GENERAL DISCUSSION
By Portfolio Manager Pam Bledsoe

MARKET CONDITIONS
As expected by the marketplace, the Federal Reserve (Fed) increased the Federal
Funds rate by .25% on June 30, 1999, citing the need to be pre-emptive against
any inflationary pressures that could result from the domestic economy growing
too quickly. Over the course of the last few months, numerous economic
statistics have been released indicating the strength of the U.S. economy. As
represented by statistics such as job growth, wages, and manufacturing strength,
the U.S. economy appears to be going full steam ahead. This rate increase sought
to balance actions implemented by the Fed during October and November of 1998,
which lowered the Federal Funds rate by .75%. At that time, the Fed sought to
offset a slowdown in the U.S. economy that could have been caused by reduced
trade with other countries.

PORTFOLIO STRATEGY
Strong indicators of the robust growth in the U.S. economy have caused market
interest rates to rise over the past few weeks. One-third of the portfolio is in
variable rate demand notes and this portion of the portfolio resets at the
higher rate on a weekly basis. The balance of the portfolio was comprised of
short-term commercial paper and government agency discount notes with maturities
spread out over 44 days. The weighted average maturity of the portfolio on June
30, 1999, was 15.1 days reflecting the utilization of the money market for the
free-look period available to the variable insurance products.

INVESTMENT PROGRAM:
This Fund invests in a diversified portfolio of high-quality U.S. dollar-
denominated debt instruments that present minimal credit risk with remaining
maturities of 397 days or less.

 * The 7-day yield quotation more closely reflects the current earnings of the
   Fund than the total return quotation.

** Total returns for periods of less than one year are not annualized. This six-
   month return is cumulative.

The total return calculations found in this section are calculated at the Fund's
investment level and reflect the change in the net asset value (NAV), the
reinvestment of income dividends, and the deductions of Fund expenses. It does
not include other associated insurance contract costs. If it did, the
performance quoted above would be lower. More specific information regarding the
Fund expenses and insurance contract costs can be found in the Variable Annuity
and Variable Universal Life prospectuses. These NAV total return calculations
represent past performance which is no guarantee of future returns.

The graph above compares the performance of a $10,000 hypothetical investment
in the USAA Life Income Fund to two industry indexes which most closely
resemble the holdings of this Fund. The Lehman Brothers Aggregate Bond Index is
an unmanaged index made up of the government/corporate index, the mortgage-
backed securities index, and the asset-backed securities index. The Lipper A
Rated Bond Fund Index is an unmanaged index made up of funds investing in
corporate debt issues rated A or better or government issues.

The calculations for the Lehman Brothers and Lipper Indexes are based on a full
calendar year in 1995, whereas the Income Fund calculations are based on a
starting date of January 5, 1995 - the inception date of this Fund. This
comparison is for illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Manager J. W. Saunders, Jr.

MARKET CONDITIONS AND PERFORMANCE
Following a stable period in January 1999, interest rates began a steady upward
trend that depressed bond prices, which move inversely.

Economic strength in the first quarter of 1999, which is the fourth year in a
row for first quarter strength, has renewed inflation fears and the specter of
higher interest rates. A sharp increase in the Consumer Price Index (CPI) in
April, due primarily to increased oil prices, reinforced the inflation thesis
and May's CPI showed no change. However, the Federal Reserve (Fed) announced a
bias toward raising rates in mid-June as a preemptive move to thwart inflation,
and on June 30, 1999, did raise the Federal Funds lending rate to 5%, up 0.25%
from 4.75%. Yields on the 30-year Treasury bond have moved from 5.09% on January
1, 1999, to 6.05% on June 30, 1999, as shown in the following chart on page B-6.

INVESTMENT PROGRAM:
This Fund invests in a diversified portfolio of U.S. dollar-denominated debt and
income-producing equity securities selected for their high yields relative to
the risk involved.

*Total returns for periods of less than one year are not annualized. This six-
 month return is cumulative.

The total return calculations found in this section are calculated at the Fund's
investment level and reflect the change in the net asset value (NAV), the
reinvestment of income dividends, and the deductions of Fund expenses. It does
not include other associated insurance contract costs. If it did, the
performance quoted above would be lower. More specific information regarding the
Fund expenses and insurance contract costs can be found in the Variable Annuity
and Variable Universal Life prospectuses. These NAV total return calculations
represent past performance which is no guarantee of future returns.

In this rising interest rate environment, the Fund underperformed in its peer
group for this six-month period because of the portfolio's longer average
maturity. The Fund's high-income orientation tends to keep average maturity
longer. The Fund's average annual NAV total return for the six-month period
ended June 30, 1999, was -3.44% versus an average of -2.20% for all funds in the
Lipper Variable Insurance Products/1/ A Rated Bond Fund category for the same
period.

PORTFOLIO
As of June 30, 1999, the Fund's portfolio mix as percentages of net assets was
24.5% U. S. Treasury bonds, 48.7% agency mortgage pass-through securities, 15.5%
corporate bonds, and 10.2% preferred stocks.

