SUMMARY
Northwestern Mutual Series Fund, Inc. ("Fund") is composed of eleven Portfolios
which operate as separate mutual funds. This section gives you an overview of
the investment objectives and strategies for each of the Portfolios. The summary
concludes with a brief identification of the main risks and performance
information for all of the Portfolios. More detailed information follows this
summary.
INVESTMENT OBJECTIVES AND STRATEGIES
SMALL CAP GROWTH STOCK PORTFOLIO The investment objective of the Small Cap
Growth Stock Portfolio is long-term growth of capital. The Portfolio will seek
to achieve this objective primarily by investing in the common stocks of
companies which can reasonably be expected to increase sales and earnings at a
pace which will exceed the growth rate of the U.S. economy over an extended
period.
AGGRESSIVE GROWTH STOCK PORTFOLIO The investment objective of the Aggressive
Growth Stock Portfolio is to achieve long-term appreciation of capital. This
Portfolio also attempts to meet this goal primarily by investing in the common
stocks of companies which can reasonably be expected to increase their sales and
earnings at a pace which will exceed the growth rate of the nation's economy
over an extended period.
INTERNATIONAL EQUITY PORTFOLIO The investment objective of the International
Equity Portfolio is long-term capital growth. It pursues its objective through a
flexible policy of investing in stocks and debt securities of companies and
governments outside the United States.
INDEX 400 STOCK PORTFOLIO The investment objective of the Index 400 Stock
Portfolio is to achieve investment results that approximate the performance of
the Standard & Poor's MidCap 400 Index ("S&P MidCap 400 Index"). The Portfolio
will attempt to meet this objective by investing in stocks included in the S&P
MidCap 400 Index.
GROWTH STOCK PORTFOLIO The investment objective of the Growth Stock Portfolio
is long-term growth of capital; current income is secondary. The Portfolio seeks
to achieve this objective by selecting investments in companies which have above
average earnings growth potential.
GROWTH AND INCOME STOCK PORTFOLIO The investment objectives of the Growth and
Income Stock Portfolio are long-term growth of capital and income. Ordinarily
the Portfolio pursues its investment objectives by investing primarily in
dividend-paying common stock.
INDEX 500 STOCK PORTFOLIO The investment objective of the Index 500 Stock
Portfolio is to achieve investment results that approximate the performance of
the Standard & Poor's 500 Composite Stock Price Index ("S&P 500 Index"). The
Portfolio attempts to meet this objective by investing in stocks included in the
S&P 500 Index.
BALANCED PORTFOLIO The investment objective of the Balanced Portfolio is to
realize as high a level of long-term total rate of return as is consistent with
prudent investment risk. Total rate of return consists of current income,
including dividends, interest and discount accruals, and capital appreciation.
The assets of the Balanced Portfolio will be invested in the stock, bond and
money market sectors as described for
Prospectus 2
<PAGE> 3
the Index 500 Stock, Select Bond and Money Market Portfolios. The mix of
investments among the three market sectors will be adjusted continuously.
HIGH YIELD BOND PORTFOLIO The investment objective of the High Yield Bond
Portfolio is to achieve high current income and capital appreciation. The
Portfolio invests primarily in fixed income securities that are rated below
investment grade by the major rating agencies. High yield fixed income
securities are commonly known as "junk bonds".
SELECT BOND PORTFOLIO The primary investment objective of the Select Bond
Portfolio is to provide as high a level of long-term total rate of return as is
consistent with prudent investment risk. Total rate of return consists of
current income, including interest and discount accruals, and capital
appreciation. A secondary objective is to seek preservation of shareholders'
capital. The Select Bond Portfolio's assets are invested primarily in bonds and
other debt securities with maturities generally exceeding one year.
MONEY MARKET PORTFOLIO The investment objective of the Money Market Portfolio
is to realize maximum current income consistent with liquidity and stability of
capital. The assets of the Money Market Portfolio are invested in money market
instruments and other debt securities with maturities generally not exceeding
one year.
MAIN RISKS
The eleven Portfolios present varying amounts of risk. The amount of investment
risk for a Portfolio depends on the types of securities in which the Portfolio
invests and the investment strategies it uses. All investments present some
risk. In this prospectus we have listed the Portfolios in the sequence that we
think reflects the relative risk they present. The Small Cap Growth Stock
Portfolio presents the most investment risk. The Money Market Portfolio presents
less investment risk than any of the others.
RISKS FOR STOCKS Stock prices have historically outperformed other asset
classes over the long term, but stock prices tend to go up and down more
dramatically over the shorter term. These price movements may result from
factors affecting individual companies, industries, or the stock market as a
whole. Each of the Portfolios (except the Money Market Portfolio) has express
authority to invest at least part of its assets in stocks. Investors in the
Portfolios will incur some or all of the risks associated with stocks to the
extent that the assets are so invested.
GROWTH STOCKS are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more
appreciation potential. This potential may or may not be realized and growth
stock prices tend to fluctuate more dramatically than the overall stock market.
These risks for growth stocks are presented most clearly by the operations of
the Small Cap Growth Stock, Aggressive Growth Stock and Growth Stock Portfolios.
These risks may also affect the performance of the other Portfolios that invest
in stocks.
VALUE STOCKS are selected because they seem attractively priced. The main risks
are that the price for a stock may turn out to have been too high, or the market
may not recognize the real value of the stock for a long time. The risks for
value stocks are presented most clearly by the operations of the Growth and
Income Stock Portfolio and the International Equity Portfolio. These risks may
also affect the performance of the other Portfolios that invest in stocks.
SMALL CAP STOCKS may involve greater risks because smaller companies often have
a limited track record, narrower markets and more limited managerial and
financial resources than larger, more established companies. The prices of these
stocks tend to be more volatile and the issuers face greater risk of business
failure. The risks for small cap stocks are presented most clearly by the
operations of the Small Cap Growth Stock and Aggressive Growth Stock Portfolios.
These risks may also affect the performance of the other Portfolios that invest
in stocks.
RISKS FOR FIXED INCOME SECURITIES Each of the Portfolios has express authority
to invest all or part of its assets in fixed income securities. Investors in the
Portfolios will incur some or all of the risks associated with fixed income
securities to the extent that the assets are so invested.
INTEREST RATE RISK Bond prices rise and fall in response to changes in market
interest rates. When interest rates rise, bond prices fall. This effect is
greater for longer term bonds, and relatively minor for short-term cash
instruments that are about to mature. Interest rate risk is presented most
clearly by the operations of the High Yield Bond, Select Bond and Balanced
Portfolios. This risk may also affect the performance of the other Portfolios
that invest in fixed income securities.
CREDIT RISK Bond prices reflect the risk of default. The credit rating assigned
to a fixed income issue generally reflects the credit risk. High yield fixed
income securities present more credit risk than investment grade issues. Credit
risk is presented most clearly by the operations of the High Yield Bond
Portfolio. Credit risk may also affect the performance of the other Portfolios
that invest in fixed income securities.

<PAGE> 4
RISKS FOR INTERNATIONAL SECURITIES Foreign securities present the investment
risks that are inherent in all investments in securities as well as an array of
special risk considerations, including currency risks. Some of these risks are
described in this prospectus. A longer description is included in the Statement
of Additional Information. The risks associated with foreign securities are
presented most clearly by the operations of the International Equity Portfolio.
The Growth and Income Stock, Balanced, Select Bond and High Yield Bond
Portfolios may also invest a portion of their assets in foreign securities and,
to that extent, the performance of those Portfolios may be affected by the
associated risks.
RISKS FOR FINANCIAL FUTURES CONTRACTS All of the Portfolios, except the Money
Market Portfolio, may use financial futures contracts in pursuit of their
investment objectives. These instruments are used as a hedge against changes in
the market value of common stocks or changes in prevailing levels of interest
rates. Successful use of these instruments requires special skills, knowledge
and techniques. Gains or losses from positions in financial futures contracts
may be much greater than the amounts invested.
ASSET ALLOCATION RISK In addition to the risks involved with each kind of
securities there is the risk that an investor will hold the wrong mix of
securities at any point in time. This risk is especially important for the
Balanced Portfolio, but it is a consideration for all of the Portfolios. It is
also likely to be the most important consideration for you as an individual
investor.
RISKS FOR ALL SECURITIES The value of a security on a given date depends
entirely on its market price. Investors necessarily rely on the integrity of the
marketplace. There is no guarantee that the securities markets will function in
an orderly manner. Illiquidity may make it difficult for a Portfolio to buy or
sell a security or to price the security fairly. The Year 2000 issue is a
consideration for all investors at this juncture, as discussed in this
prospectus.
MONEY MARKET PORTFOLIO An investment in the Money Market Portfolio is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. Although the Money Market Portfolio seeks to preserve the
value of your investment at $1.00 per share, it is possible to lose money by
investing in the Money Market Portfolio.
PERFORMANCE
The following bar charts illustrate the risks of investing in the Portfolios by
showing how the performance of each Portfolio (including predecessors) has
varied from year to year. These charts do not reflect the charges and expenses
for the variable annuity or variable life insurance separate account that
invests in the Portfolios. Total returns would be lower if those charges and
expenses were reflected. The tables to the right of the charts further
illustrate the risks of investing in the Portfolios by showing how each
Portfolio's average annual returns for the periods shown compare with the
returns of certain indexes that measure broad market performance.

