Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

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 39% of the average value of its portfolio.

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

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 or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The fund invests in asset-backed securities (“ABS”) issued or guaranteed by the U.S. Government, its agencies or instrumentalities, or issued by non-government entities, such as commercial banks or other private lenders, with an emphasis on investment-grade securities.

Under normal circumstances, the fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in investment grade tranches of ABS, and in other instruments that have economic characteristics similar to such investments.

Asset-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made periodically, thus in effect “passing through” such payments made by the individual borrowers on the assets that underlie the securities, net of any fees paid to the issuer or guarantor of the securities. The fund will invest exclusively in debt tranches of ABS. The types of ABS in which the fund may invest include those backed by auto loans, timeshare receivables, consumer loans, equipment leases, rentals, whole business securitizations, credit card receivables, and student loans, as well as any collateral type that is securitized but not listed above. There is no limitation on the maturity of the fund’s debt investments. The ABS in which the fund invests are generally purchased pursuant to Rule 144A under the Securities Act of 1933 and are therefore subject to certain resale restrictions.

Timeshare receivables are generated by vacation ownership interest in a divided form of property ownership, in which collateral can be secured with a fee simple interest in real estate or unsecured with the right to use the unit but no ownership interest in the real estate. Equipment lease securitizations represent interests in small, medium and large equipment leases, in which collateral can consist of various types of equipment, such as copiers, trucks, or construction equipment. Whole business securitizations represent franchise ownerships collateralized primarily by royalty fees paid by franchisees to franchisors, such as a percentage of the amount of sales generated. In addition, if the franchisor owns a store outright, a synthetic royalty or the operating profits of the owned store may be pledged as additional collateral to the securitization. Credit card receivables represent the securitization of a pool of credit card debt owed by consumers. Student loan securitizations are backed by pools of student loans. The cash flows generated from the underlying agreements for each of these types of ABS provide the bond holders with regular income.

For purposes of its investment objective, the fund defines a “relatively high level of income” as a level of income comparable to the yield to maturity of the agency component of the Bloomberg US Mortgage Backed Securities (MBS) Index. As of June 30, 2026, the yield to maturity of the agency component of the Bloomberg US Mortgage Backed Securities Index was 4.97%.

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.

Virtus Newfleet ABS MACS | Asset-Backed Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Asset-Backed Securities Risk: Changes in interest rates may cause both extension and prepayment risks for asset-backed securities. These securities are also subject to risks associated with the non-repayment of underlying collateral, including losses to the fund.
Virtus Newfleet ABS MACS | Income Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Credit Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Interest Rate Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Prepayment/Call Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Sector Focused Investing Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Sector Focused Investing Risk: Events negatively affecting the asset-backed securities sector and its sub-sectors, in which the fund focuses its investments may cause the value of the fund’s shares to decrease, perhaps significantly.
Virtus Newfleet ABS MACS | Illiquid and Restricted Securities Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Market Volatility Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> 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.
Virtus Newfleet ABS MACS | Large Shareholder Risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

> Large Shareholder Risk: Certain account holders, including the subadviser or funds or accounts over which the subadviser has investment discretion, may from time to time own or control a significant percentage of the fund’s shares. The fund is subject to the risk that a redemption by large shareholders of all or a portion of their fund shares or a purchase of fund shares in large amounts and/or on a frequent basis, including as a result of asset allocation decisions made by the subadviser, will adversely affect the fund’s performance if it is forced to sell portfolio securities or invest cash when the subadviser would not otherwise choose to do so. This risk will be particularly pronounced if one shareholder owns a substantial portion of the fund. Redemptions of a large number of shares may affect the liquidity of the fund’s portfolio, increase the fund’s transaction costs and/or lead to the liquidation of the fund. Such transactions also potentially limit the use of any capital loss carryforwards and certain other losses to offset future realized capital gains (if any). 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.

Neither the fund’s investment adviser nor the fund’s subadviser charges a management fee to the fund. Shareholders should be aware, however, that the fund is an integral part of separately managed account programs, and the fund’s investment adviser, the fund’s subadviser or their affiliates will be compensated directly or indirectly by separately managed account program sponsors or program participants for managed account advisory services.

The fund’s subadviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes (federal, state or otherwise), tax reclaim expenses, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, depositary receipt program fees, expenses incurred in connection with any merger or reorganization, expenses incurred in connection with any meeting of the fund's shareholders, unusual or infrequently occurring expenses, litigation expenses (including expenses for responding to document requests for litigation to which the fund is not a party), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 0.00% indefinitely. Only the fund’s Board may modify or terminate the expense limitation agreement.