OUTLOOK
The bond market has been unsettled for some time over the anticipated raising of
interest rates by the Federal Reserve. A heavy corporate calendar for new issue
bonds to be sold to reluctant buyers has created a one way path to the bond
market downside. Now that the Fed has raised rates, some of the conjecture is
over. In addition, the Fed has returned its bias for future interest rate action
to neutral. With yields on the long Treasury bond above 6%, this rise in
interest rates may be over for the time being. However, stability through the
summer may lead to new worries that the Federal Reserve Board will raise rates
again in the fall. This would unsettle the bond market again. The key is whether
the economic strength continues and/or the Consumer Price Index picks up, in
which case, the Federal Reserve will be more eager to tighten interest rates.

Data represent the last business of each month.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life Growth and Income Fund to the S&P 500(R) Index. The S&P 500 Index
is an unmanaged index representing the weighted average performance of a group
of 500 widely held, publicly traded stocks. It is not possible to invest
directly in the S&P 500 Index.

The calculations for the S&P 500 Index are based on a full calendar year in
1995, whereas the calculations for the  Growth and Income Fund are based on a
starting date of January 5, 1995-the inception date of this Fund. This
comparison is for illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Manager R. David Ullom

PERFORMANCE
For the six months ended June 30, 1999, the performance of the USAA Life Growth
and Income Fund showed considerable improvement on both an absolute basis and
relative to the S&P 500 Index. For this six-month period, the NAV total return
for the Fund was 16.64% versus a total return of 12.38% for the S&P 500 Index.

Performance for the first half of this year can be viewed in terms of two
distinctly different time frames. The first quarter of the year (through March
31) saw a continuation of the trends of 1998. In general, large capitalization
growth stocks continued to dominate the performance of the major indices.
However, beginning in April, many cyclical and/or commodity-oriented stocks
became top performers in the Fund. The stocks of companies, such as Alcoa, Deere
& Co., Weyerhaeuser, Millennium Chemicals, Boeing, B.F. Goodrich, and Lear,
appreciated in the range of 20% to 50% in the month of April. This compares to a
rise of 3.87% for the S&P 500 Index. During this same period, the stocks of many
high-growth companies, such as Merck & Co, Intel, Microsoft, and Oracle, fell.

INVESTMENT PROGRAM:
Not less than 65% of its assets are invested in a diversified portfolio of
dividend-paying common stocks and convertible securities of companies that offer
the prospect for growth of earnings.

*Total returns for periods of less than one year are not annualized. This
 six-month return is cumulative.

The total return calculations found in this section are calculated at the Fund's
investment level and reflect the change in the net asset value (NAV), the
reinvestment of income dividends, and the deductions of Fund expenses. It does
not include other associated insurance contract costs. If it did, the
performance quoted above would be lower. More specific information regarding the
Fund expenses and insurance contract costs can be found in the Variable Annuity
and Variable Universal Life prospectuses. These NAV total return calculations
represent past performance which is no guarantee of future returns.

             AN OVERVIEW (Continued)             JUNE 30, 1999

During the latter part of 1998 and into the first quarter of 1999, we undertook
and completed some changes in the portfolio investment strategy, which should
improve performance over the long term. Specifically, such alterations included
a more balanced weighting among the various economic sectors. We did this while
adhering to our stock selection parameters of focusing on companies with solid
earnings and earnings growth, and whose valuations appear attractive.

MARKET CONDITIONS AND OUTLOOK
Although the equity market has broadened in that a greater number of stocks have
risen this year, the volatility of the market is still a source of concern.
There remains a significant segment of investors who focus on short-term events
and news and, in turn, make investment decisions based on that information. A
second source of worry relates to the Federal Reserve (Fed) and interest rates.
By itself, the recent increase in interest rates is not a serious source of
concern. However, we doubt that equity markets will continue their rise should
the Fed decide to further increase interest rates.

STRATEGY
Our strategy continues to focus on quality companies that sell for compelling
valuations. As an example, we expect to continue favoring health care securities
(particularly pharmaceuticals), as they are reasonably priced and offer the
potential for earnings growth, even in a rising interest rate environment.

Data represent the last business day of each month.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life World Growth Fund to its benchmark, the Morgan Stanley Capital
Index (MSCI)-World, an unmanaged index which reflects the movement of world
stock markets by representing a broad selection of domestically listed companies
within each market.

Calculations for the Morgan Stanley Index are based on a full calendar year in
1995, whereas the World Growth Fund calculations are based on a starting date of
January 5, 1995-the inception date of this Fund. This comparison is for
illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Managers David G. Peebles, Curt Rohrman, Albert Sebastian, and W.
Travis Selmier, II

MARKET CONDITIONS
For the six month period ended June 30, 1999, the Fund's NAV total return was
10.48% as compared with the MSCI World Index return of 8.51% and the Lipper
Global Funds Average/1/ return of 11.33%.The Fund's performance did improve over
the last six months.

INTERNATIONAL
Europe-Most European equity markets rebounded from last year's declines, but
returns were negatively impacted in 1999 by weak European currencies despite the
introduction of the Euro. Central banks in Europe cut interest rates as economic
growth forecasts were revised downward, primarily because of weakness in the
German and Italian economies. After last year's sell off, cyclical and resource
stocks rebounded, based on stronger global economic forecasts and higher energy
prices. In general, the larger European equity market (e.g., United Kingdom)
outperformed the smaller ones (e.g., Portugal, Belgium) throughout the period.

