pursuant to paragraph 2(b) of Instruction B of the General Instructions to Form
N-1A.

ITEM 4. INVESTMENT OBJECTIVES, PRINCIPAL INVESTMENT STRATEGIES AND RELATED
        RISKS.

(a)      INVESTMENT OBJECTIVES.

The LARGE CAP GROWTH SERIES, the WT LARGE CAP GROWTH SERIES and the SMALL CAP
CORE SERIES each seek superior long-term growth of capital. The LARGE CAP CORE
SERIES, the LARGE CAP VALUE SERIES, the MID CAP VALUE SERIES and the SMALL CAP
VALUE SERIES each seek to achieve long-term capital appreciation. The
INTERNATIONAL MULTI-MANAGER SERIES seeks superior long-term capital
appreciation. The SHORT/INTERMEDIATE BOND SERIES and the INTERMEDIATE BOND
SERIES each seek a high total return, consistent with high current income. The
MUNICIPAL BOND SERIES seeks a high level of income exempt from federal income
tax, consistent with the preservation of capital. The PRIME MONEY MARKET SERIES,
the U.S. GOVERNMENT Series and PREMIER MONEY MARKET SERIES each seek a high
level of current income consistent with the preservation of capital and
liquidity. The TAX-EXEMPT SERIES seeks as high a level of interest income exempt
from federal income tax as is consistent with preservation of principal. The
investment objectives for each Series except Large Cap Core Series may not be
changed without shareholder approval. The Prime Money Market, U.S. Government,
Premier Money Market and Tax-Exempt Series are money market funds and intend to
maintain a stable $1 share price, although this may not be possible under
certain circumstances. There is no guarantee that a Series will achieve its
investment objective.

For purposes of these investment objectives, "superior" long-term growth of
capital means to exceed the long-term growth of capital from an investment in
the securities comprising the S&P 500 Index (for the Large Cap Growth , WT Large
Cap Growth, Large Cap Core and Large Cap Value Series); the Russell 2000 Index,
(for the Small Cap Core, and the Small Cap Value Series); and the Russell Mid
Cap Index (for the Mid Cap Value Series), the Morgan Stanley Capital
International Europe, Australasia and Far East Index (for the International
Multi-Manager Series).

(b)      IMPLEMENTATION OF INVESTMENT OBJECTIVES.

EQUITY SERIES
<PAGE>

The LARGE CAP GROWTH SERIES and WT LARGE CAP GROWTH SERIES are managed in an
identical manner. Each Series invests, under normal market conditions, at least
65% of its total assets in the following equity (or related) securities:
o common stocks of U.S. corporations that are judged by the adviser to have
  strong growth characteristics and, with respect to at least 65% of the Series'
  total assets, have a market capitalization of $2 billion or higher at the time
  of purchase;
o options on, or securities convertible (such as convertible preferred stock and
  convertible bonds) into, the common stock of U.S. corporations described
  above;
o options on indexes of the common stock of U.S. corporations described above;
   and
o contracts for either the future delivery, or payment in respect of the future
  market value, of certain indexes of the common stock of U.S. corporations
  described above, and options upon such futures contracts.

The adviser of each Series looks for high quality, sustainable growth stocks
while paying careful attention to valuation. Research is bottom-up, emphasizing
business fundamentals, including financial statement analysis and industry and
competitor evaluations. The adviser selects stocks it believes exhibit
consistent, above-average earnings growth, superior quality and attractive
risk/reward characteristics. These dominant companies are expected to generate
consistent earnings growth in a variety of economic environments.

The adviser also seeks to provide a greater margin of safety and stability in
each Series. Superior earnings growth is expected to translate ultimately into
superior compounding of returns. Additionally, several valuation tools are used
to avoid over-paying for growth or chasing "hot" stocks. Over time, the adviser
believes these favorable characteristics will produce superior returns with less
risk than many growth styles.

The adviser's research team analyzes a broad universe of over 2,000 companies.
Industry specialists search for high-quality companies growing at roughly double
the market's average. Approximately 150 stocks pass these initial screens and
are subject to thorough research. Dominant market share, strong financials, the
power to price, significant free cash flow and shareholder-oriented management
are critical variables.

Final purchase candidates are selected by the adviser's investment committee
based on attractive risk/reward characteristics and diversification guidelines.
Certain industries may be over or under-weighted by the adviser based upon
favorable growth rates or valuation parameters.

The adviser attempts to maintain portfolio continuity by purchasing sustainable
growth companies that are less sensitive to short-term economic trends than
cyclical, low quality companies. The adviser generally sells stocks when the
risk/reward characteristics of a stock turn negative, company fundamentals
deteriorate, or the stock underperforms the market or its peer group. The latter
device is employed to minimize mistakes and protect capital.

Each Series combines three distinct components, each of which is intended to
enhance returns and add balance.

LARGE CAP GROWTH STOCKS (over $5 billion in total market cap) - Up to 100%, but
not less than 65%, of each Series' total assets:
o Mature, predictable businesses
o Capital appreciation and income
o Highest liquidity

MEDIUM CAP GROWTH STOCKS (between $1 and $5 billion in total market cap) - Up to
20% of each Series' total assets:

                                      A-2
<PAGE>

o Superior long-term potential
o Strong niche or franchise
o Seasoned management

SPECIAL SITUATIONS GROWTH OPPORTUNITIES - Up to 20% of each Series' total
assets:
o Stable return, independent of the market
o Unusually favorable risk/reward characteristics
o Typically involve corporate restructuring

In order to respond to adverse market, economic, political or other conditions,
each Series may assume a temporary defensive position and invest without limit
in commercial paper and other money market instruments that are rated investment
grade. The result of this action may be that a Series will be unable to achieve
its investment objective.

The LARGE CAP CORE SERIES invests, under normal market conditions, at least 65%
of its total assets in the following equity (or related) securities:
o securities of U.S. corporations that are judged by the adviser to have strong
  growth and valuation characteristics;
o options on, or securities convertible (such as convertible preferred stock and
  convertible bonds) into, the common stock of U.S. corporations described
  above;
o receipts or American Depositary Receipts ("ADRs"), which are typically issued
  by a U.S. bank or trust company as evidence of ownership of underlying
  securities issued by a foreign corporation; and
o cash reserves and money market instruments (including securities issued or
  guaranteed by the U.S. Government, its agencies or instrumentalities,
  repurchase agreements, certificates of deposit and bankers' acceptances issued
  by banks or savings and loan associations, and commercial paper).

The Large Cap Core Series is a diversified portfolio of U.S. equity (or related)
securities, including common stocks, preferred stocks and securities convertible
into common stock of companies with market capitalizations of at least $2
billion. Dividend income is an incidental consideration compared to growth in
capital in the selection of securities. The adviser seeks securities that
possess strong growth and value characteristics based on the evaluation of the
issuer's background, industry position, historical returns and the experience
and qualifications of the management team. The adviser may rotate the Series'
holdings among various market sectors based on economic analysis of the overall
business cycle.

As a temporary defensive investment policy, the Large Cap Core Series may invest
up to 100% of its assets in money market instruments and other short-term debt
instruments, rated investment grade or higher at the time of purchase, and may
hold a portion of its assets in cash. The result of this action may be that the
Series will be unable to achieve its investment objective.

The SMALL CAP CORE SERIES invests, under normal market conditions, at least 65%
of its total assets in the following equity (or related) securities:
o common stocks of U.S. corporations that are judged by the adviser to have
  strong growth characteristics or to be undervalued in the marketplace relative
  to underlying profitability and have a market capitalization of less than $2
  billion at the time of purchase;
o options on, or securities convertible (such as convertible preferred stock and
  convertible bonds) into, the common stock of U.S. corporations described
  above;
o options on indexes of the common stock of U.S. corporations described above;
  and
o contracts for either the future delivery, or payment in respect of the future
  market value, of certain indexes of the common stock of U.S. corporations
  described above, and options upon such futures contracts.

The Small Cap Core Series is a diversified portfolio of small cap U.S. equity
(or related) securities with a market capitalization of $2 billion or less at
the time of purchase. To achieve the Series' objective of long-term growth of
capital, the Series' adviser employs a combined growth and value investment
approach.

                                      A-3
<PAGE>

The adviser uses proprietary quantitative research techniques to find
companies with long-term growth potential or that seem undervalued. After
analyzing those companies, the adviser invests the Series' assets in the stocks
of companies with the most attractive combination of long-term earnings, growth
and valuation. Securities will be sold to make room for new companies with
superior growth, valuation and projected return characteristics or to preserve
capital where the original assessment of the company's growth prospects and
earnings power has not proven optimistic.

In the Series' efforts to achieve its investment objective, it seeks to
outperform the Russell 2000 Index (assuming a similar investment in the
securities comprising this index would reinvest dividends and capital gains
distributions). The Russell 2000 Index is a passive index of the smallest 2000
stocks in the Russell 3000 Index of the 3000 largest stocks in the U.S. as
measured by market capitalization.

The INTERNATIONAL MULTI-MANAGER SERIES invests, at all times, at least 85% of
its total assets in the following equity (or related) securities:
o common stocks of foreign issuers;
o preferred stocks and/or debt securities that are convertible securities of
  such foreign issuers; and o open or closed-end investment companies (mutual
  funds) that invest primarily in the equity securities of issuers in countries
  where it is impossible or impractical to invest directly.

The International Multi-Manager Series is a diversified portfolio of equity
securities (including convertible securities) of issuers located outside of the
United States. The Series may use forward currency contracts, options, futures
contracts and options on futures contracts to attempt to hedge actual or
anticipated investment security positions. Three sub-advisers, Clemente Capital,
Inc., Invista Capital Management Inc., and Scudder Kemper Investments, Inc.,
manage the assets of the Series. The adviser allocates the Series' assets among
each sub-adviser in roughly equal portions and then allows each sub-adviser to
use its own investment approach and strategy to achieve the Series' objective.

Clemente's investment approach begins with a global outlook, identifying the
major forces (i.e., political events, social developments, trade and capital
flows) affecting the global environment and then identifying the themes (i.e.,
corporate restructuring, infrastructure spending, consumer's coming of age) that
are responding to the major forces. The third step is to decide which countries
or sectors will benefit from these themes and then seek companies with favorable
growth characteristics in those countries or sectors. The next steps are to
research and identify specific holdings and ongoing monitoring and evaluation of
the Series. Series holdings are sold when shares reach the target price, the
fundamentals of a company have deteriorated or when new companies with superior
growth and valuation characteristics have been identified.

Invista's investment approach focuses on identifying opportunities through a
fundamentally sound, economic value driven process applied evenly across all
international markets. Candidates for purchase are companies whose current price
is substantially below investment value as determined by Invista's estimate of
future free cash flows. Once this evaluation process is applied, purchases are
made among those companies that provide optimal combinations of valuation,
growth and risk. Series holdings are sold when the relative attractiveness of a
security is not as great as additions proposed by a member of the investment
team.

Scudder Kemper's investment approach involves a top-down/bottom-up approach with
a focus on fundamental research. Investment ideas are generated by regional
analysts, global industry analysts and portfolio managers through the
integration of three analytical disciplines; global themes (identification of
sectors and industries likely to gain or lose during specific phases of a
theme's cycle); country analysis (quantitative assessment of each country's
fundamental and political characteristics combined with an objective,
quantitative analysis of market and economic data); and company analysis
(identification of company opportunities by searching for unique attributes such
as franchise or monopoly, above average growth potential, innovation or
scarcity). Series holdings are sold when the analysts indicate that the
underlying fundamentals are no longer strong.


                                      A-4
<PAGE>

The Series utilizes this multiple sub-adviser arrangement to reduce volatility
through multiple investment approaches, a strategy used by many institutional
investors. For example, a particular investment approach used by a sub-adviser
may be successful in a bear (falling) market, while another investment approach
used by a different sub-adviser may be more successful in a bull (rising)
market. The multiple investment approach is designed to soften the impact of a
single sub-adviser's performance in a market cycle during which that
sub-adviser's investment approach is less successful. Because each sub-adviser
has different investment approaches, the performance of one or more of the
sub-advisers is expected to offset the impact of any other sub-adviser's poor
performance, regardless of the market cycle. Unfortunately, this also works the
opposite way. The successful performance of a sub-adviser will be diminished by
the less successful performances of the other sub-advisers. There can be no
guarantee that the expected advantages of the multiple adviser technique will be
achieved.

In the Series' efforts to achieve its investment objective, it seeks to
outperform the Morgan Stanley Capital International Europe, Australasia & Far
East ("EAFE") Index (assuming a similar investment in the securities comprising
this index would reinvest dividends and capital gains distributions). The EAFE
Index is an unmanaged index comprised of the stocks of approximately 1100
companies, screened for liquidity, cross ownership and industry representation
and listed on major stock exchanges in Europe, Australasia and the Far East.

THE VALUE SERIES: The Large Cap Value, Mid Cap Value and Small Cap Value Series
seek to invest in stocks that are less expensive than comparable companies, as
determined by price/earnings ratios, cash flows or other measures. Value
investing therefore may reduce risk while offering potential for capital
appreciation as a stock gains favor among other investors and its price rises.

The Series are managed using investment ideas that the adviser has used for over
twenty-five years. The Series' adviser relies on selecting individual stocks and
does not try to predict when the stock market might rise or fall. It seeks out
those stocks that are undervalued and, in some cases, neglected by financial
analysts. The adviser evaluates the degree of analyst recognition by monitoring
the number of analysts who follow the company and recommend its purchase or sale
to investors.

The adviser starts by identifying early change in a company's operations,
finances or management. The adviser is attracted to companies which will look
different tomorrow - operationally, financially, managerially - when compared to
yesterday. This type of dynamic change often creates confusion and
misunderstandings and may lead to a drop in the company's stock price. Examples
of change include mergers, acquisitions, divestitures, restructuring, change of
management, new market/product/means of production/distribution, regulatory
change, etc. Once change is identified, the adviser evaluates the company on
several levels. It analyzes:
o Financial models based principally upon projected cash flows
o The price of the company's stock in the context of what the market is willing
  to pay for stock of comparable companies and what a strategic buyer would pay
  for the whole company
o The extent of management's ownership interest in the company
o The company's market by corroborating its observations and assumptions by
  meeting with management, customers and suppliers

The adviser also evaluates the degree of recognition of the business by the
investors by monitoring the number of sell side analysts who closely follow the
company and the nature of the shareholder base. Before deciding to purchase a
stock, the adviser conducts an extensive amount of business due diligence to
corroborate its observations and assumptions.

