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. In the case of Class B Shares, it assumes that your shares are converted to Class A Shares after six years. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - VIRTUS MULTI-SECTOR SHORT TERM BOND FUND - USD ($)	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold	325	536	765	1,422
Class B	Sold	303	474	818	1,532
Class C	Sold	127	397	686	1,511
Class I	Sold	77	240	417	930
Class R6	Sold	69	218	379	847
Class T	Sold	275	525	875	1,750

Class T	Held	175	525	875	1,750

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. During the most recent fiscal year, the fund's portfolio turnover rate was 53%of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks current income with an emphasis on maintaining low volatility and overall short duration by investing primarily in higher quality, more liquid securities across 14 bond market sectors. The fund utilizes a value-oriented, research driven approach that seeks to strategically overweight undervalued sectors while applying strict risk controls.

Under normal circumstances, the fund invests at least 80% of its assets in bonds, which are fixed income debt obligations of various types of issuers. The fund seeks to achieve its objective by investing in a diversified portfolio of primarily short-term fixed income securities having an expected dollar-weighted average maturity of three years or less 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;

•    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;

•    Debt securities issued by foreign issuers, including foreign governments and their political subdivisions, and issuers located in emerging markets;

•    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; and

•    High-yield/high-risk debt instruments (so-called "junk bonds"), including bank loans (which are generally floating-rate).

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

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 redemption by one or more large shareholders or groups of shareholders of their holdings in the fund could have an adverse impact on the remaining shareholders in the fund including by accelerating the realization of capital gains and increasing the fund's transaction costs. 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.

>     Emerging Market Investing Risk.  The risk that prices of emerging markets securities will be more volatile, or will be more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

>     Foreign Investing Risk.  The risk that the prices of foreign securities in the fund's portfolio will be more volatile than those of domestic securities, or will be negatively affected by currency fluctuations, less regulated or liquid securities markets, or economic, political or other developments.

>     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 issuers and/or general economic conditions. Price changes may be temporary or may last for extended periods.

>     Mortgage-Backed and Asset-Backed Securities Risk.  The risk that changes in interest rates will cause both extension and prepayment risks for mortgage-backed and asset-backed securities in which the fund invests, or that an impairment of the value of collateral underlying such securities will cause the value of the securities to decrease.

>     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.

The BofA Merrill Lynch 1-3 Year A-BBB US Corporate Index measures performance of U.S. corporate bond issues rated A1 through BBB3, inclusive (based on an average of Moody's, S&P and Fitch), with a remaining term to final maturity less than 3 years. The index is calculated on a total return basis. The index is unmanaged and not available for direct investment. 

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 A 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.

[1] The maximum deferred sales charge is imposed on Class B Shares redeemed during the first year; thereafter, it decreases 0.50% annually to 1% during the third year and to 0% after the third year. The deferred sales charge is imposed on Class T Shares redeemed during the first year only.

[1] Estimated for current fiscal year, as annualized.

[2] The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets appearing in the Financial Highlights tables, which tables reflect only the operating expenses of the fund and do not include acquired fund fees and expenses.
