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. 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:

Class A	Sold or Held	741	1,089	1,460	2,499
Class C	Sold	351	773	1,321	2,816
Class I	Sold or Held	151	468	808	1,768

Expense Example, No Redemption VIRTUS INTERNATIONAL REAL ESTATE SECURITIES FUND (USD $)	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold or Held	741	1,089	1,460	2,499
Class C	Held	251	773	1,321	2,816
Class I	Sold or Held	151	468	808	1,768

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 22%of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund provides international exposure to the real estate securities market, focusing exclusively on companies with a rental business profile. Rental companies derive 70% or more of total revenue from rental income and are most similar in business profile to U.S. real estate investment trusts (“REITs”).

Under normal circumstances, the fund invests at least 80% of its assets in equity securities issued by non-U.S companies of any capitalization that are principally engaged in the real estate industry, including common stock, preferred stock and other equity securities issued by real estate companies, such as REITs and similar REIT-like entities. The fund may, at times, invest up to 20% of its assets in U.S. REIT securities. Additionally, the fund normally invests in real estate related securities of issuers in developed countries, however it may invest up to 20% of its assets in issuers incorporated in emerging market countries. The fund concentrates its assets in the real estate industry.

Principal Risks

The fund may not achieve its objective, 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 subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The redemption by one or more large shareholders or groups of shareholders of their holdings in the fund could have an adverse impact on the remaining shareholders in the fund including by accelerating the realization of capital gains and increasing the fund's transaction costs. The principal risks of investing in the fund are:

>

• Emerging Market Investing Risk. The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

>

• Equity Real Estate Investment Trust (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 a 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 a particular style or in small or medium-sized companies may enhance that risk.

>

• Foreign Investing Risk. The risk that the prices of foreign securities in the fund’s portfolio will be more volatile than those of domestic securities, or will be negatively affected by currency fluctuations or economic, political or other developments.

>

• Geographic Concentration Risk. The risk that events negatively affecting the geographic location where the fund focuses its investments will cause the value of the fund’s shares to decrease, perhaps significantly.

>

• 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.

The S&P 500® Index is a free-float market capitalization-weighted index of 500 of the largest U.S. companies. The S&P 500® Index is calculated on a total return basis with dividends reinvested. The FTSE EPRA/NAREIT Developed Rental ex-U.S. Index is a free-float market capitalization index measuring international real estate securities, which meet minimum size, liquidity and investment focus criteria.

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.

[1] 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.

[2] The deferred sales charge is imposed on Class C Shares redeemed during the first year only.
