Fund Characteristics as of Mar 01 2021

Number of Holdings	Average Coupon Average Coupon The [market value] weighted average coupon of the bonds in a portfolio.	Average Maturity in Years Average Maturity The market value-weighted average maturity of the bonds and loans in a portfolio, where maturity is defined as the stated final for bullet maturity bonds and loans.	Average Price	Average Yield To Worst The lowest potential yield that can be received on a bond without the issuer actually defaulting. The YTW is calculated by making worst-case scenario assumptions on the issue by calculating the return that would be received if the issuer uses provisions, including prepayments. When aggregating YTW for a portfolio level statistic, the weighted average of the YTW and market value for each security is used.	Current Yield Current Yield A bond's annual return based on its annual coupon payments and current price (as opposed to its original price or face). The formula for current yield is a bond's annual coupons divided by its current price. When aggregating Current Yield for a portfolio level statistic, the weighted average of the Current Yield and market value for each security is used.	Option Adjusted Duration Option Adjusted Duration An option-adjusted measure of a bond's (or portfolio's) sensitivity to changes in interest rates calculated as the average percentage change in a bond's value (price plus accrued interest) under shifts of the Treasury curve +/- 100 bps. Incorporates the effect of embedded options for corporate bonds and changes in prepayments for mortgage-backed securities.

Performance quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, so you may have a gain or loss when shares are sold. Current performance may be higher or lower than that quoted. Performance of an index is not illustrative of any particular investment. It is not possible to invest directly in an index.

Performance returns for periods of less than one year are not annualized. Performance is shown net of fees.

The market price used to calculate the Market Value return is the midpoint between the highest bid and the lowest offer on the exchange on which the shares of the Fund are listed for trading, as of the time that the Fund's NAV is calculated. If you trade your shares at another time, your return may differ.
