                           MESSAGE FROM THE PRESIDENT


DEAR CONTRACT OWNER:

We are pleased to provide you with The Sierra Variable Trust Semi-Annual Report
for the six months ended June 30, 1997.

The past six months have seen a continuation of favorable economic trends. Low
unemployment, low inflation, and sustained consumer confidence were all factors
that created a positive environment for both stocks and bonds. Despite a
correction of nearly 10% in the Dow Jones Industrial Average (the Dow) in the
first quarter of 1997, many stock market indices including the Dow, Standard &
Poor's Composite Index of 500 Stocks (S&P 500), and the Nasdaq Composite Index
posted net returns well above average for the period.

The S&P 500 rose 20.61% for the six months, and on June 30, was up 104% since
December 31, 1994. Such rapid gains are unusual considering the stock market's
history. Over the last 70 years, the S&P 500 posted an average annual return of
10.8%. Since 1919, there have also been 47 years in which the market has fallen
10% or more from the previous year's highs. With the market showing signs of
volatility in early 1997, we continue to advise investors to maintain a
long-term perspective when making investment decisions, and to seek the
assistance of a qualified professional.

The pattern of mutual fund purchases and sales during the first half of 1997 may
suggest, however, that many investors' mutual fund investment decisions are
affected by short-term performance. When stock and bond markets fell sharply in
March 1997 net new cash flow into mutual funds fell 77.4% from February to
March, according to the Investment Company Institute. Net inflows into stock
mutual funds, while still positive in March, fell to their lowest level since
July 1996 while bond and income funds experienced a net outflow. Unfortunately,
investors who curtailed fund purchases or even exited the market during the
downturn in March missed out on the recovery and subsequent net gains during the
second quarter of 1997.

At Sierra, we strive to pursue long-term performance consistent with the stated
objectives of each fund, without exposing investors to excessive risks. We
believe that, over the long-term, mutual fund investors are best served by
applying the principles of asset allocation and diversification in constructing
a portfolio, by selecting funds that follow a disciplined investment approach,
and by staying the course through periods of uncertain markets. 


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

                                We believe that,
                               over the long term,
                          investors are best served by
                             applying the principles
                             of asset allocation and
                        diversification in building an 
                             investment portfolio.

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


As a fund family, Sierra has been recognized by independent research firms such
as Lipper Analytical Services for its solid, above-average returns overall. For
example, for the year ended June 30, 1997, the Sierra Variable Growth & Income
Fund was ranked 31st out of 96 funds, or in the top 35% of its Lipper Growth &
Income Funds category. Since inception (the 3-year period ended June 30), the
Fund ranked in the top half of its category, or 28th out of 57 funds.1

In evaluating fund performance, we encourage investors to look beyond
the short term, and especially, to assess the relative investment risks
different funds may represent. Your Investment Representative can provide
in-depth information about the risk and return profiles of The Sierra Variable
Trust, which include money market, fixed income, and domestic and international
stock funds.

For investors seeking an institutional approach to managing money and a
longer-term focus on balancing risk and return goals, Sierra Asset Management
(SAM) offers an answer: the convenience and flexibility of an actively managed,
professional asset allocation program. SAM continually monitors the markets and
allocates an investor's portfolio among various asset classes to take advantage
of changing market conditions and forecasts. Active asset allocation helps
investors reduce risk and earn returns substantially above inflation.

In our continuing efforts to enhance the SAM Program, we introduced the new
Sierra Asset Manager variable annuity in May of this year. Sierra Asset Manager
is the next generation of the SAM Program in Sierra Advantage. Like the original
SAM Program, Sierra Asset Manager continues to provide all the risk management
tools associated with diversification and asset allocation. However, it offers
additional benefits, such as lower investment minimums and a "stepped-up" death
benefit that protects an investor's family against market risk.

Variable investment options available through Sierra Asset Manager include five
asset allocation portfolios (the new Capital Growth, Growth, Balanced, Value and
Income Portfolios of The Sierra Variable Trust). A fixed rate account is also
offered. For more complete information, including charges and expenses, about
the new Sierra Asset Manager, please contact your Investment Representative to
obtain a prospectus. Please read it carefully before you invest or send money.

As we move into the 21st century, we at Sierra appreciate the confidence you
have placed in us and will continue to demonstrate our commitment to you through
product innovation and the pursuit of disciplined investment management
strategies. Thank you for choosing The Sierra Variable Trust.

Sincerely,

        /s/James H. Overholt

President

              THE SIX MONTHS IN REVIEW & OUR OUTLOOK FOR 1997-1998


A strong, though sometimes bumpy, market environment prevailed during the first
     half of 1997, with stock market indices posting double-digit gains and
           fixed-income investments also producing positive results.


                      STOCKS CONTINUE TO BREAK NEW RECORDS

With a growing economy and low inflation, the stock market continued to surge to
new heights. Over the six months ended June 30, 1997, large capitalization
stocks turned in the best performance, with the Standard & Poor's Composite
Index of 500 Stocks (S&P 500) up 20.61%. The S&P MidCap 400 returned 12.99%,
while small-cap stocks, represented by the Russell 2000 Index, returned 13.37%
over the same period.

Although overall gains were impressive, the U.S. stock market experienced
increased volatility during the period, with the S&P 500 falling nearly 10% in
early 1997. After generating only single-digit returns in 1996, the
international stock markets rebounded in 1997, with Morgan Stanley Capital
International's Europe, Australasia and Far East (EAFE) Index returning 11.21%
in U.S. Dollar terms for the six months ended June 30, 1997.

Emerging-market stocks also posted gains in the first half of 1997, returning
16.65% from January to June. Returns on international investments were tempered
by the strength of the U.S. Dollar against the Japanese Yen and many European
currencies. By early July 1997 the Dollar had risen to a six-year high against
the German Mark and a two-year high against the Japanese Yen./1/

                          BONDS POST POSITIVE RESULTS

In the first quarter of 1997, U.S. gross domestic product rose a stunning 4.9%,
creating renewed concerns about rising inflation. Bond prices fell in March in
anticipation of the Federal Reserve's 0.25% hike in short-term rates on March
25, pushing yields on long-term government bonds above 7%.

With a slowing economy and benign inflation in the second quarter of 1997, the
Federal Reserve did not raise interest rates further. The fixed-income markets
reacted strongly, rebounding to generate their highest returns since the fourth
quarter of 1995. For the six months ended June 30, long-term U.S. Treasury bonds
returned 2.17%, as measured by the Lehman Long Term T-Bond Index.

Investment-grade corporate bonds and mortgage-backed securities also performed
well for the period. According to the Lehman Mortgage-Backed Securities Index
and Lehman Corporate Investment Grade Index, corporate bonds returned 3.07%,
while mortgage-backed securities were one of the strongest performers among
fixed-income securities with a gain of 3.92%.

In the municipal bond market, yields on many health care related issues rose as
legislators continue to focus on reducing health care costs. The Lehman Brothers
Long Muni Bond Index posted a return of 3.20% through June 30, 1997.

                   MARKET SHOWS SIGNS OF INCREASED VOLATILITY

Continued economic growth and low inflation have led to strong performance in
both the stock and bond markets. At the same time, however, uncertainty over the
future direction of interest rates and sustainable

Stocks are represented by Russell 2000 Stock Index. International Stocks are

T-bills are generally considered the safest securities because they are
short-term and offer a fixed yield at maturity, which is guaranteed by the U.S.
Government. Government bonds are riskier than T-bills because of the longer
maturities, yet they are generally subject to less credit risk, because the
interest payments and return of principal are also backed by the U.S.
Government, if held to maturity. An investor would typically purchase stocks for
long-term growth of capital. However, stocks are often subject to significant
price fluctuations and therefore an investor may have a gain or loss in
principal when the shares are sold.

corporate earnings growth has produced higher market volatility. Bond prices
have fluctuated due to changing interest rates, and equities have also been
impacted. From March 11 to April 11, for example, the Dow Jones Industrial
Average dropped 9.8%, and many individual stocks experienced steeper drops.

These declines resulted in many mutual funds reporting negative returns for the
first quarter of 1997, before rebounding in May and June. According to Lipper
Analytical Services, which tracks mutual fund performance, the average equity
mutual fund lost 1.98% in value, the first quarterly decline since 1994.
Large-cap growth funds averaged a decline of 1.28%, while small-cap stock funds
fell 6.91% on average in the first quarter.

Individuals who began investing only in the last few years may find the market
ups and downs disconcerting because the volatility of the stock market has been
unusually low in recent years. From January 1991 through December 1996, the S&P
500 rose or fell more than 1% in a single day on average about once every eight
trading days. In the first six months of 1997, a 1% move has occurred once every
three trading days, on average. The chart below shows, however, that the
market's current volatility is more in line with its longer-term averages. The
period from 1990 to 1996 was an exceptionally quiet one compared to previous
periods.

                                   MANAGE RISK

Maintaining a diversified, well-allocated portfolio of investment assets can
help investors weather periods of market turbulence. 

Asset allocation refers to the way in which your portfolio is divided among
different asset categories, which may include money market, fixed income, and
stock investments. An effective asset allocation strategy reflects your personal
financial circumstances, such as your investment time horizon, need for current
income versus long-term growth, and your tolerance for short-term market
fluctuations. You can further diversify your portfolio by investing in a variety
of investment subcategories. For example, the stock portion of your portfolio
may be diversified among stocks of small, medium, and large companies.

The strong performance of the U.S. stock market since 1994 means that your
investment portfolio may have a higher allocation in stocks than you

originally intended. Fixed-income investments such as bonds and bond funds can
help reduce variability in portfolio returns. While stocks have historically
provided higher returns over time and therefore can add important growth
potential to your portfolio, bonds can provide steady income even as market
values fluctuate. In addition, bond prices can move independently from stock
prices over time, helping to reduce investment risk.