The identification of change comes from a variety of sources including the
private capital network which the adviser has established among its clients,
historical investments and intermediaries. The adviser also makes extensive use
of clipping services and regional brokers and bankers to identify elements of
change.

                                      A-5
<PAGE>

 The investment professionals regularly meet companies around the country
and sponsor more than 200 company/management meetings in its New York office.

By reviewing historical relationships and understanding the characteristics of a
business, the adviser establishes valuation parameters using relative ratios or
target prices. In its overall assessment, the adviser seeks stocks that it
believes have a greater upside potential than downside risk over an 18 to
24-month holding period.

An important function of the adviser is to set a price target, that is, the
price at which the stock will be sold when there has been no fundamental change
in the investment case. The adviser constantly monitors the companies held by
the Series to determine if there have been any fundamental changes in the
reasons that prompted the initial purchase of the stock. If significant changes
for the better have not materialized, the stock will be sold. The initial
investment case for stock purchase, which has been documented, is examined by
the adviser's investment professionals. A final decision on selling the stock is
made after all such factors are analyzed.

The LARGE CAP VALUE SERIES invests, under normal conditions, at least 65% of its
total assets in the following equity (or related) securities:
o common stocks of U.S. corporations that are judged by the adviser to be
  undervalued in the marketplace relative to underlying profitability and have a
  market capitalization of $10 billion or higher at the time of purchase; o
  options on, or securities convertible (such as convertible preferred stock and
  convertible bonds) into, the common stock of U.S. corporations described
  above;
o options on indexes of the common stock of U.S. corporations described above;
o contracts for either the future delivery, or payment in respect of the future
  market value, of certain indexes of the common stock of U.S. corporations
  described above, and options upon such futures contracts; and
o without limit in commercial paper and other money market instruments rated in
  one of the two highest rating categories by a nationally recognized
  statistical rating organization ("NRSRO"), in response to adverse market
  conditions, as a temporary defensive position. The result of this action may
  be that the Series will be unable to achieve its investment objective.

The Large Cap Value Series is a diversified portfolio of large cap U.S. equity
(or related) securities that are deemed by the adviser to be undervalued as
compared to the company's profitability potential.

The MID CAP VALUE SERIES invests, under normal conditions, at least 65% of its
total assets in the following equity (or related) securities:
o common and preferred stocks of U.S. corporations that are judged by the
  adviser to be undervalued in the marketplace relative to underlying
  profitability and have a market capitalization between $1 and $10 billion at
  the time of purchase;
o securities convertible (such as convertible preferred stock and convertible
  bonds) into, the common stock of U.S. corporations described above;
o warrants; and
o without limit in commercial paper and other money market instruments rated in
  one of the two highest rating categories by a NRSRO, in response to adverse
  market conditions, as a temporary defensive position. The result of this
  action may be that the Series will be unable to achieve its investment
  objective.

The Mid Cap Value Series is a diversified portfolio of medium cap U.S. equity
(or related) securities that are deemed by the adviser to be undervalued as
compared to the company's profitability potential.

The SMALL CAP VALUE SERIES invests, under normal conditions, at least 65% of its
total assets in the following equity (or related) securities:
o common and preferred stocks of U.S. corporations that are judged by the
  adviser to be undervalued in

                                      A-6
<PAGE>

  the marketplace relative to underlying profitability and have a market
  capitalization of $1 billion or less at the time of purchase;
o securities convertible (such as convertible preferred stock and convertible
  bonds) into, the common stock of U.S. corporations described above;
o warrants; and
o without limit in commercial paper and other money market instruments rated in
  one of the two highest rating categories by a NRSRO, in response to adverse
  market conditions, as a temporary defensive position. The result of this
  action may be that the Series will be unable to achieve its investment
  objective.

The Small Cap Value Series is a diversified portfolio of large cap U.S. equity
(or related) securities that are deemed by the adviser to be undervalued as
compared to the company's profitability potential.

ALL EQUITY SERIES. The frequency of portfolio transactions and a Series'
turnover rate will vary from year to year depending on the market. Increased
turnover rates incur the cost of additional brokerage commissions and may cause
recognition of greater capital gains. Series turnover rate is normally expected
to be less than 100% for each of the Series.

Each Series also may use other strategies and engage in other investment
practices, which are described in detail in Part B.

FIXED INCOME SERIES

The SHORT/INTERMEDIATE BOND SERIES:
o will invest at least 85% of its total assets in various types of investment
  grade fixed income securities;
o may invest up to 10% of its total assets in investment grade fixed income
  securities of foreign issuers;
o will, as a matter of fundamental policy, maintain a short-to-intermediate
  average duration (2 1/2 to 4 years); and
o the average dollar-weighted duration of securities held by the
  Short/Intermediate Bond Series will normally fall within a range of 2 1/2 to 4
  years.

The INTERMEDIATE BOND SERIES:
o will invest at least 85% of its total assets in various types of investment
  grade fixed income securities;
o may invest up to 10% of its total assets in investment grade fixed income
  securities of foreign issuers;
o will, as a matter of fundamental policy, maintain an intermediate average
  duration (4 to 7 years); and
o the average dollar-weighted duration of securities held by the Intermediate
  Bond Series will normally fall within a range of 4 to 7 years.

The MUNICIPAL BOND SERIES:
o will, as a fundamental policy, invest substantially all (at least 80%) of its
  net assets in a diversified portfolio of municipal securities that provide
  interest that is exempt from federal income tax;
o may invest up to 20% of its net assets in other types of fixed income
  securities that provide income that is subject to federal tax; and
o will, as a matter of fundamental policy, maintain an intermediate average
  duration (4 to 8 years); and
o the average dollar-weighted duration of securities held by the Municipal Bond
  Series will normally fall within a range of 4 to 8 years.

The Municipal Bond Series may not invest more than 25% of its total assets in
any one industry. Governmental issuers of municipal securities are not
considered part of any industry. The 25% limitation applies to municipal
securities backed by the assets and revenues of non-governmental users, such as
private operators of educational, hospital or housing facilities. However, the
investment adviser may decide that the yields available from concentrating in
obligations of a particular market sector or political subdivision justify the
risk that the performance of the Municipal Bond Series may be adversely affected
by such concentration. Under such market conditions, the Municipal Bond Series
may invest more than

                                      A-7
<PAGE>


25% of its assets in sectors of the municipal securities market, such as health
care or housing, or in securities relating to one political subdivision, such as
a given state or U.S. territory. Under these conditions, the Municipal Bond
Series' vulnerability to any special risks that affects that sector or
jurisdiction could have an adverse impact on the value of an investment in the
Series. There are no limitations on the Municipal Bond Series' investment in any
one of the three general categories of municipal obligations: general obligation
bonds, revenue (or special) obligation bonds and private activity bonds.

SERIES COMPOSITION. The composition of each Series' holdings varies, depending
upon the investment adviser's analysis of the fixed income markets, the
municipal securities market and the expected trends in those markets. The
securities purchased by the Series may be purchased based upon their yield, the
income earned by the security, or their potential capital appreciation, the
potential increase in the security's value, or both. The investment adviser
seeks to protect the Series' principal value by reducing fluctuations in value
relative to those that may be experienced by fixed income funds with a longer
average duration. This strategy may reduce the level of income attained by the
Series. There is no guarantee that principal value can be protected during
periods of extreme interest volatility.

The Series invest only in securities that are rated, at the time of purchase, in
the top four categories by a rating agency such as Moody's Investors Service,
Inc. or Standard & Poor's. If the securities are not rated, then the adviser
must determine that they are of comparable quality.

Each Series also may use other strategies and engage in other investment
practices, which are described in detail in Part B. The investments and
strategies listed above and described throughout this prospectus are those that
we use under normal market conditions.

MONEY MARKET SERIES

The PRIME MONEY MARKET SERIES invests in:
o U.S. dollar-denominated obligations of major U.S. and foreign banks and their
  branches located outside of the United States, of U.S. branches of foreign
  banks, of foreign branches of foreign banks, of U.S. agencies of foreign banks
  and wholly-owned banking subsidiaries of foreign banks;
o high quality commercial paper and corporate obligations;
o U.S. Government obligations;
o high quality municipal securities; and
o repurchase agreements that are fully collateralized by U.S. Government
  obligations.

U.S. Government obligations are debt securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities.

The U.S. GOVERNMENT SERIES invests at least 65% of its total assets in:
o U.S. Government obligations; and
o repurchase agreements that are fully collateralized by such obligations.

The PREMIER MONEY MARKET SERIES invests in:

o U.S. dollar-denomination obligations of major U.S. and foreign banks and their
  branches located outside of the United States, of U.S. branches of foreign
  banks, of foreign branches of foreign banks, of U.S. agencies of foreign banks
  and wholly-owned banking subsidiaries of foreign banks;
o commercial paper rated, at the time of purchase, in the highest category of
  short-term debt ratings of any two nationally recognized statistical rating
  organizations ("NRSRO");
o corporate obligations having a remaining maturity of 397 calendar days or
  less, issued by corporations having outstanding comparable obligations that
  are (a) rated in the two highest categories of any two NRSROs or (b) rated no
  lower than the two highest long-term debt ratings categories by any NRSRO.
o U.S. Government obligations;
o high quality municipal securities; and

                                      A-8
<PAGE>

o repurchase agreements that are fully collateralized by U.S. Government
  obligations.

The TAX-EXEMPT SERIES invests in:
o high quality municipal obligations and municipal bonds;
o floating and variable rate obligations;
o participation interests;
o high quality tax-exempt commercial paper; and o high quality short-term
  municipal notes.

The Tax-Exempt Series has adopted a policy that, under normal circumstances, at
least 80% of its annual income will be exempt from federal income tax.
Additionally, at least 80% of its annual income will not be a tax preference
item for purposes of the federal alternative minimum tax.

High quality securities include those that (1) are rated in one of the two
highest short-term rating categories by two NRSROs, such as S&P, Moody's and
Fitch IBCA (or by one NRSRO if only one NRSRO has issued a rating) or; (2) if
unrated are issued by an issuer with comparable outstanding debt that is rated
or are otherwise unrated and determined by the investment adviser to be of
comparable quality.

Each Series also may invest in other securities, use other strategies and engage
in other investment practices, which are described in detail in Part B.

(c)      RISKS.

The following is a list of certain risks that may apply to an investment in a
Series, unless otherwise indicated. Further information about investment risks
is available in Part B:

o CREDIT RISK: The risk that the issuer of a security, or the counterparty to a
  contract, will default or otherwise become unable to honor a financial
  obligation. (All Fixed Income and Money Market Series)
o CURRENCY RISK: The risk related to investments denominated in foreign
  currencies. Foreign securities are usually denominated in foreign currency
  therefore changes in foreign currency exchange rates can affect the net asset
  value of the International Multi-Manager Series. (International Multi-Manager
  Series)
o DERIVATIVES RISK: Some of the WT Equity Series' investments may be referred to
  as "derivatives" because their value depends on, or derives from, the value of
  an underlying asset, reference rate or index. These investments include
  options, futures contracts and similar investments that may be used in hedging
  and related income strategies. The market value of derivative instruments and
  securities is sometimes more volatile than that of other investments, and each
  type of derivative may pose its own special risks. As a fundamental policy, no
  more than 15% of an Equity Series' total assets may at any time be committed
  or exposed to derivative strategies. (WT Equity Series)
o FOREIGN SECURITY RISK: The risk of losses due to political, regulatory,
  economic, social or other uncontrollable forces in a foreign country not
  normally associated with investing in the U.S. markets. (International
  Multi-Manager Series, the Large Cap Core Series, Short/Intermediate Bond
  Series, Intermediate Bond Series and all Money Market Series)
o GROWTH-ORIENTED INVESTING RISK: The risk that an investment in a
  growth-oriented portfolio, which invests in growth-oriented companies, will be
  more volatile than the rest of the U.S. market as a whole. (Large Cap Growth,
  WT Large Cap Growth, Large Cap Core and Small Cap Core Series)
o INTEREST RATE RISK: The risk of market losses attributable to changes in
  interest rates. With fixed-rate securities, a rise in interest rates typically
  causes a fall in values, while a fall in rates typically causes a rise in
  values. The yield earned by a Series will vary with changes in interest rates.
  (All Fixed Income and Money Market Series)
o LEVERAGE RISK: The risk associated with securities or practices (such as
  when-issued and forward commitment transactions) that multiply small market
  movements into larger changes in value. (All Fixed Income Series)

                                      A-9
<PAGE>


o LIQUIDITY RISK: The risk that certain securities may be difficult or
  impossible to sell at the time and the price that the seller would like. (All
  Fixed Income Series)
o MARKET RISK: The risk that the market value of a security may move up and
  down, sometimes rapidly and unpredictably. (All Series)
o OPPORTUNITY RISK: The risk of missing out on an investment opportunity because
  the assets necessary to take advantage of it are tied up in less advantageous
  investments. (All Equity and Fixed Income Series)
o PREPAYMENT RISK: The risk that a debt security may be paid off and proceeds
  invested earlier than anticipated. Depending on market conditions, the new
  investments may or may not carry the same interest rate. (All Fixed Income and
  Money Market Series)
o SMALL CAP RISK: Small cap companies may be more vulnerable than larger
  companies to adverse business or economic developments. Small cap companies
  may also have limited product lines, markets or financial resources, may be
  dependent on relatively small or inexperienced management groups and may
  operate in industries characterized by rapid technological obsolescence.
  Securities of such companies may be less liquid and more volatile than
  securities of larger companies and therefore may involve greater risk than
  investing in larger companies. (Small Cap Core Series)
o VALUATION RISK: The risk that a Series has valued certain of its securities at
  a higher price than it can sell them. (All Equity and Fixed Income Series)
o VALUE INVESTING RISK: The risk that a portfolio's investment in companies
  whose securities are believed to be undervalued, relative to their underlying
  profitability, do not appreciate in value as anticipated. (Large Cap Value,
  Mid Cap Value, Small Cap Value and Small Cap Core Series)
o YEAR 2000 COMPLIANCE RISK: Like other organizations around the world, the
  Series could be adversely affected if the computer systems used by their
  various service providers (or the market in general) do not properly operate
  after January 1, 2000. The Series are taking steps to address the Year 2000
  issue with respect to the computer systems that they rely on. There can be no
  assurance, however, that these steps will be sufficient to avoid a temporary
  service disruption or any adverse impact on the Series.

