The fund maintains certain minimum liquidity standards such that:
-
the fund may not purchase a security other than a security offering daily liquidity if, immediately after purchase, the fund would have invested less than 25% of its total assets in securities offering daily liquidity (includes securities that mature or are subject to demand within one business day, cash or direct US government obligations);
-
(For DWS Government & Agency Securities Portfolio, DWS Government Money Market Series and DWS Government Money Market VIP): the fund may not purchase a security other than a security offering weekly liquidity if, immediately after purchase, the fund would have invested less than 50% of its total assets in securities offering weekly liquidity (includes securities that mature or are subject to demand within five business days, cash, direct US government obligations and government agency discount notes with remaining maturities of 60 days or less);
-
(For DWS Treasury Portfolio): the fund may not purchase a security other than a security offering weekly liquidity if, immediately after purchase, the fund would have invested less than 50% of its total assets in securities offering weekly liquidity (includes securities that mature or are subject to demand within five business days, cash, direct US government obligations); and
-
the fund may not purchase an illiquid security if, immediately after purchase, the fund would have invested more than 5% of its total assets in illiquid securities (securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the market value ascribed to them by the fund).

Potential negative interest rates
In the event that the fund has a negative gross yield as a result of negative interest rates (a negative interest rate event), it may be challenging or impossible to maintain a stable net asset value (NAV) of $1.00 per share. However, regulations that govern the operation of money market funds permit the fund, if experiencing a negative interest rate event, to seek to continue to provide a stable NAV of $1.00 per share by using a Reverse Distribution Mechanism (RDM) which reduces the number of shares in proportion to the fund’s negative income. Shares may continue to have a NAV of $1.00 per share, but each shareholder would have fewer shares. The fund will use an RDM to cancel shares held by shareholders only if the fund’s Board determines that using an RDM is in the best interests of the fund and its shareholders.
If the fund chooses to use an RDM to cancel fund shares, the fund’s per-share NAV may remain stable, but shareholders will lose money as a result of the fund’s negative gross yield. In the event that shares are canceled, tax treatment of distributions and shareholder basis is uncertain. You should consult with your tax advisor to determine whether you will experience any negative tax consequences as a result of the fund’s use of an RDM. Account statements will include disclosure regarding share cancellations if an RDM is used.