For example, the graph below compares the highest and lowest annual returns for
stocks and a diversified portfolio of stocks and bonds over the last 25 years.
While the range of returns for a portfolio of 100% stocks varied from 37% to
- -26%, the variation was only 31% to -8% in a diversified portfolio. In other
words, during this period, a diversified portfolio captured much of the upside
potential of stocks, but with dramatically less downside risk. Of course, past
performance is not a guarantee of future results.

Including international investments can also help smooth out fluctuations in
portfolio returns, since domestic and international stock markets tend to move
out of synch over various periods. International securities can pose higher
currency and liquidity risks relative to domestic issues. However, higher risks
can produce higher returns. Over the twenty years ended December 31, 1996, a
portfolio allocated 80% to the S&P 500 and 20% to international stocks
represented by the EAFE index earned slightly higher returns with less
variability than a portfolio allocated 100% to the S&P 500. Of course, past
performance does not guarantee future results.

                   THE SIERRA ASSET MANAGEMENT (SAM) SOLUTION

Building an asset allocation strategy that meets investor needs and their
specific risk and return goals requires careful planning and knowledge of the
financial markets. As an investor, you may not have the time or energy to keep
track of the markets and actively manage your investments. Sierra specializes in
active investment management. Our dedication to research, plus our focus on
diversification and asset allocation to help investors control risk, are the
core elements of Sierra's investment philosophy.

For effective asset allocation and risk management, Sierra offers a choice of
Sierra Asset Management (SAM) investments. The SAM Program in the Sierra
Advantage Variable Annuity provides asset allocation strategies designed to help
you control risk and achieve returns substantially above inflation.

In our continuing efforts to enhance the SAM Program, Sierra has recently
introduced five new asset allocation portfolios in The Sierra Variable Trust:
Capital Growth Portfolio, Growth Portfolio, Balanced Portfolio, Value Portfolio,
and Income Portfolio. These Portfolios are available as investment options in a
new variable annuity called Sierra Asset Manager.

                  THE NEW SIERRA ASSET MANAGER VARIABLE ANNUITY

Launched in May of this year, the Sierra Asset Manager Variable Annuity is the
next generation of the Sierra Asset Management (SAM) Program. In addition to
providing active asset allocation and risk management, Sierra Asset Manager is
one of the first variable annuities that takes advantage of the "fund of funds"
concept. This unique structure makes Sierra Asset Manager easier to maintain
than the SAM Program in Sierra Advantage and offers greater operating
efficiencies.

Like the original SAM Program, the Sierra Asset Manager offers actively managed
diversification, with a focus on regular portfolio monitoring and

                              OUTLOOK FOR 1997-1998

Looking ahead, we expect economic growth to continue slowing to a more healthy,
sustainable level, while inflation pressures moderate. In recent months, the
Federal Reserve has taken a more neutral approach to interest rates, allowing
the markets to dictate their current levels. Interest rates should remain
relatively stable if growth does not rebound significantly and if inflation
remains benign. Recent inflation reports suggest that this trend should
continue, as the Consumer Price Index has been rising only moderately, while the
Producer Price Index has actually been falling so far in 1997.

Another component of inflation, which is closely watched by the Federal Reserve,
is the Employment Cost Index, which on average represents two-thirds of the
final cost of a product. There has been concern that the current economy is
heading towards full employment which will force manufacturers to raise wages
and subsequently prices, as they compete for skilled workers. Recent reports,
however, suggest that wage pressures remain under control. Slowing has become
evident in the manufacturing sector as new orders for durable goods have
recently tapered off. In addition, strong retail sales witnessed in the first
quarter of 1997 have somewhat slowed, demonstrating the unwillingness of
consumers to pay higher prices for goods and services in what is currently a
very competitive environment.

Furthermore, the strength of the U.S. Dollar and productivity gains experienced
by U.S. corporations have also helped to hold down prices and production costs.
These factors all point to a continuation of the currently low inflation
environment and have led to suggestions by Federal Reserve Chairman Alan
Greenspan that an interest rate increase may not be necessary over the near
term.

The markets have performed well in response to current economic conditions.
Since early 1997, bond yields have dropped and equity markets have rallied back
to new highs. Given the favorable economic outlook, we remain positive on both
bonds and stocks. Overseas, there has been continued strength in core Europe and
selected emerging-market countries. Global bond prices have been strengthening,
reflecting the view that worldwide inflation should remain benign. Of course,
while our overall outlook for the financial markets is decidedly positive, we
continue to believe that, regardless of any outlook, risk and risk control
should always remain an important consideration when making investment
decisions.

Outlook Summary: 

 . Continued economic growth, but at a slower, more sustainable rate than in the
  first quarter of 1997

 . Continued low levels of worldwide inflation

 . Positive outlook for equity markets, although volatility seen in the first
  half of 1997 may continue

 . Positive outlook for fixed-income investments as interest rates should remain
  relatively steady or fall with slow growth and benign inflation

the Sierra Asset Manager, such as the fact that the investment return and
principal value will fluctuate, that liquidity may be limited by surrender
charges and tax penalties if withdrawn before the age of 59 1/2, and that
insurance-related fees and charges may affect the annuity performance.

Understanding the Enclosed Charts

In order to help you understand The Sierra Variable Trust's investment
performance, we have included the following discussions along with graphs that
compare the Funds' performance with certain market indices. Descriptions of
these indices are provided next to the individual graphs on the following pages.

Generally, an index represents the market value of an unmanaged group
of securities, regarded by investors as representative of a particular market.
An index does not reflect any asset-based charges for investment management or
other expenses. The total returns shown for the Funds are not an estimate or
guarantee of future performance and do not take into account charges at the
annuity and separate account level.

The total returns of the Funds reflect Sierra Advisors' and Sierra Fund
Administration Corporation's ("Sierra Administration") voluntary waiver of fees,
Sierra Advisors' absorption of certain expenses, and Credits allowed by the
Custodian. Total returns would have been lower if these fees and expenses had
not been waived, absorbed, or reduced by credits.

Both the Funds' performance results and the market indices reflect total
reinvestment of income, dividends, and capital gains. The unit values of these
variable options will fluctuate with market conditions.

Yield indicates the investment income per share as a percentage of the offering
price, whereas total return includes both net investment income and changes in
the value of the shares as a percentage of the initial investment. The 30-day
SEC yield is the yield calculated pursuant to a standard formula required by the
Securities and Exchange Commission ("SEC") for performance advertisement
purposes, and does not imply any endorsement or recommendation by the SEC.

PORTFOLIO MANAGER:
SCUDDER, STEVENS & CLARK, INC.

[PICTURE OF THOMAS M. POOR APPEARS HERE]

Mr. Poor, Managing Director of Scudder, is the portfolio manager for the Short
Term High Quality Bond Fund. He is a Chartered Financial Analyst and has been
with Scudder since 1970. Mr. Poor has had primary investment management
responsibility for the Fund since its inception.

PERFORMANCE REVIEW:

From the Fund's inception (January 12, 1994) through June 30, 1997, the Short
Term High Quality Bond Fund's average annual total return advanced 3.94%. For
the 12-month period ended June 30, 1997, the Fund's total return was 5.89%. The
Fund's 30-day SEC yield as of June 30, 1997, was 5.76%. For additional
information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

The most significant factors contributing to the Fund's performance over the
past six months were the generation of income into the Fund and the strong
performance of the Fund's corporate and mortgage-backed holdings. Over the last
six months, interest rates rose slightly, but a rally in the second quarter
reversed what started out to be another lackluster year in bond markets. While
volatility continues to be present, our focus on income has enabled the Fund to
generate positive total returns over the last six months.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

Over the last six months, the U.S. bond market has continued to exhibit
volatility, albeit within a fairly tight trading range. On December 31, 1996,
the yield on the 30-year Treasury Bond was 6.64%; the six-month period ended
with a 6.78% yield. The 14 basis point increase in rates masked the positive
returns experienced in the quarter, as well as the confidence created by a
strong June. Conflicting economic statistics made it tough to determine the
magnitude of the economy's growth and structure duration appropriately. As such,
we held the Fund's duration within a fairly tight range--reflecting uncertainty
regarding the direction of interest rates.

Despite the fluctuation of interest rates over the last 12 months, the Fund has
benefited from sizable positions in high-income producing corporate bonds,
asset-backed securities and mortgages. Yield advantages have helped to provide
positive returns in all of these categories.

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

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

There were no major shifts in portfolio holdings that significantly impacted
performance. However, we should note the performance of various sectors.
Corporates, mortgages, and asset-backed securities were important components of
the Fund's portfolio construction. Over the past 12 months, these sectors
performed very well relative to Treasuries. The best performing sector was
mortgages, largely due to strong price performance and high yields. The Fund's
holdings in this sector increased in both value and overall portfolio weighting.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

Given the current economic outlook, we expect strength in the bond market to
continue. Should growth be stronger than expected, we will most likely see a
resurgence of inflation concerns. With this uncertainty over the intermediate
term, the Fund's duration should remain at slightly below two years.

Looking forward, we expect continued growth in the economy but have concerns
regarding how long this expansion can last, especially with little or no
inflation. Potential credit excesses, profit disappointments, and the
unpredictability of foreign capital flows may all have a negative impact on the
bond market. However, over the long run, we continue to believe that
fixed-income investors will be rewarded in terms of both income and total
returns.

PORTFOLIO MANAGER:
SCUDDER, STEVENS & CLARK, INC.

[PICTURE OF ADAM M. GRESHIN APPEARS HERE]

Mr. Greshin is the lead portfolio manager for the Short Term Global Government
Fund. Mr. Greshin joined Scudder in 1986 as an international bond analyst.
Currently, he is Product Leader for Scudder's global and international
fixed-income investing. He was involved in the original design of the Fund and
has served as a member of the Fund's portfolio management team since 1993. Mr.
Greshin assumed responsibility for the Fund's day-to-day management and
investment strategies effective November 1995.

