Virtus Disciplined Equity Style Fund

Virtus Disciplined Equity Style Fund

Investment Objective

The fund has an investment objective of capital appreciation.

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, as well as eligibility requirements for each share class, is available from your financial advisor and under “Sales Charges” on page 22 of the fund’s prospectus and “Alternative Purchase Arrangements” on page of the fund’s statement of additional information.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees Virtus Disciplined Equity Style Fund	Class A		Class C		Class I
Maximum Sales Charge (load) Imposed on Purchases (as a percentage of offering price)	5.75%		none		none
Maximum Deferred Sales Charge (load) (as a percentage of the lesser of purchase price or redemption proceeds)	1.00%	[1]	1.00%	[2]	none

investment)

Total Annual Fund Operating Expenses After Expense Reimbursement		1.83%	2.58%	1.58%

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 and that the expense reimbursement arrangement remains in place only for the period indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example Virtus Disciplined Equity Style Fund (USD $)	1 Year	3 Year
Class A	750	1,117
Class C	361	802
Class I	161	499

Expense Example, No Redemption Virtus Disciplined Equity Style Fund (USD $)	1 Year	3 Year
Class A	750	1,117
Class C	261	802
Class I	161	499

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.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks to outperform the Russell 3000^® Index over a full market cycle in the U.S. equity market by tactically allocating net assets among six subsets of the U.S. equity universe that make up the Growth and Value equity styles as set forth below.

Growth:

• Large-Cap Growth

• Mid-Cap Growth

• Small-Cap Growth

Value:

• Large-Cap Value

• Mid-Cap Value

• Small-Cap Value

Allocations are based on a quantitative model that estimates performance trends for each pairing of these six subsets of the U.S. equity market relative to each other and uses these estimates to determine, on a weekly basis, whether the Growth or Value style is better positioned. The fund will invest assets in the equity style with the favorable aggregate score relative to the other style. The ability of the fund to outperform the Russell 3000^® Index will depend on, among other things, the length of time and degree to which Growth stocks outperform Value stocks or Value stocks outperform Growth stocks in the U.S. equity market.

Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund. Under normal circumstances, the fund intends to invest at least 80% of its assets in ETFs and/or securities representative of the U.S. equity market.

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. The principal risks of investing in the fund are:

• 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.

• Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.

• Fund of Funds Risk. The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.

• Growth Stocks Risk. The risk that the fund will underperform when growth investing is out of favor or that the fund’s investments will not appreciate as anticipated.

• 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.

• Small and Medium Market Capitalization Companies. Investments in small and medium market capitalization companies may be more volatile than investments in larger companies.

• Value Stocks Risk. The risk that the fund will underperform when value investing is out of favor or that the fund’s investments will not appreciate in value as anticipated.

Performance Information

The fund has not had a full calendar year of operations; therefore, performance information is not shown.

[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 within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund and 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.

[1] Estimated for current fiscal year.

[2] The fund's investment adviser has contractually agreed to limit the fund's total operating expenses (excluding interest, taxes, extraordinary expenses and acquired fund fees and expenses) so that such expenses do not exceed 1.60% for Class A Shares, 2.35% for Class C Shares and 1.35% for Class I Shares through December 31, 2013. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed under these arrangements for a period of three years following the fiscal year in which such reimbursement occurred.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks to maximize total return over a full market cycle in the bond market by tactically allocating net assets among six subsectors within the broad Treasury, TIPS and Corporate classifications of the bond market as set forth below:

Treasuries:

• Short term U.S. Treasury Securities (1-3 year maturities)

• Medium term U.S. Treasury Securities (7-10 year maturities)

• Long term U.S. Treasury securities (20+ year maturities)

Treasury Inflation Protected Securities (TIPS):

• TIPS

Corporate Bonds:

• Investment Grade Corporate Bonds

• High Yield Corporate Securities (Junk Bonds)

Allocations are based on a quantitative model that estimates performance trends for each pairing of these six subsectors of the bond market relative to each other and uses these estimates to generate, on a weekly basis, a positive or negative signal for each of the broad Treasury, TIPS and Corporate classifications. The classifications with positive signals will receive allocations, whereas the classifications with negative signals will not.

Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund. Under normal circumstances, the fund intends to invest at least 80% of its assets in ETFs and/or securities representative of the bond market.

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. The principal risks of investing in the fund are:

• Credit Risk. The risk that the issuer of a security will fail to pay interest or principal in a timely manner, or that negative perceptions of the issuer’s ability to make such payments will cause the price of the security to decline.

• Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.

• Fund of Funds Risk. The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.

• High Yield-High Risk Fixed Income Securities (Junk Bonds) Risk. The risk that the issuers of high yield-high risk securities in the fund’s portfolio will default, that the prices of such securities will be volatile, and that the securities will not be liquid.

• Interest Rate Risk. The risk that when interest rates rise, the values of the fund’s debt securities, especially those with longer maturities, will fall.

• 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.

• U.S. Government Securities Risk. The risk that U.S. Government securities in the fund’s portfolio will be subject to price fluctuations, or that an agency or instrumentality will default on an obligation not backed by the full faith and credit of the United States.

[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 within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund and 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] Estimated for current fiscal year.

[3] The fund's investment adviser has contractually agreed to limit the fund's total operating expenses (excluding interest, taxes, extraordinary expenses and acquired fund fees and expenses) so that such expenses do not exceed 1.40% for Class A Shares, 2.15% for Class C Shares and 1.15% for Class I Shares through December 31, 2013.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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.

Investments in smaller companies may be more volatile than investments in larger companies. Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly. Foreign Investing Risk. The risk that the prices of foreign securities may be more volatile than those of their domestic counterparts. Fund of Funds Risk. The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility. 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.

[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 within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund and 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] Estimated for current fiscal year.

Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed under these arrangements for a period of three years following the fiscal year in which such reimbursement occurred.

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.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks to outperform the MSCI EAFE^® Index over a full market cycle by tactically allocating net assets among countries included in the MSCI EAFE^® Index. In pursuing this strategy, the fund maintains an emphasis on preservation of capital.

Allocations are based on a quantitative model that provides a positive or negative signal, on a weekly basis, for each country evaluated. Countries with positive signals will receive allocations approximating their relative weights in the MSCI EAFE^® Index. The remaining portfolio assets will be allocated to the subadviser’s “minimum volatility portfolio,” which is designed to limit downside risk. The minimum volatility portfolio is allocated equally among the four countries that, in the subadviser’s opinion, have exhibited the lowest volatility pattern historically. To mitigate concentration, geographic, and political risk, the four countries in the minimum volatility portfolio cannot be from the same geographic or political region.

Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund. The fund may invest in issuers of any capitalization.

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. The principal risks of investing in the fund are:

• 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.

• Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.

• Foreign Investing Risk. The risk that the prices of foreign securities may be more volatile than those of their domestic counterparts.

• Fund of Funds Risk. The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.

• 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.

• Small and Medium Market Capitalization Companies. Investments in small and medium market capitalization companies may be more volatile than investments in larger companies.
