LETTER TO SHAREHOLDERS

JAMES D. ERICSON

In this first annual report to investors in the Mason Street series of mutual
funds, we are pleased to report excellent investment performance. Both equity
and bond markets have risen since the Funds began offering shares a year ago,
with the stock market, as measured by the Standard & Poor's 500(R) Index,
delivering an extraordinary 47.9 percent total return for the 12 months ended
March 31, 1998. All of the Mason Street equity funds have benefited from this
market strength, and the Aggressive Growth Fund outperformed the two indices of
small-capitalization stocks with which it is compared. The bond market has been
strong, as well, and each of the three bond funds has outperformed the index
with which it is compared. Of course, past performance cannot be considered an
indication of future performance; this applies equally to the markets in general
and to these particular Funds.

The forces behind this continued market strength are the same as in recent years
- - a steadily expanding economy virtually devoid of inflation. For nearly 20
years, the Federal Reserve Bank and most of its counterparts around the world
have been practicing sound monetary policies: in order to conquer inflation,
they have been willing to risk slow growth and even recession. It now appears
that the goal of price stability has been achieved. The positive surprise has
been that there has been no major recession, in large part because technological
advances are producing major gains in productivity. In addition, the expansion
of capitalism throughout the world, accompanied by increasingly free trade, is
generating non-inflationary growth by expanding markets for consumer and
industrial products.

A recently published study has compared the rapid pace of technological advance
of the late 20th century to the discovery of electricity near the end of the
19th century. After electricity was discovered, many years passed before the
economy realized its benefits because manufacturers were slow to adapt new
systems that took full advantage of electric power. If the analogy holds true,
there is a possibility that advances in computer technology could drive economic
growth and improve living standards for many years to come.

The only major negative force affecting world markets today is the economic
crisis in Asia. With sharply devalued currencies and shaky economies, Asian
nations, which were formerly active importers, have less ability to purchase
U.S. consumer and industrial products. At the same time, countries with devalued
currencies can use their productive capacity to flood world markets with goods
that are cheap in dollars, creating difficult competitive situations for other
global manufacturers. However, initial statistics about the first quarter of
1998 indicate that the domestic economy is so strong that the impact of weakened
demand from Asia is overshadowed. Still, there are signs that the problems in
Asia are beginning to exert downward pressure on demand in some sectors,
especially computers.

In recent years, the stock market has moved rather steadily upward; there has
not been a major setback since 1990. The bond market has also been generally
strong, though not as consistently as the stock market. Although both stocks and
bonds may continue to perform well, there are limits. Stock prices today are
quite high by almost any traditional measure. Bond prices, too, have already
reflected most of the positive factors in the market and the economy.

Over the last ten years, many new investors have come into the market. This
trend can be attributed partially to demographics, as baby boomers move into an
age group when saving begins to supplant spending. Increased demand for
financial assets has been among the factors driving stock prices higher. The
news of soaring stock prices has attracted even more investors, some of whom
have unrealistic expectations. There is the possibility that some of these new
investors will panic and begin selling as the market returns to a normal pattern
of volatility; if that happens, the result will be even wider swings up and
down.

Markets do fluctuate; this is a reality of investing. While we see no reason to
expect a near-term slump, we cannot expect the economy and markets to continue
improving at the current pace. We continue to enjoy the current favorable
environment, while placing our major focus on investing for the long term. We
urge you to maintain a long-term view as well.

We thank you for selecting Northwestern Mutual's Mason Street FundsSM, and we
look forward to investing for you for many years.

OVERVIEW AND OUTLOOK

THE ECONOMY

During 1997, the domestic economy continued its seven-year trend of moderate
growth with minimal inflation, low interest rates and very low unemployment. A
favorable combination of technology improvements, plentiful supplies of basic
commodities such as oil, and stable monetary policies are keeping inflation low.
Low interest rates encourage capital investment, which stimulates the industrial
sector while improving productivity. For consumers, modest income gains can
translate to real improvements in living standards, as confident consumers spend
and invest, providing further strength for the economy. The strong economy has
bolstered tax revenues, enabling the Federal government to develop a balanced
budget for 1999, following 30 years of deficits.