PERFORMANCE REVIEW:

From the Fund's inception (May 12, 1993) through June 30, 1997, the Short Term
Global Government Fund's average annual total return was 3.98%. For the 12-month
period ended June 30, 1997, the Fund's total return was 8.25%. The Fund's 30-day
SEC yield as of June 30, 1997, was 4.92%. For additional information, see the
accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

Global bond prices increased overall for the period ended June 30, 1997. During
the first half of 1997, bond prices exhibited notable price swings, due in part
to anticipation of central bank activity. Despite interest rate increases by the
U.S., Canada, and the United Kingdom so far this year, investors did not appear
to be overly concerned with those short-term rate hikes. Weak growth in Europe
allowed for rate reductions in Spain, France and Italy.

The U.S. Dollar strengthened significantly during the period, rising 10.99%
against the German Mark and 10.90% versus the French Franc. Factors contributing
to the Dollar's rise included the increased probability of further short-term
rate increases in the U.S., strengthening U.S. equity markets leading to a
demand for U.S. Dollars by overseas investors, and rate cuts in other developed
countries, causing weakness in their underlying currencies.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The primary driving force behind the strength in bond prices during the period
was low inflation, subdued economic activity, and increased demand from the
world's main sources of capital in search of yield. The main beneficiaries were
the higher yielding bond markets of Spain, Italy, Australia and the United
Kingdom. However, the Fund remained well diversified geographically in European
countries to reduce risk of over-concentration in any single country. In
addition, European bond positions

were largely hedged into U.S. Dollars to protect against European currency
weakness (or strength in U.S. Dollars versus those currencies) which would have
the effect of offsetting local market gains. The Fund's exposure to European
bonds remains significant in light of the weak economic recovery there
- --providing liquidity, yield and the potential for gains from active currency
management.

The Fund continued to be well diversified between the U.S. and the dollar-bloc
markets of Australia, Canada and New Zealand. This provided higher income
potential and required only limited currency hedging due to high correlations
with the U.S. Dollar. While growth is higher in the dollar-bloc countries,
inflation remains subdued and investors have not yet fully recognized the
excellent valuations offered by these markets.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/ SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

We redeployed proceeds from core European holdings in Germany and the
Netherlands and placed them in short-term emerging market positions. These
assets provided additional yield and diversification in addition to the relative
stability of their underlying currencies. Returns from emerging market bonds
have been very favorable, as investors expand their search for yield, and
favorable fundamental changes in emerging economies lead to improved credit
quality. Low price correlations of emerging market bonds with developed country
bond markets provide additional long-term stability without altering the
risk/reward characteristics of the Fund.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

We are concerned that any further rate increases will dampen enthusiasm for
bonds around the world, given the recent rate increases in the U.S., Canada, and
the U.K. Continued strength of the U.S. Dollar seems likely due to expected
further increases in U.S. interest rates. The majority of the Fund's foreign
positions is hedged into U.S. Dollars to manage risk.

We will continue to overweight the dollar-bloc bond markets where we find
excellent valuations. In Europe, we will also continue to monitor the major
currencies, particularly the Deutschemark, whose recent weakness may continue.
By 1998 we should see signs of a recovery in Europe and Japan, potentially
exerting upward pressure on global bond yields.

Overall, we expect the strong performance of the Fund to continue, as past
results support our ability to manage currency risk and/or local market trends,
while identifying attractive investment opportunities worldwide.

The day-to-day management of the U.S. Government Fund's portfolio is the
responsibility of a committee composed of individuals who are officers of
BlackRock. This committee has managed the Fund since December, 1994, and is
supervised by Keith Anderson and Andrew J. Phillips. Mr. Anderson, a Managing
Director of BlackRock, has been co-head of the Portfolio Management Group since
1988. Mr. Phillips has been a portfolio manager of BlackRock since 1991 and a
Principal of BlackRock since 1996. 

PERFORMANCE REVIEW:

From the Fund's inception (May 6, 1993) through June 30, 1997, the U.S.
Government Fund's average annual total return was 4.99%. For the 12-month period
ended June 30, 1997, the Fund's total return was 8.12%. The Fund's 30-day SEC
yield as of June 30, 1997, was 6.58%. For additional information, see the
accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

The Fund's weighting in mortgage-backed securities and a generally favorable
economic environment contributed most significantly to the Fund's performance
over the last period.

The market for mortgage-backed securities (MBS) significantly out-performed the
broader investment-grade bond market for the six months ended June 30, 1997.
Investors sought higher-yielding fixed-income securities and subsequently
boosted prices in the mortgage sector. For the period, the MBS market as
measured by the Lehman Brothers Mortgage Index posted a 3.92% total return
versus the 3.11% return of the Lehman Brothers Aggregate Index.

A slowing economy, favorable statistics, and generally stable interest rates in
the second half of 1996 contributed to positive performance of the Fund.
However, stronger economic data and accompanying inflation fears caused U.S.
Treasury yields to rise in early 1997, causing temporary weakness in the bond
markets overall. Although inflationary measures such as commodity, producer, and
consumer prices remained relatively stable, labor markets continued to
strengthen. After expanding at a blistering pace of 4.9% during the first
quarter, the U.S. economy's growth rate slowed to a more moderate 2% to 2.5%
during the second quarter of 1997, allowing interest rates to decline and bond
markets to rally.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The Fund's strong total return performance was primarily a result of the Fund's
duration and mortgage-backed security (MBS) holdings. The Fund consistently held
approximately 50% of assets in mortgage pass-throughs, ending the period with
45% in the sector. Additionally, the Fund's stake in collateralized mortgage
obligations (CMOs) and adjustable-rate mortgages (ARMs) increased the Fund's
overall mortgage exposure, enhancing performance versus Treasuries. Over the
period, the Fund sold its entire ARM position in response to the strong price
performance and tighter yield spreads of these securities.

The Fund's duration, or price sensitivity to interest rate movements, was
continually adjusted to reflect our outlook for interest rate trends. The Fund
ended the period with a neutral duration, which reflects our cautiously
optimistic view of interest rates and the domestic bond market.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/ SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

The Fund reduced its mortgage pass-through exposure and sold its ARM holdings
towards the end of the period. In addition, the Fund eliminated its exposure to
10- and 20-year Small Business Administration Loans (SBAs). The cash raised by
the sale of these securities was primarily invested in non-agency CMOs, which
helped the Fund meet the annuity asset requirements as stated in rule 817(h)
(which allows the Trust's shareholders to retain their tax-deferred status).
Specifically, the Fund purchased a private label CMO backed by loans that carry
the full faith and credit of the U.S. Government.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

In our view, the Federal Reserve has managed to achieve a soft landing for the
economy. The economy's growth rate seems to be sustainable, and although data
points towards an economic slowdown, consumer confidence numbers reached a
28-year high at the end of June. As a result, we expect the Fund to maintain its
neutral duration stance. However, we believe consumer spending may increase
during the second half of the year, and the tight labor market may exert wage
pressures on the economy. If this should occur, we may shorten the duration due
to the potential for inflationary pressures to reappear and cause interest rates
to begin rising. The Fund will also seek opportunities to re-enter the mortgage
market should prices fall in response to escalating prepayments caused by
currently lower mortgage rates.

PORTFOLIO MANAGER:
TCW FUNDS MANAGEMENT, INC.

[PICTURE OF JAMES M. GOLDBERG APPEARS HERE]

Mr. Goldberg, a Chartered Financial Analyst and Chartered Investment Counselor,
has been Managing Director of TCW Management since 1989 and Managing Director of
the Trust Company of the West, the parent corporation of TCW Management, since
1984. He has had primary portfolio management responsibility for the Corporate
Income Fund since its inception.

PERFORMANCE REVIEW:

From the Fund's inception (May 7, 1993) through June 30, 1997, the Corporate
Income Fund's average annual total return was 5.57%. For the 12-month period
ended June 30, 1997, the Fund advanced 8.33% on a total return basis. The
Corporate Income Fund's 30-day SEC yield as of June 30, 1997, was 6.68%.For
additional information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

The most significant factor contributing to performance over the past six months
was the Fund's longer duration, relative to its benchmark index. The improving
credit quality of issues held by the Fund was also a factor.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

Over the past year, interest rate volatility had a major impact on Fund
performance. During the period, 10-year Treasury Bond yields experienced an
overall increase of 8 basis points -- ending the period at 6.49% versus 6.41% in
December of 1996. The bellwether 30-year U.S. Treasury Bond yield increased 14
basis points during the same period, rising to 6.78% in June of 1997 versus
6.64% in December of 1996. Improving corporate profitability and benign
inflation also positively affected the Fund's performance. Due to the long-term
nature of the Fund's investment objectives, maturity and duration were
maintained throughout the period and allowed the Fund to participate in the
overall market strength.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

There were no major shifts in the Fund's holdings, and none of the minor changes
had a significant impact on Fund performance. The Fund decreased its exposure to
industrial issues during the period, reflecting the sale or reduction of Amax
Inc., Boise Cascade Corporation, Georgia-Pacific Corporation, International
Paper Company, and Mead Corporation. Also during the period, the Fund purchased
a position in Norfolk Southern Corporation, and holdings in the financial sector
varied somewhat as a result of our purchase of Hartford Life Insurance Company,
as well as the sale of Dean Witter, Discover & Company.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

Overall, our outlook is positive.  We forecast corporate profitability to be
reasonably maintained in the near future, and a benign inflation environment to
persist. Although corporate bond spreads are at historically tight levels, as
compared to U.S. Treasuries, demand for corporate product remains strong among
investors with new issues easily absorbed by the market.

After posting spectacularly high growth rates from the end of 1996 through early
1997, we expect Gross Domestic Product (GDP) growth to slow to an average of
2.0% to 2.5% for the next 12 months. Despite this slowdown, we anticipate a
modest reacceleration later in 1997 and expect a slight increase in the Federal
Funds rate prior to year-end. We continue to believe that risk remains for
short-term interest rates to increase. However, if the economy proceeds exactly
as forecast, or actually grows below trend, a Fed increase is unlikely. Only a
below-trend GDP growth rate over the next few quarters is likely to produce
further declines in short or intermediate rates.