INVESTMENT PROGRAM:
Not less than 65% of the Fund's assets are invested in a diversified
portfolio of common stocks and other equity securities of both foreign and
domestic issuers representing at least three countries, one of which may include
the United States. The remainder of the Fund's assets may  be invested in
marketable debt securities having remaining maturities of less than one year
which are issued or guaranteed  as to both principal and interest by the U.S.
government or by its agencies.

              AN OVERVIEW (Continued)            JUNE 30, 1999

Emerging Markets - Emerging markets have recovered from last year. Asian
equities' strong recovery has been driven by good export growth, the reversal of
deflation (reflation) in many economies, and capital flows into the stock market
and into acquisitions of Asian companies. Although Russia's economic and
political problems and the conflict in Kosovo will influence central European
and many Mediterranean markets, these markets look more to the European
community for their political and economic cues. Greece was the best performer
in the region. Israel's and South Africa's economic recovery, export strength,
and improving political prospects have validated our overweight position in
those markets. With the exception of a strong Mexican market, our lower
weighting in Latin markets throughout the last six months was validated by
Brazil's forced devaluation of its currency, the Real, in January.

Japan - Since the election last summer, Japanese politics have solidified, more
progress has been seen on Japan's banking crisis, and a raft of corporate
restructuring announcements has pushed the market up over the last eight months.
However, we will need to see follow-through on the corporate restructuring
coupled with stimulatory economic policy to push the market higher. Our
technology, telecommunications, and financial equity holdings helped us
outperform the Japanese equity market throughout the period.

           AN OVERVIEW (Continued)              JUNE 30, 1999

Canada and Australia - Although we have preferred Canadian to Australian
equities, both markets have rebounded from last year's declines. Our positions
in Canada benefited from higher energy prices, a swing back to cyclical stocks,
and a stronger Canadian dollar. The reverse trends for these same factors had
negatively impacted the performance of the Fund in the second half of 1998.

UNITED STATES
U.S. stocks performed strongly through the period. A combination of healthy
domestic economic growth, continued low inflation, and recovering overseas
economies provided an exceptional environment for accelerating earnings growth.
The fund benefited from its overweight position in technology and consumer
cyclicals. Technology stocks posted the best returns of any sector during the
period, driven by demand for products and services related to the Internet and
preparation for Y2K. The strong domestic economy was particularly important to
consumer cyclicals, including retailers.

OUTLOOK
U.S. based corporations may experience rising profits through 1999, as worldwide
economies recover. However, valuations are unlikely to expand materially because
the best inflation news is probably behind us. We continue to view Europe
positively but have slightly reduced our over-weight position in favor of other
markets. European valuations still look attractive, and Europe could continue to
benefit from merger and acquisition activity. Canada should benefit from higher
commodity prices and strong U.S. economic growth. The Japanese market will
likely be a mixed bag with some sectors doing well. Given a reflating global
economy, emerging markets should continue to perform well.

/1/ The Lipper Global Funds Average is the average performance level of all
    global funds, as reported by Lipper Analytical Services, an independent
    organization that monitors the performance of mutual funds.

    Foreign investing is subject to additional risks such as currency
    fluctuations, market illiquidity, and political instability which are
    discussed in the prospectus. Since return on any investment is generally
    commensurate with risk, investors should be aware of the potential
    volatility associated with foreign markets.

Data represent the last business of each month.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life Diversified Assets Fund to two industry indexes and an independent
rating agency's average which most closely resemble the holdings of this Fund.

The S&P 500 Index is an unmanaged index representing the weighted average
performance of a group of 500 widely held,  publicly traded stocks. It is not
possible to invest directly in the S&P 500 Index. The Lehman Brothers Aggregate
Bond Index is an unmanaged index made up of the government/corporate index, the
mortgage-backed securities index, and the asset-backed securities index. The
Lipper Balanced Fund Average is the average performance level of all variable
annuity balanced funds as reported by Lipper Analytical Services, an independent
organization that monitors the performance of variable annuity funds and mutual
funds.

The calculations for all indexes and averages are based on a full calendar year
in 1995, whereas the Diversified Assets Fund calculations are based on a
starting date of January 5, 1995 - the inception date of this Fund.

This comparison is for illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Managers R. David Ullom (Common Stocks) and Paul Lundmark (Debt
Securities)

PERFORMANCE
For the six months ended June 30, 1999, the USAA Life Diversified Assets Fund's
NAV total return was 10.55%. A performance discussion of the Fund's two sectors
is found below.

Common Stocks - Performance of the common stock sector of the USAA Life
Diversified Assets Fund improved relative to the S&P 500 Index. The sector's
performance can be virtually divided into two equal time periods, with the first
quarter favoring large capitalization growth stocks and the second quarter
(beginning in April) favoring commodity and cyclical stocks. As a result,
performance for the first half of the period was helped by the Fund's exposure
to basic materials (Alcoa), capital goods (Boeing, B.F. Goodrich, Deere & Co.,
and Caterpiller), and energy (Occidental Petroleum, Chevron, and Texaco).
However, during the same period, the Fund's weighting in health care (more
specifically, drugs) hindered performance. Also, although underweighted relative
to the S&P 500 Index, our positions in technology generally hurt performance.