In early 1998, continued low interest rates stimulated capital spending, while
strong job growth and low inflation inspired a high level of consumer
confidence, driving strong consumption trends. Since consumer spending accounts
for two-thirds of gross domestic product, many economists have recently raised
their forecasts of growth for 1998 to the 3 to 3.5 percent range.

Source: U.S. Department of Commerce. Year-to-year percentage change in Real

THE EQUITY MARKET

The equity market continued its unprecedented rise during 1997 and early 1998.
For the 12 months ended March 1998, the Standard & Poor's 500R Index provided
investors an extraordinary 47.9 percent total return.

At the end of March 1998, the Dow Jones Industrial Average was on the verge of
breaking through the 9000 level; the S&P 500R Index was within one percentage
point of its record level. Excellent performance of smaller-capitalization and
technology stocks during the first quarter of 1998 pushed the NASDAQ Composite
to an all-time high; this index has risen over 50% during the last 12 months and
nearly 17% in the first quarter alone. Markets in Europe have also been
extraordinarily strong over the last year, especially during the first quarter
of 1998. Only in Asia, where financial problems are rampant, have markets been
down over the last year; one sign of possible improvement in the region is a
modest increase in Japan's Nikkei Index during the first calendar quarter of
1998.

MARCH 31, 1998

THE BOND MARKET

The last 12 months have been quite good for bond performance, as interest rates
dropped substantially. When the Federal Reserve left interest rates unchanged in
March, the bond market, which had considered tighter monetary policy a
possibility, strengthened further. However, tighter monetary policy, which could
drive bond prices down, seems a possibility for the next few months because
economic growth remains strong.

The impact of the economic crisis in Asia on the U.S. economy has been minimal
to date. For the U.S. bond market, Asian problems have been a plus, as investors
seeking safety purchase U.S. securities. If economic conditions in Asia improve
and investment funds begin to flow back into the region, this could be negative
for the U.S. markets.

The prospect for faster economic growth without inflation may create a new
paradigm for bond managers. In the past, stronger economic growth was considered
a signal to sell bonds, since rising interest rates drive bond prices down. In
an economy without inflation, more stable performance of bonds is a possibility.

MASON STREET FUNDS

AGGRESSIVE GROWTH STOCK FUND

OBJECTIVE: To seek long-term growth of capital primarily by investing in the
common stocks of companies that can be expected to increase their sales and
earnings at a pace that will exceed the growth rate of the U.S. economy over an
extended period.

PORTFOLIO: Primarily common stocks of small and medium-sized companies.

STRATEGY: To locate and invest in companies with above-average potential for
growth.

NET ASSETS: $43,510,325

The Aggressive Growth Stock Fund owns the stocks of emerging growth companies,
generally with market capitalizations of less than $3 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 Fund 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 Fund performed well during its first year, with total returns that surpassed
the two Wilshire indexes with which it is compared, as well as the S&P 500(R)
Index. Small-capitalization stocks in general performed well during this 12-
month period, following a period of underperformance relative to larger issues.

The Fund's focus in stock selection is on the individual companies' ability to
generate revenue, expanding profit margins and solid balance sheets; industry
sector selection is of secondary importance. However, opportunities tend to
cluster in certain industry groups or sectors. The Fund is concentrated in four
sectors in which there are numerous companies with particularly promising
prospects for growth: technology, business services, consumer cyclicals and
healthcare.

Performance of the Fund's technology sector has been enhanced by a concentration
in software companies, rather than in equipment. The position in healthcare has
been increased, with more emphasis on medical devices and supplies, which are
less dependent on third-party reimbursement than health services. The energy
position has been reduced, with most of the remaining stocks concentrated in
deep water drilling for natural gas, a segment where capacity is tight. The
broad category of business and personal services remains a major area of
interest, with positions in consulting firms and companies that benefit from the
trend to outsourcing by businesses.

Since the Fund invests primarily in small and medium-capitalization issues, the
indices that best reflect the Fund's performance are the Wilshire Next 1750
Index and Wilshire Small Cap Index. The indices cannot be invested in directly
and do not include sales charges.