PERFORMANCE REVIEW:

From the Fund's inception (January 12, 1994) through June 30, 1997, the Growth
and Income Fund advanced 19.67% on an average annual total return basis. For the
12-month period ended June 30, 1997, the Fund's total return was 31.15%. For
additional information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

The stock market continued its record-setting pace in 1997, with the S&P 500
gaining over 20% year to date. Net of fees, the Fund also posted high returns,
outperforming the Lipper Variable Annuity Growth & Income Average by nearly 180
basis points. The most significant factors contributing to the Fund's
performance were stock selection and solid corporate earnings growth.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The Fund benefited from the U.S. stock market's impressive gains over the last
two quarters. According to Lipper Analytical Services, Inc., the second quarter
of 1997 was the best quarter for U.S. stock-fund performance since 1991. The
environment in the last half of 1996 centered around strong corporate profits
and weaker economic data, which helped alleviate inflation and interest rate
fears. Market volatility increased in March 1997 as investors feared rising
interest rates. In response, we slightly underweighted interest rate sensitive
sectors--specifically, finance, telephone, utility and insurance sectors--as
compared to the benchmark. However, in the second quarter as interest rates
steadied, these sectors rebounded, and

we readjusted our weightings to a more neutral stance while concentrating on
stock selection.

This strategy, combined with identifying undervalued stocks that are
fundamentally attractive for the long term, contributed to the Fund's strong
six-month return.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/ SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

Over the past six months, we focused on individual stock selection and held a
highly diversified portfolio of value stocks. The Fund's best performing sectors
included telephone, drugs, basic industry, retail, and transportation. Warner
Lambert Company contributed most positively to performance, gaining 67.1% in the
first half of 1997. The company benefited from FDA approvals of two new drugs.
In retail, we bought on sector weakness, and the Fund profited as retail
rebounded--evidenced by

Wal-Mart Stores Inc. returning 49.3% in the first six months of 1997, and
Toys R Us Inc. gaining 25% in the last quarter alone.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

Our economic outlook calls for strong growth in 1997 (GDP +3.5%) and below trend
growth in 1998 (GDP +1.75%). Inflation will pick up above 3% in 1998, and the
low unemployment rate of 4.8% will impact wage growth and eventually spill over
to the general inflation rate. We expect corporate profit growth of 10% in 1997
and 4% in 1998, showing a strong correlation with economic growth.

In order to manage the Fund in this environment, we will continue to focus on
finding attractive stocks rather than attempting the risky practice of market
timing. As such, the Fund will be fully invested in a diverse selection of
stocks and remain sector neutral. On a sector basis, we have positioned our
technology holdings away from the PC industry and towards the data networking
areas. We believe the environment in these two subsectors is about to
reverse--with the PC industry slowing due to a lack of significant new products.

On the other hand, data networking companies plan to release a number of new
products to assist corporations with intranet capabilities and upgrade
communication equipment.

PORTFOLIO MANAGER:
JANUS CAPITAL CORPORATION

[PICTURE OF WARREN B. LAMMERT APPEARS HERE]

Mr. Lammert is a graduate of Yale University and the London School of Economics.
He first joined Janus in January 1987 and has been portfolio manager for the
Growth Fund since its inception. He is a Chartered Financial Analyst.

PERFORMANCE REVIEW:

From the Fund's inception (May 7, 1993) through June 30, 1997, the Growth Fund
advanced 17.30% on an average annual total return basis. For the 12-month period
ended June 30, 1997, the Fund's total return was 11.47%. For additional
information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

For the past year, the stock market has put up very impressive numbers. With
increased investor focus on large-cap stocks, the S&P 500 Index gained 34.70%.
In this environment, the Fund returned 11.47%. While the market's breadth has
improved somewhat, large-capitalization stocks continued to lead their smaller
siblings. The Fund's concentration in mid- and small-cap stocks hurt performance
somewhat, as compared to the stellar returns of the S&P 500.

Although the first quarter of 1997 proved to be a difficult period for the Fund,
we are pleased with its most recent performance. The Fund gained some momentum
and made up for its previous performance, as many stocks we held bounced back
nicely. While we remain somewhat concerned that the economy's underlying
strength may push up interest rates, our research efforts have successfully
uncovered compelling, individual ideas.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

The large-stock indices continued to be tough competitors for active managers. A
growing trend toward indexing served to bolster the stocks that comprise the S&P
500 Index. New money continued to chase returns, and the "hot" sector of the
market was the large, liquid stocks of the major market indices. Although small-
to mid-sized stocks rallied back to new records, larger stocks maintained their
impressive lead in performance, and have dominated domestic equities during the
reporting period. In fact, when the second quarter began, the dichotomy in
returns between large and small stocks had reached its highest point since 1937,
reflecting investor's affinity for large, liquid companies.

In addition, "value" stocks outperformed growth stocks in small-, mid-, and
large-cap stock categories. Value stocks are categorized as those issued by
companies with stock prices considered below market value. They have the
potential to increase their value based on market perception--not increased
growth. Historically within both the large- and small-cap asset sectors, value
and growth stocks have performed consistently in line with each other. However,
during this reporting period, there was greater divergence in their performance
than during any other period in history. Despite this gap, May and June
witnessed a recovery by growth stocks, and--due to their cyclical nature --we
expect them to more closely track value stock performance for the rest of 1997.
Clearly, the Fund missed out on significant short-term gains in both the
large-cap and value stock sectors.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/ SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

The portfolio is somewhat more varied than in the past, but several broad themes
still exist. These include health care and pharmaceuticals, technology and
telecommunications, financial services, and selected retail and consumer
products companies.

Among our drug and health care holdings, Warner Lambert Company had an excellent
second quarter, up over 43%. We also own Rhone-Poulenc Rorer Inc., which gained
some 23% this quarter. Finally, Sofamor Danek Group, Inc., a maker of surgical
spinal implants, also increased in value. The company's products are capturing
market share and it is bringing new products to market at a faster clip due to
streamlined approval procedures at the U.S. Food and Drug Administration.

On the technology front, we did well with a wide variety of stocks, from
equipment manufacturers Cisco Systems, Inc. and Lucent Technologies, Inc., to
software developers Wind River Systems and Aspen Technology, Inc., to PC
retailer Compaq Computer Corporation. Among our financial stocks, UNUM
Corporation and Associates First Capital Corporation posted good performance. We
also continue to own a number of small thrifts, such as Rosyln Bancorp, Inc.,
Ambanc Holdings Company, Inc., and Provident Financial Holdings, Inc. Finally,
we cut Wells Fargo & Company at a significant profit after the integration of
First Interstate proved more problematic than expected.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

Although we have trimmed positions that were fully priced or out of alignment
with previous earnings estimates, our commitment to exceptional earnings
potential has not wavered. This discipline served us well recently, and we
believe it will continue to serve us well going forward. Much of our concern
during 1997 has been that economic growth would pick up and interest rates would
have to move higher. However, low levels of inflation have helped to maintain a
positive environment for interest rates and corporate profitability. Given this
positive economic backdrop, the Fund should continue to be an attractive
investment for growth investors.

Mr. Goff has a degree from Yale University, and is a Chartered Financial

PERFORMANCE REVIEW:

From the Fund's inception (January 12, 1994) through June 30, 1997, the Emerging
Growth Fund advanced 13.84% on an average annual total return basis. For the
12-month period ended June 30, 1997, the Fund's total return was -0.82%. For
additional information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

Stocks continued to post strong gains throughout the six-month period, and the
indices remain at or near record levels. However, large capitalization stocks
have paced the market's returns, and small- to mid-sized stocks continued to
trail the overall market. During the period, the S&P 500 Index gained 20.61%,
and the Standard & Poor's MidCap 400 Index was up 13.04%. Meanwhile, the Sierra
Emerging Growth Fund gained 3.29%.

Despite a strong rebound by the small- and mid-cap sectors in the second quarter
of 1997, the Fund continued to underperform the overall market.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

For over a year, a major market dichotomy has persisted, with large
capitalization stocks dominating smaller issues. At one point early in the
second quarter, the disparity in performance was the largest we have seen since
1937. A number of factors have contributed to this large-cap stock dominance,
including a long stretch of above-average corporate earnings, an affinity among
investors for liquidity, and "hot" money chasing a limited number of stocks.

Another trend in the market was that of value stocks outperforming their growth
stock counterparts. Companies with stock prices considered below market value
are called value stocks, as they

have the potential to increase their value based on market perception--not
increased growth. Historically, value and growth stocks have performed
consistently in line with each other, within both the large- and small-cap asset
sectors. However, during this reporting period, there was a far greater
divergence in their performance than during any other period in history. Despite
this gap, May and June witnessed a recovery by growth stocks, and--due to their
cyclical nature--we expect them to more closely track value stock performance
for the rest of 1997.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

Consistent with the Fund's investment strategy to identify emerging companies
with high-growth potential, the Fund owned a number of stocks that gained over
35% in the second quarter. These included Fastenal Company, Papa John's
International Inc., Premier Parks, Inc., Omnicare Inc., and the Apollo Group
Inc. Our research efforts continued to generate new investment ideas, and we
added positions in the media industry, including Clear Channel Communication,
Evergreen Media Corporation, Outdoor Systems Inc., Heftel Broadcasting
Corporation, and Univision Communications, Inc.

Even though the Fund registered strong gains across a broad spectrum of
holdings, we did experience some mild disappointments. Both HFS, Inc. and
Insignia Financial Group, Inc., which have been great performers, were basically
unchanged. In both cases, we remain positive about the companies' prospects, and
therefore maintain the positions.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

Although the Fund recorded good results in the second quarter relative to the
Index, investors are only beginning to be rewarded for their patience, and have
yet to be paid for the Fund's full potential.

While the fundamentals for the stock market and the economy appear intact, we
remain squarely focused on individual stock selection. We continue to search for
companies that can grow their earnings in any environment. Ultimately, stock
prices will follow superior earnings growth. We remain enthusiastic about the
current Fund's prospects, and continue to search for compelling investment ideas
where our research can add value.