  Additionally, if a company in which a Series is invested is adversely affected
  by Year 2000 problems, it is likely that the price of that company's
  securities will also be adversely affected. A decrease in one or more of a
  Series' holdings may have a similar impact on the price of the Series' shares.
  Each Series' adviser or sub-adviser will rely on public filings and other
  statements made by companies about their Year 2000 readiness. Issuers in
  countries outside the U.S. present a greater Year 2000 readiness risk because
  they may not be required to make the same level of disclosure about Year 2000
  readiness as is required in the U.S. The adviser is not able to audit any
  company and its major suppliers to verify their Year 2000 readiness.

ITEM 6.  MANAGEMENT, ORGANIZATION, AND CAPITAL STRUCTURE.

(a)      MANAGEMENT.

The Board of Trustees for each Series supervises the management, activities and
affairs of the Series and has approved contracts with various financial
organizations to provide, among other services, the day-to-day management
required by a Series and its shareholders.

                                      A-14
<PAGE>

(a)(1-2) The Equity and Fixed Income Series value their assets based on current
market values when such values are available. These prices normally are supplied
by a pricing service. Fixed income securities maturing within 60 days of the
valuation date are valued at amortized cost. Any assets held by a Series that
are denominated in foreign currencies are valued daily in U.S. dollars at the
foreign currency exchange rates that are prevailing at the time that PFPC
determines the daily net asset value. To determine the value of those
securities, PFPC may use a pricing service that takes into account not only
developments related to specific securities, but also transactions in comparable
securities. Securities that do not have a readily available current market value
are valued in good faith under the direction of the Board of Trustees.

PFPC determines the NAV per share of each Equity and Fixed Income Series as of
the close of regular trading on the New York Stock Exchange (currently 4:00
p.m., Eastern time), on each Business Day (a day that the Exchange, the Transfer
Agent and the Philadelphia branch of the Federal Reserve Bank are open for
business). The NAV is calculated by adding the value of all securities and other
assets in a Series, deducting its liabilities and dividing the balance by the
number of outstanding shares in that Series.

MONEY MARKET SERIES

Each Money Market Series uses its best effort to maintain its $1 constant share
price and values its securities at cost. This involves valuing a security
initially at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of fluctuating interest rates on
the market value of the security. All cash, receivables and current payables are
carried at their face value. Other assets, if any, are valued at fair value as
determined in good faith by, or under the direction of, the Board of Trustees.

PFPC determines the NAV per share of each Series as of 12:00 p.m. Eastern time
for the Tax-Exempt Series and as of 2:00 p.m. Eastern Time for the U.S.
Government Series, the Prime Money Market Series, and the Premier Money Market
Series, on each Business Day (a day that the New York Stock Exchange, the
Transfer Agent and the Philadelphia branch of the Federal Reserve Bank are open
for business). The NAV is calculated by adding the value of all securities and
other assets in a Series, deducting its liabilities and dividing the balance by
the number of outstanding shares in that Series.

(a)(3) Shares will not be priced on those days when the Series' offices are
closed. As of the date of this prospectus, those days are:

     New Year's Day                  Memorial Day             Veterans Day
     Martin Luther King, Jr. Day     Independence Day         Thanksgiving Day
     President's Day                 Labor Day                Christmas Day
     Good Friday                     Columbus Day

(B)      PURCHASE OF FUND SHARES.

The Trust's shares have not been registered under the Securities Act of 1933,
which means that its shares may not be sold publicly. However, the Trust may
sell its shares through private placements pursuant to available exemptions from
registration under that Act.

Shares of the Trust may be sold only to: affiliates of WTC; subsidiaries of the
parent company of WTC; certain joint venture partners of affiliates of WTC; and
other institutional investors. Shares of the Series are sold at net asset value
without a sales charge. Shares are purchased at the net asset value next
determined after the Trust receives the order in proper form. All investments
are credited to the shareholder's account in the form of full and fractional
shares of the Series calculated to three decimal places. In the interest of
economy and convenience, certificates for shares will be issued only upon
written request.

                                      A-15
<PAGE>

The minimum initial investment in a Series is $1,000,000. There is no minimum
for subsequent investments.

The Trust distributes its own shares.

IN KIND PURCHASES
- -----------------

If accepted by the Trust, shares of each Series may be purchased in exchange for
securities which are eligible for acquisition by such Series as described in
this registration statement. Securities to be exchanged which are accepted by
the Trust and Trust shares to be issued therefore will be valued, as set forth
under "Pricing of Fund Shares" in Item 7(a), at the time of the next
determination of net asset value after such acceptance. All dividends, interest,
subscription, or other rights pertaining to such securities shall become the
property of the Series whose shares are being acquired and must be delivered to
the Trust by the investor upon receipt from the issuer.

The Trust will not accept securities in exchange for shares of a Series unless:
(1) current market quotations are readily available for such securities; (2) the
investor represents and agrees that all securities offered to be exchanged are
not subject to any restrictions upon their sale by the Series under the
Securities Act of 1933 or under the laws of the country in which the principal
market for such securities exists, or otherwise; (3) at the discretion of the
Series, the value of any such security (except U.S. Government securities) being
exchanged together with other securities of the same issuer owned by the Series
will not exceed 5% of the net assets of the Series immediately after the
transaction; and (4) the Series acquires the securities for investment and not
for resale. In addition, nearly all of the securities accepted in an exchange
must be, at the time of the exchange, eligible to be included in the Series
whose shares are issued. (See Item 4(b)) Investors interested in such exchanges
should contact the adviser.

(C)      REDEMPTION OF FUND SHARES.

As stated above in response to Item 7(b), "Purchase of Fund Shares," the Trust's
shares have not been registered under the Securities Act of 1933, which means
that its shares are restricted securities which may not be sold unless
registered or pursuant to an available exemption from that Act.

Redemptions are processed on any day on which the specific Series is open for
business and are effected at the Series' net asset value next determined after
the Series receives a redemption request in good form.

Redemption payments in cash will ordinarily be made within seven days after
receipt of the redemption request in good form. However, the right of redemption
may be suspended or the date of payment postponed in accordance with the 1940
Act. The amount received upon redemption may be more or less than the amount
paid for the shares depending upon the fluctuations in the market value of the
assets owned by the Series.

If the Board of Trustees determines that it would be detrimental to the best
interests of the remaining shareholders of any Series to make a particular
payment wholly or partly in cash, a Series may pay the redemption price in whole
or in part by a distribution of portfolio securities from the Series of the
shares being redeemed in lieu of cash in accordance with Rule 18f-1 under the
Investment Company Act of 1940. Investors may incur brokerage charges and other
transaction costs selling securities that were received in payment of
redemptions.

Although the redemption payments will ordinarily be made within seven days after
receipt, payment to investors redeeming shares which were purchased by check
will not be made until the Trust can verify that the payments for the purchase
have been, or will be, collected, which may take up to fifteen days or more.
Investors may avoid this delay by submitting a certified check along with the
purchase order.

(D)      DIVIDENDS AND DISTRIBUTIONS.

                                      A-16
<PAGE>

It is not expected that any Series will make cash or property distributions.
Rather, each investor can redeem part or all of its shares in a Series. As
explained below in (e), each investor will be required to report separately on
its own U.S. federal income tax return its distributive share (as determined in
accordance with the governing instruments of the Series) of a Series' income,
gains, losses, deductions and credits. Each investor will be required to report
its distributive share regardless of whether it has received a corresponding
distribution of cash or property from a Series.

(E)      TAX CONSEQUENCES.

Each Series of the Trust is intended to be taxable as a partnership for U.S.
federal income tax purposes.

The Series are series of a trust organized under Delaware law. The Series will
not be subject to any U.S. federal income tax. Instead, each investor will be
required to report separately on its own U.S. federal income tax return its
distributive share (as determined in accordance with the governing instruments
of the Series) of a Series' income, gains, losses, deductions and credits. Each
investor will be required to report its distributive share regardless of whether
it has received a corresponding distribution of cash or property from a Series.
An allocable share of a tax-exempt investor's income will be "unrelated business
taxable income" ("UBTI") only to the extent that a Series borrows money to
acquire property or invests in assets that produce UBTI or to the extent a
tax-exempt investor borrows money to make an investment in the Series. In
addition to U.S. federal income taxes, investors in the Series may also be
subject to state and local taxes on their distributive share of a Series'
income.

While the Series are not classified as "regulated investment companies" under
Subchapter M of the Code, the Series' assets, income and distributions will be
managed in such a way that an investor in the Series will be able to satisfy the
requirements of Subchapter M of the Code, assuming that the investor invested
all of its assets in a Series for such Series' entire fiscal year.

There are certain other tax issues that will be relevant to only certain of the
investors; for instance, investors that are segregated asset accounts and
investors who contribute assets rather than cash to the Series. It is intended
that contributions of assets will not be taxable provided certain requirements
are met. Such investors are advised to consult their own tax advisors as to the
tax consequences of an investment in the Series. Also, a Series may be required
to withhold taxes on distributions to foreign investors. Foreign investors
should contact their own tax advisors for more information with respect to any
applicable withholding on distributions from a Series.

Redemptions of shares in a Series may be taxable. In general, a redemption of
shares is taxable to the extent such cash or property received by the redeeming
investor exceeds such investor's tax basis in its shares.

It is not expected that any Series will make distributions of cash or property.
Instead, at the close of each fiscal year investors will be advised of their
allocable share of a Series' income, gains, losses deductions and credits for
U.S. federal income tax purposes.

If a Series of the Trust purchases shares in certain foreign investment
entities, called "passive foreign investment companies" ("PFIC"), the investors
in Series may be subject to U.S. federal income tax and a related interest
charge on a portion of any "excess distribution" or gain from the disposition of
such shares even if such income is distributed to investors in the Series and
whether or not such investors are subject to tax.

Certain Series of the Trust may be subject to foreign withholding taxes on
income from certain of their foreign securities.

                                      A-17
<PAGE>

The Series' taxable year-end will normally be June 30. Although, as described
above, the Series will not be subject to U.S. federal income tax, they will file
appropriate U.S. federal income tax returns.

MONEY MARKET SERIES


(b) INVESTMENT STRATEGIES AND RISKS. The following information supplements the
information concerning each Money Market Series' investment objective, policies
and limitations found in Item 4 of Part A.


The "Money Market Series" are the Prime Money Market, the Premier Money Market,
the U.S. Government and the Tax-Exempt Series. Each has adopted a fundamental
policy requiring it to maintain a constant net asset value of $1.00 per share,
although this may not be possible under certain circumstances. Each Series
values its portfolio securities on the basis of amortized cost (see "Purchase,
Redemption and Pricing of Shares") pursuant to Rule 2a-7 under the Investment
Company Act of 1940 (the "1940 Act"). As conditions of that Rule, the Board of
Trustees has established procedures reasonably designed to stabilize each
Series' price per share at $1.00 per share. Each Series maintains a
dollar-weighted average portfolio maturity of 90 days or less; purchases only
instruments with effective maturities of 397 days or less; and invests only in
securities which are of high quality as determined by major rating services or,
in the case of instruments which are not rated, of comparable quality as
determined by the investment adviser, Rodney Square Management Corporation,
under the direction of and subject to the review of the Board of Trustees.


BANK OBLIGATIONS. The Prime Money Market and the Premier Money Market Series may
invest in U.S. dollar-denominated obligations of major banks, including
certificates of deposit, time deposits and bankers' acceptances of major U.S.
and foreign banks and their branches located outside of the United States, of
U.S. branches of foreign banks, of foreign branches of foreign banks, of U.S.
agencies of foreign banks and of wholly owned banking subsidiaries of such
foreign banks located in the United States.


Obligations of foreign branches of U.S. banks and U.S. branches of wholly owned
subsidiaries of foreign banks may be general obligations of the parent bank, of
the issuing branch or subsidiary, or both, or may be limited by the terms of a
specific obligation or by governmental regulation. Because such obligations are
issued by foreign entities, they are subject to the risks of foreign investing.
A brief description of some typical types of bank obligations follows:

o BANKERS' ACCEPTANCES. The Prime Money Market, the Premier Money Market and the
  Tax-Exempt Series may invest in bankers' acceptances, which are credit
  instruments evidencing the obligation of a bank to pay a draft that has been
  drawn on it by a customer. These

<PAGE>


  instruments reflect the obligation of both the bank and the drawer to pay the
  face amount of the instrument upon maturity.

o CERTIFICATES OF DEPOSIT. The Prime Money Market, the Premier Money Market and
  the Tax-Exempt Series may invest in certificates evidencing the indebtedness
  of a commercial bank to repay funds deposited with it for a definite period of
  time (usually from 14 days to one year) at a stated or variable interest rate.
  Variable rate certificates of deposit provide that the interest rate will
  fluctuate on designated dates based on changes in a designated base rate (such
  as the composite rate for certificates of deposit established by the Federal
  Reserve Bank of New York).

o TIME DEPOSITS. The Prime Money Market and the Premier Money Market Series may
  invest in time deposits, which are bank deposits for fixed periods of time.


CERTIFICATES OF PARTICIPATION. The Tax-Exempt Series may invest in certificates
of participation, which give the investor an undivided interest in the municipal
obligation in the proportion that the investor's interest bears to the total
principal amount of the municipal obligation.


CORPORATE BONDS, NOTES AND COMMERCIAL PAPER. The Prime Money Market and the
Premier Money Market Series may invest in corporate bonds, notes and commercial
paper. These obligations generally represent indebtedness of the issuer and may
be subordinated to other outstanding indebtedness of the issuer. Commercial
paper consists of short-term unsecured promissory notes issued by corporations
in order to finance their current operations. The Series will only invest in
commercial paper rated, at the time of purchase, in the highest category by a
nationally recognized statistical rating organization ("NRSRO"), such as Moody's
or S&P or, if not rated, determined by the adviser to be of comparable quality.
The Series may invest in asset-backed commercial paper subject to Rule 2a-7
restrictions on investment in asset-backed securities, which include a
requirement that the security must have received a rating from a NRSRO.