The Wilshire Next 1750 is an unmanaged, equally weighted index. Included in this
index are those stocks which are ranked 750 to 2500 by market capitalization in
the Wilshire 5000. The largest sectors represented in this index are financial
services, consumer services and basic industry. Its average market
capitalization is approximately $888.7 million as of March 31, 1998.

The Wilshire Small Cap Index is a subset of the Wilshire Next 1750 and includes
250 stocks chosen based upon their size, sector and liquidity characteristics.
Each stock is equally weighted in this unmanaged index. The average market
capitalization is approximately $981.6 million as of March 31, 1998. The largest
sector weightings include financial services, consumer services and technology.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

Stocks of smaller or newer companies, such as those held in this Fund, 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.

     <F3> At March 31, 1998, the aggregate cost of securities for federal income
          tax purposes was $30,413,146 and the net unrealized appreciation of 
          investments based on that cost was $12,120,610 which is comprised of 
          $12,425,733 aggregate gross unrealized appreciation and $305,123 
          aggregate gross unrealized depreciation.

MARCH 31, 1998

INTERNATIONAL EQUITY FUND

OBJECTIVE: To seek long-term appreciation of capital by investing primarily in
the common stocks of companies outside the U.S.

PORTFOLIO: Primarily common stocks of companies in foreign countries.

STRATEGY: To locate and invest in the undervalued stocks of foreign companies
offering the greatest discounts to their long-term values.

NET ASSETS: $30,896,757

The International Equity Fund offers investors the opportunity to participate in
the growth of companies in countries throughout the world. The Fund is managed
with a disciplined approach to long-term value, with special attention to
balance sheet quality. Investments are selected based mainly on the
attractiveness of individual securities and geographic regions; industry focus
is a secondary consideration.

International markets have delivered widely varied performance over the last
year. The Fund is concentrated in Europe, where all markets are up and 12-month
increases in some markets, particularly in southern Europe, are as high as 40%.
European financial services stocks have performed particularly well. Crisis
conditions in Asian financial markets have driven stocks down sharply, with
drops in major indexes ranging from 7.5% in Japan (the largest market by far) to
more than 70% in Indonesia. However, most Asian markets rallied in the first
calendar quarter of 1998, and markets in the region remain quite volatile. The
Fund's Asian holdings are concentrated in Hong Kong, where the market is 15%
below the year-ago level.

At the end of March, the Fund held an 11% cash position as a result of recent
cash inflows and the sale of some securities. It is anticipated that this cash
position will be reduced as buying opportunities present themselves in the next
quarter.

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

As depicted in the graph, the International Equity Fund 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 indices are 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 graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

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.

MASON STREET FUNDS

GROWTH STOCK FUND

OBJECTIVE: To seek long-term growth of capital by investing in companies
believed to have above-average earnings growth potential; current income is
secondary.

PORTFOLIO: Diversified mix of high-quality growth stocks in medium and large
companies.

STRATEGY: To analyze economic trends to determine their impact on various
sectors and industries and to select high-quality stocks from industries with
the best earnings potential.

NET ASSETS: $39,035,559

The Growth Stock Fund is invested in high-quality companies of large- to medium-
capitalization with strong financial characteristics and the ability to generate
internal growth. 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. The Fund remains close to fully invested with
S&P futures used at times to maintain the desired degree of market exposure.

The Growth Stock Fund performed well during its first year, in line with the
market as a whole. Relative to the S&P 500R Index, the Fund is overweighted in
consumer staple and consumer cyclical stocks, which have benefited from
continued strength in consumer spending. The healthcare sector is now
underweighted relative to the market, following the reduction of positions in
several stocks that had generated large gains. Energy and Technology weightings
are approximately equal to the market; increases in the prices of many
technology stocks are making it difficult to find good values in this sector.
Investments in several initial public offerings, including Steelcase, Benckiser
N.V. and Keebler Foods have proven quite successful.

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 index cannot be invested in directly
and does not include sales charges.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

MARCH 31, 1998

GROWTH AND INCOME STOCK FUND

OBJECTIVE: To seek long-term growth of capital and income by investing primarily
in dividend-paying common stocks.

