Supplement to the currently effective Statements of Additional Information
("SAIs") for the above-listed funds.

The following information supplements information contained in "The Underlying
DWS Funds" section of the funds' SAIs:

DWS U.S. Bond Index Fund. The fund seeks to replicate, as closely as possible,
before the deduction of expenses, the performance of the Lehman Brothers U.S.
Aggregate Index, which emphasizes government mortgage-backed securities and
corporate investment grade debt securities. The fund pursues its objective by
investing primarily in the debt securities of the companies included in the
Lehman Brothers U.S. Aggregate Index and derivative instruments, such as futures
contracts and options, that provide exposure to the securities in the Lehman
Brothers U.S. Aggregate Index.

The above fund will also be added to the list of Underlying DWS Funds contained
in the SAIs for DWS LifeCompass Retirement Fund, DWS LifeCompass 2015 Fund, DWS
LifeCompass 2020 Fund, DWS LifeCompass 2030 Fund and DWS LifeCompass 2040 Fund.

The following information supplements information contained in the "Investment
Policies and Techniques of the Underlying DWS Funds" section of the funds' SAIs:

Fixed Income Security Risk. Fixed income securities generally expose the fund to
five types of risk: (1) interest rate risk (the potential for fluctuations in
bond prices due to changing interest rates); (2) income risk (the potential for
a decline in the fund's income due to falling market interest rates); (3) credit
risk (the possibility that a bond issuer will fail to make timely payments of
either interest or principal to the fund); (4) prepayment risk or call risk (the
likelihood that, during periods of falling interest rates, securities with high
stated interest rates will be prepaid, or "called" prior to maturity, requiring
the fund to invest the proceeds at generally lower interest rates); and (5)
extension risk (the likelihood that as interest rates increase, slower than
expected principal payments may extend the average life of fixed income
securities, which will have the effect of locking in a below-market interest
rate, increasing the security's duration and reducing the value of the
security).

Short-Term Instruments. When the fund experiences large cash inflows, for
example, through the sale of securities or of their shares and attractive
investments are unavailable in sufficient quantities, the fund may hold
short-term investments (or shares of money market mutual funds) for a limited
time pending availability of such investments.

Short-term instruments consist of foreign and domestic: (1) short-term
obligations of sovereign governments, their agencies, instrumentalities,
authorities or political subdivisions; (2) other investment grade short-term
debt securities; (3) investment grade commercial paper; (4) bank obligations,
including negotiable certificates of deposit, time deposits and bankers'
acceptances; and (5) repurchase agreements. At the time a fund invests in
commercial paper, bank obligations or repurchase agreements, the issuer or the
issuer's parent must have outstanding debt, commercial paper or bank obligations
rated investment grade; or, if no such ratings are available, the instrument

                                                              [DWS SCUDDER LOGO]
                                                             Deutsche Bank Group

must be deemed to be of comparable quality in the opinion of the portfolio
management team. These instruments may be denominated in US dollars or in
foreign currencies.

At the time the fund invests in commercial paper, bank obligations or repurchase
agreements, the issuer of the issuer's parent must have outstanding debt rated
AA or higher by S&P or Aa or higher by Moody's or outstanding commercial paper
or bank obligations rated A-1 by S&P or Prime-1 by Moody's; or, if no such
ratings are available, the instrument must be of comparable quality in the
opinion of the portfolio management team. These instruments may be denominated
in US dollars or in foreign currencies.

Obligations of Banks and Other Financial Institutions. The fund may invest in US
dollar-denominated fixed rate or variable rate obligations of US or foreign
financial institutions, including banks. Obligations of domestic and foreign
financial institutions in which the fund may invest include (but are not limited
to) certificates of deposit, bankers' acceptances, bank time deposits,
commercial paper, and other US dollar-denominated instruments issued or
supported by the credit of US or foreign financial institutions, including
banks.

For purposes of a fund's investment policies with respect to bank obligations,
the assets of a bank will be deemed to include the assets of its domestic and
foreign branches. Obligations of foreign branches of US banks and foreign banks
may be general obligations of the parent bank in addition to the issuing bank or
may be limited by the terms of a specific obligation and by government
regulation. The fund may invest in obligations of foreign banks or foreign
branches of US banks, which include banks located in the United Kingdom, Grand
Cayman Island, Nassau, Japan and Canada.