                       USAA LIFE DIVERSIFIED ASSETS FUND

          AN OVERVIEW (Continued)               JUNE 30, 1999

Debt Securities - Within the Fund's bond portion, the best performing holdings
were the Collateralized Mortgage Obligations (CMOs). These instruments are
defensive in nature and will outperform most other debt securities in a rising
interest rate environment. The debt securities of Real Estate Investment Trusts
(REITs) also performed relatively well. REITs have rebounded since the last
quarter of 1998 as investors saw that the negative market sentiment towards this
asset class had become overdone.

MARKET CONDITIONS
Common Stocks - As mentioned in the previous discussion above, beginning in
April of this year, the equity markets began to broaden and favor the stocks of
more economically sensitive companies. This change in sentiment appears to have
resulted from signs that the economies of Southeast Asia are recovering and that
the Brazilian economy has stabilized. However, given the recent rise in interest
rates and uncertainties as to further rate increases, we do expect continued
market volatility.

Debt Securities - We manage the bond sector so that income is the primary
component of total return. Since the beginning of the year, interest rates have
risen dramatically and investors no longer expect a deflation scenario. Instead,
the fear is that a continuing strong economy will eventually cause inflation to
rise. In fact, the Federal Reserve Board recently increased overnight rates in
order to "cool down" the economy. Because of our income orientation, we have
favored investments in higher yielding instruments such as corporate bonds,
mortgage and asset-backed securities rather than Treasuries. This investment
style hurt us in the fall of 1998 but has now resulted in the bond sector
outperforming Treasuries this year.

          AN OVERVIEW (Continued)               JUNE 30, 1999

PORTFOLIO STRATEGY AND OUTLOOK
Common Stocks - Within the common stock allocation of the USAA Life Diversified
Assets Fund, we have continued to focus on quality companies where earnings
and/or earnings growth potential do not appear to be appropriately valued. Also
within the common stock allocation, we have undertaken a strategy of broadening
our diversification among the various economic sectors. For example, in the
technology sector, we have added some stocks that meet our purchase criteria.

Debt Securities - Since interest rates have increased dramatically, we
purchased a Treasury bond because it became an attractive investment. We also
purchased it for diversification purposes. However, the majority of the assets
in the bond sector will continue to be in corporates, mortgages and asset-backed
securities.

Looking to the future, we feel that the economy will remain strong, which will
result in corporates, mortgages and asset-backed securities increasing in
relative value. We also believe that trying to guess where interest rates are
going is a losing bet. We will continue to invest in securities that have good
risk/reward characteristics.

GENERAL DISCUSSION
By Portfolio Managers John K. Cabell and Eric M. Efron

THE MARKET
The stock market environment during the six-month period ended June 30, 1999,
did not vary meaningfully from the standard pattern of the past several years.
For the most part, corporate earnings were good. Additionally, the outlook for
economies around the world continued to be satisfactory in the aggregate, with
the U.S. and Europe strong, but possibly decelerating some. Also, Asia showed
initial signs of a gradual recovery from its recent economic and financial
crises. Prospects for an Asian recovery prompted some concern in the investment
community about rising inflation and interest rates, particularly in June, and
helped revive interest in cyclical stocks.

Although this blend of positives and negatives led to day-to-day volatility in
stock prices, the pluses ultimately prevailed, with all major indices higher at
the end of the period than in the beginning. The S&P 500 Index/1/, the Dow Jones
Industrial Average/2/, and the NASDAQ/3/-all of which are large cap centric-were
up by 12.38%, 20.48%, 22.50%, respectively for the six-month period ended June
30, 1999. Once again, small cap benchmarks such as the Russell 2000 Index and
the S&P Small Cap 600 Index/4/ brought up the rear, generating more modest
returns of 5.0% and 1.2%, respectively. This shows investors' continuing
preference for the liquidity and perceived safety of large cap stocks over the
better growth prospects and lower valuations of small cap equities.

INVESTMENT PROGRAM:

             AN OVERVIEW (Continued)              JUNE 30, 1999

PERFORMANCE
For the six-month period ended June 30, 1999, the Fund, which was invested
primarily in small to mid  cap growth companies, had a total return of 26.56%.
The Fund outperformed all the major market indices mentioned above.

PORTFOLIO STRATEGY
We believe that change is inevitable and central to existence whether it be life
forms, civilizations, governments, social institutions, economic systems, or
businesses. Those entities that embrace change are likely to succeed and thrive
whereas those that resist it are doomed to failure at worst and to extremely
limited prospects at best. With this in mind, we try to identify long-term
social and economic trends that are in their early stages and are potentially
powerful and pervasive. We then aggregate these trends into six overriding
themes - the telecommunications revolution, new computing, new products and
services, the drive for efficiency, changing lifestyles, and consolidation - and
look to invest in companies that are in a good position to benefit from the
changes that lie ahead.

In addition, we focus our investments on companies that are either growing
rapidly or have the potential to do so. We believe that rapid growth is one of
the best ways to build value over the long term. We are willing to pay premium
valuations for the companies in which we invest because we are confident that
the premiums will be paid off handsomely over time. We are firm believers of the
old adage that "you get what you pay for."