PORTFOLIO: Primarily common stocks of medium and large companies identified as
strong candidates for significant long-term returns.

STRATEGY: To actively manage a portfolio of selected equity securities with a
goal of out-performing the total return of the Standard & Poor's 500 Composite
Stock Price Index ("S&P 500R Index").

NET ASSETS: $39,329,618

The Growth and Income Fund 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 500R Index is normally
maintained, with the emphasis on undervalued stocks within each sector; a
valuation discipline mandates the sale of stocks regarded as overvalued. The
last 12 months have been a challenging time for the value-oriented management
style that characterizes this Fund, as a few favorite names have been a major
force in driving the equity market to record heights.

At the end of March, the Fund's three largest holdings were quality companies in
the healthcare field; Warner-Lambert has contributed importantly to the Fund's
performance. In energy, the focus is on domestic refiners, such as Tosco, and on
oil service providers, rather than the major multi-national oil companies. A
newer large holding is StarWood Lodging Trust, a real estate investment trust 
with sound management, good growth prospects, and a very favorable, though
complex, tax structure. In finance, regional banks are more prominent than the
money-center banks, which have more international exposure; the largest holding
is First Union Corporation, which is beginning to benefit from an acquisition
made last year. Many other holdings are strong companies with unrealized or
unrecognized potential; these include DuPont, a genuine blue chip company that
is ripe for restructuring; Union Pacific, a strong transportation company with
short-term operational problems; and Kmart, a retailer that appears to have
undergone a successful turnaround.

The Growth and Income Stock Fund is managed for Northwestern Mutual Investment
Services, Inc. by J.P. Morgan Investment Management, Inc.

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 index cannot be invested in directly
and does not include sales charges.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

MASON STREET FUNDS 

INDEX 500 STOCK FUND

OBJECTIVE: To seek investment results that approximate the performance of the
S&P 500R Index, by investing in stocks included in the S&P 500R Index. Because
the S&P 500R Index is an unmanaged index, its return does not reflect the
deduction of expenses that would exist with a mutual fund. 

FOCUS: To capture broad market performance, at low cost, by investing in a
portfolio modeled after a broadly based stock index.

NET ASSETS: $47,814,136

The Index 500 Stock Fund is designed to achieve results that approximate the
performance of the Standard & Poor's 500 Composite Stock Price Index. This
composite of 500 stocks of large companies, compiled by Standard & Poor's
Corporation, is generally regarded as a good proxy for the overall U.S. equity
market. The Fund therefore enables investors to participate in overall
performance of the U.S. equity market. In its first year of operation, the Fund
achieved its objective.

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 index cannot be invested in directly
and does not include sales charges.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

ASSET ALLOCATION FUND

OBJECTIVE: To seek to realize as high a level of total return, including current
income and capital appreciation, as is consistent with reasonable investment
risk. The Fund will follow a flexible policy for allocating assets among common
stocks, bonds and cash.

PORTFOLIO: The normal range of investments is 50-70% stocks, 25-35% bonds and 0-
15% cash equivalents. Up to 50% of the stock allocation may be invested in
foreign stocks.

STRATEGY: To adjust the mix between asset sectors to capitalize on the changing
financial markets and economic conditions.

NET ASSETS: $36,133,250

The Asset Allocation Fund 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 the Fund in each category is adjusted as
appropriate to take advantage of market trends and opportunities, and securities
within each category are actively managed.

The Fund benefited from an emphasis on equities during its first year of
operation, as the stock market continued to soar, led by large-capitalization
stocks, which make up 30% of the Fund's holdings. Foreign investments,
particularly Asian stocks, have been modest since the Fund's inception; with
some signs of improvement in Asia, there may be opportunities for new
investments in the region. Within the bond sector of the Fund, the main focus is
on investment-grade bonds, as historically narrow yield spreads limit the
attractiveness of assuming the additional risk of holding a large position in
below investment-grade bonds. A 6% cash position at the end of March makes it
possible to take advantage of new investment opportunities that may arise.

