund Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 5.

The respective amounts are included in Class B redemptions and Class A subscriptions in the table above and the Statements of Changes in Net Assets. 6. Line of Credit The Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $225,000,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Fund had no amounts outstanding as of January 31, 2006, or at any time during the period. 7. Securities Lending The Fund, along with other funds in the Delaware Investments(R) Family of Funds, may lend its securities pursuant to a security lending agreement (Lending Agreement) with JP Morgan Chase. Initial security loans made pursuant to the Lending Agreement are required to be secured by U.S. government obligations and/or cash collateral not less than 102% of the market value of the securities issued in the United States. With respect to each loan, if the aggregate market value of the collateral held on any business day is less than the aggregate market value of the securities which are the subject of such loan, the borrower will be notified to provide additional collateral not less than the applicable collateral requirements. Cash collateral received is invested in fixed-income securities, with a weighted average maturity not to exceed 90 days, rated in one of the top two tiers by Standard & Poor's Ratings Group or Moody's Investors Service, Inc. or repurchase agreements collateralized by such securities. However, in the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to the Fund, or at the discretion of the lending agent, replace the loaned securities. The Fund continues to record dividends on the securities loaned and is subject to change in value of the securities loaned that may occur during the term of the loan. The Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. The security lending agent and the borrower retain a portion of the earnings from the collateral investments. The Fund records security lending income net of such allocation. At January 31, 2006, the market value of securities on loan was $64,656,355, for which cash collateral was received and invested in accordance with the Lending Agreement. Such investments are presented on the Statement of Net Assets under the caption "Securities Lending Collateral". 8. Credit and Market Risk The Fund invests a portion of its assets in high yield fixed income securities, which carry ratings of BB or lower by Standard & Poor's Ratings Group and/or Ba or lower by Moody's Investors Service, Inc. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities. The Fund may invest up to 15% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. Rule 144A and illiquid securities have been identified on the Statement of Net Assets. 9. Contractual Obligations The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote. 15 - -------------------------------------------------------------------------------- About - -------------------------------------------------------------------------------- THE ORGANIZATION This semiannual report is for the information of Delaware Delchester Fund shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for Delaware Delchester Fund and the Delaware Investments(R) Performance Update for the most recently completed calendar quarter.

We strongly believe in our investment process, the consistent results we seek to deliver, and the value we can add for our clients. OUR HISTORY: Delaware Investments traces its roots to an investment advisory firm founded in 1929. We quickly learned how important consistent performance was to our clients, particularly in tough times, and continued to apply those lessons when we launched our first mutual fund in 1938. Delaware has managed money through 75 years of market cycles, and our dedication to consistent performance over the long term endures to this day. OUR PRINCIPLES: CLIENTS FIRST We believe that placing clients' interests ahead of our own is always the right thing to do. We offer a focused lineup of products that is aligned with our core asset management competencies rather than with popular trends. Some of the largest pension plans, endowments and foundations have entrusted their investments to Delaware Investments. Our institutional heritage and expertise serve us well when crafting mutual funds and managed account portfolios for individual investors. PASSION FOR PERFORMANCE Our results-oriented culture puts investors first and begins with our passion for performance. We seek to deliver consistently superior returns over the long term, and to do it in every asset class. This means we look at three-year and five-year track records as starting points in seeking to deliver long-term outperformance. PEOPLE WE'RE PROUD OF We recognize that smart, accomplished people are a competitive advantage. Our research analysts add value to our investors' portfolios, just as our award-winning operations team adds value for shareholders. At Delaware Investments, we are more than just committed -- we are passionate about our mission. That culture of passion flows through everything we do. POWERED BY RESEARCH Whether it's credit research on a corporate bond or a company visit for a small-cap consumer growth name, our deep teams of sector experts eat, sleep and breathe fundamental research. We believe that fundamental research is the key to achieving consistently superior returns over the long term. STRENGTH IN PARTNERSHIP Delaware Investments is the financial engine of the Lincoln Financial Group(R) family. Like our parent company, we understand the power of partnerships in a knowledge-based industry. We collaborate with a wide variety of financial services organizations to provide the very best in investment products and services. (C)2006 Delaware Distributors, L.P.

Fixed income investors found themselves facing an unusual interest rate environment, as the shrinking difference between short-term and long-term interest rates produced a condition sometimes referred to by economists as a "flattening yield curve." This condition in the past has sometimes preceded a recession, although many economists have recently noted the limits of its predictive nature and voiced optimism about the economic outlook for 2006. January 31 marked not only the close of the six-month period for your Fund, but the end of Alan Greenspan's term as acting Chairman of the U.S. Federal Reserve. New Chairman Ben Bernanke takes over at a time when the Fed is deliberating about monetary policy and how much further to raise its short-term interest rate target in 2006. The past six months have underscored an important lesson: No one can accurately and consistently predict the course of financial markets or the direction of interest rates, and attempts to do so are very often counterproductive. I encourage you to work with your financial advisor to consider building a portfolio that's diversified across the major investment asset classes -- stocks, bonds, and short-term reserves -- keeping the allocations appropriate for your personal circumstances and risk tolerance. It is our belief at Delaware Investments that a long-term perspective is always healthy, and we remind you that fixed income investment vehicles can serve to balance investments in stocks, which are historically more volatile. If you are interested in acquiring more information about creating a well-diversified investment plan, speak with your advisor or visit our Web site, which includes more information about our funds and several interactive tools that you might find useful. Thank you as always for entrusting your hard-earned dollars to Delaware Investments. Sincerely, /s/ Jude T. Driscoll Jude T.

