ANNUAL REPORT

Dear Investor:

Congratulations on another prosperous year! Strong and sustained economic
growth, rapid technological innovation and low inflation allowed the millennium
to conclude with yet another encore market performance. Yet, 1999 was a
particularly successful year for investors as a variety of market sectors posted
solid gains. While the S&P 500 Index rose an impressive 21.04%, the tech-laden
NASDAQ Composite Index and the small company benchmark Russell 2000 Index both
outperformed the bell-weather indicator, increasing 85.5% and 21.26%
respectively. However, exceptional market results were not limited to the U.S.
The popular International benchmark, the MSCI EAFE Index, (which comprises
markets in Europe, Asia and the Far East) gained 25.27%, spurred by recovery in
a number of emerging economies and strong economic growth in developed markets.

Offering you the best possible investment performance is one of our most honored
and treasured commitments. Our disciplined investment selection process provides
our investors with the broadest and most diversified array of top-flight
investment managers in the industry.

Clearly, our investment process delivers results. Even with the solid
performance of existing advisors, our effort to bring you additional superior
money managers continues vigorously. In 1999, the opportunities for investment
through our partnership with Wells Fargo expanded to include 10 new variable
portfolios, bringing the number of options to 27. We added new funds from Wells
Fargo Variable Trust, American Century and MFS, as well as two new sector funds
from INVESCO, the VIF Health Sciences and the Technology portfolios.

We are committed to driving performance to even higher levels and continuing our
thriving relationship with you. We hope that you continue to make use of this
successful partnership in your future financial planning offerings.

Sincerely,

/s/ Wade Dokken

PERFORMANCE HIGHLIGHTS

     The Fund returned 9.33%(1) for the 12-month period ended December 31, 1999.
The Fund's benchmark is allocated 60% S&P 500 Index(2), which returned 21.04%
during the period, and 40% Lehman Brothers 20+ Bond Index(3), which returned
(2.56)%. The Fund distributed $0.26 per share in dividend income and minimal
capital gains during the period. Please keep in mind past performance is no
guarantee of future results.

     The Fund's portfolio comprises three classes of investments: stocks, bonds
and cash. It normally allocates its assets 60% stocks, 40% bonds and 0% cash. In
early 1999, the Fund had been significantly overweighted in stocks to take
advantage of the rising stock market, but during the first half of the year it
returned to its normal allocation. This shift enabled the Fund to capture
significant gains and take advantage of the stronger performance of the 30-year
bond relative to the S&P 500 Index in the final month of the third quarter. The
Fund ended 1999 with its asset allocation model at 62% stocks, 38% bonds and 0%
cash.

     The Federal Reserve Board (the "Fed") raised interest rates to 5.00% from
4.75% during the second quarter of 1999, citing improved global financial
conditions, recovering foreign economies and continued robustness in the
domestic economy. The S&P 500 Index enjoyed a healthy gain of 7.05% during the
second quarter to end on a new high. June, in particular, was a strong month,
returning 5.55% on the back of May's 2.36% loss. Underpinning the market's
ascent was a consumer confidence level that had not been seen in decades, as the
U.S. economy continued to grow.

     Bond markets, early in the year, experienced disappointing returns as
interest rates remained at their highest levels in over a year and bond prices
fell. Evidence of a troubled second quarter for bonds came in the form of a
continued decline in 30-year U.S. Treasury bond prices, while yields were pushed
up from 4.70% to 6.10% during the eight-month period ended June 30, 1999.
Additionally, yield spreads of corporate bonds widened relative to comparable
maturity U.S. Treasury bonds in June and, as a result, the higher returns of
corporate bonds were negated by the lower performance of equivalent-duration
U.S. Treasury securities.

     In the third and fourth quarters of 1999, the Fed raised interest rates
again, demonstrating that it did not think U.S. inflation had been tamed. In a
reprise of what became one of the recent years' rites of summer, the stock
market sagged in the third quarter as investors grew cautious about the
prospects of extending the nation's economic expansion into its tenth year.
Technology stocks continued to outperform and were largely responsible for the
positive performance of the S&P 500 Index during the fourth quarter. The bond
market staged a rally late in the fourth quarter as nervous investors fled the
lower-performing third quarter stock market.

- ---------------
(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund's managers have voluntarily waived all or a
portion of their management fees or assumed responsibility for other expenses,
which reduces operating expenses and increases total return to shareholders.
Without these reductions the Fund's returns would have been lower. These
reductions may be discontinued at any time. Performance figures of the Fund do
not reflect charges pursuant to the terms of the variable life insurance
policies and variable annuity contracts funded by separate accounts that invest
in the Fund's shares.

Performance shown for the Wells Fargo Variable Trust Asset Allocation Fund for
periods prior to September 20, 1999, reflects performance of the Life and
Annuity Trust Asset Allocation Fund, its predecessor fund. Effective at the
close of business September 17, 1999, the Life and Annuity Trust and Norwest
Select Funds were reorganized into the Wells Fargo Variable Trust Funds.