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
The investment objectives, strategies and risks of each Portfolio are described
below.
The main risks for each kind of security are briefly identified above. See "Main
Risks", p. 3. Some of the risks are also discussed in the descriptions of the
Portfolios below.
The investment objective of a Portfolio may be changed only with the approval of
the majority of the Portfolio's shares outstanding. The details of the
investment policies of a Portfolio may be changed by the Fund's Board of
Directors without a vote of the shareholders. For example, such details include
investments in new types of debt instruments which may be devised in the future
or which are presently in disuse but may become more prominent in the future and
minor changes in investment policies which may be made in response to changes in
regulatory requirements which are reflected in the Portfolio's present policies.
Small Cap Growth Stock Portfolio
The investment objective of the Small Cap Growth Stock Portfolio is to achieve
long-term appreciation of capital. The Portfolio will seek to achieve this
objective primarily by investing in the common stocks of companies which can
reasonably be expected to increase their sales and earnings at a pace which will
exceed the growth rate of the nation's economy over an extended period. These
companies, for the most part, are small capitalization companies whose stock may
experience substantial price volatility. Under normal circumstances the
Portfolio will invest at least 80% of its assets in stocks.
In addition to common stocks, the Small Cap Growth Stock Portfolio may invest in
other equity securities such as preferred stocks and debt securities with
conversion privileges or warrants. A portion of the assets may be invested in
money market instruments, including U.S. Government and agency securities and
short-term commercial paper. When adverse conditions exist the Small Cap Growth
Stock Portfolio may be hindered in its pursuit of its investment objective
because it may not invest, or may invest less, in the common stocks in which it
ordinarily invests.
The Small Cap Growth Stock Portfolio may also invest in covered call option
contracts, stock index futures contracts, including indexes on specific
industries, repurchase agreements and warrants. A description of these
instruments is included in the Statement of Additional Information. Because the
Small Cap Growth Stock Portfolio will be investing in stocks which possess
substantial price volatility, an investment in the Small Cap Growth Stock
Portfolio will present more risk than an investment in any of the other
Portfolios.
Aggressive Growth Stock Portfolio
The investment objective of the Aggressive Growth Stock Portfolio is to achieve
long-term appreciation of capital. The Portfolio will seek to achieve this
objective primarily by investing in the common stocks of companies which can
reasonably be expected to increase their sales and earnings at a pace which will
exceed the growth rate of the nation's economy over an extended period. These
companies, for the most part, are mid-sized and smaller companies whose stock
may experience substantial price volatility. Under normal circumstances the
Portfolio will invest at least 80% of its assets in stocks.
In addition to common stocks, the assets of the Aggressive Growth Stock
Portfolio may be invested in other equity securities such as preferred stocks
and debt securities with conversion privileges or warrants. From time to time
assets may be invested in investment grade debt securities, short-term
commercial paper and United States Treasury obligations, or temporarily held in
cash uninvested for periods when the manager determines that economic conditions
call for such action. When adverse conditions exist the Aggressive Growth Stock
Portfolio may be hindered in its pursuit of its investment objective because it
may not invest, or may invest less, in the common stocks in which it ordinarily
invests. The Aggressive Growth Stock Portfolio may also invest in covered call
option contracts, stock index futures contracts, including indexes on specific
industries, repurchase agreements and warrants. A description of these
instruments is included in the Statement of Additional Information. Because the
Aggressive Growth Stock Portfolio will, for the most part, be investing in
stocks which possess substantial price volatility, an investment in the
Aggressive Growth Stock Portfolio will present more risk than an investment in
the Growth Stock Portfolio.
International Equity Portfolio
The International Equity Portfolio seeks long-term capital growth through a
flexible policy of investing in stocks and debt obligations of companies and
governments outside the United States. In pursuit of its investment objective,
the Portfolio will invest at least 65% of its assets in securities of issuers in
at least three countries outside the United States. Any income realized will be
incidental.
The strategy for the Portfolio will reflect a bottom-up, value-oriented and
long-term investment philosophy. In choosing
9 Prospectus
<PAGE> 10
equity investments, the Portfolio's manager will focus on the market price of a
company's securities in relation to the company's long-term earnings, asset
value and cash flow potential. A company's historical value measures, including
price/earnings ratio, profit margins and liquidation value, will also be
considered.
Although the Portfolio generally invests in common stocks, it may also invest in
preferred stocks and certain debt securities such as convertible bonds which are
rated in any category by Moody's Investors Service, Inc. or Standard & Poor's or
which are unrated by any rating agency. See Appendix in the Statement of
Additional Information for a description of the ratings presented by Moody's
Investors Service, Inc. and Standard & Poor's. The Statement of Additional
Information also includes a longer discussion of the risks presented by
investments in foreign securities.
For temporary defensive purposes, the Portfolio may invest without limit in
commercial paper, certificates of deposit, bank time deposits in the currency of
any nation, bankers acceptances, U.S. Government securities, corporate debt
obligations, and repurchase agreements with respect to these securities. When
adverse conditions exist the International Equity Portfolio may be hindered in
its pursuit of its investment objective because it may not invest, or may invest
less, in the international stocks in which it ordinarily invests.
The International Equity Portfolio may purchase and sell financial futures
contracts, stock index futures contracts, and foreign currency futures contracts
for hedging purposes only and not for speculation. It may engage in such
transactions only if the total contract value of the futures contracts does not
exceed 20% of the Portfolio's total assets. Financial futures contracts are
described in the Statement of Additional Information.
The International Equity Portfolio has an unlimited right to purchase securities
in any foreign country, developed or underdeveloped. Before investing in the
Portfolio, you should consider carefully the risks involved in investing in
securities issued by companies and governments of foreign nations, which are in
addition to the usual risks inherent in domestic investments. There is the
possibility of expropriation, nationalization or confiscatory taxation, taxation
of income earned in foreign nations (including withholding taxes) or other taxes
imposed with respect to investments in foreign nations, foreign exchange
controls (which may include suspension of the ability to transfer currency from
a given country), default in foreign government securities, political or social
instability or diplomatic developments which could affect investments in
securities or issuers in those nations.
These considerations generally are more of a concern in developing countries,
where the possibility of political instability (including revolution) and
dependence on foreign economic assistance may be greater than in developed
countries. Investments in companies domiciled in developing countries therefore
may be subject to potentially higher risks than investments in developed
countries.
In many countries there is less publicly available information about issuers
than is available in reports about companies in the United States. Foreign
companies are not generally subject to uniform accounting and auditing and
financial reporting standards, and auditing practices and requirements may not
be comparable to those applicable to United States companies. It may be more
difficult to obtain or enforce judgments obtained against foreign entities.
Commission rates in foreign countries, which are generally fixed rather than
subject to negotiation as in the United States, are likely to be higher.
Further, the settlement period of securities transactions in foreign markets may
be longer than in domestic markets.
In many foreign countries there is less government supervision and regulation of
business and industry practices, stock exchanges, brokers and listed companies
than in the United States. Foreign securities transactions may be subject to
higher brokerage costs than domestic securities transactions. Foreign securities
often trade with less frequency and volume than domestic securities and are
therefore less liquid and more volatile than securities of comparable domestic
issuers. The International Equity Portfolio may invest in Russia. This involves
special risks that are described in the Statement of Additional Information.
Index 400 Stock Portfolio
The investment objective of the Index 400 Stock Portfolio is to achieve
investment results that approximate the performance of the S&P MidCap 400 Stock
Price Index ("S&P MidCap 400 Index"). The Portfolio will attempt to meet this
objective by investing in stocks included in the S&P MidCap 400 Index in
proportion to their weighting in the index.
The S&P MidCap 400 Index is composed of 400 common stocks. The companies
included in the S&P MidCap 400 Index are generally smaller than those that
comprise the S&P 500 Index. See the description of the Index 500 Stock Portfolio
below. The S&P MidCap 400 does not include the very large issues that account
for most of the weighting in the S&P 500 Index. Most of the companies in the S&P
MidCap 400 Index have a market value in the range of $750 million to $5 billion.
A few are smaller and a few are larger. "Standard & Poor's(R)", "S&P(R)", "S&P
MidCap 400 Index" and "Standard & Poor's MidCap 400" are trademarks of The
McGraw-Hill Companies, Inc. and have been licensed for use by Northwestern
Mutual. The Fund is not sponsored, endorsed, sold or promoted by Standard &
Poor's and Standard & Poor's makes no representation regarding the advisability
of investing in the Fund.
Prospectus 10
<PAGE> 11
The Index 400 Stock Portfolio will not be managed in the traditional sense using
economic, financial and market analysis. A computer program will be used to
determine which stocks are to be purchased or sold to achieve the Portfolio's
objective. The Portfolio will, to the extent feasible, remain fully invested and
will normally hold at least 375 of the 400 issues that comprise the S&P MidCap
400 Index.
The Index 400 Stock Portfolio's ability to match the performance of the S&P
MidCap 400 Index will be affected to some extent by the size and timing of cash
flows into and out of the Index 400 Stock Portfolio. The Portfolio will be
managed with a view to reducing such effects. A portion of the assets may at
times be invested in investment grade debt securities, short term commercial
paper and Government and agency obligations, as well as option contracts, stock
index futures contracts, and repurchase agreements.
Growth Stock Portfolio
The investment objective of the Growth Stock Portfolio is long-term growth of
capital; current income is secondary. The Portfolio will seek to achieve this
objective by selecting investments in companies which have above average
earnings growth potential.
The Growth Stock Portfolio invests primarily in common stocks of
well-established companies, with emphasis placed on high quality companies with
strong financial characteristics. The investment process is initiated with a
fundamental economic outlook. Further study of economic sectors leads to the
identification of growth-oriented industries, and to detailed studies of
individual companies. In evaluating individual companies, factors such as the
company management team, product outlook, global exposure, industry leadership
position, and financial characteristics are important variables used in the
analysis.
The market capitalization of companies the Portfolio may invest in is not
limited by size, but the Portfolio will generally invest in large- and
medium-sized companies. The aim of the Portfolio is to seek to reduce overall
risk by diversifying its assets in an appropriate manner. This diversification
will span economic sectors, industry groups, and companies, while emphasizing
high quality investments.
The Portfolio may invest in any of the securities in which the Growth and Income
Stock Portfolio or the Aggressive Growth Stock Portfolio may invest, including,
but not limited to, preferred stock, convertible bonds, short-term commercial
paper, and covered call options. When adverse conditions exist the Growth Stock
Portfolio may be hindered in its pursuit of its investment objective because it
may not invest, or may invest less, in the common stocks in which it ordinarily
invests.
Portfolios emphasizing growth-oriented investments may experience above average
price volatility. An investment in the Growth Stock Portfolio can present more
risk than an investment in the Index 500 Stock Portfolio. The Growth Stock
Portfolio is designed for long-term investors seeking capital appreciation.
Growth and Income Stock Portfolio
The investment objectives of the Growth and Income Stock Portfolio are long-term
growth of capital and income. The Portfolio seeks to achieve these objectives
consistent with reasonable investment risk. Ordinarily, the Portfolio pursues
its investment objectives by investing primarily in dividend-paying common
stock. The Portfolio may also invest in other equity securities, consisting of,
among other things, nondividend-paying common stock, preferred stock, and
securities convertible into common stock, such as convertible preferred stock
and convertible bonds, and warrants. The Portfolio may also invest in American
Depository Receipts (ADRs).
The Portfolio is not subject to any limit on the size of companies in which it
may invest, but intends, under normal circumstances, to be fully invested to the
extent practicable primarily in the large- and medium-sized companies included
in the S&P 500 Index. The Portfolio is designed for investors who want an
actively managed equity portfolio that seeks to outperform the total return of
the S&P 500 Index. In managing the Portfolio, the potential for appreciation and
dividend growth is given more weight than current dividends. Nonetheless, the
manager of the Portfolio will normally strive for gross income for the Portfolio
at a level not less than 75% of the dividend income generated on the stocks
included in the S&P 500 Index, although this income level is merely a guideline
and there can be no certainty that this income level will be achieved.
The Portfolio does not seek to achieve its objective with any individual
investment security, but rather it aims to manage all of its assets in such a
way as to achieve its objective. The Portfolio attempts to reduce risk by
investing in many different economic sectors, industries and companies. The
manager of the Portfolio may moderately under- or over-weight selected economic
sectors against the sector weightings of the S&P 500 Index to seek to enhance
the Portfolio's total return or reduce fluctuations in market value relative to
the S&P 500 Index. In selecting securities, the manager may emphasize securities
that it believes to be undervalued. Securities of a company may be undervalued
for a variety of reasons such as an overreaction by investors to unfavorable
news about a company, an industry or the stock markets in general; or as a
result of a market decline, poor economic conditions, tax-loss selling, or
actual or anticipated unfavorable developments affecting a company.
11 Prospectus
<PAGE> 12
During ordinary market conditions, the Portfolio will be as fully invested as
practicable in the equity securities described above. The Portfolio may enter
into firm commitment agreements, purchase securities on a "when-issued" basis,
and invest in various foreign securities if U.S. exchange-listed. The Portfolio
may also invest in money market instruments, including U.S. Government
securities, short term bank obligations that are rated in the highest two rating
categories by Moody's Investors Service, Inc. or Standard & Poor's, or, if
unrated, are determined to be of equal quality by the manager of the Portfolio,
certificates of deposit, time deposits and banker's acceptances issued by U.S.
and foreign banks and savings and loan institutions with assets of at least $500
million as of the end of their most recent fiscal year; and commercial paper and
corporate obligations, including variable rate demand notes, that are issued by
U.S. and foreign issuers and that are rated in the highest two rating categories
by Moody's Investors Service, Inc. or Standard & Poor's, or if unrated, are
determined to be of equal quality by the manager of the Portfolio. A description
of these ratings is included in the Statement of Additional Information. Under
normal circumstances, the Portfolio will invest in such money market instruments
to invest temporary cash balances or to maintain liquidity to meet redemptions
or expenses. The Portfolio may also, however, invest in these instruments,
without limitation, as a temporary defensive measure taken during, or in
anticipation of, adverse market conditions. When adverse conditions exist the
Growth and Income Stock Portfolio may be hindered in its pursuit of its
investment objective because it may not invest, or may invest less, in the
common stocks in which it ordinarily invests.
Convertible bonds and other fixed income securities (other than money market
instruments) in which the Portfolio may invest will, at the time of investment,
be rated Baa or better by Moody's Investors Service, Inc. or BBB or better by
Standard & Poor's or, if not so rated, will be of comparable quality as
determined by the manager of the Portfolio. A description of these ratings is
included in the Statement of Additional Information. In the event that an
existing holding is downgraded below these ratings, the Portfolio may
nonetheless retain the security.
In pursuing its investment objective, the Portfolio may engage in the purchase
and writing of put and call options on securities and stock indexes and may
purchase or sell stock index futures contracts and options thereon. These
investment techniques may involve a greater degree of risk than those inherent
in more conservative investment approaches. See the Statement of Additional
Information for a description of these techniques and their attendant risks.
Index 500 Stock Portfolio
The investment objective of the Index 500 Stock Portfolio is to achieve
investment results that approximate the performance of the Standard & Poor's 500
Composite Stock Price Index ("S&P 500 Index"). The Portfolio will attempt to
meet this objective by investing in stocks included in the S&P 500 Index in
proportion to their weighting in the index.
The S&P 500 Index is composed of 500 common stocks representing more than 70% of
the total market value of all publicly-traded common stocks. "Standard &
Poor's(R)", "S&P(R)", "S&P 500(R)", "Standard & Poor's 500", and "500" are
trademarks of The McGraw-Hill Companies, Inc. and have been licensed for use by
Northwestern Mutual. The Fund is not sponsored, endorsed, sold or promoted by
Standard & Poor's and Standard & Poor's makes no representation regarding the
advisability of investing in the Fund.
The Index 500 Stock Portfolio will not be managed in the traditional sense using
economic, financial and market analysis. A computer program will be used to
determine which stocks are to be purchased or sold to achieve the Portfolio's
objective. The Portfolio will, to the extent feasible, remain fully invested and
will normally hold at least 450 of the 500 issues that comprise the S&P 500
Index.
The Index 500 Stock Portfolio's ability to match the performance of the S&P 500
Index will be affected to some extent by the size and timing of cash flows into
and out of the Index 500 Stock Portfolio. The Portfolio will be managed with a
view to reducing such effects. A portion of the assets may at times be invested
in investment grade debt securities, short term commercial paper and United
States Treasury obligations, as well as option contracts, stock index futures
contracts, and repurchase agreements.
Balanced Portfolio
The investment objective of the Balanced Portfolio is to realize as high a level
of long-term total rate of return as is consistent with prudent investment risk.
Total rate of return consists of current income, including dividends, interest
and discount accruals, and capital appreciation.
The assets of the Balanced Portfolio will be invested in the following three
market sectors:
1. Common stock and other equity securities including the securities in which
the Index 500 Stock Portfolio invests.
2. Bonds and other debt securities with maturities generally exceeding one year
including the securities in which the Select Bond Portfolio invests.
Prospectus 12
<PAGE> 13
3. Money market instruments and other debt securities with maturities generally
not exceeding one year including the securities in which the Money Market
Portfolio invests.
The Balanced Portfolio seeks to achieve its investment objectives by
continuously adjusting the mix of investments among the three market sectors.
The manager attempts to capitalize on variation in return potential produced by
the interaction of changing financial markets and economic conditions. Asset
allocation decisions are based on fundamental analysis rather than short-term
market timing considerations. Shifts in asset allocation are expected to be
gradual.
The Portfolio will normally have some portion of its assets invested in each of
the three asset categories. However, up to 100% of the Balanced Portfolio's net
assets may be invested in money market instruments. Not more than 75% of the
Balanced Portfolio's net assets may be invested in either the stock sector or
the bond sector. No minimum percentage has been established for any of the
sectors. The Balanced Portfolio's investment objective is supplemented by
investment objectives and policies for the stock, bond and money market sectors.
These are presently substantially identical to those which have been established
for the Index 500 Stock, Select Bond and Money Market Portfolios.
High Yield Bond Portfolio
The investment objective of the High Yield Bond Portfolio is to achieve high
current income and capital appreciation.
The High Yield Bond Portfolio seeks to achieve its objective by investing
primarily in a diversified selection of fixed income securities rated Ba1 or
lower by Moody's Investors Service, Inc. or BB+ or lower by Standard & Poor's. A
description of the ratings provided by the major rating agencies is included in
the Statement of Additional Information. The Portfolio may also invest in
nonrated securities.
The securities in which the High Yield Bond Portfolio will invest are considered
speculative and are sometimes known as "junk bonds". These securities tend to
offer higher yields than higher rated securities of comparable maturities
because the historical financial condition of the issuers of these securities is
usually not so strong as that of other issuers. High yield fixed income
securities usually present greater risk of loss of income and principal than
higher rated securities. Investors in these securities should carefully consider
these risks and should understand that high yield fixed income securities are
not appropriate for short-term investment purposes.
The primary investment strategy of the High Yield Bond Portfolio is to invest in
industries or individual companies which have stable or improving fundamental
financial characteristics. The success of this strategy depends on the manager's
analytical and portfolio management skills. These skills are more important in
the selection of high yield/high risk securities than would be the case with a
portfolio of high quality bonds. In selecting securities for the High Yield Bond
Portfolio the manager will consider the ratings assigned by the major rating
agencies, but primary reliance will be placed on the manager's evaluation of
credit and market risk in relationship to the expected rate of return.
The risk that the issuer of a fixed income security may fail to pay principal
and interest when due is referred to as "credit risk". Price volatility caused
by such factors as interest rate fluctuation, market perceptions of an issuer's
creditworthiness and general liquidity in the financial market is "market risk".
The value of the securities held by the High Yield Bond Portfolio will be
directly affected by the market perception of the creditworthiness of the
securities' issuers and will fluctuate inversely with changes in interest rates.
Lower rated securities are more likely to react to developments affecting market
and credit risk than are more highly rated securities, which react primarily to
movements in the general level of interest rates. For example, because investors
generally perceive that there are greater risks associated with investing in
medium or lower rated securities, the yields and prices of such securities may
tend to fluctuate more than those of higher rated securities. Moreover, in the
lower quality segments of the fixed income securities market, changes in
perception of the creditworthiness of individual issuers tend to occur more
frequently and in a more pronounced manner than do changes in higher quality
segments of the fixed income securities market. The yield and price of medium to
lower rated securities therefore may experience greater volatility than is the
case with higher rated securities. The manager of the Portfolio seeks to reduce
volatility through careful evaluation of credit risk and market risk and
diversification of the Portfolio's investments.
The secondary market for high yield/high risk securities, which is concentrated
in relatively few market makers, may not be as liquid as the secondary market
for more highly rated securities. Under adverse market or economic conditions,
the secondary market for high yield/high risk securities could contract further,
independent of any specific adverse changes in the condition of a particular
issuer. As a result, the High Yield Bond Portfolio could find it more difficult
to sell such securities or may be able to sell the securities only at prices
lower than if such securities were widely traded. Prices realized upon the sale
of such lower rated securities therefore may be less than the prices used in
calculating the Portfolio's net asset value. In the absence of readily available
market quotations, high yield/high risk securities will be valued by the Fund's
Directors using a method that, in the good faith belief of the Directors,
accurately reflects fair value. Valuing such securities in an illiquid market is
a
13 Prospectus
<PAGE> 14
difficult task. The Directors' judgment plays a more significant role in valuing
such securities than those securities for which more objective market data are
available.
In addition to notes and bonds, the High Yield Bond Portfolio may invest in
preferred stocks and convertible securities, including warrants or other equity
securities issued as part of a fixed income offering. The Portfolio may also
invest up to 5% of its assets in other equity securities, rights, warrants,
options and other derivatives. The Portfolio may purchase put and call options,
on individual securities as well as indexes, and may write covered call and
secured put options. A description of put and call options is included in the
Statement of Additional Information. The Portfolio may invest available
temporary cash in short-term obligations, including those in which the Money
Market Portfolio may invest. The Portfolio may invest more substantially in such
short-term obligations or in investment grade securities (rated Baa3 or higher
by Moody's Investors Service, Inc. or BBB-or higher by Standard & Poor's) when
market conditions warrant a more defensive investment posture. When adverse
conditions exist the High Yield Bond Portfolio may be hindered in its pursuit of
its investment objective because it may not invest, or may invest less, in the
high yield/high risk securities in which it ordinarily invests.
The High Yield Bond Portfolio may invest in foreign securities consistent with
its investment objective. Some of the risks associated with investments in
foreign securities are briefly set forth in the description of the International
Equity Portfolio above. Such investments may be in United States currency
denominated debt issues or in debt securities in the currency of other nations.
The Portfolio may, but will not necessarily, attempt to hedge its exposures by
engaging in transactions in foreign currency futures contracts. For a discussion
of the risks involved in these contracts see the Statement of Additional
Information.
Select Bond Portfolio
The primary investment objective of the Select Bond Portfolio is to provide as
high a level of long-term total rate of return as is consistent with prudent
investment risk. Total rate of return consists of current income, including
interest and discount accruals, and capital appreciation. A secondary objective
is to seek preservation of shareholders' capital.
The Select Bond Portfolio's assets will be invested in the following types of
securities:
1. publicly offered straight debt securities having a rating within the four
highest grades as determined by Moody's Investors Service, Inc. (Aaa, Aa, A
or Baa) or Standard & Poor's (AAA, AA, A or BBB);
2. obligations of or guaranteed by the United States Government or its agencies;
3. obligations (payable in U.S. dollars) of or guaranteed by the Government of
Canada or of a Province of Canada or any instrumentality or political
subdivision thereof, provided such obligations have a rating within the three
highest grades as determined by Moody's Investors Service, Inc. or Standard &
Poor's and do not exceed 10% of the Portfolio's total assets;
4. publicly offered straight debt securities issued or guaranteed by a national
or state bank or bank holding company (as defined in the Federal Bank Holding
Company Act, as amended) having a rating within the two highest grades as
determined by Fitch's Investor's Service, Inc. (AAA or AA), and certificates
of deposit of such banks or bank holding companies;
5. commercial paper having a rating within the two highest investment grades, as
determined by Moody's Investors Service, Inc. (P-1 or P-2) or Standard &
Poor's (A-1 or A-2);
6. straight debt securities acquired directly from the issuers in private
placement transactions, which securities, in the judgment of the Fund's Board
of Directors, are of investment quality comparable to publicly offered
straight debt securities rated Baa by Moody's Investors Service, Inc. or BBB
by Standard & Poor's, or better;
7. cash or cash equivalents; and
8. preferred stocks and obligations not described above, including convertible
securities, securities carrying warrants to purchase equity securities and
securities acquired directly from the issuers in private placement
transactions other than those securities described above.
A description of the ratings provided by Moody's Investors Service, Inc.,
Standard & Poor's and Fitch's Investor's Service, Inc. is included in the
Statement of Additional Information.
The Select Bond Portfolio will not invest in common stocks directly, but may
retain up to 10% of its total assets in common stocks acquired upon conversion
of debt securities or upon exercise of warrants acquired with debt securities.
At least 70% of the Select Bond Portfolio's total assets will normally be
invested in bonds and debentures which have maturities of at least one year.
However, during periods of particular volatility or when an unusual decline in
the value of long-term obligations is anticipated, for temporary defensive
purposes the Select Bond Portfolio may place a larger portion of its assets in
cash and short-term obligations. During such periods the Select Bond Portfolio's
holdings of
Prospectus 14
<PAGE> 15
short-term obligations and equity securities may temporarily exceed an aggregate
total of 30% of the Select Bond Portfolio's total assets. When adverse
conditions exist the Select Bond Portfolio may be hindered in its pursuit of its
investment objective because it may not invest, or may invest less, in the
longer-term bonds and debentures in which it ordinarily invests.
The Select Bond Portfolio invests in obligations of a number of U.S. Government
agencies. Obligations of some agencies are supported by the full faith and
credit of the U.S. Treasury, others are supported only by the credit of the
agency. No assurance can be given that the U.S. Government would provide
financial support to any agency if it is not obligated to do so by law. The
Select Bond Portfolio will invest in the securities of a particular agency only
when the investment adviser is satisfied that the credit risk with respect to
such agency is minimal.
The Select Bond Portfolio may invest up to 10% of its total assets in high
yield/high risk securities and up to 10% of its total assets in foreign
securities, consistent with its investment objectives. See the description of
the High Yield Bond Portfolio, p. 13 for a discussion of high yield/high risk
securities. Some of the risks associated with investments in foreign securities
are briefly set forth in the description of the International Equity Portfolio,
p. 9.
The Select Bond Portfolio may also invest in interest rate futures contracts and
repurchase agreements. The Statement of Additional Information includes a
description of these instruments.
Money Market Portfolio
The investment objective of the Money Market Portfolio is to realize maximum
current income to the extent consistent with liquidity and stability of capital.
The assets of the Money Market Portfolio will be invested in money market
instruments and other debt securities with maturities generally not exceeding
one year. Such instruments may include the following:
1. U.S. Treasury Bills and other obligations of or guaranteed by the U.S.
Government or its agencies;
2. obligations of or guaranteed by the Government of Canada or of a Province of
Canada or any instrumentality or political subdivision thereof, provided such
obligations do not exceed 10% of the Money Market Portfolio's total assets;
3. obligations (including certificates of deposit, time deposits, or bankers'
acceptances) of U.S. or Canadian chartered banks having total assets in
excess of $1,000,000,000, U.S. branches of foreign banks where said foreign
banks have total assets in excess of $10,000,000,000, and U.S. savings and
loan associations having total assets in excess of $1,000,000,000, and
Eurodollar certificates of deposit issued by foreign branches of U.S. banks
where said banks have total assets in excess of $1,000,000,000 (see
"Eurodollar Certificates of Deposit");
4. commercial paper, including variable amount master notes, having a rating at
the time of purchase within the two highest grades as determined by Moody's
Investors Service, Inc. (P-1 or P-2) or Standard & Poor's (A-1 or A-2), or
commercial paper or notes issued by companies with an unsecured debt issue
outstanding having a rating at the time of purchase within the three highest
grades as determined by Moody's Investors Service, Inc. (Aaa, Aa, or A) or
Standard & Poor's (AAA, AA or A); and
5. publicly traded bonds, debentures and notes having a rating within the four
highest grades as determined by Moody's Investors Service, Inc. (Aaa, Aa, A
or Baa) or Standard & Poor's (AAA, AA, A or BBB).
A glossary of the following terms is included in the Statement of Additional
Information: certificates of deposit, Eurodollar certificates of deposit, time
deposits, bankers' acceptances, variable amount master notes and commercial
paper. A description of the ratings provided by Moody's Investors Service, Inc.
and Standard & Poor's is also included in the Statement of Additional
Information.
The Money Market Portfolio will attempt to maximize its return by trading to
take advantage of changing money market conditions and trends. The Money Market
Portfolio will also trade to take advantage of what are believed to be
disparities in yield relationships between different money market instruments.
This procedure may increase or decrease the Portfolio's yield depending upon
management's ability to correctly time and execute such transactions. The Money
Market Portfolio intends to purchase only securities that mature within a year
except for securities which are subject to repurchase agreements. Accordingly,
the level of purchases will be relatively high. However, as transaction costs on
Money Market Portfolio investments are generally not substantial, the high level
of purchases will not adversely affect the Portfolio's net asset value or net
income.
U.S. Government and agency obligations held by the Money Market Portfolio
consist primarily of discounted or interest-bearing notes with average
maturities of ninety days or less. The Money Market Portfolio invests most
frequently in obligations of the following agencies of the U.S. Government: Farm
Credit System, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation
and Federal National Mortgage Association. Obligations of some agencies
15 Prospectus
<PAGE> 16
are supported by the full faith and credit of the U.S. Treasury, others are
supported by the right of the issuer to borrow from the Treasury, others, such
as those of the Federal National Mortgage Association, a private corporation,
are supported by the discretionary authority of the U.S. Government to purchase
the agency's obligations and others are supported only by the credit of the
agency. No assurance can be given that the U.S. Government would provide
financial support to any agency if it is not obligated to do so by law. The
Money Market Portfolio will invest in the securities of a particular agency only
when the investment adviser is satisfied that the credit risk with respect to
such agency is minimal.
The Money Market Portfolio may also invest in repurchase agreements. These are
described in the Statement of Additional Information.

