Letter to Policyowners

January 31, 2002

The year just ended has been a difficult one in many ways. As the year began, most observers sensed that we were near the end of a record economic expansion, but there was considerable uncertainly as to the likely course of the economy. The stock market, traditionally a leading indicator, had already experienced a sharp drop. Other indicators were mixed, and they remained so through most of the year. The Federal Reserve responded to mounting signs of weakness with an unprecedented series of interest rate cuts.

Then in September Americans were stunned by terrorist attacks. A sharp drop when the markets reopened was followed by an encouraging rally in the fourth quarter. In November came the official announcement that a recession had begun eight months earlier.

In this difficult environment, it is understandable that some investors are feeling confused and frustrated. But our current situation is not unprecedented. Except in the technology sector, the stock market decline is far from a crash, and recession is by no means synonymous with economic disaster.

The U.S. economy has experienced nine recessions since World War II, and each has been followed by a period of economic growth. The stock market tends to move in concert with the economy, and periods of strength and weakness are inevitable. Although equities as a whole have a lengthy record of positive long-term returns, there will be intermittent periods of negative return. While experience suggests that it is reasonable to expect positive returns from stocks over the long term, we have always considered it unlikely that the 20%-plus returns of the late 1990s could be maintained.

We are convinced that professional management, broad diversification and a long-term outlook are the keys to responsible, productive investing. Owners of Northwestern Mutual Variable Life Insurance policies participate in the markets with these important advantages. The individuals who manage these Portfolios are seasoned professionals with many years of experience, people who have learned to manage through good and bad markets. Many are the same individuals who manage the corporate assets of Northwestern Mutual.

The weak equity markets of the last two years reinforce the importance of diversification, among types of investments (such as stocks, government and corporate bonds, and real estate portfolios) and within each type of investment. The broad diversification of the Portfolios underlying the variable life insurance products avoids some of the risk inherent in holding individual securities. Including different types of equity funds — for example, growth and value; large and small capitalization; domestic and international — provides valuable balance and insulation from weakness in particular market segments.

Relatively strong bond returns over the last two years provide evidence of the value of including bond funds in your portfolio. As you choose the mix of funds that is best for you, we urge you to take advantage of the services of your Northwestern Mutual Investment Services representative, who is available to help you meet your financial goals.

We want you to know about a few changes in our organization and our investment products, which we believe will provide more choices and even better service to owners of Northwestern Mutual Variable Life Insurance policies.

In this publication, we are reporting on the initial results of four new portfolios introduced in July 2001: a growth-oriented international fund; a small-cap value fund; a large-cap domestic value fund, and an asset allocation fund. Details on the objectives and management style of each of these funds, as well as the 16 other fund choices, are provided in the following pages. This broad array of investment choices provides vehicles appropriate for any investment objective, as well as ample opportunities to adjust your personal portfolio over time.

There also have been some organizational changes designed to create one cohesive, distinct organization with all the legal, regulatory and operational infrastructure to provide stronger investment advisory services to our policyowners and other clients. As of January 1, 2002, the individuals who manage Northwestern Mutual’s public market investments, including those underlying the variable annuity and variable life insurance products, the Mason Street family of mutual funds, and Northwestern Mutual’s corporate assets, are now part of a new entity, Mason Street Advisors, LLC, a registered investment advisory firm. The individuals managing your investments are the same as before, and Mason Street Advisors is a wholly owned company of Northwestern Mutual.

We thank you for your continuing confidence in Northwestern Mutual, and we look forward to being your resource for long-term financial security for many years to come.

The Northwestern Mutual Life Insurance Company

Mason G. Ross

Chairman, Mason Street Advisors

 Economic Overview and Outlook

The Economy

The economy in 2001 turned out to be weaker than most forecasters had anticipated. As the year progressed, more and more indicators pointed toward recession. The tragic events of September 11 brought sharp focus to a general sense of economic malaise, and created serious problems for certain industries, especially travel.

In November, the National Bureau of Economic Research declared officially that a recession had begun in March 2001, exactly ten years after the record economic expansion of the 1990s began. This is an unusual recession, however. In most recent slowdowns, demand has been choked by rising interest rates, inflation, or oil shortages. This time, the Federal Reserve has provided stimulus through an unprecedented series of interest rate cuts. Consumer spending has remained strong, especially in interest-sensitive areas such as housing and autos. Business inventories appear to be at a reasonable level, and productivity is holding up unusually well.

Now the main questions concern the depth and duration of the recession, and the strength of the subsequent recovery. Most observers are reasonably positive: The consensus of 55 economists surveyed by The Wall Street Journal (article published January 4, 2002) is that the economy will resume growth in the first half of 2002, with the annualized growth rate surpassing 3% by the end of the year. However, there is wide divergence among the experts, with forecasts for real growth for the full year 2002 ranging from -1.7% to 5.0%. The progress of the recovery will be determined largely by whether an initial period of inventory rebuilding is followed by a sustainable increase in capital spending.

The Equity Market

For the first time since the 1970s, the major market indices — the S&P 500 Index, the Dow Jones Industrial Average, and the Nasdaq Composite Index — all posted losses for the second consecutive year. The net downtrend was far from steady. A drop in the first quarter, most pronounced in the technology-heavy Nasdaq index, was followed by a modest rally in the summer. A sharp drop when the market reopened after September 11 was followed by a rally in the fourth quarter. Throughout the year, the market experienced tremendous volatility, with record numbers of days exhibiting sharp moves up or down.

Investors should remember that the late 1990s were a period of unprecedented equity returns. Total return of the S&P 500 Index was above 20% for five consecutive years, after surpassing 20% for only eight of the previous 30 years.

Market history offers some encouragement to investors in hope of a rebound in 2002. It has been 60 years since the major stock indexes fell for three consecutive years. That happened in 1939-1941, as fascism was sweeping through Europe and recovery from the Great Depression was just beginning. With a modest economic recovery predicted for 2002, any strength in the stock market is likely to be similarly mild. A shift in interest from large-cap to small-cap stocks, and from growth to value, makes it seem likely that market leadership will be quite different from the 1990s, when technology dominated performance.

The Bond Market

For the second consecutive year bonds substantially outperformed stocks in 2001. Total return from the Merrill Lynch Domestic Master Index was 8.3%, versus a loss of 11.8% in the S&P 500 Index.