TOTAL RETURN
For the 12 months ended March 31, 1998
- -------------------------------------------------------
Asset Allocation Fund
(Class A - without initial sales charge)         28.51%
- -------------------------------------------------------
S&P 500(R) Index                                 47.90%

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

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 does 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.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

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. Smaller 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.

MASON STREET FUNDS

HIGH YIELD BOND FUND

OBJECTIVE: To seek high current income and capital appreciation by investing
primarily in fixed income securities that are rated below investment-grade by
the major rating agencies.

PORTFOLIO: Diversified mix of below investment-grade fixed income securities,
commonly known as "junk bonds."

STRATEGY: To identify attractive investment opportunities through rigorous
industry and credit analysis and to generate superior performance by selecting
companies with stable or improving credit fundamentals.

NET ASSETS: $34,172,241

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 solid
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 defaults over time are inevitable; high coupons
and diversification across many holdings mitigate the impact of defaults on the
total portfolio.

During its first year of operation, the Mason Street High Yield Bond Fund
significantly outperformed the Lehman Brothers High Yield Intermediate Market
Index. This strong performance can be attributed to insightful selection of
market sectors and individual securities, the selective inclusion of undervalued
preferred stocks, and the relatively high proportion of positive to negative
credit developments in the Fund's portfolio.

In recent months, the Fund's strategy has been guided by several major themes. A
strong emphasis has been placed on sectors that are generally considered less
cyclical than the overall market. Heavily cyclical issues have seemed unduly
risky and overpriced at this stage in the economic cycle. In line with this
approach, a strong presence has been maintained in the leisure sector, which
includes entertainment, gaming and lodging investments. Gaming companies in
particular have experienced strength, in large part because of industry
consolidation and the entry of large investment-grade real estate investment
trusts (REITs) as new investors in the sector. Increasing emphasis has been
placed on the rapidly growing telecommunications industry, with holdings
concentrated in alternative facilities-based telephone providers operating in
territories with favorable competitive conditions. To date these investments
have performed well.

The Fund has also benefited from its commitment to diversification through
international investing. The Fund's international exposure has been repositioned
in recent months, with a renewed emphasis on Canada and Western Europe and a
reduction of exposure to Latin American and Asian markets. Overall, selective
emerging market opportunities provided a net benefit to results, and the Fund
remains committed to pursuing value in these markets. The current risk/reward
relationships in the marketplace, however, seem to warrant a relatively
conservative international posture for the immediate future.

Throughout the year the Fund has remained essentially fully invested, with cash
balances maintained at no more than 5% of assets. At the end of the fiscal year,
the Fund is positioned conservatively with a balanced sector mix and strong
overall asset quality.

TOTAL RETURN
For the 12 months ended March 31, 1998
- -------------------------------------------------------
High Yield Bond Fund
(Class A - without initial sales charge)         22.95%

Lehman Brothers High Yield
Intermediate Market Index                        14.47%
- -------------------------------------------------------

The total return performance for the High Yield Bond Fund 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 Fund. The index
cannot be invested in directly and does not include sales charges.

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 graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

Bonds and other debt obligations are affected by changes in interest rates and
the creditworthiness of their issuers. High yield bonds generally have greater
price swings and higher default risks than investment-grade bonds.

MASON STREET FUNDS     

MUNICIPAL BOND FUND

OBJECTIVE: To seek a high level of current income exempt from federal income
taxes, consistent with preservation of capital, by investing primarily in
investment-grade municipal obligations.

PORTFOLIO: Diversified investment-grade bonds, with the ability to invest up to
20% of assets in lower-rated securities.

STRATEGY: To actively manage the portfolio to take advantage of changes in
interest rates, quality, sector and maturity of fixed income securities.

NET ASSETS: $28,644,592

The Municipal Bond Fund is managed with a balanced focus on income, total
return, quality of securities, and avoidance of federal income taxes. There are
five major classes of securities in the Fund: revenue bonds, general obligation
bonds, pre-refunded bonds, insured bonds, and money market investments, which
are cash equivalents. For revenue bonds, interest and principal is paid from
revenue from a specific source which the bonds fund, such as a tollway system or
a municipal power agency. General obligation bonds are secured by the general
credit of the issuing municipality, which can generally raise taxes as necessary
to meet obligations. Insured bonds are guaranteed by insurance companies such as
Municipal Bond Individual Assurance Corporation (MBIA) or the Financial Guaranty
Insurance Company (FGIC)<F1>. Pre-refunded bonds are backed by an escrow of
securities, usually U.S. Treasury securities.  The securities in the escrow are
selected to meet the interest payments and to pay off the pre-refunded bonds on
their first call date. As indicated in the accompanying chart, the quality of
securities held in the Fund is quite high, with 72% of total market value
invested in bonds that are either insured or have been pre-refunded.