(2) The S&P 500 Index is an unmanaged index of 500 widely held common stocks
representing, among others, industrial, financial, utility, and transportation
companies listed or traded on national exchanges or over-the-counter markets.
The Fund is a professionally managed mutual fund. You cannot invest directly in
an index.

<PAGE>   7

(3) The Lehman Brothers 20+ Bond Index is an unmanaged index composed of
securities in the U.S. Treasury Index with maturities of 20 years or greater.
The U.S. Treasury Index represents public obligations of the U.S. Treasury with
a remaining maturity of one year or more. You cannot invest directly in an
index.

(4) The Ten Largest Holdings is calculated based on the market value of the
securities divided by total market value of the portfolio.

(5) Represents recommended asset mix. There is no guarantee that the Fund will
continue to hold any one particular security or stay invested in any one sector.
The composition of the Fund's portfolio is subject to change depending on
current market activity.

(6) The chart compares the performance of the Wells Fargo Variable Trust Asset
Allocation Fund since inception with the S&P 500 Index and the Lehman Brothers
20+ Bond Index. The chart assumes a hypothetical $10,000 investment and reflects
all operating expenses. The Fund is a professionally managed mutual fund.

                       VARIABLE TRUST CORPORATE BOND FUND

INCEPTION DATE
9/20/99

PERFORMANCE HIGHLIGHTS

     The Fund returned (0.16%)(1) for the period from September 20, 1999
(commencement of operations) to December 31, 1999. The Fund distributed $0.16
per share in dividend income and no capital gains during the period. Please keep
in mind past performance is no guarantee of future results.

     The Fund had a negative return as long-term interest rates rose. The
duration/average maturity was positioned approximately 10% longer than the
benchmark as the benign inflation environment continued. The Fund's negative
return was due to its long duration in a rising interest rate environment, and
concerns over Y2K which drove high-yield and investment-grade corporate spreads
wider. This rise in rates was driven by strong domestic economic growth with low
inflation.

     In addition, corporate spreads widened on a record level of new-issue
corporate bonds and fears over Y2K disruptions. Portfolio duration hindered
performance, but holdings in energy bonds and real estate investment trusts
(REIT) debentures had a positive impact. The Fund added to its high-yield
exposure as spreads widened in the fourth quarter, and the fundamental earnings
outlook remained very positive for corporations. Consumer spending remained
robust in the fourth quarter and will likely follow through into the first
quarter of the new year.

STRATEGIC OUTLOOK

     While the Fund expects inflation to remain under control, the Federal
Reserve Board may raise interest rates again during the spring and summer of
2000. In such an environment, the Fund's duration will be reduced to neutral and
fundamentals for the corporate sector should remain intact. The Fund will
maintain a full weighting in both high-yield and investment-grade corporate
securities.

- ---------------
(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund managers have voluntarily waived all or a portion
of their management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

(2) The Lehman Brothers Corporate Long Bond Index is a total return index of all
publicly-issued, fixed-rate, non-convertible investment grade domestic corporate
bonds and Yankee Bonds. All bonds have maturities of at least 10 years or more.
The returns are weighted by market value including accrued interest. The bonds
represented in this index are subject to investment risk, including loss of
principal, if sold prior to maturity, and also to default. You cannot invest
directly in an index.

(3) The average credit rating is compiled from the ratings of Standards & Poor's
and/or Moody's Investors Service (together "rating agencies"). Standard & Poor's
is a trademark of McGraw-Hill, Inc., and has been licensed. The Fund is not
sponsored, sold or promoted by these rating agencies and these rating agencies
make no representation regarding the advisability of investing in the Fund.

(4) The distribution rate is based on the actual distributions made by the Fund.
The distribution rate is calculated by annualizing the Fund's most recent income
dividend and dividing that figure by the applicable current public offering
price.

(5) The formula used to calculate the SEC yield is described in detail in the
Fund's Statement of Additional Information and is designed to standardize the
yield calculations so that all mutual fund companies with the same or similar
portfolios quote a uniform yield figure for their non-money market
advertisements. SEC yields include the actual amount of interest earned adjusted
by any gain or loss realized due to the return of principal, less expenses and
the maximum offering price calculated on a 30-day month-end basis.

(6) Portfolio holdings are subject to change.

(7) The chart compares the performance of the Wells Fargo Variable Trust
Corporate Bond Fund since inception with the Lehman Brothers Corporate Long Bond
Index. The chart assumes a hypothetical $10,000 investment and reflects all
operating expenses. The fund is a professionally managed mutual fund.

                       VARIABLE TRUST EQUITY INCOME FUND

INVESTMENT OBJECTIVE

The Wells Fargo Variable Trust Equity Income Fund (the "Fund") seeks long-term
capital appreciation and above-average dividend income.

PERFORMANCE HIGHLIGHTS

     The Fund returned 7.90%(1) for the 12-month period ended December 31, 1999,
underperforming the S&P 500 Index(2), which returned 21.04% for the period, but
outperforming the Russell 1000 Value Index(3), which returned 7.35%. The Fund
underperformed the S&P 500 Index as it chose to underweight in the technology
sector. Valuations for technology stocks were at historically high levels,
especially for large cap technology stocks. Excluding the technology and
telecommunications companies in the S&P 500 Index, the remaining 434 companies
actually declined by 4.2% for 1999. The Fund distributed $0.17 per share in
dividend income and no capital gains during the period. Please keep in mind past
performance is no guarantee of future results.