Investments in these obligations may entail risks that are different from those
of investments in obligations of US domestic banks because of differences in
political, regulatory and economic systems and conditions. These risks include
future political and economic developments, currency blockage, the possible
imposition of withholding taxes on interest payments, possible seizure or
nationalization of foreign deposits, difficulty or inability of pursuing legal
remedies and obtaining judgments in foreign courts, possible establishment of
exchange controls or the adoption of other foreign governmental restrictions
that might affect adversely the payment of principal and interest on bank
obligations. Foreign branches of US banks and foreign banks may also be subject
to less stringent reserve requirements and to different accounting, auditing,
reporting and record keeping standards than those applicable to domestic
branches of US banks.

Government Guaranteed Mortgage-Backed Securities. DWS U.S. Bond Index Fund's
investments in mortgage-backed securities may include securities issued or
guaranteed by the US government or one of its agencies, authorities,
instrumentalities or sponsored enterprises, such as Ginnie Mae, Fannie Mae and
Freddie Mac. There are several types of guaranteed mortgage-backed securities
currently available, including guaranteed mortgage pass-through certificates and
multiple class securities, which include guaranteed Real Estate Mortgage
Investment Conduit Certificates ("REMIC Certificates"), collateralized mortgage
obligations and stripped mortgage-backed securities. The fund is permitted to
invest in other types of mortgage-backed securities that may be available in the
future to the extent consistent with its investment policies and objective.

Ginnie Mae Certificates. DWS U.S. Bond Index Fund may purchase Ginnie Mae
Certificates. Ginnie Mae is a wholly owned corporate instrumentality of the
United States within the Department of Housing and Urban Development. The
National Housing Act of 1934, as amended (the "Housing Act"), authorizes Ginnie
Mae to guarantee the timely payment of the principal of and interest on
certificates that are based on and backed by a pool of mortgage loans insured by
the Federal Housing Administration under the Housing Act, or Title V of the
Housing Act of 1949 ("FHA Loans"), or guaranteed by the Department of Veterans
Affairs under the Servicemen's Readjustment Act of 1944, as amended ("VA
Loans"), or by pools of other eligible mortgage loans. The Housing Act provides
that the full faith and credit of the US government is pledged to the payment of
all amounts that may be required to be paid under any Ginnie Mae guaranty. In
order to meet its obligations under such guaranty, Ginnie Mae is authorized to
borrow from the US Treasury with no limitations as to amount.

                                       2
<PAGE>

The Ginnie Mae Certificates in which the fund may invest will represent a pro
rata interest in one or more pools of the following types of mortgage loans: (1)
fixed-rate level payment mortgage loans; (2) fixed-rate graduated payment
mortgage loans; (3) fixed-rate growing equity mortgage loans; (4) fixed-rate
mortgage loans secured by manufactured (mobile) homes; (5) mortgage loans on
multifamily residential properties under construction; (6) mortgage loans on
completed multifamily projects; (7) fixed-rate mortgage loans as to which
escrowed funds are used to reduce the borrower's monthly payments during the
early years of the mortgage loans ("buy down" mortgage loans); (8) mortgage
loans that provide for adjustments in payments based on periodic changes in
interest rates or in other payment terms of the mortgage loans; and (9)
mortgage-backed serial notes.

Fannie Mae Certificates. DWS U.S. Bond Index Fund may purchase Fannie Mae
Certificates. Fannie Mae is a federally chartered and privately owned
corporation organized and existing under the Federal National Mortgage
Association Charter Act of 1938. The obligations of Fannie Mae are not backed by
the full faith and credit of the US government. Each Fannie Mae Certificate will
represent a pro rata interest in one or more pools of FHA Loans, VA Loans or
conventional mortgage loans (i.e., mortgage loans that are not insured or
guaranteed by any governmental agency) of the following types: (1) fixed-rate
level payment mortgage loans; (2) fixed-rate growing equity mortgage loans; (3)
fixed-rate graduated payment mortgage loans; (4) variable rate mortgage loans;
(5) other adjustable rate mortgage loans; and (6) fixed-rate and adjustable
mortgage loans secured by multifamily projects.