TAXES AND DIVIDENDS
Each Portfolio is qualified or intends to qualify as a regulated investment
company under Subchapter M of the Internal Revenue Code. It is the Fund's policy
to comply with the provisions of the Code regarding distribution of investment
income and capital gains so as to relieve each Portfolio from all, or
substantially all, Federal taxes. Each Portfolio expects to distribute all or
substantially all net investment income and net capital gains, if any, from the
sale of investments.
Shareholders of each Portfolio are entitled to receive such dividends from net
investment income and distributions of net capital gains as the Directors of the
Fund may declare. Dividends from net investment income and net capital gains
will be declared for the Small Cap Growth Stock, Aggressive Growth Stock,
International Equity, Index 400 Stock, Growth Stock, Growth and Income Stock,
Index 500 Stock, Balanced, High Yield Bond and Select Bond Portfolios annually,
and for the Money Market Portfolio on each business day.
17 Prospectus
<PAGE> 18
Net investment income of each Portfolio will be determined at the close of
trading on the New York Stock Exchange on each day during which the Exchange is
open for trading. Net investment income of each Portfolio consists of:
1. all dividends, interest income and discount earned by the Portfolio
(including original issue and market discount) and
2. net short-term capital gain less
3. all expenses of the Portfolio.
Shares of the Portfolios are offered only for funding variable annuity contracts
and variable life insurance policies offered by The Northwestern Mutual Life
Insurance Company. For a discussion of the tax considerations that affect the
insurance company and its separate accounts for these products, and the tax
considerations for purchasers of variable annuities and variable life insurance,
see the prospectus to which this prospectus for the Fund is attached.
- --------------------------------------------------------------------------------
OFFERING AND REDEMPTION OF SHARES
Shares of capital stock of each Portfolio of the Fund are offered and redeemed
at their net asset value as next determined following receipt of a purchase
order or tender for redemption without the addition of any selling commission or
"sales load" or any redemption charge. The redemption price may be more or less
than the shareholder's cost.
Equity securities listed on a stock exchange are valued at the closing sale
price or, if no sale took place, the closing bid price. Stock index futures
contracts and interest rate futures contracts are valued at the closing
settlement price on the commodities exchange. Debt securities with maturities
generally exceeding one year are valued on the basis of valuations furnished by
Interactive Data Corporation. Money market instruments with maturities exceeding
60 days but generally not exceeding one year are valued by marking to market,
except for the Money Market Portfolio. Debt securities with remaining maturities
of 60 days or less, and all debt securities of the Money Market Portfolio, are
valued on an amortized cost basis or, if the current market value differs
substantially from the amortized cost, by marking to market. All other assets
are valued at their fair value as determined in good faith by the Directors. Net
asset value is determined as of the close of trading on the New York Stock
Exchange on each day during which the Exchange is open for trading. In
accordance with the requirements of the Investment Company Act of 1940 the
Portfolios will also determine the net asset value of their shares on any other
day on which there is sufficient trading to materially affect the value of their
securities.
A more detailed discussion of asset valuation methods is included in the
Statement of Additional Information.

