The Series 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. These costs, which are not reflected in Annual Series Operating Expenses or in the Example, affect the Series’ performance. During the most recent fiscal year, the Series’ portfolio turnover rate was 59% of the average value of its portfolio.

Strategy Narrative [Text Block]

oef_StrategyNarrativeTextBlock

The Series seeks to generate a competitive total return, inclusive of a high level of current income, by applying extensive credit research and a time-tested approach to capitalize on opportunities across undervalued sectors of the bond market. The Series seeks diversification across the full fixed income universe as described below in order to increase return potential and reduce risk.

Under normal circumstances, the Series invests at least 80% of its assets in fixed income securities. For purposes of this policy, indirect exposure to fixed income securities through investment in mutual funds and exchange-traded funds (ETFs) that invest in such securities will be considered to be investments by the Series in fixed income securities. Mutual funds and ETFs in which the Series invests may include affiliated funds that are also managed by the Series’ subadviser. The Series seeks to achieve its objective by investing in a diversified portfolio of primarily intermediate-term bonds having a dollar-weighted average duration of between three and ten years and that are in one of the following market sectors:

 Securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies, authorities or instrumentalities. Sectors include U.S. Treasuries and Agency Debentures;

 Collateralized mortgage obligations (“CMOs”), real estate mortgage investment conduits (“REMICs”) and other pass-through securities, including those issued or guaranteed as to principal and interest by the U.S. Government, its agencies, authorities or instrumentalities. Sectors include Asset-backed Securities (ABS), Commercial Mortgage-Backed Securities (CMBS), Non-agency Residential Mortgage-Backed Securities (RMBS), and Agency Residential Mortgage-Backed Securities (MBS);

 Debt instruments issued by foreign issuers, including foreign governments and their political subdivisions and issuers located in emerging markets. Sectors include Emerging Markets Sovereign High Yield, Emerging Markets Sovereign Investment Grade, Emerging Markets Local Currency, Emerging Markets Corporates and Euro High Yield;

 Investment grade securities (primarily of U.S. issuers, secondarily of non-U.S. issuers), which are securities with credit ratings within the four highest rating categories of a nationally recognized statistical rating organization, including short-term securities. Sectors include Investment Grade Corporates, Municipals, and Taxable Municipals; and

 High-yield debt instruments (so-called “junk bonds”), including bank loans (which are generally floating-rate loans). Sectors include High Yield Corporates and Bank Loans, 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.

The Series may invest in all or some of these sectors.

The Series may use derivative instruments to increase or hedge (decrease) investment exposure to various fixed income sectors and instruments, including, but not limited to, swaps, futures contracts and currency forwards.

The Series manages duration utilizing a duration neutral strategy.

Performance Narrative [Text Block]

oef_PerformanceNarrativeTextBlock

The following bar chart and table provide some indication of the risks of investing in the Series. The bar chart shows changes in the Series’ performance from year to year over a 10-year period. The Series’ past performance is not necessarily an indication of how the Series will perform in the future. The table shows how the Series’ average annual returns compare to those of a broad-based securities market index. The Series’ returns in the chart and table do not reflect the deduction of any separate account or variable contract charges. The returns would have been less than those shown if such charges were deducted. Updated performance information is available at virtus.com or by calling 800-367-5877.

If between the time you purchase shares and the time you sell shares the value of the Series’ investments decreases, you will lose money.

> 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:

> 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.

> 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: 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 Series.

> Affiliated Fund and ETF Risk: The Series’ subadviser may select and substitute affiliated and/or unaffiliated mutual funds and/or exchange-traded funds (ETFs), which may create a conflict of interest because the subadviser or its affiliate(s) may receive fees from affiliated funds and/or ETFs, some of which pay the subadviser or its affiliate(s) more than others.

> 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 Series may incur a loss greater than its principal investment.

> Mutual Fund and ETF Investing Risk: The Series will be indirectly affected by factors, risks and performance specific to any other mutual fund and/or exchange-traded fund (ETF) (“underlying fund”) in which it invests. Further, the net asset value per share of each underlying fund will include the effect of any fees and expenses of the underlying fund, so the Series’ investment in such underlying funds will cause the Series to indirectly bear its proportionate share of such fees and expenses, which are reflected in the Series’ Fees and Expenses table as “Acquired Fund Fees and Expenses” if they are estimated to amount to at least 0.01% of the Series’ total net assets.

> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the Series, resulting in an adverse impact on remaining shareholders in the Series by causing the Series to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of Series shares would particularly impact non-redeeming shareholders who do not hold their Series shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a Series to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Series’ NAV and liquidity. In addition, a large redemption could result in the Series’ current expenses being allocated over a smaller asset base, leading to an increase in the Series’ expense ratio.