Freddie Mac Certificates. DWS U.S. Bond Index Fund may purchase Freddie Mac
Certificates. Freddie Mac is a federally chartered and privately owned
corporation created pursuant to the Emergency Home Finance Act of 1970, as
amended (the "FHLMC Act"). The obligations of Freddie Mac are obligations solely
of Freddie Mac and are not backed by the full faith and credit of the US
government. Freddie Mac Certificates represent a pro rata interest in a group of
mortgage loans (a "Freddie Mac Certificate group") purchased by Freddie Mac. The
mortgage loans underlying the Freddie Mac Certificates will consist of
fixed-rate or adjustable rate mortgage loans with original terms to maturity of
between ten and thirty years, substantially all of which are secured by first
liens on one- to four-family residential properties or multifamily projects.
Each mortgage loan must meet the applicable standards set forth in the FHLMC
Act. A Freddie Mac Certificate group may include whole loans, participating
interests in whole loans and undivided interests in whole loans and
participations comprising another Freddie Mac Certificate group.

Stripped Mortgage-Backed Securities. DWS U.S. Bond Index Fund may purchase
stripped mortgage-backed securities ("SMBS"), which are derivative multi-class
mortgage securities. The market value of the class consisting entirely of
principal payments generally is unusually volatile in response to changes in
interest rates. The yields on a class of SMBS that receives all or most of the
interest from the mortgaged assets are generally higher than prevailing market
yields on other mortgage-backed securities because their cash flow patterns are
more volatile and there is a greater risk that the initial investment will not
be fully recouped. See "Illiquid Securities."

In accordance with a requirement imposed by the staff of the Securities and
Exchange Commission (the "SEC"), the portfolio management team will consider
privately issued fixed rate IOs and POs to be illiquid securities for purposes
of the Fund's limitation on investments in illiquid securities. Unless the
portfolio management team determines that a particular government-issued fixed
rate IO or PO is liquid, it will also consider these IOs and POs to be illiquid.

Adjustable Rate Mortgages-Interest Rate Indices. DWS U.S. Bond Index Fund may
invest in adjustable rate mortgages which may be adjusted on the basis of one of
several indices. The One Year Treasury Index is the figure derived from the
average weekly quoted yield on US Treasury securities adjusted to a constant
maturity of one year. The Cost of Funds Index reflects the monthly weighted
average cost of funds of savings and loan associations and savings banks whose
home offices are located in Arizona, California and Nevada (the "FHLB Eleventh
District") that are member institutions of the Federal Home Loan Bank of San
Francisco (the "FHLB of San Francisco"), as computed from statistics tabulated
and published by the FHLB of San Francisco. The FHLB of San Francisco normally
announces the Cost of Funds Index on the last working day of the month following
the month in which the cost of funds was incurred.

A number of factors affect the performance of the Cost of Funds Index and may
cause the Cost of Funds Index to move in a manner different from indices based
upon specific interest rates, such as the One Year Treasury Index.


                                       3

<PAGE>

Because of the various origination dates and maturities of the liabilities of
members of the FHLB Eleventh District upon which the Cost of Funds Index is
based, among other things, at any time the Cost of Funds Index may not reflect
the average prevailing market interest rates on new liabilities of similar
maturities. There can be no assurance that the Cost of Funds Index will
necessarily move in the same direction or at the same rate as prevailing
interest rates, since as longer term deposits or borrowings mature and are
renewed at market interest rates, the Cost of Funds Index will rise or fall
depending upon the differential between the prior and the new rates on such
deposits and borrowings. In addition, dislocations in the thrift industry in
recent years have caused and may continue to cause the cost of funds of thrift
institutions to change for reasons unrelated to changes in general interest rate
levels. Furthermore, any movement in the Cost of Funds Index as compared to
other indices based upon specific interest rates may be affected by changes
instituted by the FHLB of San Francisco in the method used to calculate the Cost
of Funds Index. To the extent that the Cost of Funds Index may reflect interest
changes on a more delayed basis than other indices, in a period of rising
interest rates, any increase may produce a higher yield later than would be
produced by such other indices, and in a period of declining interest rates, the
Cost of Funds Index may remain higher than other market interest rates which may
result in a higher level of principal prepayments on mortgage loans which adjust
in accordance with the Cost of Funds Index than mortgage loans which adjust in
accordance with other indices.

LIBOR, the London InterBank Offered Rate, is the interest rate that the most
creditworthy international banks dealing in US dollar-denominated deposits and
loans charge each other for large dollar-denominated loans. LIBOR is also
usually the base rate for large dollar-denominated loans in the international
market. LIBOR is generally quoted for loans having rate adjustments at one,
three, six or twelve month intervals.

