¹ SEC yield is a measure of the income generated by the portfolio's underlying asset over the trailing 30 days, relative to the asset base of the portfolio itself. The SEC 30-day yield -Subsidized (Sub.) reflects current fee waivers in effect. Absent such fee waivers, the yield would have been lower. The SEC 30-Day yield- Unsubsidized (Unsub.) does not reflect the fee waivers currently in effect.

² Where the net expense ratio is lower than the gross expense ratio, certain fees have been waived and/or expenses reimbursed. These waivers and/or reimbursements will continue for at least one year from the date of the applicable fund's current prospectus (unless otherwise noted in the applicable prospectus) or until such time as the fund's Board of Directors acts to discontinue all or a portion of such waivers and/or reimbursements. Absent such waivers and/or reimbursements, returns would have been lower. Expenses are based on the fund's current prospectus.

See the Fund's prospectus for information related to a primary benchmark index selected (if applicable) to comply with a regulation that requires the Fund's primary benchmark to represent the overall applicable market.

³ The ICE BofA 1-3 Year US Municipal Securities Index is designed to track the performance of USD-denominated taxable municipal debt that is issued publicly by states and territories within the United States, as well as their political subdivisions, in the U.S. market.

⁴ Characteristics Definitions:
Duration is a measure of the sensitivity of the price (the value of principal) of a fixed income investment to a change in interest rates. Duration is expressed as a number of years. Rising interest rates mean falling bond prices, while declining interest rates mean rising bond prices. Effective duration takes into account that expected cash flows will fluctuate as interest rates change. Average Effective Maturity is a measure of sensitivity to liquidity and/or credit risk. Average effective maturity takes into account all call options exercised by the issuer as well as permissible maturity shortening devices such as demand features. Average effective maturity is computed using the nearest call date or maturity, whichever comes first. A bond's Average price is calculated by adding its face value to the price paid for it and dividing the sum by two. The average price is sometimes used in determining a bond's yield to maturity where the average price replaces the purchase price in the yield to maturity calculation. The Yield to Maturity (YTM) is the rate of return anticipated on a bond or other obligation if held to maturity. Distribution Rate is the annual yield an investor would receive if the most recent fund distribution remained the same going forward. The distribution yield is calculated by dividing the normalized current distribution (annualized) by the fund NAV per share. Yield To Worst is the lowest potential yield that can be received on a bond without the issuer actually defaulting. The yield to worst is calculated by making worst-case scenario assumptions on the issue by calculating the returns that would be received if provisions, including prepayment, call or sinking fund, are used by the issuer. Option Adjusted Spread (OAS) is a measurement of the spread of a fixed-income security rate and the risk-free rate of return, which is adjusted to take into account an embedded option. Typically, an analyst would use the Treasury securities yield for the risk-free rate. The spread is added to the fixed-income security price to make the risk-free bond price the same as the bond. Average coupon is the weighted-average gross interest rates of the pool of mortgages that underlie a mortgage-backed security (MBS) at the time the securities were issued. In the weighted-average calculation, the principal balance of each underlying mortgage is used as the weighting factor.

R squared measures how well an investment’s returns correlate to an index. An R squared of 100 means the portfolio performance is 100% correlated to the index’s, whereas a low r-squared means that the portfolio performance is less correlated to the index’s. Sharpe ratio is a risk-adjusted measure calculated as the ratio of excess return to standard deviation. The Sharpe ratio determines reward per unit of risk. The higher the Sharpe ratio, the better the historical risk-adjusted performance. 

Credit ratings are categorized using S&P. Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer's creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P's measures. Ratings of BBB or higher by S&P are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency's analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer's current financial condition and does not necessarily reflect its assessment of the volatility of a security's market value or of the liquidity of an investment in the security. Holdings designated as "Not Rated" are not rated by S&P.

Risk Considerations: There is no assurance that a portfolio will achieve its investment objective. Portfolios are subject to market risk, which is the possibility that the market values of securities owned by the portfolio will decline. Market values can change daily due to economic and other events (e.g. natural disasters, health crises, terrorism, conflicts and social unrest) that affect markets, countries, companies or governments. It is difficult to predict the timing, duration, and potential adverse effects (e.g. portfolio liquidity) of events. Accordingly, you can lose money investing in this portfolio. Please be aware that this portfolio may be subject to certain additional risks. Fixed-income securities are subject to the ability of an issuer to make timely principal and interest payments (credit risk), changes in interest rates (interest-rate risk), the creditworthiness of the issuer and general market liquidity (market risk). In a rising interest-rate environment, bond prices may fall and may result in periods of volatility and increased portfolio redemptions. In a declining interest-rate environment, the portfolio may generate less income. Longer-term securities may be more sensitive to interest rate changes. By investing in municipal obligations, the Fund may be susceptible to political, economic, regulatory or other factors affecting their issuers. While interest earned on municipal securities is generally not subject to federal income tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to state and/or local income tax. High yield securities (“junk bonds”) are lower rated securities that may have a higher degree of credit and liquidity risk. Tender option bonds. The risks of tender option bonds include the risk that the owner of such instrument may not be considered the owner for federal income tax purposes and thus will not be entitled to treat such interest as exempt from federal income tax. Taxability risk. Changes in tax laws or adverse determinations by the Internal Revenue Service (“IRS”) may make the income from some municipal obligations taxable. When-Issued Securities, Delayed Delivery Securities, TBAs and Forward Commitments. These investments may result in a form of leverage and may increase volatility in the Fund’s share price.  They are subject to risks such as failure of the counterparty to perform its obligation to deliver the security, the characteristics of a security delivered to the Fund may be less favorable than expected and the security the Fund buys will lose value prior to its delivery. A high portfolio turnover rate could result in high brokerage costs and an increase in taxable capital gains distributions.  Illiquid securities may be more difficult to sell and value than publicly traded securities (liquidity risk). Revenue Bonds. Revenue bonds historically have been subject to a greater risk of default than general obligation bonds because investors can look only to the revenue generated by the project or other revenue source backing the project. Authorized Participant Concentration Risk. The Portfolio has a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. As a result, shares may trade at a discount to net asset value (“NAV”) and possibly face trading halts and/or delisting. Trading Risk. The market prices of Shares are expected to fluctuate, in some cases materially, in response to changes in the Portfolio's NAV, the intra-day value of holdings, and supply and demand for Shares. The Adviser cannot predict whether Shares will trade above, below or at their NAV. Buying or selling Shares in the secondary market may require paying brokerage commissions or other charges imposed by brokers as determined by that broker.

Morningstar
Rankings: The percentile rankings are based on the average annual total returns for the periods stated and do not include any sales charges, but do include reinvestment of dividends and capital gains and Rule 12b-1 fees. The highest (or most favorable) percentile rank is 1 and the lowest (or least favorable) percentile rank is 100. The top-performing fund in a category will always receive a rank of 1.

Ratings: 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. The top 10% of products in each product category receive 5 stars, 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. Ratings do not take into account sales loads.