PERFORMANCE REVIEW:

From the Fund's inception (May 7, 1993) through June 30, 1997, the International
Growth Fund's average annual total return was 10.57%. For the 12-month period
ended June 30, 1997, the Fund's total return was 16.28%. For the same time
period, the Fund significantly outperformed the benchmark Morgan Stanley Capital
International EAFE Index which advanced 12.84% on an average annual total return
basis.* For additional information, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE SIX-MONTH PERIOD ENDED JUNE 30, 1997?

The first three months of 1997 saw mixed performance for foreign stock markets.
Most European markets advanced in local-currency terms, though the strong U.S.
currency tempered those gains in dollar terms. Japan's equity market struggled,
hurt by ongoing concerns over the banking sector and the potential impact higher
taxes might have on Japan's economic recovery. Among emerging markets, the most
noteworthy performance belonged to Latin America--led by Brazil, whose market
rose over 25%.

During the second quarter of 1997, the turnaround in Japan's broad-market
averages reflected renewed bullishness for its economic prospects, as well as
favorable reaction to the government's deregulatory efforts and developments at
the corporate level. In all cases, this optimism appears justified. Japan's
economy grew at an annualized rate of 6.6% in the first quarter, well above
expectations.

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

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

As 1997 opened, the strength of the U.S. Dollar tempered gains in European
markets, and Japan's market struggled. Latin American markets rose, led by
Brazil's 25% increase in both local-currency and dollar terms. This performance
continued into the second quarter as optimism for progress continued to drive
Latin American equities. European markets also flourished in the second quarter
and Asian-Pacific markets were led by a strong recovery in Japan.

Throughout the period, the Fund continued to use a consistent bottom- up process
of evaluating companies while maintaining a top-down view of economies and
regions. The Fund also continued to look for value on a longer-term basis.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

During the first quarter 1997, we trimmed the Fund's weightings in the
peripheral European markets, specifically Spain and Portugal. Spain rallied with
the decline in bond yields, but with our holdings approaching their target
prices, and given the increased potential for a delay in the launch of monetary
union, we decided to take some profits and redeploy those assets elsewhere.

We continue to find good opportunities in the U.K. and have increased the Fund's
weighting there. We reduced our Japanese exposure to 17% as of the end of March,
taking profits on stocks that had met our target prices. We increased the Fund's
weighting in Brazil in recent months. This has worked to the Fund's advantage
year to date, as the market has been the region's strongest performer.

By country, the Fund's largest weighting was the U.K., which performed
particularly well in U.S. Dollar terms due to the strengthening British Pound.
The Fund's largest weighting in continental Europe during the quarter remained
France, which continued to perform well.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

We feel that European holdings will continue to perform well. Germany has
performed particularly well for the Fund, motivating us to increase its
exposure. British companies have enjoyed strong profit growth in recent
quarters, and we remain underweighted in the U.K. We continue to view our
holdings in the Spanish market favorably, as they have benefited from the
decline in bond yields. Australian stocks have grown increasingly positive given
the tangible signs of a recovery in corporate earnings. We are optimistic about
South Korea--currently one of the cheapest markets in the world--as its economy
has been sufficiently discounted. We are encouraged by the earnings outlook for
many Hong Kong companies in 1997, and are keeping a close watch on stock
valuations. In Japan, our own estimate calls for a higher growth rate and
continued expansion in corporate earnings. This combination should lead to a
turnaround in investor sentiment and a recovery in overall market performance.

We believe non-U.S. equities will continue to provide excellent long-term
growth opportunities. That said, we will continue to research those companies we
feel may provide long-term growth. We continue to find value in many markets,
and believe 1997 stands to be a very rewarding year for international investors.

Goal & Objective

The Capital Growth Portfolio ("Portfolio") is designed to help manage investment
risk and achieve its objective of long-term capital appreciation. The Portfolio
allocates its assets strategically among mutual fund subaccounts in The Sierra
Variable Trust family. The Portfolio is managed similarly to the Sierra Asset
Management (SAM) Program Aggressive Growth Strategy, whose goal was to produce
an average annual return that exceeds the S&P 500 over a period of six years or
longer. Over short-term periods, however, significant differences may exist
between the Portfolio and the S&P 500.(1)

Current Allocation

The Capital Growth Portfolio is positioned to take advantage of the favorable
economic and market environments by remaining 85% invested in equities. The
Portfolio is well-diversified, holding four Sierra Variable Trust equity funds:
Growth and Income, Growth, Emerging Growth, International Growth. The positions
in cash equivalent and short-term bonds also aid in risk management. The six
funds represent nine major asset classes. Allocations between these funds, and
therefore the different asset classes, allow the Portfolio to manage risk while
producing capital appreciation.

More specifically, the Portfolio's current investment strategy is to:

 . Enhance prospects for capital appreciation by maintaining a broadly
  diversified mix of equities favoring the core holdings found in The Sierra
  Variable Trust Growth and Growth & Income Funds

 . Lower overall risk of the Portfolio by reducing exposure to both small-cap and
  international stocks and by adding a small cash and a short-term bond position

Sierra Advantage Variable Annuity) that invests in certain funds within The
Sierra Variable Trust. The investment objectives may or may not be met. The
goals of the SAM Program are not intended to reflect past or future performance
of the SAM Program or The Sierra Variable Trust and are in no way a guarantee.

as of 6/30/97.

Goal & Objective

The Growth Portfolio ("Portfolio") is designed to help manage investment risk
and achieve its objective of long-term capital appreciation. The Portfolio
allocates its assets strategically among mutual fund subaccounts in The Sierra
Variable Trust family. The Portfolio is managed similarly to the Sierra Asset
Management (SAM) Program Growth Strategy, whose goal was to produce an average
annual return of 7% or more above the annual rate of inflation over a period of
six years or longer./(1)/

Current Allocation

The Growth Portfolio is well-diversified, its assets allocated among five mutual
funds representing eight major asset classes. By investing in these different
asset classes, the Portfolio works to reduce risk while producing capital
appreciation. The Portfolio's equity holdings are diversified among different
stock asset classes, such as small-, mid-, and large-cap stocks. These
investment subcategories may react differently to certain economic or market
conditions, helping to reduce the risk of market fluctuations. The addition of
bond asset classes, which produce current income for the Portfolio, also helps
to further decrease overall volatility.

More specifically, the Portfolio's current investment strategy is to:

 . Enhance prospects for capital appreciation by maintaining a broadly
  diversified mix of domestic and international stocks favoring the core
  holdings of mid- and large- cap companies

 . Maintain a 75% concentration in equities and 25% in short- to intermediate-
  term fixed-income assets to enhance growth potential while reducing overall
  levels of risk

Goal & Objective

The Balanced Portfolio ("Portfolio") is designed to help manage investment risk
and achieve its objective of long-term growth of capital and income. The
Portfolio allocates its assets strategically among mutual fund subaccounts in
The Sierra Variable Trust family. The Portfolio is managed similarly to The
Sierra Asset Management (SAM) Program Balanced Strategy, whose goal was to
produce an average annual return of 5% or more above the annual rate of
inflation over a period of six years or longer./(1)/

Current Allocation

The Balanced Portfolio is diversified among five mutual funds. Since those funds
represent eight major asset classes of both bonds and stocks, a high degree of
asset diversification is provided to investors. Diversification of stock asset
classes can help to reduce the risk of market fluctuations. Holding diverse bond
asset classes may also work to reduce price volatility due to interest rate
fluctuations. The Portfolio is well positioned as prospects for continued low
inflation will be beneficial for all financial assets.

More specifically, the current investment strategy for the Portfolio is to:

 .     Increase the levels of diversification and manage risk by investing 60% 
      of the Portfolio in equities and 40% in fixed income

 .     Emphasize mid- and large-cap equities while maintaining a foreign position
      and weighting the fixed-income portion towards cash and mortgage-backed
      securities

Goal & Objective

The Value Portfolio ("Portfolio") is designed to help manage investment risk and
achieve its objective of income with some added potential for capital
appreciation. The Portfolio allocates its assets strategically among mutual fund
subaccounts in The Sierra Variable Trust family. The Portfolio is managed
similarly to The Sierra Asset Management (SAM) Program Value Strategy, whose
goal was to produce an average annual return of 4% or more above the annual rate
of inflation over a period of six years or longer./(1)/

Current Allocation

The Value Portfolio is diversified among six mutual funds and one additional
cash position, representing nine major asset classes. This level of
diversification can reduce potential risk, as measured by volatility of returns,
to levels below that of most single-fund holdings. Just as diversification of
stock asset classes reduces the risk of market fluctuations, diversification of
bond asset classes helps to reduce price volatility due to interest rate
fluctuations. Current prospects for low inflation provide a positive backdrop
for both fixed-income and equity markets.

More specifically, the current investment strategy for the Portfolio is to:

 .   Provide investors with income and potential for capital appreciation with an
    80% weight in bonds and a 20% weight in core domestic equities

 .   Maintain a competitive current yield by investing in corporate bonds and
    mortgage-backed securities, which produce higher yields than like-maturity
    Treasuries

Goal & Objective

The Income Portfolio ("Portfolio") is designed to help manage investment risk
and achieve its objective of high levels of income and capital preservation. The
Portfolio allocates its assets strategically among mutual fund subaccounts in
The Sierra Variable Trust family. The Portfolio is managed similarly to the
Sierra Asset Management (SAM) Program Fixed Strategy, whose goal was to produce
an average annual return of 3% or more above the annual rate of inflation over a
period of six years or longer./(1)/

Current Allocation

The Income Portfolio is diversified among five bond funds, including a money
market fund. These funds represent six major asset classes which provide a high
degree of asset diversification for investors. Just as diversification of stock
asset classes reduces the risk of market fluctuations, diversification of bond
asset classes helps to reduce price volatility due to interest rate
fluctuations.

More specifically, the current investment strategy for the Portfolio is to:

 .  Increase the levels of diversification and manage risk by increasing exposure
   to global bonds and adding to the cash position

 .  Maintain a competitive current yield by investing in corporate bonds and
   mortgage-backed securities, which produce higher yields compared to
   similar-maturity Treasuries.