4. Invest more than 15% of the value of the total assets of the
Portfolio in securities which are restricted as to disposition
under federal securities laws and in other illiquid assets.
For the Money Market Portfolio the limit is 10%.
5. Invest more than 25% of the value of the total assets of the
Portfolio in securities of issuers in any one industry except
for investments by the Money Market Portfolio and the Balanced
Portfolio in U.S. Treasury Bills, other obligations of or
guaranteed by the U.S. Government or its agencies,
certificates of deposit or bankers' acceptances.
6. Make loans aggregating more than 10% of the total assets of
the Portfolio at any one time, provided that neither the
purchase of a portion of an issue of publicly distributed
bonds, debentures, or other debt securities, nor the purchase
of short-term debt securities, is to be considered as a loan.
7. Invest for the purpose of influencing management or exercising
control, but freedom of action is reserved with respect to
exercise of voting rights in respect of each Portfolio's
securities.
8. Purchase any security on margin, but each Portfolio may obtain
such short-term credits as are necessary for the clearance of
purchases and sales of securities.
9. Make short sales of securities.
10. Act as a securities underwriter for other issuers, but each
Portfolio may purchase securities under circumstances where,
if the securities are later publicly offered or sold by the
Portfolio, it might be deemed to be an underwriter for
purposes of the Securities Act of 1933.
11. Purchase or sell real estate. However, each Portfolio may
invest in securities issued by companies, including real
estate investment trusts, which invest in real estate or
interests therein.
B-3
<PAGE> 23
12. Invest in commodities or commodity contracts. However, each
Portfolio (except the Select Bond, Money Market and High Yield
Bond Portfolios) may invest in stock index futures contracts,
including indexes on specific industries, and the Select Bond,
High Yield Bond, International Equity and Balanced Portfolios
may invest in interest rate futures contracts in accordance
with their investment objectives and policies. The
International Equity and High Yield Bond Portfolios may invest
in foreign currency futures contracts.
13. Issue senior securities or borrow money except for short-term
credits as may be necessary for the clearing of transactions
and except for temporary purposes to the extent of 5% of the
total assets of the Portfolio. Reverse repurchase agreements
and financial futures contracts are not considered to be
"senior securities" or "borrowing money" for the purpose of
this restriction.
14. Make loans to persons who intend to use the proceeds for
non-business purposes or to companies which (including
predecessors) have been in business for less than three years.
Repurchase agreements are not considered to be "loans" for the
purpose of this restriction.
As a non-fundamental investment policy, which may be changed by the
Board of Directors without shareholder approval, the International Equity
Portfolio will not invest more than 15% of its total assets in securities of
foreign issuers which are not listed on a recognized United States or foreign
securities exchange.
REPURCHASE AGREEMENTS
Each of the Portfolios may invest in repurchase agreements. A
repurchase agreement customarily obligates the seller at the time it sells
securities to the Portfolio to repurchase the securities at a mutually agreed
upon time and price. The total amount received on repurchase would be calculated
to exceed the price paid by the Portfolio, reflecting an agreed upon market rate
of interest for the period from the time of the repurchase agreement to the
settlement date, and would not necessarily be related to the interest rate on
the underlying securities. The differences between the total amount to be
received upon repurchase of the securities and the price which was paid by the
Portfolio upon their acquisition is accrued as interest and is included in the
Portfolio's net income declared as dividends. Each Portfolio intends to limit
repurchase agreements to transactions with financial institutions having total
assets in excess of $1,000,000,000 and with broker-dealers. Securities subject
to repurchase agreements shall be limited to obligations of or guaranteed by the
U.S. Government or its agencies or by the Government of Canada or of a Province
of Canada or any instrumentality or political subdivision thereof, certificates
of deposit of banks or commercial paper which meets the criteria for other
commercial paper in which the Portfolio may invest. A Portfolio will not invest
more than 10% of its total assets in repurchase agreements which have maturities
of more than seven days and will not invest in repurchase agreements with
maturities of over 30 days. Under no circumstances will a Portfolio enter into a
repurchase agreement with The Northwestern Mutual Life Insurance Company
("Northwestern Mutual").
Each Portfolio has the right to sell securities subject to repurchase
agreements but would be required to deliver identical securities upon maturity
of the repurchase agreement unless the seller fails to pay the repurchase price.
It is each Portfolio's intention not to sell securities subject to repurchase
agreements prior to the agreement's maturity. To the extent that the proceeds
from any sale upon a default in the obligation to repurchase were less than the
repurchase price, the Portfolio would suffer a loss. The Portfolio might also
incur disposition costs in connection with liquidating its collateral and, if
bankruptcy proceedings are commenced with respect to the seller, realization
upon the collateral by the Portfolio may be delayed or
B-4
<PAGE> 24
limited and a loss may be incurred if the collateral securing the repurchase
agreement declines in value during the bankruptcy proceedings. To minimize the
possibility of losses due to the default or bankruptcy of the seller, the Fund
has adopted standards of creditworthiness for all broker-dealers with which the
Fund enters into repurchase agreements and will review compliance by such
broker-dealers periodically.
FINANCIAL FUTURES AND FORWARD CONTRACTS
Each of the Portfolios (except the Select Bond, High Yield Bond and
Money Market Portfolios) may enter into stock index futures contracts, including
indexes on specific securities, as a hedge against changes in the market values
of common stocks. The Select Bond, High Yield Bond, Balanced and International
Equity Portfolios may enter into interest rate futures contracts as a hedge
against changes in prevailing levels of interest rates. The Select Bond
Portfolio may also enter into forward sale contracts in an amount not to exceed
5% of the assets of the Portfolio. In all cases, the purpose is to establish
more definitely the effective return on securities held or intended to be
acquired by the Portfolios. The Portfolios' hedging may include sales of futures
as an offset against the effect of expected decreases in stock values or
increases in interest rates, and purchases of futures as an offset against the
effect of expected increases in stock values or decreases in interest rates.
A Portfolio will not enter into a futures contract if, as a result
thereof, (i) the aggregate market value of all open futures positions would
exceed one-third of the Portfolio's total assets or (ii) the sum of the initial
margin deposits of all open futures positions (other than an offsetting
transaction) would be more than 5% of the Portfolio's total assets. More than 5%
of the Portfolio's total assets may be committed to the aggregate of initial and
variation margin payments however. Furthermore, in order to be certain that the
Portfolio has sufficient assets to satisfy its obligations under a futures
contract, the Portfolio deposits cash or cash equivalents equal in value to the
market value of the futures contract in a segregated account for the Portfolio
with the Fund's custodian.
The following describes the stock index and interest rate futures
markets and the manner in which the Portfolios will implement the policy.
Use. The Portfolios, as identified above, may enter into stock index
futures contracts as a hedge against changes in the market values of common
stocks and may enter into interest rate futures contracts as a hedge against
changes in prevailing levels of interest rates. In both cases, the purpose is to
establish more definitely the effective return on securities held or intended to
be acquired by the Portfolios. The Portfolios' hedging may include sales of
futures as an offset against the effect of expected decreases in stock values or
increases in interest rates, and purchases of futures as an offset against the
effect of expected increases in stock values or decreases in interest rates.
The Portfolios will not enter into financial futures contracts for
speculation, and will only enter into futures contracts that are traded on
national futures exchanges and are standardized as to maturity date and
underlying securities. Currently, stock index futures contracts can be purchased
or sold with respect to the Standard and Poor's 500 Stock Index on the Chicago
Mercantile Exchange, the New York Stock Exchange Composite Index on the New York
Futures Exchange and the Value Line Stock Index on the Kansas City Board of
Trade. The principal interest rate futures exchanges in the United States are
the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York
Futures Exchange. Futures exchanges and trading are regulated under the
Commodity Exchange Act by the Commodity Futures Trading Commission.
A Portfolio will not enter into a futures contract if, as a result
thereof, (i) the aggregate market value of all open futures positions would
exceed one-third of the Portfolio's total assets or (ii) the sum of the
B-5
<PAGE> 25
initial margin deposits of all open futures positions (other than an offsetting
transaction) would be more than 5% of the Portfolio's total assets. More than 5%
of the Portfolio's total assets may be committed to the aggregate of initial and
variation margin payments however.
The Portfolios will incur brokerage commissions in connection with
transactions in futures contracts.
Description. A stock index futures contract is an agreement whereby one
party agrees to take and another party agrees to make delivery of an amount of
cash equal to a specified dollar amount times the difference between the stock
index value at the close of the last trading day of the contract and the price
at which the futures contract is originally struck. A stock index assigns
relative values to the common stocks included in the index, and the index
fluctuates with changes in the market values of the common stocks included. No
physical delivery of the underlying stocks in the index is made.
Currently, stock index futures contracts covering the stock market as a
whole and covering certain industries are being traded. It is expected that
futures contracts covering stock indexes of additional industries will
eventually be traded.
An interest rate futures contract is an agreement whereby one party
agrees to sell and another party agrees to purchase a specified amount of a
specified financial instrument (debt security) at a specified price at a
specified date, time and place. Although interest rate futures contracts
typically require actual future delivery of and payment for financial
instruments, the contracts are usually closed out before the delivery date.
A public market exists in interest rate futures contracts covering
primarily the following financial instruments: U.S. Treasury bonds; U.S.
Treasury notes; Government National Mortgage Association (GNMA) modified
pass-through mortgage-backed securities; three-month U.S. Treasury bills; 90-day
commercial paper; bank certificates of deposit; and Eurodollar certificates of
deposit. It is expected that futures contracts trading in additional financial
instruments will be authorized. The standard contract size is $100,000 for
futures contracts in U.S. Treasury bonds, U.S. Treasury notes and GNMA
pass-through securities and $1,000,000 for the other designated contracts.
It is each Portfolio's policy to close out open futures contracts
before delivery. Closing out an open futures contract sale or purchase is
effected by entering into an offsetting futures contract purchase or sale,
respectively, for the same aggregate amount of the stock index or the financial
instrument and the same delivery date. If the offsetting purchase price is less
than the original sale price, the Portfolio realizes a gain, and if it is more,
the Portfolio realizes a loss. Conversely, if the offsetting sale price is more
than the original purchase price, the Portfolio realizes a gain, and if it is
less, the Portfolio realizes a loss. The transaction costs must also be included
in these calculations. There can be no assurance, however, that the Portfolio
will be able to enter into an offsetting transaction with respect to a
particular contract at a particular time. If the Portfolio is not able to enter
into an offsetting transaction, the Portfolio will continue to be required to
maintain the margin deposits on the contract.
As an example of an offsetting transaction, the contractual obligations
arising from the sale of one contract of September Treasury Bills on an exchange
may be fulfilled at any time before delivery of the contract is required (i.e.,
on a specified date in September, the "delivery month") by the purchase of one
contract of September Treasury Bills on the same exchange. In such instance the
difference between the price at which the futures contract was sold and the
price paid for the offsetting purchase, after allowance for transaction costs,
represents the profit or loss to the Portfolio.
B-6
<PAGE> 26
Persons who trade in futures contracts may be broadly classified as
"hedgers" and "speculators." Hedgers, such as the Portfolios, whose business
activity involves investment or other commitment in equity and debt securities
or other obligations, use the financial futures markets primarily to offset
unfavorable changes in value that may occur because of fluctuations in the value
of the securities or obligations held or expected to be acquired by them.
The speculator, like the hedger, generally expects neither to deliver
nor to receive the security underlying the futures contract, but unlike the
hedger, hopes to profit from fluctuations in prevailing stock market values or
interest rates.
Each Portfolio's futures transactions will be entered into for
traditional hedging purposes--that is, futures contracts will be sold to protect
against a decline in the price of securities that the Portfolio owns, or futures
contracts will be purchased to protect the Portfolio against an increase in the
price of securities it intends to purchase. As evidence of this hedging intent,
each Portfolio expects that approximately 75% of such futures contract purchases
will be "completed"; that is, upon sale (offsetting) of these long contracts,
equivalent amounts of related securities will have been or are then being
purchased by the Portfolio in the cash market.
Margin. Initial margin is the amount of funds that must be deposited by
a Portfolio with its broker in order to initiate futures trading. An initial
margin deposit is intended to assure the Portfolio's performance of the futures
contract. The margin required for a particular futures contract is set by the
exchange on which the contract is traded and may range upward from less than 5%
of the value of the contract being traded.
Variation margin is the amount of subsequent payments that must be made
to and from the broker to maintain the Portfolio's open position in the futures
contracts. Variation margin payments are made on a daily basis as the price of
the underlying stock index or financial instrument fluctuates. If the value of
the open futures position changes (by increase, in the case of a sale, or by
decrease, in the case of a purchase) so that the loss on the futures contract
reaches a point at which the margin on deposit does not satisfy margin
requirements, the broker will require the Portfolio to make a variation margin
payment in the amount of the insufficiency. However, if the value of a position
increases because of favorable price changes in the futures contract so that the
margin deposit exceeds the required margin, the Portfolio will promptly demand
payment by the broker of variation margin in the amount of the excess. All
variation margin payments received by the Portfolio will be held by the Fund's
custodian in a separate account for the Portfolio.
In computing net asset value daily each Portfolio will mark to market
the current value of its open futures contracts. Each Portfolio expects to earn
interest income on its initial margin deposits.
Example of Purchase of Stock Index Futures Contract. A Portfolio might
purchase a stock index futures contract when it anticipates a significant market
or market sector advance and wishes to participate in such advance at a time
when the Portfolio is not fully invested, for example, because the Portfolio has
not selected the individual stocks which it wishes to purchase. The Portfolio
would be endeavoring to eliminate the effect of all or part of an expected
increase in the market price of the stocks that the Portfolio may purchase at a
later date.
For example, assume that the prices of certain stocks that the
Portfolio may later purchase tend to move in concert with the Standard and
Poor's 500 Stock Index. The Portfolio wishes to attempt to fix the purchase
price of its anticipated stock investment until the time (three months in this
example) when it may purchase the stock. Assume the stock has a market price of
125 and the Portfolio believes that, because of an anticipated advance in the
B-7
<PAGE> 27
stock market, the price will have risen in three months. The Portfolio might
enter into futures contract purchases of the Standard and Poor's 500 Stock Index
for a price of 125. If the market price of the stock should increase from 125 to
130, the futures market price for the Standard and Poor's 500 Stock Index might
also increase, e.g., from 125 to 130. In that case, the five-point increase in
the price that the Portfolio would have to pay for the stock would be offset by
the five-point gain realized by closing out the futures contract purchase.
If the Portfolio should be mistaken in its forecast of market values,
and the stock index should decline below 125, the market value of the stocks
being hedged would presumably decline. Unless the Portfolio would purchase the
stocks for the decreased price, the Portfolio would realize a loss on the sale
of the futures contract which would not be offset by the price decrease.
Example of Sale of Stock Index Futures Contract. The Portfolio might
sell stock index futures contracts in anticipation of a general market or market
sector decline that may adversely affect the market values of the stocks held by
the Portfolio. The Portfolio would be endeavoring to substantially reduce the
risk of a decline in the value of its stocks without selling the stocks with
resultant transaction costs.
For example, assume that the market price of certain stocks held by the
Portfolio tend to move in concert with the Standard and Poor's 500 Stock Index.
The stock currently has a market value of 125, which the Portfolio believes will
decline because of an anticipated decline in the stock market. The Portfolio
wishes to attempt to fix the current market value of the stock until some time
in the future. The Portfolio might enter into a futures contract sale of the
Standard and Poor's 500 Stock Index at a price of 125. If the market price of
the stock should decline from 125 to 120, the futures market price of the
Standard and Poor's 500 Stock Index might also decline, e.g. from 125 to 120. In
that case the five-point loss in the market value of the stock would be offset
by the five-point gain realized by closing out the futures contract. The futures
market price of the Standard and Poor's 500 Stock Index might decline to more or
less than 120 because of the imperfect correlation with the prices of the stocks
hedged.
If the Portfolio should be mistaken in its forecast of the stock
market, and the futures market price of the Standard and Poor's 500 Stock Index
should increase above 125, the market price of the stock would increase. The
benefit of this increase would be offset by the loss realized on closing out the
futures contract sale.
Example of Purchase of Interest Rate Futures Contract. The Portfolio
might purchase an interest rate futures contract when it wishes to defer for a
time a fully invested position in longer term securities, for example, in order
to continue holding shorter term securities with higher yields. The Portfolio
would be endeavoring to eliminate the effect of all or part of an expected
increase in market price of the longer term bonds that the Portfolio may wish to
purchase at a later date.
For example, assume that the market price of a type of longer term
bonds that the Portfolio may later purchase, currently yielding 10%, tends to
move in concert with futures market prices of long-term U.S. Treasury bonds. The
Portfolio wishes to attempt to fix the purchase price (and thus the 10% yield)
of its anticipated longer term bond investment until the time (four months away
in this example) when it may purchase the bond. Assume the longer term bond has
a market price of 100, and the Portfolio believes that, because of an
anticipated decline in interest rates, the price will have risen (and
correspondingly the yield will have declined) in four months. The Portfolio
might enter into futures contract purchases of Treasury bonds for a price of 98.
At the same time, the Portfolio would purchase, for example at 100, or continue
to hold, shorter term securities that are either maturing in four months or are
earmarked by the Portfolio for sale in four months. Assume these short-term
securities are yielding 15%. If the market price of the longer term bond should
increase from 100 to 105, the futures market price for
B-8
<PAGE> 28
Treasury bonds might also increase, e.g., from 98 to 103. In that case, the
five-point increase in the price that the Portfolio would have to pay for the
longer term bond would be offset by the five-point gain realized by closing out
the futures contract purchase.
If the Portfolio should be mistaken in its forecast of interest rates,
and the futures market price of the U.S. Treasury obligation should decline
below 98, the market price of the security being hedged would presumably
decline. If short-term rates at the same time fall to 10% or below, it is likely
that the Portfolio would follow through with its anticipated purchases of longer
term bonds, as the market price of available longer term bonds would have
decreased. The benefit of this price decrease, and thus the yield increase,
would be offset by the loss realized on closing out the futures contract
purchase.
Example of Sale of Interest Rate Futures Contract. The Portfolio might
sell an interest rate futures contract in order to maintain the income derived
from its continued holding of a long-term security while endeavoring to avoid
part or all of the loss in market value that would otherwise accompany a decline
in prices of longer term securities because of an increase in prevailing
interest rates.
For example, assume that the market price of a certain longer term
security held by the Portfolio tends to move in concert with the futures market
prices of long-term U.S. Treasury bonds. The security has a current market price
of 100, which the Portfolio believes will decline because of an anticipated rise
in interest rates. The Portfolio wishes to attempt to fix the current market
value of this security until some point in the future. The Portfolio might enter
into a futures contract sale of Treasury bonds at a price of 98. If the market
value of the security should decline from 100 to 95, the futures market price of
Treasury bonds might also decline, e.g., from 98 to 93. In that case, the
five-point loss in the market value of the security would be offset by the
five-point gain realized by closing out the futures contract sale. The futures
market price of Treasury bonds might decline to more or less than 93 because of
the imperfect correlation with the prices of the securities hedged.
If the Portfolio should be mistaken in its forecast of interest rates,
and the futures market price of the U.S. Treasury obligation should increase
above 98, the market price of the securities, including the security being
hedged, would increase. The benefit of this increase would be offset by the loss
realized on closing out the futures contract sale.
Risks. Financial futures prices are volatile and difficult to forecast.
Stock index futures prices reflect the market values of the stocks included in
the index, while interest rate futures contracts are influenced, among other
things, by changes in prevailing interest rates and anticipation of future
interest rate changes. The factors influencing interest rate futures prices are
in turn affected by government fiscal and monetary policies and actions, and
national and international political and economic events, while stock market
values are also influenced by corporate management policies, consumer demand,
competition, sources of raw materials and supplies and government regulation.
At best, the correlation between changes in prices of futures contracts
and the securities being hedged can be only approximate. The degree of
imperfection of correlation depends upon circumstances, such as: variations in
speculative market demand for futures and for equity or debt securities,
including technical influences in futures trading, and differences between the
securities being hedged and the instruments underlying the standard futures
contracts available for trading. A decision of whether, when and how to hedge
involves the exercise of skill and judgment, and even a well-conceived hedge may
be unsuccessful to some degree because of market behavior or unexpected stock
market or interest rate trends.
B-9
<PAGE> 29
Because of the low margin deposits required, futures trading involves
an extremely high degree of leverage. As a result, a relatively small price
movement in a futures contract may result in immediate and substantial loss, as
well as gain, to the investor. For example, if at the time of purchase, 10% of
the value of the futures contract is deposited as initial margin, a 10% decrease
in the value of the futures contract would result in a total loss of the initial
margin deposit before any deduction for the transaction costs, if the account
were then closed out, and 15% decrease would result in a loss equal to 150% of
the initial margin deposit. Thus, a purchase or sale of a futures contract may
result in losses in excess of the amount invested in the futures contract.
However, the Portfolio would presumably have sustained comparable losses if,
instead of the futures contract, it had invested in the underlying security.
Furthermore, in order to be certain that the Portfolio has sufficient assets to
satisfy its obligations when it purchases a futures contract, the Portfolio
deposits cash or cash equivalents equal in value to the market value of the
futures contract in a segregated account for the Portfolio with the Fund's
custodian.
Most United States interest rate futures exchanges and the Chicago
Mercantile Exchange limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond that limit. The daily limit governs only
price movement during a particular trading day and therefore does not limit
potential losses because the limit may prevent the liquidation of unfavorable
positions. Futures contract prices have occasionally moved to the daily limit
for several consecutive trading days with little or no trading, thereby
preventing prompt liquidation of futures positions and subjecting some futures
traders to substantial losses.
Foreign Currency Futures. The International Equity and High Yield Bond
Portfolios have the authority to deal in forward foreign exchange between
currencies of the different countries in which the Portfolio will invest as a
hedge against possible variations in the foreign exchange rate between these
currencies. This is accomplished through contractual agreements to purchase or
sell a specified currency at a specified future date and price set at the time
of the contract. The Portfolios' dealings in forward foreign exchange will be
limited to hedging involving either specific transactions or portfolio
positions. Transaction hedging is the purchase or sale of forward foreign
currency with respect to specific receivables or payables of the Portfolio
arising from the purchase and sale of portfolio securities, the sale and
redemption of shares of the Portfolio, or the payment of dividends and
distributions by the Portfolio. Position hedging is the sale of forward foreign
currency with respect to portfolio security positions denominated or quoted in
such foreign currency. The International Equity and High Yield Bond Portfolios
will not speculate in forward foreign exchange.
Risks. Financial futures prices are volatile and difficult to forecast.