The Fund performed well during its first year of operation, with total return a
full percentage point higher than the Lehman Brothers Municipal Bond Index, with
which it is compared. This strong performance resulted mainly from favorable
selection of securities, combined with management of the Fund's interest rate
exposure, which benefited from a drop in interest rates. Because the Fund was
established at a low point in the market, most holdings have large unrealized
gains. Changes in holdings have therefore been minimal, to avoid subjecting
shareholders to excessive capital gains taxes. At present, municipal bonds are
cheap relative to taxable bonds because of an unusually large supply of
municipals due to the many new issues encouraged by the low interest rate
environment. This relative cheapness of municipal bonds should be considered by
investors who may be making a choice between a municipal fund and a taxable bond
fund.

<F1> Insurance applies only to the prompt payment of principal and interest of 
     the bonds in the Fund and does not remove the market risks associated with 
     your investment. There is also no guarantee that the insurer will be able 
     to meet its commitments.

The total return performance for the Municipal Bond Fund is shown in comparison
with the Lehman Brothers Municipal Bond Index. The Lehman Brothers index is an
appropriate measure of portfolio performance since it has a quality and maturity
profile that resembles the Municipal Bond Fund. The index cannot be invested in
directly and does not include sales charges.

The Lehman Brothers Municipal Bond Index includes municipal bonds that have: a
minimum credit rating of Baa; been issued as part of an issuance of at least $50
million; a maturity value of at least $3 million; a maturity of at least one
year; and been issued after December 31, 1990. Recently the index included
40,924 issues totaling $600 billion par amount. The index represents
approximately 30% of the municipal bond market capitalization.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

SELECT BOND FUND

OBJECTIVE: To seek high income and capital appreciation, consistent with
preservation of capital.

PORTFOLIO: Diversified investment-grade corporate, Treasury and government
agency bonds, with maturities generally exceeding one year.

STRATEGY: To actively manage the portfolio to take advantage of changes in
interest rates, quality and maturity of fixed income securities.

NET ASSETS:  $29,260,753

The Select Bond Fund performed well for the year just ended, outperforming the
index with which it is compared. This strong performance resulted from several
factors. An aggressive interest rate posture early in the year generated good
results when interest rates subsequently declined. However, a defensive interest
rate posture for the last six months has detracted from performance somewhat as
interest rates declined further. Bond selection has contributed to performance,
as corporate bonds, especially those of banks and financial service companies,
have responded well to continued economic strength. Holdings in commercial
mortgage-backed securities, which are essentially a higher-yield substitute for
high-quality corporate bonds, boosted overall returns during the latter months
of the year. The Fund's present posture is defensive, with an underweighting in
corporate bonds balanced by an overweighted position in mortgage-backed and
asset-backed securities, which perform well when interest rates rise.

parameters, no more than 15% of the portfolio is invested in foreign securities,
and no more than 15% is invested in high yield securities.

Select Bond Fund

Since the Fund invests broadly in U.S. government, mortgage and corporate bonds,
the graph depicts an appropriate comparison to 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. The
index cannot be invested in directly and does not include sales charges.

This graph assumes an initial investment of $10,000 made in Class A and Class B
shares, with all sales charges on March 31, 1997 (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. Returns on p. 3 reflect the maximum sales charge for Class
A and a 4% contingent deferred sales charge for Class B.