     The Fund benefited from its overweighted position in capital goods stocks,
such as General Electric and Honeywell; energy stocks including Atlantic
Richfield, Royal Dutch and Schlumberger; and financial holdings, including
American Express and J.P. Morgan. In the financial sector, the Fund built a
position in St. Paul Companies, the fourth largest property/casualty company in
the country. St. Paul Companies, which trades at about book value, grew its
dividend 7% annually over the past five years and sells at less than 12 times
earnings. The Fund rebounded 65% from the depressed levels of 1998.

     U.S. Bancorp, which was down 35% in 1999, announced it would not meet
fourth quarter earnings estimates. Tyco International was down based on
questions concerning liberal accounting practices that may have resulted in
higher earnings being reported than if more conservative accounting methods had
been utilized. The stock price was even for the year after dropping 30% in value
in the fourth quarter.

     The Fund added IBM and Disney during the fourth quarter. IBM's earnings
were expected to grow about 18% and double-digit revenue and earnings per share
growth were expected over the next three years. The Fund believes that Disney is
a tremendous franchise and provides significant growth opportunities in its film
and broadcasting divisions, theme parks and resorts.

     Over the past year, the Fund has seen very good value in the consumer goods
sector and has been building its positions in Fortune Brands, Pepsico and May
Department Stores. These all have had double digit annual earnings growth over
the past five years that has not been recognized in their stock prices.

STRATEGIC OUTLOOK

     The Fund expects slower economic growth in the U.S. in 2000, but increased
growth in Europe and Asia. As foreign economies improve, the Fund should benefit
from its exposure to many U.S. companies that derive 35% to 50% of their revenue
from non-U.S. sources. If, however, growth in technology continues to
accelerate, Fund performance could lag as a result of its lower weighting in the
technology sector.

- ---------------
(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund managers have voluntarily waived all or a portion
of their management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

Performance shown for the Wells Fargo Variable Trust Equity Income Fund for
periods prior to September 20, 1999, reflects performance of the Norwest Select
Income Equity Fund, its predecessor fund. Effective at the close of business
September 17, 1999, the Life and Annuity Trust and Norwest Select Funds were
reorganized into the Wells Fargo Variable Trust Funds.

(2) The S&P 500 Index is an unmanaged index of 500 widely held common stocks
representing, among others, industrial, financial, utility, and transportation
companies listed or traded on national exchanges or over-the-counter markets.
The Fund is a professionally managed mutual fund. You cannot invest directly in
an index.

(3) The Russell 1000 Value Index measures the performance of those Russell 1000
companies with lower price-to-book ratios and lower forecasted growth values.
You cannot invest directly in an index.

(4) The formula used to calculate the SEC yield is described in detail in the
Fund's Statement of Additional Information and is designed to standardize the
yield calculations so that all mutual fund companies with the same or similar
portfolios quote a uniform yield figure for their non-money market
advertisements. SEC yields include the actual amount of interest earned adjusted
by any gain or loss realized due to the return of principal, less expenses and
the maximum offering price calculated on a 30-day month-end basis.

(5) The Ten Largest Equity Holdings is calculated based on the market value of
the securities divided by total market value of the portfolio.

(5) The Ten Largest Equity Holdings is calculated based on the market value of
the securities divided by total market value of the portfolio.

(6) Portfolio holdings are subject to change.

(7) The chart compares the performance of the Wells Fargo Variable Trust Equity
Income Fund since inception with the S&P 500 Index and the Russell 1000 Value
Index. The chart assumes a hypothetical $10,000 investment and reflects all
operating expenses. The Fund is a professionally managed mutual fund.

                        VARIABLE TRUST EQUITY VALUE FUND

INVESTMENT OBJECTIVE

The Wells Fargo Variable Trust Equity Value Fund (the "Fund") seeks long-term
capital appreciation. The Fund invests in common stocks and foreign and domestic
convertible debt securities.

PERFORMANCE HIGHLIGHTS

     The Fund returned (2.48)%(1) for the 12-month period ended December 31,
1999. The Fund underperformed the S&P 500 Index(2), which returned 21.04%, and
the Russell 1000 Value Index(3), which returned 7.35%. The Fund underperformed
due to overall weakness in the returns provided by traditional value strategies,
market capitalization less than that of the benchmark in the first half of the
year and an emphasis on deeply discounted stocks. Another way to view the Fund's
performance is that it was contained within a rather narrow group of stocks that
failed to meet the disciplined value parameters of the Fund. The Fund
distributed $0.08 per share in dividend income and no capital gains during the
period. Please keep in mind past performance is no guarantee of future results.

     Economic factors changed significantly over the 12-month period. In the
first quarter, investors were still cautious following the Asian economic
crisis. This emphasis on safety allowed only large and liquid stocks to
outperform. In the second quarter, Asian worries abated and the Fund benefited
from broad market improvement and the effect of higher oil prices on energy
stocks. The third quarter was the Fund's worst period as Y2K worries peaked and
interest rates moved higher. During the fourth quarter, improving global and
domestic economic conditions began to positively influence certain cyclical and
industrial stocks.