FOREIGN SECURITIES. At the present time, portfolio securities of the Prime Money
Market and the Premier Money Market Series that are purchased outside the United
States are maintained in the custody of foreign branches of U.S. banks. To the
extent that the Series may maintain portfolio securities in the custody of
foreign subsidiaries of U.S. banks, and foreign banks or clearing agencies in
the future, those sub-custodian arrangements are subject to regulations under
the 1940 Act that govern custodial arrangements with entities incorporated or
organized in countries outside of the United States.


ILLIQUID SECURITIES. Each Money Market Series may not invest more than 10% of
the value of its net assets in securities that at the time of purchase have
legal or contractual restrictions on resale or are otherwise illiquid. Illiquid
securities are securities that cannot be disposed of within seven days at
approximately the value at which they are being carried on a Series' books.


The Board of Trustees has the ultimate responsibility for determining whether
specific securities are liquid or illiquid. The Board has delegated the function
of making day to day determinations of liquidity to the adviser, pursuant to
guidelines approved by the Board. The adviser will monitor the liquidity of
securities held by a Series and report periodically on such decisions to the
Board.


INVESTMENT COMPANY SECURITIES. The Money Market Series may invest in the
securities of other money market mutual funds, within the limits prescribed by
the 1940 Act. These limitations currently provide, in part, that a Series may
not purchase shares of an investment company if (a) such a purchase would cause
the Series to own in the aggregate more than 3% of the total outstanding voting
stock of the investment company or (b) such a purchase would cause the Series to
have more than 5% of its total assets invested in the investment company or (c)
more than 10% of the Series' total assets to be invested in the aggregate in all
investment companies. As a shareholder in an investment company, the Series
would bear its pro rata portion of the investment company's expenses, including
advisory fees, in addition to its own expenses.

                                      B-2
<PAGE>

The Series' investments of their assets in the corresponding Series pursuant to
the master/feeder structure are excepted from the above limitations.


MUNICIPAL SECURITIES. The Prime Money Market, the Premier Money Market and the
Tax-Exempt Series each may invest in debt obligations issued by states,
municipalities and public authorities ("Municipal Securities") to obtain funds
for various public purposes. Yields on Municipal Securities are the product of a
variety of factors, including the general conditions of the money market and of
the municipal bond and municipal note markets, the size of a particular
offering, the maturity of the obligation and the rating of the issue. Although
the interest on Municipal Securities may be exempt from federal income tax,
dividends paid by a Series to its shareholders may not be tax-exempt. A brief
description of some typical types of municipal securities follows:

o GENERAL OBLIGATION SECURITIES are backed by the taxing power of the issuing
  municipality and are considered the safest type of municipal bond.

o REVENUE OR SPECIAL OBLIGATION SECURITIES are backed by the revenues of a
  specific project or facility - tolls from a toll bridge, for example.

o BOND ANTICIPATION NOTES normally are issued to provide interim financing until
  long-term financing can be arranged. The long-term bonds then provide money
  for the repayment of the Notes.

o TAX ANTICIPATION NOTES finance working capital needs of municipalities and are
  issued in anticipation of various seasonal tax revenues, to be payable for
  these specific future taxes.

o REVENUE ANTICIPATION NOTES are issued in expectation of receipt of other kinds
  of revenue, such as federal revenues available under the Federal Revenue
  Sharing Program.

o INDUSTRIAL DEVELOPMENT BONDS ("IDBs") and Private Activity Bonds ("PABs") are
  specific types of revenue bonds issued on or behalf of public authorities to
  finance various privately operated facilities such as solid waste facilities
  and sewage plants. PABs generally are such bonds issued after April 15, 1986.
  These obligations are included within the term "municipal bonds" if the
  interest paid on them is exempt from federal income tax in the opinion of the
  bond issuer's counsel. IDBs and PABs are in most case revenue bonds and thus
  are not payable from the unrestricted revenues of the issuer. The credit
  quality of the IDBs and PABs is usually directly related to the credit
  standing of the user of the facilities being financed, or some form of credit
  enhancement such as a letter of credit.

o TAX-EXEMPT COMMERCIAL PAPER AND SHORT-TERM MUNICIPAL NOTES provide for
  short-term capital needs and usually have maturities of one year or less. They
  include tax anticipation notes, revenue anticipation notes and construction
  loan notes.

o CONSTRUCTION LOAN NOTES are sold to provide construction financing. After
  successful completion and acceptance, many projects receive permanent
  financing through the Federal Housing Administration by way of "Fannie Mae"
  (the Federal National Mortgage Association) or "Ginnie Mae" (the Government
  National Mortgage Association).

o PUT BONDS are municipal bonds which give the holder the right to sell the bond
  back to the issuer or a third party at a specified price and exercise date,
  which is typically well in advance of the bond's maturity date.


REPURCHASE AGREEMENTS. The Money Market Series may invest in repurchase
agreements. A repurchase agreement is a transaction in which a Series purchases
a security from a bank or recognized securities dealer and simultaneously
commits to resell that security to a bank or dealer at an agreed date and price

                                      B-3
<PAGE>


reflecting a market rate of interest, unrelated to the coupon rate or the
maturity of the purchased security. While it is not possible to eliminate all
risks from these transactions (particularly the possibility of a decline in the
market value of the underlying securities, as well as delays and costs to the
Series if the other party to the repurchase agreement becomes bankrupt), it is
the policy of a Series to limit repurchase transactions to primary dealers and
banks whose creditworthiness has been reviewed and found satisfactory by the
adviser. Repurchase agreements maturing in more than seven days are considered
illiquid for purposes of a Series' investment limitations.


SECURITIES LENDING. The Money Market Series may from time to time lend their
portfolio securities to brokers, dealers and financial institutions. Such loans
by a Series will in no event exceed one-third of that Series' total assets and
will be secured by collateral in the form of cash or securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities, which will
be maintained in an amount equal to the current market value of the loaned
securities at all times the loan is outstanding. Each Series will make loans of
securities only to firms deemed credit worthy by the adviser.


STANDBY COMMITMENTS. The Money Market Series may invest in standby commitments.
It is expected that stand-by commitments will generally be available without the
payment of any direct or indirect consideration. However, if necessary and
advisable, the Series may pay for standby commitments either separately in cash
or by paying a higher price for the obligations acquired subject to such a
commitment (thus reducing the yield to maturity otherwise available for the same
securities). Standby commitments purchased by the Series will be valued at zero
in determining net asset value and will not affect the valuation of the
obligations subject to the commitments. Any consideration paid for a standby
commitment will be accounted for as unrealized depreciation and will be
amortized over the period the commitment is held by a Series.


U.S. GOVERNMENT OBLIGATIONS. The Money Market Series may invest in debt
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities. Although all obligations of agencies and instrumentalities
are not direct obligations of the U.S. Treasury, payment of the interest and
principal on these obligations is generally backed directly or indirectly by the
U.S. Government. This support can range from securities supported by the full
faith and credit of the United States (for example, securities of the Government
National Mortgage Association), to securities that are supported solely or
primarily by the creditworthiness of the issuer, such as securities of the
Federal National Mortgage Association, Federal Home Loan Mortgage Corporation,
Tennessee Valley Authority, Federal Farm Credit Banks and the Federal Home Loan
Banks. In the case of obligations not backed by the full faith and credit of the
United States, a Series must look principally to the agency or instrumentality
issuing or guaranteeing the obligation for ultimate repayment and may not be
able to assert a claim against the United States itself in the event the agency
or instrumentality does not meet its commitments.


VARIABLE AND FLOATING RATE SECURITIES. The Money Market Series may invest in
variable and floating rate securities. The terms of variable and floating rate
instruments provide for the interest rate to be adjusted according to a formula
on certain pre-determined dates. Certain of these obligations also may carry a
demand feature that gives the holder the right to demand prepayment of the
principal amount of the security prior to maturity. An irrevocable letter of
credit or guarantee by a bank usually backs the demand feature. Series
investments in these securities must comply with conditions established by the
SEC under which they may be considered to have remaining maturities of 397 days
or less.


WHEN-ISSUED SECURITIES. The Money Market Series may buy when-issued securities
or sell securities on a delayed-delivery basis. This means that delivery and
payment for the securities normally will take place approximately 15 to 90 days
after the date of the transaction. The payment obligation and the interest rate
that will be received are each fixed at the time the buyer enters into the
commitment. During the period between purchase and settlement, the purchaser
makes no payment and no interest accrues to the purchaser. However, when a
security is sold on a delayed-delivery basis, the seller does not participate in
further gains or losses with respect to the security. If the other party to a
when-issued or delayed-delivery

                                      B-4
<PAGE>

transaction fails to transfer or pay for the securities, the Series could miss a
favorable price or yield opportunity or could suffer a loss.


A Series will make a commitment to purchase when-issued securities only with the
intention of actually acquiring the securities, but the Series may dispose of
the commitment before the settlement date if it is deemed advisable as a matter
of investment strategy. A Series may also sell the underlying securities before
they are delivered, which may result in gains or losses. A separate account for
each Series is established at the custodian bank, into which cash and/or liquid
securities equal to the amount of when-issued purchase commitments is deposited.
If the market value of the deposited securities declines additional cash or
securities will be placed in the account on a daily basis to cover the Series'
outstanding commitments.


When a Series purchases a security on a when-issued basis, the security is
recorded as an asset on the commitment date and is subject to changes in market
value generally, based upon changes in the level of interest rates. Thus, upon
delivery, the market value of the security may be higher or lower than its cost,
and this may increase or decrease the Series' net asset value. When payment for
a when-issued security is due, a Series will meet its obligations from
then-available cash flow, the sale of the securities held in the separate
account, the sale of other securities or from the sale of the when-issued
securities themselves. The sale of securities to meet a when-issued purchase
obligation carries with it the potential for the realization of capital gains or
losses.


(c) FUND POLICIES. Except as otherwise provided, the Money Market Series have
adopted the investment limitations set forth below. Limitations which are
designated as fundamental policies may not be changed without the affirmative
vote of the lessor of (i) 67% or more of the shares of a Series present at a
shareholders meeting if holders of more than 50% of the outstanding shares of
the Series are present in person or by proxy or (ii) more than 50% of the
outstanding shares of a Series. If any percentage restriction on investment or
utilization of assets is adhered to at the time an investment is made, a later
change in percentage resulting from a change in the market values of a Series'
assets or redemptions of shares will not be considered a violation of the
limitation.


Each Series will not as a matter of fundamental policy:


1. purchase the securities of any one issuer if, as a result, more than 5% of
the Series' total assets would be invested in the securities of such issuer, or
the Series would own or hold 10% or more of the outstanding voting securities of
that issuer, provided that (1) each Series may invest up to 25% of its total
assets without regard to these limitations; and (2) these limitations do not
apply to securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities;


2. purchase the securities of any issuer if, as a result, more than 25% of the
Series' total assets would be invested in the securities of one or more issuers
having their principal business activities in the same industry, provided, that
each of the Prime Money Market and Premier Money Market Series may invest more
than 25% of its total assets in the obligations of banks;


3. borrow money, except (1) from a bank for temporary or emergency purposes (not
for leveraging or investment) or (2) by engaging in reverse repurchase
agreements if the Series' borrowings do not exceed an amount equal to 33 1/3% of
the current value of its assets taken at market value, less liabilities other
than borrowings;


4. make loans to other persons, except by (1) purchasing debt securities in
accordance with its investment objective, policies and limitations; (2) entering
into repurchase agreements; or (3) engaging in securities loan transactions
limited to 33 1/3% of the value of the Series' total assets;


5. underwrite any issue of securities, except to the extent that the Series may
be considered to be

                                      B-5
<PAGE>

acting as underwriter in connection with the disposition of any portfolio
security;


6. purchase or sell real estate, provided that the Series may invest in
obligations secured by real estate or interests therein or obligations issued by
companies that invest in real estate or interests therein;


7. purchase or sell physical commodities or contracts, provided that currencies
and currency-related contracts will not be deemed physical commodities; or


8. issue senior securities, except as appropriate to evidence indebtedness that
the Series is permitted to incur, provided that the Series' use of options,
futures contracts and options thereon or currency-related contracts will not be
deemed to be senior securities for this purpose.


With respect to the exclusion from the investment limitation described in number
2 above, the Trust has been advised that it is the SEC staff's current position,
that the exclusion may be applied only to U.S. bank obligations; the Prime Money
Market and Premier Money Market Series, however, will consider both foreign and
U.S. bank obligations within this exclusion.


The following non-fundamental policies apply to each Money Market Series unless
otherwise indicated, and the Board of Trustees may change them without
shareholder approval.


Each Series will not:


1. make short sales of securities except short sales against the box;


2. purchase securities on margin except for the use of short-term credit
necessary for the clearance of purchases and sales of portfolio securities;


3. purchase portfolio securities if its outstanding borrowings exceed 5% of the
value of its total assets, and if at any time the Series' bank borrowings exceed
its fundamental borrowing limitations due to a decline in net assets, such
borrowings will be promptly (within 3 days) reduced to the extent necessary to
comply with such limitations;


4. make loans of portfolio securities unless such loans are fully collateralized
by cash, securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities, or any combination of cash and securities, marked to market
daily; or


5. with respect to the U.S. Government, Prime Money Market and Premier Money
Market Series only, purchase the securities of any one issuer if as a result
more than 5% of the Series' total assets would be invested in the securities of
such issuer, provided that this limitation does not apply to securities issued
or guaranteed by the U.S. Government, its agencies or instrumentalities.

BOND SERIES


 (b) INVESTMENT STRATEGIES AND RISKS. The following information supplements the
information concerning

                                      B-6
<PAGE>

each Bond Series' investment objective, policies and limitations found in Item 4
of Part A.