Mutual fund advisory services provided by Delaware Management Company, a series of Delaware Management Business Trust, which is a registered investment advisor. (C)2006 Delaware Distributors, L.P. - -------------------------------------------------------------------------------- Disclosure For the Period August 1, 2005 to January 31, 2006 - -------------------------------------------------------------------------------- OF FUND EXPENSES As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period August 1, 2005 to January 31, 2006. Actual Expenses The first section of the table shown, "Actual Fund Return," provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that 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 first section under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The second section of the table shown, "Hypothetical 5% Return," provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund's actual expenses shown in the table reflect fee waivers in effect. The expenses shown in the table assume reinvestment of all dividends and distributions.

Total investment return reflects waivers and payment of fees by the manager. Performance would have been lower had the expense limitation not been in effect.

See accompanying notes 13 - -------------------------------------------------------------------------------- Delaware High-Yield Opportunities Fund Notes January 31, 2006 (Unaudited) - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS Delaware Group Income Funds (the "Trust") is organized as a Delaware statutory trust and offers four Fund: Delaware Corporate Bond Fund, Delaware Delchester Fund, Delaware Extended Duration Bond Fund and Delaware High-Yield Opportunities Fund. These financial statements and the related notes pertain to Delaware High-Yield Opportunities Fund (the "Fund"). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended, and offers Class A, Class B, Class C, Class R and Institutional Class shares. Class A shares are sold with a front-end sales charge of up to 4.50%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. Class R and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to a limited group of investors. The investment objective of the Fund is to seek total return, and as a secondary objective, high current income. 1. Significant Accounting Policies The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Fund. Security Valuation -- Equity securities, except those traded on the Nasdaq Stock Market, Inc. (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange (NYSE) on the valuation date. Securities traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If on a particular day an equity security does not trade, then the mean between the bid and asked prices will be used. Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Fund's Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, or with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes -- The Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting -- Investment income and common expenses are allocated to the classes of the Fund on the basis of "settled shares" of each class in relation to the net assets of the Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Repurchase Agreements -- The Fund may invest in a pooled cash account along with other members of the Delaware Investments(R) Family of Funds pursuant to an exemptive order issued by the Securities and Exchange Commission. The aggregate daily balance of the pooled cash account is invested in repurchase agreements secured by obligations of the U.S. government. The respective collateral is held by the Fund's custodian bank until the maturity of the respective repurchase agreements. Each repurchase agreement is 102% collateralized. However, in the event of default or bankruptcy by the counterparty to the agreement, realization of the collateral may be subject to legal proceedings. Use of Estimates -- The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other -- Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on the accrual basis. Discounts and premiums on non-convertible bonds are amortized to interest income over the lives of the respective securities. Realized gains (losses) on paydowns of mortgage- and asset-backed securities are classified as interest income. The Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. 2. Investment Management, Administration Agreements and Other Transactions with Affiliates In accordance with the terms of its investment management agreement, the Fund pays Delaware Management Company (DMC), a Fund of Delaware Management Business Trust and the investment manager, an annual fee which is calculated daily at the rate of 0.65% on the first $500 million of average daily net assets of the Fund, 0.60% on the next $500 million, 0.55% on the next $1.5 billion, and 0.50% on average daily net assets in excess of $2.5 billion. DMC has contractually agreed to waive that portion, if any, of its management fee and reimburse the Fund to the extent necessary to ensure that annual operating expenses, exclusive of taxes, interest, brokerage commissions, distribution fees, certain insurance costs and extraordinary expenses, do not exceed 0.83% of average daily net assets of the Fund through November 30, 2006. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. The Fund pays DSC a monthly fee computed at the annual rate of 0.04% of the Fund's average daily net assets, for accounting and administration services. The Fund pays DSC a monthly fee based on the number of shareholder accounts for dividend disbursing and transfer agent services. Pursuant to the distribution agreement and distribution plan, the Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.30% of the average daily net assets of the Class A shares, 1.00% of the average daily net assets of the Class B and C shares, and 0.60% of the average daily net assets of Class R shares. DDLP has contracted to limit distribution and service fees through November 30, 2006 in order to prevent distribution and service fees of Class R shares from exceeding 0.50% of average daily net assets. Institutional Class shares pay no distribution and service expenses. 