     Stocks that provided the best performance during the year included Alcoa
(basic goods), Exxon Mobil (energy), Honeywell (producer durables), Apple
Computer, IBM and Motorola (technology), and Morgan Stanley Dean Witter and
Citigroup (brokerage/financial).

STRATEGIC OUTLOOK

     The Fund expects continued improvement in global economic conditions,
healthy domestic economic conditions and higher interest rates in the coming
year. A higher interest rate scenario implies a higher level of economic growth,
which would be helpful for basic goods and industrial companies. Technology may
continue to present excellent growth opportunities, and the Fund is expected to
participate to the extent that it can under its value discipline.

     Value versus growth was the subject of considerable debate at the end of
the period. Growth stocks have dominated over the past few years due to factors
such as technological innovation and other disinflationary factors. Growth
stocks were trading at extremely high levels of valuation and inflation is
currently creeping higher. Under these conditions, traditional value investment
strategies may start to provide better relative and nominal returns.

(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund managers have voluntarily waived all or a portion
of their management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

Performance shown for the Wells Fargo Variable Trust Equity Value Fund for
periods prior to September 20, 1999, reflects performance of the Life and
Annuity Trust Equity Value Fund, its predecessor fund. Effective at the close of
business September 17, 1999, the Life and Annuity Trust and Norwest Select Funds
were reorganized into the Wells Fargo Variable Trust Funds.

(2) The S&P 500 Index is an unmanaged index of 500 widely held common stocks
representing, among others, industrial, financial, utility, and transportation
companies listed or traded on national exchanges or over-the-counter markets.
The Fund is a professionally managed mutual fund. You cannot invest directly in
an index.

(3) The Russell 1000 Value Index measures the performance of those Russell 1000
companies with lower price-to-book ratios and lower forecasted growth values.
You cannot invest directly in an index.

(4) The Ten Largest Equity Holdings is calculated based on the securities market
value divided by total market value of the portfolio.

(5) Portfolio holdings are subject to change.

(6) The chart compares the performance of the Wells Fargo Variable Trust Equity
Value Fund since inception with the S&P 500 and the Russell 1000 Value Index.
The chart assumes a hypothetical $10,000 investment and reflects all operating
expenses. The Fund is a professionally managed mutual fund.

                           VARIABLE TRUST GROWTH FUND

INVESTMENT OBJECTIVE

The Wells Fargo Variable Trust Growth Fund (the "Fund") seeks long-term capital
appreciation by investing primarily in common stocks, preferred stocks and
convertible debt securities.

ADVISOR
Wells Fargo Bank, N.A.

FUND MANAGER
Kelli Hill

INCEPTION DATE
4/12/94

PERFORMANCE HIGHLIGHTS

     The Fund returned 20.41%(1) for the 12-month period ended December 31,
1999. The Fund slightly underperformed its benchmark, the S&P 500 Index(2) which
returned 21.04%. The Fund distributed $0.03 per share in dividend income and no
capital gains during the period. Please keep in mind past performance is no
guarantee of future results.

     The Fund finished 1999 slightly below the benchmark in what could have been
considered an extremely volatile environment. While rotation from growth stocks
to value stocks helped fuel much of this volatility, the technology sector was
clearly a contributor to performance throughout much of the year. Earnings were
strong for the first three quarters across the board, however the disparity
across sector performance remained great over the course of the year. Even
technology managed to stage a comeback at the end of the third quarter with a
positive return. The financial sector had a mixed personality in 1999, with very
strong performance in the first half and then giving most of the gain back in
the third quarter with no recovery in the fourth quarter. In both sectors, stock
selection was a key element to outperformance.

     The year began with the fear of rising interest rates, but by March that
fear had subsided. As the second quarter unfolded, the world economy showed
signs of recovery with money flowing from large, consistent growth stocks into
cyclical and value stocks as the S&P 500 earnings growth began to accelerate.
However, the third quarter was an example of a reversal of fortune for value
stocks as the market narrowed and momentum prevailed.

     The biggest contributors to performance were in the technology sector. JDS
Uniphase was up 287.83%, while Veritas Software was up 270.75%. The Fund added
to these positions as well as to Nortel, Cisco Systems and Microsoft in an
effort to overweight the technology sector in the fourth quarter.

STRATEGIC OUTLOOK

     The outlook for financial markets for the first half of 2000 could be more
subdued than the last half of 1999, with the uncertainty of higher interest
rates becoming a reality. The Fund believes visibility will be key to its
strategy in 2000, and it anticipates that companies able to demonstrate solid,
visible earnings growth going forward will command a premium in the overall
market. The Fund will continue to look for earnings growth and relative
price/earnings growth, which will be even more important this year.

