Fees and Expenses

The tables below illustrate the fees and expenses that you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Mutual Funds. More information about these and other discounts is available from your financial advisor and under “Sales Charges” on page 201 of the fund’s prospectus and “Alternative Purchase Arrangements” on page 105 of the fund’s statement of additional information.

Shareholder Fees (fees paid directly from your investment)	Class A	Class I
Maximum Sales Charge (load) Imposed on Purchases (as a percentage of offering price)	2.75%	None
Maximum Deferred Sales Charge (load) (as a percentage of the lesser of purchase price or redemption proceeds)	None	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)	Class A	Class I
Management Fees	0.45%	0.45%
Distribution and Shareholder Servicing (12b-1) fees	0.25%	None
Other Expenses	0.48%	0.48%
Total Annual Fund Operating Expenses	1.18%	0.93%
Less: Fee Waiver and/or Expense Reimbursement(a)	(0.33)%	(0.33)%
Total Annual Fund Operating Expenses After Expense Reimbursement(a)	0.85%	0.60%

(a)

The fund's investment adviser has contractually agreed to limit the fund's total operating expenses (excluding dividend and interest expenses, taxes, brokerage commissions, extraordinary expenses and acquired fund fees and expenses) so that such expenses do not exceed 0.85% for Class A Shares and 0.60% for Class I Shares through January 31, 2017. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed under these arrangements for a period of three years following the fiscal year in which such reimbursement occurred.

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, 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:

	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold or Held	$359	$608	$875	$1,639
Class I	Sold or Held	$61	$263	$482	$1,113

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 24% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks current income free from federal and state income taxes by investing in municipal bonds issued in the state of California. The management team focuses on high quality California tax-exempt municipal bonds, gauging the value of a security by issue type, credit quality, and bond structure; however, the fund may invest up to 20% of its net assets in below investment grade tax-exempt municipal bonds. Below investment grade tax-exempt municipal bonds are considered high-yield/high-risk fixed income securities.

Under normal circumstances, as a matter of fundamental policy, the fund invests at least 80% of its assets in bonds, the income from which is exempt from California state income tax and federal income tax, and may invest 100% of its assets in such securities. The portion of the fund’s assets not invested in tax-exempt securities may be invested in taxable fixed income securities. Income from these investments may be subject to federal, state and local taxes.

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. Debt securities rated below investment-grade are especially susceptible to this risk.

Geographic Concentration Risk. The risk that events negatively affecting the geographic location where the fund focuses its investments will cause the value of the fund’s shares to decrease, perhaps significantly.

High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk. The risk that 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.

Long-Term Maturities/Durations Risk. The risk of greater price fluctuations than would be associated with securities having shorter maturities or durations.

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

Municipal Bond Market Risk. The risk that events negatively impacting a particular municipal security, or the municipal bond market in general, will cause the value of the fund’s shares to decrease, perhaps significantly.

Tax-Exempt Securities The risk that tax-exempt securities may not provide a higher after-tax return than taxable securities, or that the tax-exempt status of such securities may be lost or limited.

Unrated Fixed Income Securities Risk. The risk that the subadviser will be unable to accurately assess the quality of an unrated fixed income security, so that the fund invests in a security with greater risk than intended, or that the liquidity of unrated fixed income securities in which the fund invests will be hindered, making it difficult for the fund to sell them.

The Barclays U.S. Aggregate Bond Index measures the U.S. investment grade fixed rate bond market. The Barclays California Municipal Bond Index measures long term investment grade, tax-exempt and fixed rate bonds issued in California. The indexes are calculated on a total return basis. The indexes are 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.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies may pay the intermediary for the sale of fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the fund over another investment. Ask your financial advisor or visit your financial intermediary’s Web site for more information.