NOTES TO FINANCIAL STATEMENTS

NOTE 1
Mason Street Funds, Inc. was incorporated under the laws of the state of
Maryland on August 30, 1996 as an open-end investment company under the
Investment Company Act of 1940. Mason Street FundsSM consist of the Aggressive
Growth Stock Fund, International Equity Fund, Growth Stock Fund, Growth and
Income Stock Fund, Index 500 Stock Fund, Asset Allocation Fund, High Yield Bond
Fund, Municipal Bond Fund and the Select Bond Fund, collectively known as "the
Funds." The Funds commenced operations on March 31, 1997 at $10.00 per share
with 1,200 shares in each of the Funds owned by Northwestern Mutual Life
Insurance Company ("Northwestern Mutual"). On April 1, 1997, Northwestern Mutual
invested an additional $225 million in Mason Street FundsSM; $25 million in the
Class A shares in each of the Funds.

Each Fund offers two classes of shares: Class A shares with an initial sales
charge up to 4.75% and Class B shares with contingent deferred sales charge of
5.0% to 0% over a period of up to six years. Each class of shares has equal
rights with respect to voting privileges.

Organizational costs and initial registration expenses are being deferred and
amortized over the period of benefit, but not to exceed 60 months from the
Funds' commencement of operations. These costs, totaling $417,215, were advanced
by Northwestern Mutual and were reimbursed by the Funds equally.

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 in the  following Notes.

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 using 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 with maturities exceeding 60 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 60 days or less 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 into U.S. dollar amounts on the respective dates of such
transactions. When the International Equity Fund, Asset Allocation Fund and
Select Bond Fund purchase or sell a foreign security they may enter into a
foreign exchange currency contract to minimize market risk from the trade date
to the settlement date of such transaction. Such foreign exchange currency
contracts are marked to market daily.

The Funds 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 Fund, Asset Allocation Fund and Select Bond Fund 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.

Net realized and unrealized 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, and the differences between the
amounts of dividends and foreign withholding taxes recorded on the Funds' books
and the U.S. dollar equivalent of the amounts actually received or paid.

NOTE 5
The Aggressive Growth Stock Fund, Growth Stock Fund, Index 500 Stock Fund, Asset
Allocation Fund, Municipal Bond Fund and the Select Bond Fund invest in futures
contracts as an alternative to investing in individual securities. The
Aggressive Growth Stock Fund, Growth Stock Fund, Index 500 Stock Fund, Asset
Allocation Fund, Municipal Bond Fund and the Select Bond Fund 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 Funds 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
Funds as unrealized gains or losses. When the contract is closed, the Funds
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.

For federal income tax purposes, net unrealized appreciation (depreciation) on
open futures contracts is generally required to be treated as realized gains
(losses).

NOTE 6
Income, Fund expenses, realized and unrealized gains and losses are allocated
daily to each class of shares based on the value of shares outstanding for the
Aggressive Growth Stock Fund, International Equity Fund, Growth Stock Fund,
Growth and Income Stock Fund, Index 500 Stock Fund and Asset Allocation Fund.
Dividends and other distributions are calculated in a similar manner and are
declared and distributed to shareholders annually for these Funds. For the High
Yield Bond Fund, Municipal Bond Fund and Select Bond Fund, income and Fund
expenses are allocated daily to each class of shares based on the value of
settled shares. Realized and unrealized gains and losses are allocated daily to
each class of shares based on the value of shares outstanding. Dividends and
other distributions are calculated in a similar manner. Income dividends are
declared daily, paid monthly. Capital gain dividends are declared and
distributed annually for these Funds.

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

NOTE 7
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 on securities purchased in the Funds are
amortized over the life of the respective securities using the effective
interest method. Premiums for the Municipal Bond Fund are amortized to the
remaining life or earlier call date, whichever is earlier. Securities
transactions are accounted for on trade date. The basis for determining cost on
sale of securities is identified cost. For the twelve months ended March 31,
1998, transactions in securities other than money market investments were:

J.P. Morgan Investment Management Inc. ("J.P. Morgan") and Templeton Investment
Counsel, Inc. ("Templeton") have been retained under investment subadvisory
agreements to provide investment advice and, in general, to conduct the
management investment program of the Growth and Income Stock Fund and the
International Equity Fund, respectively. Of the amounts received from the Growth
and Income Stock Fund, NMIS pays J.P. Morgan 0.45% on the first $100 million of
the combined net assets for all funds managed for Northwestern Mutual by J.P.
Morgan, 0.40% on the next $100 million, 0.35% on the next $200 million and 0.30%
on the combined net assets in excess of $400 million. Of the amounts received
from the International Equity Fund, NMIS pays Templeton 0.50% on the first $100
million of the combined net assets for all funds managed for Northwestern Mutual
by Templeton and 0.40% on the combined net assets in excess of $100 million.