The "Bond Series" are the Short/Intermediate Bond, the Intermediate Bond and the
Municipal Bond Series. Wilmington Trust Company, the investment adviser for the
Bond Series, employs an investment process that is disciplined, systematic and
oriented toward a quantitative assessment and control of volatility. The Bond
Series' exposure to credit risk is moderated by limiting their investments to
securities that, at the time of purchase, are rated investment grade by a
nationally recognized statistical rating organization such as Moody's, S&P, or,
if unrated, are determined by the adviser to be of comparable quality. See
"Appendix B - Description of Ratings." Ratings, however, are not guarantees of
quality or of stable credit quality. Not even the highest rating constitutes
assurance that the security will not fluctuate in value or that a Series will
receive the anticipated yield on the security. WTC continuously monitors the
quality of the Series' holdings, and should the rating of a security be
downgraded or its quality be adversely affected, WTC will determine whether it
is in the best interest of the affected Series to retain or dispose of the
security.

The effect of interest rate fluctuations in the market on the principal value of
the Bond Series is moderated by limiting the average dollar-weighted duration of
their investments -- in the case of the Short/Intermediate Bond Series to a
range of 2 1/2 to 4 years, in the case of the Intermediate Bond Series to a
range of 4 to 7 years, and in the case of the Municipal Bond Series to a range
of 4 to 8 years. Investors may be more familiar with the term "average effective
maturity" (when, on average, the fixed income securities held by the Series will
mature), which is sometimes used to express the anticipated term of the Series'
investments. Generally, the stated maturity of a fixed income security is longer
than it's projected duration. Under normal market conditions, the average
effective maturity, in the case of the Short/Intermediate Bond Series, is
expected to fall within a range of approximately 3 to 5 years, in the case of
the Intermediate Bond Series, within a range of approximately 7 to 12 years, and
in the case of the Municipal Bond Series, within a range of approximately 5 to
10 years. In the event of unusual market conditions, the average dollar-weighted
duration of the Series may fall within a broader range. Under those
circumstances, the Short/Intermediate Bond and the Intermediate Bond Series may
invest in fixed income securities with an average dollar-weighted duration of 1
to 6 years and 2 to 10 years, respectively.

WTC's goal in managing the Short/Intermediate Bond and the Intermediate Bond
Series is to gain additional return by analyzing the market complexities and
individual security attributes which affect the returns of fixed income
securities. The Bond Series are intended to appeal to investors who want a
thoughtful exposure to the broad fixed income securities market and the high
current returns that characterize the short-term to intermediate-term sector of
that market.

Given the average duration of the holdings of the Bond Series and the current
interest rate environment, the Series should experience smaller price
fluctuations than those experienced by longer-term bond and municipal bond funds
and a higher yield than fixed-price money market and tax-exempt money market
funds. Of course, the Series will likely experience larger price fluctuations
than money market funds and a lower yield than longer-term bond and municipal
bond funds. Given the quality of the Series' holdings, which must be investment
grade (rated within the top four categories) or comparable to investment grade
securities at the time of purchase, the Series will accept lower yields in order
to avoid the credit concerns experienced by funds that invest in lower quality
fixed income securities. In addition, although the Municipal Bond Series expects
to invest substantially all of its net assets in municipal securities that
provide interest income that is exempt from federal income tax, it may invest up
to 20% of its net assets in other types of fixed income securities that provide
federally taxable income.

The composition of each Series' holdings varies depending upon WTC's analysis of
the fixed income markets and the municipal securities markets (for the Municipal
Bond Series), including analysis of the most attractive segments of the yield
curve, the relative value of the different market sectors, expected trends in
those markets and supply versus demand pressures. Securities purchased by the
Series may be purchased on the basis of their yield or potential capital
appreciation or both. By maintaining each Series' specified average duration,
WTC seeks to protect the Series' principal value by reducing fluctuations in
value relative to those that may be experienced by bond funds with longer
average durations. This strategy

                                      B-7
<PAGE>

may reduce the level of income attained by the Series. Of course, there is no
guarantee that principal value can be protected during periods of extreme
interest rate volatility.


WTC may make frequent changes in the Series' investments, particularly during
periods of rapidly fluctuating interest rates. These frequent changes would
involve transaction costs to the Series and could result in taxable capital
gains.


ASSET-BACKED SECURITIES. The Bond Series may purchase interests in pools of
obligations, such as credit card or automobile loan receivables, purchase
contracts and financing leases. Such securities are also known as "asset-backed
securities," and the holders thereof may be entitled to receive a fixed rate of
interest, a variable rate that is periodically reset to reflect the current
market rate or an auction rate that is periodically reset at auction.


Asset-backed securities are typically supported by some form of credit
enhancement, such as cash collateral, subordinated tranches, a letter of credit,
surety bond or limited guaranty. Credit enhancements do not provide protection
against changes in the market value of the security. If the credit enhancement
is exhausted or withdrawn, security holders may experience losses or delays in
payment if required payments of principal and interest are not made with respect
to the underlying obligations. Except in very limited circumstances, there is no
recourse against the vendors or lessors that originated the underlying
obligations.


Asset-backed securities are likely to involve unscheduled prepayments of
principal that may affect yield to maturity, result in losses, and may be
reinvested at higher or lower interest rates than the original investment. The
yield to maturity of asset-backed securities that represent residual interests
in payments of principal or interest in fixed income obligations is particularly
sensitive to prepayments.


The value of asset-backed securities may change because of changes in the
market's perception of the creditworthiness of the servicing agent for the pool
of underlying obligations, the originator of those obligations or the financial
institution providing credit enhancement.


BANK OBLIGATIONS. The Bond Series may invest in the same U.S. dollar-denominated
obligations of major banks as the Money Market Series. (See "Bank Obligations"
above)


CORPORATE BONDS, NOTES AND COMMERCIAL PAPER. The Bond Series may invest in
corporate bonds, notes and commercial paper. These obligations generally
represent indebtedness of the issuer and may be subordinated to other
outstanding indebtedness of the issuer. Commercial paper consists of short-term
unsecured promissory notes issued by corporations in order to finance their
current operations. The Series will only invest in commercial paper rated, at
the time of purchase, in the highest category by a nationally recognized
statistical rating organization, such as Moody's or S&P or, if not rated,
determined by WTC to be of comparable quality.


FIXED INCOME SECURITIES WITH BUY-BACK FEATURES. Fixed income securities with
buy-back features enable the Bond Series to recover principal upon tendering the
securities to the issuer or a third party. Letters of credit issued by domestic
or foreign banks often supports these buy-back features. In evaluating a foreign
bank's credit, WTC considers whether adequate public information about the bank
is available and whether the bank may be subject to unfavorable political or
economic developments, currency controls or other governmental restrictions that
could adversely affect the bank's ability to honor its commitment under the
letter of credit. The Municipal Bond Series will not acquire municipal
securities with buy-back features if, in the opinion of counsel, the existence
of a buy-back feature would alter the tax-exempt nature of interest payments on
the underlying securities and cause those payments to be taxable to that Series
and its shareholders.


Buy-back features include standby commitments, put bonds and demand features.

                                      B-8
<PAGE>

  o      STANDBY COMMITMENTS. The Bond Series may acquire standby commitments
         from broker-dealers, banks or other financial intermediaries to enhance
         the liquidity of portfolio securities. A standby commitment entitles a
         Series to same day settlement at amortized cost plus accrued interest,
         if any, at the time of exercise. The amount payable by the issuer of
         the standby commitment during the time that the commitment is
         exercisable generally approximates the market value of the securities
         underlying the commitment. Standby commitments are subject to the risk
         that the issuer of a commitment may not be in a position to pay for the
         securities at the time that the commitment is exercised.


         Ordinarily, a Series will not transfer a standby commitment to a third
         party, although the Series may sell securities subject to a standby
         commitment at any time. A Series may purchase standby commitments
         separate from or in conjunction with the purchase of the securities
         subject to the commitments. In the latter case, the Series may pay a
         higher price for the securities acquired in consideration for the
         commitment.

  o      PUT BONDS. A put bond (also referred to as a tender option or third
         party bond) is a bond created by coupling an intermediate or long-term
         fixed rate bond with an agreement giving the holder the option of
         tendering the bond to receive its par value. As consideration for
         providing this tender option, the sponsor of the bond (usually a bank,
         broker-dealer or other financial intermediary) receives periodic fees
         that equal the difference between the bond's fixed coupon rate and the
         rate (determined by a remarketing or similar agent) that would cause
         the bond, coupled with the tender option, to trade at par. By paying
         the tender offer fees, a Series in effect holds a demand obligation
         that bears interest at the prevailing short-term rate.


         In selecting put bonds for the Bond Series, WTC takes into
         consideration the creditworthiness of the issuers of the underlying
         bonds and the creditworthiness of the providers of the tender option
         features. A sponsor may withdraw the tender option feature if the
         issuer of the underlying bond defaults on interest or principal
         payments, the bond's rating is downgraded or, in the case of a
         municipal bond, the bond loses its tax-exempt status.

o DEMAND FEATURES. Many variable rate securities carry demand features that
  permit the holder to demand repayment of the principal amount of the
  underlying securities plus accrued interest, if any, upon a specified number
  of days' notice to the issuer or its agent. A demand feature may be
  exercisable at any time or at specified intervals. Variable rate securities
  with demand features are treated as having a maturity equal to the time
  remaining before the holder can next demand payment of principal. The issuer
  of a demand feature instrument may have a corresponding right to prepay the
  outstanding principal of the instrument plus accrued interest, if any, upon
  notice comparable to that required for the holder to demand payment.


GUARANTEED INVESTMENT CONTRACTS. A guaranteed investment contract ("GIC") is a
general obligation of an insurance company. A GIC is generally structured as a
deferred annuity under which the purchaser agrees to pay a given amount of money
to an insurer (either in a lump sum or in installments) and the insurer promises
to pay interest at a guaranteed rate (either fixed or variable) for the life of
the contract. Some GICs provide that the insurer may periodically pay
discretionary excess interest over and above the guaranteed rate. At the GIC's
maturity, the purchaser generally is given the option of receiving payment or an
annuity. Certain GICs may have features that permit redemption by the issuer at
a discount from par value.


Generally, GICs are not assignable or transferable without the permission of the
issuer. As a result, the acquisition of GICs is subject to the limitations
applicable to each Series' acquisition of illiquid and restricted securities.
The holder of a GIC is dependent on the creditworthiness of the issuer as to
whether the issuer is able to meet its obligations. No Series intends to invest
more than 5% of its net assets in GICs.

                                      B-9
<PAGE>

ILLIQUID SECURITIES. The Bond Series may not invest more than 15% of the value
of their net assets in securities that at the time of purchase have legal or
contractual restrictions on resale or are otherwise illiquid.


MONEY MARKET FUNDS. The Bond Series may invest in the securities of money market
mutual funds, within the limits prescribed by the 1940 Act, as previously
described for the Money Market Series under "Investment Company Securities."


MORTGAGE-BACKED SECURITIES. Mortgage-backed securities are securities
representing interests in a pool of mortgages secured by real property.


Government National Mortgage Association ("GNMA") mortgage-backed securities are
securities representing interests in pools of mortgage loans to residential home
buyers made by lenders such as mortgage bankers, commercial banks and savings
associations and are either guaranteed by the Federal Housing Administration or
insured by the Veterans Administration. Timely payment of interest and principal
on each mortgage loan is backed by the full faith and credit of the U.S.
Government.


The Federal National Mortgage Association ("FNMA") and Federal Home Loan
Mortgage Corporation ("FHLMC") both issue mortgage-backed securities that are
similar to GNMA securities in that they represent interests in pools of mortgage
loans. FNMA guarantees timely payment of interest and principal on its
certificates and FHLMC guarantees timely payment of interest and ultimate
payment of principal. FHLMC also has a program under which it guarantees timely
payment of scheduled principal as well as interest. FNMA and FHLMC guarantees
are backed only by those agencies and not by the full faith and credit of the
U.S. Government.


In the case of mortgage-backed securities that are not backed by the U.S.
Government or one of its agencies, a loss could be incurred if the collateral
backing these securities is insufficient. This may occur even though the
collateral is U.S. Government-backed.


Most mortgage-backed securities pass monthly payment of principal and interest
through to the holder after deduction of a servicing fee. However, other payment
arrangements are possible. Payments may be made to the holder on a different
schedule than that on which payments are received from the borrower, including,
but not limited to, weekly, bi-weekly and semiannually. The monthly principal
and interest payments also are not always passed through to the holder on a PRO
RATA basis. In the case of collateralized mortgage obligations ("CMOs"), the
pool is divided into two or more tranches and special rules for the disbursement
of principal and interest payments are established.


CMO residuals are derivative securities that generally represent interests in
any excess cash flow remaining after making required payments of principal and
interest to the holders of the CMOs described above. Yield to maturity on CMO
residuals is extremely sensitive to prepayments. In addition, if a series of a
CMO includes a class that bears interest at an adjustable rate, the yield to
maturity on the related CMO residual also will be extremely sensitive to the
level of the index upon which interest rate adjustments are based.


Stripped mortgage-backed securities ("SMBS") are derivative multi-class mortgage
securities and may be issued by agencies or instrumentalities of the U.S.
Government or by private mortgage lenders. SMBS usually are structured with two
classes that receive different proportions of the interest and/or principal
distributions on a pool of mortgage assets. A common type of SMBS will have one
class of holders receiving all interest payments -- "interest only" or "IO" --
and another class of holders receiving the principal repayments -- "principal
only" or "PO." The yield to maturity of IO and PO classes is extremely sensitive
to prepayments on the underlying mortgage assets.


MUNICIPAL SECURITIES. Municipal securities are debt obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia and their sub-divisions, agencies and

                                      B-10
<PAGE>

instrumentalities, the interest on which is, in the opinion of bond counsel,
exempt from federal income tax. These debt obligations are issued to obtain
funds for various public purposes, such as the construction of public
facilities, the payment of general operating expenses or the refunding of
outstanding debts. They may also be issued to finance various privately owned or
operated activities. The three general categories of municipal securities are
general obligation, revenue or special obligation and private activity municipal
securities. A brief description of typical municipal securities follows:

  o           GENERAL OBLIGATION SECURITIES are backed by the taxing power of
              the issuing municipality and are considered the safest type of
              municipal bond. The proceeds from general obligation securities
              are used to fund a wide range of public projects, including the
              construction or improvement of schools, highways and roads, and
              water and sewer systems.

  o           REVENUE OR SPECIAL OBLIGATION SECURITIES are backed by the
              revenues of a specific project or facility - tolls from a toll
              bridge, for example. The proceeds from revenue or special
              obligation securities are used to fund a wide variety of capital
              projects, including electric, gas, water and sewer systems;
              highways, bridges and tunnels; port and airport facilities;
              colleges and universities; and hospitals. Many municipal issuers
              also establish a debt service reserve fund from which principal
              and interest payments are made. Further security may be available
              in the form of the state's ability, without obligation, to make up
              deficits in the reserve fund.

  o           MUNICIPAL LEASE OBLIGATIONS may take the form of a lease, an
              installment purchase or a conditional sale contract issued by
              state and local governments and authorities to acquire land,
              equipment and facilities. Usually, the Series will purchase a
              participation interest in a municipal lease obligation from a bank
              or other financial intermediary. The participation interest gives
              the holder a pro rata, undivided interest in the total amount of
              the obligation.


