section of each fund's Statement of Additional Information:

For DWS Strategic Government Securities Fund and DWS Strategic Income Fund only:

For purposes of the Combined Purchases, Letter of Intent and Cumulative Discount
features described above, employer sponsored employee benefit plans using the
Flex subaccount record keeping system available through ADP, Inc. under an
alliance with DIDI and its affiliates may include: (a) Money Market Funds as
"DWS Funds," (b) all classes of shares of any DWS Fund and (c) the value of any
other plan investments, such as guaranteed investment contracts and employer
stock, maintained on such subaccount record keeping system. Once eligible plan
assets under this provision reach the $250,000 threshold, a later decline in
assets below the $250,000 threshold will not affect the plan's ability to
continue to purchase Class A shares at net asset value.