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                           THE SIERRA VARIABLE TRUST
1. ORGANIZATION AND BUSINESS
 
The Sierra Variable Trust (the "Trust") was organized under the laws of the
Commonwealth of Massachusetts on January 29, 1993 as a business entity commonly
known as a "Massachusetts business trust". The Trust is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a no-load,
open-end management investment company. The Trust offers fourteen managed
investment funds, consisting of nine funds: the Global Money Fund (the "Money
Fund"); the Short Term High Quality Bond, Short Term Global Government, U.S.
Government and Corporate Income Funds (the "Bonds Funds"); the Growth and
Income, Growth, Emerging Growth and International Growth Funds (the "Equity
Funds"); (collectively the "Funds" or "Underlying Funds") and five portfolios:
Capital Growth, Growth, Balanced, Value and Income Portfolios (individually a
"Portfolio" and collectively the "Portfolios"), to the public through certain
variable annuity contracts offered by American General Life Insurance Company
("AG Life"). As of June 30, 1997, the Value and Income Portfolios had not
commenced operations. Through investment in the Underlying Funds, the
Portfolios offer a range of asset allocation strategies designed to accommodate
different investment philosophies and goals.
 
The Money Fund invests directly in money market instruments of foreign and U.S.
issuers. The Bond Funds and the Equity Funds invest directly in securities or
other financial instruments. Each Portfolio of the Trust invests, within
predetermined percentage ranges, in up to nine of the Underlying Funds of the
Trust. In order to achieve its investment objective, each Portfolio typically
allocates its assets, within determined percentage ranges, among certain of the
Underlying Funds. The percentages reflect the extent to which each Portfolio
will invest in the particular market segment represented by each Underlying
Fund, and the varying degrees of potential investment risk and reward
represented by each Portfolios' investments in those market segments and their
corresponding Underlying Funds. Sierra Investment Services Corporation ("Sierra
Services") may alter these percentage ranges when it deems appropriate. The
assets of each Portfolio will be allocated among the Underlying Funds in
accordance with its investment objective, Sierra Services' outlook for the
economy and the financial markets and the relative market valuations of the
Underlying Funds. In addition, generally in order to meet liquidity needs or
for temporary defensive purposes, each Portfolio may invest its assets directly
in cash, stock or bond index futures, options, money market securities and
certain short-term debt instruments.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures in the financial statements.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Funds and
Portfolios in the preparation of their financial statements.
 
PORTFOLIO VALUATION:
 
Money Fund: The investments of the Money Fund are valued on the basis of
amortized cost so long as the Trust's Board of Trustees (the "Board of
Trustees") determines that this method constitutes fair value. Amortized cost
involves valuing a portfolio instrument at its cost initially, and, thereafter,
assuming a constant amortization to maturity of any discount or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument. The Money Fund attempts to maintain a constant net asset value
of $1.00 per share.
 
Bond Funds and Equity Funds: A security that is primarily traded on a United
States ("U.S.") or foreign exchange (including securities traded through the
NASDAQ National Market System) is valued at the last sale price on that
exchange or, if there were no sales during the day, at the current quoted bid
price. Portfolio securities that are primarily traded on foreign exchanges are
generally valued at the most recent closing values of such securities on their
respective exchanges. However, when an occurrence subsequent to the time a
value was so established is likely to have changed the value, then the fair
value of those securities will be determined in good faith through
consideration of other factors by or under the direction of the Board of
Trustees or its delegates. Over-the-counter securities that are not traded
through the NASDAQ National Market System and securities listed or traded on
certain foreign exchanges whose operations are similar to the U.S. over-the-
counter market, are valued on the basis of the bid price at the close of
business on each day. Investments in U.S. Government securities (other than
short-term securities) are valued at the average of the quoted bid and asked
prices in the over-the-counter market. The current market value of an option is
the last price on the principal exchange on which such option is traded or, in
the absence of a sale, is the mean between the last bid and offering price. The
value of a futures contract equals the unrealized gain or loss on the contract,
which is determined by marking the contract to the current settlement price for
a like contract acquired on the day on which the futures contract is being
valued. A settlement price may not be issued if the market makes a limited move
with respect to the security or index underlying the futures contract. In such
event, the futures contract will be valued at a fair market value to be
determined by or under the direction of the Board of Trustees. Short-term
investments that mature
 
                                       71
<PAGE>
 
 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
                           THE SIERRA VARIABLE TRUST
in 60 days or less are valued at amortized cost; such investments denominated
in foreign currencies are stated at amortized cost as determined in the foreign
currency, translated to U.S. dollars at the current day's exchange rate.
 
Corporate debt securities and debt securities of U.S. issuers (other than U.S.
Government securities and short-term investments) are valued by an independent
pricing service which utilizes market quotations and transactions, quotations
from dealers and various relationships among securities in determining value.
If not valued by a pricing service, such securities are valued at prices
obtained from independent brokers. Investments with prices that cannot be
readily obtained, if any, are carried at fair value as determined in good faith
under consistently applied procedures established by and under the supervision
of the Board of Trustees.
 
The Capital Growth Portfolio, Growth Portfolio and Balanced Portfolio are
valued at their net asset value per share of each Underlying Fund determined as
of the close of the New York Stock Exchange on the valuation date.
 
REPURCHASE AGREEMENTS:
 
Each Fund or Portfolio may engage in repurchase agreement transactions. Under
the terms of a typical repurchase agreement, the Fund or Portfolio through its
custodian, takes possession of an underlying debt obligation subject to an
obligation of the seller to repurchase, and the Fund or Portfolio to resell,
the obligation at an agreed upon price and time, thereby determining the yield
during the Fund's or Portfolio's holding period. This arrangement results in a
fixed rate of return that is not subject to market fluctuations during the
Fund's or Portfolio's holding period. The value of the collateral is at least
equal at all times to the total amount of the repurchase obligation, including
interest. In the event of counterparty default, the Fund or Portfolio has the
right to use the collateral to offset losses incurred. There is potential loss
to the Fund or Portfolio in the event the Fund or Portfolio is delayed or
prevented from exercising its right to dispose of the collateral securities,
including the risk of a possible decline in the value of the underlying
securities during the period while the Fund or Portfolio seeks to assert its
rights. Each Fund's respective Sub-advisor, acting under the supervision of the
Trust's investment advisor, Sierra Investment Advisors Corporation ("Sierra
Advisors") and the Board of Trustees, reviews the value of the collateral and
the creditworthiness of those banks and dealers with which the Fund enters into
repurchase agreements to evaluate potential risks. Sierra Services, the
Portfolios' investment advisor, acting under the supervision of the Board of
Trustees, reviews the value of the collateral and the creditworthiness of those
banks and dealers with which the Portfolio enters into repurchase agreements to
evaluate potential risks.
 
REVERSE REPURCHASE AGREEMENTS:
 
Except for the Money Fund, all Funds and Portfolios may engage in reverse
repurchase agreements. Reverse repurchase agreements are the same as repurchase
agreements except that, in this instance, the Funds or Portfolios would assume
the role of seller/borrower in the transaction. The Funds or Portfolios may use
reverse repurchase agreements to borrow short term funds. The value of the
reverse repurchase agreements that the Funds or Portfolios have committed to
sell are reflected in the Funds' or Portfolios' Statements of Assets and
Liabilities. The Funds or Portfolios will maintain segregated accounts with the
Trust's custodian consisting of U.S. Government securities, cash or money
market instruments that at all times are in an amount equal to their
obligations under reverse repurchase agreements. Reverse repurchase agreements
involve the risks that the market value of the securities sold by the Funds or
Portfolios may decline below the repurchase price of the securities and, if the
proceeds from the reverse repurchase agreement are invested in securities, that
the market value of the securities bought may decline below the repurchase
price of the securities sold.
 
OPTION CONTRACTS:
 
All Funds, except the Money Fund, may engage in option contracts. The Funds may
use option contracts to manage their exposure to the stock and bond markets and
to fluctuations in interest rates and currency values. The underlying principal
amounts and option values are shown in the Portfolio of Investments under the
captions "Put Options Purchased on Foreign Currency," "Call Options Purchased
on Stock Indices" and "Call Options Written on Foreign Currency". These amounts
reflect each contract's exposure to the underlying instrument at June 30, 1997.
Writing puts and buying calls tends to increase the Funds' exposure to the
underlying instrument. Buying puts and writing calls tends to decrease the
Funds' exposure to the underlying instrument or to hedge other Fund
investments.
 
Upon the purchase of a put option or a call option by the Funds, the premium
paid is recorded as an investment, the value of which is marked-to-market
daily. When a purchased option expires, the Funds will realize a loss in the
amount of the cost of
 
                                       72
<PAGE>
 
 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
                           THE SIERRA VARIABLE TRUST
the option. When the Funds enter into a closing sale transaction, the Funds
will realize a gain or loss depending on whether the sales proceeds from the
closing sale transaction are greater or less than the cost of the option. When
the Funds exercise a put option, they will realize a gain or loss from the sale
of the underlying security and the proceeds from such sale will be decreased by
the premium originally paid. When the Funds exercise a call option, the cost of
the security which the Funds purchase upon exercise will be increased by the
premium originally paid.
 
When the Funds write a call option or a put option, an amount equal to the
premium received by the Funds are recorded as a liability, the value of which
is marked-to-market daily. When a written option expires, the Funds realize a
gain equal to the amount of the premium received. When the Funds enter into a
closing purchase transaction, the Funds realize a gain (or loss if the cost of
the closing purchase transaction exceeds the premium received when the option
was sold) without regard to any unrealized gain or loss on the underlying
security, and the liability related to such option is eliminated. When a
written call option is exercised, the Funds realize a gain or loss from the
sale of the underlying security and the proceeds from such sale are increased
by the premium originally received. When a written put option is exercised, the
amount of the premium originally received will reduce the cost of the security
that the Funds purchased upon exercise.
 