Within the bond market, the most pronounced trend was a dramatic steepening in the yield curve, which depicts the relationship between yields on short-term bonds and long-term bonds. Short-term yields dropped dramatically, in response to easing by the Federal Reserve, while yields on 30-year bonds remained essentially unchanged throughout the year.

Another important trend in the bond market was a tightening of interest rate spreads between U.S. Treasury bonds and corporate bonds during the year. At the beginning of the year, the spread was wider than usual, reflecting strong demand for Treasuries and concern about the performance of corporate bonds in a slowing economy. The spread narrowed over the next few months; then Treasuries rallied sharply in the market turmoil that followed September 11. Near the end of the year, as some economic data proved more positive than expected, investors began to regain confidence in corporate bonds, pushing prices up and yields down. Accordingly, corporate bonds outperformed Treasury securities for the first time in four years.

 Small Cap Growth Stock Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Maximum long-term appreciation of capital	Strive for the highest possible rate of capital appreciation by investing in companies with potential for rapid growth.	$291.45 million

The Small Cap Growth Stock Portfolio owns the stocks of emerging growth companies, with the objective of maintaining a median market capitalization of $1 billion. The range of market capitalization is generally between $200 million and $3 billion. The investment process involves detailed studies of individual companies. Factors evaluated include the growth rates of revenues and earnings, opportunities for margin expansion, financial strength and quality of management. Since growth stock portfolios tend to react strongly to changes in financial and economic markets, as well as to changes in the prospects for individual companies, returns of this Portfolio can vary considerably from time to time. A higher level of risk (with risk defined as variability of returns over time) is accepted for the potential of greater long-term returns.

The year just ended, with a slowing economy, the aftermath of the technology boom of prior years, and external shocks to the markets, was particularly difficult for the small-cap growth category of equities. As a defensive measure, certain holdings in the travel and consumer cyclical sectors were eliminated during the third quarter, and there has been a degree of concentration in non-cyclical industry groups such as business services, many of which are categorized in the Industrials sector. Some of the Portfolio’s large holdings in industries such as health care and specialty finance that have limited exposure to broad economic trends have performed well; these include Lincare, Patterson Dental and Radian Group.

As the market responds to increasing signs of economic recovery, there appears to be considerable opportunity for this portfolio, since small cap stocks traditionally perform well in the early stages of a recovery. Accordingly, holdings at the end of 2001 reflect moves to increase exposure to more cyclical industry groups. New or increased holdings include Coach Leatherware, which should benefit from an improving consumer environment; Airgas, a gas distributor; and oil service companies such as Patterson-UTI Energy and National-Oilwell. In anticipation of a recovery, the Portfolio is overweighted in health care and technology, two sectors considered to have strong long-term growth prospects.

Since the Portfolio invests primarily in small capitalization issues, the indices that best reflect the Portfolio’s performance are the Standard & Poor’s (S&P) SmallCap 600 Index and Russell 2000 Index.

The Standard & Poor’s SmallCap 600 Index is an unmanaged index of 600 selected common stocks of smaller U.S.-based companies compiled by Standard & Poor’s Corporation. As of December 31, 2001, the 600 companies in the composite had median market capitalization of $525.2 million and total market value of $376.2 billion. The SmallCap 600 represents approximately 2.6% of the market value of Compustat’s database of over 10,000 equities.

The Russell 2000 Index measures the performance of the 2,000 smallest companies in the Russell 3000 Index. The Russell 3000 Index measures the performance of the 3,000 largest US companies based on total market capitalization. These 3,000 companies represent approximately 98% of the investable US equity market. As of December 31, 2001, the average market capitalization of companies in the Russell 3000 was $4.6 billion; the median market capitalization was $732 million. Market capitalization of companies in the Index ranged from $487 billion to $147 million.

The Russell 2000 Index represents approximately 8% of the total market capitalization of the Russell 3000. As of December 31, 2001, the average market capitalization of companies in the Russell 2000 was approximately $530 million; the median market capitalization was approximately $410 million. The largest company in the index had a total market capitalization of approximately $1.4 billion.

This chart assumes an initial investment of $10,000 made on 4/30/99 (commencement of the Fund’s operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 T. Rowe Price Small Cap Value Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Long-term growth of capital	Invest in small companies whose common stocks are believed to be undervalued.	$21.00 million

The T. Rowe Price Small Cap Value Portfolio invests in companies with market capitalization of $1 billion or less whose current stock prices do not appear to reflect their underlying value. For this Portfolio, value is defined broadly, with consideration given to stock price relative to long-term growth prospects and business franchises, in addition to typical value measures such as assets, current earnings and cash flow. Many of the Portfolio’s holdings are quality companies that have been overlooked by the investment community.

The Portfolio typically holds approximately 100 stocks with average market capitalization somewhat smaller than the Russell 2000 Value Index, its major performance benchmark, as consideration of smaller companies often makes it possible to invest in higher quality companies without paying a premium. The average price-earnings ratio of stocks in the Portfolio is generally close to that of the Index, but quality measures such as return on equity and financial strength are higher. The major emphasis is on selection of individual stocks, with secondary consideration given to industry weightings in order to keep the Portfolio broadly diversified among economic sectors.

Small-cap value stocks as a group were up in 2000 and 2001, when the broad market averages were down significantly, after underperforming in the previous years of strong large-cap equity markets; this portfolio therefore provides an excellent diversification opportunity for holders of large capitalization stocks. The Portfolio has performed in line with the Russell 2000 Value Index in the five months since it was added to the investment choices available to Northwestern Mutual policyowners. Major holdings that contributed to performance in recent months were Brown & Brown, an insurance brokerage firm; Ruby Tuesday, a casual dining restaurant chain; XTO Energy, an independent producer of oil and natural gas producer; and Allied Capital, which provides debt and equity capital to middle-market companies.

 Aggressive Growth Stock Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Maximum long-term appreciation of capital	Strive for the highest possible rate of capital appreciation by investing in companies with potential for rapid growth.	$1.34 billion

The Aggressive Growth Stock Portfolio owns the stocks of emerging growth companies, generally with market capitalizations of less than $10 billion. Since growth stock portfolios tend to react strongly to changes in financial and economic markets, as well as to changes in the prospects for individual companies, returns of this Portfolio can vary considerably from time to time. A higher level of risk (with risk defined as variability of returns over time) is accepted for the potential of greater long-term returns. The Portfolio’s focus in stock selection is on the individual companies’ ability to generate revenue, expand profit margins and maintain solid balance sheets; industry sector selection is of secondary importance.

