Example

The example below is intended to help you compare the cost of investing in the Fund to the cost of investing in other mutual funds. The example shows the cumulative amount of Fund expenses on a hypothetical investment of $10,000 with an annual 5% return over the time shown. This example assumes that the Fund's total operating expenses remain unchanged in each of the periods shown. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (Delaware Limited-Term Diversified Income Fund) (USD $)	1 year	3 years	5 years	10 years
Institutional Class	68	214	373	835

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 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 333% of the average value of its portfolio.

What are the Fund's principal investment strategies?

Under normal circumstances, the Fund will invest at least 80% of its net assets in investment grade fixed income securities, including, but not limited to, fixed income securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, and by U.S. corporations. Investment grade fixed income securities are securities rated BBB- or higher by Standard & Poor's (S&P), Baa3 or higher by Moody's Investors Service (Moody's), or similarly rated by another nationally recognized statistical rating organization (NRSRO), or those that are deemed to be of comparable quality. The Fund will maintain an average effective duration from one to three years. The Fund's investment manager, Delaware Management Company (Manager or we), will determine how much of the Fund's assets to allocate among the different types of fixed income securities in which the Fund may invest based on our evaluation of economic and market conditions and our assessment of the returns and potential for appreciation that can be achieved from various sectors of the fixed income market.

The corporate debt obligations in which the Fund may invest include bonds, notes, debentures, and commercial paper of U.S. companies and, subject to the limitations described below, non-U.S. companies. The Fund may also invest in a variety of securities that are issued or guaranteed as to the payment of principal and interest by the U.S. government, and by various agencies or instrumentalities, which have been established or are sponsored by the U.S. government, and, subject to the limitations described below, securities issued by foreign governments.

Additionally, the Fund may invest in mortgage-backed securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, government-sponsored corporations, and mortgage-backed securities issued by certain private, nongovernment entities. The Fund may also invest in securities that are backed by assets such as receivables on home equity and credit card loans, automobile, mobile home, recreational vehicle and other loans, wholesale dealer floor plans, and leases.

The Fund may invest up to 20% of its net assets in below-investment-grade securities (also known as high yield or "junk" bonds). In general, the below-investment-grade securities that the Fund may purchase in this sector will generally be rated BB or lower by S&P and Ba or lower by Moody's, or similarly rated by another NRSRO.

The Fund may also invest up to 30% of its net assets in foreign securities, including up to 10% of its net assets in securities of issuers located in emerging markets. The Fund's total non-U.S. dollar currency exposure will be limited, in the aggregate, to no more than 10% of net assets.

The Fund may use a wide range of derivative instruments, typically including options, futures contracts, options on futures contracts, and swaps. The Fund will use derivatives for both hedging and nonhedging purposes. For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against bond defaults, to manage credit exposure or to enhance total return; and index swaps to enhance return or to affect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective and will limit its investments in derivative instruments to 20% of net assets.

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. Principal risks include:

Investments not guaranteed by the Manager or its affiliates — Investments in the Fund are not and will not be deposits with or liabilities of Macquarie Bank Limited ABN 46 008 583 542 and its holding companies, including their subsidiaries or related companies (Macquarie Group), and are subject to investment risk, including possible delays in repayment and loss of income and capital invested. No Macquarie Group company guarantees or will guarantee the performance of the Fund, the repayment of capital from the Fund, or any particular rate of return.

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.

Interest rate risk — The risk that securities will decrease in value if interest rates rise. This risk is generally associated with bonds.

Credit risk — The risk that an issuer of a debt security, including a governmental issuer, may be unable to make interest payments and repay principal in a timely manner.

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; and greater price volatility and risk of loss of income and principal than are higher rated 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.

Liquidity risk — The possibility that securities cannot be readily sold within seven days at approximately the price at which a fund has valued them.

Derivatives risk — Derivative contracts, such as options, futures, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, or a securities index to which a derivative contract is associated, moves in the opposite direction from what the portfolio manager anticipated. Derivative 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).

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected by political instability; changes in currency exchange rates; inefficient markets and higher transaction costs; foreign economic conditions; or inadequate or different regulatory and accounting standards.

Bank 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.

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 have, from time to time, taken or considered actions that could adversely affect various sectors of the securities markets.

Effective November 30, 2007, the Fund's investment objective, strategies, and policies were changed to permit the Fund to invest in a diversified portfolio of limited-term fixed income securities.

Prior to November 30, 2007, the Fund invested primarily in U.S. government securities.
