Factors Affecting Performance [Text Block]

(a) KraneShares CSI Overseas China Internet ETF (KWEB)

 

 

The Fund aims to provide, before fees and expenses, the total return of KWEB up to a 40.01% Cap while providing a 90% buffer against losses over the Outcome Period of January 27, 2025, to January 15, 2027.

 

The put options held by the Fund during the period contributed the most to the Fund’s return. China’s internet equities underperformed the broader Chinese equity market, as defined by the MSCI China All Shares Index, due to intense competition in China's E-Commerce industry, which weighed on the margins of large-cap e-commerce firms, as well as geopolitical headwinds.

This is a summary of certain changes to the Fund since April 1, 2025. For more complete information, you may review the Fund’s prospectus, which is available at https://kraneshares.com/etf/kbuf/#fund-documents or upon request at 1-855-857-2638.

 

Krane Funds Advisors, LLC (“Krane” or the “Adviser”), the investment adviser to the Fund, entered into an agreement whereby its officers and employees, among others, through KFA Two Holdings, LLC, will acquire a majority interest in the Adviser from China International Capital Corporation (USA) Holdings Inc., a wholly-owned, indirect subsidiary of China International Capital Corporation Limited (the “Transaction”). Consummation of the Transaction will, under the Investment Company Act of 1940, result in the automatic termination of the Fund’s existing investment advisory and, if applicable, sub-advisory agreements. In anticipation of the Transaction, the Board approved new advisory and, if applicable, sub-advisory agreements on terms identical to the existing agreements (other than effective and termination dates), subject to shareholder approval of the new advisory agreement. The new sub-advisory agreement will take effect in reliance on a manager-of-managers exemptive order. To ensure continuity of management pending shareholder approval of the new advisory agreement, the Board also approved interim advisory and, if applicable, sub-advisory agreements, effective upon closing of the Transaction, each with terms substantially identical to the current agreements, to remain in effect for up to 150 days while shareholder approval is sought.