In a difficult and volatile market environment, the Aggressive Growth Stock Portfolio has underperformed its benchmark, the S&P MidCap 400 Index, over the last year. Communication, technology and energy have been among the poorer performing industry groups. More defensive holdings such as Investors Financial Services, Fiserv, Radian Group and Concord EFS in the financial services sector and Patterson Dental in health care have held up well. Technology holdings benefited from a rally in the final months of the year.

In anticipation of a recovery, the Portfolio’s holdings are being adjusted to provide more participation in growth-oriented cyclicals.

Aggressive Growth Stock Portfolio		-19.87%		8.42%		12.57%
S&P 400 Index		-0.60%		16.11%		15.02%

Since the Portfolio invests primarily in medium-capitalization (Mid Cap) issues, the index that best reflects the Portfolio’s performance is the S&P MidCap 400 Index. This is a capitalization-weighted index that measures the performance of the mid-range sector of the U.S. stock market.

As of December 31, 2001, the 400 companies in the composite had median market capitalization of $1.7 billion and a total market value of $830.1 billion. The MidCap 400 represents approximately 5.7% of the market value of Compustat’s database of over 10,000 equities.

This chart assumes an initial investment of $10,000 made on 12/31/91. Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 International Growth Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Long-term capital appreciation	Invest in stocks of companies outside the U.S. that are expected to experience above-average growth.	$26.90 million

The International Growth Stock Portfolio invests in common stocks of companies that are headquartered or trade primarily on exchanges outside the United States and that are expected to grow more rapidly than market averages. Holdings are selected for their individual characteristics and growth prospects, with only minor consideration given to size, geography, and industry group. Stocks are selected through fundamental analysis of their financial soundness and potential for growth, with emphasis on distinctiveness of products or services and strong market positions. Stocks under consideration are carefully analyzed to make sure the promise of growth is not already reflected in the stock price, with technical analysis used as a further check on the relationship between price, value and market trends.

At the end of 2001, the Portfolio was moderately concentrated in consumer cyclicals, including retailers and leading international auto makers Porsche AG, BMW and Honda, each of which has particular international strength in its market segment. Also in the automotive industry is Beru AG, a small German company with unique technology for monitoring tire pressure. A major retail holding is Belluna, a leading mail order company in Japan. Defensive balance for these economically sensitive issues is provided by consumer non-cyclical holdings in foods, beverages, tobacco and pharmaceuticals.

The Portfolio is somewhat overweighted in technology, with exposure concentrated in low-risk companies with proprietary products. These include Tandberg ASA of Norway, which makes videoconferencing equipment; Swiss-based Logitech, which makes computer mice and web cameras; and Philips Electronics, which makes a variety of consumer electronics, semiconductors and medical systems. Another theme is support services for business, with holdings in Thiel Logistik, a provider of logistics services to hospitals; Serco Group in facilities management; and Aggreko, which provides auxiliary power.

Holdings are concentrated in Europe, which represents 78% of the Portfolio.

As depicted in the graph, the International Growth Portfolio is compared against the Morgan Stanley Capital International EAFE (“Europe-Australasia-Far East”) Index. The index is composed of approximately 1,100 companies in 20 countries in Europe and the Pacific Basin. The objective of the index is to reflect the movements of stock markets in these countries by representing an unmanaged (indexed) portfolio within each country. The index is constructed so that companies chosen represent about 60% of market capitalization in each market; industry composition of the market is reflected; and a cross section of large, medium, and small capitalization stocks is included, taking into account liquidity concerns. The index is calculated in U. S. dollars. The Index cannot be invested in directly and does not include sales charges.

This chart assumes an initial investment of $10,000 made on 7/31/01 (commencement of the Portfolio’s operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards.

 Franklin Templeton International Equity Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Long-term appreciation of capital through diversification into markets outside the United States	Participate in the growth of foreign economies by investing in securities with high long-term earnings potential relative to current market values.	$716.41 million

The Franklin Templeton International Equity Portfolio offers the opportunity to participate in the growth of companies in countries throughout the world, particularly those with expanding economies. In selecting investments, the principal focus is on identifying undervalued stocks of companies with strong finances and good long-term growth opportunities, rather than on choosing regions of the world in which to invest. The Portfolio is normally fully invested in equity securities.

The Portfolio’s value-driven management style enabled it to significantly outperform its major benchmark, the EAFE index, during 2001. However, total return was negative, as the downward trend continued in world economies and equity markets trended generally down.

A majority of the Portfolio’s holdings are in Europe, where the January 2002 introduction of the physical euro has been a positive influence. The common currency should provide impetus for further convergence of European economies, increasing transparency of transactions and simplifying cross-border mergers. The new physical euro encourages consumers to spend old currency they may have been hoarding and also makes price comparisons among countries easier. If these positives lead to strength in the euro, the Portfolio will benefit from its non-hedging strategy.

Asia remains underweighted, as economic malaise in Japan and elsewhere in the region prevails. Very modest Latin American holdings are in Brazil and Mexico, where Telefonos de Mexico experienced solid performance for the year. Telecommunications holdings in other countries delivered mixed results.

At present, there are no widespread trends in international markets; it is very much a stock picker’s market, in which Templeton’s strength in fundamental analysis is proving advantageous. The Portfolio’s largest holding, Stora Enso, a Finnish paper company, registered a modest gain for the year. Other large holdings that performed well include Cheung Kong Holdings, a Hong Kong real estate developer, and Societé Bic, a French consumer products company famous for its disposable pens, lighters and razors. Some longtime holdings finally proved rewarding near the end of 2001; these include Marks & Spencer, a British retailer undergoing a successful restructuring, and Akzo Nobel, a Dutch chemical company identified several years ago as a quality stock selling at a bargain price. Some trading opportunities were created by the worldwide market weakness after September 11; performance benefited from positions taken in late September in Alcatel, a French networking company, and Nortel, a Canadian telecommunications company.

The International Equity Portfolio is managed for Northwestern Mutual by Templeton Investment Counsel, Inc.

As depicted in the graph, the Franklin Templeton International Equity Portfolio is compared against the Morgan Stanley Capital International EAFE (“Europe-Australasia-Far East”) Index. The index is composed of approximately 1,100 companies in 20 countries in Europe and the Pacific Basin. The objective of the index is to reflect the movements of stock markets in these countries by representing an unmanaged (indexed) portfolio within each country. The index is constructed so that companies chosen represent about 60% of market capitalization in each market; industry composition of the market is reflected; and a cross section of large, medium, and small capitalization stocks is included, taking into account liquidity concerns. The index is calculated in U. S. dollars. The Index cannot be invested in directly and does not include sales charges.