for several consecutive trading days with little or no trading, thereby

traders to substantial losses.
Federal Income Tax Treatment. For Federal income tax purposes, each
Portfolio is required to recognize as income for each taxable year its net
unrealized gains and losses on futures contracts as of the end of the year as
well as those actually realized during the year. Any gain or loss recognized
with respect to a futures contract is considered to be 60% long-term and 40%
short-term, without regard to the holding period of the contract. In the case of
a futures transaction classified as a "mixed straddle," the recognition of
losses may be deferred to a later taxable year.
In order for each Portfolio to continue to qualify for Federal income
tax treatment as a regulated investment company, at least 90% of its gross
income for a taxable year must be derived from qualifying income, i.e.,
dividends, interest, income derived from loans of securities, and gains from the
sale of securities. Any net gain realized from the closing out of futures
contracts, for purposes of the 90% requirement, is considered gain from the sale
of securities and therefore is qualifying income. In addition, gains realized on
the sale or other disposition of securities held for less than three months must
be limited to less than 30% of the Portfolio's annual gross income.
Consequently, in order for the Portfolio to avoid realizing a gain within a
three-month period, the Portfolio may be required to defer the closing out of a
contract beyond the time when it would otherwise be advantageous to do so.
COVERED CALL OPTION CONTRACTS
The Index 500 Stock, Index 400 Stock, Balanced, Growth and Income
Stock, Growth Stock, Small Cap Growth Stock, Aggressive Growth Stock and High
Yield Bond Portfolios may engage in writing covered call option
contracts--options on securities owned by the Portfolios--and may purchase call
options only to
B-11
<PAGE> 31
close out a position acquired through the writing of such options. Any option
written or purchased by a Portfolio must be listed on a domestic exchange. A
covered call option gives the purchaser of the option the right to purchase the
underlying security at a fixed exercise price at any time prior to the
expiration of the option, regardless of the market price of the security during
the option period. As consideration for the option the purchaser pays the
Portfolio a premium which the Portfolio retains whether or not the option is
exercised. A covered call option will benefit a Portfolio if, over the option
period, the underlying security declines in value or does not appreciate above
the aggregate value of the exercise price and the premium. However, a Portfolio
risks a loss of profits if the underlying security appreciates above the
aggregate value of the exercise price and the premium.
The Portfolios may also close out a position acquired through writing a
call option by purchasing a call option on the same security with the same
exercise price and expiration date as the call option which it has previously
written on the security. Thus, when a security subject to a call option is sold
from a Portfolio (i.e., to protect the Portfolio from possible depreciation of
the security), the Portfolio will purchase a call option on the security to
close out the existing call option. Depending on the premium of the contract, a
Portfolio will realize a profit or a loss on the transaction. Option
transactions may increase a Portfolio's transaction costs and turnover rate and
will be initiated only where appropriate to achieve a Portfolio's investment
objectives.
REVERSE REPURCHASE AGREEMENTS
The Money Market and Balanced Portfolios may enter into reverse
repurchase agreements with banks and broker-dealers. Such agreements involve the
sale of money market securities held by a Portfolio pursuant to an agreement to
repurchase the securities at an agreed upon price, date and interest payment.
The Portfolio will use the proceeds of reverse repurchase agreements to purchase
other money market securities which either mature, or can be sold under an
agreement to resell, at or prior to the expiration of the reverse repurchase
agreement. A Portfolio will utilize reverse repurchase agreements when the
interest income to be earned from the investment of proceeds from the
transaction is greater than the interest expense of the reverse repurchase
transaction. When effecting reverse repurchase transactions, a Portfolio will
hold securities of a dollar amount equal in value to the securities subject to
the reverse repurchase agreement in a segregated account. Amounts subject to
reverse repurchase agreements are also subject to a 300% asset coverage
requirement. If such amounts in the aggregate exceed this asset coverage
requirement, the Portfolio would be obligated within three days to reduce such
amounts to meet the requirement. Under no circumstances will a Portfolio enter
into a reverse repurchase agreement with Northwestern Mutual.
WARRANTS
The Index 500 Stock, Index 400 Stock, Balanced, Growth and Income
Stock, Growth Stock, Small Cap Growth Stock, Aggressive Growth Stock and High
Yield Bond Portfolios may invest in warrants. No Portfolio intends to invest
more than 2% of its net assets in warrants that are not listed on a national
securities exchange. In no event will a Portfolio's investment in warrants
exceed 5% of its net assets. (A warrant is a right to buy a certain security at
a set price during a certain time period.)
ASSET-BACKED AND VARIABLE RATE SECURITIES
Consistent with its investment objectives and policies, the Money
Market Portfolio may invest in asset-backed and variable rate securities.
Asset-backed securities represent fractional interests in pools of
retail installment loans or revolving credit receivables. These assets are
generally held by a special purpose trust and payments of principal and
interest, or interest only, are passed through or paid through monthly or
B-12
<PAGE> 32
quarterly to certificate holders. Payments may be guaranteed up to certain
amounts by letters of credit issued by a financial institution affiliated or
unaffiliated with the trustee or originator of the trust. Underlying receivables
are generally subject to prepayment, which may reduce the overall return to
certificate holders. Nevertheless, for asset-backed securities, principal
repayment rates tend not to vary much with interest rates and the short-term
nature of the underlying loans or other receivables tends to dampen the impact
of any change in the prepayment level. Certificate holders may also experience
delays in payment on the certificates if the full amounts due on underlying
sales contracts or other receivables are not realized by the trust because of
unanticipated legal or administrative costs of enforcing the contracts, or
because of depreciation or damage to the collateral securing certain contracts,
or other factors.
Variable rate securities bear rates of interest that are adjusted
periodically or which "float" continuously according to formulae intended to
minimize fluctuations in values of the instruments. For the Money Market
Portfolio, the Fund determines the maturity of variable rate securities in
accordance with Securities and Exchange Commission rules that allow the Fund to
consider certain of such instruments as having maturities less than the maturity
date on the instrument.
SHORT-TERM TRADING
Each Portfolio will generally not engage in short-term trading
(purchases and sales within seven days).
FIRM COMMITMENT AGREEMENTS AND "WHEN-ISSUED" SECURITIES
Each Portfolio may enter into firm commitment agreements for the
purchase of securities at an agreed upon price on a specified future date. A
Portfolio may purchase new issues of securities on a "when-issued" basis,
whereby the payment obligation and interest rate on the instruments are fixed at
the time of the transaction. Such transactions might be entered into, for
example, when the manager of a Portfolio anticipates a decline in the yield of
securities of a given issuer and is able to obtain a more advantageous yield by
committing currently to purchase securities to be issued or delivered later.
A Portfolio will not enter into such a transaction for the purpose of
investment leverage. Liability for the purchase price - and all the rights and
risks of ownership of the securities - accrue to the Portfolio at the time it
becomes obligated to purchase such securities, although delivery and payment
occur at a later date. Accordingly, if the market price of the security should
decline, the effect of the agreement would be to obligate the Portfolio to
purchase the security at a price above the current market price on the date of
delivery and payment. During the time the Portfolio is obligated to purchase
such securities it will maintain in a segregated account U.S. Government
securities, high-grade debt obligations, or cash or cash equivalents of an
aggregate current value sufficient to make payment for the securities.
EURODOLLAR CERTIFICATES OF DEPOSIT
The Money Market, Balanced, Growth and Income Stock, Growth Stock and
High Yield Bond Portfolios may purchase Eurodollar certificates of deposit
issued by foreign branches of U.S. banks, but consideration will be given to
their marketability and possible restrictions on the flow of international
currency transactions. Investment in such securities involves considerations
which are not ordinarily associated with investing in domestic instruments,
including currency exchange control regulations, the possibility of
expropriation, seizure, or nationalization of foreign deposits, less liquidity
and increased volatility in foreign securities markets, and the impact of
political, social or diplomatic developments or the adoption of other foreign
government restrictions that might adversely affect the payment of principal
B-13
<PAGE> 33
and interest. If the Fund were to invoke legal processes, it might encounter
greater difficulties abroad than in the United States.
PRIVATE PLACEMENT TRANSACTIONS AND ILLIQUID ASSETS
Each Portfolio may invest up to 15% of its total assets in securities
acquired in private placement transactions and other illiquid assets. For the
Money Market Portfolio the limit is 10%. For the purpose of determining each
Portfolio's net asset value, these assets will be valued at their fair value as
determined in good faith by the Fund's Directors. If a Portfolio should have
occasion to sell an investment in restricted securities at a time when the
market for such investments is unfavorable, a considerable period may elapse
between the time when the decision to sell it is made and the time when the
Portfolio will be able to sell the investment, with a possible adverse effect
upon the amount to be realized from the sale.
Notwithstanding these limitations a Portfolio may purchase securities
which, though not registered under the Securities Act of 1933 (the "1933 Act"),
are eligible for purchase and sale pursuant to Rule 144A under the 1933 Act.
Rule 144A permits unregistered securities to be traded among qualified
institutional investors, including the Portfolios. Rule 144A securities that are
determined to be liquid are not subject to the limitations on illiquid assets.
The Fund's investment adviser, Northwestern Mutual Investment Services, LLC,
determines and monitors the liquidity status of each Rule 144A security in which
a Portfolio invests, subject to supervision and oversight by the Board of
Directors of the Fund. The investment adviser takes into account all of the
factors which may have a material bearing on the ability of the Portfolio to
dispose of the security in seven days or less, at a price reasonably consistent
with the value used to determine the Portfolio's net asset value per share,
including the following factors: (1) the frequency and volume of trades, (2) the
number and sources of price quotes, (3) the number, and identity, of dealers
willing to purchase or sell the issue, and the number and identity of other
potential purchasers, (4) any dealer undertakings to make a market in the
security, (5) the nature of the security, and (6) the nature of the market in
which the issue is traded, including the time typically required to make trades,
the methods of soliciting offers and the mechanics of transfer.
RISK FACTORS FOR FOREIGN SECURITIES, FOREIGN CURRENCIES AND FOREIGN INTEREST
RATES
Foreign Securities The International Equity Portfolio has an unlimited
right to purchase securities in any foreign country, developed or developing, if
they are listed on a stock exchange, as well as a limited right to purchase such
securities if they are unlisted. The Growth and Income Portfolio, Select Bond
Portfolio, Balanced Portfolio and High Yield Bond Portfolio may each invest a
portion of their assets in foreign securities. Investors should consider
carefully the substantial risks involved in securities of companies and
governments of foreign nations, which are in addition to the usual risks
inherent in domestic investments.
There may be less publicly available information about foreign
companies comparable to the reports and ratings published about companies in the
U.S. Foreign companies are not generally subject to uniform accounting or
financial reporting standards, and auditing practices and requirements may not
be comparable to those applicable to U.S. companies. The Portfolios, therefore,
may encounter difficulty in obtaining market quotations for purposes of valuing
their assets and calculating their net asset value. Foreign markets have
substantially less volume than the New York Stock Exchange and securities of
some foreign companies are less liquid and more volatile than securities of
comparable U.S. companies. Although the International Equity Portfolio may
invest up to 15% of its total assets in unlisted foreign securities, including
up to 10% of its total assets in securities with a limited trading market, in
the opinion of management such securities with a limited trading market
generally do not present a significant liquidity problem. Commission rates in
foreign countries, which are generally fixed rather than subject to
B-14
<PAGE> 34
negotiation as in the U.S., are likely to be higher. In many foreign countries
there is less government supervision and regulation of stock exchanges, brokers
and listed companies than in the U.S.
Emerging markets. Investments in companies domiciled in developing
countries may be subject to potentially higher risks than investments in
developed countries. These risks include (i) less social, political and economic
stability; (ii) the small current size of the markets for such securities and
the currently low or nonexistent volume of trading, which result in a lack of
liquidity and in greater price volatility; (iii) certain national policies which
may restrict each Portfolio's investment opportunities, including restrictions
on investment in issuers or industries deemed sensitive to national interests;
(iv) foreign taxation; (v) the absence of developed legal structures governing
private or foreign investment or allowing for judicial redress for injury to
private property; (vi) the absence, until recently in many developing countries,
of a capital market structure or market-oriented economy; and (vii) the
possibility that recent favorable economic developments in some developing
countries may be slowed or reversed by unanticipated political or social events
in such countries.
In addition, many countries in which the Portfolios may invest have
experienced substantial, and in some periods extremely high, rates of inflation
for many years. Inflation and rapid fluctuations in inflation rates have had and
may continue to have negative effects on the economies and securities markets of
certain countries. Moreover, the economies of some developing countries may
differ favorably or unfavorably from the U.S. economy in such respects as growth
of gross domestic product, rate of inflation, currency depreciation, capital
reinvestment, resource self-sufficiency and balance of payments position.
Investments in developing countries may involve risks of
nationalization, expropriation and confiscatory taxation. For example, the
Communist governments of a number of Eastern European countries expropriated
large amounts of private property in the past, in many cases without adequate
compensation, and there can be no assurance that such expropriation will not
occur in the future. In the event of expropriation, each Portfolio could lose a
substantial portion of any investments it has made in the affected countries.
Further, no accounting standards exist in certain developing countries. Finally,
even though the currencies of some developing countries, such as certain Eastern
European countries, may be convertible into U.S. dollars, the conversion rates
may be artificial to the actual market values and may be adverse to the
shareholders of a Portfolio.
Russian securities. Investing in Russian companies involves a high
degree of risk and special considerations not typically associated with
investing in the U.S. securities markets, and should be considered highly
speculative. Such risks include, together with Russia's continuing political and
economic instability and the slow-paced development of its market economy, the
following: (a) delays in settling portfolio transactions and risk of loss
arising out of Russia's system of share registration and custody; (b) the risk
that it may be impossible or more difficult than in other countries to obtain
and/or enforce a judgment; (c) pervasiveness of corruption, insider-trading, and
crime in the Russian economic system; (d) currency exchange rate volatility and
the lack of available currency hedging instruments; (e) higher rates of
inflation (including the risk of social unrest associated with periods of
hyper-inflation); (f) controls on foreign investment and local practices
disfavoring foreign investors and limitations on repatriation of invested
capital, profits and dividends, and on a Portfolio's ability to exchange local
currencies for U.S. dollars; (g) the risk that the government of Russia or other
executive or legislative bodies may decide not to continue to support the
economic reform programs implemented since the dissolution of the Soviet Union
and could follow radically different political and/or economic policies to the
detriment of investors, including non-market-oriented policies such as the
support of certain industries at the expense of other sectors or investors, a
return to the centrally planned economy that existed prior to the dissolution of
the Soviet Union, or the nationalization of
B-15
<PAGE> 35
privatized enterprises; (h) the risks of investing in securities with
substantially less liquidity and in issuers having significantly smaller market
capitalizations, when compared to securities and issuers in more developed
markets; (i) the difficulties associated in obtaining accurate market valuations
of many Russian securities, based partly on the limited amount of publicly
available information; (j) the financial condition of Russian companies,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (k) dependency on exports and the corresponding importance
of international trade; (l) the risk that the Russian tax system will not be
reformed to prevent inconsistent, retroactive and/or exorbitant taxation or, in
the alternative, the risk that a reformed tax system may result in the
inconsistent and unpredictable enforcement of the new tax laws; (m) possible
difficulty in identifying a purchaser of securities held by the Portfolios due
to the underdeveloped nature of the securities markets; (n) the possibility that
pending legislation could restrict the levels of foreign investment in certain
industries, thereby limiting the number of investment opportunities in Russia;
(o) the risk that pending legislation would confer to Russian courts the
exclusive jurisdiction to resolve disputes between foreign investors and the
Russian government, instead of bringing such disputes before an
internationally-accepted third-country arbitrator; and (p) the difficulty in
obtaining information about the financial condition of Russian issuers, in light
of the different disclosure and accounting standards applicable to Russian
companies.
There is little long-term historical data on Russian securities markets
because they are relatively new and a substantial proportion of securities
transactions in Russia are privately negotiated outside of stock exchanges.
Because of the recent formation of the securities markets as well as the
underdeveloped state of the banking and telecommunications systems, settlement,
clearing and registration of securities transactions are subject to significant
risks. Ownership of shares (except where shares are held through depositories
that meet the requirements of the 1940 Act) is defined according to entries in
the company's share register and normally evidenced by extracts from the
register or by formal share certificates. However, there is no central
registration system for shareholders and these services are carried out by the
companies themselves or by registrars located throughout Russia. These
registrars are not necessarily subject to effective state supervision nor are
they licensed with any governmental entity and it is possible for the Portfolios
to lose their registration through fraud, negligence or even mere oversight.
While each Portfolio will endeavor to ensure that its interest continues to be
appropriately recorded either itself or through a custodian or other agent
inspecting the share register and by obtaining extracts of share registers
through regular confirmations, these extracts have no legal enforceability and
it is possible that subsequent illegal amendment or other fraudulent act may
deprive the Portfolios of their ownership rights or improperly dilute their
interests. In addition, while applicable Russian regulations impose liability on
registrars for losses resulting from their errors, it may be difficult for the
Portfolios to enforce any rights they may have against the registrar or issuer
of the securities in the event of loss of share registration. Furthermore,
although a Russian public enterprise with more than 500 shareholders is required
by law to contract out the maintenance of its shareholder register to an
independent entity that meets certain criteria, in practice this regulation has
not always been strictly enforced. Because of this lack of independence,
management of a company may be able to exert considerable influence over who can
purchase and sell the company's shares by illegally instructing the registrar to
refuse to record transactions in the share register. In addition, so-called
"financial-industrial groups" have emerged in recent years that seek to deter
outside investors from interfering in the management of companies they control.
These practices may prevent the Portfolios from investing in the securities of
certain Russian companies deemed suitable by the manager. Further, this also
could cause a delay in the sale of Russian company securities by a Portfolio if
a potential purchaser is deemed unsuitable, which may expose the Portfolio to
potential loss on the investment.
B-16
<PAGE> 36
Currency Each Portfolio's management endeavors to buy and sell foreign
currencies on as favorable a basis as practicable. Some price spread in currency
exchange (to cover service charges) will be incurred, particularly when a
Portfolio changes investments from one country to another or when proceeds of
the sale of shares in U.S. dollars are used for purchase of securities in
foreign countries. Also, some countries may adopt policies which would prevent
the Portfolios from transferring cash out of the country or withhold portions of
interest and dividends at the source. There is the possibility of cessation of
trading on national exchanges, expropriation, nationalization or confiscatory
taxation, withholding and other foreign taxes on income or other amounts,
foreign exchange controls (which may include suspension of the ability to
transfer currency from a given country), default in foreign government
securities, political or social instability, or diplomatic developments which
could affect investments in securities of issuers in foreign nations.
Each Portfolio may be affected either unfavorably or favorably by
fluctuations in the relative rates of exchange between the currencies of
different nations, by exchange control regulations and by indigenous economic
and political developments. Some countries in which the Portfolios may invest
may also have fixed or managed currencies that are not free-floating against the
U.S. dollar. Further, certain currencies may not be internationally traded.
Certain of these currencies have experienced a steady devaluation
relative to the U.S. dollar. Any devaluations in the currencies in which a
Portfolio's securities are denominated may have a detrimental impact on that
Portfolio. Through the flexible policy of the Portfolio, its manager endeavors
to avoid unfavorable consequences and to take advantage of favorable
developments in particular nations where from time to time it places the
investments of the International Equity Portfolio.
The exercise of this flexible policy may include decisions to buy
securities with substantial risk characteristics and other decisions such as
changing the emphasis on investments from one nation to another and from one
type of security to another. Some of these decisions may later prove profitable
and others may not. No assurance can be given that profits, if any, will exceed
losses.
Euro. On January 1, 1999, the European Monetary Union (EMU) introduced
a new single currency, the euro, which is replacing the national currency for
participating member countries. The transition and the elimination of currency
risk among EMU countries may change the economic environment and behavior of
investors, particularly in European markets.
Franklin Resources, Inc. has created an interdepartmental team to
handle all euro-related changes to enable the mutual funds managed by Templeton
Investment Counsel, Inc. to process transactions accurately and completely with
minimal disruption to business activities. While the implementation of the euro
could have a negative effect on the International Equity Portfolio, the
Portfolio's manager and its affiliated services providers are taking steps they
believe are reasonably designed to address the euro issue.
Interest rate To the extent each Portfolio invests in debt securities,
changes in interest rates in any country where the Portfolio is invested will
affect the value of its assets and, consequently, its share price. Rising
interest rates, which often occur during times of inflation or a growing
economy, are likely to cause the face value of a debt security to decrease,
having a negative effect on the value of the Portfolio's shares. Of course,
interest rates have increased and decreased, sometimes very dramatically, in the
past. These changes are likely to occur again in the future at unpredictable
times.

