Before considering an investment in the Fund, you should understand that you could lose money.
The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, region, market, industry, group of industries, project types, group of project types, sector or asset class.
Municipal bond risks include the ability of the issuer to repay the obligation, the relative lack of information about certain issuers, and the possibility of future tax and legislative changes, which could affect the market for and value of municipal securities.
Fixed income securities most frequently trade in institutional round lot size transactions. Until the Fund grows significantly in size,the Fund expects to purchase a significant number of bonds in amounts less than the institutional round lot size, which are frequently referred to as “odd” lots. Odd lot size positions may have more price volatility than institutional round lot size positions.
Insured Municipal Bonds are covered by insurance policies that guarantee the timely payment of principal and interest. The insurance does not guarantee the market value of an insured security, or the Fund’s share price or distributions, and shares of the Fund are not insured. The Fund may purchase insurance for an uninsured bond directly from a qualified Municipal Bond insurer. The supply of insured municipal securities which meet the Fund’s investment guidelines is limited.
A portion of the Fund's income may be subject to state and local taxes or the alternative minimum tax.
Funds that invest in bonds are subject to interest-rate risk and can lose principal value when interest rates rise. Bonds are also subject to credit risk, in which the bond issuer may fail to pay interest and principal in a timely manner.
Bloomberg Municipal Insured Bond Index is a total return performance benchmark for municipal bonds that are backed by insurers with Aaa/AAA ratings and have maturities of at least one year.
An investment cannot be made directly into an index.
Annual Turnover Rate is as of the most recent annual shareholder report.
Duration to Worst is the duration of a bond, computed using the bond's nearest call date or maturity, whichever comes first. This measure ignores future cash flow fluctuations due to embedded optionality.
Final Maturity is the weighted average of the stated time to maturity for the securities held in the portfolio.
Shares are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Total Returns are calculated using the daily 4:00 pm ET net asset value (NAV). Since May 31, 2016, the price used to calculate the market price returns ("MP") is the mean between the day's last bid and ask prices on the fund's primary exchange. Any market price returns prior to May 31, 2016 were calculated using the day's closing price on the fund's primary exchange. The market price returns do not represent returns an investor would receive if shares were traded at other times.
Fund shares are not individually redeemable and will be issued and redeemed at their NAV only through certain authorized broker-dealers in large, specified blocks of shares called "creation units", and otherwise, can be bought and sold only through exchange trading. Creation units are issued and redeemed principally in-kind.
The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance (this does not include the effects of sales charges, loads, and redemption fees). The top 10% of products in each product category receive 5stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
