Fees and Expenses

The tables below illustrate all 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 $50,000 in Virtus Mutual Funds. More information about these and other discounts is available from your financial advisor and under “Sales Charges” on page 198 of the fund’s prospectus and “Alternative Purchase Arrangements” on page 91 of the fund’s statement of additional information.

Maximum Sales Charge (load) Imposed on Purchases (as a percentage of offering price)		5.75%			None			None			None
Maximum Deferred Sales Charge (load) (as a percentage of the lesser of purchase price or redemption proceeds)		1.00%	(a)		5.00%	(b)		1.00%	(b)		None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)	Class A		Class B		Class C		Class I

(a) Generally, Class A Shares are not subject to any charges by the Fund when redeemed; however, a contingent deferred sales charge may be imposed on certain redemptions (i) within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund; and (ii) on purchases on which a finder’s fee has been paid. The 18-month period begins on the last day of the month preceding the month in which the purchase was made.

(b) The maximum deferred sales charge is imposed on Class B Shares redeemed during the first year; thereafter, it decreases 1% annually to 2% during the fourth and fifth years and to 0% after the fifth year. The deferred sales charge is imposed on Class C Shares redeemed during the first year only.

(c) Restated to reflect current expenses.

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. It shows your costs if you sold your shares at the end of the period or continued to hold them. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. In the case of Class B Shares, it assumes that your shares are converted to Class A Shares after eight years. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	Share Status	1 Year		3 Years		5 Years		10 Years
Class A	Sold or Held		$710		$996		$1,302		$2,169
Class B	Sold		$619		$876		$1,159		$2,303
	Held		$219		$676		$1,159		$2,303

	Share Status	1 Year		3 Years		5 Years		10 Years
Class C	Sold		$319		$676		$1,159		$2,493
	Held		$219		$676		$1,159		$2,493
Class I	Sold or Held		$118		$368		$638		$1,409

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 24% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund offers exposure to the equity real estate investment trust (“REIT”) market utilizing a Growth at a Reasonable Price style with macroeconomic and fundamental security analysis to identify the most attractive investment candidates. The subadviser believes the value of a REIT extends beyond the value of the underlying real estate and that through fundamental research, it can uncover and exploit inefficiencies in the market.

Under normal circumstances, the fund invests at least 80% of its assets in publicly-traded REITs and companies that are principally engaged in the real estate industry. The fund concentrates its assets in the real estate industry and is non-diversified under federal securities laws.

Principal Risks

The fund may not achieve its objectives, and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the adviser expects. As a result, the value of your shares may decrease. The principal risks of investing in the fund are:

> Equity REIT Securities Risk. The risk that, in addition to the risks associated with investing in the real estate industry, the value of the fund’s shares will be negatively affected by factors specific to investing through a pooled vehicle, such as through poor management of the REIT or REIT-like entity, concentration risk, or other risks typically associated with investing in small or medium market capitalization companies.

> Equity Securities Risk. The risk that events negatively affecting issuers, industries or financial markets in which the fund invests will impact the value of the stocks held by the fund and thus, the value of the fund’s shares over short or extended periods. Investments in smaller companies may be more volatile than investments in larger companies.

> Industry/Sector Concentration Risk. The risk that events negatively affecting real estate securities will cause the value of the fund’s shares to decrease, perhaps significantly. Since the fund concentrates its assets in real estate related securities, the fund is more vulnerable to conditions that negatively affect real estate related securities as compared to a fund that does not concentrate holdings in such securities.

> Market Volatility Risk. The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.

> Non-Diversification Risk. The risk that the fund will be more susceptible to factors negatively impacting the securities in its portfolio to the extent that each such security represents a significant portion of the fund’s assets.

Performance Information

The bar chart and table below provide some indication of the potential risks of investing in the fund. The fund’s past performance, before and after taxes, is not necessarily an indication of how the fund will perform in the future.

The bar chart shows changes in the fund’s performance from year to year over a 10-year period. The table shows how the fund’s average annual returns compare to those of a broad-based securities market index and a more narrowly-based benchmark that reflects the market sectors in which the fund invests.

The S&P 500^® Index is a free-float market capitalization-weighted index of 500 of the largest U.S. companies. The FTSE NAREIT Equity REITs Index is a free-float market capitalization-weighted index measuring equity tax-qualified REITs, which meet minimum size and liquidity criteria, that are listed on the New York Stock Exchange, the American Stock Exchange and the NASDAQ National Market System. The indexes are calculated on a total return basis with dividends reinvested. The indexes are unmanaged and not available for direct investment.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. After-tax returns are shown only for Class A Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services.

Ask your financial advisor or visit your financial intermediary’s Web site for more information.