              Municipal leases frequently have risks distinct from those
              associated with general obligation or revenue bonds. The interest
              income from the lease obligation may become taxable if the lease
              is assigned. Also, to free the municipal issuer from
              constitutional or statutory debt issuance limitations, many leases
              and contracts include non-appropriation clauses providing that the
              municipality has no obligation to make future payments under the
              lease or contract unless money is appropriated for that purpose by
              the municipality on a yearly or other periodic basis. Finally, the
              lease may be illiquid.

  o           RESOURCE RECOVERY BONDS are affected by a number of factors, which
              may affect the value and credit quality of these revenue or
              special obligations. These factors include the viability of the
              project being financed, environmental protection regulations and
              project operator tax incentives.

  o           PRIVATE ACTIVITY SECURITIES are specific types of revenue bonds
              issued on behalf of public authorities to finance various
              privately operated facilities such as educational, hospital or
              housing facilities, local facilities for water supply, gas,
              electricity, sewage or solid waste disposal, and industrial or
              commercial facilities. The payment of principal and interest on
              these obligations generally depends upon the credit of the private
              owner/user of the facilities financed and, in certain instances,
              the pledge of real and personal property by the private
              owner/user. The interest income from certain types of private
              activity securities may be considered a tax preference item for
              purposes of the federal alternative minimum tax ("Tax Preference
              Item").


Short-term municipal securities in which the Series may invest include Tax
Anticipation, Revenue Anticipation, Bond Anticipation and Construction Loan
Notes, which were previously described for the Money Market Series (See
"Municipal Securities" above).

                                      B-11
<PAGE>

OPTIONS, FUTURES AND FORWARD CURRENCY CONTRACT STRATEGIES. Although the
Municipal Bond Series has no current intention of so doing, each of the Bond
Series may use options and futures contracts. The Short/Intermediate Bond and
the Intermediate Bond Series may use forward currency contracts.


PARTICIPATION INTERESTS. The Bond Series may invest in participation interests
in fixed income securities. A participation interest provides the certificate
holder with a specified interest in an issue of fixed income securities.


Some participation interests give the holders differing interests in the
underlying securities, depending upon the type or class of certificate
purchased. For example, coupon strip certificates give the holder the right to
receive a specific portion of interest payments on the underlying securities;
principal strip certificates give the holder the right to receive principal
payments and the portion of interest not payable to coupon strip certificate
holders. Holders of certificates of participation in interest payments may be
entitled to receive a fixed rate of interest, a variable rate that is
periodically reset to reflect the current market rate or an auction rate that is
periodically reset at auction. Asset-backed residuals represent interests in any
excess cash flow remaining after required payments of principal and interest
have been made.


More complex participation interests involve special risk considerations. Since
these instruments have only recently been developed, there can be no assurance
that any market will develop or be maintained for the instruments. Generally,
the fixed income securities that are deposited in trust for the holders of these
interests are the sole source of payments on the interests; holders cannot look
to the sponsor or trustee of the trust or to the issuers of the securities held
in trust or to any of their affiliates for payment.


Participation interests purchased at a discount may experience price volatility.
Certain types of interests are sensitive to fluctuations in market interest
rates and to prepayments on the underlying securities. A rapid rate of
prepayment can result in the failure to recover the holder's initial investment.


The extent to which the yield to maturity of a participation interest is
sensitive to prepayments depends, in part, upon whether the interest was
purchased at a discount or premium, and if so, the size of that discount or
premium. Generally, if a participation interest is purchased at a premium and
principal distributions occur at a rate faster than that anticipated at the time
of purchase, the holder's actual yield to maturity will be lower than that
assumed at the time of purchase. Conversely, if a participation interest is
purchased at a discount and principal distributions occur at a rate faster than
that assumed at the time of purchase, the investor's actual yield to maturity
will be higher than that assumed at the time of purchase.


Participation interests in pools of fixed income securities backed by certain
types of debt obligations involve special risk considerations. The issuers of
securities backed by automobile and truck receivables typically file financing
statements evidencing security interests in the receivables, and the servicers
of those obligations take and retain custody of the obligations. If the
servicers, in contravention of their duty to the holders of the securities
backed by the receivables, were to sell the obligations, the third party
purchasers could acquire an interest superior to the interest of the security
holders. Also, most states require that a security interest in a vehicle must be
noted on the certificate of title and the certificate of title may not be
amended to reflect the assignment of the lender's security interest. Therefore,
the recovery of the collateral in some cases may not be available to support
payments on the securities. Securities backed by credit card receivables are
generally unsecured, and both federal and state consumer protection laws may
allow set-offs against certain amounts owed.


The Municipal Bond Series will only invest in participation interests in
municipal securities, municipal leases or in pools of securities backed by
municipal assets if, in the opinion of counsel, any interest income on the
participation interest will be exempt from federal income tax to the same extent
as the interest on the underlying securities.

                                      B-12
<PAGE>

REPURCHASE AGREEMENTS. The Bond Series may invest in repurchase agreements,
which were previously described for the Money Market Portfolios (See "Repurchase
Agreements" above).


SECURITIES LENDING. The Bond Series may lend securities pursuant to agreements,
which require that the loans be continuously secured by collateral equal to 100%
of the market value of the loaned securities. Such collateral consists of cash,
securities of the U.S. Government or its agencies, or any combination of cash
and such securities. Such loans will not be made if, as a result, the aggregate
amount of all outstanding securities loans for a Series exceed one-third of the
value of the Series' total assets taken at fair market value. A Series will
continue to receive interest on the securities lent while simultaneously earning
interest on the investment of the cash collateral in U.S. Government securities.
However, a Series will normally pay lending fees to such broker-dealers and
related expenses from the interest earned on invested collateral. There may be
risks of delay in receiving additional collateral or risks of delay in recovery
of the securities and even loss of rights in the collateral should the borrower
of the securities fail financially. However, loans are made only to borrowers
deemed by the adviser to be of good standing and when, in the judgment of the
adviser, the consideration that can be earned currently from such securities
loans justifies the attendant risk. Either party upon reasonable notice to the
other party may terminate any loan. The Municipal Bond Series has no current
intention of lending its portfolio securities and would do so only under unusual
market conditions since the interest income that a Series receives from lending
its securities is taxable.


U.S. GOVERNMENT OBLIGATIONS. The Bond Series may invest in the same debt
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities as the Money Market Series. (See "U.S. Government
Obligations").


VARIABLE AND FLOATING RATE SECURITIES. The Bond Series may invest in variable
and floating rate securities. The terms of variable and floating rate
instruments provide for the interest rate to be adjusted according to a formula
on certain pre-determined dates. Certain of these obligations also may carry a
demand feature that gives the holder the right to demand prepayment of the
principal amount of the security prior to maturity. An irrevocable letter of
credit or guarantee by a bank usually backs the demand feature. Series
investments in these securities must comply with conditions established by the
SEC under which they may be considered to have remaining maturities of 397 days
or less.


Each of the Bond Series may also purchase inverse floaters that are floating
rate instruments whose interest rates bear an inverse relationship to the
interest rate on another security or the value of an index. Changes in the
interest rate on the other security or index inversely affect the interest rate
paid on the inverse floater, with the result that the inverse floater's price is
considerably more volatile than that of a fixed rate security. For example, an
issuer may decide to issue two variable rate instruments instead of a single
long-term, fixed rate bond. The interest rate on one instrument reflects
short-term interest rates, while the interest rate on the other instrument (the
inverse floater) reflects the approximate rate the issuer would have paid on a
fixed rate bond multiplied by two minus the interest rate paid on the short-term
instrument. Depending on market availability, the two variable rate instruments
may be combined to form a fixed rate bond. The market for inverse floaters is
relatively new.


WHEN-ISSUED SECURITIES. The Bond Series may buy when-issued securities or sell
securities on a delayed-delivery basis. This means that delivery and payment for
the securities normally will take place approximately 15 to 90 days after the
date of the transaction. The payment obligation and the interest rate that will
be received are each fixed at the time the buyer enters into the commitment.
During the period between purchase and settlement, the purchaser makes no
payment and no interest accrues to the purchaser. However, when a security is
sold on a delayed-delivery basis, the seller does not participate in further
gains or losses with respect to the security. If the other party to a
when-issued or delayed-delivery transaction fails to transfer or pay for the
securities, the Series could miss a favorable price or yield opportunity or
could suffer a loss.

                                      B-13
<PAGE>

A Series will make a commitment to purchase when-issued securities only with the
intention of actually acquiring the securities, but the Series may dispose of
the commitment before the settlement date if it is deemed advisable as a matter
of investment strategy. A Series may also sell the underlying securities before
they are delivered, which may result in gains or losses. A separate account for
each Series is established at the custodian bank, into which cash and/or liquid
securities equal to the amount of when-issued purchase commitments is deposited.
If the market value of the deposited securities declines additional cash or
securities will be placed in the account on a daily basis to cover the Series'
outstanding commitments.


When a Series purchases a security on a when-issued basis, the security is
recorded as an asset on the commitment date and is subject to changes in market
value generally, based upon changes in the level of interest rates. Thus, upon
delivery, the market value of the security may be higher or lower than its cost,
and this may increase or decrease the Series' net asset value. When payment for
a when-issued security is due, a Series will meet its obligations from
then-available cash flow, the sale of the securities held in the separate
account, the sale of other securities or from the sale of the when-issued
securities themselves. The sale of securities to meet a when-issued purchase
obligation carries with it the potential for the realization of capital gains or
losses.


The Municipal Bond Series may purchase securities on a when-issued basis in
connection with the refinancing of an issuer's outstanding indebtedness
("refunding contracts"). These contracts require the issuer to sell and the
Series to buy municipal obligations at a stated price and yield on a settlement
date that may be several months or several years in the future. The offering
proceeds are then used to refinance existing municipal obligations. Although the
Municipal Bond Series may sell its rights under a refunding contract, the
secondary market for these contracts may be less liquid than the secondary
market for other types of municipal securities. The Series generally will not be
obligated to pay the full purchase price if it fails to perform under a
refunding contract. Instead, refunding contracts usually provide for payment of
liquidated damages to the issuer (currently 15-20% of the purchase price). The
Series may secure its obligation under a refunding contract by depositing
collateral or a letter of credit equal to the liquidated damages provision of
the refunding contract. When required by Securities and Exchange Commission
("SEC") guidelines, the Series will place liquid assets in a segregated
custodial account equal in amount to its obligations under outstanding refunding
contracts.


ZERO COUPON BONDS. The Bond Series may invest in zero coupon bonds of
governmental or private issuers that generally pay no interest to their holders
prior to maturity. Since zero coupon bonds do not make regular interest
payments, they allow an issuer to avoid the need to generate cash to meet
current interest payments and may involve greater credit risks than bonds paying
interest currently. Tax laws requiring the distribution of accrued discount on
the bonds, even though no cash equivalent thereto has been paid, may cause a
Series to liquidate investments in order to make the required distributions.


RISK FACTORS APPLICABLE TO THE MUNICIPAL BOND SERIES:


HEALTH CARE SECTOR. The health care industry is subject to regulatory action by
a number of private and governmental agencies, including federal, state and
local governmental agencies. A major source of revenues for the industry is
payments from the Medicare and Medicaid programs. As a result, the industry is
sensitive to legislative changes and reductions in governmental spending for
those programs. Numerous other factors may affect the industry, such as general
and local economic conditions; demand for services; expenses (including
malpractice insurance premiums) and competition among health care providers. In
the future, the following may adversely affect the industry: adoption of
legislation proposing a national health insurance program; medical and
technological advances which alter the demand for health services or the way in
which such services are provided; and efforts by employers, insurers and
governmental agencies to reduce the costs of health insurance and health care
services.


Health care facilities include life care facilities, nursing homes and
hospitals. The Municipal Bond Series may invest in bonds to finance these
facilities which are typically secured by the revenues from the

                                      B-14
<PAGE>

facilities and not by state or local government tax payments. Moreover, in the
case of life care facilities, since a portion of housing, medical care and other
services may be financed by an initial deposit, there may be a risk of default
in the payment of principal or interest on a bond issue if the facility does not
maintain adequate financial reserves for debt service.


HOUSING SECTOR. The Municipal Bond Series may invest in housing revenue bonds
which typically are issued by state, county and local housing authorities and
are secured only by the revenues of mortgages originated by those authorities
using the proceeds of the bond issues. Factors that may affect the financing of
multi-family housing projects include acceptable completion of construction,
proper management, occupancy and rent levels, economic conditions and changes in
regulatory requirements.


Since the demand for mortgages from the proceeds of a bond issue cannot be
precisely predicted, the proceeds may be in excess of demand, which would result
in early retirement of the bonds by the issuer. Since the cash flow from
mortgages cannot be precisely predicted, differences in the actual cash flow
from the assumed cash flow could have an adverse impact upon the issuer's
ability to make scheduled payments of principal and interest or could result in
early retirement of the bonds.


Scheduled principal and interest payments are often made from reserve or sinking
funds. These reserves are funded from the bond proceeds, assuming certain rates
of return on investment of the reserve funds. If the assumed rates of return are
not realized because of changes in interest rate levels or for other reasons,
the actual cash flow for scheduled payments of principal and interest on the
bonds may be inadequate.


