                              ---------------------


DWS Large Company Growth Fund

The following information replaces similar disclosure in the "Compensation of
Portfolio Managers" subsection under the "Management of the Fund" section of the
Fund's Statements of Additional Information ("SAIs"):

Compensation of Portfolio Managers

Portfolio managers are eligible for total compensation comprised of base salary
and variable compensation.

Base Salary - Base salary is linked to job functions, responsibilities and
financial services industry peer comparison through the use of extensive market
data surveys.

Variable Compensation - Generally, variable compensation comprises a greater
proportion of total compensation as a portfolio manager's seniority and
compensation levels increase. Variable compensation may include a cash bonus
incentive, and potential participation in long-term incentive programs including
but not limited to, Deutsche Bank equity, equity linked vehicle, and restricted
cash. Variable compensation is determined based on an analysis of a number of
factors, including among other things, the performance of Deutsche Bank, the
performance of the Asset Management division, and the portfolio manager's
individual contribution. In evaluating individual contribution, management will
consider a combination of quantitative and qualitative factors. Top performing
investment professionals earn a total compensation package that is highly
competitive. As variable compensation increases, the percentage awarded in
long-term incentives also increases. Long-term incentives are subject to a
clawback provision for unvested portions only during the three-year life of the
plan should the individual engage in any conduct that is a significant breach of
DB policies and procedures.

o    The quantitative analysis of a portfolio manager's individual performance
     is based on, among other factors, performance of all of the accounts
     managed by the portfolio manager (which includes the fund and any other
     accounts managed by the portfolio manager) over a one-, three-, and
     five-year period relative to the appropriate Morningstar and Lipper peer
     group universes and/or benchmark index(es) with respect to each account.
     Additionally, the portfolio manager's retail/institutional asset mix is
     weighted, as appropriate for evaluation purposes. Generally the benchmark
     index used is a benchmark index set forth in the fund's prospectus to which
     the fund's performance is compared. Additional or different appropriate
     peer group or benchmark indices may also be used. Primary weight is given
     to pre-tax portfolio performance over three-year and five-year time periods
     (adjusted as appropriate if the portfolio manager has served for less than
     five years) with lesser consideration given to portfolio performance over a
     one-year period. The increase or decrease in a fund's assets due to the
     purchase or sale of fund shares is not considered a material factor.

o    The qualitative analysis of a portfolio manager's individual performance is
     based on, among other things, the results of an annual management and
     internal peer review process, and management's assessment of overall
     portfolio manager contributions to investor relations, the investment
     process and overall performance (distinct from fund and other account
     performance). Other factors, including contributions made to the investment
     team, as well as adherence to Compliance Policies and Procedures, Risk
     Management procedures, the firm's Code of Ethics and "living the values" of
     the Advisor are also factors.

The quantitative analysis of a portfolio manager's performance is given more
weight in determining variable compensation than the qualitative portion.

Conflicts of Interest

In addition to managing the assets of the Fund, the Fund's portfolio managers
may have responsibility for managing other client accounts of the Advisor or its
affiliates. The tables below show, for each portfolio manager, the number and
asset size of (1) SEC registered investment companies (or series thereof) other
than the Fund, (2) pooled investment vehicles that are not registered investment
companies and (3) other accounts (e.g., accounts managed for individuals or
organizations) managed by each portfolio manager. Total assets attributed to
each portfolio manager in the tables below include total assets of each account
managed by them, although the manager may only manage a portion of such
account's assets. The tables also show the number of performance based fee
accounts, as well as the total assets of the accounts for which the advisory fee
is based on the performance of the account. This information is provided as of
March 31, 2009.
