oef_ExpenseNarrativeTextBlock

The tables below illustrate the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Funds. More information on these and other discounts is available: (i) from your financial professional or other financial intermediary; (ii) under “Sales Charges” on page 86 of the fund’s prospectus; and (iii) with respect to purchase of shares through specific intermediaries, in Appendix A to the fund’s prospectus, entitled “Intermediary Sales Charge Discounts and Waivers.”

The Virtus Seix Floating Rate High Income Fund, a series of Virtus Asset Trust, is the successor of the RidgeWorth Seix Floating Rate High Income Fund, a series of RidgeWorth Funds (“Predecessor Fund”), resulting from a reorganization of the Predecessor Fund with and into the fund.

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

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 63% of the average value of its portfolio.

Strategy Narrative [Text Block]

oef_StrategyNarrativeTextBlock

Under normal circumstances, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a combination of first- and second-lien senior floating rate loans and other floating rate debt instruments, including both secured loans and “covenant lite” loans which have few or no financial maintenance covenants that would require a borrower to maintain certain financial metrics. These loans are loans made by banks and other large financial institutions to various companies and are senior in the borrowing companies’ capital structure. Coupon rates are generally floating, not fixed, and are tied to a benchmark lending rate or set at a specified floor, whichever is higher.

The fund invests all or substantially all of its assets in first- and second-lien senior floating rate loans, or debt instruments that are rated below investment grade by Moody’s and Standard & Poor’s (sometimes referred to as “junk bonds”) or in comparable unrated instruments. The fund may also invest up to 20% of its net assets in any combination of junior debt instruments or instruments with a lien on collateral lower than a senior claim on collateral, high yield fixed-rate bonds, investment grade fixed income debt obligations, asset-backed securities (such as special purpose trusts investing in bank loans), and short-term investments, including money market securities and repurchase agreements. The fund may invest a portion of its assets in instruments that are restricted as to resale.

In selecting investments for purchase and sale, the subadviser will emphasize loans and instruments which are within the segment of the high yield market it has targeted, which are loans and instruments rated below investment grade or unrated loans and instruments that the subadviser believes are of comparable quality. The fund may invest up to 20% of its total assets in senior loans made to non-U.S. borrowers provided that no more than 5% of the portfolio’s loans are non-U.S. dollar denominated. There are no limits on the fund’s average-weighted maturity or on the remaining maturities of individual instruments in which the fund may invest. The fund may also engage in certain hedging transactions.

In order to meet short-term liquidity needs, the fund employs a variety of techniques, such as investing in highly-liquid fixed income instruments and holding a portion of its assets in cash. Although not a principal investment strategy, the fund may, under certain market conditions, borrow an amount up to 33 1/3% of its total assets (including the amount borrowed) for investment purposes, to meet redemption requests and for temporary, extraordinary or emergency purposes.

Some types of senior loans in which the fund may invest require that an open loan for a specific amount be continually offered to a borrower. These types of senior loans are commonly referred to as revolvers. Because revolvers contractually obligate the lender (and therefore those with an interest in the loan) to fund the revolving portion of the loan at the borrower’s discretion, the fund must have funds sufficient to cover its contractual obligation. Therefore, the fund will maintain, on a daily basis, high-quality, liquid assets in an amount at least equal in value to its contractual obligation to fulfill the revolving senior loan. The fund will not encumber any assets that are otherwise encumbered.

In addition, to implement its investment strategy, the fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures, credit linked notes, options and warrants) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks. The fund may count the value of certain derivatives with floating rate loan or high yield bond characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in a combination of first- and second-lien senior floating rate loans and other floating rate debt instruments.

Performance Table Uses Highest Federal Rate

oef_PerformanceTableUsesHighestFederalRate

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 I 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.

> 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.

Risk/Return:

Risk [Text Block]

oef_RiskTextBlock

> 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.

Risk/Return:

> 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.

Risk/Return:

> Covenant Lite Loans Risk: The lack of financial maintenance covenants in covenant lite loans increases the risk that the fund will experience difficulty or delays in enforcing its rights on its holdings of such loans, which may result in losses, especially during a downturn in the credit cycle.

> 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.

> 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.