14 - -------------------------------------------------------------------------------- Delaware High-Yield Opportunities Fund Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 2. Investment Management, Administration Agreements and Other Transactions with Affiliates (continued) At January 31, 2006, the Fund had liabilities payable to affiliates as follows Investment management fee payable to DMC $42,147 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 22,650 Distribution fee payable to DDLP 94,686 Other expenses payable to DMC and affiliates* 4,799 * DMC, as part of its administrative services, pays operating expenses on behalf of the Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. As provided in the investment management agreement, the Fund bears the cost of certain legal services expenses, including internal legal services provided to the Fund by DMC employees. For the six months ended January 31, 2006, the Fund was charged $4,309 for internal legal services provided by DMC. For the six months ended January 31, 2006, DDLP earned $14,890 for commissions on sales of the Fund's Class A shares. For the six months ended January 31, 2006, DDLP received gross contingent deferred sales charge commissions of $5,759, $32,914 and $4,419 on redemption of the Fund's Class A, Class B and Class C shares, respectively, and these commissions were entirely used to offset up-front commissions previously paid by DDLP to broker-dealers on sales of these shares. Certain officers of DMC, DSC and DDLP are officers and/or trustees of the Trust. These officers and trustees are paid no compensation by the Fund. 3. Investments For the six months ended January 31, 2006, the Fund made purchases of $97,000,944 and sales of $96,934,522 of investment securities other than short-term investments. At January 31, 2006, the cost of investments for federal income tax purposes has been estimated since the final tax characteristics cannot be determined until the fiscal year end. At January 31, 2006, the cost of investments was $119,941,289. At January 31, 2006, the net unrealized depreciation was $1,389,249, of which $2,750,675 related to unrealized appreciation of investments and $4,139,924 related to unrealized depreciation of investments. 4. Dividend and Distribution Information Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the six months ended January 31, 2006 and the year ended July 31, 2005 was as follows: Six Months Year Ended Ended 1/31/06* 7/31/05 ---------- ---------- Ordinary income $4,457,713 $7,239,281 * Tax information for the period ended January 31, 2006 is an estimate and the tax character of dividends and distributions may be redesignated at fiscal year end. The components of net assets are estimated since final tax characteristics cannot be determined until fiscal year end. As of January 31, 2006, the estimated components of net assets on a tax basis were as follows: Shares of beneficial interest $126,118,362 Other temporary differences (59) Capital loss carryforwards (4,163,479) Unrealized depreciation of investments (1,389,249) ------------ Net assets $120,565,575 ============ The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales and tax treatment of market discount and premium on debt instruments. For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount and premium on certain debt instruments and paydown gain (loss) on mortgage- and asset-backed securities. Results of operations and net assets were not affected by these reclassifications. For the six months ended January 31, 2006, the Fund recorded an estimate of these differences since the final tax characteristics cannot be determined until fiscal year end. Undistributed net investment income $ 178,115 Accumulated net realized gain (loss) (178,115) For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. Capital loss carryforwards outstanding at July 31, 2005 will expire as follows: $3,971,857 expires in 2010. For the six months ended January 31, 2006, the Fund had capital losses of $191,622, which may increase the capital loss carryforwards. 15 - -------------------------------------------------------------------------------- Delaware High-Yield Opportunities Fund Notes - -------------------------------------------------------------------------------- TO FINANCIAL STATEMENTS (CONTINUED) 5. Capital Shares Transactions in capital shares were as follows: Six Months Year Ended Ended 1/30/06 7/31/05 Shares sold: Class A 4,240,069 16,251,597 Class B 269,816 1,232,222 Class C 840,770 2,768,340 Class R 230,077 466,102 Institutional Class 962,360 1,566,148 Shares issued upon reinvestment of dividends and distributions: Class A 493,221 779,426 Class B 52,173 107,654 Class C 73,001 122,839 Class R 19,683 10,143 Institutional Class 54,858 55,865 ---------- ----------- 7,236,028 23,360,336 ---------- ----------- Shares repurchased: Class A (6,558,532) (8,568,072) Class B (661,750) (1,088,072) Class C (892,285) (983,589) Class R (70,678) (15,381) Institutional Class (30,171) (57,219) ---------- ----------- (8,213,416) (10,712,333) ---------- ----------- Net increase (decrease) (977,388) 12,648,003 ========== =========== For the six months ended January 31, 2006 and the year ended July 31, 2005, 40,587 Class B shares were converted to 40,587 Class A shares valued at $174,307 and 84,575 Class B shares were converted to 84,505 Class A shares valued at $368,395, respectively. The respective amounts are included in Class B redemptions and Class A subscriptions in the table above and the Statements of Changes in Net Assets. 6. Line of Credit The Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $225,000,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Fund had no amounts outstanding as of January 31, 2006, or at any time during the period. 7. Credit and Market Risks The Fund invests a portion of its assets in high yield fixed income securities, which carry ratings of BB or lower by Standard & Poor's Ratings Group and/or Ba or lower by Moody's Investors Service, Inc. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities. The Fund may invest up to 15% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Fund's Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. Rule 144A and illiquid securities have been identified on the Statement of Net Assets. 8. Contractual Obligations The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote. 16 - -------------------------------------------------------------------------------- About - -------------------------------------------------------------------------------- THE ORGANIZATION This semiannual report is for the information of Delaware High-Yield Opportunities Fund shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for Delaware High-Yield Opportunities Fund and the Delaware Investments(R) Performance Update for the most recently completed calendar quarter.