(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund's manager has voluntarily waived all or a portion
of its management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

Performance shown for the Wells Fargo Variable Trust Growth Fund for periods
prior to September 20, 1999, reflects performance of the Life and Annuity Trust
Growth Fund, its predecessor fund. Effective at the close of business September
17, 1999, the Life and Annuity Trust and Norwest Select Funds were reorganized
into the Wells Fargo Variable Trust Funds.

(2) The S&P 500 Index is an unmanaged index of 500 widely held common stocks
representing, among others, industrial, financial, utility and transportation
companies listed or traded on national exchanges or over-the-counter markets.
The Fund is a professionally managed mutual fund. You cannot invest directly in
an index.

(3) The Ten Largest Equity Holdings is calculated based on the securities market
value divided by total market value of the portfolio.

(4) Portfolio holdings are subject to change.

(5) The chart compares the performance of the Wells Fargo Variable Trust Growth
Fund since inception with the S&P 500 Index. The chart assumes a hypothetical
$10,000 investment and reflects all operating expenses. The Fund is a
professionally managed mutual fund.

                    VARIABLE TRUST LARGE COMPANY GROWTH FUND

INVESTMENT OBJECTIVE

The Wells Fargo Variable Trust Large Company Growth Fund (the "Fund") seeks
long-term capital appreciation by investing primarily in large, high-quality
domestic companies.

ADVISOR
Wells Fargo Bank, N.A.

FUND MANAGERS
John S. Dale, CFA
Gary E. Nussbaum, CFA

INCEPTION DATE
9/20/99

PERFORMANCE HIGHLIGHTS

     The Fund returned 20.30%(1) for the period from September 20, 1999
(commencement of operations) to December 31, 1999, slightly outperforming its
benchmark, the S&P 500 Index(2) which returned 14.88% for the three-month period
ended December 31, 1999. The Fund distributed no dividend income or capital
gains during the period. Please keep in mind past performance is no guarantee of
future results.

     A disproportionate level of the Fund's return came from the largest
holdings in the Fund, such as Cisco Systems, Microsoft, Home Depot and American
International. Other strong performers included First Data Corporation, Ericsson
and Charles Schwab. The Fund had no portfolio turnover during the period because
all holdings met or exceeded the Fund's long-term fundamental expectations.

STRATEGIC OUTLOOK

     Although corrections are inevitable and necessary, the stock market is
standing on generally solid ground. Strong corporate profit growth is providing
a firm underpinning to the stock market. Improving global economies are reducing
the world's dependence on the U.S. economy. And, very importantly, outstanding
U.S. productivity gains are offsetting higher wages and commodity prices,
resulting in continued low inflation. As in the past, future stock market
drivers will be corporate earnings growth and price/earnings ratios. The Fund's
strong positioning in current market conditions gives it confidence and optimism
for the future.

(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund managers have voluntarily waived all or a portion
of their management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

(2) The S&P 500 Index is an unmanaged index of 500 widely held common stocks
representing, among others, industrial, financial, utility and transportation
companies listed or traded on national exchanges or over-the-counter markets.
The Fund is a professionally managed mutual fund. You cannot invest directly in
an index.

(3) The Ten Largest Equity Holdings is calculated based on the market value of
the securities divided by total market value of the portfolio.

(4) Portfolio holdings are subject to change.

(5) The chart compares the performance of the Wells Fargo Variable Trust Large
Company Growth Fund since inception with the S&P 500 Index. The chart assumes a
hypothetical $10,000 investment and reflects all operating expenses. The Fund is
a professionally managed mutual fund.

                        VARIABLE TRUST MONEY MARKET FUND

INVESTMENT OBJECTIVE

The Wells Fargo Variable Trust Money Market Fund (the "Fund") seeks high current
income, while preserving capital and liquidity, by investing in high-quality,
short-term instruments.

ADVISOR
Wells Fargo Bank, N.A.

FUND MANAGERS
Dave Sylvester
Laurie White
Mike Neitzke

INCEPTION DATE
5/19/94

PERFORMANCE HIGHLIGHTS

     The Fund returned 4.46%(1) for the 12-month period ended December 31, 1999,
and the 30-day simple yield was 5.04%. The Fund distributed $0.04 per share in
dividend income and no capital gains during the period. Please keep in mind past
performance is no guarantee of future results.

     During most of the period, the Fund maintained a longer than average
weighted maturity to take advantage of a steepening yield curve. The Federal
Reserve Board raised interest rates three times in 1999, most recently on
November 16, 1999, to 5.50%. Toward the end of the year, the Fund added
securities maturing in January and February, taking advantage of attractive
yields caused by issuers' needs for funding over year-end. It also targeted
maturity dates for fixed-rate securities to ensure adequate liquidity in the
one-month period surrounding year-end.

     The average maturity of the Fund at each quarter-end was 60 days for the
first quarter, 65 days for the second quarter, 75 days for the third quarter and
57 days at year-end. The Fund increased liquidity at the end of the year to
accommodate the need for funding at year-end. Cash flows did not affect
management of the portfolio throughout the year.

STRATEGIC OUTLOOK

     Economic growth may be on the verge of slowing but possibly not fast enough
to forestall further interest rate increases during 2000. However, there are
several reasons why future interest rate increases are likely to be modest.
First, inflation is expected to be little changed from the 2%-2.5% rate in 1999.
Second, real or inflation-adjusted interest rates already are at historic highs,
suggesting that only modest, additional increases in those rates may be
necessary to sufficiently slow the economy.