This chart assumes an initial investment of $10,000 made on 4/30/93 (commencement of the Portfolio’s operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards.

A key factor in stock selection is the choice of industries with good earnings potential, based on analysis of economic trends to determine their impact on various sectors of the economy. Stock selection is made through “top down” analysis: first industry and market sector choices are made based on the economic environment, and then the most promising companies within each sector are selected as holdings. A strategy of this portfolio is to go beyond the most familiar “blue chip” names to seek out medium-sized companies with strong positions in their markets whose stock prices do not reflect their potential for growth. Diversification across 70 to 90 stocks in a wide range of industry groups reduces the Portfolio’s risk profile.

Like essentially all equity funds, the Growth Stock Portfolio had a negative total return for 2001, but annualized return of 11.0% for the last five years was above that of the S&P 500 Index. Relative to the Index, the Portfolio is most overweighted in the Consumer Discretionary sector, where the emphasis is on growth-oriented retailers that are expanding nationally. These include Kohl’s, Wal-Mart and Walgreen, which have been among the best performing retail stocks. Harley-Davidson, which has a dominant share in its unique market, has also contributed to overall performance.

The Portfolio remains underweighted in the technology sector. However, the two largest holdings within this volatile sector, Microsoft and Electronic Data Systems, have performed better during 2001 than the Index. General Electric, the Portfolio’s second largest position, is actually underweighted relative to the Index; this stock has been hurt in recent months by its exposure to insurance and aerospace. Among other large holdings, PepsiCo, Fiserv and Pfizer have performed relatively well, largely because of their defensive nature.

The Portfolio continues to focus on quality and good earnings consistency, while gradually increasing positions in industry groups likely to benefit from an improving economy. Recent additions have been made to holdings in the strongest technology companies and to more market-sensitive stocks in the financial sector, including Charles Schwab and Marsh & McLennan.

The Standard & Poor’s 500 Composite Stock Price Index is an unmanaged index of 500 selected common stocks, most of which are listed on the New York Stock Exchange. The Index is heavily weighted toward stocks with large market capitalizations and represents approximately two-thirds of the total market value of all domestic common stocks.

This chart assumes an initial investment of $10,000 made on 5/3/94 (commencement of operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 J.P. Morgan Select Growth & Income Stock Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Long-term growth of capital and income, consistent with moderate investment risk	Actively manage a portfolio of equity securities with a goal of exceeding the total return of the S&P 500 Index.	$548.67 million

J.P. Morgan Select Growth & Income Stock Portfolio invests mainly in large-capitalization stocks, with a focus on seeking the best values in the market based on long-term earnings forecasts. A sector balance very close to that of the S&P 500 Index is normally maintained, with the emphasis on undervalued stocks within each industry group; a valuation discipline mandates the sale of stocks regarded as overvalued. More focus is placed on capital appreciation and dividend growth than on current dividends. The Portfolio is normally fully invested in equity securities.

In the highly volatile stock market of 2001, the Portfolio’s strategy of stock selection based on fundamental research accompanied by a strong valuation discipline proved effective. Total return from the Growth and Income fund was negative, but more than four percentage points better than the benchmark S&P 500 Index. Performance was also helped by the policy of maintaining industry weightings close to those of the market. At a time when some investors were reluctant to hold technology stocks, the Portfolio benefited from large positions in technology leaders such as Microsoft, Intel and IBM.

Among the Portfolio’s best performing stocks were Cendant, a real estate and travel company experiencing a turnaround; TJX Companies, a core retail holding; and CIT Financial and Alza, both of which were acquired during the year. Performance relative to the Index benefited also from substantial overweights in Tyco International and Philip Morris, which were up for the year.

In the past year, a weak market has made it possible to upgrade the quality of holdings without paying a significant premium. The emphasis has been on companies with pronounced financial strength that could prosper even in a poor economy. In the months ahead, special consideration will be given to holdings with greater operating and financial leverage that have the potential to benefit from a recovering economy.

The J.P. Morgan Select Growth & Income Stock Portfolio is managed for Northwestern Mutual by J.P. Morgan Investment Management, Inc.

Sector Allocation 12/31/01

The J.P. Morgan Select Growth & Income Stock Portfolio was formerly named the Growth and Income Stock Portfolio. The name change took effect on May 4, 2001. The Portfolio’s investment objective did not change.

Long-term growth of capital and income	Invest in larger American companies that exhibit value characteristics relative to S&P 500 Index.	$40.72 million

The Capital Guardian Domestic Equity Portfolio invests mainly in large companies with well-known names, proven track records, and a history of dividends. This value-oriented Portfolio emphasizes stocks that have lower price-earnings ratios, lower price to book value ratios, and higher dividend yields than the S&P 500 Index.

The selection process focuses on individual stocks that are underpriced relative to their inherent value and long-term prospects, based largely on Capital Guardian’s solid research capabilities. Industry selection receives minor consideration, and industry weightings may diverge significantly from the major market indices. At the end of 2001, the Portfolio was overweighted relative to the index in financial services, industrials, and utilities, and underweighted in consumer stocks and information technology.

The Portfolio has outperformed the S&P 500 Index in the five months since it was added to the investment choices available to Northwestern Mutual policyowners. In a volatile and generally down market, performance benefited from a cautious approach of avoiding holdings likely to suffer earnings problems in a weakening economy. Performance in the last quarter of 2001 was boosted by the opportunistic addition of quality companies including United Technologies, Applied Materials, Inc. and Sabre Holdings, all of which rebounded significantly after experiencing sharp drops in the wake of the September terrorist attacks.

The Capital Guardian Domestic Equity Portfolio is managed for Northwestern Mutual by Capital Guardian Trust Company.

The Standard & Poor’s 500 Composite Stock Price Index is an unmanaged index of 500 selected common stocks, most of which are listed on the New York Stock Exchange. The Index is heavily weighted toward stocks with large market capitalizations and represents approximately two-thirds of the total market value of all domestic common stocks.

