Delaware Floating Rate Fund seeks high current income and, secondarily, long-term total return.
|
| What are the Fund’s fees and expenses?
|
The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Delaware Investments® Funds. More information about these and other discounts is available from your financial intermediary, in the Fund’s prospectus under the section entitled “About your account,” and in the Fund’s statement of additional information (SAI) under the section entitled “Purchasing Shares.”

| Example
|
| This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. In addition, the example shows expenses for Class C shares assuming those shares were not redeemed at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

| Portfolio turnover
|
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 90% of the average value of its portfolio. For the next fiscal year, the Fund generally expects to have a portfolio turnover rate over 100%.
|
| What are the Fund’s principal investment strategies?
|
| Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in floating rate loans and other floating rate debt securities (80% policy). Delaware Management Company (Manager) will determine how much of the Fund’s assets to allocate among the different types of securities in which the Fund may invest based on its evaluation of economic and market conditions and its assessment of the returns and potential for appreciation that can be achieved from various sectors of the fixed income market. The Fund’s investments may be variable- and floating-rate debt securities that generally pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). Derivatives instruments may be utilized to effectively convert the fixed-rate interest payments from a group of certain Fund portfolio securities into floating-rate interest payments. The average portfolio duration (that is, the sensitivity to general changes in interest rates) of this Fund will generally not exceed one year. Up to 100% of the Fund’s total assets may be allocated to below-investment-grade securities within the Fund. Investments in emerging markets will, in the aggregate, be limited to no more than 15% of the Fund’s total assets. The Manager will limit non-U.S.-dollar-denominated securities to no more than 50% of net assets, but total non-U.S.-dollar currency exposure will be limited, in the aggregate, to no more than 25% of net assets. The Fund may also invest up to 50% of its total assets in a wide range of derivatives instruments, including options, futures contracts, options on futures contracts, and swaps. In addition, the Fund may hold a portion of its assets in cash or cash equivalents. The 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change.
|
| What are the principal risks of investing in the Fund?
|
Investing in any mutual fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund’s portfolio. The Manager is an indirect wholly owned subsidiary of Macquarie Group Limited (MGL). Neither the Manager nor its affiliates referred to in this document are authorized deposit-taking institutions for the purposes of the Bank Act 1959 (Commonwealth of Australia). The obligations of these entities do not represent deposits or other liabilities of Macquarie Bank Limited (MBL), a subsidiary of MGL and an affiliate of the Manager. MBL does not guarantee or otherwise provide assurance in respect of the obligations of these entities, unless noted otherwise. The Fund is governed by U.S. laws and regulations. The Fund’s principal risks include: Market risk — The risk that all or a majority of the securities in a certain market — such as the stock or bond market — will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling. Credit risk — The risk that an issuer of a debt security, including a governmental issuer or an entity that insures a bond, may be unable to make interest payments and/or repay principal in a timely manner. Loans and other indebtedness risk — The risk that the portfolio will not receive payment of principal, interest, and other amounts due in connection with these investments and will depend primarily on the financial condition of the borrower and the lending institution. A portfolio’s ability to sell its loans or to realize their full value upon sale may also be impaired due to the lack of an active trading market, irregular trading activity, wide bid/ask spreads, contractual restrictions, and extended trade settlement periods. In addition, certain loans in which a fund invests may not be considered securities. A fund therefore may not be able to rely upon the anti-fraud provisions of the federal securities laws with respect to these investments. Interest rate risk — The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates. High yield (junk bond) risk — The risk that high yield securities, commonly known as “junk bonds,” are subject to reduced creditworthiness of issuers; increased risk of default and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than are higher-rated securities. High yield bonds are sometimes issued by municipalities that have less financial strength and therefore have less ability to make projected debt payments on the bonds. Adjustable rate securities risk — During periods of rising interest rates, because changes in interest rates on adjustable rate securities may lag behind changes in market rates, the value of such securities may decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. Prepayment risk — The risk that the principal on a bond that is held by a portfolio will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A portfolio may then have to reinvest that money at a lower interest rate. Foreign risk — The risk that foreign securities may be adversely affected by political instability, changes in currency exchange rates, inefficient markets and higher transaction costs, foreign economic conditions, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards. Emerging markets risk — The risk associated with international investing will be greater in emerging markets than in more developed foreign markets because, among other things, emerging markets may have less stable political and economic environments. In addition, there often is substantially less publicly available information about issuers and such information tends to be of a lesser quality. Economic markets and structures tend to be less mature and diverse and the securities markets may also be smaller, less liquid, and subject to greater price volatility. Forward foreign currency risk — The use of forward foreign currency contracts may substantially change a portfolio’s exposure to currency exchange rates and could result in losses to a fund if currencies do not perform as the portfolio manager expects. The use of these investments as a hedging technique to reduce a portfolio’s exposure to currency risks may also reduce its ability to benefit from favorable changes in currency exchange rates. Liquidity risk — The possibility that securities cannot be readily sold within seven days at approximately the price at which a portfolio has valued them. Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in the opposite direction from what the portfolio manager anticipated. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to financial difficulties (such as a bankruptcy or reorganization). Valuation risk — The risk that a less liquid secondary market may make it more difficult for a fund to obtain precise valuations of certain securities in its portfolio. Government and regulatory risk — The risk that governments or regulatory authorities may, from time to time, take or consider actions that could adversely affect various sectors of the securities markets and significantly affect fund performance.

| How has Delaware Floating Rate Fund performed?
|
The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual total returns for the 1-year, 5-year, and lifetime periods compare with those of a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how it will perform in the future. The returns reflect any expense caps in effect during these periods. The returns would be lower without the expense caps. You may obtain the Fund’s most recently available month-end performance by calling 800 523-1918 or by visiting our website at delawareinvestments.com/performance. Effective Jan. 31, 2017, the Fund was repositioned as a bank loan fund and changed its broad-based securities market index to the S&P/LSTA Leveraged Loan Index. The returns prior to Jan. 31, 2017 do not reflect these changes and accordingly, the performance shown in the bar chart and average annual total return table prior to that date may not be indicative of future returns.

| Year-by-year total return (Class A)
|
|
| During the periods illustrated in this bar chart, Class A’s highest quarterly return was 2.23% for the quarter ended March 31, 2012, and its lowest quarterly return was -2.42% for the quarter ended Sept. 30, 2011 . The maximum Class A sales charge of 2.75%, which is normally deducted when you purchase shares, is not reflected in the highest/lowest quarterly returns or in the bar chart. If this fee were included, the returns would be less than those shown. The average annual total returns in the table below do include the sales charge.

| After-tax performance is presented only for Class A shares of the Fund. The after-tax returns for other Fund classes may vary. Actual after-tax returns depend on the investor’s individual tax situation and may differ from the returns shown. After-tax returns are not relevant for shares held in tax-deferred investment vehicles such as employer-sponsored 401(k) plans and individual retirement accounts (IRAs). The after-tax returns shown are calculated using the highest individual federal marginal income tax rates in effect during the periods presented and do not reflect the impact of state and local taxes.