The risk associated with purchasing options is limited to the premium
originally paid. Options written by a Fund involve, to varying degrees, risk of
loss in excess of the option value reflected in the Statements of Assets and
Liabilities. The risk in writing a covered call option is that the Funds may
forego the opportunity of profit if the market price of the underlying security
increases and the option is exercised. The risk in writing a covered put option
is that the Funds may incur a loss if the market price of the underlying
security decreases and the option is exercised. In addition, there is the risk
the Funds may not be able to enter into a closing transaction because of an
illiquid secondary market or, for over-the-counter options, because of a
counterparty's inability to perform.
 
The Short Term High Quality Bond, Short Term Global Government, Growth and
International Growth Funds may engage in options on foreign currency and
options on interest rate futures as a hedge to provide protection against
adverse movements in the value of foreign securities in the portfolio.
 
Certain risks are associated with the use of options on foreign currency and
options on interest rate futures contracts as hedging devices. The predominant
risk is that the movement in the price of the instrument underlying such
options may not correlate perfectly with the movement in the prices of the
assets being hedged. The lack of correlation could render the Funds' hedging
strategy unsuccessful and could result in a loss to the Funds. In addition,
there is the risk that the Funds may not be able to enter into a closing
transaction because of an illiquid secondary market or, for over-the-counter
options, because of the counterparty's inability to perform. Options written by
a Fund involve, to varying degrees, risk of loss in excess of the option value
reflected in the Statements of Assets and Liabilities.
 
FUTURES CONTRACTS:
 
Except for the Money Fund, all Funds and Portfolios may engage in futures
transactions. The Funds and Portfolios may use futures contracts to manage
their exposure to the stock and bond markets and to fluctuations in interest
rates and currency values. The underlying value of a futures contract is
incorporated within the unrealized appreciation/(depreciation) shown in the
Portfolio of Investments under the caption "Futures Contracts". This amount
reflects each contract's exposure to the underlying instrument at June 30,
1997. Buying futures contracts tends to increase the Fund's or Portfolio's
exposure to the underlying instrument. Selling futures contracts tends to
either decrease the Fund's or Portfolio's exposure to the underlying
instrument, or to hedge other Fund or Portfolio investments.
 
Upon entering into a futures contract, the Fund or Portfolio is required to
deposit with the broker an amount of cash or cash equivalents equal to a
certain percentage of the contract amount. This is known as the "initial
margin". Subsequent payments ("variation margin") are made or received by the
Fund or Portfolio each day, depending on the daily fluctuation of the value of
the contract. The daily changes in contract value are recorded as unrealized
gains or losses and the Fund or Portfolio recognizes a realized gain or loss
when the contract is closed. Futures contracts are valued at the settlement
price established by the board of trade or exchange on which they are traded.
 
There are several risks in connection with the use of futures contracts as a
hedging device. Futures contracts involve, to varying degrees, risk of loss in
excess of the futures variation margin reflected in the Statements of Assets
and Liabilities. The change in the value of futures contracts primarily
corresponds with the value of their underlying instruments, which may not
correlate with the change in the value of the hedged instruments. In addition,
there is the risk that the Fund or Portfolio may not be able to enter into a
closing transaction because of an illiquid secondary market.

FOREIGN CURRENCY:
 
The books and records of the Funds and Portfolios are maintained in U.S.
dollars. Foreign currencies, investments and other assets and liabilities are
translated into U.S. dollars at the exchange rates prevailing at the end of the
period, and purchases and sales of investment securities, income and expenses
are translated on the respective dates of such transactions. It is not
practicable to isolate that portion of the results of operations arising as a
result of changes in the foreign exchange rates from the portion that arises
from changes in market prices of investments during the period. Accordingly,
all such changes have been reflected as net gain/(loss) from security
transactions in the Statements of Operations.
 
Unrealized gains and losses, not relating to securities, which result from
changes in foreign currency exchange rates have been included in unrealized
appreciation/(depreciation) of foreign currency and other assets and
liabilities. Unrealized gains and losses of securities, which result from
changes in foreign currency exchange rates as well as changes in market prices
of securities, have been included in unrealized appreciation/(depreciation) of
securities. Net realized foreign currency gains and losses include foreign
currency gains and losses resulting from changes in exchange rates between
trade date and settlement date on investment securities transactions, gains and
losses on foreign currency transactions and the difference between the amounts
of interest and dividends recorded on the books of the Funds and the amount
actually received. The portion of foreign currency gains and losses related to
fluctuation in exchange rates between the initial purchase trade date and
subsequent sale trade date is included in realized gain/(loss) from security
transactions.
 
FORWARD FOREIGN CURRENCY CONTRACTS:
 
The Short Term High Quality Bond, Short Term Global Government, Corporate
Income, Growth and Income, Growth, Emerging Growth and International Growth
Funds may enter into forward foreign currency contracts. Forward foreign
currency contracts are agreements to exchange one currency for another at a
future date and at a specified price. The Funds may use forward foreign
currency contracts to facilitate transactions in foreign securities and to
manage the Funds' foreign currency exposure. The U.S. dollar market value,
contract value and the foreign currencies the Funds have committed to buy or
sell are shown in the Portfolio of Investments under the caption "Schedule of
Forward Foreign Currency Contracts". These amounts represent the aggregate
exposure to each foreign currency the Funds have acquired or hedged through
forward foreign currency contracts at June 30, 1997. Forward foreign currency
contracts are reflected as both a forward foreign currency contract to buy and
a forward foreign currency contract to sell. Forward foreign currency contracts
to buy generally are used to acquire exposure to foreign currencies, while
forward foreign currency contracts to sell are used to hedge the Funds'
investments against currency fluctuations. Also, a forward foreign currency
contract to buy or sell can offset a previously acquired opposite forward
foreign currency contract.
 
Forward foreign currency contracts are marked-to-market daily using foreign
currency exchange rates supplied by an independent pricing service. The change
in a contract's market value is recorded by the Funds as an unrealized gain or
loss. When the contract is closed or delivery is taken, 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.
 
The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the Fund's securities, but it does establish a rate
of exchange that can be achieved in the future. These forward foreign currency
contracts involve market risk in excess of the unrealized
appreciation/(depreciation) of forward foreign currency contracts reflected in
the Funds' Statements of Assets and Liabilities. Although forward foreign
currency contracts used for hedging purposes limit the risk of loss due to a
decline in the value of the hedged currency, they also limit any potential gain
that might result should the value of the currency increase. In addition, the
Funds could be exposed to risks if the counterparties to the contracts are
unable to meet the terms of their contracts. The Fund's Sub-advisor will enter
into forward foreign currency contracts only with parties approved by the Board
of Trustees because there is a risk of loss to the Funds if the counterparties
do not complete the transaction.
 
DOLLAR ROLL TRANSACTIONS:
 
The Short Term High Quality Bond, Short Term Global Government, U.S. Government
and Corporate Income Funds, in order to seek a high level of current income,
may enter into dollar roll transactions with financial institutions to take
advantage of opportunities in the mortgage market. The value of the dollar roll
transactions are reflected in the Funds' Statements of Assets and Liabilities.
A dollar roll transaction involves a sale by the Funds of securities that they
hold with an agreement by the Funds to repurchase similar securities at an
agreed upon price and date. The securities repurchased will bear the same
interest as those sold, but generally will be collateralized at time of
delivery by different pools of mortgages with different prepayment

 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
                           THE SIERRA VARIABLE TRUST

histories than those securities sold. The Funds are paid a fee for entering
into a dollar roll transaction, that is accrued as income over the life of the
dollar roll contract. During the period between the sale and repurchase, the
Funds will not be entitled to receive interest and principal payments on the
securities sold. Management anticipates that the proceeds of the sale will be
invested in additional instruments for the Funds, and the income from these
investments, together with any additional fee income received on the dollar
roll transaction will generate income for the Funds exceeding the interest that
would have been earned on the securities sold. Dollar roll transactions involve
the risk that the market value of the securities sold by the Funds may decline
below the repurchase price of those similar securities which the Fund is
obligated to purchase or that the return earned by the Fund with the proceeds
of a dollar roll may not exceed transaction costs.
 
INDEXED SECURITIES:
 
Each of the Funds, except for the Money Fund, may invest in indexed securities
whose value is linked either directly or inversely to changes in foreign
currencies, interest rates, commodities, inflation, indices, or other reference
instruments. Indexed securities may be more volatile than the reference
instrument itself, but any loss is limited to the amount of the original
investment.
 
ILLIQUID INVESTMENTS:
 
Up to 15% of the assets of each Bond and Equity Fund, and up to 10% of the
assets of the Money Fund, may be invested in securities that are not readily
marketable, including: (1) repurchase agreements with maturities greater than
seven calendar days; (2) time deposits maturing in more than seven calendar
days; (3) except for the Money Fund, to the extent a liquid secondary market
does not exist for the instruments, futures contracts and options thereon; (4)
certain over-the-counter options; (5) for the Money Fund and Growth and Income
Fund certain variable rate demand notes having a demand period of more than
seven days; and (6) securities, the disposition of which are restricted under
Federal securities laws, excluding certain Rule 144A securities as defined
below.
 
Illiquid securities generally cannot be sold or disposed of in the ordinary
course of business within seven days at approximately the value at which the
Funds have valued the investments. This may have an adverse effect on the
Fund's ability to dispose of particular illiquid securities at fair market
value and may limit the Fund's ability to obtain accurate market quotations for
purposes of valuing the securities and calculating the net asset value of
shares of the Fund. The Funds may also purchase securities that are not
registered under the Securities Act of 1933, as amended (the "Act"), but that
can be sold to qualified institutional buyers in accordance with Rule 144A
under the Act ("Rule 144A securities"). Rule 144A securities generally may be
resold only to other qualified institutional buyers. If a particular investment
in Rule 144A securities is not determined to be liquid under guidelines
established by the Board of Trustees, that investment will be included within
the 15% or 10% limitation, as applicable, on investment in illiquid securities.
 
SECURITIES TRANSACTIONS AND INVESTMENT INCOME:
 
Securities transactions are recorded as of the trade date (the date the order
to buy or sell is executed). Realized gains and losses from securities sold are
recorded on the identified cost basis. Interest income is recorded on the
accrual basis and consists of interest accrued and, if applicable, discount
earned less premiums amortized. Dividend income is recorded on the ex-dividend
date, except that certain dividends from foreign securities are recorded as
soon as the Funds are informed of the ex-dividend date.
 