Our investments tend to focus on small to mid cap companies because this is
where most of the rapid growth and innovation that we desire is to be found.
Nevertheless, we will also invest in larger companies - Microsoft, Intel, Cisco,
Dell Computers, Clear Channel Communications, Infinity Broadcasting, and Home
Depot, for example - that possess the attributes we seek. We wish to stress that
the USAA Life Aggressive Growth Fund is not synonymous with small to mid cap;
instead, it transcends market capitalization categories.

We have overweighed our investments in the technology and communications areas.
The Internet (Network Solutions, Concentric Network, and STAR
Telecommunications) is rapidly transforming how we communicate, do business, and
live. At the same time, old telecommunications monopolies worldwide are
crumbling in the face of deregulation and competition, as new companies (Global
TeleSytems Group, Global Crossing, Qwest Communications International, Level 3
Communications) rise to provide the internet and other new services that
customers demand. Almost as rapidly as these new companies are being
established, companies within the industry are acquiring one another (Metromedia
Fiber Network/AboveNet Communications, VoiceStream Wireless/ Omnipoint) in order
to position themselves for dominance in the new telecommunications age. All of
this is stimulating huge demand for the networking and data communications
equipment (Cisco Systems, CIENA, Harmonic Lightwaves) that goes into the
telecommunications infrastructure and for the semiconduc-

tors (Vitesse Semiconductor, Applied Micro Circuits, Triquint Semiconductor, MMC
Networks) and other components (JDS Fitel) that go into the equipment.

All the companies mentioned here are holdings or recent sales in the Fund and
fit within the six major themes mentioned above. Taken together with our other
positions in the technology and communications areas, they contributed
significantly to our strong relative performance during the six-month period
ended June 30. It is very tempting to further overweight our investments in
these areas, but we refrain from doing so in order to limit risk. We also want
to take advantage of opportunities in other promising industries such as
retailing (Abercrombie & Fitch, 99 Cents Only Stores, Williams-Sonoma),
biotechnology (IDEC Pharmaceuticals, Immunex), health care (Express Scripts),
and financial services (Knight/Trimark Group).

OUTLOOK
Conditions continue to look positive for investors. Worldwide economies,
depending on locale, appear to be good or improving, but not at an explosive
pace. In addition, the outlook for corporate earnings is encouraging. There are
some concerns about inflation and interest rates, but they do not appear strong
enough to offset the positives.

At the same time, stock valuations are very high by many conventional standards,
and are subject to sharp downdrafts in the face of any negative news. Moreover,
from a geopolitical perspective, the world is not a pleasant place. Problems
abound, such as the deepening political partisanship and disenchantment in the
U.S., chronic instability in Russia, the Yugoslav/Kosovo situation, the ongoing
tensions between India and Pakistan over Kashmir, and North Korea's continuing
quarrels with its neighbors. The potential for the eruption of crises that could
undermine investor confidence is substantial.

As always, we counsel investors to expect volatility and to take it in stride.
In the event of a stock market correction, this Fund may be more volatile than
many others due to its large concentration of high valuation and low market
capitalization holdings. However, the long-term fundamentals underlying our
investments appear to be very sound, and, in our opinion, should support
meaningful price appreciation potential for patient, risk-tolerant investors.

GENERAL DISCUSSION
By Portfolio Managers W. Travis Selmier II, Albert Sebastian,
and David G. Peebles

MARKET CONDITIONS
For the six-month period ended June 30, 1999, the Fund's total NAV return was
6.10% as compared to the Lipper Global Funds Average/1/ return of 8.12% and the
Morgan Stanley Capital Index (MSCI)-EAFE return of 3.97%.

EUROPE
Most European equity markets rebounded from last year's declines, but returns
were negatively impacted in 1999 by weak European currencies despite the
introduction of the Euro. Central banks in Europe cut interest rates as economic
growth forecasts were revised downward, primarily because of weakness in the
German and Italian economies. After last year's sell off, cyclical and resource
stocks rebounded based on stronger global economic forecasts and higher energy
prices. In general, the larger European equity market (e.g., United Kingdom)
out-performed the smaller ones (e.g., Portugal, Belgium) throughout the period.

          AN OVERVIEW (Continued)                         June 30, 1999

CANADA AND AUSTRALIA
While we have preferred Canadian to Australian equities, both markets have
rebounded from last year's declines. Our positions in Canada benefited from
higher energy prices, a swing back to cyclical stocks, and a stronger Canadian
dollar. These same factors had negatively impacted the performance of the Fund
in the second half of 1998.

EMERGING MARKETS
Emerging markets have recovered from last year. Asian equities' strong recovery
has been driven by good export growth, the reversal of deflation (reflation) in
many economies, and capital flows into the stock market and acquisitions of
Asian companies. Although Russia's economic and political problems and the
conflict in Kosovo will influence central European and many Mediterranean
markets, these markets look more to the European community for their political
and economic cues. Greece is the best performer in the region. Israel's and
South Africa's economic recovery, export strength, and improving political
prospects have validated our overweight position in those markets. With the
exception of a strong Mexican market, our lower weighting in Latin markets
throughout the last six months was validated by Brazil's forced devaluation of
its currency, the Real, in January.

