Supplement dated April 1, 2022 (the “Supplement”)

to the Summary Prospectus, Prospectus and/or Statement of Additional Information (“SAI”) as applicable,

for each series listed in Appendix A, Appendix B, and Appendix C

(each, a “Fund” and together, the “Funds”)

The information in this Supplement updates information in, and should be read in conjunction with, each Fund’s Summary Prospectus, Prospectus, or SAI, as applicable.

The Index Provider for the Underlying Index of one or more Underlying Funds for the Funds listed in Appendix A and Appendix B and the Index Provider for each of the Funds listed in Appendix C, removed Russian debt securities from each Underlying Index on March 31, 2022.

Effective immediately, each Fund’s Summary Prospectus, Prospectus and SAI, as applicable, is amended as follows:

Change in a Fund’s “Summary of Principal Risks”

The last sentence in the section of the Summary Prospectus and Prospectus for each Fund listed in Appendix C entitled “Tracking Error Risk” in the section entitled “Summary of Principal Risks” is hereby deleted in its entirety and replaced with the following:

BFA EXPECTS THAT THE FUND WILL EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

The following is hereby added to the section of the Prospectus and Summary Prospectus entitled “Summary of Principal Risks” for BYLD:

Tracking Error Risk. The Fund may be subject to “tracking error,” which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the

distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements, among other reasons. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Change in a Fund’s “Principal Investment Strategies”

The reference to “Russia” in the fourth paragraph in the section of the Summary Prospectus and Prospectus for LEMB entitled “Principal Investment Strategies” is hereby deleted in its entirety.