This chart assumes an initial investment of $10,000 made on 7/31/01 (commencement of operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 Index 500 Stock Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Long-term capital appreciation through cost-effective participation in broad market performance	Invest in a portfolio designed to approximate the composition and returns of the S&P 500 Index.	$1.82 billion

The Index 500 Stock Portfolio is designed to achieve results that approximate the performance of the Standard & Poor’s 500 Composite Stock Price Index. As of December 31, 2001, the 500 stocks in the Index had a median market capitalization of $8.4 billion and total market value of $10,463 billion. Of the 500 stocks, 420 are listed on the New York Stock Exchange, 78 on NASDAQ, and 2 on the American Stock Exchange.

This composite of 500 stocks of large U.S.-based companies, compiled by Standard & Poor’s Corporation, is generally regarded as a good proxy for the large-capitalization portion of the U.S. equity market; the Portfolio therefore enables contract owners to participate in overall performance of the equity market. The Portfolio continues to achieve the objective of matching the results of the S&P 500 before expenses.

 Asset Allocation Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Realize highest total return, including current income and capital appreciation, consistent with reasonable investment risk	Flexible policy of allocating assets among stocks, bonds and cash, with mix adjusted to capitalize on changing financial markets and economic conditions.	$40.12 million

The Asset Allocation Portfolio invests in seven categories of assets: large capitalization stocks, small capitalization stocks, foreign stocks, investment grade bonds, below investment grade bonds, convertible securities and cash equivalents. The proportion of investments in each category is adjusted as appropriate to take advantage of market trends and opportunities, and securities within each category are actively managed by a team of investment professionals. The Portfolio is managed to maintain broad diversification, while blending asset classes to achieve both capital appreciation and current income.

For much of the last year, the Asset Allocation Portfolio has been managed defensively, in the belief that an increasingly fragile economy was likely to move into a recession. Bond holdings were concentrated in the high quality investment grade sector. As bonds provided higher returns than stocks for the year, the bond segment of the Portfolio was an important contributor to performance.

As stock prices moved down in the first half of 2001, despite aggressive easing by the Federal Reserve, The Portfolio’s managers took advantage of periodic opportunities to selectively increase equity exposure, which reached 56% in early September. When the market reopened after September 11, the equity exposure was reduced, as a defensive move. Then, as a weak and volatile market created buying opportunities, equity exposure was increased. Further additions were made to the equity position as an economic recovery in 2002 began to seem more likely. At the end of 2001, with 59% of the portfolio in equities, the Portfolio was in a neutral position; the normal range of equity as a proportion of the total is 45% to 75%. This neutral position will likely be retained until there is clearer evidence of the timing and strength of the potential recovery.

In the graph, the Fund is compared against three indices representing the three major components of the Fund: equities, fixed income and cash equivalent investments. The indices cannot be invested in directly and do not include sales charges.

The Merrill Lynch Domestic Master Index is an unmanaged market value weighted index comprised of U.S. government, mortgage and investment-grade corporate bonds. The Index measures the income provided by, and the price changes of, the underlying securities.

The Standard & Poor’s 500® Composite Stock Price Index is an unmanaged index of 500 selected common stocks, most of which are listed on the New York Stock Exchange. The Index is heavily weighted toward stocks with large market capitalizations and represents approximately two-thirds of the total market value of all domestic common stocks.

The Merrill Lynch 91-Day Treasury Bill Index is comprised of a single issue purchased at the beginning of each month and held for a full month. The issue selected at each month-end rebalancing is the outstanding Treasury bill that matures closest to, but not beyond, three months from the rebalancing date.

This chart assumes an initial investment of $10,000 made on 7/31/01 (commencement of operations). Returns shown include fee waivers and deductions for all Fund expenses. In the absence of fee waivers, total return would be reduced. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards. Small-cap stocks also may carry additional risk. Small or newer issuers are more likely to realize more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both more volatile and more speculative.

 Balanced Portfolio

Objective:	Portfolio Strategy:	Net Assets:
A high level of current income and capital growth with a low risk profile	Achieve consistent returns and low volatility by diversifying among assets.	$3.01 billion

In order to capitalize on changing financial market and economic conditions, the Balanced Portfolio’s asset allocation is adjusted as appropriate among three investment classes: stocks, bonds and money market instruments. The equity portion of the Portfolio is indexed, meaning that the Portfolio is designed to achieve results that approximate the performance of the Standard & Poor’s 500 Composite Stock Price Index, which is generally regarded as a good proxy for the overall U.S. equity market. The bond portion of the Portfolio is actively managed, with investments in high quality bonds adjusted frequently as to maturity, market sectors and duration. Liquidity is maintained by holding a portion of the Portfolio in money market investments, which are high quality short-term debt securities.

The target asset mix for the Balanced Portfolio is established and adjusted according to an asset valuation model designed to gauge the relative attractiveness of stocks versus bonds. In the highly volatile equity market of 2001, the Portfolio’s managers took advantage of opportunities to sell on strength and buy on weakness. Accordingly, the equity position was reduced after the rally early in the year, adjusted frequently during the summer months, and increased when the market plunged at the end of the third quarter.

Performance was boosted by excellent results from the bond portion of the Portfolio, which is managed actively, with a strategy very similar to that of the Select Bond Portfolio. Bonds as a whole provided higher returns than stocks for the second consecutive year, and the Portfolio benefited from the bond managers’ correct positioning with regard to duration and market sectors throughout the year.

Relative Performance

Average Annual Total Return
For Periods Ended December 31, 2001
	1 Year		5 Years		10 Years

In the graph, the Portfolio is compared against three indices representing the three major components of the Portfolio: equities, fixed income, and cash equivalent investments.

The Standard & Poor’s 500 Composite Stock Price Index is an unmanaged index of 500 selected common stocks, most of which are listed on the New York Stock Exchange. The index is heavily weighted toward stocks with large market capitalizations and represents approximately two-thirds of the total market value of all domestic common stocks.

The Merrill Lynch Domestic Master Index is an unmanaged market value weighted index comprised of U.S. Government, mortgage and investment-grade corporate bonds. The index measures the income provided by, and the price changes of, the underlying securities.

The Merrill Lynch 91-Day T-Bill Index is comprised of a single issue purchased at the beginning of each month and held for a full month. The issue selected at each month-end rebalancing is the outstanding Treasury Bill that matures closest to, but not beyond, three months from the rebalancing date.