JAPAN
Since the election last summer, the Japanese political situation has solidified,
more progress has been seen on Japan's banking crisis, and a raft of corporate
restructuring announcements has pushed the market up over the last eight months.
However, we will need to see follow-through on the corporate restructuring
coupled with stimulatory economic policy to push the market higher. Our
technology, telecommunications, and financial equity holdings helped us
outperform the Japanese equity market throughout the period.

OUTLOOK
We continue to view Europe positively but have slightly reduced our overweight
position there in favor of other markets. European valuations still look
attractive, and Europe should continue to benefit from merger and acquisition
activity as well as economic recovery in the second half of 1999. Canada should
benefit from higher commodity prices and strong U.S. economic growth. The
Japanese market is likely to be a mixed bag with some sectors doing well. Given
a reflating global economy, emerging markets should continue to perform well.

Foreign investing is subject to additional risks such as currency fluctuations,
market illiquidity, and political instability which are discussed in the

investors should be aware of the potential volatility associated with foreign
markets.

                      NOTES TO PORTFOLIOS OF INVESTMENTS

                                                     June 30, 1999 (Unaudited)

GENERAL NOTES
Market values of securities are determined by procedures and practices discussed
in Note 1 to the Trust's financial statements.

The cost of securities for federal income tax purposes is approximately the same
as that reported in the financial statements.

The percentages shown represent the percentage of the investments to net assets.
At June 30, 1999, investments in foreign securities were 1.7% of the net assets
of the USAA Life Growth & Income Fund, 1.7% of the net assets of the USAA Life
Diversified Assets Fund, and 5.2% of the net assets of the USAA Life Aggressive
Growth Fund.

ADR - American Depositary Receipts are receipts issued by a U.S. bank evidencing
ownership of foreign shares.  Dividends are paid in U.S. dollars.

GDR - Global Depositary Receipts are receipts issued by a U.S. or foreign bank
evidencing ownership of foreign shares. Dividends are paid in U.S. dollars.

SPECIFIC NOTES
(a) Security is exempt from registration under the Securities Act of 1933 and
has been determined to be liquid by USAA Investment Management Company (the
Manager).  Any resale of this security may occur in an exempt transaction in the
United States to a qualified institutional buyer as defined by Rule 144A.

(b) Illiquid security valued using methods determined by the Trust's investment
adviser under the general supervision of the Board of Trustees. At June 30,
1999, these securities represented .54% and .77% of the USAA Life World Growth
Fund's and the USAA Life International Fund's net assets, respectively.

CATEGORIES AND DEFINITIONS

The securities in USAA Life Money Market Fund are divided into two categories -
fixed rate instruments and variable rate demand notes.

FIXED RATE INSTRUMENTS - consist of corporate and government notes and
commercial paper.  The yield is constant to maturity.  Prior to maturity, the
market price of a fixed-rate instrument generally varies inversely to the
movement of interest rates.

VARIABLE RATE DEMAND NOTES (VRDN) - provide the right, on any business day, to
sell the security at face value on either that day or in seven days. The
interest rate is adjusted at the stipulated daily, weekly, or monthly interval
to a rate that reflects current market conditions. In money market funds, the
effective maturity of these instruments is deemed to be less than 397 days in
accordance with detailed regulatory requirements.

CREDIT ENHANCEMENT - adds the financial strength of the provider of the
enhancement to support the issuer's ability to repay the principal when due. The
enhancement may be provided by either a high quality bank, insurance company, or
other corporation, or a collateral trust.

The USAA Life Money Market Fund's investments consist of securities meeting the
requirements to qualify as "eligible securities" under the Securities and
Exchange Commission (SEC) rules applicable to money market funds. The Manager
attempts to minimize credit risk in the USAA Life Money Market Fund through
rigorous internal credit research and by investing in securities rated in one of
the two highest categories for short-term securities, or, if not rated, of
comparable quality, at the time of purchase.

(LOC)- Enhanced by a bank letter of credit.

                         NOTES TO FINANCIAL STATEMENTS

                                                       June 30, 1999 (Unaudited)


1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USAA LIFE INVESTMENT TRUST (the Trust), registered under the Investment Company
Act of 1940, as amended, is a diversified, open-end management investment
company organized as a Delaware business trust consisting of seven separate
funds.

The investment objectives of the Funds are as follows:

USAA LIFE MONEY MARKET FUND: Highest level of current income consistent with
preservation of capital and maintenance of liquidity, through a diversified
portfolio of high quality U.S. dollar-denominated debt instruments that present
minimal credit risk and have remaining maturities of 397 days or less.

USAA LIFE INCOME FUND: Maximum current income without undue risk to principal,
through a diversified portfolio of U.S. dollar-denominated securities selected
for their high yields relative to the risk involved.

USAA LIFE GROWTH AND INCOME FUND: Capital growth and current income, through a
diversified portfolio of dividend paying equity securities.

USAA LIFE WORLD GROWTH FUND: Long-term capital appreciation, through a
diversified portfolio of equity securities of both foreign and domestic issuers.

