Supplement to the currently effective Statements of Additional Information for
the below listed portfolio:

DWS Money Market VIP


The following replaces similar disclosure in the "Net Asset Value" section of
the Portfolio's Statements of Additional Information:

DWS Money Market VIP values its portfolio instruments at amortized cost, which
does not take into account unrealized capital gains or losses. This involves
initially valuing an instrument at its cost and thereafter assuming a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price the
Portfolio would receive if it sold the instrument. Calculations are made to
compare the value of the Portfolio's investments valued at amortized cost with
market values. Market valuations are obtained by using actual quotations
provided by market makers, estimates of market value, or values obtained from
yield data relating to classes of money market instruments published by
reputable sources at the mean between the bid and asked prices for the
instruments. In accordance with Board approved procedures, in the event market
quotations are not readily available for certain portfolio assets, for purposes
of the market value comparison, the fair value of such portfolio assets will be
determined by the Portfolio's Pricing Committee (or, in some cases, the Board's
Valuation Committee). If a deviation of 1/2 of 1% or more were to occur between
the net asset value per share calculated by reference to market values and the
Portfolio's $1.00 per share net asset value, or if there were any other
deviation that the Board of Trustees of the Portfolio believed would result in a
material dilution to shareholders or purchasers, the Board of Trustees would
promptly consider what action, if any, should be initiated. If the Portfolio's
net asset value per share (computed using market values) declined, or were
expected to decline, below $1.00 (computed using amortized cost), the Board of
Trustees of the Portfolio might temporarily reduce or suspend dividend payments
in an effort to maintain the net asset value at $1.00 per share. As a result of
such reduction or suspension of dividends or other action by the Board of
Trustees, an investor would receive less income during a given period than if
such a reduction or suspension had not taken place. Such action could result in
investors receiving no dividend for the period during which they hold their
shares and receiving, upon redemption, a price per share lower than that which
they paid. On the other hand, if the Portfolio's net asset value per share
(computed using market values) were to increase, or were anticipated to increase
above $1.00 (computed using amortized cost), the Board of Trustees of the
Portfolio might supplement dividends in an effort to maintain the net asset
value at $1.00 per share. Redemption orders received in connection with the
administration of checkwriting programs by certain dealers or other financial
services firms prior to the determination of the Portfolio's net asset value
also may be processed on a confirmed basis in accordance with the procedures
established by DIDI.
