Second, this supplement updates certain information regarding the principal risks of the funds.
Effective immediately, the prospectuses and SAI are hereby revised as follows:
The section captioned “Fund summary” and sub‑captioned “Principal strategies—Principal investments” for the fund in each prospectus is revised by replacing the third paragraph in its entirety with the following:
The Fund will generally hold a portion of its assets in cash for operational purposes, including cash earning interest held at the fund’s custodian.

Risk associated with the fund holding cash: The fund will generally hold a portion of its assets in cash for operational purposes. Cash positions may hurt performance and may subject the fund to additional risks and costs, such as increased exposure to the custodian bank holding the assets and fees imposed for large cash balances. In addition, interest income received by the fund from cash held at the custodian would not qualify for the state and local income tax exemption applicable to certain dividends paid by the fund that are derived from interest income with respect to US government securities.