ELECTRIC UTILITIES SECTOR. The electric utilities industry has experienced, and
may experience in the future: problems in financing large construction programs
in an inflationary period; cost increases and delays caused by environmental
considerations (particularly with respect to nuclear facilities); difficulties
in obtaining fuel at reasonable prices; the effects of conservation on the
demand for energy; increased competition from alternative energy sources; and
the effects of rapidly changing licensing and safety requirements.


PROPOSED LEGISLATION. From time to time, proposals have been introduced before
Congress for the purpose of restricting or eliminating the federal income tax
exemption for interest on debt obligations issued by states and their political
subdivisions. For example, federal tax law now limits the types and amounts of
tax-exempt bonds issuable for industrial development and other types of private
activities. These limitations may affect the future supply and yields of private
activity securities. Further proposals affecting the value of tax-exempt
securities may be introduced in the future. In addition, proposals have been
made, such as that involving the "flat tax," that could reduce or eliminate the
value of that exemption. If the availability of municipal securities for
investment or the value of the Municipal Bond Series' holdings could be
materially affected by such changes in the law, the Trustees would reevaluate
the Series' investment objective and policies or consider the Series'
dissolution.


(c) FUND POLICIES. Except as otherwise provided, the Bond Series have adopted
the investment limitations set forth below. Limitations which are designated as
fundamental policies may not be changed without the affirmative vote of the
lessor of (i) 67% or more of the shares of a Series present at a shareholders
meeting if holders of more than 50% of the outstanding shares of the Series are
present in person or by proxy or (ii) more than 50% of the outstanding shares of
a Series. If any percentage restriction on investment or utilization of assets
is adhered to at the time an investment is made, a later change in percentage
resulting from a change in the market values of a Series' assets or redemptions
of shares will not be considered a violation of the limitation.


Each Series will not as a matter of fundamental policy:


1. purchase the securities of any one issuer if, as a result, more than 5% of
the Series' total assets would be invested in the securities of such issuer, or
the Series would own or hold 10% or more of the outstanding voting securities of
that issuer, provided that (1) each Series may invest up to 25% of its total

                                      B-15
<PAGE>


assets without regard to these limitations; and (2) these limitations do not
apply to securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities;


2. purchase the securities of any issuer if, as a result, more than 25% of the
Series' total assets would be invested in the securities of one or more issuers
having their principal business activities in the same industry, provided that
this limitation does not apply to securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities (including repurchase agreements
fully collateralized by U.S. Government obligations) or to tax-exempt municipal
securities;


3. borrow money, provided that the Series may borrow money from banks for
temporary or emergency purposes (not for leveraging or investment) or by
engaging in reverse repurchase agreements if the Series' borrowings do not
exceed an amount equal to 33 1/3% of the current value of its assets taken at
market value, less liabilities other than borrowings;


4. make loans to other persons, except by (1) purchasing debt securities in
accordance with its investment objective, policies and limitations; (2) entering
into repurchase agreements; or (3) engaging in securities loan transactions
limited to 33 1/3% of the value of the Series' total assets;


5. underwrite any issue of securities, except to the extent that the Series may
be considered to be acting as underwriter in connection with the disposition of
any portfolio security;


6. purchase or sell real estate or real estate limited partnership interests,
provided that the Series may invest in obligations secured by real estate or
interests therein or obligations issued by companies that invest in real estate
or interests therein, including real estate investment trusts;


7. purchase or sell physical commodities or commodities contracts except
financial and foreign currency futures contracts and options thereon, options on
foreign currencies and forward currency contracts; or


8. issue senior securities, except as appropriate to evidence indebtedness that
the Series is permitted to incur, provided that futures, options and forward
currency transactions will not be deemed to be senior securities for purposes of
this limitation.


The following non-fundamental policies apply to each Series and may be changed
by the Board of Trustees without shareholder approval. Each Series will not:


1. pledge, mortgage or hypothecate its assets, except the Series may pledge
securities having a market value at the time of the pledge not exceeding 33 1/3%
of the value of its total assets to secure borrowings, and the Series may
deposit initial and variation margin in connection with transactions in futures
contracts and options on futures contracts;


2. make short sales of securities except short sales against the box;


3. purchase securities on margin except for the use of short-term credit
necessary for the clearance of purchases and sales of portfolio securities,
provided that the Series may make initial and variation margin deposits in
connection with permitted transactions in options or futures;


4. purchase portfolio securities if its outstanding borrowings exceed 5% of the
value of its total assets;


5. when engaging in options, futures and forward currency contract strategies, a
Series will either: (1) set aside cash or liquid securities in a segregated
account with the Fund's custodian in the prescribed amount; or (2) hold
securities or other options or futures contracts whose values are expected to
offset ("cover") its obligations thereunder. Securities, currencies or other
options or futures contracts used for

                                      B-16
<PAGE>

cover cannot be sold or closed out while the strategy is outstanding, unless
they are replaced with similar assets;


6. purchase or sell non-hedging futures contracts or related options if
aggregate initial margin and premiums required to establish such positions would
exceed 5% of the Series' total assets. For purposes of this limitation,
unrealized profits and unrealized losses on any open contracts are taken into
account, and the in-the-money amount of an option that is in-the-money at the
time of purchase is excluded; or


7. write put or call options having aggregate exercise prices greater than 25%
of the Series' net assets, except with respect to options attached to or
acquired with or traded together with their underlying securities and securities
that incorporate features similar to options.

(D)       TEMPORARY DEFENSIVE POSITION.

EQUITY SERIES


 (b) INVESTMENT STRATEGIES AND RISKS. The following information supplements the
information concerning each Equity Series' investment objective, policies and
limitations found in Item 4 of Part A.


The "Equity Series" are the Large Cap Growth, the WT Large Cap Growth, the Large
Cap Core, the Small Cap Core, the International Multi-Manager, the Large Cap
Value, the Mid Cap Value and the Small Cap Value Series.


AMERICAN DEPOSITARY RECEIPTS (ADRS) AND EUROPEAN DEPOSITARY RECEIPTS (EDRS). The
International Multi-Manager and Large Cap Core Series each may invest in ADRs
and EDRs. ADRs and EDRs are securities, typically issued by a U.S. financial
institution or a non-U.S. financial institution in the case of an EDR (a
"depositary"). The institution has ownership interests in a security, or a pool
of securities, issued by a foreign issuer and deposited with the depositary.
ADRs and EDRs may be available through "sponsored" or "unsponsored" facilities.
A sponsored facility is established jointly by the issuer of the security
underlying the receipt and a depositary. An unsponsored facility may be
established by a depositary without participation by the issuer of the
underlying security. Holders of unsponsored depositary receipts generally bear
all the costs of the unsponsored facility. The depositary of an unsponsored
facility frequently is under no obligation to distribute shareholder
communications received from the issuer of the deposited security or to pass
through, to the holders of the receipts, voting rights with respect to the
deposited securities.


CASH MANAGEMENT. The Small Cap Core and the International Multi-Manager Series
each may invest no more than 15% of its total assets in cash and cash
equivalents including high-quality money market instruments and money market
funds in order to manage cash flow in the Series. The other Equity Series

                                      B-17
<PAGE>

are not subject to specific percentage limitations on such investments. Certain
of these instruments are described below.

o MONEY MARKET FUNDS. The Equity Series may invest in the securities of other
  money market mutual funds, within the limits prescribed by the 1940 Act. The
  International Multi-Manager Series may invest in securities of open-end and
  closed-end investment companies that invest primarily in the equity securities
  of issuers in countries where it is impossible or impractical to invest
  directly. Such investments will be subject to the limits described above.

o U.S. GOVERNMENT OBLIGATIONS. The Equity Series may invest in the same debt
  securities issued or guaranteed by the U.S. Government, its agencies or
  instrumentalities as the Money Market Series. (See "U.S. Government
  Obligations" above)

o COMMERCIAL PAPER. The Equity Series may invest in commercial paper. Commercial
  paper consists of short-term (up to 270 days) unsecured promissory notes
  issued by corporations in order to finance their current operations. The
  Series may invest only in commercial paper rated A-1 or higher by S&P or
  Moody's or if not rated, determined by the adviser or sub-adviser to be of
  comparable quality.

o BANK OBLIGATIONS. The Equity Series may invest in the same obligations of U.S.
  banks as the Money Market Funds. (See "Bank Obligations" above)


CONVERTIBLE SECURITIES. Convertible securities have characteristics similar to
both fixed income and equity securities. Because of the conversion feature, the
market value of convertible securities tends to move together with the market
value of the underlying stock. As a result, a Series' selection of convertible
securities is based, to a great extent, on the potential for capital
appreciation that may exist in the underlying stock. The value of convertible
securities is also affected by prevailing interest rates, the credit quality of
the issuers and any call provisions.


The Equity Series may invest in convertible securities that are rated, at the
time of purchase, in the three highest rating categories by a nationally
recognized statistical rating organization ("NRSRO") such as Moody's or S&P, or
if unrated, are determined by the adviser or a sub-adviser, as applicable, to be
of comparable quality. In addition, the International Multi-Manager Series may
invest in non-convertible debt securities issued by foreign governments,
international agencies, and private foreign issuers that, at the time of
purchase, are rated A or better by a NRSRO, or, if not rated, are judged by the
adviser or one or more of the sub-advisers to be of comparable quality. Ratings
represent the rating agency's opinion regarding the quality of the security and
are not a guarantee of quality. Should the rating of a security be downgraded
subsequent to a Series' purchase of the security, the adviser or a sub-adviser,
as applicable, will determine whether it is in the best interest of the Series
to retain the security.


DEBT SECURITIES. Debt securities represent money borrowed that obligates the
issuer (e.g., a corporation, municipality, government, government agency) to
repay the borrowed amount at maturity (when the obligation is due and payable)
and usually to pay the holder interest at specific times.


HEDGING STRATEGIES. The Equity Series may engage in certain hedging strategies
that involve options, futures and, in the case of the International
Multi-Manager Series, forward currency exchange contracts.


ILLIQUID SECURITIES. Each of the Large Cap Value, Mid Cap Value and Small Cap
Value Series may invest no more than 10% of their net assets in securities that
at the time of purchase have legal or contractual restrictions on resale or are
otherwise illiquid. Each of the Large Cap Growth, WT Large Cap Growth, Large Cap
Core, Small Cap Core and International Multi-Manager Series may invest no more
than 15% of their net assets in securities that at the time of purchase have
legal or contractual restrictions on resale or are otherwise illiquid. If the
limitations on illiquid securities are exceeded, other than by a change in

                                      B-18
<PAGE>

market values, the condition will be reported by the Series' investment adviser
to the Board of Trustees.


OPTIONS ON SECURITIES AND SECURITIES INDEXES. The Large Cap Growth, WT Large Cap
Growth, Large Cap Value and Small Cap Core Series each may purchase call options
on securities that WTC intends to include in the Series in order to fix the cost
of a future purchase or attempt to enhance return by, for example, participating
in an anticipated increase in the value of a security. The Series may purchase
put options to hedge against a decline in the market value of securities held in
the Series or in an attempt to enhance return. The Series may write (sell) put
and covered call options on securities in which they are authorized to invest.
The Series may also purchase put and call options, and write put and covered
call options on U.S. securities indexes. Stock index options serve to hedge
against overall fluctuations in the securities markets rather than anticipated
increases or decreases in the value of a particular security. Of the percentage
of the total assets of a Series that are invested in equity (or related)
securities, the Series may not invest more than 10% of such assets in covered
call options on securities and/or options on securities indices.


REPURCHASE AGREEMENTS. The Equity Series may invest in repurchase agreements,
which were previously described.


RESTRICTED SECURITIES. Restricted securities are securities that may not be sold
to the public without registration under the Securities Act of 1933 or an
exemption from registration. Each of the Equity Series may invest up to 15% of
its net assets in illiquid securities, subject to a Series' investment
limitations on the purchase of illiquid securities. Restricted securities,
including securities eligible for re-sale under 1933 Act Rule 144A, that are
determined to be liquid are not subject to this limitation. This determination
is to be made by the adviser or a sub-adviser pursuant to guidelines adopted by
the Board of Trustees. Under these guidelines, the adviser or a sub-adviser will
consider the frequency of trades and quotes for the security, the number of
dealers in, and potential purchasers for, the securities, dealer undertakings to
make a market in the security, and the nature of the security and of the
marketplace trades. In purchasing such restricted securities, the adviser or a
sub-adviser intends to purchase securities that are exempt from registration
under Rule 144A under the 1933 Act.


SECURITIES LENDING. The Equity Series may lend securities subject to the same
conditions applicable to the Bond Series. (See "Securities Lending" above).


(c) FUND POLICIES. Except as otherwise provided, the Equity Series have adopted
the investment limitations set forth below. Limitations which are designated as
fundamental policies may not be changed without the affirmative vote of the
lessor of (i) 67% or more of the shares of a Series present at a shareholders
meeting if holders of more than 50% of the outstanding shares of the Series are
present in person or by proxy or (ii) more than 50% of the outstanding shares of
a Series. If any percentage restriction on investment or utilization of assets
is adhered to at the time an investment is made, a later change in percentage
resulting from a change in the market values of a Series' assets or redemptions
of shares will not be considered a violation of the limitation.