Securities purchased or sold on a when-issued or delayed-delivery basis may be
settled a month or more after the trade date; interest income is not accrued
until settlement date. Each Fund instructs the custodian to segregate assets of
the Fund in a separate account with a current value at least equal to the
amount of its when-issued purchase commitments.
 
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:
 
Dividends from net investment income of the Money Fund are declared daily and
paid monthly. Dividends from net investment income of the Bond Funds and each
of the Balanced, Value and Income Portfolios are declared and paid quarterly.
Dividends from net investment income of the Equity Funds and the Capital Growth
and Growth Portfolios are declared and paid annually. Distributions of any net
long-term capital gains earned by a Fund or Portfolio are made annually.
Distributions of any net short-term capital gains earned by a Fund or Portfolio
are distributed no less frequently than annually at the discretion of the Board
of Trustees. Income distributions and capital gain distributions are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences are primarily due to

differing treatments of income and gains on various investment securities held
by the Funds or Portfolios, timing differences and differing characterization
of distributions made by each Fund or Portfolio as a whole.
 
FEDERAL INCOME TAXES:
 
It is each Fund's and Portfolio's policy to qualify as a regulated investment
company by complying with the requirements of the Internal Revenue Code of
1986, as amended, applicable to regulated investment companies and by, among
other things, distributing substantially all of its taxable and tax-exempt
earnings to its shareholders. Therefore, no Federal income tax provision is
required.
 
EXPENSES:
 
Expenses that are directly related to one of the Funds or Portfolios are
charged directly to that Fund or Portfolio. General expenses of the Trust are
allocated to the Funds or Portfolios based upon the relative net assets of each
Fund or Portfolio. In addition, the Portfolios will indirectly bear their
prorated share of expenses of the Underlying Funds.
 
OTHER:
 
The Corporate Income Fund may purchase floating rate, inverse floating rate and
variable rate obligations. Floating rate obligations have an interest rate that
changes whenever there is a change in the external interest rate, while
variable rate obligations provide for a specified periodic adjustment in the
interest rate. The interest rate on an inverse floating rate obligation (an
"inverse floater") can be expected to move in the opposite direction from the
market rate of interest to which the inverse floater is indexed. The Fund may
purchase floating rate, inverse floating rate and variable rate obligations
that carry a demand feature which would permit the Fund to tender them back to
the issuer or remarketing agent at par value prior to maturity. Frequently,
floating rate, inverse floating rate and variable rate obligations are secured
by letters of credit or other credit support arrangements provided by banks.
The Corporate Income Fund may purchase mortgage-backed securities that are
floating rate, inverse floating rate and variable rate obligations. The Money
Fund and Growth and Income Fund may purchase variable rate demand notes.
Although variable rate demand notes are frequently not rated by credit rating
agencies, unrated notes purchased by the Funds will be of comparable quality at
the time of purchase to rated instruments that may be purchased by such Fund,
as determined by such Fund's Sub-advisor. Moreover, while there may be no
active secondary market with respect to a particular variable rate demand note
purchased by a Fund, the Fund may, upon the notice specified in the note,
demand payment of the principal of and accrued interest on the note at any time
and may resell the note at any time to a third party. The absence of such an
active secondary market, however, could make it difficult for a Fund to dispose
of a particular variable rate demand note in the event the issuer of the note
defaulted on its payment obligations, and the Fund could, for this or other
reasons, suffer a loss to the extent of the default.
 
An inverse floater may be considered to be leveraged to the extent that its
interest rate varies by a magnitude that exceeds the magnitude of the change in
the index rate of interest. The higher degree of leverage inherent in inverse
floaters is associated with greater volatility in their market values.
Accordingly, the duration of an inverse floater may exceed its stated final
maturity. Inherent in these instruments is the risk of potential loss should
the Fund be delayed or prevented from exercising the put feature.

7. ORGANIZATION COSTS
 
Expenses incurred in connection with the organization of the Global Money,
Short Term Global Government, U.S. Government, Corporate Income, Growth and
International Growth Funds and the Portfolios, including the fees and expenses
of registering and qualifying each Fund's and Portfolio's shares for
distribution under Federal and state securities regulations, are being
amortized on a straight-line basis over a period of 60 months from commencement
of operations of each Fund and Portfolio. In the event any of the initial
shares of a Fund or Portfolio are redeemed by any holder thereof during the
amortization period, the proceeds of such redemptions will be reduced by an
amount equal to the pro-rata portion of the applicable Fund's and Portfolio's
unamortized deferred organizational expenses in the same proportion as the
number of shares being redeemed bears to the number of initial shares of such
Fund or Portfolio outstanding at the time of such redemption.

9. GEOGRAPHIC AND INDUSTRY CONCENTRATION
 
All Funds, except the U.S. Government Fund, may invest in securities of foreign
companies and foreign governments. There are certain risks involved in
investing in foreign securities that are in addition to the usual risks
inherent in domestic investments. These risks include those resulting from
future adverse political and economic developments and the possible imposition
of currency exchange blockages or other foreign governmental laws or
restrictions.
 
In addition, the Money Fund may invest at least 25% of its assets in bank
obligations. As a result of this concentration policy, the Fund's investments
may be subject to greater risk than a fund that does not concentrate in the
banking industry. In particular, bank obligations may be subject to the risks
associated with interest rate volatility, changes in Federal and state laws and
regulations governing the banking industry and the inability of borrowers to
pay principal and interest when due. In addition, foreign banks present risks
similar to those investing in foreign securities generally and are not subject
to the same reserve requirements and other regulations as U.S. banks.
 
10. RISK FACTORS OF THE PORTFOLIOS
 
Investing in the Underlying Funds through the Portfolios involves certain
additional expenses and tax results that would not be present in a direct
investment in the Underlying Funds. Under certain circumstances, an Underlying
Fund may determine to make payment of a redemption request by a Portfolio
wholly or partly by a distribution in kind of securities from its portfolio,
instead of cash, in accordance with the rules of the Security and Exchange
Commission. In such cases, the Portfolios may hold securities distributed by an
Underlying Fund until Sierra Services determines that it is appropriate to
dispose of such securities.
 
Certain Underlying Funds may: invest a portion of their assets in foreign
securities; enter into forward foreign currency transactions; lend their
portfolio securities; enter into stock index, interest rate and currency
futures contracts, and options on such contracts; enter into interest rate
swaps or purchase or sell interest rate caps or floors; engage in other types
of options transactions; make short sales; purchase zero coupon and payment-in-
kind bonds; engage in repurchase or reverse repurchase agreements; purchase and
sell "when-issued" securities and engage in "delayed-delivery" transactions;
and engage in various other investment practices each with inherent risks.
 
The Capital Growth Portfolio can invest as much as 50% of its total assets in
the Growth Fund and as much as 50% of its total assets in the Emerging Growth
Fund, each of which Underlying Funds may invest as much as 35% of its total
assets in lower-rated bonds. Securities rated below investment grade generally
involve greater price volatility and risk of principal and income and may be
less liquid than higher rated securities.
 
Certain Portfolios invest as much as 50% of their total assets in the Growth or
Emerging Growth Funds, each of which may invest up to 25% of its total assets
in foreign equity securities and as much as 5% of its total assets in
securities in developing or emerging markets countries. Certain Portfolios
invest as much as 50% of their total assets in the International Growth Fund,
which invests primarily in the foreign equity securities, and may invest as
much as 30% of its total assets in securities in developing or emerging market
countries. These investments will subject such Portfolios to risks associated
with investing in foreign securities including those resulting from future
adverse political and economic developments and the possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions.
 
The officers and Trustees of the Trust also serve as officers and Trustees of
the Underlying Funds. In addition, Sierra Services, the investment advisor and
distributor of each Portfolio, and Sierra Advisors, the investment advisor of
the Underlying Funds, are both wholly-owned subsidiaries of SCMC. Also, Sierra
Services is the distributor of the shares of the Underlying Funds. Conflicts
may arise as these companies seek to fulfill their fiduciary responsibilities
to both the Portfolios and the Underlying Funds.
 
From time to time, one or more of the Underlying Funds used for investment by a
Portfolio may experience relatively large investments or redemptions due to
reallocations or rebalancings by the Portfolios as recommended by Sierra
Services. These transactions will affect the Underlying Funds, since the
Underlying Funds that experience redemptions as a result of the reallocations
or rebalancings may have to sell portfolio securities and Underlying Funds that
receive additional cash will have to invest such cash. While it is impossible
to predict the overall impact of these transactions over time, there could be
adverse effects on portfolio management to the extent that the Underlying Funds
may be required to sell securities or invest cash at times when they would not
otherwise do so. These transactions could also have tax consequences if sales
of securities resulted in gains and could also increase transactions costs.
Sierra Advisors, representing the interests of the Underlying Funds, is

committed to minimizing the impact of Portfolio transactions on the Underlying
Funds; Sierra Services, representing the interest of the shareholders of the
Portfolios, is also committed to minimizing such impact on the Underlying Funds
to the extent it is consistent with pursuing the investment objectives of the
Portfolios. Sierra Advisors and Sierra Services will nevertheless face
conflicts in fulfilling their respective responsibilities because they are
affiliates and employ some of the same investment professionals.
 
11. SUBSEQUENT EVENT
 
Effective July 1, 1997, the merger of GWFC into Washington Mutual was
completed. As a result, Sierra Advisors, Sierra Administration, Sierra Services
and GW Securities are now indirect wholly-owned subsidiaries of Washington
Mutual.
 
On June 27, 1997 Scudder announced that it had entered into an agreement with
The Zurich Group, pursuant to which Scudder would be combined with Zurich
Kemper Investments, Inc. to form Scudder Kemper Investments, Inc. Subject to
various regulatory and other approvals, it is currently anticipated that the
transaction will close in the fourth quarter of 1997.