This chart assumes an initial investment of $10,000 made on 12/31/91. Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 High Yield Bond Portfolio

Objective:	Portfolio Strategy:	Net Assets:
High current income and capital appreciation with moderate risk	Generate superior performance by investing in a diversified mix of fixed income securities rated below investment grade.	$147.67 million

Investing in a portfolio of high yield bonds provides investors who can accept a moderate level of risk with a high level of current income, coupled with the opportunity for capital gains. Holdings of particular interest include investments in entities that have the possibility of a positive event, such as a significant improvement in credit rating or earnings or a change in ownership. In a high yield portfolio, some credit losses over time are inevitable; high coupons and diversification across many holdings mitigate the impact of individual securities on the performance of the total Portfolio.

The Portfolio performed significantly better than its benchmark, the Lehman Brothers High Yield Intermediate Market Index, during 2001, a year in which bonds substantially outperformed stocks. This strong performance at a time of economic uncertainty and weak equity markets provides a reminder that high yield bonds are a medium-risk asset class that can provide valuable balance and diversification to investors whose holdings are concentrated in equities.

The Portfolio had a total return of 5.03% during 2001, despite a weak economy and volatile financial markets. As the economy moved into recession, fundamental credit conditions in the high yield market turned negative. Corporate earnings and cash flows were generally weak. Rating agency downgrades rose sharply. Defaults reached near-record levels and post-default recoveries were well below historical averages. At times, liquidity conditions in the high yield market were poor and price volatility increased sharply.

The Portfolio was managed with a defensive investment posture during 2001, in an effort to preserve capital and minimize credit losses. The Portfolio maintained an above average weight in the upper-tier double-B quality sector. Credit selection was a major driver of return performance. Stronger and better-capitalized companies within the high yield category were emphasized. Company financial results were closely monitored throughout the year, and holdings in companies experiencing serious earnings or liquidity problems were reduced or eliminated.

Stable industry sectors such as cable TV, utilities, gaming and finance were emphasized. Holdings in economically sensitive industry sectors such as steel, chemicals, paper, aerospace and automotive were minimized. While the Portfolio had holdings in the telecommunications industry, most of its exposure was in the wireless segment, which performed better than the wireline segment. The Portfolio benefited from strong relative performance in the broadcasting, transportation, finance and gaming sectors, as well as the cellular telephone segment of telecommunications.

The total return performance for the High Yield Bond Portfolio is shown in comparison with the Lehman Brothers High Yield Intermediate Market Index. The Lehman Brothers index is an appropriate measure of portfolio performance since it has a quality and maturity profile that resembles the High Yield Bond Portfolio.

The Lehman Brothers High Yield Intermediate Market Index is made up of dollar-denominated, nonconvertible, SEC publicly registered fixed rate noninvestment grade issues. The bonds will have remaining maturities of between one and ten years and have an outstanding par value of at least $100 million. Yankee and global bonds (SEC registered) of issuers in G-7 countries are included. Original issue zero coupon bonds and step-up coupon structures are also included; however, the index excludes pay-in-kind (PIK) bonds. Each bond must be rated Ba1 or lower by Moody’s Investor Service. If a Moody’s rating is unavailable, the bonds must be rated BB+ or lower by Standard & Poor’s, or by Fitch if an S&P rating is unavailable. A few unrated bonds are included in the index; to be eligible they must have previously held a high yield rating or have been associated with a high yield issuer. The index is an unmanaged market value weighted index and measures the income provided by, and the price changes of, the underlying securities.

This chart assumes an initial investment of $10,000 made on 5/3/94 (commencement of operations). Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 Select Bond Portfolio

Objective:	Portfolio Strategy:	Net Assets:
A stable and relatively high level of long-term total return and preservation of capital	Invest in high grade corporate bonds, U.S. government bonds and bonds of government agencies.	$405.41 million

The Select Bond Portfolio invests primarily in high quality debt securities, mainly government bonds, corporate bonds and mortgage-backed securities. Exposure to market sectors is adjusted as yield spreads change among the various classes of securities. Duration and maturities are altered with moderate adjustments in recognition or anticipation of interest rate changes.

In the second consecutive year in which bonds provided significantly higher returns than equities, the Select Bond Portfolio substantially outperformed its major benchmark, the Merrill Lynch Domestic Master Index. During 2001, the yield curve steepened dramatically; a major determinant of performance was therefore correctly predicting changes in the curve. Early in the year, the Portfolio was overweighted in bonds with shorter durations, which have risen in price as short-term interest rates have dropped. Yields on bonds of longer duration, in which the Portfolio has been underweighted, have experienced little change, reflecting investor concerns about inflation and economic growth.

The Portfolio also took advantage of changes in spreads between Treasury securities and corporate bonds over the course of the year. As the year began, there was an overweight in Treasury securities, which were the best performing asset class in 2000. In the first trading days of 2001, the Portfolio’s managers took advantage of unusually wide spreads to purchase quality corporate bonds that offered good value.

The market for mortgage-backed bonds has experienced a wave of refinancings in response to falling interest rates. An underweighting in this market sector has been beneficial; also sensitivity to this trend has been mitigated by a concentration of mortgage-related securities in commercial mortgages, which often have steep prepayment penalties, and GNMA-backed securities, which tend to be more difficult to refinance.

Percentage Holdings 12/31/01

The Corporate Bonds sector includes bonds of companies headquartered outside the United States. The Government and Government Agencies category includes taxable bonds of domestic and foreign governments and a small position in municipal bonds. Consistent with the Portfolio’s stated parameters, no more than 10% of the Portfolio is invested in foreign securities, and no more than 10% is invested in high-yield securities.

Relative Performance

Average Annual Total Return
For Periods Ended December 31, 2001
	1 Year		5 Years		10 Years
Select Bond Portfolio		10.37%		7.13%		7.31%
Merrill Lynch Domestic Master Index		8.33%		7.43%		7.29%

Since the Portfolio invests broadly in U.S. Government, mortgage and corporate bonds, a useful basis for comparing returns is the Merrill Lynch Domestic Master Index. The index is an unmanaged market value weighted index comprised of U.S. Government, mortgage and investment-grade corporate bonds. The index measures the income provided by, and the price changes of, the underlying securities.

This chart assumes an initial investment of $10,000 made on 12/31/91. Returns shown include deductions for management and other fund expenses, and reinvestment of all dividends. Returns exclude deductions for separate account sales loads and account fees. Past performance is not predictive of future performance. Investment return and principal value will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Total returns shown on page 4 reflect mortality and expense risk charges and other charges deducted from the assets of the separate account. The cost of insurance protection, which is not reflected in the returns shown on this chart, would make the returns significantly lower. Investors are urged to obtain a personalized illustration of historical performance which reflects the cost of insurance protection.