(1) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return will fluctuate. The Fund's yield figures more closely
reflect the current earnings of the Fund than the total return figures. The Fund
managers have voluntarily waived all or a portion of their management fees or
assumed responsibility for other expenses, which reduces operating expenses and
increases total return to shareholders. Without these reductions the Fund's
returns would have been lower. These reductions may be discontinued at any time.
Performance figures of the Fund do not reflect charges pursuant to the terms of
the variable life insurance policies and variable annuity contracts funded by
separate accounts that invest in the Fund's shares.

Performance shown for the Wells Fargo Variable Trust Money Market Fund for
periods prior to September 20, 1999, reflects performance of the Life and
Annuity Trust Money Market Fund, its predecessor fund. Effective at the close of
business September 17, 1999, the Life and Annuity Trust and Norwest Select Funds
were reorganized into the Wells Fargo Variable Trust Funds.

PERFORMANCE HIGHLIGHTS

     The Fund returned 66.27%(2) for the 12-month period ended December 31,
1999, outperforming the Russell 2000 Index, which returned 21.26%. The Fund
distributed no dividends or capital gains during the period. Please keep in mind
past performance is no guarantee of future results.

     Small cap stocks began to rebound in the second half of 1999 following a
long bear market relative to large cap stocks. During the second half of 1999,
the Fund experienced accelerating outperformance attributed to stock selection
concentrated in the technology sector and continuous analysis of portfolio
exposure. The Fund's portfolio analysis led it to participate in the hot
subsectors within the small cap universe, including semiconductor,
telecommunications services and e-commerce infrastructure, while limiting
exposure to poor performing groups, such as client-server software, health care
services and consumer staples.

     Individual holdings that outperformed in 1999 included Broadvision and
Vignette (internet infrastructure), True North and Cumulus (advertising/radio),
Pharmacyclics and IDEC Pharma (biotechnology) and Optical Coating Labs (fiber
optics).

STRATEGIC OUTLOOK

     The Fund will continue to search for companies that can grow earnings
independent of the economic cycle. The Fund expects small cap stocks to grow in
2000, and it believes that a new, longer-term small cap growth cycle has begun.

(1) The Russell 2000 Index is an index subset of the Russell 3000 Index and
includes the 2,000 smallest stocks representing approximately 11% of the U.S.
equity market. You cannot invest directly in an index.

(2) FIGURES QUOTED REPRESENT PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE
RESULTS. Investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Fund managers have voluntarily waived all or a portion
of their management fees or assumed responsibility for other expenses, which
reduces operating expenses and increases total return to shareholders. Without
these reductions the Fund's returns would have been lower. These reductions may
be discontinued at any time. Performance figures of the Fund do not reflect
charges pursuant to the terms of the variable life insurance policies and
variable annuity contracts funded by separate accounts that invest in the Fund's
shares.

Performance shown for the Wells Fargo Variable Trust Small Cap Growth Fund for
periods prior to September 20, 1999, reflects performance of the Norwest Select
Small Company Stock Fund (the accounting survivor of a merger of the Life and
Annuity Trust Strategic Growth Fund and the Norwest Select Small Company Stock
Fund), its predecessor fund. Effective at the close of business September 17,
1999, the Life and Annuity Trust and Norwest Select Funds were reorganized into
the Wells Fargo Variable Trust Funds.

(3) The Ten Largest Equity Holdings is calculated based on the market value of
the securities divided by total market value of the portfolio.

(4) Portfolio holdings are subject to change.

(5) The chart compares the performance of the Wells Fargo Variable Trust Small
Cap Growth Fund since inception with the Russell 2000 Index. The chart assumes a
hypothetical $10,000 investment and reflects all operating expenses. The Fund is
a professionally managed mutual fund.

    The ratio of Gross Expenses to Average Net Assets reflects the expense ratio
    in the absence of any waivers and reimbursements (Note 9).

(2) Total return calculations do not include any sales charges, and would have
    been lower had certain expenses not been waived or reimbursed during the
    period shown. Total return figures do not reflect charges pursuant to the
    terms of the variable life insurance policies and variable annuity contracts

NOTES TO FINANCIAL STATEMENTS

1.   ORGANIZATION

Wells Fargo Variable Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end series
management investment company. The Trust currently consists of eight separate
diversified funds (each, a "Fund", collectively, the "Funds"): the Asset
Allocation, Corporate Bond, Equity Income, Equity Value, Growth, Large Company
Growth, Money Market, and Small Cap Growth Funds. The Funds are available
exclusively as pooled funding vehicles for certain participating life insurance
companies offering variable annuity contracts and variable life insurance
policies.

