Risk Table - Virtus Ceredex Large-Cap Value Equity Fund	Risk [Text Block]
Principal Risks	Principal Risks The fund may not achieve its objective(s), 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 principal risks of investing in the fund are identified below.
Risk Lose Money [Member]	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.
Equity Securities Risk	> Equity Securities Risk: The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.
Value Stocks Risk	> Value Stocks Risk: The fund may underperform when value investing is out of favor or the fund’s investments may not appreciate in value as anticipated.
Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Sector Focused Investing Risk	> Sector Focused Investing Risk: Events negatively affecting a particular market sector in which the fund focuses its investments may cause the value of the fund’s shares to decrease, perhaps significantly.
Large Market Capitalization Companies Risk	> Large Market Capitalization Companies Risk: The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
Depositary Receipts Risk	> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s NAV and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.

Risk Lose Money [Member]	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.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Interest Rate Risk	> Interest Rate Risk: The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities.
Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Mortgage-Backed and Asset-Backed Securities Risk	> Mortgage-Backed and Asset-Backed Securities Risk: Changes in interest rates may cause both extension and prepayment risks for mortgage-backed and asset-backed securities. These securities are also subject to risks associated with the non-repayment of underlying collateral, including losses to the fund.
Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Emerging Market Risk	> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Sanctions Risk	> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.
High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk	> High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk: There is a greater risk of issuer default, less liquidity, and increased price volatility related to high-yield/high-risk securities than investment grade securities, and high-yield/high-risk securities are generally considered to be speculative.
Illiquid and Restricted Securities Risk	> Illiquid and Restricted Securities Risk: Certain securities in which the fund invests may be difficult to sell at the time and price beneficial to the fund, for example due to low trading volumes or legal restrictions.
Income Risk	> Income Risk: Income received from the fund may vary widely over the short- and long-term and/or be less than anticipated if the proceeds from maturing securities in the fund are reinvested in lower-yielding securities.
Inflation-Linked Investments Risk	> Inflation-Linked Investments Risk: Inflation-linked securities may react differently from other fixed income securities to changes in interest rates and that interest and/or principal payments on an inflation-protected security may be irregular. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in their value. In addition, positive adjustments to principal in inflation-protected securities generally can be expected to result in taxable income to the Underlying Fund at the time of such adjustments, even though the principal amount is not paid until maturity.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Prepayment/Call Risk	> Prepayment/Call Risk: Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the fund to reinvest in obligations with lower interest rates and the fund may not benefit fully from the increase in value that other fixed income investments experience when interest rates decline.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle.

Unrated Fixed Income Securities Risk	> Unrated Fixed Income Securities Risk: If the subadviser is unable to accurately assess the quality of an unrated fixed income security, the fund may invest in a security with greater risk than intended, or the securities may be more difficult to sell than anticipated.
Government Securities Risk	> U.S. Government Securities Risk: U.S. Government securities may be subject to price fluctuations. An agency may default on an obligation not backed by the full faith and credit of the United States. Any guarantee on U.S. government securities does not apply to the value of the fund’s shares.

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 municipalities 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 principal risks of investing in the fund are identified below.
Risk Lose Money [Member]	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.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Interest Rate Risk	> Interest Rate Risk: The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities.
Municipal Securities Risk	> Municipal Securities Risk: Events negatively impacting a municipality, municipal security, or the municipal bond market in general, may cause the fund to decrease in value, perhaps significantly.
Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Income Risk	> Income Risk: Income received from the fund may vary widely over the short- and long-term and/or be less than anticipated if the proceeds from maturing securities in the fund are reinvested in lower-yielding securities.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Prepayment/Call Risk	> Prepayment/Call Risk: Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the fund to reinvest in obligations with lower interest rates and the fund may not benefit fully from the increase in value that other fixed income investments experience when interest rates decline.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s NAV and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.
Tax-Exempt Securities Risk	> Tax-Exempt Securities Risk: Tax-exempt securities may not provide a higher after-tax return than taxable securities, and/or the tax-exempt status may be lost or limited.
Tax Liability Risk	> Tax Liability Risk: Noncompliant conduct by a municipal bond issuer, or certain adverse interpretations or actions by a government or tax authority, could cause interest from a security to become taxable, possibly retroactively, subjecting shareholders to increased tax liability.
Unrated Fixed Income Securities Risk	> Unrated Fixed Income Securities Risk: If the subadviser is unable to accurately assess the quality of an unrated fixed income security, the fund may invest in a security with greater risk than intended, or the securities may be more difficult to sell than anticipated.

Interest Rate Risk	> Interest Rate Risk: The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities.
Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Emerging Market Risk	> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Mortgage-Backed and Asset-Backed Securities Risk	> Mortgage-Backed and Asset-Backed Securities Risk: Changes in interest rates may cause both extension and prepayment risks for mortgage-backed and asset-backed securities. These securities are also subject to risks associated with the non-repayment of underlying collateral, including losses to the fund.
High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk	> High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk: There is a greater risk of issuer default, less liquidity, and increased price volatility related to high-yield/high-risk securities than investment grade securities, and high-yield/high-risk securities are generally considered to be speculative.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.

Bank Loan Risk	> Bank Loan Risk: In addition to the risks typically associated with high-yield/high-risk fixed income securities, bank loans may be unsecured or not fully collateralized, may be subject to restrictions on resale, may be less liquid and may trade infrequently on the secondary market. Bank loans settle on a delayed basis; thus, sale proceeds may not be available to meet redemptions for a substantial period of time after the sale of the loan.
Illiquid and Restricted Securities Risk	> Illiquid and Restricted Securities Risk: Certain securities in which the fund invests may be difficult to sell at the time and price beneficial to the fund, for example due to low trading volumes or legal restrictions.
Income Risk	> Income Risk: Income received from the fund may vary widely over the short- and long-term and/or be less than anticipated if the proceeds from maturing securities in the fund are reinvested in lower-yielding securities.
Inflation-Linked Investments Risk	> Inflation-Linked Investments Risk: Inflation-linked securities may react differently from other fixed income securities to changes in interest rates and that interest and/or principal payments on an inflation-protected security may be irregular. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in their value. In addition, positive adjustments to principal in inflation-protected securities generally can be expected to result in taxable income to the Underlying Fund at the time of such adjustments, even though the principal amount is not paid until maturity.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Prepayment/Call Risk	> Prepayment/Call Risk: Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the fund to reinvest in obligations with lower interest rates and the fund may not benefit fully from the increase in value that other fixed income investments experience when interest rates decline.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s NAV and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.
Sanctions Risk	> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.
Unrated Fixed Income Securities Risk	> Unrated Fixed Income Securities Risk: If the subadviser is unable to accurately assess the quality of an unrated fixed income security, the fund may invest in a security with greater risk than intended, or the securities may be more difficult to sell than anticipated.
Government Securities Risk	> U.S. Government Securities Risk: U.S. Government securities may be subject to price fluctuations. An agency may default on an obligation not backed by the full faith and credit of the United States. Any guarantee on U.S. government securities does not apply to the value of the fund’s shares.
