Supplement dated May 3, 2022 to the currently effective Statements of Additional Information (each, an “SAI”),

as may be supplemented from time to time

Effective immediately, the following discussion is added to the “INVESTMENT POLICIES” section in each SAI:

INVESTMENTS IN VARIABLE INTEREST ENTITY STRUCTURES

The Funds may gain investment exposure to certain Chinese companies through variable interest entity (“VIE”) structures. Such investments are subject to the investment risks associated with the Chinese-based company. The VIE structure enables foreign investors, such as the Funds, to obtain investment exposure to a Chinese company in situations in which the Chinese government has limited or prohibited non-Chinese ownership of such company. The VIE structure does not involve direct equity ownership in a China-based company, but rather involves claims to the China-based company’s profits and control of the assets that belong to the China-based company through contractual arrangements. The contractual arrangements in place with the China-based company provide limited ability to exercise control over the China-based company and the China-based company’s actions may negatively impact the value of an investment through a VIE structure. Control may also be jeopardized if a natural person who holds an equity interest in the China-based company breaches the terms of the contractual arrangements or is subject to legal proceedings, or if any physical instruments such as chops and seals are used without authorization.

Intervention by the Chinese government with respect to the VIE structure could significantly affect the Chinese operating company’s performance and thus, the value of a Fund’s investment through a VIE structure, as well as the enforceability of the contractual arrangements of the VIE structure. In the event of such an occurrence, a Fund, as a foreign investor, may have little or no legal recourse. If the Chinese government were to determine that the contractual arrangements establishing the VIE structure did not comply with Chinese law or regulations, the Chinese operating company could be subject to penalties, revocation of its business and operating license, or forfeiture of ownership interests. In addition to the risk of government intervention, investments through a VIE structure are subject to the risk that the China-based company (or its officers, directors, or Chinese equity owners) may breach the contractual arrangements, or Chinese law changes in a way that adversely affects the enforceability of the arrangements, or the contracts are otherwise not enforceable under Chinese law, in which case a Fund may suffer significant losses on its investments through a VIE structure with little or no recourse available.