 Money Market Portfolio

Objective:	Portfolio Strategy:	Net Assets:
Maximum current income consistent with liquidity and stability of capital	Achieve stability of capital by investing in short-term debt securities.	$458.69 million

The Money Market Portfolio, which invests only in high quality commercial paper and other short-term debt securities with maturities generally not exceeding one year, is the least risky of the Portfolios.

The most notable effect on short-term interest rates during 2001 was the Federal Reserve’s 11 interest rate cuts, which totaled 475 basis points. During the first half of the year, the Portfolio’s performance relative to its benchmark, the Merrill Lynch 91-day Treasury Bill Index, was hurt by average maturity somewhat shorter than the Index. During the fourth quarter, the Portfolio’s weighted average maturity was extended, to a high of approximately 70 days, versus 50 to 55 days for the index. At year end, the Portfolio’s average maturity remained longer than the Index.

AN INVESTMENT IN THE MONEY MARKET PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE PORTFOLIO SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, THERE IS NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE SO IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE PORTFOLIO.

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the Small Cap Growth Stock Portfolio, T. Rowe Price Small Cap Value Portfolio, Aggressive Growth Stock Portfolio, International Growth Portfolio, Franklin Templeton International Equity Portfolio, Index 400 Stock Portfolio, Growth Stock Portfolio, J.P. Morgan Select Growth and Income Stock Portfolio, Capital Guardian Domestic Equity Portfolio, Index 500 Stock Portfolio, Asset Allocation Portfolio, Balanced Portfolio, High Yield Bond Portfolio, Select Bond Portfolio and Money Market Portfolio (constituting Northwestern Mutual Series Fund, Inc., hereafter referred to as the “Funds”) at December 31, 2001, the results of each of their operations for the year or period then ended, the changes in each of their net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2001 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

Northwestern Mutual Series Fund, Inc.

Notes to Financial Statements

December 31, 2001

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, T. Rowe Price Small Cap Value Portfolio, Aggressive Growth Stock Portfolio, International Growth Stock Portfolio, Franklin Templeton International Equity Portfolio, Index 400 Stock Portfolio, Growth Stock Portfolio, J.P. Morgan Select Growth & Income Stock Portfolio, Capital Guardian Domestic Equity Portfolio, Index 500 Stock Portfolio, Asset Allocation 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 July 31, 2001, four new portfolios commenced operations in the Series Fund: T. Rowe Price Small Cap Value Portfolio, International Growth Stock Portfolio, Capital Guardian Domestic Equity Portfolio and the Asset Allocation Portfolio. These four 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 each of the International Growth Stock, Capital Guardian Domestic Equity, and the Asset Allocation Portfolios at $1.00 per share and 5,010,000 shares of the T. Rowe Price Small Cap Value 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 amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Principal accounting policies are summarized below.

Note 3 — 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. Bonds are valued on the basis of prices furnished by a service which determines prices for normal institutional size trading units of bonds. 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. When quotations are not readily available, securities are valued at fair value determined by procedures approved by the Board of Directors.

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 Growth Stock Portfolio, Franklin Templeton International Equity Portfolio, Asset Allocation Portfolio, Balanced Portfolio and Select Bond Portfolio purchases or sells a foreign security they may enter into a foreign exchange currency contract to minimize market risk for 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 valued at the contractual forward rate 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 counterparties to meet the terms of their contracts.

The International Growth Stock Portfolio, Franklin Templeton International Equity Portfolio, Asset Allocation Portfolio, Balanced Portfolio and Select Bond Portfolio do not separately report the results of operations due to changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized or unrealized gain or loss from investments.

108

 Notes to Financial Statements

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, 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, Asset Allocation, Balanced and Select Bond Portfolios invest in futures contracts as an alternative to investing in individual securities. The Small Cap Growth Stock, Aggressive Growth Stock, Index 400 Stock, Growth Stock, Index 500 Stock, Asset Allocation, Balanced and Select Bond 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 issues 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 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 period ended December 31, 2001, 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 at an annual rate based on the average daily net asset values of each Portfolio. For the T. Rowe Price Small Cap Value Portfolio the rate is .85%, 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

These amounts are paid to Northwestern Mutual Investment Services, LLC (“NMIS”), a wholly owned company of Northwestern Mutual, which is the manager and investment adviser of the Fund. Northwestern Mutual is also a party to the agreement. Other costs for each Portfolio are paid either by the Portfolios, Northwestern Mutual, or NMIS depending upon the applicable agreement in place. Effective January 1, 2002, Mason Street Advisers, LLC (“MSA”), a wholly owned company of Northwestern Mutual, will replace NMIS as the manager and investment advisor of the Fund.

The Small Cap Growth Stock Portfolio, T. Rowe Price Small Cap Value Portfolio, Aggressive Growth Stock Portfolio, International Growth Stock Portfolio, Franklin Templeton International Equity Portfolio, Index 400 Stock Portfolio, Growth Stock Portfolio, J.P. Morgan Select Growth & Income Stock Portfolio, Capital Guardian Domestic Equity Portfolio, Index 500 Stock Portfolio, Asset Allocation Portfolio, and High Yield Bond 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 period ended December 31, 2001, the amounts paid through expense offset arrangements are $4,075 in the Small Cap Growth Stock Portfolio, $586 in the T. Rowe Price Small Cap Value Portfolio, $6,329 in the Aggressive Growth Stock Portfolio, $3,356 in the Index 400 Stock Portfolio, $4,118 in the Growth Stock Portfolio, $2,986 in the J.P. Morgan Select Growth & Income Stock Portfolio, $274 in the Capital Guardian Domestic Equity Portfolio, $4,281 in the Index 500 Stock Portfolio, $488 in the Asset Allocation Portfolio, and $1,970 in the High Yield Bond Portfolio.

J.P. Morgan Investment Management, Inc. (“J.P. Morgan”), Templeton Investment Counsel, Inc. (“Templeton Counsel”), T. Rowe Price Associates, Inc. (“T. Rowe Price”) and Capital Guardian Trust Company (“Capital Guardian”) have been retained under an investment subadvisory agreement to provide investment advice and, in general, to conduct the management investment program of the J.P. Morgan Select Growth & Income Stock Portfolio, the Franklin Templeton International Equity Portfolio, the T. Rowe Price Small Cap Value Portfolio and the Capital Guardian Domestic 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 pays T. Rowe Price an annual rate of .60% of the Portfolio’s average daily net assets. NMIS pays Capital Guardian a flat annual fee of $375,000 on the Portfolio’s assets of $100 million or less and .275% on net assets in excess of $100 million.