PORTFOLIO TURNOVER
Portfolio turnover may vary from year to year or within a year
depending upon economic, market and business conditions. The annual portfolio
turnover rates of the Portfolios cannot be accurately predicted. It is
anticipated that the annual portfolio turnover rate for the Index 500 Stock
Portfolio will not exceed 6%, that the rate for the High Yield Bond Portfolio
will generally not exceed 200% and that the rate for the Select Bond Portfolio
will generally not exceed 185%. For the other Portfolios, it is anticipated that
the rate will generally not exceed 100%. In 1999 the portfolio turnover rate for
the Growth and Income Stock Portfolio exceeded 100% because of market conditions
over the course of the year. Short-term debt securities are excluded in the
calculation of portfolio turnover rates. U.S. Government securities are included
in the calculation of portfolio turnover rates.
For years 1998 and 1999, the portfolio turnover rates were:

INVESTMENT ADVISORY AND OTHER SERVICES
The Fund's investment adviser, Northwestern Mutual Investment Services,
LLC ("NMIS"), is a wholly-owned subsidiary of Northwestern Mutual. The adviser
provides investment advice and recommendations regarding the purchase and sale
of securities for the Portfolios and the selection of brokers pursuant to
Investment Advisory Agreements (the "Agreements"). Each Agreement provides that
the adviser will also provide certain services and pay the expenses of the Fund
for certain other administrative services, office space and facilities and the
services of all directors, officers and employees of the Fund. Each Portfolio
(except the Select Bond, Money Market and Balanced Portfolios) pays its own
expenses for fees for services rendered by the custodian, legal counsel and
auditors; costs of Federal registrations of Fund shares; expenses of meetings
and reports; taxes; and brokerage and other expenses directly related to
portfolio transactions.
For acting as investment adviser and for providing such services and
paying such expenses the adviser is paid a monthly fee at the annual rates set
forth in the prospectus for the respective Portfolios. The Fund also pays all
interest charges, brokerage commissions, taxes and extraordinary expenses
incurred in connection with the operation of the Fund. Expenses paid by the Fund
are charged to the Portfolios to which the expenses relate.
For the fiscal years ended December 31, 1997, December 31, 1998,
December 31 1999, NMIS received $23,423,272, $28,213,362, and $32,898,876,
respectively, for its services as investment adviser to the Fund.
Northwestern Mutual and its wholly-owned subsidiary, Northwestern
Investment Management Company, employ a full staff of investment personnel to
manage the investment assets of Northwestern Mutual. These personnel and
B-23
<PAGE> 43
related facilities are utilized by NMIS in performing its obligations under the
Agreements and Northwestern Mutual is a party to each Agreement.
"Northwestern Mutual Life" is the name and service mark of The
Northwestern Mutual Life Insurance Company and the right of the Fund to use the
name and mark is subject to the consent of Northwestern Mutual. Under the
Agreement providing such consent, the Fund recognizes the prior rights of
Northwestern Mutual in the name and mark, agrees that use of the name and mark
by the Fund will inure to the benefit of Northwestern Mutual and agrees that its
right to use the name and mark can be terminated by Northwestern Mutual and will
automatically be terminated if at any time NMIS ceases to be the investment
adviser to the Fund or if NMIS ceases to be a subsidiary of Northwestern Mutual.
Templeton Investment Counsel, Inc. ("Templeton Counsel"), a Florida
corporation with principal offices at 500 East Broward Boulevard, Ft.
Lauderdale, Florida 33394 has been retained under an investment sub-advisory
agreement to provide investment advice and, in general, to conduct the
management investment program of the International Equity Portfolio, subject to
the general control of the Board of Directors of the Fund. Templeton Counsel is
a wholly-owned indirect subsidiary of Franklin Resources, Inc. Certain clients
of Templeton Counsel may have investment objectives and policies similar to
those of the International Equity Portfolio. Templeton Counsel may, from time to
time, make recommendations which result in the purchase or sale of a particular
security by its other clients simultaneously with the International Equity
Portfolio. If transactions on behalf of more than one client during the same
period increase the demand for securities being purchased or the supply of
securities being sold, there may be an adverse effect on price. It is the policy
of Templeton Counsel to allocate advisory recommendations and the placing of
orders in a manner which is deemed equitable by Templeton Counsel to the
accounts involved, including the International Equity Portfolio. When two or
more of the clients of Templeton Counsel (including the International Equity
Portfolio) are purchasing the same security on a given day from the same
broker-dealer, such transactions may be averaged as to price. For its services
pursuant to the sub-advisory agreement, Templeton Counsel is paid, by NMIS,
compensation at the annual rate of .50% of the average net assets of the
International Equity Portfolio, reduced to .40% on assets in excess of $100
million.

PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION AND OTHER PRACTICES
There is generally no stated commission in the case of fixed-income
securities, which are traded in the over-the-counter markets, but the price paid
by the Fund usually includes an undisclosed dealer commission or mark-up.
B-25
<PAGE> 45
In underwritten offerings, the price paid by the Fund includes a disclosed,
fixed commission or discount retained by the underwriter or dealer. Transactions
on U.S. stock exchanges and other agency transactions involve the payment by the
Fund of negotiated brokerage commissions. Such commissions vary among different
brokers. Also, a particular broker may charge different commissions according to
such factors as the difficulty and size of the transaction. In the case of
securities traded on some foreign stock exchanges, brokerage commissions may be
fixed and the investment adviser or sub-adviser may be unable to negotiate
commission rates for these transactions.
The investment adviser, or sub-adviser in the case of the Growth and
Income Stock and International Equity Portfolios, places all orders for the
purchase and sale of portfolio securities, options, and futures contracts for
each Portfolio through a substantial number of brokers and dealers or futures
commission merchants. In executing transactions, the investment adviser or
sub-adviser will attempt to obtain the best net results for the Portfolio,
taking into account such factors as price (including the applicable brokerage
commission or dollar spread), size of order, the nature of the market for the
security, the timing of the transaction, the reputation, experience and
financial stability of the broker-dealer involved, the quality of the service,
the difficulty of execution and operational facilities of the firms involved,
and the firm's risk in positioning a block of securities. In transactions on
stock exchanges in the United States, payments of brokerage commissions are
negotiated. In effecting purchases and sales of portfolio securities in
transactions on United States stock exchanges for the account of the Fund, the
investment adviser or sub-adviser may pay higher commission rates than the
lowest available when the investment adviser or sub-adviser believes it is
reasonable to do so in light of the value of the brokerage and research services
provided by the broker effecting the transaction, as described below. In the
case of securities traded on some foreign stock exchanges, brokerage commissions
may be fixed and the investment adviser or sub-adviser may be unable to
negotiate commission rates for these transactions. In the case of securities
traded on the over-the-counter markets, there is generally no stated commission,
but the price includes an undisclosed commission or markup.
Some securities considered for investment by the Fund's Portfolios may
also be appropriate for other clients served by the investment adviser or
sub-adviser. If a purchase or sale of securities consistent with the investment
policies of a Portfolio and one or more of these clients served by the
investment adviser or sub-adviser is considered at or about the same time,
transactions in such securities will be allocated among the Portfolios and
clients in a manner deemed fair and reasonable by the investment adviser or
sub-adviser. Although there is no specified formula for allocating such
transactions, the various allocation methods used by the investment adviser or
sub-adviser, and the results of such allocations, are subject to periodic review
by the Fund's investment adviser and directors.
It has for many years been a common practice in the investment advisory
business for advisers of investment companies and other institutional investors
to receive research services from broker-dealers which execute portfolio
transactions for the clients of such advisers. Consistent with this practice,
the investment adviser or sub-adviser may receive research services from many
broker-dealers with which the investment adviser or sub-adviser places portfolio
transactions. These services, which in some cases may also be purchased for
cash, include such matters as general economic and security market reviews,
industry and company reviews, evaluations of securities and recommendations as
to the purchase and sale of securities. Some of these services may be of value
to the investment adviser or sub-adviser in advising its various clients
(including the Portfolios), although not all of these services are necessarily
useful and of value in managing a Portfolio.
As permitted by Section 28(e) of the Securities Exchange Act of 1934,
the investment adviser or sub-adviser may cause a Portfolio to pay a
broker-dealer, which provides "brokerage and research services" (as defined in
the Act) to the investment adviser or sub-adviser, an amount of disclosed
B-26
<PAGE> 46
commission for effecting a securities transaction for the Portfolio in excess of
the commission which another broker-dealer would have charged for effecting that
transaction.
There are no arrangements whatsoever, written or oral, relating to the
allocation to specific brokers of orders for Portfolio transactions.
Consideration is given to those firms providing statistical and research
services to the investment adviser or sub-adviser, but it is not the policy of
any Portfolio to pay higher brokerage commissions to a firm solely because it
has provided such services. In 1999 all brokerage business was allocated to
firms which provided these services. Statistical and research services furnished
by brokers typically include: analysts' reports on companies and industries,
market forecasts, economic analyses and the like. Such services may tend to
reduce the expenses of the adviser or sub-adviser and this has been considered
in setting the advisory fee paid by each Portfolio. During the years ended
December 31, 1997, 1998, and 1999, the Fund paid brokerage commissions of
$3,985,791, $5,133,812, and $6,299,124, respectively.
The Directors of the Fund have recently authorized the investment
adviser and sub-advisers to place portfolio orders for the Fund with Robert W.
Baird & Co. Incorporated ("Baird"), a broker-dealer which is a corporate
affiliate of Northwestern Mutual. This authorization is subject to all
applicable legal requirements, including procedures adopted by the Directors.
During 1997, the Fund paid $21,869 in commissions to Baird. This represents .5%
of the aggregate brokerage commissions paid during 1997 and .6% of aggregate
Fund transactions. During 1998, the Fund paid $48,828 in commissions to Baird.
This represents 2.4% of the aggregate brokerage commissions paid during 1998 and
.3% of aggregate Fund transactions. During 1999, the Fund paid $34,410 in
commissions to Baird. This represents 1.2% of the aggregate brokerage
commissions paid during 1999 and less than .1% of aggregate Fund transactions.
ORGANIZATION AND CAPITAL STOCK
The Fund was incorporated in Maryland on December 22, 1983.
The Fund issues a separate class of capital stock for each Portfolio.
Each share of capital stock issued with respect to a Portfolio has a pro rata
interest in the assets of that Portfolio and has no interest in the assets of
any other Portfolio. Each share of capital stock is entitled to one vote on all
matters submitted to a vote of shareholders. Shares of a Portfolio will be voted
separately, however, on matters affecting only that Portfolio, including
approval of the Investment Advisory Agreement and changes in fundamental
investment policies of a Portfolio. The assets of each Portfolio are charged
with the liabilities of the Portfolio and their proportionate share of the
general liabilities of the Fund based on the relative asset size of the
Portfolios at the time the liabilities are incurred. All shares may be redeemed
for cash at any time.
All of the outstanding shares of each Portfolio are owned of record by
Northwestern Mutual. Shares of each Portfolio are presently being offered only
to Northwestern Mutual and its separate investment accounts used for variable
annuity contracts and variable life insurance policies. The shares held in
connection with certain of the separate investment accounts are voted by
Northwestern Mutual in accordance with instructions received from the owners of
the variable annuity contracts and variable life insurance policies. The shares
held by Northwestern Mutual as general assets are voted by Northwestern Mutual
in the same proportions as the shares held in connection with these separate
investment accounts. If applicable laws, regulations or interpretations change
so as to permit Northwestern Mutual to vote the Fund shares in its own
discretion, it may elect to do so.
As stated above, the shares of the Fund are offered to separate
investment accounts to fund both variable life insurance policies and variable
annuity contracts. Because of differences in tax treatment or other
B-27
<PAGE> 47
considerations it is possible that the interests of variable life insurance
policyowners, owners of variable annuity contracts or owners of other contracts
that may participate in the Fund in the future might at some time be in
conflict. The Board of Directors of the Fund will monitor for any material
conflicts and determine what action, if any, should be taken. Northwestern
Mutual has agreed to be responsible, at its cost, to remedy or eliminate any
irreconcilable material conflict up to and including establishing a new
registered management investment company and segregating the assets underlying
the variable annuity contracts and variable life insurance policies.
The capital stock of the Fund is divided into eleven classes
corresponding to the eleven Portfolios of the Fund. Each class is preferred over
the other classes with respect to the assets of the Portfolio to which the class
relates. Dividends and distributions, including distributions in the event of
liquidation, are payable only out of assets of the Portfolio to which the class
relates. All shares of the Fund are entitled to vote on all matters submitted to
a vote of the shareholders except that shares shall be voted by class on matters
concerning only that class, to approve an investment advisory agreement, to
approve changes in fundamental policies with respect to that class and when
otherwise required by the Investment Company Act of 1940. Shares may be redeemed
only for cash, except that capital stock of any class may be redeemed in kind
with assets of the Portfolio to which the class relates if the Directors deem
such action desirable. Each share is nonassessable and shareholders have no
preemptive or conversion rights.
Each Portfolio is a diversified series of the Fund. The Fund is an
open-end management investment company.
PURCHASE, REDEMPTION AND PRICING OF SHARES
Shares of each Portfolio are offered and redeemed at their net asset
value as next determined following receipt of a purchase order or tender for
redemption without the addition of any selling commission or "sales load" or any
redemption charge. The redemption price may be more or less than the
shareholder's cost.
The net asset value of each share of each Portfolio is the net asset
value of the entire Portfolio divided by the number of shares of the Portfolio
outstanding. The net asset value of an entire Portfolio is determined by
computing the value of all assets of the Portfolio and deducting all
liabilities, including reserves and accrued liabilities of the Portfolio.
Portfolio securities for which market quotations are readily available are
valued at current market value.
Equity securities listed on a stock exchange and all call options are
valued at the closing sale price on the stock or options exchange or, if there
has been no such sale, at the closing bid price; stock index futures contracts
and interest rate futures contracts are valued at the closing settlement price
on the commodities exchange; unlisted equity securities are valued at the
closing bid price on the over-the-counter market.
Debt securities with maturities generally exceeding one year are valued
on the basis of valuations furnished by Interactive Data Corporation, a facility
which utilizes electronic data processing techniques to report valuations for
normal institutional size trading units of debt securities, without regard to
exchange or over-the-counter prices, unless the Directors of the Fund determine
that in the case of a particular security some other value is fair.
Money market instruments and debt securities with maturities exceeding
sixty days but generally not exceeding one year are valued by marking to market,
except for the Money Market Portfolio. Marking to market is based on an average
(provided by a communication network) of the most recent bid prices or yields.
The marking to market method takes into account unrealized
B-28
<PAGE> 48
appreciation or depreciation due to changes in interest rates or other factors
which would influence the current fair values of such securities.
Securities with remaining maturities of sixty days or less, and all
debt securities of the Money Market Portfolio, are valued on an amortized cost
basis or, if the current market value differs substantially from the amortized
cost, by marking to market. Under the amortized cost method of valuation, the
security will initially be valued at the cost on the date of purchase (or, in
the case of securities purchased with more than 60 days remaining to maturity
the market value on the 61st day prior to maturity); and thereafter the
Portfolio will assume a constant proportionate amortization in value until
maturity of any discount or premium.
The value of a foreign security held by the International Equity
Portfolio is determined in its national currency as of the close of trading on
the foreign exchange on which it is traded, or as of 4:00 p.m., New York time,
if that is earlier, and that value is then converted into its U.S. dollar
equivalent at foreign exchange rates in effect at 11:00 a.m., New York time, on
the day the value of the foreign security is determined. If no sale is reported
at that time, the mean between the current bid and asked price is used.
Occasionally, events which affect the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of the New York Stock Exchange, and will therefore not be reflected in the
computation of the Portfolio's net asset value. If events materially affecting
the value of such securities occur during such period, then these securities
will be valued at fair value as determined by the management and approved in
good faith by the Directors of the Fund. Trading in securities on European and
Far Eastern securities exchanges and over-the-counter markets is normally
completed well before the close of business in New York on each day on which the
New York Stock Exchange is open. Trading in European or Far Eastern securities
generally, or in a particular country or countries, may not take place on every
New York business day. Furthermore, trading takes place in various foreign
markets on days which are not business days in New York and on which the Fund's
net asset value is not calculated. The International Equity Portfolio calculates
net asset value per share, and therefore effects sales and redemptions of its
shares, as of the close of the New York Stock Exchange once on each day on which
that Exchange is open. Such calculation does not take place contemporaneously
with the determination of the prices of many of the portfolio securities used in
such calculation and if events occur which materially affect the value of these
foreign securities, they will be valued at fair market value as determined by
the management and approved in good faith by the Directors of the Fund.
All other assets, including any securities for which market quotations
are not readily available, will be valued at their fair value as determined in
good faith by the Directors of the Fund. The net asset value is determined as of
the close of trading on the New York Stock Exchange on each day during which the
Exchange is open for trading. In accordance with the requirements of the
Investment Company Act of 1940 the Portfolios will also determine the net asset
value of their shares on any other day on which there is sufficient trading to
materially affect the value of their securities.
The Money Market Portfolio will use its best efforts to maintain a
constant net asset value per share of $1.00 (computed to an accuracy of $.005);
however, the net asset value is subject to fluctuation based upon changes in the
value of the Portfolio's securities. Accordingly, if net losses on the
Portfolio's securities for a given period exceed income after expenses, the net
asset value per share of Money Market Portfolio capital stock will decline. The
Board of Directors of the Fund will take such action as it considers appropriate
to maintain the stability of the net asset value per share. For example, the
Directors may reduce or suspend the payment of dividends if the net asset value
per share should decline below $.995 and the Directors may supplement such
dividends with other distributions if the net asset value per share should rise
above $1.005.

Payment for the shares redeemed must be made within seven days after
the evidence of ownership of such shares is tendered to the Fund; however, the
right to redeem Fund shares may be suspended, or payment of the redemption value
postponed, during any period in which the New York Stock Exchange is closed or
trading thereon is restricted, or any period during which an emergency exists,
or as otherwise permitted by the Investment Company Act of 1940.
TAXES AND DIVIDENDS
Each Portfolio is qualified or intends to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code. In order to
avoid taxation of capital gains under Subchapter M of the Code, each Portfolio,
except the Money Market Portfolio, will distribute net capital gains annually.
Net capital gains from the sale of investments will be calculated by subtracting
any unused capital loss carryforward from net realized gain for the year, as
prescribed by the Internal Revenue Code. No distribution of realized capital
gains will be made until any capital loss carryforward has been exhausted or
expired. At the end of its last fiscal year, the High Yield Bond Portfolio had
an unused capital loss carryforward of $2,519,798.
CALCULATION OF YIELD QUOTATIONS OF THE MONEY MARKET PORTFOLIO
The Money Market Portfolio's yield is its current investment income
expressed in annualized terms. The Portfolio's yield is calculated by
determining the net change in the value of a pre-existing account having a
balance of one share at the beginning of a seven-day base period. The net change
in the value of the account is divided by the value of the account at the
beginning of the period to obtain the base period return. The result is then
multiplied by 365 and divided by seven, with the resulting annualized yield
carried to the nearest hundredth of one percent. For purposes of this
calculation the net change in the value of the account reflects the value of
additional Portfolio shares purchased with dividends from the original share and
dividends declared on both the original share and any such additional shares.
The calculation reflects net investment income of the Portfolio for the period,
including accrued interest income plus or minus amortized purchase discount or
premium, less all accrued expenses, but does not include realized or unrealized
gains or losses.