Concurrent with the establishment of the Trust, the Board of Trustees of the
Life & Annuity Trust ("LAT") and the Board of Trustees of the Norwest Select
Funds ("Select") approved a consolidation agreement providing for the
acquisition of the assets and the assumption of liabilities of certain LAT and
Norwest Select Funds into the Wells Fargo Variable Trust Funds. Effective on the
close of business September 17, 1999 the LAT and/or Select Funds were
consolidated into the respective Wells Fargo Variable Trust Funds through an
exchange of shares as follows:

 ** Select Fund accounting survivor
*** New Fund. No accounting survivor

Concurrent with the reorganization of the LAT Strategic Growth Fund and the
Norwest Select Small Company Stock Fund into the Wells Fargo Variable Trust
Small Cap Growth Fund, the Wells Fargo Variable Trust Small Cap Growth Fund
acquired all the net assets of the LAT Strategic Growth Fund and Norwest Select
Small Company Stock Fund. The LAT Strategic Growth Fund exchanged its 173,629
shares (valued at $2,616,673 million, including $270,587 of unrealized
appreciation) for 239,403 shares of the Wells Fargo Variable Trust Small Cap
Growth Fund. The Select Small Company Stock Fund, as accounting survivor,
exchanged its shares at a rate of one for one carrying all of its assets and
liabilities (valued at $12,170,942) into the Wells Fargo Variable Trust Small
Cap Growth Fund.

The Wells Fargo Variable Trust Corporate Bond and Large Company Growth Funds did
receive assets from the LAT and Select Trust Funds, but have a different
investment objective, among other operating differences, than those respective
LAT and Select Trust Funds. Thus, the Wells Fargo Variable Trust Corporate Bond
and Large Company Growth Funds do not have an accounting survivor and commenced
operations on September 20, 1999 for financial reporting purposes.

2.   SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies which are consistently followed by
the Trust in the preparation of its financial statements are in conformity with
generally accepted accounting principles ("GAAP") for investment companies.

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities, disclosure of contingent assets and liabilities at the
date of the

                                       82
<PAGE>   83
NOTES TO FINANCIAL STATEMENTS

financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

SECURITY VALUATION

Investments in securities for all Funds, with the exception of the Money Market
Fund, are valued at the close of each business day. Securities which are traded
on a national or foreign securities exchange or the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market are valued at
the last reported sales price. In the absence of any sale of such securities,
and in the case of other securities, including U.S. Government obligations, but
excluding debt securities maturing in 60 days or less, the valuations are based
on the latest quoted bid prices. Securities denominated in foreign currencies
are translated into U.S. dollars using the closing rates of exchange in effect
on the day of valuation. Securities for which quotations are not readily
available are valued at fair value as determined by policies set by the Trust's
Board of Trustees.

The Money Market Fund invests only in securities with remaining maturities not
exceeding 397 days (13 months). Securities held in the Money Market Fund and
debt securities maturing in 60 days or less are valued using the amortized cost
method which involves valuing a security at its cost, plus accretion of discount
or minus amortization of premium over the period until maturity, which
approximates market value. The Money Market Fund seeks to maintain a constant
net asset value of $1.00 per share, although there is no assurance that it will
be able to do so.

SECURITY TRANSACTIONS AND INCOME RECOGNITION

Securities transactions are recorded on a trade date basis. Realized gains or
losses are reported on the basis of identified cost of securities delivered.
Interest income is accrued daily and bond discounts are accreted and premiums
are amortized under provisions of the Internal Revenue Code of 1986, as amended
(the "Code").

Dividend income is recognized on the ex-dividend date [except for certain
dividends from foreign securities, which are recorded as soon as the Fund is
informed of the ex-dividend date]. Dividend income from foreign securities is
recorded net of foreign taxes withheld where recovery of such taxes is not
assured.

Foreign currency amounts are translated into U.S. dollars at the mean of the bid
and ask price of such currencies against U.S. dollars as follows: (i) assets and
liabilities at the rate of exchange at the end of the respective period; and
(ii) purchases and sales of securities and income and expenses at the rate of
exchange prevailing on the dates of such transactions. The portion of the
results of operations arising from changes in the exchange rates and the portion
due to fluctuations arising from changes in the market prices of securities are
not isolated. Such fluctuations are included with the net realized and
unrealized gain or loss on investments.

REPURCHASE AGREEMENTS

Each Fund may invest in repurchase agreements and may participate in pooled
repurchase agreement transactions with other funds advised by Wells Fargo Bank,
N.A. ("WFB"). The repurchase agreements must be fully collateralized based on
values that are marked to market daily. The collateral may be held by an agent
bank under a tri-party agreement. It is the Funds' custodians' responsibility to
value collateral daily and to take action to obtain additional collateral as
necessary to maintain market value equal to or greater than the resale price.
The repurchase agreements held by the Funds are collateralized by instruments
such as U.S. Treasury or federal agency obligations.