The Growth Stock, Aggressive Growth Stock, Small Cap Growth Stock and Asset Allocation Portfolios paid commissions on Fund transactions to an affiliated broker in the amounts of $1,362, $178,992, $3,786 and $2,046, respectively, for the year ended December 31, 2001.

Note 8 — Each of the Portfolios of the Series Fund has elected to be taxed as a regulated investment company meeting certain requirements under the Internal Revenue Code. Since each 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 gains recognition and due to the reclassification of certain gains or losses from capital to income. The differences between cost amounts for book

110

 Notes to Financial Statements

purposes and tax purposes are principally due to treatment of deferred losses.

It is the policy of the Portfolios 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, 2001, the Aggressive Growth Stock, International Growth Stock, Franklin Templeton International Equity, J.P. Morgan Select Growth & Income Stock, Capital Guardian Domestic Equity, Index 500 Stock and High Yield Bond Portfolios had capital losses in the amounts of $12,647,928, $914,957, $4,193,591, $6,639,459, $117,050, $707,261 and $6,432,818, respectively. The International Growth Stock and Franklin Templeton International Equity Portfolios had currency losses in the amounts of $16,787 and $23,291, respectively. These amounts are deferred and deemed to have occurred in the next fiscal year. For Federal income tax purposes, the Small Cap Growth Stock, International Growth Stock, Franklin Templeton International Equity, Index 400 Stock, Growth Stock, J.P. Morgan Select Growth & Income Stock, Capital Guardian Domestic Equity, Asset Allocation and Balanced Portfolios also have net realized capital losses of $25,189,147, $162,404, $11,599,888, $2,803,777, $52,222,224, $18,238,809, $51,512, $144,649 and $4,462,390, respectively, which will be carried forward to offset future net realized gains. The amounts expire in 2009. The High Yield Bond Portfolio has a net realized capital loss of $58,963,786. The amounts expire as follows: $2,661,875 in 2006, $23,977,979 in 2007, $21,128,704 in 2008 and $11,195,228 in 2009. The Select Bond Portfolio utilized $6,607,991 of prior capital loss carry forwards.

For Federal income tax purposes, net unrealized appreciation (depreciation) on open futures contracts is generally 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, T. Rowe Price Small Cap Value, Aggressive Growth Stock, International Growth Stock, Franklin Templeton International Equity, Index 400 Stock, Growth Stock, J.P. Morgan Select Growth & Income Stock, Capital Guardian Domestic Equity, Index 500 Stock, Asset Allocation, Balanced, High Yield Bond and Select Bond Portfolios and each business day for the Money Market Portfolio.

Note 10 — Northwestern Mutual voluntarily reimburses the Franklin Templeton 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. These voluntary reimbursements for the years ended December 31, 2001 and December 31, 2000 were $1,296,498 and $830,396, respectively.

*  Differs from disclosures on Schedules of Investments due primarily to timing of recognition of certain gains and losses for tax purposes.

The difference between book basis and tax-basis unrealized appreciation is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on certain futures contracts.

Northwestern Mutual Variable Life Account

December 31, 2001

Note 1 — Northwestern Mutual Variable Life Account (“the Account”) is registered as a unit investment trust under the Investment Company Act of 1940 and is a segregated asset account of The Northwestern Mutual Life Insurance Company (“Northwestern Mutual”) used to fund variable life insurance policies.

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 and disclosure of contingent 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 — All assets of each Division of the Account are invested in shares of the corresponding Portfolio of Northwestern Mutual Series Fund, Inc. and the Russell Insurance Funds (collectively known as “the Funds”). The shares are valued at the Funds’ offering and redemption prices per share. The Funds are diversified open-end investment companies registered under the Investment Company Act of 1940.

Note 4 — Dividend income from the Funds is recorded on the record date of the dividends. Transactions in the Funds’ shares are accounted for on the trade date. The basis for determining cost on sale of Funds’ shares is identified cost. Purchase and sales of the Funds’ shares for the year ended December 31, 2001 by each Division are shown below:

Note 5 — A deduction for mortality and expense risks is determined daily and paid to Northwestern Mutual. Generally, for Variable Life policies issued before October 11, 1995, and Variable Complife policies issued on or after October 11, 1995 the deduction is at an annual rate of .50% and .60%, respectively, of the net assets of the Account. A deduction for the mortality and expense risks for the Variable Executive Life policies issued on or after March 3, 1998 and Variable Joint Life polices issued on or after December 10, 1998 are determined monthly at an annual rate of .75% of the amount invested in the Account for the Policy for the first ten Policy years, and .30% thereafter. The mortality risk is that insureds may not live as long as estimated. The expense risk is that expenses of issuing and administering the policies may exceed the estimated costs.

Certain deductions are also made from the annual, single or other premiums before amounts are allocated to the Account. These deductions are for (1) sales load, (2) administrative expenses, (3) taxes and (4) a risk charge for the guaranteed minimum death benefit.

Additional mortality costs are deducted from the policy annually and are paid to Northwestern Mutual to cover the cost of providing insurance protection. This cost is actuarially calculated based upon the insured’s age, the 1980 Commissioners Standard Ordinary Mortality Table and the amount of insurance provided under the policy.

Note 6 — Northwestern Mutual is taxed as a “life insurance company” under the Internal Revenue Code. The variable life insurance policies which are funded in the Account are taxed as part of the operations of Northwestern Mutual. Policies provide that a charge for taxes may be made against the assets of the Account. Generally, for Variable Life policies issued before October 11, 1995, Northwestern Mutual charges the Account at an annual rate of .20% of the Account’s net assets and reserves the right to increase, decrease or eliminate the charge for taxes in the future. Generally, for Variable Complife policies issued on or after October 11, 1995, and for Variable Executive Life policies issued on or after March 2, 1998, and Variable Joint Life policies issued on or after December 10, 1998, there is no charge being made against the assets of the Account for federal income taxes, but Northwestern Mutual reserves the right to charge for taxes in the future.

Note 7 — The Account is credited for the policyowners’ net annual premiums at the respective policy anniversary dates regardless of when policyowners actually pay their premiums. Northwestern Mutual’s equity represents any unpaid portion of net annual premiums. This applies to Variable Life and Variable Complife policies only.
