The following information supplements the "Management of Fund" section of each
Fund's Statements of Additional Information:


From time to time, Deutsche Bank or an affiliate (collectively, "DB") may at its
sole discretion invest its own assets in shares of the Fund ("proprietary
investment") for such purposes it deems appropriate, including investments
designed to assist in the management of the Fund's portfolio. Any proprietary
investment may be hedged and, in that event, the return on the proprietary
investment, net of the effect of the hedge, would be expected to differ from the
return of the Fund. DB has no obligation to make any proprietary investments and
the amount of any proprietary investment that is made may or may not be
significant in comparison to the level of assets of the Fund. In the event that
a proprietary investment is made, except as otherwise required under the
Investment Company Act of 1940, DB would be permitted to redeem the investment
at such time that it deems appropriate.