FUTURES CONTRACTS

The Asset Allocation and Equity Value Funds may purchase futures contracts to
gain exposure to market changes, which may be more efficient or cost effective
than actually buying the securities. A futures contract is an agreement between
parties to buy or sell a security at a set price on a future date. Upon entering
into such a contract, a Fund is required to pledge to the broker an amount of
cash, U.S. Government obligations or other high-quality debt securities equal to
the minimum "initial

                                       83
<PAGE>   84
NOTES TO FINANCIAL STATEMENTS

margin" requirements of the exchange on which the futures contract is traded.
Pursuant to the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in the value of the contract.
Such receipts or payments are known as "variation margin" and are recorded by
the Fund as unrealized gains or losses. When the contract is closed, the Fund
records 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.
Pursuant to regulations and/or published positions of the Securities and
Exchange Commission (the "SEC") for long futures positions, the Fund is required
to segregate highly liquid securities as permitted by the SEC in connection with
futures transactions in an amount generally equal to the entire value of the
underlying contracts.

Risks of entering into futures contracts include the possibility that there may
be an illiquid market and that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. On December
31, 1999, the Asset Allocation Fund held the following long futures contracts:

The Asset Allocation Fund has pledged to brokers U.S. Treasury bills for initial
margin requirements with a par value of $250,000.

Forward Foreign Currency Contract

At December 31, 1999, the Corporate Bond Fund had entered into a forward foreign
currency contract under which it is obligated to exchange currencies at a
specified future date. The Fund had an outstanding contract to sell EURO$538,000
and receive $545,155 on February 9, 2000. Net unrealized appreciation of $4,573
on this contract is included in the accompanying financial statements. Risks
arise from the possible inability of counterparties to meet the terms of their
contracts and from movements in currency values.

Reclassification of Capital Accounts

On the statement of assets and liabilities, as a result of permanent book-to-tax
and merger-related differences, reclassification adjustments were made as

Distributions to Shareholders

Dividends to shareholders from net investment income, if any, for the Growth,
Large Company Growth, and Small Cap Growth Funds are declared and distributed
annually. Dividends to shareholders from net investment income, if any, for the
Asset Allocation, Equity Income, and Equity Value Funds are declared and
distributed quarterly. Dividends to shareholders from net investment income, if
any, for the Corporate Bond and Money Market Funds are declared daily and
distributed monthly. Distributions to shareholders from net realized capital

                                       84
<PAGE>   85
NOTES TO FINANCIAL STATEMENTS

Distributions are based on amounts calculated in accordance with the applicable
federal income tax regulations, which may differ from generally accepted
accounting principles. The timing and character of distributions made during the
period from net investment income or net realized gains may also differ from
their ultimate characterization for federal income tax purposes. The differences
between the income or gains distributed on a book versus tax basis are shown as
excess distributions of net investment income and net realized gain on sales of
investments in the accompanying Statements of Changes in Net Assets. To the
extent that these differences are permanent in nature, such amounts are
reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassifications.

Federal Income Taxes

Each Fund of the Trust is treated as a separate entity for federal income tax
purposes. It is the policy of each Fund to continue to qualify as a regulated
investment company by complying with the provisions applicable to regulated
investment companies, as defined in the Code, and to make distributions of
substantially all of its investment company taxable income and any net realized
capital gains (after reduction for capital loss carryforwards) sufficient to
relieve it from all, or substantially all, federal income taxes. Accordingly, no
provision for federal income taxes was required at December 31, 1999.

For tax purposes, the Corporate Bond, Equity Value, and Large Company Growth
Funds have current year deferred post-October capital losses of $35,028, $52,061
and $83,423, respectively. These losses will be realized for tax purposes on the
first day of the succeeding year. The following Funds had estimated net capital
loss carryforwards at December 31, 1999, which are available to offset future
net realized capital gains:

                          INDEPENDENT AUDITORS' REPORT

THE BOARD OF TRUSTEES AND
SHAREHOLDERS OF WELLS FARGO VARIABLE TRUST FUNDS:

     We have audited the accompanying statements of assets and liabilities of
Asset Allocation Fund, Corporate Bond Fund, Equity Income Fund, Equity Value
Fund, Growth Fund, Large Company Growth Fund, Money Market Fund and Small Cap
Growth Fund, portfolios of Wells Fargo Variable Trust Funds, including the
schedules of investments, as of December 31, 1999, and the related statements of
operations for the year then ended for Asset Allocation Fund, Equity Income
Fund, Equity Value Fund, Growth Fund, Money Market Fund and Small Cap Growth
Fund, and for the period from September 20, 1999 (commencement of operations) to
December 31, 1999 for Corporate Bond Fund and Large Company Growth Fund, the
statements of changes in net assets for each of the years in the two-year period
then ended for Asset Allocation Fund, Equity Income Fund, Growth Fund, Money
Market Fund and Small Cap Growth Fund, the year ended December 31, 1999 and the
period from May 1, 1998 (commencement of operations) to December 31, 1998 for
the Equity Value Fund and the period from September 20, 1999 (commencement of
operations) to December 31, 1999 for Corporate Bond Fund and Large Company
Growth Fund and financial highlights for each of the years or periods indicated
herein. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1999 by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Asset Allocation Fund, Corporate Bond Fund, Equity Income Fund, Equity Value
Fund, Growth Fund, Large Company Growth Fund, Money Market Fund and Small Cap
Growth Fund as of December 31, 1999, the results of their operations, changes in
their net assets and their financial highlights for the years or periods
presented above in conformity with generally accepted accounting principles.