Each Series will not as a matter of fundamental policy:


1. purchase the securities of any one issuer, if as a result, more than 5% of
the Series' total assets would be invested in the securities of such issuer, or
the Series would own or hold 10% or more of the outstanding voting securities of
that issuer, provided that (1) each Series may invest up to 25% of its total
assets without regard to these limitations; (2) these limitations do not apply
to securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities; and (3) for the WT Large Cap Growth, Large Cap Growth, Large
Cap Core, Small Cap Core and International Multi-Manager Series, repurchase
agreements fully collateralized by U.S. Government obligations will be treated
as U.S. Government obligations;

                                      B-19
<PAGE>

2. purchase securities of any issuer if, as a result, more than 25% of the
Series' total assets would be invested in the securities of one or more issuers
having their principal business activities in the same industry, provided, that
(1) for the Large Cap Value, Small Cap Value and Mid Cap Value Series, this
limitation does not apply to investments in short-term obligations issued or
guaranteed by the U.S. Government, its agencies or instrumentalities; and (2)
the Large Cap Growth, WT Large Cap Growth, Large Cap Core, Small Cap Core and
International Multi-Manager Series, this limitation does not apply to debt
obligations issued or guaranteed by the U.S. Government, its agencies or
instrumentalities;


3. borrow money, provided that (1) each of the Large Cap Value, Small Cap Value
and Mid Cap Value Series may borrow money for temporary or emergency purposes,
including the meeting of redemption requests, in amounts up to 33 1/3% of a
Series' assets; and (2) each of the Large Cap Growth, WT Large Cap Growth, Large
Cap Core, Small Cap Core and International Multi-Manager Series may borrow money
for temporary or emergency purposes, and then in an aggregate amount not in
excess of 10% of a Series' total assets;


4. make loans to other persons, except by (1) purchasing debt securities in
accordance with its investment objective, policies and limitations; (2) entering
into repurchase agreements; or (3) engaging in securities loan transactions;


5. underwrite any issue of securities, except to the extent that the Series may
be considered to be acting as underwriter in connection with the disposition of
any portfolio security;


6. purchase or sell real estate, provided that (1) the Large Cap Value, Small
Cap Value and Mid Cap Value Series additionally may not invest in any interest
in real estate except securities issued or guaranteed by corporate or
governmental entities secured by real estate or interests therein, such as
mortgage pass-throughs and collateralized mortgage obligations, or issued by
companies that invest in real estate or interests therein; (2) the Large Cap
Growth, WT Large Cap Growth, Large Cap Core, Small Cap Core and International
Multi-Manager Series each may invest in obligations secured by real estate or
interests therein or obligations issued by companies that invest in real estate
or interests therein, including real estate investment trusts;


7. purchase or sell physical commodities, provided that (1) the Large Cap Value,
Small Cap Value and Mid Cap Value Series additionally are restricted from
purchasing or selling contracts, options or options on contracts to purchase or
sell physical commodities and (2) the Large Cap Growth, WT Large Cap Growth,
Large Cap Core, Small Cap Core and International Multi-Manager Series each may
invest in purchase, sell or enter into financial options and futures, forward
and spot currency contracts, swap transactions and other derivative financial
instruments; or


8. issue senior securities, except to the extent permitted by the 1940 Act,
provided that each of the Large Cap Value, Small Cap Value and Mid Cap Value
Series may borrow money subject to its investment limitation on borrowing.


The following non-fundamental policies apply to each Series unless otherwise
indicated, and the Board of Trustees may change them without shareholder
approval. Each Series will not:


1. pledge, mortgage or hypothecate its assets except to secure indebtedness
permitted to be incurred by the Series, provided that (1) this limitation does
not apply to the Large Cap Growth, WT Large Cap Growth, Large Cap Core and Small
Cap Core Series; and (2) with respect to the Large Cap Value, Small Cap Value,
Mid Cap Value and International Multi-Manager Series, the deposit in escrow of
securities in connection with the writing of put and call options,
collateralized loans of securities and collateral arrangements with respect to
margin for future contracts are not deemed to be pledges or hypothecations for
this purpose;


                                      B-20
<PAGE>

2. make short sales of securities except short sales against the box;


3. purchase securities on margin except for the use of short-term credit
necessary for the clearance of purchases and sales of portfolio securities,
provided that Large Cap Value, Small Cap Value and Mid Cap Value Series may make
initial and variation margin deposits in connection with permitted transactions
in options without violating this limitation;

4. purchase portfolio securities if its outstanding borrowings exceed 5% of the
value of its total assets, provided that (1) the Large Cap Value, Small Cap
Value and Mid Cap Value Series may not borrow for purposes other than meeting
redemptions in an amount exceeding 5% of the value of its total assets at the
time the borrowing is made.

(d)      TEMPORARY DEFENSIVE POSITION.


Each of the Equity Series except Small Cap Core Series and International Multi
Manager Series is permitted to take a temporary defensive position by investing
without limit in commercial paper and other money market instruments rated in
one of the two highest ratings categories by a NRSRO.

ITEM 16. BROKERAGE ALLOCATION AND OTHER PRACTICES


(a) BROKERAGE TRANSACTIONS. The advisers and sub-advisers place all portfolio
transactions on behalf of each Series. Debt securities purchased and sold by the
Series are generally traded on the dealer market on a net basis (i.e., without
commission) through dealers acting for their own account and not as brokers, or
otherwise involve transactions directly with the issuer of the instrument. This
means that a dealer (the securities firm or bank dealing with a Series) makes a
market for securities by offering to buy at one price and sell at a slightly
higher price. The difference between the prices is known as a spread. When
securities are purchased in underwritten offerings, they include a fixed amount
of compensation to the underwriter.


Some of the advisers' other clients have investment objectives and programs
similar to that of the Series. Occasionally, recommendations made to other
clients may result in their purchasing or selling securities simultaneously with
the Series. Consequently, the demand for securities being purchased or the
supply of securities being sold may increase, and this could have an adverse
effect on the price of those securities. It is the policy of the advisers not to
favor one client over another in making recommendations or in placing

                                      B-30
<PAGE>

orders. In the event of a simultaneous transaction, purchases or sales are
averaged as to price, transaction costs are allocated between a Series and other
clients participating in the transaction on a pro rata basis and purchases and
sales are normally allocated between the Series and the other clients as to
amount according to a formula determined prior to the execution of such
transactions.

(b)      COMMISSIONS.

(c)      BROKERAGE SELECTION.


The primary objective of the advisers and sub-advisers in placing orders on
behalf of the Series for the purchase and sale of securities is to obtain best
execution at the most favorable prices through responsible brokers or dealers
and, where the spread or commission rates are negotiable, at competitive rates.
In selecting a broker or dealer, each adviser considers, among other things: (i)
the price of the securities to be purchased or sold; (ii) the rate of the spread
or commission; (iii) the size and difficulty of the order; (iv) the nature and
character of the spread or commission for the securities to be purchased or
sold; (v) the reliability, integrity, financial condition, general execution and
operational capability of the broker or dealer; and (vi) the quality of any
research or statistical services provided by the broker or dealer to the Series
or to the advisers.

ITEM 17. CAPITAL STOCK AND OTHER SECURITIES.

(a) CAPITAL STOCK. The Trust issues shares for each Series with a par value of
$.01 per share. The shares of each Series, when issued and paid for in
accordance with this registration statement, will be fully paid and
non-assessable shares, with equal, non-cumulative voting rights, except as
described below, and no preferences as to conversion, exchange, dividends,
redemptions or any other feature. Shareholders shall have the right to vote only
(i) for removal of Trustees, (ii) with respect to such additional matters
relating to the Trust as may be required by the applicable provisions of the
1940 Act, including Section 16(a) thereof, and (iii) on such other matters as
the Trustees may consider necessary or desirable. In addition, the shareholders
of each Series will be asked to vote on any proposal to change a fundamental
investment

                                      B-31
<PAGE>


policy (i.e. a policy that may be changed only with the approval of
shareholders) of that Series. All shares of the Trust entitled to vote on a
matter shall vote without differentiation between the separate Series on a
one-vote-per-share basis; provided however, if a matter to be voted on affects
only the interests of not all Series, then only the shareholders of such
affected Series shall be entitled to vote on the matter. If liquidation of the
Trust should occur, shareholders would be entitled to receive on a per class
basis the assets of the particular Series whose shares they own, as well as a
proportionate share of Trust assets not attributable to any particular class
then in existence. Ordinarily, the Trust does not intend to hold annual meetings
of shareholders, except as required by the 1940 Act or other applicable law. The
Trust's by-laws provide that meetings of shareholders shall be called for the
purpose of voting upon the question of removal of one or more Trustees upon the
written request of the holders of not less than 10% of the outstanding shares.

ITEM 21. CALCULATION OF PERFORMANCE DATA.


The performance of a Series may be quoted in terms of its yield and its total
return in advertising and other promotional materials. Performance data quoted
represents past performance and is not intended to indicate future performance.
Performance of the Series will vary based on changes in market conditions and
the level of each Series' expenses. These performance figures are calculated in
the following manner:


Money Market Series:


         A. Yield for a money market fund is the net annualized yield for a
specified 7 calendar days calculated at simple interest rates. Yield is
calculated by determining the net change, exclusive of capital changes, in the
value of a hypothetical pre-existing account having a balance of one share at
the beginning of the period, subtracting a hypothetical charge reflecting
deductions from shareholder accounts, and

                                      B-32
<PAGE>

dividing the difference by the value of the account at the beginning of the base
period to obtain the base period return. The yield is annualized by multiplying
the base period return by 365/7. The yield figure is stated to the nearest
hundredth of one percent.


         B. Effective Yield is the net annualized yield for a specified 7
calendar days assuming reinvestment of income or compounding. Effective yield is
calculated by the same method as yield except the yield figure is compounded by
adding 1, raising the sum to a power equal to 365 divided by 7, and subtracting
1 from the result, according to the following formula:


                     Effective yield = [(Base Period Return + 1) 365/7] - 1.


                  C. Tax-Equivalent Yield is the net annualized taxable yield
needed to produce a specified tax-exempt yield at a given tax rate based on a
specified 7-day period assuming a reinvestment of all dividends paid during such
period. Tax-equivalent yield is calculated by dividing that portion of the
Tax-Exempt Series' yield (computed as in the yield description above) which is
tax-exempt by 1 minus a stated income tax rate and adding the quotient to that
portion, if any, of the yield of the Tax-Exempt Series that is not tax-exempt.


         The following table, which is based upon federal income tax rates in
effect on the date of this Statement of Additional Information, illustrates the
yields that would have to be achieved on taxable investments to produce a range
of hypothetical tax-equivalent yields:

         A. Average Annual Total Return is the average annual compound rate of
return for the periods of one year, five years, ten years and the life of a
Series, where applicable, all ended on the last day of a recent calendar
quarter. Average annual total return quotations reflect changes in the price of
a Series' shares, if any, and assume that all dividends during the respective
periods were reinvested in Series shares. Average annual total return is
calculated by finding the average annual compound rates of return of a
hypothetical investment over such periods, according to the following formula
(average annual total return is then expressed as a percentage):


                                            T = (ERV/P)1/n - 1

                                      B-33
<PAGE>

       Where:   P        =       a hypothetical initial investment of $1,000


                T        =       average annual total return


                n        =       number of years


                ERV      =       ending redeemable value: ERV is the
value, at the end of the applicable period, of a hypothetical $1,000 investment
made at the beginning of the applicable period.


         B. Yield Calculations. From time to time, an Equity or Bond Series may
advertise its yield. Yield for these Series is calculated by dividing the
Series' investment income for a 30-day period, net of expenses, by the average
number of shares entitled to receive dividends during that period according to
the following formula:


YIELD = 2[((a-b)/cd + 1)6-1]


                  where:


a    =     dividends and interest earned during the period;


b    =     expenses accrued for the period (net of reimbursements);


c    =     the average daily number of shares outstanding during the period that
were entitled to receive dividends; and


d    =     the maximum offering price per share on the last day of the period.


The result is expressed as an annualized percentage (assuming semiannual
compounding) of the maximum offering price per share at the end of the period.


         Except as noted below, in determining interest earned during the period
(variable "a" in the above formula), pfpc calculates the interest earned on each
debt instrument held by a Series during the period by: (i) computing the
instrument's yield to maturity, based on the value of the instrument (including
actual accrued interest) as of the last business day of the period or, if the
instrument was purchased during the period, the purchase price plus accrued
interest; (ii) dividing the yield to maturity by 360; and (iii) multiplying the
resulting quotient by the value of the instrument (including actual accrued
interest). Once interest earned is calculated in this fashion for each debt
instrument held by the Series, interest earned during the period is then
determined by totaling the interest earned on all debt instruments held by the
Series.


         For purposes of these calculations, the maturity of a debt instrument
with one or more call provisions is assumed to be the next date on which the
instrument reasonably can be expected to be called or, if none, the maturity
date. In general, interest income is reduced with respect to debt instruments
trading at a premium over their par value by subtracting a portion of the
premium from income on a daily basis, and increased with respect to debt
instruments trading at a discount by adding a portion of the discount to daily
income.


         In determining dividends earned by any preferred stock or other equity
securities held by a Series during the period (variable "a" in the above
formula), PFPC accrues the dividends daily at their stated dividend rates.
Capital gains and losses generally are excluded from yield calculations.


         Because yield accounting methods differ from the accounting methods
used to calculate net investment income for other purposes, a Series' yield may
not equal the dividend income actually paid to

                                      B-34
<PAGE>

investors or the net investment income reported with respect to the Series in
the Fund's financial statements.


         Yield information may be useful in reviewing a Series' performance and
in providing a basis for comparison with other investment alternatives. However,
the Series' yields fluctuate, unlike investments that pay a fixed interest rate
over a stated period of time. Investors should recognize that in periods of
declining interest rates, the Series' yields will tend to be somewhat higher
than prevailing market rates, and in periods of rising interest rates, the
Series' yields will tend to be somewhat lower. Also, when interest rates are
falling, the inflow of net new money to the Series from the continuous sale of
their shares will likely be invested in instruments producing lower yields than
the balance of the Series' holdings, thereby reducing the current yields of the
Series. In periods of rising interest rates, the opposite can be expected to
occur.


Comparison of Series Performance. A comparison of the quoted performance offered
for various investments is valid only if performance is calculated in the same
manner. Since there are many methods of calculating performance, investors
should consider the effects of the methods used to calculate performance when
comparing performance of a Series with performance quoted with respect to other
investment companies or types of investments. For example, it is useful to note
that yields reported on debt instruments are generally prospective, contrasted
with the historical yields reported by a Series.

*        Previously  filed with the  Securities and Exchange  Commission  with
         Amendment No. 1 on Form N1-A on February 28, 997 and incorporated
         herein by reference.

ITEM 24.          PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND.

         None.

ITEM 25.          INDEMNIFICATION.

Reference is made to Article VII of the Registrant's Agreement and Declaration
of Trust (Exhibit 23(a)(1)) and to Article X of the Registrant's By-Laws
(Exhibit 23(b)), which are incorporated herein by reference. Pursuant to Rule
484 under the Securities Act of 1933, as amended, the Registrant furnishes the
following undertaking:

         "Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the

                                      B-2
<PAGE>

opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue."

ITEM 26.              BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISERS.
(i)      Wilmington Trust Company ("WTC"), a Delaware corporation, serves as