Robert W. Baird & Co. Incorporated ("Baird") serves as the Distributor of the
Funds. Baird is an affiliate of Northwestern Mutual and NMIS. The Funds have a
12b-1 distribution plan and shareholder services agreement with Baird pursuant
to which a 0.35% and a 1.00% annual fee for Class A and Class B, respectively,
is calculated based on daily net assets.

The 0.35% fee for Class A is comprised of a 0.25% shareholder servicing fee and
a 0.10% distribution fee paid to Baird for various distribution expenses. The
1.00% fee for Class B is comprised of a 0.25% shareholder servicing fee and a
0.75% distribution fee. Of the 1.00%, 0.35% is paid to Baird for distribution
expenses; the remaining 0.65% is paid to Northwestern Mutual for reimbursement
of commissions paid to agents.

Baird received $357,002 of dealer allowances, Northwestern Mutual received
$101,130 of underwriting concessions from Class A sales charges and Northwestern
Mutual received $6,428 of contingent deferred sales charges from Class B shares
for the twelve months ended March 31, 1998.

Each Fund also pays the administrator, Northwestern Mutual, a monthly fee at an
annual rate of 0.10% plus costs for pricing securities. This administration fee
is for services including recordkeeping, preparation of reports and fund
accounting (except for the International Equity Fund). For the International
Equity Fund, Northwestern Mutual waives a portion of its fee equal to the fund
accounting fee paid to Brown Brothers Harriman & Co.

In addition, each Fund pays transfer agent and custodian fees, outside
professional and auditing fees, registration fees, trademark fees,
organizational costs, insurance premiums, Directors' fees and expenses, and the
printing and mailing costs of sending reports and other information to existing
shareholders.

The Funds pay a portion of their custodian fees indirectly through expense
offset arrangements. Custodian fees are reduced for maintaining compensating
balances in non-interest bearing accounts. The Funds could have invested the
assets used to pay for the custodian fees, had the assets not been used in the
expense offset arrangements.

NMIS and affiliates have agreed to waive their fees and absorb certain other
operating expenses during the first year of operations to the extent necessary
so that Total Operating Expenses will not exceed the following amounts:

The Aggressive Growth Stock Fund and Asset Allocation Fund paid commissions on
Fund transactions to an affiliated broker in the amount of $990 and $63,
respectively, during the twelve months ended March 31, 1998.

NOTE 9
Each Fund intends to comply with the requirements of the Internal Revenue Code
necessary to qualify as a regulated investment company and to make the requisite
distributions of income and capital gains to its shareholders sufficient to
relieve it from all or substantially all federal income taxes. Accordingly, no
provisions have been made for federal taxes.

Taxable distributions from net investment income and realized capital gains in
the Funds 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 passive foreign
investment companies and deferred wash losses.

It is the policy of the Fund to reclassify the net effect of permanent
differences between book and taxable income to capital accounts on the
statements of assets and liabilities.

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 Aggressive Growth Stock Fund,
International Equity Fund, Growth Stock Fund, Growth and Income Stock Fund,
Index 500 Stock Fund, Asset Allocation Fund, High Yield Bond Fund, Municipal
Bond Fund and Select Bond Fund (constituting Mason Street Funds, Inc., hereafter
referred to as "the Funds") at March 31, 1998, the results of each of their
operations, the changes in each of their net assets and the financial highlights
for the period March 31, 1997 (commencement of operations) to March 31, 1998, in
conformity with generally accepted accounting principles.  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 audit.  We
conducted our audit of these financial statements in accordance with generally
accepted auditing standards 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
audit, which included confirmation of the securities at March 31, 1998 by
correspondence with the custodians and brokers and the application of
alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.