APPENDIX A
Description of Ratings as Provided by the Rating Services
CORPORATE BONDS
Moody's Investors Service, Inc.
Aaa--Bonds which are rated Aaa are judged to be of the best quality.
They carry the smallest degree of investment risk and are generally referred to
as "gilt edge." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.
Aa--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they compromise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
A--Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.
Baa--Bonds which are rated Baa are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
Ba--Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and, thereby, not well
safeguarded during other good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
B--Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the security over any long period of time may be
small.
Caa--Bonds which are rated Caa are of poor standing. Such securities
may be in default or there may be present elements of danger with respect to
principal or interest.
Ca--Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings.
C--Bonds which are rated C are the lowest rated class of bonds and are
regarded as having extremely poor prospects of ever attaining any real
investment standing.
Absence of Rating: Where no rating has been assigned or where a rating
has been suspended or withdrawn, it may be for reasons unrelated to the quality
of the issue.
Should no rating be assigned, the reason may be one of the following:
B-32
<PAGE> 52
1. An application for rating was not received or accepted.
2. The issue or issuer belongs to a group of securities that are not
rated as a matter of policy.
3. There is a lack of essential data pertaining to the issue or issuer.
4. The issue was privately placed, in which case the rating is
not published in Moody's publications.
Suspension or withdrawal may occur if new and material circumstances
arise, the effects of which preclude satisfactory analysis; if there is no
longer available reasonable up-to-date data to permit a judgment to be formed;
if a bond is called for redemption; or for other reasons.
Note: Moody's applies numerical modifiers 1, 2 and 3 in each generic
ratings classification from Aa through B in its corporate bond rating system.
The modifier 1 indicates that the security ranks in the higher end of its
generic rating category; the modifier 2 indicates a mid-range ranking; and the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
Standard & Poor's
AAA--Debt rated 'AAA' has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.
AA--Debt rated 'AA' differs from the highest rated obligations only in
small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.
A--Debt rated 'A' is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in higher
rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.
BBB--Debt rated 'BBB' exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.
Debt rated 'BB', 'B', 'CCC', 'CC', and 'C' is regarded as having
significant speculative characteristics. 'BB' indicates the least degree of
speculation and 'C' the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.
BB--Debt rated 'BB' is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.
B--Debt rated 'B' is more vulnerable to nonpayment than obligations
rated 'BB', but the obligor currently has the capacity to meet its financial
commitment on the obligation. Adverse business, financial, or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.
CCC--Debt rated 'CCC' is currently vulnerable to nonpayment, and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.
B-33
<PAGE> 53
CC--Debt rated 'CC' is currently highly vulnerable to nonpayment.
C--A subordinated debt or preferred stock obligation rated 'C' is
CURRENTLY HIGHLY VULNERABLE to nonpayment. The 'C' rating may be used to cover a
situation where a bankruptcy petition has been filed or similar action taken,
but payments on this obligation are being continued. A 'C' also will be assigned
to a preferred stock issue in arrears on dividends or sinking fund payments, but
that is currently paying.
D--Debt rated 'D' is in payment default. The 'D' rating category is
used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The 'D' rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.
Plus (+) or minus(-): The ratings from 'AA' to 'CCC' may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.
r--This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk - such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.
N.R.--This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.
PREFERRED STOCKS
Moody's Investors Service, Inc.
aaa--considered to be a top-quality preferred stock. This rating
indicates good asset protection and the least risk of dividend impairment within
the universe of preferred stocks.
aa--considered a high-grade preferred stock. This rating indicates that
there is a reasonable assurance that earnings and asset protection will remain
relatively well maintained in the foreseeable future.
a--considered to be an upper-medium-grade preferred stock. While risks
are judged to be somewhat greater than in the aaa and aa classifications,
earnings and asset protection are, nevertheless, expected to be maintained at
adequate levels.
baa--considered to be medium-grade, neither highly protected nor poorly
secured. Earnings and asset protection appear adequate at present but may be
questionable over any great length of time.
ba--considered to have speculative elements and its future cannot be
considered well assured. Earnings and asset protection may be very moderate and
not well safeguarded during adverse periods. Uncertainty of position
characterizes preferred stocks in this class.
b--generally lacks the characteristics of a desirable investment.
Assurance of dividend payments and maintenance of other terms of the issue over
any long period of time may be small.
caa--likely to be in arrears on dividend payments. This rating
designation does not purport to indicate the future status of payments.
B-34
<PAGE> 54
ca--speculative in a high degree and is likely to be in arrears on
dividends with little likelihood of eventual payments.
c--lowest rated class of preferred or preference stock. Issues so rated
can be regarded as having extremely poor prospects of ever attaining any real
investment standing.
Moody's applies numerical modifiers 1, 2 and 3 in each rating
classification: the modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-range
ranking; and the modifier 3 indicates that the issue ranks in the lower end of
its generic rating category.
COMMERCIAL PAPER
Moody's Investors Service
The term "commercial paper" as used by Moody's means promissory
obligations not having an original maturity in excess of one year.
Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment capacity of rated issuers:
Issuers rated PRIME-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. PRIME-1 repayment
ability will often be evidenced by the following characteristics:
-- Leading market positions in well-established industries.
-- High rates of return on funds employed.
-- Conservative capitalization structures with moderate
reliance on debt and ample asset protection.
-- Broad margins in earnings coverage of fixed financial
charges and high internal cash generation.
-- Well-established access to a range of financial markets
and assured sources of alternate liquidity.
Issuers rated PRIME-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
Issuers rated PRIME-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term debt obligations. The effect of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and the requirement for relatively high financial
leverage. Adequate alternate liquidity is maintained.
Issuers rated NOT PRIME do not fall within any of the Prime rating
categories.
Standard & Poor's
S&P commercial paper rating is a current assessment of the likelihood
of timely payment of debt having an original maturity of no more than 365 days.
Ratings are graded into several categories ranging from "A-1" for the highest
quality obligations to "D" for the lowest. These categories are as follows:
B-35
<PAGE> 55
A-1 Commercial paper rated 'A-1' is rated in the highest category. The
obligor's capacity to meet its financial commitment on the obligation is strong.
Within this category, certain obligations are designated with a plus sign (+).
This indicates that the obligor's capacity to meet its financial commitment on
these obligations is extremely strong.
A-2 Commercial paper rated 'A-2' is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.
A-3 Commercial paper rated 'A-3' exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.
B Commercial paper rated 'B' is regarded as having significant
speculative characteristics. The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.
C Commercial paper rated 'C' is currently vulnerable to nonpayment and
is dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.
D Commercial paper rated 'D' is in payment default. The 'D' rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grace period. The 'D'
rating also will be used upon the filing of a bankruptcy petition or the taking
of a similar action if payments on an obligation are jeopardized.

NORTHWESTERN MUTUAL SERIES FUND, INC.
Notes to Financial Statements
December 31, 1999
NOTE 1 -- Northwestern Mutual Series Fund, Inc. (the "Series Fund"), is
registered as a diversified open-end investment company under the Investment
Company Act of 1940. The Series Fund consists of the Small Cap Growth Stock
Portfolio, Aggressive Growth Stock Portfolio, International Equity Portfolio,
Index 400 Stock Portfolio, Growth Stock Portfolio, Growth and Income Stock
Portfolio, Index 500 Stock Portfolio, Balanced Portfolio, High Yield Bond
Portfolio, Select Bond Portfolio and the Money Market Portfolio (the
"Portfolios"). Shares are presently offered only to The Northwestern Mutual Life
Insurance Company ("Northwestern Mutual") and its segregated asset accounts.
On April 30, 1999, two new portfolios commenced operations in the Series Fund:
Small Cap Growth Stock Portfolio and Index 400 Stock Portfolio. These two new
portfolios were each organized with 2,000,000,000 authorized shares of Common
Stock. Par value is $.01 per share. Northwestern Mutual purchased 25,010,000
shares of the Index 400 Stock Portfolio at $1.00 per share and 5,010,000 shares
of the Small Cap Growth Stock Portfolio at $1.00 per share.
NOTE 2 -- The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
Principal accounting policies are summarized below.
NOTE 3 -- Bonds are valued on the basis of prices furnished by a service which
determines prices for normal institutional size trading units of bonds, without
regard to exchange or over-the-counter prices. When quotations are not readily
available, bonds are valued at fair market value determined by procedures
approved by the Board of Directors. Stocks listed on a national or foreign stock
exchange are valued at the final sale price, or final bid price in absence of a
sale. Stocks not listed on a national or foreign stock exchange are valued at
the closing bid price on the over-the-counter market. Money market investments,
other than in the Money Market Portfolio, with maturities exceeding sixty days
but generally not exceeding one year are valued by marking to market on the
basis of an average of the most recent bid prices or yields. Money market
investments with maturities of sixty days or less and all securities in the
Money Market Portfolio are valued on an amortized cost basis or, if the current
market value differs substantially from the amortized cost, by marking to
market.
NOTE 4 -- Securities and other assets and liabilities denominated in foreign
currencies are translated into U.S. dollar amounts on the date of valuation.
Purchases and sales of securities and income items denominated in foreign
currencies are translated in U.S. dollar amounts on the respective dates of such
transactions. When the International Equity Portfolio, Balanced Portfolio and
Select Bond Portfolio purchases or sells a foreign security they may enter into
a foreign exchange currency contract to minimize currency risk from the trade
date to the settlement date of such transaction. Such foreign exchange currency
contracts are marked to market daily.
The Portfolios may enter into forward foreign currency contracts to hedge
against exchange rate risk arising from investments in securities denominated in
foreign currencies. Contracts are valued at the contractual forward rate and are
marked to market daily, with the change in market value recorded as an
unrealized gain or loss. When the contracts are closed, a realized gain or loss
is incurred. Risks may arise from changes in market value of the underlying
instruments and from the possible inability of counter parties to meet the terms
of their contracts.
The International Equity Portfolio, Balanced Portfolio and Select Bond Portfolio
do not separately report the results of operations due to changes in foreign
exchange rates on equity investments from the fluctuations arising from changes
in market prices of securities held. Such fluctuations are included with the net
realized and unrealized gain or loss from investments.
Net realized foreign exchange gains or losses arise from sales of foreign
currencies, currency gains or losses realized between the trade date and the
settlement date on security transactions, changes in foreign exchange rates on
bond investments sold, the differences between the amounts of dividends and
foreign withholding taxes recorded on the portfolio's books, and the U.S. dollar
equivalent of the amounts actually received or paid.

NOTE 5 -- The Small Cap Growth Stock, Aggressive Growth Stock, Index 400 Stock,
Growth Stock, Index 500 Stock, Balanced and Select Bond Portfolios invest in
futures contracts as an alternative to investing in individual securities. The
Portfolios could be exposed to market risk due to changes in the value of the
underlying securities or due to an illiquid secondary market. Futures contracts
are marked to market daily based upon quoted settlement prices. The Portfolios
receive from or pay to brokers an amount of cash equal to the daily fluctuation
in the value of the contracts. Such receipts or payments, known as the
"variation margin," are recorded by the Portfolios as unrealized gains or
losses. When the contract is closed, the Portfolios record a realized gain or
loss equal to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.
................................................................................
NOTE 6 -- Interest income and discounts earned are recorded daily on the accrual
basis and dividend income is recorded on the ex-dividend date or as soon as
information from foreign issuers is available. Where applicable, dividends are
recorded net of foreign dividend tax. Discounts and premiums on securities
purchased are amortized over the life of the respective securities when required
for federal income tax purposes using the effective interest method. Securities
transactions are accounted for on trade date. The basis for determining cost on
sale of securities is identified cost. For the year ended December 31, 1999,
transactions in securities other than money market investments were:

NOTE 7 -- The Series Fund and its Portfolios are parties to annually renewable
contracts pursuant to which each Portfolio pays a charge for investment
management and administrative services.
Each Portfolio pays a monthly fee for these investment advisory services at an
annual rate based on the average daily net asset values of each Portfolio. For
the Index 500 Stock Portfolio the rate is .20%, for the Index 400 Stock
Portfolio the rate is .25%, and for the Balanced, Select Bond and Money Market
Portfolios the rate is .30%. For the other Portfolios the rate for the
investment advisory fee is graded by the asset size of the Portfolio according
to the following schedule:

These amounts are paid to Northwestern Mutual Investment Services, LLC. ("NMIS")
a wholly owned subsidiary of Northwestern Mutual, which is the manager and

agreement. Other costs for each Portfolio are paid either by the Portfolios,
Northwestern Mutual, or NMIS, depending upon the applicable agreement in place.

The Small Cap Growth Stock Portfolio, International Equity Portfolio, Index 400
Stock Portfolio and the Index 500 Stock Portfolio pay their own custodian fees.
In addition, certain Portfolios pay a portion of their custodian fees indirectly
through expense offset arrangements. Custodian fees are reduced for Portfolios
that maintain compensating balances in non-interest bearing accounts. The
Portfolios could have invested the assets used to pay for the custodian fees,
had the assets not been used in the expense offset arrangements. For the year
ended December 31, 1999, the amounts paid through expense offset arrangements
are $2,137 in the Small Cap Growth Stock Portfolio, $9,164 in the Aggressive
Growth Stock Portfolio, $1,888 in the Index 400 Stock Portfolio, $5,740 in the
Growth Stock Portfolio, $377 in the Growth and Income Stock Portfolio, $6,063 in
the Index 500 Stock Portfolio and $1,227 in the High Yield Bond Portfolio.
J. P. Morgan Investment Management, Inc. ("J. P. Morgan") and Templeton
Investment Counsel, Inc. ("Templeton Counsel") have been retained under an
investment sub-advisory agreement to provide investment advice and, in general,
to conduct the management investment program of the Growth and Income Stock
Portfolio and the International Equity Portfolio, respectively. NMIS pays J. P.
Morgan .45% on the first $100 million of the combined net assets for all funds
managed for Northwestern Mutual by J. P. Morgan, .40% on the next $100 million,
.35% on the next $200 million and .30% in excess of $400 million. NMIS pays
Templeton Counsel .50% on the first $100 million of the combined net assets for
all funds managed for Northwestern Mutual by Templeton Counsel and .40% in
excess of $100 million.
NMIS has agreed to waive their management fee for the Small Cap Growth Stock
Portfolio and the Index 400 Stock Portfolio to the extent necessary so that
total operating expenses will not exceed 1.00% and .35%, respectively. For the
period April 30, 1999 to December 31, 1999, NMIS waived $5,919 and $27,990 of
fees for the Small Cap Growth Stock Portfolio and the Index 400 Stock Portfolio,
respectively.
The Small Cap Growth Stock, Aggressive Growth Stock, and Growth Stock Portfolios
paid commissions on Fund transactions to an affiliated broker in the amounts of
$3,180, $29,430, and $1,800, respectively, for the year ended December 31, 1999.
NOTE 8 -- Each Portfolio in the Series Fund has elected to be taxed as a
regulated investment company meeting certain requirements under the Internal
Revenue Code. Since each Portfolio expects to distribute all net investment
income and net realized capital gains, the Portfolios anticipate incurring no
federal income taxes.
Taxable distributions from net investment income and realized capital gains in
the Portfolios differ from book amounts earned during the period due to
differences in the timing of capital recognition and due to the reclassification
of certain gains or losses from capital to income. The differences between cost
amounts for book purposes and tax purposes are due to treatment of deferred
losses.
It is the policy of the Series Fund to reclassify the net effect of permanent
differences between book and taxable income to capital accounts on the
statements of assets and liabilities.
After October 31, 1999, the High Yield Bond Portfolio and the Select Bond
Portfolio had capital losses in the amounts of $2,850,813 and $5,182,726,
respectively. These amounts are deferred and deemed to have occurred in the next
fiscal year. For federal income tax purposes, the High Yield Bond and Select
Bond Portfolios also have a net realized capital loss of $23,977,979 and
$1,399,790, respectively, expiring in 2007. The High Yield Bond Portfolio also
has a net realized capital loss of $2,661,875, which expires in 2006. These
amounts will be carried forward to offset future net realized capital gains.
For federal income tax purposes, net unrealized appreciation (depreciation) on
open regulated futures contracts is required to be treated as realized gains
(losses).
NOTE 9 -- Dividends from net investment income and net realized capital gains
are declared each year for the Small Cap Growth Stock, Aggressive Growth Stock,
International Equity, Index 400 Stock, Growth Stock, Growth and Income Stock,
Index 500 Stock, Balanced, High Yield Bond and Select Bond Portfolios and each
business day for the Money Market Portfolio.
NOTE 10 -- Northwestern Mutual voluntarily reimburses the International Equity
Portfolio for the benefit Northwestern Mutual receives from foreign dividend
taxes charged against the Portfolio. The amount reimbursed represents
approximately 65% of the foreign dividend tax withheld from the Portfolio.
Reimbursements are recorded when foreign dividend taxes are accrued. This
voluntary reimbursement for the year ended December 31, 1999 was $1,243,988.