Mortgage-Backed Securities and Asset-Backed Securities -- Types of Credit
Support. Mortgage-backed securities and asset-backed securities are often backed
by a pool of assets representing the obligations of a number of different
parties. To lessen the effect of failure by obligors on underlying assets to
make payments, such securities may contain elements of credit support. Such
credit support falls into two categories: (1) liquidity protection and (2)
protection against losses resulting from ultimate default by an obligor on the
underlying assets. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets, to ensure that the
pass-through of payments due on the underlying pool occurs in a timely fashion.
Protection against losses resulting from ultimate default enhances the
likelihood of ultimate payment of the obligations on at least a portion of the
assets in the pool. Such protection may be provided through guarantees,
insurance policies or letters of credit obtained by the issuer or sponsor from
third parties; through various means of structuring the transaction; or through
a combination of such approaches. The fund will not usually pay any additional
fees for such credit support, although the existence of credit support may
increase the price of a security.

The ratings of mortgage-backed securities and asset-backed securities for which
third-party credit enhancement provides liquidity protection or protection
against losses from default are generally dependent upon the continued
creditworthiness of the provider of the credit enhancement. The ratings of such
securities could be subject to reduction in the event of deterioration in the
creditworthiness of the credit enhancement provider even in cases where the
delinquency and loss experience on the underlying pool of assets is better than
expected.

Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments, sometimes funded from a portion of the
payments on the underlying assets, are held in reserve against future losses)
and "over-collateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceed those required to make payment of the
securities and pay any servicing or other fees). The degree of credit support
provided for each issue is generally based on historical information with
respect to the level of credit risk associated with the underlying assets.
Delinquency or losses in excess of that which is anticipated could adversely
affect the return on an investment in such a security.

Yankee Bonds. DWS U.S. Bond Index Fund may invest in Yankee bonds. Yankee Bonds
are US dollar-denominated bonds sold in the US by non-US issuers. As compared
with bonds issued in the US, such bond issues


                                       4
<PAGE>

normally carry an interest rate but are less actively traded. Investing in the
securities of foreign companies involves more risks than investing in securities
of US companies. Their value is subject to economic and political developments
in the countries where the companies operate and to changes in foreign currency
values. Values may also be affected by foreign tax laws, changes in foreign
economic or monetary policies, exchange control regulations and regulations
involving prohibitions on the repatriation of foreign currencies. In many
foreign countries, there is less publicly available information about foreign
issuers, and there is less government regulation and supervision of foreign
stock exchanges, brokers and listed companies. Also in many foreign countries,
companies are not subject to uniform accounting, auditing, and financial
reporting standards comparable to those applicable to domestic issuers. Security
trading practices and custody arrangements abroad may offer less protection to
the fund's investments and there may be difficulty in enforcing legal rights
outside the United States. Settlement of transactions in some foreign markets
may be delayed or may be less frequent than in the United States which could
affect the liquidity of the fund's portfolio. Additionally, in some foreign
countries, there is the possibility of expropriation or confiscatory taxation,
limitations on the removal of securities, property, or other fund assets,
political or social instability or diplomatic developments which could affect
investments in foreign securities. In addition, the relative performance of
various countries' fixed income markets historically has reflected wide
variations relating to the unique characteristics of each country's economy.
Year-to-year fluctuations in certain markets have been significant, and negative
returns have been experienced in various markets from time to time.

Yield Curve Options. DWS U.S. Bond Index Fund may enter into options on the
yield spread or yield differential between two securities. These options are
referred to as yield curve options. In contrast to other types of options, a
yield curve option is based on the difference between the yields of designated
securities, rather than the prices of the individual securities, and is settled
through cash payments. Accordingly, a yield curve option is profitable to the
holder if this differential widens (in the case of a call) or narrows (in the
case of a put), regardless of whether the yields of the underlying securities
increase or decrease.

Spreadlocks. DWS U.S. Bond Index Fund may enter into spreadlocks. A spreadlock
is a form of swap contract that involves an exchange of a one-time cash payment
based on a specific financial index between the fund and another party. A
spreadlock allows an interest rate swap user to lock in the forward differential
between the interest rate swap rate and the yield of the government bond
underlying the swap. Essentially, a spreadlock allows the investor to buy or
sell the spread forward by entering into a forward contract on the swap spread
(i.e., the spread between the government yield and the swap rate (or yield)) for
a given maturity. The price of a spreadlock is determined by the yield spread
between a forward starting fixed/floating swap and a forward transaction in a
government bond. The value of the swap is adjusted daily and the change in value
is recorded as unrealized appreciation or depreciation until the agreement
matures, at which time the cash payment, based on the value of the swap on the
maturity date, is exchanged between the two parties.