USAA LIFE DIVERSIFIED ASSETS FUND: Long-term capital growth, consistent with
preservation of capital and balanced by current income, through a strategy of
investing approximately 60% of the Fund's assets in equity securities, selected
for their potential return, and approximately 40% of its assets in debt
securities of varying maturities.

USAA LIFE AGGRESSIVE GROWTH FUND: Appreciation of capital, through a portfolio
of equity securities of companies that have the prospect of rapidly growing
earnings.

USAA LIFE INTERNATIONAL FUND: Capital appreciation with a secondary objective of
current income, through a strategy of investing at least 80% of the Fund's
assets in equity securities of foreign companies.

Shares of the Funds currently are offered only to the Separate Accounts of USAA
Life Insurance Company (the Separate Accounts) to serve as the funding medium
for certain variable annuity contracts and variable universal life insurance
policies offered by USAA Life.

A.  SECURITY VALUATION - The value of each security is determined (as of the
close of trading on the New York Stock Exchange on each business day the
Exchange is open) as set forth below:

1. Portfolio securities, except as otherwise noted, traded primarily on a
domestic securities exchange are valued at the last sales price on that
exchange. Portfolio securities traded primarily on foreign securities exchanges
are generally valued at the closing values of such securities on the exchange
where primarily traded. If no sale is reported, the average of the bid and asked
prices is generally used depending upon local custom or regulation.

2. Over-the-counter securities are priced at the last sales price or, if not
available, at the average of the bid and asked prices.

3. Securities purchased with maturities of 60 days or less and, pursuant to Rule
2a-7 under the Investment Company Act of 1940, as amended, all securities in the
USAA Life Money Market Fund are stated at amortized cost which approximates
market value.

4. Other debt and government securities are valued each business day by a
pricing service (the Service) approved by the Funds' Board of Trustees. The
Service uses the mean between quoted bid and asked prices or the last sale price
to price securities when, in the Service's judgement, these prices are readily
available and are representative of the securities' market values. For many
securities, such prices are not readily available. The Service generally prices
these securities based on methods which include consideration of yields or
prices of securities of comparable quality, coupon, maturity and type,
indications as to values from dealers in securities, and general market
conditions.

5. Securities which cannot be valued by the methods set forth above, and all
other assets, are valued in good faith at fair value, using methods determined
by the investment adviser under the general supervision of the Board of
Trustees.

B. FEDERAL TAXES - The Funds' policy is to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of their income to their shareholders, the Separate
Accounts and USAA Life. Therefore, no federal income or excise tax provision is
required. As a result of certain permanent differences between book and tax
basis accounting, reclassifications have been made on the statement of assets
and liabilities of the USAA Life Diversified Assets Fund to increase paid-in
capital and decrease accumulated undistributed net investment income by $3,000
and on the statement of assets and liabilities of the USAA Life Aggressive
Growth Fund to increase paid-in capital and to decrease accumulated net realized
gain on investments by $3,000.

C. INVESTMENTS IN SECURITIES - Security transactions are accounted for on the
date the securities are purchased or sold (trade date).  Gain or loss from sales
of investment securities is computed on the identified cost basis.  Dividend
income, less foreign taxes, if any, is recorded on the ex-dividend date. If the
ex-dividend date has passed, certain dividends from foreign securities are
recorded upon notification.  Interest income is recorded on the accrual basis.
Discounts and premiums on short-term and long-term securities are amortized over
the life of the respective securities.

D. FOREIGN CURRENCY TRANSLATIONS - The assets of the USAA Life World Growth,
USAA Life Aggressive Growth, and USAA Life International Funds may be invested
in the securities of foreign issuers and may be traded in a foreign currency.
Since the accounting records of the Funds are maintained in U.S. dollars,
foreign currency amounts are translated into U.S. dollars on the following
basis:

1. Market value of securities, other assets, and liabilities at the mean between
the bid and asked translation rates of such currencies against U.S. dollars on a
daily basis.

2. Purchases and sales of securities, income, and expenses at the rate of
exchange obtained from an independent pricing service on the respective dates of
such transactions.

Net realized and unrealized foreign currency gains/losses occurring during the
holding period of investments are a component of realized gain/loss on
investments and unrealized appreciation/depreciation on investments,
respectively.

Net realized foreign currency gains/losses arise from sales of foreign currency,
from currency gains/losses realized between the trade and settlement dates on
security transactions, and from the difference between amounts of dividends,
interest, and foreign withholding taxes recorded on the Funds' books and the
U.S. dollar equivalent of the amounts received. Net realized foreign currency
gains/losses have been reclassified from accumulated net realized gain/loss to
accumulated undistributed net investment income on the statement of assets and
liabilities as such amounts are treated as ordinary income/loss for tax
purposes.  Net unrealized foreign currency exchange gains/losses arise from
changes in the value of assets and liabilities other than investments in
securities resulting from changes in the exchange rate.

E. USE OF ESTIMATES - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that may affect the reported amounts in the financial
statements.

2) DISTRIBUTIONS

USAA LIFE MONEY MARKET FUND

Net investment income is accrued daily as dividends and distributed monthly to
its shareholders, the Separate Accounts. All net investment income available for
distribution was distributed at June 30, 1999. Distributions of realized gains
from security transactions not offset by capital losses are made annually or as
otherwise required to avoid the payment of federal taxes.

USAA LIFE INCOME, USAA LIFE GROWTH AND INCOME, USAA LIFE WORLD GROWTH, USAA LIFE
DIVERSIFIED ASSETS, USAA LIFE AGGRESSIVE GROWTH, AND USAA LIFE INTERNATIONAL
FUNDS

Distributions of net investment income and realized gains from security
transactions not offset by capital losses are made to the shareholders, the
Separate Accounts and USAA Life, annually or as otherwise required to avoid the
payment of federal taxes.  USAA Life is a shareholder only in the USAA Life
World Growth, USAA Life Aggressive Growth, and USAA Life International Funds.

At June 30, 1999, the USAA Life International Fund had a capital loss carryover
for federal income tax purposes of $687,000 which, if not offset by subsequent
capital gains, will expire in 2006.  It is unlikely that the Board of Trustees
of the Fund will authorize a distribution of capital gains realized in the
future until the capital loss carryover has been utilized or expires.

4)  FOREIGN CURRENCY CONTRACTS

A forward currency contract (currency contract) is a commitment to purchase or
sell a foreign currency at a specified date, at a negotiated price.  The USAA
Life World Growth and USAA Life International Funds currently enter into
currency contracts only in connection with the purchase or sale of a security
denominated in a foreign currency. These contracts allow the Funds to "lock in"
the U.S. dollar price of the security.  Currency contracts are valued on a daily
basis using foreign currency exchange rates obtained from an independent pricing
service.  Risks of entering into currency contracts include the potential
inability of the counterparty to meet the terms of the contract and the Funds
foregoing the opportunity for potential profit.

At June 30, 1999, the terms of open foreign currency contracts were as follows:

5) TRANSACTIONS WITH AFFILIATES

A. ADVISORY FEES - USAA Investment Management Company (USAA IMCO) carries out
each Fund's investment policies and manages each Fund's portfolio. USAA IMCO is
indirectly wholly owned by USAA. The Funds' advisory fees are computed on an
annualized rate of .50% of the monthly average net assets of the USAA Life
Aggressive Growth Fund, .65% of the monthly average net assets of the USAA Life
International Fund, and .20% of the monthly average net assets for each of the
other Funds of the Trust for each calendar month.

B. ADMINISTRATIVE FEES - As outlined in the Underwriting and Administrative
Services Agreement by and between USAA Life, the Trust and USAA IMCO, USAA Life
provides certain management, administrative, legal, clerical, accounting, and
record-keeping services necessary or appropriate to conduct the Trust's business
and operations. Fees are based on estimated time spent to provide services.
Under a separate arrangement between USAA Life and USAA IMCO, USAA Life
delegates certain mutual fund accounting duties under the Underwriting and
Administrative Services Agreement to USAA IMCO and reimburses USAA IMCO for its
costs in providing these services.

C. EXPENSES REIMBURSED - USAA Life, out of its general account, has agreed to
pay directly or reimburse the Trust for Trust expenses to the extent that such
expenses exceed .65% of the monthly average net assets of the USAA Life World
Growth Fund,  .70% of the monthly average net assets of the USAA Life Aggressive
Growth Fund, 1.10% of the monthly average net assets of the USAA Life
International Fund, and .35% of the monthly average net assets of each other
Fund. Expenses include advisory and administrative fees discussed above.

D. UNDERWRITING AND ADMINISTRATIVE SERVICES AGREEMENT - The Trust has an
agreement with USAA IMCO for exclusive underwriting and distribution of the
Funds' shares on a continuing best efforts basis. USAA IMCO receives no
commissions or fees for this service.

E. BROKERAGE SERVICES - USAA Brokerage Services, a discount brokerage service of
USAA IMCO, may execute portfolio transactions for the Funds. The amount of
brokerage commissions paid to USAA Brokerage Services during the six-month
period ended June 30, 1999 for the USAA Life Growth and Income, and USAA Life
Diversified Assets Funds were $5,000 and $3,000 respectively.

F. SHARE OWNERSHIP - At June 30, 1999, USAA Life owned 600,000 shares (32%) of
the USAA Life World Growth Fund, 1.4 million shares (75%) of the USAA Life
Aggressive Growth Fund, and 2.0 million shares (93%) of the USAA Life
International Fund.  All other shares are owned by the Separate Accounts.

Certain trustees and officers of the Funds are also directors, officers, and/or
employees of USAA Life or USAA IMCO.  None of the affiliated trustees or Fund
officers received any compensation from the Funds.

6) YEAR 2000

Like other investment companies, the Trust could be adversely affected if the
computer systems used by USAA IMCO, USAA Life, and the Trust's other service
providers are not able to perform their intended functions effectively after
1999 because of the inability of computer software to distinguish the year 2000
from the year 1900.  USAA IMCO and USAA Life each have taken steps to address
this potential year 2000 problem with respect to the computer systems that they
use and to obtain satisfactory assurances that the comparable steps are being
taken by the Trust's other major service providers. At this time, however, there
can be no assurance that these steps will be sufficient to avoid any adverse
impact to the Trust from this problem.
